Nucleotide sequences from a total of 421 HEV isolates were retrieved from Genbank and analysed. Phylogenetically, HEV was classified into four major genotypes. Genotype 1 was more conserved and classified into five subtypes. The number of genotype 2 sequences was limited but can be classified into two subtypes. Genotypes 3 and 4 were extremely diverse and(More)
RESEARCH DESIGN AND METHODS — Plasma 25(OH)D was measured in a crosssectional sample of 1,443 men and 1,819 women aged 50–70 years from Beijing and Shanghai. Metabolic syndrome was defined according to the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian Americans. Fasting plasma glucose, insulin, lipid profile,(More)
Members of the kinesin superfamily are microtubule-based motor proteins that transport molecules/organelles along microtubules. We have identified similar internal motor kinesins, Kinesin-13A, from the cotton Gossypium hirsutum and Arabidopsis thaliana. Their motor domains share high degree of similarity with those of internal motor kinesins of animals and(More)
To determine hepatitis C virus (HCV) genotype distribution in China, a total of 148 HCV RNA positive serum samples were collected from nine geographic areas and subjected to RT-PCR followed by direct DNA sequencing and phylogenetic analysis of the core, E1, and NS5B regions. HCV was genotyped in 139 (93.9%) samples. Among them subtype 1b was the most(More)
The hepatitis C virus (HCV), which currently infects an estimated 3% of people worldwide, has been present in some human populations for several centuries, notably HCV genotypes 1 and 2 in West Africa and genotype 6 in Southeast Asia. Here we use newly developed methods of sequence analysis to conduct the first comprehensive investigation of the epidemic(More)
BACKGROUND Recently in China, HCV 6a infection has shown a fast increase among patients and blood donors, possibly due to IDU linked transmission. METHODOLOGY/FINDINGS We recruited 210 drug users in Shanwei city, Guangdong province. Among them, HCV RNA was detected in 150 (71.4%), both E1 and NS5B genes were sequenced in 136, and 6a genotyped in 70. Of(More)
Common variants in KCNQ1 have recently been reported to be associated with type 2 diabetes in East Asians. We aimed to examine whether these common variants (rs2074196, rs2237892, rs2237895 and rs2237897) were also associated with type 2 diabetes in a population-based cohort of 3210 Chinese Hans and to explore the underlying mechanisms. The SNPs rs2237892,(More)
OBJECTIVES Recent genome-wide association studies have identified a number of variants influencing blood pressure. We aimed to examine whether these associations can be replicated in Chinese. METHODS We genotyped eight of these variants (in or near FGF5, CYP17A1, MTHFR, ZNF652, PLCD3, ATP2B1, c10orf107) in a population-based cohort of Chinese Hans (N =(More)
BACKGROUND Protective CD4+CD25+ regulatory T cells bearing the Forkhead Foxp3 transcription factor can now be divided into three subsets: Endogenous thymus-derived cells, those induced in the periphery, and another subset induced ex-vivo with pharmacological amounts of IL-2 and TGF-β. Unfortunately, endogenous CD4+CD25+ regulatory T cells are unstable and(More)
Substantial progress has been made in identification of type 2 diabetes (T2D) risk loci in the past few years, but our understanding of the genetic basis of T2D in ethnically diverse populations remains limited. We performed a genome-wide association study and a replication study in Chinese Hans comprising 8,569 T2D case subjects and 8,923 control subjects(More)
