The characteristics and sources of organic carbon (OC) and elemental carbon (EC) in PM(2.5) in 2006-2007 as well as their impact on the formation of heavy haze in Shanghai were investigated. Daily average concentrations of OC and EC ranged from 1.8 to 20.1 μg m(-3) and 0.5-7.8 μg m(-3) with averages of 7.2 and 2.8 μg m(-3), respectively. The carbonaceous(More)
In comparison to conventional marker-assisted selection (MAS), which utilizes only a subset of genetic markers associated with a trait to predict breeding values (BVs), genome-wide selection (GWS) improves prediction accuracies by incorporating all markers into a model simultaneously. This strategy avoids risks of missing quantitative trait loci (QTL) with(More)
This study was designed to identify the inhibitory effect of curcumin on ox-LDL-induced monocyte chemoattractant protein-1 (MCP-1) production and investigated whether the effects are mediated by mitogen-activated protein kinase (MAPK) and NF-κB pathways in rat vascular smooth muscle cells (VSMCs). The VSMCs cells were pretreated with curcumin, before(More)
Impacts of population structure on the evaluation of genomic heritability and prediction were investigated and quantified using high-density markers in diverse panels in rice and maize. Population structure is an important factor affecting estimation of genomic heritability and assessment of genomic prediction in stratified populations. In this study, our(More)
Fifty-five surface sediment samples covering virtually the entire Bohai Sea (Bohai) were analyzed for organochlorine pesticides (OCPs), in order to provide the extensive information of recent occurrence levels, distribution, possible sources and potential biological risk of these compounds in this area. Concentrations of total(More)
Fifty-four surface sediments covering the whole water body of the Bohai Sea in North China were collected and analyzed for PBDEs and PCBs, to acquire information about their levels, distributions and possible sources. The results show that BDE 209 is the predominant congener with a mean value of 7000 pg g(-1) dry weight, two orders of magnitude higher than(More)
We performed a genome-wide association study of esophageal squamous cell carcinoma (ESCC) by genotyping 1,077 individuals with ESCC and 1,733 control subjects of Chinese Han descent. We selected 18 promising SNPs for replication in an additional 7,673 cases of ESCC and 11,013 control subjects of Chinese Han descent and 303 cases of ESCC and 537 control(More)
DNA2, a helicase/nuclease family member, plays versatile roles in processing DNA intermediates during DNA replication and repair. Yeast Dna2 (yDna2) is essential in RNA primer removal during nuclear DNA replication and is important in repairing UV damage, base damage, and double-strand breaks. Our data demonstrate that, surprisingly, human DNA2 (hDNA2) does(More)
Monocyte chemoattractant protein 1 (MCP-1) is a CC chemokine which stimulates mononuclear leukocytes and is significant in the pathogenesis of inflammatory disease. Curcumin, extracted from Curcumae longae, has been shown to possess anti-inflammatory activity, in inflammation associated with the induction of MCP-1 expression. However, the underlying(More)
Genome-wide association studies have identified susceptibility loci for esophageal squamous cell carcinoma (ESCC). We conducted a meta-analysis of all single-nucleotide polymorphisms (SNPs) that showed nominally significant P-values in two previously published genome-wide scans that included a total of 2961 ESCC cases and 3400 controls. The meta-analysis(More)
