Acta literaria , 2008, DOI: 10.4067/S0717-68482008000200003
Abstract: the objective of this paper is to inquire into the modes of representation of space in three chilean science fiction novels published since the end of the eighties. the analysis reveals that the imaginary horizon of the stories could be considered as thought in continuum from city-ghetto -el ruido del tiempo (1987) by claudio jaque- to a totalitarian scene of the city, the cyberspace and the body colonized by information technologies -ygdrasil (2005) by jorge baradit-, including the apocalyptic metropolis, in the process of disintegration of the bicentenary -2010: chile en llamas (1998) by dario oses-.

Abstract: the following paper analyzes the representation of the imbunche, as well as other fragmented or symbiotic beings that are present in the novel ygdrasil (2005) by jorge baradit, as a manner of imagining subjectivities. one of the most important characters of this novel is the religious and syndical leader of a global megacorporation named "el imbunche", from which we can find readings to look for characteristics of monstrosity in the rest of the characters of the novel. this analysis will allow us to conclude that this figure portrays, once more, baradit's productivity, since he uses this strategy to represent the enslaved subject in late capitalism, especially the one that, connected to computer networks, is exposed to the colonization of the body regarding informatics and biotechnology.

Abstract: Indagar en los modos de representación del espacio en tres novelas de ciencia ficción chilena, publicadas desde fines de la década de los ochenta hasta ahora, es el objetivo de este artículo. El análisis revela que el horizonte imaginario de los relatos considerados se desplaza desde la ciudad ghetto -El ruido del tiempo (1987) de Claudio Jaque- al escenario totalitario de la ciudad, del ciberespacio y del cuerpo colonizado por las tecnologías informáticas -Ygdrasil (2005) de Jorge Baradit-, pasando por la urbe apocalíptica, en vías de desintegración del bicentenario -2010: Chile en llamas (1998) de Darío Oses-.

Bestiario ciberpunk: sobre el imbunche y otros monstruos en Ygdrasil de Jorge Baradit Cyberpunk Bestiary: About the Imbunche and other Monsters in Ygdrasil by Jorge Baradit

Abstract: En el presente trabajo se analiza la representación del imbunche, junto a otros seres fragmentados o simbióticos que aparecen en la novela de Jorge Baradit, Ygdrasil (2005), como modos de imaginar las subjetividades. Ello se debe a que uno de los personajes más importantes del relato es el líder religioso sindical de una megacorporación global llamado el Imbunche, lo cual entrega una pista de lectura para buscar las características del monstruo en los restantes personajes. Este análisis nos permite concluir que esa figura muestra nuevamente su productividad, al servirle a Baradit para representar al sujeto esclavizado en el capitalismo tardío y en particular a aquel que, por estar conectado a redes informáticas, está expuesto a la colonización de su cuerpo por la biotecnología y la informática.

Abstract: To evaluate the sensitivity and specificity of the usage of the FMF On-Line Risk Calculator with first-trimester ultrasound, in screening assessment for preeclampsia (PE), without serum markers. To define the best risk cut-off values for early, intermediate and late preeclampsia. Diagnostic accuracy study of pregnant women who had first-trimester ultrasounds between 11 and 13 weeks. The index test was the first-trimester ultrasound scan plus the FMF On-Line Risk Calculator to assess the risk for PE. The reference standard was the confirmation of actual development of early, intermediate or late PE. For calculations of sensitivity and specificity to determine the best cut-off values for early, intermediate and late PE, all the information was processed into ROC curves. The assessment of preeclampsia risk in the first trimester using an ultrasound plus the FMF On-Line Risk Calculator demonstrated a significant (p < 0.05) area under the ROC curve for early, intermediate and late preeclampsia. The best risk cut-off values were defined as 2.1% for early, 2.5% for intermediate and 3.5% for late preeclampsia. The first trimester US plus the FMF On-Line Risk Calculator tool was useful and applicable when assessing the risk for preeclampsia in a specific pregnant Brazilian population.

