   Sammanfattning : Risk factors for dementia, Parkinson’s disease, and stroke have been widely studied but there are still research gaps concerning the role of diet for the development of these diseases. The overall aim of this thesis was to investigate whether various aspects of diet are associated with common disorders and diseases in the brain. LÄS MER

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

   Författare :Ulrika Segersten; Gunnar Westin; Per Hellman; Göran Åkerström; Martin Bäckdahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; hyperparathyroidism; breast cancer; vitamin D; CYP27B1; CYP24A1; vitamin D analogues; ketoconazole; vitamin D receptor; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : 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. LÄS MER

5. 4. Studies on 4b-hydroxycholesterol, a marker of CYP3A activity, and its association with 25-hydroxyvitamin D

   Författare :Hanna Nylén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cholesterol is a vital compound that can undergo cytochrome P450 (CYP) mediated conversion into steroid hormones, bile acids and oxysterols. CYP enzymes are present in all human tissues and mediate the metabolism of several endogenous and exogenous compounds such as steroids and drugs. LÄS MER
