Advances in Nutrition, 2011 Calcium is the fifth most abundant element in the body with >99% residing in the skeleton as hydroxyapatite, a complex calcium phosphate molecule. This mineral supplies the strength to bones that support locomotion, but it also serves as a reservoir to maintain serum calcium concentrations.

Calcium-induced calcium release [PDF]
Current Biology, 2003 Why is calcium so important? Intracellular calcium controls a diverse array of cellular processes from fertilisation through gene transcription, muscle contraction to cell death. Changes in calcium levels can occur in microseconds or hours, they can be microscopic or propagate throughout cells and tissues.How are calcium levels increased within cells ...

Kidney International, 2000 Calcium is an important intracellular signaling molecule, and altered calcium channel function can cause widespread cellular changes. Genetic mutations in calcium channels that cause what appear to be trivial alterations of calcium currents in vitro can result in serious diseases in muscles and the nervous system.

Water calcium concentration modifies whole-body calcium uptake in sea bream larvae during short-term adaptation to altered salinities [PDF]
, 2014 Whole-body calcium uptake was studied in gilthead sea bream larvae (9–83·mg) in response to changing environmental salinity and [Ca2+]. Calcium uptake increased with increased fish size and salinity.

Genes and Diseases, 2022 Proximal tubule (PT) transports most of the renal Ca2+, which was usually described as paracellular (passive). We found a regulated Ca2+ entry pathway in PT cells via the apical transient receptor potential canonical 3 (TRPC3) channel, which initiates ...

Pseudohypocalcemia caused by perchlorate (Irenat (R)) [PDF]
, 2011 Background: Blood gas analysis (BGA), including measurement of ionized calcium, is performed routinely in patients with end stage renal disease on renal replacement therapy, especially when using citrate for regional anticoagulation.
