1. 21. Medical interventions and gastric cancer risk : an observational approach

   Författare :Katja Fall; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Gastric cancer; cardia cancer; histological subtypes; H. pylori; antibiotic treatment; eradication; aspirin; NSAIDs; cholecystectomy; reactive gastritis; cohort; epidemiology;

   Sammanfattning : Helicobacter pylori infection is undoubtedly the most important risk factor for gastric cancer. A causal relationship with gastric cancer, however, has not been clearly established and the carcinogenic mechanism is still ambiguous. LÄS MER

3. 22. Helicobacter pylori and its Association with Gastric and Oesophageal Carcinomas

   Författare :Henrik Simán; Internmedicin - epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastroenterologi; Gastro-enterology; Western blot; CagA; Helicobacter pylori; Gastric adenocarcinoma; Oesophageal carcinoma;

   Sammanfattning : Helicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. LÄS MER

4. 23. Helicobacter pylori infection in a mouse model: Development, optimization and inhibitory effects of antioxidants

   Författare :Xin Wang; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; Microbiology; mice; Helicobacter pylori; gastritis; lymphoma; antioxidant; diet; Th1 and Th2; cytokines; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Helicobacter pylori is a human pathogen strongly associated with chronic type B gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma. Our aims were to establish a mouse model of H. pylori infection, to study pathogenesis of gastritis and gastric cancer and to investigate new treatment strategies in this model. LÄS MER

5. 24. Helicobacter pylori Sialic Acid-Specific Surface Lectin

   Författare :Siiri Hirmo; Enheten för infektionssjukdomar; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bakteriologi; mycology; Mikrobiologi; virology; bacteriology; haemagglutinin; Helicobacter pylori; sialic acid; sialidase; gastrointestinal mucin; milk glycoprotein; Microbiology; resonant mirror biosensor; virologi; mykologi;

   Sammanfattning : Helicobacter pylori is a gastric pathogen colonising the gastric mucus layer and epithelium of gastric tissue and is associated with chronic type B gastritis and peptic ulcer disease. The attachment of H. pylori to gastric epithelial cells involves several structures recognised by specific bacterial surface proteins. LÄS MER

7. 25. Aspects of gastroesophageal reflux and risk for esophageal cancer : an epidemiological approach

   Författare :Weimin Ye; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Gastroesophageal reflux; anti-reflux surgery; esophagus; adenocarcinoma; squamous- cell carcinoma; H. pylori; gastric atrophy; DNA repair gene; polymorphism; cohort study; case-control study; relative risk;

   Sammanfattning : Aims: The aims of this study were to confirm, in a prospective study, the link between gastroesophageal reflux. and risk of adenocarcinoma of the esophagus and gastroesophageal junction observed in retrospective studies, to investigate into the effects of anti-reflux surgery, and to shed light on some possible mechanisms behind the alleged carcinogenicity.
