Changing fire regimes in the temperate rainforest region of southern Chile over the last 16,000 yr
(ELSEVIER, 2008)
A high-resolution macroscopic charcoal record from Lago Melli (42°46′S, 73°33′W) documents the occurrence of forest fires in the lowlands
of Isla Grande de Chiloé, southern Chile, over the last 16,000 yr. Our data suggest ...
Voltage-Gated K+/Na(+)Channels and Scorpion Venom Toxins in Cancer
(Frontiers Media, 2020)
Ion channels have recently been recognized as novel therapeutic targets in cancer research since they are overexpressed in different histological tissues, and their activity is linked to proliferation, tumor progression, ...
Topological Crystalline Insulator in a New Bi Semiconducting Phase
(NATURE PUBLISHING GROUP, 2016)
Topological crystalline insulators are a type of topological insulators whose topological surface states are protected by a crystal symmetry, thus the surface gap can be tuned by applying strain or an electric field. In ...
Geotectonic evolution of the Bransfield Basin, Antarctic Peninsula: insights from analogue models
(2008)
The Bransfield Strait, located between the South Shetland Islands and the north-western end of the
Antarctic Peninsula, is a back-arc basin transitional between rifting and spreading. We compiled a
geomorphological ...
Photoreduction of oxoisoaporphine dyes by amines: Transient-absorption and semiempirical quantum-chemical studies
(AMER CHEMICAL SOC, 2005-07-07)
Photoreduction by amines of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-proton electron transfer that leads to the metastable N-hydrogen oxoisoaporphine anion. During photoreduction that occurs from ...
Aging and health policies in Chile: new agendas for research
(Routledge, 2017)
Population aging is among the most important global transformations. Compared to European and North American countries, Chile is among the countries with the fastest growth of life expectancy at birth during recent decades. ...
Airborne Aerosols and Human Health: Leapfrogging from Mass Concentration to Oxidative Potential
(MDPI, 2020)
The mass concentration of atmospheric particulate matter (PM) has been systematically used in epidemiological studies as an indicator of exposure to air pollutants, connecting PM concentrations with a wide variety of human ...
Is floral diversification associated with pollinator divergence? Flower shape, flower colour and pollinator preference in chilean Mimulus
(OXFORD UNIV PRESS, 2008-04)
Background and Aims Adaptation to different pollinators is thought to drive divergence in flower colour and morphology, and may lead to interspecific reproductive isolation. Floral diversity was tested for association with ...
Why p-OMe- and p-Cl-beta-Methylphenethylamines Display Distinct Activities uponMAO-B Binding
(Public Library Science, 2016)
Despite their structural and chemical commonalities, p-chloro-beta-methylphenethylamine and p-methoxy-beta-methylphenethylamine display distinct inhibitory and substrate activities upon MAO-B binding. Density Functional ...
Basis set effects on B3LYP geometries and energies: case study of interstellar reaction HN=CH2 + •C≡N → H2N-C(•)H-C≡N
(2002)
To facilitate a rational basis set selection for B3LYP studies of organic reactions in the interstellar medium, we analyzed energetic parameters for the main stationary points in the reaction HN=CH2 + •C≡N → H2N-C(•)H-C≡N ...
