Revista Cubana de Hematolog?-a, Inmunolog?-a y Hemoterapia , 2006,
Abstract: La lectina de unión a la manosa (MBL) es una colectina que se sintetiza en el hígado y es secretada al torrente sanguíneo, la cual es capaz de unirse con estructuras repetidas de azúcares presentes en una amplia variedad de bacterias y otros microorganismos promoviendo su eliminación mediante la activación del complemento a través de serín proteasas asociadas. A las deficiencias de MBL se les considera como un importante factor de riesgo de infecciones en ni os y en individuos inmunosuprimidos. Se discute la evidencia de que la MBL contribuye de forma importante a la inmunidad innata con el incremento de la susceptibilidad a determinadas enfermedades o la incidencia en el curso de estas. Estudios preliminares del empleo de terapias sustitutivas con MBL han arrojado resultados prometedores, los que deben ofrecer evidencias acerca del significado fisiológico de esta proteína Manosse-binding lectin (MBL) is a colectin that is synthesized in the liver and is secreted to the the blood stream. It is capable of binding to other repeated structures of sugars present in a wide variety of bacteria and other microorganisms, promoting their elimination by the activation of the complement through associated serin proteases. The MBL deficiencies are considered as an important risk factor for infections in children and immunosuppressed individuals. It is discussed the evidence that MBL contributes in an important way to the innate immunity with the increase of susceptibility to certain diseases or the incidence on their course. Preliminary studies on the use of replacement therapies with MBL have yielded encouraging results, which should offer evidences about the physiological significance of this protein

Abstract: se preparó un conjugado con peroxidasa a partir de los anticuerpos específicos aislados de un antisuero de cabra anti igg de ratón (molécula completa). los anticuerpos se aislaron por cromatografía de afinidad y el conjugado se preparó por el método de oxidación con peryodato. el conjugado obtenido presentó una relación molar igg/peroxidasa de 1,31, un valor de rz de 0,285 y resultó evaluado satisfactoriamente en cuanto a su especificidad y reactividad en los ensayos inmunoenzimáticos realizados
Detección de software malicioso para el filtro de contenido Smart Keeper
Yurisleidy Hernández Moya,Daileny Hernández Barreiro,Luis Enrique Sánchez Arce,Juan Carlos Lobaina Guzmán
Revista Cubana de Ciencias Informáticas , 2012,
Abstract: La detección de software malicioso en el filtro de contenido Smart Keeper presenta varias limitantes, tales como: no se consideran las preferencias del cliente respecto al antivirus que este desea emplear, se ignoran los ficheros de gran tama o en la búsqueda de software malicioso y las peticiones de escaneo se procesan únicamente de manera secuencial (lo que puede provocar un incremento en el tiempo de respuesta para el usuario). En la presente investigación se propone el desarrollo de un subsistema que contribuirá a erradicar las deficiencias anteriores. La propuesta se basa en dos elementos fundamentales: el componente para el envío de mensajes (solicitudes de trabajo) y la capa de abstracción que propicia la comunicación con los diferentes antivirus.
Discoursive analysis and pragmatic metadiscourse in four sub-areas of Economics research articles
Concepción Hernández Guerra,Juan M. Hernández Guerra
Ibérica , 2008,
Abstract: English for Specific Purposes (ESP) and English for Academic Purposes (EAP) are two disciplines whose importance has been growing lately. This is due to the ever-increasing interest in the language that describes the most recent developments in varying disciplines and the need to communicate in and understand that language. One of the means for the spreading of those new developments in the different technologies is through research articles inspecialised journals. These impose certain rules that must be fulfilled by all researchers who want to see their papers published. Much literature has been written about this, covering most linguistic areas (see, for instance, Bazerman, 1988; Bhatia, 1993; Dudley-Evans, 1994; Fortanet, 2002). Many articles contrast different genres but rarely distinguish different sub-areas within a genre (Bridgman & Carlson, 1984; Malcolm, 1987; Hyland, 1988; Neff Van Aertselaer, 2006). In the present case, we will consider texts within the discipline of Economics. The aim of this paper is to show a structural, grammatical and metatextual analysis of ten articles recently published in very prestigious specialised publications, covering the most important areas of study in Economics. We conclude by making a contrastive rhetorical analysis of the four sub-genres analysed here. These are: Applied Economy, Quantitative Economy, Financial Economy, and Management and Business.

