  1. 1. Gastric Bypass in Morbid Obesity : Postoperative Changes in Metabolic, Inflammatory and Gut Regulatory Peptides

    Författare :Camilla Holdstock; Britt Edén Engström; Anders Karlsson; Per Hellström; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; gastric bypass; morbid obesity; ghrelin; C-reactive protein; pancreatic polypeptide; peptide YY; glucagon-like peptide-1; Medicine; Medicin;

    Sammanfattning : This thesis examines the effect of surgical weight loss on gut and adipose tissue peptides involved in appetite regulation and energy homeostasis in morbidly obese humans. Roux-en-Y gastric bypass (RYGBP) is the gold standard operation used for effective long-term weight loss and improved health. LÄS MER

  3. 2. Evolution and Pharmacology of Neuropeptide Y Receptors, Implications for vertebrate genome duplications

    Författare :Robert Fredriksson; Susanne Holmgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Evolution; tetraploidizations; G-protein coupled receptor; neuropeptide Y; zebrafish; chicken; rainbow trout; lamprey; genome duplications; peptide YY; pancreatic polypeptide; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : The Y receptors comprise a family of evolutionarily related receptors belonging to the superfamily of G-protein coupled receptors (GPCR). Their natural ligands are in mammals neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER

  4. 3. The small bowel and functional dyspepsia : peptide hormones and neurotransmitters

    Författare :Anne-Barbara Witte; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Functional dyspepsia (FD) is believed to be caused by pathophysiological changes in the upper gut. Gastro-intestinal motility, epithelial transport and signalling is associated with the metabolism of nutrients and the complex regulation of hunger and satiety. Glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) are considered “hot targets”. LÄS MER

  5. 4. Stress-related peptides in suicide attempters

    Författare :Åsa Westrin; Lund Psykiatri; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; temperament; cortisol; neuropeptide Y; delta sleep-inducing peptide; somatostatin; beta-endorphin; corticotropin-releasing hormone; hypothalamic pituitary adrenal axis; attempted suicide; affective disorders; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Sammanfattning : A suicide attempt is the best known predictor of completed suicide. It has long been assumed that most suicide attempts are the results of stress. LÄS MER

  7. 5. Development of nuclear medicine methods for gastric and small bowel motility : effects of GLP-1 on gastric emptying

    Författare :Per Grybäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gastric emptying; ghrelin; glucagon-like peptide-1; 99mTc-HIDA; obesity; radionuclide investigation; small bowel transit.;

    Sammanfattning : The diagnosis of functional disorders of the gastrointestinal (GI) tract requires techniques being both sufficiently sensitive to detect disturbances of the normal physiology and low-invasive enough not to interfere with the properties being studied. The purpose was to set up nuclear medicine methods for assessment of upper GI tract motility and study the effect of glucagon-like peptide-1 (GLP-1) on gastric emptying. LÄS MER
