In vivo expansion of a CD9+ decidual-like NK cell subset following autologous hematopoietic stem cell transplantation.

Autologous hematopoietic stem cell transplantation (autoHSCT) is a treatment option for hematological disorders and pediatric solid tumors. After an autoHSCT, natural killer (NK) cells are the first lymphocyte subset returning to normal levels. To uncover global changes during NK cell reconstitution after autoHSCT, we performed RNA-sequencing on NK cells before and after autoHSCT. Results showed profound changes in the gene expression profile of NK cells immediately after autoHSCT. Several biological processes including cell cycle, DNA replication and the mevalonate pathway were enriched. Significantly, we observed that following autoHSCT, NK cells acquired a decidual-like gene expression profile, including the expression of CD9. By using multiparametric flow cytometry, we confirmed the expansion of NK cells expressing CD9 immediately after autoHSCT, which exhibited higher granzyme B and perforin expression levels than CD9- NK cells. These results provide insights into the physiopathology of NK cells during their reconstitution after autoHSCT.Supported by the following grants: AECC-Spanish Association Against Cancer (PROYE16074- BORR) and Health Department, Basque Government (2021333006).

Capitulo 2. Ciencias Naturales y Ciencias Básicas, Ingeniería y Tecnología

La diseminación de la Levitación Magnética, a pesar de lo antiguo de su tecnología, ha sido limitada. Debido a sus inconvenientes prácticos de implementación, su uso es bastante restringido, comparado con otras tecnologías (SCMaglev japonés, Transrapid alemán, o productos comerciales para ocio y entretenimiento). Con el boom de las tecnologías limpias y amigables con el medio ambiente y en concordancia con los objetivos del milenio, es pertinente plantearse el objetivo de optimizar el proceso de Levitación Magnética para generar un aprovechamiento de las ventajas de esta tecnología a nivel mecánico, eléctrico, y ambiental.  Actualmente la UNAD adelanta un proyecto de investigación cuyo objetivo es generar un modelo físico matemático de levitación magnética para aplicaciones en ingeniería. De este proyecto se ha derivado una primera revisión sistemática de los principios físicos y los modelos vigentes en Levitación Magnética

Apuntes de literatura infantil : cómo educar en la lectura

Esta obra comienza introduciendo al lector en la historia de la Literatura Infantil, los inicios del libro y la lectura, del romanticismo al cuento moderno, tendencias actuales, etc. A continuación matiza el valor de la lectura y su importancia en el currículum. El siguiente tema aborda los pasos previos a la lectura. El capítulo cuarto, espacios y tiempos de la lectura. Quinto capítulo, lugares para la lectura, escuela, animación esporádica y la familia como mediadora. Por último, los autores, destacan fórmulas para aborrecer la lectura y decálogos para crear cultura del libro.CantabriaES
