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

    Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    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

    Sammanfattning : Capillary-based platforms for diagnostics are popular for the point-of-care diagnostics market because of their low cost, easy fabrication, and easy operation. Lateral flow tests are an excellent example of capillary-based platforms for point-of-care diagnostics. LÄS MER

  4. 3. Pathophysiology of 5-fluorouracil induced cardiotoxicity : a clinical and experimental study

    Författare :Magdalena Cwikiel; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; cell culture.; scanning and transmission electron microscopy; endothelium; lipid peroxidation; free radical; fibrinogen; 5-fluorouracil; blood and plasma viscosity; cardiotoxicity; cancerology; Cytologi; onkologi; cancer; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : This thesis concerns the pathophysiology of 5-fluorouracil (5-FU) induced cardiotoxicity. The aim of the clinical studies was to determine whether hemorheological factors might explain 5-FU cardiotoxicity (I) and if the syndrome was associated with free radical (FR) generation and lipid peroxidation (II).

  5. 4. Blood flow and cell transport in arteries and medical assist devices

    Författare :Niclas Berg; Lisa Prahl Wittberg; Laszlo Fuchs; Mihai Mihaescu; Alessandro Veneziani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodynamics; CFD; Artherosclerosis; Thrombosis; Platelet activation; Hemorheology; Platelet margination; Technology and Health; Teknik och hälsa;

    Sammanfattning : The cardiovascular system is responsible for transport of nutrients, oxygen, as well as the cells and molecules making up the immune system. Through the hemostatic system, the body maintains the integrity of the blood vessels, and prevents bleeding. LÄS MER

  7. 5. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    Författare :Lieselotte Frost-Arner; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. LÄS MER
