We present baseline data (follow up due w24–48) from MSM Neurocog ‐ prospective cohort study describing neurocognitive (NC) function in men who have sex with men (MSM) 18–50y.ObjectivesDescribe prevalence of positive screen for NC impairment (NCI) using Brief Neurocognitive Screen (BNCS); follow NC function over time.Data collectedDemographics, medical history, current/nadir CD4, current/peak viral load, antiretroviral (ART) use, recreational drug/tobacco/alcohol use. Subjects screen for depression (PHQ9), anxiety (GAD7), subjective memory problems (Everyday Memory Questionnaire [EMQ]). PHQ9, GAD7, EMQ, IHDS have fixed numerical cut‐offs. BNCS interpreted by calculating composite z score for each subject based on distance from mean in three component tests. Comparing to population norms may overcall NCI. We used participants to construct HIV+ normal ranges after exclusion of anxiety/depression, comparing individuals to this range. 235 screened (205 HIV+, 30 HIV−). In HIV+group 59 (28.8%) excluded as GAD7>10, PHQ9>15 or both (2 no data). 144 HIV+ analysed. 124 (86.1%) had normal z score (within 1 SD of mean). 20 (13.9%) had abnormal z: 7 (35%) asymptomatic, 13 (65%) symptomatic (analysed together). Not enough cognitive domains assessed by BNCS to formally diagnose HIV‐related NCI. BNCS abnormals less likely to be educated at university level/beyond (40% vs. 62.1%, p=0.02) or in skilled work (45% vs. 81.5%, p<0.0001). Current/ex‐recreational drug use similar (~80%); no significant association to score. All patients with abnormal z receiving ART; individual agents not associated with abnormality. IHDS correlated with abnormal BNCS (60% abnormal z had abnormal IHDS vs. 15.3% of normal, p<0.0001). No CD4 association with abnormal z (median nadir 244 in both, p=0.38). Of note, group median age was statistically different but actual difference small (normal 41y vs. abnormal 44y p<0.0001; HIV− 33y). BNCS outcome is age‐related but stratification of results would make abnormal numbers too low for interpretation. In any case, no NCI seen following referral. No‐one referred for formal psychometric testing after screening shown to have NCI. We show high anxiety, depression and current/previous recreational drug use in HIV+MSM 18–50y. Subjective concerns do not translate into confirmed NCI. Patient pathways should include screening for anxiety/depression and substance use, but in this young MSM group concerns regarding memory/functional impairment seem unfounded.

Purpose of the studyTo describe long‐term incidence trends and median age at diagnosis for the three AIDS‐defining cancers (ADC) in HIV‐1‐ infected (HIV1+) patients compared to general population. To study the risk of ADC in HIV1+patients with good immune status (CD4≥500/mm3 for at least 2 years).MethodsIncident ADC (Kaposi's sarcoma [KS], non‐Hodgkin's lymphomas [NHL] and cervix uteri cancer [CUC]) were retrieved in HIV1+adults followed in the French hospital database on HIV (FHDH) cohort between 1992 and 2009. Cancer incidence rates (IR) in general population were calculated using data from the French cancer registries (Francim network). IR among the HIV1+and the general population were standardized using the 5 years age and sex groups structure of the HIV1+population (1997–2009) and standardized incidence ratios (SIR) were estimated in HIV1+ patients vs. general population in 4 calendar periods (1992–1996, 1997–2000, 2001–2004, and 2005–2009). Median age at diagnosis was estimated after adjusting for the difference in age structure between HIV1+and general population.Summary of results5,935 incident ADC were diagnosed among 100,536 HIV1+ patients followed between 1992 and 2009. All ADC IRs were significantly reduced between pre‐ and post‐cART eras and continue to decline in the cART period (p<10−4). SIR are presented in the table.Median age at diagnosis was significantly younger among HIV1+ patients than the general population for KS (40.4 vs. 42.5; p<10−4), NHL (41.4 vs. 52.5; p<10−4) and CUC (39.3 vs. 42.5; p<10−4). For HIV1+ patients under treatment who maintained controlled viral load (<500 copies/µL) and CD4 ≥500/mm3 for at least 2 years, the risk for KS, NHL and CUC were respectively SIR=71.6 (28.7–147.5), 2.4 (0.9–4.8) and 1.6 (0.3–4.7) vs. general population.ConclusionsThe incidence rates of KS, NHL and CUC continued to decline through 2009 but the risk remained elevated as compared to general population in the most recent cART period. Despite the great reduction when compared to general population, the risk is still very high for KS in HIV1+patients who maintained CD4 ≥500/mm3 for at least 2 years. The risk was not significant for CUC and NHL.

