  2. 1. The Duodenal Mucosal Bicarbonate Secretion : Role of Melatonin in Neurohumoral Control and Cellular Signaling

    Author : Markus Sjöblom; Gunnar Flemström; Olof Nylander; Karl EO Åkerman; Per M. Hellström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; alkaline secretion; central nervous system; duodenal enterocyte; duodenal ulcer; duodenum; enterochromaffin cell; human; intraarterial; intracellular calcium; intracerebroventricular; melatonin; rat; vagal nerve; Fysiologi; Physiology; Fysiologi;

    Abstract : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. READ MORE

  4. 2. Mucosal T-cell and cytokine responses in Helicobacter pylori-infected duodenal ulcer patients

    Author : Erika Strömberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter pylori; mucosal immunology; antrum; duodenum; duodenal ulcer; asymptomatic; epithelial cells; cytokines; T cells;

    Abstract : Helicobacter pylori colonizes the human stomach and areas of gastric metaplasia in the duodenum. The bacterium is the major cause of chronic active gastritis and peptic ulcer disease and is a risk factor for the development of gastric adenocarcinoma and lymphoma. READ MORE

  5. 3. Stent treatment of perforated duodenal ulcer - physiology and clinical aspects

    Author : Jorge Alberto Arroyo Vázquez; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stent; Gastroscopy; Perforated duodenal ulcer; Proton Pump inhibitor; Gastric bacterial flora; Gastric pH; Pylorus; EndoFLIP™; Pyloric motility;

    Abstract : Background The incidence of perforated duodenal ulcer is decreasing but still constitutes a life-threatening complication to peptic ulcer disease. Abdominal contamination from gastric or duodenal content occurs during perforations. READ MORE

  6. 4. Complications to peptic ulcer and peptic ulcer surgery

    Author : Kristina Åhsberg; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Long term effects after peptic ulcer surgery still exert an influence on some patient groups. Partial gastrectomy increases the risk of gastric carcinoma more than 20 years after surgery and enterogastric reflux is regarded as the main ethiological factor. READ MORE

  7. 5. Regulatory CD4+FOXP3+ T cells in Helicobacter pylori-induced disease

    Author : Bert Kindlund; Göteborgs universitet; []
    Keywords : Regulatory T cells; Helicobacter pylori; duodenal ulcer; gastric cancer; FOXP3;

    Abstract : Helicobacter pylori colonize the gastric or duodenal mucosa of approximately half of the worlds’ population. Although most individuals are asymptomatic, H. pylori infection cause peptic ulcers or gastric cancer in 10-15 % and 1-2 %, respectively, of the infected individuals. READ MORE
