Inoculation of Triatoma Virus (Dicistroviridae: Cripavirus) elicits a non-infective immune response in mice

Background: Dicistroviridae is a new family of small, non-enveloped, +ssRNA viruses pathogenic to both beneficial arthropods and insect pests. Little is known about the dicistrovirus replication mechanism or gene function, and any knowledge on these subjects comes mainly from comparisons with mammalian viruses from the Picornaviridae family. Due to its peculiar genome organization and characteristics of the per os viral transmission route, dicistroviruses make good candidates for use as biopesticides. Triatoma virus (TrV) is a pathogen of Triatoma infestans (Hemiptera: Reduviidae), one of the main vectors of the human trypanosomiasis disease called Chagas disease. TrV was postulated as a potential control agent against Chagas' vectors. Although there is no evidence that TrV nor other dicistroviruses replicate in species outside the Insecta class, the innocuousness of these viruses in humans and animals needs to be ascertained. Methods: In this study, RT-PCR and ELISA were used to detect the infectivity of this virus in Mus musculus BALB/c mice. Results: In this study we have observed that there is no significant difference in the ratio IgG2a/IgG1 in sera from animals inoculated with TrV when compared with non-inoculated animals or mice inoculated only with non-infective TrV protein capsids. Conclusions: We conclude that, under our experimental conditions, TrV is unable to replicate inmice. This study constitutes the first test to evaluate the infectivity of a dicistrovirus in a vertebrate animal model.

Molecular Techniques for Dicistrovirus Detection without RNA Extraction or Purification

Dicistroviridae is a new family of small, nonenveloped, and +ssRNA viruses pathogenic to both beneficial arthropods and insect pests as well. Triatoma virus (TrV), a dicistrovirus, is a pathogen of Triatoma infestans (Hemiptera: Reduviidae), one of the main vectors of Chagas disease. In this work, we report a single-step method to identify TrV, a dicistrovirus, isolated from fecal samples of triatomines. The identification method proved to be quite sensitive, even without the extraction and purification of RNA virus.

Prevención de riesgos laborales y negociación colectiva

Las disposiciones contenidas en la Ley de Prevención de Riesgos Laborales constituyen el mínimo legal que debe de tener cualquier actividad laboral y es el convenio colectivo el que debe de mejorar y desarrollar esas disposiciones. En el presente trabajo se aborda la situación actual de la negociación colectiva desde el análisis de los contenidos de los convenios colectivos en materia de seguridad y salud laboral, valorando en qué medida se cumple la función de mejora y desarrollo de la normativa de seguridad y salud laboral, que la LPRL encomienda a la negociación colectiva. Para ello, su estudio se ha elaborado a partir de una selección representativa de convenios colectivos tanto de ámbito sectorial como de empresa, tomando como universo de referencia la provincia de Guipúzcoa. De los resultados obtenidos, se desprende la escasa preocupación de los convenios colectivos de adaptar y adecuar las normas a las particularidades del sector o empresa y mejora de lo expuesto en la LPRL. Limitándose la gran mayoría a hacer referencias a la legislación vigente.

Clonación, expresión y purificación de la proteína estructural VP4 de la cápside del Virus del triatoma (TrV; Dicistroviridae: Cripaviridae)

Triatoma virus (TrV) es un virus patógeno de Triatoma infestans y otros insectos hematófagos , que son los vectores principales de la enfermedad del Chagas (tripanosomiasis americana) . Esta enfermedad es un grave problema sanitario en muchos países de Latinoamérica , do nde es endé mic a y afecta alrededor de 8 millones de personas. El agente causante de dicha enfermedad es el protozoo parásito Tripanosoma cruzi , que infecta al insecto vector y este a su vez , infecta hospedadores vertebrados cuando se alimenta de su sangre [Rassi et al ., 2010] . Al aumentar el movimiento migracional de las personas , la enfermedad ha logrado exte nde rse a otras regiones y convertirse en un problema de salud en z o nas originariamen te no endémicas [ Gascon et a l ., 2010 ] . Debido a esto se ha propuesto el uso de TrV como agente de control biológico frente a los vectores de la enfermedad del Chagas

Teatro y traducción (inglés-español). Análisis comparativo de traducciones comerciales. Who's Afraid of Virginia Woolf?

El presente trabajo se centra en un análisis comparativo en varios niveles de las traducciones producidas a partir de la obra teatral Who’s Afraid of Virginia Woolf? (Albee 1962): las de Marcelo De Ridder, José Méndez y Alberto Mira, realizadas con distintos fines y en momentos histórico culturales diferenciados. Asimismo hemos integrado en la comparación la adaptación cinematográfica y los correspondientes textos audiovisuales en inglés y en español, con el fin de ofrecer una visión más inclusiva del modo en que se ha generado esta cadena textual. Para manejar el mencionado corpus, nos hemos valido de herramientas informáticas. Por un lado, el programa TRACEAligner ha resultado de gran utilidad para alinear los textos teatrales. Por otro lado, SubRip ha posibilitado la extracción del subtitulado en inglés y en español del DVD, que después hemos organizado en una tabla bitextual. A través de una metodología fundamentada en estudios de investigación relevantes, hemos examinado el corpus desde una perspectiva extratextual, macroestructural, microestructural e intersistémica. Esto nos ha permitido interrelacionar las traducciones en aspectos tan importantes como los factores contextuales que afectan a su producción, las características de las publicaciones (o del libreto inédito), la transferencia de las unidades estructurales y argumentales, la correspondencia con rasgos de distintos tipos de traducciones, los fenómenos de traducción con mayor incidencia o las adaptaciones derivadas de los procesos de censura. Gracias a la comparación de estos temas, se pueden apreciar las características distintivas de cada texto. Otro asunto que se trata a lo largo del análisis es la identificación del texto fuente de cada traducción, especialmente de la de Méndez. Hemos tratado de demostrar que Méndez parte del texto norteamericano, no de la traducción de Ridder, como se ha sugerido (Espejo 1998: 111 112). Por último, recogemos una serie de conclusiones que pretenden verter luz sobre las cuestiones planteadas en la introducción.

