13. Whole-body vibration improves fracture healing and bone quality in rats with ovariectomy-induced osteoporosis
PURPOSE: To investigate the effect of vibration therapy on the bone callus of fractured femurs and the bone quality of intact femurs in ovariectomized rats. METHODS: Fifty-six rats aged seven weeks were divided into four groups: control with femoral fracture (CON, n=14), ovariectomized with femoral fracture (OVX, n=14), control with femoral fracture plus v

14. Quantitative ultrasound at the hand phalanges in patients with bisphosphonate-related osteonecrosis of the jaws
Patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) who received intravenous or oral bisphosphonates (BP) were selected for determination of their bone microarchitecture as a risk predictor of BRONJ development. The diagnosis of BRONJ was made based on clinical and radiographic findings. The control group consisted of healthy patients. All

15. Histomorphometric bone assessment in patients with fracture of the proximal end of the femur
OBJECTIVE: To determine whether there is a difference on the bone architecture in patients with femoral neck fracture compared to patients with intertrochanteric fractures and assess the importance of aging on bone microarchitecture in patients with proximal femoral fracture.METHODS: Biopsy of the iliac crest was made in seventeen patients between 55 and 90

16. Pharmacological management of osteogenesis
Osteogenesis and bone remodeling are complex biological processes that are essential for the formation of new bone tissue and its correct functioning. When the balance between bone resorption and formation is disrupted, bone diseases and disorders such as Paget's disease, fibrous dysplasia, osteoporosis and fragility fractures may result. Recent advances in

17. Effect of autologous stem cells on regenerated bone during distraction osteogenesis by Ilizarov technique in the radius of dogs: histomorphometric analysis
PURPOSE:To investigate by histomorphometry the distraction osteogenesis by Ilizarov technique in dog radius with the use of autologous stem cells in regenerated bone. METHODS:Ten dogs (20 radiuses) underwent the osteotomy of 20% of extension of their radiuses, and osteogenic distraction using the Ilizarov technique after this procedure at rate of 1mm per day

18. Efeitos do estrogênio, raloxifeno e extrato de soja rico em genisteína sobre o osso de ratas adultas ovariectomizadas previamente androgenizadas / Effects of estrogen, raloxifene and genistein-rich soy extract on bone of ovariectomized adult female rats and previously androgenized
INTRODUCTION: Hypoestrogenism can determine bone mineral loss, resulting in decreased bone quality. To prevent that process, several drugs are administered, which can lead, however, to important side effects. Therefore, it is questionable whether the use of estrogen associated with those substances could minimize the adverse effects and maintain bone mineral

19. Investigação da microarquitetura óssea através de microtomografia 3D / Investigation of bone microarchitecture using 3D microtomography
X-Ray Computed Microtomography (uCT) is a nondestructive technique used to study the internal structure of bones with a spatial resolution of the order of microns. In this study, six pairs of bone samples (femur mouse) were studied by uCT. The tests were conducted in the absence or presence of aluminum filters (thickness of 0.25, 0.50 and 0.75 mm), using thr

20. Ação do paratormônio humano (1-34) no tecido ósseo de ratas osteopênicas. / Action of parathyroid hormone (1-34) on bone tissue in osteopenic rats.
Introduction: Bone remodeling depends upon a variety of systemic and local factors. Systemic factors that have a direct effect include the parathyroid hormone which together with other factors maintains bone homeostasis. Biosynthetic human parathyroid hormone (1-34) [hPTH(1-34)] has been used to stimulate bone formation in patients with osteoporosis. However

21. Estudo do consumo alimentar, estilo de vida e risco de osteoporose em idosos acompanhados pelo NAI/UNATI/UERJ / Study of food consumption, lifestyle and risk of osteoporosis in elderly accompained by NAI/UNATI/UERJ
The absolute and relative increase in the elderly population in Brazil, taken place in the last 30 years, was associated with a epidemiological transition in the morbidity-mortality situation. Among the most common chronicle diseases to affect the elders osteoporosis stands out. This is a progressive disease, characterized by low bone mass and deterioration

22. CaracterizaÃÃo de diferentes granulados e comprimidos de carbonato de cÃlcio a partir do pà de concha de ostras / CHARACTERIZATION OF DIFFERENT GRANULATES AND TABLETS OF CALCIUM CARBONATE FROM OYSTER SHELL POWDER
Osteoporosis is a progressive systemic skeletal disease, characterized by bone mass reduction and deterioration of the bone micro-architecture, leading to fragility and with consequent increase of fracture susceptibility. The preliminary and secondary target of pharmacotherapy in osteoporosis is to prevent bone fractures. Initial treatment of osteoporosis mu

23. Desenvolvimento de um modelo experimental para o estudo da osteoporose / Development of an experimental model to study osteoporosis
Osteoporosis is a disease characterized by low bone mass and deterioration of the microarchitecture of the skeleton, leading to an accentuated bone fragility and a consequent increase in the risk of fractures. Nowadays osteoporosis is being considered one of the largest and more preoccupying health problems in the world, which strikes men and women. An anima

24. Role of Trabecular Microarchitecture in Whole-Vertebral Body Biomechanical Behavior
The role of trabecular microarchitecture in whole-vertebral biomechanical behavior remains unclear, and its influence may be obscured by such factors as overall bone mass, bone geometry, and the presence of the cortical shell. To address this issue, 22 human T9 vertebral bodies (11 female; 11 male; age range: 53–97 yr, 81.5 ± 9.6 yr) were scanned with μC
