The 24-kDa protein encodes two conserved sequence motifs: the initial signal sequence targets the protein for secretion while the larger discoidin domain is implicated in cell adhesion. RS1 helps to maintain the structural organization of the retinal cell layers and promotes visual signal transduction. RS1 gene mutations cause X-linked retinoschisis disease (XLRS) in males, characterized by early-onset central vision loss. We analyzed the biochemical consequences of several RS1 signal-sequence mutants (c.1A>T, c.35T>A, c.38T>C, and c.52G>A) found in our subjects. Expression analysis in COS-7 cells demonstrates that these mutations affect RS1 biosynthesis and result in an RS1 null phenotype by several different mechanisms. By comparison, discoidin-domain mutations generally lead to nonfunctional conformational variants that remain trapped inside the cell. XLRS disease has a broad heterogeneity in general, but subjects with the RS1 null-protein signal-sequence mutations are on the more severe end of the clinical phenotype. Results from the signal-sequence mutants are discussed in the context of the discoidin-domain mutations, clinical phenotypes, genotype-phenotype correlations, and implications for RS1 gene replacement therapy.

We examined the association between in utero exposure to tobacco smoke and female fertility among women in the Norwegian Mother and Child Cohort Study, enrolled from 1999 to 2007. Around the 17th week of pregnancy, participants reported how long they took to conceive (time to pregnancy), and whether their mother smoked while pregnant with the participant. This analysis included 48 319 planned pregnancies among women aged 15-44 years. We estimated fecundability odds ratios (FORs) using a discrete-time survival analysis, adjusting for age, education and adult tobacco smoking. The adjusted FOR for in utero exposure to tobacco smoke among all subjects was 0.96 [95% confidence interval (CI): 0.93, 0.98], among subjects reporting no adult tobacco smoking or passive exposure it was 0.96 (95% CI: 0.93, 0.99) and among subjects reporting adult tobacco smoking or passive exposure it was 0.95 (95% CI: 0.91, 0.99). We performed a probabilistic sensitivity analysis to estimate the effect of exposure and outcome misclassification on the results, and, as expected, the association became more pronounced after taking misclassification into account. This large cohort study supports a small-to-modest association between in utero exposure to tobacco smoke and reduced fertility.

In animal studies, partial nephrectomy induces marinobufagenin elevation, cardiac hypertrophy, and fibrosis. The objective of this study is to test the effect of renal ischemia on marinobufagenin levels in humans with renal artery stenosis (RAS). To test this, plasma marinobufagenin levels were measured in patients with RAS of the Prospective Randomized Study Comparing Renal Artery Stenting With or Without Distal Protection, non-RAS patient controls who were scheduled for coronary angiography, and normal healthy individuals. Marinobufagenin levels were significantly higher in patients with RAS compared with those of the other 2 groups. Multivariate analysis shows that occurrence of RAS is independently related to marinobufagenin levels. In addition, renal artery revascularization by stenting partially reversed marinobufagenin levels in the patients with RAS (0.77 +/- 0.06 nmol/L at baseline; 0.66 +/- 0.06 nmol/L at 24 hours; and 0.61 +/- 0.05 nmol/L at 1 month). In conclusion, we have found that marinobufagenin levels are increased in patients with RAS, whereas reversal of renal ischemia by stenting treatment reduces marinobufagenin levels. These results suggest that RAS-induced renal ischemia may be a major cause of marinobufagenin release. (Hypertension. 2010;56:914-919.)

However, B-1 field inhomogeneity, which is particularly problematic at high field strengths ( e. g., 3T), limits the ability of the scanner to deliver the prescribed flip angle, introducing errors into the T-1 maps that limit the accuracy of quantitative analyses based on those maps. A dual repetition time method was used for acquiring a B-1 map to correct that inhomogeneity. Additional inaccuracies due to misregistration of the acquired T-1-weighted images were corrected by rigid registration, and the effects of misalignment on the T-1 maps were compared to those of B-1 inhomogeneity in 19 normal subjects. However, since B-1 map acquisition takes up precious scanning time and most retrospective studies do not have B-1 map, we designed a template-based correction strategy. B-1 maps from different subjects were aligned using a twelve-parameter affine registration. Recomputed T-1 maps showed an important improvement with respect to the noncorrected maps: histograms of all corrected maps exhibited two peaks corresponding to white and gray matter tissues, while unimodal histograms were observed in all uncorrected maps because of the inhomogeneity. A method to detect the best nonsubject-specific B-1 correction based on a set of features was designed. The optimum set of weighting factors for those features was computed. The best available B-1 correction was detected in almost all subjects while corrections comparable to the T-1 map corrected using the B-1 map from the same subject were detected in the others.

A novel Bayesian peptide ion peak detection method is proposed for TOF data with resolution of 10 000-15 000 full width at half-maximum (FWHW). MS spectra exhibit distinct characteristics at this resolution, which are captured in a novel parametric model. Based on the proposed parametric model, a Bayesian peak detection algorithm based on Markov chain Monte Carlo (MCMC) sampling is developed. The proposed algorithm is tested on both simulated and real datasets. The results show a significant improvement in detection performance over a commonly employed method. The results also agree with expert's visual inspection. Moreover, better detection consistency is achieved across MS datasets from patients with identical pathological condition.

Aspergillus fumigatus conidia are melanised and are weakly immunogenic. We show that melanin pigments on the surface of resting Aspergillus fumigatus conidia may serve to mask pathogen-associated molecular patterns (PAMPs)-induced cytokine response. The albino conidia induced significantly more proinflammatory cytokines in human peripheral blood mononuclear cells (PBMC), as compared to melanised wild-type conidia. Blocking dectin-1 receptor, Toll-like receptor 4 or mannose receptor decreased cytokine production induced by the albino but not by the wild type conidia. Moreover, albino conidia stimulated less potently, cytokine production in PBMC isolated from an individual with defective dectin-1, compared to the stimulation of cells isolated from healthy donors. These results suggest that beta-glucans, but also other stimulatory PAMPs like mannan derivatives, are exposed on conidial surface in the absence of melanin. Melanin may play a modulatory role by impeding the capability of host immune cells to respond to specific ligands on A. fumigatus. (C) 2009 Elsevier GmbH. All rights reserved. C1 [Chai, Louis Y.

They are also involved in the induction of autoimmune and allergic diseases. Upon T-cell receptor (TCR)-mediated cell activation, naive CD4+ T cells can differentiate into at least four major lineages, Th1, Th2, Th17, and iTreg cells, that participate in different types of immune responses. Networks of cytokines and transcription factors are critical for determining CD4+ T-cell fates and effector cytokine production. Here, we review collaboration and cross-regulation between various essential cytokines in the activation/induction of key transcription factors during the process of Th cell differentiation towards these distinct lineages. We also discuss the interactions of key transcription factors at both genetic and protein levels and the function of the resulting network(s) in regulating the expression of effector cytokines.

Toll-like receptors (TLRs) sense specific microbial products and direct downstream signaling pathways in immune cells, linking innate, and adaptive immunity. Here, we analyze the role of TLR2 on innate and adaptive immune responses during N. caninum infection. Inflammatory peritoneal macrophages and bone marrow-derived dendritic cells exposed to N. caninum-soluble antigens presented an upregulated expression of TLR2. Increased receptor expression was correlated to TLR2/MyD88-dependent antigen-presenting cell maturation and pro-inflammatory cytokine production after stimulation by antigens. Impaired innate responses observed after infection of mice genetically deficient for TLR2((-/-)) was followed by downregulation of adaptive T helper 1 (Th1) immunity, represented by diminished parasite-specific CD4(+) and CD8(+) T-cell proliferation, IFN-gamma:interleukin (IL)-10 ratio, and IgG subclass synthesis. In parallel, TLR2(-/-) mice presented higher parasite burden than wild-type (WT) mice at acute and chronic stages of infection. These results show that initial recognition of N. caninum by TLR2 participates in the generation of effector immune responses against N. caninum and imply that the receptor may be a target for future prophylactic strategies against neosporosis.

In some STEC-infected individuals, a life-threatening sequela of infection called the hemolytic uremic syndrome may develop that can lead to kidney failure. This syndrome is linked to the production of Stx by the infecting organism. For Stx to reach the kidney, the toxin must first penetrate the colonic epithelial barrier. However, the Stx receptor, globotriaosylceramide (Gb3), has been thought to be absent from human intestinal epithelial cells. Thus, the mechanisms by which the toxin associates with and traverses through the intestine en route to the kidneys have been puzzling aspects of STEC pathogenesis. In this study, we initially determined that both types of Stx made by STEC, Stx1 and Stx2, do in fact bind to colonic epithelia in fresh tissue sections and to a colonic epithelial cell line (HCT-8). We also discovered that globotetraosylceramide (Gb4), a lower-affinity toxin receptor derived from Gb3, is readily detectable on the surfaces of human colonic tissue sections and HCT-8 cells. Furthermore, we found that Gb3 is present on a fraction of HCT-8 cells, where it presumably functions to bind and internalize Stx1 and Stx2. In addition, we established by quantitative real-time PCR (qRT-PCR) that both fresh colonic epithelial sections and HCT-8 cells express Gb3 synthase mRNA. Taken together, our data suggest that Gb3 may be present in small quantities in human colonic epithelia, where it may compete for Stx binding with the more abundantly expressed glycosphingolipid Gb4.

TI New Candidate Vaccines against Blood-Stage Plasmodium falciparum Malaria: Prime-Boost Immunization Regimens Incorporating Human and Simian Adenoviral Vectors and Poxviral Vectors Expressing an Optimized Antigen Based on Merozoite Surface Protein 1 SO INFECTION AND IMMUNITY LA English DT Article ID CARBOXYL-TERMINAL FRAGMENT; T-CELL EPITOPES; PROTECTIVE IMMUNITY; ANTIBODY-RESPONSES; PARASITE GROWTH; RHESUS-MONKEYS; CLINICAL-TRIAL; LIVER STAGE; IN-VITRO; YOELII AB Although merozoite surface protein 1 (MSP-1) is a leading candidate vaccine antigen for blood-stage malaria, its efficacy in clinical trials has been limited in part by antigenic polymorphism and potentially by the inability of protein-in-adjuvant vaccines to induce strong cellular immunity. Here we report the design of novel vectored Plasmodium falciparum vaccines capable of overcoming such limitations. We optimized an antigenic insert comprising the four conserved blocks of MSP-1 fused to tandemly arranged sequences that represent both allelic forms of the dimorphic 42-kDa C-terminal region. Inserts were expressed by adenoviral and poxviral vectors and employed in heterologous prime-boost regimens. Simian adenoviral vectors were used in an effort to circumvent preexisting immunity to human adenoviruses. In preclinical studies these vaccines induced potent cellular immune responses and high-titer antibodies directed against MSP-1. The antibodies induced were found to have growth-inhibitory activity against dimorphic allelic families of P. falciparum. These vectored vaccines should allow assessment in humans of the safety and efficacy of inducing strong cellular as well as cross-strain humoral immunity to P. falciparum MSP-1.

Here we report on the design, chemical synthesis, and immunogenicity of three Plasmodium falciparum MAP vaccines that incorporated antigenic epitopes from the sporozoite, liver, and blood stages of the life cycle. Antibody and cellular responses were determined in three inbred (C57BL/6, BALB/c, and A/J) strains, one congenic (HLA-A2 on the C57BL/6 background) strain, and one outbred strain (CD1) of mice. All three MAPs were immunogenic and induced both antibody and cellular responses, albeit in a somewhat genetically restricted manner. Antibodies against MAP-1, MAP-2, and MAP-3 had an antiparasite effect that was also dependent on the mouse major histocompatibility complex background. Anti-MAP-1 (CSP-based) antibodies blocked the invasion of HepG2 liver cells by P. falciparum sporozoites (highest, 95.16% in HLA-A2 C57BL/6; lowest, 11.21% in BALB/c). Furthermore, antibodies generated following immunizations with the MAP-2 (PfCSP, PfLSA-1, PfMSP-1(42), and PfMSP-3b) and MAP-3 (PfRAP-1, PfRAP-2, PfSERA, and PfMSP-1(42)) vaccines were able to reduce the growth of blood stage parasites in erythrocyte cultures to various degrees. Thus, MAP-based vaccines remain a viable option to induce effective antibody and cellular responses. These results warrant further development and preclinical and clinical testing of the next generation of candidate MAP vaccines that are based on the conserved protective epitopes from Plasmodium antigens that are widely recognized by populations of divergent HLA types from around the world.

Design Historical review. Setting Global events in a variety of circumstances over more than 3,000 years time. Sample Comprehensive review of the historical literature including all major publications on pandemic and panzootic influenza. Main Outcome Measures Influenza pandemics, panzootics, major epidemics and epizootics, and instances of interspecies transmission of influenza A. Results Extensive documentation of human and animal influenza over many centuries suggests that influenza A viruses have adapted to a variety of species and environmental milieu and are capable of switching between many different hosts under widely varying circumstances. Conclusions The genetic elements of influenza A viruses circulate globally in an extensive ecosystem comprised of many avian and mammalian species and a spectrum of environments. Unstable gene constellations found in avian species become stable viruses only upon switching to secondary hosts, but may then adapt and circulate independently. It may be desirable to think of influenza A viruses as existing and evolving in a large ecosystem involving multiple hosts and environments. Implications for understanding human influenza are discusssed. C1 [Morens, David M.] NIAID, NIH, OD, Bethesda, MD 20892 USA.

SO INFLUENZA AND OTHER RESPIRATORY VIRUSES LA English DT Article; Proceedings Paper CT International Symposium on Neglected Influenza Viruses CY FEB 03-05, 2010 CL Amelia Island, FL DE Avian influenza; epizootic; equine influenza; highly pathogenic avian influenza; influenza poultry ID PANDEMIC INFLUENZA AB Background An explosive fatal epizootic in poultry, prairie chickens, turkeys, ducks and geese, occurred over much of the populated United States between 15 November and 15 December 1872. To our knowledge the scientific literature contains no mention of the nationwide 1872 poultry outbreak. Objective To understand avian influenza in a historical context. Results The epizootic progressed in temporal-geographic association with a well-reported panzootic of equine influenza that had begun in Canada during the last few days of September 1872. The 1872 avian epizootic was universally attributed at the time to equine influenza, a disease then of unknown etiology but widely believed to be caused by the same transmissible respiratory agent that caused human influenza. Conclusions Another microbial agent could have caused the avian outbreak; however, its strong temporal and geographic association with the equine panzootic, and its clinical and epidemiologic features, are most consistent with highly pathogenic avian influenza. The avian epizootic could thus have been an early instance of highly pathogenic avian influenza. C1 [Morens, David M.; Taubenberger, Jeffery K.] NIAID, NIH, Bethesda, MD 20892 USA.

Alternatives to this scenario are also discussed. Successful blood-feeding requires adaptations to antagonize the vertebrate's mechanisms of blood clotting, platelet aggregation, vasoconstriction, pain and itching, which are triggered by tissue destruction and immune reactions to insect products. Saliva of these insects provides a complex pharmacological armamentarium to block these vertebrate reactions. With the advent of transcriptomics, the sialomes (from the Greek word sialo = saliva) of at least two species of each of these families have been studied (except for the frog feeders), allowing an insight into the diverse pathways leading to today's salivary composition within the Culicomorpha, having the sand flies as an outgroup. This review catalogs 1288 salivary proteins in 10 generic classes comprising over 150 different protein families, most of which we have no functional knowledge. These proteins and many sequence comparisons are displayed in a hyperlinked spreadsheet that hopefully will stimulate and facilitate the task of functional characterization of these proteins, and their possible use as novel pharmacological agents and epidemiological markers of insect vector exposure.

The transcription factor heat shock factor 1 (HSF1) has been implicated in extending lifespan in part by increasing expression of heat shock response genes. Pyrrolidine dithiocarbamate (PDTC) is a small thiol compound that exerts in vivo and in vitro anti-inflammatory properties through mechanisms that remain unclear. Here we report that PDTC induced the release of monomeric HSF1 from the molecular chaperone heat shock protein 90 (Hsp90), with concomitant increase in HSF1 trimer formation, translocation to the nucleus, and binding to promoter of target genes in human HepG2 cells. siRNA-mediated silencing of HSF1 blocked BAG3 gene expression by PDTC. The protein levels of the cochaperone BAG3 and its interaction partner Hsp72 were stimulated by PDTC in a dose-dependent fashion, peaking at 6 h. Inhibition of Hsp90 function by geldanamycin derivatives and novobiocin elicited a pattern of FISH activation and BAG3 expression that was similar to PDTC. Chromatin immunoprecipitation studies showed that PDTC and the inhibitor 17-dimethylaminoethylamino-17-demethoxygeldanamycin enhanced the binding of HSF1 to the promoter of several target genes, including BAG3, HSPA1A, HSPA1B, FKBP4, STIP1 and UBB. Cell treatment with PDTC increased significantly the level of Hsp90 alpha thiol oxidation, a posttranslational modification known to inhibit its chaperone function. These results unravel a previously unrecognized mechanism by which PDTC and related compounds could confer cellular protection against inflammation through HSF1-induced expression of heat shock response genes.

Our previous study showed that injections of matched normal spleen cells with Complete Freund's Adjuvant (CFA) reversed salivary gland dysfunction in 14-week-old NOD mice, which had established Ss. The spleen and bone marrow are closely related organs, and both are among the first sites of hematopoiesis during gestation. Noticing a rapidly increasing number of clinical trials using bone marrow (BM) cells treatments for autoimmune diseases, we tested if BM cells can prevent Ss and restore salivary glands' function. We injected CFA and MHC class I-matched normal BM cells in 7-week-old NOD mice, which had not yet developed Ss. We found at week 52 post-treatment that all NOD mice receiving BM cells and CFA had a recovery of salivary flow and were protected from Ss and diabetes. BM cells-treated mice had their salivary function restored quantitatively and qualitatively. Saliva flow was higher (p < 0.05) in BM cells-transplanted mice when compared to control mice, which continued to deteriorate over time. Total proteins, epidermal growth factor, amylase, and electrolytes concentrations in saliva of BM cells-treated mice were not significantly changed at week 44 and 52 post-therapy when compared to pre-therapy (when the mice did not have Ss). Restoration of salivary flow could have resulted from a combination of rescue and paracrine effects from BM cells. This study suggests that a combined immuno- and cell-based therapy can permanently prevent Ss and restored salivary function in NOD mice. (C) 2010 Elsevier Ltd. All rights reserved.

Osmolytes and CDA ligands were used to increase the yield and the specific activity of the protein. The mutant enzyme was purified and subjected to a kinetic characterization and to stability studies. These investigations reinforced the hypothesis that in human CDA the side chain of Y33 is involved in intersubunit interactions with four glutamate residues (E108) forming a double latch that connects each of the two pairs of monomers of the tetrameric CDA.

The involvement of the viscera is usually secondary to bulky and extensive serosal disease. We describe 7 cases of mesothelioma in which the initial manifestation was that of an ovarian mass. All patients underwent surgery with a primary diagnosis of ovarian cancer. Clinical histories, gross features, and histology slides were reviewed. Immunostains were performed on all cases and electron microscopy was performed in 2 cases. The patients ranged in age from 22 to 52 years and the lesions ranged in size from 3.8 to 9 cm. Of the 7 cases, 4 were predominantly cystic and 3 were solid. Histologically, all cystic tumors were multicystic mesothelioma, whereas the 3 solid tumors were diffuse malignant mesotheliomas. One patient had a borderline mucinous tumor with the mesothelioma occurring as a mural nodule, an association not described earlier. The oldest patient in this series had a diffuse malignant mesothelioma of the peritoneum with predominant ovarian surface involvement. Mesothelial neoplasms can present as ovarian masses in young women. Awareness of this presentation is important to establish appropriate management.

Methods and Materials: A single 25-Gy dose of irradiation (IR) was delivered to parotid glands of 6 miniature pigs. Three other animals served as non-IR controls. Local blood flow rate in glands was measured pre- and post-IR with an ultrasonic Doppler analyzer. Samples of parotid gland tissue were taken at 4 h, 24 h, 1 week, and 2 weeks after IR for microvascular density (MVD) analysis and sphingomyelinase (SMase) assay. Histopathology and immunohistochemical staining (anti-CD31 and anti-AQP1) were used to assess morphological changes. MVD was determined by calculating the number of CD31- or AQP1-stained cells per field. A terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) apoptosis assay was used to detect apoptotic cells. The activity of acid and neutral Mg2+-dependent SMase (ASMase and NSMase, respectively) was also assayed. Results: Local parotid gland blood flow rate decreased rapidly at 4 h post-IR and remained below control levels throughout the 14-day observation period. Parotid MVD also declined from 4 to 24 hours and remained below control levels thereafter. The activity levels of ASMase and NSMase in parotid glands increased rapidly from 4 to 24 h post-IR and then declined gradually. The frequency of detecting apoptotic nuclei in the glands followed similar kinetics. Conclusions: Single-dose IR led to a significant reduction of MVD and local blood flow rate, indicating marked damage to microvascular endothelial cells in miniature pig parotid glands. The significant and rapid increases of ASMase and NSMase activity levels may be important in this IR-induced damage. (C) 2010 Elsevier Inc.

We investigated whether AIDS-defining pulmonary infections (recurrent pneumonia, Pneumocystis jirovecii pneumonia, and pulmonary tuberculosis) affected the risk of subsequent lung cancer over 10 years after AIDS onset among 322,675 PWA, whose records were linked with cancer registries in 11 US regions. We assessed lung cancer hazard ratios (HRs) using Cox regression and indirectly adjusted HRs for confounding by smoking. Individuals with recurrent pneumonia (n = 5317) were at significantly higher lung cancer risk than those without [HR = 1.63, 95% confidence interval (CI) = 1.08 to 2.46, adjusted for age, race, sex, HIV acquisition mode, CD4 count, and AIDS diagnosis year]. This association was especially strong among young PWA (<50 years HR = 1.99 vs. >= 50 years HR = 1.10) and was significantly elevated during 5-10 years after recurrent pneumonia diagnosis (HR = 2.41; 95% CI = 1.07 to 5.47). Although attenuated, HRs for recurrent pneumonia remained nonsignificantly elevated after indirect adjustment for smoking. Lung cancer risk was unrelated to tuberculosis [(n = 13,878) HR = 1.12, 95% CI = 0.82 to 1.53] or Pneumocystis jirovecii pneumonia [(n = 69,771) HR = 0.97, 95% CI = 0.80 to 1.18]. The increased lung cancer risk associated with recurrent pneumonia supports the hypothesis that chronic pulmonary inflammation arising from infections contributes to lung carcinogenesis.

Our goal was to evaluate a multidimensional adherence interview designed to improve on existing adherence measures. Data from caregivers (N = 126) of perinatally infected children were analyzed to determine the ability of the revised interview guide to detect potential treatment nonadherence. Questions related to viral load (VL) on a bivariate level included proportion of doses taken in the previous 3 days and 6 months, caregivers' knowledge of prescribed dosing frequencies, and caregivers' reports of problems associated with medication administration. VL was not associated with 3-day recall of missed doses. In multivariate analyses, only caregivers' knowledge of prescribed dosing frequencies was uniquely associated with VL. Our modified interview appears to successfully identify family struggles with adherence and to have the capacity to help clinicians address medication adherence challenges.

The increasing incidence of breast cancer in Asia and the limitations of existing treatments pose additional challenges. In this review, we summarize the preclinical and clinical evidence that indicates how lapatinib, a novel inhibitor that targets the human epidermal growth factor receptor (ErbB1) and ErbB2 may help clinicians address four particularly challenging issues in the management of ErbB2+ breast cancer. These issues are: (i) trastuzumab therapy failure, (ii) development of central nervous system metastases, (iii) minimizing toxicity and (iv) selecting the most appropriate partners (chemotherapy and non-chemotherapy) for combination therapy with lapatinib. Lapatinib, in combination with chemotherapeutic agents, such as capecitabine, provides clinical benefits to patients with ErbB2+ breast cancer, including patients who develop progressive disease on trastuzumab. Lapatinib, in combination with non-chemotherapeutic agents, such as letrozole, may also provide a chemotherapy-free treatment option for postmenopausal patients with estrogen receptor-positive/ErbB2+ metastatic breast cancer. Encouraging results have also emerged regarding the synergistic effects of lapatinib in combination with other agents for the treatment of ErbB2+ breast cancer. Promising findings have also been reported for the use of lapatinib to prevent and treat central nervous system metastases. Collectively, these results indicate that the judicious use of lapatinib, an effective oral therapy with a manageable toxicity profile, can enhance the management of patients with ErbB2+ breast cancer.

TI Developing Constructs for Psychopathology Research: Research Domain Criteria SO JOURNAL OF ABNORMAL PSYCHOLOGY LA English DT Article DE RDoC; psychopathology research constructs; research diagnoses ID MEDIAL PREFRONTAL CORTEX; FEAR; COGNITION; OXYTOCIN; AUTISM; SCHIZOPHRENIA; VASOPRESSIN; MECHANISMS; EMOTION; EXPRESSION AB There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple disruptions in putative mechanistic factors (e.g., excessive fear, deficient impulse control), and different disrupted mechanisms appear to play major roles in many disorders. The Research Domain Criteria (RDoC) framework is a heuristic to facilitate the incorporation of behavioral neuroscience in the study of psychopathology. Such integration might be achieved by shifting the central research focus of the field away from clinical description to more squarely examine aberrant mechanisms. RDoC first aims to identify reliable and valid psychological and biological mechanisms and their disruptions, with an eventual goal of understanding how anomalies in these mechanisms drive psychiatric symptoms. This approach will require new methods to ascertain samples, relying on hypothesized psychopathological mechanisms to define experimental groups instead of traditional diagnostic categories. RDoC, by design, uncouples research efforts from clinically familiar categories to focus directly on fundamental mechanisms of psychopathology. RDoC proposes a matrix of domains and levels of analyses and invites the field to test and refine the framework. If RDoC is successful, the domains will ultimately relate to familiar psychopathologies in ways that promote new knowledge regarding etiology and more efficient development of new preventive and treatment interventions.

This paper is a report of a study of the type, frequency, and level of stress of ethical issues encountered by nurses in their everyday practice. Background. Everyday ethical issues in nursing practice attract little attention but can create stress for nurses. Nurses often feel uncomfortable in addressing the ethical issues they encounter in patient care. Methods. A self-administered survey was sent in 2004 to 1000 nurses in four states in four different census regions of the United States of America. The adjusted response rate was 52%. Data were analysed using descriptive statistics, cross-tabulations and Pearson correlations. Results. A total of 422 questionnaires were used in the analysis. The five most frequently occurring and most stressful ethical and patient care issues were protecting patients' rights; autonomy and informed consent to treatment; staffing patterns; advanced care planning; and surrogate decision-making. Other common occurrences were unethical practices of healthcare professionals; breaches of patient confidentiality or right to privacy; and end-of-life decision-making. Younger nurses and those with fewer years of experience encountered ethical issues more frequently and reported higher levels of stress. Nurses from different regions also experienced specific types of ethical problems more commonly. Conclusion. Nurses face daily ethical challenges in the provision of quality care. To retain nurses, targeted ethics-related interventions that address caring for an increasingly complex patient population are needed.

It is estimated that around 250,000 people die prematurely each year as a result of asthma. Concepts of asthma severity and control are important in evaluating patients and their response to treatment, as well as for public health, registries, and research (clinical trials, epidemiologic, genetic, and mechanistic studies), but the terminology applied is not standardized, and terms are often used interchangeably. A common international approach is favored to define severe asthma, uncontrolled asthma, and when the 2 coincide, although adaptation may be required in accordance with local conditions. A World Health Organization meeting was convened April 5-6, 2009, to propose a uniform definition of severe asthma. An article was written by a group of experts and reviewed by the Global Alliance against Chronic Respiratory Diseases review group. Severe asthma is defined by the level of current clinical control and risks as "Uncontrolled asthma which can result in risk of frequent severe exacerbations (or death) and/or adverse reactions to medications and/or chronic morbidity (including impaired lung function or reduced lung growth in children)." Severe asthma includes 3 groups, each carrying different public health messages and challenges: (1) untreated severe asthma, (2) difficult-to-treat severe asthma, and (3) treatment-resistant severe asthma. The last group includes asthma for which control is not achieved despite the highest level of recommended treatment and asthma for which control can be maintained only with the highest level of recommended treatment.

In this study, we focused on comparisons between play of Down Syndrome (DS) children with their two parents as well as on comparisons between the two parents' play behaviours. Method Altogether 40 parent-child dyads participated: 20 children with DS (M age = 36.14 months) with their mothers and separately with their fathers. We coded participants' play behaviours during child solitary and mother-child and father-child collaborative sessions. Results Although children increased exploratory play from solitary to collaborative sessions with both parents, symbolic play increased only during joint play with fathers. Fathers displayed less symbolic and more exploratory activity compared to mothers. Mothers and fathers alike were attuned to their children, although fathers showed a higher degree of attunement. Conclusions This study shows that maternal and paternal contributions to DS child play skills are positive but different. During collaborative play children received specific and nonoverlapping scaffolding from their two parents, and fathers' contributions were unique.

For these studies we developed transgenic mice that express a membrane-tethered form of a model self antigen, chicken ovalbumin (mOVA), under the control of a keratin 14 (K14) promoter. K14-mOVA transgenic mice that express OVA mRNA and protein in the epithelia have been assessed for their immune responsiveness to OVA and are being used as targets for T cells obtained from OT-1 transgenic mice whose CD8+ T cells carry a V alpha 2/V beta 5-transgenic T cell receptor with specificity for the OVA(257-264)-peptides (OVAp) in association with class I MHC antigens. Some of the K14-mOVA transgenic mice develop a graft-versus-host-like disease (GvHD) when the OT-1 cells are injected while others appear to be tolerant to the OT-1 cells. We found that gamma c cytokines, especially IL-15, determine whether autoimmunity or tolerance ensues in K14-mOVA Tg mice. We also developed transgenic mice that express soluble OVA under the control of a K14 promoter (K14-sOVA) that die within 5-8 days after adoptive transfer of OT-1 cells and identified these mice as a model for more acute GvHD-like reactions. Spontaneous autoimmunity occurs when these K14-sOVA mice are crossed with the OT-I mice. In contrast, we found that preventive or therapeutic OVAp injections induced a dose-dependent increase in survival. In this review the characterization of 5 strains of K14-OVATg mice and underlying mechanisms involved in autoimmune reactions in these Tg mice are discussed. We also describe a strategy to break tolerance and describe how the autoimmunity can be obviated using OVAp. Finally, a historical overview of using transgenic mice to assess the mechanisms of tolerance is also provided. Published by Elsevier Ltd.

The sRNAs DsrA and RprA stimulate the translation of the stress response transcription factor RpoS by base pairing with the 5' untranslated region of the rpoS mRNA. In the present study, we found that the rpoS mRNA was unstable in the absence of DsrA and RprA and that expression of these sRNAs increased both the accumulation and the half-life of the rpoS mRNA. Mutations in dsrA, rprA, or rpoS that disrupt the predicted pairing sequences and reduce translation of RpoS also destabilize the rpoS mRNA. We found that the rpoS mRNA accumulates in an RNase E mutant strain in the absence of sRNA expression and, therefore, is degraded by an RNase E-mediated mechanism. DsrA expression is required, however, for maximal translation even when rpoS mRNA is abundant. This suggests that DsrA protects rpoS mRNA from degradation by RNase E and that DsrA has a further activity in stimulating RpoS protein synthesis. rpoS mRNA is subject to degradation by an additional pathway, mediated by RNase III, which, in contrast to the RNase E-mediated pathway, occurs in the presence and absence of DsrA or RprA. rpoS mRNA and RpoS protein levels are increased in an RNase III mutant strain with or without the sRNAs, suggesting that the role of RNase III in this context is to reduce the translation of RpoS even when the sRNAs are acting to stimulate translation.

