Salinity is considered a global threat to agriculture and causes significant reduction in crop yield. In particular, salinity stress promotes reactive oxygen species (ROS) accumulation ionic imbalance cells, leading oxidative even cell death. A large number of genes which are involved defense, hormone, carbohydrate metabolic pathways down-regulated under stress. Plants respond through series ph...

Reactive oxygen species (ROS)plays an important role in sperm motility. The physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. Meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

The inhibitory effects of several steroids on G6PD activity using intact erythrocytes are reported. Incubation of whole blood with dehydroepiandrosterone (DHEA) resulted in 42% and 12% inhibition in the enzyme activity in the presence and absence of oxygen, respectively. Addition of epinephrine and/or aminophylline into the incubation medium caused further enzyme inhibition suggesting a po...
