results coincubation of islets with vitamin d (10 nm) and 11.1 mm glucose increased islet insulin release (37.27 ± 3.75 vs. 24.64 ± 2.83 ng/islet/24 hours; p < 0.05), while vitamin d (1 and 10 nm) decreased insulin release in the presence of 16.7 mm glucose (21.14 ± 3.58 and 18.65 ± 3.84 vs. 37.71 ± 4.63 ng/ islet/24 hours; p < 0.05). islets preincubation with vitamin d (1 and 10 nm) increased ...

Vitamin D deficiency has emerged as a significant public health problem throughout the world. Even in the Indian context,it has been reported to be present in majority of children in spite of wide availability of sunlight. Recent guidelines have defined vitamin D status as severe deficiency, deficiency, sufficiency and risk for toxicity as 25(OH)D levels <5, <15, >20 and >50ng/mL, respectively....

background: recent studies have demonstrated the high prevalence of vitamin d deficiency in the general population. pregnancy and preterm delivery are known as risk factors for vitamin d deficiency. consequently, vitamin d level in women with preterm deliveries might vary from those with term pregnancies. in this study, we aimed to compare vitamin d level in term and preterm infant–mother pairs...

low plasma level of vitamin d is linked to the increased risk of cardiovascular diseases such as hypertension, diabetes, dyslipidemia and peripheral vascular diseases. vitamin d deficiency is a worldwide problem that involves iranian population. to the best of our knowledge, this was the first investigation on venous thromboembolism (vte) subjects that assessed the correlation of vitamin d leve...

Background Vitamin D deficiency is associated with physiologic changes that are similar to pathogenesis of preeclampsia. Although association of vitamin D and preeclampsia has been studied previously, their results are not consistent. The aim of this study was to investigate the relationship of serum vitamin D and calcium with preeclampsia severity. Materials and Methods: This case- control st...

Background: Generalized vitiligo is characterized by autoimmunedestruction of melanocytes, which results in patches of thedepigmented skin and the overlying hair. Vitamin D is an essentialhormone synthesized in the skin and is responsible for skinpigmentation. Low vitamin D levels have been noted in patientswith a variety of autoimmune diseases. A recent study showedthat low vitamin D levels ma...

The aim of this study was to assess the correlation of serum vitamin D with ICU length of stay, mortality rate, length of mechanical ventilation, and incidence of sepsis. We conducted a descriptive analytic study on 793 patients admitted to surgical ICU wards in northwest of Iran from March 2015 to March 2016. Patients were assessed during the ICU stay and the following data were collect...

Objective: The current study was conducted to compare the effect of 150,000 and 300,000 IU of vitamin D on the healing status of diabetic foot ulcer among the patients with diabetes. Materials and Methods: This randomized clinical trial was carried out on 47 patients with diabetic foot ulcer and vitamin deficiency during four weeks follow-up. The patients were randomly assigned into two groups...
