Marcadores de prognóstico na leucemia linfocítica cr?nica

Abstract: chronic lymphocytic leukemia is characterized by a variable clinical course that cannot be predicted accurately by clinical staging systems in individual patients. this prompted the investigation of other prognostic factors capable of adding predictive power to clinical staging systems or even substituting them. among the clinical and biological markers found initially, genomic aberrations and the mutational status of immunoglobulin genes demonstrated a high level of prognostic prediction in cll. however, the techniques employed in these studies are laborious and inaccessible for most hematology-oncology facilities, which motivated the hunt for surrogate markers. among the potential surrogates, cd38 and zap-70 play an independent prognostic role in cll, with a predictive power as precise as (or even better than) the immunoglobulin mutational profile, pointing for its replacement in the near future. novel factors such as lpl, lpl/adam29 and vimentin have showed quite attractive preliminary results, but still wait for validation in further series of patients. besides the recognition of powerful biological markers, the clinical staging systems should not be abandoned so far.
Famílias complexas: tendências de evolu??o
Sociologia, Problemas e Práticas , 2003,
Abstract: an endeavour is made to trace the main development trends in complex family households in portugal from 1991 to 2001, on the basis of an analysis of census data. to characterise this specific way of organising family life, the internal family structure of this complexity and the social profile of the people involved will be analyzed. inter-regional variation in family complexity, a classical subject of sociological and anthropological observation, will also be analysed. throughout the analysis an attempt will be made to present some of the clues as to why the relative importance of complexity in the overall panorama of domestic structures in portugal has progressively decreased.

Abstract: Questiona-se a possibilidade de uma teoria semantica formal explicar os fen menos de expans o de sentido inerentes à diferencia o do significado lexical em acep es e a validade de uma “divis o de trabalho” entre teoria semantica e teoria pragmática que possa, alternativamente, dar conta deles. Trata-se das quest es da delimitabilidade do significado lexical, da sua independência ou n o em face da cogni o e de fatos de cristaliza o históricocultural de significa es, bem como da sua tradutibilidade através de parametros elementares e finitos. L’article questionne si une théorie sémantique formelle, ou une “division de travail” entre théorie sémantique et théorie pragmatique, peut expliquer les phénomèmes d’expansion de sens inhérents à la differentiation du signifié SIGNóTICA, 14: 163-181, jan./dez. 2002 179 lexical en aceptions. Il aborde encore les questions: de la délimitation des signifiés lexicaux; de son indépendance vers la cognition et des faits de consolidation historique de significations; de la possibilité de les traduire par moyen de paramètres élémentaires et finis.
Using the Project Approach in a Teacher Education Practicum
Teresa Vasconcelos
Early Childhood Research & Practice , 2007,
Abstract: This paper describes the early childhood teacher training program and the role of the Project Approach in the final practicum for student teachers in the Lisbon School of Education, Portugal. Student teachers, cooperating teachers, university supervisors, and instructors of teaching methods worked together to involve young children in interesting projects. This cooperation provided an opportunity for innovation and experimentation and, especially, a context for teacher educators to deepen their understanding of their roles and to improve their teaching strategies. As a consequence, the final practicum became central to the teacher education program. The article concludes with seven lessons learned as a result of this process.

Argila: uma vis o romantica do Brasil?
Cid Vasconcelos
Ciberlegenda , 2011,
Abstract: O artigo pretende efetivar uma leitura do filme Argila (1940), de Humberto Mauro, sob o prisma de suas influências romanticas, enfatizando as rela es afetivas do triangulo amoroso, aconstru o dos personagens e de símbolos identitários nacionais como elementos importantes na constru o da mesma. O ideário romantico demonstra ser um importante aliado na defesa de uma caracteriza o do popular que procura se distanciar do preconceito a ele dirigido pelos intelectuais da Primeira República, aproximando-se do ideário estado-novista. Os comentários se apóiam no próprio texto fílmico como igualmente em material bibliográfico sobre o filme e o cineasta, além detextos sobre e contemporaneos ao período histórico em quest o. Com rela o à estética romantica s o utilizados tanto os textos de José de Alencar, como comentaristas dos mesmos e do romantismo de modo mais amplo.
Avalia??o da perda sanguínea na artroplastia total do joelho com e sem soltura do torniquete

Abstract: objective: to evaluate blood loss in patients submitted to cemented total knee arthroplasty with and without perioperative tourniquet release for hemostasis. methods: seventy-two patients (eighty knees) were submitted to total knee arthroplasty, allocated into two groups: in group 1, in which the pneumatic tourniquet was maintained until suture and dressing of the operated wound, and group 2, in which the pneumatic tourniquet was released intraoperatively after cementing the prosthesis, with direct hemostasis, before the suture and dressing. the patients were evaluated for blood loss by the suction drain, and hemoglobin and hematocrit counts, at intervals of 2, 24 and 48 hours in the postoperative period tube. results: there was no significant difference between the groups in terms of postoperative blood loss or decrease in hemoglobin and hematocrit parameters. only one patient, from group 2, required a blood transfusion in the postoperative period. conclusion: postoperative blood loss in tka was similar with and without perioperative release of the pneumatic tourniquet for hemostasis.
Development of a methodology for microstructural description
Vasconcelos, Vanderley de;Vasconcelos, Wander L.;
Materials Research , 1999, DOI: 10.1590/S1516-14391999000300003
Abstract: a systematic methodology for microstructural description can help the task of obtaining the processing x microstructure x properties x performance relationships. there are, however, some difficulties in performing this task, which are related mainly to the following three factors: the complexity of the interactions between microstructural features; difficulties in evaluating geometric parameters of microstructural features; and difficulties in relating these geometric parameters to process variables. to solve some of these problems, it is proposed a methodology that embodies the following features: takes into account the different possible types of approaches for the microstructural description problem; includes concepts and tools of total quality management; is supported on techniques of system analysis; and makes use of computer modeling and simulation and statistical design of experiments tools. the methodology was applied on evaluating some topological parameters during sintering process and its results were compared with available experimental data.
