    Abstract : Vitamin D has received much attention in recent years due to the re-emergence of vitamin D deficiency as a global health issue along with increasing evidence indicating that 1,25-dihydroxivitamin D, the hormonally active form of vita-min D, not only acts in calcium and bone metabolism but also generates ex-traskeletal biological responses.In this thesis, the role of vitamin D in obesity and other associated condi-tions has been studied.

  3. 13. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Author : Johan Lundqvist; Kjell Wikvall; Maria Norlin; Magnus Ingelman-Sundberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal steroidogenesis; CYP7B1; vitamin D; calcitriol; enzymatic regulation; transcriptional regulation; CYP21A2; aromatase; sex hormone; estrogen; androgen; nuclear receptor; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

  4. 14. 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

  5. 15. Vitamin D In Older Women - Fractures, Frailty and Mortality

    Author : David Buchebner; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Keywords : Vitamin D; Women; Fracture; Frailty; Mortality;

    Abstract : Vitamin D (25OHD) is essential for maintaining calcium homeostasis and inadequate levels have been associated with negative musculoskeletal as well as extraskeletal effects. Individuals at especially high risk of developing hypovitaminosis D are the elderly. READ MORE
