Macedonio Fernández: la construcción de imposibles

El presente trabajo es un análisis teórico de la obra del escritor argentino Macedonio Fernández (1874-1952). El objetivo de esta investigación es analizar la narrativa que presenta en algunos de sus cuentos –“Papeles de Recienvenido” (1929), “Tantalia” (1930), “Cirugía psíquica de extirpación” (1941), “A Fotografiarse” (1944), “Donde Solano Reyes era un vencido y sufría dos derrotas cada día” (1944)– y la teoría literaria que desarrolla en sus ensayos –sobre todo en “Para una teoría del Arte”. Para ello, se ha escogido a lo “imposible” como una categoría pertinente para problematizar la narrativa de Fernández, esto desde la tensión existente entre las categorías de ficción y realidad. En la narrativa macedoniana, la realidad se transforma por la operación de lo ficcional, lo que genera ciertos “imposibles” para una lógica de la realidad, siendo, al mismo tiempo, posibles para una lógica de lo ficcional. Por esta vía, se analizarán los conceptos teóricos propuestos por el autor – Belarte y Autorística– para ahondar y explicitar el lugar que estos tienen dentro de la narrativa que presenta en sus cuentos y para relacionarlos con las categorías que se han detallado. Además, cabe indicar que uno de los alcances de la presente investigación es el diálogo que se establece con la teoría lingüística de Roman Jakobson (1896-1982) y de Émile Benveniste (1902-1976), de quienes se recogen algunas de las propuestas que plantean en sus textos. Macedonio Fernández, aunque ha influenciado el estilo de escritores como Jorge Luis Borges y Julio Cortázar, es un autor poco estudiado en el ámbito académico latinoamericano. En el caso de estudios dentro de nuestro país, según la bibliografía revisada, no se ha hecho una investigación formal sobre la obra de este importante escritor de la vanguardia literaria argentina. Esta es una de las razones por las cuales se ha considerado necesaria la presente propuesta de trabajo.

Estudo dos mixozoários (Myxozoa : Myxosporea) parasitos dos peixes characiformes Acestrorhynchus lacustris (Lütken, 1875) e Steindachnerina insculpta (Fernández-Yépez, 1948) coletados no Rio do Peixe, médio Rio Tietê, SP, Brasil

The São Paulo State has as one of its main rivers the Tietê, which is an extremely important source because of its biodiversity, use in navigation and mainly as direct supplier of water for thousands of people in the region. Currently, the biodiversity of marine and freshwater ecosystems has been threatened, primarily by environmental problems resulting from the degradation of ecosystems, an example is the stretch of the Middle Tietê River, where the Barra Bonita dam (SP) focused virtually the whole load organic effluents from the metropolitan region of São Paulo, leading to eutrophication with the loss of water quality. This basin is located in the Peixe’s River, a tributary of the Barra Bonita whose sources are on the slopes of the Cuesta de Botucatu, presenting an altitudinal gradient in a good state of conservation and water quality. From another perspective, the studies related to parasites and other pathogens of aquatic organisms have considerably increased the relevance, especially those hosts with potential for growing and marketing, given the significant increase these activities in Brazil and worldwide. Among the agents responsible for diseases in fish are the myxosporean, which can cause major economic damage, with high mortality ratios. Based on the above, this study evaluated the biodiversity of myxosporean parasites of two species of fish Acestrorhynchus lacustris and Steindachnerina insculpta. During the period January to November 2012, 40 specimens of Acestrorhynchus lacustris and 33 specimens of Steindachnerina insculpta were collected from the Peoxe’s river at four different points. The necropsies were performed and all organs were analyzed looking for myxosporean. Only the species Steindachnerina insculpta had their gills parasitized by two species of the genus Henneguya

A maldição das palavras e o sujeito dilacerado de Marcelo Mirisola (2009)

There is an area in the Brazilian Contemporary Literature which is articulated according to the first person narrator who presents the problematic of the own creational action, the expression of a conflictual subjectivity divided between the vertiginous dive into itself – what would imply in a renounce of the world and the reality, where the authors’ work are their only matter – and the social participation - not as an awareness, but as the recognition of the limits and impasses which the real representation imposes on the creative writing. Therefore, this article proposes a reading on the novel O Azul do Filho Morto (2002) by Marcelo Mirisola, to try to situate him into the recent Brazilian literary production, as well as to reflect on his narrative the complex notion of authorship which is called into question on his novels, since they produce an intrincate imbrication between the fictional subject and the empirical image of the writer himself, breaking and confusing the limits between the fictional discourse and the extralinguistic reality which is evoked, manipulated, distorted and made unstable on his representational process.

Can repair increase the longevity of composite resins? Results of a 10-year clinical trial

The aim of this double-blind clinical trial was to assess the longevity of repairs to localized clinical defects in composite resin restorations that were initially planned to be treated with a restoration replacement. Methods Twenty-eight patients aged 18–80 years old with 50 composite resin restorations (CR) were recruited. The restorations with localized, marginal, anatomical deficiencies and/or secondary caries adjacent to CR that were “clinically judged” to be suitable for repair or replacement according to the USPHS criteria were randomly assigned to Repair (n = 25) or Replacement (n = 25) groups, and the quality of the restorations was scored according to the modified USPHS criteria. The restorations were blind and two examiners scored them at baseline (Cohen Kappa agreement score 0.74) and at ten years (Cohen Kappa agreement score 0.87) restorations. Wilcoxon tests were performed for comparisons within the same group (95% CI), and Friedman tests were utilized for multiple comparisons between the different years within each group. Results Over the decade, the two groups behaved similarly on the parameters of marginal adaptation (MA) (p > 0.05), secondary caries (SC) (p > 0.05), anatomy (A) (p < 0.05), and colour (C) (p > 0.05). Conclusions Given that the MA, SC, A and C parameters behaved similarly in both groups, the repair of composite resins should be elected when clinically indicated, because it is a minimally invasive treatment that can consistently increase the longevity of restorations. Clinical significance The repair of defective composite resins as an alternative treatment to increase their longevity proved to be a safe and effective treatment in the long term.

Longitudinal results of a 10-year clinical trial of repair of amalgam restorations

The aim of this prospective, blind, and randomized clinical trial was to assess the effectiveness of repair of localized clinical defects in amalgam restorations that were initially scheduled for replacement. A cohort of 20 patients with 40 (Class I and Class II) amalgam restorations that presented one or more clinical features that deviated from the ideal (Bravo or Charlie) according to US Public Health Service criteria, were randomly assigned to either the repair or the replacement group—A: repair, n = 19; and B: replacement, n = 21. Two examiners who had calibration expertise evaluated the restorations at baseline and 10 years after according to seven parameters: marginal occlusal adaptation, anatomic form, surface roughness, marginal staining, contact, secondary caries, and luster. After 10 years, 30 restorations (75%) were evaluated (Group A: n = 17; Group B: n = 13). Repaired and replaced amalgam restorations showed similar survival outcomes regarding marginal defects and secondary caries in patients with low and medium caries risk, and most of the restorations were considered clinically acceptable after 10 years. Repair treatment increased the potential for tooth longevity, using a minimally interventional procedure. All restorations trend to downgrade over time.
