We studied here the short-term toxicity effects of Cd on the oxidative state and cell death in the gill of freshwater crab Sinopotamon henanense. Crabs were exposed to Cd that resulted in Cd accumulation and a significant increase in the metallothionein (MT) level in the gill, but MT level increased disproportionally compared to the Cd accumulation with an(More)
Cadmium (Cd) is a well-known toxic heavy metal that accumulates in the aquatic environment. Cd has been reported to induce oxidative damage and apoptosis. We investigated the regulation mechanism of hydrogen peroxide (H(2)O(2)) on Cd-induced apoptosis. We show that in the gills of the freshwater crab Sinopotamon henanense Cd induced apoptosis, in a time-(More)
A series of pentacyclic triterpene 3β-ester derivatives were designed, synthesized and evaluated as a new class of cholesteryl ester transfer protein (CETP) inhibitors for the treatment of dyslipidemia. In vitro screening assay showed that 5 out of 30 compounds displayed moderate inhibiting human CETP activity with IC50s less than 10 μM. Among them,(More)
Hydrogen sulfide is a common odor gas of volatile sulfur-containing compound. The emission of hydrogen sulfide in the waste gas from industrial processing and agricultural operations could cause air pollution to the surrounding environment. The aim of this study was screening and isolation of wild yeast strains from the sludge of sewage pool in the fishmeal(More)
