Segundo a Organização Mundial da Saúde (OMS), leishmanioses são antropozoonoses e estão entre as seis doenças tropicais de maior importância no Velho Mundo e nas Américas. São endêmicas em 88 países e estima-se que sua prevalência seja de 12 milhões de casos no mundo. Nas duas últimas décadas, o número de casos tem aumentado, assim como sua ocorrência geográfica. No Brasil, é uma realidade em diversos estados, apresentando perfis epidemiológicos diferentes. A terapêutica empregada atualmente conta com poucos fármacos, em uso há mais de 40 anos, e que apresentam potencial nefro, hepato e cardiotóxico. Além disto, são contraindicados a idosos e gestantes, o que caracteriza mais um entrave à terapêutica atual. Tendo em vista a imensa biodiversidade brasileira, uma fonte alternativa para o tratamento destas e outras inúmeras enfermidades é a busca de novas moléculas por meio da pesquisa com extratos vegetais e seu fracionamento, a partir de diferentes espécies de plantas. Este trabalho avaliou a atividade leishmanicida do extrato acetato de etila, frações e subfrações obtidas da planta Baccharis trimera (Less.) DC sobre a espécie Leishmania amazonensis. Os ensaios biológicos foram realizados in vitro pelo método colorimétrico de MTT (Brometo de 3-(4,5-dimetiltiazol-2-il)-2,5-difenil-tetrazólio) utilizando formas promastigotas do parasito e macrófagos da linhagem J774, para estudos de citotoxicidade. Os testes foram realizados em triplicata, utilizando-se microplacas de 96 orifícios. Como resultado, três frações (CI50 = 23,56 μg/mL; 29,89 μg/mL; 42,31 μg/mL) e cinco subfrações (CI50 < 1,56 e CI50 = 5, 07 μg/mL ; 5,21 μg/mL; 24,61 μg/mL) apresentaram interessante potencial leishmanicida, sendo que duas destas subfrações também demonstraram baixa citotoxicidade (IS = 64,1). A partir de análises cromatográficas das frações e subfrações... (Resumo completo, clicar acesso eletrônico abaixo)

This paper analyzes the new trends of Brazilian migration to Japan, more specifically in the process of redefining its territoriality on the political and administrative Japanese territory. This migration, known as Dekassegui movement, is based on the flow of Brazilians of Japanese descent in this country. The working part of a periodization of the movement, considering the political and economic situations of countries and account for aspects of the difficult adjustment of the pioneers, the change the temporal expectation of return and search for repossession of these immigrants in their most recent time frame After more than 27 years of migration is still common difficulties in the integrating the Brazilian front of Japanese society, and it is in this context, however, that migration projects take new directions, new meanings are created networks, strengthens relationships, change and so plans to build a new interaction with the territory. To understand this process, we consider as a theoretical analysis and territorial consolidation of field research in Japan, through questionnaires, to identify the processes of social integration of immigrants

This qualitative research was performed with the goal of investigating the contributions of theoretical and methodological perspectives in the alphabetization process, aiming to train proficient writers of texts with communicative function. Hence, such were the goals established for this research: giving a retrospective look on the synthetic and analytic methods of teaching literacy; verifying the possibilities and limits of theoretical and methodological approaches of acquiring the ability to write and identifying the teachers’ ideas concerning basic concepts (such as literacy, text and textual genres) imbued in the teaching of writing; and establishing which activities they develop in the course of teaching whether the pedagogical practices of the teacher observed contributed to the formation of students who were capable of producing significant texts of diverse genres, suitable to the objectives, to the readers, and to the context of the circulation of texts. The research was done in a public elementary school, in a 2nd grade class of the city of Jaú. Subjects of the research were four teachers and twenty-eight children. For this work, two instruments were used for data collecting: a questionnaire and direct observation, registered in research diaries. Among the observations made were that, although there are many studies on literacy, the practices actually adopted in class are empirical in nature and do not contribute to the process of developing individual writing or reading skills at all; rather, it is only valued the ability of establishing relations between phonemes and graphemes; literacy teachers do not have adequate knowledge of concepts of literacy, teaching, text and textual genres, valuing only one methodological theory and disregarding other contributions on the field of text production

The lexicon of a language shows the way the community views the world, in its different aspects. Hence, through the study of the lexicon we can get a clearer idea of the different forms of prejudice present in a society. The aim of this study is to present reflections and theories concerning obscene lexical items and linguistics taboos associated to them, and to discuss the linguistic prejudice that this kind of lexicon may suffer.

