To better understand the migration and proliferation mechanisms of implanted cells, a means to track cells in living subjects is essential, and to achieve that, a number of cell labeling techniques have been developed. Nanoparticles, with their superior physical properties, have become the materials of choice in many investigations along this line. Owing to inherent magnetic, optical or acoustic attributes, these nanoparticles can be detected by corresponding imaging modalities in living subjects at a high spatial and temporal resolution. These features allow implanted cells to be separated from host cells; and have advantages over traditional histological methods, as they permit non-invasive, real-time tracking in vivo. This review attempts to give a summary of progress in using nanotechnology to monitor cell trafficking. We will focus on direct cell labeling techniques, in which cells ingest nanoparticles that bear traceable signals, such as iron oxide or quantum dots. Ferritin and MagA reporter genes that can package endogenous iron or iron supplement into iron oxide nanoparticles will also be discussed.

Yet, some of the most promising nano-materials currently under investigation demonstrate prolonged tissue retention and contain heavy metals. This presents serious concerns for toxicity and additionally, prolonged particle retention may interfere with diagnostic imaging and testing modalities. The creation of nano-sized particles and molecules with optimal pharmacokinetics and clearance characteristics will minimize toxicity risks by reducing the duration of exposure to these agents. Given that many types of nano materials possess easily modifiable surface chemistry, if nanoparticle characteristics associated with optimal pharmacokinetics and clearance from the body were well established, it would be feasible to design and create agents with more favorable clearance properties. In this talk, based on our experiences of dendrimer-based nano-sized MRI/Optical/Nuclear multimodality imaging agents, I will discuss the physiologic clearance of nano-sized particle and molecule, especially focusing on renal mechanisms, as well as provides an extended view of current research investigating clearance of other types of nano-sized particles and molecules, including dendrimers, quantum dots, and carbon, gold, and silica-based nanoparticles.

The antioxidant activity was also monitored by the DDPH method, while the chemical composition of active EO was assessed by GC-MS analysis. The results showed that the EOs obtained from Thymus hirtus sp. algeriensis (rich on monoterpenoids, especially linalool at 17.62% and camphor at 13.82%) is significantly active against both L. major and L. infantum, whereas Ruta chalepensis EO (rich on 2-undecanone at 84.28%) is only active against L. infantum. Both oil extracts showed low cytotoxicity towards murine macrophages. The characteristic ratios (IC80 Raw264.7 cells/IC50 L. infantum and IC80 Raw264.7 cells/IC50 L. major) were, respectively, 2.7 and 1.57 for T. hirtus sp. algeriensis, and 1.34 and 0.19 for R. chalepensis. However, when measuring the antioxidant effects (DDPH method), the two latter EOs presented a moderate 2,2-diphenyl-2-picrylhydrazyl hydrate scavenging effects compared to EOs from Eucaliptus globulus, Pinus halepensis, Pituranthos tortuosus, Rosmarinus officinalis, Tetraclinis articulata or to BHT.

We show here that myosin-Va acts as a point-to-point organelle transporter to pull ER as cargo into Purkinje neuron spines. Specifically, myosin-Va accumulates at the ER tip as the organelle moves into spines, and hydrolysis of ATP by myosin-Va is required for spine ER targeting. Moreover, myosin-Va is responsible for almost all of the spine ER insertion events. Finally, attenuation of the ability of myosin-Va to move along actin filaments reduces the maximum velocity of ER movement into spines, providing direct evidence that myosin-Va drives ER motility. Thus, we have established that an actin-based motor moves ER within animal cells, and have uncovered the mechanism for ER localization to Purkinje neuron spines, a prerequisite for synaptic plasticity.

Two loci on the regions of 2p21 and 11q13.3 were associated with RCC susceptibility below genome-wide significance. Two correlated variants (r(2) = 0.99 in controls), rs11894252 (P = 1.8 x 10(-8)) and rs7579899 (P = 2.3 x 10(-9)), map to EPAS1 on 2p21, which encodes hypoxia-inducible-factor-2 alpha, a transcription factor previously implicated in RCC. The second locus, rs7105934, at 11q13.3, contains no characterized genes (P = 7.8 x 10(-14)). In addition, we observed a promising association on 12q24.31 for rs4765623, which maps to SCARB1, the scavenger receptor class B, member 1 gene (P = 2.6 x 10(-8)). Our study reports previously unidentified genomic regions associated with RCC risk that may lead to new etiological insights.

The extent of AID's promiscuity and its predilection for immunoglobulin genes are unknown. We report here that AID interacted broadly with promoter-proximal sequences associated with stalled polymerases and chromatin-activating marks. In contrast, genomic occupancy of replication protein A (RPA), an AID cofactor, was restricted to immunoglobulin genes. The recruitment of RPA to the immunoglobulin loci was facilitated by phosphorylation of AID at Ser38 and Thr140. We propose that stalled polymerases recruit AID, thereby resulting in low frequencies of hypermutation across the B cell genome. Efficient hypermutation and switch recombination required AID phosphorylation and correlated with recruitment of RPA. Our findings provide a rationale for the oncogenic role of AID in B cell malignancy.

Two opposing models have been proposed for the deamination of DNA or RNA by AID. Although most data support DNA deamination, there is no physical evidence of uracil residues in immunoglobulin genes. Here we demonstrate their presence by determining the sensitivity of DNA to digestion with uracil DNA glycosylase (UNG) and abasic endonuclease. Using several methods of detection, we identified uracil residues in the variable and switch regions. Uracil residues were generated within 24 h of B cell stimulation, were present on both DNA strands and were found to replace mainly cytosine bases. Our data provide direct evidence for the model that AID functions by deaminating cytosine residues in DNA.

We show here that deletion of the DNA-binding inhibitor Id3 resulted in the defective generation of Foxp3(+) regulatory T cells (T-reg cells). We identify two transforming growth factor-beta 1 (TGF-beta 1)-dependent mechanisms that were vital for activation of Foxp3 transcription and were defective in Id3(-/-) CD4(+) T cells. Enhanced binding of the transcription factor E2A to the Foxp3 promoter promoted Foxp3 transcription. Id3 was required for relief of inhibition by the transcription factor GATA-3 at the Foxp3 promoter. Furthermore, Id3(-/-) T cells showed greater differentiation into the T(H)17 subset of helper T cells in vitro and in a mouse asthma model. Therefore, a network of factors acts in a TGF-beta-dependent manner to control Foxp3 expression and inhibit the development of T(H)17 cells.

The distance between the soma and nerve terminal is great, making efficient anterograde Trk transport critical for Trk synaptic translocation and signaling. The mechanism responsible for this trafficking remains poorly understood. Here we show that the sorting receptor sortilin interacts with TrkA, TrkB and TrkC and enables their anterograde axonal transport, thereby enhancing neurotrophin signaling. Cultured DRG neurons lacking sortilin showed blunted MAP kinase signaling and reduced neurite outgrowth upon stimulation with NGF. Moreover, deficiency for sortilin markedly aggravated TrkA, TrkB and TrkC phenotypes present in p75(NTR) knockouts, and resulted in increased embryonic lethality and sympathetic neuropathy in mice heterozygous for TrkA. Our findings demonstrate a role for sortilin as an anterograde trafficking receptor for Trk and a positive modulator of neurotrophin-induced neuronal survival.

However, it has been difficult to exploit these advantages, because circular YACs are difficult to isolate and purify. Here we describe a method for purification of large circular YACs that is more reliable compared with previously described protocols. This method has been used to purify YACs up to 600 kb in size. The purified YAC DNA is suitable for restriction enzyme digestion, DNA sequencing and functional studies. For example, YACs carrying full-size genes can be purified from yeast and used for transfection into mammalian cells or for the construction of a synthetic genome that can be used to produce a synthetic cell. This method for isolating high-quality YAC DNA in microgram quantities should be valuable for functional and synthetic genomic studies. The entire protocol takes similar to 3 d to complete.

Despite advances in device therapy and surgery, the mainstay of treatment for these disorders remains pharmacological. Hypertension affects two-thirds of older adults and remains a potent risk factor for coronary artery disease, chronic heart failure, atrial fibrillation, and stroke in this age group. Numerous trials have demonstrated reduction in these adverse outcomes with antihypertensive drugs. After acute myocardial infarction, beta-adrenergic blockers reduce mortality regardless of patient age. Statins and antiplatelet drugs have proven beneficial in both primary and, especially, secondary prevention of coronary events in older adults. In elders with chronic heart failure, loop diuretics must be used cautiously, owing to their higher potential for adverse effects, whereas angiotensin-converting-enzyme inhibitors and beta-blockers reduce symptoms and prolong survival. The high risk of stroke in elderly patients with atrial fibrillation is markedly reduced with warfarin, although bleeding risk is increased. The high prevalence of polypharmacy among older adults with cardiovascular disease, coupled with age-associated physiological changes and comorbidities, provides major challenges in adherence and avoidance of drug-related adverse events.

However, innate immune sensing of commensal microorganisms in the intestinal tract does not lead to chronic intestinal inflammation in healthy individuals, reflecting the intricacy of the regulatory mechanisms that tame the inflammatory response in the gut. Recent findings suggest that innate immune responses to commensal microorganisms, although once considered to be harmful, are necessary for intestinal homeostasis and immune tolerance. This Review discusses recent findings that identify a crucial role for innate immune effector molecules in protection against colitis and colitis-associated colorectal cancer and the therapeutic implications that ensue.

Technical advances in spatial and temporal resolution and new labelling tools have enabled researchers to directly observe the activation process. Consequently, research using imaging approaches to study lymphocyte activation has expanded, providing an unprecedented level of cellular and molecular detail in the field. As a result, certain models of lymphocyte activation have been verified, others have been revised and yet others have been replaced with new concepts. In this article, we review the current imaging techniques that are used to assess lymphocyte activation in different contexts, from whole animals to single molecules, and discuss the advantages and potential limitations of these methods.

This effort has been hampered by the lack of natural protective immunity against HIV. As a result, most of the studies have focused on long-term non-progressive infection or other clinical situations, none of which fully recapitulates protective immunity against HIV. Although this effort has been successful in defining characteristics of T cells in acute and non-progressive HIV infection, and has therefore greatly expanded our knowledge of the immunopathogenesis of AIDS, its success in defining immune correlates of protection is less clear. In this Opinion article we offer a perspective on how successful this effort has been in defining immune correlates of protection that have been, or will be, of use in the development of an HIV vaccine. Our view is that investing in an iterative approach to human vaccine efficacy trials of sufficient size and sampling frequency will improve the likelihood that an immune correlate of vaccine protection will be defined.

Mitophagy, the specific autophagic elimination of mitochondria, has been identified in yeast, mediated by autophagy-related 32 (Atg32), and in mammals during red blood cell differentiation, mediated by NIP3-like protein X (NIX; also known as BNIP3L). Moreover, mitophagy is regulated in many metazoan cell types by parkin and PTEN-induced putative kinase protein 1 (PINK1), and mutations in the genes encoding these proteins have been linked to forms of Parkinson's disease.

Involvement of ATP7A in axonal outgrowth, synapse integrity and neuronal activation underscores the fundamental importance of copper metabolism to neurological function. Defects in ATP7A cause Menkes disease, an infantile-onset, lethal condition. Neonatal diagnosis and early treatment with copper injections enhance survival in patients with this disease, and can normalize clinical outcomes if mutant ATP7A molecules retain small amounts of residual activity. Gene replacement rescues a mouse model of Menkes disease, suggesting a potential therapeutic approach for patients with complete loss-of-function ATP7A mutations. Remarkably, a newly discovered ATP7A disorder-isolated distal motor neuropathy-has none of the characteristic clinical or biochemical abnormalities of Menkes disease or its milder allelic variant occipital horn syndrome (OHS), instead resembling Charcot-Marie-Tooth disease type 2. These findings indicate that ATP7A has a crucial but previously unappreciated role in motor neuron maintenance, and that the mechanism underlying ATP7A-related distal motor neuropathy is distinct from Menkes disease and OHS pathophysiology. Collectively, these insights refine our knowledge of the neurology of ATP7A-related copper transport diseases and pave the way for further progress in understanding ATP7A function.

In mammals, the main CNS pathway controlling voluntary movement is the corticospinal tract, which encompasses connections between the cerebral motor cortex and the spinal cord. Hereditary spastic paraplegias (HSPs) are a group of genetic disorders that lead to a length-dependent, distal axonopathy of fibres of the corticospinal tract, causing lower limb spasticity and weakness. Recent work aimed at elucidating the molecular cell biology underlying the HSPs has revealed the importance of basic cellular processes-especially membrane trafficking and organelle morphogenesis and distribution-in axonal maintenance and degeneration.

The yeast dynamin-related protein Dnm1 has been localized to sites of mitochondrial division. Using cryo-EM, we have determined the three-dimensional (3D) structure of Dnm1 in a GTP-bound state. The 3D map showed that Dnm1 adopted a unique helical assembly when compared with dynamin, which is involved in vesicle scission during endocytosis. Upon GTP hydrolysis, Dnm1 constricted liposomes and subsequently dissociated from the lipid bilayer. The magnitude of Dnm1 constriction was substantially larger than the decrease in diameter previously reported for dynamin. We postulate that the larger conformational change is mediated by a flexible Dnm1 structure that has limited interaction with the underlying bilayer. Our structural studies support the idea that Dnm1 has a mechanochemical role during mitochondrial division.

Strand-invasion products are processed by either the double-strand break repair (DSBR) or synthesis-dependent strand annealing (SDSA) pathway. D-loops destined to be processed by SDSA need to dissociate, producing non-crossovers, and those destined for DSBR should resist dissociation to generate crossovers. The mechanism that channels recombination intermediates into different homologous-recombination pathways is unknown. Here we show that D-loops in a human DMC1-driven reaction are substantially more resistant to dissociation by branch-migration proteins such as RAD54 than those formed by RAD51. We propose that the intrinsic resistance to dissociation of DMC1 strand-invasion intermediates may account for why DMC1 is essential to ensure the proper segregation of chromosomes in meiosis.

This prompted us to identify particular proteins to better understand the underlying mechanism. Total proteins from ovarian epithelial tumor (OET) cells treated with gonadotropins were analyzed by proteomics. Western blot and immunohistochemistry were used to validate the target protein (prohibitin) and to detect its expression in human ovarian tissue of serous tumors. As the results, prohibitin was found to be significantly up-regulated by LH, with a maximum of 2.5-fold increase at the concentration of 200 mIU/mL. The expression of prohibitin was steadily decreased from benign serous cystadenomas to borderline tumors and serous carcinomas (P < 0.0001). The difference between any two groups was significant (P < 0.001). Collectively, data from this study indicate that prohibitin is one LH-associated protein and it may be protective of ovarian cancer development and progression, supporting that LH may play an inhibitory role in ovarian tumorigenesis.

Early efforts to identify kidney disease susceptibility genetic loci using linkage and candidate gene strategies proved disappointing. More recently, genome-wide association studies have yielded highly promising results suggesting a number of potential candidate genes and genomic regions that may contribute to the pathogenesis of CKD. Renal failure susceptibility genes identified by these methods, such as MYH9, have yielded novel insights into the pathogenesis of CKD. Genome-wide association studies of CKD are beginning to define the genomic architecture of kidney disease and will impact our understanding of how genetic variation influences susceptibility to this condition.

TI Anti-Inflammatory Effects of Chronic Aspirin on Brain Arachidonic Acid Metabolites (Retracted article. See vol. 40, pg. 1094, 2015) SO NEUROCHEMICAL RESEARCH LA English DT Article; Retracted Publication DE Aspirin; Neuroinflammation; Eicosanoids; Arachidonic acid; Lipoxin A(4); 15-epi-lipoxin A(4) ID LOW-DOSE ASPIRIN; FACTOR-KAPPA-B; LIPOXIN A(4); RAT-BRAIN; TRIGGERED 15-EPI-LIPOXINS; CYCLOOXYGENASE ISOZYMES; ALZHEIMERS-DISEASE; GENE-EXPRESSION; LEUKOTRIENE B-4; EICOSANOIDS AB Pro-inflammatory and anti-inflammatory mediators derived from arachidonic acid (AA) modulate peripheral inflammation and its resolution. Aspirin (ASA) is a unique non-steroidal anti-inflammatory drug, which switches AA metabolism from prostaglandin E-2 (PGE(2)) and thromboxane B-2 (TXB2) to lipoxin A(4) (LXA(4)) and 15-epi-LXA(4). However, it is unknown whether chronic therapeutic doses of ASA are anti-inflammatory in the brain. We hypothesized that ASA would dampen increases in brain concentrations of AA metabolites in a rat model of neuroinflammation, produced by a 6-day intracerebroventricular infusion of bacterial lipopolysaccharide (LPS). In rats infused with LPS (0.5 ng/h) and given ASA-free water to drink, concentrations in high-energy microwaved brain of PGE(2), TXB2 and leukotriene B-4 (LTB4) were elevated. In rats infused with artificial cerebrospinal fluid, 6 weeks of treatment with a low (10 mg/kg/day) or high (100 mg/kg/day) ASA dose in drinking water decreased brain PGE(2), but increased LTB4, LXA(4) and 15-epi-LXA(4) concentrations. Both doses attenuated the LPS effects on PGE(2), and TXB2. The increments in LXA(4) and 15-epi-LXA(4) caused by high-dose ASA were significantly greater in LPS-infused rats. The ability of ASA to increase anti-inflammatory LXA(4) and 15-epi-LXA(4) and reduce pro-inflammatory PGE(2) and TXB2 suggests considering aspirin further for treating clinical neuroinflammation.

TI Effects of Cocaine-Kindling on the Expression of NMDA Receptors and Glutamate Levels in Mouse Brain SO NEUROCHEMICAL RESEARCH LA English DT Article DE Cocaine; Seizure; Kindling; Glutamate; Microdialysis; NMDA receptor ID METHYL-D-ASPARTATE; EXCITATORY AMINO-ACIDS; IN-VIVO MICRODIALYSIS; EXTRACELLULAR GLUTAMATE; INDUCED CONVULSIONS; REVERSE TOLERANCE; RAT; HIPPOCAMPUS; ANTAGONISTS; MICE AB In the present study we examined the effects of cocaine seizure kindling on the expression of NMDA receptors and levels of extracellular glutamate in mouse brain. Quantitative autoradiography did not reveal any changes in binding of [(3)H] MK-801 to NMDA receptors in several brain regions. Likewise, in situ hybridization and Western blotting revealed no alteration in expression of the NMDA receptor subunits, NR1 and NR2B. Basal overflow of glutamate in the ventral hippocampus determined by microdialysis in freely moving animals also did not differ between cocaine-kindled and control groups. Perfusion with the selective excitatory amino acid transporter inhibitor, pyrrolidine-2,4-dicarboxylic acid (tPDC, 0.6 mM), increased glutamate overflow confirming transport inhibition. Importantly, KCl-evoked glutamate overflow under tPDC perfusion was significantly higher in cocaine-kindled mice than in control mice. These data suggest that enhancement of depolarization stimulated glutamate release may be one of the mechanisms underlying the development of increased seizure susceptibility after cocaine kindling.

TI Impaired Ideomotor Limb Apraxia in Cortical and Subcortical Dementia: A Comparison of Alzheimer's and Huntington's Disease SO NEURODEGENERATIVE DISEASES LA English DT Article DE Huntington's disease; Alzheimer's disease; Apraxia; Neuropsychological assessment ID PROGRESSIVE SUPRANUCLEAR PALSY; PARKINSONS-DISEASE; IMITATING GESTURES; BASAL GANGLIA; MOTOR; CORTEX; PATHOPHYSIOLOGY; MOVEMENTS; PRAXIS; SCALE AB Background: Although ideomotor limb apraxia is often considered to occur only in dementia with cortical involvement like Alzheimer's disease (AD), it is also frequently seen in dementia with subcortical degeneration like Huntington's disease (HD). Methods: To assess the occurrence of ideomotor limb apraxia, 46 patients with HD (27 men) and 37 patients with AD (16 men), matched for cognitive performance, were assessed with an apraxia test battery containing tests of the imitation of meaningless hand and finger gestures, the performance of meaningful gestures and of pantomimic movements. Results: There was a high frequency of ideomotor limb apraxia in both AD and HD patients. For the assessment of hands' imitation 13.5% of the AD patients and 41.3% of the HD patients were apraxic, for fingers' imitation 21.6% (AD) and 41.3% (HD) were apraxic, for gestures 27.0% (AD) and 32.6% (HD), and for the assessment of pantomimic movements 24.3% (AD) and 52.2% (HD) showed apraxia. In the AD patients, disease severity was related to the occurrence of apraxia. Conclusions: Ideomotor limb apraxia is a common sign in both groups of patients, occurring in a high percentage. For particular neuropsychological deficits, including ideomotor limb apraxia, a division of dementia in a subcortical and cortical subtype seems to be clinically not meaningful. Copyright (C) 2011 S.

Recent genome-wide association studies (GWAS) have consistently linked several single nucleotide polymorphisms (SNPs) in the CHRNA3-CHRNA5-CHRNB4 cluster on chromosome 15.q25 to smoking behaviors and nicotine dependence. Investigations into these SNPs may help explain the nature and mechanisms of the smoking-PD relationship. Objective: To examine whether the genetic variations that were consistently associated with smoking or nicotine dependence in recent GWAS also predict the risk of PD. Methods: This is a population-based case-control study of 788 physician-diagnosed PD patients and 911 controls, all non-Hispanic Whites. Seven SNPs were selected based on findings from recent GWAS on smoking and nicotine dependence, all from the nicotinic acetylcholine receptor subunits (CHRN) A3-A5-B4. Odds ratios (ORs) and 95% confidence intervals were derived from logistic regression models under the assumption of logit-additive allelic effects. Results: Four SNPs in linkage disequilibrium from the CHRNA3-CHRNA5-CHRNB4 cluster were associated with smoking duration (OR >1.3, p < 0.05). However, none of the SNPs from this cluster was associated with PD risk in the overall analysis or after stratifying on smoking status. Conclusion: This preliminary analysis does not support a relationship between these smoking-related GWAS SNPs and PD. Copyright (C) 2011 S.

