  2. 1. 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.

  4. 2. Metabolism-dependent activation of food and environmental mutagens in endothelial cells

    Author : Anita Annas; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Abstract : The endothelial cells of blood vessels have been proposed as a target for toxic effects ofxenobiotics in the cardiovascular system. In the present studies, induction of cytochromeP450 1A (CYP1A) enzymes and metabolic activation of food and environmentalmutagens were examined in endothelial cells of rodents, birds, and humans.

  6. 4. Impact of Bifidobacterium longum and Lactobacillus acidophilus on the intestinal microflora and bioavailability of some food mutagens

    Author : Kerstin Orrhage; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The gastrointestinal microflora is a complex ecological system, normally characterised by a flexible equilibrium. The most important role of the microflora, from the point of view of the host, is probably to act in colonisation resistance against exogenous, potentially pathogenic, microorganisms. READ MORE

  7. 5. Isolation, Characterization and Risk Analysis of Organic Micropollutants in Water

    Author : Bo Wigilius; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The work in this thesis primarily aimed at studying and further developing methods for the isolation, fractionation and characterization of organic compounds in water.Suitable concentration methods are a prerequisite for the characterization and risk analysis of such compounds.
