5MicroRNA regulation of innate immune responses in epithelial cells显示文摘Mucosal surface epithelial cells are equipped with several defense mechanisms that guard against pathogens.Recent studies indicate that microRNAs(miRNAs)mediate post-transcriptional gene suppression and may be a critical component of the complex regulatory networks in epithelial immune responses.Transcription of miRNA genes in epithelial cells can be elaborately controlled through pathogen recognition receptors,such as Toll-like receptors(TLRs),and associated nuclear factor kappaB(NF-kB)and mitogen-activated protein kinase(MAPK)pathways,and ultimately nuclear transcription factor associated-transactivation and transrepression.Activation of these intracellular signaling pathways may also modulate the process of miRNA maturation.Functionally,miRNAs may modulate epithelial immune responses at every step of the innate immune network,including production and release of cytokines/chemokines,expression of adhesion and costimulatory molecules,shuttling of miRNAs through release of exosomes and feedback regulation of immune homeostasis.Therefore,miRNAs act as critical regulators to the fine-tuning of epithelial immune responses.Rui Zhou Steven P O’Hara Xian-Ming Chen 2011Cellular & Molecular Immunology2011,8,5:13

7A gene expression estimator of intramuscular fat percentage for use in both cattle and sheep显示文摘Background:The expression of genes encoding proteins involved in triacyglyceride and fatty acid synthesis and storage in cattle muscle are correlated with intramuscular fat(IMF)%.Are the same genes also correlated with IMF%in sheep muscle,and can the same set of genes be used to estimate IMF%in both species?Results:The correlation between gene expression(microarray) and IMF%in the longissimus muscle(LM) of twenty sheep was calculated.An integrated analysis of this dataset with an equivalent cattle correlation dataset and a cattle differential expression dataset was undertaken.A total of 30 genes were identified to be strongly correlated with IMF%in both cattle and sheep.The overlap of genes was highly significant,8 of the 13 genes in the TAG gene set and 8 of the 13 genes in the FA gene set were in the top 100 and 500 genes respertively most correlated with IMF%in sheep,P-value = 0.Of the 30 genes,CIDEA,THRSP,ACSM1,DGAT2 and FABP4 had the highest average rank in both species.Using the data from two small groups of Brahman cattle(control and Hormone growth promotant-treated[known to decrease IMF%in muscle]) and 22 animals in total,the utility of a direct measure and different estimators of IMF%(ultrasound and gene expression) to differentiate between the two groups were examined.Directly measured IMF%and IMF%estimated from ultrasound scanning could not discriminate between the two groups.However,using gene expression to estimate IMF%discriminated between the two groups.Increasing the number of genes used to estimate IMF%from one to five significantly increased the discrimination power;but increasing the number of genes to 15 resulted in little further improvement.Conclusion:We have demonstrated the utility of a comparative approach to identify robust estimators of IMF%in the LM in cattle and sheep.We have also demonstrated a number of approaches(potentially applicable to much smaller groups of animals than conventional methods) to using gene expression to rank animals for IMF%within a single farm/treatment,or to estimate differences in IMF%between two farms/treatments.Bing Guo Kritaya Kongsuwan Paul L Greenwood Guanghong Zhou Wangang Zhang Brian P Dalrymple 2014Journal of Animal Science and Biotechnology2014,5,4:6

10Human Immunodeficiency Virus Infection-Associated Mortality during Pulmonary Tuberculosis Treatment in Six Provinces of China显示文摘Objective To investigate the risk factors attributable to tuberculosis-related deaths in areas with human immunodeficiency virus(HIV) infection epidemics. Methods A prospective cohort study of newly registered patients in tuberculosis(TB) dispensaries in six representative Chinese provinces was conducted from September 1, 2009 to August 31, 2011. Risk factors for TB-associated death were identified through logistic regression analysis. Results Of 19,103 newly registered pulmonary TB patients, 925(4.8%) were found to be HIV-positive. Miliary TB and acid-fast bacillus smear-negative TB were more common among these patients. Out of a total of 322(1.7%) deaths that occurred during TB treatment, 85(26%) of the patients were co-infected with HIV. Multivariate analysis revealed that HIV infection was the strongest predictor of death [adjusted odds ratio(aO R) 7.86]. Other significant mortality risk factors included presentation with miliary TB(aO R 4.10; 95% confidence interval: 2.14-7.88), ≥35 years of age(aO R 3.04), non-Han ethnicity(aO R 1.67), and farming as an occupation(aO R 1.59). For patients with TB/HIV co-infection, miliary TB was the strongest risk factor for death(aO R 5.48). A low CD4 count(≤ 200 cells/μL)(aO R 3.27) at the time of TB treatment initiation and a lack of antiretroviral therapy(ART) administration(aO R 3.78) were also correlated with an increased risk of death. Conclusion Infection with HIV was independently associated with increased mortality during TB treatment. Offering HIV testing at the time of diagnosis with TB, early TB diagnosis among HIV/acquired immunodeficiency syndrome patients, and the timely provision of ART were identified as the key approaches that could reduce the number of HIV-associated TB deaths.LAI Yu Ji LIU Er Yong WANG Li Ming Jamie P MORANO WANG Ning Kaveh KHOSHNOOD ZHOU Lin CHENG Shi Ming 2015Biomedical and Environmental Sciences2015,28,6:4
11Improving Densification and Mechanical Properties of FeAl/TiC Composites by Addition of Ni显示文摘FeAl/TiC composites were fabricated by hot pressing blended elemental powders. The effects of Ni-doping on thedensification and mechanical properties of the composites were studied. Results show that the density of the com-posites decreases with the content of TiC increasing, and the addition of Ni significantly improves the densificationprocess by enhancing mass transfer in the bonding phase. The mechanical properties of the composites are closelyrelated with their porosity. Besides increasing the density of the composites, the addition of Ni improves the mechan-ical properties by other three effects: solution-strengthening the bonding phase, strengthening the FeAl-TiC interfaceand increasing ductile fracture in FeAl phase.Yong LIU, Fengxiao LIU, Baiyun HUANG, Kechao ZHOU, Yuehui HE and Zhihong TANGNational Key Lab for P/M, Central South University, Changsha 410083, China 2003Journal of Materials Science & Technology2003,19,1:4

