  1. 11. Physiological response to exercise in the Icelandic horse

    Författare :Gudrún Stefánsdóttir; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis examined the exercise physiology of the Icelandic horse by: 1) studying physiological response in stallions and mares of different ages performing a true breed evaluation field test (BEFT); 2) comparing the effect of ridden tölt and trot at three speeds on physiological response; 3) evaluating physiological response to a simulated 100 m flying pace race; 4) measuring the effect of increasing body weight ratio (BWR) of rider to horse (20, 25, 30, and 35 %) on physiological response in an standardised incremental field exercise test at tölt at 5.4 m/s; and 5) determining the effect of rider on physiological response.

  2. 12. Cerebral ischemia studied with positron emission tomography and microdialysis

    Författare :Peter Frykholm; Peter Kirkpatrick; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Cerebral ischemia; penumbra; positron emission tomography; microdialysis; middle cerebral artery occlusion; Neurovetenskap; Neurology; Neurologi; Neurosurgery; neurokirurgi;

    Sammanfattning : Stroke is the third leading cause of morbidity and mortality in the industrialized world. Subarachnoid hemorrhage (SAH), the least common form of stroke, is one of the most demanding diseases treated in neurointensive care units. Cerebral ischemia may develop rapidly, and has a major influence on outcome. LÄS MER

  3. 13. A forage-only diet and reduced high intensity training distance in standardbred horses : growth, health and performance

    Författare :Sara Ringmark; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis examined growth, health and performance in sixteen 1.5-3-year-old Standardbred horses fed a forage-only diet and trained to race as 3-year-olds in either a control training programme (C-group) or a training programme in which the high intensity training distance was reduced by 30% (R-group).

  4. 14. On the pathophysiology of idiopathic adult hydrosephalus syndrome : energy metabolism, protein patterns, and intracranial pressure

    Författare :Aina Ågren Wilsson; Per Enblad; Umeå universitet; []
    Nyckelord :hydrocephalus; biochemical markers; microdialysis; cerebrospinal fluid; B waves; brain tissue oxygen tension; Neurology; neurologi;

    Sammanfattning : The symptoms in Idiopathic Adult Hydrocephalus Syndrome (IAHS) – gait disturbance, incontinence, and cognitive deficit – correlate anatomically to neuronal dysfunction in periventricular white matter. The pathophysiology is considered to include a cerebrospinal fluid (CSF) hydrodynamic disturbance, including pressure oscillations (“B waves”), in combination with cerebrovascular disease. LÄS MER

  5. 15. Ventricular fibrillation and defibrillation in patients with implantable cardioverter defibrillators

    Författare :Mikael Runsiö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ventricular fibrillation; defibrilla~ion; implantable cardioverter defibrillator; haemodynamic; metabolism; hyperaemia; ischaemia; myocardial injury; histamine; neuropeptide 1: noradrenaline; endothelin; histamine; positron emission tomography.;

    Sammanfattning : Since the introduction of the implantable cardioverter defibrillator for humans with malignant ventricular arrhythmias in 1980, over 50, 000 patients world wide have received this device. The implantation procedure is simple and resembles the implantation of an ordinary pacemaker. LÄS MER
