Control of erythrocyte shape by calmodulin
Erythrocytes are deformable cells whose shapes can be altered by treatments with a variety of drugs. The forms the erythrocyte may assume vary continuously from the spiny "echinocytes" or crenated cells at one extreme to highly folded and dented "cupped" cells at the other extreme. Examination of 39 compounds for cup-forming activity revealed a remarkable correlation between their ability to fo...

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 اولCalmodulin Interactions with Erythrocyte Membranes
Two new vascular smooth muscle relaxants, bepridil and cetiedil, were found to possess specific CaM-inhibitory properties which resembled those of trifluoperazine. Trifluoperazine, bepridil, and cetiedil inhibited Ca2+-dependent '251-CaM binding to erythrocyte membranes and CaM activation of membrane Ca2+-ATPase with IC50 values of -12, 17, and -40 MAM, respectively. This does not appear to be ...
متن کاملAssessment of erythrocyte shape by flow cytometry techniques.
BACKGROUND Red blood cell (RBC) rheology is altered in different diseases, including acute conditions such as patients in intensive care units (ICU) with sepsis or with an inflammatory reaction due to postoperative states or intracerebral haemorrhage, or chronic conditions such as diabetes mellitus or terminal renal failure. Several techniques are available to assess alterations in RBC rheology...
متن کاملActivation of human erythrocyte Ca2+-dependent Mg2+-activated ATPase by calmodulin and calcium: quantitative analysis.
The effect of Ca2+ and calmodulin on (CaM) on the activation of Ca2+-dependent Mg2+-activated ATPase (Ca2+,Mg2+-ATPase; ATP phosphohydrolase, EC 3.6.1.3) has been carried out because of the finding that the CaM dependence of the activation varies with the concentration of free Ca2+, similarly to brain phosphodiesterase and adenylate cyclase. The study was carried out in the absence of chelating...