TI A Mutation within the beta Subunit of Escherichia coli RNA Polymerase Impairs Transcription from Bacteriophage T4 Middle Promoters SO JOURNAL OF BACTERIOLOGY LA English DT Article ID ACTIVATOR MOTA INTERACTS; SIGMA(70) SUBUNIT; ASIA PROTEIN; ANGSTROM RESOLUTION; CRYSTAL-STRUCTURE; STRUCTURAL BASIS; DNA-REPLICATION; FLAP DOMAIN; T4 ASIA; GENE AB During infection of Escherichia coli, bacteriophage T4 usurps the host transcriptional machinery, redirecting it to the expression of early, middle, and late phage genes. Middle genes, whose expression begins about 1 min postinfection, are transcribed both from the extension of early RNA into middle genes and by the activation of T4 middle promoters. Middle-promoter activation requires the T4 transcriptional activator MotA and coactivator AsiA, which are known to interact with sigma(70), the specificity subunit of RNA polymerase. T4 motA amber [motA(Am)] or asiA(Am) phage grows poorly in wild-type E. coli. However, previous work has found that T4 motA(Am) does not grow in the E. coli mutant strain TabG. We show here that the RNA polymerase in TabG contains two mutations within its beta-subunit gene: rpoB(E835K) and rpoB(G1249D). We find that the G1249D mutation is responsible for restricting the growth of either T4 motA(Am) or asiA(Am) and for impairing transcription from MotA/AsiA-activated middle promoters in vivo. With one exception, transcription from tested T4 early promoters is either unaffected or, in some cases, even increases, and there is no significant growth phenotype for the rpoB(E835K G1249D) strain in the absence of T4 infection. In reported structures of thermophilic RNA polymerase, the G1249 residue is located immediately adjacent to a hydrophobic pocket, called the switch 3 loop. This loop is thought to aid in the separation of the RNA from the DNA-RNA hybrid as RNA enters the RNA exit channel. Our results suggest that the presence of MotA and AsiA may impair the function of this loop or that this portion of the beta subunit may influence interactions among MotA, AsiA, and RNA polymerase.

The big challenge of measuring FOS noninvasively lies in the presumably low signal-to-noise ratio. Thus, detectability of the FOS has been controversially discussed. We present reliable detection of FOS from 11 individuals concurrently with electroencephalogram (EEG) during a Go-NoGo task. Probes were placed bilaterally over prefrontal cortex. Independent component analysis (ICA) was used for artifact removal. Correlation coefficient in the best correlated FOS EEG ICA pairs was highly significant (p < 10(-8)), and event-related optical signal (EROS) was found in all subjects. Several EROS components were similar to the event-related potential (ERP) components. The most robust "optical N200" at t = 225 ms coincided with the N200 ERP; both signals showed significant difference between targets and nontargets, and their timing correlated with subject's reaction time. Correlation between FOS and EEG even in single trials provides further evidence that at least some FOS components "reflect" electrical brain processes directly. The data provide evidence for the early involvement of prefrontal cortex in rapid object recognition. EROS is highly localized and can provide cost-effective imaging tools for cortical mapping of cognitive processes.

The radiolabeled compound bound to preformed tubulin polymer in amounts stoichiometric with the polymer's tubulin content, with an apparent K-d value of 0.35 mu M. A less active peloruside A analogue, (11-R)-peloruside A and laulimalide acted as competitive inhibitors of the binding of the [H-3]peloruside A, with apparent K-i values of 9.3 and 0.25 mu M, respectively. Paclitaxel, epothilone B, and discodermolide had essentially no ability to inhibit [H-3]peloruside A binding, confirming that these compounds bind to a different site on tubulin polymer. We modeled both laulimalide and peloruside A into the binding site on beta-tubulin that was identified by Huzil et al. (J. Mol. Biol. 2008, 378, 1016-1030), but our model provides a more reasonable structural basis for the protein-ligand interaction. There is a more complete desolvation of the peloruside A ligand and a greater array of favorable hydrophobic and electrostatic interactions exhibited by peloruside A at its beta-tubulin binding site. In addition, the protein architecture in our peloruside A binding model was suitable for binding laulimalide. With the generation of both laulimalide and peloruside A binding models, it was possible to delineate the structural basis for the greater activity of laulimalide relative to peloruside A and to rationalize the known structure-activity relationship data for both compounds.

TI Urinary Cortisol and Six-Year Risk of All-Cause and Cardiovascular Mortality SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID PITUITARY-ADRENAL AXIS; METABOLIC SYNDROME; MYOCARDIAL-INFARCTION; ADIPOSE-TISSUE; BLOOD-PRESSURE; STRESS; DISEASE; CALCIFICATION; INFLAMMATION; DECLINE AB Context: The stress hormone cortisol has been linked with unfavorable cardiovascular risk factors, but longitudinal studies examining whether high levels of cortisol predict cardiovascular mortality are largely absent. Objective: The aim of this study was to examine whether urinary cortisol levels predict all-cause and cardiovascular mortality over 6 yr of follow-up in a general population of older persons. Design and Setting: Participants were part of the InCHIANTI study, a prospective cohort study in the older general population with 6 yr of follow-up. Participants: We studied 861 participants aged 65 yr and older. Main Outcome Measure: Twenty-four-hour urinary cortisol levels were assessed at baseline. In the following 6 yr, all-cause and cardiovascular mortality was ascertained from death certificates. Cardiovascular mortality included deaths due to ischemic heart disease and cerebrovascular disease. Results: During a mean follow-up of 5.7 (SD = 1.2) yr, 183 persons died, of whom 41 died from cardiovascular disease. After adjustment for sociodemographics, health indicators, and baseline cardiovascular disease, urinary cortisol did not increase the risk of noncardiovascular mortality, but it did increase cardiovascular mortality risk. Persons in the highest tertile of urinary cortisol had a five times increased risk of dying of cardiovascular disease (hazard ratio = 5.00; 95% confidence interval = 2.02-12.37). This effect was found to be consistent across persons with and without cardiovascular disease at baseline (p interaction = 0.78). Conclusions: High cortisol levels strongly predict cardiovascular death among persons both with and without preexisting cardiovascular disease. The specific link with cardiovascular mortality, and not other causes of mortality, suggests that high cortisol levels might be particularly damaging to the cardiovascular system.

TI Differences in Insulin Resistance in Mexican and U.S. Pima Indians with Normal Glucose Tolerance SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID DIABETES-MELLITUS; PHYSICAL-ACTIVITY; ENZYMATIC DETERMINATION; PLASMA-GLUCOSE; PATHOGENESIS; CHOLESTEROL; POPULATIONS; DYSFUNCTION; OBESITY; RISK AB Context: Insulin resistance is a major risk factor for the development of type 2 diabetes in Pima Indians, a population with the highest prevalence of type 2 diabetes mellitus in the world. Their Mexican counterpart, living a traditional lifestyle in the mountains of Sonora, have at least 5 times less diabetes than the U. S. Pima Indians. Objective: We evaluated whether Mexican Pima Indians had lower insulin resistance than U. S. Pima Indians. Design and Patients: We compared fasting insulin and homeostasis model assessment for insulin resistance (HOMA-IR) in 194 Mexican Pima Indians (100 females, 94 males) and 449 U. S. Pima Indians (246 females, 203 males) with normal glucose tolerance from a cross-sectional study. Adjusted differences of log-transformed outcomes (fasting insulin and HOMA-IR) between groups were evaluated using multiple linear regression models and paired t test in a matched subset. Results: Unadjusted fasting insulin and HOMA-IR were much lower in the Mexican Pima Indians than in their U. S. counterparts. After adjusting by obesity, age, and sex, mean (95% confidence interval) for fasting insulin was 6.22 (5.34-7.24) vs. 13.56 mu U/ml (12.27-14.97) and for HOMA-IR 1.40 (1.20-1.64) vs. 3.07 (2.77-3.40), respectively, for Mexican Pima and U. S. Pima Indians. Results were confirmed in subset matched for age, sex, and body fat. Conclusion: Our results indicate that Mexican Pima Indians have lower insulin resistance in comparison with their genetically related U. S. counterparts, even after controlling for differences in obesity, age, and sex. This finding underscores the importance of lifestyle factors as protecting factors against insulin resistance in individuals with a high propensity to develop diabetes.

Infiltration of muscle by fat predicts increased risk of hip fracture. Objective: We investigated whether fat infiltration of muscle, which is greater in diabetic adults, is associated with all clinical fracture and whether it accounts for the increased fracture risk in those with diabetes. Design, Setting, and Participants: Data were analyzed from the Health, Aging, and Body Composition Study, a cohort of community-dwelling adults aged 70-79 yr. Glucose metabolism status and x-ray attenuation of thigh muscle were determined at baseline for 2762 participants. Main Outcome Measures: During a mean 8.2 +/- 2.3 yr follow-up, 331 participants reported at least one clinical fracture. Results: Fat infiltration of muscle was higher in those with diabetes or impaired glucose metabolism than in those with normal glucose metabolism (P < 0.001). Fat infiltration of muscle was independently associated with a 19% increased risk of incident clinical fracture (multivariate hazard ratio = 1.19; 95% confidence interval = 1.04-1.36); this association did not differ across glucose metabolism groups (P for interaction = 0.65). As previously reported, diabetes was associated with a greater fracture risk compared with normal glucose metabolism (hazard ratio = 1.42; 95% confidence interval = 1.07-1.89) after adjustment for bone mineral density, but further adjustment for fat infiltration of muscle did not attenuate this association. Conclusions: Fat infiltration of muscle predicts clinical fracture in older adults. Although fat infiltration of muscle is higher among those with diabetes, it does not account for their increased fracture risk.

Study Design and Setting: We compared demographics and self-rated health of the PROMIS general Internet sample (N = 11,796) and one of its subsamples (n = 2,196) selected to approximate the joint distribution of demographics from the 2000 U.S. Census, with three national surveys and U.S. Census data. The comparisons were conducted using equivalence testing with weights created for PROMIS by raking. Results: The weighted PROMIS population and subsample had similar demographics compared with the 2000 U.S. Census, except that the subsample had a higher percentage of people with higher education than high school. Equivalence testing shows similarity between PROMIS general population and national norms with regard to body mass index, EQ-5D health index (EuroQol group defined descriptive system of health-related quality of life states consisting of five dimensions including mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and self-rating of general health. Conclusion: Self-rated health of the PROMIS general population is similar to that of existing samples from the general U.S. population. The weighted PROMIS general population is more comparable to national norms than the unweighted population with regard to subject characteristics. The findings suggest that the representativeness of the Internet data is comparable to those from probability-based general population samples. (C) 2010 Elsevier Inc. All rights reserved.

The Patient-Reported Outcomes Measurement Information System (PROMIS) provides item banks that offer the potential for efficient (minimizes item number without compromising reliability), flexible (enables optional use of interchangeable items), and precise (has minimal error in estimate) measurement of commonly studied PROs. We report results from the first large-scale testing of PROMIS items. Study Design and Setting: Fourteen item pools were tested in the U.S. general population and clinical groups using an online panel and clinic recruitment. A scale-setting subsample was created reflecting demographics proportional to the 2000 U.S. census. Results: Using item-response theory (graded response model), 11 item banks were calibrated on a sample of 21,133, measuring components of self-reported physical, mental, and social health, along with a 10-item Global Health Scale. Short forms from each bank were developed and compared with the overall bank and with other well-validated and widely accepted ("legacy") measures. All item banks demonstrated good reliability across most of the score distributions. Construct validity was supported by moderate to strong correlations with legacy measures. Conclusion: PROMIS item banks and their short forms provide evidence that they are reliable and precise measures of generic symptoms and functional reports comparable to legacy instruments. Further testing will continue to validate and test PROMIS items and banks in diverse clinical populations. (C) 2010 Elsevier Inc. All rights reserved.

We report on the HRQL impact of individual and comorbid conditions as well as conditions that are described as limiting activity. Study Design and Setting: Data were collected through online and clinic recruitment as part of the PROMIS item calibration sample (n = 21,133). Participants reported the presence or absence of 24 chronic health conditions and whether their activity was limited by each condition. Results: Across health status domains, the presence of a chronic condition was associated with poorer scores than those without a diagnosis, particularly for those individuals who reported that their condition was disabling. The magnitude of detriment in HRQL was more pronounced for individuals with two or more chronic conditions and could not be explained by sociodemographic factors. Patterns of HRQL deficits varied across disease and comorbidity status. Conclusion: The impact of chronic conditions, particularly when experienced with comorbid disease, is associated with detriments in HRQL. The negative impact on HRQL varies across symptoms and functional areas within a given condition. (C) 2010 Elsevier Inc. All rights reserved.

NOS2 upregulation and increased nitric oxide (NO) production affect the redox state of cells and can induce protein, lipid, and DNA modifications. To investigate whether NOS2 levels influence survival of breast cancer patients, we examined NOS2 expression and its association with tumor markers and survival in 248 breast tumors. In multivariable survival analysis, increased NOS2 predicted inferior survival in women with estrogen receptor alpha-negative (ER-negative) tumors. Microdissected tumor epithelium from ER-negative tumors with high NOS2 had increased IL-8 and a gene expression signature characteristic of basal-like breast cancer with poor prognosis. In cell culture, NO only induced selected signature genes in ER-negative breast cancer cells. ER transgene expression in ER-negative cells inhibited NO-induced upregulation of the stem cell marker CD44 and other proteins encoded by signature genes, but not of IL-8. Exposure to NO also enhanced cell motility and invasion of ER-negative cells. Last, pathway analysis linked the tumor NOS2 gene signature to c-Myc activation. Thus, NOS2 is associated with a basal-like transcription pattern and poor survival of ER-negative patients.

Immunologic approaches targeting tumor vasculature provide a means for the therapy of multiple solid tumor types. We developed a method to target tumor vasculature, using genetically redirected syngeneic or autologous T cells. Mouse and human T cells were engineered to express a chimeric antigen receptor (CAR) targeted against VEGFR-2, which is overexpressed in tumor vasculature and is responsible for VEGF-mediated tumor progression and metastasis. Mouse and human T cells expressing the relevant VEGFR-2 CARs mediated specific immune responses against VEGFR-2 protein as well as VEGFR-2-expressing cells in vitro. A single dose of VEGFR-2 CAR-engineered mouse T cells plus exogenous IL-2 significantly inhibited the growth of 5 different types of established, vascularized syngeneic tumors in 2 different strains of mice and prolonged the survival of mice. T cells transduced. with VEGFR-2 CAR showed durable and increased tumor infiltration, correlating with their antitumor effect. This approach provides a potential method for the gene therapy of a variety of human cancers: C1 [Chinnasamy, Dhanalakshmi; Yu, Zhiya; Theoret, Marc R.; Zhao, Yangbing; Shrimali, Rajeev K.; Morgan, Richard A.; Feldman, Steven A.; Restifo, Nicholas P.; Rosenberg, Steven A.] NCI, Surg Branch, Clin Res Ctr, Bethesda, MD 20892 USA.

Interactions between fetal trophoblast and maternal uterine NK (uNK) cells - specifically interactions between HLA-C molecules expressed by the fetal trophoblast cells and killer Ig-like receptors (KIRs) on the maternal uNK cells - influence placentation in human pregnancy. Consistent with this, pregnancies are at increased risk of preeclampsia in mothers homozygous for KIR haplotype A (KIR AA). In this study, we have demonstrated that trophoblast expresses both paternally and maternally inherited HLA-C surface proteins and that maternal KIR AA frequencies are increased in affected pregnancies only when the fetus has more group 2 HLA-C genes (C2) than the mother. These data raise the possibility that there is a deleterious allogeneic effect stemming from paternal C2. We found that this effect also occurred in other pregnancy disorders (fetal growth restriction and recurrent miscarriage), indicating a role early in gestation for these receptor/ligand pairs in the pathogenesis of reproductive failure. Notably, pregnancy disorders were less frequent in mothers that possessed the telomeric end of the KIR B haplotype, which contains activating KIR2DS1. In addition, uNK cells expressed KIR2DS1, which bound specifically to C2(+) trophoblast cells. These findings highlight the complexity and central importance of specific combinations of activating KIR and HLA-C in maternal-fetal immune interactions that determine reproductive success.

Pro, Barbara TI Temsirolimus Has Activity in Non-Mantle Cell Non-Hodgkin's Lymphoma Subtypes: The University of Chicago Phase II Consortium SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID RAPAMYCIN INHIBITOR EVEROLIMUS; MAMMALIAN TARGET; FOLLICULAR LYMPHOMA; CYCLIN D1; C-MYC; MTOR; CANCER; TRIAL; ACTIVATION; EXPRESSION AB Purpose Despite high initial remission rates, most lymphomas relapse and require further therapy. The mammalian target of rapamycin (mTOR) pathway is a validated target in mantle cell lymphoma, but has not been extensively evaluated in other lymphomas. Patients and Methods We performed a phase II trial of single-agent temsirolimus 25-mg weekly in patients with relapsed aggressive and indolent lymphomas. The primary objective was overall and complete response rate. Patients were stratified by histology: group A (diffuse large B-cell lymphoma, transformed follicular lymphoma), group B (follicular lymphoma), and group C (chronic lymphocytic leukemia/small lymphocytic lymphoma, and other indolent lymphomas). Results Eighty-nine patients were treated, with outcome strongly dependent on histology. Group A had an overall and complete response rate of 28.1% and 12.5%, respectively, and median progression-free survival (PFS) of 2.6 months and median overall survival (OS) of 7.2 months. Group B had overall and complete response rates of 53.8% and 25.6%, respectively, and median PFS of 12.7 months; median OS has not yet been reached. Group C had a partial response rate of 11% with no complete responders. Toxicity was mainly mild and/or reversible myelosuppression and mucositis; however, four patients developed pneumonitis. Conclusions Single-agent temsirolimus has significant activity in both diffuse large B-cell lymphoma and follicular lymphoma, although the durability of responses and PFS are longer for patients with follicular lymphoma. This is the first report of substantial activity of temsirolimus in lymphomas other than mantle cell lymphoma, and supports further evaluation of mTOR as a target in these diseases.

Despite the fact that it is a core aspect of the clinical presentation of bipolar disorder, the neurobiology of the switch process is still poorly understood. In this review, we summarize the clinical evidence regarding somatic interventions associated with switching, with a particular focus on the biologic underpinnings presumably involved in the switch process. Data Sources: Literature for this review was obtained through a search of the MEDLINE database (1966-2008) using the following keywords and phrases: switch, bipolar disorder, bipolar depression, antidepressant, SSRIs, tricyclic antidepressants, norepinephrine, serotonin, treatment emergent affective switch, mania, hypomania, HPA-axis, glucocorticoids, amphetamine, dopamine, and sleep deprivation. Study Selection: All English-language, peer-reviewed, published literature, including randomized controlled studies, naturalistic and open-label studies, and case reports, were eligible for inclusion. Data Synthesis: Converging evidence suggests that certain pharmacologic and nonpharmacologic interventions with very different mechanisms of action, such as sleep deprivation, exogenous corticosteroids, and dopaminergic agonists, can trigger mood episode switches in patients with bipolar disorder. The switch-inducing potential of antidepressants is unclear, although tricyclic antidepressants, which confer higher risk of switching than other classes of antidepressants, are a possible exception. Several neurobiological factors appear to be associated with both spontaneous and treatment-emergent mood episode switches; these include abnormalities in catecholamine levels, up-regulation of neurotrophic and neuroplastic factors, hypothalamic-pituitary-adrenal axis hyperactivity, and circadian rhythms. Conclusions: There is a clear need to improve our understanding of the neurobiology of the switch process; research in this field would benefit from the systematic and integrated assessment of variables associated with switching.

These areas contain a matching distribution of TIP39's receptor, the parathyroid hormone receptor 2 (PTH2R). Frequent PTH2R coexpression with a vesicular glutamate transporter (VGlut2) suggests that TIP39 could presynaptically regulate glutamate release. By using immunohistochemistry we found CRH-ir neurons surrounded by PTH2R-ir fibers and TIP39-ir axonal projections in the PVN area of the mouse brain. Labeling hypothalamic neuroendocrine neurons by peripheral injection of fluorogold in PTH2-RlacZ knock-in mice showed that most PTH2Rs are on PVN and peri-PVN interneurons and not on neuroendocrine cells. Double fluorescent in situ hybridization revealed a high level of coexpression between PTH2R and VGlut2 mRNA by cells located in the PVN and nearby brain areas. Local TIP39 infusion (100 pmol) robustly increased pCREB-ir in the PVN and adjacent perinuclear zone. It also increased plasma corticosterone and decreased plasma prolactin. These effects of TIP39 on pCREB-ir, corticosterone, and prolactin were abolished by coinfusion of the ionotropic glutamate receptor antagonists 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) and DL-2-amino-5-phosphonopentanoic acid (AP-5; 30 pmol each) and were absent in PTH2R knockout mice. Basal plasma corticosterone was slightly decreased in TIP39 knockout mice just before onset of their active phase. The present data indicate that the TIP39 ligand/PTH2 receptor system provides facilitatory regulation of the hypothalamic-pituitary-adrenal axis via hypothalamic glutamatergic neurons and that it may regulate other neuroendocrine systems by a similar mechanism.

Gregg TI An IGF1/insulin receptor substrate-1 pathway stimulates a mitotic kinase (cdk1) in the uterine epithelium during the proliferative response to estradiol SO JOURNAL OF ENDOCRINOLOGY LA English DT Article ID CYCLIN-DEPENDENT KINASES; FACTOR-I RECEPTOR; CELL-CYCLE; GROWTH-FACTOR; HISTONE H1; M-PHASE; TARGETED DISRUPTION; SIGNAL-TRANSDUCTION; NULL MUTATION; RAT UTERUS AB Estrogens are potent mitogens for some target organs, such as the uterus, and cancers that develop in this organ might be linked to the proliferative action of these hormones. However, the mechanism by which estrogens influence the cell cycle machinery is not known. We found that a null mutation for the insulin receptor substrate (IRS)-1, a docking protein that is important for IGF1 signaling, compromised hormone-induced mitosis in the uterine epithelium; BrdU incorporation was not affected. This selective effect on mitosis was associated with a reduction in uterine cyclin B-associated kinase activity; cyclin A-associated kinase activity was not changed. The null mutation also reduced the extent of hormone-induced phosphorylation of endogenous uterine histone H1, as determined with phospho-specific antiserum. Uterine epithelial cyclin dependent kinase (cdk)1 was induced in response to hormone, but the level of the kinase protein, as determined by immunoblotting, was noticeably less in the irs1 null mutant than that in the wild-type (WT) mouse, especially around the time of peak mitosis (24 h). Since IRS-1 binds/activates phosphatidylinositol 3-kinase (PI3K), the absence of this docking protein could impair signaling of a known pathway downstream of AKT that stimulates translation of cell cycle components. Indeed, we found that phosphorylation of uterine AKT (Ser473) in irs1 null mutants was less than that in WTs following treatment. Based on earlier studies, it is also possible that an IGF1/IRS-1/PI3K/AKT pathway regulates posttranslational changes in cdk1. This model may provide insights as to how a growth factor pathway can mediate hormone action on cell proliferation.

However, little is known about the role that specialists or generalists may play in reducing racial and ethnic disparities in uptake of new medical technologies. Human papillomavirus (HPV) DNA tests, introduced as a cervical cancer screening tool in 2000, present a rich context for exploring patterns of use across patient and provider subgroups. OBJECTIVE: To identify patient characteristics and the provider specially associated with overall and appropriate use of HPV DNA tests over time, and to examine the associations between clinical guidelines and adoption of the test in an underserved population. DESIGN: Retrospective longitudinal study using Florida Medicaid administrative claims data. PARTICIPANTS: Cervical cancer screening test claims for 415,239 female beneficiaries ages 21 to 64 from July 2001 through June 2006. MAIN MEASURES: Overall and appropriate use of HPV DNA tests. KEY RESULTS: Although minority women were initially less likely than White women to receive HPV DNA tests, test use grew more rapidly among Black and Hispanic women compared to White women. Obstetricians/gynecologists were significantly more likely than primary care providers to administer HPV DNA tests. Release of the first set of clinical guidelines was associated with a large increase in the use of HPV DNA tests (adjusted odds ratio: 2.46, p<0.0001); subsequent guidelines were associated with more modest increases. CONCLUSIONS: Uptake of new cervical cancer screening protocols can occur quickly among traditionally underserved groups and may be aided by early adoption by specialists.

Participants: Three military samples, including 2 nonclinical samples (n = 2420, n = 4244) and 1 sample of individuals with recent head injury (n = 617). Methods: In the first sample, exploratory factor analysis of Neurobehavioral Symptom Inventory responses was performed with tests of significant factors and model fit. In the other 2 samples, confirmatory factor analysis evaluated the fit of 3 models: 2- and 3-factor models based on the initial exploratory factor analysis, and a 9-factor model based on prior research. Main Outcome Measures: The exploratory factor analysis used 2 tests for the number of factors: Parallel Analysis and Minimum Average Partial test. Confirmatory factor analysis models were evaluated using 2 measures of model fit, Root Mean Square Error of Approximation and Comparative Fit Index. Results: Postconcussive symptoms can be described accurately by the 9 factors. However, the model of 3 intercorrelated factors, reflecting cognitive, affective, and somatic/sensory symptoms, fits the data more parsimoniously with little loss in model fit. Conclusion: Although the 9-cluster result from prior research provides a valid description of the relations among items of the inventory, a 3-factor model, consisting of somatic/sensory, affective, and cognitive factors, provides nearly as good a fit to the data, with greater parsimony. We encourage clinicians and researchers to conceptualize the Neurobehavioral Symptom Inventory in terms of 3 coherent clusters of symptoms rather than as 22 individual items.

To determine the priorities of low-income urban residents for interventions that address the socio-economic determinants of health. Methods. We selected and estimated the cost of 16 interventions related to education, housing, nutrition, employment, health care, healthy behavior, neighborhood improvement, and transportation. Low-income residents of Washington, D.C. (N=431) participated in decision exercises to prioritize these interventions. Results. Given a budget valued at approximately twice an estimated cost of medical and dental care ($885), the interventions ultimately prioritized by the greatest percentage of individuals were: health insurance (95%), housing vouchers (82%) dental care (82%), job training (72%), adult education (63%), counseling (68%), healthy behavior incentives (68%), and job placement (67%). The percentages of respondents who received support for housing, adult education, and job training and placement were far less than the percentage who prioritized these interventions. Conclusions. Poor and low-income residents' priorities may usefully inform allocation of social services that affect health.

However, the mechanism by which let-7 miRNAs are coordinately repressed is unclear. The RNA-binding proteins lin28 and lin28B block let-7 precursors from being processed to mature miRNAs, suggesting that their overexpression might promote malignancy through repression of let-7. Here we show that lin28 and lin28B are overexpressed in primary human tumors and human cancer cell lines (overall frequency approximately 15%), and that overexpression is linked to repression of let-7 family miRNAs and derepression of let-7 targets. lin28 and lin28b facilitate cellular transformation in vitro, and overexpression is associated with advanced disease across multiple tumor types. Our work provides a mechanism for the coordinate repression of let-7 miRNAs observed in a subset of human cancers, and associates activation of lin28 and lin28B with poor clinical prognosis.

The prototype device consists of p53 protein immobilized at various concentrations on a glass slide. The device is designed as a reference control to be used with assays that incorporate commercially available anti-p53 antibodies. p53 protein was characterized by mass spectrometry and covalently immobilized through amide linkage to the (3-aminopropyl)trietoxysilane-modified glass surface. This procedure is reproducible and provides a chemically stable product in high yield. The surface-bound protein was shown to be immunoreactive by its specific interaction with anti-p53 antibody (Ab) and detection by absorbance and fluorescence spectroscopy. Also, comparison was made with microscopic images of Ab-stained tissue samples, known to stain positive for p53. Further development will be required to establish accurate surface protein concentrations in the range required for specific clinical applications.

Because the signaling pathway and the resultant microbicidal activity are defective in HIV-infected patients, the mechanism by which STAT5 leads to granulysin expression is of great interest. In the current study, IL-2-stimulated CRL-2105 CD4(+) T cells expressed granulysin and killed Cryptococcus neoformans similar to primary CD4(+) T cells. The enhancer activity of the upstream element of the granulysin promoter was analyzed in primary CD4(+) T cells and CRL-2105 T cells with a luciferase reporter assay, and a STAT5 binding site, 18,302 to 18,177 bp upstream of the transcription start site, was identified as an enhancer. Additionally, the enhancer functioned in the context of heterologous SV40 promoter irrespective of its transcriptional orientation. Chromatin immunoprecipitation and EMSAs demonstrated that the enhancer element bound STAT5 both in vivo and in vitro, and mutation of the STAT5 binding site abrogated its enhancer activity. Furthermore, overexpression of a dominant negative STAT5a abolished the enhancer activity of the STAT5 binding site and abrogated the anticryptococcal activity of IL-2-stimulated primary CD4(+) T cells. Taken together, these data provide details about the complex regulation leading to granulysin expression and anticryptococcal activity in primary CD4(+) T cells.

In this study, we examined HIV-infected individuals with active virus replication (n = 15), treated with antiretroviral therapy (n = 13), and healthy controls (n = 11) and conducted a comparative analysis of T cells derived from blood and four gastrointestinal (GI) sites (terminal ileum, right colon, left colon, and sigmoid colon). As expected, we found that HIV infection is associated with depletion of total CD4(+) T cells as well as CD4(+) CCR5(+) T cells in all GI sites, with higher levels of these cells found in ART-treated individuals than in those with active virus replication. While the levels of both CD4(+) and CD8(+) T cell proliferation were higher in the blood of untreated HIV-infected individuals, only CD4(+) T cell proliferation was significantly increased in the gut of the same patients. We also noted that the levels of CD4(+) T cells and the percentages of CD4(+)Ki67(+) proliferating T cells are inversely correlated in both blood and intestinal tissues, thus suggesting that CD4(+) T cell homeostasis is similarly affected by HIV infection in these distinct anatomic compartments. Importantly, the level of intestinal CD4(+) T cells (both total and Th17 cells) was inversely correlated with the percentage of circulating CD4(+)Ki67(+) T cells. Collectively, these data confirm that the GI tract is a key player in the immunopathogenesis of HIV infection, and they reveal a strong association between the destruction of intestinal CD4(+) T cell homeostasis in the gut and the level of systemic CD4(+) T cell activation.

Clinical expanded NK-cell products were compared with freshly isolated NK cells. Autologous peripheral blood mononuclear cells were collected by apheresis from 8 patients. NK cells were isolated by anti-CD3-negative selection followed by anti-CD56-positive selection. They were then expanded by co-culture with interleukin-2 and an irradiated Epstein-Barr virus (EBV)-transformed lymphoblastoid cell line (EBV-TM-LCL) to produce 14 NK-cell products. Molecular changes in the 14 NK-cell products were characterized using gene and microRNA expression microarrays. EBV-TM-LCL feeder cells from 3 lots were also analyzed as they were expanded for over 90 days and each lot was used for multiple NK-cell expansions. The gene expression profiles among the 3 EBV-TM-LCL lots used showed no differences and were not affected by their time in culture. Freshly isolated and expanded NK cells had distinct gene and microRNA expression profiles. Compared with fresh NK cells, expanded NK cells overexpressed 1098 genes and 28 human microRNAs. Genes in the crosstalk between dendritic and NK cells and metabolic pathways were up-regulated in expanded NK cells, whereas genes in a number of immune function pathways were down-regulated. Among all the most up-regulated genes were the NK cell-activating receptor natural cytotoxicity triggering receptor 3, myxovirus restistance 1, lymphotoxin beta, and BCL2-associated X protein. Although some expanded NK-cell product variability was observed, perhaps related to patient factors, further studies on larger numbers of products will be needed to determine the impact of these differences on clinical outcomes.

TI Selection of CD8(+)PD-1(+) Lymphocytes in Fresh Human Melanomas Enriches for Tumor-reactive T Cells SO JOURNAL OF IMMUNOTHERAPY LA English DT Article DE PD-1; PD-L1; TIL; tumor immunity; melanoma; tumor digest; tumor microenvironment ID INDUCED EXPRESSION; PD-1; CANCER; THERAPY; ANTIGEN; ACTIVATION; IMMUNOTHERAPY; CARCINOMA; RECEPTOR; MEMBER AB CD8(+) tumor-infiltrating lymphocytes (TILs) in human melanomas express high levels of PD-1 and are functionally impaired. However, adoptive cell therapy using in vitro-expanded TIL can be a highly effective therapy for patients with advanced melanoma. This discrepancy led us to further analyze the CD8(+)PD-1(+) TILs. We found that the percentage of PD-1-expressing CD8(+) T cells was higher in the tumor digests that generate tumor-reactive TILs after in vitro culture in interleukin-2 (P=0.0007). Also sorted and expanded CD8(+)PD-1(+) T cells in tumor digests showed much higher tumor-specific interferon-gamma production compared with CD8(+) PD-1(-) T cells. These results suggested that tumor-specific CD8(+) T cells in melanoma tumor digests are largely PD-1(+), and this population can recover function after culturing in interleukin-2. PD-1 has been reported as an inhibitory receptor on T cells. We found that the in vitro functional suppression of cultured-TILs from native levels of PD-L1 expression on melanomas was minimal, and moreover expression level of PD-1 on CD8(+) tumor-specific TILs decreased during the culture. As a consequence, the PD-1 receptor can be a useful biomarker for enriching tumor-specific T cells from fresh melanomas.

