  1. 1. Redox Regulation and Stress Responses - Studies in Bacillus subtilis

    Författare :Jonas Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox sensor; oxygen sensor; reactive nitrogen species; RNS; Biology; Biologi; Microbiology; bacteriology; virology; mycology; bakteriologi; Mikrobiologi; virologi; mykologi; Bacillus subtilis; Rex; yjbI; ydiH; yjbH; redox regulation;

    Sammanfattning : Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. LÄS MER

  2. 2. Signalling in plant mitochondria. Redox regulation of gene expression & characterisation of a pea nucleoside diphosphate kinase

    Författare :Martha L Escobar Galvis; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondrial gene expression; redox; respiratory complex II; NDPK; protein interactions; heat-stress; Växtbiokemi; Plant biochemistry;

    Sammanfattning : This work contributes to our understanding of mitochondrial responses to changing environmental conditions in plants. The first part of this thesis is focused in the study of redox regulation of mitochondrial gene expression. By using inhibitors, the redox state of the components of the mitochondrial respiratory chain was selectively affected. LÄS MER

  3. 3. Liquid Redox Electrolytes for Dye-Sensitized Solar Cells

    Författare :Ze Yu; Lars Kloo; Md K Nazeeruddin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; electrolytes; ionic liquids; redox couples; additives;

    Sammanfattning : This thesis focuses on liquid redox electrolytes in dye-sensitized solar cells (DSCs). A liquid redox electrolyte, as one of the key constituents in DSCs, typically consists of a redox mediator, additives and a solvent. LÄS MER

  4. 4. Intricate aspects of the thioredoxin system in redox signaling

    Författare :Marcus Cebula; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Reversible modifications of redox sensitive protein thiols by reactive oxygen and nitrogen species have emerged as a major posttranslational mechanism that affects the function of the respective proteins and therewith all downstream events. These modifications can be reversed by redox catalysts of which the thioredoxin system forms one of the most prominent. LÄS MER

  5. 5. Mineralisation rates of natural organic matter in surface sediments affected by physical forces

    Författare :Carina Ståhlberg; Bo Svensson; Lars Rahm; David Bastviken; Anders Tengberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sediment; Organic matter mineralisation; Organic matter degradation; Redox; Electron acceptor; Resuspension; Advective pore water flow; Other chemistry; Övrig kemi;

    Sammanfattning : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. LÄS MER
