  1. 1. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sven-Olof Granstam; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

  2. 2. Mesentric hemodynamics and effects of angiotensin II during circulatory stress

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mats Laesser; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renin-angiontensin system; angiotensin II; intestines; hemodynamics; perfusion; hemorrhage; hypovolemia; endotoxemia;

    Sammanfattning : Mesenteric hypoperfusion and ischemia is considered to be deleterious to the intestinal mucosal barrier function and it is suggested that the renin-angiotensin system plays a pivotal role in the regulation of mesenteric perfusion.The present thesis examines the effects of the specific AT1 receptor blocker candesartan on mesenteric hemodynamics during acute hypovolemia and endotoxinemia.

  3. 3. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

    Detta är en avhandling från Umeå : Umeå University

    Författare :Guilherme Hilgert Elcadi; Högskolan i Gävle.; Högskolan i Gävle.; Umeå universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi; Physiology;

    Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER

  4. 4. Vacuum-Assisted Closure Therapy after Cardiac Surgery. Sternal Stability, Cost of Care, Learning Curve and Hemodynamic Outcome

    Detta är en avhandling från Thoracic Surgery

    Författare :Arash Mokhtari; Lund University.; Lunds universitet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health economics; Vacuum-assisted closure; Sternum; Mediastinitis; Deep sternal wound infection; Cardiac surgery; Wound healing; Hemodynamics; Wound closure;

    Sammanfattning : Deep sternal wound infection (DSWI) following cardiothoracic surgery is a rare but potentially life-threatening complication with high morbidity and mortality. DSWI is associated with a significant increase in the length of hospital stay and the cost of hospitalization. The socioeconomic impact of DSWI is considerable. LÄS MER

  5. 5. Cerebral Hemodynamics through Intracrnial Pressure

    Detta är en avhandling från Thoracic Surgery

    Författare :Sima Shahsavari; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intracranial dynamics; Baroreceptor reflex; Secondary brain injury; Traumatic brain injury; Collapsible tubes; Intracranial pressure; Cushing reflex; Pulse wave propagation; Cerebral autoregulation; Cerebral compliance; Mathematical modelling;

    Sammanfattning : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainly focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. LÄS MER