TI Sex and Geographic Patterns of Human Herpesvirus 8 Infection in a Nationally Representative Population-Based Sample in Uganda SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article ID SARCOMA-ASSOCIATED HERPESVIRUS; SUB-SAHARAN AFRICA; KAPOSIS-SARCOMA; RISK-FACTORS; TRANSMISSION; SEROPREVALENCE; PREVALENCE; PARASITES; CANCER; ADULTS AB Background. Human herpesvirus 8 (HHV8), the infectious cause of Kaposi sarcoma, varies dramatically across Africa, suggesting that cofactors correlated with large-area geographic or environmental characteristics may influence risk of infection. Variation in HHV8 seropositivity across small-area regions within countries in Africa is unknown. We investigated this issue in Uganda, where Kaposi sarcoma distribution is uneven and well described. Methods. Archival samples from individuals aged 15-59 years randomly selected from a nationally representative 2004-2005 human immunodeficiency virus-AIDS serobehavioral survey were tested for HHV8 seropositivity with use of enzyme immunoassays based on synthetic peptides from the K8.1 and orf65 viral genes. Adjusted odds ratios and 95% confidence intervals (CIs) of association of HHV8 seropositivity with demographic risk factors were estimated. Results. Among 2681 individuals tested, HHV8 seropositivity was 55.4%. HHV8 seropositivity was lower in female than in male persons (adjusted odds ratio, 0.82 [95% CI, 0.69-0.97]) and increased 2.2% (95% CI, 1.0%-3.6%) in female persons and 1.2% (95% CI, 1.0%-2.3%) in male persons per year of age. HHV8 seropositivity was inversely associated with education (P = .01, for trend) and was elevated in the West Nile region, compared with the Central region (adjusted odds ratio, 1.49 [95% CI, 1.02-2.18]) but not with other regions. Conclusions. Our findings suggest that HHV8 seropositivity in Uganda may be influenced by cofactors correlated with small-area geography, age, sex, and education.

We report that patas monkeys share immunophenotypic features with natural hosts of SIV; that is, low levels of CD4(+) T cells and low CCR5 expression on CD4(+) T cells. In 1 patas monkey with undetectable levels of CD4(+) T cells, experimental exposure to SIVagm did not result in infection. The other experimentally infected patas monkeys showed an infection pattern similar to SIV infection in natural hosts. Thus, down-regulation of CD4 and CCR5 expression on CD4(+) T cells may effectively control human immunodeficiency virus acquisition and result in SIV extinction.

Although in some instances this may represent good fortune, cohorts of uninfected persons have been reported who are considered at high risk for infection. In these cohorts a variety of characteristics have been proposed as mediating protection, but to date only the 32-base pair deletion in the chemokine (C-C motif) receptor 5 gene, which results in complete failure of cell surface expression of this coreceptor, has been associated with high-level protection from HIV infection. With this in mind, there are probably many other factors that may individually or in combination provide some level of protection from acquisition of HIV infection. Because some of these factors are probably incompletely protective or inconsistently active, identifying them with confidence will be difficult. Nonetheless, clarifying the determinants of protection against HIV infection is a high priority that will require careful selection of high-risk uninfected cohorts, who should undergo targeted studies of plausible mediators and broad screening for unexpected determinants of protection.

LRRFIP2 positively regulates NFkB and macrophage cytokine production after lipopolysaccharide, but less is known about LRRFIP1. We hypothesized that LRRFIP1 could be more important in antiviral responses, as overexpression led to type I IFN production in a pilot study. The induction of type I IFNs occurred even in the absence of virus, but was enhanced by the presence of virus. Conversely, knockdown of LRRFIP1 compromised IFN expression. We found that LRRFIP1 was rapidly recruited to influenza-containing early endosomes in a p38-dependent fashion. This was specific for virus-containing endosomes as there was almost no colocalization of LRRFIP1 with early endosomes in the absence of virus. Further, LRRFIP1 was recruited to RNA-containing vesicles. Taken together, these data suggest that LRRFIP1 participates in cell responses to virus at early time points and is important for type I IFN induction.

The zebrafish (Danio rerio) has two ABCC6-related sequences. To study the function of abcc6 during zebrafish development, the mRNA expression levels were measured using RT-PCR and in situ hybridization. The abcc6a showed a relatively high level of expression at 5 days post-fertilization (d.p.f.) and the expression was specific to the Kupffer's vesicles. The abcc6b expression was evident at 6 hours post-fertilization (h.p.f.) and remained high up to 8 d.p.f., corresponding to embryonic kidney proximal tubules. Morpholinos were designed to both genes to prevent pre-mRNA splicing and block translation. Injection of the abcc6a morpholinos into 1-4 cell zebrafish embryos decreased gene expression by 54-81%, and induced a phenotype, pericardial edema and curled tail associated with death at around 8 d.p.f. Microinjecting zebrafish embryos with full-length mouse Abcc6 mRNA together with the morpholino completely rescued this phenotype. No phenotypic changes were observed when the abcc6b gene morpholino was injected into embryos with knockdown efficiency of 100%. These results suggest that abcc6a is an essential gene for normal zebrafish development and provide insight into the function of ABCC6, the gene mutated in PXE.

Thus, an efficacious vaccine should induce Th1 and Tc1 cells. Dendritic cells (DCs) pulsed with exogenous proteins primarily induce strong CD4-dependent immunity; induction of CD8 responses has proven to be difficult. We evaluated the immunogenicity of fusion proteins comprising the protein transduction domain of HIV-1 TAT and the Leishmania antigen LACK (Leishmania homolog of receptors for activated C kinase), as TAT-fusion proteins facilitate major histocompatibility complex class I-dependent antigen presentation. In vitro, TAT-LACK-pulsed DCs induced stronger proliferation of Leishmania-specific CD8(+) T cells compared with DCs incubated with LACK alone. Vaccination with TAT-LACK-pulsed DCs or fusion proteins plus adjuvant in vivo significantly improved disease outcome in Leishmania major-infected mice and was superior to vaccination with DCs treated with LACK alone. Vaccination with DC+TAT-LACK resulted in stronger proliferation of CD8(+) T cells when compared with immunization with DC+LACK. Upon depletion of CD4(+) or CD8(+) T cells, TAT-LACK-mediated protection was lost. TAT-LACK-pulsed IL-12p40-deficient DCs did not promote protection in vivo. In summary, these data show that TAT-fusion proteins are superior in activating Leishmania-specific Tc1 cells when compared with antigen alone and suggest that IL-12-dependent preferential induction of antigen-specific CD8(+) cells promotes significant protection against this important human pathogen.

Orai1/STIM1 is essential to MC SOCE, as shown in rat peritoneal MCs, the rat MC lines (RBL-2H3), or in Orai1 null embryo liver-derived, cultured MCs. However, minimal information exists about the role of other calcium channels expressed on these cells. Here, we demonstrate that the nonselective TRPC1 participates in Fc epsilon RI-mediated calcium entry in mouse BMMCs. We found that Fyn null MCs, which have an impaired degranulation response, expressed reduced levels of TRPC1, had normal depletion of intracellular calcium stores but an impaired calcium influx, and failed to depolymerize cortical F-actin (a key step for granule-plasma membrane fusion). Partial RNAi silencing of TRPC1 expression in WT MCs (to the level of Fyn null MCs) mimicked the Fyn null defect in calcium influx, cortical F-actin depolymerization, and MC degranulation. Ectopic expression of Fyn or TRPC1 in Fyn null MCs restored calcium responses and cortical F-actin depolymerization and increased MC degranulation. Together with our findings that expression of Orai1 is not altered in Fyn null MCs, our findings suggest that TRPC1 participates in calcium influx and other key events required for MC degranulation. This demonstrates that in addition to a role described previously for Orai1 in promoting MC degranulation, nonselective cation channels participate in promoting the exocytotic response. J. Leukoc.

Mutations in the PLA2G6 gene encoding this enzyme occur in patients with idiopathic neurodegeneration plus brain iron accumulation and dystoniaparkinsonism without iron accumulation, whereas mice lacking PLA2G6 show neurological dysfunction and neuropathology after 13 months. We hypothesized that brain DHA metabolism and signaling would be reduced in 4-month-old iPLA(2)beta-deficient mice without overt neuropathology. Saline or the cholinergic muscarinic M 1,3,5 receptor agonist arecoline (30 mg/kg) was administered to unanesthetized iPLA(2)beta(-/-), iPLA(2)beta(+/-), and iPLA(2)beta(+/+) mice, and [1-C-14]DHA was infused intravenously. DHA incorporation coefficients k* and rates J(in), representing DHA metabolism, were determined using quantitative autoradiography in 81 brain regions. iPLA(2)beta(-/-) or iPLA(2)beta(+/-) compared with iPLA(2)beta(+/+) mice showed widespread and significant baseline reductions in k* and J(in) for DHA. Arecoline increased both parameters in brain regions of iPLA(2)beta(+/+) mice but quantitatively less so in iPLA(2)beta(-/-) and iPLA(2)beta(+/-) mice. Consistent with iPLA(2)beta's reported ability to selectively hydrolyze DHA from phospholipid in vitro, iPLA(2)beta deficiency reduces brain DHA metabolism and signaling in vivo at baseline and following M 1,3,5 receptor activation. Positron emission tomography might be used to image disturbed brain DHA metabolism in patients with PLA2G6 mutations.-Basselin, M., A. O. Rosa, E. Ramadan, Y. Cheon, L. Chang, M. Chen, D.

TI Macrophage ABCA1 reduces MyD88-dependent Toll-like receptor trafficking to lipid rafts by reduction of lipid raft cholesterol SO JOURNAL OF LIPID RESEARCH LA English DT Article DE free cholesterol; cytokines; immunology; lipid droplets; lymphocytes; retinoids ID INNATE IMMUNE RECOGNITION; CASSETTE TRANSPORTER A1; TANGIER-DISEASE; ABCA1-DEFICIENT MACROPHAGES; PLASMA-MEMBRANE; APOA-I; ATHEROSCLEROSIS; ACTIVATION; EXPRESSION; ACCUMULATION AB We previously showed that macrophages from macrophage-specifi c ATP-binding cassette transporter A1 (ABCA1) knockout (Abca1(-M/-M)) mice had an enhanced proinflammatory response to the Toll-like receptor (TLR) 4 agonist, lipopolysaccharide (LPS), compared with wild-type (WT) mice. In the present study, we demonstrate a direct association between free cholesterol (FC), lipid raft content, and hyper-responsiveness of macrophages to LPS in WT mice. Abca1(-M/-M) macrophages were also hyper-responsive to specific agonists to TLR2, TLR7, and TLR9, but not TLR3, compared with WT macrophages. We hypothesized that ABCA1 regulates macrophage responsiveness to TLR agonists by modulation of lipid raft cholesterol and TLR mobilization to lipid rafts. We demonstrated that Abca1(-M/-M) vs. WT macrophages contained 23% more FC in isolated lipid rafts. Further, mass spectrometric analysis suggested raft phospholipid composition was unchanged. Although cell surface expression of TLR4 was similar between Abca1(-M/-M) and WT macrophages, significantly more TLR4 was distributed in membrane lipid rafts in Abca1(-M/-M) macrophages. Abca1(-M/-M) macrophages also exhibited increased trafficking of the predominantly intracellular TLR9 into lipid rafts in response to TLR9-specifi c agonist (CpG). Collectively, our data suggest that macrophage ABCA1 dampens inflammation by reducing MyD88-dependent TLRs trafficking to lipid rafts by selective reduction of FC content in lipid rafts.-Zhu, X., J.

TI Sodium inversion recovery MRI of the knee joint in vivo at 7T SO JOURNAL OF MAGNETIC RESONANCE LA English DT Article DE Osteoarthritis; Cartilage; Sodium; Magnetic resonance imaging; Inversion recovery; Adiabatic inversion ID BOVINE ARTICULAR-CARTILAGE; FIXED CHARGE-DENSITY; MAGNETIC-RESONANCE; ADIABATIC PULSES; HUMAN BRAIN; NA-23 MRI; NMR AB The loss of proteoglycans (PG) in the articular cartilage is an early signature of osteoarthritis (OA). The ensuing changes in the fixed charge density in the cartilage can be directly linked to sodium concentration via charge balance. Sodium ions in the knee joint appear in two pools: in the synovial fluids or joint effusion where the ions are in free motion and bound within the cartilage tissue where the Na(+) ions have a restricted motion. The ions in these two compartments have therefore different T(1) and T(2) relaxation times. The purpose of this study is to demonstrate the feasibility of a fluid-suppressed 3D ultrashort TE radial sodium sequence by implementing an inversion recovery (IR) preparation of the magnetization at 7T. This method could allow a more accurate and more sensitive quantification of loss of PG in patients with OA. It is shown that adiabatic pulses offer significantly improved performance in terms of robustness to B(1) and B(0) inhomogeneities when compared to the hard pulse sequence. Power deposition considerations further pose a limit to the RF inversion power, and we demonstrate in simulations and experiments how a practical compromise can be struck between clean suppression of fluid signals and power deposition levels. Two IR sequences with different types of inversion pulses (a rectangular pulse and an adiabatic pulse) were tested on a liquid phantom, ex vivo on a human knee cadaver and then in vivo on five healthy volunteers, with a (Nyquist) resolution of similar to 3.6 mm and a signal-to-noise ratio of similar to 30 in cartilage without IR and similar to 20 with IR. Due to specific absorption rate limitations, the total acquisition time was similar to 17 min for the 3D radial sequence without inversion or with the rectangular IR, and 24:30 min for the adiabatic IR sequence. It is shown that the adiabatic IR sequence generates a more uniform fluid suppression over the whole sample than the rectangular IR sequence. (C) 2010 Elsevier Inc. All rights reserved.

TI Bloodmeal Size and Spirochete Acquisition of Ornithodoros hermsi (Acari: Argasidae) During Feeding SO JOURNAL OF MEDICAL ENTOMOLOGY LA English DT Article DE Borrelia hermsii; relapsing fever; ticks; quantitative PCR ID SUBGENUS PERSICARGAS IXODOIDEA; RELAPSING FEVER; BORRELIA-BURGDORFERI; MAJOR SEROTYPES; MEAL WEIGHT; TICK; MOUBATA; GROWTH AB Ornithodoros hermsi Wheeler (Acari: Argasidae) is the vector of Borrelia hermsii, the primary cause of tick-borne relapsing fever in North America. This tick is one of the smallest Ornithodoros species involved with the biological transmission of spirochetes; yet, the amount of blood ingested while feeding is unknown. Therefore, we determined the amount of blood O. hermsi ingested during a bloodmeal to establish its potential for spirochete acquisition while feeding on an infected host. Ticks at different developmental stages were weighed before and after feeding and the volume of blood ingested was calculated. Females ingested the most blood, averaging approximate to 15 mu l per meal, but late-stage nymphs took in the most blood in proportion to unfed body weight. A cohort of nymphs was weighed three more times during the 48 h after feeding, which demonstrated that O. hermsi may have excreted coxal fluid ranging from 24 -36% of the bloodmeal weight. We also developed a quantitative polymerase chain reaction method to determine the number of spirochetes ingested and maintained within the ticks after feeding. The density of spirochetes in ticks having just engorged was slightly less than in the host's blood, hi the first 5 d after feeding, the number of spirochetes within the ticks declined from the number initially ingested but then remained constant through 15 d. These observations establish a basis for future studies to determine the minimum number of spirochetes required in the host's blood to allow O. hermsi to become persistently infected and transmit during subsequent bloodmeals.

A strain of Art. culicifacies isolated from its natural niche displayed complete refractoriness to P. vicar by melanotic encapsulation of ookinetes. Prophenoloxidases are key components of the phenoloxidase cascade that leads to recognition and melanization of invading organisms. We isolated and cloned prophenoloxidase-encoding acppo6 gene of An. culicifacies and analyzed its expression profile under various regimens of immune challenge. The aeppo6 was differentially expressed during various stages of larval development. The acppo6 transcription was also up-regulated in response to bacteria and Plasmodium vinckei petteri challenge. The transcript levels of the acppo6 gene were higher in naive adult refractory female mosquitoes as compared with female susceptible mosquitoes. Furthermore, the induction of acppo6 in the susceptible strain upon Plasmodium infection was negligible as compared with that of the refractory strain. The observation is suggestive of the role of acppo6 in effectuating a melanotic response in Plasmodium-incompetent naturally occurring refractory An. culicifacies strain.

The structures of the new compounds were established by interpretation of their spectroscopic data. All of the isolates were tested for cytotoxicity against HT-29 cells. The new silvestrol analogues, 1 and 2, were considerably less active as cytotoxic agents than silvestrol (7) and episilvestrol (5 '''-episilvestrol) (8) against this cell line, showing the importance of the configuration at C-2 ''' in mediating such activity within this compound class.

Ret appeared as 150- and 170-kDa bands on sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels and both forms were sensitive to peptide-N-glycosidase F. Western and immunocytochemical analyses revealed that the 150-kDa immature form of Ret accumulated in the Golgi apparatus upon treatment with vacuolar proton-ATPase inhibitors, whereas, the 170-kDa mature form of Ret was dramatically decreased. The result suggests that glycosylation of Ret during the conversion from immature forms to mature forms is pH sensitive, and is likely initiated in the acidic trans-Golgi apparatus. In contrast, glycosylation of nascent receptors to become immature receptors appeared to be pH insensitive, and are likely to take place in the endoplasmic reticulum. The immature form of Ret was present in the plasma membrane when the cells were treated with the vacuolar proton-ATPase inhibitors. In conclusion, the acidification of the Golgi apparatus is crucial for maturation of Ret but not indispensable for trafficking of receptors to the membrane.

Spectral responses in zebrafish horizontal cells include a tetraphasic response and a novel UV-dominated triphasic response. J Neurophysiol 104: 2407-2422, 2010. First published July 7, 2010; doi:10.1152/jn.00644.2009. Zebrafish are tetra-chromats with red (R, 570 nm), green (G, 480 nm), blue (B, 415 nm), and UV (U, 362 nm) cones. Although neurons in other cyprinid retinas are rich in color processing neural circuitry, spectral responses of individual neurons in zebrafish retina, a genetic model for vertebrate color vision, are yet to be studied. Using dye-filled sharp microelectrodes, horizontal cell voltage responses to light stimuli of different wavelengths and irradiances were recorded in a superfused eyecup. Spectral properties were assessed both qualitatively and quantitatively. Six spectral classes of horizontal cell were distinguished. Two monophasic response types (L1 and L2) hyperpolarized at all wavelengths. L1 sensitivities peaked at 493 nm, near the G cone absorbance maximum. Modeled spectra suggest equally weighted inputs from both R and G cones and, in addition, a "hidden opponency" from blue cones. These were classified as R-/G-/(b+). L2 sensitivities were maximal at 563 nm near the R cone absorbance peak; modeled spectra were dominated by R cones, with lesser G cone contributions. B and UV cone signals were small or absent. These are R-/g-. Four chromatic (C-type) horizontal cells were either depolarized (+) or hyperpolarized (-) depending on stimulus wavelength. These types are biphasic (R+/G-/B-) with peak excitation at 467 nm, between G and B cone absorbance peaks, UV triphasic (r-/G+/U-) with peak excitation at 362 nm similar to UV cones, and blue triphasic (r-/G+/B-/u-) and blue tetraphasic (r-/G+/B-/u+), with peak excitation at 409 and 411 nm, respectively, similar to B cones. UV triphasic and blue tetraphasic horizontal cell spectral responses are unique and were not anticipated in previous models of distal color circuitry in cyprinids.

Late-expiratory activity: emergence and interactions with the respiratory CPG. J Neurophysiol 104: 2713-2729, 2010. First published September 8, 2010; doi:10.1152/jn.00334.2010. The respiratory rhythm and motor pattern are hypothesized to be generated by a brain stem respiratory network with a rhythmogenic core consisting of neural populations interacting within and between the pre-Botzinger (pre-BotC) and Botzinger (BotC) complexes and controlled by drives from other brain stem compartments. Our previous large-scale computational model reproduced the behavior of this network under many different conditions but did not consider neural oscillations that were proposed to emerge within the retrotrapezoid nucleus/parafacial respiratory group (RTN/pFRG) and drive preinspiratory (or late-expiratory, late-E) discharges in the abdominal motor output. Here we extend the analysis of our previously published data and consider new data on the generation of abdominal late-E activity as the basis for extending our computational model. The extended model incorporates an additional late-E population in RTN/pFRG, representing a source of late-E oscillatory activity. In the proposed model, under normal metabolic conditions, this RTN/pFRG oscillator is inhibited by BotC/pre-BotC circuits, and the late-E oscillations can be released by either hypercapnia-evoked activation of RTN/pFRG or by hypoxia-dependent suppression of RTN/pFRG inhibition by BotC/pre-BotC. The proposed interactions between BotC/pre-BotC and RTN/pFRG allow the model to reproduce several experimentally observed behaviors, including quantal acceleration of abdominal late-E oscillations with progressive hypercapnia and quantal slowing of phrenic activity with progressive suppression of pre-BotC excitability, as well as to predict a release of late-E oscillations by disinhibition of RTN/pFRG under normal conditions. The extended model proposes mechanistic explanations for the emergence of RTN/pFRG oscillations and their interaction with the brain stem respiratory network.

In this study, we examined the rate and direction of microtubule polymerization in response to soluble nerve growth factor (NGF) and immobilized chondroitin sulfate proteoglycans (CSPGs) by expressing enhanced GFP-EB3 in rat pheochromocytoma (PC12) cells. GFP-EB3 comets were monitored in live cells using time-lapse epifluorescent microscopy. With an automated tracking system, the rate of microtubule polymerization was calculated as the frame-to-frame displacement of EB3 comets. Our results demonstrate that the rate of microtubule polymerization is increased following NGF treatment, whereas contact with CSPGs decreases microtubule polymerization rates. This reduction in microtubule polymerization rates was specifically localized to neurites in direct contact with CSPGs and not at noncontacting neurites. Additionally, we found an increase in the percentage of microtubules polymerizing in the retrograde direction in neurites at CSPG boundaries, with a concomitant decrease in the rate of retrograde microtubule polymerization. These results implicate localized changes in microtubule dynamics as an important component of the growth cone response to guidance cues. (c) 2010 Wiley-Liss, Inc.

Both Epo and Epo receptor (EpoR) are expressed in the brain and are up-regulated by hypoxia. Brain Epo signaling can stimulate neural cell survival and prevent neuron apoptosis. Neurons from EpoR null mice exhibit marked increased sensitivity to hypoxia. In endothelial cells, Epo has been shown to stimulate nitric oxide (NO) production, particularly at low pO(2). We found here that the EpoR expression on neural cells and Epo's neuroprotective effect were regulated by NO. Hypoxia increased NO production as well as EpoR expression, and inhibition of NOS activity reduced the proportion of EpoR-expressing neurons induced at low pO(2). Conversely, addition of NO donor to cultures grown under normoxia induced EpoR. Similarly, NO donor increased EpoR promoter activity in a reporter gene assay, suggesting that NO regulates EpoR at the transcription level. Preincubation of neurons with NO results in induction of EpoR, which gives rise to protection against hypoxia even in the absence of exogenous Epo, although at high concentration NO is toxic. These data provide evidence of a role for NO in Epo activity in brain and suggest links between NO production, EpoR expression, and Epo signaling in neuroprotection.

Early assessment of tumor response is required to manage patients in terms of quality of life versus intensive chemotherapy. Although imaging with radiolabeled annexin V has been intensively investigated, it is still not sufficiently mature for clinical application. This article will summarize various alternative imaging techniques for visualization of phosphatidylserine externalization, activity of caspases, and mitochondrial membrane potential. Such imaging studies will promote the identification of novel molecular targets and the development of highly specific apoptosis-detecting imaging probes with potential clinical applications. It is highly possible that quantitative imaging of apoptosis will greatly improve clinical decision making in apoptosis-related diseases.

However, fully optimized PET agents for determining CXCR4 expression by tumor cells in vivo are not yet available. This study aims to develop a stable, F-18-labeled peptide that enables in vivo quantification of CXCR4 in cancer. Methods: 4-F-benzoyl-TN14003 (4-F-T140), a short peptide antagonist of CXCR4 with 1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl protecting groups on the E-amino groups of the lysine residues, was labeled with F-18-fluoride via N-succinimidyl-4-F-18-fluorobenzoate conjugation, followed by deprotection to give 4-F-18-T140 that was exclusively labeled on the alpha-amine at the N terminus. Cell binding, migration, biodistribution, and small-animal PET studies of 4-F-18-T140 were performed. Results: 4-F-T140 was radiolabeled by coupling with N-succinimidyl-4-F-18-fluorobenzoate, with an overall decay-corrected radiochemical yield of 15% +/- 5% calculated from the start of synthesis. The mean measured specific activity (+/- SD) was 7 +/- 2 GBq/mu mol (0.19 +/- 0.05 Ci/mu mol), and radiochemical purity was greater than 99%. 4-F-18-T140 was found to bind specifically to red blood cells in vitro and in vivo. The binding of 4-F-18-T140 to red blood cells was blocked with a small amount of cold 4-F-T140, which led to higher uptake of 4-F-18-T140 by Chinese hamster ovarian (CHO)-CXCR4 tumors. Biodistribution experiments at 3 h after injection with the addition of 10 mu g of cold 4-F-T140 showed a 3.03 +/- 0.31 percentage injected dose per gram uptake in CHO-CXCR4 tumors, with a tumor-to-blood ratio of 27.1 +/- 8.7 and a tumor-to-muscle ratio of 21.6 +/- 7.1. PET studies demonstrated clear visualization of CXCR4-transfected, but not CXCR4-negative, CHO tumors. Conclusion: 4-F-18-T140 can be used as a PET tracer to image tumor expression of CXCR4, with a high tumor-to-background ratio. The knowledge of whether tumors express or do not express CXCR4 might be beneficial in determining appropriate treatment and monitoring.

Background Teamwork has been associated with a higher level of job satisfaction but few studies have focused on the acute care inpatient hospital nursing team. Methods This was a cross-sectional study with a sample of 3675 nursing staff from five hospitals and 80 patient care units. Participants completed the Nursing Teamwork Survey (NTS). Results Participants' levels of job satisfaction with current position and satisfaction with occupation were both higher when they rated their teamwork higher (P < 0.001) and perceived their staffing as adequate more often (P < 0.001). Type of unit influenced both satisfaction variables (P < 0.05). Additionally, education, gender and job title influenced satisfaction with occupation (P < 0.05) but not with current position. Conclusions Results of this present study demonstrate that within nursing teams on acute care patient units, a higher level of teamwork and perceptions of adequate staffing leads to greater job satisfaction with current position and occupation. Implications for Nursing Management Findings suggest that efforts to improve teamwork and ensure adequate staffing in acute care settings would have a major impact on staff satisfaction.

Topics included the following: 1) options for dealing with assay fluctuations in serum 25(OH)D in the NHANES conducted between 1988 and 2006; 2) approaches for transitioning between the RIA used in the NHANES between 1988 and 2006 to the liquid chromatography tandem MS (LC-MS/MS) measurement procedure to be used in NHANES 2007 and later; 31 approaches for integrating the recently available standard reference material for vitamin D in human serum (SAM 972) from the National Institute of Standards and Technology (NIST) into the NHANES; 41 questions regarding whether the C-3 epimer of 25-hydroxyvitamin D3 [3-epi-25(OH)D3] should be measured in NHANES 2007 and later; and 5) identification of research and educational needs. The roundtable experts agreed that the NHANES data needed to be adjusted to control for assay fluctuations and offered several options for addressing this issue. The experts suggested that the LC-MS/MS measurement procedure developed by NIST could serve as a higher order reference measurement procedure. They noted the need for a commutability study for the recently released NIST SRM 972 across a range of measurement procedures. They suggested that federal agencies and professional organizations work with manufacturers to improve the quality and comparability of measurement procedures across all laboratories. The experts noted the preliminary nature of the evidence of the 3-epi-25(OH)D3 but felt that it should be measured in 2007 NHANES and later. J. Nutr. 140: 2030S-2045S, 2010.

Methods: Standardized incidence ratios (SIRs) and relative standardized ratios were calculated. Results: A significant excess of prostate cancer was seen for private and commercial applicators (SIR = 1.19, 95% CI 1.14, 1.25 and SIR = 1.28, 95% CI = 1.00, 1.61, respectively). Excesses were observed for lip cancer (SIR = 1.97, 95% CI = 1.02, 3.44) and multiple myeloma (SIR = 1.42, 95% CI = 1.00, 1.95) among private applicators from North Carolina and for marginal zone lymphoma among Iowa spouses (SIR = 2.34, 95% CI = 1.21, 4.09). Conclusions: Although lower rates of smoking and increased physical activity probably contribute to the lower overall cancer incidence, agricultural exposures including pesticides, viruses, bacteria, sunlight, and other chemicals may increase risks for specific cancer sites.

Methods Data were obtained from a national sample of 7,475 US adolescents in grades 6 through 10 in the 2005/2006 Health Behavior in School-Aged Children (HBSC) study. Latent class analyses (LCA) were conducted on victimization by physical, verbal, social exclusion, spreading rumors, and cyber bullying. Results Three latent classes were identified, including an all-types victims class (9.7% of males and 6.2% of females), a verbal/relational victims class (28.1% of males and 35.1% of females), and a nonvictim class (62.2% of males and 58.7% of females). Males were more likely to be all-type victims. There was a graded relationship between the three latent classes and level of depression, frequency of medically attended injuries, and medicine use, especially among females. Conclusions Increased co-occurrence of victimization types put adolescents at greater risks for poorer physical and psychological outcomes.

Study design A total of 6499 ELBW infants (401-1000 g) surviving to 36 weeks postmenstrual age (PMA) were included in this retrospective study. Unadjusted comparisons were performed between infants with (n = 414) and without (n = 6085) clinical seizures during the initial hospitalization. Using multivariate logistic regression modeling, we examined the independent association of seizures with late death (after 36 weeks PMA) or NDI after controlling for multiple demographic, perinatal, and neonatal variables. Results Infants with clinical seizures had a greater proportion of neonatal morbidities associated with poor outcome, including severe intraventricular hemorrhage, sepsis, meningitis, and cystic periventricular leukomalacia (all P < .01). Survivors were more likely to have NDI or moderate-severe cerebral palsy at 18 to 22 months corrected age (both P < .01). After adjusting for multiple confounders, clinical seizures remained significantly associated with late death or NDI (odds ratio, 3.15; 95% CI, 2.37-4.19). Conclusion ELBW infants with clinical seizures are at increased risk for adverse neurodevelopmental outcome, independent of multiple confounding factors. (J Pediatr 2010; 157: 720-5).

Methods: Myometrium was obtained from women with (n=19) and without labor (n=20). Illumina (R) HumanHT-12 microarrays were utilized. Moderated t-tests and false discovery rate adjustment of P-values were applied. Real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) was performed for a select set of differentially expressed genes in a separate set of samples. Enzyme-linked immunosorbent assay and Western blot were utilized to confirm differential protein production in a third sample set. Results: 1) Four hundred and seventy-one genes were differentially expressed; 2) gene ontology analysis indicated enrichment of 103 biological processes and 18 molecular functions including: a) inflammatory response; b) cytokine activity; and c) chemokine activity; 3) systems biology pathway analysis using signaling pathway impact analysis indicated six significant pathways: a) cytokine-cytokine receptor interaction; b) Jak-STAT signaling; and c) complement and coagulation cascades; d) NOD-like receptor signaling pathway; e) systemic lupus erythematosus; and f) chemokine signaling pathway; 4) qRT-PCR confirmed over-expression of prostaglandin-endoperoxide synthase-2, heparin binding epidermal growth factor (EGF)-like growth factor, chemokine C-C motif ligand 2 (CCL2/MCP1), leukocyte immunoglobulin-like receptor, subfamily A member 5, interleukin (IL)-8, IL-6, chemokine C-X-C motif ligand 6 (CXCL6/GCP2), nuclear factor of kappa light chain gene enhancer in B-cells inhibitor zeta, suppressor of cytokine signaling 3 (SOCS3) and decreased expression of FK506 binding-protein 5 and aldehyde dehydrogenase in labor; 5) IL-6, CXCL6, CCL2 and SOCS3 protein expression was significantly higher in the term labor group compared to the term not in labor group. Conclusions: Myometrium of women in spontaneous labor at term is characterized by a stereotypic gene expression pattern consistent with over-expression of the inflammatory response and leukocyte chemotaxis. Differential gene expression identified with microarray was confirmed with qRT-PCR using an independent set of samples. This study represents an unbiased description of the biological processes involved in spontaneous labor at term based on transcriptomics.

Women trained to have a more positive math attitude exhibited increased math motivation (Study 1). This effect was not observed for men but was magnified among women when negative stereotypes were either primed subtly (Study 2) or indirectly reinforced (Study 3). Although attitudes had no effect on working memory capacity, women retrained to associate their gender with being good at math exhibited increased working memory capacity (Studies 3 and 4), which in turn mediated increased math performance (Study 4) in a stereotype-threatening context. Results suggest that although positive attitudes can motivate stigmatized individuals to engage with threatening domains, stereotypes need to be retrained to give them the cognitive capacity critical for success. Implications for interventions to reduce stereotype threat are discussed. C1 [Forbes, Chad E.] Univ Arizona, Dept Psychol, Tucson, AZ 85721 USA.

