Tofacitinib counteracts IL-6 overexpression induced by deficient autophagy: implications in Sjogren's syndrome
(OXFORD UNIV PRESS, 2021-05-25)Objective. Altered homeostasis of salivary gland (SG) epithelial cells in Sjogren's syndrome (SS) could be the initiating factor that leads to inflammation, secretory dysfunction and autoimmunity. Autophagy is an important ... -
Tomato Cultivars With Variable Tolerances to Water Deficit Differentially Modulate the Composition and Interaction Patterns of Their Rhizosphere Microbial Communities
(FRONTIERS MEDIA SA, 2021-07-13)Since drought is the leading environmental factor limiting crop productivity, and plants have a significant impact in defining the assembly of plant-specific microbial communities associated with roots, we aimed to determine ... -
Tools for risk assessment of acute and chronic effects due to metal and metalloid exposition
(SPRINGER HEIDELBERG, 2018)The global situation of environmental exposure, sometimes metallic, remains latent at present and increases when it comes to natural disasters, mayor use and difficulties in waste management, so that the tools to establish ... -
Top Incomes in Chile: A Historical Perspective on Income Inequality, 1964-2017
(WILEY, 2019)We present a novel series of Chilean top-income shares covering half a century, mainly based on income-tax declarations and the National Accounts. Such a time frame of analysis is still rare in the literature of developing ... -
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
(AMER CHEMICAL SOC, 2018)Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ... -
Towards a Fiscal Sociology of Latin America
(Centro de Estudios y Documentacion Latinoamericanos (CEDLA), 2019-01)Los sistemas tributarios en América Latina se caracterizan por una baja recaudación, una mayor incidencia de impuestos y mecanismos regresivos, poca redistribución y un bajo cumplimiento. Los diseñadores de políticas y ... -
Towards an analytical description of active microswimmers in clean and in surfactant-covered drops
(Chile. Universidad Mayor, 2020)Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow. Based on a far-field analytical model, ... -
Tracing Mapuche Exclusion from Post-Dictatorial Truth Commissions in Chile: Official and Grassroots Initiatives
(OXFORD UNIV PRESS, 2018)This article critically examines the official misrecognition of Mapuche experiences of violence during Augusto Pinochet's dictatorship (1973-1990) in state-sponsored truth commissions in Chile. We examine official ... -
Tracing the phylogenetic history of the Crl regulon through the Bacteria and Archaea genomes
(BMC, 2019)Background: Crl, identified for curli production, is a small transcription factor that stimulates the association of the sigma(S) factor (RpoS) with the RNA polymerase core through direct and specific interactions, increasing ... -
