  1. 1. 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

  3. 2. Nitrate, Nitrite and Nitric Oxide in Gastric Mucosal Defense

    Författare :Joel Petersson; Lena Holm; Jon Lundberg; Mia Phillipson; Matthew Grisham; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary nitrate; mucus gel layer; mucosal blood flow; mucus thickness; laser-Doppler flowmetry; mucosal damage; intra-vital microscopy; mucosal permeability; Physiology; Fysiologi;

    Sammanfattning : The human stomach normally contains high levels of bioactive nitric oxide (NO). This NO derives from salivary nitrate (NO3-) that is converted to nitrite (NO2-) by oral bacteria and thereafter non-enzymatically reduced in the acidic gastric lumen to NO. LÄS MER

  4. 3. Identification and characterisation of bacteria based on 16S rDNA techniques with special reference to Helicobacter pylori in the gastro-intestinal tract

    Författare :Annika Tiveljung; Anders Sjöstedt; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The overall aim of this study was to establish molecular techniques for the detection and identification of "difficult to grow" - bacteria in mixed bacterial populations in clinical samples without the need for culturing procedures.Material and Methods: Thirty-nine strains of Mobiluncus were used as a model system for phylogenetic classification of fastidious bacteria based on 16S ribosomal DNA (rDNA) sequences.

  5. 4. Gastrointestinal Disorders in Women

    Författare :Rita Gustafsson; Gastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Abstract: This doctoral thesis has sought to clarify the influence of gender in gastrointestinal (GI) disorders. Women with different hormone profiles were investigated, their colonic microbiota was characterized, and the impact of lifestyle and risk factors for GI disease were examined. LÄS MER

  7. 5. Experimental Helicobacter pylori infection in an animal model

    Författare :Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. LÄS MER