The aim of this study was to conduct a head-to-head comparison between two NO-ASAs possessing different NO donor groups, an organic nitrate [3-nitrooxyphenyl acetylsalicylate (NO-ASA; NCX-4016)] and an N-diazeniumdiolate [NONO-ASA, O-2-(acetylsalicyloxymethyl)-1-(pyrrolidin-1-yl)diazen-1-ium-1,2-diolate (NONO-ASA; CVM-01)], as antiulcerogenic, analgesic, anti-inflammatory, and antipyretic agents. All drugs were administered orally at equimolar doses. For antiulcerogenic study, 6 h after administration, the number and size of hemorrhagic lesions in stomachs from euthanized animals were counted. Tissue samples were frozen for prostaglandin E-2 (PGE(2)), superoxide dismutase (SOD), and malondialdehyde determination. For anti-inflammatory study, 1 h after drug administration, the volume of carrageenan-induced rat paw edemas was measured for 6 h. For antipyretic study, 1 h after dosing, fever was induced by intraperitoneal LPS, and body core temperatures measured for 5 h. For analgesic study, time-dependent analgesic effect of prodrugs was evaluated by carrageenan-induced hyperalgesia. Drugs were administered 30 min after carrageenan. NO-ASA and NONO-ASA were equipotent as analgesic and anti-inflammatory agents but were better than aspirin. Despite a drastic reduction of PGE(2) in stomach tissue, both prodrugs were devoid of gastric side effects. Lipid peroxidation induced by aspirin was higher than that observed by prodrugs. SOD activity induced by both prodrugs was similar, but approximately 2-fold higher than that induced by aspirin. CVM-01 is as effective as NCX-4016 in anti-inflammatory, analgesic, and antipyretic assays in vivo, and it showed an equivalent safety profile in the stomach. These results underscore the use of N-diazeniumdiolate moieties in drug design.

Serotonergic systems also modulate nociception, and serotonin uptake inhibitors may be useful as adjuncts to enhance analgesic effects and/or attenuate undesirable effects of mu agonists. This study examined the effects of the serotonin uptake inhibitor clomipramine on behavioral effects produced in rhesus monkeys by mu agonists with varying efficacy at mu receptors (nalbuphine < morphine < methadone). Clomipramine and each mu agonist were studied alone and in fixed-proportion mixtures in assays of schedule-controlled responding, thermal nociception, and capsaicin-induced thermal allodynia. In the assay of schedule-controlled responding, all mu agonists dose-dependently decreased response rates. Clomipramine was inactive alone and did not alter the effects of mu agonists. In the assay of thermal nociception, all mu agonists produced dose-dependent antinociception. Clomipramine was inactive alone but produced a proportion-dependent enhancement of the antinociceptive effects of nalbuphine > morphine > methadone. In the assay of capsaicin-induced allodynia, nalbuphine produced dose-dependent antiallodynia. Clomipramine alone was inactive, but as in the assay of thermal nociception, it produced a proportion-dependent enhancement in the effects of nalbuphine. These findings suggest that serotonin uptake inhibitors can selectively enhance the antinociceptive effects of mu agonists in nonhuman primates. These effects of serotonin uptake inhibitors may depend on the proportion of the serotonin uptake inhibitor and the efficacy of the mu agonist. The greatest enhancement was observed with intermediate proportions of clomipramine in combination with the low-efficacy mu agonist nalbuphine. C1 [Banks, Matthew L.; Negus, S.

This disorder exhibits several phenotypic traits including dysmorphia and mental retardation with a broad range of severity. There are few proven treatment options. That most commonly used is a high cholesterol diet that seems to enhance the quality of life and improve behavioral characteristics of patients, although these positive effects are controversial. The goal of our study was to investigate the possibility of restoring DHCR7 activity by gene transfer. We constructed an adeno-associated virus (MV) vector containing the DHCR7 gene. After we infused this vector into affected mice, the introduced DHCR7 gene could be identified in liver, mRNA was expressed and a functional enzyme was produced. Evidence of functionality came from the ability to partially normalize the serum ratio of 7DHC/C in treated animals, apparently by increasing cholesterol production with concomitant decrease in 7DHC precursor. By 5 weeks after treatment the mean ratio (for 7 animals) had fallen to 0.05 while the ratio for untreated littermate controls had risen to 0.14. This provides proof of principle that gene transfer can ameliorate the genetic defect causing SLOS and provides a new experimental tool for studying the pathogenesis of this disease. If effective in humans, it might also offer a possible alternative to exogenous cholesterol therapy. However, it would not offer a complete cure for the disorder as many of the negative implications of defective synthesis are already established during prenatal development. (C) 2010 Elsevier Ltd.

TI Development of an image analysis screen for estrogen receptor alpha (ER alpha) ligands through measurement of nuclear translocation dynamics SO JOURNAL OF STEROID BIOCHEMISTRY AND MOLECULAR BIOLOGY LA English DT Article DE Estrogen receptor; High-content screening; Cell-based assay; Nuclear translocation; Cytotoxicity ID HEALTHY POSTMENOPAUSAL WOMEN; BREAST EPITHELIAL-CELLS; NONALCOHOLIC STEATOHEPATITIS; PLUS PROGESTIN; TAMOXIFEN; CANCER; TRIAL; CARCINOGENS; KIDNEY; LIVER AB We have developed a robust high-content assay to screen for novel estrogen receptor alpha (ER alpha) agonists and antagonists by quantitation of cytoplasmic to nuclear translocation of an estrogen receptor chimera in 384-well plates. The screen utilizes a green fluorescent protein tagged-glucocorticoid/estrogen receptor (GFP-GRER) chimera which consisted of the N-terminus of the glucocorticoid receptor fused to the human ER ligand binding domain. The GFP-GRER exhibited cytoplasmic localization in the absence of ER alpha ligands, and translocated to the nucleus in response to stimulation with ER alpha agonists or antagonists. The BD Pathway 435 imaging system was used for image acquisition, analysis of translocation dynamics, and cytotoxicity measurements. The assay was validated with known ER alpha agonists and antagonists, and the Library of Pharmacologically Active Compounds (LOPAC 1280). Additionally, screening of crude natural product extracts demonstrated the robustness of the assay, and the ability to quantitate the effects of toxicity on nuclear translocation dynamics. The GFP-GRER nuclear translocation assay was very robust, with z' values >0.7, CVs <5%, and has been validated with known ER ligands, and inclusion of cytotoxicity filters will facilitate screening of natural product extracts. This assay has been developed for future primary screening of synthetic, pure natural products, and natural product extracts libraries available at the National Cancer Institute at Frederick.

CC-5079, a small molecule inhibitor of tubulin polymerization and phosphodiesterase-4 activity, was evaluated for antiangiogenic and antitumor activities. Materials and Methods. First, CC-5079 in vitro activity on human umbilical vein endothelial cells (HU-VECs), fibroblasts, and MC38 were evaluated by proliferation, migration, and invasion assays. Second, CC-5079 effect on microvessel formation was evaluated ex vivo by chick chorioallantoic membrane (CAM), rat aortic rings assays, and with directed in vivo angiogenesis assay (DIVAA). Third, CC-5079 antitumor effect was determined in treatment of C57BL/6 mice with MC38 tumors. Finally, CC-5079 modulation of MKP1 in HUVECs, human fibroblast, and MC38 were determined by RNA isolation for qRT-PCR. Results. At the 0.1 mu M concentration CC-5079 significantly inhibited HUVEC, fibroblast, and MC38 proliferation and migration (all P < 0.001). At the 0.1 mu M concentration, CC-5079 also inhibited HUVEC invasion (P < 0.05) but not fibroblast. In the CAM and rat aortic ring assays, CC-5079 at 0.1 mu M inhibited microvessel formation (P < 0.05). By DIVAA, CC-5079 at 1 mg/kg/d continuous delivered inhibited microvessel formation (P < 0.05). Intraperitoneal CC-5079 was well tolerated and inhibited the growth of subcutaneous MC38 at 100 mg/kg/d (P < 0.01). By qRT-PCR, CC-5079 stimulated MKP1 expression in HUVEC and fibroblast. Conclusion. CC-5079 demonstrated stimulation of MKP1 antiangiogenic, and antitumor properties. Published by Elsevier Inc.

Objective: Our purpose was to evaluate progression of skin lesion:; in patients with Proteus syndrome. Methods: Skin findings were documented in 36 patients with Proteus syndrome. Progression of skin lesions in 16 of these patients was assessed by comparing photographs obtained on repeated visits for an average total duration of 53 months. Results: The skin lesion most characteristic of Proteus syndrome, the cerebriform connective tissue nevus, showed progression in 13 children but not in 3 adults. The cerebriform connective tissue nevus progressed by expansion into previously uninvolved skin, increased thickness, and development of new lesions. Lipomas increased in size, number, or both in 8 of 10 children with lipomas. In contrast, epidermal nevi and Vascular malformations generally did not spread or increase in number. Limitations: Only 3 adults with Proteus syndrome were evaluated longitudinally. Conclusion: The cerebriform connective tissue nevus in Proteus syndrome grows throughout childhood but tends to remain stable in adulthood. (J Am Acad Dermatol 2010;63:799-804.)

DESIGN: Prospective observational study of the causes and course of physical disability. SETTING: Twelve contiguous ZIP code areas in Baltimore, Maryland. PARTICIPANTS: Three hundred seven community-dwelling women aged 70 to 79 at study baseline. MEASUREMENTS: The outcome was all-cause mortality (1994-2009); predictors included up to seven repeated measurements of handgrip, knee extension, and hip flexion strength, with a median follow-up time of 10 years. Demographic factors, body mass index, smoking status, number of chronic diseases, depressive symptoms, physical activity, interleukin-6, and albumin were assessed at baseline and included as confounders. The associations between declining muscle strength and mortality were assessed using a joint longitudinal and survival model. RESULTS: Grip and hip strength declined an average of 1.10 and 1.31 kg/year between age 70 and 75 and 0.50 and 0.39 kg/year thereafter, respectively; knee strength declined at a constant rate of 0.57 kg/year. Faster rates of decline in grip and hip strength, but not knee strength, independently predicted mortality after accounting for baseline levels and potential confounders (hazard ratio (HR) = 51.33, 95% confidence interval (95%) CI = 1.06-1.67, HR = 1.14, 95% CI = 0.91-1.41, and 2.62, 95% CI = 1.43-4.78 for every 0.5 standard deviation increase in rate of decline in grip, knee, and hip strength, respectively). CONCLUSION: Monitoring the rate of decline in grip and hip flexion strength in addition to absolute levels may greatly improve the identification of women most at risk of dying.

DESIGN: Cohort study. SETTING: Clinic examinations in Pittsburgh, Pennsylvania, or Memphis, Tennessee. PARTICIPANTS: Well-functioning adults aged 70 to 79 who participated in the Health, Aging and Body Composition Study. MEASUREMENTS: Hospitalizations were reported at annual clinic visits and in semiannual phone interviews. In the event of death or reported hospitalization, hospitalizations were adjudicated according to medical record review. Dual X-ray absorptiometry (DXA) assessments of total, lean, and fat mass were conducted in six annual examinations, and measures of knee extensor strength were conducted in two annual examinations. RESULTS: DXA assessments followed 2,309 hospitalizations. In men and women, hospitalization in the previous year was associated with greater declines in total mass (- 0.76 and -0.81 kg, respectively), fat mass (-0.41 and -0.54 kg), and lean mass (-0.33 and -0.25 kg) (P < .001 for all) than in nonhospitalized participants, after adjustment for demographics and baseline values. Hospitalization was associated with strength declines in men (-4.02 Nm, P = .046) but not in women. Relationships were similar after adjusting for health behaviors and chronic conditions, although the association between hospitalization and strength was attenuated. Associations increased with number of days hospitalized; hospitalizations totaling 8 days or more in the previous year were associated with significantly greater loss of total, lean, and fat mass and loss of strength in both sexes than in nonhospitalized participants. CONCLUSION: Hospitalization is associated with significant changes in body composition and strength in older persons. These effects appear particularly important in persons hospitalized for 8 or more days per year. J Am Geriatr Soc 58:2085-2091, 2010.

SO JOURNAL OF THE AMERICAN MEDICAL DIRECTORS ASSOCIATION LA English DT Article DE Aging; disability; impairments ID PHYSICAL PERFORMANCE; OLDER-ADULTS; PRECLINICAL DISABILITY; WOMENS HEALTH; MOBILITY DISABILITY; RISK; DEPENDENCE; VALIDITY; DECLINE; DISEASE AB Introduction: The relationship between self-reported function and objective measures of physiological function among disabled older women was analyzed to determine the validity of self-reported function, and to identify the hierarchy of self-reported task difficulty most associated with loss of independence as a basis to inform treatment progress goals. Methods: A randomly selected population of older women with moderate to high disability was selected from community-dwelling women 65 to 101 years old from the Women's Health and Aging Study I baseline evaluation (n = 987). Cross-sectional analyses evaluated the association of self-reported function with objective physiological impairment measures. Results: The results indicated that (1) disabled older women self-reported a broad range of physical function levels; (2) self-reported function correlated closely with objective measures of physiological impairments; (3) "preclinical disability," as measured by self-reported modification of task performance in the absence of perceived difficulty, has validity even in a disabled population, and identifies a group intermediate between those who are high functioning in a task and those with difficulty; and (4) there is an apparent gradation in physiological impairment measures with reported loss of functional independence. Conclusion: These findings suggest the validity of self-report functional disability measures and the potential to use these measures to identify already-disabled older adults at risk for further functional degradation and potential targets for intervention.

Design Problem list terms and their usage frequencies were collected from large healthcare institutions. Measurement The pattern of usage of the terms was analyzed. The local terms were mapped to the Unified Medical Language System (UMLS). Based on the mapped UMLS concepts, the degree of overlap between the PLTs was analyzed. Results Six institutions submitted 76 237 terms and their usage frequencies in 14 million patients. The distribution of usage was highly skewed. On average, 21% of unique terms already covered 95% of usage. The most frequently used 14 395 terms, representing the union of terms that covered 95% of usage in each institution, were exhaustively mapped to the UMLS. 13 261 terms were successfully mapped to 6776 UMLS concepts. Less frequently used terms were generally less 'mappable' to the UMLS. The mean pairwise overlap of the PLTs was only 21% (median 19%). Concepts that were shared among institutions were used eight times more often than concepts unique to one institution. A SNOMED Problem List Subset of frequently used problem list concepts was identified. Conclusions Most of the frequently used problem list terms could be found in standard terminologies. The overlap between existing PLTs was low. The use of the SNOMED Problem List Subset will save developmental effort, reduce variability of PLTs, and enhance interoperability of problem list data.

TI Using global unique identifiers to link autism collections SO JOURNAL OF THE AMERICAN MEDICAL INFORMATICS ASSOCIATION LA English DT Article ID PERSONAL IDENTIFIERS AB Objective To propose a centralized method for generating global unique identifiers to link collections of research data and specimens. Design The work is a collaboration between the Simons Foundation Autism Research Initiative and the National Database for Autism Research. The system is implemented as a web service: an investigator inputs identifying information about a participant into a client application and sends encrypted information to a server application, which returns a generated global unique identifier. The authors evaluated the system using a volume test of one million simulated individuals and a field test on 2000 families (over 8000 individual participants) in an autism study. Measurements Inverse probability of hash codes; rate of false identity of two individuals; rate of false split of single individual; percentage of subjects for which identifying information could be collected; percentage of hash codes generated successfully. Results Large-volume simulation generated no false splits or false identity. Field testing in the Simons Foundation Autism Research Initiative Simplex Collection produced identifiers for 96% of children in the study and 77% of parents. On average, four out of five hash codes per subject were generated perfectly (only one perfect hash is required for subsequent matching). Discussion The system must achieve balance among the competing goals of distinguishing individuals, collecting accurate information for matching, and protecting confidentiality. Considerable effort is required to obtain approval from institutional review boards, obtain consent from participants, and to achieve compliance from sites during a multicenter study. Conclusion Generic unique identifiers have the potential to link collections of research data, augment the amount and types of data available for individuals, support detection of overlap between collections, and facilitate replication of research findings.

Bodenreider, Olivier TI Comparing and evaluating terminology services application programming interfaces: RxNav, UMLSKS and LexBIG SO JOURNAL OF THE AMERICAN MEDICAL INFORMATICS ASSOCIATION LA English DT Article ID MEDICAL LANGUAGE SYSTEM AB To facilitate the integration of terminologies into applications, various terminology services application programming interfaces (API) have been developed in the recent past. In this study, three publicly available terminology services API, RxNav, UMLSKS and LexBIG, are compared and functionally evaluated with respect to the retrieval of information from one biomedical terminology, RxNorm, to which all three services provide access. A list of queries is established covering a wide spectrum of terminology services functionalities such as finding RxNorm concepts by their name, or navigating different types of relationships. Test data were generated from the RxNorm dataset to evaluate the implementation of the functionalities in the three API. The results revealed issues with various aspects of the API implementation (eg, handling of obsolete terms by LexBIG) and documentation (eg, navigational paths used in RxNav) that were subsequently addressed by the development teams of the three API investigated. Knowledge about such discrepancies helps inform the choice of an API for a given use case.

TI Prolonged Drug Selection of Breast Cancer Cells and Enrichment of Cancer Stem Cell Characteristics SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Article ID EPITHELIAL-MESENCHYMAL TRANSITION; ALDEHYDE DEHYDROGENASE-ACTIVITY; MULTIDRUG-RESISTANCE; CARCINOMA-CELLS; P-GLYCOPROTEIN; GLUCOSYLCERAMIDE SYNTHASE; LUNG-CANCER; NUDE-MICE; IN-VITRO; EXPRESSION AB Background Cancer stem cells are presumed to have virtually unlimited proliferative and self-renewal abilities and to be highly resistant to chemotherapy, a feature that is associated with overexpression of ATP-binding cassette transporters. We investigated whether prolonged continuous selection of cells for drug resistance enriches cultures for cancer stem-like cells. Methods Cancer stem cells were defined as CD44+/CD24- cells that could self-renew (ie, generate cells with the tumorigenic CD44+/CCD24- phenotype), differentiate, invade, and form tumors in vivo. We used doxorubicin-selected MCF-7/ADR cells, weakly tumorigenic parental MCF-7 cells, and MCF-7/MDR, an MCF-7 subline with forced expression of ABCB1 protein. Cells were examined for cell surface markers and side-population fractions by microarray and flow cytometry, with in vitro invasion assays, and for ability to form mammospheres. Xenograft tumors were generated in mice to examine tumorigenicity (n = 52). The mRNA expression of multidrug resistance genes was examined in putative cancer stem cells and pathway analysis of statistically significantly differentially expressed genes was performed. All statistical tests were two-sided. Results Pathway analysis showed that MCF-7/ADR cells express mRNAs from ABCB1 and other genes also found in breast cancer stem cells (eg, CD44, TGFB1, and SNAI1). MCF-7/ADR cells were highly invasive, formed mammospheres, and were tumorigenic in mice. In contrast to parental MCF-7 cells, more than 30% of MCF-7/ADR cells had a CD44+/CCD24- phenotype, could self-renew, and differentiate (ie, produce CD44+/CCD24- and CD44+/CD24+ cells) and overexpressed various multidrug resistance-linked genes (including ABCB1, CCNE1, and MMP9). MCF-7/ADR cells were statistically significantly more invasive in Matrigel than parental MCF-7 cells (MCF-7 cells = 0.82 cell per field and MCF-7/ADR = 7.51 cells per field, difference = 6.69 cells per field, 95% confidence interval = 4.82 to 8.55 cells per field, P < .001). No enrichment in the CD44+/CCD24- or CD133+ population was detected in MCF-7/MDR. Conclusion The cell population with cancer stem cell characteristics increased after prolonged continuous selection for doxorubicin resistance.

Methods Study participants were women aged 18-25 years at enrollment in the control group of the ongoing National Cancer Institute-sponsored, community-based, randomized HPV16/18 Costa Rica Vaccine Trial. At enrollment, 2813 participants were negative for cervical HPV16 DNA and 2950 for HPV18 DNA. Women were interviewed regarding sociodemographic data and medical and health history. Medical and pelvic examinations were conducted for all consenting sexually experienced women. Serum samples taken at enrollment were tested for total HPV16/18 antibodies with a polyclonal enzyme-linked immunosorbent assay, and cervical specimens were tested for type-specific HPV DNA over 4 years of follow-up. Using Poisson regression, we compared rate ratios of newly detected cervical HPV16 or HPV18 infection among homologous HPV-seropositive and HPV-seronegative women, adjusting for age, education, marital status, lifetime number of sexual partners, and smoking. Results There were 231 newly detected HPV16 infections during 5886 person-years among HPV16-seronegative women compared with 12 newly detected HPV16 infections during 581 person-years among HPV16-seropositive women with the highest HPV16 sero-levels. There were 136 newly detected HPV18 infections during 6352 person-years among HPV18-seronegative women compared with six new infections detected during 675 person-years among HPV18 seropositives with the highest sero-levels. After controlling for risk factors associated with newly detected HPV infection, having high HPV16 antibody titer at enrollment was associated with a reduced risk of subsequent HPV16 infection (women in the highest tertile of HPV16 antibody titers, adjusted rate ratio = 0.50, 95% confidence interval = 0.26 to 0.86 vs HPV16-seronegative women). Similarly, having high HPV18 antibody titer at enrollment was associated with a reduced risk of subsequent HPV18 infection (women in the highest tertile of HPV18 antibody titers, adjusted rate ratio = 0.36, 95% confidence interval = 0.14 to 0.76 vs HPV18-seronegative women). Conclusion In this study population, having high antibody levels against HPV16 and HPV18 following natural infection was associated with reduced risk of subsequent HPV16 and HPV18 infections.

TI Cancer Pharmacogenomics and Pharmacoepidemiology: Setting a Research Agenda to Accelerate Translation SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Editorial Material ID RECEIVING ADJUVANT TAMOXIFEN; BREAST-CANCER; COLORECTAL-CANCER; LUNG-CANCER; THERAPY; CYP2D6; SURVIVAL; CYP2D6-ASTERISK-10; ASSOCIATION; MUTATIONS AB Recent advances in genomic research have demonstrated a substantial role for genomic factors in predicting response to cancer therapies. Researchers in the fields of cancer pharmacogenomics and pharmacoepidemiology seek to understand why individuals respond differently to drug therapy, in terms of both adverse effects and treatment efficacy. To identify research priorities as well as the resources and infrastructure needed to advance these fields, the National Cancer Institute (NCI) sponsored a workshop titled "Cancer Pharmacogenomics: Setting a Research Agenda to Accelerate Translation" on July 21, 2009, in Bethesda, MD. In this commentary, we summarize and discuss five science-based recommendations and four infrastructure-based recommendations that were identified as a result of discussions held during this workshop. Key recommendations include 1) supporting the routine collection of germline and tumor biospecimens in NCI-sponsored clinical trials and in some observational and population-based studies; 2) incorporating pharmacogenomic markers into clinical trials; 3) addressing the ethical, legal, social, and biospecimen- and data-sharing implications of pharmacogenomic and pharmacoepidemiologic research; and 4) establishing partnerships across NCI, with other federal agencies, and with industry. Together, these recommendations will facilitate the discovery and validation of clinical, sociodemographic, lifestyle, and genomic markers related to cancer treatment response and adverse events, and they will improve both the speed and efficiency by which new pharmacogenomic and pharmacoepidemiologic information is translated into clinical practice.

Standard of care for these patients is systemic chemotherapy with a median survival of 6 months and a 5-year survival of only 2%. Our aim was to critically evaluate the published data on pulmonary resection for metastatic gastric cancer (MGC) and to analyze the potential rationale for surgical management to determine which patients may benefit from this approach. Methods: The Pubmed and SCOPUS databases were queried for all studies reporting on pulmonary resections for MGC. All available clinicopathologic data were analyzed. Results: Twenty-one studies from 1975 to 2008 reported 48 pulmonary resections in 43 patients including five repeat resections and four extrapulmonary metastasectomies. Eighty-two percent (34/43) of patients had solitary lesions with a median size of 24 mm (4-90 mm). Median time from gastrectomy to pulmonary resection was 35 months (0-120 months). At a median follow-up of 23 months, 15 of 43 (35%) patients were alive without disease, and two patients died without disease. Median survival was 29 months (3-84 months) after pulmonary metastasectomy and 65 months (5-180 months) after gastrectomy. Fifty-six percent (24/43) of patients had another recurrence at a median of 12 months (range: 6-48 months) after resection including 30% (13/43) of patients with pulmonary recurrences. Overall 5-year survival was 33%. Conclusions: Pulmonary metastasectomy for MGC can potentially result in long-term survival in a highly selected group of patients and should be considered for those who present with small, isolated lesions after a prolonged disease-free interval.

Congenital anomalies are the leading cause of infant mortality in the United States, and congenital heart defects (CHDs) are the most common type of birth defects. Recently, 4-dimensional ultrasonography (4DUS) with spatiotemporal image correlation (STIC) has been introduced for fetal echocardiography. Accumulating evidence indicates that 4DUS with STIC may facilitate the examination of the fetal heart. Our objectives were to determine the accuracy of 4DUS for the diagnosis of CHDs and the agreement among centers. Methods. This study included 7 centers with expertise in 4D fetal echocardiography. Fetuses with and without confirmed heart defects were scanned between 18 and 26 weeks, and their volume data sets were uploaded onto a centralized file transfer protocol server. Intercenter agreement was determined using a kappa statistic for multiple raters. Results. Ninety volume data sets were randomly selected for blinded analysis. Overall, the median (range) sensitivity, specificity, positive and negative predictive values, and false-positive and -negative rates for the identification of fetuses with CHDs were 93% (77%-100%), 96% (84%-100%), 96% (83%-100%), 93% (79%-100%), 4.8% (2.7%-25%), and 6.8% (5%-22%), respectively. The most frequent CHDs were conotruncal anomalies (36%). There was excellent intercenter agreement (kappa = 0.97). Conclusions. (1) Four-dimensional volume data sets can be remotely acquired and accurately interpreted by different centers. (2) Among centers with technical expertise, 4DUS is an accurate and reliable method for fetal echocardiography.

In this study we evaluate the recurrence and functional outcomes in a von Hippel-Lindau syndrome cohort treated for pheochromocytoma with partial adrenalectomy with a followup of at least 5 years. Materials and Methods: We reviewed the records of patients with von Hippel-Lindau syndrome treated with partial adrenalectomy for pheochromocytoma at the National Cancer Institute. Demographic, germline mutation status, surgical indication, oncologic and functional outcome data were collected. Local recurrence was defined as radiographic evidence of recurrent tumor on the ipsilateral side of partial adrenalectomy. Patients were considered steroid dependent if they required steroids at most recent followup. Results: A total of 36 partial adrenalectomies for pheochromocytoma were performed in 26 patients with von Hippel-Lindau syndrome between September 1995 and December 2003. Of these cases 23 were performed open and 13 were performed laparoscopically. Prior surgical history was obtained for all patients. At a median followup of 9.25 years (range 5 to 46) metastatic pheochromocytoma had not developed in any patients. In 3 patients (11%) there were 5 local recurrences treated with surgical extirpation or active surveillance. All recurrences were asymptomatic and detected by radiographic imaging on followup. In addition, 3 of 26 patients (11%) subsequently required partial adrenalectomy for pheochromocytoma on the contralateral adrenal gland. In the entire cohort only 3 patients became steroid dependent (11%). Conclusions: Outcomes of partial adrenalectomy in patients with von Hippel-Lindau syndrome with pheochromocytoma are encouraging at long-term followup and should be recommended as a primary surgical approach whenever possible. Adrenal sparing surgery can obviate the need for steroid replacement in the majority of patients. Local recurrence rates appear to be infrequent and can be managed successfully with subsequent observation or intervention.

A3F has been shown to have strong antiviral activity in transient-expression studies, and together with A3G, it is considered the most potent cytidine deaminase targeting HIV. Previous analyses suggested that the antiviral properties of A3F can be dissociated from its catalytic deaminase activity. We were able to confirm the deaminase-independent antiviral activity of exogenously expressed A3F; however, we also noted that exogenous expression was associated with very high A3F mRNA and protein levels. In analogy to our previous study of A3G, we produced stable HeLa cell lines constitutively expressing wild-type or deaminase-defective A3F at levels that were more in line with the levels of endogenous A3F in H9 cells. A3F expressed in stable HeLa cells was packaged into Vif-deficient viral particles with an efficiency similar to that of A3G and was properly targeted to the viral nucleoprotein complex. Surprisingly, however, neither wild-type nor deaminase-defective A3F inhibited HIV-1 infectivity. These results imply that the antiviral activity of endogenous A3F is negligible compared to that of A3G. C1 [Strebel, Klaus] NIAID, Viral Biochem Sect, Mol Microbiol Lab, NIH, Bethesda, MD 20892 USA.

TI Neuropeptide Y Has a Protective Role during Murine Retrovirus-Induced Neurological Disease SO JOURNAL OF VIROLOGY LA English DT Article ID CENTRAL-NERVOUS-SYSTEM; VIRUS-INFECTION; BRAIN DISEASE; IMMUNE-SYSTEM; RECEPTORS; MICE; PROTEIN; NEUROPATHOGENESIS; SEIZURES; CONTRIBUTE AB Viral infections in the central nervous system (CNS) can lead to neurological disease either directly by infection of neurons or indirectly through activation of glial cells and production of neurotoxic molecules. Understanding the effects of virus-mediated insults on neuronal responses and neurotrophic support is important in elucidating the underlying mechanisms of viral diseases of the CNS. In the current study, we examined the expression of neurotrophin-and neurotransmitter-related genes during infection of mice with neurovirulent polytropic retrovirus. In this model, virus-induced neuropathogenesis is indirect, as the virus predominantly infects macrophages and microglia and does not productively infect neurons or astrocytes. Virus infection is associated with glial cell activation and the production of proinflammatory cytokines in the CNS. In the current study, we identified increased expression of neuropeptide Y (NPY), a pleiotropic growth factor which can regulate both immune cells and neuronal cells, as a correlate with neurovirulent virus infection. Increased levels of Npy mRNA were consistently associated with neurological disease in multiple strains of mice and were induced only by neurovirulent, not avirulent, virus infection. NPY protein expression was primarily detected in neurons near areas of virus-infected cells. Interestingly, mice deficient in NPY developed neurological disease at a faster rate than wild-type mice, indicating a protective role for NPY. Analysis of NPY-deficient mice indicated that NPY may have multiple mechanisms by which it influences virus-induced neurological disease, including regulating the entry of virus-infected cells into the CNS.

Studies of the host response, including microarray analyses, have relied on the close relationship between these two primate species: chimpanzee samples are commonly tested with human-based reagents. In this study, the host responses to two dissimilar viruses, hepatitis E virus (HEV) and hepatitis C virus (HCV), were compared in multiple experimentally infected chimpanzees. Affymetrix U133 + 2.0 human microarray chips were used to assess the entire transcriptome in serial liver biopsies obtained over the course of the infections. Respecting the limitations of microarray probes designed for human target transcripts to effectively assay chimpanzee transcripts, we conducted probe-level analysis of the microarray data in conjunction with a custom mapping of the probe sequences to the most recent human and chimpanzee genome sequences. Time points for statistical comparison were chosen based on independently measured viremia levels. Regardless of the viral infection, the alignment of differentially expressed genes to the human genome sequence resulted in a larger number of genes being identified when compared with alignment to the chimpanzee genome sequence. This probably reflects the lesser refinement of gene annotation for chimpanzees. In general, the two viruses demonstrated very distinct temporal changes in host response genes, although both RNA viruses induced genes that were involved in many of the same biological systems, including interferon-induced genes. The host response to HCV infection was more robust in the magnitude and number of differentially expressed genes compared to HEV infection.

However, a number of studies have shown a subsequent risk of cancer development or aberrant clonal growths due to vector insertion near or within proto-oncogenes. Recent advances in the sequencing technology enable high-throughput clonality analysis via vector integration site (VIS) sequencing, which is particularly useful for studying complex polyclonal hematopoietic progenitor/stem cell (HPSC) repopulation. However, clonal repopulation analysis using the current methods is typically semiquantitative. Here, we present a novel system and standards for accurate clonality analysis using 454 pyrosequencing. We developed a bidirectional VIS PCR method to improve VIS detection by concurrently analyzing both the 5' and the 3' vector-host junctions and optimized the conditions for the quantitative VIS sequencing. The assay was validated by quantifying the relative frequencies of hundreds of repopulating HPSC clones in a nonhuman primate. The reliability and sensitivity of the assay were assessed using clone-specific real-time PCR. The majority of tested clones showed a strong correlation between the two methods. This assay permits high-throughput and sensitive assessment of clonal populations and hence will be useful for a broad range of gene therapy, stem cell, and cancer research applications.

