Calcium binding to fluorescent calcium indicators: Calcium green, calcium orange and calcium crimson
Biochemical and Biophysical Research Communications, 1991The recently introduced fluorescent calcium sensitive indicators calcium green, calcium orange and calcium crimson suggest important improvements and advantages to detect small calcium transients at low indicator concentrations. Thermodynamic dissociation constants and dissociation rate constants of calcium green, calcium orange and calcium crimson ...

Calcium entry in the calcium paradox
Journal of Molecular and Cellular Cardiology, 1981Abstract In this review the mechanisms that are involved in the aetiology of the Ca2+ paradox are discussed, with particular reference to the route and consequences of the massive influx of Ca2+ that occurs during the phase of Ca2+ repletion. The precise route of Ca2+ entry is unknown and it may be abnormal. The voltage activated slow channels do not

Calcium Requirement and Calcium Therapy
Clinical Orthopaedics and Related Research, 1979The mean calcium requirement of normal adults has been estimated from 212 calcium balances on 84 normal subjects and found to be 578 mg. The calcium allowance required to ensure that 95% of normal adults are in calcium balance is about 900 mg. Calcium requirement is relatively higher than that of phosphorus or magnesium because plasma calcium--and ...

Calcium, calcium channels, and calcium channel antagonists
Canadian Journal of Physiology and Pharmacology, 1990Voltage-dependent Ca2+ channels are an important pathway for Ca2+ influx in excitable cells. They also represent an important site of action for a therapeutic group of agents, the Ca2+ channel antagonists. These drugs enjoy considerable use in the cardiovascular area including angina, some arrhythmias, hypertension, and peripheral vascular disorders ...

Current Opinion in Chemical Biology, 1998
Ca2+ is involved in an intriguing variety of different biological events. The rapid development of techniques such as region- or organelle-directed fluorescent probes and laser scanning confocal microscopy for studying cellular biological events at a molecular level provides us with a rich daily intake of new results.

Emergency Medicine Clinics of North America, 1986
Disorders of calcium homeostasis are frequent and seldom diagnosed in the Emergency Department. In both the adult and pediatric population, the causes of increased or decreased calcium are many, and the index of suspicion needs to be raised for these disorders.

Atherogenesis, calcium and calcium antagonists
The American Journal of Cardiology, 1990Hypercholesterolemia and arterial hypertension are highly interrelated risk factors of atherosclerosis. Early lesions in nonhuman primates with dietary hypercholesterolemia resemble atherosclerotic lesions demonstrable in the arteries of American children with comparably elevated plasma cholesterol levels.

Calcium absorption and calcium bioavailability
Journal of Internal Medicine, 1992Calcium is important for bone health. It has been customary to focus on dietary calcium intake, but of central importance for the body needs in the individual patient is the actual calcium absorption. This absorption consists of an active vitamin D‐mediated component and a passive diffusional component.

CALCIUM NEED AND CALCIUM UTILIZATION
Journal of the American Medical Association, 1933In 1911, Sherman1called attention to the calcium deficiency of the average American dietary. Again, after twenty years, he2stated that "probably a larger proportion of the ordinary dietaries, both of adults and of children, can be improved by enrichment in calcium than in any other one chemical element." It seems surprising, in view of the study and ...