Published: November 2012

AbstractA stretchable and transparent In‐Ga‐Zn‐O (IGZO) thin film transistors with high electrical performance and scalability is demonstrated. A load‐controlled roll transfer method is realized for fully automated and scalable transfer of the IGZO TFTs from a rigid substrate to a nonconventional elastomeric substrate. The IGZO TFTs exhibit high electrical performance under stretching and cyclic tests, demonstrating the potentiality of the load‐controlled roll transfer in stretchable electronics. The mechanics of the load‐controlled roll transfer is investigated and simulated, and it is shown that the strain level experienced by the active layers of the device can be controlled to well below their maximum fracture level during transfer.

Published: November 2012

AbstractDeveloping novel one‐dimensional (1D) luminescent nanostructures (e.g., nanowires and nanoribbons) is highly desired for enabling progress in nanophotonics and other emerging optical technologies. Previous studies on 1D luminescent nanostructures were mostly focused on elemental and binary semiconductor materials, the light emission of which originates from the radiative recombination of electrons and holes via either intrinsic states or extrinsic defect states. Herein, three kinds of ternary europium aluminate nanoribbons are reported that have localized Eu2+ luminescent centers and exhibit new compositions, new crystal lattice structures, and new luminescence properties and mechanisms. These three europium aluminate nanoribbons are: blue luminescent EuAl6O10 with a new composition and a new tetragonal lattice structure, green luminescent EuAl2O4 with a monoclinic lattice structure, and orange luminescent EuAl2O4 with a new hexagonal lattice structure and extremely large band width and Stokes shift of emission. These materials have promising applications as nanometer‐scale light generators and waveguides in nanophotonics and as light converting phosphors in warm white light‐emitting diodes.
Determination of Extractables and Leachables from Single‐Use Systems
Authors: Ding Weibing 
Published: November 2012

AbstractSingle‐use systems have been increasingly used in biopharmaceutical manufacturing processes. Despite their multitude of advantages, these plastic and elastomeric assemblies also draw concerns about chemical compounds that may migrate to finished products and impact product quality or safety. Evaluation of such extractables/leachables and their potential impact remains a challenge to many suppliers and end users. Based on extensive experience on filter extractables study, a practical and science‐based approach for determination of extractables/leachables from single‐use systems used in biomanufacturing has been developed. The general procedure is presented through a case study.
Cholesterol Screening and Management in Children and Young Adults Should Start Early—NO!
Authors: Schroeder Alan R. , Redberg Rita F. 
Published: November 2012

AbstractIn 2011, an expert panel from the National Heart, Lung, and Blood Institute released recommendations for universal lipid screening and treatment of high cholesterol in children. There is no evidence that universal screening will help children lead longer, healthier lives. These recommendations will, however, fuel the epidemic of overtreatment that is currently threatening our healthcare system and our patients.The authors have no funding, financial relationships, or conflicts of interest to disclose.
Slit/Robo‐mediated chemorepulsion of vagal sensory axons in the fetal gut
Authors: Goldberg David , Borojevic Rajka , Anderson Monique , Chen Jason J. , Gershon Michael D. , Ratcliffe Elyanne M. 
Published: November 2012

AbstractBackground: The vagus nerve descends from the brain to the gut during fetal life to reach specific targets in the bowel wall. Vagal sensory axons have been shown to respond to the axon guidance molecule netrin and to its receptor, deleted in colorectal cancer (DCC). As there are regions of the gut wall into which vagal axons do and do not extend, it is likely that a combination of attractive and repellent cues are involved in how vagal axons reach specific targets. We tested the hypothesis that Slit/Robo chemorepulsion can contribute to the restriction of vagal sensory axons to specific targets in the gut wall. Results: Transcripts encoding Robo1 and Robo2 were expressed in the nodose ganglia throughout development and mRNA encoding the Robo ligands Slit1, Slit2, and Slit3 were all found in the fetal and adult bowel. Slit2 protein was located in the outer gut mesenchyme in regions that partially overlap with the secretion of netrin‐1. Neurites extending from explanted nodose ganglia were repelled by Slit2. Conclusions: These observations suggest that vagal sensory axons are responsive to Slit proteins and are thus repelled by Slits secreted in the gut wall and prevented from reaching inappropriate targets.

