OBJECTIVE: We postulated that calcium supplementation of calcium-deficient pregnant women would lower vascular resistance in uteroplacental and fetoplacental circulations.

Transverse tubule vesicles isolated from frog skeletal muscle display sodium-calcium exchange activity, which was characterized measuring 45Ca influx in vesicles incubated with sodium. The initial rates of exchange varied ...

Objetivo: Determinar el efecto de la administración oral de calcio en adolescentes embarazadas de bajo nivel socioeconómico sobre las concentraciones de calcio ionizado plasmático y libre intracelular. Métodos: En un ...

Ca2+ oscillations are one of the most important signals within the cell. The mechanism for generation of Ca2+ oscillations is still not yet fully elucidated. We studied the role of capacitative Ca2+ entry (CCE) on intracellular ...

We studied the influence of muscarinic and nicotinic stimulation on both phosphoinositide metabolism and intracellular calcium levels in rat skeletal muscle primary cultures. Both nicotine and muscarine induced an increase ...
