  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. Cytokines and bone : On the role of IL-1 and IL-6 in bone metabolism

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Eva Bornefalk; Uppsala universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; bone; cytokines; osteoporosis; cAMP; IL-1; IL-6; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : Cytokines such as interleukin-1 (IL-l) and interleukin-6 (IL-6) have been implicated in the pathogenesis of postmenopausal osteoporosis. The regulation of cytokine release is unclear, and the mechanism of cytokine induced bone resorption remains to be elucidated. READ MORE

  4. 4. The Anabolic - Anti-catabolic Paradigm of Augmenting Skeletal Regeneration: A Bone Quality Perspective

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Neashan Mathavan; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2017-05-08]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone fracture; Fracture healing; bone quality; Bone biomechanics; bone morphogenetic protein-7; Zoledronate; skeletal regeneration;

    Abstract : Successful fracture repair is a complex series of coordinated processes leading to regeneration of new bone to bridge the fracture site, remodelling of the newly formed bone and restoration of skeletal function. Disruption of these processes occurs in approximately 10% of all fractures and leads to delayed or failed healing requiring surgical interventions, increased complication rates, prolonged rehabilitation and high morbidity.

  5. 5. Survival of onlay bone grafts. A study in the adult rat

    University dissertation from Department of Oral Surgery and Oral Medicine, Faculty of Odontology, Carl Gustafs väg 34, SE-214 21 Malmö, Sweden

    Author : Monica Gordh; Lunds universitet.; Lund University.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Abstract : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.
