Abstract: La educación es uno de los principales factores que promueven la movilidad social, siendo la educación secundaria clave, tanto para el desarrollo de procesos cognitivos superiores como para la definición del destino de los individuos, una vez que egresan del sistema escolar. La educación científica, mediante la generación de competencia científica, puede colaborar fuertemente en este desarrollo. A nivel tanto internacional como nacional se promueve el uso de la indagación científica como un enfoque pedagógico efectivo en el desarrollo de estas competencias, especialmente bajo contextos de alta vulnerabilidad. El presente trabajo expone algunos rasgos claves que debiera tener el profesor para implementar este enfoque. Finalmente se reflexiona acerca del rol de las universidades formadoras de profesores en el logro de este desafío. Education is one of the main factors that promote social mobility. Secondary education is important for the development of upper cognitive processes as for the destiny of the individuals, once they graduate of the school system. Scientific education, by means of the generation of scientific competence, can collaborate strongly in this development. At international and national level, the use of scientific inquiry is promoted as an effective pedagogical focus in the development of these competences, especially, at contexts of high vulnerability. The present work exposes some key features that teachers should have to implement this pedagogical focus. Finally, the role of science secondary teacher education is discussed.

"Es de suponerse que semejante delito haya sido cometido por mujeres...", o el miedo a las otras
María Teresa Garzón Martínez
Andamios , 2011,
Abstract: A través del análisis de un homicidio se habla de un momento específico de la historia de Bogotá, cuando el orden se orial colonial blanco entra en crisis por la aparición de nuevas clases sociales, específicamente el proletariado urbano y sus mujeres. Se muestra cómo el relato del homicidio es usado por la élite aristocrática blanca para representar el fantasma que le amenaza, generando miedo en torno a él, pero también se ilustra cómo el mismo puede generar procesos de resistencia al orden moderno/colonial.

Abstract:

Background: Labour induction is one of the most common medical procedures in obstetrics. The aim is to end the pregnancy when continuity is a risk to mother or fetus. Its main side effect is the increase in the cesarean rate, compared to spontaneous onset deliveries. On the other hand, mortality and morbidity in cesareans are higher. The most common pharmacological drugs used for induction are prostaglandins: dinoprostone and misoprostol. The “gold standard” for labour induction is vaginal misoprostol. The oral route is also effective and also has several benefits like faster onset and easear administration. In recent years several publications state that the administration of misoprostol oral solution, given in doses gradually, is associated with a lower cesarean and hyperstimulation rate than the cases where vaginal misoprostol has been used in pregnant women with unripe cervix. Furthermore, being its half life shorter, it may be very useful in case of uterine hyperstimulation and, probably, a high percentage of women prefer this oral administration to the vaginal one. The objective of this study is to compare the efficacy, safety and side effects on mother and fetus on use of oral versus vaginal administration for induction of labour for prolonged gestation (41 weeks) and premature rupture of membranes, both with live fetus. Methods/Design: Design: double blind controlled trial. Study population: Pregnant women whose labour will be induced due to premature rupture of membranes or prolonged gestation. Inclusion Criteria: 1) Bishop Test equal to or less than 7; 2) Single pregnancy; 3) Pregnancy at term (37 - 42 weeks); 4) No history of uterine surgery; 5) Cephalic presentation; 6) Live fetus; 7) No prostaglandins contraindications. Discussion: Nowadays induction rates are very high, ranging from 25% to 30% approximately. In these cases caesarean rates are higher than when the delivery starts spontaneously. That is one of the main reasons why caesareans have increased, mainly in the cases of nuliparous women with immature cervix. If we can prove the hypothetical good results obtained through the use of dosed oral misoprotol, we will be able to reduce the number of induced deliveries by cesarean, and so improve the levels of security for the mother and the foetus, and, as a consequence, provide a higher quality of medical attention to the newborn and the mother.

