Placental genetic variations in vitamin D metabolism and birthweight

Placental Calcification and Vitamin D Deficiency in Low-Risk Pregnant Women

Background: The placental calcification is often considered as a physiologic aging process of the placenta but it may be accompanied with the altered levels of vitamin D (vit D). The aim of this study was to evaluate association between placental calcification and vit D in low risk pregnant women.  Materials and Methods: In a case-contro...

Vitamin D and the Regulation of Placental

Calcium and Vitamin D Metabolism in Pediatric Nephrotic Syndrome; An Update on the Existing Literature

 Minimal Change Disease (MCD) is the leading cause of childhood Nephrotic Syndrome (NS). Therefore in pediatrics nephrotic syndrome, most children beyond the first year of life will be treated with corticosteroids without an initial biopsy. Children with NS often display a number of calcium homeostasis disturbances causing abnormal bone histology, including hypocalcemia, reduced serum vitamin D...

Parathyroid Hormone-Related Peptide and Vitamin D in Phosphocalcic Metabolism for Dromedary Camel

In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...

Vitamin D Metabolism and Physiology

Background. Vitamin D insufficiency may lead to various health problems. By encouraging sun protection to prevent skin cancer, physicians may be limiting a major source of vitamin D for many individuals. Methods. We did a literature review on issues related to vitamin D inadequacy, particularly those relevant to various racial/ethnic groups. Results. Vitamin D is an important hormone with many ...
