Consumo de álcool e risco para doença coronariana na região metropolitana de São Paulo: uma análise do Projeto GENACIS

OBJETIVOS: Examinar a associação entre consumo de álcool e risco para doença coronariana em amostra populacional. MÉTODOS: Estudo transversal, de base populacional, conduzido de janeiro/2006 a junho/2007, na região metropolitana de São Paulo, como parte do estudo internacional (Gender, Alcohol, and Culture: an International Study). Os sujeitos (1.501, sendo 609 homens e 892 mulheres) eram residentes da região metropolitana de São Paulo, tinham 30 anos ou mais de idade e foram selecionados aleatoriamente, a partir de amostragem complexa por conglomerados. Todos os indivíduos consentiram em participar da pesquisa. A variável dependente foi risco cardíaco avaliado através do WHO Rose Angina Questionnaire. A análise multivariada consistiu em regressão logística, tendo sido realizado ajuste para uso de tabaco e índice de massa corpórea. RESULTADOS: A taxa de resposta foi 75%. Ser mulher, ter mais idade, ser negro, fumante e ter um índice de massa corpórea elevado, foram associados a maior risco para doença coronariana. Indivíduos que nunca beberam na vida (OR = 2,22) e ex-bebedores (OR = 2,42) tiveram maior risco de doença cardíaca do que aqueles que informaram beber até 19 g de álcool por dia, sem episódios de beber excessivo. Entre os que tiveram episódios de embriaguês observou-se uma tendência a maior risco (OR = 3,95, p = 0,09). CONCLUSÕES: Nossos achados sugerem um menor risco para doença coronariana entre os bebedores moderados. Destaca-se que os estudos que avaliam o impacto do álcool sobre doença cardíaca precisam identificar o padrão de uso de álcool dos sujeitos, visto que este aspecto pode modificar o risco. Políticas públicas são necessárias para reduzir o uso nocivo de álcool e a morbidade a ele relacionada no país.

Objetos de ensino: a renovação pedagógica e material da escola primária no Brasil, no século XX

This article aims at analyzing the role of the objects of learning in the propositions for innovation of primary schools during the 20th century, highlighting the changes in the composition of school subjects having in mind the objects that were introduced and marked out as relevant for school modernization and those that remained or were redefined in terms of their finality and uses. The examination of three significant moments of the implementation of innovations in the elementary school is intended: the modernization by the intuitive method at the turn of the century; the propositions of Escola Nova between the 1930s and the 1950s; and the renovation represented by educational technology in the 1960s and 1970s.

The Role of the (In)visible and the Secret in the Translation of Harryette Mullen s Muse & Drudge

This paper, based on Jacques Derrida’s thoughts in Des Tours of Babel, addresses the issue regarding the (in)visible in translation, by arguing that the latter, beyond the traditional conception of communication, produces a complex set of relations between the visible and the invisible, which highlights the values of the non-dit and the secret that take place in their relation to interpretation. This line of thought underpins the discussion of my translation of two poems from Muse & Drudge (1995), by the African-American poet Harryette Mullen, whose dense poetry displays un(expected) possibilities of meanings and associations that proliferate in translation. It is argued that every act of translation entails a relationship between that which is translated (and made visible or intelligible through this act) and that which remains invisible and secret by resisting a definitive translation, which, as such, requires further interpretations in search for intelligibility (or “visibility”). We analyze the extent to which such relation between the visible and the invisible takes part in the translation of the notion of blackness raised by Mullen’s poems and how her translated poetry dialogues with issues of reception in Brazilian culture.

Dilemas na tradução de Muse & Drudge (Musa E Mula), de Harryette Mullen: negritude, dissonância e miscigenação

This paper aims to discuss a project of translating part of the work Muse & Drudge, by the award-winning African-American poet Harryette Mullen, into Brazilian Portuguese, with focus on a single poem. In Muse & Drudge Mullen combines cultural critique with humor, lyricism and punning, which has unfolded the frontiers between cultural and racial identity, and has put into question the opposition between popular and high culture. This work analyzes to which extent the proposed translation produces a new set of intertextual relations that might culminate in “unexpected” meanings. It is a goal to understand how the effects of such “unexpected” meanings reveal the “encounter” between the so-called racial “black/white” dichotomy, predominant in the US culture, and the notion of “miscegenation” and “racial democracy” in Brazil.

A tradução de Invisible Man, de Ralph Ellison: o jogo entre racialidade e integracionismo

Relating the surface of a translated text to discourse is one of the focuses in the connection between Translation Studies and African- -American literature. In this respect, “Invisible Man”, by Ralph Ellison, and its Brazilian translation, by Márcia Serra, present themselves as material for analyzing contexts which evoke a sense of community and racial identity. Therefore, this paper centers precisely upon nuances in meaning of the linguistic displays of bonding and race. It could be noticed that these aspects were less marked in the translation, whereas the integrationist project featured in the novel was to a certain extent rewritten in words that called forth a sense of racial dichotomy. Thus, the translation displays at once the non-racialized perspective peculiar to the Brazilian view of race and assumptions in regard to the perspective of the African-American Other on race relations.

