    Sammanfattning : Prostate cancer constitutes the most common malignancy and the most common cause of cancer‐related death in Swedish men. A large body of evidence suggests that inherited genetic variants contribute to both development and progression of prostate cancer. LÄS MER

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

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  4. 4. Vitamin D and multiple sclerosis: epidemiological studies on environmental and genetic risk factors

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Environmental Medicine

    Författare :Maria Bäärnhielm; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Multiple sclerosis (MS) is an autoimmune inflammatory neurological disease with complex aetiology where the causes are not completely known. The main aim of this thesis was to investigate the influence of vitamin D on the risk of developing MS. LÄS MER

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

    Detta är en avhandling från Stockholm : Karolinska Institutet, -

    Författare :Helena Enroth; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helicobacter Pylori; microbiology; epidemiology; diversity; gastric adenocarcinoma; risk factors; coccoid; genomic fingerprinting; strain variation; multiple strain infection; PCR; 2-D PAGE; immunoblotting; CagA; VacA;

    Sammanfattning : 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.
