El contenido típico de la estafa en la doctrina y la jurisprudencia : los tipos penales de los artículos 468 y 473 del Código Penal

Villablanca Meza, Pablo Tomás January 2019 (has links)
Memoria para optar al grado de Licenciado en Ciencias Jurídicas y Sociales / El presente texto aborda el tratamiento más reciente que la doctrina y la jurisprudencia nacional han efectuado respecto del delito de estafa. Se abordarán con especial interés los tipos penales de los artículos 468 y 473 el Código Penal. El objetivo de esta exposición es presentar al lector no especializado las principales discusiones doctrinaras que genera la interpretación de la estafa. En el capítulo primero se presenta la conceptualización de la estafa en la doctrina nacional abordándose los elementos esenciales que constituyen dicha figura. En el capítulo segundo se tratan los tipos penales de los artículos 468 y 473 del Código Penal. En el capítulo tercero se reproducen sucintamente una porción seleccionada de las posiciones adoptadas por tribunales chilenos con competencia en lo penal, respecto de la aplicación e interpretación del delito de estafa. La exposición de los contenidos del presente documento se utiliza un método expositivo descriptivo, ya que se intenta reproducir de la manera más fielmente posible las posiciones adoptadas por los diversos autores consultados y por los tribunales de justicia. En cuanto a la reproducción de casos, ésta se efectúa sobre una muestra de treinta resoluciones judiciales recopilada al azar. El método de reproducción de sentencias consiste en la reproducción o parafraseo de los hechos acreditados por el tribunal, las posiciones de los intervinientes respecto a la calificación jurídica de los hechos, la calificación efectuada por el tribunal, la decisión adoptada. Finalmente se incluye de un brevísimo a modo de resumen. El objetivo principal de esta sección es reproducir las posiciones adoptadas por los tribunales frente a casos concretos de estafa e identificar a que tesis doctrinaria correlativa. Como objetivo secundario se pretende mostrar al lector la calificación que realiza el tribunal entre los artículos 468 y 473 del Código Penal en casos concretos

Phytochemicals from Graviola fruit selectively inhibit breast cancer cells growth involving EGFR signaling pathway

Dai, Yumin 01 June 2010 (has links)
There is a growing interest in using naturally-occurring compounds as cancer chemopreventive or chemotherapeutic agents. This study investigated the anticancer potential of the graviola fruit extract (GFE) on specific human breast cancer (BC) cells. GFE was found in our preliminary screening to selectively inhibit the growth of certain human BC cells (MDA-MB-468) but did not affect non-transformed breast epithelial MCF-10A cells. GFE treatment was very effective against the growth of MDA-MB-468 BC cells with an IC50 of 4.8 µg/ml. In vitro, effects of GFE treatment on MDA-MB-468 BC cells were further examined for apoptosis and cell proliferation. Apoptosis, determined qualitatively and quantitatively, was enhanced and accompanied by caspase-3 activation. GFE treatment also induced cell cycle arrest at the G1 cell cycle phase and significantly reduced the percentage of MDA-MB-468 cells in S-phase following 24h of exposure. Moreover, the results from analysis of the mRNA expression of epidermal growth factor receptor (EGFR), which plays an important role in regulating cell development and death, by qRT-PCR, suggested that GFE-induced selective growth inhibition of MDA-MB-468 BC cells is associated with a significant inhibition of EGFR gene expression in the cells. In vivo, dietary treatment with GFE significantly inhibited MDA-MB-468 tumor growth implanted in mice by reducing tumor wet weight and significantly reduced EGFR and p-ERK protein expression in tumors. Overall, GFE attenuated cell proliferation, induced apoptosis, modulated cell cycle regulation and downregulated EGFR gene expression both in vitro and in vivo. These discoveries support the further studies to fully elucidate the antitumor potential of GFE and its components as a dietary agent for BC. / Master of Science in Life Sciences

A l'affût des variations infinies du chaos : approche de l'oeuve de Rodrigo Fresán / On the lookout for the infinite variations of chaos : approaching the work of Rodrigo Fresán

Bargiel, Ewa 12 December 2014 (has links)
Notre recherche s’intéressera à la composition sophistiquée de ce que nous allons dénommer « la maison livresque frésanienne » ou « série intertextuelle ». À travers notre étude, il s’agira de montrer que les neuf ouvrages de Rodrigo Fresán, sans égard à leurs appartenances génériques et leurs thématiques diverses, forment un tout cohérent et ils ne peuvent pas, par conséquent, être étudiés de façon séparée. Nous mettrons en évidence la continuité, la logique et, surtout, le caractère systématique du projet littéraire unissant tous les livres de l’auteur dans une série intertextuelle unique, fractale et « en devenir ». Eu égard au fait que cette écriture génériquement hybride est caractérisée par une tension entre les techniques d’unification et celles de discontinuité, nous effectuerons une présentation des procédés d’intégration et d’atomisation mis en place dans les collections de nouvelles intégrées et dans les romans de l’auteur. Ensuite, nous dégagerons la stratégie principale d’édification du continuum de la maison livresque : le principe de répétition et de variation. Nous explorerons plusieurs domaines d’application du mécanisme de la répétition/variation à différents niveaux de toute la série. Notre étude sera focalisée notamment sur les structures narratives, la dimension métafictionnelle, les hybridations génériques et les modèles extralittéraires de l’écriture frésanienne, c’est-à-dire ses inspirations musicales, picturales, photographiques, cinématographiques, scientifiques et religieuses. / The aim of this thesis is to examine and interpret the sophisticated composition of Rodrigo Fresán’s “house of books” or “intertextual series”. Our research will demonstrate that the nine books of the Argentinean writer, in spite of their different generic classifications and their significant thematic diversity, form a coherent whole and they cannot be therefore analyzed separately. The continuity, the logic and, most importantly, the systematic nature of this literary project, that unites all the books of the author in an original and fractal intertextual series “in progress”, will be showed. Considering the fact that this work is characterized by a generic hybridity and a tension between the unification and discontinuity techniques, the processes of literary integration and atomization utilized in the integrated story collections and in the novels of the author will be presented. Then, a repetition and variation principle will be investigated as a main construction strategy of this continuum. Many fields of application of the repetition/variation mechanisms on various levels of the series will be explored. Our study will be concentrated mostly on the narrative structures, the metafictional dimension, the generic hybridity and the extraliterary models of the Fresán’s books, that is, his musical, pictorial, photographic, film, scientific and religious inspirations.
