Tratamiento de adicciones en Colombia
Hernández,Delia Cristina;
Revista Colombiana de Psiquiatría , 2010,
Abstract: introduction: in the face of recent debates linked to the penalization of the personal dose and the intention of implementing a mandatory rehabilitation treatment for consumers it is important to analyze all legal, epidemiological, social and clinical contexts of the problem and the treatment options available in the country. objective: to review the epidemiological, social and comorbidity aspect of the addictive conducts and establish a relationship with the characteristics of the treatment centers existing in the country. method: a research using pubmed, ebsco, host and ovid sp databases, using keywords such as addiction, treatment, comorbidity, psychoactive substances (pas). the works, published in the last decade were prioritized using strict scientific methodology. prior publications were included since they were the first national epidemiological studies on pas. results: the pas consumption continues to expand in the country and is strongly associated to mental illness (personality disorders, bipolar i and ii disorder, anxiety disorders and psychosis). these can be identified and treated by specialized professionals. conclusion: the pas consumption (a public health issue) requires an integrated treatment that takes into consideration the particularities of each subject and its co morbidity. the available treatment centers are insufficient to satisfy the demand. a vast number of them do not have the minimum elements to guarantee an adequate treatment and to identify the dual pathology involved.
Larval feeding behavior of the truncatus group of Thrypticus (Diptera: Dolichopodidae) that breed in the aerenchyma of Pontederiaceae
Hernández,M. Cristina;
Revista de la Sociedad Entomol?3gica Argentina , 2007,
Abstract: larval feeding behavior of the truncatus group of thrypticus (diptera: dolichopodidae) that breed in pontederiaceae species are presented. the larvae of t. circularis bickel & hernández develop in globous petioles of eichhornia crassipes (martius) solms- laubach (pontederiaceae), digging a mine near the epidermis and forming several holes to the exterior. t. romus bickel & hernández develop in e. azurea (sw.) kunth petioles; the mine is curved and short compared with other thrypticus species. t. formosensis bickel & hernández develops in pontederia cordata l. (pontederiaceae), and digs the mine between the epidermis and the big central cell of the petioles. t. taragui bickel & hernández breeds in submersed stems of p. subovata (seub. in mart.) lowden, and forms a mine close to the epidermis with branches to the central vascular stele. the mines of t. yanayacu, t. chanophalus and t. azuricola could not be associated with the corresponding species. neither predators nor parasites were found associated with the group, but some cases of cannibalism were observed when two mines were confluent. the truncatus group species have a very specific feeding habit, live completely enclosed within host plant tissues, and feed on the sap obtained from holes chewed in the vascular bundles of the petioles, possibly using yeast as supplementary nourishment. extensive field collections and laboratory tests indicate that each species in the truncatus group is associated with a specific host plant in the pontederiaceae. such specialization suggests a long association between the members of this group and their respective host plants.
Tratamiento de adicciones en Colombia Treatment of Addiction in Colombia
Delia Cristina Hernández
Revista Colombiana de Psiquiatría , 2010,
Abstract: Introducción: Frente a la polémica sobre la penalización de la dosis personal y la pretensión inicial de forzar a los consumidores a tratarse, es importante precisar los contextos legal, epidemiológico, social y clínico de la problemática y los tratamientos disponibles en el país. Objetivo: Revisar los aspectos epidemiológicos, sociales y de comorbilidad de los trastornos adictivos y relacionarlos con las características de los centros de tratamiento existentes en el país. Método: Búsqueda en bases de datos Pubmed, EBSCO, Host y OVID SP, utilizando como palabras clave: adicción, tratamiento, comorbilidad y sustancias psicoactivas (SPA). Se priorizaron los trabajos publicados en la última década con estricta metodología científica. Se incluyeron publicaciones anteriores por tratarse de los primeros estudios epidemiológicos nacionales sobre consumo de SPA. Resultado: El consumo de SPA continúa en aumento. Está frecuentemente asociado con enfermedad mental (trastorno de personalidad, trastorno bipolar I y II, trastornos de ansiedad y psicosis), por lo que se requiere manejo profesional especializado. Conclusión: El consumo de SPA (un problema de salud pública), necesita un tratamiento integrado que considere las individualidades del sujeto y su comorbilidad. Los centros de tratamiento disponibles en el país son insuficientes para satisfacer la demanda. Un gran número de ellos carecen de los elementos mínimos para garantizar una atención adecuada, así como la identificación de patología dual.

