1. 6. Electrical Bioimpedance Cerebral Monitoring : From Hypothesis and Simulation to First Experimental Evidence in Stroke Patients

   Författare :Seyed Reza Atefi; Fernando Seoane; Michael Bodo; Kaj Lindecrantz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Biompedance Spectroscopy; Stroke; Hemorrhage; Ischemia; FEM; HFSS; Electrical Potentials; Människan i vården;

   Sammanfattning : Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. LÄS MER

3. 7. Observations on cerebral amyloid angiopathy and microvascular pathology in Alzheimer's disease and vascular dementia

   Författare :Mattias Haglund; Tumörmikromiljö; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patologi allmän ; pathological anatomy; General pathology; Vascular dementia; Alzheimer s disease; Cerebral infarction; Locus ceruleus; White matter; Microvasculature; Cerebrovascular disease; patologisk anatomi; Ischemia; Cerebral amyloid angiopathy;

   Sammanfattning : Dementia is a state of permanent loss of cognitive function, most commonly affecting the elderly. With a rapidly growing aged population, the spectrum of disorders that lead to dementia is exerting an ever-increasing toll on patients, families and society alike. The most common dementing disorders are Alzheimer's disease and vascular dementia. LÄS MER

4. 8. Protein Kinase Inhibition in Late Cerebral Ischemia after Subarachnoid Hemorrhage

   Författare :Saema Ansar; Lund Medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; protein kinase; cerebral ischemia; subarachnoid hemorrage; neurofysiologi; neuropsykologi;

   Sammanfattning : The cerebral ischemia that occur after a subarachnoid hemorrhage (SAH) often results in death or severe disability and is a significant cause of stroke. Our hypothesis is that cerebral ischemia leads to pathophysiological receptor changes on the vascular smooth muscle cells. LÄS MER

5. 9. Experimental cardiopulmonary cerebral resuscitation : A study of cerebral perfusion with special reference to the postresuscitation disturbances

   Författare :Ala Nozari; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; cerebral blood flow; post-resuscitation period; epinephrine; vasopressin; aortic occlusion; isoprostane; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

   Sammanfattning : Ischemic neuronal injury continues to be a major delimiting factor in achieving successful clinical outcomesafter resuscitation from cardiac arrest. In this thesis, a pig model of cardiopulmonary resuscitation (CPR) wasused to address the effects of different interventions on cerebral blood flow and oxygenation during CPR and theinitial postresuscitation period.

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

   Författare :Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

   Sammanfattning : 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. LÄS MER
