  1. 6. Helicobacter pylori interference with the L-arginine/NO pathway in the upper gut

    Författare :Charlotte Von Bothmer; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acid; bicarbonate; duodenal ulcer; Helicobacter pylori; host defence; mucosa; nitric oxide; nitric oxide synthase;

    Sammanfattning : Helicobacter pylori causes chronic gastritis and sometimes peptic ulcers but the pathogenesis is not fully understood. H. pylori-infected individuals with duodenal ulcer have an impaired duodenal mucosal bicarbonate secretion (DMBS) in response to acid. NO is an important signalling molecule in the body. LÄS MER

  3. 7. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells

    Författare :Anna Lundgren; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; T cells; regulatory T cells; dendritic cells; T-cell recruitment;

    Sammanfattning : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

  4. 8. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER

  5. 9. Gastrointestinal Physiology and Results following Bariatric Surgery

    Författare :Jakob Hedberg; Magnus Sundbom; Näslund Erik; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bariatric surgery; gastric bypass; biliopancreatic diversion with duodenal switch; PYY; stomal ulcer; gastric emptying; Surgery; Kirurgi; Kirurgi; Surgery;

    Sammanfattning : The number of operations for morbid obesity is rising fast. We have examined aspects of postoperative physiology and results after bariatric surgery. The pH in the proximal pouch after Roux-en-Y gastric bypass (RYGBP) was investigated with catheter-based and wire-less technique. LÄS MER

  7. 10. Peptic ulcer disease in an adult population : the Kalixanda study – a population-based endoscopic study

    Författare :Pertti Aro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Epidemiology; esophagogastroduodenoscopy EGD ; peptic ulcer disease PUD ; population-based.;

    Sammanfattning : Introduction: The pattern of symptoms and perception of disease among patients seeking care does, due to health care seeking behaviour, most probably not reflect the true health status in the general population. Upper esophagogastroduodenoscopy (EGD) is considered to be gold standard for upper gastrointestinal (GI) disease assessment, but is seldom used in epidemiological studies. LÄS MER
