multiple sclerosis (ms) is a chronic demyelinating disease and also is one of the most common disabling neurological disorders in young and middle-aged adults. the main pathogenesis of ms has long been thought to be an immune mediated disorder of the central nervous system. the function of the immune system is under the influence of vitamin d which as a modulator of immune response could play a...

background: vitamin d plays a critical role in the regulation of growth and differentiation of squamous epithelium. the pleiotropic effects of 1,25-dihydroxyvitamin d3 [1,25(oh)2d3], include proliferative, pro-apoptotic, and pro-differentiation effects on numerous cell types. although 1,25-dihydroxyvitamin d3 is involved in the regulation and differentiation of epithelium, there is no data in t...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

multiple sclerosis (ms) is a multifactorial disease (caused by both environmental and genetic features) that could results from a demyelination of the myelin sheath. subsequently, it leads to many scars or lesions in different places within the central nervous system. the symptoms that occur depend on the site and rigorousness of the lesions and this is why people with ms experience different s...

b a ckground:  the purpose of our study was to investigate the possible effect of  bsm i vitamin d receptor (vdr’s) polymorphism on changes of the inflammatory and oxidative stress (os) biomarkers in response to daily intake of vitamin d- fortified yogurt drink ( doogh ) in subjects with type 2 diabetes (t2d). m ethods : in a randomized controlled trial, 100 t2d subjects were allocated to two g...

There are many immune mediated disorders with the corroborated role of vitamin D or Vitamin D Receptor (VDR) gene polymorphisms in their pathogenesis, immunologic regulation, and disease characteristics. Therefore, in this review, we searched PubMed data base in regard to the role of VDR gene polymorphisms in common autoimmune disorders, emphasizing on dermatologic diseases.

background: osteoporosis, or porous bone, is a disease characterized by low bone mass density (bmd) and structural deterioration of bone tissue, leading to bone fragility and increased risk of hip, spine, and wrist fractures. there are numerous risk factors for osteoporosis. while many of these factors are non-genetic in nature, there is a definite genetic component responsible for this conditi...

Background: Vitamin D has been well-known for its function in maintaining calcium and phosphorus homeostasis and promoting bone mineralization. There is some evidence that in addition to sex steroid hormones, the classic regulators of human reproduction, vitamin D also modulates reproductive processes in women and men. Materials and Methods: This is a review article that were identifical by com...
