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)
Fusobacterium nucleatum is a gram-negative anaerobe ubiquitous to the oral cavity. It is associated with periodontal disease. It is also associated with preterm birth and has been isolated from the amniotic fluid, placenta, and chorioamnionic membranes of women delivering prematurely. Periodontal disease is a newly recognized risk factor for preterm birth.(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 structural and functional effects of fine-textured matrices with sub-micron features on the growth of cardiac myocytes were examined. Electrospinning was used to fabricate biodegradable non-woven poly(lactide)- and poly(glycolide)-based (PLGA) scaffolds for cardiac tissue engineering applications. Post-processing was applied to achieve macro-scale fiber(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)
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)
Microcystin-LR (MC-LR) is a widely studied toxic peptide secreted by certain water blooms of cyanobacteria that exhibit hepatotoxicity and neural toxicity. This study aimed to observe the neurotoxic effects of low-dose MC-LR exposure by oral administration. Male Sprague-Dawley (SD) rats were administered orally every 2 days for 8 weeks with pure water and(More)
