1. Changes in bone mass and skeletal structure in the postmenopausal period
Sammanfattning : The aim of this thesis was to evaluate long-term changes in bone mass and skeletal structure in the forearm in the peri- and postmenopausal period. 156 premenopausal women, at baseline aged 48 years, not taking medications and without disease processes known to interfere with bone metabolism, were followed through menopause by measurements of bone mass and skeletal structure at the cortical site of the distal radius by single photon absorptiometry, on average every second year until age 72.

2. Risk factors for bone fragility and fracture in postmenopausal women
Sammanfattning : The aim of this thesis was to evaluate risk factors for bone fragility and fractures in postmenopausal women in a long-term perspective. The study period spanned from the age of 48 to age 82 and is thus unique in its length. The studied sample was homogeneous and consisted of 390 north European women from a population-based cohort.

3. Human embryonic stem cells for bone engineering applications
Sammanfattning : The human skeleton represents the supporting structure of the organism and accounts for about 20 percent of the total body mass. Despite its intrinsic capacity to regenerate and self-repair, this ability is limited and repair therapies are needed in a large number of clinical cases. LÄS MER
4. Osteocytes as indicators of bone quality - multiscale structure-composition characterisation of the bone-implant interface
Sammanfattning : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. LÄS MER
5. Physical Activity, Bone Mass and Bone Structure in Pre-pubertal Children
Sammanfattning : Low bone mineral density (BMD) is a risk factor for fractures and much of the fracture preventive effort today is devoted to preventing low BMD. Physical activity (PA) has been described as one of the best strategies to optimize skeletal development in the growing child. LÄS MER
