Hematene: a 2D magnetic material in van der Waals or non-van der Waals heterostructures
(IOP PUBLISHING LTD, 2019)In this article, we study theoretically the properties of hematene, a new antiferromagnetic 2D material exfoliated from hematite. Hematene is not a van-der Waals material, but it can still be obtained by liquid exfoliation ... -
Repeated neonaticide: differences and similarities to single neonaticide events
(SPRINGER WIEN, 2019)This study aims to identify differences between single and repeat perpetrators of filicide by using register-based data. The study used register-based, comprehensive, nationwide data from both Austria and Finland. The ... -
High-fat diet induces mouse liver steatosis with a concomitant decline in energy metabolism: attenuation by eicosapentaenoic acid (EPA) or hydroxytyrosol (HT) supplementation and the additive effects upon EPA and HT co-administration
(ROYAL SOC CHEMISTRY, 2019)High-fat-diet (HFD) feeding is associated with liver oxidative stress (OS), n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) depletion, hepatic steatosis and mitochondrial dysfunction. Our hypothesis is that the ... -
The p75(NTR) neurotrophin receptor is required to organize the mature neuromuscular synapse by regulating synaptic vesicle availability
(BMC, 2019)The coordinated movement of organisms relies on efficient nerve-muscle communication at the neuromuscular junction. After peripheral nerve injury or neurodegeneration, motor neurons and Schwann cells increase the expression ... -
The association of grip strength with health outcomes does not differ if grip strength is used in absolute or relative terms: a prospective cohort study
(OXFORD UNIV PRESS, 2019)Background: higher grip strength is associated with better health outcomes. The optimal way to report grip strength (i.e. absolute vs. relative) for prediction, however, remains to be established. Methods: in participants ... -
Effect of diet and type of pregnancy on plasma metabolic response in sheep and its further effect on lamb performance
(SPRINGER, 2019)This trial evaluated the individual and interactional effects of diet and type of pregnancy (twin or single) on plasma metabolic response in ewes and their lambs from late pre-partum to late post-partum. Thus, a flock of ... -
Mechanical performance of lightweight polycrystalline Ni nanotubes
(ELSEVIER SCIENCE BV, 2019)The mechanical properties of metallic nanowires and nanotubes were investigated using atomistic molecular dynamics simulations on Ni polycrystalline structures, similar to those experimentally obtained by Atomic Layer ... -
Epidemiological characterization of bites: A retrospective study of dog bites to humans in Chile during 2009
(ELSEVIER SCIENCE INC, 2019)Accidents involving dog bites to humans have high incidence worldwide. According to studies conducted in different countries, dogs are responsible for 60%-95% of all bites. This type of incident is a growing public health ... -
Structure and vulnerability of the multi-interaction network in macrophyte-dominated lakes
(WILEY, 2020)The network approach is crucial to understand how ecosystems are structured and how they will respond to the disturbances (e.g. the current global change). We have recreated the multi-interaction network of a shallow ... -
Verticalización inmobiliaria y valorización de renta de suelo por infraestructura pública: un análisis econométrico del Gran Santiago, 2008-2011
(PONTIFICIA UNIV CATOLICA CHILE, INST ESTUDIOS URBANOS TERRITORIALES, 2019)Investments in public infrastructure and land upzoning aimed to high-rise redevelopment are both factors that considerably increase ground rent values in the city. Drawing on a dataset of new departments sold between 2008 ... -
Do Young People Adapt Their Prosocial Behaviour to That of Their Peers? An Experimental Exploration
(SAGE PUBLICATIONS LTD, 2019)Moral decisions - that is, decisions that consider the consequences for the welfare of others - can be highly inconsistent across contexts. Here, we explore whether the altruism of young people is related to their willingness ... -
Do physical activity, commuting mode, cardiorespiratory fitness and sedentary behaviours modify the genetic predisposition to higher BMI? Findings from a UK Biobank study
(NATURE PUBLISHING GROUP, 2019)Objective To investigate whether the association between a genetic profile risk score for obesity (GPRS-obesity) (based on 93 SNPs) and body mass index (BMI) was modified by physical activity (PA), cardiorespiratory fitness, ... -
Investigating how perceived risk and availability of marijuana relate to marijuana use among adolescents in Argentina, Chile, and Uruguay over time
(ELSEVIER IRELAND LTD, 2019)Aims: Amid changing marijuana policies in the Southern Cone, we examined relationships between marijuana related risk factors and marijuana use among adolescents in Argentina, Chile, and Uruguay from 2001 to 2016. Methods: ... -
Subtypes of minimal residual disease, association with Gleason score, risk and time to biochemical failure in pT2 prostate cancer treated with radical prostatectomy
(CANCER INTELLIGENCE LTD, 2019)Introduction: The Gleason score is a strong prognostic factor for treatment failure in pathologically organ-confined prostate cancer (pT2) treated by radical prostatectomy (RP). However, within each Gleason score, there ... -
Effect of FOLFOX on minimal residual disease in Stage III colon cancer and risk of relapse
(CANCER INTELLIGENCE LTD, 2019)Introduction: 25% of Stage III colon cancer patients relapse within 5 years due to minimal residual disease (MRD) not eliminated by surgery and chemotherapy. We hypothesise that sub-types of MRD, defined by circulating ... -
Non-trophic interactions strengthen the diversity-functioning relationship in an ecological bioenergetic network model
(PUBLIC LIBRARY SCIENCE, 2019)Ecological communities are undeniably diverse, both in terms of the species that compose them as well as the type of interactions that link species to each other. Despite this long recognition of the coexistence of multiple ... -
Communicating Branches Between the Median and Ulnar Nerves. Proposal for Inclusion in Terminologia Anatomica
(SOC CHILENA ANATOMIA, 2019)The ulnar and median nerves are widely distributed, innervating the muscles of the forearm and hand. In the latter, it also registers the sensitivity of a significant part of the skin. A series of communicating branches ... -
Optimizing synthetic diamond samples for quantum sensing technologies by tuning the growth temperature
(ELSEVIER SCIENCE SA, 2019)Control of the crystalline orientation of nitrogen-vacancy (NV) defects in diamond is here demonstrated by tuning the temperature of chemical vapor deposition (CVD) growth on a (113)-oriented diamond substrate. We show ... -
