Co-existence and switching between fast and Omega-slow wind solutions in rapidly rotating massive stars
(OXFORD UNIV PRESS, 2018)Most radiation-driven winds of massive stars can be modelled with m-CAK theory, resulting in the so-called fast solution. However, the most rapidly rotating stars among them, especially when the rotational speed is higher ... -
Core non-coding RNAs of Piscirickettsia salmonis
(PUBLIC LIBRARY SCIENCE, 2018)Piscirickettsia salmonis, a fastidious Gram-negative intracellular facultative bacterium, is the causative agent o Piscirickettsiosis. P. salmonis has broad host range with a nearly worldwide distribution, causing significant ... -
A Carbohydrate Moiety of Secreted Stage-Specific Glycoprotein 4 Participates in Host Cell Invasion by Trypanosoma cruzi Extracellular Amastigotes
(FRONTIERS MEDIA SA, 2018)Trypanosoma cruzi is the etiologic agent of Chagas' disease. It is known that amastigotes derived from trypomastigotes in the extracellular milieu are infective in vitro and in vivo. Extracellular amastigotes (EAs) have a ... -
Evaluation of frequency of antibodies against Toxoplasma gondii, Neospora caninum and Sarcocystis spp. and transmission routes in sheep from Humid Pampa, Argentina
(WALTER DE GRUYTER GMBH, 2018)The aim of this study was to describe the frequency of ovine specific antibodies to Toxoplasma gondii, Neospora caninum and Sarcocystis spp. and to estimate different transmission routes of these infections. One hundred ... -
Impaired IRE1 alpha/XBP-1 pathway associated to DNA methylation might contribute to salivary gland dysfunction in Sjogren's syndrome patients
(OXFORD UNIV PRESS, 2018)Objectives. Labial salivary glands (LSGs) of SS patients show alterations related to endoplasmic reticulum stress. Glandular dysfunction could be partly the consequence of an altered inositol-requiring enzyme 1 alpha (IRE1 ... -
Distributional ecology of Andes hantavirus: a macroecological approach
(BIOMED CENTRAL LTD, 2018)Background: Hantavirus pulmonary syndrome (HPS) is an infection endemic in Chile and Argentina, caused by Andes hantavirus (ANDV). The rodent Oligoryzomys longicaudatus is suggested as the main reservoir, although several ... -
Variation of the alkaloid content of Peumus boldus (boldo)
(ELSEVIER SCIENCE BV, 2018)Eighteen alkaloids were detected in the bark, leaves, wood and roots of Peumus boldus, including traces of secoboldine, N-methylsecoboldine (boldine methine), glaucine and norreticuline, not reported previously as constituents ... -
Influence of fatigue and velocity on the latency and recruitment order of scapular muscles
(CHURCHILL LIVINGSTONE, 2018)Objectives: To determine the influence of velocity and fatigue on scapular muscle activation latency and recruitment order during a voluntary arm raise task, in healthy individuals. Design: Cross-sectional study. Setting: ... -
Risk factors associated with type 2 diabetes in Chile
(ARAN EDICIONES, S L, 2018)Background: worldwide, prevalence of type 2 diabetes has doubled in the last years, mainly due to unhealthy lifestyle behaviours. They are many risk factors associated with diabetes, however, which factors are associated ... -
Association of physical inactivity with obesity, diabetes, hypertension and metabolic syndrome in the chilean population
(SOC MEDICA SANTIAGO, 2018)Background: Physical inactivity is an important cardiovascular risk factor. Aim: To investigate the association of physical inactivity with obesity, metabolic markers, type 2 diabetes mellitus, hypertension and metabolic ... -
Understanding Chemical Reactivity in Extended Systems: Exploring Models of Chemical Softness in Carbon Nanotubes
(PEKING UNIV PRESS, 2018)Chemical reactivity towards electron transfer is captured by the Fukui function. However, this is not well defined when the system or its ions have degenerate or pseudo-degenerate ground states. In such a case, the first-order ... -
Rational Development of a Novel Hydrogel as a pH-Sensitive Controlled Release System for Nifedipine
(MDPI, 2018)This work depicts the rational development (in-silico design, synthesis, characterization and in-vitro evaluation) of polyvinyl alcohol hydrogels (PVAH) cross-linked with maleic acid (MA) and linked to gamma-cyclodextrin ... -
Bioleaching of Arsenic-Bearing Copper Ores
(MDPI, 2018)World copper (Cu) production has been strongly affected by arsenic (As) content, because As-rich Cu concentrates are not desirable in the metal foundries. When As-rich Cu concentrates are processed by smelting they release ... -
Reciprocal grafting between clones with contrasting drought tolerance suggests a key role of abscisic acid in coffee acclimation to drought stress
(SPRINGER, 2018)The role of abscisic acid (ABA) in drought tolerance of Coffea canephora is unknown. To determine whether ABA is associated with drought tolerance and if the use of tolerant rootstocks could increase ABA and drought ... -
Impact of Hypothermic Stress During Special Operations Training of Chilean Military Forces
(OXFORD UNIV PRESS, 2018)Introduction: The Chilean Army considers processes that can optimize physical capacities for responding to the impact of situations and given stressors. The study of the effect of hypothermia as a stressor agent (HSA) and ... -
Galactic or extragalactic chemical tagging for NGC3201? Discovery of an anomalous CN-CH relation
(EDP SCIENCES S A, 2018)Context. The origin of the globular cluster (GC) NGC 3201 is under debate. Its retrograde orbit points to an extragalactic origin, but no further chemical evidence supports this idea. Light-element chemical abundances are ... -
DENDROECOLOGICAL APPROACH TO ASSESSING CARBON ACCUMULATION DYNAMICS IN TWO PINUS SPECIES FROM NORTHERN MEXICO
(TREE-RING SOC, 2018)Global climate change will alter forests by shifting species ranges, which has implications for their ecological functions. Annual tree-ring widths andwood density are useful proxies for carbon cycle studies across a range ... -
Association between type 2 diabetes and physical activity in individuals with family history of diabetes