TI Lowering Corticosterone Levels Reinstates Hippocampal Brain-Derived Neurotropic Factor and Trkb Expression without Influencing Deficits in Hypothalamic Brain-Derived Neurotropic Factor Expression in Leptin Receptor-Deficient Mice SO NEUROENDOCRINOLOGY LA English DT Article DE Diabetes; Glucocorticoid; Neurotropic factor; Hippocampus; Hypothalamus ID SYNAPTIC PLASTICITY; DIABETIC MICE; OBESITY; BDNF; METABOLISM; NEURONS; MOUSE AB Background/Aims: Changes in the glucocorticoid milieu contribute to alterations in neurotropic factor expression across multiple brain regions. Insulin-resistant diabetes is often accompanied by dysregulation of adrenal steroid production in humans and animal models. Leptin receptor-deficient mice (db/db) show reduced expression of brain-derived neurotropic factor (BDNF) in the hippocampus and increases in circulating corticosterone levels, but the extent to which elevated corticosterone levels mediate deficits in BDNF expression has not been determined. Methods: Using in situ hybridization, we measured the expression of BDNF, its receptor TrkB, and neurotropin-3 (NT-3) in the hippocampus and hypothalamus of db/db mice and wild-type controls following adrenalectomy and low-dose corticosterone replacement (ADX+CORT) or sham operation. Results: Lowering corticosterone levels restored BDNF and TrkB expression in the hippocampus of db/db mice. However, deficits in hypothalamic BDNF expression were not reversed following ADX+CORT. There was no effect of genotype or adrenalectomy on NT-3 expression in any brain region examined. Conclusion: Leptin receptor-deficient mice exhibit reduced BDNF expression in the hippocampus and hypothalamus. In the db/db mouse hippocampus, suppression of BDNF occurs in a glucocorticoid-dependent fashion, while hypothalamic BDNF expression is reduced via glucocorticoid-independent mechanisms. Region-specific signals therefore play a role in the interaction between corticosteroids and neurotropic factor expression. Copyright (C) 2010 S.

We hypothesized that TSH level may reflect the degree of 'brain hypothyroidism' such that an inverse correlation may exist between serum TSH and cognitive function in patients experiencing overt hypothyroidism (OH), and sought to explore this hypothesis. METHODS: Eleven thyroidectomized patients underwent neuropsychological and thyroid function testing while overtly hypothyroid, and again following thyroid hormone replacement. Their test performance was compared with that of eleven healthy controls at a similarly separated two points in time, and the change over time for the patient group and the controls was likewise assessed and compared. The patients' neuropsychological test scores were then correlated with their serum TSH levels while hypothyroid. RESULTS: The patients' performance while hypothyroid was worse than that of the controls in only one neurocognitive measure - Working Memory Index. The subjects improved similarly or to a greater degree than the controls, when the subjects were thyroid hormone replaced, on all but one neurocognitive measure - Thurstone Word Fluency. TSH level during hypothyroidism was inversely proportional to the patients' performance on these same two measures, but no others. CONCLUSION: Serum TSH level during hypothyroidism was inversely proportional to performance on the only two neurocognitive measures evidencing an adverse effect from hypothyroidism in our cohort. This suggests thatserum TSH level may reflect the severity of 'brain hypothyroidism' during the overt stage of this condition.

Methods: Framingham Offspring Study participants, free of clinical stroke or dementia (n = 1,878; 60 +/- 9 years; 54% women), underwent neuropsychological assessment and ascertainment of 11 inflammatory markers. Follow-up neuropsychological assessments (6.3 +/- 1.0 years) were conducted on 1,352 of the original 1,878 participants. Results: Multivariable linear regression related the inflammatory markers to cross-sectional performance and longitudinal change in neuropsychological performances. Secondary models included a twelfth factor, tumor necrosis factor-alpha (TNF-alpha), available on a subset of the sample (n = 1,393 cross-sectional; n = 1,213 longitudinal). Results suggest a few modest cross-sectional inflammatory and neuropsychological associations, particularly for tests assessing visual organization (C-reactive protein, p = 0.007), and a few modest relations between inflammatory markers and neuropsychological change, particularly for executive functioning (TNF-alpha, p = 0.004). Secondary analyses suggested that inflammatory markers were cross-sectionally (TNF-alpha, p = 0.004) related to reading performance. Conclusions: Our findings are largely negative, but suggest that specific inflammatory markers may have limited associations with poorer cognition and reading performance among community-dwelling adults. Because of multiple testing concerns, our limited positive findings are offered as hypothesis generating and require replication in other studies. Copyright (C) 2011 S.

In 14 right-handed patients with writer's cramp, we employed VBM to test whether suppression (i.e., immobilization) or enhancement (i.e., training) of manual activity lead to opposing changes in grey matter in the contralateral primary motor hand area (M1(HAND)). We additionally used transcranial magnetic stimulation (TMS) to evaluate concurrent changes in regional excitability. Patients were recruited from a clinical trial which was designed to improve handwriting-associated dystonia. Initially the dystonic hand was immobilized for 4 weeks with the intention to reverse faulty plasticity. After immobilization, patients accomplished a motor re-training for 8 weeks. T1-weighted MRIs of the whole brain and single-pulse TMS measurements of the resting motor threshold (RMT) were performed every 4 weeks. Immobilization of the right hand resulted in a relative grey matter decrease in the contralateral left M1(HAND) along with a decrease in corticomotor excitability as indexed by an increase in RMT. Subsequent training reversed the effects of immobilization, causing an increase in regional grey matter density and excitability of left M1(HAND). The relative changes in grey matter correlated with the relative shifts in RMT. This prospective within-subject VBM study in task-specific hand dystonia shows that the grey matter density of M1(HAND) is dynamically shaped by the level of manual activity. This bi-directional structural plasticity is functionally relevant as local grey matter changes are mirrored by changes in regional excitability. (C) 2010 Elsevier Inc. All rights reserved.

TI Factors underlying prefrontal and insula structural alterations in smokers SO NEUROIMAGE LA English DT Article ID WHITE-MATTER INTEGRITY; NICOTINE DEPENDENCE; CIGARETTE-SMOKING; SPATIAL STATISTICS; COCAINE DEPENDENCE; GRAY-MATTER; MIDDLE-AGE; MR-IMAGES; IN-VIVO; DIFFUSION AB Based upon previous reports of alterations in white matter integrity and gray matter density in smokers, we examined these markers in a large, well-matched sample of smokers and non-smokers. We further investigated the effect of heavy cigarette exposure by using pack-years and the effects of two relatively stable, highly heritable traits in smokers (Fagerstrom Test of Nicotine Dependence (FIND), a measure of severity of nicotine dependence and Toronto Alexithymia Scale (TAS-20), a stable personality trait related to smoking). Forty-eight nicotine-dependent subjects and 48 matched controls were included in the analyses, with smokers also subdivided into high/low dependence and high/low pack-years smokers. White matter integrity (fractional anisotropy (FA)) and gray matter density (voxel-based morphometry (VBM)) were measured and compared across groups. Gray matter density was lower in left prefrontal cortex (PFC) in high pack-years smokers and was inversely related to pack-years. In contrast, left insular cortex gray matter density was higher in smokers and associated with TAS-20 total score and with difficulty-identifying-feelings factor. Further, the most highly dependent smokers showed lower prefrontal FA, which was negatively correlated with FEND. There was no correlation between pack-years and FIND in our smoker population. These data suggest chronic tobacco use is correlated with prefrontal gray matter damage, while differences in insula gray matter and PFC white matter appear to reflect stable and heritable differences between smokers and non-smokers.

However, the relationships between smoking cue-induced phasic activity and possible underlying differences in brain structure, tonic neuronal activity and connectivity between these brain areas are as yet unclear. Twenty-two smokers and 22 controls viewed smoking-related and neutral pictures during a functional arterial spin labeling scanning session. T1, resting functional, and diffusion tensor imaging data were also collected. Six brain areas, dorsal lateral prefrontal cortex (dIPFC), dorsal medial prefrontal cortex (dmPFC), dorsal anterior cingulate cortex/cingulate cortex, rostral anterior cingulate cortex (rACC), occipital cortex, and insula/operculum, showed significant smoking cue-elicited activity in smokers when compared with controls and were subjected to secondary analysis for resting state functional connectivity (rsFC). structural, and tonic neuronal activity. rsFC strength between rACC and dIPFC was positively correlated with the cue-elicited activity in dIPFC. Similarly, rsFC strength between dIPFC and dmPFC was positively correlated with the cue-elicited activity in dmPFC while rsFC strength between dmPFC and insula/operculum was negatively correlated with the cue-elicited activity in both dmPFC and insula/operculum, suggesting these brain circuits may facilitate the response to the salient smoking cues. Further, the gray matter density in dIPFC was decreased in smokers and correlated with cue-elicited activity in the same brain area, suggesting a neurobiological mechanism for the impaired cognitive control associated with drug use. Taken together, these results begin to address the underlying neurobiology of smoking cue salience, and may speak to novel treatment strategies and targets for therapeutic interventions.

Recent neuroscientific evidence on the activation of brain reward regions during altruistic punishment in two-person one-shot exchange games suggests satisfaction through the punishment of norm violations as one underlying motive. In order to address this issue in more detail, we used fMRI during a one-shot economic exchange game that warrants strong reciprocity by introducing a third party punishment condition wherein revenge is unlikely to play a role. We report here that indeed, reward regions such as the nucleus accumbens showed punishment-related activation. Moreover, we provide preliminary evidence that genetic variation of dopamine turnover impacts similarly on punishment-related nucleus accumbens activation during both first person and third party punishment. The overall pattern of results suggests a common cognitive-affective-motivational network as the driving force for altruistic punishment, with only quantitative differences between first person and third party perspectives.

Nanomedicine is the application of nanotechnology for the diagnosis and treatment of human disease. Disease-specific receptors on the surface of cells provide useful targets for nanoparticles. Because nanoparticles can be engineered from components that (1) recognize disease at the cellular level, (2) are visible on imaging studies, and (3) deliver therapeutic compounds, nanotechnology is well suited for the diagnosis and treatment of a variety of diseases. Nanotechnology will enable earlier detection and treatment of diseases that are best treated in their initial stages, such as cancer. Advances in nanotechnology will also spur the discovery of new methods for delivery of therapeutic compounds, including genes and proteins, to diseased tissue. A myriad of nanostructured drugs with effective site-targeting can be developed by combining a diverse selection of targeting, diagnostic, and therapeutic components. Incorporating immune target specificity with nanostructures introduces a new type of treatment modality, nano-immunochemotherapy, for patients with cancer. In this review, we will discuss the development and potential applications of nanoscale platforms in medical diagnosis and treatment. To impact the care of patients with neurological diseases, advances in nanotechnology will require accelerated translation to the fields of brain mapping, CNS imaging, and nanoneurosurgery. Advances in nanoplatform, nano-imaging, and nano-drug delivery will drive the future development of nanomedicine, personalized medicine, and targeted therapy. We believe that the formation of a science, technology, medicine law-healthcare policy (STML) hub/center, which encourages collaboration among universities, medical centers, US government, industry, patient advocacy groups, charitable foundations, and philanthropists, could significantly facilitate such advancements and contribute to the translation of nanotechnology across medical disciplines.

This includes production of neuroendocrine factors that alter immune system activity and increase susceptibility to or severity of immune-related conditions, such as myasthenia gravis (MG) - a T-cell-dependent, B-cell-mediated autoimmune disorder. MG results from impairment of transmission to the neuromuscular junction and involves the thymus - especially in early-onset disease, but the exact mechanism by which the thymus impacts disease is unclear. MG afflicts millions of individuals worldwide each year, and both men and women can develop symptoms. However, prevalence and age of onset differs between men and women. Women exhibit higher incidence and earlier age of onset compared to men, and disease fluctuates during pregnancy. This suggests that sex hormones play a role in influencing disease outcome. In this review, we will consider what is known about the manifestation of MG, theories on how different forms of MG are influenced or alleviated by steroid hormones, current treatment options, and what measures could be important to consider in the future.

As a result, there have been efforts to evaluate these compounds as leads for potential medication for cocaine addiction. Here we use computational modeling together with site-directed mutagenesis to characterize the binding site for BZTs in DAT. Docking into molecular models based on the structure of the bacterial homolog LeuT supported a BZT binding site that overlaps with the substrate-binding pocket. In agreement, mutations of residues within the pocket, including(2) Val152(3.46) to Ala or Ile, Ser422(8.60) to Ala and Asn157(3.51) to Cys or Ala, resulted in decreased affinity for BZT and the analog JHW007, as assessed in [(3)H]dopamine uptake inhibition assays and/or [(3)H] CFT competition binding assay. A putative polar interaction of one of the phenyl ring fluorine substituents in JHW007 with Asn157(3.51) was used as a criterion for determining likely binding poses and establish a structural context for the mutagenesis findings. The analysis positioned the other fluorine-substituted phenyl ring of JHW007 in close proximity to Ala479(10.51)/Ala480(10.52) in transmembrane segment (TM) 10. The lack of such an interaction for BZT led to a more tilted orientation, as compared to JHW007, bringing one of the phenyl rings even closer to Ala479(10.51)/Ala480(10.52). Mutation of Ala479(10.51) and Ala480(10.52) to valines supported these predictions with a larger decrease in the affinity for Bit than for JHW007. Summarized, our data suggest that BZTs display a classical competitive binding mode with binding sites overlapping those of cocaine and dopamine. (C) 2010 Elsevier Ltd. All rights reserved.

Continuation ECT (C-ECT) and maintenance ECT (M-ECT) are required for many patients suffering from severe and recurrent forms of mood disorders. This is a review of the literature regarding C- and M-ECT. Methods: We conducted a computerized search using the words continuation ECT, maintenance ECT, depression, mania, bipolar disorder and mood disorders. We report on all articles published in the English language from 1998 to 2009. Results: We identified 32 reports. There were 24 case reports and retrospective reviews on 284 patients. Two of these reports included comparison groups, and 1 had a prospective follow-up in a subset of subjects. There were 6 prospective naturalistic studies and 2 randomized controlled trials. Conclusions: C-ECT and M-ECT are valuable treatment modalities to prevent relapse and recurrence of mood disorders in patients who have responded to an index course of ECT. C-ECT and M-ECT are underused and insufficiently studied despite positive clinical experience of more than 70 years. Studies which are currently under way should allow more definitive recommendations regarding the choice, frequency and duration of C-ECT and M-ECT following acute ECT. Copyright (C) 2011 S.

We tested patients with Parkinson's disease (PD) with and without impulsive-compulsive behaviours (ICBs) and matched control subjects, on and off their regular dopamine replacement therapy on a task, in which the patients decided whether or not to invest a sum of money with a trustee. The sum was then quadrupled and the trustee could decide whether or not to return a portion of the investment. Participants could punish the trustee after they were informed of the trustee's decision. We found that PD patients without ICBs on or off medication punished more often than controls, whereas PD patients with ICBs punished more than controls on medication, but similar to controls off medication. These results suggest a role for dopamine in altruistic punishment decisions in PD patients with impulsive compulsive behaviour. Published by Elsevier Ltd.

Recent work has provided preclinical evidence indicating that TMS and tDCS can facilitate motor performance, motor memory formation, and motor skill learning in healthy subjects and possibly in patients with brain lesions. Although the optimal stimulation parameters to accomplish these goals remain to be determined, and controlled multicentre clinical studies are lacking, these findings suggest that cortical stimulation techniques could become in the future adjuvant strategies in the rehabilitation of motor deficits. The aim of this article is to critically review these findings and to discuss future directions regarding the possibility of combining these techniques with other interventions in neurorehabilitation.

This study examined whether cognitive complaints are associated with longitudinal changes in cognition and cross-sectional differences in regional brain function during memory performance in 98 participants with a mean age of 75. Method: The Cognitive Failures Questionnaire (CFQ) assessed cognitive complaints and mixed effects regression models were used to determine whether mean CFQ scores predicted rates of change in cognitive function over a period of 11.5 years. Results: Higher CFQ scores, reflecting increased subjective complaints, were associated with steeper rates of decline in immediate and delayed recall on the California Verbal Learning Test. Voxel-based regression analysis was used to determine the cross-sectional relationship between CFQ scores and regional cerebral blood flow measured by PET during a resting condition and during verbal and figural memory tasks. Higher levels of cognitive complaints were associated with increased activity in insular, lingual and cerebellar areas during memory tasks. Conclusions: These findings offer some support for the validity of subjective cognitive complaints as markers of age related changes in memory and brain activity.

This treatment is well grounded on controlled studies showing efficacy of low oral doses of methylphenidate and amphetamine in reducing the behavioral symptoms of the disorder as reported by parents and teachers, both for the cognitive (inattention and impulsivity) and noncognitive (hyperactivity) domains. Our main aim is to review the objectively measured cognitive effects that accompany the subjectively assessed clinical responses to stimulant medications. Recently, methods from the cognitive neurosciences have been used to provide information about brain processes that underlie the cognitive deficits of ADHD and the cognitive effects of stimulant medications. We will review some key findings from the recent literature, and then offer interpretations of the progress that has been made over the past decade in understanding the cognitive effects of stimulant medication on individuals with ADHD.

In rats, the anxiogenic drug yohimbine, which causes stress-like responses in both humans and nonhumans, reinstates food seeking in a relapse model. In this study, we examined the role of medial prefrontal cortex (mPFC) dopamine D1-family receptors, previously implicated in stress-induced reinstatement of drug seeking, in yohimbine-induced reinstatement of food seeking. We trained food-restricted rats to lever press for 35% high-fat pellets every other day (9-15 sessions, 3 h each); pellet delivery was accompanied by a discrete tone-light cue. We then extinguished operant responding for 10-16 days by removing the pellets. Subsequently, we examined the effect of yohimbine (2 mg/kg, i.p.) on reinstatement of food seeking and Fos (a neuronal activity marker) induction in mPFC. We then examined the effect of systemic injections of the D1-family receptor antagonist SCH23390 (10 mu g/kg, s.c.) on yohimbine-induced reinstatement and Fos induction, and that of mPFC SCH23390 (0.5 and 1.0 mu g/side) injections on this reinstatement. Yohimbine-induced reinstatement was associated with strong Fos induction in the dorsal mPFC and with weaker Fos induction in the ventral mPFC. Systemic SCH23390 injections blocked both yohimbine-induced reinstatement and mPFC Fos induction. Dorsal, but not ventral, mPFC injections of SCH23390 decreased yohimbine-induced reinstatement of food seeking. In addition, dorsal mPFC SCH23390 injections decreased pellet-priming-induced reinstatement, but had no effect on ongoing high-fat pellet self-administration or discrete-cue-induced reinstatement. Results indicate a critical role of dorsal mPFC dopamine D1-family receptors in stress-induced relapse to palatable food seeking, as well as relapse induced by acute re-exposure to food taste, texture, and smell.

In this review we will summarize the main technical and methodological considerations that are necessary when using TMS in cognitive neuroscience, based on a corpus of studies and technical improvements that has become available in most recent years. Although TMS has been applied only relatively recently on a large scale to the study of higher functions, a range of protocols that elucidate how this technique can be used to investigate a variety of issues is already available, such as single pulse, paired pulse, dual-site, repetitive and theta burst TMS. Finally, we will touch on recent promising approaches that provide powerful new insights about causal interactions among brain regions (i.e., TMS with other neuroimaging techniques) and will enable researchers to enhance the functional resolution of TMS (i.e., state-dependent TMS). We will end by briefly summarizing and discussing the implications of the newest safety guidelines. (C) 2010 Elsevier Ltd. All rights reserved.

Herein, we have investigated the interplay between microglia and human NM on the degeneration of SN dopaminergic neurons. Although NM particles are phagocytized and degraded by microglia within minutes in vitro, extracellular NM particles induce microglial activation and ensuing production of superoxide, nitric oxide, hydrogen peroxide (H(2)O(2)), and pro-inflammatory factors. Furthermore, NM produces, in a microglia-depended manner, neurodegeneration in primary ventral midbrain cultures. Neurodegeneration was effectively attenuated with microglia derived from mice deficient in macrophage antigen complex-1, a microglial integrin receptor involved in the initiation of phagocytosis. Neuronal loss was also attenuated with microglia derived from mice deficient in phagocytic oxidase, a subunit of NADPH oxidase, that is responsible for superoxide and H(2)O(2) production, or apocynin, an NADPH oxidase inhibitor. In vivo, NM injected into rat SN produces microgliosis and a loss of tyrosine hydroxylase neurons. Thus, these results show that extracellular NM can activate microglia, which in turn may induce dopaminergic neurodegeneration in PD. Our study may have far-reaching implications, both pathogenic and therapeutic.

NeuroAIDS is characterized by neuronal injury and loss, yet there is no evidence of HIV infection in neurons. Thus, neuronal damage and dropout are likely due to indirect effects of HIV infection of other CNS cells, through elaboration of inflammatory factors and neurotoxic viral proteins, including the viral transactivating protein tat. We and others demonstrated that tat induces apoptosis in differentiated mature human neurons. We now demonstrate that the high level of tat toxicity observed in human neurons involves specific developmental stages that correlate with N-Methyl-D-Aspartate receptor (NMDAR) expression, and that tat toxicity is also dependent upon the species being analyzed. Our results indicate that tat treatment of primary cultures of differentiated human neurons with significant amounts of NMDAR expression induces extensive apoptosis. In contrast, tat treatment induces only low levels of apoptosis in primary cultures of immature human neurons with low or minimal expression of NMDAR. In addition, tat treatment has minimal effect on rat hippocampal neurons in culture, despite their high expression of NMDAR. We propose that this difference may be due to low expression of the NR2A subunit. These findings are important for an understanding of the many differences among tissue culture systems and species used to study HIV-tat-mediated toxicity. C1 [Eugenin, E. A.; King, J.

