Genetic variations have been thought to contribute to individual differences in lung cancer susceptibility. In our study, the possibility of an association of CYP1B1, GSTP1 and hOGG1 genetic polymorphisms with lung cancer was investigated in Chinese population of Nanjing, by a new single nucleotide polymorphism (SNP) typing approach of(More)
Development of gastric cancer is a multistage, multifactorial process. This study determined the population attributable risk for environmental and genetic risk factors in development of gastric cancer. A 1:1 cancer case-control study was undertaken in Nanjing, Jiangsu Province, China. A conditional-logistic regression model was used to determine(More)
As titanium dioxide (TiO(2)) nanoparticles are widely used commercially, the potential effects of TiO(2) nanoparticles on humans are a concern. To evaluate the effects of TiO(2) nanoparticles on hepatic and renal functions and correlate changes to oxidative stress, Sprague-Dawley rats were treated with TiO(2) particles of two different specific surface(More)
MicroRNAs (miRNAs) are postulated to play important roles in oncogenesis. Recently, extracellular miRNAs were detected in plasma or serum of diseased subjects. However, the role of circulating miRNAs in plasma/serum remains to be elucidated. In this study, the relative expressions of miR-155, miR-183, and miR-20a in esophageal tissue were found to be(More)
The increased application of carbon nanotubes (CNTs) has raised the level of public concern regarding possible toxicities. Using in vitro cellular assays, we were able to assess the immunotoxicity of pristine multi-wall carbon nanotubes (MWCNTs) and their derivatives, covalently functionalized with carboxyl (COOH) or polyethylene glycol (PEG), in rodent(More)
Microcystins are toxic peptides secreted by certain water blooms of toxic cyanobacteria. The most widely studied microcystin is microcystin-LR (MC-LR), which exhibits hepatotoxicity and neurotoxicity. However, limited information is available regarding the effects on offspring following maternal exposure. The present study was conducted to observe the(More)
Glutathione S-transferases (GST) belong to a superfamily of phase II enzymes believed to be associated with enhanced frequency of esophageal carcinoma. This study was performed to evaluate whether the GST family was associated with susceptibility to esophageal carcinoma in China. Ninety-seven patients with newly diagnosed, untreated esophageal squamous-cell(More)
This study aimed to isolate and characterize an indigenous algicidal bacterium named LTH-1 and its algae-lysing compounds active against three Microcystis aeruginosa strains (toxic TH1, nontoxic TH2 and standard FACHB 905). The LTH-1 isolated from Lake Taihu, near Wuxi City in China, was identified as Aeromonas sp. based on its morphological characteristic(More)
Single-chamber air-cathode microbial fuel cells (MFCs) were used to generate electricity from fermented primary sludge. Fermentation (30 °C, 9 days) decreased total suspended solids (26.1-16.5 g/L), volatile suspended solids (24.1-15.3g/L) and pH (5.7-4.5), and increased conductivity (2.4-4.7 mS/cm), soluble COD (2.66-15.5 g/L), and volatile fatty acids(More)
Carbon nanotubes have attracted attention not only due to electrical, optical, and mechanical applications but also due to their presence in biological and pharmaceutical products. In this study, modified multi-walled carbon nanotubes (MWCNT) were used as a model to evaluate potential subchronic effects of carbon nanotubes on mice. ICR mice were treated(More)
