Item Acesso aberto (Open Access) Disputas pelo monopólio da prática odontológica e a criação da Escola Livre de Odontologia do Pará (1911-1914)(Universidade Federal do Pará, 2016-12) LIMA, Marcelino Carmo de; NASCIMENTO, Sulenir Candida da Silva; ALVES, Jose Jeronimo de AlencarThe objective of this research is to analyze the newspapers published in the State of Pará, in the period that preceded the creation, in 1914, of the Escola Livre de Odontologia do Pará, when dentistry was still practiced both by professionals trained in schools located outside the State and by the others. We find that the newspapers, the Estado do Pará and A Província do Pará, in the period before the creation of the Escola that is, from 1911 to 1914 published several news related to the formation and practice of dentistry. What was this news? We found that they expressed, above all, the controversies among the holders of diplomas obtained in schools of dentistry outside the State that sought to exclude the others. The claims about the monopoly of the profession, therefore, as the news shows, began even before the creation of the Escola do Pará.Item Acesso aberto (Open Access) Phytosterols isolated from endophytic fungus Colletotrichum gloeosporioides (Melanconiaceae)(Instituto Nacional de Pesquisas da Amazônia, 2016-03) CARVALHO, Josiwander Miranda; PAIXÃO, Luanna Karyna Olimpio da; DOLABELA, Maria Fâni; MARINHO, Patrícia Santana Barbosa; MARINHO, Andrey Moacir do RosárioEndophytic fungi are fungi that colonize internal tissues of plants. There are few studies of compounds isolated from endophytic fungi of Amazon plants. Thus, the aim this study was the isolation and structural identification of sitosterol (1), stigmasterol (2), sitostenone (3), squalene (4), ergosterol (5) and ergosterol peroxide (6) from fungus Colletotrichum gloeosporioides isolated as endophytic from Virola michelli, a typical Amazon plant, used in folk medicine against skin infection. Compounds were isolated by chromatography column on silica and identified by 1 H and 13C NMR and MS. The presence of phytosterols in fungi is rare and this is the first report of the isolation of the phytosterols sitosterol, stigmasterol and sitostenone from the genus Colletotrichum.