Equarin is involved in cell adhesion by means of heparan sulfate proteoglycan during lens development
Authors: Song Xiaohong , Sato Yuya , Sekiguchi Kiyotoshi , Tanaka Hideaki , Ohta Kunimasa 
Published: November 2012

AbstractBackground: Adhesion molecules are known to be instructive for both development and differentiation. During lens differentiation, epithelial cells undergo vertical elongation, with the anterior and posterior tips of the elongating fiber cells sliding along the epithelium and capsule, respectively. These cellular processes are highly coordinated through cell adhesive interactions, actin cytoskeletal reorganization and contractile force generation. Alterations in extracellular matrix composition that interfere with these interactions can lead to defects that alter tissue morphogenesis and the state of differentiation. We have demonstrated that Equarin, which is a secreted molecule expressed in the equator region of the lens, plays an important role in chick lens fiber differentiation through fibroblast growth factor signaling. Results: Here, we explored the function of Equarin in chick lens cell adhesion. Equarin protein was expressed in the extracellular region of lens differentiating cells. We found that Equarin promoted lens cell adhesion through heparan sulfate proteoglycan. By biochemical analysis, we found that Equarin directly binds syndecan‐3, which displayed a similar expression pattern to Equarin. Overexpression of Equarin resulted in altered actin localization. Conclusions: Equarin is involved in cell adhesion during fiber differentiation and development. Developmental Dynamics 242:23–29, 2013. © 2012 Wiley Periodicals, Inc.

AbstractA tubular segmented‐in‐series (SIS) solid oxide fuel cell (SOFC) sub module for intermediate temperature (700–800 °C) operation was fabricated and operated in this study. For this purpose, we fabricated porous ceramic supports of 3 YSZ through an extrusion process and analyzed the basic properties of the ceramic support, such as visible microstructure, porosity, and mechanical strength, respectively. After that, we fabricated a tubular SIS SOFC single cell by using dip coating and vacuum slurry coating method in the case of electrode and electrolyte, and obtained at 800 °C a performance of about 400 mW cm–2. To make a sub module for tubular SIS SOFC, ten tubular SIS SOFC single cells with an effective electrode area of 1.1 cm2 were coated onto the surface of the prepared ceramic support and were connected in series by using Ag + glass interconnect between each single cell. The ten‐cell sub module of tubular SIS SOFC showed in 3% humidified H2 and air at 800 °C a maximum power of ca. 390 mW cm–2.

AbstractMouse models are important tools to decipher the molecular mechanisms of mammary carcinogenesis and to mimic the respective human disease. Despite sharing common phenotypic and genetic features, the proper translation of murine models to human breast cancer remains a challenging task. In a previous study we showed that in the SV40 transgenic WAP‐T mice an active Met‐pathway and epithelial‐mesenchymal characteristics distinguish low‐ and high‐grade mammary carcinoma. To assign these murine tumors to corresponding human tumors we here incorporated the analysis of expression of transcription factor (TF) coding genes and show that thereby a more accurate interspecies translation can be achieved. We describe a novel cross‐species translation procedure and demonstrate that expression of unsupervised selected TFs, such as ELF5, HOXA5 and TFCP2L1, can clearly distinguish between the human molecular breast cancer subtypes—or as, for example, expression of TFAP2B between yet unclassified subgroups. By integrating different levels of information like histology, gene set enrichment, expression of differentiation markers and TFs we conclude that tumors in WAP‐T mice exhibit similarities to both, human basal‐like and non‐basal‐like subtypes. We furthermore suggest that the low‐ and high‐grade WAP‐T tumor phenotypes might arise from distinct cells of tumor origin. Our results underscore the importance of TFs as common cross‐species denominators in the regulatory networks underlying mammary carcinogenesis.
Mineralization induction effects of osteopontin, bone sialoprotein, and dentin phosphoprotein on a biomimetic collagen substrate
Authors: Zurick Kevin M. , Qin Chunlin , Bernards Matthew T. 
Published: November 2012

AbstractNative bone tissue is composed of a matrix of collagen, noncollagenous proteins, and calcium phosphate minerals, which are primarily hydroxyapatite. The SIBLING (small integrin‐binding ligand, N‐linked glycoprotein) family of proteins is the primary noncollagenous protein group found in mineralized tissues. In this work, the mineralization induction capabilities of three of the SIBLING members, bone sialoprotein (BSP), osteopontin (OPN), and the calcium‐binding subdomain of dentin sialophosphoprotein, dentin phosphoprotein (DPP), are directly compared on a biomimetic collagen substrate. A self‐assembled, loosely aligned collagen fibril substrate was prepared, and then 125I‐radiolabeled adsorption isotherms were developed for BSP, OPN, and DPP. The results showed that BSP exhibited the highest binding capacity for collagen at lower concentrations, followed by DPP and OPN. However, at the highest concentrations, all three proteins had similar adsorption levels. The adsorption isotherms were then used to identify conditions that resulted in identical amounts of adsorbed protein. These substrates were prepared and placed in simulated body fluid for 5, 10, and 24 h at 37°C. The resulting mineral morphology was assessed by atomic force microscopy, and the composition was determined using photochemical assays. Mineralization was seen in the presence of all the proteins. However, DPP was seen to be the only protein that formed individual mineral nodules similar to those seen in developing bone. This suggests that DPP plays a significant role in the biomineralization process and that the incorporation of DPP into tissue engineering constructs may facilitate the induction of biomimetic mineral formation. © 2012 Wiley Periodicals, Inc.

