    The action of extracts from the stem, leaves, and fruit of Jatropha gossypiifolia on Biomphalaria glabrata was studied by analyzing survival, feeding capacity and oviposition ability. The extracts were obtained by macerating the plant parts in 92% ethanol, which were then evaporated until a dry residue was obtained and phytochemically studied. The molluscicidal activity on B. glabrata was investigated using the procedures recommended by WHO (1965). The amount of food ingested and oviposition were measured during each experiment. The extract of leaves from J. gossypiifolia was shown to be a strong molluscicidal agent, causing 100% mortality of B. glabrata, even in the lowest concentration tested, of 25 ppm. Regarding the fruit extract, there was variation in the mortality, depending on the concentration used (100, 75, 50 and 25 ppm). The snails that were in contact with the fruit extract had significant reduction in feeding and number of embryos in comparison to the control. The stem extract did not present molluscicidal activity nor had any influence on the feeding and oviposition abilities of B. glabrata, in the concentrations tested. In conclusion, the extracts of leaves and fruits of J. gossypiifolia investigated in this work show molluscicidal effect and may be sources of useful compounds for the schistosomiasis control

    An enchanted modernity: Making sense of Latin America’s religious landscape

    This is an interpretative, critical, and selective review of scholarly contributions that explore Latin America’s religious landscape. We present data, both qualitative and quantitative, from Latin America and analyze the explanations given to make sense of it. After assessing the literature that uses either secularization theory or the “religious economy” approach, we study explanations that highlight a Latin American style of “popular religiosity.” These three models, in different ways, put the emphasis on religious institutions—their vitality, commands, competition, and authority. We propose, instead, a focus on the religious practices of regular believers. We speculate that embarking from that focus, the idea of an “enchanted modernity” will help make sense of Latin America’s religious landscape. Nuanced elucidation of Latin America’s religious particularities will situate them in dialogue with other regions of the world, like western Europe and the United States, while also acknowledging the fact that Latin America is experiencing a modernization process distinct from the North Atlantic one.Fil: Morello SJ, Gustavo.
