The chronic effect of environmental methomyl on the antioxidant system in testis Nile tilapia (Oreochromis niloticus) and its recovery pattern was investigated. Tilapia were exposed to sublethal concentrations 0.2, 2, 20 200 ?gL?1 for 30 days thereafter moved methomyl-free water 18 days. Antioxidant levels testis, including glutathione peroxidase, catalase, glutathione-S-transferase, reductase,...
Glutathione was found in several dairy Lactococcus lactis strains grown in M17 medium. None of these strains was able to synthesize glutathione. In chemically defined medium, L. lactis subsp. cremoris strain SK11 was able to accumulate up to approximately 60 mM glutathione when this compound was added to the medium. Stationary-phase cells of strain SK11 grown in chemically defined medium supple...
Selenium participates in the antioxidant defense mainly through a class of selenoproteins, including thioredoxin reductase. Epigallocatechin-3-gallate (EGCG) is the most abundant and biologically active catechin in green tea. Depending upon the dose and biological systems, EGCG may function either as an antioxidant or as an inducer of antioxidant defense via its pro-oxidant action or other unid...
Understanding how pathogenic fungi adapt to host plant cells is of major concern to securing global food production. The hemibiotrophic rice blast fungus Magnaporthe oryzae, cause of the most serious disease of cultivated rice, colonizes leaf cells asymptomatically as a biotroph for 4-5 days in susceptible rice cultivars before entering its destructive necrotrophic phase. During the biotrophic ...
background: many studies have investigated the possible role of reactive oxygen species in the etiology and pathogenesis of rheumatoid arthritis (ra). the aim of this study was to investigate the activities of some antioxidants in ra patients. methods: in this case-control study, 59 ra patients and 60 healthy sex and age-matched controls were selected. vitamin e and beta-carotene were determi...
Background. Teucrium polium is used in Arab traditional medicine to treat liver diseases. Glutathione is an important intracellular antioxidant, and intrahepatic glutathione levels are depleted in liver diseases. Hypothesis and Aim. This investigation tested the hypothesis that aqueous extracts of T. polium maintains intracellular glutathione levels by augmenting glutathione peroxidase and glut...
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...
The present study was undertaken to evaluate glutathione and its related enzymes in beta-thalassaemia major and to elucidate the effect of splenectomy on glutathione metabolism. The study includes three groups, those are: healthy individuals (n= 35) taken as control, a group of beta-thalassaemia major children with intact spleen (n= 29) and a group of splenectomized beta-thalassaemia major chil...
background: hawthorn species decreases blood pressure and relaxes precontracted vessels. this study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension. methods: six groups of male sprague-dawley rats, each containing 6 to 8 rats, were studied. the groups comprised of...
