(HINDAWI LTD, 2021-03-14)Active immunotherapy against cancer is based on immune system stimulation, triggering efficient and long-lasting antigen-specific immune responses. Immunization strategies using whole dead cells from tumor tissue, containing ... -
Tofacitinib counteracts IL-6 overexpression induced by deficient autophagy: implications in Sjogren's syndrome
(OXFORD UNIV PRESS, 2021-05-25)Objective. Altered homeostasis of salivary gland (SG) epithelial cells in Sjogren's syndrome (SS) could be the initiating factor that leads to inflammation, secretory dysfunction and autoimmunity. Autophagy is an important ... -
Dysfunctional mitochondria as critical players in the inflammation of autoimmune diseases: Potential role in Sjo¨gren's syndrome
(ELSEVIER, 2021-07-23)Relevant reviews highlight the association between dysfunctional mitochondria and inflammation, but few studies address the contribution of mitochondria and mitochondria-endoplasmic reticulum (ER) contact sites (MERCs) to ... -
Municipal police support for harm reduction services in officer-led referrals of people who inject drugs in Tijuana, Mexico
(BMC, 2021-08-01)Background Police constitute a structural determinant of health and HIV risk of people who inject drugs (PWID), and negative encounters with law enforcement present significant barriers to PWID access to harm reduction ... -
School Memories of Preservice Teachers: An Analysis of Their Role in the Conceptions About the Relationships Between Emotions and Teaching/Learning Processes
(FRONTIERS MEDIA SA, 2021-10-13)With the aim of exploring the role of emotional elementary school memories that preservice teachers have, in their conceptions about the relationships between emotions and teaching-learning processes, a study was carried ... -
Parental care in male degus (Octodon degus) is flexible and contingent upon female care
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-09-01)Parents in many animal species provide care to their offspring as a mechanism to enhance their own fitness. In mammals, this behavior is expressed mostly by the females, but also by males of some species. Proximally, rates ... -
Sensitivity of Water Price Elasticity Estimates to Different Data Aggregation Levels
(SPRINGER, 2021-05-13)The empirical literature on residential water demand employs various data aggregation methods, which depend on whether the aggregation is over consumption, sociodemographic variables, or both. In this study, we distinguish ... -
Association of Vitamin D Receptor Polymorphisms with Amyloid-β Transporters Expression and Risk of Mild Cognitive Impairment in a Chilean Cohort
(IOS PRESS, 2021-07-15)Background: Amyloid-beta peptide (A beta) deposition in Alzheimer's disease (AD) is due to an imbalance in its production/clearance rate. Ap is transported across the blood-brain barrier by LRP1 and P-gp as efflux transporters ... -
Hypoxic Respiratory Chemoreflex Control in Young Trained Swimmers
(FRONTIERS MEDIA SA, 2021-03-29)During an apnea, changes in PaO2 activate peripheral chemoreceptors to increase respiratory drive. Athletes with continuous apnea, such as breath-hold divers, have shown a decrease in hypoxic ventilatory response (HVR), ... -
Effects of different resistance training frequencies on body composition and muscular performance adaptations in men
(PEERJ INC, 2021-05-24)Background: The aim of this study was to compare the effects of 8 weeks resistance training (RT) with two sessions versus four sessions per week under volume load-equated conditions on body composition, maximal strength, ... -
Influence of squeezing on the weak-to-strong measurement transition
(AMER PHYSICAL SOC, 2021-06-11)In this work, we study the measurement transition for a coherent squeezed pointer state through a transition factor Gamma that involves a system-pointer coupling by using an arbitrary measured observable A. In addition, ... -
Analytical solutions for radiation-driven winds in massive stars - II. The δ-slow regime
(OXFORD UNIV PRESS, 2021-04-29)Accurate mass-loss rates and terminal velocities from massive stars winds are essential to obtain synthetic spectra from radiative transfer calculations and to determine the evolutionary path of massive stars. From a ... -
Mechanical and structural assessment of CuZr metallic glasses rejuvenated by thermal-pressure treatments
(ELSEVIER, 2021-09-06)Thermal-pressure treatments have proved to bring metallic glasses (MGs) to rejuvenated states. However the knowledge regarding their effect on the mechanical properties and atomic structure is still limited. Here, molecular ... -
Cerebral aneurysm rupture status classification using statistical and machine learning methods
(SAGE PUBLICATIONS LTD, 2021-04-24)Morphological characterization and fluid dynamics simulations were carried out to classify the rupture status of 71 (36 unruptured, 35 ruptured) patient specific cerebral aneurysms using a machine learning approach together ... -
Effect of the atomic construction and preparation procedure on the deformation behaviour of CuZr metallic glasses
(TAYLOR & FRANCIS LTD, 2021-08-29)The construction of metallic glasses (MGs) at the atomic scale for molecular dynamics simulations involves several factors that ultimately affect the deformation behaviour, a matter that has been rarely addressed in the ... -
Time-Based Systems Biology Approaches to Capture and Model Dynamic Gene Regulatory Networks
(ANNUAL REVIEWS, 2021-07-19)All aspects of transcription and its regulation involve dynamic events. However, capturing these dynamic events in gene regulatory networks (GRNs) offers both a promise and a challenge. The promise is that capturing and ... -
Indentation and scratching of iron by a rotating tool-a molecular dynamics study
