Abstract: El Instituto de Investigaciones Agropecuarias (INIA), en su Centro Regional de Investigación (CRI) Quilamapu, ubicado en la ciudad de Chillán, como parte del programa de mejoramiento de frutos de nuez, introdujo 18 de los cultivares comerciales más importantes de casta a desde Italia, Francia y Japón, a mediados de la década del 90. La mayoría de los cultivares introducidos pertenecen a la clasificación marrón, siendo ésta la primera vez que cultivares comerciales de fruto de alta calidad de casta o europeo (Castanea sativa Mill.) tipo marrón, de casta o japonés (Castanea crenata Sieb et Zucc.), e híbridos eurojaponeses (C. crenata x C. sativa) son introducidos al país. Luego de cumplir dos a os de cuarentena, el material fue liberado e injertado en portainjertos de semilla en el CRI Quilamapu. La mayoría de los cultivares iniciaron su producción al segundo a o de establecidos, el a o 2002, y su comportamiento agronómico está siendo evaluado anualmente. La calidad del fruto de la mayoría de los cultivares fue excelente, y cumplen los requisitos para ser clasificados como marrón según el sistema francés o italiano. Los cvs. más promisorios fueron Marrone di Citta di Castello, Marrone di Marradi y Marrone di Val di Susa que expresaron una alta calidad de fruto. La precocidad de los cultivares híbridos eurojaponeses fue superior a la expresada por selecciones locales, iniciándose la cosecha a inicios de marzo. A partir del a o 2002 todos los cultivares se encuentran en evaluación en ensayos de adaptación desde la VII a la X Región del país, área con alto potencial para el cultivo de ambas especies. El presente trabajo constituye la primera introducción de cultivares tipo marrón de casta o europeos, híbridos eurojaponeses y cultivares japoneses a Chile.

La nutrición enteral precoz en el enfermo grave
García Vila,B.; Grau,T.;
Nutrición Hospitalaria , 2005,
Abstract: enteral nutrition has demonstrated to be a useful and safe method to nourish critically ill patients admitted to the intensive care unit. although the time a severely ill patient can stand without nutrition is unknown, accelerated catabolism and fasting may be deleterious in those patients, and the more common recommendation is to start on artificial nutrition when a fasting period longer than seven days is foreseen. at an experimental level, advantages of enteral nutrition over parenteral nutrition are evident since the use of nutritional substrates via the gastrointestinal tract improves the local and systemic immune response and maintains the barrier functions of the gut. clinical studies have demonstrated that early enteral nutrition administered within the first 48 hours of admission decreases the incidence of nosocomial infections in these patients, but not the mortality, with the exception of special groups of patients, particularly surgical ones. the major inconvenience of enteral nutrition is its digestive intolerance and the transpyloric approach, necessary when there is gastroparesia. its efficacy is also questioned when the patient has tissue ischemia. for early enteral nutrition to be effective, a treatment strategy must be implemented that includes from simple measures, such as uprising the bed headrest, to more sophisticated ones, such as the transpyloric approach or the use of nutrients with immunomodulatory capabilities. to date, the use of early enteral nutrition is the best method for nutritional support in this kind of patients provided that it is individualized according to each patient clinical status and that is done following an adequate therapeutic strategy.
La nutrición enteral precoz en el enfermo grave Early enteral nutrition in the critically-ill patient

Nutrición Hospitalaria , 2005,
Abstract: La nutrición enteral se ha demostrado como un método eficaz y seguro de nutrir a los enfermos graves ingresados en una Unidad de Cuidados Intensivos. Aunque se desconoce cuánto tiempo puede estar un enfermo grave sin nutrición, el catabolismo acelerado y el ayuno pueden ser deletéreos en el enfermo grave y la recomendación más frecuente es la de empezar la nutrición artificial cuando se prevea un período de ayuno superior a los siete días. Las ventajas de la nutrición enteral sobre la nutrición parenteral son evidentes a nivel experimental inmune tanto local como sistémica y mantiene las funciones de barrera del intestino. Estudios clínicos han demostrado que la nutrición enteral precoz, administrada en las primeras 48 horas de ingreso, disminuye la incidencia de infecciones nosocomiales en estos enfermos aunque no la mortalidad, salvo en grupos concretos de pacientes, especialmente en enfermos quirúrgicos. El mayor inconveniente de la nutrición enteral es su intolerancia digestiva y el abordaje trans-pilórico, necesario cuando se produce gastroparesia. También existen dudas de su eficacia cuando el enfermo está en situación de isquemia tisular. Para que la nutrición enteral precoz sea eficaz hace falta instaurar una estrategia terapéutica que incluye tanto medidas sencillas como la elevación del cabecero de la cama, a medidas más sofisticadas como el abordaje trans-pilórico o el uso de nutrientes con capacidad inmunomoduladora. El uso de nutrición enteral precoz es, hoy por hoy, el mejor método de soporte nutricional en estos enfermos si se individualiza su uso en función de la situación clínica de cada paciente y se realiza mediante una estrategia terapéutica adecuada.

Band gap control via tuning of inversion degree in CdIn$_2$S$_4$ spinel

Physics , 2012, DOI: 10.1063/1.3692780
Abstract: Based on theoretical arguments we propose a possible route for controlling the band-gap in the promising photovoltaic material CdIn$_2$S$_4$. Our \textit{ab initio} calculations show that the experimental degree of inversion in this spinel (fraction of tetrahedral sites occupied by In) corresponds approximately to the equilibrium value given by the minimum of the theoretical inversion free energy at a typical synthesis temperature. Modification of this temperature, or of the cooling rate after synthesis, is then expected to change the inversion degree, which in turn sensitively tunes the electronic band-gap of the solid, as shown here by accurate screened hybrid functional calculations.