Abstract: Introducción:Las estimaciones no representativas de la ingesta habitual reducen la validez de una investigación. Objetivos:Determinar qué proporción de un grupo de adultos que practican actividad física en forma recreacional, realizan registros alimentarios de escasa validez para estimar la ingesta energética habitual. Determinar si la validez de la ingesta energética estimada se asocia con determinadas características de los encuestados (so-ciodemográficas y antropométricas entre otras) aterial y Métodos:Estudio transversal analítico. Se incluyeron adultos de 19 a 70 a os, de ambos sexos, que realizaron actividad física programada en 4 establecimientos deportivos en Capital Federal y el Conurbano bonaerense de julio a septiembre de 2009. Se realizaron dos entrevistas, mediciones antropométricas, un registro alimentario de 6 días y un registro de actividad física. Para identificar ingesta estimadas no representativas de la ingesta habitual se utilizó el método de Mc.Crory y col., con un punto de corte ±1DE. Resultados:De los 48 encuestados, el 31,3% (n=15) realizó un registro alimentario compatible con una subestimación de la ingesta energética habitual. El 22,9% (n=11) de los encuestados realizó un registro alimentario que posiblemente sobrestimó la ingesta de energía. La circunferencia de cintura aumentada y el sobrepeso se asociaron con el subregistro (p<0,01), mientras que en el grupo que posiblemente sobrestimó la ingesta había una mayor proporción de individuos con un nivel educativo mayor al secundario completo (p<0,05). Conclusiones:Tanto el sub como el sobre registro estuvieron presentes en este grupo y deben ser tenidos en cuenta al dise ar estudios que utilicen estas herramientas. Introduction:The non representative estimations of regular intake reduce the validity of an investigation. Objectives:To determine which proportion of a group of adults who engage in a recreational physical activity keep food records of poor validity to estimate the regular energy intake. To determine whether the validity of the estimated energy intake is associated with certain characteristics of the respondents (sociodemographic and anthropo-metric, among others) Methods:A cross sectional survey. The participants were adults between 19 and 70 years old, of both sexes, who did scheduled physical activity in four sports facilities in Buenos Aires City and Buenos Aires suburbs from July to September 2009. Two interviews were made, anthropometric measurements were taken, and a 6-day food record and a physical activity record were carried out. In order to identify the

Abstract: En el presente estudio se analizaron por CG-EM (cromatografía de gases-espectrometría de masas) los aceites esenciales de eucalipto (Eucalyptus globulus Labill.), naranja (Citrus sinensis L. Osbeck) y limón (Citrus limon L) y se evaluaron sus efectos tóxicos contra dos especies de plagas importantes para la soja en Sud América: Sternechus subsignatus y Rhyssomatus subtilis. La toxicidad por contacto, ensayada por discos de papel de filtro impregnados, mostró que estos aceites causaron una mortalidad significativa de los insectos testeados (100% de mortalidad a 5 L/cm2). El aceite de eucalipto (98.9 % de 1,8-cineol) presentó la mayor toxicidad por contacto (LD50 = 0.40 y 0.84 L/cm2 para S. pinguis y R. subtilis, respectivamente), mientras que el aceite de naranja (87.6 % de limoneno) y el de limón (62.5 y 12.6 % de limoneno y pineno, respectivamente) fueron menos tóxicos (LD50 > 1 L/cm2 para ambos insectos). Todas las respuestas fueron dosis dependiente. Rhyssomatus subtilis fue más resistente que Sternechus pinguis a la toxicidad de los aceites esenciales estudiados.

Abstract: Background: In recent years, so-called “non-ablative rejuvenation” has been carried out with the use of lasers or intense pulsed light (IPL) to stimulate collagen production by dermal fibroblasts. Intradermal infusion of CO2 stimulates fibroblasts and the synthesis of collagen and elastin, contributing to the retraction of the skin and tissue rejuvenation. Objectives: To evaluate the effects of IPL and the intradermal infusion of CO2 on fibroblast proliferation and collagen in the skin of female rats. Methods: Sixteen adult female Wistar rats were divided into two groups of eight animals. Group 1 underwent IPL and group 2 underwent intradermal CO2 infusion. There was a total of 8 weeks of treatment. We conducted a punch in each animal before any procedure (T0), another punch in the middle of treatment at 4 weeks post-procedure (T1) and a punch at the end of treatment at 8 weeks post-procedure (T2). The cells involved in inflammation, fibrosis and vascularization of the injured tissue by histopathology were analyzed. Results: There was statistically significant fibroblast proliferation and collagen proliferation noted when analyzing all 16 animals together and also when considering the two study groups separately. In both groups, the greatest proliferation of fibroblasts coincided with periods of increased collagen production. Conclusion: Both IPL and intradermal CO2 infusion stimulated fibroblast and collagen proliferation in the skin of the rats studied.
