13. Isolation and characterization of mesenchymal progenitors derived from the bone marrow of goats native from northeastern Brazil
PURPOSE:To characterize bone marrow progenitors cells grown in vitro,using native goats from northeastern Brazil as animal model.METHODS:Ten northeastern Brazil native goats of both genders were used from the Piauí Federal University Agricultural Science Center's (UFPI) - Goat Farming Sector. Bone marrow aspirates where taken from the tibial ridge and seede

14. Glucosamine and chondroitin sulfate association increases tibial epiphyseal growth plate proliferation and bone formation in ovariectomized rats
OBJECTIVE: The growth plate consists of organized hyaline cartilage and serves as a scaffold for endochondral ossification, a process that mediates longitudinal bone growth. Based on evidence showing that the oral administration of glucosamine sul

15. Resistência de três tipos de fixação utilizados no tratamento das fraturas do ângulo mandibular / Resistance of three types of fixation in the treatment of fractures of the mandibular angle
Fraturas do ângulo mandibular são muito freqüentes dentre as fraturas mandibulares e um das formas de tratamento é a utilização de fixação interna com placas e parafusos. Neste estudo o objetivo foi avaliar comparativamente a resistência de três tipos de fixação em réplicas de mandíbula de poliuretano, empregando-se a técnica de Champy. Foram

16. Análise mecânica e fotoelástica de sistemas de fixação interna estável utilizados para o tratamento de fraturas subcondilares da mandíbula / Mechanical and photoelastic analysis of internal fixation systems used for treatment of subcondylar mandibular fractures
Fractures of the mandibular condyle are presented as the most common injuries to the maxillo-mandibular complex, however there is still great controversy regarding treatment. The aim of this study was to assess comparatively, in vitro, by mechanical and photoelastic testing, fixation for condylar fractures with different systems. For the mechanical tests 60

17. Phylogenetic diagnosis and expanded description of the genus Mazarunia Kullander, 1990 (Teleostei: Cichlidae) from the upper Mazaruni River, Guyana, with description of two new species
We expand the description of the genus Mazarunia Kullander, 1990, explore morphological diagnostic characters for the genus and for its sister-group relationship with Guianacara Kullander & Nijssen, 1989 in a phylogenetic context, expand the description of M. mazarunii and describe two new species. Mazarunia can be diagnosed by the combination of numerous an

18. Utilização da tomografia computadorizada quantitativa como teste de resistência para avaliação de placas ósseas
Quantitative computed tomography was used to determine the radiodensity of bony plates. The CT scans provided information regarding radiodensity of bony plates and allowed to verify the uniformity of bone mineral density in their scope. The proposed methodology should be considered as another tool for determining the resistance of these biomaterials.

19. Efeitos da semicarbazida no esqueleto de ratos Wistar em crescimento
The effects of semicarbazide hydrochloride on skeletal tissues were evaluated using Wistar rats. In the animals submitted to the administration of semicarbazide, radiological examination showed bone and articular alterations with growth plates enlargement. Histological exams showed irregular patterns and proliferation of chondrocytes and excessive accumulati

20. Comparação entre métodos de fixação interna utilizadas no tratamento de fraturas do ângulo mandibular : estudo mecânico / Comparison of internal fixation methods in the management of mandibular angle fractures : mechanical study
Apesar dos diversos tipos de fixação interna existentes ainda não há um consenso quanto ao método de imobilização das fraturas do ângulo mandibular. Além disso, são poucos os estudos sobre a utilização de placas grade ultimamente lançadas no mercado. O presente estudo visou avaliar comparativamente a resistência entre três tipos de fixação i

21. The effects of severe plastic deformation on some properties relevant to Ti implants
In some types of surgical implants, such as bone screws and plates, Grade 2 Ti is seriously considered as a replacement for the Ti-6Al-4V alloy. Advantages are lower cost and the absence of Al and V, which have been identified as potentially harmful to human health. The present paper shows that the lower strength of the commercially pure metal can be enhance

22. Radiological and histopathological evaluation of experimentally-induced periapical lesion in rats
OBJECTIVE: This study evaluated experimentally-induced periapical bone loss sites using digital radiographic and histopathologic parameters. MATERIAL AND METHODS: Twenty-seven Wistar rats were submitted to coronal opening of their mandibular right first molars. They were radiographed at 2, 15 and 30 days after the operative procedure by two digital radiograp

23. Microbiota associated with chronic osteomyelitis of the jaws
Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian pa

24. ANALYSIS EX VIVO BIOMECHANICS OF TWO METHODS OF OSTEOSYNTHESIS OF PELVIS IN DOGS / ANÁLISE BIOMECÂNICA EX VIVO DE DOIS MÉTODOS DE OSTEOSSÍNTESE DE PELVE EM CÃES
Approximately 25% of all fractures in dogs involve the pelvis, of which 18-46% are iliac fractures. Conservative treatment can be performed in simple cases where minimum displacement occurs fractured fragments. However when there is severe displacement of the fragments, pelvic canal narrowing and involvement of weight bearing, surgical fixation is indicated.
