1. Strontium Incorporation on Microspheres of Alginate/β-tricalcium Phosphate as Delivery Matrices
Strontium (Sr) is known to positively affect the mechanism of bone remodelling. Consequently, calcium phosphate bioceramics associated with alginate matrices containing strontium could improve bone regeneration due to gradual strontium release. This work aims to incorporate Sr on microspheres of alginate (ALG)/β-tricalcium phosphate (β-TCP) and evaluates t

2. Study of tension in the periodontal ligament using the finite elements method
Orthodontic movement is process of transformation of a physical stimulation into a force applied to a tooth, with a biological response identified as bone remodelling. Although it is possible to measure the force applied on a tooth, its distribution around the root is irregular forming areas of higher concentration of tensions, which do not correspond to the

3. Development of a methodology for bioengineering analysis of compact bones with surface remodeling using 3D boundary element method in transversely isotropic media / Desenvolvimento de uma metodologia para analise de bioengenharia em ossos compactos com remodelagem superficial pelo metodo dos elementos de contorno 3D em meios transversalmente isotropicos
Este trabalho mostra o desenvolvimento de uma metodologia para análise de problemas de bioengenharia, aplicando modelagem numérica elastostática de tensões e deformações, baseada no método dos elementos de contorno com formulação 3D para meios transversalmente isotrópicos lineares, incluindo a capacidade de simulação do comportamento de remodelag

4. Histomorphometric study of age-related changes in remodelling activity of human desmodontal bone.
To study age-related changes in human desmodontal bone remodelling, histological specimens were prepared from 42 human mandibles from individuals aged between 16 and 71 years which were obtained from autopsies. Microradiographs of horizontal ground sections and the corresponding undecalcified histological sections stained with Goldner trichrome were used for

5. Reduced bone formation in non-steroid treated patients with rheumatoid arthritis.
The cellular basis of trabecular bone loss in rheumatoid arthritis was investigated in 45 non-steroid treated patients. Mean wall thickness, an indicator of the amount of bone formed per remodelling unit, mean interstitial bone thickness, which is related to resorption depth, and the extent of trabecular surface covered by osteoid, which reflects the number

6. Remodelling of subchondral bone in osteoarthritis: a histomorphometric study.
AIMS: To determine whether remodelling of subchondral bone in osteoarthritis is related to anatomical and mechanical factors operating on the joint surface. METHODS: Ten femoral heads were examined. Patients due to have the femoral head removed because of osteoarthritis were given a double tetracycline label before surgery. The specimens were divided in thre

7. Periosteal changes in mechanically stressed rat caudal vertebrae.
When a caudal vertebra is stressed by looping the tail, remodelling results with increased formation of bone on the inner (concave) side of the loop and decreased formation on the corresponding outer (convex) side. The initial morphological changes in periosteum under stress are examined by histology, autoradiography and transmission electron microscopy. Ves

8. The penile bone and anterior process of the rat in scanning electron microscopy.
The penile bone and anterior process were made anorganic for scanning electron microscopy. The mature bone has a basal bulb and a long, cylindrical shaft bevelled at its tip to fit under a matching surface on the anterior process, giving rise to a bevelled 'suture'. A rough, resting, Sharpey-fibre bone surface covers the base and tip of the bone, the dorsal

9. Topographical variation in the calcified zone of upper femoral articular cartilage.
A series of 27 adult human femoral heads has been examined for topographical variation in 'remodelling' and other histological features of the calcified zone at the base of the articular cartilage. The specimens were obtained from necropsies; hip joints with osteoarthritic bone exposure were excluded. A tissue sample from the inferomedial aspect was compared

10. A model of the intracortical vascular system of long bones and of its organization: an experimental study in rabbit femur and tibia
The vascular anatomy of the cortical bone and the canal system are highly correlated, and the former has an important bearing on shape and microscopic lamellar structure, as it is established in the progression of the remodelling process. The classical description of a longitudinal system of canals (Havers') connected by the transversal Volkmann's canals is
