Phosphorylation of Endothelin-Converting Enzyme-1c at Serines 18 and 20 by CK2 Promotes Aggressiveness Traits in Colorectal Cancer Cells
(2020-07-30)Endothelin-converting enzyme-1 (ECE1) activates the endothelin-1 peptide, which upregulates pathways that are related to diverse hallmarks of cancer. ECE1 is expressed as four isoforms differing in their N-terminal domains. ... -
Factores asociados al control metabòlico en pacientes chilenos con diabetes mellitus tipo 2
(2016-07-01)Background: Nowadays, the 8.3% of the adult population worldwide presents Diabetes Mellitus (DM), being estimated that in 2030 this disease will affect 9.9% of the population. The objective of this study is to determine ... -
Study of RNA-A Initiation Translation of The Infectious Pancreatic Necrosis Virus
(2017-08-15)The infectious pancreatic necrosis virus (IPNV) is a salmonid pathogen that causes significant economic losses to the aquaculture industry. IPNV is a non-enveloped virus containing two uncapped and non-polyadenylated double ... -
Factors predictive of serious infections over time in systemic lupus erythematosus patients : data from a multi-ethnic, multi-national, Latin American lupus cohort
(2019-08-01)Aim: The aim of this study was to identify factors predictive of serious infections over time in patients with systemic lupus erythematosus (SLE). Methods: A multi-ethnic, multi-national Latin American SLE cohort was ... -
Isolation and characterisation of mineral-oxidising “Acidibacillus” spp. from mine sites and geothermal environments in different global locations
(2016-09-01)Eight strains of acidophilic bacteria, isolated from mine-impacted and geothermal sites from different parts of the world, were shown to form a distinct clade (proposed genus “Acidibacillus”) within the phylum Firmicutes, ... -
Computationally guided synthesis of (2D/3D/2D) rGO/Fe2O3/g-C3N4 nanostructure with improved charge separation and transportation efficiency for degradation of pharmaceutical molecules
(2019-10-15)In this study, we designed and successfully prepared all solid state 2D/3D/2D rGO/Fe2O3/g-C3N4 nanocomposite by embedding 3D Fe2O3 nanoparticles on 2D g-C3N4 nanosheets to for 3D/2D Fe2O3/g-C3N4 followed by the addition ... -
Performance Evaluation of PV Model-Based Maximum Power Point Tracking Techniques
(2022-08)Maximum power point tracking (MPPT) techniques extract the ultimate power from the photovoltaic (PV) source. Therefore, it is a fundamental control algorithm in any PV configuration. The research in this area is rich and ... -
Spatio-temporal estimations of ultraviolet erythemal radiation in Central Chile
(2022-05)Solar ultraviolet radiation (UVR) plays an important role in environmental and occupational health. Although the importance of UVR and its spectral bands is well established, the characterization of spatio-temporal ... -
Event-Triggered Model Predictive Control for the Inverter of a Grid-connected Microgrid with a Battery-Supercapacitor HESS
(2022)This paper proposes an event-triggered model predictive control (ET-MPC) method for inverters to connect DC microgrids with battery-supercapacitor hybrid energy storage systems (HESS) to the grid. The procedure for creating ... -
Spatio-temporal analysis of chlorophyll in six Araucanian lakes of Central-South Chile from Landsat imagery
(2021-11)Chlorophyll-a (Chl-a) is an optically active compound commonly used as a proxy for phytoplankton biomass and trophic state in an aquatic system. This work aimed to analyze the spatiotemporal variation of Chl-a values in ... -
First description of clinical presentation of piscine orthoreovirus (PRV) infections in salmonid aquaculture in Chile and identification of a second genotype (Genotype II) of PRV
