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
(ELSEVIER, 2018)Objective: To investigate whether the association between type 2 diabetes (T2D) and family history of diabetes is modified by the levels of physical activity in the Chilean population. Method: In this study were included ... -
Risk of cognitive impairment among older people with diabetes or family history of the disease
(SOC MEDICA SANTIAGO, 2018)Background: Although cardiovascular risk factors are associated with an impaired cognitive function, the impact of diabetes on cognitive function in Chilean adults is unknown. Aim: To investigate the association of diabetes ... -
Levels of physical activity and excess body weight in university students
(SOC MEDICA SANTIAGO, 2018)Background: University students are considered a vulnerable group due to their adoption of unhealthy diets and lifestyles. Aim: To determine the main risk factors associated with low level of physical activity and excess ... -
