  1. 11. Osteotomy for gonarthrosis - with special reference to the tibial callus distraction technique

    Författare :Göran Magyar; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiostereometry; radiography; arthroplasty; complications; coating; hydroxyapatite; external fixator; femoral osteotomy; hemicallotasis; Knee osteoarthritis; tibial osteotomy; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Osteotomy is used for correction of the altered load on the gonarthrotic knee joint. It can be performed above or below the knee. Clinical results depend on the correction after bone healing. LÄS MER

  3. 12. Recombinant amelogenin - Strategies for purification and protein processing

    Författare :Johan Svensson Bonde; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Recombinant amelogenin; protein purification; fusion protein; purification tag; enamel; hydroxyapatite; matrix protein; dental regeneration; wound healing; bone formation;

    Sammanfattning : Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. LÄS MER

  4. 13. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering

    Författare :Kristoffer Bergman; Tim Bowden; Jöns Hilborn; Jeffrey Hubbell; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Hydrogel; Tissue Engineering; Scaffold; Minimally invasive strategy; Bone morphogenetic protein; Hydroxyapatite; Bone; Cartilage; Tendon; Polymer chemistry; Polymerkemi;

    Sammanfattning : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. LÄS MER

  5. 14. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

    Författare :Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

    Sammanfattning : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. LÄS MER

  7. 15. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems

    Författare :Cecilia Hahn Berg; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; trypsin; SDS elutability; statherin; salivary proteins; salivary pellicle; proline-rich proteins; plaque control; mucins; microbial adhesion; lubrication; krillase; intraoral friction; hydroxyapatite; gelatin; exchange; enzymes; ellipsometry; dental plaque; degradation; colloidal probe; calcium-induced precipitation; adsorption; atomic force microscopy; total internal reflectance fluorescence spectroscopy;

    Sammanfattning : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. LÄS MER
