Abstract: the malignant neuroleptic syndrome is a rare complication associated with the use of antipsychotic agents. the established clinical picture includes taking of consciousness, generalized rigidity and disautonomies associated with rhabdomyolysis with elevated creatine kinase. the case of 3l-year-old male patient with history of delirious hallucinatory episodes at 7, 2l and at present is reported. the first symptoms began 2 months before his admission, with auditive hallucinations. he was treated with haloperidol, but as his psychotic condition did not improve and he was very aggressive, it was decided to administer chlorpromazine, too. a month later, he had fever and respiratory manifestations. after some days, fever increased and axial rigidity and sialorrhoea appeared. he was transferred to the intensive care unit with the diagnosis of malignant neuroleptic syndrome. he received specific treatment and died 3 days later. it was concluded that the malignant neuroleptic syndrome is a rare and very severe neurological complication with a high mortality in those cases that are not treated early.

Abstract: La Antártica se caracteriza por presentar condiciones ambientales extremas, lo cual limita el establecimiento de las plantas vasculares. Dentro de dichas características ambientales están las bajas temperaturas, corta estación de crecimiento y el estrés hídrico y nutricional. La baja disponibilidad hídrica ha sido sugerida como la principal limitante para el éxito de establecimiento, debido a que afecta de manera negativa las respuestas fisiológicas y reproductivas de las plantas. Colobanthus quitensis (Kunth) Bartl. (Caryophyllaceae) es una de las dos plantas vasculares nativas que habitan la Antártica Marítima y se ha demostrado que su desempe o fisiológico y reclutamiento es afectado negativamente por el estrés hídrico del suelo. La plasticidad fenotípica y la adaptación local serían dos de las principales estrategias de C. quitensis para lidiar con las adversas condiciones ambientales que predominan en el continente antártico. Se ha documentado que, bajo un escenario futuro de cambio climático, la disponibilidad hídrica en la Antártica aumentaría entre un 30-40%, mejorando las condiciones para el establecimiento. En el presente trabajo evaluamos mediante un experimento de jardín común, realizado en cámaras de crecimiento, la plasticidad morfo-fisiológica y el esfuerzo reproductivo en individuos de C. quitensis provenientes de dos sitios en las Islas Shetland, bajo un escenario simulado de cambio climático (aumento en un 40% de la disponibilidad hídrica) y bajo la situación actual (disponibilidad hídrica registrada en los sitios de origen). En general, los individuos de C. quitensis de ambos sitios presentaron evidencia de plasticidad, aumentando su eficiencia fotoquímica, largo y ancho foliar, y esfuerzo reproductivo bajo la condición de aumento en la disponibilidad hídrica. La magnitud del aumento en la respuesta plástica fue mayor en aquellos individuos provenientes del sitio más árido en comparación a sus con-específicos del sitio más húmedo. Si los actuales patrones de cambio climático se mantienen, las condiciones abióticas podrían volverse más favorables para C. quitensis, mejorando su desempe o ecofisiológico y permitiendo la expansión de su rango de distribución sobre la Antártica. Antarctica is characterized by extreme environmental conditions, which limit the establishment of vascular plants. These environmental conditions include low temperatures, short growing season and shortage of water and nutrients. Low water availability has been suggested as the main constraint to successful establishment, because it adversely affects the reproducti

Abstract: El síndrome neuroléptico maligno constituye una complicación infrecuente asociada con el uso de neruolépticos. El cuadro establecido tiene toma de conciencia, rigidez generalizada, disautonomías asociadas con rabdomiólisis con creatinin fosfoquinasa elevada. Se presenta un paciente del sexo masculino de 31 a os de edad, con antecedentes de cuadros delirantes alucinatorios a los 7 a os, a los 21 y el actual. Los primeros síntomas comenzaron 2 meses antes de su ingreso, con alucinaciones auditivas. Comienza tratamiento con haloperidol; al no mejorar el cuadro psicótico y estar muy agresivo deciden asociarle clorpromazina. Un mes después presenta fiebre y manifestaciones respiratorias. Días después empeora la fiebre, aparece la rigidez axial y la sialorrea. Es trasladado a cuidados intensivos con el diagnóstico de síndrome neuroléptico maligno, comienza tratamiento específico, no obstante fallece a los 3 días. Se concluye que el síndrome neuroléptico maligno es una complicación neurológica infrecuente pero muy grave, con una elevada mortalidad en los casos no tratados de manera precoz.

