Sobre os limites da interpreta o. O debate entre Umberto Eco e Jacques Derrida
Eduardo Ramalho Rabenhorst
Prim@ Facie , 2002,
Abstract: A proposta do presente trabalho é examinar o debate sobre os limites da atividade interpretativa, tomando por base as propostas do desconstrucionismo de Jacques Derrida e da semiologia de Umberto Eco. Tentaremos mostrar que as discordancias entre as duas perspectivas poderiam ser suficientemente aplainadas a partir da identifica o de um ponto de convergência fornecido pelas idéias de contexto e de compreens o intersubjetiva.

Prim@ Facie , 2003,
Abstract: O principal escopo do presente artigo é mostrar,tomando por base a proposta formulada pelo filósofo francêsPaul Ricoeur, que a interpreta o jurídica n o pode serreduzida apenas aos momentos de compreens o de um textolegal e de sua aplica o aos concretos, mas que ela exige umterceiro momento, a saber, o da interpreta o dos fatos.
Filosofia ou teoria do direito?
Eduardo Rabenhorst
Problemata : International Journal of Philosophy , 2011, DOI: 10.7443/problemata.v1i2.10123
Abstract: O presente trabalho aborda o problema da distin o entre a filosofia jurídica e a chamada teoria geral do direito, propondo uma crítica ao modelo "descritivista" da cientificidade do direito que decorre da segunda. The present work deals with the problem of distinguishing between Legal Philosophy and the so-called General Theory of Law , and proposes a critique to the "descriptive" model of the scientific character of Law which follows that General Theory.
Genetic Parameters Estimates Associated to Conversion of Nicotine to Nornicotine in Burley Tobacco  [PDF]

Abstract: Nicotine represents the predominant alkaloid in cultivated tobacco. In burley varieties, during senescence and curing of leaves, nicotine can be converted to nornicotine, which is highly undesirable because of its relationship with the tobacco specific nitrosamines formation. Thus, an alternative for producing varieties with low or null nornicotine content would be to select plants or progenies for traits related to nicotine conversion. Therefore, understanding genetic control and inheritance underlying this process is important to chooseappropriate strategies in breeding programs. Two contrasting inbred lines for nicotine conversion to nornicotine, TN 90 and BY 37, have been crossed to obtain the segregating generations (F2 and BCs). Genetic parameters of mean and variance, as well as the average degree of dominance and heritability were estimated. It has been found that nicotine conversion has predominantly additive effects, and in addition, narrow sense heritabilities at the individual level were higher than 65%. Both are desirable conditions for conducting a selection program of burley tobacco aiming at development of inbred lines associating yield and other traits with low or null nicotine conversion.

Abstract: in order to evaluate the monophyly of the phyllachorales from a molecular standpoint and elucidate its phylogenetic relationships with other orders, a segment of the 18s rrna gene from several representatives of the phyllachorales, including species of glomerella, phyllachora, coccodiella (=coccostroma), sphaerodothis, ophiodothella, as well as magnaporthe was sequenced. maximum parsimony analysis revealed that the phyllachorales was a polyphyletic assemblage of taxa. none of the other members of the phyllachorales, which produced either a clypeus or stroma, clustered with glomerella. of the taxa examined, was coccodiella the closest relative of phyllachora. magnaporthe was closely related to the diaporthales. our 18s rdna data highly supported glomerella being accommodated in a separate family.

