  1. 36. Merging electronics and the brain - towards a fully biocompatible neural interface

    Författare :Gustav Lind; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural interface; neural implants; BMI; tissue reactions; biocompatibility; rat; astrocytes; microglia;

    Sammanfattning : Techniques for interfacing the nervous system using chronically implanted electrodes are turning into invaluable tools for neurophysiological research and treatment of neurological disorders. These methods have been developed and refined over the last decades. LÄS MER

  3. 37. Restoration of scarred vocal folds with stem cell implantation : analyses in a xenograft model

    Författare :Bengt Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Tissue defects in the vocal fold (VF) caused by trauma, surgical procedures, post radiotherapy, often heal with scar formation. The scar tissue causes stiffness of the lamina propria rendering disturbed viscoelastic properties to the VF. A scarred VF causes severe voice problems. LÄS MER

  4. 38. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

    Författare :Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

  5. 39. Clinically Unrecognized Myocardial Scars Detected by MRI

    Författare :Raquel Espregueira Themudo; Tomas Bjerner; Andrew Arai; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unrecognized myocardial scars; myocardial infarction; epidemiology; magnetic resonance; computed topographic coronary angiography; exercise test; NT-proBNP; Radiology; Radiologi; Cardiology; Kardiologi;

    Sammanfattning : A high percentage of unrecognized myocardial infarctions (UMIs) seen at delayed-enhanced magnetic resonance imaging (DE-MRI) are not detected by ECG. DE-MRI-detected UMIs are independent predictors of cardiovascular events in patients with coronary artery disease. LÄS MER

  7. 40. Out of hospital cardiac arrest : with focus on bystander CPR and public access defibrillation

    Författare :Mattias Ringh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Out-of-hospital cardiac arrest (OHCA) annually affecting hundreds of thousands of patients in Europe alone. Survival is highly dependent on time to treatment (cardiopulmonary resuscitation (CPR) and defibrillation). Long emergency medical system (EMS) time intervals and low bystander CPR rates are major obstacles for increased survival. LÄS MER
