(PERGAMON-ELSEVIER SCIENCE LTD, 2005-08)Pressure and temperature metamorphic conditions were determined for K-white mica and chlorite in metapelites from the eastern Andean metamorphic complex (EAMC) and from the Chonos metamorphic complex (CMC) of southern ...
-
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)In the Guarguaraz Complex of the Argentine Frontal Cordillera (latitude 33.3°S) serpentinite lenses, metabasites, and garnet-bearing metasedimentary rocks occur. The corresponding Devonian metamorphic event was assigned ...
-
(ELSEVIER, 2008-03)The geodynamic evolution of the proto-Andean margin of Gondwana during the Paleozoic was characterized by repeated subduction processes associated with the docking of several terranes, including the Cuyania-Precordillera ...
-
(Universidad de Chile, 2012)En la presente memoria se exponen los fundamentos que evidencian la inseguridad de las ciudades respecto a los riesgos que cada una posee, pretendiendo aminorar los daños humanos por medio de la prevención, con un proyecto ...

(Elsevier B.V., 2019)© 2018 Elsevier B.V. In mammals, the cochlear sensory epithelium becomes quiescent early during development. After the first postnatal week, there is no cell replacement or proliferation, and severe damage leads to permanent ...
-
(Association for Research in Otolaryngology, 2013)The cells in the organ of Corti do not exhibit spontaneous cell regeneration; hair cells that die after damage are not replaced. Supporting cells can be induced to transdifferentiate into hair cells, but that would ...
-
(Springer Berlin Heidelberg, 2008-01)In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers.We present distribution and fault tolerance ...
-
(2010-03-05)Volume-sensitive outwardly rectifying (VSOR) Cl channels are critical for the regulatory volume decrease (RVD) response triggered upon cell swelling. Recent evidence indicates that H2O2 plays an essential role in the ...
-
(MDPI, 2020)The P2X7 receptor is a ligand-gated, cation-selective channel whose main physiological ligand is ATP. P2X7 receptor activation may also be triggered by ARTC2.2-dependent ADP ribosylation in the presence of extracellular ...
-
(BIOMED CENTRAL LTD, 2011-02-15)Background: Working memory (WM) tasks usually elicit a P300 ERP component, whose amplitude decreases with increasing WM load. So far, this effect has not been studied in schizophrenics (SZs), a group that is considered to ...
-
(Wiley & Sons, 2015)CDK5 plays an important role in neurotransmission and synaptic plasticity in the normal function of the adult brain, and dysregulation can lead to Tau hyperphosphorylation and cognitive impairment. In a previous study, we ...

P450-aromatase activity and expression in human testicular tissues with severe spermatogenic failure (Blackwell Publishing Ltd, 2010)There is evidence that impaired spermatogenesis is associated with an imbalance in the oestradiol/testosterone ratio and with Leydig cell (LC) dysfunction. In testis, P450-aromatase, encoded by CYP19, is responsible for ...
