Native American ancestry significantly contributes to neuromyelitis optica susceptibility in the admixed Mexican population
Neuromyelitis Optica (NMO) is an autoimmune disease with a higher prevalence in non-European populations. Because the Mexican population resulted from the admixture between mainly Native American and European populations, we used genome-wide microarray, HLA high-resolution typing and AQP4 gene sequencing data to analyze genetic ancestry and to seek genetic variants conferring NMO susceptibility in admixed Mexican patients. A total of 164 Mexican NMO patients and 1,208 controls were included. On average, NMO patients had a higher proportion of Native American ancestry than controls (68.1% vs 58.6%; p = 5 × 10⁻⁶). GWAS identified a HLA region associated with NMO, led by rs9272219 (OR = 2.48, P = 8 × 10⁻¹⁰). Class II HLA alleles HLA-DQB1*03:01, -DRB1*08:02, -DRB1*16:02, -DRB1*14:06 and -DQB1*04:02 showed the most significant associations with NMO risk. Local ancestry estimates suggest that all the NMO-associated alleles within the HLA region are of Native American origin. No novel or missense variants in the AQP4 gene were found in Mexican patients with NMO or multiple sclerosis. To our knowledge, this is the first study supporting the notion that Native American ancestry significantly contributes to NMO susceptibility in an admixed population, and is consistent with differences in NMO epidemiology in Mexico and Latin America
Development of the Theory of Mind in children of Pre-elementary education
Recepción: 29 de julio de 2016 | Revisión: 6 de septiembre de 2016 | Aceptado: 19 septiembre de 2016Correspondencia: Natalia Hidalgo Ruzzante | Orcid ID: 0000-0002-9952-9478 | Email: [email protected]: Conceptos como empatía y Teoría de la Mente (ToM) han resurgido en educación gracias a la evidencia sobre su importancia en la vida de las personas. Objetivo: Estudiar la relación entre los diferentes componentes de la ToM y determinar la relación de variables sociodemográficas y educativas en el desarrollo de la ToM en alumnado de Educación Infantil. Método: 25 niños/as con edades comprendidas entre 5 y 6 años fueron evaluados. Se empleó una escala validada para evaluar ToM (EToM). Los ítems consisten en seis situaciones conflictivas como diversidad de creencias, deseos, emociones o conocimientos, presentados utilizando personajes y materiales lúdicos. Resultados: Los ítems de la escala, correspondientes a diferentes componentes de la ToM, están relacionados entre ellos con los adyacentes, no con los más distantes en el orden teórico establecido en la escala. No se han obtenido resultados significativos que indiquen la relación de edad, sexo, dificultades del lenguaje y tener hermanos/as con el desarrollo de la ToM. Conclusiones: EToM contiene ítems que pueden ser considerados indicadores del desarrollo evolutivo de la ToM en preescolares. Investigaciones con muestras más amplias podrán determinar la relación de la ToM con el sexo, la edad, el lenguaje y la convivencia con hermanos.Background: In recent years the concepts of empathy and Theory of Mind (ToM) have reemerged in the area of education, due to evidence of their value in people’s lives. Objective: To study what relation exists between the components of ToM, and determine the relationship of sociodemographic and educational variables in the development of ToM in children of Pre-elementary education. Method: 25 children between 5 and 6 years old were evaluated; a validated scale to assess ToM in children was used. The items consist of six conflict situations about differences in beliefs, desires and emotions among others, presented to the students using characters and play-based materials. Results: The items of the scale, corresponding to different components of ToM are related to each other but only with adjacent items, not with the more distant ones in the theoretical order established in the scale. No significant results were obtained indicating the relationship of between age, sex, language problems and having siblings in the development of ToM. Conclusion: The ToM Scale contains items that can be considered as indicators of an evolutionary development of ToM in children in pre-elementary Education. Studies with broader samples are needed to determine the relationship between ToM and sex, age, language and living with siblings.Universidad de Granada. Departamento de Psicología Social.

Radiative Transference Equation Algorithm as an ANSYS® User-Defined Function for Solar Technology Applications
Heat effects in photocatalytic reactor applications are discussed and a case study is analyzed where sunlight is used to activate a chemical reaction to degrade water pollutants. Heat is produced in the light-capturing process, and heat effects need to be better understood during the device design process. Radiative transfer equation (RTE) is the guiding equation used to calculate radiation proliferation in participating media, and it is used to describe the balance of radiative energy transport in the participating media including the interactions caused by different processes such as absorption, scattering, and emission, which also are subject to additional phenomena like weakening and magnification. This equation plays an important role in the design process since it may be included in the simulation process to represent the sunlight heat effects in the different photocatalytic reactor components. In this chapter, it is explained how to build a simplified algorithm to incorporate the RTE in a numerical calculation during the design of a photocatalytic reactor using the commercial software ANSYS®. In addition, simplifications are explained that enable the program to coordinate some coefficients such as absorption and dispersion so their effects are included within the numerical calculation. A user-defined function is presented in the end of the chapter as a usable algorithm in ANSYS® program with acceptable results for photocatalytic reactors

UGR Empática: programa de intervención para el desarrollo de la empatía en el alumnado de Ciencias de la Salud y Ciencias de la Educación