However, these behavior problems may not manifest in a structured environment, such as a school setting. Objective: We determined whether there is an association between PCE and school behavior problems and whether ratings of behavior problems from the teacher differ from those noted by the parent or caretaker. Methods: The Maternal Lifestyle Study, a multicenter study, enrolled 1388 children with and without PCE at one month of age for longitudinal assessment Teachers masked to prenatal drug exposure status completed the Teacher Report Form (TRF/6-18) when children were 7, 9, and 11 years old. We also administered the Child Behavior Checklist-parent report (CBCL) to the parent/caretaker at same ages and then at 13 years. We performed latent growth curve modeling to determine whether high PCE will predict externalizing, internalizing, total behavior, and attention problems at 7 years of age and whether changes in problems' scores over time differ between those exposed and non-exposed from both teacher and parent report. Besides levels of PCE as predictors, we controlled for the following covariates, namely: site, child characteristics (gender and other prenatal drug exposures), family level influences (maternal age, depression and psychological symptomatology, continuing drug use, exposure to domestic violence, home environment and socioeconomic status), and community level factors (neighborhood and community violence). Results: The mean behavior problem T scores from the teacher report were significantly higher than ratings by the parent or caretaker. Latent growth curve modeling revealed a significant relationship between intercepts of problem T scores from teacher and parent ratings; i.e., children that were rated poorly by teachers were also rated poorly by their parent/caretaker or vice versa. After controlling for covariates, we found high PCE to be a significant predictor of higher externalizing behavior problem T scores from both parent and teacher report at 7 years (p = 0.034 and p = 0.021, respectively) in comparison to non-PCE children. These differences in scores from either teacher or caregiver were stable through subsequent years or did not change significantly over time. Boys had higher T scores than girls on internalizing and total problems by caretaker report; they also had significantly higher T scores for internalizing, total, and attention problems by teacher ratings; the difference was marginally significant for externalizing behavior (p = 0.070). Caretaker postnatal use of tobacco, depression, and community violence were significant predictors of all behavior problems rated by parent/caretaker, while lower scores on the home environment predicted all behavior outcomes by the teacher report. Conclusions: Children with high PCE are likely to manifest externalizing behavior problems; their behavior problem scores at 7 years from either report of teacher or parent remained higher than scores of non-exposed children on subsequent years. Screening and identification of behavior problems at earlier ages could make possible initiation of intervention, while considering the likely effects of other confounders. (C) 2010 Elsevier Inc.

To date, no published human studies have evaluated the relation between prenatal cocaine exposure and postnatal adolescent cocaine use. Human studies of prenatal cocaine-exposed children have also noted an increase in behaviors previously associated with substance use/abuse in teens and young adults, specifically childhood and teen externalizing behaviors, impulsivity, and attention problems. Despite these findings, human research has not addressed prior prenatal exposure as a potential predictor of teen drug use behavior. The purpose of this study was to evaluate the relations between prenatal cocaine exposure and teen cocaine use in a prospective longitudinal cohort (n = 316) that permitted extensive control for child, parent and community risk factors. Logistic regression analyses and Structural Equation Modeling revealed that both prenatal exposure and postnatal parent/caregiver cocaine use were uniquely related to teen use of cocaine at age 14 years. Teen cocaine use was also directly predicted by teen community violence exposure and caregiver negativity, and was indirectly related to teen community drug exposure. These data provide further evidence of the importance of prenatal exposure, family and community factors in the intergenerational transmission of teen/young adult substance abuse/use.

In this paper we aim to elucidate exposure related behavioral phenotypes and developmental pathways by testing: (a) differential associations of exposure and four disruptive behavior dimensional phenotypes: Aggression, Noncompliance, Temper Loss and Low Concern for Others; and (b) moderation of these pathways including sex differences and moderation by parental responsive engagement. Participants were 211 teens and their parents from the East Boston Family Study (EBFS), an adolescent follow-up of a pregnancy cohort over-sampled for exposure. A best estimate serum cotinine corrected score was used to characterize exposure. In multivariate models controlling for parental antisocial behavior, family adversity and secondhand exposure, exposure uniquely predicted Aggression and Noncompliance. Paternal responsiveness moderated exposure effects on disruptive behavior. There were no sex differences in these patterns. Phenotypic findings suggest the possibility of specific neural mechanisms. In conjunction with prior research, protective effects of parental responsiveness occurring as late as adolescence point to the potential benefit of parenting-based prevention efforts to reduce risk to exposed offspring.

Design: The prospective, controlled longitudinal Infant Development, Environment and Lifestyle (IDEAL) study of prenatal MA exposure from birth to 36 months was conducted in the US and NZ. The US cohort has 183 exposed and 196 comparison infants; the NZ cohort has 85 exposed and 95 comparison infants. Exposure was determined by self-report and meconium assay with alcohol, marijuana, and tobacco exposures present in both groups. The NICU Neurobehavior Scale (NNNS) was administered within 5 days of life. NNNS summary scores were analyzed for exposure including heavy exposure and frequency of use by trimester and dose-response relationship with the amphetamine analyte. Results: MA exposure was associated with poorer quality of movement, more total stress/abstinence, physiological stress, and CNS stress with more nonoptimal reflexes in NZ but not in the USA. Heavy MA exposure was associated with lower arousal and excitability. First trimester MA use predicted more stress and third trimester use more lethargy and hypotonicity. Dose-response effects were observed between amphetamine concentration in meconium and CNS stress. Conclusion: Across cultures, prenatal MA exposure was associated with a similar neurobehavioral pattern of under arousal, low tone, poorer quality of movement and increased stress.

TI Motor and cognitive outcomes through three years of age in children exposed to prenatal methamphetamine SO NEUROTOXICOLOGY AND TERATOLOGY LA English DT Article DE Prenatal exposure; Neurodevelopment; Bayley; Peabody ID MATERNAL LIFE-STYLE; COCAINE EXPOSURE; IN-UTERO; INFANT DEVELOPMENT; INTRAUTERINE GROWTH; RAT PUPS; PREGNANCY; AMPHETAMINE; ENVIRONMENT; TERM AB Background: Methamphetamine (MA) use among pregnant women is an increasing problem in the United States. The impact of prenatal MA exposure on development in childhood is unknown. Objective: To examine the effects of prenatal MA exposure on motor and cognitive development in children at 1, 2, and 3 years of age. Design/methods: IDEAL enrolled 412 mother-infant pairs at four sites (Tulsa OK, Des Moines IA, Los Angeles CA, and Honolulu HI). MA subjects (n = 204) were identified by self report or GC/MS confirmation of amphetamine and metabolites in infant meconium. Comparison subjects (n = 208) were matched (race, birth weight, maternal education, and type of insurance), denied amphetamine use, and had a negative meconium screen. Both groups included prenatal alcohol, tobacco and marijuana use, but excluded use of opiates, lysergic acid diethylamide, phencyclidine or cocaine only. The Peabody Developmental Motor Scales (PDMS-2) were administered to the infants at the 1 and 3 year visits. This analysis includes a subsample (n = 350) of the IDEAL study with completed 1 and/or 3 year visits (n = 330 and 281, respectively). At each annual visit we also conducted the Bayley Scales of Infant Development (BSID-II) as a general evaluation of mental and motor development. The BSID-II analysis includes a subsample (n = 356) of the IDEAL study with completed 1, 2, and/or 3 year visits (n = 331, 288, and 278 respectively). GLM analysis conducted on the PDMS-2 and BSID-II examined the effects of MA exposure and heavy MA exposure (>= 3 days of use/week), with and without covariates. Longitudinal analyses were used to examine the effects of MA exposure on changes in motor and cognitive performance over time. Results: Heavy MA exposure was associated with significantly lower grasping scores than some and no use at 1 year (P = 0.018). In longitudinal analysis, lower grasping scores associated with any MA exposure and heavy exposure persisted to 3 years. There were no effects of MA exposure, including heavy exposure, on the Bayley Mental Development Index (MDI) or Psychomotor Development Index (PDI) at any or across age. Conclusions: There were no differences in cognition as assessed by the BSID-II between the groups. There was a subtle MA exposure effect on fine motor performance at 1 year with the poorest performance observed in the most heavily exposed children. By 3 years, no differences in fine motor performance were observed. These findings suggest MA exposure has modest motor effects at 1 year that are mostly resolved by 3 years. (C) 2010 Elsevier Inc.

Methods: 655 women underwent standardized preoperative UDS that included perineal surface EMG prior to undergoing surgery for stress urinary incontinence. Pressure-flow studies were evaluated for abdominal straining and interrupted flow. Quantitative EMG values were extracted from 10 predetermined time-points and compared between fill and void. Qualitative EMG activity was assessed for the percent of time EMG was active during fill and void and for the average amplitude of EMG during fill compared to void. Postoperative voiding dysfunction was defined as surgical revision or catheterization more than 6 weeks after surgery. Fisher's exact test with a 5% two-sided significance level was used to assess differences in EMG activity and postoperative voiding dysfunction. Results: 321 UDS had interpretable EMG studies, of which 131 (41%) had EMG values at all 10 predetermined and annotated time-points. Quantitative and qualitative EMG signals during flow were usually greater than during fill. The prevalence of postoperative voiding dysfunction in subjects with higher preoperative EMG activity during void was not significantly different. Results were similar in the 42 subjects who had neither abdominal straining during void nor interrupted flow. Conclusions: Perineal surface patch EMG did not measure expected pelvic floor and urethral sphincter relaxation during voiding. Preoperative EMG did not predict patients at risk for postoperative voiding dysfunction. Neurourol. Urodynam. 30:1591-1596, 2011. (C) 2011 Wiley Periodicals, Inc.

If emotions are not natural kinds, there will be widespread consequences for the theoretical foundations of behavioral neuroscience and grave implications for the validity of animal models of emotion and affective disorders. This paper presents the evidence against the hypothesis of emotions as natural kinds, and offers the "domain-interplay" concept as a novel and effective experimental method for establishing the theoretical rationale of non-human animal research in the neurosciences.

However, because of the low levels of s-nitrosothiols and interference with other nitric oxide species, reliable assays that measure both high molecular weight and low molecular weight s-nitrosothiols in plasma and red blood cells have been difficult to develop. We have previously developed a sensitive method using Cu(II)-ascorbic acid at a neutral pH, which was specific for s-nitrosothiols without interference of nitrite or other NOx species. However, due to neutral pH foaming, this method was not suitable for determinations in plasma or red blood cells with high protein content. This method has now been modified by using copper (II) chloride (CuCl2) and ascorbic acid in glacial acetic acid. The low pH solves the foaming problem. However, protonation of nitrite under acidic conditions facilitates the formation of s-nitrosothiols. For this method to specifically measure s-nitrosothiols in the sample, the unreacted thiols are blocked by reacting with N-ethylmaleimide and nitrite is blocked by reacting with acidified sulfanilamide before being analyzed by chemiluminescence. Using this method, s-nitrosothiols have been determined in the range of 2 nM to 26 nM (mean +/- SE = 10.18 +/- 2.1) in plasma and up to 88.1 nM (mean +/- SE = 51.27 +/- 10.5) in red blood cells.

Therefore, assessing nitrite levels in various organs and compartments is an important issue. As nitrite levels in most organs and tissues ate low (in high nanomolar or low micromolar range) several new sensitive methods for quantifying nitrite in various biological samples have been developed. Chemiluminescence, combined with triiodide reducing solution, is currently considered the most sensitive method, allowing quantification in the low nanomolar range of nitrite concentrations. Here, we present an overview of chemiluminescence-based determination of nitrite in blood and blood compartments red blood cells and plasma. We also explain how to preserve the original physiological nitrite concentration in nitrite-hostile environments, such as an excess of hemoglobin in blood.

This chapter reviews key characteristics of nitrogen-fixing genomes and methods to identify and analyze genomes of new diazotrophs using genome scanning. This chapter refers to Azotobacter vinelandii, a well-studied nitrogen-fixing organism, as a model for studying nitrogen-fixing genomes. We discuss the main nitrogen fixation genes as well as accessory genes that contribute to diazotrophy. We also review approaches that can be used to modify genomes in order to study nitrogen fixation at the genetic, biochemical, and biophysical level.

Because of its shortening of T-1 and its relatively long half-life in cells, Mn2+ can serve as an intracellular molecular contrast agent to study indirect calcium influx into the myocardium. One major concern in using Mn2+ is its sensitivity over a limited range of concentrations employing T-1-weighted images for visualization, which limits its potential in quantitative techniques. Therefore, this study assessed the implementation of a T-1 mapping method for cardiac manganese-enhanced MRI to enable a quantitative estimate of the influx of Mn2+ over a wide range of concentrations in male Sprague-Dawley rats. This MRI method was used to compare the relationship between T-1 changes in the heart as a function of myocardium and blood Mn2+ levels. Results showed a biphasic relationship between Delta R-1 and the total Mn2+ infusion dose. Nonlinear relationships were observed between the total Mn2+ infusion dose versus blood levels and left ventricular free wall Delta R-1. At low blood levels of Mn2+, there was proportionally less cardiac enhancement seen than at higher levels of blood Mn2+. We hypothesize that Mn2+ blood levels increase as a result of rate-limiting excretion by the liver and kidneys at these higher Mn2+ doses. Copyright (C) 2010 John Wiley & Sons, Ltd.

Sequence-specific DNA binding is essential for p53-mediated tumor suppression. We evaluated the impact of single-nucleotide polymorphisms (SNPs) in p53 response elements (p53RE) on DNA binding and gene expression in response to DNA damage. Using a bioinformatics approach based on incorporating p53 binding strength into a position weight matrix, we selected 32 SNPs in putative and validated p53REs. The microsphere assay for protein-DNA binding (MAPD) and allele-specific expression analysis was employed to assess the impact of SNPs on p53-DNA binding and gene expression, respectively. Comparing activated p53 binding in nuclear extracts from doxorubicin- or ionizing radiation (IR)-treated human cells, we observed little difference in binding profiles. Significant p53 binding was observed for most polymorphic REs and several displayed binding comparable to the p21 RE. SNP alleles predicted to lower p53 binding indeed reduced binding in 25 of the 32 sequences. Chromatin immunoprecipitation-sequencing in lymphoblastoid cells confirmed p53 binding to seven polymorphic p53 REs in response to doxorubicin. In addition, five polymorphisms were associated with altered gene expression following doxorubicin treatment. Our findings demonstrate an effective strategy to identify and evaluate SNPs that may alter p53-mediated stress responses.

More recent studies have shown that the enzyme also plays an important role during the establishment of invasive infections by degrading extracellular chromatin in the form of neutrophil extracellular traps (NETs), enabling streptococci to overcome the innate immune system in mammals. As a virulence factor, EndA has become an interesting target for future drug design. Here we present the first mutational and biochemical analysis of recombinant forms of EndA produced either in a cell-free expression system or in Escherichia coli. We identify His160 and Asn191 to be essential for catalysis and Asn182 to be required for stability of EndA. The role of His160 as the putative general base in the catalytic mechanism is supported by chemical rescue of the H160A variant of EndA with imidazole added in excess. Our study paves the way for the identification and development of protein or low-molecular-weight inhibitors for EndA in future high-throughput screening assays.

The original objective of GEO was to serve as a public repository for high-throughput gene expression data generated mostly by microarray technology. However, the research community quickly applied microarrays to non-gene-expression studies, including examination of genome copy number variation and genome-wide profiling of DNA-binding proteins. Because the GEO database was designed with a flexible structure, it was possible to quickly adapt the repository to store these data types. More recently, as the microarray community switches to next-generation sequencing technologies, GEO has again adapted to host these data sets. Today, GEO stores over 20 000 microarray- and sequence-based functional genomics studies, and continues to handle the majority of direct high-throughput data submissions from the research community. Multiple mechanisms are provided to help users effectively search, browse, download and visualize the data at the level of individual genes or entire studies. This paper describes recent database enhancements, including new search and data representation tools, as well as a brief review of how the community uses GEO data. GEO is freely accessible at http://www.ncbi.nlm.nih.gov/geo/.

In order to provide access to genome-wide locations of these classes of predicted structures, we have developed non-B DB, a database integrating annotations and analysis of non-B DNA-forming sequence motifs. The database provides the most complete list of alternative DNA structure predictions available, including Z-DNA motifs, quadruplex-forming motifs, inverted repeats, mirror repeats and direct repeats and their associated subsets of cruciforms, triplex and slipped structures, respectively. The database also contains motifs predicted to form static DNA bends, short tandem repeats and homo(purine center dot pyrimidine) tracts that have been associated with disease. The database has been built using the latest releases of the human, chimp, dog, macaque and mouse genomes, so that the results can be compared directly with other data sources. In order to make the data interpretable in a genomic context, features such as genes, single-nucleotide polymorphisms and repetitive elements (SINE, LINE, etc.) have also been incorporated. The database is accessed through query pages that produce results with links to the UCSC browser and a GBrowse-based genomic viewer. It is freely accessible at http://nonb.abcc.ncifcrf.gov.

TI NCBI Epigenomics: a new public resource for exploring epigenomic data sets SO NUCLEIC ACIDS RESEARCH LA English DT Article ID EPIGENETIC INHERITANCE; CANCER; CHROMATIN; GENOME AB The Epigenomics database at the National Center for Biotechnology Information (NCBI) is a new resource that has been created to serve as a comprehensive public resource for whole-genome epigenetic data sets Epigenetics is the study of stable and heritable changes in gene expression that occur independently of the primary DNA sequence. Epigenetic mechanisms include post-translational modifications of histones, DNA methylation, chromatin conformation and non-coding RNAs. It has been observed that misregulation of epigenetic processes has been associated with human disease. We have constructed the new resource by selecting the subset of epigenetics-specific data from general-purpose archives, such as the Gene Expression Omnibus, and Sequence Read Archives, and then subjecting them to further review, annotation and reorganization. Raw data is processed and mapped to genomic coordinates to generate 'tracks' that are a visual representation of the data. These data tracks can be viewed using popular genome browsers or downloaded for local analysis. The Epigenomics resource also provides the user with a unique interface that allows for intuitive browsing and searching of data sets based on biological attributes. Currently, there are 69 studies, 337 samples and over 1100 data tracks from five well-studied species that are viewable and downloadable in Epigenomics.

The preservation of experimental data is an important part of the scientific record, and increasing numbers of journals and funding agencies require that next-generation sequence data are deposited into the SRA. The SRA was established as a public repository for the next-generation sequence data and is operated by the International Nucleotide Sequence Database Collaboration (INSDC). INSDC partners include the National Center for Biotechnology Information (NCBI), the European Bioinformatics Institute (EBI) and the DNA Data Bank of Japan (DDBJ). The SRA is accessible at http://www.ncbi.nlm.nih.gov/Traces/sra from NCBI, at http://www.ebi.ac.uk/ena from EBI and at http://trace.ddbj.nig.ac.jp from DDBJ. In this article, we present the content and structure of the SRA, detail our support for sequencing platforms and provide recommended data submission levels and formats.

TI CDD: a Conserved Domain Database for the functional annotation of proteins SO NUCLEIC ACIDS RESEARCH LA English DT Article ID GENOMES; SEARCH AB NCBI's Conserved Domain Database (CDD) is a resource for the annotation of protein sequences with the location of conserved domain footprints, and functional sites inferred from these footprints. CDD includes manually curated domain models that make use of protein 3D structure to refine domain models and provide insights into sequence/structure/function relationships. Manually curated models are organized hierarchically if they describe domain families that are clearly related by common descent. As CDD also imports domain family models from a variety of external sources, it is a partially redundant collection. To simplify protein annotation, redundant models and models describing homologous families are clustered into superfamilies. By default, domain footprints are annotated with the corresponding superfamily designation, on top of which specific annotation may indicate high-confidence assignment of family membership. Pre-computed domain annotation is available for proteins in the Entrez/Protein dataset, and a novel interface, Batch CD-Search, allows the computation and download of annotation for large sets of protein queries. CDD can be accessed via http://www.ncbi.nlm.nih.gov/Structure/cdd/cdd.shtml.

The updated DOMINE includes 2285 new domain-domain interactions (DDIs) inferred from experimentally characterized high-resolution three-dimensional structures, and about 3500 novel predictions by five computational approaches published over the last 3 years. These additions bring the total number of unique DDIs in the updated version to 26 219 among 5140 unique Pfam domains, a 23% increase compared to 20 513 unique DDIs among 4346 unique domains in the previous version. The updated version now contains 6634 known DDIs, and features a new classification scheme to assign confidence levels to predicted DDIs. DOMINE will serve as a valuable resource to those studying protein and domain interactions. Most importantly, DOMINE will not only serve as an excellent reference to bench scientists testing for new interactions but also to bioinformaticans seeking to predict novel protein-protein interactions based on the DDIs.

Deficiencies in FEN1 function or deletion of the fen1 gene have profound biological effects, including the suppression of repair of DNA damage incurred from the action of various genotoxic agents. Given the importance of FEN1 in resolving abnormal DNA structures, inhibitors of the enzyme carry a potential as enhancers of DNA-interactive anticancer drugs. To facilitate the studies of FEN1 activity and the search for novel inhibitors, we developed a pair of complementary-readout homogeneous assays utilizing fluorogenic donor/quencher and AlphaScreen chemiluminescence strategies. A previously reported FEN1 inhibitor 3-hydroxy-5-methyl-1-phenylthieno[2,3-d]pyrimidine-2,4(1H,3H)-dione displayed equal potency in the new assays, in agreement with its published IC(50). The assays were optimized to a low 4 mu l volume and used to investigate a set of small molecules, leading to the identification of previously-unreported FEN1 inhibitors, among which aurintricarboxylic acid and NSC-13755 (an arylstibonic derivative) displayed submicromolar potency (average IC(50) of 0.59 and 0.93 mu M, respectively). The availability of these simple complementary assays obviates the need for undesirable radiotracer-based assays and should facilitate efforts to develop novel inhibitors for this key biological target.

