O presente trabalho verificou como o jornalismo pode ser parceiro e fonte para a história por meio da reprodução e análise dos fatos político-econômicos brasileiros nas páginas dos jornais impressos diários. Nessa perspectiva, as colunas escritas nos últimos 25 anos (1983-2009) por Janio de Freitas, no jornal Folha de S.Paulo, significam interpretação e análise dessa história. Trata-se, portanto, de uma pesquisa qualitativa e está ancorada nos Estudos Culturais. O corpus desta pesquisa é composto de um recorte de 47 comentários sobre as Diretas Já , de janeiro até abril de 1984, período em que ocorreram as principais mobilizações da sociedade civil pela eleição direta para a Presidência da República e culminou com a votação e a rejeição da emenda Dante de Oliveira pelo Congresso Nacional. No desenvolvimento do trabalho foram utilizadas as ferramentas da Análise de Conteúdo a partir das categorias analíticas criadas Personagens, Votação da Emenda Dante de Oliveira e Movimento Diretas Já nas ruas , para descrever o conteúdo textual das colunas. Para que se pudesse efetuar uma análise aprofundada do corpus da pesquisa foi utilizado o referencial teórico da ACD Análise Crítica do Discurso em nove das 47 colunas selecionadas. O critério de escolha para essas colunas foi a identificação daquelas que no título já traziam uma referência explícita à Campanha pelas Diretas Já , Às mobilizações nas ruas , A votação da emenda Dante de Oliveira , Ao processo de sucessão presidencial ou as que tinham o seu conteúdo integral sobre um dos temas. Este estudo constata a hipótese de que o jornalista é um historiador do cotidiano e que é possível fazer uma leitura da história da Campanha das Diretas Já por meio das colunas de Janio de Freitas. Ao tecer em suas colunas o cenário da época, desnuda para a história e para os historiadores o xadrez político personagens, acordos políticos, votação da emenda e a campanha nas ruas que envolveu o processo. Dessa forma, a partir de suas lentes, oferece elementos para a construção da memória coletiva sobre esse período da história brasileira.(AU)

In recent decades, the collective leadership of the Solidary Economical Enterprises (ESS) that are active in providing collection and recycling services, has been presented as a proposal for the organization of urban space with the creation of new enterprises and solidarity production chains. Are activities that have gained a new stimulus to the creation of the National Secretariat of Solidarity Economy and the National Policy on Solid Waste that assigned a leading role in these social actors. These experiences contribute to building a participatory development path, resembling with the pluralistic perspective of development of the Indian economist Amartya Sen, that goes beyond the simplistic design of the increased income, focusing on the process of expanding freedoms that people enjoy. The aim of this work is to situate the perspective of endogenous development with the Collection Services segment and Material Recycling in the field of Solidarity Economy, through the analysis of the experience of the Cooperative of Selective Collection and Recycling Friends of the planet, located in the municipality of Lauro to Freitas - BA, from 2004 to 2013. for this the following procedures were adopted: analysis of the main contributions of the international literature on the phenomenon of pluriactivity; review of national literature that analyzes the emergence and evolution of the projects of solidarity economy in Brazil; bibliographical and documentary research; and socio-economic evaluation of the EES. The guiding problem of this work, understandably, is: what is the meaning of endogenous perspective with the Materials Collection and Recycling Services segment in the field of Solidarity Economy? It starts with the hypothesis that the development of these practices requires an environment that removes the main sources of deprivation involving the conditions of existence of these enterprises. The results show that not enough development to be built with the participation of social actors, but there are minimally necessary conditions for such experiences can take hold in order to achieve their goals. Thus, not only is it a strictly economic issue, but requires political actions for a process of social transformation.

