CHOLANGIOCARCINOMA IN A HORSE COLANGIOCARCINOMA EN UN EQUINO
Gomez Nieto Diego Eder,Oliver Espinosa Juan Olimpo
Revista de la Facultad de Medicina Veterinaria y de Zootecnia , 2008,
Abstract: This article is the first report of equine cholangiocarcinoma in Colombia. A 14 years old horse was referred to the Large Animal Clinic at the National University of Colombia, with history of weight loss; on examination, the horse was letarghic, in poor body condition, with abdominal distention and ventral edema. The clinical examination suggested a hepatic tumor as a very probable diagnosis; the clinical pathology results showed severe involve -ment of biliary ducts and hepatic cells. The necropsy and the microscopic examen revealed cholangiocarcinoma. Este art -culo representa el primer reporte de colangiocarcinoma en un equino en Colombia. Esta neoplasia fue diagnosticada en un equino de 14 a ±os de edad remitido a la Cl -nica de Grandes Animales de la Universidad Nacional de Colombia, con historia de p rdida de peso cr 3nica. En la evaluaci 3n cl -nica se encontraron como hallazgos m s relevantes depresi 3n, condici 3n corporal pobre, distensi 3n abdominal severa y edema ventral; se plante 3 como diagn 3stico diferencial m s probable tumor hep tico; los resultados de laboratorio revela -ron severo compromiso de conductos biliares y hepatocitos. En la necropsia e histopatolog -a se confirm 3 el diagn 3stico de colangiocarcinoma.

Clinical Evaluation of an Oral Electrolyte Solution Formulated Based on Strong Ion Difference (SID) and Using Propionate as the Organic Anion in the Treatment of Neonatal Diarrheic Calves with Strong Ion Acidosis  [PDF]
Henry Stampfli, Olimpo Oliver, John K. Pringle
Open Journal of Veterinary Medicine (OJVM) , 2012, DOI: 10.4236/ojvm.2012.21006
Abstract: Background: It is postulated that the concentrations of the major strong ions (Na, K, and Cl) in oral electrolyte solutions play a major role in clinical efficacy of these solutions for rehydration and corrections of metabolic acid base derangements. Objectives: The purpose of this study was to test prospectively the efficacy of an OES (OESexp) formulated based on concentration of strong ion difference (SID) and propionate in a group of calves with naturally occurring neonatal diarrhea and clinically detectable dehydration and acid base abnormalities. Animals: Ten client owned calves of varying breeds, 2 - 22 days old, presented to a veterinary teaching hospital with a history of naturally occurring acute undifferentiated diarrhea, progressive depression and dehydration for treatment. Methods: Clinical and laboratory parameters were measured pre and post two oral electrolyte treatments to assess efficacy of the experimental OES to correct clinical and clinico pathological parameters. For the clinical trial the calves served as their own controls. For control of safety of medication 4 normal calves were force fed 4 L of OESexp and followed over a 24 hour period. Results: All calves had severe diarrhea and metabolic acidosis. The metabolic acidosis observed in the plasma of these calves and reflected by pH, HCO3- SID and base deficit was corrected significantly towards reference ranges (p < 0.05) with two 2 L feedings 12 hours apart. Dehydration was significantly corrected and all calves were discharged 1 - 3 days post admission. Conclusion and Clinical Importance: The use of SID is a valid approach when formulating oral electrolytes solutions for use in calves with acute diarrhea and metabolic derangement. Sodium propionate is valid substitute for commonly used sodium base equivalents in North America in oral electrolyte solutions.

