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 ...
