The antioxidant system in plants is a very important defensive mechanism to overcome stress conditions. We examined the expression profile of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) using a bioinformatics approach. We explored secondary structure prediction and made detailed studies of signature pattern of antioxidant proteins in four plant ...

Trifolium alexandrinum is traditionally used in various human ailments, including renal dysfunctions. The present experiment was designed to investigate antioxidant and nephroprotective effect of T. alexandrinum methanolic extract (TAME) against CCl4-induced oxidative stress in albino rats. Results of in vitro study revealed significant (P < 0.05) antioxidant effects. The ameliorative role of T...

the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...

To investigate the physiological responses of plants to high root-zone temperature (HT, 35 °C) stress mitigated by exogenous glutathione (GSH), cucumber (Cucumis sativus L.) seedlings were exposed to HT with or without GSH treatment for 4 days and following with 4 days of recovery. Plant physiological variables, growth, and gene expression related to antioxidant enzymes and Calvin cycle were qu...

The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams' E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 microM). Hepatocytes incubated in the MWE medium without cadmiu...

Inhibition of carcinogenesis may be a consequence of attenuation of oxidative stress via activation of antioxidant defence system, restoration and stabilization of tumour suppressor proteins along with modulation of inflammatory mediators. Previously we have delineated significant role of curcumin during its long term effect in regulation of glycolytic pathway and angiogenesis, which in turn re...

BACKGROUND Ginger is a natural dietary component with antioxidant and anti-carcinogenic properties. This study was conducted to evaluate the prophylactic effect of ginger extract on ethanol-induced reproductive toxicity in male rats by measuring the total homocysteine (tHcy), trace elements, antioxidant enzymes activity including glutathione peroxidase, superoxide dismutase (SOD) and catalase, ...

The stimulation of oxidative stress and lipid peroxidation of liver tissues by AFB1 has been extensively investigated. However, the effect of AFB1 on antioxidant enzyme activities and gene expression in testis has not been completely elucidated. The current study investigated the histopathological picture and activities in addition to gene expression of antioxidant enzymes in testis of rats int...

Background: The detrimental effects of persistent stimulation with hCG were investigated in rat Leydig cells in vitro. Materials and Methods: Oxidative stress parameters such as lipid peroxidation, Reactive oxygen species(ROS), Total antioxidant capcity (TAC) and activities of antioxidant enzymes were assessed in the treated cells. Apoptosis amongest the trearted cells were detected by in situ ...
