  4. 18. Inflammation in experimental neonatal brain injury and in a clinical study of preterm birth; involvement of galectin-3 and free radical formation

    Författare :Christina Doverhag; Göteborgs universitet; []
    Nyckelord :preterm labour; premature prelabour rupture of membranes; chorioamnionitis; hypoxia-ischemia; neonatal brain injury; NADPH oxidase; galectin-3; MMP-9; ascorbyl radicals; antioxidative capacity;

    Sammanfattning : Introduction; Intrauterine infection/inflammation is associated with preterm delivery (PTD) and severe neonatal morbidity. Inflammation is also important in the secondary neurotoxic cascade leading to perinatal brain injury. LÄS MER

  5. 19. Thiyl radicals, reaction kinetics and redox chemistry

    Författare :Rong Zhao; KTH; []
    Nyckelord :;

    Sammanfattning : In focusing on the free radical chemistry of thiyl radicals,two importantclasses are dealt with, namely, the amino acidalkylthiyl and the acylthiyl radicals, where pulse radiolysisand steady state γ-radiolysis are applied.Amino acid thiyl radicals (RS•), are important in manybiological systems,as intermediates in the repair reactions ofthiols towards targeted carbon-centeredradicals and ascatalytic centers in many enzymatic reactions.

  7. 20. The involvement of calcium and membrane fusion events in neutrophil secretion and respiratory burst

    Författare :Daniel Granfeldt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; calcium; regulated secretion; membrane fusion; SOC; arachidonic acid; intracellular fusion; oxygen free radicals; phagocytosis;

    Sammanfattning : Neutrophil granulocytes play an important role in host defence during the early stages of microbial infection. The neutrophils have to leave the blood stream and migrate out into the tissue where they are able to phagocytose and kill microbes as well as dispose of cell debris from damaged tissues. LÄS MER
