The relationship of 1,25-dihydroxyvitamin D and radial bone mass [PDF]

Bone and Mineral, 1990
We assessed the association between radial bone mass and vitamin D considering age, estrogen sufficiency and thiazide use in 373 women, aged 20-80 years in a geographically defined area. We measured cortical bone mass of the radius, using photon absorptiometry, and serum 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D, using preliminary chromatography ...

Serum 1,25-dihydroxyvitamin D: an outcome prognosticator in human sepsis. [PDF]

PLoS ONE, 2013
In sepsis, the vitamin D active metabolite 1,25-dihydroxyvitamin D (1,25(OH)2D) may play a crucial role by its action to produce cathelicidin and improve endothelial barrier function, such that a deficiency in 1,25(OH)2D is associated with poor outcome ...

Skeletal unloading decreases production of 1,25-dihydroxyvitamin D

American Journal of Physiology-Endocrinology and Metabolism, 1993
The plasma concentration of 1,25-dihydroxyvitamin D [1,25(OH)2D] decreases during skeletal unloading and increases when normal weight bearing is restored. To determine whether these changes in plasma 1,25(OH)2D reflect changes in production, metabolic clearance, or both we measured the kinetics of 1,25(OH)2D metabolism in rats whose skeletons were ...

Evaluation of a 1,25-Dihydroxyvitamin D Enzyme Immunoassay [PDF]

Clinical Chemistry, 2007
AbstractBackground: Radioactive reagents are used in most assays for measurement of 1,25-dihydroxyvitamin D [1,25(OH)2D]. We evaluated a 1,25(OH)2D enzyme immunoassay (EIA) from IDS Ltd. that uses solid-phase immunoextraction and colorimetric detection and compared results to those of the thymus radioreceptor assay (RRA) for 1,25(OH)2D.Methods: We ...

Effects of Single Vitamin D Injection (200,000 Units) on Serum Fibroblast Growth Factor 23 and Sclerostin Levels in Subjects with Vitamin D Deficiency [PDF]

Endocrinology and Metabolism, 2017
BackgroundVitamin D deficiency remains common in all age groups and affects skeletal and non-skeletal health. Fibroblast growth factor 23 is a bone-derived hormone that regulates phosphate and 1,25-dihydroxyvitamin D homeostasis as a counter regulatory ...

The future of vitamin D analogs

Frontiers in Physiology, 2014
The active form of vitamin D3, 1,25-dihydroxyvitamin D3, is a major regulator of bone and calcium homeostasis. In addition, this hormone also inhibits the proliferation and stimulates the differentiation of normal as well as malignant cells ...
