  2. 21. Dietary heterocyclic amines and human cancer risk

    Author : Katarina Augustsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cancer; colon; rectum; bladder; kidney; human; heterocyclic amines; meat;

    Abstract : Heterocyclic amines formed in meat during cooking are multi-site animal carcinogens and form DNA adducts in human tissues, but their relevance to human carcinogenesis has yet to be determined. The aim of this thesis was to investigate, by epidemiological methods, whether heterocyclic amines are responsible for part of the diet-related cancer burden in humans. READ MORE

  4. 22. Modifying Cooking Practices to Reduce the Formation of Heterocyclic Amines

    Author : Elna Hallgard; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; cancer; frying; mutagens; beefburger; chicken; heterocyclic amines; cooking;

    Abstract : Commonly cooked meat dishes contain heterocyclic amines (HAs) at ng/g levels. HAs are animal carcinogens, form DNA adducts in human tissues, and have been associated with increased risk of cancer in epidemiological studies, and it is thus recommended that human intake be decreased.

  5. 23. Lung toxicity of airborne nanoparticles - focus on development of an advanced in vitro exposure system

    Author : Siiri Latvala; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Inhalation exposure to airborne particles, such as nickel, increases the risk for several respiratory tract diseases. Even though the effects of nickel have been extensively studied, the data for some nickel particle types is currently inconclusive. READ MORE

  6. 24. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction

    Author : Hang Li; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases.

  7. 25. Characterization of toxicological effects of a novel in vivo benzo[a]pyrene metabolite in colonic cells

    Author : Mirjam Nordling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Polycyclic aromatic hydrocarbons; benzo[a]pyrene; colon cancer; genotoxicity; oxidative DNA damage.;

    Abstract : Cancer of the colon and rectum is the third most common cancer form in the world. Where the majority of cases fall into the category of sporadic colorectal cancer (CRC), lifestyle and diet have been found to be important risk factors associated with CRC. READ MORE