September 11 has originated a wide range of artistic manifestations which have not only searched for plausible explanations for the tragedy, but also tried to review the events. In this sense, this paper aims at showing how a novel reevaluates this episode. The attacks made the United States experience a strong sense of vulnerability, triggering reactions from the American government, whose quick action was translated into a new national security strategy, associated with the war on terror. This paper analyzes the narrative strategies employed by the American author Don DeLillo in his novel Falling Man (2007) in order to reevaluate that tragedy. The debate of the topics is based on texts concerning the relationship between literature and history, postmodern fiction and issues on terrorism. This study contributes to enrich the discussion related to the events that led to the catastrophe and its aftermath, examining characters and groups linked to the September 11 terrorist attacks, revealing multiple truths subjected to social, ideological and historical conditions.

The language in use in a society is product of a culture and reflects the way a community thinks. Therefore, the lexical units, through the meanings assigned by a social group, establish a specific look of the universe. We intend to demonstrate that for the denomination of the sexual organs of the human body it usual to avoid the official anatomical terminology – relegated to the contexts of great formality – and to adopt other lexical items during informal situations. This paper reflects about some sociocultural aspects of the forbidden language, that encloses the erogene zones. Using as theory the studies of Lexicology and the obscene lexicon, we intend to verify this lexical typology based in our corpus, and stimulate reflections about the use and the substitution of the official terminology, showing that there are variations in relation to the age and gender of the speakers. We intend, with this research, to demystify some prejudices related to the erotic-obscene lexicon, its use and its creation and to stimulate reflections.

This paper presents a quantum search algorithm implementation with small modifications. The algorithm idea is to be hybrid, capable to run on classical systems and quantum systems. We present the concepts of quantum search and introduced a pseudo-framework able to generate code for classical computers (C++) and quantum computers (QCL). The algorithms were submitted to simulations, which resulted in a comparative study of the operation of Grover’s algorithm on both systems, carrying out searches in a mass of data in XML format files. As a result, we see very similar numbers between classical and quantum systems, this creates an expectation that the search in real quantum computers is much more efficient.

Among the fruit species of the Brazilian Cerrado, the pequi is much popular in regions where it is extracted. Often it used in typical dishes, on the industry medicinal, cosmetic and handmade, also it studied its potential to produce fuel. Thus, this article sought to ponder about the disclosure of this fruit in the press, by means of the search system's site Folha de S. Paulo and applying content analysis, proposed by Bardin, beyond bibliography and documentary research. The justification for this research is that the pequi is a fruit of great importance in the economy and sustainable, yet little is spoken about it in the mainstream media. The result is that, by the analysis, little is said about the pequi media and its focus, is principally, cultural journalism, in culinary.

A quimioterapia e uma das formas de tratamentos para o câncer, cujo processo e pela aplicação de medicamentos que alteram a síntese de DNA, interrompendo a divisão celular. No caso do câncer de pulmão, a difículdade está no fato de que as células cancerígenas criam quimiorresistência após um determinado período de tempo. Se o indivíduo desenvolver o câncer de pulmão novamente, deverá ser aplicado outro quimioterápico no paciente, e assim por diante. Nos tratamentos atuais são utilizados combinações de drogas para contornar o problema da quimiorresistência. Este trabalho utilizou a biologia de sistemas para encontrar novos alvos protéicos para auxiliar no desenvolvimento de novos quimioterápicos para o tratamento do câncer de pulmão. Foi construída uma rede baseada nos alvos protéicos já conhecidos. A rede foi expandida com o intuito de buscar quais são as proteínas que interagem com os alvos protéicos á conhecidos. Após a expansão, foram utilizadas análises de centralidades para evidenciar as proteínas mais importantes na rede, e correlacionamos com informação de expressão gênica para verificar se as proteínas mais importantes do ponto de vista topológico estão diferencialmente sub ou super expressas. A análise de centralidade junto a mostra dos dados de expressão gênica convergiu para um bom resultado, foi possível evidenciar algumas proteínas que podem ser utilizadas como novos alvos quimioterápicos