To date, research on IFN antagonism by hantaviruses is limited and has focused on only a subset of the numerous recognized hantavirus species. The host IFN response has two phases, an initiation phase, resulting in the induction of alpha/beta IFN (IFN-alpha/beta), and an amplification phase, whereby IFN-alpha/beta signals through the Jak/STAT pathway, resulting in the establishment of the cellular antiviral state. We examined interactions between these critical host responses and the New World hantaviruses. We observed delayed cellular responses in both Andes virus (ANDV)- and Sin Nombre virus (SNV)-infected A549 and Huh7-TLR3 cells. We found that IFN-beta induction is inhibited by coexpression of ANDV nucleocapsid protein (NP) and glycoprotein precursor (GPC) and is robustly inhibited by SNV GPC alone. Downstream amplification by Jak/STAT signaling is also inhibited by SNV GPC and by either NP or GPC of ANDV. Therefore, ANDV- and SNV-encoded proteins have the potential for inhibiting both IFN-beta induction and signaling, with SNV exhibiting the more potent antagonism ability. Herein we identify ANDV NP, a previously unrecognized inhibitor of Jak/STAT signaling, and show that IFN antagonism by ANDV relies on expression of both the glycoproteins and NP, whereas the glycoproteins appear to be sufficient for antagonism by SNV. These data suggest that IFN antagonism strategies by hantaviruses are quite variable, even between species with similar disease phenotypes, and may help to better elucidate species-specific pathogenesis.

TI Virulence-Associated Substitution D222G in the Hemagglutinin of 2009 Pandemic Influenza A(H1N1) Virus Affects Receptor Binding SO JOURNAL OF VIROLOGY LA English DT Article ID SINGLE AMINO-ACID; LOWER RESPIRATORY-TRACT; A H1N1 VIRUS; MOLECULAR-BASIS; SEVERE DISEASE; H5N1 VIRUSES; HUMAN AIRWAY; HONG-KONG; HUMANS; TRANSMISSION AB The clinical impact of the 2009 pandemic influenza A(H1N1) virus (pdmH1N1) has been relatively low. However, amino acid substitution D222G in the hemagglutinin of pdmH1N1 has been associated with cases of severe disease and fatalities. D222G was introduced in a prototype pdmH1N1 by reverse genetics, and the effect on virus receptor binding, replication, antigenic properties, and pathogenesis and transmission in animal models was investigated. pdmH1N1 with D222G caused ocular disease in mice without further indications of enhanced virulence in mice and ferrets. pdmH1N1 with D222G retained transmissibility via aerosols or respiratory droplets in ferrets and guinea pigs. The virus displayed changes in attachment to human respiratory tissues in vitro, in particular increased binding to macrophages and type II pneumocytes in the alveoli and to tracheal and bronchial submucosal glands. Virus attachment studies further indicated that pdmH1N1 with D222G acquired dual receptor specificity for complex alpha 2,3- and alpha 2,6-linked sialic acids. Molecular dynamics modeling of the hemagglutinin structure provided an explanation for the retention of alpha 2,6 binding. Altered receptor specificity of the virus with D222G thus affected interaction with cells of the human lower respiratory tract, possibly explaining the observed association with enhanced disease in humans.

TI Quantifying Antigenic Relationships among the Lyssaviruses SO JOURNAL OF VIROLOGY LA English DT Article ID RABIES VIRUS GLYCOPROTEIN; LAGOS-BAT-VIRUS; A H3N2 VIRUSES; DUVENHAGE VIRUS; PHYLOGENETIC-RELATIONSHIPS; GENETIC EVOLUTION; CROSS-PROTECTION; INFLUENZA; DYNAMICS; VACCINES AB All lyssaviruses cause fatal encephalitis in mammals. There is sufficient antigenic variation within the genus to cause variable vaccine efficacy, but this variation is difficult to characterize quantitatively: sequence analysis cannot yet provide detailed antigenic information, and antigenic neutralization data have been refractory to high-resolution robust interpretation. Here, we address these issues by using state-of-the-art antigenic analyses to generate a high-resolution antigenic map of a global panel of 25 lyssaviruses. We compared the calculated antigenic distances with viral glycoprotein ectodomain sequence data. Although 67% of antigenic variation was predictable from the glycoprotein amino acid sequence, there are in some cases substantial differences between genetic and antigenic distances, thus highlighting the risk of inferring antigenic relationships solely from sequence data at this time. These differences included epidemiologically important antigenic differences between vaccine strains and wild-type rabies viruses. Further, we quantitatively assessed the antigenic relationships measured by using rabbit, mouse, and human sera, validating the use of nonhuman experimental animals as a model for determining antigenic variation in humans. The use of passive immune globulin is a crucial component of rabies postexposure prophylaxis, and here we also show that it is possible to predict the reactivity of immune globulin against divergent lyssaviruses.

The reassortant H7N7 NL/03 ca vaccine virus was temperature sensitive and attenuated in mice, ferrets, and African green monkeys (AGMs). Intranasal (i.n.) administration of a single dose of the H7N7 NL/03 ca vaccine virus fully protected mice from lethal challenge with homologous and heterologous H7 viruses from Eurasian and North American lineages. Two doses of the H7N7 NL/03 ca vaccine induced neutralizing antibodies in serum and provided complete protection from pulmonary replication of homologous and heterologous wild-type H7 challenge viruses in mice and ferrets. One dose of the H7N7 NL/03 ca vaccine elicited an antibody response in one of three AGMs that was completely protected from pulmonary replication of the homologous wild-type H7 challenge virus. The contribution of CD8(+) and/or CD4(+) T cells to the vaccine-induced protection of mice was evaluated by T-cell depletion; T lymphocytes were not essential for the vaccine-induced protection from lethal challenge with H7 wt viruses. Additionally, passively transferred neutralizing antibody induced by the H7N7 NL/03 ca virus protected mice from lethality following challenge with H7 wt viruses. The safety, immunogenicity, and efficacy of the H7N7 NL/03 ca vaccine virus in mice, ferrets, and AGMs support the evaluation of this vaccine virus in phase I clinical trials.

We conducted selection using a mixture of 8 highly multi-protease inhibitor (PI)-resistant, DRV-susceptible clinical HIV-1 variants (HIV-1(MIX)) containing 9 to 14 PI resistance-associated amino acid substitutions in protease. HIV-1MIX became highly resistant to DRV, with a 50% effective concentration (EC50) similar to 333-fold greater than that against HIV-1(NL4-3). HIV-1(MIX) at passage 51 (HIV-1(MIXP51)) replicated well in the presence of 5 mu M DRV and contained 14 mutations. HIV-1(MIXP51) was highly resistant to amprenavir, indinavir, nelfinavir, ritonavir, lopinavir, and atazanavir and moderately resistant to saquinavir and tipranavir. HIV-1(MIXP51) had a resemblance with HIV-1(C) of the HIV-1(MIX) population, and selection using HIV-1(C) was also performed; however, its DRV resistance acquisition was substantially delayed. The H219Q and I223V substitutions in Gag, lacking in HIV-1(CP51), likely contributed to conferring a replication advantage on HIV-1(MIXP51) by reducing intravirion cyclophilin A content. HIV-1(MIXP51) apparently acquired the substitutions from another HIV-1 strain(s) of HIV-1(MIX) through possible homologous recombination. The present data suggest that the use of multiple drug-resistant HIV-1 isolates is of utility in selecting drug-resistant variants and that DRV would not easily permit HIV-1 to develop significant resistance; however, HIV-1 can develop high levels of DRV resistance when a variety of PI-resistant HIV-1 strains are generated, as seen in patients experiencing sequential PI failure, and ensuing homologous recombination takes place. HIV-1(MIXP51) should be useful in elucidating the mechanisms of HIV-1 resistance to DRV and related agents.

We screened rodents and other mammals for sequence variation in the Xpr1 receptor for the mouse xenotropic or polytropic mouse leukemia viruses (X-MLVs or P-MLVs, respectively) of the gammaretrovirus family and for susceptibility to mouse-derived X/P-MLVs and to XMRV (xenotropic murine leukemia virus-related virus), an X-MLV-like virus isolated from humans with prostate cancer and chronic fatigue syndrome. We identified multiple distinct susceptibility phenotypes; these include the four known Xpr1 variants in Mus and a novel fifth Xpr1 gene found in Mus molossinus and Mus musculus. We describe the geographic and species distribution of the Mus Xpr1 variants but failed to find the X-MLV-restrictive laboratory mouse allele in any wild mouse. We used mutagenesis and phylogenetic analysis to evaluate the functional contributions made by constrained, variable, and deleted residues. Rodent Xpr1 is under positive selection, indicating a history of host-pathogen conflicts; several codons under selection have known roles in virus entry. All non-Mus mammals are susceptible to mouse X-MLVs, but some restrict other members of the X/P-MLV family, and the resistance of hamster and gerbil cells to XMRV indicates that XMRV has unique receptor requirements. We show that the hypervariable fourth extracellular XPR1 loop (ECL4) contains three evolutionarily constrained residues that do not contribute to receptor function, we identify two novel residues important for virus entry (I579 and T583), and we describe a unique pattern of ECL4 variation in the three virus-restrictive Xpr1 variants found in MLV-infected house mice; these mice carry different deletions in ECL4, suggesting either that these sites or loop size affects receptor function.

TI Reduction of Immune Activation with Chloroquine Therapy during Chronic HIV Infection SO JOURNAL OF VIROLOGY LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; T-CELL-ACTIVATION; LYMPHOCYTE-ACTIVATION; HYDROXYCHLOROQUINE; CD4(+); CD38; ZIDOVUDINE AB Increased levels of activated T cells are a hallmark of the chronic stage of human immunodeficiency virus (HIV) infection and are highly correlated with HIV disease progression. We evaluated chloroquine (CQ) as a potential therapy to reduce immune activation during HIV infection. We found that the frequency of CD38(+) HLA-DR(+) CD8 T cells, as well as Ki-67 expression in CD8 and CD4 T cells, was significantly reduced during CQ treatment. Our data indicate that treatment with CQ reduces systemic T-cell immune activation and, thus, that its use may be beneficial for certain groups of HIV-infected individuals.

TI Effects of Testosterone Administration on Nocturnal Cortisol Secretion in Healthy Older Men SO JOURNALS OF GERONTOLOGY SERIES A-BIOLOGICAL SCIENCES AND MEDICAL SCIENCES LA English DT Article DE Aging; Testosterone; Cortisol ID PITUITARY-ADRENAL AXIS; RANDOMIZED CONTROLLED-TRIAL; SEX-DIFFERENCES; GROWTH-HORMONE; DEHYDROEPIANDROSTERONE SECRETION; PSYCHOSOCIAL STRESS; PLASMA-CORTISOL; STEROID-HORMONE; AGED WOMEN; GENDER AB In animal studies, testosterone decreases, whereas estrogen increases, cortisol production. In one clinical study, short-term testosterone replacement attenuated corticotrophin-releasing hormone-stimulated cortisol secretion during leuprolide-induced hypogonadism in young men. The effects of longer term testosterone treatment on spontaneous cortisol secretion in younger or older men are unknown. In a randomized, double-masked placebo-controlled study, we assessed the effects of testosterone supplementation (100 mg intramuscular every 2 week) for 26 weeks on nocturnal cortisol secretory dynamics in healthy older men. Testosterone administration increased early morning serum concentrations of free testosterone by 34%, decreased sex hormone-binding globulin by 20%, and did not alter early morning concentrations of cortisol-binding globulin or cortisol compared with placebo treatment. Testosterone did not significantly alter nocturnal mean and integrated cortisol concentrations, cortisol burst frequency, mass/burst, basal secretion, pulsatile cortisol production rate, pattern regularity, or approximate entropy. We conclude that low-dose testosterone supplementation for 26 weeks does not affect spontaneous nocturnal cortisol secretion in healthy older men.

Because it is inexpensive and is not classified as a controlled substance by the US federal government, the authors wanted to evaluate its applicability as a practical and effective analgesic in male Sprague Dawley rats. They measured the efficacy of four dosages (4, 12.5, 25 or 50 mg tramadol per kg body weight) and three routes of administration (per os (p.o.) in a flavored gelatin cube, subcutaneous (s.c.) or intraperitoneal (i.p.)) using the hot-plate test and the tail-flick test, which were carried out 1 week apart. Rats that were dosed p.o. were given flavored gelatin cubes without tramadol on the 2 d before testing to help them become acclimated to the gelatin, in an effort to increase the likelihood that they would consume the gelatin on the testing day. Results from the hot-plate and tail-flick tests for rats that were given tramadol p.o. were similar before and after administration, regardless of tramadol dosage, suggesting that this route of administration was not effective. The s.c. route of administration was effective at dosages of 25 mg and 50 mg tramadol per kg body weight, although these dosages also resulted in sedation and skin lesions. The i.p. route of administration was also effective at dosages of 12.5 mg, 25 mg and 50 mg tramadol per kg body weight, though sedation was observed at dosages of 25 mg and 50 mg per kg body weight. Intraperitoneal administration of 12.5 mg tramadol per kg body weight had no notable side effects, and the authors plan to further study this dosage and route of administration in a rodent surgical model of pain.

Cg-Prkdc(scid) IL2rg(tmlWjl)/SzJ (NOD-severe combined immune deficient (scid) IL2rg(-/-)) mouse strain. Intravenous transplantation of 2 of 2 ALL cell lines and 9 of 14 primary ALL cases generated leukemia-like proliferations in recipient mice by 1-7 months after transplant. Leukemias were retransplantable, and the immunophenotypes, gene rearrangements and expression profiles were identical or similar to those of the original primary samples. NOD-scid mice transplanted with the same primary samples developed similar leukemias with only a slightly longer latency than did NOD-scid-IL2Rg(-/-) mice. In this highly sensitive NOD-scid-IL2Rg(-/-) -based assay, 1-100 unsorted primary human ALL cells from five of five tested patients, four of whom eventually experienced leukemia relapse, generated leukemias in recipient mice. This very high frequency of LSCs suggests that a hierarchical LSC model is not valuable for poor-outcome ALL.

Recent studies have shown that MM is preceded in virtually all cases by a premalignant state called monoclonal gammopathy of undetermined significance (MGUS). This review focuses on non-IgM MGUS and its progression to MM. Although certain clinical markers of MGUS progression have been identified, it currently is not possible to accurately determine individual risk of progression. This review focuses on the various biologic and molecular markers that could be used to determine the risk of MM progression. A better understanding of the pathogenesis will allow us to define the biological high-risk precursor disease and, ultimately, to develop early intervention strategies designed to delay and prevent full-blown MM.= 3 MET.min(-1) for >= 10 min (moderate-to vigorous-intensity PA (MVPA)) and >= 6 MET.min(-1) for >= 10 min (vigorous-intensity PA (VPA)). Self-reported PA was also assessed with a questionnaire. Accelerometry and self-reported PA data were compared across categories of BMI, sex, race, age, fitness, diabetes medication usage, and history of cardiovascular disease. Results: Self-reported PA was lower at higher levels of BMI, was higher in males, was lowest for African-American/black, and was positively associated with fitness. Multivariate analyses for accelerometer-measured MVPA and VPA showed that more PA bouts per day, minutes per bout, METs per minute, and MET-minutes were associated with higher fitness. For MVPA, bouts per day were higher in men, and METs per minute were higher in women. For VPA, bouts per day was positively associated with increasing age and differed by race/ethnicity. METs per minute were significantly lower at higher levels of BMI and in women. Diabetes medication usage and history of cardiovascular disease were not associated with patterns of PA examined. Conclusions: Results provide information on factors that contribute to PA patterns in adults with T2DM when PA is assessed using both objective and subjective measures. These data may inform interventions to improve PA in adults with T2DM. C1 [Jakicic, John M.] Univ Pittsburgh, Dept Hlth & Phys Act, Phys Act & Weight Management Res Ctr, Pittsburgh, PA 15260 USA.

Methods: With the use of data on women participating in the Medical Research Council National Survey of Health and Development who have been followed up from birth in March 1946 (n = 962), relationships between menopausal transition status and self-reported sleep difficulty were assessed annually in women between ages 48 and 54 years. Results: Menopausal transition status was related to severe self-reported sleep difficulty. The odds of reporting severe self-reported sleep difficulty were increased approximately by 2- to 3.5-fold (95% CI ranges from 1.08-3.27 to 1.99-6.04) for women in most menopausal transition statuses compared with women who remained premenopausal. After adjustment for current psychological, vasomotor, and somatic symptoms and waking frequently at night to use the toilet, only women who had a hysterectomy remained at an increased risk for moderate sleep difficulty. Conclusions: The modest relationship between menopausal transition status and moderate sleep difficulty may be related to greater variation in individual definitions of moderate difficulty. Attention to the level of sleep difficulty in this group of women will assist in the decision to address current health symptoms versus sleep itself. Women without prior health problems may experience severe self-reported sleeping difficulty during the menopausal transition and require tailored care from health professionals.

Methods: Participants were a subset of women aged 50 to 59 years with a history of hysterectomy who were enrolled in the Women's Health Initiative (WHI) estrogen-alone clinical trial and underwent a CT scan of the chest at the end of the trial to determine CAC. Participants provided information about VMS (hot flashes and/or night sweats), as well as HT use, on self-administered questionnaires at trial baseline. Results: The sample consisted of 918 women with a mean (SD) age of 55.1 (2.8) years at WHI randomization and 64.8 (2.9) years at CAC ascertainment. The prevalence of a CAC score higher than 0 was 46%, whereas the prevalence of a CAC score of 10 or higher and higher than 100 was 39% and 19%, respectively. At randomization, 77% reported a history of any VMS at any time before or at enrollment in the WHI, whereas 20% reported any VMS present only at enrollment. Compared with those without a history of any VMS and after adjustment for potential confounders, a history of any VMS at any time up to and including WHI enrollment was associated with significantly reduced odds for CAC higher than 0 (odds ratio, 0.66; 95% CI, 0.45-0.98). Moreover, as duration of HT increased, the inverse association between any VMS and CAC moved toward the null. Conclusions: A history of any VMS was significantly associated with reduced odds for CAC independent of traditional cardiovascular disease risk factors and other relevant covariates. This association seems to be influenced by duration of HT. C1 [Allison, Matthew A.] Univ Calif San Diego, La Jolla, CA 92093 USA.

Here, we identify APH_0032 as an Anaplasma-derived protein that associates with the A. phagocytophilum-occupied vacuolar membrane (AVM). APH_0032 is a 66.1 kDa acidic protein that electrophoretically migrates with an apparent molecular weight of 130 kDa. It contains a predicted transmembrane domain and tandemly arranged direct repeats that comprise 46% of the protein. APH_0032 is undetectable on Anaplasma organisms bound to the surfaces of HL-60 cells, but is detected on the AVM and surfaces of intravacuolar bacteria beginning 24 h post-infection. APH_0032 localizes to the AVM in HL-60, THP-1, HMEC-1, and ISE6 cells. APH_0032, along with APH_1387, which encodes a confirmed AVM protein, is transcribed during A. phagocytophilum infection of tick salivary glands and murine neutrophils. APH_0032 localizes to the AVM in neutrophils recovered from infected mice. The Legionella pneumophila Dot/IcM type IV secretion system (T4SS) can heterologously secrete a CyaA-tagged version of the A. phagocytophilum VirB/D T4SS effector, AnkA, but fails to secrete CyaA-tagged APH_0032 or APH_1387. These data confirm APH_0032 as an Anaplasma-derived AVM protein and hint that neither it nor APH_1387 are T4SS effectors. (C) 2010 Elsevier Ltd. All rights reserved.

Decreasing the levels of cellular polyamines stabilizes JunD mRNA without affecting its transcription, but the exact mechanism whereby polyamines regulate JunD mRNA degradation has not been elucidated. RNA-binding proteins HuR and AUF1 associate with labile mRNAs bearing AU-rich elements located in the 3' untranslated regions (3'-UTRs) and modulate their stability. Here, we show that JunD mRNA is a target of HuR and AUF1 and that polyamines modulate JunD mRNA degradation by altering the competitive binding of HuR and AUF1 to the JunD 3'-UTR. The depletion of cellular polyamines enhanced HuR binding to JunD mRNA and decreased the levels of JunD transcript associated with AUF1, thus stabilizing JunD mRNA. The silencing of HuR increased AUF1 binding to the JunD mRNA, decreased the abundance of HuR-JunD mRNA complexes, rendered the JunD mRNA unstable, and prevented increases in JunD mRNA and protein in polyamine-deficient cells. Conversely, increasing the cellular polyamines repressed JunD mRNA interaction with HuR and enhanced its association with AUF1, resulting in an inhibition of JunD expression. These results indicate that polyamines modulate the stability of JunD mRNA in intestinal epithelial cells through HuR and AUF1 and provide new insight into the molecular functions of cellular polyamines.

TI An Upstream Open Reading Frame and the Context of the Two AUG Codons Affect the Abundance of Mitochondrial and Nuclear RNase H1 SO MOLECULAR AND CELLULAR BIOLOGY LA English DT Article AB RNase H1 in mammalian cells is present in nuclei and mitochondria. Its absence in mitochondria results in embryonic lethality due to the failure to amplify mitochondrial DNA (mtDNA). Dual localization to mitochondria and nuclei results from differential translation initiation at two in-frame AUGs (M1 and M27) of a single mRNA. Here we show that expression levels of the two isoforms depend on the efficiency of translation initiation at each AUG codon and on the presence of a short upstream open reading frame (uORF) resulting in the mitochondrial isoform being about 10% as abundant as the nuclear form. Translation initiation at the M1 AUG is restricted by the uORF, while expression of the nuclear isoform requires reinitiation of ribosomes at the M27 AUG after termination of uORF translation or new initiation by ribosomes skipping the uORF and the M1 AUG. Such translational organization of RNase H1 allows tight control of expression of RNase H1 in mitochondria, where its excess or absence can lead to cell death, without affecting the expression of the nuclear RNase H1.

TI The beta/Gcd7 Subunit of Eukaryotic Translation Initiation Factor 2B (eIF2B), a Guanine Nucleotide Exchange Factor, Is Crucial for Binding eIF2 In Vivo SO MOLECULAR AND CELLULAR BIOLOGY LA English DT Article AB Eukaryotic translation initiation factor 2B (eIF2B) is the guanine nucleotide exchange factor (GEF) for eukaryotic translation initiation factor 2, which stimulates formation of the eIF2-GTP-Met-tRNA(i)(Met) ternary complex (TC) in a manner inhibited by phosphorylated eIF2 [eIF2(alpha P)]. While eIF2B contains five subunits, the epsilon/Gcd6 subunit is sufficient for GEF activity in vitro. The delta/Gcd2 and beta/Gcd7 subunits function with alpha/Gcn3 in the eIF2B regulatory subcomplex that mediates tight, inhibitory binding of eIF2(alpha P)-GDP, but the essential functions of delta/Gcd2 and beta/Gcd7 are not well understood. We show that the depletion of wild-type beta/Gcd7, three lethal beta/Gcd7 amino acid substitutions, and a synthetically lethal combination of substitutions in beta/Gcd7 and eIF2 alpha all impair eIF2 binding to eIF2B without reducing epsilon/Gcd6 abundance in the native eIF2B-eIF2 holo-complex. Additionally, beta/Gcd7 mutations that impair eIF2B function display extensive allele-specific interactions with mutations in the S1 domain of eIF2 alpha (harboring the phosphorylation site), which binds to eIF2B directly. Consistent with this, beta/Gcd7 can overcome the toxicity of eIF2(alpha P) and rescue native eIF2B function when overexpressed with delta/Gcd2 or gamma/Gcd1. In aggregate, these findings provide compelling evidence that beta/Gcd7 is crucial for binding of substrate by eIF2B in vivo, beyond its dispensable regulatory role in the inhibition of eIF2B by eIF (alpha P).

We previously identified FLVCR2 to function as a receptor for FY981 feline leukemia virus (FeLV). However, the cellular function of FLVCR2 remains unresolved. Here, we report the cellular function of FLVCR2 as an importer of heme, based on the following observations. First, FLVCR2 binds to hemin-conjugated agarose, and binding is competed by free hemin. Second, mammalian cells and Xenopus laevis oocytes expressing FLVCR2 display enhanced heme uptake. Third, heme import is reduced after the expression of FLVCR2-specific small interfering RNA (siRNA) or after the binding of the FY981 FeLV envelope protein to the FLVCR2 receptor. Finally, cells overexpressing FLVCR2 are more sensitive to heme toxicity, a finding most likely attributable to enhanced heme uptake. Tissue expression analysis indicates that FLVCR2 is expressed in a broad range of human tissues, including liver, placenta, brain, and kidney. The identification of a cellular function for FLVCR2 will have important implications in elucidating the pathogenic mechanisms of Fowler syndrome and of phenotypically associated disorders.

Our laboratory previously discovered a family of synaptic adhesion-like molecules (SALMs) which induce neurite outgrowth in this brain region (Wang et al., 2006). Here we establish flotillin-1 (flot-1) as a molecular mediator of neurite branching for SALM4. Knockdown of flot-1 alone in cultured hippocampal neurons using siRNA from 3-7 days in vitro (DIV) impaired neurite branching, whereas overexpression of flot-1 during the same time period increased the number of processes and branching. We show that induction of neurite outgrowth by flot-1 depends on amino acids 134-151 as well as lipid raft microdomains, SoHo proteins to regulate the actin cytoskeleton, and the exocyst complex to deliver new membrane proteins to growing neurites. When each of SALMs 1-5 was overexpressed, siRNA knockdown of flot-1 prevented neurite branching by SALM4. Overall, our data reveal a flot-1 signaling pathway for hippocampal neurite branching that is regulated by SALM4. (C) 2010 Published by Elsevier Inc.

Inhibitors of MAP kinases or PI 3-kinase prevented the stimulatory action of Neurotropin, indicating that neuronal TrkB/CREB pathway mediates the action. Repetitive oral administration of Neurotropin (200 NU/kg/day, 3 months) prevented the age-dependent decline in hippocampal BDNF expression in Ts65Dn mice, a model of Down's syndrome. This effect was associated with the improvement of spatial cognition of the mice. These results open an intriguing new strategy in which Neurotropin may prove beneficial treatment for neurodegenerative disorders. (C) 2010 Elsevier Inc. All rights reserved.

A major limitation for experimental studies of current ES/iPS cell differentiation protocols is the lack of VM DA neurons with a stable phenotype as defined by an expression marker code of FOXA2/TH/beta-tubulin. Here we demonstrate a combination of three modifications that were required to produce VM DA neurons. Firstly, early and specific exposure to 10(-8) M (low dose) retinoic acid improved the regional identity of neural progenitor cells derived from human ES cells, PD or healthy subject-specific iPS cells. Secondly, a high activity form of human sonic hedgehog established a sizeable FOXA2(+) neural progenitor cell population in vitro. Thirdly, early exposure to FGF8a, rather than Fgf8b, and WNT1 was required for robust differentiation of the FOXA2(+) floor plate-like human neural progenitor cells into FOXA2(+) DA neurons. FOXA2(+) DA neurons were also generated when this protocol was adapted to feeder-free conditions. In summary, this new human ES and iPS cell differentiation protocol using FGF8a, WNT1, low dose retinoic acid and a high activity form of SHH can generate human VM DA neurons that are required for relevant new bioassays, drug discovery and cell based therapies for PD.

We performed a mutational analysis of the ADAMTS gene family in human melanoma and identified a large fraction of melanomas to harbor somatic mutations. To evaluate the functional consequences of the most commonly mutated gene, ADAMTS18, six of its mutations were biologically examined. ADAMTS18 mutations had little effect on melanoma cell growth under standard conditions, but reduced cell dependence on growth factors. ADAMTS18 mutations also reduced adhesion to laminin and increased migration in vitro and metastasis in vivo. Melanoma cells expressing mutant ADAMTS18 had reduced cell migration after short hairpin RNA-mediated knockdown of ADAMTS18, suggesting that ADAMTS18 mutations promote growth, migration, and metastasis in melanoma.

Activation of peroxisome proliferator-activated receptor. has been associated with anticancer activities in a variety of cancer cell lines through inhibition of proliferation and promotion of apoptosis. We examined the effect of pioglitazone on lung cancer development in carcinogen-induced lung adenocarcinoma and squamous cell carcinoma (SCC). When pioglitazone was administered beginning 8 weeks after the first carcinogen treatment when microscopic adenomas already existed, pioglitazone significantly inhibited tumor load (sum of tumor volume per lung in average) by 64% (P < 0.05) in p53(wt/wt) mice and 50% (P < 0.05) in p53(wt/Ala135Val) mice in the lung adenocarcinoma model. Delayed administration of pioglitazone caused a limited (35%, P < 0.05) decrease in lung SCC. Induction of apoptosis occurred in both model systems. These data show that pioglitazone significantly inhibited progression of both adenocarcinoma and SCC in the two mouse model systems. Mol Cancer Ther; 9(11); 3074-82. (C) 2010 AACR.

TI Genome-Wide Association for Smoking Cessation Success in a Trial of Precessation Nicotine Replacement SO MOLECULAR MEDICINE LA English DT Article ID SAMPLE-SIZE CALCULATIONS; MOLECULAR-GENETICS; LUNG-CANCER; DEPENDENCE; BEHAVIOR; GENES; METAANALYSIS; ADDICTION; DISEASE; POWER AB Abilities to successfully quit smoking display substantial evidence for heritability in classic and molecular genetic studies. Genome-wide association (GWA) studies have demonstrated single-nucleotide polymorphisms (SNPs) and haplotypes that distinguish successful quitters from individuals who were unable to quit smoking in clinical trial participants and in community samples. Many of the subjects in these clinical trial samples were aided by nicotine replacement therapy (NRI). We now report novel GWA results from participants in a clinical trial that sought dose/response relationships for "precessation" NRT. In this trial, 369 European-American smokers were randomized to 21 or 42 mg NRT, initiated 2 wks before target quit dates. Ten-week continuous smoking abstinence was assessed on the basis of self-reports and carbon monoxide levels. SNP genotyping used Affymetrix 6.0 arrays. GWA results for smoking cessation success provided no P value that reached "genome-wide" significance. Compared with chance, these results do identify (a) more clustering of nominally positive results within small genomic regions, (b) more overlap between these genomic regions and those identified in six prior successful smoking cessation GWA studies and (c) sets of genes that fall into gene ontology categories that appear to be biologically relevant. The 1,000 SNPs with the strongest associations form a plausible Bayesian network; no such network is formed by randomly selected sets of SNPs. The data provide independent support, based on individual genotyping, for many loci previously nominated on the basis of data from genotyping in pooled DNA samples. These results provide further support for the idea that aid for smoking cessation may be personalized on the basis of genetic predictors of outcome.

TI Survivin Is Not Induced by Novel Taxanes SO MOLECULAR PHARMACEUTICS LA English DT Article DE Taxanes; chemotherapy; survivin; paclitaxel; prostate cancer; breast cancer; lung cancer ID BREAST-CANCER CELLS; PROSTATE-CANCER; LUNG-CANCER; CHEMOTHERAPY; EXPRESSION; MITOXANTRONE; PREDNISONE; PACLITAXEL; DOCETAXEL; APOPTOSIS AB Taxanes are a critical component of chemotherapy for breast, prostate, lung and other cancers. Initial or acquired tumor resistance to taxanes is therefore one of the most important issues in oncology. Survivin is a prosurvival gene whose expression is a poor prognostic feature. Survivin is induced acutely upon exposure to taxanes and coordinates resistance to taxane-mediated cell death, although the exact mechanism of taxane-mediated survivin induction is not clear. Here, we describe the synthesis of a series of novel taxanes, with modifications on the 7- or 10-position of the taxane backbone, as well as the side chain. We found that the novel taxanes with modifications at the 10-position have robust tubulin binding and tubulin polymerization activity. Gene expression profiling and quantitative PCR of cells treated with the 10-position conjugates reveals that the effect of treatment with a subset of these novel taxanes lacks a gene expression signature, including survivin induction, which is characteristically induced with paclitaxel treatment. Furthermore, we show that this gene expression signature is not due to differences in G2/M arrest. Cell sensitivity studies suggest that the inability to induce survivin is associated with increased drug cytotoxicity and apoptosis. This work suggests that taxanes that effectively bind tubulin need not invariably induce survivin as a mechanism of drug resistance.

We used the integration of statistical and functional approaches to discover a novel gene that contributes to ADHD. For our statistical approach, we started with a linkage study based on large multigenerational families in a population isolate, followed by fine mapping of targeted regions using a family-based design. Family- and population-based association studies in five samples from disparate regions of the world were used for replication. Brain imaging studies were performed to evaluate gene function. The linkage study discovered a genome region harbored in the Latrophilin 3 gene (LPHN3). In the world-wide samples (total n=6360, with 2627 ADHD cases and 2531 controls) statistical association of LPHN3 and ADHD was confirmed. Functional studies revealed that LPHN3 variants are expressed in key brain regions related to attention and activity, affect metabolism in neural circuits implicated in ADHD, and are associated with response to stimulant medication. Linkage and replicated association of ADHD with a novel non-candidate gene (LPHN3) provide new insights into the genetics, neurobiology, and treatment of ADHD.

