El movimiento indígena nacional único autor capaz de destrabar el conflicto?
Maya Lorena Pérez Ruíz
Revista mexicana de ciencias políticas y sociales , 2003,
Abstract: Este artículo trata sobre la situación de los derechos indígenas en el conflicto entre el EZLN y el gobierno federal mexicano. Se busca demostrar cómo el contenido jurídico de las reformas constitucionales empleadas, en diversos momentos, para impulsar u obstaculizar el diálogo y la negociación con los zapatistas a lo largo del conflicto ha quedado subordinado a una disputa de orden político y militar. Asimismo, y en el contexto posterior a los ataques terroristas del 11 de septiembre del 2001 en Estados Unidos, se ana izan las opciones del movimiento indígena nacional mexicano para conseguir sus derechos y contribuir, al mismo tiempo, al acercamiento entre el EZLN y el gobierno federal.
Algunas consideraciones sobre la hepatitis G
Vladimir Ruíz álvarez,Nora Clara Benítez Pérez
Revista Cubana de Medicina General Integral , 1999,
Abstract: La búsqueda de nuevos agentes capaces de producir inflamación hepática ha avanzado notablemente en los últimos a os. Recientenmente se reportó el aislamiento de dos nuevos virus mediante las técnicas de Biología Molecular, los cuales han resultado ser aislados idénticos de un mismo virus, cuyas características estructurales permiten incluirlo dentro de la familia Flavivirus. Existe discrepancia en los criterios sobre si este agente es capaz o no de causar hepatitis. Se plantea como principal vía de transmisión la parenteral, aunque no se descarta la propagación sexual o tal vez de paciente a paciente. Dada la poca capacidad del virus para inducir una respuesta inmune no ha sido posible hasta ahora obtener un ensayo serológico suficientemente seguro, y hasta tanto eso no ocurra serán difíciles los estudios epidemiológicos a gran escala The search of new agents capable of producing hepatic inflammation has advanced significantly during the last years. The isolation of 2 new viruses by molecular biology techniques has been reported recently. These viruses have proved to be identical isolates of the same virus, whose structural characteristics allow us to include it in the family Flavivirus. Whether this agent may cause hepatitis or not is under discussion. The parenteral route of transmission is considered as the main one, but sexual or even patient to patient spreading are not discarded. Due to the low capacity of the virus to induce an inmune responce, it has not been possible up to now to obtain a sufficiently safe serological assay, which makes difficult to conduct epidemiological studies at a large scale.

Abstract: Se realizó un estudio descriptivo retrospectivo que estuvo relacionado con la aplicación de la electroacupuntura en pacientes sometidas a legrados diagnóstico, con el objetivo de evaluar su efectividad. Se aplicó analgesia mediante la electroacupuntura a 201 pacientes que presentaron riesgos de contraindicaciones a la anestesia general y algunas que se decidieron a participar en el estudio de forma voluntaria. Se analizaron las variables: edad, riesgo anestésico, complicaciones transoperatorias, valoración del dolor, tipo de procedimiento realizado y evaluación del tratamiento. Se registró que el 63,1 % de los casos tenían entre 41-60 a os de edad, el 73,6 % de los pacientes presentaron riesgo anestésico y hubo una efectividad de la analgesia mediante la electroacupuntura para el 96,1 %. No refirieron dolor durante el transoperatorio el 85 % de los pacientes y solo el 9,9 % presentó complicaciones, predominando la hipertensión arterial. El 75,6 % refirió que el método de analgesia mediante la electroacupuntura fue una alternativa muy buena. A descriptive retrospective study related to the application of electroacupuncture in female patients undergoing diagnostic curettages was conducted in order to evaluate its efectiveness. Electroacupuncture analgesia was administered to 201 patients that presented risks of contraindications to general anesthesia and to some of them that decided to participate in the study as volunteers. The following variables were analyzed: age, anaesthetic risk, transoperative complications, assessment of pain, type of procedure carried out and treatment evaluation. It was observed that 63.1 % of the cases were between 41 and 60 years old, and that 73.6 % of the patients presented anesthesic risk. Electroacupuncture analgesia showed an effectivity of 96.1 %. 85 % of the patients did not refer pain in the transoperative, and only 9.9 % had complications, with predominance of arterial hypertension. 75.6 % considered electroacupuncture analgesia as a good alternative.

