  1. 21. Characterization of ion transport proteins involved in chloroplast function from land plants and algae

    Författare :Emilija Dukic Marinkov; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Evolved around 2.4 billion years ago and even earlier, according to the new geochemical evidence, oxygenic photosynthesis is the crucial turning point in the history of our planet. LÄS MER

  3. 22. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

    Sammanfattning : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

  4. 23. A genetic approach to the identification of new components regulating development in Arabidopsis thaliana

    Författare :Ingela Fridborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Two new genes involved in important processes of plant development were identified in the model plant Arabidopsis thaliana. The genes were isolated from mutants generated through insertional mutagenesis based on a transposon tagging approach. LÄS MER

  5. 24. Flexible and transparent biological electric power sources based on nanostructured electrodes

    Författare :Elena González Arribas; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biocatalysis; Biological fuel cells; Biosupercapacitors; Flexible biodevice; Solar biosupercapacitor; Enzymatic fuel cell; Indium tin oxide; Conducting polymer; Non-invasive; Smart contact lens; Sciences;

    Sammanfattning : Portabel medicinteknisk utrustning framträder alltmer som en av de mest lovande metoderna för vårdövervakning och personlig behandling. Förebyggande vård och hantering av kroniska sjukdomar är resurskrävande och en överföring av det konventionella sjukhuscentrerade sjukvårdssystemet till ett individcentrerat vårdsystem skulle vara samhällsekonomiskt gynnsam.

  7. 25. 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.
