  1. 1. Antioxidative Properties of Herring (Clupea harengus) Press Juice in Food, In Vitro and In Vivo Model Systems

    Författare :Thippeswamy Sannaveerappa; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; antioxidants; monocytes; washed cod mince; Clupea harengus; LDL oxidation; press juice; oxidation; ORAC; hemoglobin; alpha-tocopherol; herring; in vitro digestion.;

    Sammanfattning : Some species like herring (Clupea harengus) are currently under-utilized due to their small size, dark colour and susceptibility to lipid oxidation. Our hypothesis has been that the high susceptibility of herring to oxidation makes it well equipped with natural antioxidants, both fat and water soluble ones. 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. Effects of Antioxidant and Lipid Lowering Treatment on Risk Factors for Cardiovascular Disease : With special reference to Mixed Tocopherols and Stable Fish Oil

    Författare :Meilin Liu; Afaf Kamal-Eldin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiovascular disease; Antioxidants; Tocopherols; Endothelial constitutive nitric oxide synthase; Superoxide dismutase; Protein kinase C; Fish oils; Fatty acids; Simvastatin; Lipoprotein; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; rättsmedicin; Forensic Medicine;

    Sammanfattning : Vitamin E in food, polyunsaturated fatty acids (PUFAs) and lipid lowering treatment with statins have been found to decrease the risk for cardiovascular disease (CVD) and cardiac death. However, clinical trials revealed no beneficial effect of intake of alpha-tocopherol alone. LÄS MER

  5. 4. Factors related to the occurrence of gastric adenocarcinoma subtypes

    Författare :Anna Mia Ekström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :gastric; cancer; incidence; trend; cardia; Laurén; histologic; misclassification; antioxidant; completeness; vegetable; fruit; occupation; phenoxy; metal; forestry; Helicobacter pylori; smoking;

    Sammanfattning : Gastric cancer is the second most common cancer worldwide, but the etiology remains poorly understood. A spontaneous global decline has reduced the number of victims in most Western countries while Japan and China have screening programs in place due to the magnitude, and the serious prognosis, of this malignant disease.

  7. 5. Low density lipoprotein (LDL) heterogeneity : implications for cardiovascular disease and genetic influence

    Författare :Camilla Skoglund Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Low density lipoprotein; gradient gel electrophoresis; intima-media thickness; atherosclerosis; myocardial infarction; low density lipoprotein oxidation; cholesteryl ester transfer protein; lipoprotein lipase; hepatic lipase; apolipoprotein E; apolipoprotein B; microsomal triglyceride transfer protein; genetics; lipoproteins; metabolism;

    Sammanfattning : The low density lipoprotein (LDL) particle population is heterogeneous with regard to several structural and functional properties that may influence its atherogenic potential. A preponderance of small, dense LDL is associated with an increased risk of coronary heart disease (CHD), and also predicts future CHD events. LÄS MER
