(Oxford University Press, 2001)Relative growth rates, basal and acclimated thermotolerance, membrane damage, fluorescence emission, and relative levels of free and conjugated ubiquitin and HSP70 were compared after 2 h of treatment at different temperatures ...
-
(Sociedad Chilena Química, 2016)RIVER flows have constant interaction between water and bed sediments; for this reason knowledge of the characteristics of the sediments is fundamental to understand water chemistry. This study determined the concentrations ...
-
(Springer, 2017)In this study, we analyze the concentration of ten metals in two freshwater fish-the benthic catfish Trichomycterus areolatus and the limnetic silverside Basilichthys microlepidotus-in order to detect possible accumulation ...
-
(2013)Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and ...
-
(2004)Stem cells are crucial for normal development and homeostasis, and their misbehavior may be related to the origin of cancer. Progress in these areas has been difficult because the mechanisms regulating stem cell lineages ...
-
(American Institute of Physics, 2020)We have compared the magnetic properties of well-controlled ultra-short (<= 50nm) atomic iron (Fe) chains embedded in Fe-phthalocyanine films with those in Fe-hydrogen (H-2) phthalocyanine superlattices. Surprisingly, we ...
-
(1999)We have investigated the solution conformation of the functionally relevant C-terminal extremes of α- and β-tubulin, employing the model recombinant peptides RL52α3 and RL33β6, which correspond to the amino acid sequences ...
-
(Wiley, 2017)Alzheimer's disease (AD) is characterized by extracellular senile plaques, intracellular neurofibrillary tangles, and neuronal death. Aggregated amyloid-beta (A beta) induces inflammation and oxidative stress, which have ...
-
(2007)Forest fragmentation alters plant-animal interactions, including herbivory. Relying manipulative experiments, we test if the reduction in insect herbivory associated with forest fragmentation translates into increased ...
-
(SOCIEDAD BIOLGIA CHILE, 2006)Levels of body iron should be tightly controlled to prevent the formation of oxygen radicals. lipoperoxidation. genotoxicity, and the production of cytotoxic cytokines, which result in damage to a number of organs. Enterocytes ...
-
(2011)We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the ...
-
(WILEY-BLACKWELL, 2010-11)Two forms of the squat lobster Pleuroncodes monodon can be found along the Pacific coast of South America: a smaller pelagic and a larger benthic form that live respectively in the northern and southern areas of the ...
-
(American Chemical Society, 2017)© 2017 American Chemical Society.The aromatic fractions of snow, lake sediment, and air samples collected during 2011-2014 in the Athabasca oil sands region were analyzed using two-dimensional gas chromatography following ...
-
(2009)The vomeronasal system (VNS) of rodents participates in the regulation of a variety of social and sexual behaviours related to semiochemical communication. All rodents studied so far possess two parallel pathways from the ...
-
(Frontiers Media, 2022)Prolonged changes in neural activity trigger homeostatic synaptic plasticity (HSP) allowing neuronal networks to operate within functional ranges. Cell-wide or input-specific adaptations can be induced by pharmacological ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2011)Heterozygote deficiencies in natural populations of outbreeding tree species are common and thought to be due mainly to biparental inbreeding. Inbreeding is believed to be caused by family structure within populations, a ...
-
(Elsevier B.V., 2018)© 2018 British Mycological SocietyNumerous endoxylanases from mesophilic fungi have been purified and characterized. However, endoxylanases from cold-adapted fungi, especially those from Antarctica, have been less studied. ...
-
(2016)Background: The presence of exotic plants increases the heterospecific pollen (HP hereafter) received by native plants and reduces their reproductive output. Aims: We assessed whether the exotic herb Echium vulgare ...
-
(Elsevier, 2017)The fungus Penicillium camemberti is widely used in the ripening of various bloomy-rind cheeses. Several properties of P. camemberti are important in cheese ripening, including conidiation, growth and enzyme production, ...
-
(Oxford University Press, 2020)Heterozygosity-fitness correlations (HFCs) have been used to monitor the effects of inbreeding in threatened populations. HFCs can also be useful to investigate the potential effects of inbreeding in isolated relict ...