Revista MVZ Córdoba , 2012,
Abstract: Objetivo. Determinar los agentes infecciosos asociados causalmente a la presentación de Diarrea Neonatal Bovina (DNB) en terneros menores de 5 semanas de vida, procedentes de fincas lecheras y de producción mixta de la Sabana de Bogotá. Materiales y métodos. Se seleccionaron por conveniencia 21 fincas, se realizó seguimiento de 620 terneros desde el nacimiento hasta las 5 semanas de edad, se tomaron muestras de materia fecal de los animales que presentaron cuadro clínico de diarrea y de terneros clínicamente sanos como controles pareados. Se realizaron pruebas de ELISA para diagnóstico de E.coli F5, Rotavirus, Coronavirus, Cryptosporidium sp., y Salmonella sp., prueba de Ritchie para diagnóstico de Giardia sp., y tinción de Ziehl Neelsen modificada para Cryptosporidium sp. Se evaluó la asociación epidemiológica entre los agentes y la presentación de diarrea usando prueba de c2, seguido de un modelo de regresión logística (p<0.05). Resultados. Se encontró en la prueba de ELISA que de la totalidad de las muestras, 51 (38.3%), 26 (19.7%), 10 (7.5%) y 1 (0.75%) fueron positivas a Cryptosporidium sp., rotavirus, E coli F5 y coronavirus, respectivamente. Los animales positivos a Rotavirus por la prueba de ELISA y a Cryptosporidium sp., por la técnica de Ziehl Neelsen modificada tuvieron 2.6 y 7.0 veces mayor probabilidad que los demás animales de presentar DNB, respectivamente. Conclusiones. Los resultados presentados son los primeros que muestran el papel y la importancia del Cryptosporidium sp., y del Rotavirus en la DNB en las explotaciones ganaderas de la Sabana de Bogotá y en Colombia.
EVALUACIóN SOBRE LOS PERFILES DE INGRESO DE LOS ALUMNOS DE LOS POSGRADOS DE ADMINISTRACIóN: ACTITUDES Y EXPERIENCIAS HACIA LAS MATEMáTICAS
Edgar Oliver Cardoso Espinosa
PROFESORADO , 2012,
Abstract: Este artículo presenta los principales resultados de la investigación realizada sobre los perfiles de ingreso de los alumnos de los posgrados en administración impartidos en el Instituto Politécnico Nacional (IPN) con la finalidad de identificar sus actitudes y experiencias hacia la asignatura de matemáticas. Los programas seleccionados fueron: 1) Maestría en Administración de Negocios (MAN); 2) Maestría en Administración Pública (MAP) y, 3) Maestría en Administración en Gestión y Desarrollo de la Educación (MAGDE). El instrumento utilizado fue un cuestionario organizado tanto con preguntas cerradas como de tipo Likert. Las principales conclusiones fueron que los alumnos de posgrado presentan una actitud negativa hacia las matemáticas y sus experiencias de aprendizaje más desagradables han sido en el nivel de preparatoria. Además, los estudiantes perciben a esta asignatura como una disciplina útil pero difícil, así como manifestaron actitudes de desconfianza y de ansiedad en las situaciones que involucran el empleo de los procedimientos matemáticos.
MEANINGFUL VARIABILITY: A SOCIOLINGUISTICALLY-GROUNDED APPROACH TO VARIATION IN OPTIMALITY THEORY
Juan Antonio Cutillas Espinosa
International Journal of English Studies (IJES) , 2004, DOI: 10.6018/ijes.4.2.48021
Abstract: Most approaches to variability in Optimality Theory have attempted to make variation possible within the OT framework, i.e. to reformulate constraints and rankings to accommodate variable and gradient linguistic facts. Sociolinguists have attempted to apply these theoretical advances to the study of language variation, with an emphasis on language-interna1 variables (Auger 2001, Cardoso 2001). Little attention has been paid to the array of externa1 factors that influence the patterning of variation. In this paper, we argue that some variation pattems-specially those that are socially meaningful- are actually the result of a three-grarnmar system. G, is the standard grammar, which has to be available to the speaker to obtain these variation patterns. G; is the vernacular grammar, which the speaker is likely to have acquired in his local community. Finally, G, is an intergrammar, which is used by the speaker as his 'default' constraint set. G is a continuous ranking (Boersma & Hayes 2001) and domination relations are consciously altered by the speakers to shape the appropriate and variable linguistic output. We illustrate this model with analyses of English and Spanish.
