La participación del episcopado colombiano en las negociaciones con la insurgencia: orígenes y debates (1982-1990)
Cristancho,Andrea;
Civilizar Ciencias Sociales y Humanas , 2011,
Abstract: this paper analyses the most representative academic works about the participation of the colombian bishops' conference in negotiations with insurgent groups during the eighties, focusing on their perspective about their vision of peace. in that sense, this paper analyses how the colombian clergy adapted to the national reality their perspective of peace, identifying the main debates and the wide variety of answers, focusing on two main issues: the relevance of establishing a relationship between the need to address social issues with the overcoming of violence and the participation of bishops and priests in the talks with the insurgency. as a result of these discussions, the colombian catholic church gained greater unity in action on peace and conflict.
Identificación y análisis de secuencias de retrotransposones en Lycopersicon spp Identification and Analysis of Retrotransposon Sequences in Lycopersicon spp
Cristancho M.
Revista Colombiana de Biotecnología , 1999,
Abstract: Secuencias de retrotransposones del tipo Ty3/gypsy fueron identificadas en los genomas de tomate (Lycopersicon esculentum) y otras especies de Lycopersicon por medio de análisis de PCR. Las secuencias fueron altamente heterogéneas, como ha sido el caso para otras secuencias de retrotransposones identificadas en plantas. Un análisis de las secuencias amplificadas por PCR mostró que la filogenia de las secuencias Ty3/gypsy de tomate fue similar a la del género Lycopersicon. Este análisis también mostró que las secuencias pertenecen a secuencias de retrotransposones de lenta evolución y que parecen ser residentes desde tiempos ancestrales del genoma del tomate. Se obtuvo alguna evidencia que sugiere que los ele-mentos del tipo Ty3/gypsy en tomate podrían ser activos. Las líneas de evidencia en favor de la presencia de retrotransposones activos en tomate y su posible transmisión horizontal se analizan más profundamente. Retrotransposon Ty3/gypsy-like sequences were identified in the genomes of tomato (Lycopersicon esculentum) and several other Lycopersicon species by PCR analysis. The sequences were highly heterogeneous, as has been the case Analysis of sequences amplified by PCR showed that the phylogeny of the tomato Ty3/gypsy sequences was similar to that of the genus Lycopersicon. This analysis also showed that the sequences belong to slowly changing retrotransposon sequences and that they seem to be long time residents of the tomato genome. Some evidence was obtained that suggests that some Ty3/gypsy-like elements in tomato might be active. The lines of evidence in favour of the presence of active retrotransposons in tomato and their possible horizontal transmission are further discussed.
Una visión sociológica del derecho de familia en Colombia. Radicalismo-1945
Beltrán Cristancho,Mauricio;
Estudios Socio-Jurídicos , 2008,
Abstract: this paper affirms that the economic and political failure of the radical period provided opportunities for those who proposed regeneration as a means of defending authority. family law became an important tool in that process. during the period studied by this article, the equality clause remained in colombian constitutions without any practical affect for the majority of the people. discrimination was imposed through family law over those who had born outside of a catholic marriage and/or had not previously legitimized their union through a catholic ceremony. by the middle of the 20th century, the dramatic situation of the nation?s children led to efforts to change the social prejudices through legislation, that is, in the same way the prejudices had been imposed.
Intoxicación aguda por hierro
BUSTAMANTE CRISTANCHO,LUIS ALFONSO;
CES Medicina , 2011,
Abstract: poisoned patients represent a challenge at the diagnostic and therapeutic approach in the emergency department. iron poisoning is a relatively common medical condition in pregnant and pediatric patients due the easy acquisition of the mineral in supplements often prescribed in medical consultations and prenatal care programs. this poisoning has a high lethal potential, however to reach that state are required extremely high doses as 200 to 250 mg/kg of elemental iron, but recently it?s describe doses of 150 mg/kg and some authors reports of 75 mg/kg, but are beginning to show signs of toxicity with intakes of 15 - 20 mg/kg. in this paper, we made a review of acute iron poisoning, from basic metabolism, through existing mechanisms for the regulation of acute iron overload and taking concepts for understanding the pathophysiological processes. this review provides an overview of established diagnostic and therapeutic modalities, as well as input from some research for the possible identification of various antidotes different to deferoxamine. finally, it presents a diagnostic and therapeutic algorithm based on the review done.
Del propósito de la filosofía
Cristancho Altuzarra,José Gabriel;
Civilizar Ciencias Sociales y Humanas , 2010,
Abstract: it is vital to ask what to teach in philosophy and how, but to address this question, we must first determine with what purpose to do it, but above all, to know what isthe purpose of philosophy. perhaps by determining the essential basis it would be clearer to answer the question of teaching and learning, even more, all this will help to clarify the mission of the philosophy and the philosopher today. to resolve this ponder is a philosophical reflection on traditional academic practices. then, from some authors, it is made a dissertation on what is philosophy, to deduce in which aspects of the current academic practices is present or distant the philosophy. finally we propose some perspectives to extend the philosophy and teaching of philosophy.

