Caracterização do Xote e do Baião dançados no interior do Estado de São Paulo

Ballroom dance and Forro are part of Brazilian culture, and Xote and Baiao are part of Forro. The aim of this study was to diagramate the dances Xote and Baiao they are danced inside São Paulo State and to describe rhythmly these movements. It was observed and filmed several college couples dancing Xote and Baiao for analysis and description of the movements of the dances, by a discursive way and by diagrams. It was identified two basic structures ("Lateral Basic Step" and "Forward and Back Basic Step"), and variation steps "Open" and "Change of places with Turn", very used by couples.

Os fios da trama: grandes temas da música popular tradicional brasileira

Nos cantos, danças e folguedos populares brasileiros, podemos encontrar um feixe de motivos entrelaçados, padrões multicores de um tecido de que conviria procurar e acompanhar cada um dos fios aí urdidos e tramados, agrupando-os segundo sua textura ou coloração. Essas diferentes linhas temáticas, os fios da trama das expressões artísticas e religiosas do povo brasileiro são o assunto deste artigo, que procura analisar formas culturais caracterizadas pela hibridação, as quais transitam muitas vezes na ambiguidade entre resistência e aceitação de um padrão cultural dominante. O dinamismo dos arranjos de um certo número de motivos condutores recorrentes no âmbito da cultura de tradição oral brasileira nos leva a especular sobre os processos de formação de suas práticas artísticas, bem como sobre sua circulação num país de dimensões continentais.

Isotopic evidence for the late Brasiliano (500-550 Ma) ore-forming mineralization of the Araes gold deposit, Brazil

The Araes gold deposit, located in eastern Mato Grosso State, central Brazil, is hosted in Neoproterozoic volcanosedimentary rocks of the Paraguay belt, which formed during collision of the Amazonian craton and the Rio Apa block. Ar-40/Ar-39 geochronology and Pb and S isotopic analyses constrain the timing and sources of mineralization. Three biotite flakes from two samples of metavolcanic host rock yield Ar-40/Ar-39 plateau ages between 5941 and 531 Ma, interpreted as cooling ages following regional metamorphism. Clay minerals from a hydrothermal alteration zone yield an Ar-40/Ar-39 integrated age of 503 +/- 3 Ma. Galena grains from ore-bearing veins yield values of Pb-206/(204)pb from 17.952 to 18.383, Pb-207/Pb-204 from 15.156 to 15.811, and Pb-208/Pb-204 from 38.072 to 39.681. Pyrite grains from ore-bearing veins yield values of Pb-206/Pb-204 from 18.037 to 18.202, Pb-207/Pb-204 from 15.744 to 15.901., and Pb-208/(204)pb from 38.338 to 38.800. Pb isotope variations may be explained in terms of mixing a less radiogenic lead component (mu similar to 8.4) from mafic and ultramafic basement host-rocks (Nova Xavantina metavolcanosedimentary rocks) and a more radiogenic lead component (mu similar to 9.2) probably derived from supracrustal rocks (Cuiaba sedimentary groups). Sulfur isotope compositions are homogeneous, with delta S-34 values ranging from -1.1 parts per thousand to 0.9 parts per thousand (galena) and -0.7 parts per thousand to 0.9 parts per thousand (pyrite), suggesting a mantle-derived reservoir for the mineralizing solutions. Based on the Ar, Pb, and S isotope data, we suggest that the precious metals were remobilized from metavolcanic host rocks by hydrothermal solutions during Brasilide-Panafrican regional metamorphism. The Arabs gold deposit probably formed during a late stage of the orogeny, coeval with other mineralization events in the Paraguay Belt.

A review of antifertility folkloric plants tested in laboratory animals

The use of natural active principals is widespread among a great proportion of the rural population, or by people who do not have easy access to medical assistance. These active principles are used as food or medicines, and even for purposes of contraception. It becomes necessary to establish a relationship between the folklore habits and current information on the nature of anti-fertility substances, and knowledge of their mechanisms. Anti-fertility agents may exert their actions in a number of areas, (hypothalamus, anterior pituitary, oviduct, uterus, and vagina), inhibiting synthesis and/or liberation of hormones (follicle-stimulating, luteinizing, and steroid hormones), ovulation, ovum transportation, and implantation process. Therefore, a review of literature was carried out, including of several plants used by women as abortifacient and anti-fertility agents to compare their effects with those obtained among laboratory animals.

Gramsci e a emancipação do subalterno

In his Prison Notebooks, Gramsci worked with the notion of subaltern classes and groups, a concept that has been incorporated by the Social Sciences and current Historiography. Correlatedly, problems of common sense, folklore and religion are presented. It is important to raise the question of the theoretical and political implications of Gramsci's elaborations, contextualizing them within the entirety of his theoretical and political production, even if only to contest the common uses of the concept and their real relationship to Gramsci, or to examine to what extent this author can be considered relevant for interpretations of the conditions of social struggle in contemporary capitalism. © 2008 Revista de Sociologia e Política.

Antioxidant and cytotoxic effects of crude extract, fractions and 4-nerolidylcathecol from aerial parts of pothomorphe umbellata L. (Piperaceae)

The crude ethanolic extract from aerial parts of Pothomorphe umbellata L. (Piperaceae) and fractions obtained by partitions sequentially among water-methanol, methylene chloride, and ethyl acetate, as well as the major constituent, 4-nerolidylcatechol, were, respectively, evaluated and evidenced for antioxidant and cytotoxic effects through fluorometric microplate and microculture tetrazolium assays in HL-60 cells. The crude ethanolic extract demonstrated the preeminent antioxidant activity (IC50 = 1.2 μg/mL) against exogenous cytoplasmic reactive oxygen species, followed by the water-methanolic (IC50 = 4.5 μg/mL), methylene chloride (IC 50 = 5.9 g/mL), ethyl acetate (IC50 = 8.0 g/mL), 4-nerolidylcatechol (IC50 = 8.6 g/mL), and the sterol fractions (IC50 > 12.5 μg/mL). Vitamin C, the positive control used in this assay, presented IC50 value equivalent to 1.7 μg/mL. 4-Nerolidylcatechol (IC50 = 0.4 μg/mL) and methylene chloride fraction (IC50 = 2.3 μg/mL) presented considerable cytotoxicity probably because of the presence of an o-quinone, an auto-oxidation by product of the catechol. Polar compounds, present in the ethanol extract, appear to increase the solubility and stability of the major active constituent, acting synergistically with 4-nerolidylcatechol, improving its pharmacokinetic parameters and increasing significantly its antioxidant activity which, in turn, suggests that the aqueous-ethanolic extract, used in folklore medicine, is safe and effective. © 2013 Andrey P.
