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

    Author : Karlis Purins; Anders Lewén; Per Enblad; Oliver Sakowitz; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 17. Importance of MAPK and PKC in cerebrovascular endothelin receptor changes

    Author : Marie Henriksson; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; farmakognosi; farmaci; toxikologi; toxicology; pharmacy; pharmacognosy; Pharmacological sciences; Kardiovaskulära systemet; Cardiovascular system; Fysiologi; Physiology; cerebral arteries; ischemia; receptors; endothelin; Farmakologi;

    Abstract : Endothelin is a vasoactive peptide that exerts its effect through two receptors; the endothelin type A (ETA) and type B (ETB) receptor. The contractile ETA receptor is localized on smooth muscle cells in the vascular wall, while the ETB receptors are mainly situated on endothelial cells, mediating vasodilatation. READ MORE

  5. 18. Signal Transduction and Gene Regulation in Cerebral Arteries Following Ischemia

    Author : Petter Vikman; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Cardiovascular system; stroke; molecular investigation; gene expression; Mitogen Activated Protein Kinases; Natural science; Kardiovaskulära systemet; cerebral arteries;

    Abstract : The thesis consideres the molecular events that take place in the cerebral arteries following a stroke. The degree and temporal course of reperfusion following a stroke is pivotal for the survival of the neuronal tissue in the penumbra. READ MORE

  6. 19. Mechanisms of Mitochondria-Induced Brain Damage Following Ischemia and Hypoglycemia

    Author : Michel Ferrand-Drake; Lund Wallenberg Neurocentrum; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cyclosporin A; neuronal death; calpain; caspase; mitochondrial permeability transition; necrosis; apoptosis; cerebral ischemia; hypoglycemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : Mechanisms of Mitochondria-Induced Brain Damage Following Ischemia and Hypoglycemia Following prolonged disruption of blood flow to the central nervous system (CNS), or energy deprivation by other means, such as hypoglycemia, some cells will inevitably degenerate. It has been, and still is, the subject of considerable debate and intense research on brain ischemia, as to the mode of cell death, i. READ MORE

  7. 20. Neurointensive care of subarachnoid hemorrhage : Clinical and neurochemical aspects

    Author : Kristina Giuliana Cesarini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; SAH; neurointensive care; neurochemical monitoring; cerebral ischemia; microdialysis; cerebral metabolism; secondary ischemic events; clinical outcome; Neurovetenskap; Neurology; Neurologi; Neurosurgery; neurokirurgi;

    Abstract : Neurointensive care (NIC) has gained terrain in the treatment of patients with various acute cerebral conditions. It is based on the concept that an unfavorable clinical outcome, to a certain extent, results from all secondary ischemic insults sustained by the brain during the acute phase of the disease.
