Entrevista a Ramón Grosfoguel
Angélica Montes Montoya,Hugo Busso
Polis : Revista de la Universidad Bolivariana , 2007,
Abstract: Grosfoguel habla acerca de la colonialidad del poder y de la posibilidad de una política radical más allá de las políticas de la identidad y de la articulación de un discurso crítico que supere el nacionalismo y el colonialismo. Propone superar los paradigmas de la economía política y los estudios culturales. Parte del criterio que colonialidad y modernidad son dos caras de la misma moneda y sintetiza la crítica a la epistemología eurocéntrica hegemónica, que asume un punto de vista universalista, neutral y objetivo. La solución a las desigualdades sociales globales requiere imaginar alternativas utópicas más allá del colonialismo y el nacionalismo, y de las formas de pensar binarias de los fundamentalismos eurocéntricos primermundistas y tercermundistas. Propone con Quijano la socialización del poder, y su aporte remite a un lenguaje crítico común descolonizador.
Caffeine's Vascular Mechanisms of Action
Darío Echeverri,Félix R. Montes,Mariana Cabrera,Angélica Galán,Angélica Prieto
International Journal of Vascular Medicine , 2010, DOI: 10.1155/2010/834060
Abstract: Caffeine is the most widely consumed stimulating substance in the world. It is found in coffee, tea, soft drinks, chocolate, and many medications. Caffeine is a xanthine with various effects and mechanisms of action in vascular tissue. In endothelial cells, it increases intracellular calcium stimulating the production of nitric oxide through the expression of the endothelial nitric oxide synthase enzyme. Nitric oxide is diffused to the vascular smooth muscle cell to produce vasodilation. In vascular smooth muscle cells its effect is predominantly a competitive inhibition of phosphodiesterase, producing an accumulation of cAMP and vasodilation. In addition, it blocks the adenosine receptors present in the vascular tissue to produce vasoconstriction. In this paper the main mechanisms of action of caffeine on the vascular tissue are described, in which it is shown that caffeine has some cardiovascular properties and effects which could be considered beneficial. 1. Introduction Coffee is one of the most frequently consumed beverages in the world. It represents a culture and an economy. It has been produced in Colombia since the nineteenth century and is the main export to more than 36 countries; in 2008 it represented close to 12.4% of the harvest of mild Arabica type coffee and 12.2% of worldwide coffee exports. There are approximately 590 coffee growing municipalities, 513,000 coffee growers, 640,000 direct employees, and more than a million indirect employees, which means approximately 2 million people dependent on coffee cultivation [1] Over 2,000 substances have been isolated from coffee. The major component of coffee is carbohydrates, which make up 38–42% of the toasted coffee bean, followed by lipids and amino acids with about 20 and 10%, respectively. Melanoidins make up 23% of the weight and are what give the beans their brown color. They also contain minerals, aliphatic and chlorogenic acids, trigonellines, and volatile aromas. Of the alkaloids, the most studied and recognized one is caffeine, which makes up 1.3 to 2.4% of the bean’s weight [2] followed by other purinic alkaloids such as theobromine and theophylline and pyridine such as trigonelline. Coffee consumption is generally associated with a large number of diseases and health alterations. However, the majority of epidemiological studies regarding this relationship have not yielded a clear conclusion, mainly due to the lack of concrete and continuous information regarding the frequency of consumption, the exact composition of the beverage, and factors associated with an unhealthy lifestyle

Abstract: Objetivo. El objetivo de este trabajo fue evaluar el funcionamiento neurocognitivo en un grupo de pacientes con trastorno de personalidad. Método. Diez pacientes con diagnóstico de trastorno de personalidad según el International Personality Disorder Examination (IPDE), sin patología del eje I del DSM-IV y que no recibían fármacos, fueron evaluados mediante la Escala de Inteligencia de Adultos de Wechsler (WAIS), la Escala de Memoria de Wechsler (WMS) y la Prueba de la figura compleja de Rey-Osterrieth. Resultados. Se encontró una serie de anormalidades, las que afectaban especialmente a la memorización de material complejo en la Prueba de Rey-Osterrieth y a la memorización de historias y tareas de control mental en la Escala de Memoria de Wechsler. Conclusión. Estos hallazgos pueden indicar déficits de la memoria visual compleja y de la memoria auditiva, los que pueden contribuir a las dificultades que presenta la psicoterapia de los pacientes con trastornos de personalidad. Objective.The objective of this study is to evaluate neurocognitive functioning in a group of patients with personality disorder. Method. Ten patients with a personality disorder according The International Personality Disorder Examination (IPDE), without axis I - DSM IV pathology and with no medication were evaluated through Wechsler Adult Intelligence Scale (WAIS), Wechsler Memory Scale (WMS) and Rey Osterrieth complex figure. Results. Abnormalities were found affecting especially memorization of complex material from Rey-Osterrieth figure and memorization of stories and control tasks from W.M.S. Conclusion. These findings may suggest disfunction of complex visual memory and hearing memory which may contribute to existing difficulties in psychotherapies of patients with a personality disorder.

