در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولAcute increases of renal medullary osmolality stimulate endothelin release from the kidney.
Experiments conducted in vitro suggest that high osmolality stimulates endothelin production and release by renal tubular epithelial cells. Whether hyperosmotic solutions exert similar effects in vivo is unknown. Therefore, we tested the hypothesis that increasing renal medullary osmolality enhances urinary excretion of endothelin in anesthetized rats. Isosmotic NaCl (284 mosmol/kgH(2)O) was in...
متن کاملRenin release responses to acute alterations in renal arterial osmolarity.
YOUNG, DAVID B., AND HOWARD H. ROSTTORFER. Renin releass responses to acute alterations in renal arterial osmolarity. Am. J. Physiol. 225(5): 1009-1014. 1973.-Renal arterial plasma osmolarity (RAPO) of anesthetized dogs was raised by renal arterial infusion of small volumes of hypertonic solutions of NaCI, dextrose, or urea. The infusions increased RAP0 by a mean (&SE) of 44.6 & 2.5 mOsm/liter ...
متن کاملLoss of renal medullary endothelin B receptor function during salt deprivation is regulated by angiotensin II.
We have recently demonstrated that chronic infusion of exogenous ANG II, which induces blood pressure elevation, attenuates renal medullary endothelin B (ET(B)) receptor function in rats. Moreover, this was associated with a reduction of ET(B) receptor expression in the renal inner medulla. The aim of this present work was to investigate the effect of a physiological increase in endogenous ANG ...
متن کاملNeural control of renal medullary perfusion.
There is strong evidence that the renal medullary circulation plays a key role in long-term blood pressure control. This, and evidence implicating sympathetic overactivity in development of hypertension, provides the need for understanding how sympathetic nerves affect medullary blood flow (MBF). The precise vascular elements that regulate MBF under physiological conditions are unknown, but lik...