Abstract: Larval feeding behavior of the truncatus group of Thrypticus (Diptera: Dolichopodidae) that breed in Pontederiaceae species are presented. The larvae of T. circularis Bickel & Hernández develop in globous petioles of Eichhornia crassipes (Martius) Solms- Laubach (Pontederiaceae), digging a mine near the epidermis and forming several holes to the exterior. T. romus Bickel & Hernández develop in E. azurea (Sw.) Kunth petioles; the mine is curved and short compared with other Thrypticus species. T. formosensis Bickel & Hernández develops in Pontederia cordata L. (Pontederiaceae), and digs the mine between the epidermis and the big central cell of the petioles. T. taragui Bickel & Hernández breeds in submersed stems of P. subovata (Seub. in Mart.) Lowden, and forms a mine close to the epidermis with branches to the central vascular stele. The mines of T. yanayacu, T. chanophalus and T. azuricola could not be associated with the corresponding species. Neither predators nor parasites were found associated with the group, but some cases of cannibalism were observed when two mines were confluent. The truncatus group species have a very specific feeding habit, live completely enclosed within host plant tissues, and feed on the sap obtained from holes chewed in the vascular bundles of the petioles, possibly using yeast as supplementary nourishment. Extensive field collections and laboratory tests indicate that each species in the truncatus group is associated with a specific host plant in the Pontederiaceae. Such specialization suggests a long association between the members of this group and their respective host plants. Se da a conocer el comportamiento alimentario de las larvas de algunas especies del grupo truncatus de Thrypticus (Diptera: Dolichopodidae), que se desarrollan en plantas hospedadoras de Pontederiaceae. Los estadios inmaduros de T. circularis Bickel & Hernández se crían en los pecíolos globosos de Eichhornia crassipes (Martius) Solms-Laubach (Pontederiaceae), minando cerca de la epidermis y abriendo varios orificios al exterior. La larva de T. romus Bickel & Hernández crece en E. azurea (Sw.) Kunth, formando una mina curva, corta en comparación con las otras especies. La larva de T. formosensis Bickel & Hernández se desarrolla en Pontederia cordata L. (Pontederiaceae), excavando la mina entre la epidermis y la gran celda central de los pecíolos. Por último, la larva de T. taragui Bickel & Hernández se cría en tallos sumergidos de P. subovata (Seub. in Mart.) Lowden, formando una mina subepidérmica con ramificaciones hacia la estela central del t
ópera o “limbo”. Escenografía y música para la creación de un mundo entre realidad y fantasía en la Rusia finisecular
Cristina Aguilar Hernández
Cuadernos de Música, Artes Visuales y Artes Escénicas , 2012,
Abstract: El presente artículo propone una inmersión en el espectáculo operístico ruso de finales de siglo, con especial atención a los teatros privados de ópera –en particular, la ópera privada de Ma- montov–, el lugar donde la clase intelectual tuvo por primera vez una forma de expresión libre al margen de los aparatos del poder. La filosofía estética de estos grupos se expresa mediante la “unión de las artes”, que se alcanza mediante la interacción de escenografía y música, núcleos entorno a los que se desarrollará el análisis de esta exposición. Una simbiosis que dará lugar a obras en las que se diluyen los límites de la realidad tangible para explorar mundos de evasión desconocidos para el espectador ruso y el europeo.

