2. 1. Aspects of Vitamin D : Prevalence of deficiency and impact on musculoskeletal parameters

   Author : Anne Björk; Östen Ljunggren; Gunnar Johansson; Andreas Kindmark; Anna Spångeus; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; CYP2R1; Vitamin D receptor Gene; Polymorphisms; Muscle Strength; Endokrinologi och Diabetologi; Endocrinology and Diabetology;

   Abstract : Vitamin D is central in calcium turnover, and adequate levels are important for skeletal health. It is not clear how large contributions from food and sunlight are in Swedish primary care patients, considering the low radiation of UVB in Sweden and fortification of some foods, and whether differences exist between patients of immigrant and Swedish origin.

4. 2. Vitamin A and Osteoporosis : Experimental and Clinical Studies

   Author : Sara Johansson; Håkan Melhus; Andreas Kindmark; Monica Lind; Göran Toss; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; vitamin A; bone; osteoporosis; Invärtesmedicin; Internal medicine; Invärtesmedicin;

   Abstract : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. READ MORE

5. 3. Vitamin D Hydroxylating Enzymes and Analogues in Parathyroid Tumors and Breast Cancer

   Author : Ulrika Segersten; Gunnar Westin; Per Hellman; Göran Åkerström; Martin Bäckdahl; Uppsala universitet; []

   Abstract : In hyperparathyroidism (HPT) raised serum concentrations of ionized calcium is caused by increased secretion of parathyroid hormone (PTH) by parathyroid tumors. Active vitamin D, 1α,25-dihydroxyvitamin D3, is known to suppress PTH secretion and to reduce proliferation of parathyroid tumor cells. READ MORE

6. 4. Calciumhomeostasis and Vitamin D in Obesity and Preeclampsia

   Author : Hella Hultin; Per Hellman; Ylva Pernow; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium homeostasis; vitamin D; preeclampsia; obesity; parathyroid hormone; Endocrine surgery; Endokrin kirurgi; Kirurgi; Surgery;

   Abstract : Normal physiological functioning is highly dependent of calcium and the concentration range is very narrow. Normal calcium levels are so crucial to survival that the body will de-mineralize bone if the levels are insufficient. A prerequisite for normal calcium uptake is a normal Vitamin D level. READ MORE

7. 5. Exploring vitamin D and steroid hormone receptors – from healthy elderly to prostate cancer cells
