Osmotic Properties of Amphibian Muscles

Osmotic Properties of Amphibian Muscles

Changes in the volume of fiber water in hypotonic and hypertonic Ringer's solution were determined for the sartorius, stomach, and cardiac muscle of the frog using two methods. Loss of water in hypertonic solutions was nearly the same in all muscles, but swelling in hypotonic solutions was greatest in the sartorius, smallest in the heart. For the sartorius the deviation from the properties of a...

Osmotic Properties of Mitochondria

The osmotic behavior of rat liver mitochondria has been studied in a sucrose medium. The mitochondria behave like a two compartment system. One compartment is permeable to sucrose and has a volume of 1.22 microl/(mg mitochondrial dry weight) in a 272 milliosmol sucrose medium; the second, inaccessible to sucrose, has a volume of 0.555 microl/mg dry weight) under the same conditions. Part of the...

control of the optical properties of nanoparticles by laser fields

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...

Cell surface properties of amphibian embryonic cells.

Gastrula and neurula embryos of Cynops pyrrhogaster were dissociated into cell suspensions with ethylenediaminetetraacetic acid (EDTA), trypsin, and solution. The cells were cultured in Niu-Twitty's balanced salt solution and their aggregates were examined histologically. The results indicated that the capacity of amphibian embryonic cells for aggregate formation, sorting out, and notochord dif...
