  1. 16. Experimental Studies on the Vasculature of Endogenous and Transplanted Islets of Langerhans

    Författare :Göran Mattsson; Leif Jansson; Alberto Hayek; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; islets of Langerhans; endothelial cells; islet transplantation; vascular density; diabetes mellitus; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : The blood vessels of the pancreatic islets are of crucial importance for oxygen and metabolite supply as well as dispersal of secreted hormones. In addition to this, endothelial cells have an important role in the revascularization process after islet transplantation. LÄS MER

  3. 17. Engineering the shape of bacterial cellulose and its use as blood vessel replacement

    Författare :Henrik Bäckdahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tissue engineering.; smooth muscle cells; bacterial cellulose; scaffold design; tubular fermentation; biocompatibility evaluation; Blood vessel; vascular graft;

    Sammanfattning : Tissue loss and organ failure are major health problems that impose great costs on society. Cardiovascular diseases are responsible for 36% of mortalities and the disease burden among adults over the age of 60. The single largest cardiovascular disease is atherosclerosis in the coronary artery. LÄS MER

  4. 18. Management of Ischemia and Brain Death-Associated Injuries in Porcine Kidney Grafts

    Författare :Amir Sedigh; Tomas Lorant; Gunnar Tufveson; Olle Korsgren; Styrbjörn Friman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Organs from deceased donors after brain death (BD) remain the major source of organs for transplantation. The catastrophic event of BD and the inevitable consequences of ischemia reperfusion injury (IRI) are linked to impaired graft quality and transplantation outcome. LÄS MER

  5. 19. Extracellular matrix-mediated signaling in the regulation of vascular smooth muscle cell phenotype and function

    Författare :Joy Roy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease is the leading cause of mortality in the world. Even though death rates are today dropping in the developed countries, disability due to the disease is rising worldwide. The major portion of cardiovascular disease associated deaths is due to occlusive atherosclerotic lesions. LÄS MER

  7. 20. Endothelin and angiotensin II receptors in human coronary arteries and bypass grafts - Alterations in cardiovascular disease

    Författare :Angelica Wackenfors; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; vasoconstriction; receptors; cardiovascular disease; human; coronary arteries;

    Sammanfattning : Angiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis, the contractile Ang II and endothelin receptors were examined in endothelium-denuded human coronary arteries and in bypass grafts (the left internal mammary artery and the saphenous vein), with focus on receptor alterations in cardiovascular disease.
