  1. 6. Formation of Composite Islet Grafts : A novel strategy to promote islet survival and revascularization

    Författare :Ulrika Johansson; Peetra Magnusson; Korsgren Olle; Bo Nilsson; Federico Bertuzzi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet of Langerhans; cytokines and cytokinereceptors expression; endothelial cells; mesenchymal stromal cells; transplantation; revascularization; Clinical immunology; Klinisk immunologi; cellforskning; cellforskning;

    Sammanfattning : The islets of Langerhans are small and delicate spheroid organs scattered in the pancreas responsible for insulin production. Transplantation of isolated islets is a beneficial therapy for patients with a severe form of type 1 diabetes. LÄS MER

  3. 7. 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

  4. 8. Cytomegalovirus infection in vascular diseases and transplant rejection

    Författare :Mensur Dzabic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human cytomegalovirus (HCMV) infects 60-100% of the adult population. It belongs to the Herpesviridae family and establishes latency within its host post primary infection. HCMV reactivation is dependent on inflammation and the virus has evolved numerous mechanisms to sustain an inflammatory process and thus prolong its replication period. LÄS MER

  5. 9. Vascular repair mechanisms : experimental, physiological and clinical studies

    Författare :Anton Razuvajev; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiovascular disease is the leading cause of global mortality and physical disability mainly due to the complications of atherothrombosis such as myocardial infarction or stroke. Surgical treatment directed to prevent this conditions is limited by the extensive healing response, intimal hyperplasia. LÄS MER

  7. 10. Inducible nitric oxide synthase : in vascular smooth muscle cells

    Författare :Zhong-qun Yan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :nitric oxide; nitric oxide synthase; vascular smooth muscle cells; transcriptional regulation; NF-[kappa]B; I[kappa]B; pathophysiological role;

    Sammanfattning : Besides the constitutively expressed nitric oxide synthase (NOS) in endothelial cells, vascular smooth muscle cells (SMC) have the potential to express the inducible isoform of NOS (iNOS). Given the important effects of nitric oxide and the high output of this enzyme, expression of iNOS in SMC and its pathophysiological significance were investigated in the present study. LÄS MER
