RESUMO
In the Brazilian Southeast, the production of high quality wines is attained by a new management approach called double pruning. This management changes the harvesting of wine grape (Vitis vinifera L.) from wet summer to dry winter through a two pruning procedures carried out during the year. The first pruning is done during the winter to induce a vegetative cycle (all clusters are removed) and a second pruning is done during the summer to induce the reproductive cycle. In this study, ten different rootstocks were compared in order to optimize yield and wine quality of Syrah vines conducted under autumn-winter season by double pruning approach. Syrah grapevines grafted onto 'Rupestris du Lot' and 'IAC 766' showed the highest pruning weight, while '110 Richter' and '161-49 Courdec' induced the lowest cane vigor. The average production of two seasons identified 'IAC 766', 'Kober 5BB' and 'Rupestris du Lot' as the most productive rootstocks. In both seasons, the grape quality was more influenced by the plant development status than by rootstocks. 'Syrah' wine from vigorous and high yielding rootstocks, 'IAC 766' and 'Rupestris du Lot', showed satisfactory wine phenolic composition and alcohol/acidity balance. This study showed that vigorous rootstock increased yield without compromising grape and winter wine quality of Syrah grapevines subjected to double pruning management in the Brazilian Southeast.

Introdução - Dentre as inúmeras técnicas de diagnóstico por imagem que têm sido aplicadas em Odontologia com o objetivo de reduzir as limitações impostas pelo exame radiográfic.o, deve-se ressaltar o mapeamento cintilográfico dos ossos da face por ser o único exame de caráter dinâmico, ou seja, sensível às alterações metabólicas do osso alveolar e, portanto, extremamente precoce. Métodos - No intuito de aprimorar a aplicação da cintilografia, os autores compararam quantitativamente a ocorrência de imagens hipercaptantes no mapeamento cintilográfico convencional (com fostatos marcados) e no mapeamento cintilográfico com marcação de leucócitos, em regiões de maxila e manclíbula. Resultados e Conclusão - Os dois tipos de mapeamentos cintilográficos dos ossos da face mostraram-se sensíveis às áreas hipercaptantes em maxila e mandíbula, sem diferença estatisticamente significante entre eles.(au)

Perfuraçöes iatrogênicas podem ocorrer durante a manobra de cirurgia de acesso, instrumentaçäo de canais radiculares ou até durante a manobra de preparo para retentor intra-radicular. A inflamaçäo nos tecidos subjacentes, causada pelas perfuraçöes, torna duvidoso o prognóstico do dente envolvido. Nessa revisäo, analisamos alguns materiais, além do Super-Elba, o MTA para o reparo imediato de perfuraçöes iatrogênicas. O uso do MTA mostrou ser o material mais promissor, porém necessitando de novos estudos clínicos para uma melhor avaliaçäo

Muitas vezes as urgências em endodontia podem ser apresentadas em três momentos distintos: antes, durante e após a intervençäo endodôntica. Essas urgências säo denominadas flare-ups, onde se faz necessário um atendimento em caráter emergencial, em virtude da presença de edema, ou dor e edema combinados. As razöes pelas quais os flare-ups ocorrem nem sempre säo claras. Nesse trabalho, discorreremos sobre as hipóteses de sua ocorrência e prevençäo
