La necrosis, un mecanismo regulado de muerte celular
Ramírez Agudelo,María Elena; Rojas López,Mauricio;
Iatreia , 2010,
Abstract: three types of cellular death have been defined by morphological and biochemical criteria: apoptosis, necrosis and autophagy. apoptosis is a regulated cell death, mainly mediated by caspases; autophagy induces degradation of intracellular damaged organelles through the formation of vesicles that fuse with hydrolytic vacuoles. necrosis has been traditionally defined by the rupture the cytoplasmic membrane with subsequent release of intracellular material, triggering localized inflammatory intrinsic cellular activities and the events preceding cellular collapse are critical to determine the type of tissue damage. the fact that all three types of cellular death can coexist in any organ and tissue with different availabilities of atp, suggests that necrosis can be conceived as an active event and that to some extent it may be regulated. alterations in the structure of proteins and in the activity of different proteases, lipases and nucleases, indicate that each cell may have its own arsenal to trigger the events leading to necrosis. in this article we review some of the evidences on cellular regulation during necrosis.
Necrosis, a regulated mechanism of cell death La necrosis, un mecanismo regulado de muerte celular

Abstract: Three types of cellular death have been defined by morphological and biochemical criteria: apoptosis, necrosis and autophagy. Apoptosis is a regulated cell death, mainly mediated by caspases; autophagy induces degradation of intracellular damaged organelles through the formation of vesicles that fuse with hydrolytic vacuoles. Necrosis has been traditionally defined by the rupture the cytoplasmic membrane with subsequent release of intracellular material, triggering localized inflammatory Intrinsic cellular activities and the events preceding cellular collapse are critical to determine the type of tissue damage. The fact that all three types of cellular death can coexist in any organ and tissue with different availabilities of ATP, suggests that necrosis can be conceived as an active event and that to some extent it may be regulated. Alterations in the structure of proteins and in the activity of different proteases, lipases and nucleases, indicate that each cell may have its own arsenal to trigger the events leading to necrosis. In this article we review some of the evidences on cellular regulation during necrosis. Con base en criterios morfológicos y bioquímicos se han definido tres clases de muerte celular: apoptosis, autofagia y necrosis. La primera es una muerte celular regulada, mediada principalmente por caspasas; en la autofagia ocurre formación de vesículas que se fusionan con vacuolas hidrolíticas para degradar organelas intracelulares alteradas. En cuanto a la necrosis, se la ha definido tradicionalmente por la ruptura de la membrana citoplasmática con salida del material intracelular lo que desencadena una reacción
The Effect of Audio Visual Entrainment on Pre-Attentive Dysfunctional Processing to Stressful Events in Anxious Individuals  [PDF]
Guadalupe Villarreal Trevi?o, Ernesto Octavio López Ramírez, Guadalupe Elizabeth Morales Martínez, Claudia Castro Campos, María Elena Urdiales Ibarra
Open Journal of Medical Psychology (OJMP) , 2014, DOI: 10.4236/ojmp.2014.35038
Abstract: Experimental single case studies on automatic processing of emotion were carried on a sample of people with an anxiety disorder. Participants were required to take three Audio Visual Entrainment (AVE) sessions to test for anxiety reduction as proclaimed by some academic research. Explicit reports were measured as well as pre-attentive bias to stressing information by using affective priming studies before and after AVE intervention. Group analysis shows that indeed AVEs program applications do reduce anxiety producing significant changes over explicit reports on anxiety levels and automatic processing bias of emotion. However, case by case analysis of six anxious participants shows that even when all of the participants report emotional improvement after intervention, not all of them reduce or eliminate dysfunctional bias to stressing information. Rather, they show a variety of processing styles due to intervention and some of them show no change at all. Implications of this differential effect to clinical sets are discussed.

