The effects of positive human contact by tactile stimulation on dairy cows with different personalities
(ELSEVIER SCIENCE BV, 2018)The understanding of the ways in which cows with different personalities perceive human contact is essential for improving the quality of the human-animal relationship and therefore the welfare of dairy cows. The general ... -
Changes in sperm function and structure after freezing in domestic cat spermatozoa
(WILEY, 2018)Sperm cryopreservation allows for a long-term storage of genetic. However, changes due to factors as cold shock, osmotic and oxidative stress cause reduction in viability and fertilising ability of frozen/thawed spermatozoa. ... -
Association of high 5-hydroxymethylcytosine levels with Ten Eleven Translocation 2 overexpression and inflammation in Sjogren's syndrome patients
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)Here, we determined the 5-hydroxymethylcytosine (5hmC), 5-methylcytosine (5mC), Ten Eleven Translocation (TETs), and DNA methyltransferases (DNMTs) levels in epithelial and inflammatory cells of labial salivary glands (LSG) ... -
Arsenic removal mediated by acidic pH neutralization and iron precipitation in microbial fuel cells
(ELSEVIER SCIENCE BV, 2018)High concentrations of arsenic (As) in natural waters are a growing concern worldwide. In northern Chile, fluvial systems enriched in As from natural and anthropogenic sources have been found to contain microbial communities ... -
Ideal Cardiovascular Health and Incident Cardiovascular Disease Among Adults: A Systematic Review and Meta-analysis
(ELSEVIER SCIENCE INC, 2018)Objective: To investigate the association between ideal cardiovascular health (CVH) metrics and incident cardiovascular disease (CVD) by conducting a systematic review and meta-analysis of prospective cohort studies. ... -
MLSTar: automatic multilocus sequence typing of bacterial genomes in R
(PEERJ INC, 2018)Multilocus sequence typing (MLST) is a standard tool in population genetics and bacterial epidemiology that assesses the genetic variation present in a reduced number of housekeeping genes (typically seven) along the genome. ... -
Endoplasmic reticulum stress in autoimmune diseases: Can altered protein quality control and/or unfolded protein response contribute to autoimmunity? A critical review on Sjogren's syndrome
(ELSEVIER SCIENCE BV, 2018)For many years, researchers in the field of autoimmunity have focused on the role of the immune components in the etiopathogenesis of autoimmune diseases. However, some studies have demonstrated the importance of target ... -
Prediction of drought-induced reduction of agricultural productivity in Chile from MODIS, rainfall estimates, and climate oscillation indices
(ELSEVIER SCIENCE INC, 2018)Global food security is negatively affected by drought. Climate projections show that drought frequency and intensity may increase in different parts of the globe. These increases are particularly hazardous for developing ... -
Joint effect of physical activity and sedentary behaviour on cardiovascular risk factors in Chilean adults
(OXFORD UNIV PRESS, 2018)Background To investigate the associations between combined categories of moderate-to-vigorous physical activity (MVPA) and sedentary behaviour (SB) with markers of adiposity and cardiovascular risk in adults. Methods ... -

Water-equivalence of gel dosimeters for radiology medical imaging
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)International dosimetry protocols are based on determinations of absorbed dose to water. Ideally, the phantom material should be water equivalent; that is, it should have the same absorption and scatter properties as water. ... -
Bolidophyceae, a Sister Picoplanktonic Group of Diatoms - A Review
(FRONTIERS MEDIA SA, 2018)Pico- and nano-phytoplankton (respectively, 0.2-2 and 2-20 mu m in cell size) play a key role in many marine ecosystems. In this size range, Bolidophyceae is a group of eukaryotes that contains species with cells surrounded ... -

Association of a healthy lifestyle index with cardiovascular risk factors in Chileans adults
(SOC MEDICA SANTIAGO, 2018)Background: Healthy lifestyles are associated with a better metabolic- and cardiovascular health profile. Aim: To investigate the association between a lifestyle score and cardiovascular risk in Chilean adults. Material ... -
Knee sensorimotor control following anterior cruciate ligament reconstruction: A comparison between reconstruction techniques
(PUBLIC LIBRARY SCIENCE, 2018)The sensorimotor system helps to maintain functional joint stability during movement. After anterior cruciate ligament (ACL) injury and reconstruction, several sensorimotor deficits may arise, including altered proprioception ... -
Association of the FTO (rs9939609) genotype with energy intake
(SOC MEDICA SANTIAGO, 2018)Background: Fat-mass-associated-gene (FTO) is associated with higher energy intake and specific food preferences. Aim: To investigate the association of the FTO genotype with energy intake, macronutrient and alcohol ... -
An Empirical Study of Exhaustive Matching for Improving Motion Field Estimation
(MDPI, 2018)Optical flow is defined as the motion field of pixels between two consecutive images. Traditionally, in order to estimate pixel motion field (or optical flow), an energy model is proposed. This energy model is composed of ... -
