Exploring the Effect of the Irradiation Time on Photosensitized Dendrimer-Based Nanoaggregates for Potential Applications in Light-Driven Water Photoreduction
(MDPI, 2019)
Fourth generation polyamidoamine dendrimer (PAMAM, G4) modified with fluorescein units (F) at the periphery and Pt nanoparticles stabilized by L-ascorbate were prepared. These dendrimers modified with hydrophobic fluorescein ...
Film Dressings Based on Hydrogels: Simultaneous and Sustained-Release of Bioactive Compounds with Wound Healing Properties
(MDPI, 2019)
This research proposes the rational modeling, synthesis and evaluation of film dressing hydrogels based on polyvinyl alcohol crosslinked with 20 different kinds of dicarboxylic acids. These formulations would allow the ...
A decentralized route to the origins of scaling in human language
(IOP PUBLISHING LTD, 2019)
Zipf's law establishes that if the words of a (large) text are ordered by decreasing frequency, the frequency versus the rank decreases as a power law with exponent close to -1. Previous work has stressed that this statistical ...
Original research Socio-demographic patterning of self-reported physical activity and sitting time in Latin American countries: findings from ELANS
(BMC, 2019)
Background: Low levels of physical activity (PA) and prolonged sitting time (ST) increase the risk of non-communicable diseases and mortality, and can be influenced by socio-demographic characteristics. The aim of this ...
Adaptation to milking agropastoralism in Chilean goat herders and nutritional benefit of lactase persistence
(WILEY, 2019)
The genetic trait of lactase persistence (LP) evolved as an adaptation to milking pastoralism in the Old World and is a well-known example of positive natural selection in humans. However, the specific mechanisms conferring ...
Novel and Convenient Synthesis of 2,7-Dialkyl-1,8-dihydro- as -indacenes
(GEORG THIEME VERLAG KG, 2019)
A novel and convenient synthetic route towards dialkyl as -indacenes was achieved by alkylation of malonic esters with o -xylylene dibromide, to give the corresponding tetraester, and related diacid. The alkyl groups on ...

Adiposity, healthy lifestyle and physical activity levels in housewives and women with paid employment in Chile
(SOC CHILENA NUTRICION, BROMATOLOGIA & TOXICOLOGIA, 2019)
Lifestyle behaviours among women who take care of their home duties (housewives) and women who are currently working in paid employment is unknown in the Chilean population. The aim of this study was, therefore, to ...
Characterization of polyphenol profile of extracts obtained from grape pomace and synergistic effect of these extracts and fungicides against Botrytis Cinerea
(SOC CHILENA QUIMICA, 2019)
Botrytis cinerea is a phytopathogenic fungus that infects the aerial parts of approximately 250 plant species. Control of this fungus is based on synthetic fungicide application. However, it has been reported the detection ...
Inhibition-Disruption of Candida glabrata Biofilms: Symmetrical Selenoesters as Potential Anti-Biofilm Agents
(MDPI, 2019)
Candida glabrata is one of the most prevalent pathogenic Candida species in dental plaque on tooth surfaces. Candida biofilms exhibit an enhanced resistance against most antifungal agents. Thus, the development of alternative ...
