A identidade fraturada no processo enunciativo de Grace Passô

O processo enunciativo da dramaturga Grace Passô propõe uma análise da necropolítica entranhada no corpo-feminino-negro de sua protagonista da peça de teatro "Vaga carne". Por meio da construção e desconstrução da escrita, permite-se uma reflexão sobre uma subjetividade negra em vivência a partir dos significados costurados pelos discursos políticos-culturais-sociais-literários que confrontam a camada dirigente.The enunciative process of the playwright Grace Passô proposes an analysis of the necropolitics ingrained in the black-female-body of her protagonist of the play "Vaga carne". Through the construction and deconstruction of writing, it is possible to reflect on a black subjectivity in experience from the meanings sewn by the political-cultural-social-literary discourses that confront the ruling layer.

Hélio Serejo e Brô MC’s: as poéticas do oeste em um novo projeto de nação

In this year that follows the  Centenary of the Week of 1922, we propose a  study on the need to expand concepts of modernity and national identity. From this perspective, it is worth analyzing certain hybrid poetics – such as the narratives of Hélio Serejo and the poetry of rappers Brô MC's – coming from historically invisible regions, engaged in the defense of new aesthetic codes and knowledge for the construction of a model of Brazilianness free from colonial violence once legitimized in this country.Neste ano que sucede o Centenário da Semana de 22, propomos um estudo sobre a necessidade de expansão dos conceitos de modernidade, literatura e identidade nacional. Nessa perspectiva, convém analisar determinadas poéticas híbridas – como as narrativas de Hélio Serejo e a poesia dos rappers Brô MC’s – advindas de regiões historicamente invisibilizadas, engajadas na defesa de novos códigos estéticos e saberes para a construção de um modelo de brasilidade livre da violência colonial outrora legitimada no território nacional

O nível de concentração de alumínio na água como fator de risco para o desenvolvimento da doença de alzheimer / The aluminum concentration level in water as a risk factor for the development of alzheimer's disease

OBJETIVO: Avaliar sobre as concentrações do Alumínio (Al) na água como um fator de risco para o desenvolvimento da Doença de Alzheimer (DA). METODOLOGIA: O rastreio dos artigos do presente estudo, foi realizado nas bases de dados BVS e PUBMED utilizando a metodologia Population – Intervention – Comparison – Outcome. A pesquisa ocorreu a partir de duas estratégias de busca com descritores pertinentes à DA, água e o alumínio. Foram considerados elegíveis os estudos dos tipos ensaios clínicos controlados randomizados, experimentais, casos controle que discorrem sobre Al como um fator de risco para o desenvolvimento da DA na ingestão de água; além dos artigos em inglês, português, espanhol e francês dos últimos 28 anos. Os artigos que não apresentavam critérios de elegibilidade foram as pesquisas que não tinham enfoque de como o indivíduo era exposto ao Al, artigos de revisão e resumos. RESULTADOS: Foram selecionados 13 artigos, dos quais 9 eram estudos do tipo casos e controle, 2 ensaios clínicos controlados e 2 estudos experimentais. CONCLUSÃO: As concentrações de alumínio na água podem ser um fator de risco para o desenvolvimento da DA. Porém, o tempo de exposição, a origem da água e a presença de outras substâncias também podem influenciar

Evidence of multidecadal salinity variability in the eastern tropical North Atlantic

The definitive version was published in Paleoceanography 21 (2006): PA3010, doi:10.1029/2005PA001257.Ocean circulation and global climate are strongly influenced by seawater density, which is itself controlled by salinity and temperature. Although adequate instrumental sea-surface temperature (SST) records exist for most of the surface oceans over the past 100-150 years, records of salinity really only exist for the last 40-50 years. Here we show that longer proxy records from corals (Siderastrea radians) in the eastern tropical North Atlantic are dominated by multi-decadal variations in salinity which are correlated with the relationship between SST and the North Atlantic Oscillation (NAO) over the course of the 20th century. The data reveal an increase in eastern tropical North Atlantic salinity of +0.5 psu between about 1950-1990. Rather than a monotonic secular increase, as indicated by some instrumental records, the pre-instrumental coral proxy records presented here suggest that salinity in the tropical North Atlantic is periodic on a decadal to multi-decadal scale

β-globin haplotypes in normal and hemoglobinopathic individuals from Reconcavo Baiano, State of Bahia, Brazil

Five restriction site polymorphisms in the β-globin gene cluster (HincII-5‘ ε, HindIII-G γ, HindIII-A γ, HincII- ψβ1 and HincII-3‘ ψβ1) were analyzed in three populations (n = 114) from Reconcavo Baiano, State of Bahia, Brazil. The groups included two urban populations from the towns of Cachoeira and Maragojipe and one rural Afro-descendant population, known as the “quilombo community”, from Cachoeira municipality. The number of haplotypes found in the populations ranged from 10 to 13, which indicated higher diversity than in the parental populations. The haplotypes 2 (+ - - - -), 3 (- - - - +), 4 (- + - - +) and 6 (- + + - +) on the βA chromosomes were the most common, and two haplotypes, 9 (- + + + +) and 14 (+ + - - +), were found exclusively in the Maragojipe population. The other haplotypes (1, 5, 9, 11, 12, 13, 14 and 16) had lower frequencies. Restriction site analysis and the derived haplotypes indicated homogeneity among the populations. Thirty-two individuals with hemoglobinopathies (17 sickle cell disease, 12 HbSC disease and 3 HbCC disease) were also analyzed. The haplotype frequencies of these patients differed significantly from those of the general population. In the sickle cell disease subgroup, the predominant haplotypes were BEN (Benin) and CAR (Central African Republic), with frequencies of 52.9% and 32.4%, respectively. The high frequency of the BEN haplotype agreed with the historical origin of the afro-descendant population in the state of Bahia. However, this frequency differed from that of Salvador, the state capital, where the CAR and BEN haplotypes have similar frequencies, probably as a consequence of domestic slave trade and subsequent internal migrations to other regions of Brazil