Published: November 2012

AbstractEpigenetic regulation, has been very scarcely explored in familial breast cancer (BC). In the present study RASSF1A and RAR beta promoter methylation and miR17, miR21, miR 124, and let‐7a expression were investigated to highlight possible differences of epigenetic regulation between male and female familial BC, also in comparison with sporadic BC. These epigenetic alterations were studied in 56 familial BC patients (27 males and 29 females) and in 16 female sporadic cases. RASSF1A resulted more frequently methylated in men than women (76% vs. 28%, respectively, P = 0.0001), while miR17 and let‐7a expression frequency was higher in women than in men (miR17: 66% in women vs. 41% in men, P < 0.05; let‐7a: 45% in women vs. 15% in men, P = 0.015). RASSF1A methylation affected 27.6% of familial BC while 83% of familial cases showed high expression of the gene (P = 0.025); on the contrary, only 17% of familial BC presented RAR beta methylation and 55% of familial cases overexpressed this gene (P = 0.005). Moreover, miR17, miR21, and let‐7a resulted significantly overexpressed in familial compared to sporadic BC. RASSF1A overexpression (86% vs. 65%, P = 0.13) and RAR beta overexpression (57% vs. 32%, P = 0.11) were higher in BRCA1/2 carriers even if not statistical significance was reached. BRCA mutation carriers also demonstrated significant overexpression of: miR17 (93% vs. 35%, P = 0.0001), let‐7a (64% vs. 16%, P = 0.002), and of miR21 (100% vs. 65%, P = 0.008). In conclusion, the present data suggest the involvement of RASSF1A in familial male BC, while miR17 and let‐7a seem to be implied in familial female BC. J. Cell.

Inhibition of Tulane virus replication in vitro with RNA interference
Authors: Fan Qiang , Wei Chao , Xia Ming , Jiang Xi 
Published: November 2012

AbstractRNA interference (RNAi), a conserved mechanism triggered by small interfering RNA (siRNA), has been used for suppressing gene expression through RNA degradation. The replication of caliciviruses (CVs) with RNAi was studied using the Tulane virus (TV) as a model. Five siRNAs targeting the non‐structural, the major (VP1) and minor (VP2) structural genes of the TV were developed and the viruses were quantified using quantitative real time PCR (qPCR) and tissue culture infective dose (TCID50) assay. Treatment of the cells with siRNA 4 hr before viral inoculation significantly reduced viral titer by up to 2.6 logs and dramatically decreased viral RNA copy numbers and viral titers 48 hr post infection in four of the five siRNAs studied. The results were confirmed by Western blot, in which the major structural protein VP1 was markedly reduced in both the cells and the culture medium. Two small protein bands of the shell (S) and protruding (P) domains of the viral capsid protein were also detected in the cell lysates, although their role in viral replication remains unknown. Since the TV shares many biological properties with human noroviruses (NoVs), the successful demonstration of RNAi in TV replication would provide valuable information in control of acute gastroenteritis caused by human NoVs.

Published: November 2012

AbstractThere are about 400 million people with chronic hepatitis B virus (HBV) infection worldwide with a potential of adverse sequelae including hepatocellular carcinoma. Recent data have shown that the level of HBV DNA in serum or plasma of an infected person probably reflects more accurately the replicative activity of the virus and therefore may serve as a better maker for management of the infection. This study was designed to determine the rate of detection of HBV DNA in blood samples of patients with HBsAg positive in Nigeria in comparison with the HBe and anti‐HBe used widely as serological markers of infectivity. Plasma samples from 105 patients with HBsAg positive were tested for the presence of HBeAg and anti‐HBe using a commercial enzyme‐linked immunosorbent assay while plasma HBV DNA was quantified using the COBAS Amplicor HBV Monitor assay. Of the 105 HBsAg samples, 17 (16.2%) and 85 (81%) were positive for HBeAg and anti‐HBe, respectively, while 8 (7.6%) were negative for both HBeAg and anti‐HBe. HBV DNA was detected in 86 (81.9%) of the samples, out of which 15 (18.1%) and 67 (80.7%) were positive for HBeAg and anti‐HBe, respectively. HBV DNA was detected in 78.4% of the HBeAg negative samples and in all the eight samples that were negative for both HBeAg and anti‐HBe. The implication of these findings in the management of patients with HBV infection is compelling. J. Med. Virol. 85:214–218, 2013. © 2012 Wiley Periodicals, Inc.
