  1. 1. Liver regeneration : With reference to malnutrition and growth factors

    Författare :Stefan Skullman; Linköpings universitet; []
    Nyckelord :cholecystokinin; energy substrates; epidermal growth factor; insulin-like growth factor I; liver composition; liver regeneration; malnutrition; pancreaticobiliary diversion; protein synthesis; rat; transfonning growth factor alpha; MEDICINE; MEDICIN;

    Sammanfattning : The liver has a unique capacity to regenerate after damage, irrespective of cause. The regulatory mechanisms of this regeneration are not fully known. Liver regeneration· is associated with rapid growth and thereby increased demands for energy and synthesis of new compounds. LÄS MER

  2. 2. Effects of GH and liver-derived IGF-I on growth and metabolism

    Författare :Klara Sjögren; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GH; IGF-I; Insulin; GHRH; Somatostatin; GHS; Body growth; Body composition; Liver; Bone mineral content; Bone mineral density.;

    Sammanfattning : Growth hormone (GH) exerts major effects on body growth and metabolism. Insulin-like growth factor (IGF) is expressed in response to GH and is known to mediate many of the effects of GH. The largest expression of IGF is found in the liver although it is expressed in virtually every tissue of the body. LÄS MER

  3. 3. Dietary Fatty Acids, Body Composition and Ectopic Fat : Results from Overfeeding Studies in Humans

    Författare :Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Linoleic acid; Palmitic acid; SFA; PUFA; Fatty acids; Body composition; Liver fat; Ectopic fat; Adipose tissue; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The aim of this thesis was to investigate the effects of dietary fatty acids on body composition and ectopic fat in humans, with emphasis on the role of the omega-6 polyunsaturated fatty acid (PUFA) linoleic acid (18:2n-6) and the saturated fatty acid (SFA) palmitic acid (16:0). The overall hypothesis was that linoleic acid would be beneficial compared with palmitic acid during overfeeding, as previously indicated in animals. LÄS MER

  4. 4. Computed Tomography and Magnetic Resonance Imaging in Determination of Human Body Composition. Methodological and Applied Studies

    Författare :John Brandberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :X-ray Computed Tomography; Magnetic Resonance Imaging; Body Composition; Obesity; Metabolic Syndrome X; Glucose Metabolism; Growth Hormone; Fatty Liver; Intra-Abdominal Fat;

    Sammanfattning : Background: Computed tomography (CT) and magnetic resonance imaging (MRI) provide important research opportunities due to their unique capability of characterizing and quantifying tissues and organs. Ionizing radiation is a limitation using CT, and recent developments aiming to improve MRI for determination of body composition have not been validated. LÄS MER

  5. 5. Intestinal Gene Expression Profiling and Fatty Acid Responses to a High-fat Diet

    Författare :Jonathan Cedernaes; Helgi B Schiöth; Robert Fredriksson; Anders Jacobsson; Uppsala universitet; []

    Sammanfattning : The gastrointestinal tract (GIT) regulates nutrient uptake, secretes hormones and has a crucial gut flora and enteric nervous system. Of relevance for these functions are the G protein-coupled receptors (GPCRs) and the solute carriers (SLCs). LÄS MER
