Las células satélites (CSs), son progenitores miogénicos quiescentes responsables de la regeneración muscular durante la adultez. Ante un daño muscular, las CSs se activan, proliferan y finalmente se diferencian. Este proceso es sostenido por la expresión secuencial de factores reguladores de mús...
Satellite cells (SCs) are quiescent myogenic progenitors responsible for skeletal muscle regeneration during adult life. Upon muscle damage, SCs activate, proliferate and finally differentiate; a process supported by the sequential expression of muscle regulatory factors (MRFs) and the down-regul...
In this thesis, the vulnerability and capacity of acclimation to environmental stress related to
Climate change mainly in Cystoseira tamariscifolia and other species as Ellisolandia elongata,
Cystoseira compressa and Padina pavonica are evaluated. The effects of physical stressors
as elevated irr...
Viruses are ubiquitous in all environments and hot-springs are not the exception even though its extreme conditions. Phototrophic mats of terrestrial hot-springs have been used for decades as models for understanding the composition, structure, and function of microbial communities in nature. The...
Los virus son ubicuos en todos los entornos y las fuentes termales no son la excepción a pesar de sus condiciones extremas. Los tapetes fototróficoss de las fuentes termales terrestres se han utilizado durante décadas como modelos para comprender la composición, estructura y función de las comuni...
Discarding Antarctic and sub Antarctic regions, the Andes concentrate almost 90% of glacier cover in the Southern Hemisphere. Large data gaps exist here, preventing detailed knowledge on how climate determines glacier behavior. As Andean glaciers are distributed in a latitudinal transect spanning...
Heap bioleaching technology has been successfully applied at an industrial scale for over 30 years, and is generally considered to be the most effective engineering option to bio-process low-grade copper sulfide ores. Heap bioleaching was established at the Escondida mine in Chile in 2006, and cu...
Se evaluó el consumo y sostenibilidad de la huella hídrica de la agricultura (HHagrícola) desarrollada en la cuenca del río Cachapoal, divida en tres secciones: alta, media y baja. Se utilizó como indicadores la huella hídrica azul (HHazul) y verde (HHverde), correspondiente al agua consumida com...
In this thesis, a midlatitude climatology of cut-off lows was done and then used for studying the synoptic-scale patterns associated with extreme rainfall rate events due to the passage of cut-off lows in central Chile. The climatology was developed using the NCEP-NCAR reanalysis data from 1960 t...
La bacteria Pseudomonas veronii R4 aislada desde la rizósfera de vid, presenta alta actividad nematicida sobre Xiphinema index. Este nemátodo es el vector del virus de la hoja de abanico de la vid, el agente viral más importante que afecta este cultivo. P. veronii R4 está relacionado filogenética...
The bacterium Pseudomonas veronii R4 isolated from grapevine rhizosphere, possess high nematicide activity against Xiphinema index. This nematode is the vector of the grapevine fanleaf virus, the most significant viral agent that affects this crop. P. veronii R4 is phylogenetically related to P. ...
Amphibian populations are in general decline internationally. The current situation of amphibian populations highlights the urgent need for comprehensive information on species’ ecology to better assess conservation and management strategies. Movement behaviour and microhabitat selection give ins...
Internacionalmente, las poblaciones de anfibios están en declive. La situación actual de las poblaciones de anfibios resalta la urgente necesidad de más información sobre la ecología de especies para lograr una mejor evaluación de las estrategias de conservación y manejo. Los estudios de movimien...
In the southern zone of the Humboldt Current System (HCS), the upwelling process, the nutrient-rich Equatorial Subsurface Water transported by the Peru-Chile Subsurface Current (PCUC), and the nutrient advection dynamics are known to be crucial factors to generate the high biological productivity...
En la zona sur del Sistema de Corrientes de Humboldt (SCH), el proceso de surgencia, el Agua Ecuatorial Subsuperficial rica en nutrientes transportada por la Corriente Subsuperficial Chile-Perú (PCUC), y la dinámica de advección de los nutrientes, son factores cruciales para la generación de la a...
