  2. 1. Bone Healing after implantation of bone substitute materials. Experimental studies in estrogen deficiency

    Author : Sven Öberg; Jan Rosenquist; Ulf Lekholm; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bone grafts; hydroxyapatite; estrogen deficiency; demineralised bone; bone formation; AAA bone; bone defect; titanium implants; resonance frequency analysis.; Kirurgi; Surgery; Kirurgi; kirurgi; Surgery;

    Abstract : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

  4. 2. Human embryonic stem cells for bone engineering applications

    Author : Giuseppe Maria de Peppo; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

    Abstract : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. READ MORE

  5. 3. Molecular and structural patterns of guided bone regeneration (GBR). Experimental studies on the role of GBR membrane and bone substitute materials

    Author : Ibrahim Elgali; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; biomaterials; bone substitute; calcium phosphate; guided bone regeneration; membrane; strontium; bone defect; bone remodeling; inflammation; cytokines; chemokines; growth factors; gene expression; histomorphometry; in vivo;

    Abstract : The mechanisms of guided bone regeneration (GBR) and bone healing with calcium phosphate (CaP) bone substitutes are not fully understood. The major aim of this thesis was to determine the relationship between the bone formation in bone defects and the cellular distribution and activities in association with CaP materials and/or with GBR membrane.

  6. 4. Altered body composition in adults with complex congenital heart disease

    Author : Karna Johansson; Camilla Sandberg; Bengt Johansson; Thomas Mooe; Mats Börjesson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adults with complex congenital heart disease; ACHD; body composition; skeletal muscle; lean mass; muscular strength; sarcopenia; bone; bone mass; bone mineral density; bone health; osteoporosis; fat; fat mass; obesity; Vuxna med medfödda hjärtfel; vuxna med komplexa medfödda hjärtfel; komplexa medfödda hjärtfel; kroppssammansättning; skelettmuskel; styrka; sarkopeni; ben; benmassa; bendensitet; osteoporos; fett; fettmassa; obesitas; kardiologi; Cardiology;

    Abstract : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. READ MORE

  7. 5. Biomaterials for Promoting Self-Healing of Bone Tissue

    Author : Sonya Piskounova; Jöns Hilborn; Tim Bowden; Simon Cool; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Osseointegration; implant coating; hyaluronan hydrogel; bone morphogenetic protein-2; hydroxyapatite; bone; delivery system; injectable; mixing; radioactive labeling; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Abstract : The present work addresses poor bone/implant integration and severe bone defects. In both conditions external stimuli is required for new bone to form. READ MORE
