Spatio-Temporal Variation of the Urban Heat Island in Santiago, Chile during Summers 2005-2017
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)
Urban heat islands (UHIs) can present significant risks to human health. Santiago, Chile has around 7 million residents, concentrated in an average density of 480 people/km(2). During the last few summer seasons, the highest ...
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)
One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ...
Axonal Degeneration in AD: The Contribution of A beta and Tau
(Frontiers Media S.A., 2020-10)
Alzheimer's disease (AD) represents the most common age-related neurodegenerative disorder, affecting around 35 million people worldwide. Despite enormous efforts dedicated to AD research over decades, there is still no ...
Comparison of self-report versus accelerometer - measured physical activity and sedentary behaviors and their association with body composition in Latin American countries
(Public Library of Science, 2020-04)
Background: Most population-based studies from Latin America have used questionnaires to measure physical activity (PA) and sedentary behaviors (SB). Low reliability and validity of the questionnaires has limited the ...
Comparison of two different frailty measurements and risk of hospitalisation or death from COVID-19: findings from UK Biobank
(BioMed Central Ltd., 2020-11)
Background Frailty has been associated with worse prognosis following COVID-19 infection. While several studies have reported the association between frailty and COVID-19 mortality or length of hospital stay, there have ...
Nivel de actividad física y sedentarismo en personas con diagnóstico de cáncer en Chile
(Sociedad Medica de Santiago, 2020-02)
Background: One of the side effects of cancer treatment is a low level of physical activity (PA) due to fatigue and pain. Aim: To quantify PA levels in Chilean people with cancer. Material and Methods: Analysis of the ...
Physical capability markers used to define sarcopenia and their association with cardiovascular and respiratory outcomes and all-cause mortality: A prospective study from UK Biobank
(Elsevier Ireland Ltd, 2020-08)
Introduction: It is unclear what combinations of physical capability markers used to define sarcopenia have the strongest associations with health outcomes. Aim: To compare the associations between different combinations ...
Short-term effects of variable-density thinning on regeneration in hardwood-dominated temperate rainforests
(Chile. Universidad Mayor, 2020-05)
Second-growth temperate forests usually have simpler composition and structure than comparable old-growth stands. We evaluated the application of variable density thinning (VDT) as a way to increase old-growth attributes, ...
Collateral Sprouting of Peripheral Sensory Neurons Exhibits a Unique Transcriptomic Profile
(Humana Press, 2020-10)
Peripheral nerve injuries result in motor and sensory dysfunction which can be recovered by compensatory or regenerative processes. In situations where axonal regeneration of injured neurons is hampered, compensation by ...
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
(Elsevier, 2020-11)
The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ...