Revista Chilena de Neuro-Psiquiatría , 2003,
Abstract: Introducción. Tanto la depresión como la impulsividad han sido asociadas a disfunciones del sistema serotoninérgico y ambas responden al tratamiento con inhibidores selectivos de la recaptura de serotonina. En este trabajo se estudia el efecto diferencial de fluoxetina sobre la impulsividad y los síntomas depresivos en pacientes con trastorno límite de personalidad. Sujetos y método. A 38 pacientes con trastorno límite de personalidad y sin patología del Eje I, se les administró fluoxetina en dosis flexibles por siete semanas. Fueron evaluados semanalmente mediante BPRS, GAF, escala de depresión de Hamilton y una escala de impulsividad. Se estudió la variación temporal del puntaje de estas escalas en dos grupos de pacientes: uno con elevada impulsividad y otro con baja impulsividad. Resultados. Hubo una mejoría de la sintomatología global y de los síntomas depresivos y la impulsividad en el grupo total de pacientes. En el grupo de sujetos más impulsivo hubo una mayor reducción de la impulsividad en las dos primeras semanas de tratamiento. En cambio, en los pacientes menos impulsivos hubo una mayor reducción de los síntomas depresivos a partir de la tercera semana de tratamiento. Ambas diferencias fueron estadísticamente significativas. Conclusiones. La fluoxetina tuvo un efecto diferencial sobre los síntomas depresivos y la impulsividad en los pacientes con trastorno límite de personalidad estudiados. Estos resultados concuerdan con los de otros autores y sugieren que los ISRS actúan por diferentes mecanismos neurobiológicos en ambos tipos de síntomas. Introduction. Depression and impulsivity has been associated to a dysfunction of serotonergic system and are treated with serotonin reuptake inhibitors (SSRI). In this work we study differential effects of fluoxetine on impulsivity and depressive symptoms in borderline personality disorders patients. Subjects and method. 38 borderline personality disorders patients without Axis I disorder were treated by seven weeks with flexible doses of fluoxetine. Patients were evaluated with BPRS, GAF, Hamilton Depression Rating Scale and an impulsivity scale. Temporal variations of symptomatology in high and low impulsive patients were compared. Results. Global symptomatology, depressive symptoms and impulsivity diminished. High impulsive patients present reduction in impulsivity in the first two weeks of treatment. Likewise, low impulsive patients had great reduction of depressive symptoms since the third week of treatment. Conclusions. Fluoxetine has a differential effect on impulsivity and depressive symptoms in b

Abstract: Los rabdomiomas cardiacos son tumores benignos dependientes de las fibras musculares miocárdicas, los cuales usualmente son múltiples, pero tienden a disminuir tanto en número como en tama o con el crecimiento, con una regresión espontánea en 90% de los casos. Hacen parte de los tumores cardiacos primarios, los cuales son poco frecuentes, con una incidencia que varía entre 0,0017% y 0,28%. El más frecuente de los tumores cardiacos primarios es el rabdomioma. Se describe asociación con esclerosis tuberosa hasta en 72% de los casos, razón por la cual ésta debe buscarse ante el hallazgo de rabdomioma cardiaco. Cardiac rhabdomyomas are benign tumors derived from cardiac muscle fibers. They are usually multiple, but tend to decrease both in number and size with growth, with spontaneous regression in 90% of cases. These lesions are part of the primary cardiac tumors, which are uncommon, and have a variable incidence between 0.0017 and 0.28%. The most common primary cardiac tumor is the rhabdomyoma. An association between rhabdomyoma and tuberous sclerosis has been described in up to 72% of cases. For this reason, a patient with cardiac rhabdomyoma should be investigated for tuberous sclerosis.
