Calcium binding to fluorescent calcium indicators: Calcium green, calcium orange and calcium crimson

Biochemical and Biophysical Research Communications, 1991
The 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 ...

Dietary Reference Intakes for Calcium and Vitamin D

Pediatric Clinical Practice Guidelines & Policies, 2016
Calcium and vitamin D are two essential nutrients long known for their role in bone health. Over the last ten years, the public has heard conflicting messages about other benefits of these nutrients—especially vitamin D—and also about how much calcium ...

Calcium entry in the calcium paradox

Journal of Molecular and Cellular Cardiology, 1981
Abstract 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

Store-operated calcium channels.

Physiological Reviews, 2005
In electrically nonexcitable cells, Ca(2+) influx is essential for regulating a host of kinetically distinct processes involving exocytosis, enzyme control, gene regulation, cell growth and proliferation, and apoptosis.

Calcium Requirement and Calcium Therapy

Clinical Orthopaedics and Related Research, 1979
The 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, ATP, and ROS: a mitochondrial love-hate triangle.

American Journal of Physiology - Cell Physiology, 2004
The mitochondrion is at the core of cellular energy metabolism, being the site of most ATP generation. Calcium is a key regulator of mitochondrial function and acts at several levels within the organelle to stimulate ATP synthesis.

Calcium, calcium channels, and calcium channel antagonists

Canadian Journal of Physiology and Pharmacology, 1990
Voltage-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 ...

Calcium

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.
