Abstract: The text aims to lead to a reflection on the importance of scientific knowledge for decision-making in different sectors of society and the commitment of media not to restrict itself to factual coverage, but to contribute to the educational process. The reform of the Brazilian Forestry Code in 2011 occupied large spaces both in Congress and the media. Brazilian Deputies approved the proposal on the expansion of deforestation without hearing scientists. This measure impacts the Brazilian goal of emissions of gases that enhance the greenhouse effect. The "Folha de S. Paulo" defended in editorials, the change in legislation but only supported in favor of the manifestation of the scientists after the measure had been approved. The society was left out of this discussion, because it was not built a scientific knowledge capable of providing an understanding of the significance of this reform and the environmental consequences that directly affect life on Earth. This article examines the coverage of the "Folha de S. Paulo" of Brazil's Forestry Code reform from the perspective of discourse analysis and concludes that the contract between reader and the newspaper has proved unsuitable, because it was expected more analysis and reflection of issues of such importance.

Brazilian Journal of Otorhinolaryngology , 2012, DOI: 10.5935/1808-8694.20120006
Abstract: Osteoma periférico é uma neoplasia benigna, com baixa taxa de recorrência. Sua incidência é rara nos maxilares e a mandíbula é mais afetada do que a maxila. Na maioria dos casos, é descoberto durante exames radiográficos de rotina. OBJETIVO: O objetivo deste trabalho é mostrar a experiência dos autores no tratamento desta neoplasia. MéTODO: Em um estudo retrospectivo de janeiro de 2002 a dezembro de 2007 foram avaliados dez casos de osteoma periférico na regi o maxilofacial, tratados cirurgicamente por remo o completa da les o, seguido de confirma o histológica. Nenhum dos casos estava correlacionado com a síndrome de Gardner. RESULTADOS: Nesta série avaliada, a incidência desta neoplasia foi maior no gênero feminino (1,5:1), com média de idade de 39 anos, sem predile o por faixa etária. Um dos pacientes apresentou recidiva da les o após dois anos da primeira cirurgia, tendo sido submetido à nova interven o, sem sinais de recidiva após três anos e seis meses de acompanhamento. CONCLUS O: O tratamento cirúrgico para o osteoma periférico é efetivo, com baixa taxa de recidiva. Peripheral osteoma is a benign neoplasm, with low recurrence rate. Its incidence is rare in the jaws and the mandible is more affected than the maxilla. In most cases it is discovered during routine radiographic examinations. OBJECTIVE: The aim of this study is to show the author's experience regarding the treatment of this neoplasm. METHODS: A retrospective study from January 2002 to December 2007 including ten cases of peripheral osteoma in the maxillofacial region which were treated surgically by removal of the lesion followed by histological confirmation. None of the cases were correlated with Gardner's syndrome. RESULTS: In this series the incidence of this neoplasm was higher in females (1.5:1) with a mean age of 39, without age preference. One of the patients had lesion recurrence two years after the first surgery, having been submitted to another intervention, with no signs of relapse after three years and six months of follow-up. CONCLUSION: Surgical treatment is effective for peripheral osteoma with a low recurrence rate.

Abstract: OBJETIVO: Avaliar a frequência da muta o V600E do gene BRAF em pacientes com mais de 65 anos de idade submetidos à tireoidectomia, correlacionando sua presen a ou ausência com as diferentes les es histológicas, com as variantes e com fatores prognósticos do carcinoma papilífero. MéTODOS: Foram avaliados 85 pacientes com mais de 65 anos de idade submetidos à tireoidectomia, analisando a muta o BRAF V600E através de rea o de PCR-RT realizada após a extra o do DNA dos blocos de parafina. RESULTADOS: Detectou-se ausência ou presen a da muta o BRAF V600E em 47 pacientes (55,3%). Entre os 17 carcinomas papilíferos estudados, sete apresentavam a muta o (41,2%). Demonstrou-se associa o estatística entre a presen a desta muta o e a variante clássica do carcinoma papilífero, além de tendência de associa o com o extravasamento tireoideano. CONCLUS O: A muta o BRAF nos pacientes idosos também é exclusiva do carcinoma papilífero e tem frequência expressiva. Além disso, está relacionada à variante clássica e, possivelmente, ao extravasamento tireoideano. OBJECTIVE: To evaluate the frequency of the BRAF V600E mutation in patients over 65 years of age undergoing thyroidectomy, correlating its presence or absence with the different histologic lesions, their variants and with prognostic factors of papillary carcinoma. METHODS: We evaluated 85 patients over 65 years of age who underwent thyroidectomy, analyzing the BRAF V600E mutation by RT-PCR performed after DNA extraction from the paraffin blocks. RESULTS: The study detected the presence or absence of BRAF V600E mutation in 47 patients (55.3%). Among the 17 papillary carcinomas studied, seven had the mutation (41.2%). There was a statistical association between the presence of this mutation and the classic variant of papillary carcinoma, and a trend of association with thyroid extravasation. CONCLUSION: BRAF mutation in the elderly is also exclusive of papillary carcinoma and is often significant. Furthermore, it is related to the classic variant and possibly to thyroid extravasation.

Abstract: Seedling production is one of the crucial points in the forest companies and studies have been carried out to identify the most appropriate method of production. The utilization of phenolic foam in substitution of plastic tube and organic substrate to grow eucalypt clonal cuttings was evaluated. Four experiments were established, two experiments were set up in nurseries (experiments 1 and 2) and two in the field (experiments 3 and 4). All experiments were composed by four treatments: 1 – conventional system – plastic container of 55 cm3 with commercial substrate (pine bark, vermiculite and peat), 2 - small foam (60 cm3), 3 - medium foam (75 cm3) and 4 - large foam (90 cm3). In all experiments the mortality and the root and shot biomass production were evaluated. In the experiment 1, the plants in the small foam presented lower mortality rate (1%) and the conventional system showed the highest mortality rate (15%) and the large foam showed highest value of the shoot biomass. In experiment 2, the mortality rate was 40% for the foam treatments with higher values when compared to the conventional treatment (16%). In the experiment 3, field experiment, was not observed tree mortality or differences in biomass production among the treatments. In the experiment 4, was observed better tree response to water stress of the stocks in foams, probably because their larger volume. The plants in medium and larger foams showed 3% of mortality, while the conventional system had 25% and the shoot biomass production was highest in the larger foam treatment.
