one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of  superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...

introduction: the fate of xenobiotics that is present, increasing day by day. the increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. methods: the present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by panax ginseng ...

The physiological status of poultry can be disturbed by different stressors that may lead to oxidative stress conditions. Oxidative activates defense systems, which mitigates the adverse effects. Several lines system exist, including enzyme systems such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and non-enzymatic antioxidants Glutathione (GSH). Methionine—a vit...

Salinity is one of the major constraints reducing plant growth and yield. Irrigation with poor quality brackish water to orchards a cause stunted low The salt tolerance mechanism complicated genomic characters that very problematic develop in fruit trees becomes much more severe at any developmental stage. Osmotic stress hormonal imbalances are causing biomass production. Fruit tree tolerance/s...

background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...

The mammalian glutathione peroxidase (GPx) family is a key component of the cellular antioxidative defence system. Within this family, GPx4 has unique features as it accepts a large class of hydroperoxy lipid substrates and has a plethora of biological functions, including sperm maturation, regulation of apoptosis and cerebral embryogenesis. In this paper, the structure of the cytoplasmic isofo...

Background: Psoriasis is a chronic-relapsing inflammatory skin disorder, in whose pathogenesis oxidative stress is suggested to be involved. Among different enzymes that play a role in maintaining the cellular redox balance, we aimed to assess the alteration of glutathione peroxidase (GPX) activity in cutaneous lesions and its correlation with the disease severity, firstly, to support the possi...

Protection of nitrogenase against oxygen inactivation in diazotrophs involves numerous strategies. Glutathione is known to play an important role in scavenging oxyradicals in many living systems. The involvement of glutathione (reduced) (GSH), glutathione peroxidase (GPX) and glutathione reductase (GR) in the protection of nitrogenase in free living diazotrophs is reported here for the first ti...