Abstract: primary cilliary dyskinesia (pcd) is an heterogeneous genetic disease caused by a structural and/or functional alteration of the ciliary skeleton. it is a diagnostic challenge due to its protean clinical presentation and to the complexity of screening and diagnostic methods. the method hitherto regarded as the gold standard is the analysis of ciliary structure by transmission electron microscopy (tem). this presents limitations because analyzes a limited number of ciliary axonemes, and may exclude cases with typical functional and clinical presentation. in recent years new diagnostic methods have been developed based on novel knowledge of the structural ciliary proteins, the genes encoding these proteins and mutations associated to dcp. these new methods include genetic analysis and the study of protein expression in cilia of the affected patients. this paper reviews dcp pathophysiology, the current diagnostic methods applied, and summarizes the international literature regarding the diagnosis of dcp based on genetic screening.
Diagnóstico genético en disquinesia ciliar primaria: Revisión bibliográfica Genetic diagnosis in primary ciliary dyskinesia: Literature review

Revista de Otorrinolaringología y Cirugía de Cabeza y Cuello , 2011,
Abstract: La disquinesia ciliar primaria (DCP) corresponde a una enfermedad genética heterogénea, que se produce por una alteración estructural o funcional de los cilios. Es de difícil diagnóstico tanto por su variada sintomatología como por la existencia de métodos de screening y diagnóstico complejos. El método que hasta ahora ha sido considerado como gold standard es el análisis de la estructura ciliar por medio de la microscopía electrónica de transmisión (MET). Esta técnica tiene limitaciones porque permite analizar un número limitado de axonemas ciliares y puede excluir del diagnóstico a pacientes con axonema normal pero con alteración funcional y clínica clásicas. En los últimos a os se han desarrollado métodos diagnósticos sobre la base de un mejor conocimiento de la estructura proteica de los cilios, de los genes que codifican estas proteínas y de las mutaciones asociadas a DCP. Estos nuevos métodos consisten en un análisis genético y un estudio de la expresión de proteínas ciliares en los pacientes afectados. Esta publicación tiene como objetivo realizar una revisión de la fisiopatología de la DCP, los métodos diagnósticos actuales y resumir el desarrollo del diagnóstico genético en la literatura internacional y su posible aplicación en nuestro medio.

Revista de la Sociedad Espa?ola del Dolor , 2008,
Abstract: El más conocido de los procedimientos que intenta una estimación cuantitativa del dolor es el Cuestionario de Dolor de McGill (MPQ). El presente estudio tuvo como objetivo evaluar una versión abreviada del mismo para lo que se determinó si se encontraban asociaciones significativas con el tipo de dolor, variables sociodemográficas y niveles de ansiedad y depresión. La muestra fue de 127 pacientes con diversos tipos de dolor crónico a los que se aplicó el Inventario de Ansiedad Rasgo-Estado de Ch. Spielberger y el Inventario de Depresión de Beck, además de la prueba estudiada. Los resultados mostraron que la selección de los descriptores no estaba asociada a variables sociodemográficas y sí al tipo de dolor, y se encontraron asociaciones significativas con la ansiedad y depresión, lo que habla a favor de la pertinencia de esta versión para la evaluación de pacientes cubanos con dolor crónico. The Mc Gill Pain Questionnaire (MPQ) is the most known inventary to evaluation pain. The aim of this study was assess the utility of MPQ in 127 cuban chronic pain patients . The instruments were a short version of MPQ, the State-Trait Anxiety Inventory (IDARE) and the Beck Depression Inventory (BDI). No significant associations were found with sex, age, scolarship and occupation. Significant associations were found with anxiety, depression and another clinical characteristics.
Z' Decays into Four Fermions
F. del Aguila,B. Alles,Ll. Ametller,A. Grau
Physics , 1992, DOI: 10.1103/PhysRevD.48.425
Abstract: If a new $Z'$ is discovered with a mass $\sim 1 \ TeV$ at LHC/SSC, its (rare) decays into two charged leptons plus missing transverse energy will probe the $Z'$ coupling to the lepton doublet $(\nu,e)_L$ and to $W^+W^-$, allowing further discrimination among extended electroweak models.
Pensamiento moral en Teología y Vida: Imperativo de renovación surgido del Concilio Vaticano II
Concha B.,Pablo;
Teología y vida , 2000, DOI: 10.4067/S0049-34492000000300012
Abstract: how has the challenge of renewing moral theology -issued in the second vatican council- been met in the pages of teología y vida. it would seem that, in the first place, the task of theological and moral reflection undertaken during the forty years of teología y vida may be characterized as providing a privileged space for reflection. a space for reflection built on moral, on the new circumstances and problems confronting christian life from the dynamics generated by the council. the thematic progression of the articles on moral published in the journal has been conditioned by the consirable significance of ecclesiastic (e.g. medellín, puebla, humanae vitae), social (e.g. the divorce issue; questions raised about population growth; the human rights situation in chile and latin america) and scientific (e.g. the contraconceptive pill, the medical capacity of inducing death; the questioning about the origin of life) developments, mandatory reference topics of theological reflection at the present time. both their thematic consistency and sequence, as a key to their primary intentionality, are to be sought not as much in the way moral has undergone a renewal during these forty years of church life, as in the concerns and hardships of men and women who have had to experience this renewal.
