    Breast cancer is a group of multigenic diseases. It is the most common cancer diagnosed among women worldwide and is often treated with tamoxifen. Tamoxifen is catalysed by cytochrome P450 2D6 (CYP2D6), and inter-individual variations in the enzyme due to single nucleotide polymorphisms (SNPs) could alter enzyme activity. We evaluated SNPs in patients from Colombia in South America who were receiving tamoxifen treatment for breast cancer. Allelic diversity in the CYP2D6 gene was found in the studied population, with two patients displaying the poor-metaboliser phenotype. Molecular dynamics and trajectory analyses were performed for CYP2D6 from these two patients, comparing it with the common allelic form (CYP2D6*1). Although we found no significant structural change in the protein, its dynamics differ significantly from those of CYP2D6*1, the effect of such differential dynamics resulting in an inefficient enzyme with serious implications for tamoxifen-treated patients, increasing the risk of disease relapse and ineffective treatment

    Introduction: Sedentary work activities in urban transport drivers are associated with overweight and obesity, an increase in musculoskeletal discomfort related to work and a decrease in physical fitness. Objective: To determine physical fitness and musculoskeletal discomfort in urban transport drivers from Barranquilla, Colombia, based on their body mass index (BMI). Material and Methods: Cross-sectional study conducted in 231 urban transport drivers. Healthy physical fitness and presence of musculoskeletal symptoms were measured using the AFISAL-INEFC test battery and the Nordic Questionnaire developed by Kuorinka, respectively. Results: There were significant differences between drivers with normal BMI and overweight/obese drivers in abdominal strength and endurance (21.4±8.9 vs. 19.6±8.8 stooped, p=0.04), flexibility (36.1±7.3 cm vs. 33.6±7.1 cm, p=0.02), and aerobic capacity (1537.5±704.8 meters vs. 1249.1±346.6 meters, p=0.0001). Increased frequency of musculoskeletal discomfort was observed in subjects with BMI >25 kg/m2. Conclusions: Overweight and obesity are associated with poor physical fitness and the perception of musculoskeletal discomfort, which has negative implications for the personal and occupational well-being of these workers, generating a burden for companies and the Colombian health system.Introducción.

    Environments of deterritorialization and counter-hegemony: an existential look at the Pedagogy of meetings from the image-cinema

    No full text
    Se pretende abrir la mirada a una construcción pedagógica que subvierta el aparente orden escolar que conmina tanto a los sujetos como a los saberes a ejercicios de transmisión donde la decisión del aprendiz esta reglado de antemano por una naturaleza hegemónica que controla el trámite de las enseñanzas. Por tanto, proponemos una pedagogía de los encuentros que mediada por la imagen-cine oriente praxis creativas que apelen a los sentidos inciertos e intempestivos de una experiencia desbordada estética y políticamente para privilegiar procesos existenciales de creación y resistencia. Así, damos curso a una expresión pedagógica siempre abierta que no restrinja, sino que estimule y comunique el tránsito de las diferencias.It is intended to open the eye to a pedagogical construction that subverts the apparent school order that brings both, subjects and knowledge to transmission exercises where the learner's decision is regulated beforehand by a hegemonic nature that controls the teaching process. Therefore, we propose a pedagogy of meetings, in which mediated by the image-cinema orientates creative praxis that appeals to the uncertain and untimely senses of an aesthetically and politically overflowed experience to privilege existential processes of creation and resistance. Thus, we give way to an always-open pedagogical expression that does not restrict but stimulates and communicates the transit of differences

    Objetivo: evaluar la Teoría de la Mente (ToM) y el funcionamiento cognitivo como componente de la cognición social en las personas en proceso de reintegración de la Agencia Colombiana para la Reintegración (ACR) en el grupo territorial Cesar-Guajira. Método: diseño de comparación multicaso, con una muestra de 3 hombres y 2 mujeres, con edades entre 23 y 43 años. Instrumentos aplicados: Addenbrooke’s Cognitive Examination Revisado – ACE R; Test de la Mirada (TdlM) de Baron-Cohen para Adultos; Escala de Ansiedad Manifiesta – AMAS Forma A en adultos y; Escala de Trauma de Davidson (DTS). Resultados: se identificó que los sujetos presentaron déficit en ToM, ya que tuvieron dificultades para el reconocimiento de estados emocionales básicos y diferenciar estados emocionales complejos con distinta tonalidad afectiva. Conclusiones: se estableció que se requiere estudiar a profundidad el grado de relación entre alteraciones cognitivas, funcionamiento cognitivo, ToM y trauma para estimar gradualmente relaciones directas o nulas.Objective: to evaluate the Theory of the Mind (ToM) and cognitive functioning as a component of social cognition in people in the process of reintegration of the Colombian Agency for Reintegration (ACR) in the territorial group Cesar-Guajira. Method: multicase comparison design, with a sample of 3 men and 2 women, aged between 23 and 43 years. Applied instruments: Addenbrooke’s Cognitive Examination Revised - ACE R; Baron-Cohen Test of the Look (TdlM) for Adults; Manifest Anxiety Scale - AMAS Form A in adults and; Davidson Trauma Scale (DTS). Results: it was identified that the subjects presented deficit in ToM, since they had difficulties for the recognition of basic emotional states and to differentiate complex emotional states with different affective tonality. Conclusions: it was established that it is necessary to study in depth the degree of relationship between cognitive disorders, cognitive functioning, ToM and trauma to gradually estimate direct or null relationships

    Integrated analysis of microRNA regulation and its interaction with mechanisms of epigenetic regulation in the etiology of systemic lupus erythematosus

    No full text
    The aim of this study was to identity in silico the relationships among microRNAs (miRNAs) and genes encoding transcription factors, ubiquitylation, DNA methylation, and histone modifications in systemic lupus erythematosus (SLE). To identify miRNA dysregulation in SLE, we used miR2Disease and PhenomiR for information about miRNAs exhibiting differential regulation in disease and other biological processes, and HMDD for information about experimentally supported human miRNA–disease association data from genetics, epigenetics, circulating miRNAs, and miRNA–target interactions. This information was incorporated into the miRNA analysis. High-throughput sequencing revealed circulating miRNAs associated with kidney damage in patients with SLE. As the main finding of our in silico analysis of miRNAs differentially expressed in SLE and their interactions with disease-susceptibility genes, post-translational modifications, and transcription factors; we highlight 226 miRNAs associated with genes and processes. Moreover, we highlight that alterations of miRNAs such as hsa-miR-30a-5p, hsa-miR-16-5p, hsa-miR-142-5p, and hsa-miR-324-3p are most commonly associated with post-translational modifications. In addition, altered miRNAs that are most frequently associated with susceptibility-related genes are hsa-miR-16-5p, hsamiR- 374a-5p, hsa-miR-34a-5p, hsa-miR-31-5p, and hsa-miR-1-3p
