  2. 1. Helicobacter pylori and its Association with Gastric and Oesophageal Carcinomas

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

    Abstract : 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. READ MORE

  4. 2. Helicobacter spp. interactions with mucins: adhesion and mucin regulation of pathogen proliferation and gene expression

    Author : Emma C Skoog; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter; mucin; glycosylation; Lactobacillus; adhesion; proliferation; gene expression; CagA; SabA; BabA; ArsS; Fur;

    Abstract : Helicobacter pylori colonizes the gastric mucosa of approximately half of the world’s population and is a risk factor for gastritis, peptic ulcers and gastric cancer. H. pylori is surrounded by, and adheres to, the heavily glycosylated mucins that build up the mucus layer. The carbohydrate structures on the mucins that act as ligands for H. READ MORE

  6. 4. Aspects of Helicobacter pylori transmission

    Author : Mårten Kivi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori; epidemiology; transmission; family; two-stage; missing data; molecular typing; CagA; cag pathogenicity island; variability; microarray;

    Abstract : The bacterium Helicobacter pylori infects the gastric mucosa of about half of the world's population. The infection causes gastritis and contributes to the development of peptic ulcer disease and gastric cancer. H. READ MORE

  7. 5. Helicobacter pylori bacterial diversity and human disease : microbiological and epidemiological studies with special reference to gastric cancer

    Author : Helena Enroth; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter Pylori; microbiology; epidemiology; diversity; gastric adenocarcinoma; risk factors; coccoid; genomic fingerprinting; strain variation; multiple strain infection; PCR; 2-D PAGE; immunoblotting; CagA; VacA;

    Abstract : The aims of this thesis were to explore if the coccoid form of H. pylori is a degenerative, dead form of the bacteria. We also wanted to study if multiple strain infections of H. pylori existed in Swedish subjects, if the strain variations were connected to certain disease groups, and if specific protein markers could be found in H.