Formación de la personalidad autoritaria en Colombia y la exclusion y violencia contra el sujeto etnicamente diferente
González,Jaime Torres;
Análisis Político , 2011,
Abstract: the article presents - following the arguments of wel l- known intellectual authorities- the historic formation of the authoritarian personality of important groups of the colombian elites, molded by strong racist prejudices and under the aegis of the colonial hispanic ideology, religious scholasticism and ethnic prejudices, largely spread in europe. the resistance and struggles undertaken by the non-white majorities have made, in recent times, reduce the degree of racist pressure that had globally decreased with the fall of nazism and, in colombia, with the end of the period domestically called "the violence". however, the persistence of a latent racism in the collective unconscious of ample sectors of the population - the elites and masses, as well - allows the persistent violent waves in the country to continue perceiving areas, primarily inhabited by dark skin populations, main targets for their abuses. the policies of social inclusion, awareness of "the other", improvement of civil, cultural and social rights inherent to a democracy, still have a long road to be run.

Formación de la personalidad autoritaria en Colombia y la exclusion y violencia contra el sujeto etnicamente diferente Formation of the autoritarian personality in Colombia, and exclusion and violence against the ethnically different individual

Análisis Político , 2011,
Abstract: El Artículo presenta -siguiendo el discurso de conocidas figuras- la formación histórica de la Personalidad Autoritaria de importantes grupos de las élites colombianas, moldeada por fuertes prejuicios racistas y bajo la tutela de la ideología colonial hispana, del escolasticismo religioso y de prejuicios étnicos ampliamente difundidos en Europa. La resistencia y las luchas que las mayorías no blancas han dado, han logrado en tiempos recientes reducir el grado de presión racista, que disminuyó a nivel global con la caída del Nazismo, y en Colombia con la terminación del período de "la Violencia". Sin embargo, la persistencia de un "racismo latente" en el inconsciente colectivo de amplias capas de la población -tanto de las élites como del común-, facilitan que las oleadas persistentes de violencia en el país sigan considerando a las áreas con poblaciones de piel mayoritariamente oscura, como objetivos privilegiados de sus atropellos. Las políticas de inclusión social, de reconocimiento "del otro", de ampliación de los derechos individuales, culturales y sociales inherentes a una democracia, tienen todavía un largo camino por recorrer.

Preferencias individuales y elección social. La inocencia epistémica de las teorías
Torres González, Obdulia
Isegoría , 2003,
Abstract: The economic approach, that actually prevail in the social choice studies, have no want consequence when is used in choice of possible social states. The basic reason is that economic model proscribe any axiological consideration in this field, removing in agent's design, ethics and political consideration and any reference about individual's values in the take of collective decisions process. El enfoque economicista que predomina actualmente en el campo de la elección social tiene consecuencias indeseadas cuando se aplica en las elecciones de los posibles estados sociales, es decir, en las elecciones colectivas no económicas. La razón fundamental es que el uso del modelo económico proscribe cualquier consideración axiológica en el terreno de la elección, eliminándose de un plumazo, en el dise o de los agentes, las consideraciones éticas y políticas, y cualquier referencia acerca de los valores de los individuos en el proceso de toma de decisiones colectivas.
Random Matrix Approach to Correlation Matrix of Financial Data (Mexican Stock Market Case)  [PDF]
Juan Martín Casillas González, Antonio Alatorre Torres
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.69099
Abstract: The main purpose of this work is to reproduce the method used for U.S. market which consists in the approach of random matrices to crossed correlation matrices built with financial data taken from a Mexican stock market database. First we built a cross correlation empirical matrix with these financial data. Eigenvalue spectrum was obtained from this matrix. We made the same spectrum analysis for a random matrix, and finally we compared both eigenvalue sets, and we tried to set up a hypothesis of how risk was related to this random matrix-correlation matrix approach. We used financial data over a period of six months and time series where made upon three hours measures for crossed correlation matrix.
Linking Climatic Variability with Spatial Performance in Two Varieties of Quinoa Distributed in a Semi-Arid Zone  [PDF]

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.312205
Abstract: Different crop varieties can respond in different ways to the climatic variations at local scale. Thus, in order to maximize the yield for a determined crop, the response of different varieties submitted to local climatic conditions should be assessed. The main goal of this study was to evaluate the ecophysiological responses of two varieties of Quinoa (PRP and BO78) submitted to different conditions of thermal amplitude. We performed two experiments in both greenhouse and in 3 sites on experimental-field where were evaluated survival, photochemical efficiency, plant growth and dry biomass in both varieties and compared them with the mean of the thermal conditions recorded during the last 16 years in the Coquimbo Region, Chile. Overall, individuals of BO78 showed higher performance in the sites with lower thermal amplitude than those of PRP. By contrast, in sites with higher thermal amplitude individuals of PRP showed better survival, physiological performance and biomass and therefore higher performance. Our results suggest that while BO78 showed an ecotypic strategy, the PRP showed a plastic strategy to maintain higher performance in sites with moderate and high climatic variability. We consider that under an increase in desertification, semi-arid areas would be available for stress tolerant crops like Quinoa, but the success for the food security in these regions may depend upon the variety used.
