In October 2008 nine farrow-to-finish pig farms were visited in Shuangliu County in Sichuan Province, China. One farm was empty for one month but not cleaned after depopulation. Dust samples were collected at each farm and analysed for the presence of methicillin-resistant Staphylococcus aureus (MRSA). Dust samples from four farms were also analysed for the(More)
Bone mineral density (BMD), a diagnostic parameter for osteoporosis and a clinical predictor of fracture, is a polygenic trait with high heritability. To identify genetic variants that influence BMD in different ethnic groups, we performed a genome-wide association study (GWAS) on 800 unrelated Southern Chinese women with extreme BMD and carried out(More)
The nanomaterial graphene oxide (GO) has attracted explosive interests in various areas. However, its performance in biological environments is still largely unknown, particularly with regard to cellular response to GO. Here we separated the GO sheets in different size and systematically investigated size effect of the GO in response to different types of(More)
Dominant inheritance of osteogenesis imperfecta (OI) is caused by mutations in COL1A1 or COL1A2, the genes that encode type I collagen, and CRTAP, LEPRE1, PPIB, FKBP10, SERPINH1, and SP7 mutations were recently detected in a minority of patients with autosomal recessive OI. However, these findings have been mostly restricted to Western populations. The(More)
By using whole-exome sequencing, we identified a homozygous guanine-to-adenine transition at the invariant -1 position of the acceptor site of intron 1 (c.97-1G>A) in solute carrier organic anion transporter family member 2A1 (SLCO2A1), which encodes a prostaglandin transporter protein, as the causative mutation in a single individual with primary(More)
To investigate the diversity of viral flora, we used metagenomics to study the viral communities in a pooled faecal sample of 27 diarrhoeic piglets from intensive commercial farms in China. The 15 distinct mammalian viruses identified in the pooled diarrhoeic sample were, in order of abundance of nucleic acid sequence, Porcine epidemic diarrhea virus(More)
Duck enteritis virus (DEV) is a herpesvirus that causes an acute, contagious, and fatal disease. In the present article, we introduce a quantitative real-time polymerase chain reaction (PCR) assay for DEV DNA using TaqMan technology and a two-step protocol. It was confirmed to be rapid, sensitive, and specific for DEV detection. The primers and probe were(More)
AIM To study the effect of genistein (GST) on rabbit heart ischemia/reperfusion (I/R) injury. METHODS Rabbit heart I/R injury was induced by occluding the left anterior descending coronary artery for 45 min and reperfusing for 180 min. GST (1.0 mg/kg) was intravenously injected 5 min before heart ischemia. Hemodynamic data, infarct size, and(More)
To identify the susceptibility genes for osteoporotic fracture in postmenopausal Chinese women, a two-stage case-control association study using joint analysis was conducted in 1046 patients with nontraumatic vertebra, hip, or distal radius fractures and 2303 healthy controls. First, 113 single-nucleotide polymorphisms (SNPs) in 16 potential osteoporosis(More)
OBJECTIVE The aims of this study were as follows: 1) to evaluate the association of serum sclerostin with bone mineral density (BMD) and markers of bone metabolism in postmenopausal Chinese women and 2) to observe the relationships of single-nucleotide polymorphisms (SNPs) within the sclerostin (SOST) gene with serum sclerostin, BMD, and markers of bone(More)
