Movement of inorganic ions across the membrane of striated muscle.
The unidirectional fluxes of sodium, chloride, anid potassium across the mnembrane of striated muscle cells are described under a number of experiniental conditions. The results are compared with the predicted behavior of simple membranes. With the possible exception of chloride, it is concluded that the movements of these ions cannot be described without postulating variable permeabilities or ...

متن کاملa comparative pragmatic analysis of the speech act of “disagreement” across english and persian
the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...
15 صفحه اولThe Movement of Thallium Ions in Muscle
Measurements have been made of the fluxes of thallous ions (Tl(+)) across the membrane of frog sartorius muscle fibers. These show that at an external concentration of 74 microM the influx is about 270 x 10(-15) moles/cm.(2) sec., while the efflux from a muscle with an internal concentration equal to the above is 5 x 10(-15) moles/cm.(2) sec. The efflux is increased of the order of 300-fold dur...
متن کاملThe movement of ions and water across the cornea.
.he cornea performs its main optical function not directly by cellular activity but by the physicochemical arrangement of its inert collagen and mucopolysaccharides. The swelling of the ground substance largely determines whether the collagen fibrils are in their normal lattice arrangement, transparent to light, or whether this delicate alignment is distorted. Ultimately, the movement of water ...
