La influencia del peso y la talla en la erupción de la dentición temporal
2017
Objetivos: investigar la cronología y la secuencia de erupción de la dentición temporal y su relación con el peso y la talla en un grupo de niños y niñas de entre 0 y 3 años tanto al nacer como en la exploración. Analizar si existen diferencias significativas en la edad de erupción entre dientes contra laterales y entre dientes antagonistas para ambos sexos. Metodología: La muestra recogida fue constituida por 489 niños de raza caucásica, de los cuales 236 eran niños (48.3%) y 253 eran niñas (51.7%), asignados a dos centros de salud, seleccionados al azar. Todos los niños eran nacidos a término y tenían una edad comprendida entre 3 meses y 36 meses de edad. Ninguno de ellos presentaba alter…
Rac1-Regulated Endothelial Radiation Response Stimulates Extravasation and Metastasis That Can Be Blocked by HMG-CoA Reductase Inhibitors
2011
Radiotherapy (RT) plays a key role in cancer treatment. Although the benefit of ionizing radiation (IR) is well established, some findings raise the possibility that irradiation of the primary tumor not only triggers a killing response but also increases the metastatic potential of surviving tumor cells. Here we addressed the question of whether irradiation of normal cells outside of the primary tumor augments metastasis by stimulating the extravasation of circulating tumor cells. We show that IR exposure of human endothelial cells (EC), tumor cells (TC) or both increases TC-EC adhesion in vitro. IR-stimulated TC-EC adhesion was blocked by the HMG-CoA reductase inhibitor lovastatin. Glycyrr…
Managing for Results in Primary Education: Results of a Randomized Trial in Madagascar
2012
International audience; Using information from a randomized experiment carried out over the course of two school years in Madagascar, this paper evaluates the impact of specific actions designed to streamline and tighten the work processes of public primary school directors. The results show that interventions at the school level, reinforced by interventions at the district and subdistrict levels, succeeded overall in changing school heads' behavior toward better management. However, the average impact hides important heterogeneity. The impact of the intervention was significantly larger among school heads who had a nonpermanent contract and among school principals who were responsible for …
Oxidative and nitrosative stress in the metastatic microenvironment.
2010
Metastases that are resistant to conventional therapies are the main cause of most cancer-related deaths in humans. Tumor cell heterogeneity, which associates with genomic and phenotypic instability, represents a major problem for cancer therapy. Additional factors, such as the attack of immune cells or organ-specific microenvironments, also influence metastatic cell behavior and the response to therapy. Interaction of cancer and endothelial cells in capillary beds, involving mechanical contact and transient adhesion, is a critical step in the initiation of metastasis. This interaction initiates a cascade of activation pathways that involves cytokines, growth factors, bioactive lipids and r…

Clinical assessment and comparison of ACL reconstruction using synthetic graft (Neoligaments versus FiberTape).
2021
Background Due to the low potential for primary biological healing of the anterior cruciate ligament (ACL), the most popular approach is currently reconstruction using a graft. Recent research indicates that the technique of strengthening a damaged ligament with synthetic tapes (internal bracing) may be an alternative to reconstructive treatment, especially in cases of partial ACL damage. Objectives To compare and evaluate the possibility of using a synthetic graft (Neoligaments or FiberTape) to treat partial lesions of the ACL. Material and methods This was a retrospective cohort study. Selected from a pool of 128 patients undergoing primary unilateral intra-articular ACL reconstruction du…
Emotional intelligence in Greek teacher education : Findings from a short intervention
2021
AbstractEmotional intelligence (EI) is widely known to be crucial for professional development in education, and it is a curricular component of Greek teacher education. Still, there is little information available on student teachers’ EI. The aim of this study was to explore whether student teachers’ trait EI can be developed through a two-week, EI-focused intervention. The study followed a quasi-experimental design with a mixed method approach, using the Trait Emotional Intelligence Questionnaire-Short Form (Greek version) (N = 42) and reflective emotion diaries (N = 19). The participants were third-year undergraduate students studying primary education and teaching at the University of C…
El papel de las mujeres en la historia según las imágenes de los libros de texto. Comparación de manuales editados durante la LOE y la LOMCE
2016
This paper focuses on the study of the role of women and its representation in the images of the textbooks of Environmental Knowledge and Social Sciences subjects, specifically in History topics. Textbooks can give us an overview of how women are presented in the historical discourse carried from Primary Education, and through their analysis we can see if it has or not an androcentric bias. Therefrom it’s developed an analysis and a comparison of the data between volumes of both last education laws implemented in Spain (LOE and LOMCE).
Parental Competence in Infant and Primary Education: design and validation of an instrument
2021
Actualmente, la familia se encuentra ante retos que requieren de su eficiencia y eficacia en la crianza, protección y orientación de los hijos, es decir, la parentalidad y la capacidad de los padres de ejercerla de forma competente. Desde este punto de vista, destaca la necesidad de un modelo educativo centrado en el desarrollo de las competencias parentales que proporcione conocimientos, habilidades y actitudes que optimicen el rol parental respecto al desarrollo pleno y sistémico del ser humano. Ante la necesidad de conocer si los padres asumen de forma óptima su papel en la educación de sus hijos, se plantea como objetivo principal de este artículo el diseño de un instrumento para el aná…
