1. 1. Survival of onlay bone grafts. A study in the adult rat

   Författare :Monica Gordh; Lunds universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

   Sammanfattning : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

3. 2. Physical activity, bone gain and sustainment of peak bone mass

   Författare :Taru Tervo; Anna Nordström; Peter Nordström; Jon Karlsson; Umeå universitet; []
   Nyckelord :BMD; physical activity; men; athletes; trabecular bone; cortical bone; self-perceived health; MEDICINE; MEDICIN; medicin; Medicine;

   Sammanfattning : Weak and osteoporotic bones are an increasing cause of mortality and painful physical impairment among the elderly, especially in the Western world. Bone mineral density (BMD, g/cm2) accrual during childhood and adolescence is thought to influence an individual’s risk of osteoporosis and the related fractures. LÄS MER

4. 3. 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.

5. 4. Organochlorines and bone : Effects of organochlorines on bone tissue morphology, composition and strength

   Författare :Monica Lind; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; Ekotoxikologi;

   Sammanfattning : From results presented during the last decade, it is obvious that the skeleton is a targetorgan for a number of persistent organochlorines. So far, however, little attention hasbeen paid to this subject. LÄS MER

7. 5. Bone density, bone geometry and bone development in young men - the importance of pubertal timing and fracture history

   Författare :Anna Darelid; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peak bone mass; bone mineral density; bone development; fracture; young adulthood; men;

   Sammanfattning : Background and objective: Peak bone mass, the maximal bone mass attained in young adulthood, is an important factor of the lifetime risk of developing osteoporosis. The aim of this thesis was to study the development of bone mineral density (BMD) and bone geometry around the time of peak bone mass in men, and also to investigate the association between pubertal timing, fracture history, bone turnover markers and BMD and bone geometry in young men.
