  1. 21. Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa : with special reference to cryopreservation

    Författare :Paweena Thuwanut; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation. The ROS and lipid peroxidation can be detected during preparation and cryopreservation of mammalian spermatozoa. LÄS MER

  3. 22. Oxidative stress and mitochondrial function : role of ubiquinol as antioxidant

    Författare :Patrik Andrée; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Over the last three decades it has been established that biquinone (coenzyme Q), in addition to its function as an electron and proton carrier in the respiratory chain, acts in its reduced form (ubiquinol) as an antioxidant. The main theme of this thesis is a study of the antioxidant function of ubiquinol in preparations of beef heart submitochondrial particles, which consist of inverted vesicular fragments of the inner mitochondrial membrane.

  4. 23. Nutrition and Oxidative Parameters in Pregnancy, Size at Birth and Metabolic Status of the Offspring at 4.5 Years : The MINIMat Trial in Rural Bangladesh

    Författare :Emma Lindström; Eva-Charlotte Ekström; Lars-Åke Persson; Samar Basu; Tessa Roseboom; Uppsala universitet; []
    Nyckelord :Pregnancy; micronutrient deficiency; anemia; birth size; food supplementation; micronutrient supplementation; metabolic status; childhood; International Health; Internationell hälsa;

    Sammanfattning : Undernutrition and oxidative stress in fetal life and infancy may lead to adverse health outcomes in the offspring. We studied nutrition and oxidative parameters in pregnancy and their associations with birth anthropometry and metabolic status in the children. LÄS MER

  5. 24. Age pigments and the biochemical basis of their formation

    Författare :Dazhong Yin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The autofluorescent, yellow-brown pigments that accumulate over time inbiological organisms are called age pigments. Lipofuscin, known as a hallmark of aging, refers to intracellular age pigments that accumulate mainly in the lysosomes of postrnitotic cells. LÄS MER

  7. 25. 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
