  1. 21. Molecular epidemiologic studies on helicobacter pylori infection and stomach cancer risk

    Författare :Zongli Zheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Helicobacter pylori;

    Sammanfattning : Helicobacter pylori (H. pylori) infection increases stomach cancer risk. The aim of this thesis was to study genetic susceptibility from the host and to develop molecular methods for future characterization of bacterial virulence factors in longitudinal cohorts. LÄS MER

    Sammanfattning : Helicobacter pylori infection is an important cause of chronic active gastritis and peptic ulcer disease and a risk factor for the development of gastric cancer. An attractive strategy in the control of H. pylori infection is the development of a safe and effective therapeutic vaccine. Using a mouse model of H. LÄS MER

  4. 23. Diversity and persistence of Helicobacter pylori

    Författare :Annelie Lundin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Helicobacter pylori; genomic diversity; cag pathogenicity island; Nudix hydrolase;

    Sammanfattning : Helicobacter pylori is an exceptionally diverse bacterial species, and every infected individual harbors a unique strain, apart from the strain concordance found in some families. The infection is usually acquired during childhood and once established, persists for life unless treated with antibiotics. LÄS MER

    Författare :Åsa Lindgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Natural killer cells; Helicobacter pylori; gastric cancer; IFN-γ; TLR;

    Sammanfattning : Helicobacter pylori infection is one of the most wide-spread infections in the world and causes a chronic inflammation in the gastrointestinal mucosa characterised by increased production of IFN-γ and is associated with an increased risk of developing gastric cancer. The mechanisms behind the development of gastric cancer in H. LÄS MER

  7. 25. Helicobacter pylori and Chlamydia pneumoniae in primary care- cardiovascular and gastrointestinal aspects
