La inclusión de pacientes es un factor clave en el éxito de un ensayo clínico. Una vez concluida esta fase crítica del estudio, surge otro reto de igual importancia, la retención de los sujetos incluidos. Independientemente del objetivo de los proyectos de investigación, la recolección de datos necesaria solo es posible si una cantidad adecuada y suficiente de los individuos seleccionados conti...

La enteropatía autoinmune (EAI) es una causa infrecuente de diarrea grave asociada a un síndrome disinmune, caracterizado por la presencia de autoanticuerpos y enfermedades autoinmunes. Se revisan, de forma retrospectiva, los pacientes diagnosticados de EAI en nuestro centro desde 1975 hasta 2015. En este periodo se diagnosticaron 8 pacientes. El 75% eran varones. La edad de presentación fue: m...

1. This document has been prepared by the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (CONABIO), Mexico’s CITES Scientific Authority, on the basis of reports from the Centro de Investigaciones en Ecosistemas (CIECO) of the National Autonomous University of Mexico (UNAM), which is the institution entrusted with carrying out the study on “Abundance, distribution and conservat...

Since the year 2000, extracorporeal membrane oxygenation (ECMO) support for cardiac failure has been employed in the post operative care of children at the Centro Cardiovascular de Puerto Rico y el Caribe. Our experience with the application of ECMO had been limited to circulatory support after repair of congenital cardiac lesions. We report the first case in Puerto Rico where ECMO was used suc...

Issues of load combinations of earthquakes and heavy trucks are important contents in multihazards bridge design. Current load resistance factor design (LRFD) specifications usually treat extreme hazards alone and have no probabilistic basis in extreme load combinations. Earthquake load and heavy truck load are considered as random processes with respective characteristics, and the maximum comb...

Goals of this preliminary study are to better understand (1) earthquake performance of wood-frame shear walls carrying gravity loads, compared with walls without gravity load, and (2) performance of walls subjected to a sequence of earthquake motions, compared with walls subjected to a single earthquake. Tests with simulated earthquake ground motions were conducted on 2,440 by 2,440-mm (8 by 8-...

Recent years many authors reported thermal anomaly change around epicenter before earthquake. Some researchers tried to predict the earthquake based on the analysis on the temperature anomaly feature by using satellite thermal infrared data. However the infrared radiation can not pass through the thick-layer cloud, so as to hardly achieve the earthquake monitoring. Microwave is also a kind of t...

The preservation and definition of the correct retrofitting interventions historic masonry buildings represents a relevant topic nowadays, especially in country characterized by high seismicity zones. Considering Italian Cultural Heritage, most these are constructed ancient unreinforced (URM) showed level vulnerability during recent 2009 (L’Aquila), 2012 (Emilia Romagna) 2016 (Centro Italia) ea...

The accuracy of the fi!lite-difference method for generating synthetic seismograms of SH wave propagation in cylindrically symmetric media is discussed. The finite-difference method has the advantage that arbitrary density and velocity fields in the medium may be specified. A point source is generated by a simple transformation of a line source. The accuracy of the finite-difference seismograms...
