  1. 6. Studies of Innate and Adaptive Immunity in Islet Transplantation

    Författare :Maria Hårdstedt; Olle Korsgren; Bo Nilsson; Thierry Berney; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; islet transplantation; islets of Langerhans; xenotransplantation; nonhuman primate; blood; whole blood model; innate immunity; adaptive immunity; IBMIR; chemokines;

    Sammanfattning : Clinical islet transplantation is today an established alternative treatment for a selected group of type 1 diabetes patients. The predominant technique for transplantation is infusion of islets in the liver via the portal vein. LÄS MER

  3. 7. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes

    Författare :Cecilia Eriksson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; TiO2; surface roughness; oxide thickness; wettability; whole blood; inflammation; wound healing; platelets; PMN granulocytes; adhesion; activation; receptor expression; respiratory burst.;

    Sammanfattning : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.

  4. 8. Effect of Surface Nanotopography on Blood-Biomaterial Interactions

    Författare :Natalia Ferraz; Marjam Ott; Jaan Hong; Jan Carlsson; Tom Eirik Mollnes; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoporous alumina; nanotopography; biomaterial; platelets; complement system; macrophages; whole blood; inflammatory response; Chemistry; Kemi; Immunobiology; Immunbiologi; Immunologi; Immunology; Materialvetenskap; Materials Science;

    Sammanfattning : Biologically inspired materials are being developed with the aim of improving the integration of medical implants and minimizing non-desirable host reactions. A promising strategy is the design of topographically patterned surfaces that resemble those found in the extracellular environment. LÄS MER

  5. 9. Organofluorine Mass Balance and Per- and Polyfluoroalkyl Substance Analysis of Environmental Samples and Human Blood

    Författare :Rudolf Aro; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Christopher Higgins; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organofluorine mass balance; PFAS; extractable organofluorine; unidentified organofluorine; whole blood; surface water; effluent; sludge;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) have been linked to a range of negative health and environmental effects. Regulations limiting and/or banning the use of some of the legacy compounds have been introduced. Consequently, the production and use of PFAS has diversified. LÄS MER

  7. 10. The role of platelets in whole blood coagulation

    Författare :Sofia Ramström; Nils Olav Solum; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The body's first line of defence against bleeding is the platelets, small cell fragments with multiple roles in the coagulation process. The platelets are patrolling our blood vessels, looking for damage in the endothelial cell layer, to which they attach and transform, recruit more platelets and assemble the plasma coagulation proteases on their surfaces.
