Plants are always exposed to abiotic and biotic stresses which can adversely affect their growth and development. As an important antioxidant, AsA plays a vital role in plant defence against damage caused by stresses. In this study, we cloned a tomato GDP-L-galactose phosphorylase-like (SlGGP-LIKE) gene and investigated its role in resistance to abiotic and biotic stresses by using antisense transgenic (AS) tomato lines. The AsA content in AS plants was lower than that in WT plants. Under chilling stress, the growth of AS plants was inhibited significantly, and they yielded higher levels of ROS, REC and MDA but demonstrated weaker APX activity than that shown by WT plants...

Regular exercise is promoted as a therapeutic strategy for age-associated endothelial dysfunction. Improvements in endothelial function are observed with endurance exercise in older men, but are diminished or absent in older women. This review examines the hypothesis that sex hormones modulate vascular adaptations to exercise training by influencing antioxidant defense systems, mitochondrial function, oxidative stress, and intracellular signaling.

Several physiological events in the brain are regulated by the endocannabinoid system (ECS). While synthetic cannabinoid receptor (CBr) agonists such as WIN55,212-2 act directly on CBr, agents like URB597, a fatty acid amide hydrolase (FAAH) inhibitor, induce a more "physiological" activation of CBr by increasing the endogenous levels of the endocannabinoid anandamide (AEA). Herein, we compared the pre- and post-treatment efficacy of URB597 and WIN55,212-2 on different endpoints evaluated in the toxic model produced by the mitochondrial toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice...

Recent results discovered the protective roles of methane (CH4) against oxidative stress in animals. However, the possible physiological roles of CH4 in plants are still unknown. By using physiological, histochemical and molecular approaches, the beneficial role of CH4 in germinating alfalfa seeds upon copper (Cu) stress was evaluated. Endogenous production of CH4 was significantly increased in Cu-stressed alfalfa seeds, which was mimicked by 0.39 mM CH4. The pretreatment with CH4 significantly alleviated the inhibition of seed germination and seedling growth induced by Cu stress...
