  1. 16. Experimental and Clinical Studies of Oxidative Stress in Pre-Eclampsia

    Författare :Peppi Nash; Ulf Eriksson; Matts Olovsson; Leif Jansson; Lucilla Poston; Uppsala universitet; []
    Nyckelord :Obstetrics and gynaecology; Pre-eclampsia; Oxidative stress; Diabetes; Placenta; Rat; Antioxidants; Suramin; Vitamin E; Vitamin C; PAI-1; PAI-2; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Impaired placentation and oxidative stress are proposed to play major roles in the pathogenesis of pre-eclampsia (PE). It has recently been pointed out that PE might be more than one disease and may have several different pathogeneses. LÄS MER

  3. 17. Oxidative Stress, Angiogenesis and Inflammation in Normal Pregnancy and Postpartum

    Författare :Maria Palm; Ove Axelsson; Samar Basu; Charlotta Grunewald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; inflammation; IL-6; F2-isoprostanes; oxidative stress; Pentraxin 3; PGF2α; PlGF; pregnancy; sFlt1; TNF-α; VEGF-A; Obstetrik och gynekologi; Obstetrics and Gynaecology; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The aims were to investigate oxidative stress (I), angiogenesis (II) and inflammation (III-IV) in healthy women during pregnancy and postpartum. Oxidative stress was estimated by measurement of 8-iso-PGF2α and the antioxidants α- and γ-tocopherol. LÄS MER

  4. 18. Endothelium-Dependent Vasodilation and Oxidative Stress in Chronic Renal Failure

    Författare :Margus Annuk; Ola Samuelson; Uppsala universitet; []
    Nyckelord :Medical sciences; endothelium; oxidative stress; chronic renal failure; L-arginine; diclofenac; erythropoietin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Internal Medicine; invärtesmedicin;

    Sammanfattning : Cardiovascular disease (CVD) is the major cause of death in patients with chronic renal failure (CRF). Endothelial function and oxidative stress (OS) have previously been shown to be important in the pathogenesis of CVD. In this thesis, the endothelium-dependent vasodilatation (EDV) and OS were investigated in the patients with CRF. LÄS MER

  5. 19. Coordination of two different genomes in response to light and stress

    Författare :Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Sammanfattning : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. LÄS MER

  7. 20. Endogenous and Exogenous Drivers of Oxidative Stress and Inflammation in Preeclampsia

    Författare :Åsa Nääv; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxidative stress; Air Pollutants: adverse effects; Placenta; Preeclampsia pregnancy;

    Sammanfattning : Preeclampsia (PE), is a pregnancy related condition afflicting 3-8% of all pregnancies and a main cause of maternal and infant morbidity and mortality. It is thought to originate from a malfunctioning placental that eventually leads to damage to the maternal endothelium, which in turn gives rise to hypertension and organ dysfunction. LÄS MER
