OBJECTIVES The purpose of this study was to examine the effects of noise exposure on spatial learning and memory and associated mechanisms in the hippocampus (HIP). METHODS Forty-eight male SD rats were grouped as: A, control; B, Morris water maze (MWM) training group; C, noise exposure group; and D, noise exposure followed by MWM training group. The(More)
The Vanadium uptake by Coprinus comatus and their co-effect on hyperglycemic mice were studied. By fermentation and AAS analysis, the optimal concentration of vanadium in medium was 0.4%, and the content of vanadium accumulated in the mycelia was 3,528.0 μg/g. At the concentration of 0.4%, the vanadium-associated toxicity was reduced, and its anti-diabetic(More)
BACKGROUND High mobility group box 1 (HMGB1) protein has been identified as a novel pro-inflammatory cytokine in coronary artery disease (CAD). We investigated the relationship between serum HMGB1 level and the severity of coronary artery stenosis. METHODS Serum HMGB1 concentration in patients was measured by ELISA. All patients underwent coronary(More)
A comparison of vanadium-rich activity of three species fungi of Basidiomycetes, Ganoderma lucidum, Coprinus comatus, and Grifola frondosa, was studied. By fermentation and atomic absorption spectroscopy analysis, the biomass of G. lucidum and G. frondosa declined rapidly when the concentration of vanadium exceeded 0.3% but the biomass of C. comatus did not(More)
High mobility group box 1 protein (HMGB1) plays an important role in myocardial ischemia and reperfusion (I/R) injury. Ethyl pyruvate (EP), a potent reactive oxygen species scavenger, has been reported to inhibit myocardial apoptosis and reduce myocardial I/R injury. The aim of this study was to investigate the mechanism by which EP reduces myocardial I/R(More)
Cardiovascular disease (CVD) is a leading cause of death and disabilities worldwide. Peroxisome proliferator-activated receptor gamma (PPARgamma) agonists possess potent anti-inflammatory actions and have recently emerged as potential therapeutic agents for CVD. Here we show that H2O2 induced apoptosis in cardiomyocytes with a marked down-regulation of(More)
Seed metabolites are critically important both for plant development and human nutrition; however, the natural variation in their levels remains poorly characterized. Here we profiled 121 metabolites in mature seeds of a wide panel Oryza sativa japonica and indica cultivars, revealing correlations between the metabolic phenotype and geographic origin of the(More)
The organization of cells and extracellular matrix (ECM) in native tissues plays a crucial role in their functionality. However, in tissue engineering, cells and ECM are randomly distributed within a scaffold. Thus, the production of engineered-tissue with complex 3D organization remains a challenge. In the present study, we used contact guidance to control(More)
OBJECTIVE To study the effect of chronic noise exposure on expression of N-methyl-D-aspartic acid receptor 2B (NR2B) and tau phosphorylation in hippocampus of rats. METHODS Twenty-four male SD rats were divided in control group and chronic noise exposure group. NR2B expression and tau phosphorylation in hippocampus of rats were detected after chronic(More)
High altitude illnesses pose health threats to unwary travelers after their acute ascent to high altitude locations. The incidence of high altitude illnesses among unacclimatized persons who acutely ascend to Tibet has not been previously reported. In the present study, we surveyed the incidence of high altitude illness among 3628 unacclimatized persons who(More)
