ORLANDO COSTAS: ENSAIOS NO CAMINHO PARA UMA PASTORAL EVANGÉLICA LATINO-AMERICANA

Nesta pesquisa se propõe analisar a pastoral evangélica latino-americana elaborada por Orlando Costas. Teólogo pastoralista, missiólogo e de origem porto-riquenha, Costas elaborou método e metodologia de pastoral a partir de sua confissão religiosa evangelical em diálogo ecumênico e em consonância crítica com a situação política, econômica, social e religiosa de Porto Rico e da América Latina. Costas, juntamente com Emilio Castro, foi um dos primeiros a lançar as bases para uma pastoral evangélica visando ao homem latino-americano. Criticou o modelo da teologia pastoral norte-atlântica centrada no pastor com sujeito da ação pastoral da igreja alegando ser; repetitiva, profissional e eclesiocêntrica. A pesquisa foi realizada em três passos, que se realizam nos capítulos um, dois e três, respectivamente, compreender o contexto político, econômico, social e religioso da vida de Orlando Costas a partir de Porto Rico, suas experiências de conversão-ruptura dentro da sua tradição religiosa e a nova percepção pastoral; analisar o desenvolvimento histórico teológico da pastoral evangélica, ou seja, os movimentos, conferências, instituições e teólogos que influenciaram o pensamento de Costas; e, apresentar os fundamentos missiológicos e teológicos da pastoral evangélica, em que se demonstra que a pastoral de Costas é missiológico-pastoral, pois assume a missio Dei como princípio arquitetônico e a pastoral como princípio hermenêutico para a ação missional e pastoral. Conclui-se que a proposta de Costas é de uma pastoral evangélica e ecumênica, contextual e autóctone, dentro e fora da igreja.(AU)

Avaliação dos efeitos tóxicos in vitro e in vivo do extrato hidroetanólico dos frutos de Genipa americana L. (Rubiaceae) em camundongos Swiss

The therapeutic use of medicinal plants has contributed since antiquity in a beneficial way for health. However, many species lacks of scientific evidence which provide basis for their use in therapeutic practice. In this context is the Genipa americana L. species (Rubiaceae), popularly known as jenipapo and used to treat syfilis, ulcer and hemorrhagic disturbs. It's also used against bruising, as tonic and as aphrodisiac. Due this species lacks toxicological studies, the aim of this study was to evaluate the toxicity in vivo (acute and sub-chronic toxicity) and in vitro (cytotoxicity) of the hydroethanolic extract from G. americana fruits. The hydroethanolic extract of G. americana fruits was prepared by maceration. A preliminary phytochemical analysis was performed to assess the presence of secondary metabolites in the extract. The cytotoxicity study of the extract (0.1, 1.0, 10, 100 and 1000 mg / 100 ul) were performed against normal cells (3T3) and tumor (786-0, HepG2 and B16), analyzed by the MTT assay. To evaluate the acute (single dose of 2000 mg / Kg) and subchronic (100, 500 and 1000 mg / kg for 30 days) toxicity Swiss mice of both sexes were used. At the end of the experiment, blood samples and organs were collected for analysis. Data between groups were compared by t test or ANOVA with Dunnett's post-test with 5% significance level. The phytochemical study of the extracts mainly indicated the presence of iridoids. Results for cytotoxicity tests showed up to 70% inhibition of B16 cell line at a dose of 1000 mg / 100 ul, and up to 29% inhibition of 786-0 at a dose of 10 ug / 100 ul. The extract did not cause death in 3T3 and HepG2 cells. During the in vivo assays, there were no animal deaths. Analysis of blood samples revealed that the animals submitted to the evaluation of acute toxicity had changes in AST and ALT, and that the animals evaluated for subchronic toxicity showed changes in the relative wet weight of the kidney and plasma urea concentration. No differences were observed between groups on histopathological evaluation of the collected organs. Despite the changes found in the in vivo toxicity tests, using the criteria described by the OECD Guidelines, it is suggested that the hydroethanolic extract of the fruits of the G. americana is classified as low toxicity. The cytotoxicity of the extract suggests that they have potential against melanoma cell lines (B16).

El arte camaleónico de Marcos Irizarry: entre el modernismo europeo y la abstracción americana, (1950-1970)

Marcos Irizarry (Mayagüez, Puerto Rico 1936-San Juan, Puerto Rico 1995) es uno de los artistas plásticos puertorriqueños más destacados e influyentes que creó una de las obras gráficas y pictóricas abstractas más significativas en Puerto Rico y España. La presente investigación tiene como objetivo el estudio y análisis de la obra de Marcos Irizarry. El estudio de la obra de Marcos Irizarry es importante, ya que los trabajos y escritos realizados tanto en Puerto Rico como en España son limitados, y mayormente se basan en el contexto puertorriqueño. El objetivo de esta investigación es contribuir a la historia del arte de Puerto Rico, de modo que se fomente el estudio, y se logre un mayor entendimiento de la abstracción y de la extensa obra gráfica del artista puertorriqueño Marcos Irizarry, sobre todo el que se dio durante las décadas sugeridas y mostrar su trascendencia, su gran legado, su amplio alcance y reafirmar su carácter universal. La hipótesis fundamental de este trabajo se basa en que la obra del artista puertorriqueño, Marcos Irizarry posee características, estéticas, conceptos y rasgos que pueden responder a las estipuladas tanto por el informalismo europeo-español o por la abstracción americana-puertorriqueña. Se concluyó que la obra gráfica realizada entre finales de los cincuenta hasta finales de los setenta, cobra carácter distinto si se ve como parte del proceso estético español de la posguerra o si se la sitúa en el ámbito del arte puertorriqueño...
