OBJETIVO: Avaliar o epitélio ciliar interno (ECI) do corpo ciliar após aplicação de mitomicina C (MMC) sob retalho escleral, em animais tratados com dois tipos de inibidores da produção do humor aquoso. MÉTODOS: Foram estudados ambos os olhos de 16 coelhos divididos em 4 grupos experimentais. Foi realizado retalho escleral em todos os olhos dos animais, mas apenas os olhos direitos (OD) receberam MMC. No grupo 1 (G1) não houve tratamento prévio. Nos grupos G2 e G4 foi administrada acetazolamida e nos grupos G3 e G4 maleato de timolol. O ECI foi examinado à microscopia eletrônica de transmissão (MET). Os olhos esquerdos formaram os grupos controle. RESULTADOS: em todos os grupos exceto no G1 OE, foram observadas: retração das células e/ou alargamento entre invaginações, mitocôndrias com rarefação, vesículas claras e corpos densos. A membrana limitante interna estava espessada, descontínua ou descolada em todos grupos exceto G1 OE e G2 OE. Foi observada liberação de material citoplasmático apenas nos grupos tratados com inibidores da produção de humor aquoso. CONCLUSÕES: 1- MMC, acetazolamida e maleato de timolol causaram alterações morfológicas no epitélio ciliar mesmo usados isoladamente. 2- A associação MMC e acetazolamida causou mais alterações do que a acetazolamida isoladamente, mas não mais do que a MMC isoladamente. 3- Nas demais associações as alterações foram semelhantes.

The aim of this study was to examine the endothelial surface and to perform a morphometric analysis of the corneal endothelial cells in normal eyes of dogs using specular microscopy. Morphometric analysis with regard mean cell area and cell density was performed. Both eyes of ten mixed-breed, males and females, with 6 years of age, weighing about 15 kg euthanatized for reasons unrelated to this study were evaluated. Eyes were examined to determine that they did not have visible ocular disease and transported to the laboratory in moist chamber. Using a contact specular microscope the corneal endothelium was examined. Three images of the central corneal endothelium of each eye were obtained. The mean cell area and the cell density of the corneal endothelial cells were obtained using software for corneal endothelium analysis and density measurement. The mean cell area was 395 ± 36 μm 2 and the endothelial cell density was 2555 ± 240 cells/mm2. The present work demonstrates that the normal corneal endothelium of dog is similar to those described in human.

Em Pelos olhos do menino de engenho, a socióloga Carla de Fátima Cordeiro busca identificar um pensamento social relativo à questão racial no Brasil na década de 1930, a partir da análise dos personagens negros presentes na obra de José Lins do Rego. Descendente de senhor de engenho, o escritor paraibano, ao lado de Gilberto Freyre, foi um dos mais destacados participantes do Movimento Regionalista Nordestino, que defendia os verdadeiros valores brasileiros, baseados na ordem social anterior: latifundiária, escravista e açucareira. Lins do Rego criou seus principais romances, considerados fortemente autobiográficos, entre 1934 e 1942, época em que as velhas estruturas econômicas e de relações sociais dos engenhos de cana-de-açúcar se encontravam em franco declínio. A autora traz à luz um processo fundamental da História do país, concluindo que o processo de decadência dos velhos modos de produção refletiu-se na narrativa dos romances, em que a violência, principalmente contra os subalternos negros, tornou-se cada vez mais presente. Dessa forma, ela demonstra como a ficção literária expressou o comportamento do poder patriarcal, que passou a sentir-se ameaçado pela inevitável introdução do trabalho livre.

This investigation has as an objective to observe the translation of the word “eyes” and its collocates, in similar and (re)used fragments extracted from two books written by Clarice Lispector, A Descoberta do Mundo, translated by Giovanni Pontiero as Discovering the World and Uma Aprendizagem ou o Livro dos Prazeres, translated by Richard A. Mazzara and Lorri A. Parris as An Apprenticeship or The Book of Delights.Another objective is to identify aspects of normalization found in the respective translations of these fragments. The metodology is situated in the field of Corpus-based Translation Studies, (proposed by Baker, 1993, 1995, 1996, 1999, 2004; studies on normalization by de Scott, 1998); research and project by Camargo 2003a, 2003b, 2004, 2008), and in Corpus Linguistics (studies by Berber Sardinha, 2004); also, it is based on the author’s critical heritage (studies by Gotlib, 1993, 2009; Nunes, B., 1995; Sant‘Anna, 1997; Ruggero 2000; Sá, O., 2000; Franco Júnior, 2000; Ranzolin (1985), Varin, 2002; e Cherem, 2003). The results found in this research enabled to carry out a comparative study among the respective translators concerning tendencies to normalization and show Pontiero’s smaller tendency in relation to the couple of translators Richard A. Mazzara e Lorri A. Parris.

Os olhos são a janela da alma. De outra forma: o olhar revela o não dito, a intimidade, o recalcado. O filme O segredo dos seus olhos, do diretor argentino Juan José Campanella, com roteiro de Eduardo Sacheri, também autor do romance A pergunta dos seus olhos e do conto El Hombre, que inspiraram o filme, nos coloca na frente desta questão. A memória individual e coletiva se constrói a partir de pequenos indícios. Esta reflexão se propõe estudar os procedimentos pelos quais esses indícios habilitam a reconstrução da trama e a costura com a história do país que os autores propõem por caminhos originais.

As a hybrid genre, the narrative of Carlo Levi is an objective account and subjective elaboration that are equalized in a literary form. Written between 1943 and 1944, the book evokes with an atmosphere of memoir the period of 1935 and 1936, the writer’s exile. The film based on the narration fragmentizes the daily life of the problematic region and highlights the truth aimed by the discourses composed in times of crises, reinforced by action and expression without provincialism and also without a compensating aristocratic pose. It is possible to see some incapacity of the film by Rosi, natural to a certain degree, to translate the synthesis of literary treatment and socio-historical reflection. For this reason it is necessary to read the adaptation as an attitude about the literary matter and the result of historical experience. The memoir character relies on the artifice that makes good use of the book’s opening, the author’s short monologue, its narrative frame. The presence of paintings materializes the questions about the absurd contained in them

The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

In massal rearing of natural enemies with the goal of biological control, the procedures adopted for establishment and maintenance of the individual founders of the colonies may have undesirable effects on population genetic structure of laboratory. This situation influences the success of rearing and effectiveness in the field. The objective of this study was to evaluate, along of generations two laboratory populations (Jaboticabal and Piracicaba) of Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae), founded with different numbers of adults (1, 5, 10, 15 and 20 couples), the frequency of morphological variants, size of wings and eye color, such as parameters for inferences about the homozygosity degrees. For eye color were assessed the frequency, while for the size of wings was measured the width and the length of the right mesothoracic wings. The eye color variants for C. externa populations may be monitored in the laboratory aiming at detecting inbreeding, whereas the measurements of length and width of wings should not be adopted for this purpose.
