The metabolism of (75)Se-labeled SeO(3) (2-) and its conversion by intact rat erythrocytes in vitro to a form which complexes with Cd and plasma proteins were studied. By utilizing both excess SeO(3) (2-) and N-ethylmaleimide to lower erythrocyte reduced glutathione (GSH) concentrations, it was shown that the uptake and metabolism of SeO(3) (2-) were GSH-dependent, the probable intermediate bei...

Mountaintop removal-valley fill coal mining has been associated with a variety of impacts on ecosystem and human health, in particular reductions in the biodiversity of receiving streams. However, effluents emerging from valley fills contain a complex mixture of chemicals including metals, metalloids, and salts, and it is not clear which of these are the most important drivers of toxicity. We f...

Monosodium glutamate (MSG) has been recognized as flavor enhancer that adversely affects male reproductive systems. The present study was carried out to evaluate the potential protective role of vitamin E (vit E) or selenium against MSG induced oxidative stress and histopathological changes in testis tissues of rats. Mature male Wistar rats weighing 150-200 g BW were allocated to evenly twelve ...

We investigated possible conditions or drugs that might enhance the sensitivity of anti-mitotic drug-resistant cancer cells. We particularly focused on identifying mechanisms or drugs that could sensitize P-glycoprotein (P-gp)-overexpressing resistant KBV20C cancer cells. Our approach utilized repositioning drugs, which are already used in clinics, because once their sensitization mechanisms on...
