  2. 11. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Author : Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Abstract : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

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

    Author : Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 13. Acoustofluidic preparation of whole blood components

    Author : Anke Urbansky; NanoLund: Centre for Nanoscience; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; acoustophoresis; ultrasound; microfluidics; cell separation; blood; blood fractionation;

    Abstract : Whole blood is rich in information about the physical state of an individual and is routinely used in a variety of clinical and research applications. In this thesis, the use of a microfluidic technique called acoustophoresis for separation of different blood components is explored. READ MORE

  6. 14. Proteomic, metabolomic, and microbiome studies of blood pressure

    Author : Yi-Ting Lin; Johan Sundström; Martin Magnusson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; hypertension; proteomics; metabolomics; microbiome; molecular epidemiology; Mendelian randomization;

    Abstract : Hypertension is a major risk factor for cardiovascular disease and premature death with a substantial global economic burden. To prevent and treat hypertension, it is crucial to improve our understanding of the pathophysiological mechanisms. Hypertension is a multifactorial condition influenced both by genetic and environmental factors. READ MORE

  7. 15. Myocardial Topical Negative Pressure

    Author : Sandra Lindstedt Ingemansson; Thoraxkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary blood flow; microvascular blood flow; topical negative pressure TNP ;

    Abstract : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. READ MORE
