  1. 1. Oxidative Damage in Fish Used as Biomarkers in Field and Laboratory Studies

    Författare :Bethanie Carney Almroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish; oxidative stress; antioxidant enzymes; glutathione; protein carbonyls; lipid peroxidation; biomarkers; pollution; aging;

    Sammanfattning : Many toxic xenobiotics entering into the aquatic environment exert their effects through redox cycling. Oxidative stress, incorporating both antioxidant defences as well as oxidative damage, is a common effect in organisms exposed to xenobiotics in their environment. LÄS MER

  3. 2. Exploring Novel Catalytic Chalcogenide Antioxidants

    Författare :Henrik Johansson; Lars Engman; Helena Grennberg; Troels Skrydstrup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; catalytic; toxicity; ROS; neutrophil; glutathione peroxidase mimic; macrophage.; Organic chemistry; Organisk kemi; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. LÄS MER

  7. 5. Selenium Compounds and Antioxidant Capacity in Bovine Milk. Studies on Glutathione Peroxidase, Bioavailability and Electrochemical Techniques

    Författare :Jun Chen; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; amperometry; voltammetry; antioxidant capacity; ileostomy; bioavailability; glutathione peroxidase; bovine milk; selenium;

    Sammanfattning : The efficacy and function of antioxidants have been intensively studied in foods and other biological systems in recent decades. This thesis concerns different aspects of the antioxidant properties of bovine milk, with emphasis on measurement of the total antioxidant capacity (TAC), the activity of the selenium-containing glutathione peroxidase (GSHPx), and the bioavailability of selenium from bovine milk in humans.
