  2. 6. Aspects on the functional characteristics of the Roux-limb after Gastric Bypass surgery

    Author : Per Björklund; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; obesity; bariatric surgery; meal size; morphology; intestinal motility; high resolution manometry; abdominal pain; opioid analgesics;

    Abstract : Background: Bariatric surgery, and particularly the Roux-en-Y Gastric Bypass (RYGBP) procedure, has highlighted the central role of the gastrointestinal tract in the regulation of body weight and metabolism. The Roux-limb is the part of the small intestine that has become the food recipient after RYGBP and has generally been very little studied. READ MORE

  4. 7. Deciphering cell motility and spatial sensing of intestinal cell types using an ex vivo intestinal model

    Author : Anna Webb; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The intestine is a highly organized tissue with two distinct regions: the crypt and the villus. When stem cells divide at the crypt bottom, half of their progeny migrates upwards towards the villus, where they differentiate into various cell types, including the abundant absorptive enterocytes.

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

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

    Abstract : 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. READ MORE

  6. 9. Melatonin and its receptors in the normal human gastrointestinal tract, pancreas and in small intestinal neuroendocrine tumours

    Author : Fanny Söderquist; Janet Cunningham; Lisa Ekselius; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Melatonin, “the hormone of darkness” is well known to regulate sleep and circadian rhythm. However, melatonin is also present in numerous peripheral tissues and the number of actions assigned to this neurohormone is growing steadily. READ MORE

  7. 10. Capsule endoscopy in the diagnosis of small bowel disease

    Author : Charlotte Höög; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Capsule endoscopy (CE) is a method for examining the small bowel by means of an ingested encapsulated video camera, propelled by peristalsis, to continuously take images during its passage through the gastrointestinal tract. The method has been in clinical use in Sweden since 2002 and is considered user-friendly and well tolerable by patients. READ MORE
