Análisis de la experiencia de formación de los Hermanos de La Salle en Istmina, Colombia durante los años 2002-2010
(2012) Restrepo Botero, Juan Carlos; Ortiz Escobar, Claudia Patricia; Ochoa Uribe, Ana Marcela
The Lasallian District of Medellin, Colom-bia requested Corporación Universitaria Lasallista to analyze the formation pro-cess received by postulants to De La Salle Brothers in Istmina, Colombia, from 2002 to 2010. Academic, religious, pedagogical, apostolic and personal formation experien-ces received there were analyzed in this case study –from a qualitative approach– by means of semi-structured interviews and focus groups. Personal and apostolic formations stand out among the results due to the characteristics of Istmina as a proper place for sensibilization and subjugation in proof of vocation. However, the reach of integral formation is questioned because academic formation presented meaningful deficiencies. In conclusion, even though formation experiences in vulnerable con-texts are appreciated –and contextualiza-tion of learning is deemed meaningful–, participants agree in the necessity of deve-loping strong competences to face educa-tional and apostolic practices.
Desarrollo Embrionario del Capaz Pimelodus grosskopfii (Steindachner, 1879)
(2012) Valbuena Villarreal, Rubén D.; Zapata Berruecos, Beatriz E.; David Ruales, Carlos Arturo; Cruz Casallas, Pablo Emilio
The knowledge of embryonic development in fish is important in native species with potential for fish farming, by virtue of which it makes possible to identify morphological and chronological events to establish management practices during incubation periods and larviculture. The capaz (Pimelodus grosskopfii) is a species with potential for commercial crop, due to their omnivorous eating habits and acceptance of its meat in the market. To study the embryonic development of the species, sexually mature adult specimens were induced to reproduce with carp pituitary extract (5.75 and 4.0 mgKg-1, females and males, respectively). The inseminated oocytes were incubated in an upward flow system 30 a 27 ± 1 ° C. The samples (n = 30) were collected at the same time of the extrusion, during fertilization, and every 15 minutes starting from 0 to 2 hours post fertilization (HPF) and every 30 minutes from 0 to 2 HPF, and every 30 minutes from 2 to 5 HPF; finally, between 5 HPF and hatching every 60 minutes. The fertilized oocytes had a spherical shape without adhesions and large perivitelline space. Embryonic development took 12 HPF. The differentiation in animal and vegetal pole occurred at 0.2 HPF, the first cleavage at 0.3 HPF, stratified and high blastodisc at 1.8 HPF, flattened blastodisc at 3.3 HPF, the epiboly <50% was observed at 4 HPF, the closure of the blastopore at 5.7 HPF, cranial-caudal differentiation and starting the neurolation at 7 HPF, the differentiation of the optic vesicles, otic and Kupffer's vesicle at 8.5 HPF, tail of the vitelum was released at 10 HPF, first movements were observed at 10.5 and finally hatching occurred at 12 HPF. When the larvae hatched, they showed a total length of 2987±67 µm, without depigmentation, rudimentary digestive system without oral and anal opening and the presence of chromatophores on the yolk sac.
Esquemas maladaptativos tempranos en estudiantes de grado décimo y undécimo con contrato pedagógico disciplinar
(2012) Londoño Ardila, Luis Felipe; Aguirre Laverde, Diana; Naranjo, Sayra Carolina; Echeverri Restrepo, Verónica
This study is within the field of educational psychology, from a cognitive approach, it is aimed to describe the early maladaptive schemes (EMS) being present in tenth and eleven grade students, who once had been under the disciplinary pedagogical contract at the educational institute José María Bernal (JOMABER) of Caldas, Antioquia-Colombia. This research is quantitative-type, with a descriptive method, and pretends to understand, describe, and evaluate the EMTs occurring in this students. This sample is composed by 52 students currently in tenth and eleventh grade, who are registered in pedagogical processes or disciplinary contracts, and whose ages range from 15 to 18. The questionnaire of Young Schemas, YSQ - L2, authorized by the University of San Buenaventura of Medellin (Colombia), was applied on these students. The results show that it is probable that the behaviors and problems of these teenagers may be related to early maladaptive schemes, such as vulnerability to harm and sickness, and rights/grandiosity, whose origin associates with the bringing-up styles being overprotective or permissive and indulgent. This results show failure in the management of authority, and in the establishment of well-defined standards and limits.
Pharmaceutical products in the environment: sources, effects and risks
(2012) Jiménez Cartagena, Claudio; Narvaez, John F.
Pharmaceuticals and personal care products have become an environmental problem in recent years. Their physicochemical properties and persistence in the environment have allowed the distribution of degradates and parent compounds in water, soil, air and food. The widespread use of pharmaceuticals and personal care products in hospitals, domestic residences, agricultural and industrial facilities has increased their discharge into the water bodies, and its toxicity has started to manifest in different biological components of ecosystems. The development of methods for sample treatment and instrumental analysis techniques has enabled the separation, identification and quantification of active ingredients and degradates with higher environmental impact, at concentrations of parts per billion or even parts per trillion. In addition, in vitro and in vivo assays have demonstrated their ecotoxicity in water, driving them to the classification of emerging organic pollutants, whose waste is indeterminate. Although their adverse effects are still unknown, they could have strong implications for global public health. This review presents the dynamics and the development of research over the past ten years about the presence of non-steroidal anti-inflammatory analgesics, antihypertensives, antibiotics and other drugs in water bodies. Similarly, it described the impact of pharmaceutical activity, hospital services and domestic effluents on water quality.

