  1. 1. Extreme hemodilution: Effects of inhalation anesthetics, hypoxia, and blood loss. An Experimental study in pigs

    Author : Henning Schou; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; oxygen saturation.; blood volume; coronary circulation; blood lactate; oxygen uptake; Anemia; oxygen delivery; intensive care; Anestesiologi; intensivvård;

    Abstract : Hemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%.

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Fredrik Clausen; Lars Hillered; Tiit Mathiesen; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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;

    Abstract : 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. READ MORE