Systematic liquidity: commonality and inter-temporal variation in the Portuguese stock market

[EN] The aim of this paper is to study systematic liquidity at the Euronext Lisbon Stock Exchange. The motivation for this research is provided by the growing interest in financial literature about stock liquidity and the implications of commonality in liquidity for asset pricing since it could represent a source of non-diversifiable risk. Namely, it is analysed whether there exist common factors that drive the variation in individual stock liquidity and the causes of the inter-temporal variation of aggregate liquidity. Monthly data for the period between January 1988 and December 2011 is used to compute some of the most used proxies for liquidity: bid-ask spreads, turnover rate, trading volume, proportion of zero returns and the illiquidity ratio. Following Chordia et al. (2000) methodology, some evidence of commonality in liquidity is found in the Portuguese stock market when the proportion of zero returns is used as a measure of liquidity. In relation to the factors that drive the inter-temporal variation of the Portuguese stock market liquidity, the results obtained within a VAR framework suggest that changes in real economy activity, monetary policy (proxied by changes in monetary aggregate M1) and stock market returns play an important role as determinants of commonality in liquidity.

Brand image and lexicographic analysis: an application to shopping malls

[EN] The concept of image in its different aspects is very important in today s society as well as in the business management field. Some authors reports that most of the studies that measure image do not take into account neither previous theoretical and conceptual models nor other possible empirical evidence alternatives. Given this need, a research regarding the concept of brand image applied to shopping malls was conducted based on the conceptual model of the consumer cognitive response in order to empirically explore and contrast it. For this reason, a survey was applied to 420 consumers in five shopping malls in Bogotá, achieving a database of 3.749 cases. The results show attribute-shopping mall associations expressed in unique, differentiated, and notorious vocabulary obtained applying lexicometric and multivariate analysis techniques. Attribute-shopping mall associations such as spacious , good location , good variety of stores , and the existence of movie theaters . Finally, this research aims to potentially improve the management of shopping malls and increase their attractiveness and customer loyalty by applying the development of service quality systems, integral communication, segmentation, and positioning.

Alveolar nitric oxide and its role in pediatric asthma control assessment

Resumen Background: Nitric oxide can be measured at multiple flow rates to determine proximal (maximum airway nitric oxide flux; Jaw(NO)) and distal inflammation (alveolar nitric oxide concentration; CA(NO)). The main aim was to study the association among symptoms, lung function, proximal (maximum airway nitric oxide flux) and distal (alveolar nitric oxide concentration) airway inflammation in asthmatic children treated and not treated with inhaled glucocorticoids. Methods: A cross-sectional study with prospective data collection was carried out in a consecutive sample of girls and boys aged between 6 and 16 years with a medical diagnosis of asthma. Maximum airway nitric oxide flux and alveolar nitric oxide concentration were calculated according to the two-compartment model. In asthmatic patients, the asthma control questionnaire (CAN) was completed and forced spirometry was performed. In controls, differences between the sexes in alveolar nitric oxide concentration and maximum airway nitric oxide flux and their correlation with height were studied. The correlation among the fraction of exhaled NO at 50 ml/s (FENO50), CA(NO), Jaw(NO), forced expiratory volume in 1 second (FEV1) and the CAN questionnaire was measured and the degree of agreement regarding asthma control assessment was studied using Cohen's kappa. Results: We studied 162 children; 49 healthy (group 1), 23 asthmatic participants without treatment (group 2) and 80 asthmatic patients treated with inhaled corticosteroids (group 3). CA(NO) (ppb) was 2.2 (0.1-4.5), 3 (0.2-9.2) and 2.45 (0.1-24), respectively. Jaw(NO) (pl/s) was 516 (98.3-1470), 2356.67 (120-6110) and 1426 (156-11805), respectively. There was a strong association (r = 0.97) between FENO50 and Jaw(NO) and the degree of agreement was very good in group 2 and was good in group 3. There was no agreement or only slight agreement between the measures used to monitor asthma control (FEV1, CAN questionnaire, CA(NO) and Jaw(NO)). Conclusions: The results for CA(NO) and Jaw(NO) in controls were similar to those found in other reports. There was no agreement or only slight agreement among the three measure instruments analyzed to assess asthma control. In our sample, no additional information was provided by CA(NO) and Jaw(NO).
