The role of local geochemical and mineralogical backgrounds as essential information to build efficient sediment quality guidelines at high-mountainous hydrothermally-altered basins (Mapocho basin, Chile)
(ELSEVIER, 2021-09-01)
The Mapocho River's upper basin (Chilean Central Andes) was studied as a proxy of a high-mountainous hydrothermally-altered (HMHA) system comprised by three sub-basins developed over very different rocks and submitted to ...
TGA class II transcription factors are essential to restrict oxidative stress in response to UV-B stress in Arabidopsis
(OXFORD UNIV PRESS, 2021-02-27)
Plants possess a robust metabolic network for sensing and controlling reactive oxygen species (ROS) levels upon stress conditions. Evidence shown here supports a role for TGA class II transcription factors as critical ...
Active School Breaks and Students' Attention: A Systematic Review with Meta-Analysis
(MDPI, 2021-06)
School physical activity breaks are currently being proposed as a way to improve students' learning. However, there is no clear evidence of the effects of active school breaks on academic-related cognitive outcomes. The ...
Changes over 15 years in the contribution of adiposity and smoking to deaths in England and Scotland
(BMC, 2021-02-11)
Background For many years smoking has been the major threat to public health in developed countries. However, smoking prevalence has declined over a period when adiposity has increased. The aim of this study was to determine ...

Estimating the degree of non-Markovianity using machine learning
(AMER PHYSICAL SOC, 2021-02-24)
In the last few years, the application of machine learning methods has become increasingly relevant in different fields of physics. One of the most significant subjects in the theory of open quantum systems is the study ...
Antisense noncoding mitochondrial RNA-2 gives rise to miR-4485-3p by Dicer processing in vitro
(SOC BIOLGIA CHILE, 2021-10-19)
Background The antisense noncoding mitochondrial RNAs (ASncmtRNAs) derive from the mitochondrial 16S gene. Knockdown of these transcripts with chemically-modified antisense oligonucleotides induces proliferative arrest, ...
BIOVERA-Tree: tree diversity, community composition, forest structure and functional traits along gradients of forest-use intensity and elevation in Veracruz, Mexico
(PENSOFT PUBLISHERS, 2021-09-09)
Here, we describe BIOVERA-Tree, a database on tree diversity, community composition, forest structure and functional traits collected in 120 forest plots, distributed along an extensive elevational gradient in Veracruz ...
IRE1α RIDD activity induced under ER stress drives neuronal death by the degradation of 14-3-3 θ mRNA in cortical neurons during glucose deprivation
(SPRINGER NATURE, 2021-06-03)
Altered protein homeostasis is associated with neurodegenerative diseases and acute brain injury induced under energy depletion conditions such as ischemia. The accumulation of damaged or unfolded proteins triggers the ...
