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

The present investigation intended to understand how Didatic has been interpreted by teachers who work with this discipline in undergraduate courses. We assume that there are still many controversies and contradictions in consideration of the epistemological status of didactics, and that this knowledge object is on constant review by professionals. Initially we were seeking evidence in the plans of courses, however, this search has put us in a situation of confusion, of uncertainty and highlighted structural problems which, at first, prevented us from using pure and simple of the contents of the plans. We analyzed 76 lesson plans, allocated to institutions in different Brazilian states, different types of institutions and the diversity was so great that led us to characterize this study as exploratory and tell us the relevance of analyzing them in the perspective of "facets". To deepen the understanding we were interviewing teachers and two focus groups conducted with teachers of Teaching. Triangulating the analysis of plans, with the reflections from the interviews, the speeches and also in the focus group data, observation of teaching practice, we put some insights on issues, even though preliminary and will require further research.

Early this century, several crises are intertwined and the environmental crisis is the most global of them all. In this context, emerged as an environmental education learn to overcome the crisis. This article aims to discuss the ideas of biology teachers in the city of Piracicaba-SP on Environmental Education and from there to reflect on the theme of inclusion in the initial training of teachers. The methodology used a structured questionnaire-based instrument VOSTS (Views on Science-Technology-Society), produced by Aikenhead and Ryan (1992) and the data were analyzed qualitatively. The results indicate that the biology teachers surveyed still have a naive conception of environmental education and training courses need to commit to structural and curricular changes that make the effective insertion of the subject in teacher training in the region studied.

This study aimed to analyze the limits and possibilities of a didactic sequence, addressing the concept of proportionality in the learning of students in 5th year of elementary school. From the results of the Diagnostic Assessment Initial applied to students in a class of 5th grade of elementary school, we selected eight (8) students who participated in the constituent activities of that instructional sequence. For the development of this sequence were used theoretical elements of Genetic Epistemology (Piaget, 1990), the theory of fields of Conceptual Vergnaud (1996) and the definition of instructional sequence proposed by Zabala (1998). Finally, after 20 days of application of these activities, we applied the Diagnostic Assessment Final aimed at investigating which concepts related to proportionality were built by the participating students. By analyzing the collected data, it can be concluded the following about the possibilities of teaching sequence: 1) students who, in Diagnostica Home Assessment used the multiplication algorithm, but also did not indicate the comparison between quantities are now performing; 2) students who, in the Diagnostic Assessment Initial, used the addition algorithm, now gradually are using the multiplication algorithm; 3)students who, in the Diagnostic Assessment Initial, could not solve problems involving the idea of proportionality, are now resolving, however, still use, in large part, the addition operation as a strategy for this proportional thinking. Now, in relation to the limits of the sequence noted: 1)time sufficient to propose a higher number of problem conditions to be carried by students who may have been a trigger of construction have not through the proportional multiplication;2)the distant proposition situations of assimilation schemes (interpretation) of the students, which may have caused certain imbalance in them, preventing them from thinking about the problem situation;3)the rapid passage of...

This study describes how adult and teacher-centered rationale, which has been ruling school relations for a long time, might be a threat to didactics and its methodologies, especially when it comes to teaching and learning package. The theoretical framework of this study is based on Dewey and Peirce pragmatic views, founding the languages analysis, which are interwoven in the content design. Some tasks from a 4th grade elementary school package sold nationally, related to Geography and Mathematics subjects were examined. It is possible to assert that the child real life learning experiences was poorly considered, which partly explains the lack of interest of most children in pedagogical-scientific discourses as they are presented on their books. As a possible answer regarding that issue, the encounter between teacher and learner subjectivities is proposed.