El Cotidiano , 2011,
Abstract: Desentra ar las implicaciones ético-políticas y pedagógicas de la función social asignada a un sector de trabajadores que son definidos desde su condición de estar al servicio de un Estado que es manipulado por la burguesía neoliberal trasnacional, y además depositarios del discurso político hecho propuesta pedagógica desde el cual habrán de cumplir el compromiso social de poner a la educación al servicio del pueblo, es uno de los retos que habrán de ser atendidos desde el Movimiento Pedagógico Nacional Popular. La intención de este ensayo es recuperar el proceso e implicaciones de lo que llamamos debate pedagógico, entendido como la participación del magisterio en los procesos de dise o de la política educativa y su desarrollo pedagógico en la escuela pública, situación que habla de la particular manera de apropiación de todo ese discurso educativo en cuanto materia de trabajo y su recuperación instrumental o su elaboración o resignificación desde los referentes culturales de la comunidad en la que está inserta la escuela.
Relevance of Family in Academic Success on Children  [PDF]
Patricia Martínez Lanz, Ana Cristina Losada Fernández, Fabiola Pecchioni Fernández, Martha Patricia Hernández Valdez
Health (Health) , 2017, DOI: 10.4236/health.2017.92019
Abstract: The purpose of this study was to analyze the relationship between academic success and functional and dysfunctional families. A non-experimental, cross-sectional, descriptive correlational design was used. A convenience sample of 200 children between 6 and 13 years old, primary and junior high school students was conducted (32.3% were female and 67.7% were male). To assess the relationship, a study case of 21 reagents was designed to empty the obtained information from medical review records from a psychopedagogic clinic. Academic success was measured as from the revision of informal tests and standardized tests. Results showed that the population levels of academic success were average. However, a significant relationship between the age of the parents and the level of academic success was found, indicating that these variables are associated with this problem. Besides that, it was found that there is a tendency in children with cognitive, emotional and sensory problems reflected in low academic success. The findings provide information that could be considered for the development of programs of psychopedagogic intervention to treat children with learning disabilities and low academic success.
Iron Overload in Diabetic Retinopathy: A Cause or a Consequence of Impaired Mechanisms?
Andreea Ciudin,Cristina Hernández,Rafael Simó
Experimental Diabetes Research , 2010, DOI: 10.1155/2010/714108
Abstract: Iron is an essential ion for life, playing a central role in many metabolic processes. The most important property of free iron is its capacity to be reversibly oxidized and reduced, but at same time this make it highly pro-oxidant molecule. In this regard, iron is able to generate powerful reactive oxygen species (ROS). For this reason, careful control on iron availability is central to the maintenance of normal cell function in the retina. In the diabetic eye there is an impairment of iron homeostasis, thus leading to iron overload. The mechanisms involved in this process include: (1) Destruction of heme molecules induced by hyperglycemia (2) Intraretinal and vitreal hemorrhages (3) Overexpression of the renin-angiotensin system. The main consequences of iron overload are the following: (1) Retinal neurodegeneration due to the increase of oxidative stress (2) Increase of AGE-RAGE binding (3) Defective phagocytosis of retinal pigment epithelium, which generates the accumulation of autoantigens and the synthesis of proinflammatory cytokines. Further studies addressed to explore not only the role of iron in the pathogenesis of diabetic retinopathy, but also to design novel therapeutic strategies based on the regulation of iron homeostasis are needed.
Entre Babilonia y París: el azar domesticado de Borges a Cortázar
Hernández Escobar, María Cristina;
Latinoamérica. Revista de estudios Latinoamericanos , 2010,
Abstract: on borges' fiction, whole life is organized according the rules of a collective passion: risk. furthermore the topics of chance and fate, the author brings in a third one: chaos in society or, more exactly, the construction of a new cosmos recombining the ruins of the precedent one. draw after draw, a totalitary system where liberum arbitrium is banned has being constructed. lottery weaves an unending, closed net. on cortázar's story, chance and liberum arbitrium crisscross each other tracing axes that will be the privileged paths for a game -this time an individual and non-profit game-, that pursuives the disruption of "the stupid chains of daily life causality". all begins into the paris metro system.
