Copper-polyurethane composite materials : Particle size effect on the physical-chemical and antibacterial properties
(2020-09)In this work, thermoplastic polyurethane (TPU) composites incorporated with 1.0 wt% Cu particles were synthesized by the melt blending method. The effect of the incorporated copper particle size on the antibacterial, ... -
Free radicals derived from γ-radiolysis of water and AAPH thermolysis mediate oxidative crosslinking of eGFP involving Tyr-Tyr and Tyr-Cys bonds : the fluorescence of the protein is conserved only towards peroxyl radicals
(2020-04)The enhanced green fluorescent protein (eGFP) is one of the most employed variants of fluorescent proteins. Nonetheless little is known about the oxidative modifications that this protein can undergo in the cellular milieu. ... -
Learning-Based Neural Dynamic Surface Predictive Control for MMC
(2023-01-01)Reinforcement learning technique was developed recently as an interesting topic in designing adaptive optimal controllers. This technique explicitly provided a feasible solution to circumvent the 'curse of dimensionality' ... -
Relationship between nutritional status and sleep duration in Chilean school-age children
(2017-01-01)Objective: To establish the relationship between sleep duration, nutritional status and caffeinated beverage consumption patterns in school-age Chilean children. Method: The study was conducted in 805 schoolage children, ... -
Low-Complexity Finite Set Model Predictive Control for Split-Capacitor ANPC Inverter With Different Levels Modes and Online Model Update
(2023-02-01)In this article, an improved finite-control-set model predictive control (FCS-MPC) is presented for an active neutral point clamped (ANPC) topology. The considered converter significantly reduces the required power electronics ... -

Infecciones parasitarias en trasplantados renales
(1989-09)We performed indirect hemagglutination tests for toxoplasmosis and Chagas disease, complement fixation test for toxoplasmosis, stool examination for parasites and Graham test for enteroparasites in 51 patients before and ... -
Global, regional, and national consumption of animal-source foods between 1990 and 2018 : findings from the Global Dietary Database
(2022-03)Background: Diet is a major modifiable risk factor for human health and overall consumption patterns affect planetary health. We aimed to quantify global, regional, and national consumption levels of animal-source foods ... -
Trichostatin a promotes the generation and suppressive functions of regulatory T cells
(2013)Regulatory T cells are a specific subset of lymphocytes that suppress immune responses and play a crucial role in the maintenance of self-tolerance. They can be generated in the thymus as well as in the periphery through ... -
Molecular implications of adenosine in obesity
(2017-06)Adenosine has broad activities in organisms due to the existence of multiple receptors, the differential adenosine concentrations necessary to activate these receptors and the presence of proteins able to synthetize, degrade ... -
An improved photovoltaic maximum power point tracking technique-based model predictive control for fast atmospheric conditions
(2023-01-15)In this article, an enhanced maximum power point tracking (MPPT) technique for photovoltaic (PV) systems is presented. The proposed MPPT is designed for fast-changing operating conditions, where the conventional methods ... -
Renin-angiotensin system activation and interstitial inflammation in human diabetic nephropathy
(2003-10)Background. The molecular mechanisms of renal injury in diabetic nephropathy (DN) are not completely understood, although inflammatory cells play a key role. The renin-angiotensin system (RAS) is involved in kidney damage; ... -
Correction to : Effect of g-C3N4 on structural, optical, and photocatalytic properties of hexagonal cylinder-like twinned ZnO microcrystals prepared by the hydrothermal method (Journal of Materials Science: Materials in Electronics, (2021), 32, 19, (24095-24106), 10.1007/s10854-021-06872-9)
(2022-09)The authors regret that the published version of the article contained errors in Fig. 5 [1]. The correct and final version is given below as Fig. 1. -
“Mujeres espartanas” : heroísmo femenino, nacionalismo y guerra en Chile (1879-1929)
(2022-09)The article examines, from the perspective of the cultural history of the war, the role played by Chilean women in the War of the Pacific (1879-1883) and the social recognition of their actions. The paper examines the ... -
Deformación de la aleta caudal en alevín de salmón del atlántico (Salmo salar), en etapa de saco vitelino
(2020-12)This study analyzes the deformity of Atlantic salmon fry (Salmo salar) caudal fin, which gives it a "pointed tail" appearance. Although at hatching specimens were normal, the deformities were detected later. The objective ... -
Characterization and expression analysis of Nod-like receptor 3 (NLRC3) against infection with Piscirickettsia salmonis in Atlantic salmon
(2021-01)The nucleotide binding oligomerization domain like receptors, or NOD like receptors (NLRs), are intracellular receptors responsible for recognizing pathogens in vertebrates. Several NLR mammalian models have been characterized ... -
Asociación entre la conducta alimentaria y polimorfismos genéticos de la leptina y su receptor en niños obesos chilenos
(2015-10-03)Introduction: Leptin (LEP) is mainly produced in adipose tissue and acts in the hypothalamus to regulate energy intake. Mutations in the LEP gene or its receptor (LEPR) that produce monogenic obesity are infrequent. However, ... -
TNF-a-activated eNOS signaling increases leukocyte adhesion through the S-nitrosylation pathway
(2021-12)Nitric oxide (NO) is a key factor in inflammation. Endothelial nitric oxide synthase (eNOS), whose activity increases after stimulation with proinflammatory cytokines, produces NO in endothelium. NO activates two pathways: ... -
