  1. 16. Effects of Interleukin-4 and Interleukin-13 on Bone

    Författare :Carl-Johan Silfverswärd; Olle Nilsson; Östen Ljunggren; Kenneth Jonsson; Li Felländer-Tsai; Uppsala universitet; []
    Nyckelord :Medicine; Bone; Osteoblasts; Interleukin-4; Interleukin-13; Knockout; Medicin;

    Sammanfattning : Cytokines play important roles in bone metabolism, participating in the complex interplay necessary for normal bone formation and turnover. The aim of the present thesis was to investigate the effects of two anti-inflammatory cytokines, interleukin-4 (IL-4) and interleukin-13 (IL-13) on bone. LÄS MER

  3. 17. Methods for evaluation of early bone healing at titanium implants

    Författare :Karin Hederstierna; Göteborgs universitet; []
    Nyckelord :TOF-SIMS; titanium; porosity; Magnesium; hydroxyapatite; implant surface; bone resorption; bone formation;

    Sammanfattning : Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events in implant healing. The primary aim in this thesis was to develop methods for evaluating bone healing around implants. LÄS MER

  4. 18. Long-term effects of growth hormone replacement therapy in growth hormone deficient adults

    Författare :Galina Götherström; Göteborgs universitet; []
    Nyckelord :growth hormone; body composition; bone mass; bone density; muscle strength; lipids; glucose metabolism; adult onset GHD; childhood onset GHD; gender;

    Sammanfattning : Deficiency of growth hormone (GHD) in adults results in abnormal body composition, reduced bone mass and muscle strength, deteriorated cardiovascular risk factors. Short-term GH replacement reverses many of the symptoms associated with adult GHD. LÄS MER

  5. 19. Injectable Biomaterials for Spinal Applications

    Författare :Alejandro López; Cecilia Persson; Håkan Engqvist; Andreas Boger; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; injectable; biomaterials; bone cement; vertebral compression fractures; spine; radiopacity; minimally invasive treatment; low-modulus cement; oligomer; PMMA; calcium phosphate; vertebroplasty; bone; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The use of injectable biomaterials is growing as the demands for minimally invasive procedures, and more easily applicable implants become higher, but their availability is still limited due to the difficulties associated to their design.Each year, more than 700,000 vertebral compression fractures (VCF’s) are reported in the US and 500,000 VCF’s in Europe due to primary osteoporosis only.

  7. 20. Effect of Physical Activity on Bone, Muscle and Fracture Risk during Growth

    Författare :Bjarne Löfgren; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BMC; bone size; children; exercise; fracture; growth; hip stucture analysis; muscle strength; physical activity;

    Sammanfattning : Osteoporosis and related fractures are a global health problem. Physical activity, especially during growth, has been suggested as a strategy to improve musculoskeletal health in the population. LÄS MER
