in this study the effect of nitric oxide synthesis inhibition on stress-induced gastric damage was evaluated in bile duel ligated, sham operated and unoperated rats. animals were injected intraperitoneally with ng-nitro-l-arginine methylester (l-name), 40 mglkg, l-argininc, 200 mg/kg or saline, 30 min before water-immersion stress. one hour after water immersion, the animals were killed and the...

conclusions regular consumption of various fresh fruits and vegetables, whole grains, legumes and beans, sprouts and seeds is an effective and safe way to meet all antioxidant requirements in physically active persons and athletes. results it seems that the best recommendations regarding antioxidants and exercise are having a balanced diet rich in natural antioxidants and phytochemicals. eviden...

Heat stress has long been recognised as a cause of subfertility in farm animals. The objectives of the present study were to elucidate the effect of heat stress on sperm function and involvement of the mitogen-activated protein kinase (MAPK) 14 signalling pathway. Spermatozoa incubated for 4 h at a physiological temperature (38.5°C) exhibited significantly (P<0.05) reduced motility, plasma memb...

objective(s): the object of the study is to examine the effects of δ9-tetrahydrocannabinol (thc) against oxidative stress in the blood and excretion of thc metabolites in urine of type 2 diabetic rats. materials and methods: the control (n=8), thc control (n=6), diabetes (n=8) and diabetes + thc (n=7) groups were created. type 2 diabetes was induced by nicotinamide (na, 85 mg/kg) + streptozotoc...

Adult Drosophila subjected to a variety of environmental stresses that induce classic Drosophila heat shock response simultaneously exhibit a rapid and significant rise in copia homologous transcripts. Levels of Drosophila Adh (alcohol dehydrogenase gene) and 18s ribosomal RNA were unaffected by environmental stress. Copia's ability to be induced by stress is correlated with the presence of seq...