Abstract: therapeutic use of leeches (hyrudotherapy) has increased, and it has been shown that they can transmit bacteria associated with infections in 20% of patients. two species of leeches have been found in antioquia, colombia, apparently promising for such therapy. this study was done to identify bacteria in the surface, mouth and intestine of these species and to test the antibiotic sensitivity of the isolates. the studied species were haementeria sp., and oxytychus ornatus. specimens were obtained from their surface, mouth and intestine. blood agar, blood agar with ampicillin, and eosine-methylene blue agar were used as culture media. identification and sensitivity tests were carried out with the vitek (biomerieux?) automated method. a total of 26 isolates was obtained belonging to 12 species and nine genera. isolates were sensitive to the commonly used antibiotics. we suggest to do antibiotic prophylaxis in patients undergoing hyrudotherapy, and to implement standardized protocols to disinfect the animals before use and for the cleaning of the aquarium where they are kept.

Abstract: Se ha incrementado el uso terapéutico de las sanguijuelas y se ha demostrado que ellas pueden inocular bacterias causantes de infecciones en el 20% de los pacientes. El hallazgo en Antioquia de dos especies de sanguijuelas promisorias para hirudoterapia motivó este estudio para identificar las bacterias en la superficie, la probóscide y el intestino de estos anélidos y evaluar su sensibilidad a antibióticos. Las sanguijuelas estudiadas se identificaron como Haementeria sp., y Oxytychus ornatus. Muestras de la superficie, boca e intestino de ambos anélidos se inocularon en agar sangre, agar sangre con ampicilina y agar eosina azul de metileno. La identificación de las bacterias y su sensibilidad a antibióticos se evaluaron por el método automatizado Vitek (Biomerieux ). Se hicieron en total 26 aislamientos pertenecientes a 12 especies de nueve géneros. Enterobacter cloacae fue la especie más frecuente en ambos anélidos. Las bacterias fueron sensibles a los antibióticos comúnmente empleados en las infecciones causadas por este tipo de microorganismos. Se sugiere hacer profilaxis con antibióticos en los pacientes que reciban terapia con los anélidos investigados e implementar los protocolos estandarizados para el lavado de los animales antes de su uso y para el aseo de los acuarios en donde se los mantenga.

Abstract: Los pacientes de diálisis peritoneal son sometidos a la intervención enfermera ense anza individual para la obtención de conocimientos básicos, con el objetivo de efectuar el tratamiento en domicilio en condiciones de seguridad, que minimicen los riesgos que conlleva el proceso de diálisis peritoneal. La adecuación de los objetivos esperados a las características y/o capacidad del paciente/familia, consigue individualizar las actividades propias de la intervención ense anza, así como el nivel de conocimientos adquiridos. Los indicadores relacionados con el manejo del proceso, la infección, la hidratación y la dieta, sirven para conocer el nivel de conocimientos del paciente/familia, y así poder dar desde la unidad de diálisis peritoneal, apoyo y o seguimiento individualizado en el domicilio, según las necesidades del paciente. La evolución del manejo del régimen terapéutico, es un hecho que siempre preocupa a la enfermería de diálisis peritoneal; el cumplimiento tanto de las normas aprendidas durante el entrenamiento como de los procedimientos descritos, son de suma importancia para minimizar las complicaciones intrínsecas al proceso terapéutico que nos ocupa. La necesidad de establecer pautas para un reentrenamiento estructurado, hemos pretendido conocerla a través de los indicadores relacionados con los criterios de resultados que describimos a continuación: Conocimiento del manejo del régimen terapéutico (1813). Conducta de cumplimiento (1601). Control del riesgo (1902). Control de síntomas (1608). Los criterios de resultados esperados corresponden al diagnóstico estandarizado en nuestro medio de 0082 Manejo efectivo del régimen terapéutico y 00162 Disposición para el manejo efectivo del régimen terapéutico, que son las etiquetas diagnósticas por excelencia al alta tras el entrenamiento para efectuar la diálisis peritoneal en el domicilio. Patients undergoing peritoneal dialysis receive individual training provided by nursing staff in order to obtain basic knowledge so that they can carry out the treatment at home in conditions of safety that minimize the risks involved in the peritoneal dialysis process. Matching the desired goals to the characteristics and/or capacity of the patient/family individualizes the teaching activities and the level of knowledge acquired. Indicators related to the management of the process, infection, hydration and diet serve to determine the level of knowledge of the patient/family, and thus provide support from the peritoneal dialysis unit and/or individual monitoring at home, according to the patient's needs.

