Teatro em revolu??o (1959-2010)
Tabares, Vivian Martínez;
Estudos Avan?ados , 2011, DOI: 10.1590/S0103-40142011000200014
Abstract: cuban theater, in its multiple forms of expression, has maintained a dialogue with the country's cultural, social and political life. the development of cuban drama over the last five decades coincides with the period when, after the triumph of the revolution, cuban society engaged in a complex process of learning and building a new order. dramatic creation, comprising both written plays and discourses on acting, is related one way or another with the splendors, bungles and setbacks of revolutionary life through languages and styles that embrace realism and other experimental theatrical trends of the 20th century, such as dance and new technologies. cuban drama is not a complaisant creation, but an art form that, not without problems and with acute critical perspective, enables us, cubans, to reflect about who we are and how we live.

Abstract: a way to sort out questions students migth ask themselves to face the responsability of improving their perfomance in the learning of english as a foreing language is presented. these questions demand reflection and guide to know how to improve the learning strategies. some answers are given aimed at guiding students in the learning process and helping them to solve difficulties, since we cannot address every need or individual query. it is not intended to replace the role of the english professor
Inhibidores de bomba de protones y clopidogrel: Evidencia de interacción farmacológica de gran impacto clínico
Martínez,Ingrid; Coy,Vivian; Otero,William;
Revista Colombiana de Gastroenterologia , 2010,
Abstract: clopidogrel, a thienopyridine, is an antiplatelet drug which currently represents the cornerstone for the treatment of acute coronary events. it is a pro-drug that must be converted at hepatic level into its active form by the cyp2c19 isoenzyme. recently the interaction between proton pump inhibitors and clopidogrel has been widely brought to attention. the competitive inhibition that these generate on the hepatic enzymatic system probably activates clopidogrel, thus causing a decrease in its effectiveness as an antithrombotic. nevertheless, evidence is contradictory, and until now no clinical trials have been performed to clear up doubts. if a ppi is to be used on patients who take clopidogrel, the use of pantoprazole or esomeprazole is recommended because they exert minimal inhibition on cyp2c19.
Inhibidores de bomba de protones y clopidogrel: Evidencia de interacción farmacológica de gran impacto clínico Proton pump inhibitors and clopidogrel: Evidence of a Pharmacological interaction of great clinical impact
Ingrid Martínez,Vivian Coy,William Otero
Revista Colombiana de Gastroenterologia , 2010,
Abstract: Clopidogrel, una tienopiridina, es un antiagregante plaquetario que en la actualidad constituye la piedra angular del tratamiento médico en pacientes que presentan eventos coronarios agudos. Es una prodroga que debe ser convertida en la forma activa a nivel hepático, por la isoenzima CYP2C19. Recientemente, se ha llamado ampliamente la atención sobre la probable interacción entre los inhibidores de la bomba de protones y el clopidogrel por la inhibición competitiva que estos hacen sobre el sistema enzimático hepático activador de clopidogrel, que causa disminución de la eficacia del mismo como antitrombótico. Sin embargo, la evidencia sobre esta interacción es contradictoria y hasta el momento no se han realizado ensayos clínicos para resolver esta duda. Si se necesita utilizar un IBP en pacientes que utilizan clopidogrel, se recomienda el pantoprazol o el esomeprazol por la mínima inhibición que ejercen sobre el CYP2C19.

Abstract: Se presenta una forma de organizar las preguntas que los estudiantes pueden hacerse ellos mismos para enfrentar la responsabilidad de perfeccionar su desempe o en el aprendizaje del inglés como lengua extranjera. Estas preguntas requieren de reflexión y guia para saber cómo mejorar las estrategias de aprendizaje. Se ofrecen algunas respuestas con el objetivo de guiar a los estudiantes en este proceso y ayudarlos a resolver las dificultades, ya que no podemos abordar cada necesidad o interrogante individual. Con esto no se prentende reemplazar el papel que desempe a el profesor de inglés.

The use of shortening in english for specific purposes: A practical review for nurses
Martínez Sánchez,Vivian Amparo; Goenaga Conde,Beatriz;
Educaci?3n M??dica Superior , 2001,
Abstract: shortening as a word building process has become very productive in present day english. abbreviations in nursing have also found a way for professional and quick communication. the main goals of this article, based on actual teaching-learning problems, is to provide some practical activities to give the learners opportunities to get acquainted with and practice abbreviations in an effective and communicative way, and to provide a glossary of the most frequently used abbreviations by nurses
Preformulación de mesilato de dihidroergotoxina, gotas orales
Diduk,Natalia; Rodríguez Orjales,Ileana; Martínez Espinosa,Vivian;
Revista Cubana de Farmacia , 1995,
Abstract: se realizaron estudios para determinar la influencia de diferentes factores: el efecto de varios solventes, del ph, la hermeticidad del envase y la adición de un agente antioxidante con el propósito de recomendar la formulación adecuada del producto. se utilizó la cromatografía líquida de alta resolución con método analítico en dichos estudios, la especificidad del mismo se comprobó en los ensayos previos. como resultado se recomienda emplear en la fomulación de mesilato de dihidroegotoxina, gotas orales, glicerina o etanol como solventes, ajustar el ph en el intervalo 4,5 y 5,5, utilizar un envase hermético y a?adir tiourea como agente antioxidante.
Determinación de levodropropizina en gotas orales por cromatografía líquida de alta resolución
Pérez Gutiérrez,Xiomara; Martínez Espinosa,Vivian;
Revista Cubana de Farmacia , 2002,
Abstract: levodropropizine is a synthetic substance, acting at the peripheral level and which has proved to have an efficient antitussive action. an analytic method was developed and validated by high pressure liquid chromatography to quantify levodropropizine in oral drops at 6 %. the following validation parameters were analyzed: lineality, specificity, precision, accuracy and range, according to what is established by the usp 23 for this assay category. the method developed proved to be lineal, specific, accurate and exact in the studied concentration range; therefore, its use is considered as accessible for the quantification of levodropropizine in the quality control and in the stability study of the oral drops.

García Pe?a,Caridad Margarita; Martínez Espinosa,Vivian;
Revista Cubana de Farmacia , 2005,
Abstract: two analytical methods were validated by ultraviolet chromatography and high performance liquid chromatography for the quality control and stability study, respectively, in the idoxuridine 0.1 % eye drops. in the validation, there were evaluated the parameters of specificity for these ends, system lineality, exactness and accuracy, which was expressed in its 2 forms: repeatability and intermediate precision. the analytical methods proved to be specific, lineal, precise and exact in the interval of the studied concentrations.
Uso de antimicrobianos en pacientes con rotura prematura de membranas y embarazo pretérmino

Abstract: a retrospective, longitudinal and descriptive study was conducted in the maternal hospital of guanabacoa in 1999 among 45 preterm pregnants who presented premature membrane rupture (pmr) in order to study some epidemiological factors as well as the response to treatment with antimicrobial drugs. of the studied variables, vaginal infection was the disease most associated with pmr (31.1 %). the birth route was vaginal in 75.5 %. the predominating apgar (88.8 %) was 7-9, with vigorous infants. 46.6 % of the newborn infants had no complication. 77.7 % of the mothers did not present any complication, either. it was concluded that the combined use of penicillin plus aminoglucosides favors the final result for cases with pmr and prematurity.