Revista Cubana de Medicina General Integral , 2010,
Abstract: Se realizó un estudio que comienza prospectivo, pero continúa y termina descriptivo sobre la enfermedad cerebrovascular, con los casos nuevos que fueron tratados en el Servicio de Rehabilitación Municipal de Artemisa en el a o 2008, con el objetivo general de describir los resultados del tratamiento mediato. De un universo de 46 pacientes, la muestra tomada consistió en 25 pacientes, y como la población fue peque a, se tomaron los catalogados como hemiparéticos, para comparar su evolución clínica al cabo de 6 meses de tratamiento normado e individualizado. Para comparar su grado de efectividad se utilizó la dócima de Mc Nemar o método de los 4 cuadros, utilizado en muestras peque as para buscar significación estadística y que los valores obtenidos no se deban al azar. En cuanto a los resultados: de los 14 casos que recibieron tratamiento de rehabilitación en etapas mediatas, 9 de ellos (63,7 %) tuvieron mejoría clínica evidente al pasar al estadio de solo presentar signos neurológicos mínimos (definición operacional de variable). Hubo un predominio del grupo perteneciente al sexo masculino con un total de 30 casos, el 37 % estuvo en edades comprendidas entre 60 y 69 a os, y el estadio clínico de hemiparéticos predominó de todos los casos (54,6 %).

Anticuerpos anticitoplasma de neutrófilos (ANCA): una herramienta importante en el diagnóstico de las vasculitis Antineutrophil cytoplasmic antibodies (ANCA): an important tool for the diagnosis of vasculitis
Ana M Guerreiro Hernández,Rinaldo Villaescusa Blanco,Luz M Morera Barrios,Ada A Arce Hernández
Revista Cubana de Hematolog?-a, Inmunolog?-a y Hemoterapia , 2002,
Abstract: Se determinó la presencia de anticuerpos anticitoplasma de neutrófilos (ANCA) específicos para la proteinaza 3 (cANCA) y la mieloperoxidasa (pANCA) en 166 pacientes, 45 con vasculitis no precisadas y el resto con diferentes enfermedades asociadas con procesos inflamatorios, fenómenos autoinmune e infecciones, mediante inmunofluorescencia indirecta. Se detectó la presencia de cANCA en 12 casos con vasculitis, y pANCA en 8 pacientes con enfermedades autoinmunes y en 14 con anemia drepanocítica. Nuestros resultados sugieren la posibilidad de cierto grado de participación de estos autoanticuerpos en el da o del endotelio vascular que se observa en estas enfermedades, debido a la activación de los neutrófilos The presence of antineutrophil cytoplasmic antibody (ANCA) specific to proteinase 3(cANCA) and myeloperoxidase (pANCA) were determined by indirect immunofluoresce test in 166 patients, 45 of which presented with undetermined vasculitis and the rest with different diseases associated with inflammatory processes, autoimmune phenomena and infections. cANCA were detected in 12 cases with vasculitis whereas pANCA were observed in 8 patients with autoimmune diseases and in 14 with sickle cell anemia. Our results suggest the possibility of some level of involvement of these autoantibodies in the vascular endothelium damage that is observed in these diseases due to neutrophil activation
Analizador Sintáctico de Lenguaje Natural con Reglas Editables para la Generación de Primitivas UML.
Carlos M. Zapata,Juan C. Hernández
Avances en Sistemas e Informática , 2007,
Abstract: We propose, in this paper, a constituent-based automated syntactic analyzer fr om natural language it has capabilities for grammatical rules modification. The parser uses bottom-up method for syntactic tree generation and right-left, left-right verifying for level tree building. The parser itself was built as a part of an application for automatic obtaining of UML primitives from natural language due to this fact, weneed syntactic rules edition for incorporing new phrases and for easing data processing to other analysis modules.