Administración de medicamentos por vía oral: Interacciones medicamento - alimento Oral drug administration: drug-food interactions

Abstract: Introducción: la vía oral de administración de medicamentos es la vía más cómoda, segura y económica. Sin embargo, pueden existir interacciones con otros fármacos o con alimentos que alteren la eficacia y seguridad de los mismos. Objetivo: desarrollar un programa de información dirigido a enfermeros y enfermeras sobre la administración de medicamentos por vía oral. Método: se seleccionan los medicamentos más utilizados en el área de cardiología pediátrica, revisándose para cada principio activo la administración en relación con alimentos o productos medicinales y otros aspectos relacionados con la administración por vía oral. Resultados: se elabora una tabla informativa sobre un total de 28 principios activos. Discusión: Los farmacéuticos de hospital se han integrado recientemente en los equipos multidisciplinares y desde esta posición tienen la oportunidad de desarrollar diferentes programas de atención farmacéutica, educación sanitaria e información encaminadas a prevenir problemas relacionados con los medicamentos, aumentar su uso seguro y disminuir los riesgos asociados a cualquier tratamiento farmacológico. Las prescripciones médicas generalmente no indican el horario y la forma de administración de los medicamentos, dejando a enfermeros y enfermeras la responsabilidad de su organización. Por esto deben estar informados de cómo y cuándo se deben administrar los medicamentos, lo que permite garantizar su uso seguro y disminuir los riesgos asociados al tratamiento. Background: The easiest, safest and cheapest way to administrate drugs is by mouth (PO). Nevertheless, there may be interactions, either with other drugs or with food, which can modify efficacy and security of the drug itself. Objective: the development of a nursing information program about the administration of drugs PO. Method: we selected the most used drugs corresponding to the pediatric cardiology area, looking for the best administration possible with or without food or medicinal products, and any other aspect related to their administration PO. Results: we elaborate the following table with all the information collected. Discussion: hospital pharmacists have recently been integrated in the multidisciplinary team that take care of patients, and so now they have the opportunity of developing different pharmaceutical care programs, sanitary education and information focused on the prevention of medication errors, the secure use and the diminish of any risks associated to any pharmacological treatment. Medical prescriptions usually do not specify timetable of way of administration of d

Abstract: brain trauma injury [bti], is the most common cause of brain injury which consequences, in a cognitive level, leads to attention disorders. the aim of this study is to evaluate the effect of a bti intervention program in the attention of patients who have a moderated bti. this program was applied to 3 men with an average of 9 years of education, with a media of 31, 6 years old, a glasgow result between 9 to 12 points, and no neurological nor psychiatric antecedents. also, the brief neuropsychological test battery [neuropsi], was applied as a sift, in which, the patients obtained a media of 100, finding errors in the attention, memory and motor skills tasks. the instruments used to determine the pre and post evaluation in the attention function were: the wisconsin card sorting test [wcst], the trail making test a and b [tmta-tmtb], the stroop task and the letter cancellation test. this research was quasi-experimental with a design of only one group; the efficacy of the intervention was evaluated through the difference between the pre and post media, once the program was applied. after the intervention, there were found changes statistically significant in the wcst in just one patient. however, all patients improved their reaction time and carried out cognitive tools such as planning, categorization and classifying

Abstract: The techniques employed in the manufacture of Iberian stone sculptures have received very little attention by the specialists. Nevertheless, this kind of research has provided important results in other Mediterranean areas, offering key insights not only about techniques, workshops and styles, but also about the social role of sculptors and those who support them. Through the study of a particular example, the lion-griffin confronting a snake from the sculptural group of Porcuna, we offer a general view about the way in which the sculpture was made. We have also recognized for the first time the presence of what can be interpreted as a sculptor’s mark, and we discuss the purpose of these kind of signs. El estudio de las técnicas empleadas en la manufactura de las esculturas ibéricas ha recibido escasa atención por parte de los especialistas. Sin embargo, estas investigaciones han ofrecido importantes resultados en otras áreas del Mediterráneo, proporcionando conocimientos clave no sólo sobre las técnicas, talleres y estilos, sino también sobre el papel social de los escultores y de aquellos que los sostienen. Mediante el estudio de un ejemplo concreto, el grifo-león enfrentándose a la serpiente del conjunto de Porcuna, se ofrece una visión general del proceso de trabajo de la escultura. Se ha reconocido por primera vez la presencia de lo que puede ser interpretado como una marca de escultor, y se discute la función de este tipo de signos.

Abstract: Con el objetivo de obtener una IgG anti-Cryptococcus neoformans, se llevaron a cabo simultáneamente 2 esquemas de inmunización en conejos con una cepa autóctona. Para ambos se emplearon células enteras formalinizadas que se diferenciaban entre sí en cuanto a dosis y vías de inmunización. Los sueros obtenidos fueron titulados y se seleccionó el de mayor título (1: 1 024 por el método de aglutinación en lámina) el cual fue purificado mediante precipitación salina y cromatografía de intercambio iónico, con la obtención de una IgG de pureza y actividad biológica altas.
