  1. 1. Testicular blood flow methodological and functional studies in the rat

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jan-Erik Damber; Umeå universitet.; [1978]

    Sammanfattning : Different methods of measuring testicular blood flow in the rat were compared in an attempt to find an accurate method for measuring physiological testicular blood flow. It was found that both the Xenon- 133 clearance technique and the radioactive microsphere technique probably reflect true physiological blood flow in the testis. LÄS MER

  2. 2. Clinical applications of acoustophoresis in blood based diagnostics

    Detta är en avhandling från Department of Biomedical Engineering, Lund university

    Författare :Klara Petersson; [2018-02-20]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Acoustofluidics; Ultrasound; Microfluidics; Blood; Blood Separation; Blood plasma; Lab-on-a-chip; Point-of-care; Blood diagnostics;

    Sammanfattning : In this thesis, acoustofluidics has been used to process blood samples as a sample preparation step prior to biomarker detection. This is often required as the large amount of blood cells otherwise can interfere with the detection method. Acoustofluidics means moving particles or cells with acoustic forces within microfluidic channels. LÄS MER

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

    Detta är en avhandling från Stockholm : Karolinska Institutet

    Författare :Torbjörn Vedung; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    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

  4. 4. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Stevin van Wyk; KTH.; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

  5. 5. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lin Wang; Uppsala universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.
