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.

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 ...

Vitamin D and Calcium and Bioavailability of Calcium in Various Calcium Salts
Indian Journal of Orthopaedics, 2023The active form of vitamin D, 1,25D3, plays an important function in the metabolism of calcium. The recommended daily INTAKE of Calcium varies from 1300 mg/day during adolescence to 1200 mg/day after the age of 50 years. Similarly, for vitamin D, the recommended daily intake varies from 400 IU/day during adolescence to 1000 IU/day after the age of 70 ...

The Journal of Nutrition, 1986
It seems we are about back to square one and the question that still needs an answer is whether diet, or calcium intake, plays a really significant role in the etiology of osteoporosis, especially hip fractures. Logic may tell us that calcium intake ought to be important but the evidence is weak.

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.

Journal of Molecular and Cellular Cardiology, 1986
In contrast to nifedipine-like calcium antagonists, calcium agonistic 1,4-dihydropyridines have vasoconstricting and positive inotropic properties. BAY K 8644 has become the prototype of this new class. Its enantiomers show opposite effects on the calcium channel: one acts as a calcium agonist with the pharmacological profile of the racemic compound ...

This chapter describes the chemical and biological value of the calcium ion. In calcium chemistry, our main interest is in equilibria within static, nonflowing systems. Hence, we examined the way calcium formed precipitates and complex ions in solution.
