  2. 1. Oxidation of marine oils during in vitro gastrointestinal digestion and its effects on stress in human intestinal Caco-2 cells

    Author : Cecilia Tullberg; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; human digestive fluids; LC n-3 PUFAs; Caco-2 cells; marine oils; HNE; MDA; in vitro digestion; HHE; gastrointestinal; aldehydes;

    Abstract : Marine oils are attracting public interest due to the preventive effects, e.g., on inflammation, which are linked to the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). However, LC n-3 PUFAs are highly susceptible to oxidation, which could interfere with their positive effects. READ MORE

  4. 2. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Author : Karin Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

    Abstract : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. READ MORE

  5. 3. Grazer-induced responses in marine phytoplankton

    Author : Johanna Bergkvist; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; defence; dinoflagellate; diatoms; paralytic shellfish toxins; polyunsaturated aldehydes; chain formation;

    Abstract : Phytoplankton are the most important primary producers in the world’s oceans, yet little is known of how they avoid the constant threats from the pelagic grazers. From land it is well known that plants defend themselves by having thorns or producing compounds unpalatable to grazers. READ MORE

  6. 4. In vivo dosimetry of aldehydes and studies on the origin of malonaldehyde

    Author : Antti Kautiainen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Aldehydes are electrophilic reagents that bind to nucleophilic sites in macromolecules andmany of them have been shown to possess cytotoxic and genotoxic properties.The aim of this study was to develop an analytical method for the measurement of reactionproducts (adducts) of aldehydes with hemoglobin (Hb) and to apply this method for in vivodosimetry of endogenously formed aldehydes, particularly malonaldehyde (MA).

  7. 5. Analysis of DNA adducts of some low molecular weight aldehydes : methods development and application in human biomonitoring

    Author : Jia-Long Fang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Malondialdehyde (MA), acetaldehyde (Aa) and methylglyoxal (MG) are ubiquitously present in the environment and endogenously formed in animals and humans. They have been shown to be genotoxic and to readily react with DNA to form DNA adducts under physiological conditions. READ MORE
