  1. 1. The role of reactive oxygen species in traumatic brain injury : Experimental studies in the rat

    Författare :Niklas Marklund; Uppsala universitet; []
    Nyckelord :Medical sciences; Apoptosis; CBF; controlled cortical contusion injury; 3; 4-dihydroxybenzoate; fluid percussion injury; glucose; 4-hydroxybenzoate; microdialysis; Morris Water Maze; neuroprotection; nitrones; PBN; rat; reactive oxygen species ROS ; salicylate; S-PBN; TBI; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Neurosurgery; neurokirurgi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of mortality and disability. As common sequelae in survivors of TBI are disabling functional, emotional and cognitive disturbances, improved treatment of TBI patients is urgently needed. At present, no neuroprotective pharmacological treatment exists. LÄS MER

  2. 2. Experimental cardiopulmonary cerebral resuscitation : with special reference to cerebral eicosanoid production and free radical scavengers

    Författare :Xiaoli Liu; Marianne Forsman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; cerebral resuscitation; reperfusion damage; oxidative injury; eicosanoid; free radical scavenger; neurological function; alkaline buffer; S-PBN; PBN; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi; Anaesthesiology;

    Sammanfattning : Reperfusion injury after restoration of spontaneous circulation (ROSC) is often considered one of the predominant factors in determining neurological outcome in cardiac arrest. Therefore one of the main targets of experimental and clinical studies has been to mitigate this reperfusion injury. LÄS MER

  3. 3. Mechanisms of Brain Damage Following Focal Cerebral Ischemia: Changes in Ion Homeostasis and the Importance of Free Radical Formation

    Författare :Gunilla Gidö; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PBN; free radicals; potassium; extracellular calcium; neuronal damage; energy-depletion; hypoglycemia; Cerebral focal ischemia; spreading depression; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : In this thesis mechanisms of neuronal damage were investigated in an experimental stroke model i.e focal ischemia. The influence of SD-induced calcium transients on neuronal damage were studied in animals with reduced energy supply. LÄS MER

  4. 4. Survival of Cultured and Grafted Embryonic Dopaminergic Neurones - Effects of hypothermia and prevention of oxidative stress

    Författare :Jenny Karlsson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; 6-OHDA; lazaroid; PBN; brain; transplant; Parkinson s disease; dopamine; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Transplantation of embryonic dopaminergic neurones can ameliorate symptoms in Parkinson’s disease, but a major obstacle for clinical transplantations to overcome is the low survival (typically 5-10%) of implanted nigral neurones. If cell death in nigral grafts can be prevented, less embryonic tissue would be needed per transplantation session and hence more patients could receive intracerebral grafts as a therapy for Parkinson’s disease.

  5. 5. Novel Interventions in Cardiac Arrest : Targeted Temperature Management, Methylene Blue, S-PBN, Amiodarone, Milrinone and Esmolol,  Endothelin and Nitric Oxide In Porcine Resuscitation Models

    Författare :Frank Zoerner; Fredrik Lennmyr; Cécile Martijn; Lars Wiklund; Sven Erik Gisvold; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; restoration of spontaneous circulation; ROSC; cardiopulmonary resuscitation; CPR; cardiac arrest; methylene blue; MB; S-PBN; mild therapeutic hypothermia; MTH; targeted temperature management; TTM; endothelin; ET-1; ECE-1; ETAR; ETBR; nitric oxide; NO; nitric oxide synthase; NOS; eNOS; iNOS; nNOS; porcine; amiodarone; hypovolemia; milrinone; vasopressin; esmolol; epinephrine; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care; Medical Cell Biology; Medicinsk cellbiologi; Cardiology; Kardiologi;

    Sammanfattning : It is a major clinical problem that survival rates after out-of-hospital cardiac arrest have not markedly improved during the last decades, despite extensive research and the introduction of new interventions. However, recent studies have demonstrated promising treatments such as targeted temperature management (TTM) and methylene blue (MB). LÄS MER
