in this study, we investigated the cardioprotective effects of resveratrol. rats were intraperitoneally administered with resveratrol (25 mg/kg bw) or vehicle (ethanol 10%) for 7 days and their heart subjected to ischemia/reperfusion injury. isolated hearts were langendorff perfused, left ventricular functions as heart rate and developed pressure, as well as, heart antioxidant status were deter...

Abstract This study was conducted to evaluate the role of oxidative stress in roots of eight wheat genotypes with different drought tolerance, subjected to drought stress. For analyzing the changes of antioxidant enzymes, native PAGE analyses of protein extract were performed. The roots of wheat seedlings showed one unambiguous isoform of superoxide dismutase (SOD) and catalase (CAT). Eight iso...

withania somnifera (l.) dunal is an erect evergreen shrub commonly known as ashwagandha. it is widely used in ayurvedic, and in the traditional pharmacopeia system of india. it is one of the major ingredients in many formulations prescribed for a variety of musculo-skeletal conditions including arthritis and rheumatism. in the present study, variations in the quality and quantity of proteins an...

background: withania somnifera l. dunal, (ashwagandha) belongs to the family solanaceae and is known as ‘indian ginseng’ in the traditional system of medicine. objectives: in the present investigation, comparative analysis was carried out between two different ecotypes of w. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (cat), superoxide dismutase (sod) an...

One of the most significant manifestations of environmental stress in plants is the increased production of Reactive Oxygen Species (ROS). These ROS, if allowed to accumulate unchecked, can lead to cellular toxicity. A battery of antioxidant molecules is present in plants for keeping ROS levels under check and to maintain the cellular homeostasis under stress. Ascorbate peroxidase (APX) is a ke...

The article presents the data of laboratory results on study effect phytoregulators changes in activity peroxidase enzyme isoforms dry seeds malting barley and during their germination. It was found that use grains increases isoforms.

Superoxide dismutase (SOD, EC 1.15.1.1) is an important metal-containing antioxidant enzyme that provides the first line of defense against toxic superoxide radicals by catalyzing their dismutation to oxygen and hydrogen peroxide. SOD is classified into four metalloprotein isoforms, namely, Cu/Zn SOD, Mn SOD, Ni SOD and Fe SOD. The structural models of soybean SOD isoforms have not yet been sol...
