The coupling of ion and water flow through membrane channels is under dispute. Among all human aquaporins only aquaporin-6 exhibits ion channel activity. Whether aquaporin-6 functions also as a water channel cannot yet be determined with confidence. Similarly, a comparison of single-channel water permeabilities from ion channels and aquaporins suggests that ion channels may play a secondary rol...
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...
BACKGROUND/AIMS Cell membranes facilitate the transport of water, ions, and necessary nutrients by hosting a great variety of transport channels that have either a 'simple' pore-like structure or more complex architecture that is based on the utilization of specific receptors. The present study reveals the impact of AgNO3, a well-known inhibitor of water channel activity, on transport channels ...

Although water is an important nutrient, there are no recommended intake values. Here, water intake, energy intake, physical activity and water loss was measured over 1 week in summer and in winter. Subjects were healthy volunteers, forty-two women and ten men, mean age of 29 (SD 7) years and mean BMI 21.8 (SD 2.2) kg/m2. Water intake was measured with a 7 d food and water record. Physical acti...
The function of aquaporin (AQP) protein in transporting water is crucial for plants to survive in drought stress. With 47 homologues in tomato (Solanum lycopersicum) were reported, but the individual and integrated functions of aquaporins involved in drought response remains unclear. Here, three plasma membrane intrinsic protein genes, SlPIP2;1, SlPIP2;7 and SlPIP2;5, were identified as candida...
هدف : یکی از مهمترین عوامل موثر بر یادگیری و حافظه هورمونهای جنسی می باشند. هورمونهای جنسی از طریق گیرنده های اختصاصی در داخل سلول و یا گیرنده های غشاء سلولی اثرات خود را اعمال می کنند که گیرنده های غشایی آندروژنها اخیرا بسیار مورد توجه قرار گرفته است. از آنجا که هیپوکامپ نقش اساسی در یادگیری و حافظه فضایی دارد، مطالعه اثرات غیرژنومیک تستوسترون bsa- بر هیپوکامپ و بر یادگیری و حافظه فضایی با است...
this study was carried out to investigate the effect ofadministration of satureja khuzistanica essential oil (skeo) in drinking water on performance, lipid oxidation, activity of antioxidative enzymes and cholesterol content of thigh meat using 720 one-day-old ross 308 broiler chicks. the skeo was added into drinking water at zero (control-), 200, 300, 400 and 500 mg/l along with a treatment co...
MODELING THE EFFECT OF WATER ACTIVITY ON THERMAL RESISTANCE OF SALMONELLA IN WHEAT FLOUR By Danielle F. Smith Salmonella is able to survive in low-moisture environments, is known to be more heat resistant as product water activity decreases, and recently has been implicated in several outbreaks and/or recalls associated with low-moisture foods. Therefore, the specific objectives were to: (1) Ev...
