  1. 16. Early steps of Eicosanoid precursor absorption and tissue distribution

    Författare :Tor Melin; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipids; mebran; steroider; Lipider; steroids; membranes; Gastro-enterology; Gastroenterologi;

    Sammanfattning : Eicosanoids are important for a wide range of physiological and pathophysiological processes.How their essential fatty acid precursors are absorbed and tissue distributed is not well charactherized. When given orally to rats, arachidonic acid (20:4) was retained in the small intestine to a larger extent than linoleic acid (18:2). LÄS MER

  3. 17. Obesity and Increased Susceptibility : Role of FTO and MGAT1 Genetic Variants

    Författare :Josefin A Jacobsson; Robert Fredriksson; Helgi B Schiöth; Sadaf Farooqi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; BMI; SNP; haplotype; association study; FTO; MGAT1; Pharmacology; Farmakologi; Farmakologi; Pharmacology;

    Sammanfattning : Obesity is a complex and a highly individualized disease and the molecular mechanisms behind this disorder need to be better elucidated. Identification of genes and genetic variants that are involved provide opportunities to establish a genetic understanding of the disease. LÄS MER

  4. 18. Palmitate-induced Apoptosis in Insulin-producing β-cells

    Författare :Kristofer Thörn; Peter Bergsten; Claes Wollheim; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ER stress; apoptosis; palmitate; sphingosine-1-phosphate; ceramide; beta-cell; fatty acid; Medical cell biology; Medicinsk cellbiologi; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Type 2 diabetes is a disease characterized by the inability of pancreatic β-cells to secrete sufficient amounts of insulin to maintain normoglycemia. Increased levels of saturated fatty acids such as palmitate are believed to contribute to β-cell failure and the development of the disease. LÄS MER

  5. 19. Influence of oilseed supplementation on ruminant meat and milk with emphasis on fatty acids

    Författare :Tyler Turner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In the human diet, long-chain polyunsaturated fatty acids (LC-PUFA, ≥ C20) are supplied almost exclusively from animal sources. Red meat represents a significant source of LC-PUFA in many areas of the world. However, the health aspects of consuming ruminant tissues are often viewed critically due to the proportions of saturated fatty acids (SFA). LÄS MER

  7. 20. Growth hormone and PPARalpha in the regulation of genes involved in hepatic lipid metabolism

    Författare :Caroline Améen; Göteborgs universitet; []
    Nyckelord :Growth hormone; insulin; SREBP-1; lipogenic enzymes; microsomal triglyceride transfer protein; PPARalpha; LXRalpha; triglycerides; liver;

    Sammanfattning : Growth hormone (GH) plays a key role in the regulation of lipid and lipoprotein metabolism. Its sexually dimorphic secretory pattern regulates many sex-differentiated functions in the liver, such as triglyceride synthesis and VLDL secretion. LÄS MER
