The root resorption is one of the possible sequels of greater complexity to the orthodontist, the difficulty of detection and be asymptomatic. The presence, during the orthodontic treatment, is linked to a multifactorial origin, a complex combination of biological activities, anatomical, physiological, genetic variables and mechanical forces. Thus, the aim of this study was perform to critical literature review related to root resorption in orthodontic movement. Were included articles published between 2004 to 2014, indexed in the PUBMED database. Used descriptors contained in the Mesh, being adopted as inclusion criteria: clinical trials in humans, only articles that had clear ideas and objective, articles with English language. The search strategy used resulted in 24 articles and after applied the inclusion and exclusion criteria, 11 articles remained. Based on the results of this study it was concluded that heavy forces of intrusion, inclination and torque leads to a greater degree of root resorption; its etiology is multifactorial, the periodic radiographic control during treatment is needed and further studies are suggested to identify more specifically the causes and risk factors for root resorption.

A menopausa é uma das mudanças fisiológicas caracterizadas pelo encerramento dos ciclos menstrual e ovulatório, ocorrendo nas mulheres entre a quarta e a quinta década de vida. Com ela, ocorre uma diminuição na produção de estrógeno, um importante hormônio que atua em muitos processos fisiológicos do indivíduo, como a regulação do sistema esquelético. O declínio nos níveis de estrógeno resulta em perda de densidade mineral óssea, aumento do risco de fratura, bem como no aparecimento de doenças ósseas, como a osteoporose, um processo patológico onde há o aumento na reabsorção de cavidades que não são completamente preenchidas por osso neoformado. Além disso, a deficiência de estrógeno pode causar muitas mudanças na saúde bucal do indivíduo. Na presença de uma infecção bacteriana no tecido pulpar, essa deficiência pode agravar a periodontite apical. Vários medicamentos têm sido estudados como potenciais agentes terapêuticos para suprir a deficiência de estrógeno. Essas drogas têm como objetivo reduzir o risco de fraturas e prevenir a perda óssea e distúrbios cardiovasculares e mentais resultantes de deficiência hormonal pós-menopausa. O raloxifeno (RLX), é uma das drogas terapêuticas mais estudadas, demonstrando prevenir a perda óssea. Mesmo com a indicação e benefícios do raloxifeno no metabolismo ósseo e na manutenção da densidade óssea, estudos sobre o seu papel na infecção endodôntica em organismos osteopênicos precisam ser realizados.

As demonstrações experimentais são atividades de grande tradição na História da Ciência, sendo realizadas desde 1660 na Royal Society, por grandes expoentes da Física, com o objetivo de promover a divulgação dos conhecimentos científicos desenvolvidos.Com o objetivo de contribuir com a melhoria e o interesse dos alunos pelos estudos das Ciências Exatas, bem como a conscientização destes sobre conceitos relacionados à Energia e seu impacto sobre a sociedade e sobre o meio ambiente, temos realizado atividades de demonstrações experimentais, denominadas de “Show de Energia”, nas escolas públicas de Ensino Médio de cidades da Região de Guaratinguetá, interior do Estado de São Paulo. Em cada um dos shows realizados entrevistamos os alunos, através de um questionário estruturado, buscando avaliar o impacto dessa atividade na motivação dos estudantes para o aprendizado de conceitos científicos. Os resultados apontam para a grande influência que a realização dos shows tem exercido sobre a motivação dos estudantes.

The Creative Economy is an experimental laboratory for the creation , innovation , invention and reinvention of the universe of media - analog and digital . The scenery in the media and converging technologies favors the process of “ creative destruction and destructive creation “ of this field . The mapping of basins and technological corridors distributed through the territory of concentrated areas creates an infrastructural chassis for the production of content , information and entertainment . As locus and logos of immaterial production , digital ecology that gives speed to the flow of production - planning, fundraising , publishing , distribution and enjoyment - and allows the dispossession of their local clusters , the fragmentation and dilution of their creative chains . The collective cultural production and creation appropriating these capilarizados articles and produce content against political, economic and social status quo . The land is fertile and favorable to the emergence of radical media and rebels that recreate the public sphere , and edit poor public spheres , alternative , radical and efficient , the tactical point of view . This article aims to contribute to studies and research that scour the ecosystem of the media for understanding the management of their creative processes, actors and critics of tangible and intangible resources that support their communication actions .

The Brazilian textile industry has been a highlight in the global economy. Connected with this high economic performance there is the water consumption and the generation of great volumes of wastewater which present high concentrations of dyes and chemical substances. One of the main techniques used in the treatment of textile effluents is adsorption, which has the activated carbon as the main adsorbent. Recently, studies have been developed to find alternative materials to activated carbon and exhibiting good adsorption capacity of dyes. The aim of this work is to study the potential of sawdust as adsorbent of low cost to remove the dye Direct Green 26. The results of this type of dye removal were obtained through the study of adsorption isotherms obtained by spectrophotometry in the UV-visible region analyzed by the Langmuir model. Finally, a comparison was made of these results with those of other adsorbents. Results showed that the average removal of dye, using sawdust, was 78.8% for an initial concentration of 500mg / L and the maximum adsorption capacity of 119mg / g. These results demonstrate the great potential of sawdust as an adsorbent for the dye Direct Green 26.

The mast cell tumor (MCT) is the second most common type of tumor in dogs. It is characterized by uncontrolled proliferation of mast cells in the skin. Treatment involves surgical resection, chemotherapy and radiotherapy. Recently, new treatment protocols have been developed, such as the use of tyrosine kinase inhibitors. With the increasing knowledge about the genome and the evolution of methods in molecular genetics, drugs with specific molecular targets are surely going to become promising therapeutic modalities in the near future. Besides being involved in the normal cell cycle, some studies suggest that tyrosine kinases have a fundamental role in neoplastic processes. Therefore, some strategies such as the development of antibodies anti-receptors for tyrosine kinases and small-molecule tyrosine kinase receptor inhibitors have been developed in an attempt to inhibit tumor development. The purpose of this review is to describe the use of tyrosine kinase inhibitors in the treatment of mast cell tumors in dogs.
