1. 1. Bone and Aluminium

   Författare :Hans-Olov Hellström; Karl Michaëlsson; Hans Mallmin; Olle Svensson; Uppsala universitet; []
   Nyckelord :Surgery; Aluminium; Osteoporosis; Hip fracture; Osteoporotic fracture; Alzheimer´s dementia; Bone mineral density; Bone mineral content; Mortality risk; Biomechanics; Inductively coupled mass spectrometry; Kirurgi;

   Sammanfattning : Osteoporosis is a major health care problem, by reason of its devastating consequences, in particular hip fractures. Worldwide it has been estimated that the incidence of hip fracture will increase to more than 6 million per year by 2050 compared to 1.7 million per year in 1990. LÄS MER

   Sammanfattning : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

4. 3. Risk factors for bone fragility and fracture in postmenopausal women

   Författare :Ola Svejme; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone Fragility; Fracture; Osteoporosis; Bone Mineral Density BMD ; Menopause; Physical activity; Bone Strength; Bone Size; Bone Densitometry;

   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.

5. 4. Bone alkaline phosphatase isoforms in chronic kidney disease : mineral and bone disorder

   Författare :Mathias Haarhaus; Per Magnusson; Anders Fernström; Bengt Lindholm; Goce Spasovski; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Chronic kidney disease (CKD) is associated with increased mortality and cardiovascular complications. Disturbances in mineral metabolism occur early In study I we identified the novel BALP isoform Blx in 20% of patients with mild to moderate CKD. LÄS MER

7. 5. Changes in bone mass and skeletal structure in the postmenopausal period

   Författare :Henrik Ahlborg; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; hormone replacement therapy.; physical activity; bone strength; bone size; bone loss; longitudinal; Menopause; bone mineral density; traumatology; Kirurgi; ortopedi; traumatologi;

   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.