Abstract: Introducción: En el Sistema Sanitario Cubano, la salud pública y la salud individual se integran bajo los principios de universalidad, gratuidad, accesibilidad, continuidad, responsabilidad e integralidad de la atención que se brinda a individuos, familias y comunidades. Objetivo: Identificar el nivel de integración del Sistema Sanitario Cubano en distintos niveles de complejidad en la gestión y prestación de servicios. Métodos: Se tuvieron en cuenta los atributos propuestos por la Organización Panamericana de la Salud en el 2008, para conformar redes integradas de servicios de salud. Se aplicó una escala cualitativa ordinal, propuesta por la Organización Panamericana de la Salud. Se aplicó un instrumento a 58 unidades de análisis, de estas 15 en el grupo I, considerado expertos; 13 en el II (directivos de nivel municipal) y 30 en el III (directivos de nivel provincial). Se dise ó ad hoc un sistema de evaluación por índices para analizar los resultados. Resultados: Predominaron los atributos considerados integrados o parcialmente integrados. Los atributos de la integración, con mayores debilidades, fueron los relacionados con la integración del financiamiento presupuestado a las necesidades del sector y la integración de los procesos formativos del recurso humano en cantidad y calidad suficiente para las necesidades actuales, así como su comprometimiento con los servicios que prestan. El índice de integración por atributo y global, fueron similares para cada grupo, e indican una tendencia del Sistema de Salud Cubano hacia la integración. Conclusiones: El Sistema Sanitario Cubano tiende a la integración. Existen reservas de mejora en todos los atributos para la integración. Introduction: In the Cuban Health System, the public and individual health care integrated under the principles of universality, gratuitousness, accessibility, responsibility and completeness of the care offered to subjects, families and communities.

Abstract: background: among infectious diseases, those produced by parasites constitute a medical-social problem that not only affects to underdeveloped countries but to countries of high economic development. objective: to elevate the knowledge level on control measures in parasitism. method: an educational intervention study was carried out, which was applied to a group of mothers in the doctor′s office #4 at the ignacio agramonte polyclinic, of camagüey municipality from september to december 2009. the universe was constituted by 58 mothers and the sample remain conformed by 26 to those were applied a survey with different variables and knowledge aspects before and after the intervention. results: the majority of mothers had good socioeconomic level (69,2) and (65,3), oxyuriasis was the parasite most suffered in their children (61,5), before the strategy a reduced number of mothers recognized intestinal gases and hives like symptoms and signs, none of them identified the sibilant respiration. after the intervention the 100% of mothers recognized hands, fruits, and vegetables washing, to boil or chlorinate water, to avoid overflow of pits and drainages, besides protecting foods of dirtinesses. conclusions: intervention was satisfactory since it was achieved the biggest percent of mothers elevated their knowledge on the given topics.
Modelling Entrepreneurial Attitudes in Women Entrepreneurs with Bayesian Networks  [PDF]
Jorge López, Alicia Ramírez, Pilar Casado
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.33037
Abstract: The entrepreneurial attitude model is nowadays getting more attention as a framework to explain and describe new business creation. In short, the attitude model posits that the entrepreneurial behavior is a planed action conditioned by the potential entrepreneur’s attitudes which depends on desirability and feasibility beliefs. We have developed and compared three different Bayesian net models taking into account the principles of the Shapero’s entrepreneurial event model. We have also modeled feasibility using two different dimensions. Firstly, we considered opportunity feasibility dimension referring to the degree in which a business would be successful attending to the market opportunities or demands. Secondly, we included a dimension of resources feasibility referring to the feasibility of the business in terms of the availability of possible resources to make the company a reality. The first model contained both feasibility dimensions whereas the other two only contained one dimension. Our results show that the Bayesian model containing the two forms of feasibility is better to predict entrepreneurial intentions. Implications in the context of promoting entrepreneurial attitudes and behaviors amongst women are finally discussed.