Growth of Candida species on complete dentures: effect of microwave disinfection

Microwave disinfection of complete dentures has been recommended to treat denture stomatitis in non-immune compromised patients. Oral candidiasis is a frequent manifestation of HIV infection. The objective of this study is to evaluate the effectiveness of microwave irradiation on the disinfection of complete dentures inoculated with American Type Culture Collection (ATCC) and HIV isolates of five species of Candida. Fifty dentures were made, sterilised and inoculated with the tested microorganisms (C. albicans, C. dubliniensis, C. krusei, C. glabrata and C. tropicalis). After incubation (37 degrees C/48 h), dentures were microwaved (650 W/3 min). Non-irradiated dentures were used as positive controls. Replicate aliquots of suspensions were plated at dilutions 10(-1) to 10(-4) and incubated (37 degrees C/48 h). Colony counts (cfu ml(-1)) were quantified. Dentures were also incubated at 37 degrees C for 7 days. Data were analysed with 2-way anova and Tukey HSD tests (alpha = 0.05). Dentures contaminated with all Candida species showed sterilisation after microwave irradiation. All control dentures showed microbial growth on the plates. The cfu ml(-1) for C. glabrata was higher than those of C. albicans, C. dubliniensis and C. tropicalis whereas the cfu ml(-1) for C. krusei was lower. The cfu ml(-1) for clinical isolates was higher than those of ATCC yeast. Microwave irradiation for 3 min at 650 W resulted in sterilisation of all complete dentures.

Clinical and histologic features of botryoid odontogenic cyst: A case report

Introduction. The lateral periodontal cyst, as the name implies, occurs on a lateral periodontal location and is of developmental origin, arising from cystic degeneration of clear cells of the dental lamina. A botryoid odontogenic cyst is considered to be a rare multilocular variant of a lateral periodontal cyst. Case presentation. We report the clinical and histopathologic features of a rare case of botryoid odontogenic cyst found in an edentulous area corresponding to the right lower canine of a 64-year-old African-American woman. A multilocular radiolucency was observed, and surgical removal of the lesion revealed a nodule of rubber-like consistency measuring about 1.5 cm in diameter. Cross-sectioning of the nodule showed that it consisted of various cystic compartments. Histologically, various voluminous periodic acid-Schiff-negative clear cells randomly distributed throughout the cystic epithelium were observed, as well as cell layers showing thickenings generally formed by oval, sometimes entangled plaques. The capsule consisted of fibrous connective tissue and showed rare and discrete foci of a perivascular mononuclear inflammatory infiltrate and reactive bone-tissue fragments. The final diagnosis was botryoid odontogenic cyst. Conclusion: We provide data that allow the reader to establish the differences between botryoid odontogenic cyst, glandular odontogenic cyst, and lateral periodontal cyst, helping with the differential diagnosis. The reader will have the opportunity to review botryoid odontogenic cyst clinical and histopathologic features, including treatment. © 2010 Farina et al; licensee BioMed Central Ltd.

A single multiplex SNaPshot reaction of 42 SNPs to classify admixture populations into mitochondrial DNA haplogroups

SNaPshot minisequencing reaction is in increasing use because of its fast detection of many polymorphisms in a single assay. In this work we described a highly sensitive single nucleotide polymorphisms (SNPs) typing method with detection of 42 mitochondrial DNA (mtDNA) SNPs in a single PCR and SNaPshot multiplex reaction in order to allow haplogroup classification in Latin American admixture population. We validated the panel typing 160 Brazilian individuals. DNA was extracted from blood spotted on filter paper using Chelex protocol. Forty SNPs were selected targeting haplogroup-specific mutations in Europeans, Africans and Asians (only precursors of Native Americans haplogroups A2, B2, C1, and D1) and two non-coding SNPs were chosen to increase the power of discrimination between individuals (SNPs positions 16,519 and 16,362). It was done using a modified version of a previously published multiplex SNaPshot minisequencing reaction established to resolve European haplogroups, adding SNPs targeting Africans (L0, L1, L2, L3, and L*) and Asians (A, B, C, and D) haplogroups based on SNPs described at PhyloTree.org build 2. PCR primers were designed using PerlPrimer software and checked with the Autodimer program. Thirty-three primer-pairs were used to amplify 42 SNPs. Using this panel, we were able to successfully classify 160 individuals into their correct haplogroups. Complete SNP profiles were obtained from 10. pg of total DNA. We conclude that it is possible to build and genotype more than 40 mtDNA SNPs in a single multiplex PCR and SNaPshot reaction, with sensitivity and reliability, resolving haplogroup classification in admixture populations. © 2011.

European Ancestry Predominates in Neuromyelitis Optica and Multiple Sclerosis Patients from Brazil

Background: Neuromyelitis optica (NMO) is considered relatively more common in non-Whites, whereas multiple sclerosis (MS) presents a high prevalence rate, particularly in Whites from Western countries populations. However, no study has used ancestry informative markers (AIMs) to estimate the genetic ancestry contribution to NMO patients. Methods: Twelve AIMs were selected based on the large allele frequency differences among European, African, and Amerindian populations, in order to investigate the genetic contribution of each ancestral group in 236 patients with MS and NMO, diagnosed using the McDonald and Wingerchuck criteria, respectively. All 128 MS patients were recruited at the Faculty of Medicine of Ribeirão Preto (MS-RP), Southeastern Brazil, as well as 108 healthy bone marrow donors considered as healthy controls. A total of 108 NMO patients were recruited from five Neurology centers from different Brazilian regions, including Ribeirão Preto (NMO-RP). Principal Findings: European ancestry contribution was higher in MS-RP than in NMO-RP (78.5% vs. 68.7%) patients. In contrast, African ancestry estimates were higher in NMO-RP than in MS-RP (20.5% vs. 12.5%) patients. Moreover, principal component analyses showed that groups of NMO patients from different Brazilian regions were clustered close to the European ancestral population. Conclusions: Our findings demonstrate that European genetic contribution predominates in NMO and MS patients from Brazil. © 2013 Brum et al.