Hancornia speciosa Gomes (Apocynaceae), popularly known as ‘mangabeira’, has been used in folk medicine to treat inflammatory disorders, hypertension, dermatitis, diabetes, liver diseases and stomach disorders. Regarding the Hancornia speciosa fruits, the ethnobotany indicates its use especially for treating inflammation and tuberculosis. However, no study has been done so far to prove such biological activities. The objective was evaluation anti-inflammatory activity from the fruits of Hancornia speciosa Gomes (mangabeira). Aqueous extract was prepared by decoction, subsequently submitted the liquid-liquid fractionation. The secondary metabolites were identified by high performance liquid chromatography coupled with detector diode array (HPLC-DAD) and liquid chromatography diode array detector coupled with mass spectrometry (LC-DAD-MS). The anti-inflammatory properties of the aqueous extract, dichloromethane (CH2Cl2), ethyl acetate (EtOAc) and n-butanol (n-BuOH) fractions of the fruits from H. speciosa, as well as rutin and chlorogenic acid were investigated using in vitro and in vivo models. In vivo tests comprised the xylene-induced ear edema that was measured the formation of edema, carrageenan-induced peritonitis was evaluated the total leukocytes at 4h and zymosan-induced air pouch was measured the total leukocytes and differential cell count at 6, 24 and 48 hours, whereas in vitro tests were evaluated levels of cytokines IL-1β, IL-6, IL-12 and TNF-α using ELISA obtained of carrageenan-induced peritonitis model. The results showed the presence of rutin and chlorogenic acid were detected in the aqueous extract from H. speciosa fruits by HPLC-DAD and LC-DAD-ME. Furthermore, the aqueous extracts and fractions, as well as rutin and chlorogenic acid significantly inhibited the xilol-induced ear edema and reduced cell migration in the animal models such as carrageenan-induced peritonitis and zymosan-induced air pouch. In addition, reduced levels of cytokines IL-1β, IL-6, IL-12 and TNF-α were observed. This is the first study that demonstrated the anti-inflammatory effect of aqueous extract from Hancornia speciosa fruits against different inflammatory agents in animal models, suggesting that their bioactive molecules, especially rutin and chlorogenic acid contributing, at least in part, to the anti-inflammatory effect of aqueous extract. These findings support the widespread use of Hancornia speciosa in popular medicine and demonstrate that this aqueous extract has therapeutic potential for the development of a herbal drugs with anti-inflammatory properties.

Accidents caused by venomous animals represents a significant and serious public health problem in certain regions of Brazil, as well as in other parts of the world by the frequency with which they occur and the mortality they cause. The use of plant extracts as an antidote for poisoning cases is an ancient practice used in many communities that have no access to antivenom. Medicinal plants represent an important source of obtaining bioactive compounds able to assist directly in the treatment of poisoning or indirectly supplementing serum therapy currently used. The aim of this study was to evaluate the effect of extracts, fractions and isolated compounds from M. tenuiflora and H. speciosa in the inflammatory process induced by carrageenan and the venom of B. jararaca and T. serrulatus. The results showed that both M. tenuiflora and H. speciosa were capable of inhibiting cell migration and cytokines levels in peritonitis induced by carrageenin and venom of T. serrulatus. In poisoning by B. jararaca model, mice treated with the plants in studies decreased the leukocyte influx into the peritoneal cavity. Finally the M. tenuiflora and H. speciosa had antiphlogistic activity, reducing edema formation and exerted inhibitory action of leukocyte migration in local inflammation induced by the venom of B. jararaca. Through of Thin Layer Chromatography (TLC) analysis was possible identified the presence of flavonoids ,saponins and/or terpenes in aqueous extract of M. tenuiflora. By High Performance Liquid Chromatography analysis, it was possible to identify the presence of rutin and chlorogenic acid in aqueous extract of H. speciosa. We conclude that the administration of extracts, fractions and isolated compounds of H. speciosa and M. tenuiflora resulted in inhibition of the inflammatory process in different experimental models. This study demonstrates for the first time the effect of M. tenuiflora and H. speciosa in inhibition of the inflammation caused by B. jararaca and T. serrulatus venom.

