Background: Vitamin D is one of the known lipoprotein hormones with metabolic properties. We aimed to determine the serum 25-hydroxy vitamin D concentration in overweight/obese subjects with diabetes mellitus type Ⅱ (DM Ⅱ) in association with systolic and diastolic blood pressure and quality of life compared with healthy participants. Methods: The current case-control study was carried out amo...

Background and Objectives: Day-shift taxi drivers have a long duration of direct sun exposure. However, the efficiency of this occupational exposure in vitamin D synthesis has not been addressed yet. The aim of this study was to assess the vitamin D status of taxi drivers in Tehran, and examine vitamin D status association with some anthropometric and circulating biomarkers. Materials and Meth...

Precocious puberty can cause several adverse effects on final growth and social behavior in girls. Recently studies showed that low serum vitamin D levels might be associated with precocious puberty. The aim of  this research was to investigate the association between serum vitamin D levels and central precocious puberty in girls. Girls with central precocious puberty under the age of 8 we...

  Background : There is no data available regarding vitamin D status among patients with hip fractures in Iran. This study aimed to determine whether postmenopausal women with low trauma hip fractures have lower vitamin D levels comparing to the control group.   Materials and Methods: Vitamin D (25-OHD) level and the prevalence of hypovitaminosis D among 73 postmenopausal women wit...

various sources of geodetic, geological and geophysical information can improve our understanding about the crustal density. in this paper we propose a methodology for determination of crustal density based on terrestrial gravity observations, geopotential models, digital terrain models (dtm), geological maps and cross-sections, deep geophysical profiles, and geoid models. the method can be alg...

  Background: The main purpose of this study was to determine the relationship between serum vitamin D and the status of bone mineral density in patients with low-energy hip and distal radius fracture. Methods: This retrospective case-control study was performed between January 2013 and January 2014. Participants aged 55 years or older were divided to case group including 85 patients with lo...

Background: The effects of vitamin D in skeletal system, biological metabolism and immune system function are well shown. Cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are two major types of vitamin D. Vitamin D deficiency is widely in human population and vitamin D intoxication is very rare. Case Description: The patient is 37-years old bodybuilder man who referred to emergency...