Rocío González López, M. Muinelo Lorenzo, J. Pérez Grobas, L. Muí?os Ruano, L. Ramírez Ruíz, A. Mohammed Salem, M. Rodríguez González, J. A. Costa Buján
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.37055
Abstract:

We present the case of an elderly patient, who had orthopaedic surgery and suffered in the early post-operative period an idiopathic gastric partial necrosis. We reviewed the literature and it is an extraordinarily infrequent entity. Partial resections have already been described in case of limited necrosis, as reported in our case. Prompt diagnosis of idiopathic gastric necrosis and aggressive treatment are mandatory. Further awareness of this strange entity and its risk factors can lead to a quicker diagnosis and higher possibilities of survival for the patient.

Ingenier?-a Energ??tica , 2013,
Abstract: in this paper the calculation of the transformation losses is discussed. the proposed method takes the variability and asymmetry of the load, as well as the presence of problems of energy quality like the unbalance and the voltages variations. the methodology applies to a primary distribution substation considering a probabilistic load curve to depart of measurements taken during a year. first the data got from intervening load measurement at the totalizing switch of the substation to construct eleven load profiles that they contribute to losses with determined probability. they get the more probable losses from the substation in 24 hours. the study case is arimao's substation in cumanayagua city. the method can be generalized to three-phase transformers installed at the industry where it be wanted to know its energetic behavior.

Revista Cubana de Medicina General Integral , 2000,
Abstract: drug surveillance is a procedure that depends greatly on the doctor with the objective of determining the possible causes of the poor notification of the adverse reactions of drugs (ard) in our environment. an anonymous survey was done among 145 medical professionals from 17 different specialities. 68 worked at the primary care level (pcl) and 77 at the secondary care level (scl). at the primary care level 40 % were specialists and 68 % residents, whereas at the secondary level 100 % were specialists. significant differences were observed between the pcl and the scl in most of the answeres given to the questions. the results allowed to conclude that doctors have experience and know about the adverse reactions of drugs but that the divulgation and the mechanism of modification should be improved in order to encourage doctors to report them.
Cambios en la composición lipídica de microsomas hepáticos de rata inducidos por la dieta
Ruíz Gutiérrez, V.,Pérez Espinosa, A.,García Muriana, F. J.
Grasas y Aceites , 1994,
Abstract: The effect on the hepatic microsomes from rats fed with either virgin olive oil (10%) or fish oil (10%), with or without added cholesterol (1%), has been studied. The fatty acid composition, desaturase activities and microviscosity (membrane fluidity) using male Wistar rats after weaning were determined. The results show that the fatty acid composition and other properties of the hepatic microsomes change with the diet. After cholesterol feeding, an increase in membrane microviscosity and a decrease in the activity of Δ6 desaturase were observed. Se realiza un estudio comparativo para determinar el efecto sobre los microsomas del hígado de ratas tras ser alimentadas con aceites de oliva virgen (10%) o pescado (10%), suplementados o no con colesterol (1%). Se emplearon ratas machos Wistar recién destetadas, y la composición en ácidos grasos, desaturasas y microviscosidad (fluidez de membrana) fueron determinados. Por el conjunto de resultados obtenidos en este trabajo podemos deducir que la composición y propiedades de las membranas microsomales hepáticas varían dependiendo de la alimentación. Destaca el incremento de la rigidez y el descenso significativo de la actividad desaturasa Δ6 de los microsomas hepáticos de los animales alimentados con las dietas ricas en colesterol.
