Calcium uptake by vesicles in a highly enriched sarcolemma preparation from canine ventricle was found to be markedly stimulated by intravesicular calcium. Stimulation of calcium uptake appeared to be a saturable function of intravesicular calcium. Calcium efflux from the vesicles was stimulated by calcium in the reaction medium. Calcium uptake, supported by intravesicular calcium, and calcium ...

The sodium-calcium exchanger was localized in tissue sections of canine kidneys with two different polyclonal antisera raised against purified sodium-calcium exchanger protein derived from dog cardiac sarcolemma. The sodium-calcium exchanger was prominent in the basolateral plasmalemma of the majority of cells in all connecting tubules. In contrast, it was observed rarely and inconspicuously ov...

debaryomyces hansenizopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by ulocladium. chartarum(pr.) simm. the ability of d. hansenii to prevent infection of u. chartarum was lost when the antagonist cells were killed by autoclaving. cell free culture filtrates of antagonist were unable to prevent disease incidence. efficacy ...

BACKGROUND The average dietary sodium intake of Koreans is 2.6 times higher than the World Health Organization's recommended amount. The effect of a diet high in sodium on the skeletal system, especially osteoporosis, has not previously been examined in Korean postmenopausal women with low bone mass. We assessed the daily sodium intake, and determined the impact of sodium intake on urinary calc...

It has been reported that calcium intake may effectively modulate the expression of hypertension affected by sodium. The present study extends our previous analysis of this calcium-sodium interaction, additionally demonstrating that calcium, sodium, and alcohol intake further contribute to both systolic and diastolic blood pressures in normotensive subjects. Calcium intake was related to lower ...

Experiments were performed on the lobster giant axon to determine the relation between intracellular spike amplitude and external calcium ion concentration. Action potential decline in low external calcium is greatly accelerated by simultaneous removal of external sodium ion. Correlation of the time course of spike decline in low calcium-low sodium solution with the time courses of spike declin...

In this study, a gel/liquid interface is utilized for growing new (calcium-phosphate)/carrageenan garden. The hydrogels are made from carrageenan loaded with either sodium phosphate or calcium chloride, while the interfaced solution contains source of salt not used in (i. e. sodium-phosphate hydrogel calcium-chloride and vice versa). physical chemical properties tubes grown both systems same am...

pure submandibular saliva was collected from anaesthetized vitamin - a - treated and control rats with using of pilocarpine as secretogogue, and then the serum was collected by cardiac puncutre. intraperitoneal injection of a large single dose (100,000 iu/kg) of vitamin a changed total protein, calcium and sodium concentrations of saliva so that sodium level of submandibular saliva was reduced ...
