  1. 6. Mucosal T-cell and cytokine responses in Helicobacter pylori-infected duodenal ulcer patients

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Jorge Alberto Arroyo Vázquez; Göteborgs universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 8. Regulation of Duodenal Mucosal Barrier Function and Motility : The Impact of Melatonin

    Författare :Anna Sommansson; Markus Sjöblom; Olof Nylander; Oliver Bachmann; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Sammanfattning : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 10. Trafficking of Human Dendritic Cells and B cells in Helicobacter pylori-induced Gastritis

    Författare :Malin Hansson; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; migration; homing; dendritic cells; B cells; gastric mucosa;

    Sammanfattning : Infection with the bacterium Helicobacter pylori is widespread throughout the world, and is associated with development of gastric and duodenal ulcer disease as well as gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma. The infection generally leads to a large infiltration of immune cells, among them dendrite cells (DC) and IgA-secreting cells. LÄS MER