Nationally representative data are reported here for the prevalence and correlates of a surrogate measure of DSM-IV rapid cycling BPD from the National Comorbidity survey Replication (NCS-R), a national survey of the US household population. DSM-IV disorders were assessed in the NCS-R with the WHO Composite International Diagnostic Interview (CIDI). Although the CIDI did not assess rapid cycling, it did assess the broader category of 12-month BPD with frequent mood episodes (FMEs), having at least four episodes of mania/hypomania or major depression in the 12 months before interview. Roughly one-third of NCS-R respondents with lifetime DSM-IV BPD and half with 12-month BPD met criteria for FME. FME was associated with younger age-of-onset (of BP-I, but not BP-II) and higher annual persistence (73% of the years since first onset of illness with an episode) than non-FME BPD. No substantial associations of FME vs non-FME BPD were found with socio-demographics, childhood risk factors (parental mental disorders, other childhood adversities) or comorbid DSM-IV disorders. However, FME manic episodes had greater clinical severity than non-FME episodes (assessed with a fully structured version of the Young Mania Rating Scale) and FME hypomanic episodes had greater role impairment than non-FME episodes (assessed with the Sheehan Disability Scales). Whether these indicators of severity merely reflect attenuated effects of rapid cycling or independent effects of sub-threshold rapid cycling warrants further study given the high proportion of lifetime cases who met criteria for FME.

This article explores the unusual neuroinflammation targeting of dendrimers (with no targeting ligands) in the brain, with significant consequences for nanoscale materials in medicine. Method: The in vivo biodistribution of fluorescent-labeled neutral generation-4-polyamidoamine dendrimers (similar to 4 nm) in a rabbit model of cerebral palsy was explored following subarachnoid administration. Results: These dendrimers, with no targeting ligands, were localizing in activated microglia and astrocytes (cells responsible for neuroinflammation), even in regions far moved from the site of injection, in newborn rabbits with maternal inflammation-induced cerebral palsy. Conclusion: This intrinsic ability of dendrimers to localize inactivated microglia and astrocytes can enable targeted delivery of therapeutics in disorders such as cerebral palsy, Alzheimer's and multiple sclerosis.

TI TRPM7 is essential for Mg2+ homeostasis in mammals SO NATURE COMMUNICATIONS LA English DT Article ID SECONDARY HYPOCALCEMIA; ION-CHANNEL; PROTEIN-KINASES; ALPHA-KINASES; MAGNESIUM; HYPOMAGNESEMIA; MUTATION; DOMAIN; CELL; CURRENTS AB Mg2+ is the second-most abundant cation in animal cells and is an essential cofactor in numerous enzymatic reactions. The molecular mechanisms controlling Mg2+ balance in the organism are not well understood. In this study, we report identification of TRPM7, a bifunctional protein containing a protein kinase fused to an ion channel, as a key regulator of whole body Mg2+ homeostasis in mammals. We generated TRPM7-deficient mice with the deletion of the kinase domain. Homozygous TRPM7(Delta kinase) mice demonstrated early embryonic lethality, whereas heterozygous mice were viable, but developed signs of hypomagnesaemia and revealed a defect in intestinal Mg2+ absorption. Cells derived from heterozygous TRPM7(Delta kinase) mice demonstrated reduced TRPM7 currents that had increased sensitivity to the inhibition by Mg2+. Embryonic stem cells lacking TRPM7 kinase domain displayed a proliferation arrest phenotype that can be rescued by Mg2+ supplementation. Our results demonstrate that TRPM7 is essential for the control of cellular and whole body Mg2+ homeostasis.

CA MAGIC TI Association analyses of 249,796 individuals reveal 18 new loci associated with body mass index SO NATURE GENETICS LA English DT Article ID GENOME-WIDE ASSOCIATION; GASTRIC-INHIBITORY POLYPEPTIDE; MELANOCORTIN-4 RECEPTOR GENE; GLUCOSE-HOMEOSTASIS; COMMON VARIANTS; ADULT OBESITY; EARLY-ONSET; FTO GENE; FAT MASS; RISK AB Obesity is globally prevalent and highly heritable, but its underlying genetic factors remain largely elusive. To identify genetic loci for obesity susceptibility, we examined associations between body mass index and similar to 2.8 million SNPs in up to 123,865 individuals with targeted follow up of 42 SNPs in up to 125,931 additional individuals. We confirmed 14 known obesity susceptibility loci and identified 18 new loci associated with body mass index (P < 5 x 10(-8)), one of which includes a copy number variant near GPRC5B. Some loci (at MC4R, POMC, SH2B1 and BDNF) map near key hypothalamic regulators of energy balance, and one of these loci is near GIPR, an incretin receptor. Furthermore, genes in other newly associated loci may provide new insights into human body weight regulation.

CA MAGIC TI Meta-analysis identifies 13 new loci associated with waist-hip ratio and reveals sexual dimorphism in the genetic basis of fat distribution SO NATURE GENETICS LA English DT Article ID GENOME-WIDE ASSOCIATION; CORONARY-HEART-DISEASE; BODY-FAT; METABOLIC RISK; ABDOMINAL ADIPOSITY; GLUCOSE-HOMEOSTASIS; SUSCEPTIBILITY LOCI; INSULIN-RESISTANCE; COMMON VARIANTS; OBESITY AB Waist-hip ratio (WHR) is a measure of body fat distribution and a predictor of metabolic consequences independent of overall adiposity. WHR is heritable, but few genetic variants influencing this trait have been identified. We conducted a meta-analysis of 32 genome-wide association studies for WHR adjusted for body mass index (comprising up to 77,167 participants), following up 16 loci in an additional 29 studies (comprising up to 113,636 subjects). We identified 13 new loci in or near RSPO3, VEGFA, TBX15-WARS2, NFE2L3, GRB14, DNM3-PIGC, ITPR2-SSPN, LY86, HOXC13, ADAMTS9, ZNRF3-KREMEN1, NISCH-STAB1 and CPEB4 (P = 1.9 x 10(-9) to P = 1.8 x 10(-40)) and the known signal at LYPLAL1. Seven of these loci exhibited marked sexual dimorphism, all with a stronger effect on WHR in women than men (P for sex difference = 1.9 x 10(-3) to P = 1.2 x 10(-13)). These findings provide evidence for multiple loci that modulate body fat distribution independent of overall adiposity and reveal strong gene-by-sex interactions.

TI A multi-stage genome-wide association study of bladder cancer identifies multiple susceptibility loci SO NATURE GENETICS LA English DT Article ID CONFERS SUSCEPTIBILITY; UDP-GLUCURONOSYLTRANSFERASES; RECOMBINATION HOTSPOTS; TELOMERASE MUTATIONS; PULMONARY-FIBROSIS; SEQUENCE VARIANT; COMMON VARIANTS; CHROMOSOME 8Q24; DOWN-REGULATION; CELL-CARCINOMA AB We conducted a multi-stage, genome-wide association study of bladder cancer with a primary scan of 591,637 SNPs in 3,532 affected individuals (cases) and 5,120 controls of European descent from five studies followed by a replication strategy, which included 8,382 cases and 48,275 controls from 16 studies. In a combined analysis, we identified three new regions associated with bladder cancer on chromosomes 22q13.1, 19q12 and 2q37.1: rs1014971, (P = 8 x 10(-12)) maps to a non-genic region of chromosome 22q13.1, rs8102137 (P = 2 x 10(-11)) on 19q12 maps to CCNE1 and rs11892031 (P = 1 x 10(-7)) maps to the UGT1A cluster on 2q37.1. We confirmed four previously identified genome-wide associations on chromosomes 3q28, 4p16.3, 8q24.21 and 8q24.3, validated previous candidate associations for the GSTM1 deletion (P = 4 x 10(-11)) and a tag SNP for NAT2 acetylation status (P = 4 x 10(-11)), and found interactions with smoking in both regions. Our findings on common variants associated with bladder cancer risk should provide new insights into the mechanisms of carcinogenesis.

TI IFI16 is an innate immune sensor for intracellular DNA SO NATURE IMMUNOLOGY LA English DT Article ID CYTOSOLIC DNA; CYTOPLASMIC DNA; I INTERFERONS; IFN-BETA; RECOGNITION; PROTEIN; ACTIVATION; RNA; INFLAMMASOME; INDUCTION AB The detection of intracellular microbial DNA is critical to appropriate innate immune responses; however, knowledge of how such DNA is sensed is limited. Here we identify IFI16, a PYHIN protein, as an intracellular DNA sensor that mediates the induction of interferon-beta (IFN-beta). IFI16 directly associated with IFN-beta-inducing viral DNA motifs. STING, a critical mediator of IFN-beta responses to DNA, was recruited to IFI16 after DNA stimulation. Lowering the expression of IFI16 or its mouse ortholog p204 by RNA-mediated interference inhibited gene induction and activation of the transcription factors IRF3 and NF-kappa B induced by DNA and herpes simplex virus type 1 (HSV-1). IFI16 (p204) is the first PYHIN protein to our knowledge shown to be involved in IFN-beta induction. Thus, the PYHIN proteins IFI16 and AIM2 form a new family of innate DNA sensors we call 'AIM2-like receptors' (ALRs).

TI The TLX1 oncogene drives aneuploidy in T cell transformation SO NATURE MEDICINE LA English DT Article ID ACUTE LYMPHOBLASTIC-LEUKEMIA; GENE-EXPRESSION; TRANSGENIC MICE; MUTATIONS; HOX11; SURVIVAL; BCL11B; NOTCH1; LYMPHOMAGENESIS; LYMPHOCYTES AB The TLX1 oncogene (encoding the transcription factor T cell leukemia homeobox protein-1) has a major role in the pathogenesis of T cell acute lymphoblastic leukemia (T-ALL). However, the specific mechanisms of T cell transformation downstream of TLX1 remain to be elucidated. Here we show that transgenic expression of human TLX1 in mice induces T-ALL with frequent deletions and mutations in Bcl11b (encoding B cell leukemia/lymphoma-11B) and identify the presence of recurrent mutations and deletions in BCL11B in 16% of human T-ALLs. Most notably, mouse TLX1 tumors were typically aneuploid and showed a marked defect in the activation of the mitotic checkpoint. Mechanistically, TLX1 directly downregulates the expression of CHEK1 (encoding CHK1 checkpoint homolog) and additional mitotic control genes and induces loss of the mitotic checkpoint in nontransformed preleukemic thymocytes. These results identify a previously unrecognized mechanism contributing to chromosomal missegregation and aneuploidy active at the earliest stages of tumor development in the pathogenesis of cancer.

TI Utilizing targeted cancer therapeutic agents in combination: novel approaches and urgent requirements SO NATURE REVIEWS DRUG DISCOVERY LA English DT Article ID RENAL-CELL CARCINOMA; METASTATIC COLORECTAL-CANCER; PHASE-II TRIAL; SYNTHETIC LETHAL SCREEN; ADP-RIBOSE POLYMERASE; EARLY CLINICAL-TRIALS; BREAST-CANCER; LUNG-CANCER; KINASE INHIBITOR; DRUG-DEVELOPMENT AB The rapid development of new therapeutic agents that target specific molecular pathways involved in tumour cell proliferation provides an unprecedented opportunity to achieve a much higher degree of biochemical specificity than previously possible with traditional chemotherapeutic anticancer agents. However, the lack of specificity of these established chemotherapeutic drugs allowed a relatively straightforward approach to their use in combination therapies. Developing a paradigm for combining new, molecularly targeted agents, on the other hand, is substantially more complex. The abundance of molecular data makes it possible, at least in theory, to predict how such agents might interact across crucial growth control networks. Initial strategies to examine molecularly targeted agent combinations have produced a small number of successes in the clinic. However, for most of these combination strategies, both in preclinical models and in patients, it is not clear whether the agents being combined actually hit their targets to induce growth inhibition. Here, we consider the initial approach of the US National Cancer Institute (NCI) to the evaluation of combinations of molecularly targeted anticancer agents in patients and provide a description of several new approaches that the NCI has initiated to improve the effectiveness of combination-targeted therapy for cancer.

These observations are providing a molecular explanation for fundamental aspects of B cell responses, including antigen affinity discrimination and the value of class switching, as well as insights into the underlying causes of B cell tumorigenesis. Advances in our understanding of the earliest molecular events that follow antigen binding to the BCR may provide a general framework for the initiation of signalling in the adaptive immune system.

If so, surveillance for genetic markers of adaptation could help to predict the risk of disease emergence. However, adaptation is difficult to distinguish conclusively from the other processes that generate genetic change. In this Review we survey the research on the host jumps of influenza A, severe acute respiratory syndrome-coronavirus, canine parvovirus and Venezuelan equine encephalitis virus to illustrate the insights that can arise from combining genetic surveillance with microbiological experimentation in the context of epidemiological data. We argue that using a multidisciplinary approach for surveillance will provide a better understanding of when adaptations are required for host jumps and thus when predictive genetic markers may be present.

Mutations in Fas that disrupt the DISC cause autoimmune lymphoproliferative syndrome (ALPS). Here we show that the Fas-FADD death domain (DD) complex forms an asymmetric oligomeric structure composed of 5-7 Fas DD and 5 FADD DD, whose interfaces harbor ALPS-associated mutations. Structure-based mutations disrupt the Fas-FADD interaction in vitro and in living cells; the severity of a mutation correlates with the number of occurrences of a particular interaction in the structure. The highly oligomeric structure explains the requirement for hexameric or membrane-bound FasL in Fas signaling. It also predicts strong dominant negative effects from Fas mutations, which are confirmed by signaling assays. The structure optimally positions the FADD death effector domain (DED) to interact with the caspase-8 DED for caspase recruitment and higher-order aggregation.

Although STAT1 is widely considered a tumor suppressor, it remains unclear, however, if this function occurs in tumor cells ( cell autonomous) or if STAT1 acts primarily through immune cells. Here, the question of whether STAT1 has a cell autonomous role in mammary tumor formation was addressed in a mouse model of ERBB2/neu-induced breast cancer in the absence and presence of STAT1. For this purpose, mice that carry floxed Stat1 alleles, which permit cell-specific removal of STAT1, were generated. To induce tumors only in mammary cells lacking STAT1, Stat1 floxed mice were crossed with transgenic mice that express cre recombinase and the neu oncogene under the mouse mammary tumor virus LTR (Stat1fl/fl NIC). Stat1 was effectively deleted in mammary epithelium of virgin Stat1fl/fl NIC females. Time-to-tumor onset was significantly shorter in Stat1fl/fl NIC females than in WT NIC ( Wilcoxon rank sum test, P = .02). The median time-to-tumor onset in the Stat1fl/fl NIC mice was 49.4 weeks, whereas it was 62.4 weeks in the WT NIC mice. These results suggest that STAT1 in mammary epithelial cells may play a role in suppressing tumorigenesis. The Stat1 floxed allele described in this study is also a unique resource to determine the cellular targets of IFNs and STAT1 action, which should aid our understanding and appreciation of these pathways.

TI Brain cancer incidence trends in relation to cellular telephone use in the United States SO NEURO-ONCOLOGY LA English DT Article DE brain cancer; cellular telephones; epidemiology; SEER ID CENTRAL-NERVOUS-SYSTEM; MOBILE PHONES; TUMOR-INCIDENCE; TIME TRENDS; 1900 MHZ; RATES; RISK AB The use of cellular telephone has grown explosively during the past two decades, and there are now more than 279 million wireless subscribers in the United States. If cellular phone use causes brain cancer, as some suggest, the potential public health implications could be considerable. One might expect the effects of such a prevalent exposure to be reflected in general population incidence rates, unless the induction period is very long or confined to very long-term users. To address this issue, we examined temporal trends in brain cancer incidence rates in the United States, using data collected by the Surveillance, Epidemiology, and End Results (SEER) Program. Log-linear models were used to estimate the annual percent change in rates among whites. With the exception of the 20-29-year age group, the trends for 1992-2006 were downward or flat. Among those aged 20-29 years, there was a statistically significant increasing trend between 1992 and 2006 among females but not among males. The recent trend in 20-29-year-old women was driven by a rising incidence of frontal lobe cancers. No increases were apparent for temporal or parietal lobe cancers, or cancers of the cerebellum, which involve the parts of the brain that would be more highly exposed to radiofrequency radiation from cellular phones. Frontal lobe cancer rates also rose among 20-29-year-old males, but the increase began earlier than among females and before cell phone use was highly prevalent. Overall, these incidence data do not provide support to the view that cellular phone use causes brain cancer.

In order to identify candidate genes and pathways responsible for the preservation of cognitive function by exercise, we trained mice that had been exposed to lifelong running or sedentary lifestyle for 16 months in the hippocampus-dependent water maze. After water maze training, we analyzed the expression of 24,000 genes in the hippocampus using Illumina bead microarray. Runners show greater activation of genes associated with synaptic plasticity and mitochondrial function, and also exhibit significant downregulation of genes associated with oxidative stress and lipid metabolism. Running also modified the effects of learning on the expression of genes involved in cell excitability, energy metabolism, and insulin, MAP kinase and Wnt signaling. These results suggest that the enhancement of cognitive function by lifelong exercise is associated with an altered transcriptional profile following learning. Published by Elsevier Inc.

The circuit level manifestations of these drug-induced plastic changes and predispositions to drug dependence are poorly understood in preclinical models and virtually unknown in human drug dependence Using whole-brain resting-state fMRI connectivity analysis with 'seed voxels' placed within individual nodes of the MCL system, we report network-specific functional connectivity strength decreases in cocaine users within distinct circuits of the system, including between ventral tegmental area (VIA) and a region encompassing thalamus/lentiform nucleus/nucleus accumbens, between amygdala and medial prefrontal cortex (mPFC). and between hippocampus and dorsal mPFC Further, regression analysis on regions showing significant functional connectivity decrease in chronic cocaine users revealed that the circuit strength between VTA and thalamus/lentiform nucleus/nucleus accumbens was negatively correlated with years of cocaine use This is the first evidence of circuit-related changes in human cocaine dependence and is consistent with the range of cognitive and behavioral disruptions seen in cocaine dependence.

The extent to which abnormal reward-related neural signals can be observed in chronic, medicated patients with schizophrenia (SZ), however, is not clear. In an fMRI study involving 17 chronic outpatients with SZ and 17 matched controls, we used a monetary incentive delay (MID) task, in which different-colored shapes predicted gains, losses, or neutral outcomes. Subjects needed to respond to a target within a time window in order to receive the indicated gain or avoid the indicated loss. Group differences in blood-oxygen-level-dependent responses to cues and outcomes were assessed through voxel-wise whole-brain analyses and regions-of-interest analyses in the neostriatum and prefrontal cortex (PFC). Significant group by outcome valence interactions were observed in the medial and lateral PFC, lateral temporal cortex, and amygdalae, such that controls, but not patients, showed greater activation for gains, relative to losses. In the striatum, neural activity was modulated by outcome magnitude in both groups. Additionally, we found that ratings of negative symptoms in patients correlated with sensitivity to obtained losses in medial PFC, obtained gains in lateral PFC, and anticipated gains in left ventral striatum. Sensitivity to obtained gains in lateral PFC also correlated with positive symptom scores in patients. Our findings of systematic relationships between clinical symptoms and neural responses to stimuli associated with rewards and punishments offer promise that reward-related neural responses may provide sensitive probes of the effectiveness of treatments for negative symptoms.

A total of 52 male and female outpatients meeting criteria for recurrent major depressive or bipolar disorder participated in a double-blind, randomized, placebo-controlled, crossover clinical trial involving seven i.v. infusions of placebo or scopolamine (4 mu g/kg). Following a single-blind placebo lead-in, participants entered either a placebo-block/scopolamine-block or a scopolamine-block/placebo-block sequence. Each block included three sessions. Clinical ratings were acquired before each infusion and included the Montgomery-Asberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Rating Scale (HAM-A). A treatment group x block interaction (F = 21.0, p<0.001) was observed in MADRS scores across gender, and the reduction was significant by the evaluation following the first scopolamine administration (F = 8.4, p = 0.006). The treatment group x block interaction was also significant in males (F = 3.8, p = 0.043) and females (F = 35.6, p<0.001) separately. A block x gender interaction (F = 7.4, p = 0.009) indicated that the response magnitude was larger in women. The treatment x block interaction was significant for the HAM-A across gender (F = 12.0, p<0.001), and was significant for females (F = 24.9, p<0.001) but not for males (F = 1.3, p = 0.30). When comparing the baseline block to study end, the block x gender interaction (F = 12.6, p = 0.001) showed that the antianxiety response was greater in women. Men and women show a rapid antidepressant response following scopolamine, but the magnitude of response is larger in women than in men.

Recent studies on intracranial self-administration of neurochemicals (drugs) found that rats learn to self-administer various drugs into the mesolimbic dopamine structures the posterior ventral tegmental area, medial shell nucleus accumbens and medial olfactory tubercle. In addition, studies found roles of non-dopaminergic mechanisms of the supramammillary, rostromedial tegmental and midbrain raphe nuclei in reward. To explain intracranial self-administration and related effects of various drug manipulations, I outlined a neurobiological theory claiming that there is an intrinsic central process that coordinates various selective functions (including perceptual, visceral, and reinforcement processes) into a global function of approach. Further, this coordinating process for approach arises from interactions between brain structures including those structures mentioned above and their closely linked regions: the medial prefrontal cortex, septal area, ventral pallidum, bed nucleus of stria terminalis, preoptic area, lateral hypothalamic areas, lateral habenula, periaqueductal gray, laterodorsal tegmental nucleus and parabrachical area.

These neurotrophic factors also play important roles in the survival and function of adult neurons, learning and memory, and synaptic plasticity. Since the mid-1990s, investigators have studied the role of BDNF and GDNF in the behavioral effects of abused drugs and in the neuroadaptations induced by repeated exposure to drugs in the mesocorticolimbic dopamine system. Here, we review rodent studies on the role of BDNF and GDNF in drug reward, as assessed in the drug self-administration and the conditioned place preference procedures, and in drug relapse, as assessed in extinction and reinstatement procedures. Our main conclusion is that whether BDNF or GDNF would facilitate or inhibit drug-taking behaviors depends on the drug type, the brain site, the addiction phase (initiation, maintenance, or abstinence/relapse), and the time interval between site-specific BDNF or GDNF injections and the reward- and relapse-related behavioral assessments.

A major focus of addiction research has for a long time been on systems that mediate acute positively reinforcing effects of addictive drugs, most prominently the mesolimbic dopaminergic (DA) system and its connections. This research line has been successful in shedding light on the physiology of both natural and drug reward, but has not led to therapeutic breakthroughs. The role of classical reward systems is perhaps least clear in alcohol addiction. Here, recent work is summarized that points to some clinically important conclusions. First, important pharmacogenetic differences exist with regard to positively reinforcing effects of alcohol and the ability of this drug to activate classical reward pathways. This offers an opportunity for personalized treatment approaches in alcoholism. Second, brain stress and fear systems become pathologically activated in later stages of alcoholism and their activation is a major influence in escalation of alcohol intake, sensitization of stress responses, and susceptibility to relapse. These findings offer a new category of treatment mechanisms. Corticotropin-releasing hormone (CRH) signaling through CRH1 receptors is a major candidate target in this category, but recent data indicate that antagonists for substance P (SP) neurokinin 1 (NK1) receptors may have a similar potential.

To achieve this, we performed and blindly evaluated neonatal ABRs on a subset of infants delivering within a multicenter randomized placebo-controlled clinical trial comparing single versus repeated courses of antenatal corticosteroid treatments for women at 23-31 weeks gestation who remained at increased risk for preterm birth. The women were randomly assigned to either the single or the repeated antenatal corticosteroid treatment group. Women in the repeated antenatal corticosteroid group received weekly antenatal corticosteroid treatments until 34 weeks gestation or until they reached a study-determined limited number of courses, whereas women in the single antenatal corticosteroid group received an initial course of corticosteroid followed by weekly placebo injections. We performed ABR testing on their infants prior to discharge. The latencies of waves I, III and V and the peak-to-trough amplitudes of waves I and V were compared between those in the single (n = 27) and repeated antenatal corticosteroid treatment (n = 24) groups. The majority of repeated antenatal corticosteroid infants (20 of 24) were exposed to >= 4 antenatal corticosteroid treatments. Even though gestational age was similar between our subset of single and repeated antenatal corticosteroid treatment groups, infant birth weight and length and head circumference were significantly smaller in the repeated antenatal corticosteroid group (p<0.05). Despite these differences in birth sizes, there were no significant group differences in the ABR wave latencies or amplitudes. We concluded that our repeated antenatal corticosteroid treatments, in comparison to a single treatment, did not significantly benefit or harm the neonatal ABR despite significant effects on birth size.

Mutations in lamin A proteins, major components of the lamina, interfere with these functions and cause a set of phenotypically diverse diseases referred to as laminopathies. The phenotypic diversity of laminopathies is thought to be the result of alterations in specific protein-and chromatin interactions due to lamin A mutations. Systematic identification of lamin A-protein and -chromatin interactions will be critical to uncover the molecular etiology of laminopathies.

In our recent work we partially replaced the membrane vesicles in the reconstitution mix with protein-free liposomes to explore the relative contributions of cytosolic and transmembrane proteins. Here we discuss our finding that cytosolic proteins mediate fusion between membranes lacking functional transmembrane proteins and the role of membrane fusion in endoplasmic reticulum and nuclear envelope reorganization. Cytosol-dependent liposome fusion has allowed us to restore, without adding transmembrane nucleoporins, functionality of nuclear pores, their spatial distribution and chromatin decondensation in nuclei formed at insufficient amounts of membrane material and characterized by only partial decondensation of chromatin and lack of nuclear transport. Both the mechanisms and the biological implications of the discovered coupling between spatial distribution of nuclear pores, chromatin decondensation and nuclear transport are discussed.

The lamina is an important regulator of nuclear structural integrity as well as nuclear processes, including transcription, DNA replication and chromatin remodeling. The major components of the lamina are A-and B-type lamins. Mutations in lamins impair lamina functions and cause a set of highly tissue-specific diseases collectively referred to as laminopathies. The phenotypic diversity amongst laminopathies is hypothesized to be caused by mutations affecting specific protein interactions, possibly in a tissue-specific manner. Current technologies to identify interaction partners of lamin A and its mutants are hampered by the insoluble nature of lamina components. To overcome the limitations of current technologies, we developed and applied a novel, unbiased approach to identify lamin A-interacting proteins. This approach involves expression of the high-affinity OneSTrEP-tag, precipitation of lamin-protein complexes after reversible protein cross-linking and subsequent protein identification by mass spectrometry. We used this approach to identify in mouse embryonic fibroblasts and cardiac myocyte NklTAg cell lines proteins that interact with lamin A and its mutant isoform progerin, which causes the premature aging disorder Hutchinson-Gilford progeria syndrome (HGPS). We identified a total of 313 lamina-interacting proteins, including several novel lamin A interactors, and we characterize a set of 35 proteins which preferentially interact with lamin A or progerin.

This paper offers a comparative thematic analysis of the models available to inform knowledge development, transfer, and utilization. Literature searches identified 47 models for knowledge translation. Four thematic areas emerged: (1) evidence-based practice and knowledge transformation processes, (2) strategic change to promote adoption of new knowledge, (3) knowledge exchange and synthesis for application and inquiry, and (4) designing and interpreting dissemination research. This analysis distinguishes the contributions made by leaders and researchers at each phase in the process of discovery, development, and service delivery. It also informs the selection of models to guide activities in knowledge translation. A flexible theoretical stance is essential to simultaneously develop new knowledge and accelerate the translation of that knowledge into practice behaviors and programs of care that support optimal patient outcomes.

TI Effect of smoking status on total energy expenditure SO NUTRITION & METABOLISM LA English DT Article ID DOUBLY LABELED WATER; CIGARETTE-SMOKING; WEIGHT-GAIN; BODY-WEIGHT; PHYSICAL-ACTIVITY; DIETARY-INTAKE; CALORIC-INTAKE; METABOLIC-RATE; UNITED-STATES; SOCIAL-CLASS AB Individuals who smoke generally have a lower body mass index (BMI) than nonsmokers. The relative roles of energy expenditure and energy intake in maintaining the lower BMI, however, remain controversial. We tested the hypothesis that current smokers have higher total energy expenditure than never smokers in 308 adults aged 40-69 years old of which 47 were current smokers. Energy expenditure was measured by doubly labeled water during a two week period in which the subjects lived at home and performed their normal activities. Smoking status was determined by questionnaire. There were no significant differences in mean BMI (mean +/- SD) between smokers and never smokers for either males (27.8+5.1 kg/m(2) vs. 27.5+4.0 kg/m(2)) or females (26.5+5.3 kg/m(2) vs. 28.1+6.6 kg/m(2)), although the difference in females was of similar magnitude to previous reports. Similarly, total energy expenditure of male smokers (3069+764 kcal/d) was not significantly different from that of never smokers (2854+468 kcal/d), and that of female smokers (2266+387 kcal/d) was not different from that of never smokers (2330+415 kcal/d). These findings did not change after adjustment for age, fat-free mass and self-reported physical activity. Using doubly labeled water, we found no evidence of increased energy expenditure among smokers, however, it should be noted that BMI differences in this cohort also did not differ by smoking status.

TI Abdominal Subcutaneous and Visceral Adipose Tissue and Insulin Resistance in the Framingham Heart Study SO OBESITY LA English DT Article ID FATTY-ACID-METABOLISM; CARDIOVASCULAR-DISEASE; POSTMENOPAUSAL WOMEN; PREMENOPAUSAL WOMEN; MUSCLE COMPOSITION; MEASUREMENT SITE; RISK-FACTORS; OBESE MEN; SENSITIVITY; GLUCOSE AB Insulin resistance is associated with central obesity and an increased risk of cardiovascular disease. Our objective is to examine the association between abdominal subcutaneous (SAT) and visceral adipose tissue (VAT) and insulin resistance, to determine which fat depot is a stronger correlate of insulin resistance, and to assess whether there was an interaction between SAT, VAT, and age, sex, or BMI. Participants without diabetes from the Framingham Heart Study (FHS), who underwent multidetector computed tomography to assess SAT and VAT (n = 3,093; 48% women; mean age 50.4 years; mean BMI 27.6 kg/m(2)), were evaluated. Insulin resistance was measured using the homeostasis model and defined as HOMA(IR) >= 75th percentile. Logistic regression models, adjusted for age, sex, smoking, alcohol, menopausal status, and hormone replacement therapy use, were used to assess the association between fat measures and insulin resistance. The odds ratio (OR) for insulin resistance per standard deviation increase in SAT was 2.5 (95% confidence interval (CI): 2.2-2.7; P < 0.0001), whereas the OR for insulin resistance per standard deviation increase in VAT was 3.5 (95% CI: 3.1-3.9; P < 0.0001). Overall, VAT was a stronger correlate of insulin resistance than SAT (P < 0.0001 for SAT vs. VAT comparison). After adjustment for BMI, the OR of insulin resistance for VAT was 2.2 (95% CI: 1.9-2.5; P < 0.0001). We observed an interaction between VAT and BMI for insulin (P interaction = 0.0004), proinsulin (P interaction = 0.003), and HOMA(IR) (P interaction = 0.003), where VAT had a stronger association in obese individuals. In conclusion, SAT and VAT are both correlates of insulin resistance; however, VAT is a stronger correlate of insulin resistance than SAT.

METHODS: Using retrospective observational data, we compared 15,136 gestations born late preterm with 170,593 deliveries between 37 0/7 and 41 6/7 weeks. We defined the following categories of precursors for late preterm delivery: "spontaneous labor," "premature rupture of the membranes (preterm PROM)," "indicated" delivery, and "unknown." Incidences of neonatal morbidities were calculated according to category of precursor stratified by gestational age at delivery. Neonatal morbidities and mortality associated with potentially avoidable deliveries (eg, "soft" precursors or elective) were compared between late preterm births and neonates born at 37-40 weeks. RESULTS: Late preterm birth comprised 7.8% of all births and 65.7% of preterm births. Percentages of precursors were 29.8% spontaneous labor, 32.3% preterm PROM, 31.8% "indicated" (obstetric, maternal, or fetal condition), and 6.1% unknown. Different precursors for delivery were associated with varying incidences of neonatal morbidity. One in 15 neonates delivered late preterm for "soft" or elective precursors, and neonatal morbidity and mortality were increased compared with delivery at or after 37 weeks for these same indications. CONCLUSION: A significant number of late preterm births were potentially avoidable. Elective deliveries should be postponed until 39 weeks of gestation.

