The use of medicinal plants corresponds to an ancient practice, either as an alternative medicine for the cure of several diseases, or as a method of abortion. Nevertheless, the population in general does not know the risks involved in the use of medicinal plants. In this sense, the purpose of the study was to evaluate the consumption rate of medicinal plants by women in a Basic Health Unit (BHU), on order to identify which plant species have been most frequently consumed by them, including during the pregnancy. Through an exploratory questionnaire with 48 women, it was observed that most part of the interviewees had children and the most of them cited Peumus boldus, Baccharis trimera and Cassia angustifolia, which were mainly used for stomach aches or digestives (53%), for colds (23%), menstrual cramps (4%) or to menstruate (2%). The remaining part of the study consisted in the visual and chemical analysis of the plant species cited by the interviewees, including other species that have been popularly used as a method of abortion. Comparative visual analysis of medicinal plants (Group A-C) from four different shops showed the absence of quality control concerning packing specifications and the separation of the plant material to be consumed. The analysis of the chemical profiles of these samples by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) indicated that those species belonging to the Group C were significantly different from those plants having the same identification, except for Peumus boldus, whose samples were similar in terms of chemical composition.

A-Nperp, Pg-Nperp e mandibular plane). Thirty patients (male or female), with age varying from 19 to 48 years old were analyzed. All patients were diagnosted with mandibular retrognathism and submitted to bilateral sagital mandibular advancement. All tracings were performed in lateral cephalometric radiographs obtained one week before surgery. The intraclass correlation coefficient analysis (ICC), the t test adjusted for Tukey-Kramer test and Schuirmann test were applied. The results showed that the manual tracings and Nemotec® tracing had excellent reliabilities for all measures (ICC > 0.98). The Dolphin Imaging® showed low reliability in anterior facial height (value of ICC = 0.70), Co-A (value of ICC = 0.47) and Co-Gn (ICC value = 0.49). In A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB there were no differences between the 3 tracings (p > 0.05), for the anterior facial height measures differences were found between the Dolphin Imaging® and Nemotec® tracings, but no differences were observed as compared to the manual tracing (p > 0.05), in Co-A and Co-Gn measures t Dolphin Imaging® presented a significantly lower mean than the other methods (p > 0.05). The manual tracings were equivalent in 6 of 8 measures (A-Nperp, Pg-Nperp, md Plan, SNA, SNB and Co-A), there was no equivalence between the methods in the anterior facial height and Co-Gn measures (p < 0.01). The Dolphin Imaging® method was not equivalent in any of the 8 measures. It was concluded that in the manual tracing only the Co- Gn, Pg-Nperp and SNB measures confirmed the diagnosis of mandibular retrognathism, and the Nemotec® software showed better results than the Dolphin Imaging® software.

In recent years it was possible to see a considerable growth of distance education, while the classroom teaching had a more modest growth. Thus, maintained this scenario, it will not take long for the quantitative indicators of distance education outweigh the classroom education. The distance education is evolving rapidly and changing traditional methods of acquiring knowledge and reduce inequalities caused by isolation and distance from large urban centers. This work aims to develop a videolesson and analyze its application in the teaching of statistics to a class of students of FEG, using modern techniques of distance education. To that end, was record a videolesson and developed two assessment tools, one practical and the other qualitative. The results showed that students prefer to follow the resolution of examples, with high degree of difficulty, and the audio recording is a key to the proper understanding of the same. In addition, students consider important mainstay of distance education, the fact that you can attend a class several times, whenever you need it, anywhere

Junto ao Laboratório de Fracionamento de Proteínas, desenvolveu atividades aplicando técnicas eletroforéticas (gel de agarose, eletroforese nativa em gel de poliacrilamida) em amostras de músculos de aves de interesse comercial (frangos, perus e avestruzes), tendo como co-orientador o Prof. Paulo Tadeu Figueira da Faculdade de Medicina Veterinária, PUC/PR - Toledo, onde desenvolveu atividades de análise de géis de eletroforese. Aplicou as técnicas de eletroforeses citadas em amostras de músculos e soro sanguíneo (em andamento) de tilápias (Oreochromis niloticus), bem como desenvolveu atividades de análises computacionais (VDS – PHARMACIA) e estatísticas (ASSISTAT) nos dados obtidos, resultando na participação em 7 congressos com apresentação de trabalhos. Cursou a disciplina de Genética, como aluno especial, junto à turma de Licenciatura em Ciências Biológicas, num total de 8 créditos, sendo aprovado com média 7,2

Dentre os mamíferos marinhos presentes na costa brasileira, Sotalia guianensis (subordem Odontoceti, família Delphinidae) é um dos mais comumente encontrados, possuindo ampla distribuição pela América do Sul e Central. Pelo fato de apresentar hábito costeiro, esta espécie encontra-se diretamente relacionada com impactos de origem antrópica tais como poluição, pesca acidental ou degradação de habitats. Somado a estes fatores, a falta de informações relatada pela IUCN surge como outro ponto de preocupação, visto que não se sabe de fato qual o grau de conservação dessa espécie. Por este motivo o presente estudo pretende avaliar características populacionais existentes nos grupos de S. guianensis na região do Lagamar de Cananéia, litoral sul de São Paulo, utilizando-se de microssatélites. Para tanto, aspectos referentes à diversidade genética, grau de parentesco e fluxo gênico entre áreas estuarinas e de mar aberto foram considerados. A amostragem é composta por 22 tecidos oriundos de indivíduos de mar aberto e 11 estuarinos, coletados entre os anos de 1996 e 2009. O material foi amplificado por PCR utilizando-se de oito locos específicos para a espécie. O presente estudo concluiu que a diversidade genética (número de alelos, riqueza alélica, heterozigosidade esperada e observada) ocorrente no grupo de estudo é considerada como moderada quando comparada a outras populações de S. guianensis estudadas. Após a retirada dos locos com indício da presença de alelos nulos, a população mostrou-se em equilíbrio de Hardy-Weinberg, como revelado também pelo valor de FIS. Corroborando com o nível de diversidade genética encontrado, foram avaliados baixos índices de parentesco, sem diferenças significativas entre os grupos em comparação (estuário e mar aberto), bem como entre os sexos, indicando a ausência de dispersão sexo assimétrica...

This work aims viewing weather information, by building isosurfaces enabling enjoy the advantages of three-dimensional geometric models, to communicate the meaning of the data used in a clear and efficient way. The evolving technology of data processing makes possible the interpretation of masses of data increasing, through robust algorithms. In meteorology, in particular, we can benefit from this fact, due to the large amount of data required for analysis and statistics. The manipulation of data, by users from other areas, is facilitated by the choice of algorithm and the tools involved in this work. The project was further developed into distinct modules, increasing their flexibility and reusability for future studies
