    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Geriatric nursing; congestive heart failure; insulin resistance; inflammation; obesity; blood sedimentation; apolipoproteins; antioxidants; beta carotene; oxidative stress; registries; epidemiology; risk factors; Äldrevård; Older people and ageing; Äldre och åldrande;

    Sammanfattning : Congestive heart failure (CHF) is a major cause of morbidity and mortality and the identification of modifiable risk factors is crucial in order to diminish suffering of this common disease. The primary aim of this thesis was to investigate novel metabolic risk factors for CHF, with a focus on insulin resistance and inflammation. LÄS MER

  3. 2. Effects of Antioxidants and Pro-oxidants on Oxidative Stress and DNA Damage using the Comet Assay : Studies on Blood Cells from Type 2 Diabetes Subjects and Mouse Lymphoma Cells

    Författare :Rikard Åsgård; Björn Hellman; Leif Busk; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolic syndrome; fruit and vegetable intake; plasma antioxidants; beta-carotene; alpha-tocopherol; inflammation; oxidative DNA damage; lipid peroxidation; mouse lymphoma assay; ROS; nucleotide pool; viability; DNA dye; Toxicology; Toxikologi;

    Sammanfattning : Diet and oral supplements comprise two distinct sources of antioxidants known to prevent oxidative stress. Beneficial effects from antioxidants have been seen for patients at risk for type 2 diabetes.The aim of this thesis was to evaluate the positive effects of antioxidants against oxidative stress and DNA damage in type 2 diabetes subjects.

  4. 3. Roles of Helicobacter pylori infection, host genetic variation, and other environmental exposures in gastric carcinogenesis

    Författare :Christina Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Despite a general declining secular trend of incidence in most parts of the world, stomach cancer is still a major cause of cancer-related death worldwide due to its poor prognosis. Although Helicobacter pylori (H. pylori) infection is an established risk factor for stomach cancer, the true magnitude of the association is still not determined. LÄS MER

  5. 4. Environmental and genetic factors in lung cancer : epidemiologocal and biomolecular studies focusing on nonsmokers

    Författare :Fredrik Nyberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lung cancer; case-control study; smoking misclassification; exposure misclassification; validation; bias; nonsmoker; smoking; environmental tobacco smoke; ETS; diet; biomarker; glutathione S transferase; GSTM1; N-acetyl transferase; NAT2; hypoxanthine-guanine phosphoribosiyl transferase; hprt; DNA; adducts;

    Sammanfattning : Tobacco smoking is the major cause of lung cancer. Other risk factors include exposure to environmental tobacco smoke (ETS), dietary habits and genetic factors. When studying such risk factors, confounding from smoking presents a pervasive methodological problem. LÄS MER
