Abstract This study aims model the distribution of meiofauna indicators in relation to environmental variables from the Santos Basin continental margin, SE Brazil, using machine learning techniques, to provide baseline information and foster future monitoring programs. A total of 100 sampling stations were distributed in eight transects and 11 isobaths (25 to 2,400 m) perpendicular to the coast. In each station, three replicates were sampled for meiofauna and 38 environmental parameters. A total of 28 meiofauna taxa were found, with a mean richness varying from 3 to 15 taxa per station. Meiofauna mean density varied between 55 and 2,001 ind. 10 cm-2. Density of meiofauna and its most frequent taxa (Nematoda, Copepoda, Kinorhyncha, and Polychaeta), and taxa richness were used as descriptors for the models. Meiofauna and nematode density showed the highest training and testing accuracies, with R² values above 0.74. Based on the distribution of meiofauna descriptors and their responses to environmental conditions, we suggest a mosaic of six benthic zones. The La Plata Plume zone and the Cabo Frio Upwelling zone are two of the most diverse and productive zones in the continental shelf, wich are separated by the less productive Central Continental Shelf zone. A fourth zone, with very low meiofauna densities, corresponds to the carbonated sediments of the shelf-break. The Upper and Mid-Slope is a narrow zone along the entire basin, with intermediate densities and small amounts of high-quality organic carbon. The largest, impoverished zone, the Lower Slope and Plateau comprises the deepest areas and the São Paulo Plateau. The study showed that, although some zones can be recognized by most meiofauna descriptors, others are better characterized by specific ones, implying that meiofauna indicators should be monitored concomitantly. We recommend the optimization of sampling design based on our model to reduce costs and increase our understanding of the system.

ABSTRACT Introduction: Oral lichen planus is a chronic inflammatory disease affecting the mucosa. Objective: To report a clinical case of oral lichen planus in gingiva whose removal was carried out by the de-epithelialization technique of the affected areas. Case report: A 56-year-old female patient presented white plaques upon clinical examination that could not be removed by scraping. The treatment plan involved a biopsy and lesion removal by de-epithelialization, procedure not described in the literature up to date. This technique consisted of the removal of the plaques with the epithelial tissue from the gingiva using a 15c blade, leaving the connective tissue exposed. Clinical follow-up was performed at 3 and 10 days, and at 2, 3 and 15 months. Conclusions: De-epithelialization was a resolutive esthetic intervention for the case presented.

RESUMEN Introducción: El liquen plano oral es una enfermedad inflamatoria crónica que afecta a la mucosa. Objetivo: Reportar un caso clínico de liquen plano oral en encía cuya extirpación se realizó mediante la técnica de desepitelización de las áreas afectadas. Reporte de caso: Una paciente de 56 años presentaba placas blancas en el examen clínico que no podían eliminarse con raspado. El plan de tratamiento consistió en una biopsia y extirpación de la lesión por desepitelización, procedimiento no descrito hasta la fecha en la literatura. Esta técnica consistió en la eliminación de las placas con el tejido epitelial de la encía utilizando una cuchilla de 15c, dejando expuesto el tejido conectivo. El seguimiento clínico se realizó a los 3 y 10 días, ya los 2, 3 y 15 meses. Conclusiones: La desepitelización fue una intervención estética resolutiva para el caso presentado.

O aumento gradual da participação da comunidade acadêmica da Fisioterapia nas edições do Congresso Brasileiro de Biomecânica (CBB) é notório. Os Anais do CBB passaram a ser importantes veículos para a divulgação científica em Fisioterapia no Brasil; porém, a caracterização dessa produção ainda não foi feita. O objetivo do presente estudo foi realizar um levantamento bibliográfico dos estudos em Fisioterapia publicados nas edições dos Anais do CBB, desde a primeira edição em 1992 (Anais do IV CBB) até a edição publicada em 2009 (Anais do XIII CBB), a fim de identificar quais especialidades da Fisioterapia têm aplicado o conhecimento em Biomecânica no contexto clínico e/ou científico, além de caracterizar o tipo de pesquisa que se tem desenvolvido. Seis revisores independentes levantaram os estudos pertencentes à área da Fisioterapia e coletaram informações de maneira padronizada através de questionários. Os resultados evidenciaram um grande crescimento da participação das diferentes áreas da Fisioterapia ao longo das dez edições do CBB. Embora os dados sejam positivos em relação à ampliação das pesquisas em Biomecânica, verificou-se uma carência da utilização dos recursos biomecânicos para avaliar efeitos de intervenções em pacientes. Dessa forma, recomenda-se que mais estudos sejam conduzidos em contextos clínicos e com acompanhamento longitudinal, de modo a ampliar a aplicação prática das ferramentas biomecânicas no campo da intervenção, bem como aperfeiçoar a avaliação em Fisioterapia.