Supported by emerging evidence from in vitro and animal studies, these reports suggest that brain hypometabolism may precede and therefore contribute to the neuropathologic cascade leading to cognitive decline in AD. The reason brain hypometabolism develops is unclear but may include defects in brain glucose transport, disrupted glycolysis, and/or impaired mitochondrial function. Methodologic issues presently preclude knowing with certainty whether or not aging in the absence of cognitive impairment is necessarily associated with lower brain glucose metabolism. Nevertheless, aging appears to increase the risk of deteriorating systemic control of glucose utilization, which, in turn, may increase the risk of declining brain glucose uptake, at least in some brain regions. A contributing role of deteriorating glucose availability to or metabolism by the brain in AD does not exclude the opposite effect, i.e., that neurodegenerative processes in AD further decrease brain glucose metabolism because of reduced synaptic functionality and hence reduced energy needs, thereby completing a vicious cycle. Strategies to reduce the risk of AD by breaking this cycle should aim to (1) improve insulin sensitivity by improving systemic glucose utilization, or (2) bypass deteriorating brain glucose metabolism using approaches that safely induce mild, sustainable ketonemia.

High-temperature cooking methods such as grilling and barbecuing may produce heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which are known carcinogens. We assessed the association with meat consumption and estimated HCA and PAH exposure in a population-based case-control study of prostate cancer. Newly diagnosed cases aged 40-79 years (531 advanced cases, 195 localized cases) and 527 controls were asked about dietary intake, including usual meat cooking methods and doneness levels. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariate logistic regression. For advanced prostate cancer, but not localized disease, increased risks were associated with higher consumption of hamburgers (OR = 1.79, CI = 1.10-2.92), processed meat (OR = 1.57, CI = 1.04-2.36), grilled red meat (OR = 1.63, CI = 0.99-2.68), and well-done red meat (OR = 1.52, CI = 0.93-2.46), and intermediate intake of 2-amino-1-methyl1-6-phenylimidazo[4,5-b]pyridine (PhIP) (Quartile 2 vs. 1: OR = 1.41, CI = 0.98-2.01; Quartile 3 vs. 1: OR = 1.42, CI = 0.98-2.04), but not for higher intake. White meat consumption was not associated with prostate cancer. These findings provide further evidence that consumption of processed meat and red meat cooked at high temperature is associated with increased risk of advanced, but not localized, prostate cancer.

METHODS: Blood for DNA analysis was collected from 834 women at high risk enrolled in a randomized, clinical trial of omega-3 fatty acid supplementation for the prevention of recurrent preterm birth. Genotyping was performed for three single nucleotide polymorphisms (SNPs), TNF-alpha -308, IL-6 -174, and IL-1 beta +3954. Women with the homozygous minor genotype were compared with women with either the heterozygous or the homozygous major genotype. Kaplan-Meier curves of gestational age at delivery and odds ratios for extreme preterm delivery were adjusted for African-American race and treatment group. RESULTS: Women who were homozygous for the minor allele at the -308 position in the promoter region of the TNF-alpha gene had significantly shorter length of gestation than women who were either heterozygous or homozygous for the major allele (adjusted hazard ratio 1.74, 95% confidence interval [CI] 1.04-2.90, P=.03). Among women with this genotype, 20% (3/15) experienced extreme spontaneous preterm delivery (less than 28 weeks of gestation; adjusted odds ratio 7.51, 95% CI 1.84-30.72, P=.005). There was no difference in length of gestation or risk of extreme spontaneous preterm delivery by genotype for the IL-6 -174 or the IL-1 beta +3954 SNP. CONCLUSION: Polymorphism at the -308 position in the TNF-alpha promoter region is associated with shorter gestation and an increased risk of spontaneous extreme preterm delivery.

Expert assessment of detailed work history data is usually considered the best approach, but it is a laborious and time-consuming process. We set out to determine if a less intensive method of exposure assessment (a job exposure matrix (JEM)) would produce similar results to a previous analysis that found evidence of effect modification of the association between expert-assessed lead exposure and risk of brain tumours by a single nucleotide polymorphism in the ALAD gene (rs1800435). Methods We used data from a study of 355 patients with glioma, 151 patients with meningioma and 505 controls. Logistic regression models were used to examine associations between brain tumour risk and lead exposure and effect modification by genotype. We evaluated Cohen's kappa, sensitivity and specificity for the JEM compared to the expert-assessed exposure metrics. Results Although effect estimates were imprecise and driven by a small number of cases, we found evidence of effect modification between lead exposure and ALAD genotype when using expert-but not JEM-derived lead exposure estimates. kappa Values indicated only modest agreement (<0.5) for the exposure metrics, with the JEM indicating high specificity (similar to 0.9) but poor sensitivity (similar to 0.5). Disagreement between the two methods was generally due to having additional information in the detailed work history. Conclusion These results provide preliminary evidence suggesting that high quality exposure data are likely to improve the ability to detect genetic effect modification.

KS development is highly favored by immune-depression and remains the second most frequent tumor in acquired immune deficiency syndrome patients. Although it has been shown that experimental expression of the HHV8 G-protein-coupled receptor (vGPCR) in the endothelial compartment is alone sufficient to recapitulate the formation and progression of KS-like lesions, its functional effects on endothelial homeostasis are not fully understood. Here we show that vGPCR expression in endothelial cells induces an increase in paracellular permeability both in vivo and in vitro. By using pharmacological inhibitors and small interference RNA-based knockdown, we demonstrate an essential role for the PI(3)Kinase-gamma/Rac nexus in vGPCR-mediated permeability. This was further accompanied by dramatic remodeling of VE-cadherin-dependent cell-cell junctions. Importantly, this in vitro vGPCR-initiated signaling signature was observed in a large panel of human KS. Altogether, our results support the hypothesis that endothelial vGPCR signaling is co-opted in KS, and unveil new key cellular targets for therapeutic intervention.

However, little is known of the tumorigenic function of PAUF. In this study, we report the X-ray crystal structure of PAUF and reveal that PAUF is a mammalian lectin normally found in plant lectins. We also identify PAUF as an endogenous ligand of Toll-like receptor 2 (TLR2) and TLR4 by screening extracellular domain receptor pools. We further confirmed the specificity of the PAUF-TLR2 interaction. PAUF induces extracellular signal-regulated kinase (ERK) phosphorylation and activates the IKK-beta-mediated TPL2/MEK/ERK signaling pathway through TLR2. In agreement with the result of TLR2-mediated ERK activation by PAUF, PAUF induces increased expression of the protumorigenic cytokines RANTES and MIF in THP-1 cells. However, PAUF does not fully activate I kappa-B-alpha signaling pathways in THP-1 cells, and fails to translocate the p65 subunit of the nuclear factor-kappa B (NF-kappa B) complex into the nucleus, resulting in no NF-kappa B activation. Surprisingly, we found that PAUF also associated with the CXC chemokine receptor (CXCR4)-TLR2 complex and inhibited CXCR4-dependent, TLR2-mediated NF-kappa B activation. Together, these findings suggest that the new cancer-associated ligand, PAUF, may activate TLR-mediated ERK signaling to produce the protumorigenic cytokines, but inhibits TLR-mediated NF-kappa B signaling, thereby facilitating tumor growth and escape from innate immune surveillance.

Previously identified as an oncogene, its mutation or overexpression is reported in a variety of human cancers. To address its role in skin carcinogenesis, Tpl2(-/-) or wild-type (WT) C57BL/6 mice were subjected to a two-stage dimethylbenzanthracene/12-O-tetradecanoylphorbol- 13-acetate (TPA) mouse skin carcinogenesis model. Tpl2(-/-) mice developed a significantly higher incidence of tumors (80%) than WT mice (17%), as well as a reduced tumor latency and a significantly higher number of total tumors (113 vs 6). Moreover, Tpl2(-/-) mice treated with TPA experienced significantly higher nuclear factor kappaB (NF-kappa B) activation, edema, infiltrating neutrophils and production of proinflammatory cytokines than did WT mice. We investigated the role of the p38, JNK, MEK and NF-kappa B signaling pathways both in vitro and in vivo in WT and Tpl2(-/-) mice by using inhibitors for each of these pathways. We confirmed that the proinflammatory effect in Tpl2(-/-) mice was due to heightened activity of the NF-kappa B pathway. These studies indicate that Tpl2 may serve more as a tumor suppressor than as an oncogene in chemically induced skin carcinogenesis, with its absence contributing to both tumorigenesis and inflammation.

TI Variants of the Adenosine A(2A) Receptor Gene Are Protective against Proliferative Diabetic Retinopathy in Patients with Type 1 Diabetes SO OPHTHALMIC RESEARCH LA English DT Article DE Diabetes; Diabetic retinopathy; Single nucleotide polymorphism; Adenosine receptor ID ENDOTHELIAL GROWTH-FACTOR; NON-HISPANIC WHITES; PITTSBURGH EPIDEMIOLOGY; ADVANCED GLYCATION; FACTOR EXPRESSION; COMPLICATIONS; ACTIVATION; CELLS; MELLITUS; RISK AB Aims: The adenosine A(2A) receptor (ADORA(2A)) may ameliorate deleterious physiologic effects associated with tissue injury in individuals with diabetes. We explored associations between variants of the ADORA(2A) gene and proliferative diabetic retinopathy (PDR) in a cohort of patients with type 1 diabetes (T1D). Methods: The participants were from the Pittsburgh Epidemiology of Diabetes Complications prospective study of childhood-onset T1D. Stereoscopic photographs of the retinal fundus taken at baseline, then biennially, for 10 years were used to define PDR according to the modified Airlie House system. Two tagging single nucleotide polymorphisms (tSNPs; rs2236624-C/T and rs4822489-G/T) in the ADORA(2A) gene were selected using the HapMap (haplotype map) reference database. Results: A significant association was observed between SNP rs2236624 and PDR in the recessive genetic model. Participants homozygous for the T allele displayed a decreased risk of developing prevalent PDR (odds ratio, OR = 0.36; p = 0.04) and incident PDR (hazard ratio = 0.156; p = 0.009), and for all cases of PDR combined (OR = 0.23; p = 0.001). The protective effect of T allele homozygosity remained after adjusting for covariates. Similarly, for SNP rs4822489, an association between PDR and T allele homozygosity was observed following covariate adjustment (OR = 0.55; 95% CI: 0.31-0.92; p = 0.04). Conclusion: Genetic variants of ADORA(2A) offer statistically significant protection against PDR development in patients with T1D. Copyright (C) 2010 S.

Parotid glands are the likely target tissue for most clinical applications of salivary gene transfer. The purpose of the present study was to develop a convenient and reproducible method of retroductal gene transfer to mouse parotid glands. Methods: The volume for vector delivery was assessed by infusion of Toluidine Blue into Stensen's ducts of Balb/c mice after direct intraoral cannulation. Recombinant, serotype 5 adenoviral vectors, encoding either firefly luciferase or human erythropoietin (hEpo), were constructed and then administered to parotid glands (107 vector particles/gland). Transgene expression in vivo was measured by enzyme activity (luciferase) or an enzyme-linked immunosorbent assay (hEpo). Vector biodistribution was measured by real-time quantitative (Q) PCR. Results: The chosen volume for mouse parotid vector delivery was 20 mu L. Little vector was detected outside of the targeted glands, with both QPCR and luciferase assays. Transgene expression was readily detected in glands (luciferase, hEpo), and serum and saliva (hEpo). Most secreted hEpo was detected in saliva. Conclusion: These studies show that mouse parotid glands can be conveniently and reproducibly targeted for gene transfer, and should be useful for pre-clinical studies with many murine disease models.

TI Syntheses of mGluR5 PET radioligands through the radiofluorination of diaryliodonium tosylates SO ORGANIC & BIOMOLECULAR CHEMISTRY LA English DT Article ID POSITRON-EMISSION-TOMOGRAPHY; GLUTAMATE SUBTYPE-5 RECEPTORS; NEAR-UV PHOTOINITIATOR; PAIR ELECTRON-TRANSFER; SENSITIZED PHOTOLYSIS; DIPHENYLIODONIUM; SALTS; F-18; ION; CHEMISTRY AB 3-Fluoro-1-((thiazol-4-yl) ethynyl) benzenes constitute an important class of high-affinity metabotropic glutamate subtype 5 receptor (mGluR5) ligands, some of which have been labeled with fluorine-18 (t(1/2) = 109.7 min), to provide radioligands for molecular imaging of brain mGluR5 in living animal and human subjects with positron emission tomography (PET). Labeling in the 3-fluoro position of such ligands can be achieved through aromatic nucleophilic substitution of a halide leaving group with [(18)F] fluoride ion when a weakly activating m-nitrile group is present, but is generally very low yielding (< 8%). Here we used a microfluidic reaction platform to show that greatly enhanced (up to 6-fold) radiochemical yields can be achieved from suitably synthesized diaryliodonium tosylate precursors. The presence of a m-nitrile or other activating group is not required. Similar conditions were adopted in a more conventional automated radiochemistry platform having a single-pot reactor, to produce mGluR5 radioligands with useful radioactivities for PET imaging.

Our study suggests progressive hormonal changes that may contribute to severe bone loss during the year following hip fracture. Alterations in hormones affecting the musculoskeletal system may increase risk of hip fracture or poor post-fracture recovery in postmenopausal women. Most studies lack appropriate reference groups, and thus cannot assess the extent to which these alterations are attributable to hip fracture. Women aged a parts per thousand yen65 years hospitalized for an acute hip fracture (Baltimore Hip Studies, BHS-3; n = 162) were age-matched to 324 women enrolled in the Women's Health and Aging Study I, a Baltimore-based cohort with similar functional status to the pre-fracture status of BHS-3 women. Both studies enrolled participants from 1992 to 1995. Insulin-like growth hormone-1 (IGF-1), parathyroid hormone (PTH), 1,25 dihydroxyvitamin D [1,25(OH)2D], and osteocalcin were evaluated at baseline and 2, 6, and 12 months post-fracture, and at baseline and 12 months in the comparison group. Between-group differences in trajectories of each hormone were examined. Baseline mean IGF-1 levels were significantly lower in hip fracture patients than the comparison group (75.0 vs. 110.5 mu g/dL; p < 0.001). Levels increased by 2 months post-fracture, but remained significantly lower than those in the comparison group throughout the 12-month follow-up (p < 0.01). Levels of PTH and osteocalcin were similar between groups at baseline, but rose during the year post-fracture to significantly differ from the comparison women (p < 0.001). 1,25(OH)2D levels did not differ between the hip fracture and comparison women at any time. Older women who have sustained a hip fracture have progressive changes in hormonal milieu that exceed those of women of similar health status during the year following fracture. C1 [Cappola, A.

However, the exact role of each isoform in these processes remains unclear. This chapter reviews preclinical and clinical data on COX-1 and COX-2 inhibition in the neuroinflammatory and excitotoxic processes. Potential implications for clinical use in patients suffering from neurodegenerative disorders with a marked inflammatory component, such as Alzheimer's disease, are discussed.

The change in the rate of vaginal birth after caesarean section. Paediatric and Perinatal Epidemiology 2010. The objective of this study was to determine whether, and to what degree, the change in the vaginal birth after caesarean section (VBAC) rate is due to a change in the characteristics of the obstetric population, the undertaking of a trial of labour (TOL), or the tendency to abandon a TOL once it has been initiated. All women with one prior low transverse caesarean section (CS) and a vertex singleton gestation at term were identified in a registry of CS deliveries occurring at eight academic centres during a 4-year period (1999-2002). Women were classified by their predicted chance of VBAC and year-to-year differences were analysed. Of the 9643 women who met criteria for analysis, 5334 (55.3%) underwent a TOL. From 1999 to 2002, the VBAC rate underwent a steady decline: 51.8% to 45.1% to 37.4% to 29.8% (P < 0.001). Although there were some changes in the characteristics of the population that predispose to successful VBAC, as well as some reduction in the chance that a VBAC is successful once a TOL is undertaken, the most pervasive reason for this decline was that women became increasingly likely to forego a TOL, regardless of their likelihood of vaginal delivery. Based on these results, it appears that the change over time in the VBAC rate is multifactorial, although the greatest change has been a decrease in the frequency with which women undertake a TOL, and this change is observed in all categories of the chance of a successful TOL.

They enter neural cells though voltage-gated calcium channels and are activity-dependently transported along axons and across synapses. The aim of the present study was to investigate the nociceptive medial thalamus projection in rats by activity-dependent manganese-enhanced magnetic resonance imaging (MEMRI). Rats under urethane and a-chloralose anesthesia were microinjected with manganese chloride (MnCl(2), 120 mmol/L, iontophoretically with a 5-mu A current for 15 min) into the right medial thalamus. Innocuous (at a 50-mu A intensity for 0.2 ms) or noxious (at a 5-mA intensity for 2 ms) electrical stimuli were applied through a pair of needles in the left forepaw pads once every 6 s for 5 h. Enhanced transport of Mn(2+) were found in the anterior cingulate cortex, midcingulate cortex, retrosplenial cortex, ventral medial caudate-putamen, nucleus accumbens, and amygdala in the noxious-stimulated group. Enhancements in the anterior cingulate cortex, midcingulate cortex, ventral medial caudate-putamen, nucleus accumbens, and amygdala, but not the retrosplenial cortex, were attenuated by an intraperitoneal injection of morphine (5 mg/kg and 1 mg/kg/h, intraperitoneal). These results indicate that a combination of MEMRI with activity-induced manganese-dependent contrast is useful for delineating functional connections in the pain pathway.

We compared daily pain, home analgesic use, and utilization among ambulatory adults in the randomized Multicenter Study of Hydroxyurea in Sickle Cell Anemia (MSH). We related the fetal hemoglobin (HbF) hydroxyurea response to these response variables. Methods. Patients rated their sickle cell pain intensity (0-9), use of analgesics, and visits for pain daily. Diaries were collected biweekly, and intensity was collapsed into single interval ratings. The interval proportions of days of analgesic use and medical visits for pain were also calculated. Group comparisons were made by intention to treat as well as by HbF change levels from baseline to 2 years of treatment (placebo and low, medium, high, or very high response). Results. A total of 134 (44.8%) enrollees completed 2 years of follow-up. Pain intensity correlated with analgesic use (r = 0.83, P > 0.0001) and utilization (r = 0.50, P < 0.0001). Pain intensity was lower for patients on hydroxyurea (2.51 +/- 0.062 vs 2.82 +/- 0.063 placebo, F(1,270) = 11.65, P = 0.0007). The difference, though small, appeared early and was sustained. Analgesic use and utilization were also slightly lower (analgesic use: F(1,270) = 11.97, P = 0.0006; utilization: F(1,270) = 32.0, P < 0.0001). Each was statistically significantly lower among hydroxyurea patients with higher HbF treatment responses to hydroxyurea. Conclusions. Hydroxyurea usage led to a small, statistically significant reduction in daily pain, analgesic use, and utilization in adults in MSH, corroborating previously shown larger reductions in crises and mortality. The degree of daily symptomatic reduction was related to the size of the HbF treatment response, further confirming HbF response as a useful laboratory correlate.

There has been a growing recognition of the need for better pharmacologic management of chronic pain among older adults. To address this need, the National Institutes of Health Pain Consortium sponsored an "Expert Panel Discussion on the Pharmacological Management of Chronic Pain in Older Adults" conference in September 2010 to identify research gaps and strategies to address them. Specific emphasis was placed on ascertaining gaps regarding use of opioid and nonsteroidal anti-inflammatory medications because of continued uncertainties regarding their risks and benefits. Design. Eighteen panel members provided oral presentations; each was followed by a multidisciplinary panel discussion. Meeting transcripts and panelists' slide presentations were reviewed to identify the gaps and the types of studies and research methods panelists suggested could best address them. Results. Fifteen gaps were identified in the areas of treatment (e.g., uncertainty regarding the long-term safety and efficacy of commonly prescribed analgesics), epidemiology (e.g., lack of knowledge regarding the course of common pain syndromes), and implementation (e.g., limited understanding of optimal strategies to translate evidence-based pain treatments into practice). Analyses of data from electronic health care databases, observational cohort studies, and ongoing cohort studies (augmented with pain and other relevant outcomes measures) were felt to be practical methods for building an age-appropriate evidence base to improve the pharmacologic management of pain in later life. Conclusion. Addressing the gaps presented in the current report was judged by the panel to have substantial potential to improve the health and wellbeing of older adults with chronic pain.

To examine the prevalence and correlates of non-opioid and opioid analgesic use and descriptively evaluate potential undertreatment in a sample of community-dwelling elders with symptomatic knee and/or hip osteoarthritis (OA). Design. Cross-sectional. Setting. Health, Aging, and Body Composition Study. Patients. Six hundred and fifty-two participants attending the year 6 visit (2002-03) with symptomatic knee and/or hip OA. Outcome Measures. Analgesic use was defined as taking >= 1 non-opioid and/or >= 1 opioid receptor agonist. Non-opioid and opioid doses were standardized across all agents by dividing the daily dose used by the minimum effective analgesic daily dose. Inadequate pain control was defined as severe/extreme OA pain in the past 30 days from a modified Western Ontario and McMaster Universities Osteoarthritis Index. Results. Just over half (51.4%) reported taking at least one non-opioid analgesic and approximately 10% was taking an opioid, most (88.5%) of whom also took a non-opioid. One in five participants (19.3%) had inadequate pain control, 39% of whom were using <1 standardized daily dose of either a non-opioid or opioid analgesic. In adjusted analyses, severe/extreme OA pain was significantly associated with both non-opioid (adjusted odds ratio [AOR] = 2.44; 95% confidence interval [95% CI] = 1.49-3.99) and opioid (AOR = 2.64; 95% CI = 1.26-5.53) use. Conclusions. Although older adults with severe/extreme knee and/or hip OA pain are more likely to take analgesics than those with less severe pain, a sizable proportion takes less than therapeutic doses and thus may be undertreated. Further research is needed to examine barriers to optimal analgesic use. C1 [Marcum, Zachary A.] Univ Pittsburgh, Sch Med, Dept Med Geriatr, Pittsburgh, PA 15213 USA. [Kwoh, C.

