  1. 11. 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.

    Sammanfattning : BACKGROUND. Various techniques of surgical intervention have been suggested to promote bone densityand volume; however, the predictability of such techniques is not always sufficiently supported by preclinicalevaluations.AIM. LÄS MER

  4. 13. NOTUM and RSPO3 in Bone - WNT signaling modulators regulating the skeleton

    Författare :Karin H. Nilsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NOTUM; RSPO3; WNT signaling; Bone;

    Sammanfattning : Osteoporosis is a skeletal disease affecting millions of people worldwide, often leading to fragility fractures and a decreased quality of life. There is an unmet medical need for new anabolic, bone building, treatments. LÄS MER

  5. 14. Effects of silicon on bone. Clinical observations and experimental cell studies

    Författare :Catarina Magnusson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; silicon; osteoclast; pregnancy; lactation; bone metabolism; bone regeneration;

    Sammanfattning : Bone health has a major impact on life quality. In Sweden, osteoporosis is a highly prevalent skeletal disease that primarily affects the elderly, causing fragility fractures and pain. LÄS MER

  7. 15. On implant integration in irradiated bone : clinical and experimental studies

    Författare :Jan Nyberg; Börje Svensson; Christer Dahlin; Carina B. Johansson; Bo Sunzel; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental implant; osseointegration; radiation therapy; bone remodeling; histomorphometry; hyperbaric oxygen therapy; gene expression and in vivo; Surgery; Kirurgi;

    Sammanfattning : Radiation has an impact on the processes involved in bone- healing, regeneration and remodeling. The mechanisms that cause impaired bone healing of dental implants are not fully understood. Adjunctive treatments to revers radiation effects are limited. LÄS MER
