  1. 1. Astrocyte metabolism following focal cerebral ischemia

    Författare :Anna E Thoren; Göteborgs universitet; []
    Nyckelord :Astrocyte; metabolism; focal cerebral ischemia; reperfusion; infarct; [1-14C]acetate; [U-14C]glucose; glutamine; glutamate; ATP; ADP; lactate; MCT4; immunogold cytochemistry;

    Sammanfattning : Stroke is one of the leading causes of disability and death. Most often, stroke results from blockage of an artery in the brain leading to tissue infarction within the perfusion territory of the affected vessel. LÄS MER

  2. 2. Mathematical Modelling of Cerebral Metabolism : From Ion Channels to Metabolic Fluxes

    Författare :Nicolas Sundqvist; Gunnar Cedersund; Maria Engström; Roland Nilsson; Sebastian Sten; João Duarte; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The brain is the most metabolically active organ in the human body and therefore rely on a continuous supply of oxygen and glucose. Neuronal stimulation in specific regions of the leads to the firing of action potentials, a process facilitated by voltage-gated ion channels in the neurons’ cell membranes. LÄS MER

  3. 3. Cerebral Perfusion and Metabolism during Experimental Extracorporeal Circulation

    Författare :Ove Jonsson; Stefan Thelin; Fredrik Lennmyr; Sven-Erik Ricksten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral perfusion; Experimental brain research; Experimentell hjärnforskning; Thoraxkirurgi; Thorax Surgery;

    Sammanfattning : Neurologic injuries are major causes of mortality and morbidity after cardiac surgery. This thesis aimed to investigate cerebral metabolism and perfusion abnormalities in pigs during hypothermic circulatory arrest, selective antegrade cerebral perfusion (SACP) and extracorporeal circulation following progressive venous stasis.

  4. 4. Severe cerebral emergency : aspects of treatment and outcome in the intensive care patient

    Författare :Marie Rodling Wahlström; Silvana Naredi; Sven-Erik Gisvold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; severe traumatic brain injury; intracranial pressure-targeted therapy; albumin; prostacyclin; endothelial dysfunction; pro-inflammatory cytokines; subarachnoid haemorrhage; asymmetric dimethylarginine; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anaesthesiology; anestesiologi;

    Sammanfattning : Severe Traumatic Brain Injury (TBI) and aneurysmal Subarachnoid Hemorrhage (SAH) are severe cerebral emergencies. They are common reasons for extensive morbidity and mortality in young people and adults in the western world. LÄS MER

  5. 5. Brain Tissue Oxygenation in Traumatic Brain Injury : Experimental and Clinical Studies

    Författare :Karlis Purins; Anders Lewén; Per Enblad; Oliver Sakowitz; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain tissue oxygenation; Cerebral metabolism; Traumatic brain injury; Cerebral ischemia; Threshold levels; Neurovent-PTO; Microdialysis; Neurosurgery; Neurokirurgi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of death and disability. TBI is frequently followed by cerebral ischemia which is a great contributor to secondary brain damage. The main causes of cerebral ischemia are pathophysiological changes in cerebral blood flow and metabolism. LÄS MER
