  1. 1. The Role of Kidney Oxygen Homeostasis for the Development of Kidney Disease

    Författare :Carla Carvalho; Fredrik Palm; Peter Hansell; Malou Friederich; Jenny Nyström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxygen; Kidney mitochondria; Hypoxia-inducible factors; Prolyl hydroxylase; von Hippel-Lindau; Diabetes; Aging; Kidney; Sodium; RAAS; Fysiologi; Physiology;

    Sammanfattning : The relation between oxygen supply and demand determines tissue oxygen tension (PO2). When intrarenal tissue PO2 decreases, any compensatory increase in oxygen supply via increased renal blood flow is likely to increase glomerular filtration rate. LÄS MER

  3. 2. To metal, or not to metal : Diverse mechanisms of O2-activation and radical storage in the ferritin superfamily

    Författare :Vivek Srinivas; Martin Högbom; Brian Hoffman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metalloprotein; di-metal; Oxygen activation; Substrate oxidation; Ribonucleotide reductase; Radical; DOPA; ADE-DOT; X-Ray free-electron laser; soluble Methane monooxygenase; Biochemistry; biokemi;

    Sammanfattning : Proteins in the Ferritin-like superfamily are characterized by a four alpha-helical structural motif. These proteins are distributed across all three kingdoms of life and perform a wide range of functions. LÄS MER

  4. 3. Hyperbaric oxygen. Effects on ischemia-reperfusion

    Författare :Johan Tjärnström; Göteborgs universitet; []
    Nyckelord :fibrinolysis; f-MLP; human; hyperbaric oxygen; neutrophils; normobaric; PAI-1; PMA; rat; t-PA; trauma; uPA;

    Sammanfattning : Treatment with hyperbaric oxygen (HBO2) is controversial when treating other disorders than decompression sickness. However, HBO2 is a treatment modality that has gained recognition in certain ischemia-reperfusion situations. LÄS MER

  5. 4. Oxygen-reducing enzymes in coatings and films for active packaging

    Författare :Kristin Johansson; Lars Järnström; Caisa Johansson; Leif J. Jönsson; Jose M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active packaging; food packaging; oxygen scavengers; oxygen-reducing enzymes; dispersion coating; biopolymers; Chemical Engineering; Kemiteknik;

    Sammanfattning : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. LÄS MER

  7. 5. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species

    Författare :Fredrik Clausen; Lars Hillered; Tiit Mathiesen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic Brain Injury; Reactive oxygen species; Fluid percussion injury; Controlled cortical impact; weight drop injury; Extracellular-signal regulated kinase; apoptosis; free radical scavenging; morphology; functional outcome; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. LÄS MER
