Data from: Not only for egg yolk - functional and evolutionary insights from expression, selection and structural analyses of Formica ant vitellogeni…

2015

Vitellogenin, a storage protein, has been extensively studied for its egg-yolk precursor role, and it has been suggested to be fundamentally involved in caste differences in social insects. More than one vitellogenin copy has been reported in several oviparous species, including ants. However, the number and function of different vitellogenins, their phylogenetic relatedness and their role in reproductive queens and non-reproductive workers has been studied in few species only. We studied caste biased expression of vitellogenins in seven Formica ant species. Only one copy of conventional vitellogenin was identified in Formica species, and three vitellogenin homologues, derived from ancient …

La introducción de discurso directo por medio del aproximador como en el español de Chile

2021

espanolEn la ultima decada, diversos estudios han dado cuenta de la polifuncionalidad de la particula como en el espanol. Mas alla de su valor semantico aproximador, se ha establecido que como se presenta en el discurso cumpliendo ademas funciones pragmatico-discursivas, como retardacion, atenuacion e introduccion de discurso directo (Holmvik 2011; Jorgensen 2012; Panussis 2016; Mondaca 2017; Panussis y San Martin 2017, Mondaca 2019). En el presente articulo se busca analizar, por una parte, la relacion que existe entre el uso aproximador de como y su funcion de introductor de discurso directo en el espanol de Chile, con el fin de establecer que tipos de informacion son introducidos en esti…

Representaciones sociales a través del lenguaje en la lexicografía hispanoamericana decimonónica

2014

Este articulo parte de una propuesta de analisis relativamente reciente de la primera lexicografia hispanoamericana despues de la independencia, que consiste en asumir una estrecha relacion entre la elaboracion, difusion y recepcion de los primeros diccionarios del espanol americano –en cuanto produccion cultural de la elite criolla–, y los procesos historicos y socio-politicos de la epoca. Sobre esta base, se postula la existencia de una unidad del discurso lexicografico, a pesar de la diversidad de obras y autores, que es posible entrever y caracterizar. Se analizan, en consecuencia, los mecanismos que en este discurso se ponen en funcionamiento para ofrecer representaciones sociales –en …

Un viaje por el infierno, de Alberto Gamboa: escritura testimonial e imaginario de la reconciliación

2015

ResumenEl artí­culo analiza el testimonio Un viaje por el infierno, de Alberto Gamboa,que articuló el imaginario periodí­stico del que provení­a su autor y la escrituratestimonial que habí­a sido de gran importancia en el exilio, pero que habí­a carecido de espacios de expresión en el Chile de la dictadura. El autor analiza el modo en que el testimonio de Gamboa puso en contacto por primera vez las caracterí­sticas enunciativas de las escrituras testimoniales con el imaginario de la reconciliación nacional.Palabras clave: Testimonio, dictadura chilena, reconciliación nacional, libro reportaje Un viaje por el infierno by Alberto Gamboa: testimonial writing and imaginary of the Reconciliation…

Aproximación al estudio de las funciones pragmáticas y a la atenuación en la partícula ‘onda’ en el español de Chile

2020

Resumen En el español de Chile, además de su uso como sustantivo, ‘onda’ cumple también funciones propias de una partícula discursiva. La bibliografía ha determinado que este elemento puede actuar como reformulador explicativo, operador de concreción, operador con valor continuativo o aproximativo e introductor de discurso directo (San Martín, Rojas & Guerrero, 2016). El presente estudio tiene como objetivo, primero, retomar esta propuesta de funciones y profundizar en ella y, segundo, determinar si existen usos de ‘onda’ que se relacionen con un valor pragmático atenuante, partiendo de la hipótesis de que este valor podría surgir a partir sus usos como aproximador y…

Regional variations in Helicobacter pylori infection, gastric atrophy and gastric cancer risk: The ENIGMA study in Chile.

2020

International audience; Background: Regional variations in gastric cancer incidence are not explained by prevalence of Helicobacter pylori, the main cause of the disease, with several areas presenting high H. pylori prevalence but low gastric cancer incidence. The IARC worldwide H. pylori prevalence surveys (ENIGMA) aim at systematically describing age and sex-specific prevalence of H. pylori infection around the world and generating hypotheses to explain regional variations in gastric cancer risk.Methods: We selected age- and sex-stratified population samples in two areas with different gastric cancer incidence and mortality in Chile: Antofagasta (lower rate) and Valdivia (higher rate).

Raising Children in Risk Neighborhoods from Chile: Examining the Relationship between Parenting Stress and Parental Adjustment

2021

Introduction: Parenting stress and parental adjustment could implicate key differences in the relational dynamics that parents establish with their children, particularly when families come from vulnerable social contexts. Method: Participants were 142 fathers and mothers from a risk neighborhood of Chile. The variables examined were parenting stress (parental distress, parent–child dysfunctional interaction and difficult child) and parental adjustment (depression, anxiety, and stress). Parents also completed a sociodemographic characterization survey. The statistical analyses were a correlation analysis and multiple linear regression analyses. Results: Overall, not all components of parent…

Diagnostic value of CD34 immunostaining in desmoplastic trichilemmoma.

1998

Desmoplastic trichilemmoma (DT) is a variant of trichilemmoma, characterized by a central prominent desmoplastic component which may simulate invasive carcinoma. We have studied the morphologic and immunohistochemical features of seven cases of DT. Immunohistochemistry was performed on paraffin sections using monoclonal antibodies to CD34 (QBEND/10), vimentin and GCDFP-15. CD34 was also tested in seven cases of basal cell carcinoma (BCC), three with outer root sheath differentiation and four with morphea-form features, and five squamous cell carcinomas. Histologically, features of conventional trichilemmoma were seen at the periphery of the seven lesions. In contrast, at the center, the epi…
