  2. 1. Roux-en-Y gastric bypass - clinical outcome and mechanisms of action

    Author : Malin Werling; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Roux-en-Y gastric bypass; Obesity; Bariatric surgery; Energy chamber; Gastrointestinal hormones; GLP-1; PYY; Ghrelin; Energy expenditure; Body composition; Vertical Banded Gastroplasty; Indirect calorimetry; Overweight treatment; Weight loss;

    Abstract : Roux-en-Y gastric bypass (gastric bypass) is an effective surgical technique for treating morbid obesity. The objective of this thesis is to increase knowledge of long-term outcomes of gastric bypass surgery and to elucidate some of the associated mechanisms of action. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Gastrointestinal Permeability and Motility in Inflammatory Bowel Disease

    Author : Anas Kh. Al-Saffar; Per Hellström; Dominic-Luc Webb; Åsa Keita; Uppsala universitet; []
    Keywords : Gastrointestinal motility; intestinal permeability; Mucosal; Ghrelin; Medicinsk vetenskap; Medical Science;

    Abstract : Synchronized motility, permeability and secretory (hormones and enzymes) events are integral to normal physiology. Smooth muscle syncytium operates with enteric nervous system (ENS) and endocrine signalling to accommodate, mix and control passage of ingested materials. READ MORE

  6. 4. Ghrelin action on gastrointestinal functions and appetite in rat and man

    Author : Fredrik Levin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ghrelin; ghrelin-receptors; gastrointestinal motility; migrating myoelectric complex; gastric acid secretion; gastric emptying; appetite; food intake; disinhibition; restraint; hunger; obesity;

    Abstract : To study the effect of ghrelin on the contractility of smooth muscle strips in vitro as well as the effects on fasting small bowel motility and acid secretion in vivo in rats and gastric emptying in rats and humans. To study the effect of peripherally administered ghrelin on plasma levels of glucose, insulin, glucagon, orexin A (OXA), somatostatin and gastrin in rats and ghrelin, cholecystokinin (CCK), glucagonlike peptide-1 (GLP-1), peptide YY (PYY) and motilin in humans.

  7. 5. The role of incretin peptides and ghrelin in upper gut motility and metabolic control

    Author : Therese Edholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Metabolic control is essential for the individual and is strictly regulated via a wide range of factors. One important mechanism in maintaining an adequate blood sugar level is the regulation of insulin release and gastric emptying rate by gastrointestinal (GI) hormones. READ MORE
