(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2014)This paper analyzes the historical antecedents of pisco (grape brandy) in Chile from unpublished original documents of the Archivo Nacional (National Archives) from the end of the 17th century to the beginning of the 18th ...
-
(2011)The Notch signaling pathway plays an important role in development and physiology. In Drosophila, Notch is activated by its Delta or Serrate ligands, depending in part on the sugar modifi cations present in its extracellular ...
-
(Frontiers Media, 2020)Successful completion of sensory decision-making requires focusing on relevant stimuli, adequate signal/noise ratio for stimulus discrimination, and stimulus valence evaluation. Different brain regions are postulated to ...
-
(MDPI, 2022)In this work, a comprehensive view of the route that led to the construction of a theoretical approach to the functioning of DSSC is presented. The model was developed based on the theoretical interpretation of experimental ...

(Frontiers Research Foundation, 2017)© 2017 Rojas-Aedo, Gil-Durán, Del-Cid, Valdés, álamos, Vaca, García-Rico, Levicán, Tello and Chávez. Penicillium roqueforti is a filamentous fungus involved in the ripening of several kinds of blue cheeses. In addition, ...
-
(2002)It is shown that the topological analysis of the electron localization function (ELF), a measure of the local Pauli repulsion, is a useful tool to describe the bonding nature of transition structures of simple pericyclic ...
-
(Biomed Central, 2013)CaMKII is a major synaptic protein that is activated during the induction of long-term potentiation (LTP) by the Ca2+ influx through NMDARs. This activation is required for LTP induction, but the role of the kinase in the ...
-
(1992)Using a λgt10 cDNA library obtained from Xenopus laevis oocytes and probes derived from the known sequences of the human and Drosophila genes, a cDNA coding for the α-subunit of the X. laevis casein kinase II was isolated. ...
-
The centrifugal visual system of a palaeognathous bird, the Chilean Tinamou (Nothoprocta perdicaria) (Wiley, 2017-08)The avian centrifugal visual system, which projects from the brain to the retina, has been intensively studied in several Neognathous birds that have a distinct isthmo-optic nucleus (ION). However, birds of the order ...
-
(Elsevier, 2018)The type II chaperonin CCT is involved in the prevention of the pathogenesis of numerous human misfolding disorders, as it sequesters misfolded proteins, blocks their aggregation and helps them to achieve their native ...

-
(Taylor & Francis, 2016)The killifish Orestias ascotanensis is endemic to the small isolated springs of Ascotan salt pan in the Central High Andes, Chile. Due to small populations, mining activity, and increasing aridity, this species is catalogued ...
-
(Taylor and Francis, 2015)The killifish genus Orestias is endemic to freshwater ecosystems in the High Andes of Peru, Bolivia and Chile. Phylogenetic and phylogeographic studies with partial mitochondrial genes have failed to resolve relationship ...
-
(Taylor & Francis, 2016)Cheilodactylus variegatus is a common benthivorous marine fish inhabiting in rocky subtidal habitats in the eastern south Pacific coast of Chile and Peru. However, its biology and ecology are relatively understudied and ...
-
(Academic Press Inc., 2000)The organization of the cytoskeleton in the early first interphase zygote and its involvement in organelle redistribution were studied in the glossiphoniid leech Theromyzon trizonare by confocal and electron microscopy, ...
-
(Life Science Alliance, 2022)Actin filament polymerization can be branched or linear, which depends on the associated regulatory proteins. Competition for actin monomers occurs between proteins that induce branched or linear actin polymerization. ...
