2. 1. Gastric electrical stimulation. Studies in patients with intractable nausea and vomiting

   Author : Stina Andersson; Göteborgs universitet; []
   Keywords : gastric electrical stimulation; gastroparesis; gastroscopy; vomiting; gastric accommodation; drinking test; dyspepsia;

   Abstract : The most severe cases of gastroparesis are refractory to drugs. In the 1990s gastric electrical stimulation (GES) was introduced for treatment of nausea and vomiting in patients with diabetic and idiopathic gastroparesis. The electrodes and neurostimulator are usually placed with laparoscopy. READ MORE

4. 2. The Renin Angiotensin System in the Human Esophageal Mucosa − expression, actions and potential involvement in reflux disease

   Author : Eleonora Björkman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endoscopic biopsies; epithelial electrical current; epithelial electrical resistance; esophageal mucosae; gastroesophageal reflux disease; mucosal barrier integrity; renin angiotensin system;

   Abstract : The renin angiotensin system (RAS) is a classical endocrine system, regulating body fluid balance and blood circulation. Recent research has shown that the system is being also locally expressed and active in several organs and tissues. READ MORE

5. 3. Peripherally administered choleocystokinin-8 increases neurotrophins in the brain

   Author : Paola Tirassa; Karolinska Institutet; Karolinska Institutet; []
   Keywords : NGF; BDNF; CCK-8; glutamate; GABA; CCK receptors; hypothamalus; hippocampus; Choline Acetyltransferase; fimibria-fornix transection; vagotomy; vagal stimulation; RT-PCR; ELISA;

   Abstract : The aim of this thesis was to test the hypothesis that the gastric hormone Cholecystokinin-8 (CCK-8) can modulate the production of Nerve Growth Factor (NGF) in the brain. NGF is the first discovered and the best characterized neurotrophic factor which plays a crucial role in the survival and development of basal forebrain cholinergic neurons (BFCN). READ MORE

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

   Author : Anne-Barbara Witte; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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”. READ MORE

7. 5. Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

   Author : Mikael Ekelund; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; Gastroenterologi; Gastro-enterology; Fysiologi; Physiology; total parenteral nutrition; supersensitivity; plasticity; intestinal bypass; interstitial cells of Cajal; goblet cells; eosinophils; adaptation; enteric nervous system;

   Abstract : Abolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. READ MORE
