    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; allergic rhinits; diesel exhaust; airway inflammation; oxylipins; metabolomics; antioxidants; SVCT2; bronchoscopy; lungmedicin; Lung Medicine;

    Abstract : Allergic airway disease, i.e. allergic rhinitis (AR) and asthma, is a common health problem. The prevalence is increasing in most countries of the world. READ MORE

  4. 2. Mass Spectrometric Analysis of Oxylipins : Application to Cytochrome P450-Dependent Metabolism

    Author : Tomas Nilsson; Ernst Oliw; Johan Bylund; Mikael Hedeland; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epoxyalcohols; fatty acids; hydroperoxides; electrospray ionization; ichthyosis; CYP4; linear ion trap; fragmentation mechanism; Pharmaceutical pharmacology; Farmaceutisk farmakologi; Biochemical Pharmacology; Biokemisk farmakologi;

    Abstract : Cytochrome P450 (CYP) family 4 constitutes monoxygenases responsible for hydroxylation of fatty acids and other lipids. For example, CYP4F3 metabolizes leukotrienes and CYP4F8 prostaglandin H. Importantly, six of the twelve CYP4 enzymes are orphans, i.e. READ MORE

  5. 3. Plant Oxylipins and Lipid Transfer Proteins in Defense : - It’s all about the fat

    Author : Per Fahlberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Oxylipins, the oxygenated metabolites of polyunsaturated fatty acids (PUFAs), are found in many eukaryotic organisms. In plants, several enzymes can produce different types of oxylipins, and the chloroplast structural galactolipids mono- and digalactosyl diacylglycerol (MGDG and DGDG, respectively) are examples of sources of substrate PUFAs.
