  1. 1. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

    University dissertation from Lund University, Faculty of Medicine

    Author : Deepak Raina; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; Bone tissue engineering; Bone morphogenic protein-2; Zoledronic acid ZA ; calcium sulphate; Hydroxyapatite; Gelatin;

    Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE

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

    University dissertation from Umeå universitet

    Author : Sven Öberg; Umeå universitet.; [2003]
    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; MEDICINE Surgery; MEDICIN 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.

  3. 3. Human embryonic stem cells for bone engineering applications

    University dissertation from Umeå universitet

    Author : Giuseppe Maria de Peppo; Göteborgs universitet.; Gothenburg University.; [2011]
    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

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

    University dissertation from Göteborg : University of Gothenburg

    Author : Ibrahim Elgali; Göteborgs universitet.; Gothenburg University.; [2015]
    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.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sonya Piskounova; Uppsala universitet.; [2011]
    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
