  1. 21. Alterations in peripheral glucocorticoid metabolism : effects of weight changes

    Författare :Kotryna Simonyté; Cecilia Mattsson; Bo Angelin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11ß Hydroxysteroid dehydrogenase 1; obesity; glucocorticoids; cortisol; phosphoenolpyruvate carboxykinase; adipose tissue; liver; Endocrinology; Endokrinologi; medicin; Medicine;

    Sammanfattning : Background: An important role has been suggested for tissue-specific glucocorticoid metabolism in the development of obesity and its complications. 11ß hydroxysteroid dehydrogenase 1 (11ßHSD1) is an enzyme that catalyzes the interconversion of biologically inactive cortisone to active cortisol, thereby regulating its access to glucocorticoid receptors in target tissues.

  3. 22. Studies on alcoholic liver disease

    Författare :Knut Stokkeland; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :alcohol cirrhosis; cytochromes; autoantibodies; mortality; morbidity; prognosis; epidemiology; esophageal varices; lifetime drinking; lifetime alcohol intake;

    Sammanfattning : The overall aim of this thesis was to explore the impact of alcoholic cirrhosis in Sweden, and the relation between drinking patterns and beverage types and alcoholic cirrhosis, and to evaluate the possible role of autoantibodies in the pathogenesis of alcohol related liver disease. We found that rats had appearance of IgG against rat CYP3A 1 and CYP2E 1 during chronic ethanol feeding We found that patients had reactivity against CYP3A4 and CYP2E I in about 20 to 30% and 10 to 20% of the alcoholic sera.

  4. 23. Receptors for growth hormone and prolactin. Regulation and activation

    Författare :Gunnel Hellgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; GH receptor; Janus kinase; GH sensitivity; 5 -untranslated region; prolactin; prolactin receptor adipose tissue; liver; skeletal muscle; epidermal growth factor receptor; tyrosine kinase; kinase activity;

    Sammanfattning : Cytokine receptor activation is dependent on ligand-induced receptor dimerization or oligomerization and subsequent activation of several intracellular proteins. Activation of Janus kinases (Jaks) is probably the first intracellular event that occurs after receptor dimerization. LÄS MER

  5. 24. Non-Alcoholic Fatty Liver Disease : Aspects on Diagnosis and Long-term Prognosis

    Författare :Patrik Nasr; Stergios Kechagias; Mattias Ekstedt; Peter Lundberg; Einar Stefán Björnsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease affecting approximately 25% of the global population and is commonly recognized as the hepatic manifestation of the metabolic syndrome. The histological spectrum of NAFLD ranges from isolated steatosis to non-alcoholic steatohepatitis (NASH), with risk of developing fibrosis and subsequent cirrhosis and hepatocellular carcinoma.

  7. 25. The role of PPARalpha and growth hormone in hepatic lipid metaboism and atherosclerosis

    Författare :Anna Ljungberg; Göteborgs universitet; []
    Nyckelord :growth hormone; PPARalpha; atherosclerosis; lipid metabolism; fatty acids; apoB; ; ADRP; triglycerides; PGC-1; liver;

    Sammanfattning : Dyslipidemia mainly results from oversecretion of apoB-containing lipoproteins from theliver and is one of the most important risk factors for the development of atherosclerosis.Growth hormone (GH) plays a key role in the regulation of lipoprotein metabolism and thus,disturbances in GH secretion are associated with dyslipidemia and cardiovascular disease.