The classical treatment for congenital toxoplasmosis is based on combination of sulfadiazine and pyrimethamine plus folinic acid. Due to teratogenic effects and bone marrow suppression caused by pyrimethamine, the establishment of new therapeutic targets is indispensable to minimize the undesirable effects and improve the control of the infection. Previous studies demonstrated that enrofloxacin and toltrazuril were able to control the infection triggered by Neospora caninum and Toxoplasma gondii. Therefore, the aim of this present study was evaluate the efficacy of enrofloxacin and toltrazuril in the control of T. gondii proliferation in human trophoblast cells (BeWo lineage) and in human villous explants from third trimester. BeWo cells and villous were treated with several concentrations of enrofloxacin, toltrazuril, sulfadiazine, pyrimethamine or association (sulfadiazine + pyrimethamine) in other to verify their viability by MTT or LDH assay, respectively. Next, BeWo cells were infected with T. gondii RH (2F1 clone) or ME49 strain, whereas villous were infected only with RH strain (2F1 clone), after, both cells and villous were treated or not with the same antibiotics and analyzed to T. gondii intracellular proliferation by beta-galactosidase assay (for RH strain) or blue toluidine staining (for ME49 strain). ELISA was performed in the supernatant to evaluate the cytokine profile. Enrofloxacin and toltrazuril did not change strongly the viability in cells and villous. Furthermore, the drugs decreased the parasite intracellular proliferation regardless T. gondii strain in BeWo cells and villous explants when compared to untreated and infected conditions. In BeWo cells infected by RH, enrofloxacin induced high levels of IL-6 low levels of MIF, while both cytokines were upregulated by enrofloxacin and toltrazuril in BeWo cells infected by ME49 strain. Additionally, in villous explantes, enrofloxacin induced high MIF production. Thus, enrofloxacin and toltrazuril were able to control the parasitism in BeWo cells and villous explants, and probably it occurs by modulation of immune response in these cells or tissues and direct action on parasite, but future experiments are necessary to verify this hypothesis.

As viagens ocupam uma dimensão muito relevante na obra de Sena Freitas por terem sido objeto de descrições, em que, sob a forma de relatos ou de cartas, o autor deu a conhecer ao público leitor muitas das suas impressões da paisagem, do património e do estilo de vida dos países e cidades que visitou. Propomos centrar a atenção no relato das viagens em que o autor projeta muitas das suas ideias sobre os mais variados assuntos, desde a experiência missionária, no Brasil, até às suas conceções sobre a importância da ciência na formação dos jovens e do clero, as condições sociais e políticas dos operários, a importância social da religião e da tolerância religiosa, a par da exaltação da natureza, em que a sua ilha de S. Miguel não tem paralelo. Começaremos, no entanto, a nossa exposição, apresentando, em traços gerais, alguns aspetos da sua vida, que repartiu em grande parte entre Portugal e o Brasil, o que servirá para enquadrar o nosso propósito.

O Programa Saúde na Escola (PSE) resulta do trabalho integrado entre o Ministério da Saúde e o Ministério da Educação, propondo uma política intersetorial entre eles, na perspectiva da atenção integral (prevenção, promoção e atenção) à saúde do escolar. A autora, graduada em enfermagem pela Faculdade de Macapá – FAMA, foi alocada na Secretaria Municipal de Saúde – SEMSA, no matricial do Programa Saúde na Escola – PSE, na coordenação do programa. Esse tema foi escolhido porque como a autora não está alocada dentro da UBS e sim na SEMSA, no matricial do PSE, ou seja, na coordenação, tornou-se de grande conveniência realizar assim o projeto. A mesma escolheu a Escola de Ensino Fundamental Mãe Angélica para realizar a intervenção, com 224 alunos pactuados. A meta era alcançar 50% dos escolares em cada ação prevista, logo se alcançou muito mais que isso, ou seja, 70, 80 e até 90% em algumas ações. A intervenção deu bons resultados, se atingiu a meta determinada para a intervenção na maioria das ações. Alguns indicadores como os exclusivos para os escolares de 12 a 14 anos, não foram trabalhados. Enfim de 100% de satisfação do trabalho realizado, foram atingidos 80%. A intervenção mostrou que é possível realizar um bom trabalho dentro da escola, basta ter a integração da equipe da Estratégia Saúde da Família – ESF com a escola e pais de alunos.
