Protection of astaxanthin from photodegradation by its inclusion in hierarchically assembled nano and microstructures with potential as food
(Elsevier, 2018-10)Astaxanthin is a light sensitive molecule which is already approved as a dietary supplement, with a wide range of biological properties in humans and fishes. In this paper, we provide strategies to photostabilize the pigment ... -
Expression and function of TLR4-induced B1R bradykinin receptor on cardiac fibroblasts
(Elsevier, 2018-07-15)Cardiac fibroblasts (CF) are key cells for maintaining extracellular matrix (ECM) protein homeostasis in the heart, and for cardiac repair through CF-to-cardiac myofibroblast (CMF) differentiation. Additionally, CF play ... -

(Elsevier, 2018-09)"Hallulla" is a highly consumed type of Chilean bread, which may contain considerable amounts of some Neo-Formed Contaminants (NFCs). The objective of this research was to study the effect of tara (Caesalpinia spinosa) pod ... -
Assessment of industrial modules to design a GFMA process for cyanide recovery based on a phenomenological model
(MDPI, 2018-04)Cyanide recovery in the gold-mining industry is a crucial step in terms of the cost of operation. Currently, a process such as AVR (acidification, volatilization and recycling), based on packed towers for stripping and ... -
Mass transfer kinetic and quality changes during high-pressure impregnation (HPI) of jumbo squid (dosidicus gigas) slices
(Springer, 2018-08)Jumbo squid is an important marine resource commercialized in Chile as well as American countries such as PerA, Mexico, and USA. In order to find the best conditions for prevention of squid meat degradation, this study ... -
Erysodine, a competitive antagonist at neuronal nicotinic acetylcholine receptors, decreases ethanol consumption in alcohol-preferring UChB rats
(Elsevier, 2018-09)Alcohol abuse is a worldwide health problem with high economic costs to health systems. Emerging evidence suggests that modulation of brain nicotinic acetylcholine receptors (nAChRs) may be a therapeutic target for alcohol ... -
Effects of antimicrobial edible coating of thymol nanoemulsion/quinoa protein/chitosan on the safety, sensorial properties, and quality of refrigerated strawberries (fragaria × ananassa) under commercial storage environment
(Springer, 2018-08)The effectiveness of the edible coating with thymol nanoemulsion on the safety, sensorial properties, and quality of refrigerated strawberries was investigated under commercial storage conditions. Spontaneous emulsification ... -
Assessment of rheological and microstructural changes of soluble fiber from chia seeds during an in vitro micro-digestion
(Elsevier, 2018-09)The ability of some dietary fiber to increase the viscosity of digestive content may be associated with important positive implications in human health. An in vitro micro-digestion device was implemented to simulate and ... -

UHPLC-ESI-ORBITRAP-MS analysis of the native mapuche medicinal plant palo negro (leptocarpha rivularis DC. – asteraceae) and evaluation of its antioxidant and cholinesterase inhibitory properties
(Taylor & Francis, 2018)UHPLC/ESI/MS identification of organic compounds is the first step in the majority of screening techniques for the characterization of biologically active metabolites in natural sources. This paper describes a method for ... -
The effects of pressure on X-ray fluorescence analyses: pXRF under high altitude conditions
(Royal Soc. Chemistry, 2018-05)In Latin America many mine sites are located more than 2000 m above sea level, and some over 4000 m above sea level. Portable X-ray ray fluorescence (pXRF) is becoming a routine method for collecting chemical data at ... -
An infrared and SEM study of the margins of some german hyperinflation postage stamps
(RJPBCS Research Journal Pharmaceutical, Biological & Chemical Sciences, 2018-04)Infrared spectroscopy and scanning electron microscopy (SEM) studies were performed on the margins (the area without printed colors) of a set of German postage stamps dated 1923 and corresponding to the hyperinflationary ... -
Convective drying of osmo-treated abalone (haliotis rufescens) slices: diffusion, modeling, and quality features
(Wiley, 2018)The focus of this research was based on the application of an osmotic pretreatment (15% NaCl) for drying abalone slices, and it evaluates the influence of hot-air drying temperature (40-80 degrees C) on the product quality. ... -
Carboxymethylcellulose from bleached organosolv fibers of eucalyptus nitens: synthesis and physicochemical characterization
(Springer, 2018-05)The objective of the present study was to synthesize sodium carboxymethylcellulose from Eucalyptus nitens cellulose. The cellulose extraction was carried out in three stages. In the first stage, E. nitens wood was fractionated ... -
A regulatory RNA is involved in RNA duplex formation and biofilm regulation in sulfolobus acidocaldarius
(Oxford University Press, 2018-05-18)Non-coding RNAs (ncRNA) are involved in essential biological processes in all three domains of life. The regulatory potential of ncRNAs in Archaea is, however, not fully explored. In this study, RNA-seq analyses identified ... -
Matrix metalloproteinase 9 displays a particular time response to acute stress: variation in its levels and activity distribution in rat hippocampus
(ACS Publications, 2018-05)A single stress exposure facilitates memory formation through neuroplastic processes that reshape excitatory synapses in the hippocampus, probably requiring changes in extracellular matrix components. We tested the hypothesis ... -
Facile synthesis of graphene-AgVO3 nanocomposite with excellent supercapacitor performance
(Elsevier, 2018-06-15)The graphene-AgVO3 nanocomposites (GA30) were synthesized by facile one-step chemical-bath method. SEM and TEM images of the synthesized nanocomposites indicate that this method is possible to anchor the AgVO3 nanoparticles ... -
Exploring the influence of diels–alder linker length on photothermal molecule release from gold nanorods
