(FEDERACION ESPANOLA ASOC DOCENTES EDUCACION FISICA-FEADEF, 2023-05-24)Introducción: La práctica regular de actividad física (AF) es reconocida por su efecto en la salud. Durante, la formación universitaria, surge la sobrecarga académica. Los objetivos de este estudio son 1). Determinar las ... -
Nivel de actividad física y sedentarismo en personas con diagnóstico de cáncer en Chile
(Sociedad Medica de Santiago, 2020-02)Background: One of the side effects of cancer treatment is a low level of physical activity (PA) due to fatigue and pain. Aim: To quantify PA levels in Chilean people with cancer. Material and Methods: Analysis of the ... -
Niveles de actividad física y tiempo sedente según ingreso económico en Chile: resultados de la Encuesta Nacional de Salud 2016-2017
(Chile. Universidad Mayor, 2021-10)Background: The Chilean population reports high levels of physical inactivity. The relationship between income level, physical activity (PA) and sedentary behaviors is not well known. Aim: To describe the levels of PA and ... -
Niveles de hormonas tiroideas en recien nacidos muy prematuros y prematuros extremos
(Facultad de Ciencias, 2018)Introducción: La función tiroidea del prematuro se ve alterada por la relativa inmadurez del eje hipotálamo-hipófisis-tiroides, junto a otros factores como la incidencia de enfermedades o el uso de algunos fármacos. ... -

NMDA receptor subunit composition controls dendritogenesis of hippocampal neurons through CAMKII, CREB-P, and H3K27ac
(Wiley-Liss Inc., 2017)Dendrite arbor growth, or dendritogenesis, is choreographed by a diverse set of cues, including the NMDA receptor (NMDAR) subunits NR2A and NR2B. While NR1NR2B receptors are predominantly expressed in immature neurons and ... -
No such thing as a free lunch: interaction costs and the structure and stability of mutualistic networks
(WILEY, 2020)Different modelling approaches have been used to relate the structure of mutualistic interactions with the stability of communities. However, inconsistencies arise when we compare modelling outcomes with the patterns of ... -
Non-canonical function of IRE1 alpha determines mitochondria-associated endoplasmic reticulum composition to control calcium transfer and bioenergetics
(NATURE PUBLISHING GROUP, 2019)Mitochondria-associated membranes (MAMs) are central microdomains that fine-tune bioenergetics by the local transfer of calcium from the endoplasmic reticulum to the mitochondrial matrix. Here, we report an unexpected ... -
Non-coding RNAs and chromatin: key epigenetic factors from spermatogenesis to transgenerational inheritance
(Chile. Universidad Mayor, 2021-12-28)Cellular fate and gene expression patterns are modulated by different epigenetic factors including non-coding RNAs (ncRNAs) and chromatin organization. Both factors are dynamic throughout male germ cell differentiation on ... -
Non-lysosomal Activation in Macrophages of Atlantic Salmon (Salmo salar) After Infection With Piscirickettsia salmonis
(FRONTIERS MEDIA SA, 2019)Piscirickettsia salmonis is a facultative intracellular pathogen and etiological agent of the systemic disease salmonid rickettsial septicemia. It has been suggested that P salmonis is able to survive in host macrophages, ... -

Non-Specific Antibodies Induce Lysosomal Activation in Atlantic Salmon Macrophages Infected by Piscirickettsia salmonis
(Frontiers Media S.A., 2020-11)Piscirickettsia salmonis, an aggressive intracellular pathogen, is the etiological agent of salmonid rickettsial septicemia (SRS). This is a chronic multisystemic disease that generates high mortalities and large losses ... -
Non-trophic interactions strengthen the diversity-functioning relationship in an ecological bioenergetic network model
(PUBLIC LIBRARY SCIENCE, 2019)Ecological communities are undeniably diverse, both in terms of the species that compose them as well as the type of interactions that link species to each other. Despite this long recognition of the coexistence of multiple ... -
Nonlinear optomechanical resonance entering a self-organized energy transfer pattern
