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)
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)
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)
The objective of the present study was to demonstrate the anti-inflammatory and antinociceptive properties of agaricoglycerides of the fermented mushroom of Grifola frondosa (AGF). The effects of AGF on interleukin-1β (IL-1β) levels, tumor necrosis factor-α (TNF-α) levels, nuclear factor kappa B (NF-κB) levels, intercellular adhesion molecule-1 (ICAM-1)(More)
Minocycline has been shown to protect against myocardial ischemia and reperfusion injury. However, the mechanism remains unclear. This study was to investigate the role of high mobility group box 1 protein (HMGB1) in the cardioprotection of minocycline during myocardial ischemia and reperfusion in rats. Anesthetized male rats were once treated with(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)
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)
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 microg/g. At the concentration of 0.4%, the vanadium-associated toxicity was reduced, and its(More)
In vivo, cardiomyocytes are exposed to multiple biochemical and physical cues including topographical and electrical cues. During prolonged in vitro cultivation in standard tissue culture set-ups, cardiomyocytes are known to de-differentiate due to the lack of appropriate micro-environmental cues. Most currently available cell culture systems provide only a(More)
AIMS The atrial potential duration (APD) restitution has been suggested to play an important role in ventricular fibrillation; however, its role in atrial fibrillation (AF) has not been determined. This study sought to investigate the APD restitution properties in two different AF models: vagally mediated AF and 6-h rapid atrial pacing-induced AF. METHODS(More)
