A regulatory RNA is involved in RNA duplex formation and biofilm regulation in Sulfolobus acidocaldarius
(OXFORD UNIV PRESS, 2018)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 ... -
A scoping systematic review of social stressors and various measures of telomere length across the life course
(ELSEVIER IRELAND LTD, 2018)Numerous studies examine the relationship between social stressors and telomere length (TL). Beyond considering methods and major findings, this scoping systematic review takes a novel approach as it groups studies according ... -
Surface electromyographic amplitude does not identify differences in neural drive to synergistic muscles
(AMER PHYSIOLOGICAL SOC, 2018)Surface electromyographic (EMG) signal amplitude is typically used to compare the neural drive to muscles. We experimentally investigated this association by studying the motor unit (MU) behavior and action potentials in ... -
ER Proteostasis Control of Neuronal Physiology and Synaptic Function
(ELSEVIER SCIENCE LONDON, 2018)Neuronal proteostasis is maintained by the dynamic integration of different processes that regulate the synthesis, folding, quality control, and localization of proteins. The endoplasmic reticulum (ER) serves as a fundamental ... -
Nutrient Transport Driven by Microbial Active Carpets
(AMER PHYSICAL SOC, 2018)We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent flows towards the substrate, and propose that these currents provide efficient pathways to replenish nutrients that feed back into ... -
Molecular mechanisms related to the hepatoprotective effects of antioxidant-rich extra virgin olive oil supplementation in rats subjected to short-term iron administration
(ELSEVIER SCIENCE INC, 2018)Enhanced iron levels in liver are associated with oxidative stress development and damage with increased fat accumulation. The aim of this work was to assess the hypothesis that antioxidant-rich extra virgin olive oil ... -
Drought and climate change incidence on hotspot Cedrela forests from the Mata Atlantica biome in southeastern Brazil
(ELSEVIER SCIENCE BV, 2018)The Atlantic Forest is a Neotropical biome encompassing mainly Brazil's coastline and parts of Paraguay, Uruguay, and Argentina, but today surviving largely in small degraded patches and protected areas. Being a region ... -
International meeting on sarcoptic mange in wildlife, June 2018, Blacksburg, Virginia, USA
(BMC, 2018)Sarcoptic mange is a globally distributed disease caused by the burrowing mite Sarcoptes scabiei, which also causes scabies in humans. A wide and increasing number of wild mammal species are reported to be susceptible to ... -
Can physical activity attenuate the negative association between sitting time and cognitive function among older adults? A mediation analysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)The purpose of this study was to examine the combined association of sitting time and physical activity with cognitive function and to determine whether moderate-to-vigorous physical activity (MVPA) is a mediator of the ... -
Bartonella vinsonii subsp. berkhoffii and B. henselae in dogs
(CAMBRIDGE UNIV PRESS, 2018)This study aimed to molecularly survey Bartonella in dogs from Chile. Quantitative real-time PCR (qPCR) for Bartonella spp. based on nuoG gene was performed in 139 blood samples taken from dogs belonging to rural localities ... -
A Tomato Tocopherol-Binding Protein Sheds Light on Intracellular alpha-Tocopherol Metabolism in Plants
(OXFORD UNIV PRESS, 2018)Tocopherols are non-polar compounds synthesized in the plastids, which function as major antioxidants of the plant cells and are essential in the human diet. Both the intermediates and final products of the tocopherol ... -
Patterns of healthy lifestyle behaviours in older adults: Findings from the Chilean National Health Survey 2009-2010
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)The purpose of this study was to investigate healthy lifestyle behaviours across age categories in the older population in Chile. Data from 1390 older adults (>= 60 years), in the 2009-2010 Chilean National Health Survey ... -
Changes in the ankle muscles co-activation pattern after 5 years following total ankle joint replacement
(ELSEVIER SCI LTD, 2018)Background: The Hintegra (R) arthroplasty provides inversion-eversion stability, permits axial rotation, ankle flexion-extension, and improvements of the gait patterns are expected up to 12 months of rehabilitation. However, ... -
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
(IOP PUBLISHING LTD, 2018)Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinearities of superconducting quantum circuits ... -
Motherhood inmigrant women in Chile: A qualitative study
(ELSEVIER SCI LTD, 2018)Background: The adverse impact of poverty and migration in pregnant women is expressed in diverse results in reproductive, mental and child health, all of which are related to lack of documentation to reside in the country, ... -
A Simulation Study Using Terrestrial LiDAR Point Cloud Data to Quantify Spectral Variability of a Broad-Leaved Forest Canopy
(MDPI, 2018)In this analysis, a method for construction of forest canopy three-dimensional (3D) models from terrestrial LiDAR was used for assessing the influence of structural changes on reflectance for an even-aged forest in Belgium. ... -
Evaluation of modeling strategies for assessing self-thinning behavior and carrying capacity
(WILEY, 2018)Self-thinning and site maximum carrying capacity are key concepts for understanding and predicting ecosystem dynamics as they represent the outcome of several fundamental ecological processes (e.g., mortality and growth). ... -
