  1. 6. 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

  3. 7. Computational modelling of blood flow in medical assist devices

    Författare :Francesco Fiusco; Lisa Prahl Wittberg; Lars Mikael Broman; Anders Dahlkild; David Ku; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational fluid dynamics; haemodynamics; platelet activation; thrombogenicity; haemolysis; extracorporeal membrane oxygenation; sensitivity; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Extracorporeal membrane oxygenation (ECMO) is a life-saving support treat-ment in case of pulmonary and/or cardiac failure. An artificial extracorporealcircuit is used to offload the function of lungs and/or heart. LÄS MER

  4. 8. Mechanisms of transendothelial and tissue transport in the peritoneum. Experimental studies on rat

    Författare :Bert-Inge Rosengren; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nefrologi; Urologi; hyaluronan; interstitium; blood flow; rat; pore; inhibition; temperature; peritoneal dialysis; permeability; capillary; protein; passive; active; transport; transcytosis; vesicle; Urology; nephrology; small solute;

    Sammanfattning : In the present thesis, the quantitative role of active transport (transcytosis) in bulk transvascular protein movement in vivo was evaluated. Using chemical transcytosis inhibition (N-ethylmaleimide (NEM) and filipin), we were able to show that NEM actually increases endothelial permeability to macromolecules, probably as a result of unspecific toxic action on endothelial cells.

  5. 9. 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).

  7. 10. 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
