Ecological phytochemistry of Cerrado (Brazilian savanna) plants

The Cerrado (the Brazilian savanna) is one of the vegetation formations of great biodiversity in Brazil and it has experienced strong deforestation and fragmentation. The Cerrado must contain at least 12,000 higher plant species.We discuss the ecological relevance of phytochemical studies carried out on plants from the Cerrado, including examples of phytotoxicity, antifungal, insecticidal and antibacterial activities. The results have been classified according to activity and plant family. The most active compounds have been highlighted and other activities are discussed. A large number of complex biochemical interactions occur in this system. However, only a small fraction of the species has been studied from the phytochemical viewpoint to identify the metabolites responsible for these interactions

Psicologia e atenção básica: vivências de estagiários na Estratégia de Saúde da Família Psychology and basic attention: experiences of trainees in Family Health Strategy

Trata-se de uma pesquisa qualitativa de inspiração teórica humanista acerca das vivências de estagiários do curso de graduação em psicologia da PUC-Campinas na área da Saúde/Clínica, na atenção básica em saúde pública, como participantes de equipes de saúde da família. Participaram seis estagiários do último ano do curso, alocados em dois Centros de Saúde-Escola da região Noroeste de Campinas. A metodologia utilizada foi de cunho etnográfico. O processo para composição dos dados foi produzido em dois momentos: a) registro semanal em diário pessoal de cada estagiário, durante cinco meses; b) entrevistas individuais, semidirigidas, ao final do período letivo. Estes dados foram analisados a partir de uma leitura fenomenológica. Encontraram-se fases evolutivas no processo de formação do estagiário. Inicialmente, a experiência foi vivenciada com surpresa e estranhamento, gerando sentimentos contraditórios de inadequação frente à inexperiência para o trabalho em equipe. No entanto, por terem sido acolhidos e compreendidos pela equipe, ocorreu uma transformação de natureza pessoal e formativa, considerada muito enriquecedora, simbolizada como vivência singular de pertencimento, motivando esforços para prática clínica integradora e criativa.<br>This study shows a qualitative research based on a humanist theory in relation to the experiences of trainees from the psychology course of PUC-Campinas, that are participating in family health teams in the areas of Health/Clinic and basic attention in public health. The participants were six trainees in the last year of the course and located in two Health-School Centers in the Northwest region of Campinas. The methodology used was an ethnographic view. The processes of data composition were produced in two different moments: a) by weekly register on the trainee's personal diary during five months; b) semi-directed individual interviews at the end of the term. These data were analyzed according to a phenomenological reading. It was found evolutive stages in the process of the trainee formation. Initially, the experience was lived with surprise and strangeness, resulting in contradictory feelings of innapropriation to their inexperience to work in teams. On the other hand, because they were well received by the group, there was a personal transformation considered to be very enriching, symbolized as a single felling of belonging, motivating efforts to a creative and integrating clinic practice