METHODS: This retrospective cohort study of prepregnancy risk factors compared 712 singleton antepartum stillbirths with 174,097 singleton live births at or after 23 weeks of gestation. The risk of term antepartum stillbirth then was assessed in a subset of 155,629 singleton pregnancies. RESULTS: In adjusted multivariable analyses, African-American race, Hispanic ethnicity, maternal age 35 years or older, nulliparity, prepregnancy body mass index (BMI) 30 or higher, preexisting diabetes, chronic hypertension, smoking, and alcohol use were independently associated with stillbirth. Prior cesarean delivery and history of preterm birth were associated with increased stillbirth risk in multiparous women. The risk of a term stillbirth for women who were white, 25-29 years old, normal weight, multiparous, no chronic hypertension, and no preexisting diabetes was 0.8 per 1,000. Term stillbirth risk increased with the following conditions: preexisting diabetes (3.1 per 1,000), chronic hypertension (1.7 per 1,000), African-American race (1.8 per 1,000), maternal age 35 years or older (1.3 per 1,000), BMI 30 or higher (1 per 1,000), and nulliparity (0.9 per 1,000). CONCLUSION: There are multiple independent risk factors for antepartum stillbirth. However, the value of individual risk factors of race, parity, advanced maternal age (35-39 years old), and BMI to predict term stillbirth is poor. Our results do not support routine antenatal surveillance for any of these risk factors when present in isolation. (Obstet Gynecol 2010;116:1119-26) C1 [Reddy, Uma M.; Laughon, S.

Methods We evaluated job histories of 2383 incident breast cancer cases diagnosed during 2000-2003, and 2502 controls who participated in a large population-based case-control study in Poland. Industrial hygienists reviewed occupational histories and developed exposure metrics for total organic solvents and benzene. Unconditional logistic regression analyses estimated ORs and 95% CIs as the measure of association with breast cancer, controlling for breast cancer risk factors. Stratified analyses examined the potential modification by known breast cancer risk factors. Associations were also evaluated by oestrogen and progesterone receptor status and by other clinical characteristics of the tumours using polytomous regression analyses. Results Women who ever worked at jobs with organic solvents exposure had a small, non-significant increase in breast cancer risk (OR=1.16; 95% CI 0.99 to 1.4). A significant association was present for oestrogen receptor- and progesterone receptor-negative tumours (OR 1.40; 95% CI 1.1 to 1.8), but there was no association with tumours with both positive receptors (OR 0.97; 95% CI 0.8 to 1.2 (p heterogeneity: 0.008)). We did not observe trends with increasing level of exposure. Known breast cancer risk factors did not modify the association between organic solvents and breast cancer risk. No association with breast cancer was found for benzene exposure (OR 1.00; 95% CI 0.8 to 1.3). Conclusion Our study provides weak evidence for a possible association between occupational exposure to organic solvents as a class and breast cancer risk. The association might be limited to hormone receptor-negative tumours. C1 [Peplonska, Beata; Szeszenia-Dabrowska, Neonila] Nofer Inst Occupat Med, Dept Environm Epidemiol, PL-91348 Lodz, Poland.

TI YAP dysregulation by phosphorylation or Delta Np63-mediated gene repression promotes proliferation, survival and migration in head and neck cancer subsets SO ONCOGENE LA English DT Article DE YAP; p53; Delta Np63; p73; apoptosis; cancer ID SQUAMOUS-CELL CARCINOMA; YES-ASSOCIATED PROTEIN; NF-KAPPA-B; GROWTH-FACTOR-RECEPTOR; TUMOR-SUPPRESSOR; WW DOMAIN; PROANGIOGENIC CYTOKINES; HIPPO PATHWAY; DNA-DAMAGE; ACTIVATION AB Overexpression of the Yes-associated protein (YAP), and TP53 family members Delta Np63 and p73, have been independently detected in subsets of head and neck squamous cell carcinomas (HNSCCs). YAP may serve as a nuclear cofactor with Delta Np63 and p73, but the functional role of YAP and their potential relationship in HNSCCs are unknown. In this study, we show that in a subset of HNSCC lines and tumors, YAP expression is increased but localized in the cytoplasm in association with increased AKT and YAP phosphorylation, and with decreased expression of Delta Np63 and p73. In another subset, YAP expression is decreased but detectable in the nucleus in association with lower AKT and YAP phosphorylation, and with increased Delta Np63 and p73 expression. Inhibiting AKT decreased serine-127 phosphorylation and enhanced nuclear translocation of YAP. Delta Np63 bound to the YAP promoter and suppressed its expression. Transfection of a YAP-serine-127-alanine phosphoacceptor-site mutant or Delta Np63 knockdown significantly increased nuclear YAP and cell death. Conversely, YAP knockdown enhanced cell proliferation, survival, migration and cisplatin chemoresistance. Thus, YAP function as a tumor suppressor may alternatively be dysregulated by AKT phosphorylation at serine-127 and cytoplasmic sequestration, or by transcriptional repression by Delta Np63, in different subsets of HNSCC. AKT and/or Delta Np63 are potential targets for enhancing YAP-mediated apoptosis and chemosensitivity in HNSCCs.

Design: Evaluation of diagnostic test or technology. Participants: One hundred fifty volunteers (284 eyes). Methods: Participants with lens opacities of varying severity were independently graded at the slit lamp for cataract severity by 2 examiners (retinal or anterior segment specialists) using the ARLNS, which employs 3 standard photographs of increasing severity for classifying each of the 3 major types of opacity. Lens photographs were taken and graded at a reading center using the more detailed AREDS System for Classifying Cataracts from photographs. Main Outcome Measures: The Pearson correlation, weighted-kappa, and limits-of-agreement statistics were used to assess the interrater agreement of the gradings. Results: Examinations were performed on 284 lenses (150 participants). Tests of interrater reliability between pairs of clinicians showed substantial agreement between clinicians for cortical and posterior subcapsular opacities and moderate agreement for nuclear opacities. A similar pattern and strength of agreement was present when comparing scores of retinal versus anterior segment specialists. Interrater agreement between clinical and reading center gradings was not as great as inter-clinician agreement. Conclusions: Interrater agreements were in the moderate to substantial range for the clinical assessment of lens opacities. Inherent differences in cataract classification systems that rely on slit lamp vs photographic assessments of lens opacities may explain some of the disagreement noted between slit lamp and photographic gradings. Given the interrater reliability statistics for clinicians and the simplicity of the grading procedure, ARLNS is presented for use in studies requiring a simple, inexpensive method for detecting the presence and severity of the major types of lens opacities.

Design: Population-based, cross-sectional study. Participants: Forty-five thousand seven hundred forty-seven adults 50 years of age and older. Methods: Geographically defined cluster sampling was used in randomly selecting a cross-section of residents from a representative rural county within each of 9 provinces in mainland China. Participants underwent VA measurements, refraction, and a slit-lamp examination at local examination sites; those with previous cataract surgery were queried as to the year and type of surgical facility. Surgical procedure and evidence of surgery complications were noted during the examination. The principal cause of visual impairment was identified for eyes with VA of 20/40 or worse. Main Outcome Measures: Cataract surgery procedure, presenting and best-corrected distance VA, and causes of visual impairment. Results: Of 50 395 enumerated eligible persons, 45 747 (90.8%) were examined and tested for VA. The overall prevalence of cataract surgery was 2.09%. Surgical coverage among those with VA worse than 20/200 in both eyes because of cataract was 35.7%. Unoperated cataract was associated with older age, female gender, lack of education, and geographic area (province). Among the 1174 cataract-operated eyes, 31.1% had presenting VA of 20/32 or better, 15.4% had presenting VA of 20/40 to 20/63, 30.0% had presenting VA worse than 20/63 to 20/200, and 23.5% had presenting VA worse than 20/200. With best correction, the percentages were 57.6%, 6.2%, 18.5%, and 17.7%, respectively. Posterior capsule opacification, refractive error, and retinal disorders were the main causes in cataract-operated eyes with VA worse than 20/63. Conclusions: Two thirds of those with bilateral visual impairment or blindness because of cataract remain in need of sight-restoring surgery. Posterior capsule opacification and refractive error, both readily amenable to treatment, were common in cataract-operated eyes. Sustained government efforts to provide access to affordable modern cataract surgery with a greater emphasis on postoperative follow-up and the quality of VA outcomes are needed.

The process begins with the adhesion of bacteria to host receptors on epithelial cells or in the salivary pellicle covering tooth surfaces. Interbacterial cell-cell binding interactions facilitate the attachment of new species and increase the diversity of the adherent microbial population. Microbial growth in oral biofilms is influenced by the exchange of chemical signals, metabolites and toxic products between neighbouring cells. Bacterial cells on tooth surfaces (dental plaque) produce extracellular polymers such as complex carbohydrates and nucleic acids. These large molecules form a protective matrix that contributes to the development of dental caries and, possibly, to periodontitis. The identification of key microbial factors underlying each step in the formation of oral biofilms will provide new opportunities for preventative or therapeutic measures aimed at controlling oral infectious diseases.

The mechanisms underlying pancreatitis pain are not well understood. Here, the possibility that interleukin-6 (IL-6) may promote pancreatitis pain was investigated with TB-2-081 (3-O-formyl-20R,21-epoxyresibufogenin, EBRF), a small molecule IL-6 receptor antagonist that was semi-synthetically derived from natural sources. The potential activity and mechanism of TB-2-081 were investigated following the induction of persistent pancreatitis using dibutyltin dichloride (DBTC) in rats. TB-2-081 displaces the binding of IL-6 to the human recombinant soluble IL-6 receptor with apparent high affinity and inhibits IL-6 mediated cell growth. Systemic or oral, but not intrathecal, administration of TB-2-081 reversed DBTC-induced abdominal hypersensitivity in a dose-and time-dependent manner. IL-6 levels were significantly up-regulated in the dorsal root ganglia (DRG) of rats with pancreatitis on day 6 after DBTC injection. IL-6-enhanced capsaicin-evoked release of calcitonin gene-related peptide from cultured DRG neurons was blocked by TB-2-081. Our data demonstrate that TB-2-081 acts as a systemically available and orally active small molecule IL-6 receptor antagonist. TB-2-081 effectively reduces pancreatitis-induced pain through peripheral mechanisms that are likely due to (a) increased expression of IL-6 in the DRG and (b) IL-6-mediated sensitization of nociceptive neurons. The activity of TB-2-081 implicates an important role for IL-6 in sustaining pancreatitis pain. Strategies targeting IL-6 actions through small molecule antagonists may offer novel approaches to improve the therapy of chronic pancreatitis and other chronic pain states.

However, it has not been shown whether there is a causal relation between the number of conditioning trials and the resistance to extinction of placebo and nocebo responses. Here we test the effects of either one or four sessions of conditioning on the modulation of both non-painful and painful stimuli delivered to the dorsum of the foot. Placebo and nocebo manipulations were obtained by pairing green or red light to a series of stimuli that were made lower or higher with respect to a yellow light associated with a series of control stimuli. Subjects were told that the lights would indicate a treatment that would reduce or increase non-painful and painful stimuli to the foot. They were randomly assigned to either Group 1 or 2. Group 1 underwent one session of conditioning and Group 2 received four sessions of conditioning. We found that one session of conditioning (Group 1) induced nocebo responses, but not placebo responses in no pain condition. After one session of conditioning, we observed both nocebo and placebo responses to painful stimulation. However, these effects extinguished over time. Conversely, four sessions of conditioning (Group 2) induced robust placebo and nocebo responses to both non-painful and painful stimuli that persisted over the entire experiment. These findings suggest that the strength of learning may be clinically important for producing long-lasting placebo effects.

SO PEDIATRIC EMERGENCY CARE LA English DT Article DE suicide; screening; nonpsychiatric patients; feasibility ID PUBLIC-HEALTH; MENTAL-HEALTH; UNITED-STATES; CLINICAL-TRIAL; PRIMARY-CARE; BEHAVIOR; YOUTH; IMPLEMENTATION; ADOLESCENTS; CHILDHOOD AB Objective: Screening children for suicide risk when they present to the emergency department (ED) with nonpsychiatric complaints could lead to better identification and treatment of high-risk youth. Before suicide screening protocols can be implemented for nonpsychiatric patients in pediatric EDs, it is essential to determine whether such efforts are feasible. Methods: As part of an instrument validation study, ED patients (10-21 years old) with both psychiatric and nonpsychiatric presenting complaints were recruited to take part in suicide screening. Clinically significant suicidal thoughts, as measured by the Suicidal Ideation Questionnaire, and suicidal behaviors were assessed, as well as patient opinions about suicide screening. Recruitment rates for the study as well as impact on length of stay were assessed. Results: Of the 266 patients and parents approached for the study, 159 (60%) agreed to participate. For patients entering the ED for nonpsychiatric reasons (n = 106), 5.7% (n = 6) reported previous suicidal behavior, and 5.7% (n = 6) reported clinically significant suicidal ideation. There were no significant differences for mean length of stay in the ED for nonpsychiatric patients with positive triggers and those who screened negative (means, 382 [SD, 198] and 393 [SD, 166] minutes, respectively; P = 0.80). Ninety-six percent of participants agreed that suicide screening should occur in the ED. Conclusions: Suicide screening of nonpsychiatric patients in the ED is feasible in terms of acceptability to parents, prevalence of suicidal thoughts and behaviors, practicality to ED flow, and patient opinion. Future endeavors should address brief screening tools validated on nonpsychiatric populations. C1 [Horowitz, Lisa; Ballard, Elizabeth; Bosk, Abigail; Pao, Maryland] NIMH, NIH, Bethesda, MD 20892 USA.

TI Just Say "I Don't": Lack of Concordance Between Teen Report and Biological Measures of Drug Use SO PEDIATRICS LA English DT Article DE cocaine; opiates; teen; drug use ID HAIR ANALYSIS; SELF-REPORT; COCAINE USE; HOUSEHOLD SURVEY; SUBSTANCE-ABUSE; CANNABIS USE; VALIDITY; URINE; TESTS; EXPOSURE AB BACKGROUND: Prevalence estimates of illicit drug use by teens are typically generated from confidential or anonymous self-report. While data comparing teen self-report with biological measures are limited, adult studies identify varying degrees of under-reporting. METHODS: Hair analyses for cocaine, opiates and marijuana were compared to confidential teen self-and parent-reported teen drug use in a longitudinal cohort of >400 high-risk urban teens and parents. RESULTS: Both teens and parents substantially underreported recent teen cocaine and opiate use. However, compared with parents, teens were more likely to deny biomarker-verified cocaine use. Teen specimens (hair) were 52 times more likely to identify cocaine use compared with self-report. Parent hair analyses for cocaine and opiate use were 6.5 times and 5.5 times, respectively, more likely to indicate drug use than were parental self-report. The lack of concordance between self-report and bioassay occurred despite participant's knowledge that a "certificate of confidentiality" protected both teen and adult participants, and that the biological specimens would be tested for drugs. CONCLUSIONS: These findings confirm prior reports of adult under-reporting of their own drug use while extending our understanding of teen's self-admitted drug use. The lack of concordance between teen self-or parent-reported teen drug use and biomarkers confirm our concerns that both teen-and parent-reported teen drug use is limited, at least for youth in high-risk urban settings. Methods of ascertainment other than self-or parent-report must be considered when health care providers, researchers and public health agencies attempt to estimate teen drug-use prevalence.

Mutations in recombination-activating genes (RAGs) 1 and 2 cause immunodeficiency and dysregulation ranging from severe combined immunodeficiency to Omenn syndrome to more mild immunodeficiencies. We report here the cases of 3 patients with hypomorphic RAG1 mutations with distinct presentations. One patient had granulomatous skin disease and disseminated nontuberculous mycobacteria; the second patient presented with predominantly autoimmune manifestations; and the third patient presented with relatively late onset of infections and had isolated T-cell lymphopenia. These disparate and atypical presentations of hypomorphic RAG1 mutations highlight the role of RAG1 in immune function and autoimmunity and expand the disease spectrum linked to these genes.

CA First Breath Study Grp TI High Mortality Rates for Very Low Birth Weight Infants in Developing Countries Despite Training SO PEDIATRICS LA English DT Article DE neonatal mortality; perinatal mortality; stillbirth; developing countries; health care systems; very low birth weight; prematurity ID PERINATAL-MORTALITY; NEONATAL DEATHS; CARE; IMPACT; INTERVENTIONS; STILLBIRTHS; HEALTH AB OBJECTIVE: The goal was to determine the effect of training in newborn care and resuscitation on 7-day (early) neonatal mortality rates for very low birth weight (VLBW) infants. The study was designed to test the hypothesis that these training programs would reduce neonatal mortality rates for VLBW infants. METHODS: Local instructors trained birth attendants from 96 rural communities in 6 developing countries in protocol and data collection, the World Health Organization Essential Newborn Care (ENC) course, and a modified version of the American Academy of Pediatrics Neonatal Resuscitation Program (NRP), by using a train-the-trainer model. To test the impact of ENC training, data on infants of 500 to 1499 g were collected by using a before/after, active baseline, controlled study design. A cluster-randomized, controlled trial design was used to test the impact of the NRP. RESULTS: A total of 1096 VLBW (500-1499 g) infants were enrolled, and 98.5% of live-born infants were monitored to 7 days. All-cause, 7-day neonatal mortality, stillbirth, and perinatal mortality rates were not affected by ENC or NRP training. CONCLUSIONS: Neither ENC nor NRP training of birth attendants decreased 7-day neonatal, stillbirth, or perinatal mortality rates for VLBW infants born at home or at first-level facilities. Encouragement of delivery in a facility where a higher level of care is available may be preferable when delivery of a VLBW infant is expected.

METHODS: Using a train-the-trainer model, certified research midwives sequentially trained the midwives who performed deliveries in low-risk, first-level, urban, community health clinics in 2 cities in Zambia in the protocol and data collection, in the World Health Organization Essential Newborn Care (ENC) course (universal precautions and cleanliness, routine neonatal care, resuscitation, thermoregulation, breastfeeding, kangaroo care, care of small infants, and common illnesses), and in the American Academy of Pediatrics Neonatal Resuscitation Program (in-depth basic resuscitation). Data were collected during 3 periods, after implementation of each training course. RESULTS: A total of 71 689 neonates were enrolled in the 3 study periods. All-cause, 7-day neonatal mortality rates decreased from 11.5 deaths per 1000 live births to 6.8 deaths per 1000 live births after ENC training (relative risk: 0.59 [95% confidence interval: 0.48-0.77]; P < .001), because of decreases in rates of deaths attributable to birth asphyxia and infection. Perinatal mortality rates but not stillbirth rates decreased. The 7-day neonatal mortality rate was decreased further after Neonatal Resuscitation Program training, after correction for loss to follow-up monitoring. CONCLUSIONS: ENC training for midwives reduced 7-day neonatal mortality rates in low-risk clinics. Additional in-depth basic training in neonatal resuscitation may reduce mortality rates further.

Although lithium's therapeutic mechanisms are not fully understood, substantial in vitro and in vivo evidence suggests that it has neuroprotective/neurotrophic properties against various insults, and considerable clinical potential for the treatment of several neurodegenerative conditions. Evidence from pharmacological and gene manipulation studies support the notion that glycogen synthase kinase-3 inhibition and induction of brain-derived neurotrophic factor-mediated signaling are lithium's main mechanisms of action, leading to enhanced cell survival pathways and alteration of a wide variety of downstream effectors. By inhibiting N-methyl-D-aspartate receptor-mediated calcium influx, lithium also contributes to calcium homeostasis and suppresses calcium-dependent activation of pro-apoptotic signaling pathways. In addition, lithium decreases inositol 1,4,5-trisphosphate by inhibiting phosphoinositol phosphatases, a process recently identified as a novel mechanism for inducing autophagy. Through these mechanisms, therapeutic doses of lithium have been demonstrated to defend neuronal cells against diverse forms of death insults and to improve behavioral as well as cognitive deficits in various animal models of neurodegenerative diseases, including stroke, amyotrophic lateral sclerosis, fragile X syndrome, as well as Huntington's, Alzheimer's, and Parkinson's diseases, among others. Several clinical trials are also underway to assess the therapeutic effects of lithium for treating these disorders. This article reviews the most recent findings regarding the potential targets involved in lithium's neuroprotective effects, and the implication of these findings for the treatment of a variety of diseases.

TI Muscle Architecture Predicts Maximum Strength and Is Related to Activity Levels in Cerebral Palsy SO PHYSICAL THERAPY LA English DT Article ID CROSS-SECTIONAL AREA; MOTOR FUNCTION; LOWER-LIMB; CHILDREN; ADOLESCENTS; THICKNESS; GASTROCNEMIUS; RELIABILITY; VALIDITY; MEN AB Background. Muscle architecture is known to be predictive of muscle function. However, it is unknown whether this relationship is similar in children and adolescents with and without cerebral palsy (CP). Objective. The objective of this study was to determine whether the architecture of the rectus femoris (RF) and vastus lateralis (VL) muscles was predictive of maximum voluntary knee extensor torque in children and adolescents with and without CP and whether these measures were related to activity and participation levels. Design. A case-control design was used. Methods. Eighteen participants with CP (mean age=12.0 years, SD=3.2) at Gross Motor Function Classification System (GMFCS) levels I through IV and 12 age-matched peers with typical development (mean age=12.3 years, SD=3.9) were evaluated. Muscle thickness, fascicle length, and fascicle angle of the RF and VL muscles were measured with 2-dimensional, B-mode ultrasound imaging. The activity and participation measures used for participants with CP were the Pediatric Outcomes Data Collection Instrument (PODCI) and the Activities Scale for Kids, Performance Version (ASKp). Results. When age and GMFCS level were controlled for, VL muscle thickness was the best predictor of knee extensor isometric torque in the group with CP (R(2)=.85). This prediction was similar to the prediction from VL muscle thickness and age in participants with typical development (R(2)=.91). Rectus femoris muscle fascicle length was significantly correlated with the Sports and Physical Functioning Scale of the PODCI (rho=.49), and VL muscle fascicle angle was correlated with the Transfers and Basic Mobility Scale of the PODCI (r=.47) and with ASKp Locomotion subdomain (r=.50). Limitations. A limitation of this study was the small sample size. Conclusions. Ultrasound measures of VL muscle thickness, adjusted for age and GMFCS level, were highly predictive of maximum torque and have the potential to serve as surrogate measures of voluntary strength (force-generating capacity) in children and adolescents with and without CP.

We observed variation in plasma concentrations of high-density lipoprotein (HDL) cholesterol across inbred mouse strains in response to high dietary fat intake. Several strains, including C57BL/6J, have stable levels of plasma HDL independent of diet, whereas other strains, including DBA2/J, show marked changes in plasma HDL. To explore this phenomenon further, we used publicly available data from a C57BL/6J x DBA/2J intercross to identify genetic factors that associate with HDL under high-fat diet conditions. Our analysis identified an epistatic interaction that plays a role in the buffering of HDL levels in C57BL/6J mice, and we have identified Arl4d as a candidate gene that mediates this effect. Structural modeling further elucidates the interaction of genetic factors that contribute to the robustness of HDL in response to high-fat diet in the C57BL/6J strain.

TI The Function and Three-Dimensional Structure of a Thromboxane A(2)/Cysteinyl Leukotriene-Binding Protein from the Saliva of a Mosquito Vector of the Malaria Parasite SO PLOS BIOLOGY LA English DT Article ID PLATELET COLLAGEN RECEPTORS; BLOOD-FEEDING ARTHROPODS; RHODNIUS-PROLIXUS; HIGH-AFFINITY; HUMAN-SKIN; EICOSANOID MEDIATORS; ANOPHELES-GAMBIAE; SMOOTH-MUSCLE; SHAPE CHANGE; SOFT TICKS AB The highly expressed D7 protein family of mosquito saliva has previously been shown to act as an anti-inflammatory mediator by binding host biogenic amines and cysteinyl leukotrienes (CysLTs). In this study we demonstrate that AnSt-D7L1, a two-domain member of this group from Anopheles stephensi, retains the CysLT binding function seen in the homolog AeD7 from Aedes aegypti but has lost the ability to bind biogenic amines. Unlike any previously characterized members of the D7 family, AnSt-D7L1 has acquired the important function of binding thromboxane A(2) (TXA(2)) and its analogs with high affinity. When administered to tissue preparations, AnSt-D7L1 abrogated Leukotriene C-4 (LTC4)-induced contraction of guinea pig ileum and contraction of rat aorta by the TXA(2) analog U46619. The protein also inhibited platelet aggregation induced by both collagen and U46619 when administered to stirred platelets. The crystal structure of AnSt-D7L1 contains two OBP-like domains and has a structure similar to AeD(7). In AnSt-D7L1, the binding pocket of the C-terminal domain has been rearranged relative to AeD7, making the protein unable to bind biogenic amines. Structures of the ligand complexes show that CysLTs and TXA(2) analogs both bind in the same hydrophobic pocket of the N-terminal domain. The TXA(2) analog U46619 is stabilized by hydrogen bonding interactions of the omega-5 hydroxyl group with the phenolic hydroxyl group of Tyr 52. LTC4 and occupies a very similar position to LTE4 in the previously determined structure of its complex with AeD7. As yet, it is not known what, if any, new function has been acquired by the rearranged C-terminal domain. This article presents, to our knowledge, the first structural characterization of a protein from mosquito saliva that inhibits collagen mediated platelet activation.

In this study we show that Na+/K+ pump activity is tightly regulated by a novel process, RNA editing. Three codons within the squid Na+/K+ ATPase gene can be recoded at the RNA level, and the efficiency of conversion for each varies dramatically, and independently, between tissues. At one site, a highly conserved isoleucine in the seventh transmembrane span can be converted to a valine, a change that shifts the pump's intrinsic voltage dependence. Mechanistically, the removal of a single methyl group specifically targets the process of Na+ release to the extracellular solution, causing a higher turnover rate at the resting membrane potential.

However, there is a perceived lack of robust image analysis systems required to process these diverse datasets. Most automated image analysis systems are tailored for specific types of microscopy, contrast methods, probes, and even cell types. This imposes significant constraints on experimental design, limiting their application to the narrow set of imaging methods for which they were designed. One of the approaches to address these limitations is pattern recognition, which was originally developed for remote sensing, and is increasingly being applied to the biology domain. This approach relies on training a computer to recognize patterns in images rather than developing algorithms or tuning parameters for specific image processing tasks. The generality of this approach promises to enable data mining in extensive image repositories, and provide objective and quantitative imaging assays for routine use. Here, we provide a brief overview of the technologies behind pattern recognition and its use in computer vision for biological and biomedical imaging. We list available software tools that can be used by biologists and suggest practical experimental considerations to make the best use of pattern recognition techniques for imaging assays.

Johansson, Erik TI Mismatch Repair-Independent Increase in Spontaneous Mutagenesis in Yeast Lacking Non-Essential Subunits of DNA Polymerase epsilon SO PLOS GENETICS LA English DT Article ID EUKARYOTIC REPLICATION FORK; SACCHAROMYCES-CEREVISIAE; HOMONUCLEOTIDE RUNS; MUTATION AVOIDANCE; GENOMIC DELETIONS; LIGATABLE NICK; S PHASE; DELTA; FIDELITY; ZETA AB Yeast DNA polymerase epsilon (Pol epsilon) is a highly accurate and processive enzyme that participates in nuclear DNA replication of the leading strand template. In addition to a large subunit (Pol2) harboring the polymerase and proofreading exonuclease active sites, Pol epsilon also has one essential subunit (Dpb2) and two smaller, non-essential subunits (Dpb3 and Dpb4) whose functions are not fully understood. To probe the functions of Dpb3 and Dpb4, here we investigate the consequences of their absence on the biochemical properties of Pol epsilon in vitro and on genome stability in vivo. The fidelity of DNA synthesis in vitro by purified Pol2/Dpb2, i.e. lacking Dpb3 and Dpb4, is comparable to the four-subunit Pol e holoenzyme. Nonetheless, deletion of DPB3 and DPB4 elevates spontaneous frameshift and base substitution rates in vivo, to the same extent as the loss of Pol epsilon proofreading activity in a pol2-4 strain. In contrast to pol2-4, however, the dpb3 Delta dpb4 Delta does not lead to a synergistic increase of mutation rates with defects in DNA mismatch repair. The increased mutation rate in dpb3 Delta dpb4 Delta strains is partly dependent on REV3, as well as the proofreading capacity of Pol delta. Finally, biochemical studies demonstrate that the absence of Dpb3 and Dpb4 destabilizes the interaction between Pol epsilon and the template DNA during processive DNA synthesis and during processive 3' to 5'exonucleolytic degradation of DNA. Collectively, these data suggest a model wherein Dpb3 and Dpb4 do not directly influence replication fidelity per se, but rather contribute to normal replication fork progression. In their absence, a defective replisome may more frequently leave gaps on the leading strand that are eventually filled by Pol zeta or Pol delta, in a post-replication process that generates errors not corrected by the DNA mismatch repair system.

TI Analysis of the 10q11 Cancer Risk Locus Implicates MSMB and NCOA4 in Human Prostate Tumorigenesis SO PLOS GENETICS LA English DT Article ID GENOME-WIDE ASSOCIATION; HUMAN GENE-EXPRESSION; FUNCTIONAL-ANALYSIS; COLORECTAL-CANCER; SECRETORY PROTEIN; EPITHELIAL-CELLS; FAMILY-HISTORY; NUDE MICE; MULTIPLE; SUSCEPTIBILITY AB Genome-wide association studies (GWAS) have established a variant, rs10993994, on chromosome 10q11 as being associated with prostate cancer risk. Since the variant is located outside of a protein-coding region, the target genes driving tumorigenesis are not readily apparent. Two genes nearest to this variant, MSMB and NCOA4, are strong candidates for mediating the effects of rs109939934. In a cohort of 180 individuals, we demonstrate that the rs10993994 risk allele is associated with decreased expression of two MSMB isoforms in histologically normal and malignant prostate tissue. In addition, the risk allele is associated with increased expression of five NCOA4 isoforms in histologically normal prostate tissue only. No consistent association with either gene is observed in breast or colon tissue. In conjunction with these findings, suppression of MSMB expression or NCOA4 overexpression promotes anchorage-independent growth of prostate epithelial cells, but not growth of breast epithelial cells. These data suggest that germline variation at chromosome 10q11 contributes to prostate cancer risk by influencing expression of at least two genes. More broadly, the findings demonstrate that disease risk alleles may influence multiple genes, and associations between genotype and expression may only be observed in the context of specific tissue and disease states.

TI Air Pollution and the Microvasculature: A Cross-Sectional Assessment of In Vivo Retinal Images in the Population-Based Multi-Ethnic Study of Atherosclerosis (MESA) SO PLOS MEDICINE LA English DT Article ID DIESEL-EXHAUST INHALATION; ACUTE ARTERIAL VASOCONSTRICTION; PARTICULATE MATTER EXPOSURE; CORONARY-HEART-DISEASE; LONG-TERM EXPOSURE; CARDIOVASCULAR-DISEASE; VESSEL DIAMETERS; VASCULAR CALIBER; MYOCARDIAL-INFARCTION; MACULAR DEGENERATION AB Background: Long-and short-term exposures to air pollution, especially fine particulate matter (PM(2.5)), have been linked to cardiovascular morbidity and mortality. One hypothesized mechanism for these associations involves microvascular effects. Retinal photography provides a novel, in vivo approach to examine the association of air pollution with changes in the human microvasculature. Methods and Findings: Chronic and acute associations between residential air pollution concentrations and retinal vessel diameters, expressed as central retinal arteriolar equivalents (CRAE) and central retinal venular equivalents (CRVE), were examined using digital retinal images taken in Multi-Ethnic Study of Atherosclerosis (MESA) participants between 2002 and 2003. Study participants (46 to 87 years of age) were without clinical cardiovascular disease at the baseline examination (2000-2002). Long-term outdoor concentrations of PM2.5 were estimated at each participant's home for the 2 years preceding the clinical exam using a spatio-temporal model. Short-term concentrations were assigned using outdoor measurements on the day preceding the clinical exam. Residential proximity to roadways was also used as an indicator of long-term traffic exposures. All associations were examined using linear regression models adjusted for subject-specific age, sex, race/ethnicity, education, income, smoking status, alcohol use, physical activity, body mass index, family history of cardiovascular disease, diabetes status, serum cholesterol, glucose, blood pressure, emphysema, C-reactive protein, medication use, and fellow vessel diameter. Short-term associations were further controlled for weather and seasonality. Among the 4,607 participants with complete data, CRAE were found to be narrower among persons residing in regions with increased long-and short-term levels of PM(2.5). These relationships were observed in a joint exposure model with -0.8 mm (95% confidence interval [CI]-1.1 to -0.5) and -0.4 mu m (95% CI -0.8 to 0.1) decreases in CRAE per interquartile increases in long-(3 mu g/m(3)) and short-term (9 mu g/m(3)) PM(2.5) levels, respectively. These reductions in CRAE are equivalent to 7-and 3-year increases in age in the same cohort. Similarly, living near a major road was also associated with a -0.7 mu m decrease (95% CI -1.4 to 0.1) in CRAE. Although the chronic association with CRAE was largely influenced by differences in exposure between cities, this relationship was generally robust to control for city-level covariates and no significant differences were observed between cities. Wider CRVE were associated with living in areas of higher PM(2.5) concentrations, but these findings were less robust and not supported by the presence of consistent acute associations with PM(2.5). Conclusions: Residing in regions with higher air pollution concentrations and experiencing daily increases in air pollution were each associated with narrower retinal arteriolar diameters in older individuals. These findings support the hypothesis that important vascular phenomena are associated with small increases in short-term or long-term air pollution exposures, even at current exposure levels, and further corroborate reported associations between air pollution and the development and exacerbation of clinical cardiovascular disease.

