A performance index of football teams: the Spanish case
(Chile. Universidad Mayor, 2021)In this article, we propose an index to measure the performance of the Spanish Football league most important teams during the 2016/2017 season. Using data from 10 Spanish first division football clubs, and principal ... -
A Project Based Learning Approach for Teaching Artificial Intelligence to Undergraduate Students
(Chile. Universidad MayorTempus Publications, 2020)This work presents an active learning methodology called Project-based learning (PBL) for developing artificial intelligence (AI) in a computer vision course of an undergraduate engineering degree. The objective of the ... -
A Prunus persica genome-wide RNA-seq approach uncovers major differences in the transcriptome among chilling injury sensitive and non-sensitive varieties
(WILEY, 2019)Chilling injury represents a major constrain for crops productivity. Prunus persica, one of the most relevant rosacea crops, have early season varieties that are resistant to chilling injury, in contrast to late season ... -
A Qualitative Study of a Mindfulness-Based Intervention in Educational Contexts in Chile: An Approach Based on Adolescents' Voices
(MDPI, 2020)The application of mindfulness-based interventions in school settings has increased considerably in recent years, showing that differences between the characteristics of programmes can impact on the receptivity and ... -
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 relic of the past: current genetic patterns of the palaeoendemic tree Nothofagus macrocarpa were shaped by climatic oscillations in central Chile
(Oxford University Press, 2020-10)Background and Aims The Mediterranean-type forest of central Chile is considered a 'biodiversity hotspot' and a relic of a wider ancient distribution produced by past climatic oscillations. Nothofagus macrocarpa. commonly ... -
A Revised View of the LSU Gene Family: New Functions in Plant Stress Responses and Phytohormone Signaling
(MDPI, 2023-02)LSUs (RESPONSE TO LOW SULFUR) are plant-specific proteins of unknown function that were initially identified during transcriptomic studies of the sulfur deficiency response in Arabidopsis. Recent functional studies have ... -
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 ... -
A semi-automatic tool for the connectivity tracking of neuronal processes acquired using electron microscopy
(Public Library of Science, 2015)We describe an image processing tool for helping to organize, annotate and map neuronal circuitry. The tools use high-resolution images serially acquired via scanning electron microscopy (SEM). First, various image processing ... -
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. ... -
A standardized objective structured clinical examination to assess clinical competencies in medical students
(SOC MEDICA SANTIAGO, 2018)Background: Outcomes-based education is a trend in medical education and its assessment is one of the main challenges. The Objective Structured Clinical Examination (OSCE) is one of the tools used to assess clinical ... -
A synergy of the nutritional additives taurine and silymarin in salmon farming: evaluation with the CHSE-214 cellular model
(Springer Netherlands, 2020-06)The use of additives in the feed industry for producing fish has become the focus of constant change and research. The formulation of a product as a feeding strategy leads to the use of more than one molecule with particular ... -
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 ... -
A typology of prescription drug monitoring programs: a latent transition analysis of the evolution of programs from 1999 to 2016
(WILEY, 2019)Background and aims Prescription drug monitoring programs (PDMP), defined as state-level databases used in the United States that collect prescribing information when controlled substances are dispensed, have varied ... -
Aberrant localization of ezrin correlates with salivary acini disorganization in Sjogren's Syndrome
(CIENCIAS, 2010)OBJECTIVES: To analyse whether the alterations in the structure and organization of microvilli in salivary acinar cells from SS patients are linked to changes in the expression and/or cellular localization of ezrin. METHODS: ... -
Aberrant localization of fusion receptors involved in regulated exocytosis in salivary glands of Sjogren's syndrome patients is linked to ectopic mucin secretion.
(Facultad de Ciencias, 2012)Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease that mainly affects tear and salivary glands, whereby SS-patients frequently complain of eye and mouth dryness. Salivary acinar cells of SS-patients ... -
Aberrant MUC1 accumulation in salivary glands of Sjogren's syndrome patients is reversed by TUDCA in vitro
(Oxford University Press, 2020-04)Objectives. Xerostomia in SS patients has been associated with low quality and quantity of salivary mucins, which are fundamental for the hydration and protection of the oral mucosa. The aim of this study was to evaluate ...