The present study examined mean level similarities and differences as well as correlations between U. S. mothers' and fathers' attributions regarding successes and failures in caregiving situations and progressive versus authoritarian attitudes. Design. Interviews were conducted with mothers and fathers in 139 European American, Latin American, and African American families. Results. Interactions between parent gender and ethnicity emerged for adult-controlled failure and perceived control over failure. Fathers reported higher adult-controlled failure and child-controlled failure attributions than did mothers, whereas mothers reported attitudes that were more progressive and modern than did fathers; these differences remained significant after controlling for parents' age, education, and possible social desirability bias. Ethnic differences emerged for 5 of the 7 attributions and attitudes examined; 4 remained significant after controlling for parents' age, education, and possible social desirability bias. Medium effect sizes were found for concordance between parents in the same family for attributions regarding uncontrollable success, child-controlled failure, progressive attitudes, authoritarian attitudes, and modernity of attitudes after controlling for parents' age, education, and possible social desirability bias. Conclusions. This work elucidates ways that parent gender and ethnicity relate to attributions regarding U. S. parents' successes and failures in caregiving situations and to their progressive versus authoritarian parenting attitudes.

This article used the Parenting Across Cultures Project to evaluate similarities and differences in mean levels and relative agreement between mothers' and fathers' attributions and attitudes in parenting in 9 countries. Design. Mothers and fathers reported their perceptions of causes of successes and failures in caregiving and their progressive versus authoritarian childrearing attitudes. Gender and cultural similarities and differences in parents' attributions and attitudes in 9 countries were analyzed: China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Results. Although mothers and fathers did not differ in any attribution, mothers reported more progressive parenting attitudes and modernity of childrearing attitudes than did fathers, and fathers reported more authoritarian attitudes than did mothers. Country differences also emerged in all attributions and attitudes that were examined. Mothers' and fathers' attributions and their attitudes were moderately correlated, but parenting attitudes were more highly correlated in parents than were attributions. Conclusions. We draw connections among the findings across the 9 countries and outline implications for understanding similarities and differences in mothers' and fathers' parenting attributions and attitudes.

Zhang, Feng Shi, Jing-Shan Gao, Hui-Ming Hong, Jau-Shyong TI Transcriptional Factor NF-kappa B as a Target for Therapy in Parkinson's Disease SO PARKINSONS DISEASE LA English DT Review AB Parkinson's disease (PD) is a neurodegenerative condition characterized by chronic inflammation. Nuclear factor kappa B (NF-kappa B) is a family of inducible transcription factors that are expressed in a wide variety of cells and tissues, including microglia, astrocytes, and neurons, and the classical NF-kappa B pathway plays a key role in the activation and regulation of inflammatory mediator production during inflammation. Activation of the classical NF-kappa B pathway is mediated through the activity of the IKK kinase complex, which consists of a heterotrimer of IKK alpha, IKK beta, and IKK gamma subunits. Targeting NF-kappa B has been proposed as an approach to the treatment of acute and chronic inflammatory conditions, and the use of inhibitors specific for either IKK beta or IKK gamma has now been found to inhibit neurodegeneration of TH+ DA-producing neurons in murine and primate models of Parkinson's disease. These studies suggest that targeting the classical pathway of NF-kappa B through the inhibition of the IKK complex can serve as a useful therapeutic approach to the treatment of PD.

The advent of newer technologies and the realization that breast cancer is heterogeneous has shifted the focus to prognostication, with increased attention being paid to the identification of morphological features and immunohistochemical markers of prognostic relevance. However, despite the massive efforts invested in the identification of immunohistochemical biomarkers in breast cancer the majority have not proven to be of value in multivariate analyses and only estrogen receptor, progesterone receptor, and Her2/neu expression have remained essential components of pathological examination. These 3 markers were initially employed for prognostication but their role in treatment also rendered them of predictive value. Newer molecular methods, especially high-throughput technologies, have shown that even morphologically similar subtypes of breast cancer can show molecular heterogeneity; moreover, infiltrating ductal carcinoma can be separated into at least 4 molecular subtypes designated luminal (ER+, PR+, and Her2/neu-), Her2 overexpressing (ER-, PR-, and Her2/neu+), basal-like (ER-, PR-, Her2/neu-, and CK5/6+, EGFR+), and normal breast-like (ER-, PR-, and Her2/neu-), each with different clinical outcomes. The importance of proliferative gene expression in these subtypes has been demonstrated and surrogate immunohistochemical markers include ER, PR, Her2/neu, and Ki67 for the more expensive molecular tests. Molecular technologies, importantly, have not only provided further insights into the heterogeneity of breast cancer but have also opened new avenues for treatment through the identification of signaling molecules important in the proliferation and survival of the neoplastic cells. The treatment of cancer thus shifts from the conventional approach of 'one size fits all' to one of personalized treatment tailored to the specific characteristics of the tumor. Pathologists continue to play their traditional role in diagnosis but, as purveyors of the excised tissue, pathologists now have the additional role of identifying biomarkers responsive to therapeutic manipulation, thus playing an inextricable role as diagnostic oncologists in the management of breast cancer.

Circulating levels of glucocorticoids fluctuate naturally in a circadian fashion under the strong influence of the hypothalamic suprachiasmatic nucleus (SCN) circadian CLOCK system, and regulate the transcriptional activity of the GR in the brain and peripheral target tissues. We recently reported that the basic helix-loop-helix transcription factor Clock, which is a histone acetyltransferase and a central component of the self-oscillating transcription factor loop that generates circadian rhythms, represses GR transcriptional activity by acetylating lysine residues within the lysine cluster' located in the hinge region of the receptor. This Clock-mediated repression of GR transcriptional activity oscillates in inverse phase to the HPA axis, acting as a target tissue counter-regulatory mechanism to the diurnally fluctuating circulating glucocorticoids. Interestingly, mild evening elevations of cortisol, as occurs in chronic stress situations, and frequent uncoupling of the SCN CLOCK-directed HPA axis from the daily oscillation of target tissue sensitivity to glucocorticoids, as happens in trans-time zone travel and night shift work, produce functional hypercortisolism and, hence, multiple components of the metabolic syndrome with resultant cardiovascular complications.

Glucocorticoids slow longitudinal bone growth by inhibiting chondrocyte proliferation, hypertrophy, and cartilage matrix synthesis. The molecular mediators of these effects are poorly understood. Glucocorticoids also delay growth plate senescence. The decreased rate of senescence appears to be a consequence of the growth inhibition and, in particular, may occur because glucocorticoids slow proliferation of stem-like cells in the resting zone and therefore conserve the limited proliferative capacity of these cells. This slowing of senescence appears to explain the phenomenon of catch-up growth following transient glucocorticoid exposure. After the exposure, the growth plate is less senescent, and therefore grows more rapidly than is normal for age. Glucocorticoids cause growth inhibition and subsequent catch-up growth not only in terms of longitudinal bone growth at the growth plate but also in terms of cross-sectional bone growth at the periosteum. Whether the underlying mechanisms are analogous to those at the growth plate is not known. Copyright (C) 2011 S.

CA National Rotavirus Strain Surveill TI United States Rotavirus Strain Surveillance From 2005 to 2008 Genotype Prevalence Before and After Vaccine Introduction SO PEDIATRIC INFECTIOUS DISEASE JOURNAL LA English DT Article DE RotaTeq; rotavirus; strain; surveillance; US ID POLYMERASE CHAIN-REACTION; VP4 GENE; POPULATION; GASTROENTERITIS; IDENTIFICATION; DIVERSITY; CHILDREN; PREVENTION; REDUCTION; ROTARIX AB Background: A live, attenuated rotavirus vaccine, RotaTeq (R), was approved in 2006 for immunization of infants in the United States. To monitor the distribution of rotavirus genotypes before and after vaccine introduction, the Centers for Disease Control and Prevention conducted strain surveillance with the National Rotavirus Strain Surveillance System. Methods: Over 3 rotavirus seasons, 2005-2006, 2006-2007, and 2007-2008, National Rotavirus Strain Surveillance System laboratories collected rotavirus-positive stool specimens and submitted them to the Centers for Disease Control and Prevention. Rotavirus strains were G- and P-genotyped by multiplex reverse transcription-polymerase chain reaction or nucleotide sequencing. Results: During 2005-2006 and 2006-2007 seasons, G I was the dominant G-type but in the 2007-2008 season, G3 replaced GI as the most frequently detected strain. Four genotypes, G1P[8], G2P[4], G3P[8], and G9P[8] were detected in every season. Uncommon strains observed during the study period were G2P[8], G1P[6], G2P[6], G4P[6], G1P[4], G3P[9], G12P [6], and G12P[8]. The mean age of rotavirus cases in the 2007-2008 season increased significantly in patients less than 3 years old compared with the 2 previous seasons. Conclusions: The increased overall prevalence of G3P [8] strains in 2007-2008, the first rotavirus season with reasonable rotavirus vaccine coverage, was consistent with Australian reports of G3 dominance following RotaTeq introduction. However, these strain changes in both countries have occurred in the context of large declines in severe rotavirus disease and we cannot rule out that they are simply the result of naturally occurring changes in rotavirus strain prevalence. These findings underscore the need for careful monitoring of strains to assess possible vaccine pressure-induced changes and vaccine effectiveness against various rotavirus genotypes.

PATIENTS AND METHODS: We conducted a multicenter, retrospective analysis of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Perinatal and neonatal variables and outcomes were compared between epochs. Neurodevelopmental outcomes at 18 to 22 months' corrected age were evaluated with neurologic exams and Bayley Scales of Infant Development II. Logistic regression analyses determined the independent risk of epoch for adverse outcomes. RESULTS: Infant survival was similar between epochs (epoch 1, 35.4%, vs epoch 2, 32.3%; P = .09). A total of 411 of 452 surviving infants in epoch 1 and 405 of 438 surviving infants in epoch 2 were evaluated at 18 to 22 months' corrected age. Cesarean delivery (P = .03), surgery for patent ductus arteriosus (P = .004), and late sepsis (P = .01) were more common in epoch 2, but postnatal steroid use was dramatically reduced (63.5% vs 32.8%; P < .0001). Adverse outcomes at 18 to 22 months' corrected age were common in both epochs. Moderate-to-severe cerebral palsy was diagnosed in 11.1% of surviving infants in epoch 1 and 14.9% in epoch 2 (adjusted odds ratio [OR]: 1.52 [95% confidence interval (CI): 0.86-2.71]; P = .15), the Mental Developmental Index was <70 in 44.9% in epoch 1 and 51% in epoch 2 (OR: 1.30 [95% CI: 0.91-1.87]; P = .15), and neurodevelopmental impairment was diagnosed in 50.1% of surviving infants in epoch 1 and 58.7% in epoch 2 (OR: 1.4 [95% CI: 0.98-2.04]; P = .07). CONCLUSIONS: Early-childhood outcomes for infants born at <25 weeks' estimated gestational age were unchanged between the 2 periods.

TI Intercenter Differences in Bronchopulmonary Dysplasia or Death Among Very Low Birth Weight Infants SO PEDIATRICS LA English DT Article DE logistic models; infant; premature; predictive value of tests; clustering ID NEONATAL INTENSIVE-CARE; QUALITY IMPROVEMENT; PRETERM INFANTS; OUTCOMES; RATES AB OBJECTIVES: To determine (1) the magnitude of clustering of bronchopulmonary dysplasia (36 weeks) or death (the outcome) across centers of the Eunice Kennedy Shriver National Institute of Child and Human Development National Research Network, (2) the infant-level variables associated with the outcome and estimate their clustering, and (3) the center-specific practices associated with the differences and build predictive models. METHODS: Data on neonates with a birth weight of <1250 g from the cluster-randomized benchmarking trial were used to determine the magnitude of clustering of the outcome according to alternating logistic regression by using pairwise odds ratio and predictive modeling. Clinical variables associated with the outcome were identified by using multivariate analysis. The magnitude of clustering was then evaluated after correction for infant-level variables. Predictive models were developed by using center-specific and infant-level variables for data from 2001 2004 and projected to 2006. RESULTS: In 2001-2004, clustering of bronchopulmonary dysplasia/death was significant (pairwise odds ratio: 1.3; P < .001) and increased in 2006 (pairwise odds ratio: 1.6; overall incidence: 52%; range across centers: 32%-74%); center rates were relatively stable over time. Variables that varied according to center and were associated with increased risk of outcome included lower body temperature at NICU admission, use of prophylactic indomethacin, specific drug therapy on day 1, and lack of endotracheal intubation. Center differences remained significant even after correction for clustered variables. CONCLUSION: Bronchopulmonary dysplasia/death rates demonstrated moderate clustering according to center. Clinical variables associated with the outcome were also clustered. Center differences after correction of clustered variables indicate presence of as-yet unmeasured center variables.

Methods: 56 stable PD patients were evaluated in a cross-sectional survey. Plasma samples were collected for Vit C (analyzed by HPLC with electrochemical detection) and high-sensitivity C-reactive protein (hs-CRP) determinations. Clinical records were reviewed for Hb, transferrin saturation (TSAT), ferritin, erythropoietin (EPO) dose, and other clinical parameters. Dietary Vit C intake was evaluated by patient survey and from patient records. Total Vit C removed during PD treatment was measured in 24-hour dialysate collections. Results: Patients showed a highly skewed distribution of plasma Vit C levels, with 40% of patients below normal plasma Vit C levels (<30 mu mol/L) and 9% at higher than normal levels (>80 mu mol/L). Higher plasma Vit C levels were associated with higher Hb levels (Pearson r = 0.33, p < 0.004). No direct connection between Vit C levels and reported dietary intake could be established. In stepwise multiple regression, plasma Vit C remained significantly associated with Hb (p = 0.017) but there was no significant association with other variables (dialysis vintage, age, ferritin, TSAT, hs-CRP, residual renal function, and EPO dose). In 9 patients that were evaluated for Vit C in dialysate, plasma Vit C was positively associated (Spearman r = 0.85, p = 0.01) with the amount of Vit C removed during dialysis treatment. Conclusions: These data indicate that plasma Vit C is positively associated with higher Hb level. Vit C status could play a major role in helping PD patients to utilize iron for erythropoiesis and achieve a better Hb response during anemia management.

In the first experiment, individuals whose self-control capacity was depleted were more likely to misrepresent how many problems they solved and work after being told to stop while working on a timed test. These same results were found in individuals low in trait self-control. This was especially true when the certainty of getting caught was low. In the second experiment, depleted individuals were ruder to the experimenter than nondepleted participants. The results have implications for understanding how self-control contributes to normative behavior. C1 [DeBono, Amber; Muraven, Mark] SUNY Albany, Albany, NY 12065 USA.

One reason for this development is that the properties of nanomaterials (optical, scattering, physical) can be dramatically different than those of macro-based technologies. Many of these unique properties can be exploited to develop novel imaging agents and delivery systems. A host of biologically relevant molecules can be conjugated to nanoparticles to functionalize these platforms. Cellular glycans are one family of biomolecules that have been coated on different nanoparticle platforms and some of these tools are being successfully employed for specific biomedical applications. To date however, the application of these so-called glyconanoparticles for antitumor therapeutics has been sparse. Fortunately, some initial results with glyconanoparticles have been very encouraging for possible translation to clinically relevant anti-tumor therapies. This chapter will examine the most recent work reported on the synthesis, development and application of the most promising platforms.

The formation of thyroid hormones requires the accumulation of I(-) by the electrogenic Na(+)/I(-) symporter, which depends on the electrochemical gradient across the cell membrane and thus on K(+) channel activity. The present paper explored whether Kcnq1, a widely expressed voltage-gated K(+) channel, participates in the regulation of thyroid function. To this end, Kcnq1 expression was determined by RT-PCR, confocal microscopy, and thyroid function analyzed in Kcnq1 deficient mice (Kcnq1(-/-)) and their wild-type littermates (Kcnq1(+/+)). Moreover, Kcnq1 abundance and current were determined in the thyroid FRTL-5 cell line. Furthermore, mRNA encoding KCNQ1 and the subunits KCNE1-5 were discovered in human thyroid tissue. According to patch-clamp TSH (10 mUnits/ml) induced a voltage-gated K(+) current in FRTL-5 cells, which was inhibited by the Kcnq inhibitor chromanol (10 mu M). Despite a tendency of TSH plasma concentrations to be higher in Kcnq1(-/-) than in Kcnq1(+/+) mice, the T3 and T4 plasma concentrations were significantly smaller in Kcnq1(-/-) than in Kcnq1(+/+) mice. Moreover, body temperature was significantly lower in Kcnq1(-/-) than in Kcnq1(+/+) mice. In conclusion, Kcnq1 is required for proper function of thyroid glands.

The matricellular protein thrombospondin-1 (TSP1), through interaction with its receptor CD47, inhibits soluble guanylyl cyclase (sGC) activation by NO in vascular cells. In vascular smooth muscle cells (VSMCs) both intracellular cGMP and cAMP regulate adhesion, contractility, proliferation, and migration. cGMP can regulate cAMP through feedback control of hydrolysis. Inhibition of the cAMP phosphodiesterase-4 selectively interfered with the ability of exogenous TSP1 to block NO-driven VSMC adhesion but not cGMP accumulation, suggesting that cAMP also contributes to VSMC regulation by TSP1. Inhibition of phosphodiesterase-4 was sufficient to elevate cAMP levels, and inhibiting guanylyl cyclase or phosphodiesterase-3, or adding exogenous TSP1 reversed this increase in cAMP. Thus, TSP1 regulates VSMC cAMP levels in part via cGMP-dependent inhibition of phosphodiesterase-3. Additionally basal cAMP levels were consistently elevated in both VSMCs and skeletal muscle from TSP1 null mice, and treating null cells with exogenous TSP1 suppressed cAMP levels to those of wild type cells. TSP1 inhibited both forskolin and isoproterenol stimulated increases in cAMP in VSMCs. TSP1 also abrogated forskolin and isoproterenol stimulated vasodilation. Consistent with its ability to directly limit adenylyl cyclase-activated vasodilation, TSP1 also limited cAMP-induced dephosphorylation of myosin light chain-2. These findings demonstrate that TSP1 limits both cGMP and cAMP signaling pathways and functional responses in VSMCs and arteries, by both phosphodiesterase-dependent cross talk between these second messengers and by inhibition of adenylyl cyclase activation.

However, little is known about the binding energies in non-covalent complexes containing these functional groups. Here, we present a first study focused on quantifying such interactions using complexes of phosphorylated A(3)pXA(3)-NH2 (X = S, T, Y) peptides with decamethonium (DCM) or diaguanidinodecane (DGD) ligands as model systems. Time-and collision energy-resolved surface-induced dissociation (SID) of the singly charged complexes was examined using a specially configured Fourier transform ion cyclotron resonance mass spectrometer (FTICR-MS). Dissociation thresholds and activation energies were obtained from RRKM modeling of the experimental data that has been described and carefully characterized in our previous studies. For systems examined in this study, covalent bond cleavages resulting in phosphate abstraction by the cationic ligand are characterized by low dissociation thresholds and relatively tight transition states. In contrast, high dissociation barriers and large positive activation entropies were obtained for cleavages of non-covalent bonds. Dissociation parameters obtained from the modeling of the experimental data are in excellent agreement with the results of density functional theory (DFT) calculations. Comparison between the experimental data and theoretical calculations indicate that phosphate abstraction by the ligand is rather localized and mainly affected by the identity of the phosphorylated side chain. The hydrogen bonding in the peptide and ligand properties play a minor role in determining the energetics and dynamics of the phosphate abstraction channel.

To match the needs of research and the clinic, detection limits and specificities need to improve, however. One mechanism is to decrease non-specific background signals, which is most efficiently done by increasing fluorescence quenching abilities. Reports in the literature of theoretical and experimental work have shown that metallic gold surfaces and nanoparticles are ultra-efficient fluorescence quenchers. Based on these findings, subsequent reports have described gold nanoparticle fluorescence-based activatable probes that were designed to increase fluorescence intensity based on a range of stimuli. In this way, these probes can detect and signify assorted biomarkers and changes in environmental conditions. In this review, we explore the various factors and theoretical models that affect gold nanoparticle fluorescence quenching, explore current uses of activatable probes, and propose an engineering approach for future development of fluorescence based gold nanoparticle activatable probes.

This constrained Arg analog, denoted c(5)Arg, was engineered to also promote the stability of the CREKA bioactive conformation. The conformational profile of the CREKA analog obtained by replacing Arg by c(5)Arg has been extensively investigated in this work. Two molecular dynamics simulations-based strategies have been employed: a modified simulated annealing and replica exchange. Results obtained using both techniques show that the conformational features of the new analog fulfill the purpose of its design. The new CREKA analog not only preserves the main structural attributes found for the bioactive conformation of the parent peptide but also shows lower flexibility. Moreover, the conformational profile of the mutated peptide narrows towards the most stable structures previously observed for the parent CREKA peptide.

We use hybrid density functional calculations to study pT along quasi one-dimensional water arrays that connect an imidazolium-imidazole proton donor-acceptor pair. We characterize the structures of intermediates and transition states, the energetics, and the dynamics of the pT reactions, including vibrational contributions to kinetic isotope effects. In molecular dynamics simulations of pT transition paths, we find that for short water chains with four water molecules, the pT reactions are semi-concerted. The formation of a high-energy hydronium intermediate next to the proton-donating group is avoided by a simultaneous transfer of a proton from the donor to the first water molecule, and from the first water molecule into the water chain. Lowering the dielectric constant of the environment and increasing the water chain length both reduce the barrier for pT. We study the effect of the driving force on the energetics of the pT reaction by changing the proton affinity of the donor and acceptor groups through halogen and methyl substitutions. We find that the barrier of the pT reaction depends linearly on the proton affinity of the donor but is nearly independent of the proton affinity of the acceptor, corresponding to Bronsted slopes of one and zero, respectively.