15The conversion factor of K_(eff) to K_(3.7) in thermoluminescence dating显示文摘In the fine-grain TL dating the full o dose must be converted into the equivalent P dose. The conversion is finished by Keff-value, which is an effective or effectiveness. But the Keff can not be measured directly for each sample and only the external radiative efficiency K3.7 can be measured. In order to obtain the Keff a special study for the conversion factor of Keff to K3.t has been made using the ultrathin TLD. The results show that the conversion factor of tile TLD for archaeological samples is 0.847, which is in agreement with calculated value 0.85.Wang Wei-Da Zhou Zhi-Xin Xia Jun-Ding (Research Laborotory for Conservation and Archaeology, Shanghai Museum, Shanghai 200951)Leung P L Stokes M J(Department of Physics and Materials Science, City University of Hong Kong) 1998Nuclear Science and Techniques1998,9,4:3

17SEM in situ laboratory investigations on damage growth in GFRP composite under three-point bending tests显示文摘Glass fiber-reinforced polymer (GFRP) composites are widely used in low-weight constructions.SEM (scanning electron microscopy) in situ experiments of damage growth in GFRP composite under three-point bending loads are carried out.By summarizing the experimental results of three groups of samples with different orientation angles of fibers,the dependence of mechanical parameters on the orientation angles of fibers are analyzed.The regression analysis show that the peak strengths,the elastic strengths and the elastic modulus of the composites decease with the orientation angles of fibers almost linearly.Moreover,the damage growth and meso-scale structure changes in GFRP composites during three-point bending loading are analyzed.ZHOU HongWei MISHNAEVSKY Jr L BRONDSTED p TAN JinBiao GUI LeLe 2010Chinese Science Bulletin2010,55,12:3
18The Novel Mechanical Property of Tongue of a Woodpecker显示文摘Biomaterials such as bone,teeth,nacre and silk are known to have superior mechanical properties due to their specificnanocomposite structures.Here we report that the woodpecker’s tongue exhibits a novel strength and flexibility due to its specialcomposite micro/nanostructure.The tongue consists of a flexible cartilage-and-bone skeleton covered with a thin layer tissue ofhigh strength and elasticity.At the interface between the cartilage-and-bone skeleton and the tissue layer,there is a hierarchicalfiber-typed connection.It is this special design of the tongue that makes the woodpeckers efficient in catching the insects insidetrees.The special micro/nanostructures of the woodpecker’s tongue show us a potential method to enhance the interfacialconnection between soft and hard material layers for bio-inspired composite system designs.P Zhou X Q Kong C W Wu Z Chen 2009Journal of Bionic Engineering2009,6,3:3

20Fluorescence and SEM correlative microscopy for nanomanipulation of subcellular structures显示文摘Nanomanipulation under scanning electron microscopy(SEM)enables direct interactions of a tool with a sample.We recently developed a nanomanipulation technique for the extraction and identification of DNA contained within sub-nuclear locations of a single cell nucleus.In nanomanipulation of sub-cellular structures,a key step is to identify targets of interest through correlating fluorescence and SEM images.The DNA extraction task must be conducted with low accelerating voltages resulting in low imaging resolutions.This is imposed by the necessity of preserving the biochemical integrity of the sample.Such poor imaging conditions make the identification of nanometer-sized fiducial marks difficult.This paper presents an affine scale-invariant feature transform(ASIFT)based method for correlating SEM images and fluorescence microscopy images.The performance of the image correlation approach under different noise levels and imaging magnifications was quantitatively evaluated.The optimal mean absolute error(MAE)of correlation results is 68634 nm under standard conditions.Compared with manual correlation by skilled operators,the automated correlation approach demonstrates a speed that is higher by an order of magnitude.With the SEM-fluorescence image correlation approach,targeted DNA was successfully extracted via nanomanipulation under SEM conditions.Zheng Gong Brandon K Chen Jun Liu Chao Zhou Dave Anchel Xiao Li Ji Ge David P Bazett-Jones Yu Sun 2014Light(Science & Applications)2014,3,1:2
