  1. 11. 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. 12. Irritable bowel syndrome. Pathophysiological and clinical aspects

    Författare :Magnus Simrén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irritable bowel syndrome; manometry; colonic perception; visceral hypersensitivity; lipids; gastrointestinal peptides; food; quality of life; anxiety; depression; fatigue;

    Sammanfattning : Irritable bowel syndrome (IBS) is characterized by abdominal pain and/or discomfort related to abnormal bowel habits. Gastrointestinal (GI) motility disturbances, visceral hypersensitivity and psychological factors are involved in the pathophysiology of IBS. LÄS MER

  4. 13. Molecular evolution of the neuropeptide Y receptor family : Insights from mammals and fish

    Författare :Amanda Wraith; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Most genes in the genomes of vertebrates form families with multiple members that are more or less closely related. This thesis concerns investigations of the neuropeptide Y (NPY) family of peptides and the family of receptors to which these peptides bind, the NPY receptors. LÄS MER

  5. 14. Functional Studies of the Neuropeptide Y System : Receptor-Ligand Interaction and Regulation of Food Intake

    Författare :Helena Åkerberg; Dan Larhammar; Rickard Malmström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropeptide Y; G-protein coupled receptor GPCR ; site-directed mutagenesis; pancreatic polypeptide; food intake; dog; Pharmacology; Farmakologi;

    Sammanfattning : The members of the mammalian neuropeptide Y family, i.e. the peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), are all involved in regulation of food intake. In human and most other mammals they act via receptors Y1, Y2, Y4 and Y5. LÄS MER

  7. 15. Alcohol and the effect on some appetite-regulating hormones in man

    Författare :Jan Calissendorff; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Leptin; ghrelin; octanoylated; PYY3-36; GLP-1; obestatin; alcohol; NPY; IGF-1; IGFBP-1; insulin; glucose; testosterone; cortisol; catecholamines;

    Sammanfattning : Beverage containing alcohol has been used for centuries to stimulate appetite. Ingestion of a moderate amount of alcohol increase energy intake. Regulation of food intake is complex. Several factors cooperate such as neural impulses from sensory organs; sight, smell, gut distension, social setting, memory, current energy status and hormones.
