Tree-ring-based hydroclimatic reconstruction for the northwest Argentine Patagonia since 1055 CE and its teleconnection to large-scale atmospheric circulation
(ELSEVIER, 2021-07)
State-of-the-art climate models project droughts of stronger intensity and longer persistence in many arid and semi-arid regions such as northern Patagonia, which constitutes a serious concern worldwide. Moisture availability ...
Enhanced Activity of Exportin-1/CRM1 in Neurons Contributes to Autophagy Dysfunction and Senescent Features in Old Mouse Brain
(HINDAWI LTD, 2021-08-16)
Brain aging is characterized by dysfunctional autophagy and cellular senescence, among other features. While autophagy can either promote or suppress cellular senescence in proliferating cells, in postmitotic cells, such ...
Nutritional status and sweet taste preference in Chilean adults
(ARCHIVOS LATINOAMERICANOS NUTRICION, 2020-12)
El dramático aumento de la prevalencia e incidencia de la obesidad sugiere que factores ambientales y cambios en el estilo de vida contribuyen de forma importante a su tendencia epidémica. En humanos, se han reportado ...
Simulations of primary damage in a High Entropy Alloy: Probing enhanced radiation resistance
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-07)
High Entropy Alloys (HEA) attract attention as possible radiation resistant materials, a feature observed in some experiments that has been attributed to several unique properties of HEA, in particular to the disorder-induced ...
Growth of male and female Araucaria araucana trees respond differently to regional mast events, creating sex-specific patterns in their tree-ring chronologies
(ELSEVIER, 2021-03)
Araucaria araucana is a dioecious evergreen conifer endemic from temperate forests of south Argentina and Chile. It is a long-lived species (maximum age > 1000 years), and it presents a high potential for tree-ring based ...
Seasonal precipitation in south-central Chile: Trends in extreme events since 1900
(UNAM. CENTRO CIENCIAS ATMOSFERA, 2021-09)
We study a regional precipitation time series built upon seven meteorological records from south-central Chile (SCC; 37 degrees-42 degrees S), which altogether cover the period 1900-2019. As a first objective, we investigated ...
High-Speed Bodyweight Resistance Training Improves Functional Performance Through Maximal Velocity in Older Females
(HUMAN KINETICS PUBL INC, 2021-08)
The authors compared the effects of bodyweight resistance training at moderate- or high-speed conditions on muscle power, velocity of movement, and functional performance in older females. In a randomized, single-blinded ...
