Helicobacter pylori en pacientes con diferentes enfermedades gastroduodenales
Martínez Echavarría,María Teresa; Ferreira Capote,Raúl; González Torres,Maximino;
Revista Cubana de Medicina , 2008,
Abstract: the role played by helicobacter pylori in the development of different digestive diseases has been widely studied and discussed. the presence of this bacterium in biopsy samples obtained by endoscopy was studied. 69 patients with duodenal ulcer, gastric ulcer, chronic gastritis and dyspepsia were investigated. the diagnoses of gastric ulcer and chronic gastritis were histologically confirmed. 27 duodenal ulcers, 12 gastric ulcers, 24 chronic gastritis and 6 dyspepsias were analyzed. the presence of helicobacter pylori was detected through the amplification of a fragment of the ure a gene by polymerase chain reaction in 100 % of the duodenal ulcers, in 100 % of the gastric ulcers, in 83 % of the dyspepsias and in 92 % of chronic gastritis, for a total prevalence of 95.7 %.

Abstract: El papel que desempe a Helicobacter pylori en el desarrollo de diferentes enfermedades digestivas ha sido ampliamente investigado y discutido. Se estudió la presencia de esta bacteria en muestras de biopsia obtenidas mediante endoscopia. Se tomaron 69 pacientes con úlcera duodenal, úlcera gástrica, gastritis crónica y dispepsia. Los diagnósticos de úlcera gástrica y gastritis crónica fueron confirmados histológicamente. Se analizaron 27 úlceras duodenales, 12 úlceras gástricas, 24 gastritis crónicas y 6 dispepsias. Se detectó la presencia de Helicobacter pylori a través de la amplificación de un fragmento del gen Ure A mediante la reacción en cadena de la polimerasa, en el 100 % de las úlceras duodenales, en el 100 % de las úlceras gástricas, en el 83 % de las dispepsias y en el 92 % de las gastritis crónicas, para una prevalencia total del 95,7 %.

Diagnóstico molecular del Síndrome X Frágil en un grupo control y miembros de 3 familias afectadas
Acevedo López,Ana María; Ferreira Capote,Raúl; Gayol Mecías,Luis A.; Méndez del Castillo,Dora;
Revista Cubana de Pediatr?-a , 1996,
Abstract: the fragile x syndrome is the most frequent form of hereditary mental retardation, with an incidence of 1 in 1 500 males, and 1 in 2 500 females; it is caused by mutations that increase the size of a fragment of specific desoxinucleotic acid (dna) in the xq 27.3 region of the x chromosome. the outcome in the introduction and application of the stb12.3 molecular probe in a control group and in affected members of three families, is presented. the x-rays of the southern blot that show the diagnosis patterns possible to obtain, are exposed. this methodology is more direct, effective and reliable for the diagnosis and prevention of this form of mental retardation.

Abstract: se realizó un estudio descriptivo en la población adulta del consultorio 38 del policlínico - hospital "santos suárez" en el a?o 1995 con el objetivo de determinar la prevalencia de obesidad y las enfermedades que se asociaron a este grupo. de los 332 pacientes mayores de 15 a?os de edad se detectaron 60 obesos (18 %) a los cuales se les realizaron diferentes exámenes como: ultrasonido abdominal, electrocardiograma, prueba de tolerancia a la glucosa oral, colesterol total y triglicéridos séricos. además se obtuvieron datos de las historias clínicas familiares. de esta forma se diagnosticaron las principales entidades asociadas con la obesidad.se estableció la relación entre la obesidad y el sedentarismo. se exponen los resultados y se comparan con los reportados en la literatura nacional y extranjera. se aprecia la eficacia de la labor del médico de la familia en acciones de salud de la comunidad y en particular para la obesidad, y se resalta la importancia de pesquisar en este grupo de pacientes las principales afecciones asociadas.
Re-pensando el orden colonial: los intercambios hispano-indígenas en el fuerte del río Negro
Luiz,María Teresa;
Mundo agrario , 2005,
Abstract: the study of cross-cultural processes in the colonial frontiers in latin america shows keys to explain the dynamics of interethnic relationships, acculturation experiences and construction of identities. likewise, the functioning of the colonial order can be analyzed from the ways the power relationships were structured in the areas where the aborigines preserved autonomy and crontrol of their territories and resources. hispanic-native relationships are studied from this theoretical point of view, in one of the last borders where the hispanic expansion got since the bourbon's duty imposed, that is the southernmost territories of río de la plata. analyzing the ways of interaction in the río negro fortress, we identified the hispanic-local and aboriginal strategies and recognize the stabilization of a transaction assemblage that defined a special regime of interchanges based on reciprocity. these political and economic practices favoured the maintenance of certain balance of forces, which is shown in the decrease of frontier struggle during the last decades of the colonial period.
El peronismo revisitado: Rupturas y continuidades de un debate que no pierde su centralidad
Brachetta,María Teresa;
Estudios de filosof?-a pr??ctica e historia de las ideas , 2008,
Abstract: this article explores the deep renovation in the ideological-cultural field that accompanies the return to democracy in the country, as well as the processes that bring about the formation of a new "cultural atmosphere". besides, through the conceptual and methodological news in the field, it analyses the production that aims at revisiting peronism at that time. in so doing, it attempts to tackle the continuity of the lines of the debate that started in previous decades, as well as a whole new line that at the beginning of the 80s began with the analyses of the "cultural battle" between politicians and intellectuals brought about by peronism after its first decline. the magnetism of peronism over the historiographical field in the 60s and 70s acquires a renewed vigour in the 80s, due to the political and ideological disputes and controversies in the interior of this political tradition in the period of the democratic transition. this new production is undoubtedly a fundamental chapter in the historiography of peronism, which continues in the following decades and inspires new readings. in this sense, this article attempts to join old and new ideas in the historiographical field, modulated by the changes in peronism as a political force since its electoral defeat against radicalism in 1983.
La elipsis en la interacción comunicativa y variación sociolingüística
Poblete,María Teresa;
Estudios filológicos , 2002, DOI: 10.4067/S0071-17132002003700007
Abstract: the purpose of this study is to identify and classify occurrences of ellipsis in question-answer and other rejoinder sequences in the interview, to establish its contribution to oral textual coherence. sociolinguistic variations derived from strata, age and sex of participants are also described. the corpus was taken from eighteen interviews to valdivian speakers, men and women, divided into three social strata and three age groups. the results show the significant presence of ellipsis in communicative interactions, its contribution to topic progression and to the coherence of the oral texts analyzed. the sociolinguistic variation shows to be derived from the speakers' decisions with respect to what they say, and their attitudes towards the interviewer's observations (questions and other utterances). the interviewees' attitude showed significant differences among strata, between men and women, and between the youngest generation and the two older ones.
