Volume Control by Muscle Fibers of the Blue Crab
Single isolated muscle fibers from the walking legs of the blue crab, Callinectes sapidus act as Boyle-van't Hoff osmometers with an osmotically inactive volume of 33 %. Fibers in hypotonic salines undergo a spontaneous volume readjustment toward the initial volumes of the cells found in isotonic salines. The volume readjustment is initiated by the increase in cell volume in hypotonic salines a...
متن کاملVolume Control by Muscle Fibers of the Blue Crab Volume readjustment in hypotonic salines
I N T R O D U C T I O N This study concentrates on a unique volume response of blue crab muscle fibers to hypotonic salines. When single fibers isolated from vertebrate muscle (Reuben et al., 1963; Blinks, 1965) or from invertebrate muscle (Reuben et al., 1964; Gainer and Grundfest, 1968) are placed into hypotonic salines, their volumes usually increase to new steady-state levels which remain c...

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 اولWater Permeability of Isolated Muscle Fibers of a Marine Crab
This report deals with the diffusional and nondiffusional water fluxes of muscle fibers of the crab, Chionoecetes bairdi. Graphical analysis of the deuterium exchange indicates that two fiber compartments exist for water. The first, comprising about 60-70% of the fiber water, probably represents the sarcoplasm which is bounded externally by the plasma membrane. The second compartment might repr...
متن کاملThe Equivalent Circuit of Single Crab Muscle Fibers As Determined by Impedance Measurements with Intracellular Electrodes
The input impedance of muscle fibers of the crab was determined with microelectrodes over the frequency range 1 cps to 10 kc/sec. Care was taken to analyze, reduce, and correct for capacitive artifact. One dimensional cable theory was used to determine the properties of the equivalent circuit of the membrane admittance, and the errors introduced by the neglect of the three dimensional spread of...
