  1. 1. On tissue reactions to dentin as a bone substitute material

    Författare :Payam Farzad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grafted dentin; tissue reaction; bone blocks; dental implants; experimental study;

    Sammanfattning : Background Reconstruction of the jaws due to resorption of the alveolar crest may require bone augmentation prior to installation of endosseous implants. Active research on new bone graft materials with bone regeneration ability equivalent to autogenous bone but without the limitations of allogenic, xenogenic and synthetic bone are constantly ongoing.

  3. 2. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration

    Författare :Heithem Ben Amara; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue; Biodegradable implants; Bone–implant interface; Bone marrow; Inflammation; Cellular mechanotransduction; Gene expression; Immunohistochemistry; Magnesium; Neovascularization; Osseointegration; Soft tissue injuries;

    Sammanfattning : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

  4. 3. degradable electroactive polymers: Synthesis, Macromolecular architecture and scaffold design

    Författare :Baolin Guo; Ann-Christine Albertsson; Patric Jannasch; KTH; []
    Nyckelord :Poly lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; phenyl amino-capped aniline tetramer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; chitosan; hydrogel; block copolymer; functionalization; oxidative coupling reaction; self-assembly; toxicity; tubular porous scaffold; neural tissue engineering.;

    Sammanfattning : Electrically conducting polymers induce specific cellular responses at the molecular level. One of the crucial limitations of the use of conducting polymers in tissue engineering is their inability to degrade. LÄS MER

  5. 4. Synthesis, characterization and molecular architecture of electroactive and degradable polymers

    Författare :Baolin Guo; Ann-Christine Albertsson; Anna Finne Wistrand; Ann Cornell; Mark Rutland; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poly L; L-lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; tissue engineering; Polymer chemistry; Polymerkemi;

    Sammanfattning : The third-generation biomaterials are designed to stimulate specific cellular responses at the molecular level. Recent studies have shown that electrical signals regulate cellular activities including cell adhesion, migration, proliferation and differentiation. LÄS MER

  7. 5. Mechanisms and Therapeutic Interventions of Instant Blood-Mediated Inflammatory Reaction (IBMIR)

    Författare :Helena Johansson; Bo Nilsson; Olle Korsgren; Kristina Nilsson-Ekdahl; Tomas Lindahl; Uppsala universitet; []
    Nyckelord :Immunology; Diabetes; Islet transplantation; Islets of Langerhans; Coagulation activation; Complement activation; IBMIR; Tissue factor; Low molecular weight dextran sulfate; Immunologi;

    Sammanfattning : Intraportal transplantation of isolated islets of Langerhans is a procedure approaching clinical acceptance as a treatment for patients with type I diabetes mellitus. One major problem with this treatment is that large amounts of cells are lost at the time of infusion into the portal vein, resulting in a low level of engraftment of the islets. LÄS MER
