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 ...

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.

The Effect of Treatment of Acidosis on Calcium Balance in Patients with Chronic Azotemic Renal Disease [PDF]
, 1967 Small but statistically significant negative calcium balances were found in each of eight studies in seven patients with chronic azotemic renal disease when stable metabolic acidosis was present.

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 ...

Preparation and characterization of new hybrid organic/inorganic systems derived from calcium (aminoalkyl)-phosphonates and -phosphonocarboxylates [PDF]
, 2005 We have studied the phenomenon of calcium complexation by lab synthesized amphiphilic (α-aminoalkyl)-phosphonocarboxylic or -phosphonic acids. The electrical conductivity of aqueous solutions of sodium salts of all these acids was measured versus the ...

Relative Bioavailability of Calcium from Calcium Formate, Calcium Citrate, and Calcium Carbonate [PDF]
The Journal of Pharmacology and Experimental Therapeutics, 2005 Calcium is an essential nutrient required in substantial amounts, but many diets are deficient in calcium making supplementation necessary or desirable. The objective of this study was to compare the oral bioavailability of calcium from calcium formate, a new experimental dietary calcium supplement, to that of calcium citrate and calcium carbonate.

HSPB7 oppositely regulates human mesenchymal stromal cell-derived osteogenesis and adipogenesis
Stem Cell Research & Therapy, 2023 Background Recent evidence suggests that accumulation of marrow adipose tissue induced by aberrant lineage allocation of bone marrow-derived mesenchymal stromal cells (BMSCs) contributes to the pathophysiologic processes of osteoporosis.

Calcium Carbonate Suppresses Haem Toxicity Markers without Calcium Phosphate Side Effect on Colon Carcinogenesis [PDF]
, 2010 Red meat intake is associated with increased risk of colorectal cancer. We have previously shown that haemin, haemoglobin and red meat promote carcinogen-induced preneoplastic lesions, aberrant crypt foci, in the colon of rats.
