La expresión oral en los libros de texto

El libro de texto es uno de los principales materiales educativos que se utilizan en los centros escolares. Por ello, analizar estos manuales muestra en gran medida la forma en la que las diferentes competencias son trabajadas en el aula. En el estudio llevado a cabo se analiza la parte de expresión oral de la competencia comunicativa en las cuatro editoriales más utilizadas en los centros educativos de la etapa de Educación Primaria de Castilla y León, durante el curso académico 2021-2022. Las asignaturas analizadas son Lengua Castellana y Literatura, Matemáticas y Ciencias Sociales, observando las diferencias existentes tanto entre diferentes editoriales como entre distintas asignaturas en cuanto a las competencias que conforman la expresión oral.Grado en Educación Primari

Influence of Thickness on the Magnetic and Magnetotransport Properties of Epitaxial La0.7Sr0.3MnO3 Films Deposited on STO (0 0 1)

Epitaxial La0.7Sr0.3MnO3 films with different thicknesses (9–90 nm) were deposited on SrTiO3 (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties, which have been proven to be thickness dependent. Magnetic contributions with different switching mechanisms were evidenced, depending on the perovskite film thickness. The Curie temperature increases with the film thickness. In addition, colossal magnetoresistance effects of up to 29% above room temperature were evidenced and discussed in respect to the magnetic behavior and film thickness

Clinical Perspectives of Gut Microbiota in Patients with Chronic Kidney Disease and End-Stage Kidney Disease: Where Do We Stand?

The gut microbiota (GM) plays a vital role in human health, with increasing evidence linking its imbalance to chronic kidney disease and end-stage kidney disease. Although the exact methods underlying kidney-GM crosstalk are not fully understood, interventions targeting GM were made and lay in three aspects: diagnostic, predictive, and therapeutic interventions. While these interventions show promising results in reducing uremic toxins and inflammation, challenges remain in the form of patient-specific GM variability, potential side effects, and safety concerns. Our understanding of GMs role in kidney disease is still evolving, necessitating further research to elucidate the causal relationship and mechanistic interactions. Personalized interventions focusing on specific GM signatures could enhance patient outcomes. However, comprehensive clinical trials are needed to validate these approaches’ safety, efficacy, and feasibility
