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...

Social relationships protect against the development of stress-related psychiatric disorders, yet little is known about the neurobiology that regulates this phenomenon. Recent evidence suggests that oxytocin (OT), a neuropeptide involved in social bond formation, may play a role. This experiment investigated the effects of chronic intranasal OT administration on acute stress-induced hypothalami...

where rv is the yield stress and b is a constant. For this reason, data in the low shear region are conveniently plotted with the ordinate scale proportional to the square root of shear stress and the abscissa scale proportional to the square root of shear rate. Nearly straight lines result, the ordinate intercept of which is the yield stress. The yield stress is that value of shear stress belo...

Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated wi...

Halophytes have demonstrated their capability to thrive under extremely saline conditions and thus considered as one of the best germplasm for saline agriculture. Salinity is a worldwide problem, and the salt-affected areas are increasing day-by-day because of scanty rainfall, poor irrigation system, salt ingression, water contamination, and other environmental factors. The salinity stress tole...
