Modification of the zirconia ceramics by different calcium phosphate coatings:comparative study [PDF]

, 2017
The aim of this study was to characterize different calcium phosphate coatings and evaluate in vitro cell response of these materials to ceramics implants. The physical and chemical properties of calcium phosphate coatings formed by RF-magnetron sputtering of calcium phosphate tribasic, hydroxyapatite, calcium phosphate monobasic, calcium phosphate ...

Calcium-rich Gap Transients: Solving the Calcium Conundrum in the Intracluster Medium [PDF]

, 2014
X-ray measurements suggest the abundance of Calcium in the intracluster medium is higher than can be explained using favored models for core-collapse and Type Ia supernovae alone. We investigate whether the Calcium conundrum in the intracluster medium can be alleviated by including a contribution from the recently discovered subclass of supernovae ...

The volumetric rate of calcium-rich transients in the local universe [PDF]

, 2018
We present a measurement of the volumetric rate of `calcium-rich' optical transients in the local universe, using a sample of three events from the Palomar Transient Factory (PTF). This measurement builds on a detailed study of the PTF transient detection efficiencies, and uses a Monte Carlo simulation of the PTF survey.

Calcium [PDF]

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 ...

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.

The 2011 Report on Dietary Reference Intakes for Calcium and Vitamin D from the Institute of Medicine: What Clinicians Need to Know

Journal of Clinical Endocrinology and Metabolism, 2010
This article summarizes the new 2011 report on dietary requirements for calcium and vitamin D from the Institute of Medicine (IOM). An IOM Committee charged with determining the population needs for these nutrients in North America conducted a ...

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.
