ABSTRACT
Resumen Este trabajo se centró en el análisis respecto a la calidad y consistencia de una guía de entrevista, creada para estudiar las emociones en varones sin empleo, así como el método para la implementación de este instrumento. El objetivo fue develar cómo investigadores de dos grupos de investigación de dos universidades de México y Colombia aplicaron y probaron el uso de una entrevista semiestructurada con enfoque biográfico para develar emociones en un grupo de varones desempleados. El método involucró la aplicación y evaluación de la herramienta. La metodología se siguió en (N = 7 en Colombia + N = 14 en México) entrevistas con hombres sin empleo en dos ciudades latinoamericanas: Bogotá, Colombia y Guadalajara, México, por dos grupos de investigación, lo que permitió verificar la consistencia de la herramienta y la aplicabilidad durante el proceso investigativo. Los resultados indican la idoneidad y credibilidad de esta propuesta metodológica y guía de entrevista, probada y constatada en términos interdisciplinarios e interinstitucionales.
Abstract This work offers an analysis of the quality and consistency of an interview guide created to study the emotions in unemployed men, as well as the method for the implementation of this instrument. Our objective is to reveal how researchers from two research groups at two universities in Mexico and Colombia applied and tested a semistructured interview guide with a biographical approach to reveal the emotions in a group of unemployed men. Their methodology involved the application and evaluation of this tool and was followed in (N = 7 in Colombia + N = 14 in Mexico) interviews with unemployed men in two Latin American cities - Bogotá, Colombia and Guadalajara, Mexico - by two research groups. This application has allowed us to verify the consistency of the tool and its applicability during relevant research. Our results thus demonstrate the suitability and credibility of this methodological proposal and interview guide based on their testing and verification in interdisciplinary and interinstitutional contexts.
ABSTRACT
A utilização racional e correta de materiais odontológicos como protetores do complexo dentino-pulpar desencadeia mecanismos de defesa e reparo na dentina e no tecido pulpar. A importância do entendimento prévio da relação dentina-polpa, associada ao comportamento biológico, mecanismo de ação e propriedades físico-mecânicas dos materiais empregados em odontologia, permitiu ao profissional obter maior taxa de sucesso nos procedimentos clínicos de rotina. O acompanhamento da literatura científica, em associação com a experiência clínica, fornecerá parâmetros para a formação de opinião sobre os materiais e técnicas indicados nos procedimentos adesivos restauradores. A presente revisão de literatura descreve os efeitos da aplicação de materiais odontológicos no complexo dentino-pulpar...
Proper and correct use of dental materials on the dentin-pulp complex triggers different mechanisms of response and repair from dentin, and the pulp as well. It is important to understand the condition of dentin and pulp, along with the biological properties, biocompatibility and mechanisms of action of routinely used dental materials to achieve a successful restorative practice. Scientific sound literature associated to the clinical experience provide parameters for formation of opinion by the clinician on materials and techniques used for restorative procedures. This literature review describes the effects of the application of dental materials on the pulp-dentin complex...

Desde seu surgimento, os pinos fibrorresinosos têm sido muito utilizados na restauração de dentes tratados endodonticamente. Apesar do desenvolvimento nos últimos anos das técnicas adesivas, vários estudos têm demonstrado haver um importante percentual de falhas adesivas na interface pino-cimento resinoso. Dessa forma, a presente revisão de literatura expõe diferentes protocolos clínicos sugeridos na literatura científica e as novas possibilidades de tratamento de superfície, com o intuito de melhorar o desempenho clínico dos pinos fibrorresinosos...
Since their introduction, fiber posts have been used for restoration of endodontically treated teeth. Despite the development of adhesive techniques in recent years, several studies have shown a significant percentage of adhesive failures at the post/resin cement interface. Thus, the present review addresses different clinical protocols suggested in the literature and new possibilities of surface treatments to improve the clinical performance of fiber posts...

Background: Dengue is the most important human viral disease transmitted by arthropod vectors. The availability of random peptide libraries (RPL) displayed on phage has provided a powerful tool for selecting sequences that mimic epitopes from microorganisms that are useful for diagnostic and vaccine development purposes. In this paper, we describe peptides that resemble the antigenic structure of B-cell epitopes of dengue virus identified from a phage-peptide library using human sera containing polyclonal antibodies against dengue virus. Materials and Methods: Eighteen phage clones were isolated from the phage-display peptide library, J404, by affinity selection using human antisera against dengue virus type 3. These clones were tested for reactivity by ELISA with a panel of hyperimmune ascitic fluids (HAFs) containing antibodies either against all four dengue serotypes, West Nile virus (WNV) or Eastern equine encephalitis virus (EEEV) with control ascitic fluid (NAF) used as a negative control. Results: Eight clones were recognized by HAFs against the four dengue serotypes, of which four significantly inhibited binding of anti-dengue antibodies to the virus. Two peptides with similar sequences to regions of NS3 and NS4B non-structural dengue virus proteins were identified. Conclusion: Our results suggest that these peptides could be used for the development of diagnostic tools for the detection of dengue virus infection and for a potential vaccine against this pathogen.