TI The ERCC6 Gene and Age-Related Macular Degeneration SO PLOS ONE LA English DT Article ID COMPLEMENT FACTOR-H; COCKAYNE-SYNDROME; OXIDATIVE STRESS; RISK; REPAIR; POLYMORPHISM; MACULOPATHY; ROTTERDAM; VARIANT; DAMAGE AB Background: Age-related macular degeneration (AMD) is the leading cause of irreversible visual loss in the developed countries and is caused by both environmental and genetic factors. A recent study (Tuo et al., PNAS) reported an association between AMD and a single nucleotide polymorphism (SNP) (rs3793784) in the ERCC6 (NM_000124) gene. The risk allele also increased ERCC6 expression. ERCC6 is involved in DNA repair and mutations in ERCC6 cause Cockayne syndrome (CS). Amongst others, photosensitivity and pigmentary retinopathy are hallmarks of CS. Methodology/Principal Findings: Separate and combined data from three large AMD case-control studies and a prospective population-based study (The Rotterdam Study) were used to analyse the genetic association between ERCC6 and AMD (2682 AMD cases and 3152 controls). We also measured ERCC6 mRNA levels in retinal pigment epithelium (RPE) cells of healthy and early AMD affected human donor eyes. Rs3793784 conferred a small increase in risk for late AMD in the Dutch population (The Rotterdam and AMRO-NL study), but this was not replicated in two non-European studies (AREDS, Columbia University). In addition, the AMRO-NL study revealed no significant association for 9 other variants spanning ERCC6. Finally, we determined that ERCC6 expression in the human RPE did not depend on rs3793784 genotype, but, interestingly, on AMD status: Early AMD-affected donor eyes had a 50% lower ERCC6 expression than healthy donor eyes (P = 0.018). Conclusions/Significance: Our meta-analysis of four Caucasian cohorts does not replicate the reported association between SNPs in ERCC6 and AMD. Nevertheless, our findings on ERCC6 expression in the RPE suggest that ERCC6 may be functionally involved in AMD. Combining our data with those of the literature, we hypothesize that the AMD-related reduced transcriptional activity of ERCC6 may be caused by diverse, small and heterogeneous genetic and/or environmental determinants.

Here, we address an important and largely overlooked issue in antigenic drift: how does the number and location of glycosylation sites affect HA evolution in man? We analyzed the glycosylation status of all full-length H1 subtype HA sequences available in the NCBI influenza database. We devised the "flow index'' (FI), a simple algorithm that calculates the tendency for viruses to gain or lose consensus glycosylation sites. The FI predicts the predominance of glycosylation states among existing strains. Our analyses show that while the number of glycosylation sites in the HA globular domain does not influence the overall magnitude of variation in defined antigenic regions, variation focuses on those regions unshielded by glycosylation. This supports the conclusion that glycosylation generally shields HA from antibody-mediated neutralization, and implies that fitness costs in accommodating oligosaccharides limit virus escape via HA hyperglycosylation.

TI Leishmania major Survival in Selective Phlebotomus papatasi Sand Fly Vector Requires a Specific SCG-Encoded Lipophosphoglycan Galactosylation Pattern SO PLOS PATHOGENS LA English DT Article ID PROTOZOAN PARASITE LEISHMANIA; SECRETED ACID-PHOSPHATASE; SURFACE LIPOPHOSPHOGLYCAN; RECOGNITION RECEPTORS; FLIES; DONOVANI; STAGE; PROMASTIGOTES; MIDGUT; POLYMORPHISMS AB Phlebotomine sand flies that transmit the protozoan parasite Leishmania differ greatly in their ability to support different parasite species or strains in the laboratory: while some show considerable selectivity, others are more permissive. In "selective'' sand flies, Leishmania binding and survival in the fly midgut typically depends upon the abundant promastigote surface adhesin lipophosphoglycan (LPG), which exhibits species-and strain-specific modifications of the dominant phosphoglycan (PG) repeat units. For the "selective'' fly Phlebotomus papatasi PpapJ, side chain galactosyl-modifications (scGal) of PG repeats play key roles in parasite binding. We probed the specificity and properties of this scGal-LPG PAMP (Pathogen Associated Molecular Pattern) through studies of natural isolates exhibiting a wide range of galactosylation patterns, and of a panel of isogenic L. major engineered to express similar scGal-LPG diversity by transfection of SCG-encoded beta 1,3-galactosyltransferases with different activities. Surprisingly, both 'poly-scGal' and 'null-scGal' lines survived poorly relative to PpapJ-sympatric L. major FV1 and other 'mono-scGal' lines. However, survival of all lines was equivalent in P. duboscql, which naturally transmit L. major strains bearing 'null-scGal'-LPG PAMPs. We then asked whether scGal-LPG-mediated interactions were sufficient for PpapJ midgut survival by engineering Leishmania donovani, which normally express unsubstituted LPG, to express a 'PpapJ-optimal' scGal-LPG PAMP. Unexpectedly, these "L. major FV1-cloaked'' L. donovani-SCG lines remained unable to survive within PpapJ flies. These studies establish that midgut survival of L. major in PpapJ flies is exquisitely sensitive to the scGal-LPG PAMP, requiring a specific 'mono-scGal' pattern. However, failure of 'mono-scGal' L. donovani-SCG lines to survive in selective PpapJ flies suggests a requirement for an additional, as yet unidentified L. major-specific parasite factor(s). The interplay of the LPG PAMP and additional factor(s) with sand fly midgut receptors may determine whether a given sand fly host is "selective'' or "permissive'', with important consequences to both disease transmission and the natural co-evolution of sand flies and Leishmania.

In previous studies we reported a series of broadly neutralizing mini-antibodies derived from a synthetic naive human combinatorial antibody library by panning against a mimetic of the trimeric N-HR coiled coil, followed by affinity maturation using targeted diversification of the CDR-H2 loop. Here we report crystal structures of the N-HR mimetic 5-Helix with two Fabs that represent the extremes of this series: Fab 8066 is broadly neutralizing across a wide panel of B and C type HIV-1 viruses, whereas Fab 8062 is non-neutralizing. The crystal structures reveal important differences in the conformations of the CDR-H2 loops in the complexes that propagate into other regions of the antigen-antibody interface, and suggest that both neutralization properties and affinity for the target can be attributed, at least in part, to the differences in the interactions of the CDR-H2 loops with the antigen. Furthermore, modeling of the complex of an N-HR trimer with three Fabs suggests that the CDR-H2 loop may be involved in close intermolecular contacts between neighboring antibody molecules, and that such contacts may hinder the formation of complexes between the N-HR trimer and more than one antibody molecule depending on the conformation of the bound CDR-H2 loop which is defined by its interactions with antigen. Comparison with the crystal structure of the complex of 5-Helix with another neutralizing monoclonal antibody known as D5, derived using an entirely different antibody library and panning procedure, reveals remarkable convergence in the optimal sequence and conformation of the CDR-H2 loop.

Matrix is the major structural protein in paramyxoviruses that mediates viral assembly and budding. Curiously, the matrix proteins of a few paramyxoviruses have been found in the nucleus, although the biological function associated with this nuclear localization remains obscure. We report here that the nuclear-cytoplasmic trafficking of the Nipah virus matrix (NiV-M) protein and associated post-translational modification play a critical role in matrix-mediated virus budding. Nipah virus (NiV) is a highly pathogenic emerging paramyxovirus that causes fatal encephalitis in humans, and is classified as a Biosafety Level 4 (BSL4) pathogen. During live NiV infection, NiV-M was first detected in the nucleus at early stages of infection before subsequent localization to the cytoplasm and the plasma membrane. Mutations in the putative bipartite nuclear localization signal (NLS) and the leucine-rich nuclear export signal (NES) found in NiV-M impaired its nuclear-cytoplasmic trafficking and also abolished NiV-M budding. A highly conserved lysine residue in the NLS served dual functions: its positive charge was important for mediating nuclear import, and it was also a potential site for monoubiquitination which regulates nuclear export of the protein. Concordantly, overexpression of ubiquitin enhanced NiV-M budding whereas depletion of free ubiquitin in the cell (via proteasome inhibitors) resulted in nuclear retention of NiV-M and blocked viral budding. Live Nipah virus budding was exquisitely sensitive to proteasome inhibitors: bortezomib, an FDA-approved proteasome inhibitor for treating multiple myeloma, reduced viral titers with an IC(50) of 2.7 nM, which is 100-fold less than the peak plasma concentration that can be achieved in humans. This opens up the possibility of using an "off-the-shelf'' therapeutic against acute NiV infection.

Prostate cancer is a genetically complex disease with locus and disease heterogeneity. The RNASEL gene and HPCX locus have been implicated in hereditary prostate cancer; however, their contributions to sporadic forms of this malignancy remain uncertain. METHODS. Associations of prostate cancer with two variants in the RNASEL gene (a founder mutation, 471delAAAG, and a non-synonymous SNP, rs486907), and with five microsatellite markers in the HPCX locus, were examined in 979 cases and 1,251 controls of Ashkenazi Jewish descent. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression models. RESULTS. There was an inverse association between RNASEL rs486907 and prostate cancer in younger men (<65 years) and those with a first-degree relative with prostate cancer; men with AA genotype had ORs of 0.64 and 0.47 (both P < 0.05), respectively, in comparison to men with GG genotype. Within the HPCX region, there were positive associations for allele 135 of bG82i1.1 marker (OR = 1.77, P = 0.01) and allele 188 of DXS1205 (OR = 1.65, P = 0.02). In addition, allele 248 of marker D33 was inversely associated (OR = 0.65, P = 0.05) with Gleason score >= 7 tumors. CONCLUSIONS. Results suggest that variants in RNASEL contribute to susceptibility to early onset and familial forms of prostate cancer, whereas HPCX variants are associated with prostate cancer risk and tumor aggressiveness. The observation that a mutation predicted to completely inactivate RNASEL protein was not associated with prostate cancer, but that a missense variant was associated, suggests that the effect is due to either partial inactivation of the protein, and/or acquisition of a new protein activity.

Data obtained at the typical experimental temperature range are not sufficient to accurately describe the variations observed in the oligomerization of these p53 fragments. It is necessary to determine a number of thermodynamic parameters, all of which can be precisely assessed using this general third-order linear fitting function. These are the heat of reaction, innate temperature-invariant enthalpy, compensatory temperatures and the thermodynamic molecular switch occurring at the thermal set point. This methodology can be used to distinguish the characteristic structure and stability of p53 carboxy-terminal fragments or other p53 mutants. It should be used for the thermodynamic characterization of any interacting biological system. C1 [Chun, Paul W.] Univ Florida, Dept Biochem & Mol Biol, Coll Med, Gainesville, FL 32610 USA.

The first crystal structure (1.09 angstrom resolution) of PR1(N) with the clinical inhibitor darunavir (DRV) reveals the same overall structure as PR1(M), but with a slightly larger inhibitor-binding cavity. Changes in the 10s loop and the flap hinge propagate to shift one flap away from the inhibitor, whereas L89F and substitutions in the 60s loop perturb inhibitor-binding residues 29-32. However, kinetic parameters of PR1(N) closely resemble those of PR1(M), and calorimetric results are consistent with similar binding affinities for DRV and two other clinical PIs, suggesting that minor DRMs coevolve to compensate for the detrimental effects of drug-specific major DRMs. A miniprecursor (TFR1-61-PR1(N)) comprising the transframe region (TFR) fused to the N-terminus of PR1(N) undergoes autocatalytic cleavage at the TFR/PR1(N) site concomitant with the appearance of catalytic activity characteristic of the dimeric, mature enzyme. This cleavage is inhibited at an equimolar ratio of precursor to DRV (similar to 6 mu M), which partially stabilizes the precursor dimer from a monomer. However, cleavage at L34/W35 within the TFR, which precedes the TFR1-61/PR1(N) cleavage at pH <= 5, is only partially inhibited. Favorable properties of PR1(N) relative to PR1(M) include its suitability for column fractionation by size under native conditions and >10-fold higher dimer dissociation constant (150 nM). Exploiting these properties may facilitate testing of potential dimerization inhibitors that perturb early precursor processing steps.

TI Structural determinants of tobacco vein mottling virus protease substrate specificity SO PROTEIN SCIENCE LA English DT Article DE tobacco vein mottling virus; tobacco etch virus; crystal structure; protease ID POLYPROTEIN CLEAVAGE SITE; ELECTRON-DENSITY MAPS; MACROMOLECULAR STRUCTURES; NUCLEAR INCLUSION; ACTIVE-SITE; IN-VIVO; PURIFICATION; EXPRESSION; NIA; PROTEINASES AB Tobacco vein mottling virus (TVMV) is a member of the Potyviridae, one of the largest families of plant viruses. The TVMV genome is translated into a single large polyprotein that is subsequently processed by three virally encoded proteases. Seven of the nine cleavage events are carried out by the NIa protease. Its homolog from the tobacco etch virus (TEV) is a widely used reagent for the removal of affinity tags from recombinant proteins. Although TVMV protease is a close relative of TEV protease, they exhibit distinct sequence specificities. We report here the crystal structure of a catalytically inactive mutant TVMV protease (K65A/K67A/C151A) in complex with a canonical peptide substrate (Ac-RETVRFQSD) at 1.7-angstrom resolution. As observed in several crystal structures of TEV protease, the C-terminus (similar to 20 residues) of TVMV protease is disordered. Unexpectedly, although deleting the disordered residues from TEV protease reduces its catalytic activity by -10-fold, an analogous truncation mutant of TVMV protease is significantly more active. Comparison of the structures of TEV and TVMV protease in complex with their respective canonical substrate peptides reveals that the S3 and S4 pockets are mainly responsible for the differing substrate specificities. The structure of TVMV protease suggests that it is less tolerant of variation at the P1' position than TEV protease. This conjecture was confirmed experimentally by determining kinetic parameters k(cat) and K(m) for a series of oligopeptide substrates. Also, as predicted by the cocrystal structure, we confirm that substitutions in the P6 position are more readily tolerated by TVMV than TEV protease.

This task switching study examined whether such type of "intentional" preparatory control relies on the presentation of explicit action effects. Preparatory BOLD activation in a condition with task-specific motion effect feedback was compared to identical task conditions with accuracy feedback only. Switch-related activation was found selectively in the effect feedback condition in the middle mid-frontal gyrus and in the anterior intraparietal sulcus. Consistent with research on attentional control, the posterior superior parietal lobule exhibited switch-related preparatory activation irrespective of feedback type. To conclude, preparatory control can occur via complementary attentional and intentional neural mechanisms depending on whether meaningful task-specific action effects lead to the formation of explicit effect representations.

Several nutritional and physiological factors have been linked to depression in adults, including low folate and vitamin B-12 and elevated tHcy levels. Methods: Data on U.S. adults (age, 20-85 years; n = 2524) from the National Health and Nutrition Examination Survey during the period 2005 to 2006 were used. Depressive symptoms were measured with the Patient Health Questionnaire (PHQ), and elevated symptoms were defined as a PHQ total score of Serum folate, vitamin B-12, and tHcy were mainly expressed as tertiles. Multiple ordinary least square (OLS), logistic, and zero-inflated Poisson regression models were conducted in the main analysis. Results: Overall, mean PHQ score was significantly higher among women compared with men. Elevated depressive symptoms (PHQ score of >= 10) were inversely associated with folate status, particularly among women (fully adjusted odds ratio [tertiles T(3), versus T(1)] = 0.37; 95% confidence interval, 0.17-0.86), but not significantly related to tHcy or vitamin B-12. No interaction was noted between the three exposures in affecting depressive symptoms. In older adults (50 years) and both sexes combined, tHcy was positively associated with elevated depressive symptoms (fully adjusted odds ratio [tertiles T(2) versus T,] = 3.01; 95% confidence interval, 1.01-9.03), although no significant dose-response relationship was found. Conclusions: Future interventions to improve mental health outcomes among U.S. adults should take into account dietary and other factors that would increase levels of serum folate.

Although many studies have examined the relationship of depression and mortality in patients with myocardial infarction, there is less understanding of the relationship between depression and long-term mortality after CABG surgery. Methods: In a prospective study, we collected data on 309 patients hospitalized after CABG surgery. Before discharge, patients were assessed for depression using the Diagnostic Interview Schedule and the Beck Depression Inventory (BDI). Subsequently, mortality data were obtained from the National Center for Health Statistics and supplemented with phone interviews. Results: Sixty-three (20%) patients met modified Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for major depressive disorder (MDD) and 87 (28%) had BDI scores of >= 10, indicating elevated depressive symptoms. Time-to-event or last follow-up phone contact ranged from 9 days to 11.5 years (median, 9.3 years). The overall mortality rate was 37.9% (117 of 309), with 20.1% (62 of 309) due to cardiac causes. Cox proportional hazard modeling showed that age (hazard ratio [HR], 1.04; p = .005), left ventricular ejection fraction (EF) (EF <0.35 [HR], 3.9;p < .001; EF, 0.35-0.49 [HR], 1.9; p = .03), and MDD (HR, 1.8; p = .04) were independent predictors of cardiac mortality. The BDI and the cognitive-affective symptoms subset of BDI symptoms were also predictors of cardiac mortality. Age, EF, and diabetes predicted all-cause mortality, but MDD did not. Conclusions: Depression, assessed both in structured interview and by BDI, was significantly associated with elevated cardiac mortality 10 years after CABG surgery.

After selecting items for the PROMIS banks based on psychometric and content considerations, we invited external content expert reviews of the degree to which the initial domain names and definitions represented the calibrated item bank content. A minimum of four content experts reviewed each item bank and recommended a domain name and definition based on item content. Domain names and definitions then were revealed to the experts who rated how well these names and definitions fit the bank content and provided recommendations for definition revisions. These reviews indicated that the PROMIS domain names and definitions remained generally representative of bank content following item pruning, but modifications to two domain names and minor to moderate revisions of all domain definitions were needed to optimize fit with the item bank content. This reevaluation of domain names and definitions following psychometric item pruning, although not previously documented in the literature, appears to be an important procedure for refining conceptual frameworks and further supporting content validity.

Chromosome translocation frequency data from three separately conducted occupational studies of ionizing radiation were pooled together. Studies 1 and 2 included 79 and 150 medical radiologic technologists, respectively, and study 3 included 83 airline pilots and 50 university faculty members (total = 155 women and 207 men; mean age = 62 years, range 34-90). Information on personal history of radiographic examinations was collected from a detailed questionnaire. We computed a cumulative red bone marrow (RBM) dose score based on the numbers and types of X-ray examinations reported with 1 unit approximating 1 mGy. Poisson regression analyses were adjusted for age and laboratory method. Mean RBM dose scores were 49, 42, and 11 for Studies 1-3, respectively (overall mean = 33.5, range 0-303). Translocation frequencies significantly increased with increasing dose score (P < 0.001). Restricting the analysis to the lowest dose scores of under 50 did not materially change these results. We conclude that chromosome damage is associated with low levels of radiation exposure from diagnostic X-ray examinations, including dose scores of approximately 50 and lower, suggesting the possibility of long-term adverse health effects.

Bioassay findings are summarized below to expand on those not stated clearly or completely in Saghir et al. (2010). Overall in these three studies animals exposed to ethylbenzene had increased tumors in rats for kidneys, testes, head (including rare neuroesthesioepitheliomas), and total malignant tumors, whilst in mice tumor incidences were increased in the lung and liver (Huff. 2002). Thus ethylbenzene was carcinogenic by two exposure routes to both sexes of two species of rodents, two strains of rats, and one strain of mice, causing collectively tumors in five different target organs and a composite of "total malignant" tumors.

Methods: This cross-sectional study included 986 premenopausal women, aged 35 to 49 years old, from the National Institute of Environmental Health Sciences (NIEHS) Uterine Fibroid Study (UFS). Uterine leiomyomata were subtyped as submucosal, intramural/subserosal, and diffuse, based on ultrasound examinations. Results: For both ethnic groups, age, age at menarche, body mass index, and current physical activity had similar associations across the 3 UL subtypes. Inverse associations with pregnancies after age 24 appeared to be stronger for the submucosal subtype. Current smoking was associated only with diffuse UL (adjusted odds ratio [aOR] = 1.97, 95% CI: 1.11, 3.51 in African Americans, aOR = 3.00, 95% CI: 1.07, 8.38 in Caucasians). Conclusions: Although the 2 focal UL subtypes had similar risk factor profiles, the diffuse UL subtype appeared to have a distinctive risk profile with regard to current smoking. Further study of the diffuse heterogeneity seen with uterine ultrasound is needed. C1 [Dragomir, Anca D.; Schroeder, Jane C.; Olshan, Andrew F.] Univ N Carolina, Dept Epidemiol, Chapel Hill, NC USA.

One hundred women aged 18-40 years who were undergoing laparoscopy provided 20 cm(3) of blood for toxicologic analysis and surgeons completed operative reports regarding the presence of endometriosis. Gas chromatography with electron capture was used to quantify (ng/g serum) six OCPs. Logistic regression was utilized to estimate the adjusted odds ratios (aOR) and 95% confidence intervals (Cl) for individual pesticides and groups based on chemical structure adjusting for current cigarette smoking and lipids. The highest tertile of aromatic fungicide was associated with a fivefold risk of endometriosis (aOR = 5.3: 95% CI, 1.2-23.6) compared to the lowest tertile. Similar results were found for t-nonachlor and HCB. These are the first such findings in a laproscopic cohort that suggest an association between OCP exposure and endometriosis. More prospective studies are necessary to ensure temporal ordering and confirm these findings. Published by Elsevier Inc. C1 [Cooney, Maureen A.; Louis, Germaine M.

Intravitreal injections of anti-vascular endothelial growth factor (VEGF) medications have become standard of care for the treatment of the wet form of the disease. Recent reports have demonstrated an association with various immune factors. We aimed to investigate the effect of immunosuppressive therapy in the clinical course of the wet form of the disease. We compared anti-VEGF therapy plus one of three systemic immunosuppressive therapies versus anti-VEGF therapy alone for recurrent choroidal neovascularization associated with age-related macular degeneration. Methods: This was a pilot, Phase I/II, prospective, randomized, unmasked, single-center trial. Patients with subretinal exudation secondary to recurrent choroidal neovascularization associated with age-related macular degeneration were included in the study. Patients were randomized to 1 of 3 systemic arms immunosuppressive agents (daclizumab, rapamycin, or infliximab) for 6 months plus intraocular anti-VEGF therapy if indicated, compared with a group who received only anti-VEGF therapy if indicated. Results: The number of anti-VEGF injections per group, visual acuity, retinal thickness, and safety measures were assessed in all groups. Thirteen patients were randomized; comparing anti-VEGF injections before and during the study, a decrease in the number of injections from 0.73 injections per month to 0.42 for daclizumab and from 0.67 to 0.34 for sirolimus was seen, while no apparent decrease was seen for either infliximab or observation. Visual acuities were maintained in all groups. Conclusion: These preliminary data suggest that some immunosuppressive agents given systemically can alter the clinical course of the wet form of the disease and support the notion that more definitive clinical trials of immune mediation of age-related macular degeneration are indicated.

The filoviruses are endemic primarily in resource-poor regions in Central Africa and are also potential agents of bioterrorism. Although no vaccines or antiviral drugs for Marburg or Ebola are currently available, remarkable progress has been made over the last decade in developing candidate preventive vaccines against filoviruses in nonhuman primate models. Due to the generally remote locations of filovirus outbreaks, a single-injection vaccine is desirable. Among the prospective vaccines that have shown efficacy in nonhuman primate models of filoviral hemorrhagic fever, two candidates, one based on a replication-defective adenovirus serotype 5 and the other on a recombinant VSV (rVSV), were shown to provide complete protection to nonhuman primates when administered as a single injection. The rVSV-based vaccine has also shown utility when administered for postexposure prophylaxis against filovirus infections. A VSV-based Ebola vaccine was recently used to manage a potential laboratory exposure. Copyright (C) 2010 John Wiley & Sons, Ltd.

The viral RNA within these particles shows clear evidence of the action of a nucleic acid chaperone (NAC): the genomic RNA is dimeric, and a cellular tRNA molecule is annealed, by its 3' 18 nucleotides, to a complementary stretch in the viral RNA, in preparation for priming reverse transcription in the next round of infection. It seems very likely that the NAC that has catalyzed dimerization and tRNA annealing is the NC domain of the Gag protein itself. However, neither the dimeric linkage nor the tRNA: viral RNA complex has the same structure as those in mature virus particles: thus the conformational effects of Gag within the particles are not equivalent to those of the free NC protein present in mature particles. It is not known whether these dissimilarities reflect intrinsic differences in the NAC activities of Gag and NC, or limitations on Gag imposed by the structure of the immature particle. Analysis of the interactions of recombinant Gag proteins with nucleic acids is complicated by the fact that they result in assembly of virus-like particles. Nevertheless, the available data indicates that the affinity of Gag for nucleic acids can be considerably higher than that of free NC. This enhanced affinity may be due to contributions of the matrix domain, a positively charged region at the N-terminus of Gag; interactions of neighboring Gag molecules with each other may also increase the affinity due to cooperativity of the binding. Recombinant HIV-1 Gag protein clearly exhibits NAC activity. In two well-studied experimental systems, Gag was more efficient than NC, as its NAC effects could be detected at a significantly lower molar ratio of protein to nucleotide than with NC. In one system, binding of nucleic acid by the matrix domain of Gag retarded the Gag-induced annealing of two RNAs; this effect could be ameliorated by the competitive binding of inositol hexakisphosphate to the matrix domain.

Nucleic acid chaperoning is a key function for NC through the action of its conserved basic amino acids and zinc-finger structures. NC manipulates genomic RNA from its packaging in the producer cell to reverse transcription into the infected host cell. This chaperone function, in conjunction with NCs aggregating properties, is up-modulated by successive NC processing events, from the Gag precursor to the fully mature protein, resulting in the condensation of the nucleocapsid within the capsid shell. Reverse transcription also depends on NC processing, whereas this process provokes NC dissociation from double-stranded DNA, leading to a preintegration complex (PIC), competent for host chromosomal integration. In addition NC interacts with cellular proteins, some of which are involved in viral budding, and also with several viral proteins. All of these properties are reviewed here, focusing on HIV-1 as a paradigmatic reference and highlighting the plasticity of the nucleocapsid architecture.

This activity is essential for virus replication and has a critical role in mediating highly specific and efficient reverse transcription. NC's function in this process depends upon three properties: (1) ability to aggregate nucleic acids; (2) moderate duplex destabilization activity; and (3) rapid on-off binding kinetics. Here, we present a detailed molecular analysis of the individual events that occur during viral DNA synthesis and show how NC's properties are important for almost every step in the pathway. Finally, we also review biological aspects of reverse transcription during infection and the interplay between NC, reverse transcriptase and human APOBEC3G, an HIV-1 restriction factor that inhibits reverse transcription and virus replication in the absence of the HIV-1 Vif protein.

An extension of his approaches is considered here to approximate various probabilities of correlated events. Compared with multiple-integrations, our proposed method, the parallelogram formulas, based on a one-dimensional integral, not only substantially reduces the computational complexity but also maintains good accuracy. Applications of the proposed method to genetic association studies and group sequential analysis are investigated in detail. Numerical results including real data analysis and simulation studies demonstrate that the proposed method performs well.

It is caused by a virus with a complex replication cycle that occurs in multiple genotypes, of which the four most prevalent (1, 2, 3, and 4) exhibit differences in clinical behavior and responses to therapy. Chronic hepatitis C virus (HCV) in particular has evolved from a disease with no known treatment to one with several primary treatment options, none of which is uniformly effective, and a growing list of secondary treatment options for those who have failed to respond to, or relapsed after initial therapy. As treatment is often associated with significant side effects, it is now a disease that presents clinicians with multiple important decisions: whom to treat, when and with what to treat them initially, and how to manage patients who have failed during initial therapy to achieve a sustained virological response, the gold standard of effective therapy. This review examines each of these important decisions, presenting evidence to help guide clinicians in their choices. The decisions are addressed sequentially as they arise during the initial evaluation and subsequent treatment of a typical, newly recognized patient with chronic HCV, and the considerations facing the clinician when the patient has failed to achieve an SVR.

We investigated HPV16 and 18 seroepidemiology among young, unvaccinated women aged between 18 and 25. Materials and Methods: We conducted a cross-sectional evaluation of the enrollment visit in the ongoing community-based HPV16/18 Costa Rica Vaccine Trial. Prevaccination serum immunoglobulin G (IgG) antibodies were measured against HPV16 and HPV18 by enzyme-linked immunosorbent assay; cervical samples were tested for HPV DNA using Hybrid Capture 2 and SPF(10)/LiPA(25). Seroprevalence and its correlates were evaluated using unconditional logistic regression. Results: Among 5871 nonvirginal women, HPV16 and 18 seroprevalences were 30.8% and 28.1%, HPV16 and HPV18 DNA prevalences were 8.3% and 3.2%, respectively. About 37% of HPV16 DNA-positives and 42% of HPV18 DNA-positives were seronegative. Seroprevalence increased with time since sexual debut, whereas DNA prevalence did not. The correlates of HPV16 and/or 18 seropositivity were related to sexual behaviors, particularly higher number of lifetime sexual partners. There was no evidence of assay cross-reactivity as HPV16 seroprevalence was similar (approximately 34%) among women singly infected with genetically and nongenetically related species (alpha 9 and non-alpha 9); likewise, seropositivity to HPV18 was similar (approximately 30%) among women singly infected with alpha 7 and non-alpha 7 species. Conclusions: The increasing seroprevalence observed with time since first sex suggests that HPV serology is a cumulative marker of HPV exposure. However, many DNA infected women were seronegative; thus, serology is an imperfect measure of past exposure to cervical HPV, at best. Additionally, we found no evidence of assay cross-reactivity.

It is currently thought that MDB arises from aberrantly functioning stem cells in the cerebellum that fail to maintain proper control of self-renewal. Additionally, it has been reported that MDB cells display higher endogenous Notch signaling activation, known to promote the survival and proliferation of neoplastic neural stem cells and to inhibit their differentiation. Although interaction between hypoxia-inducible factor-1 alpha (HIF-1 alpha) and Notch signaling is required to maintain normal neural precursors in an undifferentiated state, an interaction has not been identified in MDB. Here, we investigate whether hypoxia, through HIF-1 alpha stabilization, modulates Notch1 signaling in primary MDB-derived cells. Our results indicate that MDB-derived precursor cells require hypoxic conditions for in vitro expansion, whereas acute exposure to 20% oxygen induces tumor cell differentiation and death through inhibition of Notch signaling. Importantly, stimulating Notch1 activation with its ligand Dll4 under hypoxic conditions leads to expansion of MDB-derived CD133(+) and nestin(+) precursors, suggesting a regulatory effect on stem cells. In contrast, MDB cells undergo neuronal differentiation when treated with gamma-secretase inhibitor, which prevents Notch activation. These results suggest that hypoxia, by maintaining Notch1 in its active form, preserves MDB stem cell viability and expansion.

Unfortunately, it has been difficult to investigate the origins of these stem cells and the mechanisms of their development, especially in mammals. Intestinal remodeling during frog metamorphosis offers a unique opportunity for such studies. During the transition from an herbivorous tadpole to a carnivorous frog, the intestine is completely remodeled as the larval epithelial cells undergo apoptotic degeneration and are replaced by adult epithelial cells developed de novo. The entire metamorphic process is under the control of thyroid hormone, making it possible to control the development of the adult intestinal stem cells. Here, we show that the thyroid hormone receptor-coactivator protein arginine methyltransferase 1 (PRMT1) is upregulated in a small number of larval epithelial cells and that these cells dedifferentiate to become the adult stem cells. More importantly, transgenic overexpression of PRMT1 leads to increased adult stem cells in the intestine, and conversely, knocking down the expression of endogenous PRMT1 reduces the adult stem cell population. In addition, PRMT1 expression pattern during zebrafish and mouse development suggests that PRMT1 may play an evolutionally conserved role in the development of adult intestinal stem cells throughout vertebrates. These findings are not only important for the understanding of organ-specific adult stem cell development
