Oxygen toxicity contributes to the pathogenesis of adverse neurological outcome in survivors of preterm birth in clinical studies. In infant rodent brains, hyperoxia triggers widespread apoptotic neurodegeneration, induces pro-inflammatory cytokines and inhibits growth factor signaling cascades. Since a tissue-protective effect has been observed for recombinant erythropoietin (rEpo), we hypothe...
An extensive literature now supports a fundamental role for glutathione in the antioxidant protection of the lung and its gas exchange surface [1]. However, the physiological significance of lung glutathione turnover by the extracellular catabolic enzyme gamma-glutamyl transferase (GGT) has remained controversial. The function of GGT in the lung has been a major research focus in my laboratory....
background: role of nitric oxide (no) in morphine-induced conditioned place preference (cpp) has already been proposed in the rat medial septum (ms), but no molecular evidence has been provided to clear this fact. methods: effects of intraseptal injections of l-arginine and/or ng-nitro-l-arginine methyl ester (l-name) on morphine place conditioning in wistar rats were examined. morphine (2.5-7....
The major DNA adduct formed from the carcinogen ethylene dibromide (1,2-dibromoethane, EDB) is S-[2-(N7-guanyl)ethyl]glutathione, resulting from the reaction of guanyl residues with the half-mustard S-(2-bromoethyl)glutathione, which is generated by glutathione S-transferase-catalyzed conjugation of EDB with glutathione. The half-life of the alkylating species [putative S-(2-bromoethyl)glutathi...
Background: Electromagnetic fields were made by electromagnetic radiations (EMR) of mobile phone (radio-frequencies 900 MHz). Various researches have shown that there are relationships between mobile phone electromagnetic exposure and cancer and neurologic damages. The aim of our study was to investigate the effects of mobile phone electromagnetic radiations (radio-frequencies 900 MHz) on learn...
BACKGROUND The alterations of the glutathione peroxidase enzyme complex system occur in physiological conditions such as aging and oxidative stress consequent to strenuous exercise. METHODS Authors optimize the spectrophotometric method to measure glutathione peroxidase activity in rat red blood cell membranes. RESULTS The optimization, when applied to age paired rats, both nulligravid and ...
