  1. 1. Turnover of chylomicrons in the rat

    Författare :Magnus Hultin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mechanisms involved in the clearance of chylomicrons and aspects of the interactions at the vascular endothelium were studied in the rat.The poly-anion heparin, known to release lipoprotein lipase (LPL) from the vascular endothelium, enhanced the clearance of chylomicrons.

  3. 2. Triglyceride-rich lipoproteins : postprandial metabolism and composition in relation to atherosclerosis

    Författare :Johan Björkegren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :triglyceride-rich lipoproteins; very low density lipoproteins; chylomicrons; lipoprotein remnants; apolipoprotein E and C; cholesterol; atherosclerosis;

    Sammanfattning : A relationship between postprandial lipaemia and coronary heart disease (CHD) was established as early as the 1950s. Since then, most attention has been paid to postprandial triglyceride-rich lipoproteins (TRLs) of intestinal origin, i.e. chylomicrons and chylomicron remnants, whereas TRLs of hepatic origin, i.

  4. 3. 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

  5. 4. Pharmacometric Characterization of Postprandial Responses and Taste Perception in Individuals with Obesity

    Författare :Jennifer Leohr; Maria Kjellsson; Andrew Hooker; Martin Adiels; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; mechanism-based; categorical modeling; obesity; triglycerides; glucose homeostasis; taste perception; linked categorical;

    Sammanfattning : Obesity is a major health epidemic worldwide and occurs when long-term excess of energy intake beyond energy utilization leads to an increase in adipose tissue. Energy balance is coordinated by the central nervous system regulation of appetite and adaptive thermogenesis via a complex array of neuropeptides which communicate to the periphery by various circulating measures dictating the utilization of various energy sources such as, carbohydrates, fat, or protein.

  7. 5. Studies on the assembly and secretion of apolipoprotein B containing lipoproteins

    Författare :Karin Lindberg; Göteborgs universitet; []
    Nyckelord :apolipoprotein B; lipoprotein; lipoprotein biosynthesis; Brefeldin A; microsomal triglyceride transfer protein; liver fatty acid binding protein;

    Sammanfattning : Lipoproteins are water-soluble particles of lipids and proteins, which deliver water-insoluble lipids from intestine or liver to target tissues where the lipids are used as fuel or storage. Lipoproteins consist of a core of hydrophobic lipids surrounded by an amphipatic monolayer of polar lipids and specific proteins, apolipoproteins. LÄS MER
