Current Concepts of the Physiology and Biochemistry of Calcification
Clinical Orthopaedics and Related Research, 1981The current picture of the process of biological calcifications portrays the cells within the calcifying tissues as central factors controlling the deposition of mineral crystals in the extracellular matrix. The cell responds to hormones and second messengers, and other changes in its environment, regulating the concentration of ions within the ...

The Biochemistry and Physiology of Bone, vol 4: Calcification and Physiology
JAMA: The Journal of the American Medical Association, 1977The latest volume in this excellent series fulfills a stated desire of the editor to produce a relatively complete treatise on bone. Although not originally planned, volume 4 became an obvious necessity to cover several important topics omitted from preceding issues.

Physiological and Radiological Implications of a Low Incidence of Pineal Calcification in Nigeria
Neuroendocrinology, 1972In a retrospective study of 952 skull X-rays taken in a few Lagos hospitals, it was found that the over-all incidence of calcification of the pineal gland was surprisingly low: 5.04% compared with ...

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2003
Emiliania huxleyi and Gephyrocapsa oceanica are the predominant coccolithophorid species that produce blooms in the ocean and affect the global environment. These species are capable of carbon fixation by both photosynthesis for organic matter production and by intracellular calcification for coccolith production.

Physiological variables involved in heart valve substitute calcification
Expert Opinion on Biological Therapy, 2009Biochemical, histological and genetic studies using in vitro/in vivo models have demonstrated that pathological calcification of bioprosthetic heart valves (BHV) is regulated by various mechanisms associated with physiological variables. The major objective of this review is to characterize physiological variables involved in BHV calcification.

Basal Ganglia: Physiologic Calcifications
2017Basal ganglia (BG) calcifications are a common cause of either confusion or misinterpretation, particularly when the degree of calcification is only mild or unilateral. In general, although there is no landmark recent literature regarding the incidence of idiopathic, incidence BG calcifications on CT, the incidence is thought to be less than 2 % in the

An improved 45Ca protocol for investigating physiological mechanisms in coral calcification
Marine Biology, 1995A sensitive experimental protocol using cloned corals (hereafter “microcolonies”) of the branching scleractinian coral Stylophora pistillata and 45Ca has been developed to enable reproducible measurements of physiological and biochemical mechanisms involved in calcium transport and compartmentalization during coral calcification. Cloned S.

ABSTRACT The union of calcium cations with carbonate anions to form calcium carbonate (CaCO3) is a fundamentally important physiological process of many marine invertebrates, in particular the corals. In an effort to understand the sources and processes of carbon uptake and subsequent deposition as calcium carbonate, a series of studies ...

[Impact on calcification of aortic arch by lifestyle-related, physiologic and biochemical factors].
Zhonghua liu xing bing xue za zhi = Zhonghua liuxingbingxue zazhi, 2009To explore the impact of lifestyle-related, physiological and biochemical factors on aortic arch calcification (AAC).20 430 subjects aged 50 to 85 years were included in this study from the first and second recruitment phase of the Guangzhou Biobank Cohort Study. All the subjects received face-to-face interviews to collect detailed information on their
