Background: The prevalence of diabetes mellitus due to existence of various factors is growing rapidly. The insulin resistance phenomenon is one of the main underlying causes of this disease, due to various reasons such as a decrease in serum levels of vitamin D3. In this study, we evaluated the relationship between plasma level of vitamin D3 and some other main plasma factors. Methods: This c...
An adequate vitamin D status is essential to optimize muscle strength. However, whether vitamin D directly reduces muscle fiber atrophy or stimulates muscle fiber hypertrophy remains subject of debate. A mechanism that may affect the role of vitamin D in the regulation of muscle fiber size is the local conversion of 25(OH)D to 1,25(OH)2 D by 1α-hydroxylase. Therefore, we investigated in a murin...
background: recent studies have shown the immunomodulatory effect of vitamin d3 through down-regulation of toll-like receptor (tlr) expression in human monocytes. in this study, the effects of vitamin d treatment on tlr2 and tlr4 expression on monocytes derived from type 2 diabetes was investigated. materials and methods: to assess the influence of vitamin d3 on expression of tlr2 and tlr4 on m...
The 25-hydroxyvitamin D3 (25-OH-D3) is a nontoxic and low-affinity vitamin D receptor (VDR)-binding metabolic precursor of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]. We hypothesized that covalent attachment of a 25-OH-D3 analog to the hormone-binding pocket of VDR might convert the latter into transcriptionally active holo-form, making 25-OH-D3 biologically active. Furthermore, it might be possibl...
This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0....
Background and Objective: Chronic use of antiepileptic drugs may influence the bones and their mineral metabolism due to deficiency of vitamin D3. In this study we investigated the effect of high dose vitamin D3 on bones and their mineral metabolism. Materials and Methods: Fifty six children older that 3 years old who were affected by epilepsy and had taken the antiepileptic drugs at least for ...