The increasing presence of the Physical Therapy (PT) community in the Brazilian Congress of Biomechanics (CBB) is well known. The Proceedings of the CBB Congresses have turned to important vehicles to scientific publications in Physical Therapy, but the characteristics of these studies have not been focus of analysis. Thus, the purpose of this study was to identify the contribution of PT to the studies published in the Proceedings of the CBB Congresses, from the first edition in 1992 (Proceedings of the IV CBB) to the 2009 edition (Proceedings of the XIII CBB), in order to verify which subareas of expertise in PT are applying the biomechanical knowledge on clinical and/or scientific context and the kind of research being developed. Six independent reviewers collected data related to the PT production according to standardized questionnaires. The results evidenced that the area of PT has increased its publications along the ten CBB Proceedings. Despite positive findings, we noticed a lack of biomechanical studies aimed at investigating interventions in patients. Thus, we can suggest that clinical studies with a longitudinal design could be developed in order to improve the application of biomechanical tools in therapeutic settings and to contribute to evaluation procedures in PT.

OBJECTIVE: The present study evaluated the association between lactotransferrin (LTF) gene polymorphism (exon 2, A/G, Lys/Arg) and dental caries. MATERIAL AND METHODS: A convenience sample of 110 individuals, 12 years old, was divided into: group 1, 48 individuals without caries experience (DMFT=0), and group 2, 62 subjects with caries experience (DMFT>1). DNA was obtained from a mouthwash with 3% glucose solution, followed by a scrapping of the oral mucosa. After DNA purification, polymerase chain reaction (PCR), single strand conformation polymorphism (SSCP) was performed to access the study polymorphism. The LTF A/G (Lys/Arg) polymorphism had been previously reported as located in exon 1. RESULTS: Allele 1 of the study polymorphism was associated with low DMFT index and showed a protective effect against caries experience (OR=0.16, IC=0.03-0.76, p=0.01). CONCLUSIONS: Lactotransferrin A/G (exon 2, Lys/Arg) polymorphism was associated with susceptibility to dental caries in 12-year-old students.

A Revista Estudos Feministas (REF) é uma das mais importantes publicações sobre gênero e feminismo no Brasil. Este artigo descreve o perfil das autoras e dos temas dos artigos publicados na REF de 1992 até 2002. Foram analisados os títulos, os resumos e as palavras-chaves dos artigos avulsos e os temas dos dossiês, em um total de 20 editoriais, 105 artigos avulsos e 20 dossiês. A classificação e indexação temática do material seguiram o vocabulário controlado do "Tesauro para Estudos de Gênero e sobre Mulheres", da Fundação Carlos Chagas. Os resultados da análise mostram que 95% das autoras são mulheres e que 54% são oriundos das Ciências Sociais. Há artigos em todas as áreas temáticas previstas no Tesauro, exceto em "Ciência e Tecnologia" e "Educação", havendo uma concentração de publicações nas áreas temáticas "Ciências Sociais e Cultura" (26%), "Linguagem, Literatura, Religião e Filosofia" (17%) e "História e Mudança Social" (17%). Os assuntos mais discutidos foram nesta ordem: divisão sexual do trabalho, análise literária, reprodução e teoria feminista. A análise mostra ainda que o trabalho de pesquisa em gênero e feminismo é solitário, havendo poucos artigos em co-autoria (12%) e a metodologia de pesquisa preferencial é a qualitativa, em 92%. A freqüência com que a mesma autora publica na REF é bastante baixa, havendo uma alta rotatividade de autoras.. A expectativa é que os resultados desta análise facilitem a definição de prioridades temáticas, favoreçam a criação de estratégias de pesquisa em áreas pouco exploradas, cooperando para a consolidação do trabalho educativo e político da revista, o que fortalecerá os estudos e pesquisas em gênero e feminismo no Brasil.

Revista Estudos Feministas (REF) is one of the most important gender and feminist journals in Brazil. This article describes the author background and the subjects of the articles published in REF from 1992 to 2002. It was analysed the title, abstracts and keywords of the articles and the topics of the dossier, totalising 20 editorials, 105 articles and 20 dossiers. The classification and indexation of the material was guided by the controlled vocabulary of the "Tesauro para Estudos de Gênero e sobre Mulheres", from Fundação Carlos Chagas. The results show that 95% of the authors are women, and that 54% are from Socials Sciences. There are articles in all thematic areas suggested by the Tesauro except on "Science and Technology" and "Education", with a concentration on the following thematic areas: "Socials Sciences and Culture" (26%), "Language, Literature, Religion and Philosophy" (17%) and "History and Social Transformation" (17%). The most discussed topics were in this order: sexual division of work, literary analysis, reproduction, and feminist theory. The analysis of REF suggests that gender and feminist research is a solitary activity, with a few number of articles published in partnership. There is a strong preference for qualitative methodologies (92%). This article aims to facilitate the process of identification some marginal areas in the gender and feminist studies in Brazil, empowering the educational and political work of the journal.
