  1. 1. Clinical Bedside Studies of Cerebral Blood Flow in Severe Subarachnoid Hemorrhage Using Xenon CT

    Author : Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; delayed cerebral ischemia; cerebral blood flow; HHH-therapy; triple-H; xenon CT; XeCT; cerebral microdialysis; Neurokirurgi; Neurosurgery;

    Abstract : Aneurysmal subarachnoid hemorrhage (SAH) is frequently complicated by delayed cerebral ischemia (DCI), contributing to poor outcome. Particularly for patients in poor neurological state, prediction of the acute clinical course is difficult, as is the early detection of DCI. READ MORE

  2. 2. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

    Author : Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
    Keywords : Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

    Abstract : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. READ MORE

  3. 3. Development and Characterization of a Global Brain Ischemia Model in the Mouse -A Genetic and Pharmacological Approach

    Author : Tomas Olsson; Neuroinflammation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsykologi; Neurologi; neuropsychology; Neurology; global; hypothermia; hsp70; receptor; adenosine A1; NMDA; cystatin C; cell death; hippocampus; Brain; ischemia; neurophysiology;

    Abstract : Brain ischemia is a major cause of death and morbidity in the industrialized countries. It is mainly caused by stroke, but may also be the consequence of successful cardiopulmonary resuscitation in victims of cardiac arrest, known as transient global ischemia. READ MORE

  4. 4. Cerebral Injury in Perinatal Asphyxia, epidemiological, clinical, neurophysiological and neuromatabolic investigations

    Author : Kristina Thorngren-Jerneck; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Neurology; Pediatri; Pediatrics; S100; EEG; CMRgl; cerebral glucose metabolism; FDG-PET; CP; infant; perinatal asphyxia; hypoxia-ischemia;

    Abstract : Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) is the most important cause of perinatal mortality and cerebral palsy (CP) in infants born at term. The aim of the thesis was to investigate epidemiology of perinatal asphyxia, and to investigate early clinical neurological symptoms after perinatal asphyxia in relation to cerebral glucose metabolism (CMRgl) measured by 18-FDG-PET, neurophysiological function, some biochemical markers, also in relation to long-term outcome.

  5. 5. Estrogen-inducible neuropeptides in the rat brain: role in focal ischemic lesions

    Author : Annette Theodorsson; Elvar Theodorsson; A: Langmoen; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Estrogen; neuropeptides; galanin; cerebral ischemia; middle cerebral artery occlusion; Neurochemistry; Neurokemi;

    Abstract : Sex steroids in general and estrogens in particular – in addition to their effects on the reproductive organs – affect a large number of crucial bodily functions, including “higher” brain functions.Neuropeptides constitute the phylogenetically oldest neurotransmitter system and are currently thought to act mainly during stress, disease or injury.
