Constriction of the neonatal aorta by raised oxygen tension.
A preparation consisting of the great arteries around the heart from neonatal guinea pigs was perfused at constant flow by physiological saline solutions in a bath in which various gases (952 N2 + 5% CO2, air + 5% CO, and 95$ O2 + 5% CO2) were bubbled. The pressure drop across the aorta, including the preductal area, was recorded and the changes in resistance in response to these gas tensions w...

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 اولEffect of cyanide on oxygen tension-dependent mechanical tension in rabbit aorta.
We determined relationships between oxygen uptake and mechanical tension in isolated strips of rabbit aorta treated with various agonists; organ bath Poi was varied over the range 4-350 mm Hg, or cyanide (CN) was added to the organ bath in concentrations of from 8 x 10"' to 3 x 10" M. Oxygen tension-dependent mechanical tension changes were similar during contractions caused by norepinephrine a...

The Effects of L-Citrulline Pretreatment on the Isometric Tension of the Isolated Perfused Rat Aorta
Background: The achievement of an effective compound for prevention/treatment of hypertension with fewer complications has been of interest in recent years. OBJECTIVES: This study aimed to examine the effects of L-citrulline pretreatment on the tension of isolated rat aortic tissues precontracted by different vasoconstrictors. METHODS: Sixteen male Wistar rats (300-350g) were randomly divided i...