La capacidad empática es fundamental para garantizar el éxito profesional en las carreras de Ciencias de la Educación y Ciencias de la Salud. En tanto que se trata de una capacidad que puede entrenarse, este proyecto pretende desarrollar la empatía en el estudiantado de estas ramas del conocimiento. Para ello se diseñó una acción de innovación docente consistente en una serie de materiales didácticos en formato multimedia en los que se abordan diferentes aspectos de la empatía y que han sido empleados por los docentes de diferentes materias durante sus clases. Los materiales se han agrupado en 8 sesiones, cada una de ellas conteniendo dos actividades breves. Las actividades han sido presentaciones en videos en torno a 5 minutos y casos prácticos de elaboración propia de los componentes del equipo del PID. En cada sesión se ha incluido un ejercicio de aprendizaje por autoevaluación. La duración ha sido de 8 semanas, a razón de una sesión compuesta por las 2 actividades cada semana. Para determinar la eficacia de la acción innovadora se ha evaluado la capacidad de empatía en el estudiantado antes de iniciar el proyecto y tras la finalización del mismo, a través del Índice de Reactividad Interpersonal (IRI), una escala que mide la empatía de forma multidimensional. El IRI ofrece una medida compuesta de la empatía, incluyendo su dimensión cognitiva y afectiva. La empatía cognitiva se mide mediante el grado en el que la persona comprende el punto de vista de otra persona. El IRI tiene 2 escalas para medir empatía cognitiva: a) la Escala de Toma de Perspectiva, que evalúa cómo la persona intenta adoptar las perspectivas de otras personas y ver las cosas desde su punto de vista; y b) la Escala de fantasía, que mide la tendencia a identificarse con los personajes de las películas, novelas, obras teatrales y otras situaciones ficticias. La de mayor interés para este proyecto es la primera. En cuanto a la empatía afectiva o emocional, el IRI intenta captar la respuesta emocional de la persona cuando observa el estado afectivo de otras personas, y lo hace con otras 2 escalas: c) Escala de Preocupación Empática consta de ítems sobre los sentimientos de simpatía, compasión y preocupación por los demás; y d) la Escala de Angustia Personal, que valora si la persona experimenta ansiedad y malestar cuando observa que otros están atravesando por experiencias negativas. En nuestro estudio, el interés estaba en que aumentase la puntuación en la escala de preocupación empática, pero no en la de angustia personal. Los objetivos específicos fueron la mejora en las dimensiones de la capacidad empática más relevantes, considerando que la toma de perspectiva y la preocupación empática son las más relacionadas con el desempeño profesional del estudiantado al que iba dirigido el proyecto. En general, los resultados indican que el conjunto del alumnado que ha participado en el PID ha mejorado su capacidad empática. Por tanto, podemos considerar que los materiales creados son válidos para tal fin y pueden ser de aplicación práctica a la docencia.Empathic skills are fundamental to ensure professional success in the fields of Education and Health Sciences. As it is an ability that can be trained, this project aims to develop empathy in students of these branches of knowledge. To this end, a teaching innovation action was designed consisting of a series of teaching materials in multimedia format in which different aspects of empathy are addressed and which have been used by teachers of different subjects during their classes. The materials have been grouped into 8 sessions, each containing two short activities. The activities consisted of 5-minute video presentations and case studies developed by the IDP team. Each session included a self-assessment learning exercise. The duration was 8 weeks, with one session consisting of the 2 activities each week. To determine the effectiveness of the innovative action, the students' capacity for empathy was assessed before the start of the project and after its completion, using the Interpersonal Reactivity Index (IRI), a scale that measures empathy in a multidimensional way. The IRI provides a composite measure of empathy, including both cognitive and affective dimensions. Cognitive empathy is measured by the degree to which a person understands another person's point of view. The IRI has 2 scales to measure cognitive empathy: a) the Perspective Taking Scale, which assesses how the person tries to adopt other people's perspectives and see things from their point of view; and b) the Fantasy Scale, which measures the tendency to identify with characters in films, novels, plays and other fictional situations. Of most interest for this project is the first one. As for affective or emotional empathy, the IRI attempts to capture the person's emotional response when observing the affective state of other people, and does so with 2 other scales: c) the Empathic Concern Scale consists of items on feelings of sympathy, compassion and concern for others; and d) the Personal Distress Scale, which assesses whether the person experiences anxiety and discomfort when observing that others are going through negative experiences. In our study, the focus was on increasing scores on the empathic concern scale, but not on the personal distress scale. The specific objectives were to improve the most relevant dimensions of empathic ability, considering that perspective-taking and empathic concern are the most related to the professional performance of the target students. In general, the results indicate that the students who participated in the IDP as a whole have improved their empathic ability. Therefore, we can consider that the materials created are valid for this purpose and can be of practical application in teaching
Cervical determinants of anal HPV infection and high-grade anal lesions in women: a collaborative pooled analysis
Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer.International Agency for Research on Cance
Identification and Pathway Analysis of microRNAs with No Previous Involvement in Breast Cancer
microRNA expression signatures can differentiate normal and breast cancer tissues and can define specific clinico-pathological phenotypes in breast tumors. In order to further evaluate the microRNA expression profile in breast cancer, we analyzed the expression of 667 microRNAs in 29 tumors and 21 adjacent normal tissues using TaqMan Low-density arrays. 130 miRNAs showed significant differential expression (adjusted P value = 0.05, Fold Change = 2) in breast tumors compared to the normal adjacent tissue. Importantly, the role of 43 of these microRNAs has not been previously reported in breast cancer, including several evolutionary conserved microRNA*, showing similar expression rates to that of their corresponding leading strand. The expression of 14 microRNAs was replicated in an independent set of 55 tumors. Bioinformatic analysis of mRNA targets of the altered miRNAs, identified oncogenes like ERBB2, YY1, several MAP kinases, and known tumor-suppressors like FOXA1 and SMAD4. Pathway analysis identified that some biological process which are important in breast carcinogenesis are affected by the altered microRNA expression, including signaling through MAP kinases and TP53 pathways, as well as biological processes like cell death and communication, focal adhesion and ERBB2-ERBB3 signaling. Our data identified the altered expression of several microRNAs whose aberrant expression might have an important impact on cancer-related cellular pathways and whose role in breast cancer has not been previously described
