Analysis of primary language competition through ICT

Este artículo muestra el uso de las TIC para la mejora de la competencia lingüística de los estudiantes de Educación Primaria. Desde un diseño cuasi-experimental, la muestra conformada por 34 estudiantes de tercer ciclo de Educación Primaria de diferentes centros educativos en la comunidad andaluza, se ha dividido en dos grupos, grupo de control y grupo experimental, con la medición de la variable competencia lingüística a través de un cuestionario pretest-postest (? = ,821). A través del análisis estadístico para muestras independientes T de Student, los resultados muestran diferencias significativas en la variable de competencia lingüística (t=2,506; p=0.017) obteniendo un mayor valor en el grupo experimental. En conclusión, se mejora la competencia lingüística con las TIC en las rutinas aprendizaje.This article shows the use of ICTs for the improvement of Primary Education students' linguistic competence. From a quasi-experimental design, the sample made up of 34 students of the third cycle of Primary Education from different educational centers in the Andalusian community, has been divided into two groups, the control group and the experimental group, with the measurement of the linguistic competence variable through a pretest-postest questionnaire (? =, 821). Through statistical analysis for independent Student's T samples, the results showed significant differences in the linguistic competence variable (t = 2.506; p = 0.017), obtaining a higher score in the experimental group. In conclusion, the linguistic competence improves when the ICT is applied in learning routines

Survival of patients receiving a liver transplant for hepatocellular carcinoma, and risk of tumor recurrence

Objective: the goal of this research has been to evaluate the survival, in long and short term, of the patient receiving liver transplant for hepatocellular carcinoma (HCC), the risk of posttransplant tumor relapse and factors related to this complication. Design: retrospective study of a consecutive series of patients having had liver transplant for HCC. Patients and methodology: transplant patients for HCC from 1989 to November 2003. Patients were selected due to general limitations of nodule size and quantity, which were subsequently published as Milan criteria. Also, criteria agreed in the Conference of Barcelona were followed in the pre-transplant diagnosis. Results: the survival of this 81 patients group was of the 80, 61 and 52% for 1, 5 and 10 years respectively. In the 32% of the cases the HCC was an incidental finding in the explant. In the 12.3%, the tumor relapse was verified. The multivariate research identified the size of the nodule (OR = 1,7944) (IC 95% = 1,1332-2,8413) and the vascular invasion (OR = 6,6346) (IC 95% = 1,4624-30,1003) as risk factors of relapse. Conclusions: the liver transplant in selected patients with HCC has good results in medium and long term. The risk of post-transplant tumor relapse becomes notably reduced and is associated with the size of the nodule and the microscopic vascular invasion

Programa de Tutorías Personalizadas en la Licenciatura de Química

Son muchas las novedades a las que se enfrenta el estudiante a su llegada a la Universidad. Acostumbrados a un grupo reducido de amigos y profesores del instituto local, la Universidad les abre la posibilidad inquietante de salir por primera vez de casa, de conocer nuevos compañeros y amigos, de conocer nuevas formas de enseñanza y estudio, de relacionarse con gente de diversas nacionalidades y profesión.Por todo esto, conscientes por nuestra experiencia con alumnos de cursos anteriores de que todas estas novedades no serán fáciles de asimilar y avalados por los informes de evaluación de la Titulación de Química de la UJA (interno y externo), que detectan importantes deficiencias en el proceso de enseñanza-aprendizaje, un grupo de profesores de la Universidad hemos considerado interesante y especialmente formativo ofrecer a los alumnos nuestra ayuda en la forma de un servicio de tutorización personalizado, mediante el cual y desde una perspectiva más cercana se puedan mejorar todos estos aspectos

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

Revista Actualidad Criminológica nº3

Nuestra revista nace con vocación de servir a dos objetivos: a) divulgativo, dar a conocer la ciencia criminológica al público en general y al estudiante universitario en particular y, b) generador de un espacio de encuentro y reflexión de profesores y alumnos de la Universidad Camilo José Cela. A través de sus páginas pretendemos servir de escaparate de una realidad que se escapa al ciudadano de a pié, del fenómeno de la criminalidad en todas sus manifestaciones, de su cruda realidad, de la lucha contra el delito, del estudio y la investigación criminal, del método científico como herramienta básica de trabajo

Sex differences in oncogenic mutational processes

Efforts to link these clinical differences to specific molecular features have focused on somatic mutations within the coding regions of the genome. Here we report a pan-cancer analysis of sex differences in whole genomes of 1983 tumours of 28 subtypes as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium. We both confirm the results of exome studies, and also uncover previously undescribed sex differences. These include sex-biases in coding and non-coding cancer drivers, mutation prevalence and strikingly, in mutational signatures related to underlying mutational processes. These results underline the pervasiveness of molecular sex differences and strengthen the call for increased consideration of sex in molecular cancer research
