Calcium, Calcium Translocation, and Specific Calcium Antagonists
1978It is now almost one hundred years since Sidney Ringer (1882) described the importance of Ca2+ in the maintenance of frog heart contractility. Subsequent to this observation, it has been increasingly recognized that Ca2+ plays a critical and central role in a multitude of biological events at both the intra-and extracellular levels (Duncan, 1976 ...

Glia, 1993
AbstractThis review summarizes current knowledge relating intracellular calcium and glial function. During steady state, glia maintain a low cytosolic calcium level by pumping calcium into intracellular stores and by extruding calcium across the plasma membrane. Glial Ca2+ increases in response to a variety of physiological stimuli.

NeuroMolecular Medicine, 2006
Intracellular calcium ([Ca2+]i) is highly regulated in eukaryotic cells. The free [Ca2+]i is approximately four orders of magnitude less than that in the extracellular environment. It is, therefore, an electrochemical gradient favoring Ca2+ entry, and transient cellular activation increasing Ca2+ permeability will lead to a transient increase in [Ca2 ...

Journal of the American College of Nutrition, 1989
In normal individuals, 1,25-dihydroxyvitamin D (1,25-D) levels regulate calcium (Ca) absorption according to Ca intake; its synthesis is stimulated by low Ca intake, probably via increased parathyroid hormone (PTH) secretion, to increase Ca absorption, and suppressed during high intake to reduce Ca absorption.
