  1. 1. Uptake, induction and distribution of ubiquinone and a-tocopherol

    Författare :Yiyi Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Ubiquinone (UQ) and a-tocopherol are the major lipid-soluble antioxidants in animal tissues. Appropriate amounts of these lipids have to be present in tissues and subcellular membranes. Uptake from the diet was investigated and it was also analyzed to which extent the tissue amount may be increased by induction of biosynthesis. LÄS MER

  3. 2. Antioxidant-Impregnated Polymers / Antioxidant Ability and Interactions with Food

    Författare :Carolina Wessling; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Food and drink technology; shelf-life; interactions; packaging; polymers; BHT; antioxidants; a-tocopherol; Livsmedelsteknik;

    Sammanfattning : Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. LÄS MER

  4. 3. Studies on Cell Injury Induced by Hypoxia-Reoxygenation and Oxidized Low Density Lipoprotein : With Special Reference to the Protectiove Effect of Mixed Tocopherols, Omega-3 Fatty Acids and Transforming Growth Factor-beta1

    Författare :Hongjiang Chen; Tom Saldeen; Christer Sylven; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Tocopherols; fish oil; TGF-β1; NOS; adhesion molecules; MMPs; PKB; MAPK; H-R; Ox-LDL; Myocytes; HCAECs; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : Hypoxia-reoxygenation (H-R) injury is an important clinical phenomenon in patients with coronary artery disease (CAD). Endothelial injury is a critical step in the initiation and progression of atherosclerosis. Therefore, endothelial and cardiomyocyte protection has been considered an effective step in prevention and treatment of CAD. LÄS MER

  5. 4. Fractionated irradiation of salivary glands : loss and protection of function

    Författare :Ulrika Funegård; Thorild Ericson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Irradiation; salivary glands; saliva composition; antioxidants; radioprotection;

    Sammanfattning : Radiotherapy of malignancies in the head and neck often involves the major and minor salivary glands in the radiation field. Adverse effects, such as dry mouth symptoms, are common after such therapy. LÄS MER

  7. 5. Role of phospholipids in neurodegenerative diseases

    Författare :Zhi-Zhong Guan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The structure and composition of brain phospholipids, including also their ether analogues, were investigated and modifications during neurodegeneration were analysed. In order to improve sensitivity and reproducibility, new HPLC methods were developed for separation and quantitation of phospholipids and plasmalogens, followed by quantitation of fatty acids and aldehydes.