Jóvenes investigando, jóvenes creando

A partir de una una necesidad evidenciada dentro de una clínica de pequeños animales, específicamente en el área de la evaluación renal en caninos; los parámetros de referencia normales de creatinina sérica que utilizan los médicos veterinarios y laboratorios en el sur del Valle de Aburrá son tomados de la literatura disponible de estudios foráneos, y a partir de ellos el médico veterinario local determina el estado de normalidad o no de la función renal en los caninos. Se cuenta únicamente con un valor estándar de los niveles de creatinina (0.5-1.5 mg/dL) establecido por los laboratorios basados en la literatura, sin embargo, es necesario evaluar cómo el peso influye en los valores establecidos por el laboratorio con el fin básico de poder estandarizar esos valores de forma más precisa para el correcto manejo de los pacientes con enfermedad renal.

La sabiduría en Aristóteles: conocimiento de principios y causas en el científico que experimenta con animales
(2014) Garcés Giraldo, Luís Fernando; Giraldo Zuluaga, Conrado
Aristotelian wisdom is understood as the intellectual virtue that, as it is simultaneously science and intellect, acknowledges the principles and the causes of the things that must be useful for oneself. Therefore for Aristotle a wise person is the one who knows everything as much as possible, possessing the science of the universe in a maximum degree. Aristotle tells us about the way we must interpret prudence and wisdom, by saying that they are both different, but mutually complementary. This reflection, in short, is the one approached by this article, by going into detail about the theory of the Aristotelian virtues and the "supreme" virtue among them, which is wisdom (as it is regarded by Aristotle) and its influence on researchers that conduct experiments on animals, given the fact that those researchers must observe universal ethical principles to develop their research works.

Los probióticos son microorganismos vivos, no patógenos, que producen efectos favorables sobre el organismo animal, cuando son proporcionados en cantidades y tiempos adecuados. Estos colonizan el tracto gastrointestinal e inhiben el crecimiento de microorganismos patógenos. Esto permitió evaluar la conversión alimentaria y la ganancia de peso en cerdos suplementados con cepas nativas de probióticos Pediococcus pentaceous, mediante la comparación en la administración de estos en dos tratamientos: (1) Tratamiento Control (TC) y (2) Tratamiento Experimental (TE) con 2 % de probióticos sobre la dieta diaria, empleando 12 animales experimentales (6 TC y 6 TE) de la misma edad. Los datos se tomaron cada 15 días mediante el pesaje de los animales durante los 60 días que duró la investigación y se analizaron con ayuda del paquete estadístico Statgraphics Centurion. Los resultados obtenidos mostraron que no hubo diferencias significativas entre los dos tratamientos, en cuanto a ganancia de peso y conversión alimenticia.
