1. 1. Osteogenesis Imperfecta : Genetic and Therapeutic Studies

   Författare :Katarina Lindahl; Östen Ljunggren; Andreas Kindmark; Carl-Johan Rubin; David Sillence; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; OI; BMD; Genotype; Phenotype; Pharmaco-genetics; Bisphosphonate; Therapy; Gene-therapy; Mutation; Collagen; Collagen type I; Allele-specific silencing; siRNA; RNAi; COL1A1; COL1A2; Stroke; C-propeptide; Mineralization; Heterozygous disadvantage; Genetics; Genetik; Medicin; Medicine; Medical Genetics; Medicinsk genetik;

   Sammanfattning : Osteogenesis imperfecta (OI) is a heterogeneous disease of connective tissue, the cardinal symptom being fractures and severity ranging from mild to lethal. Dominant mutations in collagen I, encoded by COL1A1 and COL1A2, cause >90% of cases. LÄS MER

3. 2. Living with osteogenesis imperfecta

   Författare :Veronica Balkefors; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Osteogenesis Imperfecta (OI) is a hereditary connective tissue disorder with fragility of the bones as the dominant symptom. There is no cure for OI, but symptoms are treated with medical, orthopaedic and physiotherapy methods. The disease group is very heterogeneous and knowledge about adults living with the milder forms, type I or IV is limited. LÄS MER

4. 3. The synergistic role of hierarchical macro- and mesoporous implant surface and microscopic view of enhanced osseointegration

   Författare :Guang Han; Zhijian Shen; Anders Palmqvist; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosity; cell adhesion; cell proliferation; surface topography; implant; bone-implant interface; argon ion beam polishing; osteogenesis; osseointegration; Materials Chemistry; materialkemi;

   Sammanfattning : The trend for designing of a titanium implant explored using different chemical compositions and crystallinity materials until people realized that the implant surface character was another important factor affecting the rate and extent of osseointegartion. Titanium received a macroporous titania surface layer by anodization, which contains open pores with average pore diameter around 5μm. LÄS MER

5. 4. Bone Regeneration with Cell-free Injectable Scaffolds

   Författare :Gry Hulsart Billström; Sune Larsson; Kenneth B Jonsson; Jöns Hilborn; Håkan Engqvist; Olle Svensson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone tissue engineering; hydrogel; computed tomography; positron emission tomography; large femoral bone defect; rat model; hydrogel; in vivo; osteogenesis; bone regeneration; 3R; single-photon emission computed tomography; bone morphogenetic protein 2; calcium phosphates; injectable; bisphosphonate;

   Sammanfattning : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Autologous bone grafting is commonly used throughout the world. LÄS MER

7. 5. Bone Enhancement with BMP-2 for Safe Clinical Translation

   Författare :Marta Kisiel; Jöns Hilborn; Monica Wiig; Richard Oreffo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone repair; Bone healing; Bone morhogenetic protein-2; Osteogenesis; Extracelular matrix; Hyaluronan; Animal model; Orthopaedics; Ortopedi; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

   Sammanfattning : Bone morphogenetic protein-2 (BMP-2) is considered a promising adjuvant for the treatment of bone regeneration. However, BMP-2 delivery in a conventional collagen scaffold needs a high dose to achieve an effective outcome. Moreover, such dosage may lead to serious side effects. LÄS MER