LEARNING THE PHONOLOGY OF A LANGUAGE: AN OPTIMALITY THEORY APPROACH
Juan Antonio Cutillas Espinosa
International Journal of English Studies (IJES) , 2001, DOI: 10.6018/ijes.1.1.47821
Abstract: Tesar & Srnolensky's book is a valuable reference for traditional approaches to leamability within an Optimality Theory framework. It summarises the reflections of two of the 'founder members' of the discipline. However, other researchers have developed altemative algorithms based on the previous work presented in Tesar & Smolensky which, in our opinion, are more realisfic insofar as they can cope with variation and developmental instability (Boersrna & Hayes 2001). Another interesting question, which affects all computational approaches to leamability, is whether such theories are really grounded or not. Now we know that computers can actually work out the constraint ranking of a language starting frorn some (but not al]) initial hierarchies, provided that they are given sufficient overt information. Does that really mean that this is the way the human mind works?. We cannot be satisfied with a simple statement of the type 'if the hurnan mind performed these operations, it would acquire a language'. The only possible answer is that further research on phonological acquisition must be carried out in order to test whether RIPICD and EDCD are indeed at work in phonological acquisition by human beings. Tesar & Srnolensky's Learnability in Opfimality Theory is possibly a must for phonologists. But insofar as the developrnent of OT seems to have wider implications to the extent of having become a revolution in linguistic theory, it is also recomended for linguists in general and specially for applied linguists with some interest in phonological acquisition.
Tiempo y aspecto verbal. Marco teórico para la clase de ELE
Juan Manuel Real Espinosa
MarcoELE : Revista de Didáctica , 2005,
Abstract: En el presente trabajo se analizan las relaciones temporales y aspectuales del verbo en espa ol. Se defiende que el tiempo es una categoría gramatical pertinente con un comportamiento constante en los modos indicativo y subjuntivo, y que se estructura mediante dos pares de oposiciones binarias, que dan lugar a dos niveles o segmentos temporales y a cuatro áreas de significación temporal. Los comportamientos que podríamos considerar ajenos a esta norma, generan de forma regular un contenido modal dentro del mensaje, por lo tanto un mismo procedimiento da cuenta de las relaciones temporales y modales. El aspecto se articula de igual modo en dos pares de oposiciones binarias, que generan dos niveles o segmentos aspectuales y cuatro áreas de significación aspectual. La oposición en el segundo nivel de oposición aspectual genera una cronología relativa. Se proponen procedimientos para emplear en el aula de E/LE esta concepción del sistema verbal. //// In the present paper I analyze the relationship in temporal and aspect of the Spanish verbs. I defend that time is a pertinent grammatical category which has a constant comportment in the indicative and the subjunctive, structured through two pairs of binary oppositions, forming two grades or temporal fragments and four areas of temporal meanings. The comportment that could be considered as not being part of the rule generates a regular form of modal contents within the message; therefore, the same procedure explains the relationship between time and mode. The aspect is articulated in the same way in two pairs of binary oppositions which generate to grades or aspect fragments and four areas of aspect meanings. The opposition in the second aspect grade generates a relative chronology. Procedure are to be proposed use this verbal system concept in E/LE classes.
La población de Manila y las capellanías de misas de los espa oles: libro de registros, 1642-1672
Mesquida Oliver, Juan
Revista de Indias , 2010,
Abstract: This study focuses on the characteristics of the capellanías of Manila until 1672. The main source for this work is a registry book of capellanías. The quantitative and qualitative information gathered is useful to study the development of this institution, and to learn new insights on the demography, society, culture, and economy of the Spanish population of Manila during most of the seventeenth century. Among the findings of this study, it stands out the efforts carried out and the difficulties found in order to attain a Creole clergy. Este estudio se centra en las características de las capellanías de Manila hasta 1672. Para ello se utiliza la documentación proveniente de un libro de registros de capellanías. Además de exponer el desarrollo de esa institución, la información cuantitativa y cualitativa recabada sirve para estudiar aspectos demográficos, sociales, culturales y económicos de la población espa ola de Manila durante una buena parte del siglo XVII. Entre las novedades presentadas sobresalen los esfuerzos realizados y las dificultades encontradas para crear un clero criollo.
Incidencia del género y la edad en la creatividad infantil
Espinosa Méndez,Juan Carlos;
Diversitas: Perspectivas en Psicología , 2005,
Abstract: it was studied the creativity in 115 children with the creativity test developed by de zubiría, marlés y ramírez (2003) and it was identified both gender and age incidence in the subject's scores. in addition, it was estimated reliability and validity of this test. the results indicate that gender does not represent a significant effect over test's scores; while the age is a relevant factor in children's creativity processes. recommendations about specificity in the age's score tables to this test are done.