La evaluación por portafolio: estrategia para modelar la responsabilidad personal. Un ejercicio de reflexión autocrítica sobre el papel de la mediación
Ana Maritza Cristancho García
Psicología desde el Caribe , 2003,
Abstract: Este artículo está enmarcado en el programa general de investigación de la Facultad de Ciencias Sociales, Humanas y Educativas de la Universidad Nacional Abierta y a Distancia, denominado Cultura, región y educación a distancia. La línea de investigación a la que se adscribe es evaluación de las habilidades para aprender a aprender en la Especialización en Pedagogía para el Desarrollo del Aprendizaje Autónomo. Se presentan los resultados de un ejercicio de reflexión autocrítica acerca del papel de la mediación en la comprensión y uso del portafolio como herramienta de autorregulación del aprendizaje. Partiendo de una breve presentación del concepto de portafolio como instrumento que permite reconstruir la biografía del aprendizaje y de una descripción inicial de la metodología de la investigación protagónica, se describe el desarrollo de un ejercicio de reflexión autocrítica sobre un incidente crítico vivido en un evento de coevaluación de portafolio. Se analizan los componentes de la actitud del mediador para luego plantear alternativas conceptuales y de acción frente a la evaluación por portafolio.
Cost-Effectiveness of Somatostatin Analogues for the Treatment of Acromegaly in Colombia  [PDF]
Rafael Alfonso-Cristancho, Santiago Herran Diazgranados, Kariluz Maestre Martinez, Oscar David Diaz-Sotelo
Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2012, DOI: 10.4236/ojemd.2012.24016
Abstract: Background: Somatostatin analogues have shown to be effective in controlling the levels of growth hormone and are recommended for the treatment of acromegaly. These treatments have high costs of acquisition and their use might be restricted in limited resource settings. Objective: To evaluate the cost-effectiveness of somatostatin analogues for acromegaly in Colombia. Setting/Subjects/Intervention: A decision model was developed using a hypothetical cohort of patients with Acromegaly. Patients were treated according to the clinical practice of the country. Response to treatment and transition probabilities were derived from published literature. Costs and resource utilization were extracted from public and private sources in Colombia. Main Outcome Measure(s): Cost-effectiveness ratio, measured in Colombian pesos in a 2 year time-horizon. Results: The total medical treatment costs for the octreotide group were (Colombian Pesos) COP$ 53,807,616, compared to the total costs for the lanreotide group of COP$ 83,126,567. In the octreotide arm 65.30% of the patients and in the lanreotide arm 59.50% of the patients were successfully controlled. The number of deaths was 295 (13.1%) and 302 (13.4%) for octreotide and lanreotide, respectively. Because the costs are lower and the effectiveness is higher for octreotide in comparison with lanreotide, octreotide is more cost-effective than lanreotide. Probabilistic sensitivity analyses were consistent showing octreotide as the most cost-effective option. Conclusions: Costs and effects of octreotide compare favorably to those of lanreotide in the treatment of acromegaly in Colombia. Sensitivity analysis showed that despite the uncertainty in cost-effectiveness ratio this result is robust.
RESPUESTA FISIOLóGICA Y CAPACIDAD ANTAGONISTA DE AISLAMIENTOS FILOSFéRICOS DE LEVADURAS OBTENIDOS EN CULTIVOS DE MORA (Rubus glaucus)
MEDINA,CLAUDIA M; CRISTANCHO,DIANA; URIBE,DANIEL;
Acta Biológica Colombiana , 2009,
Abstract: the phyllosphere is a complex ecosystem in which despite of having a great number of associated microorganisms, few studies have been designed to understand the ecophysiological characteristics of the microorganism?s inhabitant. yeasts, as an important element of this habitat, are exposed to a variable environment, affected by the host plant, age and leaf position, availability and nutrient quality, temperature, ph, radiation and water activity. all these factors produce an important selection pressure for the establishment of natural or introduced populations of yeast which may displace other phytopathogenic fungi. in this study 80 isolates of phyllospheric yeast were obtained from two blackberry crops (rubus glaucus). its potential niche was determined in terms of its capacity to growth at different conditions of temperature, ph, osmotic stress and uv radiation. the osmotic stress was the most restrictive evaluated condition for the obtained yeast. only six isolates presented a growth higher to 0.3 od units at 405 nm, when grown at 50% or 60% of glucose. this study identified the ecological niche of ten yeast phyllospheric isolates, selected for their capacity to growth at a wide range of conditions. four of these isolates lvf 34, lvf 43, lvf 44 and lvf 50 were selected for their antagonistic capacity against the phytopathogenic fungi botritys cinérea. its taxonomic determination allowed us to report for the first time isolates of candida kunwinensis and rhodotorula colostri with biocontrol capacity.

Mendieta I,Giovane; Cristancho M,Amparo E;
Revista Facultad Nacional de Salud Pública , 2009,
Abstract: objective: to identify the practice and social representations of the respiratory therapists, on the strategies of prevention of pneumonia associated to mechanical ventilation, of the unit intensive care of the kennedy hospital. methodology:qualitative inquiry, descriptive and explanatory character, the population, respiratorys therapist of the unit?s intensives cares, with a sample of captive type for convenience, conformed by seventeen respiratorys therapists who were applied a semistructured interview, applying the content analysis technique for their study. results: practices and social representations, are given around the patient, and therefore avoid prolonged mechanical ventilation, the suction procedure should be carried out by means of aseptic technique, on the other and, the strict execution of handling protocols of airway; as long as it should be norm for the whole personnel, hand washing. conclusions: it is observed the strategies of prevention are influenced by the theoretical references, however, these actors do not know the full prevention strategies, likewise the represented practices are related with the prevention through asepsis transmission of pathogens, and has an effect on the construction of social representations and therefore the knowledge of new practices will change the structure of representation.
