Glutathione S-transferases (GSTs) play critical roles in detoxification, response to oxidative stress, regeneration of S-thiolated proteins, and catalysis of reactions in nondetoxification metabolic pathways. Liver GSTs were purified from the anoxia-tolerant turtle, Trachemys scripta elegans.

The study compared effects of different hypobaric hypoxia regimens (14% O2, 10.5% O2, and 8% O2; 1 hour; 15 days) on parameters of the glutathione system, intensity of free radical oxidation, and intensity of lipid peroxidation in cerebral cortex (CC) of rats with different, genetically

Pacu (Piaractus mesopotamicus Holmberg, 1887, Characiformes) dwells in waters of Pantanal, in which it has adapted for alternate concentrations of dissolved oxygen. Intracellular antioxidant protection should be vital for such an adaptation. Accordingly, we found that cytosol from liver of pacu has

Human cytochrome P450 2S1 was recently identified and shown to be inducible by 2,3,7,8-tetrachlorodibenzo-p-dioxin and hypoxia. It is highly expressed in epithelial cells of tissues that are exposed to the environment and in many tumors of epithelial origin. The biological function of CYP2S1 has not

OBJECTIVE Hypericum spp. (H.) has been used in traditional medicine for their sedative effect for many years. In spite of many works on this genus, little is known about H. scabrum. In this work antidepressant and its protective effect against hypoxia-induced lethality were

Nitric oxide (NO) is a multifunctional messenger in many vertebrates. In the liver, NO was found to play an important but controversial role in injury produced by toxins or sepsis. The purpose of the present investigation was to further characterize the role of NO in hepatocyte oxidative injury. A
