1. 16. Risk factors for falls and fractures in elderly women. The Malmö OPRA study

   Författare :Paul Gerdhem; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; muskelsystem; Skelett; muscle system; Skeleton; Falls.; Vitamin D; Bone turnover markers; Frail elderly; Body weight; Physical activity; Osteoporosis; Fractures; Bone density; reumatologi; rheumatology locomotion;

   Sammanfattning : Approximately half of all women will sustain a fracture after the age of 50. Fractures may cause long-term disability and excess mortality. Identifying individuals at high risk of sustaining a fracture is important in the development of primary and secondary prevention strategies. LÄS MER

3. 17. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes

   Författare :Gustav Lindberg; Hållfasthetslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; Osteogenesis; Diffusion in bone; stress enhanced diffusion; Ginzburg-Landau; phase-field; diffusion experiment; Conductivity; Kalman filter; finite element method; Fourier series; Fick’s law; Osteology;

   Sammanfattning : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. LÄS MER

4. 18. Physical activity and the young female skeleton

   Författare :Örnolfur Valdimarsson; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muskelsystem; reumatologi; Skelett; Skeleton; muscle system; rheumatology locomotion; Bone mass; Osteoporosis; Young female skeleton; Physical activity;

   Sammanfattning : The aim of this thesis was to identify the influence of calcium, physical activity and detraining on bone mass and bone size in girls and young women. We hypothesised that calcium intake above a specific level does not enhance the accrual of bone mineral, that exercise predominantly influences the skeleton in the early pubertal period and that reduced training is followed by a loss of exercise-induced skeletal benefits.

5. 19. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

   Författare :Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. LÄS MER

7. 20. Physical activity and its effect on bone in the short- and long- term perspective

   Författare :Christian Lindén; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; fractures; children; exercise; bone size; osteoporosis; Kirurgi; ortopedi; traumatologi; traumatology; aBMD;

   Sammanfattning : Osteoporosis is a growing problem worldwide where Sweden has one of the highest fragility fracture incidences in the world. The growing years are thought to be an opportune time to build strong bones and the enhancement of peak bone mass (PBM) has been suggested as a prevention strategy for osteoporosis. LÄS MER
