Murilo Rubião: enlaces eróticos, fantásticos e absurdos

The present research intends to propose a reading in a new dimension of the fantastic (weird) literature and, especially, of its Brazilian more representative author, Murilo Rubião. At the beginning with concepts and associations with the erotic, starting from the myth of Eros and Psique and developing relations with Georges Bataille's theory on the theme. Afterwards, other associations are made, now with relation to the own fantastic literature. With the essence of this literature, examples of the traditional close to the contemporary. A last, association is made with the absurd literature. The contemporary man as being object and its configuration represented in the field of the dreams and its possibilities. At the end of the work, a "post scriptum" suggests a more imersive reading of tales in the entire that appeared broken into fragments along the research

A paz tensa da chama fugaz: a configuração do amor no romance contemporâneo, Lygia Fagundes Telles e Lídia Jorge

This thesis A paz tensa da chama fugaz: a configuração do amor no romance contemporâneo, Lygia Fagundes Telles e Lídia Jorge aims to study the configuration of Love in contemporary novels. Their corpuses of study are the novels As horas nuas (1989), by the Brazilian writer Lygia Fagundes Telles; and O vento assobiando nas gruas (2002), by the Portuguese writer Lídia Jorge. The following research tries to understand how the characters from those texts deal with some love questions on the context of the contemporary narrative; it also tries to comprehend the love expression which is formed as a contradictorily fluid feeling and intensely wanted, which are important points concerning the love discourse at the present day. As a critic-comparative study, this research focuses on the problematic concerned love as a synonym of Eros, in other words, the relation between lovers, analyzed through social and philosophical perspective. Through that, this work broadens the study of two contemporary novels, and it also establish connections between the characters from those novels and the literary environment where they are placed, once it focuses on the human and social context presented in this books. The thesis ends calling attention to the dichotomy of love and death, to the image of love which grows through absence and through the longing of completeness of the human being; that is why this work sustains that the Lygia Fagundes Telles and Lídia Jorge update and materialized in their texts the plurality of contemporary love conception, which continues to be contradictory, fragmented and problematic

Controle de qualidade e dosimetria em equipamentos de tomografia computadorizada

OBJETIVO: Avaliação de condições dos equipamentos e dosimetria em setores de tomografia computadorizada utilizando protocolos de cabeça, abdome e coluna lombar em pacientes adultos (em três equipamentos distintos) e pediátricos com até um ano e meio de vida (em um dos equipamentos avaliados). MATERIAIS E MÉTODOS: Foram estimados o índice de dose em tomografia computadorizada e a dose média em cortes múltiplos, em exames com pacientes adultos, em três distintos equipamentos. Ainda foram estimadas as doses na superfície de entrada e as doses absorvidas em exame de cabeça para pacientes adultos e pediátricos em um dos equipamentos avaliados. RESULTADOS: Foram realizados testes de controle de qualidade, mecânicos, demonstrando que os equipamentos satisfazem as especificações de uso estabelecidas pelas normas vigentes. Os resultados da dosimetria mostraram que valores de dose média em cortes múltiplos excederam em até 109,0% os valores de níveis de referência, apresentando consideráveis variações entre os equipamentos avaliados neste estudo. As doses absorvidas obtidas com protocolos pediátricos são inferiores aos de pacientes adultos, apresentando redução de até 51,0% na tireoide. CONCLUSÃO: Neste estudo foram avaliadas as condições de operação de três equipamentos tomográficos, estabelecendo quais parâmetros devem ser trabalhados para a implantação de um programa de controle de qualidade nas instituições onde esta pesquisa foi desenvolvida.

Treatment of gingival recession: Comparative study between subepithelial connective tissue graft and guided tissue regeneration

Background: Various procedures have been proposed to treat gingival recession, but few studies compare these procedures to each other. The purpose of this study was to evaluate a clinical comparison of subepithelial connective tissue graft (SCTG) and guided tissue regeneration (GTR) with a collagen membrane in the treatment of gingival recessions in humans. Methods: Twenty-four defects were treated in 12 patients who presented canine or pre-molar Miller Class I and/or II bilateral gingival recessions. Both treatments were performed in all patients, and clinical measurements were obtained at baseline and 18 months after surgery. These clinical measurements included gingival recession height (GR), root coverage (RC), probing depth (PD), keratinized tissue width (KT), and final esthetic result. Results: Both SCTG and GTR with a bioabsorbable membrane and bone graft demonstrated significant clinical and esthetic improvement for gingival recession coverage. The SCTG group was statistically significantly better than GTR for height of GR (SCTG = 0.2 mm, GTR = 1.12 mm, P = 0.02) and KT (SCTG = 4.58 mm, GTR = 2.5 mm, P <0.0001). However, PD was statistically significantly better for GTR than SCTG treatment (GTR = 1.66 mm, SCTG = 1.00, P = 0.01). The 2 procedures were statistically similar in root coverage (SCTG = 95.6%, GTR = 84.2%, P = 0.073). The esthetic condition after both treatments was satisfactory (P = 0.024). Conclusions: It was concluded that the gingival recessions treated with the SCTG group were superior for GR, RC, and KT clinical parameters, while GTR demonstrated better PD reduction. The final esthetic results were similar using both techniques.

Nerolidol, an antiulcer constituent from the essential oil of Baccharis dracunculifolia DC (Asteraceae)

In this study, the antiulcerogenic effect of essential oil from Baccharis dracunculifolia was evaluated using the model of acute gastric lesions induced by ethanol. The ulcerative lesion index (ULI) was significantly reduced by oral administration of the essential oil of B. dracunculifolia at doses of 50, 250 and 500 mg/kg which reduced the lesions by 42.79, 45.70 and 61.61%, respectively. The analysis of the chemical composition of the essential oil from B. dracunculifolia by GC showed that this was composed mainly of mono- and sesquiterpenes and the majority compound was nerolidol. Therefore, antiulcerogenic activity of nerolidol (50, 250 and 500 mg/kg) was investigated using ethanol-, indomethacin- and stress-induced ulcer models in rat. In the stress-induced ulcer model, a significant reduction of the ULI in animals treated with nerolidol (50, 250 and 500 mg/kg) and cimetidine (100 mg/kg) was observed, compared to the control group (p < 0.05). The percentage of inhibition of ulcer was 41.22, 51.31, 56.57 and 53.50% in groups treated with 50, 250, 500 mg/kg of nerolidol and 100 mg/kg of cimetidine (positive control), respectively. Regarding ethanol- and indomethacin-induced ulcer models, it was observed that the treatment with nerolidol (250 and 500 mg/kg) significantly reduced the ULI in comparison with the control group (p < 0.05). The dose of 50 mg/kg reduced the parameters analyzed but this was not statistically significant. In the ethanol-induced model percentage of inhibition of ulcer was 34.20, 52.63, 87.63 and 50.87% in groups treated with 50, 250, 500 mg/kg of nerolidol and 30 mg/kg of omeprazol (positive control), respectively. In indomethacin-ulcer the percentage of inhibition of ulcer was 34.69, 40.80, 51.02 and 46.93% in groups treated with 50, 250, 500 mg/kg of nerolidol and 100 mg/kg of cimetidine (positive control), respectively. The results of this study show that nerolidol displays antiulcer activity, as it significantly inhibited the formation of ulcers induced in different animal models. However, further pharmacological and toxicological investigations, to delineate the mechanism(s) of action and the toxic effects, are required to allow the use of nerolidol for the treatment of gastric ulcer. © 2007 Verlag der Zeitschrift für Naturforschung.
