BACKGROUND Oxysterols are oxidized forms of cholesterol. They have been shown to be implicated in cholesterol turnover, inflammation and in neurodegenerative diseases such as Alzheimer's disease and multiple sclerosis. Glial cells are targets of oxysterols: they inhibit astrocyte proliferation after brain injury, and we have previously shown that 25-hydroxycholesterol (25OH) provokes oligodendr...

Idiopathic hypercalciuria is a risk factor for nephrolithiasis. Both renal stones and hypercalciuria are associated with ...

It has been suggested that vitamin D contributes not only to bone mineral metabolism but also to important other physiological processes. Vitamin D levels have been associated with increased mortality in predialysis and incident HD patients, but no data is available on the association between vitamin D levels and survival in prevalant hemodialysis (HD) patients. Five hundred and forty five prev...

BACKGROUND Essential nutrients are considered for the prevention of the bone loss that occurs after bariatric surgery. AIM Evaluate nutrients involved in bone metabolism, and relate to serum concentrations of calcium, vitamin D, and parathyroid hormone, and the use of supplements and sun exposure on the bone mass of patients who had undergone gastric bypass surgery. METHODS An observational...

Vitamin D deficiency is associated with a number of human disorders, including cardiovascular disease, cancer, diabetes, frailty, and infections. Since an association between vitamin D and migraine has also been recently speculated, we performed an electronic search on Medline, Scopus, and Web of Science using the keywords "migraine" and "vitamin D," "25OH-D" "cholecalciferol," "ergocalciferol,...

An in vitro assay of mammalian 25-hydroxyvitamin D3 laand 24R-hydroxylases in kidney has been developed. It had been suggested that 25-hydroxyvitamin D binding protein present in mammalian blood and tissues inhibits the enzyme activities in cell-free preparations by binding the substrate 25-hydroxyvitamin D3 more strongly than the hydroxylases bind it. This inhibitory effect is overcome by the ...

Objective: Psoriasis is an inflammatory disease of the skin and the joints. Psoriatic patients sometimes suffer from vitamin D deficiency and hypocalcemia. The aim of our study was to evaluate the level of calcium and vitamin D in patients with psoriasis. Materials and Methods: In this analytical cross sectional study, 110 cases of psoriasis that were referred to Shohadaye Mehrab clinic during...

Various studies have demonstrated that increased leptin levels and obesity are inversely related to cognitive decline in menopausal women. It is hypothesized that adiposity is inversely correlated with cognitive decline, as women with increased weight are less vulnerable to diminishing cognition. However, it is increasingly observed that menopausal women, even with increased adiposity, experien...
