Destecendo uma carta pela estelística da expressão

We aim to analyse the text written by Eça de Queirós, “Carta ao Sr. Mollinet”, theorizing the stylistics of Marcel Cressot’s expression, called “the texture”. We discuss what is sought in the reading of a text nowadays: the form, the meaning or the form that produces meaning? Even though through stylistics there is identifi cation and description of the linguistic categories in the text, the morphological identifi cation in the enunciation level is emptied, if it is done separately. It is from the semantic-syntactic and melodic axes that Eça infl ates his characters with life. The characterization of Pacheco and Portuguese people is supported by the nexus, a producer of antagonistic meta-signifi cation in relation to the fi rst meaning. Eça’s irony results from the reverse meaning – from “ne pas dire”. The nexus is the great meaningful cohesion between logical and metalogic discourse – producing new signifi cations; multiplying verbal resources, which are created in order to metamorphose the linguistic sign into pictorial or iconic signs. The irony governs the whole constructive tessitura that stems from new referents, which result from demiurgical relations between themselves because of the metalogical process, as it allows to establish and change the direction when sign and referent, signifi er and signifi ed, utterance and context are related. The analysis of Eça’s selected text enriches the discoveries presented by the Stylistics of Expression.

In vitro differentiation of mesenchimal stem cells of dogs into osteogenic precursors

Lima S.A.F., Wodewotzky T.I., Lima-Neto J.F., Beltrao-Braga P.C.B. & Alvarenga F.C.L. 2012. [In vitro differentiation of mesenchimal stem cells of dogs into osteogenic precursors.] Diferenciacao in vitro de celulas-tronco mesenquimais da medula ossea de caes em precursores osteogenicos. Pesquisa Veterinaria Brasileira 32(5):463-469. Departamento de Reproducao Animal e Radiologia Veterinaria, Faculdade de Medicina Veterinaria e Zootecnia, Universidade Estadual Paulista, Campus de Botucatu, Distrito de Rubiao Junior s/n, Botucatu, SP 18618-970, Brazil. E-mail: silviavet@usp.br The aim of our research was to evaluate the potential for osteogenic differentiation of mesenchimal stem cells (MSC) obtained from dog bone marrow. The MSC were separated using the Ficoll method and cultured under two different conditions: DMEM low glucose or DMEM/F12, both containing L-glutamine, 20% of FBS and antibiotics. MSC markers were tested, confirming CD44+ and CD34- cells with flow cytometry. For osteogenic differentiation, cells were submitted to four different conditions: Group 1, same conditions used for primary cell culture with DMEM supplemented media; Group 2, same conditions of Group 1 plus differentiation inductors Dexametazone, ascorbic acid and beta-glicerolphosphate. Group 3, Cells cultured with supplemented DMEM/F12 media, and Group 4, same conditions as in Group 3 plus differentiation inductors Dexametazone, ascorbic acid and beta-glicerolphosphate. The cellular differentiation was confirmed using alizarin red and imunostaining with SP7/Osterix antibody. We observed by alizarin staining that calcium deposit was more evident in cells cultivated in DMEM/F12. Furthermore, by SP/7Osterix antibody immunostaining we obtained 1:6 positive cells when using DMEM/F12 compared with 1:12 for low-glucose DMEM. Based on our results, we conclude that the medium DMEM/F12 is more efficient for induction of differentiation of mesenchymal stem cells in canine osteogenic progenitors. This effect is probably due to the greater amount of glucose in the medium and the presence of various amino acids.

Silicon location through backscattered electron imaging and X-ray microanalysis in leaves of Cyperus ligularis L. and Rhynchospora aberrans C. B. Clarke (Cyperaceae)

(Silicon location through backscattered electron imaging and X-ray microanalysis in leaves of Cyperus ligularis L. and Rhynchospora aberrans C. B. Clarke (Cyperaceae)). The Cyperaceae show the ability to incorporate silicon by depositing colloidal silica, which is recorded by the occurrence of projections in the form of cones, in inner tangential walls of some epidermal cells or "silica cells". Leaves of C. ligularis and R. aberrans were analyzed through the technique of electron backscatter. Cyperus ligularis accumulates silica, in addition to "silica cells", in some stomata, trichomes and the cell walls that surround the cavities of the aerenchyma. The silica in the latter occurs in various forms; however, the cells located near the vascular bundles have conical projections, similar to those of the epidermis. Rhynchospora aberrans presents "silica cells" whose projections have tapered "satellites". In this species, silica also occurs in stomata and certain epidermal cells adjacent to them. It appears that the silicon deposition occurs in combination with the wall (with no apparent structural changes), and structures of secretion, or projections of the wall. These structural changes in the species, and location, are probably related to functional and environmental factors, especially the soil, in addition to relation with taxonomic groups.

Chief Audit Executives’ Evaluations of Whistle-Blowing Allegations

This study examines the effects of the source of whistle-blowing allegations and potential for allegations to trigger concerns about reputation threats on Chief Audit Executives’ handling of whistle-blowing allegations. The participants for this study, 79 Chief Audit Executives (CAEs) and deputy CAEs, evaluated whistle-blowing reports related to financial reporting malfeasance that were received from either an anonymous or a non-anonymous source. The whistle-blowing reports alleged that the wrongdoing resulted from either the exploitation of substantial weaknesses in internal controls (suggesting higher responsibility of the CAE and internal audit) or the circumvention of internal controls (suggesting lower responsibility of the CAE or internal audit). Findings indicate that CAEs believe anonymous whistle-blowing reports to be significantly less credible than non-anonymous reports. Although CAEs assessed lower credibility ratings for the reports alleging wrongdoing by the exploitation of substantial weaknesses in internal controls, they allocated more resources to investigating these allegations.

La ciudad de Alejandría y los héroes que leen en las Vidas de Alejandro y César de Plutarco

Las Vidas de Alejandro y César de Plutarco contienen una comparación agonal entre ambos hegemónes a partir de los relatos heroicos que éstos consideran paradigmáticos y que justifican sus acciones: Alejandro lee las hazañas de Aquiles (Alex. 8; 26) y César lee las hazañas del propio Alejandro (Caes. 11). Esta cualidad lectora de los héroes toma un sesgo marcadamente libresco en dos pasajes de sus biografías, ligados a la ciudad de Alejandría. El primero es la fundación de la capital helenística por Alejandro (Alex. 26). El segundo es el sitio de César a esta ciudad, cuando ocurre el incendio que consume la Gran Biblioteca (Caes. 49). Este trabajo analiza cómo, en las Vidas, la ciudad egipcia concentra un legado del libro paideia, que conduce de Homero a Alejandro y de éste a César como un bastión de integración cultural, no exento de tensiones, en el sincrético y agonal mundo grecorromano
