1. 11. Energy metabolism in skeletal muscle during ischemia and reperfusion. Experimental and clinical aspects

   Författare :Jonas Lundberg; Göteborgs universitet; []
   Nyckelord :energy metabolism; skeletal muscle; ischemia; reperfusion; MRS; hypothermia; singlet oxygen energy.;

   Sammanfattning : Microsurgical operations, using free vascularised transfer of tissues, induce an obligatory period of ischemia followed by reperfusion. The degree of ischemia and reperfusion injury is dependent on the ischemia time. LÄS MER

3. 12. Changes in gene expression during delayed neuronal death after cerebral ischemia in the rat

   Författare :Fredrik Kamme; Lund Wallenberg Neurocentrum; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; ischemia; brain; neuronal death; gene expression; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : After transient global cerebral ischemia, selected populations of neurons in the brain will die after a period of 2-3 days, a phenomenon termed delayed neuronal death. This is of clinical importance as delayed neuronal death has been found to occur in humans as well. LÄS MER

4. 13. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

   Författare :David G Strauss; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

   Sammanfattning : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

5. 14. Renal Ischemia/Reperfusion Injury in Diabetes : Experimental Studies in the Rat

   Författare :Jan Melin; Bengt Rippe; Uppsala universitet; []
   Nyckelord :Medical sciences; diabetes mellitus; ischemia reperfusion; rat; end-stage renal disease; inflammation; fibrosis; hyaluronan; CD44; treatment; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Sammanfattning : Diabetes mellitus (DM) is one of the leading causes of end stage renal failure. An increased susceptibility to renal ischemia/reperfusion (I/R)-injury was found in DM rats. Unilateral renal ischemia for as short as 20 minutes led to an irreversible progressive injury in DM kidneys, whereas the injury in non-DM kidneys was almost reversible. LÄS MER

7. 15. Energy-Related Metabolites during and after Induced Myocardial Ischemia and Retroperfusion of the Coronary Sinus : An Experimental Study in the Pig with the Microdialysis Technique and Extracorporeal Circulation

   Författare :Vitas Zemgulis; Rolf Ekroth; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischemia; myocardial infarction; reperfusion; energy metabolism; coronary sinus retroperfusion; microdialysis; taurine; nucleoside transport; adenosine; aerobic lactate production; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Sammanfattning : In the clinical setting great efforts have been made with contradictory results to operate upon acutely myocardial ischemic patients. The reasons for the absence of unambiguous results are not well understood nor are they scientifically explored. LÄS MER
