  1. 16. Thioredoxin and glutaredoxin systems under oxidative and nitrosative stress

    Författare :Xiaoyuan Ren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Our knowledge about reactive oxygen species (ROS) and reactive nitrogen species (RNS) has been changed from simple damaging molecules to redox signaling mediators. ROS/RNS mediated signaling is mainly based on the reversible post-translational modifications of cysteine which works as a switch for protein functions. LÄS MER

  3. 17. Therapeutic opportunities of alpha-1-microglobulin A study in placenta, blood, skin and eye

    Författare :Martin Cederlund; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reactive oxygen species; hemoglobin; myeloperoxidase; oxidative stress; α1-microglobulin;

    Sammanfattning : This thesis describes functional studies of the human protein alpha-1-microglobulin (A1M), with the aim of exploring its usefulness as a therapeutic agent in diseases where oxidative stress is a prominent feature. A1M is a 26 kDa plasma and tissue protein with reductase activity and radical- and heme-binding antioxidative functions. LÄS MER

  4. 18. Probiotics and berry-associated polyphenols: catabolism and antioxidative effects

    Författare :Maja Jakesevic; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bilberry; Rosehips; Chokeberry; Probiotics; Lactic acid bacteria; Polyphenols; Ischemia-reperfusion; Oxidative stress;

    Sammanfattning : Oxidative stress can cause damage to DNA, proteins and lipids and is associated with inflammation and various human diseases as cancer, atherosclerosis, and autoimmune diseases. Polyphenol-rich diet, such as fruits and berries, may act as antioxidants and prevent oxidative stress and, thereby, associated diseases. LÄS MER

  5. 19. Studies on treatment of renal anemia in patients on chronic hemodialysis

    Författare :Bergur V. Stefánsson; Göteborgs universitet; []
    Nyckelord :hemodialysis; IV iron; oxidative stress; erythropoietin; hepcidin;

    Sammanfattning : In patients with chronic kidney disease, treatment with erythropoiesis-stimulating agents (ESA) effectively corrects anemia. Most of these patients also need supplementation with regular iron injections to secure iron availability for proper erythropoiesis. LÄS MER

  7. 20. Redox processes and oxidative stress in cell and tissue damage

    Författare :Lisa Arodin Selenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxidative stress is described as an imbalance between oxidants and antioxidants, with a shift towards the oxidants. When the antioxidative systems are insufficient or the production of radicals is increased oxidative damage can occur, damaging DNA, lipids, and proteins. Oxidative stress has been implicated in several pathologies. LÄS MER
