  1. 1. Regulation of Microvascular Blood Flow : a clinical and experimental study based on laser Doppler perfusion imaging

    Författare :Helena Golster; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Local blood flow reflexes in the foot skin of healthy controls and in young diabetic patients with or without nerve dysfunction have been studied using laser Doppler perfusion imaging (LDPI). A neurophysiological follow-up study on nerve dysfunction is presented as a complerhent to the work on blood flow regulation in the young diabetics. LÄS MER

  3. 2. Adipose tissue as an active organ : blood flow regulation and tissue-specific glucocorticoid metabolism

    Författare :Jonas Andersson; Tommy Olsson; Stefan Söderberg; Sverker Jern; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11β-hydroxysteroid dehydrogenase type 1; adipose tissue; autonomic nervous system; blood flow; cortisol; nitric oxide; weight loss.; medicin; Medicine;

    Sammanfattning : Background: Despite advances in the treatment of atherosclerosis, cardiovascular disease is the leading cause of death worldwide. With the population getting older and more obese, the burden of cardiovascular disease may further increase. LÄS MER

  4. 3. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury

    Författare :Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; adrenaline;

    Sammanfattning : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. LÄS MER

  7. 5. Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation

    Författare :Ulrika Bitzén; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; acute lung injury; lung mechanics; acute respiratory distress syndrome; intensivvård; Anestesiologi; intensive care; Anaesthesiology; Andningsorganen; Respiratory system; Fysiologi; Physiology; flow regulation; method; lung resistance; compliance; aging;

    Sammanfattning : Knowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure interval.