In such nanoscale confinement, water has unusual physical properties that are exploited in biology and hold promise for a wide range of biomimetic and nanotechnological applications. The latter can be realized by carbon and boron nitride nanotubes which confine water in a relatively non-specific way and lend themselves to the study of intrinsic properties of single-file water. As a consequence of strong water-water hydrogen bonds, many characteristics of single-file water are conserved in biological and synthetic pores despite differences in their atomistic structures. Charge transport and orientational order in water chains depend sensitively on and are mainly determined by electrostatic effects. Thus, mimicking functions of biological pores with apolar pores and corresponding external fields gives insight into the structure-function relation of biological pores and allows the development of technical applications beyond the molecular devices found in living systems. In this Perspective, we revisit results for single-file water in apolar pores, and examine the similarities and the differences between these simple systems and water in more complex pores.

We explore here the application of a one-dimensional diffusion model to interpret simulations of protein folding, where the parameters of a model that "best" describes the simulation trajectories are determined using a Bayesian analysis. We discuss the requirements for such a model to be a good approximation to the global dynamics, and several methods for testing its accuracy. For example, one test considers the effect of an added bias potential on the fitted free energies and diffusion coefficients. Such a bias may also be used to extend our approach to determining parameters for the model to systems that would not normally explore the full coordinate range on accessible time scales. Alternatively, the propagators predicted from the model at different "lag" times may be compared with observations from simulation. We then present some applications of the model to protein folding, including Kramers-like turnover in folding rates of coarse-grained models, the effect of non-native interactions on folding, and the effect of the chosen coordinate on the observed position-dependence of the diffusion coefficients. Lastly, we consider how our results are useful for the interpretation of experiments, and how this type of Bayesian analysis may eventually be applied directly to analyse experimental data.

However, the emerging concept of 'functional amyloid' has taken a new direction into how we view amyloid. Recent studies have identified amyloid fibrils ranging from bacteria to humans that have a beneficial role, instead of being associated with a misfolded state that has been implicated in diseases such as Alzheimer's, Parkinson's and prion diseases. Here, we review our work on two human amyloidogenic polypeptides, one associated with Parkinson's disease, alpha-synuclein (alpha-syn), and the other important for melanin synthesis, the repeat domain (RPT) from Pmel17. Particularly, we focused our attention on spectroscopic studies of protein conformation and dynamics and their impact on alpha-syn amyloid formation and for RPT, we discussed the strict pH dependence of amyloid formation and its role in melanin biosynthesis.

The UEGMS is one of five BAMF ordinal scales designed for quick documentation of gross, fine, and oral motor skill levels. Designed to be independent of age and diagnosis, it is intended for use for infants through young adults. An expert panel of 17 physical therapists and 13 occupational therapists refined the content by responding to a standard questionnaire comprised of questions, which asked whether each item should be included, is clearly worded, should be reordered higher or lower, is functionally relevant, and is easily discriminated. Ratings of content validity exceeded the criterion except for two items, which may represent different perspectives of physical and occupational therapists. The UEGMS was modified using the quantitative and qualitative feedback from the questionnaires. For reliability, five raters scored videotaped motor performances of 10 children. Coefficients for inter-rater (0.94) and intra-rater (0.95) reliability were high. The results provide evidence of content validity and reliability of the UEGMS for the assessment of UEGM skill.

Giaja gained his PhD at the Sorbonne in 1909. In 1910 he established the first Chair of Physiology in the Balkans and organized the first Serbian Institute for Physiology at the School of Philosophy of the University of Belgrade. He led this Institute for more than 40 subsequent years. His most notable papers were in the field of thermoregulation and bioenergetics. Djaja became member of the Serbian and Croatian academies of science and doctor honoris causa of Sorbonne. In 1952 for the seminal work on the behavior of deep cooled warm blooded animals he became associate member of the National Medical Academy in Paris. In 1955 the French Academy of Sciences elected him as associate member in place of deceased Sir Alexander Fleming. Djaja died in 1957 during a congress held in his honor. He left more than 200 scientific and other papers and the golden DaVincian credo "Nulla dies sine experimento". His legacy was continued by several generations of researchers, the most prominent among them being Stefan Gelineo, Radoslav Andjus and Vojislav Petrovic. C1 [Andjus, P.

The condition consists of a mitochondrial myopathy associated with unique platelet pathology. Their mitochondrial myopathy has not been completely delineated and will be the subject of further study. Platelet pathology in the new patient is essentially identical to that described in the first two patients. Thin sections of her thrombocytes reveal a normal complement of alpha alpha and delta delta granules (dense bodies) in some, a decreased number in others and complete absence in a few. The unique pathological feature is the presence of giant organelles, including an intensely electron dense, huge body, the opaque organelle (OO) and a multilayered large body, the target organelle. In addition platelets from the new patient contain large masses and coils of smooth endoplasmic reticulum present infrequently in platelets of the first two patients. The giant opaque and target organelles appear to develop in rough and smooth endoplasmic reticulum of the parent megakaryocyte and mature in the dense tubular system of circulating platelets. The relationship of the unique platelet pathology and mitochondrial myopathy has not been defined.= 3 g/dL and/or >= 10% clonal bone marrow plasma cells, in the absence of end-organ damage. Based on clinical observations, the natural history of SMM varies greatly, from stable, monoclonal gammopathy of undetermined significance (MGUS)-like disease to highly progressive disease. Using conventional clinical markers, SMM patients can be stratified into clinical risk groups. However, due to considerable molecular heterogeneity, we currently lack reliable markers to predict prognosis for individual SMM patients. Based on the International Myeloma Working Group 2010 guidelines, patients diagnosed with MGUS and SMM should not be treated outside of clinical trials. Overall, treatment trials for MGUS patients are complicated, as these individuals are relatively healthy and the majority has a low life-time risk of progression, especially when other causes of death are taken into account. In contrast to MGUS, early treatment strategies for SMM are particularly attractive, as the rate of progression to multiple myeloma is substantially higher. Until recently, potent drugs with reasonable toxicity profiles have not been available for the development of early multiple myeloma treatment strategies. This review discusses how the integration of novel biological markers and clinical monitoring of SMM could facilitate the development of early treatment strategies for high-risk SMM patients in the future.

Imaging plays an important role in the clinical management of patients with prostate cancer. An important goal for prostate cancer imaging is more accurate disease characterization through the synthesis of anatomic, functional, and molecular imaging information. Positron emission tomography (PET)/computed tomography (CT) in oncology is emerging as an important imaging tool. The most common radiotracer for PET/CT in oncology, F-18-fluorodeoxyglucose (FDG), is not very useful in the imaging of prostate cancer. However, in recent years other PET tracers have improved the accuracy of PET/CT imaging of prostate cancer. Among these, choline labeled with F-18 or C-11, C-11-acetate, and F-18-fluoride has demonstrated promising results, and other new radiopharmaceuticals are under development and evaluation in preclinical and clinical studies. Large prospective clinical PET/CT trials are needed to establish the role of PET/CT in prostate cancer patients. Because there are only limited available therapeutic options for patients with advanced metastatic prostate cancer, there is an urgent need for the development of more effective treatment modalities that could improve outcome. Prostate cancer represents an attractive target for radioimmunotherapy (RIT) for several reasons, including pattern of metastatic spread (lymph nodes and bone marrow, sites with good access to circulating antibodies) and small volume disease (ideal for antigen access and antibody delivery). Furthermore, prostate cancer is also radiation sensitive. Prostate-specific membrane antigen is expressed by virtually all prostate cancers, and represents an attractive target for RIT. Antiprostate-specific membrane antigen RIT demonstrates antitumor activity and is well tolerated. Clinical trials are underway to further improve upon treatment efficacy and patient selection. This review focuses on the recent advances of clinical PET/CT imaging and RIT of prostate cancer. Semin Nucl Med 41:29-44 (C) 2011 Elsevier Inc. All rights reserved.

Dmrt1 and sox9a showed exclusive expression in male gonads while ovarian aromatase (cyp19a1) and foxl2 were abundant in differentiating female gonads. Most of the genes related to steroidogenesis were expressed only after gonadal differentiation. However, genes coding for 3 beta-hydroxysteroid dehydrogenase (3 beta-hsd), 17 alpha-hydroxylase/C17-20 lyase type 1 (cyp17) and steroidogenic acute regulatory protein (star) were barely detectable during gonadal differentiation. Ovarian aromatase, cyp19a1, which is responsible for estradiol-17 beta biosynthesis in females, was expressed very early in the undifferentiated gonads of catfish, around 30-40 days post hatch (dph). The steroidogenic enzyme, 11 beta-hydroxylase (cyp11b1) required for the production of 11-ketotestosterone (11-KT) was expressed only after differentiation of testis. These results suggest that estradiol-17 beta has a critical role in ovarian differentiation, while the role of 11-KT in testicular differentiation is doubtful. In conclusion, dimorphic expression of dmrt1 and sox9a in gonads during early development is required for testicular differentiation, and sex-specific expression of cyp19a1 and foxl2 in females plays a critical role in ovarian development. Our study reveals that the critical period of gonadal differentiation in catfish starts around 30-40 dph when sex-specific genes showed differential expression. Copyright (C) 2011 S.

Liver-related morbidity and mortality has emerged as a leading problem in HIV-infected patients. Since aging, HIV infection and HAART all affect the liver, understanding the impact of the combination of these factors on liver disease is crucial for optimisation of care in the aging HIV-infected population.

These properties make magnetic tweezers uniquely suited for the study of DNA topology and topoisomerases at the single-molecule level. Single-molecule approaches, which are complementary to ensemble biochemical and structural approaches, have provided remarkable insights into the mechanisms of topoisomerase activity and interactions with DNA. Here, we describe how to make single-molecule measurements of topoisomerase activity with a magnetic tweezers instrument. We provide detailed instructions for preparing and characterizing DNA substrates, flow cells, and supercoilable DNA tethers.

Although aggression-related functional changes in the ventromedial prefrontal cortex (vmPFC) and frontopolar cortex (FPC) have been reported in adults, the neural correlates of aggressive behavior in adolescents, particularly in the context of structural neurodevelopment, are obscure. We used functional and structural magnetic resonance imaging (MRI) to measure the blood oxygenation level-depended signal and cortical thickness. In a block-designed experiment, 14-17-year old adolescents imagined aggressive and non-aggressive interactions with a peer. We show reduced vmPFC activation associated with imagined aggressive behavior as well as enhanced aggression-related activation and cortical thinning in the FPC with increasing age. Changes in FPC activation were also associated with judgments of the severity of aggressive acts. Reduced vmPFC activation was associated with greater aggression indicating its normal function is to exert inhibitory control over aggressive impulses. Concurrent FPC activation likely reflects foresight of harmful consequences that result from aggressive acts. The correlation of age-dependent activation changes and cortical thinning demonstrates ongoing maturation of the FPC during adolescence towards a refinement of social and cognitive information processing that can potentially facilitate mature social behavior in aggressive contexts.

They form a large number of polymorphic structures, including heterogeneous ionic pores in membranes as well as different types of fibrillar and globular structures on surfaces and in solution. Understanding the origin of these structures and the factors that influence their occurrence is of great biomedical interest because of the possible relationship between structure and pathogenicity. Here, we use atomic force microscopy (AFM) and molecular dynamics (MD) simulations to demonstrate that at room temperature a truncated A beta peptide which is generated in vivo and shown to be toxic in vitro forms fibrillar structures on hydrophobic graphite surfaces, but not on hydrophilic mica or lipid bilayers. Our results suggest that the toxic pores and fibrillar polymorphic organizations can be explained in terms of the U-shaped beta-strand-turn-beta-strand structural motif observed for full length A beta and other amyloids, as well as the physicochemical properties at the interfaces. The interactions of the hydrophobic, truncated A beta with its environment illustrate that the universal amyloid motif can provide a link between the pore and fibrillar structures and indicate that surfaces with different physicochemical properties can shift the polymorphic landscape toward other conformational states.

TI Incorporation of the International Spinal Cord Injury Data Set elements into the National Institute of Neurological Disorders and Stroke Common Data Elements SO SPINAL CORD LA English DT Article DE spinal cord injury; International; Data Set; variable names; database specifications; common data element ID BASIC DATA SET AB Objectives: To develop consistent variable names and a common database structure for the data elements in the International Spinal Cord Injury (SCI) Data Sets. Setting: National Institute of Neurological Disorders and Stroke (NINDS) Common Data Elements (CDE) Project and The Executive Committee of the International SCI Standards and Data Sets committees (ECSCI). Methods: The NINDS CDE team creates a variable name for each defined data element in the various International SCI Data Sets. Members of the ECSCI review these in an iterative process to make the variable names logical and consistent across the data sets. Following this process, the working group for the particular data set reviews the variable names, and further revisions and adjustments may be made. In addition, a database structure for each data set is developed allowing data to be stored in a uniform way in databases to promote sharing data from different studies. Results: The International SCI Data Sets variable names and database specifications will be available through the web sites of the International Spinal Cord Society (http://www.iscos.org.uk), the American Spinal Injury Association (http://www.asia-spinalinjury.org) and the NINDS CDE project web site (http://www.CommonDataElements.ninds.nih.gov). Conclusion: This process will continue as additional International SCI Data Sets fulfill the requirements of the development and approval process and are ready for implementation.

The basis for this prohibition can be found in the World Anti-Doping Code, which defines the three criteria used to consider banning a substance. In this context, we discuss the potential of cannabis to enhance sports performance, the risk it poses to the athlete's health and its violation of the spirit of sport. Although these compounds are prohibited in-competition only, we explain why the pharmacokinetics of their main psychoactive compound, Delta(9)-tetrahydrocannabinol, may complicate the results management of adverse analytical findings. Passive inhalation does not appear to be a plausible explanation for a positive test. Although the prohibition of cannabinoids in sports is one of the most controversial issues in anti-doping, in this review we stress the reasons behind this prohibition, with strong emphasis on the evolving knowledge of cannabinoid pharmacology.

Researchers recognize that there is a need for high quality data. However, different annotation procedures, numerous databases, and a diminishing percentage of experimentally determined gene functions have resulted in a spectrum of annotation quality. NCBI in collaboration with sequencing centers, archival databases, and researchers, has developed the first international annotation standards, a fundamental step in ensuring that high quality complete prokaryotic genomes are available as gold standard references. Highlights include the development of annotation assessment tools, community acceptance of protein naming standards, comparison of annotation resources to provide consistent annotation, and improved tracking of the evidence used to generate a particular annotation. The development of a set of minimal standards, including the requirement for annotated complete prokaryotic genomes to contain a full set of ribosomal RNAs, transfer RNAs, and proteins encoding core conserved functions, is an historic milestone. The use of these standards in existing genomes and future submissions will increase the quality of databases, enabling researchers to make accurate biological discoveries.

Though in many cases experiments may be designed to minimize the occurrence of missing data, it is often unavoidable in practice; thus, statistical methods to account for missing data are needed. In this paper we describe an approach for conjoining multiple imputation and QTL mapping. Methods are applied to map genes associated with increased breathing effort in mice after lung inflammation due to allergen challenge in developing lines of the Collaborative Cross, a new mouse genetics resource. Missing data poses a particular challenge in this study because the desired phenotype summary to be mapped is a function of incompletely observed dose-response curves. Comparison of the multiple imputation approach to two naive approaches for handling missing data suggest that these simpler methods may yield poor results: ignoring missing data through a complete case analysis may lead to incorrect conclusions, while using a last observation carried forward procedure, which does not account for uncertainty in the imputed values, may lead to anti-conservative inference. The proposed approach is widely applicable to other studies with missing phenotype data. C1 [Bobb, Jennifer F.; Scharfstein, Daniel O.] Johns Hopkins Bloomberg Sch Publ Hlth, Baltimore, MD 21205 USA.

We propose a two-stage sequential design for these studies and investigate the cost of the sample size versus the statistical power. In a typical sequential design, a single normally distributed test statistic is used. For a genetic study, the robust test is used because of the uncertainty of the underlying genetic model (e. g. the recessive, additive or dominant models). The robust test statistic that we consider in the two-stage sequential design is the maximum of three correlated normally distributed statistics, each which is optimal under the corresponding genetic model. We study various factors that affect minimizing the average sample number (ASN) or maximizing the power of a gene-intervention study under the two-stage sequential design and make recommendations for the optimal solutions under different scenarios.

TI Comparing strategies to estimate the association of obesity with mortality via a Markov model SO STATISTICS AND ITS INTERFACE LA English DT Article DE Causation; Markov chain; Mortality; Obesity; Reverse causation ID BODY-MASS INDEX; DEATHS; UNDERWEIGHT; OVERWEIGHT; WEIGHT AB We used a first order discrete Markov model to investigate strategies to obtain unbiased estimates of the relative mortality hazard for comparing obese with non-obese participants. This hazard ratio is confounded by the fact that obese participants can be either sick or well, as can non-obese participants, and participants can migrate over time from their initial classification on obesity and health status. The parameters of the model were estimated from national survey data and used to illustrate different analytic approaches. The purpose was to compare analytic approaches and not to provide an analysis of a particular data set. Under this model, short term health-stratum-specific estimates are unbiased for estimating the health-stratum-specific instantaneous mortality hazard ratios from obesity, and updating information on body mass index and disease status during long term follow-up reduces bias. For follow-up over 10 or 20 years, exclusion of participants with preexisting disease, excluding the first five years of follow-up, and methods of analysis that ignore health status yield biased estimates of the instantaneous mortality hazard ratios. However, over 10 or 20 year time periods, long-term average mortality hazard ratios or cumulative mortality relative risks are a better reflection of the total impact of obesity, including its tendency to accelerate transitions to sickness under this model, than are instantaneous mortality hazard ratios. Over these longer time periods, average relative hazard estimates or cumulative mortality relative risks based on initially well participants, on initially sick participants, and on the combined initial population each provide valuable descriptions of associations of obesity with mortality.

We have previously shown that the adult stem cells originate from differentiated larval epithelial cells in the Xenopus laevis intestine. To clarify whether TH signaling in the epithelium alone is sufficient for inducing the stem cells, we have now performed tissue recombinant culture experiments using transgenic X. laevis tadpoles that express a dominant-positive TH receptor (dpTR) under a control of heat shock promoter. Wild-type (Wt) or dpTR transgenic (Tg) larval epithelium (Ep) was isolated from the tadpole intestine, recombined with homologous or heterologous nonepithelial tissues (non-Ep), and then cultivated in the absence of TH with daily heat shocks to induce transgenic dpTR expression. Adult epithelial progenitor cells expressing sonic hedgehog became detectable on day 5 in both the recombinant intestine of Tg Ep and Tg non-Ep (Tg/Tg) and that of Tg Ep and Wt non-Ep (Tg/Wt). However, in Tg/Wt intestine, they did not express other stem cell markers such as Musashi-1 and never generated the adult epithelium expressing a marker for absorptive epithelial cells. Our results indicate that, while it is unclear why some larval epithelial cells dedifferentiate into adult progenitor/stem cells, TR-mediated gene expression in the surrounding tissues other than the epithelium is required for them to develop into adult stem cells, suggesting the importance of TH-inducible epithelial-connective tissue interactions in establishment of the stem cell niche in the amphibian intestine.

In this study, we employed an ESC clonal line that contains a cardiac-restricted ncx1 promoter-driven puromycin resistance cassette together with a mass culture system to isolate ESC-CMs that display traits characteristic of very immature CMs. The cells display properties of proliferation, CM-restricted markers, reduced mitochondrial mass, and hypoxia-resistance. Following transplantation into rodent hearts, bioluminescence imaging revealed that immature cells, but not more mature CMs, survived for at least one month following injection. These data and comparisons with more mature cells lead us to conclude that immature hypoxia resistant ESC-CMs can be isolated in mass in vitro and, following injection into heart, form grafts that may mediate long-term recovery of global and regional myocardial contractile function following infarction.

However, each of the thousands of genes that comprise a genome must be phenotyped individually unless they can be assayed in parallel and subsequently deconvolved. To this end, unique molecular identifiers have been developed for a variety of microbes. Specifically, the addition of DNA "tags," or "bar codes," to each mutant allows all mutants in a collection to be pooled and phenotyped in parallel, greatly increasing experimental throughput. In this chapter, we provide an overview of current methodologies used to create such tagged mutant collections and outline how they can be applied to understand gene function, gene-gene interactions, and drug-gene interactions. Finally, we present a methodology that uses universal TagModules, capable of bar coding a wide range of microorganisms, and demonstrate its reduction to practice by creating tagged mutant collections in the pathogenic yeast Candida albicans.

Avp is increasingly recognised as an important modulator of the hypothalamic-pituitary-adrenal (HPA) axis, an action mediated by the Avpr1b present on anterior pituitary corticotrophs. The Avpr1b is also expressed in some peripheral tissues including pancreas and adrenal, and in the hippocampus (HIP), paraventricular nucleus and olfactory bulb of the rodent brain where its function is unknown. The central distribution of Avpr1bs is far more restricted than that of the Avpr1a, the main Avp receptor subtype found in the brain. Whether Avpr1b expression in rodent tissues is dependent on differences in the length of microsatellite dinucleotide repeats present in the 5' promoter region of the Avpr1b gene remains to be determined. One difficulty of functional studies on the Avpr1b, especially its involvement in the HPA axis response to stress, which prompted the generation of Avpr1b knockout (KO) mouse models, was the shortage of commercially available Avpr1b ligands, particularly antagonists. Research on mice lacking functional Avpr1bs has highlighted behavioural deficits in social memory and aggression. The Avpr1b KO also appears to be an excellent model to study the contribution of the Avpr1b in the HPA axis response to acute and perhaps some chronic (repeated) stressors where corticotrophin-releasing hormone and other genes involved in the HPA axis response to stress do not appear to compensate for the loss of the Avpr1b.