Hepatectomia total com preserva??o da veia cava inferior: "piggy-back" experimental em c?es
Castro-e-Silva Jr, Orlando de;Ramalho, Fernando S;Pacheco, Eduardo G;

Abstract: during the recipient hepatectomy in liver transplantation, preservation of the retrohepatic segment of the inferior vena cava has several advantages: it decreases warm ischemia time by eliminating the infrahepatic caval anastomosis, eliminates the need for venovenous bypass and eases retransplantation. removal of the liver of the dog without sacrificing the inferior vena cava has been considered impossible because of the intrahepatic course of the vena cava at the sites of entry of the hepatic veins. the following report reviews the history of the piggyback method, and discuss about the feasibility of the total removal of the liver without injury to the vena cava in the dog.
In vitro evaluation of apical microleakage using different root-end filling materials
Valera, Márcia Carneiro;Camargo, Carlos Henrique Ribeiro;Carvalho, Alessandra Sverberi;Gama, Eduardo Ramalho Pereira;
Journal of Applied Oral Science , 2006, DOI: 10.1590/S1678-77572006000100010
Abstract: the objective of this study was to evaluate the apical leakage of retrograde cavities filled with portland cement (concrebrás s/a-mg-brazil), proroot mtatm (dentsply international, johnson city, tn, usa) and sealapex (kerr corporation, orange, california, usa) with addition of zinc oxide (odahcam herpo produtos dentários ltda, rio de janeiro, rj, brazil). forty-two extracted single-rooted human teeth were decoronated and used for this study. the root canals were instrumented at 1.0mm short of the apical foramen using the step-back technique to an apical iso size 60. the roots were obturated with gutta-percha points and sealer sealapex (kerr corporation-usa) and then 3mm of each root apex was sectioned at a 90° angle. ultrasonic retrograde preparation was performed with a diamond tip to 3mm depth and the roots were randomly divided into 3 groups according to the filling material: g1-portland, g2-proroot mta, g3- sealapex zinc oxide-added cement. the root surfaces were covered with nail varnish up to 2mm from the apical foramen, immersed in simulated tissue fluid for 30 days, and then immersed in 0.2% rhodamine b solution for 24 hours for evaluation of marginal leakage. the results showed mean leakage of 0.75, 0.35 and 0.35 for groups 1, 2 and 3, respectively; however, kruskal-wallis test revealed that there was no statistically significant difference among the results (p>0.05).

Abstract: objective: 3-hydroxy-3-methylglutaryl coenzyme a (hmg-coa) reductase inhibitors, or statins, have been associated with improved clinical outcomes after ischemic stroke and subarachnoid hemorrhage, but with an increased risk of incidental spontaneous intracerebral hemorrhage (ich). we investigated whether the statin use before ich, was associated with functional independence, 90 days after treatment. method: we analyzed 124 consecutive ich patients with 90-day outcome data who were enrolled in a prospective cohort study between 2006 and 2009. eighty-three patients were included in this study. among ich survivors, univariate cox regression models and kaplan-meier plots were used to determine subject characteristics that were associated with an increased risk of recurrence. statin usage was determined through interviewing the patient at the time of ich and confirmed by reviewing their medical records. independent status was defined as glasgow outcome scale grades 4 or 5. results: statins were used by 20 out of 83 patients (24%) before ich onset. there was no effect from pre-ich statin use on functional independence rates (28% versus 29%, p=0.84) or mortality (46% versus 45%, p=0.93). conclusion: pre-ich statin use is not associated with changes to ich functional outcome or mortality.

Arquivos de Neuro-Psiquiatria , 2012, DOI: 10.1590/S0004-282X2012000300009
Abstract: objectives: our aim was to evaluate the relationship between serum c-reactive protein (crp) levels and the neurological prognosis and development of vasospasm in patients with aneurysmal subarachnoid hemorrhage (asah). methods: eighty-two adult patients with asah diagnoses were prospectively evaluated. glasgow coma scale (gcs) score, hunt and hess grade, fisher grade, cranial ct scans, digital subtraction angiography studies and daily neurological examinations were recorded. serial serum crp measurements were obtained daily between admission and the tenth day. glasgow outcome scale (gos) and the modified rankin scale (mrs) were used to assess the prognosis. results: serum crp levels were related to severity of asah. patients with lower gcs scores and higher hunt and hess and fisher grades presented statistically significant higher serum crp levels. patients with higher serum crp levels had a less favorable prognosis. conclusions: increased serum crp levels were strongly associated with worse clinical prognosis in this study.
