1. 1. Human embryonic stem cells for bone engineering applications

   Författare :Giuseppe Maria de Peppo; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human skeleton; bone; bone defects; bone regeneration; regenerative medicine; tissue engineering; biomaterials; scaffold; biocoral; titanium; osseointegration bioreactor; human stem cells; embryonic stem cells; mesenchymal stem cells; embryonic-derived progenitors; osteogenic differentiation; mineralization; immune response; in vitro; in vivo;

   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

3. 2. Multimodal and multiscale characterization of bone and bone interfaces in health and disease

   Författare :Chiara Micheletti; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osseointegration; characterization; mineralization; ultrastructure; diabetes; osteoporosis; MRONJ; surface functionalization; local drug delivery; titanium; bioactive glass; imaging; spectroscopy; microscale; nanoscale; micro-computed X-ray tomography; micro-Raman spectroscopy; scanning electron microscopy; transmission electron microscopy; PFIB-SEM tomography; electron tomography;

   Sammanfattning : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. LÄS MER

4. 3. 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.

5. 4. Effects of Interleukin-4 and Interleukin-13 on Bone

   Författare :Carl-Johan Silfverswärd; Olle Nilsson; Östen Ljunggren; Kenneth Jonsson; Li Felländer-Tsai; Uppsala universitet; []
   Nyckelord :Medicine; Bone; Osteoblasts; Interleukin-4; Interleukin-13; Knockout; Medicin;

   Sammanfattning : Cytokines play important roles in bone metabolism, participating in the complex interplay necessary for normal bone formation and turnover. The aim of the present thesis was to investigate the effects of two anti-inflammatory cytokines, interleukin-4 (IL-4) and interleukin-13 (IL-13) on bone. LÄS MER

7. 5. Studies on nutrition, body composition and bone mineralization in healthy 8-yr-olds in an urban Swedish community

   Författare :Susanne Eriksson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body composition; bone mineralization; dual energy x-ray absorptiometry; healthy; lipids; metabolic markers; overweight; physical activity;

   Sammanfattning : Background: The incidence of welfare diseases including overweight in childhood is increasing worldwide. The results from a study of healthy pre-school children showed that in a population with well educated parents 17% of the children were overweight or obese at the age of 4 years. LÄS MER
