1. Two and three-dimensional morphometric analysis of trabecular bone using X-ray microtomography (µCT)
INTRODUCTION: Trabecular bones have a porous microstructure and can be modeled as linear elastic solids, heterogeneous and anisotropic. In the literature, few investigations have compared the two- dimensional (2D) and three-dimensional (3D) morphometric analyses of cancellous bone. METHODS: In this investigation eighteen cylindrical samples of cancellous bon

2. Papel dos receptores nucleares ativados por proliferadores de peroxissomos (PPAR) na periodontite induzida em ratos. / Role of peroxisome proliferator activated nuclear receptor (PPAR) in induced periodontitis in rats.
Este estudo investigou o efeito da Roziglitazona (RTZ) sobre a perda óssea alveolar induzida pela periodontite (POAIP). Durante 3 semanas, ratos receberam sal puro de RTZ (i.p.) ou a formulaço comercial AvandiaÒ (v.o.); os grupos controles receberam os repectiovos veículos (DMSO ou CMC). Duas semanas após o inicio do tratamento

3. FARELOS DE ARROZ DESFITINIZADOS NA NUTRIÇÃO DE JUNDIÁ (Rhamdia quelen) / DEPHYTINIZED DEFATTED RICE BRAN IN SILVER CATFISH (Rhamdia quelen) NUTRITION
This survey was conducted for the purpose of evaluating the performance, metabolism, bone mineral deposition and phosphorus excretion in feces of Rhamdia quelen juvenile fed with defatted rice bran which phytic acid was extracted or degraded. The experiments for evaluating the performance and metabolism and fecal collection were conducted in recirculating wa

4. Ação de fração do hormônio paratireóideo no metabolismo ósseo: estudo experimental em ratos / Effect of human parathyroid hormone fragment on bone metabolism: experimental study in rats
O hormônio da paratireóide (PTH) tem sido utilizado como um agente anabólico ósseo para o tratamento de condições de osteopenia / osteoporose, prevenção e consolidação de fraturas. O papel do fator de crescimento semelhante à insulina I (IGF-I), como um potencial mediador dos efeitos anabólicos do PTH, é controverso. O rato dwarf pode ser adequa

5. Interação do alendronato e da vitamina K no metabolismo osteomineral de ratas ovariectomizadas
The bone is a specialized form of connective tissue that provides support for metabolic and biomechanical throughout the body. Thus, the bone is very dynamic, with constantly renewing itself. His integrity therefore depends on the balance between the processes of formation and resorption. The loss of this balance alters both the structure of organic matrix a

6. Análise morfométrica 2D e 3D de amostras de osso trabecular utilizando microtomografia tridimensional por raio-X / 2D and 3D morphometric analysis of trabecular bone using X-ray tridimensional microtomography (müCT)
Trebecular bones have a porous microstructure and can be modeled as a linear elastic solid, heterogenous and anisotropic. The x-ray tridimensional microtomography (müCT) has been worldwide used for the assessment of trabecular bone in investigations related to bone quality and aimed to the diagnostic of bone metabolic diseases such as osteoporosis. In the l

7. Parâmetros mecânicos, físicos e químicos na avaliação de mandíbulas de ratos deficientes em esteróides sexuais / Mechanical, physical and chemical parameters in mandible evaluation of sex steroid deficiency rats
The increase in the life expectancy has been raising the occurrence of common degenerative alterations in aging population, as osteoporosis. This systemic disease is also frequent in hypogonadism and affects the bone metabolism, included mandibular bone. The aim of this study was to evaluate how sex steroid deficiency, induced by orchiectomy (ORX) or ovariec

8. Efeitos do cloreto mercúrico sobre o tecido ósseo de ratos
The mercury is used in the industry, medicine, agriculture and other fields. However, little is known about its involvement with the bone metabolism. The aim of this study was to evaluate the physical, biochemical and biomechanical bone parameters in adult rats contaminated with mercuric chloride during the development phase. The animals were separated as co

9. Avaliação do sistema osteoprotegerina e RANKL em pacientes com artrite idiopática juvenil de início poliarticular / Osteoprotegerin and RANKL system in patients with polyarticular-onset juvenile idiopathic arthritis
OBJETIVO: Determinar os valores séricos do ligante do receptor do ativador do fator nuclear Kappa B (RANKL) e da osteoprotegerina (OPG) em pacientes com Artrite Idiopática Juvenil de início poliarticular (AIJp) em atividade e avaliar a possível correlação destes valores com a presença radiológica de erosões ósseas. MÉTODOS: Trinta pacientes do sex

10. Levels of metabolizable energy and crude protein in rations formulated according to the concept of ideal protein and phytase for piglets of 15 to 35 kg / NÃveis de energia metabolizÃvel e de proteÃna bruta em raÃÃes formuladas segundo o conceito de proteÃna ideal e fitase para leitÃes dos 15 aos 35 kg
Two experiments were conducted in the Swine Production Sector of the Animal Science Department at UFLA to verify by using the metabolism, performance assay, blood parameters and comparative slaughter, the effects of different levels of metabolizable energy (ME) and crude protein (CP) in rations formulated according to the ideal protein concept and phytase fo

12. A fase estrogênica altera a resposta do osso e do metabolismo mineral de ratas com hipertireoidismo?
The effect of the estrogenic phase in the bone and in the mineral metabolism was studied in Wistar adult female rats kept under euthyroidism or hyperthyroidism for 60 days. The rats were divided, according to the stage of the estrous cycle, into four groups: 1) euthyroid (proestrus-estrus), 2) euthyroid (metaestrus-diestrus), 3) hyperthyroid (proestrus-estru
