On the nature of the enzyme–substrate complex and the reaction mechanism in human Arginase I. A combined molecular dynamics and QM/MM study
(2020)
We present here a complete detailed theoretical analysis of l-arginine hydrolysis catalyzed by human arginase I (HARGI). Our study combines classical molecular dynamics (MD) simulations of different models for the ...
GPU tensor cores for fast arithmetic reductions
(2021)
This article proposes a parallel algorithm for computing the arithmetic reduction of $n$ numbers as a set of matrix-multiply accumulate (MMA) operations that are executed simultaneously by GPU tensor cores. The analysis, ...
Mining social networks to improve suicide prevention: a scoping review
(2020)
Attention about the risks of online social networks (SNs) has been called upon reports describing their use to express emotional distress and suicidal ideation or plans. On the Internet, cyberbullying, suicide pacts, ...
Early motor reactivity to observed human body postures is affected by body expression, not gender
(2020)
The early response to emotional stimuli involves a transient suppression of motor reactivity to favor monitoring of emotionally relevant information. Using transcranial magnetic stimulation (TMS), we have previously shown ...
Four weeks of neuromuscular training improve static and dynamic postural control in overweight and obese children: a randomized controlled trial
(2020)
Thirty-two children with overweight or obesity were randomly divided into a neuromuscular training group (NTG) (n = 16) and a control group (CG) (n = 16). All individuals participated in the measurement of static postural ...
Does type of sponsorship of randomized controlled trials influence treatment effect size estimates in rehabilitation: a meta-epidemiological study
(2020)
Background: Sponsorship bias could affect research results to inform decision makers when using the results of these trials. The extent to which sponsorship bias affect results in the field of physical therapy has been ...
Association between cholinesterase's inhibition and cognitive impairment: a basis for prevention policies of environmental pollution by organophosphate and carbamate pesticides in Chile
(2020)
Background: In Chile organophosphate pesticides are widely used in the production of fruits. Pesticides use is regulated for professional practice but there is no regulation regarding exposure to the general population.

Novel microsatellite markers for an endangered freshwater snail, heleobia atacamensis (caenogastropoda: cochliopidae), from the Atacama Saltpan
(2020)
The minute freshwater gastropod Heleobia atacamensis is only known from its type locality Tilopozo, located at the southern end of the Atacama Saltpan, Antofagasta Region, Chile. It is classified as Critically Endangered ...
Physical capability markers used to define sarcopenia and their association with cardiovascular and respiratory outcomes and all-cause mortality: a prospective study from UK biobank
(2020)
Introduction: It is unclear what combinations of physical capability markers used to define sarcopenia have the strongest associations with health outcomes. Aim: To compare the associations between different combinations ...
Proposal of competencies for engineering education to develop water infrastructure based on “nature-based solutions” in the urban context
(2020)
The aim of this work was to determine the competencies that need to be included in engineering programs to develop water infrastructure based on Nature-Based Solutions (NBS) in the urban context, focused on its application ...
