Part of these publications deal with the definition of what is a "normal" circulating level of 25(OH) D that may distinguish between health and disease. The literature also deals with seasonal variations of vitamin D, showing levels that rise in summer and fall in winter and with \\\{DBP...
The aim of the study was to examine possible variations in the levels of 25-hydroxy vitamin D [25-(OH)D] in sera from normal Biozzi and C57BL/6 mice and during the course of chronic relapsing experimental autoimmune encephalomyelitis (CR EAE).Serum concentrations of 25-(OH)D were measured...
Fig. 2. 1,25-Dihydroxyvitamin D serum levels. A, Mean 1,25-(OH)2D values over 6 years for each patient with XP. Values were in normal range for all. Group mean (mean of the means) represent- ed as final bold symbol. B, Multiple 1,25-(OH)zD values over 6 years for each ...
Vitamin D is produced in the skin upon exposure to ultraviolet light (sunlight). It is activated in two steps to function as a key regulator of mineral ion homeostasis. Vitamin D becomes bound to the vitamin D binding protein, DBP, in the circulation and
These patients had Vitamin D levels comparable to those in the general population in Denmark. Therefore, our hypothesis was not supported. Firstly, low levels of Vitamin D were not related to the clinical symptoms. Secondly, Modic changes were less common in people with low levels of Vitamin D...
New research indicates that for patients with advanced skin cancer, it may be important to maintain normal vitamin D levels when receiving immunotherapy medications called immune checkpoint inhibitors. The findings are published by Wiley online in CANCER
Using a specific vitamin D metabolite assay, the serum levels of various metabolites were measured in 3 children with a history of decreased dietary intake of vitamin D and sun exposure; two had rickets, aminoaciduria and elevated iPTH levels. In some osteomalacic adults, calcitriol levels are ...
We measured the free concentration of 1,25-dihydroxyvitamin D (1,25[OH]2D) using centrifugal ultrafiltration, and the level of vitamin D-binding protein (DBP) in 24 normal subjects, 17 pregnant subjects, and 25 alcoholic subjects with liver disease. Our objective was to determine whether the ...
