  1. 1. 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

  3. 2. Insulin-coated titanium implants - a potential therapy for local bone regeneration

    Författare :Behnosh Öhrnell Malekzadeh; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin; Titanium; Bone; Implant; Osteoblast; Immobilisation;

    Sammanfattning : Background: Insulin is a hormone that regulates glucose metabolism, however, it is also important for bone formation. The anabolic effect of insulin on bone could open up alternative therapies when it comes to local bone regeneration. However, this requires a method for local administration of insulin. LÄS MER

  4. 3. Body composition and bone density in children and adolescents. Relation to growth hormone

    Författare :Hans Fors; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; leptin; body composition; bone mineralisation; DXA; BIA; BIS;

    Sammanfattning : The regulation of growth, body composition and bone mineralisation during childhood and adolescence is a complex and multifactorial process. Growth hormone (GH) is essential for normal growth; in addition, it influences bone mineralisation and body composition in both children and adults. LÄS MER

  5. 4. Bone structure characterisation using neutron scattering techniques

    Författare :Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

    Sammanfattning : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.

  7. 5. Studies on nutrition, body composition and bone mineralization in healthy 8-yr-olds in an urban Swedish community

    Författare :Susanne Eriksson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body composition; bone mineralization; dual energy x-ray absorptiometry; healthy; lipids; metabolic markers; overweight; physical activity;

    Sammanfattning : Background: The incidence of welfare diseases including overweight in childhood is increasing worldwide. The results from a study of healthy pre-school children showed that in a population with well educated parents 17% of the children were overweight or obese at the age of 4 years. LÄS MER