We present the safety data of that Trial ("Part 1") and the rationale for the design of Part 2. Methods-ALIAS Part 1 was designed to assess whether 25% albumin (ALB) started within 5 hours of stroke onset would confer neuroprotection in subjects with acute ischemic stroke and baseline National Institutes of Health Stroke Scale of >= 6. Exclusion criteria included recent or current congestive heart failure, myocardial infarction, or cardiac surgery. The study comprised 2 cohorts: subjects who received thrombolysis and those who did not, each with 1:1 randomization to ALB or placebo. The primary outcome was the National Institutes of Health Stroke Scale and modified Rankin Scales at 90 days. The intended sample size was 1800. Results-Four hundred thirty-four subjects were enrolled, and 424 were used in the safety analysis (ALB 207, saline 217). There were 36 deaths within the first 30 days in the ALB group and 21 in the saline group. In contrast, death rates after 30 days were similar by treatment. Large strokes were the predominant cause of early death in both groups. In subjects >83 years of age, 90-day death rates were 2.3-fold higher with ALB than with saline (95% CI, 1.04 to 5.12). Similarly, 90-day deaths in subjects receiving excessive fluids were 2.10-fold greater with ALB than with saline (CI, 1.10 to 3.98). Conclusions-The ALIAS Part 2 Trial, which started in early 2009, was modified as follows to enhance safety: upper age limit of 83 years; requirement for normal baseline serum troponin level; restriction of total intravenous fluids in the first 48 hours to <= 4200 mL; mandatory diuretic at 12 to 24 hours; and detailed site retraining. Because of insufficient nonthrombolysed subjects (22%) in Part 1, the 2-cohort design was eliminated. The Data Safety Monitoring Board has reviewed the safety data of Part 2 3 times and has approved continuation of the trial. (Stroke. 2011;42:119-127.)

More recent interest stems from a need to provide countermeasures against accidental or intentional exposure to radiation through nuclear devices. This chapter provides an overview of the biological effects of radiation and highlights models used to study radiation-induced damage and repair. In vitro and in vivo endpoints including DNA damage, cell survival, apoptosis, cytogenetic aberrations, oxidative stress, tumor response, and genomic instability are discussed. Appropriate use of these models will facilitate the advancement of radiation research as novel molecular mechanisms are elucidated.

The Canadian, US, and Australian guest editors contend that, when compared with other drugs used at a similar prevalence, VSM has attracted relatively little research effort. The authors and editors call for further research to develop evidence-based policies and comprehensive interventions that respect culture and context-specific knowledge.0.35 and >2.0 ng/mL/y have been associated with an increased risk of prostate cancer (CaP) death more than 10 years and 1 year before diagnosis, respectively. It is unknown how frequently PSAVs of this magnitude occur in community men. METHODS From the Baltimore Longitudinal Study of Aging, we examined the PSAV distribution in 786 men with serial PSA measurements (3474 PSAV observations) at total PSA levels <10 ng/mL. We also determined whether PSAV altered the probability of overall and life-threatening CaP at PSA levels <3 and 3-10 ng/mL. RESULTS Overall, the mean PSA and PSAV were 1.3 ng/mL and 0.05 ng/mL/y, respectively. PSAV rose continuously with increasing PSA (P < .0001), and was significantly higher in cancers than controls for observations at PSA levels <3 ng/mL (P = .02) and 3-10 ng/mL (P = .0008). The probability of life-threatening CaP was 3% at a PSA <3 ng/mL, but increased to 13.6% with PSAV >0.4 ng/mL/y. At PSA levels of 3-10 ng/mL, the probability of life-threatening CaP was 9.8% based on PSA alone vs 12% with PSAV >0.4 ng/mL/y. CONCLUSIONS PSAV was significantly higher in CaP observations than controls in all PSA ranges studied and altered the risk of overall and life-threatening CaP at a given PSA level. Because the value of PSAV is PSA-dependent, the PSA level should be taken into account when interpreting PSAV. UROLOGY 77: 143-148, 2011. (C) 2011 Published by Elsevier Inc.

Objective: To evaluate precision and recall of super-concepts for information retrieval in a multi-terminology paradigm compared to MeSH-only. Methods: We evaluate the relevance of resources retrieved by multi-terminology super-concepts and MeSH-only super-concepts queries. Results: Recall was 8-14% higher for multi-terminology super-concepts compared to MeSH only super-concepts. Precision decreased from 0.66 for MeSH only super-concepts to 0.61 for multi-terminology super-concepts. Retrieval performance was found to vary significantly depending on the super-concepts (p<10(-4)) and indexing methods (manual vs automatic; p<0.004). Conclusion: A multi-terminology paradigm contributes to increase recall but lowers precision. Automated tools for indexing are not accurate enough to allow a very precise information retrieval.

However, in some diseases, the severe pathological effects manifested by the causative agents are mediated entirely by protein toxins. Thus, it seems reasonable to expect that if antibodies could be induced against the protein toxin, they should be effective at preventing severe disease. Of course, the obvious challenge is to detoxify the protein toxin activity without destroying its ability to induce neutralizing antibodies. From an academic point of view, it is ironic that early vaccines against diphtheria, tetanus, and whooping cough were successful without understanding what made them work. One of the keys to this puzzle was uncovered quite by accident when it was discovered that diphtheria toxin stock preparations stored in large earthenware jars too large to be autoclaved were being detoxified by the residual formalin that leached into the preparations from the formalin-sterilized jars. It took two decades for this discovery to be understood and appreciated to a point at which formalin treatment could be applied to produce toxoid preparations for vaccination. It then took another half a century to develop the scientific tools and knowledge needed to bring forth the new generation of vaccines, which are highly effective and less reactogenic. This chapter traces the scientific history, controversies, and development of diphtheria, tetanus and pertussis vaccines. C1 Eunice Kennedy Shriver Natl Inst Child Hlth & Hum, NIH, Bethesda, MD USA.

TI Recommended Guidelines for the Conduct and Evaluation of Prognostic Studies in Veterinary Oncology SO VETERINARY PATHOLOGY LA English DT Article DE cancer; guidelines; prognostication; standardization; veterinary oncology ID MAST-CELL TUMORS; MULTIVARIATE DATA-ANALYSIS; MINIMUM INFORMATION; SURVIVAL ANALYSIS; APPENDICULAR OSTEOSARCOMA; PROTEIN EXPRESSION; CONSORT STATEMENT; DOGS; IMMUNOHISTOCHEMISTRY; QUALITY AB There is an increasing need for more accurate prognostic and predictive markers in veterinary oncology because of an increasing number of treatment options, the increased financial costs associated with treatment, and the emotional stress experienced by owners in association with the disease and its treatment. Numerous studies have evaluated potential prognostic and predictive markers for veterinary neoplastic diseases, but there are no established guidelines or standards for the conduct and reporting of prognostic studies in veterinary medicine. This lack of standardization has made the evaluation and comparison of studies difficult. Most important, translating these results to clinical applications is problematic. To address this issue, the American College of Veterinary Pathologists' Oncology Committee organized an initiative to establish guidelines for the conduct and reporting of prognostic studies in veterinary oncology. The goal of this initiative is to increase the quality and standardization of veterinary prognostic studies to facilitate independent evaluation, validation, comparison, and implementation of study results. This article represents a consensus statement on the conduct and reporting of prognostic studies in veterinary oncology from veterinary pathologists and oncologists from around the world. These guidelines should be considered a recommendation based on the current state of knowledge in the field, and they will need to be continually reevaluated and revised as the field of veterinary oncology continues to progress. As mentioned, these guidelines were developed through an initiative of the American College of Veterinary Pathologists' Oncology Committee, and they have been reviewed and endorsed by the World Small Animal Veterinary Association.

TI Proposal of a 2-Tier Histologic Grading System for Canine Cutaneous Mast Cell Tumors to More Accurately Predict Biological Behavior SO VETERINARY PATHOLOGY LA English DT Article DE canine; histologic grading; mast cell tumor ID MITOTIC INDEX; C-KIT; SURVIVAL; DOGS; PATHOLOGISTS; MORPHOMETRY; PROGNOSIS AB Currently, prognostic and therapeutic determinations for canine cutaneous mast cell tumors (MCTs) are primarily based on histologic grade. However, the use of different grading systems by veterinary pathologists and institutional modifications make the prognostic value of histologic grading highly questionable. To evaluate the consistency of microscopic grading among veterinary pathologists and the prognostic significance of the Patnaik grading system, 95 cutaneous MCTs from 95 dogs were graded in a blinded study by 28 veterinary pathologists from 16 institutions. Concordance among veterinary pathologists was 75% for the diagnosis of grade 3 MCTs and less than 64% for the diagnosis of grade 1 and 2 MCTs. To improve concordance among pathologists and to provide better prognostic significance, a 2-tier histologic grading system was devised. The diagnosis of high-grade MCTs is based on the presence of any one of the following criteria: at least 7 mitotic figures in 10 high-power fields (hpf); at least 3 multinucleated (3 or more nuclei) cells in 10 hpf; at least 3 bizarre nuclei in 10 hpf; karyomegaly (ie, nuclear diameters of at least 10% of neoplastic cells vary by at least two-fold). Fields with the highest mitotic activity or with the highest degree of anisokaryosis were selected to assess the different parameters. According to the novel grading system, high-grade MCTs were significantly associated with shorter time to metastasis or new tumor development, and with shorter survival time. The median survival time was less than 4 months for high-grade MCTs but more than 2 years for low-grade MCTs.

In this study, an infectious cDNA of OHFV was constructed to investigate the molecular mechanisms involved in OHFV pathogenesis for the first time. Our cDNA clone was capable of producing infectious virus which is genetically identical to the parental Guriev strain, and the recombinant virus showed similar biological properties to the parental virus including growth kinetics and virulence characteristics. While characterizing the cDNAs, fortuitous mutations at NS2A position 46 and NS5 position 836 were found to affect viral production. By using a viral replicon expressing luciferase, it was shown that both of the mutations produced a defect in RNA replication and that the NS5 mutation induced a temperature-sensitive phenotype, indicating the importance of these residues in RNA replication. This infectious cDNA will be a useful tool to study the replication and pathogenesis of OHFV. (C) 2010 Elsevier B.V. All rights reserved.

Four monitoring efforts were implemented which included tidal studies, hourly sampling, runoff sampling, and spatially intensive sediment sampling. Spatially intensive sediment sampling indicated that enterococci concentrations consistently decreased away from the inter-tidal zone, both seaward and landward. During dry conditions, the highest concentrations in the water were observed during high tide (71 +/- 48 CFU/100 mL) and lower concentrations were observed during low tide (4 +/- 3 CFU/100 mL). Runoff was characterised by very high levels (11,700 CFU/100 mL). Results from these monitoring efforts collectively showed that the source of enterococci to the study beach is geographically located within the inter-tidal zone. Wash-in from the inter-tidal zone through tidal action and runoff plays a major role in controlling enterococci levels within the water column. Such results are significant in identifying the source and transport mechanisms of enterococci, which can subsequently be used as part of a modelling effort aimed at predicting enterococci levels at recreational beaches.

This function is mammalian innovation and prestin orthologs in non-mammalian hair cells function as anion exchangers rather than a motile element. Taking advantage of this evolutionary change, we found that the sensitivity of prestin orthologs to membrane thickness is inversely related to their effectiveness for the motile function. In addition, a chimera between zebrafish prestin and rat prestin, which shows motile functionality, has membrane thickness sensitivity lower than any prestin ortholog we have examined, confirming the relationship.

Accumulating evidence suggests that representations within the lateral PFC enable people to orchestrate their thoughts and actions in concert with their intentions to support goal-directed social behavior. Despite the pivotal role of this region in guiding social interactions, remarkably little is known about the functional organization and forms of social knowledge mediated by the lateral PFC. Here, we review recent theoretical developments in evolutionary psychology and emerging evidence from the social and decision neuroscience literatures demonstrating the importance of the lateral PFC for orchestrating behavior on the basis of evolutionarily adaptive social norms for obligatory, prohibited, and permissible courses of action.

Accurate knowledge of the location and quantity of in vivo nanoconstructs and carriers is a challenging task, and newmethods of quantitative imaging at appropriate resolutions are being developed and tested. Sustaining simultaneous advancement in both imaging development and nanotechnology research requires multidisciplinary research teams conducting experiments with interconnected goals. On an even greater scale, networks of multidisciplinary teams focused on similar issues of imaging and probe development offer opportunities for leveraging resources, as well as providing a forum for sharing ideas and creating consensus on solutions to common challenges. The Network for Translational Research ( NTR): Optical Imaging in Multimodal Platforms from the National Cancer Institute is just such a network. Four multidisciplinary centers are accepting the challenges of developing and optimizing multimodal imaging hardware and software along with imaging probe development. These efforts are similar to the efforts that will be required for future studies of in vivo nanoparticle biodistribution. In addition to technology development and optimization, the network is organized to confront the challenges of validation of the imaging hardware and associated imaging agents, similar to the methods needed for validating nanomedicine.

Shoot cultures of sour cherry (Prunus cerasus L.) cultivars 'Dolgozdannaya', 'Moya Radost' and 'Zukovskaya', were cold stored at 4 degrees C in either five-section tissue-culture bags or in 150-ml glass jars. Carbon sources (3% sucrose, 2 or 3% mannitol, or 2% sucrose + 2% mannitol) were tested in Murashige and Skoog (MS) medium with or without plant growth regulators (PGRs). Nitrate nitrogen at 100, 50 or 25% of the normal MS concentration was also tested. In some treatments, shoot cultures of the three cherry cultivars stored at 4 degrees C remained viable for over 30 months. A significant variation in the storage duration and significant interactions of the cultivar, treatment, and container were observed. Sucrose was the best carbon source for all three genotypes and allowed storage for more than 30 months. Shoots stored on 2 or 3% mannitol survived only 6 to 12 months while the combination of 2% mannitol and 2% sucrose extended storage to 30 months. The addition of abscisic acid to 3% sucrose MS medium significantly decreased storage duration. 57 accessions of sour cherry germplasm were stored in tissue culture bags on 3% sucrose MS medium without PGRs and remained in good condition for 13 to 30 months. Currently, 68 P. cerasus germplasm accessions of the Kazakhstan National Cherry Collection are stored in tissue-culture bags with MS medium, PGRs, and 3% sucrose.

Disruption of tissue perfusion by ischemia or hemorrhage of blood vessels has a range of devastating consequences including stroke. Stroke is a complex trait that includes both genetic and environmental risk factors. The zebrafish is an attractive model for the study of hemorrhagic stroke due to the conservation of the molecular mechanisms of blood vascular development among vertebrates and the experimental advantages that can be applied to zebrafish embryos and larva. This chapter will focus on the maintenance of vascular integrity and some of the seminal experimentation carried out in the zebrafish.

The major complementary approaches and new uses of this technique include: Pseudotyped retroviruses have been used to deliver enhancer trap vectors, which allows selection of insertions in or near genes with particular expression patterns. Although the mutagenicity of these vectors has yet to be determined, they are useful purely because they generate a large number of transgenic lines with visible reporters (e.g., Green Fluorescent Protein GFP) expressed in interesting patterns and they provide information regarding gene regulation in the context of genomic organization. Gain-of-function vectors have been designed to allow for dominant genetic screens. Thus, genes whose overexpression results in phenotypes of interest can be efficiently identified. Retroviruses can be used to make a library of insertions in which hundreds of thousands of mapped insertions can be recovered from frozen sperm samples. Such libraries could serve as on-the-shelf reverse genetic resources, whereby one can obtain a mutation in nearly any gene by simply recovering an insertion in that gene from the frozen sperm, similar to the use of gene-trap insertions and genome-wide gene targeting in ES cells in the mouse. Transposons have been shown to be nearly as effective transgenesis vectors as retroviruses and thus may be used in similar screens - both for mutagenicity and gene traps and enhancer traps. It is possible that retroviruses and transposons could have different insertion site biases, making them important complementary technologies for genome-wide screening.

With the rapid development of the next-generation sequencing techniques, high throughput sequencing-based expression profiling techniques have been more and more widely adopted in molecular biology studies. In this chapter, we described a protocol for applying one of the sequencing-based expression profiling techniques, Digital Gene Expression (DGE), for zebrafish research. The protocol provides guidelines for wet-bench experimental procedures as well as for bioinformatics data analyses. We also discuss potential issues/challenges with the use of DGE.

Many cells, including DCs, are activated following stimulation of innate Toll-like receptors (TLRs) by products of microorganisms. In the resting (immature) state, MHC-II is ubiquitinated in immature DCs and is rapidly degraded; however, after activation of these cells with MyD88-dependent TLR ligands, MHC-II ubiquitination is blocked, and MHC-II survival is prolonged. We now show that DC activation using MyD88-dependent TLR ligands, MyD88-independent TLR ligands, and even infection with the intracellular parasite Toxoplasma gondii leads to identical changes in MHC-II expression, ubiquitination, and surface stability, revealing a conserved role for enhanced MHC-II stability after DC activation by different stimuli.

TI The RNA Transport Element of the Murine musD Retrotransposon Requires Long-range Intramolecular Interactions for Function SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; KISSING-LOOP INTERACTION; SELECTIVE 2'-HYDROXYL ACYLATION; SINGLE NUCLEOTIDE RESOLUTION; PRIMER EXTENSION SHAPE; REV RESPONSE ELEMENT; VIRAL MESSENGER-RNA; SECONDARY STRUCTURE; NUCLEAR EXPORT; MUTATIONAL ANALYSIS AB Retrovirus replication requires specialized transport mechanisms to export genomic mRNA from the nucleus to the cytoplasm of the infected cell. This regulation is mediated by a combination of viral and/or cellular factors that interact with cis-acting RNA export elements linking the viral RNA to the cellular CRM1 or NXF1 nuclear export pathways. Endogenous type D murine LTR retrotransposons (musD) were reported to contain an RNA export element located upstream of the 3'-LTR. Although functionally equivalent, the musD export element, termed the musD transport element, is distinct from the other retroviral RNA export elements, such as the constitutive transport element of simian/Mason-Pfizer monkey retroviruses and the RNA transport element found in rodent intracisternal A-particle LTR retrotransposons. We demonstrate here that the minimal RNA transport element (musD transport element) of musD comprises multiple secondary structure elements that presumably serve as recognition signals for the cellular export machinery. We identified two classes of tertiary interactions, namely kissing loops and a pseudoknot. This work constitutes the first example of an RNA transport element requiring such structural motifs to mediate nuclear export. C1 [Le Grice, Stuart F.

Since endothelium-derived nitric oxide (NO) suppresses constitutively the release and vascular effects of thromboxane A(2) (TXA(2)), NO-deficiency is often associated with activation of thromboxane receptors (TP). In the present study we hypothesized that in the absence of NO, overactivation of the TP-receptor mediated cerebrovascular signaling pathway contributes to the development of vasomotion and CBF oscillations. Methodology/Principal Findings: Effects of pharmacological modulation of TP-receptor activation and its downstream signaling pathway have been investigated on CBF oscillations (measured by laser-Doppler flowmetry in anesthetized rats) and vasomotion (measured by isometric tension recording in isolated rat middle cerebral arteries, MCAs) both under physiological conditions and after acute inhibition of NO synthesis. Administration of the TP-receptor agonist U-46619 (1 mu g/kg iv.) to control animals failed to induce any changes of the systemic or cerebral circulatory parameters. Inhibition of the NO synthesis by nitro-L-arginine methyl esther (L-NAME, 100 mg/kg iv.) resulted in increased mean arterial blood pressure and a decreased CBF accompanied by appearance of CBF-oscillations with a dominant frequency of 148+/-2 mHz. U-46619 significantly augmented the CBF-oscillations induced by L-NAME while inhibition of endogenous TXA(2) synthesis by ozagrel (10 mg/kg iv.) attenuated it. In isolated MCAs U-46619 in a concentration of 100 nM, which induced weak and stable contraction under physiological conditions, evoked sustained vasomotion in the absence of NO, which effect could be completely reversed by inhibition of Rho-kinase by 10 mu M Y-27632. Conclusion/Significance: These results suggest that hypersensitivity of the TP-receptor - Rho-kinase signaling pathway contributes to the development of low frequency cerebral vasomotion which may propagate to vasospasm in pathophysiological states associated with NO-deficiency.

Methods: All affected individuals underwent a detailed ophthalmologic examination. Blood samples were collected and genomic DNA was extracted. A genome-wide scan was completed with fluorescently-labeled microsatellite markers on genomic DNA from affected and unaffected family members. Logarithms of odds (LOD) scores were calculated under a fully penetrant autosomal recessive model of inheritance. Results: Ophthalmic examination suggested that affected individuals have bilateral cataracts. Linkage analysis localized the critical interval to chromosome 8p with LOD scores of 3.19, and 3.08 at theta=0, obtained with markers D8S549 and D8S550, respectively. Haplotype analyses refined the critical interval to 37.92 cM (16.28 Mb) region, flanked by markers, D8S277 proximally and D8S1734 distally. Conclusions: Here, we report a new locus for autosomal recessive congenital cataract mapped to chromosome 8p in a consanguineous Pakistani family. C1 [Sabir, Namerah; Riazuddin, S.

SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID NONOCCUPATIONAL POSTEXPOSURE PROPHYLAXIS; MALE CIRCUMCISION; LIMITED KNOWLEDGE; HOMOSEXUAL-MEN; INFECTION; TRANSMISSION; RISK; TENOFOVIR; MACAQUES; TRIAL AB Background: Antiretroviral chemoprophylaxis before exposure is a promising approach for the prevention of human immunodeficiency virus (HIV) acquisition. Methods: We randomly assigned 2499 HIV-seronegative men or transgender women who have sex with men to receive a combination of two oral antiretroviral drugs, emtricitabine and tenofovir disoproxil fumarate (FTC-TDF), or placebo once daily. All subjects received HIV testing, risk-reduction counseling, condoms, and management of sexually transmitted infections. Results: The study subjects were followed for 3324 person-years (median, 1.2 years; maximum, 2.8 years). Of these subjects, 10 were found to have been infected with HIV at enrollment, and 100 became infected during follow-up (36 in the FTC-TDF group and 64 in the placebo group), indicating a 44% reduction in the incidence of HIV (95% confidence interval, 15 to 63; P=0.005). In the FTC-TDF group, the study drug was detected in 22 of 43 of seronegative subjects (51%) and in 3 of 34 HIV-infected subjects (9%) (P<0.001). Nausea was reported more frequently during the first 4 weeks in the FTC-TDF group than in the placebo group (P<0.001). The two groups had similar rates of serious adverse events (P=0.57). Conclusions: Oral FTC-TDF provided protection against the acquisition of HIV infection among the subjects. Detectable blood levels strongly correlated with the prophylactic effect.

SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID HEMATOLOGICALLY IMPORTANT MUTATIONS; MARROW-TRANSPLANTATION; RESPIRATORY-BURST; INTERFERON-GAMMA; INVOLVEMENT; DEFICIENCY; GP91-PHOX; INFECTION; THERAPY; DOMAIN AB Background: Failure to generate phagocyte-derived superoxide and related reactive oxygen intermediates (ROIs) is the major defect in chronic granulomatous disease, causing recurrent infections and granulomatous complications. Chronic granulomatous disease is caused by missense, nonsense, frameshift, splice, or deletion mutations in the genes for p22(sup phox), p40(sup phox), p47(sup phox), p67(sup phox) (autosomal chronic granulomatous disease), or gp91(sup phox) (X-linked chronic granulomatous disease), which result in variable production of neutrophil-derived ROIs. We hypothesized that residual ROI production might be linked to survival in patients with chronic granulomatous disease. Methods: We assessed the risks of illness and death among 287 patients with chronic granulomatous disease from 244 kindreds. Residual ROI production was measured with the use of superoxide-dependent ferricytochrome c reduction and flow cytometry with dihydrorhodamine oxidation assays. Expression of NADPH oxidase component protein was detected by means of immunoblotting, and the affected genes were sequenced to identify causal mutations. Results: Survival of patients with chronic granulomatous disease was strongly associated with residual ROI production as a continuous variable, independently of the specific gene affected. Patients with mutations in p47(sup phox) and most missense mutations in gp91(sup phox) (with the exception of missense mutations in the nucleotide-binding and heme-binding domains) had more residual ROI production than patients with nonsense, frameshift, splice, or deletion mutations in gp91(sup phox). After adolescence, mortality curves diverged according to the extent of residual ROI production. Conclusions: Patients with chronic granulomatous disease and modest residual production of ROI have significantly less severe illness and a greater likelihood of long-term survival than patients with little residual ROI production. The production of residual ROI is predicted by the specific NADPH oxidase mutation, regardless of the specific gene affected, and it is a predictor of survival in patients with chronic granulomatous disease.

Recent mouse studies show that avidity for host cells can play an important role in polyclonal antibody escape, and further that electrostatic charge of the hemagglutinin glycoprotein can contribute to such avidity. Methodology/Principal Findings: We test the role of glycoprotein charge on sequence data from the three major subtypes of influenza A in humans, using a simple method of calculating net glycoprotein charge. Of all subtypes, H3N2 in humans shows a striking pattern of increasing positive charge since its introduction in 1968. Notably, this trend applies to both hemagglutinin and neuraminidase glycoproteins. In the late 1980s hemagglutinin charge reached a plateau, while neuraminidase charge started to decline. We identify key groups of amino acid sites involved in this charge trend. Conclusions/Significance: To our knowledge these are the first indications that, for human H3N2, net glycoprotein charge covaries strongly with antigenic drift on a global scale. Further work is needed to elucidate how such charge interacts with other immune escape mechanisms, such as glycosylation, and we discuss important questions arising for future study.

Marston TI Inactivation of the FLCN Tumor Suppressor Gene Induces TFE3 Transcriptional Activity by Increasing Its Nuclear Localization SO PLOS ONE LA English DT Article ID HOGG-DUBE-SYNDROME; RENAL-CELL CARCINOMA; MELANOMA PROTEIN-B; BHD GENE; THERAPEUTIC TARGET; MTOR ACTIVATION; BREAST-CANCER; AURISTATIN-E; MITF; MICROPHTHALMIA AB Background: Germline mutations in a tumor suppressor gene FLCN lead to development of fibrofolliculomas, lung cysts and renal cell carcinoma (RCC) in Birt-Hogg-Dube syndrome. TFE3 is a member of the MiTF/TFE transcription factor family and Xp11.2 translocations found in sporadic RCC involving TFE3 result in gene fusions and overexpression of chimeric fusion proteins that retain the C-terminal DNA binding domain of TFE3. We found that GPNMB expression, which is regulated by MiTF, was greatly elevated in renal cancer cells harboring either TFE3 translocations or FLCN inactivation. Since TFE3 is implicated in RCC, we hypothesized that elevated GPNMB expression was due to increased TFE3 activity resulting from the inactivation of FLCN. Methodology/Principal Findings: TFE3 knockdown reduced GPNMB expression in renal cancer cells harboring either TFE3 translocations or FLCN inactivation. Moreover, FLCN knockdown induced GPNMB expression in FLCN-restored renal cancer cells. Conversely, wildtype FLCN suppressed GPNMB expression in FLCN-null cells. FLCN inactivation was correlated with increased TFE3 transcriptional activity accompanied by its nuclear localization as revealed by elevated GPNMB mRNA and protein expression, and predominantly nuclear immunostaining of TFE3 in renal cancer cells, mouse embryo fibroblast cells, mouse kidneys and mouse and human renal tumors. Nuclear localization of TFE3 was associated with TFE3 post-translational modifications including decreased phosphorylation. Conclusions/Significance: Increased TFE3 activity is a downstream event induced by FLCN inactivation and is likely to be important for renal tumor development. This study provides an important novel mechanism for induction of TFE3 activity in addition to TFE3 overexpression resulting from Xp11.2 translocations, suggesting that TFE3 may be more broadly involved in tumorigenesis.

However, technical problems associated with factor abundance and suitable ChIP reagents are common obstacles to these studies in many biological systems. We have used two completely different, widely applicable methods to determine by ChIP the genome-wide binding sites of the master myogenic regulatory transcription factor HLH-1 (CeMyoD) in C. elegans embryos. The two approaches, ChIP-seq and ChIP-chip, yield strongly overlapping results revealing that HLH-1 preferentially binds to promoter regions of genes enriched for E-box sequences (CANNTG), known binding sites for this well-studied class of transcription factors. HLH-1 binding sites were enriched upstream of genes known to be expressed in muscle, consistent with its role as a direct transcriptional regulator. HLH-1 binding was also detected at numerous sites unassociated with muscle gene expression, as has been previously described for its mouse homolog MyoD. These binding sites may reflect several additional functions for HLH-1, including its interactions with one or more co-factors to activate (or repress) gene expression or a role in chromatin organization distinct from direct transcriptional regulation of target genes. Our results also provide a comparison of ChIP methodologies that can overcome limitations commonly encountered in these types of studies while highlighting the complications of assigning in vivo functions to identified target sites.

In correlative studies the impact of sorafenib on cyclin D1 and Ki67 was assessed. Methodology/Principal Findings: Thirty-six patients treatment-naive advanced melanoma patients received sorafenib 400 mg p.o. twice daily continuously. Tumor BRAF V600E mutational status was determined by routine DNA sequencing and mutation-specific PCR (MSPCR). Immunohistochemistry (IHC) staining for cyclin D1 and Ki67 was performed on available pre- and post treatment tumor samples. The main toxicities included diarrhea, alopecia, rash, mucositis, nausea, hand-foot syndrome, and intestinal perforation. One patient had a RECIST partial response (PR) lasting 175 days. Three patients experienced stable disease (SD) with a mean duration of 37 weeks. Routine BRAF V600E sequencing yielded 27 wild-type (wt) and 6 mutant tumors, whereas MSPCR identified 12 wt and 18 mutant tumors. No correlation was seen between BRAF V600E mutational status and clinical activity. No significant changes in expression of cyclin D1 or Ki67 with sorafenib treatment were demonstrable in the 15 patients with pre-and post-treatment tumor samples. Conclusions/Significance: Sorafenib monotherapy has limited activity in advanced melanoma patients. BRAF V600E mutational status of the tumor was not associated with clinical activity and no significant effect of sorafenib on cyclin D1 or Ki67 was seen, suggesting that sorafenib is not an effective BRAF inhibitor or that additional signaling pathways are equally important in the patients who benefit from sorafenib. registration: C1 [Ott, Patrick A.; Min, Christina; Safarzadeh-Amiri, Sara; Goldberg, Lauren; Buckley, Michael; Osman, Iman; Liebes, Leonard; Pavlick, Anna C.] NYU, Sch Med, Dept Med Oncol, New York, NY 10003 USA.

CG-SLS experiments at high ionic strengths and in the presence of 5 mM Mg(2+) show that, while FtsZ self-associates in a noncooperative fashion, sZipA acts as a monomer. CG-SLS data obtained from mixtures of FtsZ (A) and sZipA (B) in the presence of Mg(2+) are quantitatively described by an equilibrium model that takes into account significant scattering contributions from B, A(1), A(2), A(3), A(4), A(5), A(6), A(1)B, A(2)B, A(3)B, and A(4)B. However, in the absence of Mg(2+) (with EDTA), the data are best explained by an equilibrium model in which only B, A(1), A(2), A(3), A(1)B, and A(2)B contribute significantly to scattering. The best-fit molecular weights of monomeric A and B are in good agreement with values calculated from amino acid composition and with values obtained from sedimentation equilibrium. The latter technique also confirmed the interaction between sZipA and GDP-FtsZ. Moreover, the association model that best describes the CG-SLS data is in qualitative agreement with the sedimentation data. From these results, it follows that the binding of sZipA to GDP-FtsZ is of moderate affinity and does not significantly affect the interactions between FtsZ monomers. Under the working conditions used, only one sZipA binds to FtsZ oligomers with a length of six at most. The observed behavior would be compatible with FtsZ fibrils being anchored in vivo to the bacterial inner plasma membrane by substoichiometric binding of membrane-bound ZipA.

Like most protein kinases, GSK-3 beta is regulated via multiple pathways and sites. We performed all-atom molecular dynamics simulations on the unphosphorylated and phosphorylated unbound GSK-3 beta and the phosphorylated GSK-3 beta bound to a peptide substrate, its product, and a derived inhibitor. We found that GSK-3 beta autophosphorylation at residue Tyr(216) results in widening of the catalytic groove, thereby facilitating substrate access. In addition, we studied the interactions of the phosphorylated GSK-3 beta with a substrate and peptide inhibitor located at the active site and observed higher affinity of the inhibitor to the kinase. Furthermore, we detected a potential remote binding site which was previously identified in other kinases. In agreement with experiments we observed that binding of specific peptides at this remote site leads to stabilization of the activation loop located in the active site. We speculate that this stabilization could enhance the catalytic activity of the kinase. We point to this remote site as being structurally conserved and suggest that the allosteric phenomenon observed here may occur in the protein kinase superfamily.

In the mutant TP53 MCL cells which are intrinsically resistant to bortezomib, the combination of Nutlin-3/bortezomib synergistically induced cytotoxicity through the mitochondrial apoptotic pathway mediated by transcription-independent upregulation of NOXA, sequestration of MCL-1, activation of BAX, BAK, caspase-9 and -3. In the bortezomib sensitive wild-type TP53 MCL cells, the Nutlin-3/bortezomib combination caused G0/G1 cell cycle arrest followed by the increase in apoptosis induction.

Double-strand breaks are produced via a single-strand nick that is converted to a hairpin end on coding DNA and a blunt end on the neighboring recombination signal sequence. We demonstrate that the C-terminal regions of purified murine RAG1 (aa 1009-1040) and RAG2 (aa 388-520, including a plant homeodomain [PHD domain]) collaborate to inhibit the hairpinning stage of DNA cleavage. The C-terminal region of RAG2 stabilizes the RAG1/2 heterotetramer but destabilizes the RAG-DNA precleavage complex. This destabilization is reversed by binding of the PHD domain to a histone H3 peptide trimethylated on lysine 4 (H3K4me3). The addition of H3K4me3 likewise alleviates the RAG1/RAG2 C-terminus-mediated inhibition of hairpinning and the PHD-mediated inhibition of transposition activity. Thus a negative regulatory function of the noncore regions of RAG1/2 limits the RAG endonuclease activity in the absence of an activating methylated histone tail bound to the complex.

The xeroderma pigmentosum C (XPC) protein is essential for initiating global genome NER by recognizing the DNA lesion and recruiting downstream factors. Here we show that inhibition of the deacetylase and longevity factor SIRT1 impairs global genome NER through suppressing the transcription of XPC in a SIRT1 deacetylase-dependent manner. SIRT1 enhances XPC expression by reducing AKT-dependent nuclear localization of the transcription repressor of XPC. Finally, we show that SIRT1 levels are significantly reduced inhuman skin tumors from Caucasian patients, a population at highest risk. These findings suggest that SIRT1 acts as a tumor suppressor through its role in DNA repair.

TI Proteasome and p97 mediate mitophagy and degradation of mitofusins induced by Parkin SO JOURNAL OF CELL BIOLOGY LA English DT Article ID REGULATES MITOCHONDRIAL MORPHOLOGY; ENDOPLASMIC-RETICULUM; PROTEOLYTIC CLEAVAGE; PROTEIN-DEGRADATION; PINK1; DISEASE; FUSION; MUTATIONS; DROSOPHILA; FISSION AB Damage to mitochondria can lead to the depolarization of the inner mitochondrial membrane, thereby sensitizing impaired mitochondria for selective elimination by autophagy. However, fusion of uncoupled mitochondria with polarized mitochondria can compensate for damage, reverse membrane depolarization, and obviate mitophagy. Parkin, an E3 ubiquitin ligase that is mutated in monogenic forms of Parkinson's disease, was recently found to induce selective autophagy of damaged mitochondria. Here we show that ubiquitination of mitofusins Mfn1 and Mfn2, large GTPases that mediate mitochondrial fusion, is induced by Parkin upon membrane depolarization and leads to their degradation in a proteasome-and p97-dependent manner. p97, a AAA+ ATPase, accumulates on mitochondria upon uncoupling of Parkin-expressing cells, and both p97 and proteasome activity are required for Parkin-mediated mitophagy. After mitochondrial fission upon depolarization, Parkin prevents or delays refusion of mitochondria, likely by the elimination of mitofusins. Inhibition of Drp1-mediated mitochondrial fission, the proteasome, or p97 prevents Parkin-induced mitophagy.

At least three mAChR subtypes (M-2, M-3, andM(4)) are present in the spinal dorsal horn. However, it is not clear how each mAChR subtype contributes to the regulation of glutamatergic input to dorsal horn neurons. We recorded spontaneous excitatory postsynaptic currents (sEPSCs) from lamina II neurons in spinal cord slices from wild-type (WT) and mAChR subtype knock-out (KO) mice. The mAChR agonist oxotremorine-M increased the frequency of glutamatergic sEPSCs in 68.2% neurons from WT mice and decreased the sEPSC frequency in 21.2% neurons. Oxotremorine-M also increased the sEPSC frequency in similar to 50% neurons fromM(3)-single KO andM(1)/M-3 double-KO mice. In addition, the M-3 antagonist J104129 did not block the stimulatory effect of oxotremorine-M in the majority of neurons from WT mice. Strikingly, in M-5-single KO mice, oxotremorine-M increased sEPSCs in only 26.3% neurons, and J104129 abolished this effect. InM2/M-4 double-KO mice, but not M-2-or M-4-single KO mice, oxotremorine-M inhibited sEPSCs in significantly fewer neurons compared with WT mice, and blocking group II/III metabotropic glutamate receptors abolished this effect. The M-2/M-4 antagonist himbacine either attenuated the inhibitory effect of oxotremorine-M or potentiated the stimulatory effect of oxotremorine-M in WT mice. Our study demonstrates that activation of the M-2 and M-4 receptor subtypes inhibits synaptic glutamate release to dorsal horn neurons. M-5 is the predominant receptor subtype that potentiates glutamatergic synaptic transmission in the spinal cord.

TI Substrate Channeling in Mammalian Base Excision Repair Pathways: Passing the Baton SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID DNA-POLYMERASE-BETA; DEOXYRIBOSE PHOSPHATE LYASE; LIGASE-I; BOVINE TESTIS; IDENTIFICATION; MECHANISM; CELLS; RECONSTITUTION; BINDING; PROTEIN AB The current model for base excision repair (BER) involves two general sub-pathways termed single-nucleotide BER and long patch BER that are distinguished by their repair patch sizes and the enzymes/co-factors involved. Both sub-pathways involve a series of sequential steps from initiation to completion of repair. The BER sub-pathways are designed to sequester the various intermediates, passing them along from one step to the next without allowing these toxic molecules to trigger cell cycle arrest, necrotic cell death, or apoptosis. Although a variety of DNA-protein and protein-protein interactions are known for the BER intermediates and enzymes/co-factors, the molecular mechanisms accounting for step-to-step coordination are not well understood. In the present study we designed an in vitro assay to explore the question of whether there is a channeling or "hand-off" of the repair intermediates during BER in vitro. The results show that when BER enzymes are pre-bound to the initial single-nucleotide BER intermediate, the DNA is channeled from apurinic/apyrimidinic endonuclease 1 to DNA polymerase beta and then to DNA ligase. In the long patch BER subpathway, where the 5'-end of the incised strand is blocked, the intermediate after DNA polymerase beta gap filling is not channeled to the subsequent enzyme, flap endonuclease 1. Instead, flap endonuclease 1 must recognize and bind to the intermediate in competition with other molecules.

Such tissue-specific protein expression implies regulation by a tissue-specific factor. In this study, we investigated SelW expression during myogenic C2C12 cell differentiation using RTPCR, quantitative PCR, and Western blot analysis. Both the protein and mRNA levels of SelW were increased during C2C12 cell differentiation, particularly during the early stage. Sequence analysis of the SelW promoter revealed four putative E-boxes, E1, E2, E3, and E4, which are known binding sites for MyoD, a myogenic transcriptional factor. Luciferase reporter assay showed that E1 and E4 were crucial for MyoD-dependent promoter activity. Using EMSA analysis, we observed that MyoD bound directly to E1 but not to E4, even though E4 mutation reduced SelW promoter activity in the luciferase reporter assay. Binding of MyoD to E1 was further investigated by ChIP assay. These results suggest that the SelW gene was activated by the binding of MyoD to a specific E-box during early skeletal muscle differentiation.

TI The 1.5 angstrom Crystal Structure of Human Receptor for Advanced Glycation Endproducts (RAGE) Ectodomains Reveals Unique Features Determining Ligand Binding SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID END-PRODUCTS RAGE; CELL-SURFACE RECEPTOR; PATTERN-RECOGNITION; SCAVENGER RECEPTORS; ALZHEIMERS-DISEASE; NMR SYSTEM; PROTEINS; ACTIVATION; S100B; CRYSTALLOGRAPHY AB Interaction of the pattern recognition receptor, RAGE with key ligands such as advanced glycation end products (AGE), S100 proteins, amyloid beta, and HMGB1 has been linked to diabetic complications, inflammatory and neurodegenerative disorders, and cancer. To help answer the question of how a single receptor can recognize and respond to a diverse set of ligands we have investigated the structure and binding properties of the first two extracellular domains of human RAGE, which are implicated in various ligand binding and subsequent signaling events. The 1.5-angstrom crystal structure reveals an elongated molecule with a large basic patch and a large hydrophobic patch, both highly conserved. Isothermal titration calorimetry (ITC) and deletion experiments indicate S100B recognition by RAGE is an entropically driven process involving hydrophobic interaction that is dependent on Ca2+ and on residues in the C'D loop (residues 54-67) of domain 1. In contrast, competition experiments using gel shift assays suggest that RAGE interaction with AGE is driven by the recognition of negative charges on AGE-proteins. We also demonstrate that RAGE can bind to dsDNA and dsRNA. These findings reveal versatile structural features of RAGE that help explain its ability to recognize of multiple ligands.

TI Local Sequence Targeting in the AID/APOBEC Family Differentially Impacts Retroviral Restriction and Antibody Diversification SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; INDUCED CYTIDINE DEAMINASE; CLASS SWITCH RECOMBINATION; SOMATIC HYPERMUTATION; HUMAN APOBEC3G; HIV-1 INFECTION; DNA INTEGRATION; IN-VIVO; AID; CELLS AB Nucleic acid cytidine deaminases of the activation-induced deaminase (AID)/APOBEC family are critical players in active and innate immune responses, playing roles as target-directed, purposeful mutators. AID specifically deaminates the host immunoglobulin (Ig) locus to evolve antibody specificity, whereas its close relative, APOBEC3G (A3G), lethally mutates the genomes of retroviral pathogens such as HIV. Understanding the basis for the target-specific action of these enzymes is essential, as mistargeting poses significant risks, potentially promoting oncogenesis (AID) or fostering drug resistance (A3G). AID prefers to deaminate cytosine in WRC (W = A/T, R = A/G) motifs, whereas A3G favors deamination of CCC motifs. This specificity is largely dictated by a single, divergent protein loop in the enzyme family that recognizes the DNA sequence. Through grafting of this substrate-recognition loop, we have created enzyme variants of A3G and AID with altered local targeting to directly evaluate the role of sequence specificity on immune function. We find that grafted loops placed in the A3G scaffold all produced efficient restriction of HIV but that foreign loops in the AID scaffold compromised hypermutation and class switch recombination. Local targeting, therefore, appears alterable for innate defense against retroviruses by A3G but important for adaptive antibody maturation catalyzed by AID. Notably, AID targeting within the Ig locus is proportionally correlated to its in vitro ability to target WRC sequences rather than non-WRC sequences. Although other mechanisms may also contribute, our results suggest that local sequence targeting by AID/APOBEC3 enzymes represents an elegant example of co-evolution of enzyme specificity with its target DNA sequence.
