-
(2012)Since the preferential body temperature should positively correlate with physiological performance, behavioural fever should enhance an organism's immune response under an immune challenge. Here we have studied the ...
-
(Universidad de Chile, 2015)The interactions between seismic activity, fluid flow and mineral precipitation exerts a first-order control on the strength and permeability of the crust and plays a critical role in promoting the development of hydrothermal ...
-
(Royal Soc Chemistry, 2015)By integrating the microarray expression data and a global E. faecalis transcriptional network we identified a sub-network activated by zinc and copper. Our analyses indicated that the transcriptional response of the ...
-
(The Company of Biologist, 2014)Mammals exposed to low temperatures increase their metabolic rate to maintain constant body temperature and thus compensate for heat loss. This high and costly energetic demand can be mitigated through thermoregulatory ...
-
(Frontiers Research Foundation, 2014)A growing set of observations points to mitochondrial dysfunction, iron accumulation, oxidative damage and chronic inflammation as common pathognomonic signs of a number of neurodegenerative diseases that includes Alzheimer's ...
-
(2004)The neural crest is a population of cells that originates at the interface between the neural plate and non-neural ectoderm. Here, we have analyzed the role that Notch and the homeoprotein Xiro1 play in the specification ...
-
(Universidad de Chile, 2021)Salinization and pollution (e.g., agrochemicals) are two main environmental stressors leading to degradation of aquatic ecosystems and consequently alteration in their biological communities. Amphibians are a highly ...
-
(Society of Biology of Chile, 2007)We studied the lung diffusion parameters of two species of birds and two species of mammals to explore how structural and functional features may be paralleled by differences in life style or phylogenetic origin. We used ...
-
(American Association for the Advancement of Science, 2014)The disruption of the energy or nutrient balance triggers endoplasmic reticulum (ER) stress, a process that mobilizes various strategies, collectively called the unfolded protein response (UPR), which reestablish homeostasis ...
-
(Elsevier, 2012)Although the study of thermoregulation in insects has shown that infected animals tend to prefer higher temperatures than healthy individuals, the immune response and energetic consequences of this preference remain ...
-
(American Physical Society, 2015)We study a one-dimensional binary optical lattice in the presence of diagonal disorder and alternating gain and loss, and examine the light transport phenomena for localized and extended input beams. In the pure PT ...
-
(Universidad de Chile, 2013)La temperatura es uno de los factores que determina las características del clima y es el principal regulador del funcionamiento de los ecosistemas terrestres. Una de las principales áreas de investigación de la temperatura ...

(American Ornithological Society, 2017)© 2017 American Ornithological Society. Nest morphology can affect the breeding success of birds. Thus, birds inhabiting different environments may experience divergent selection for nest structure and composition that ...
-
(Universidad de Chile, 2020)Con la entrada en vigencia gradual en las distintas regiones del país1 de la Ley N°20.322 que Fortalece y Perfecciona la Justicia Tributaria y Aduanera publicada en el diario oficial el 27 de enero de 2009, se incorporó ...
