(John Wiley and Sons Inc., 2016)© 2016 Wiley Periodicals, Inc. Neurons are highly polarized cells that contain specialized subcellular domains involved in information transmission in the nervous system. Specifically, the somatodendritic compartment ...
-
(International Society for Neurochemistry, 2014)Neuronal cells are characterized by the presence of two confined domains, which are different in their cellular properties, biochemical functions and molecular identity. The generation of asymmetric domains in neurons ...
-
(Society for Neuroscience, 2016)© 2016 the authors. Rab35 is a key protein for cargo loading in the recycling endosome. In neuronal immortalized cells, Rab35 promotes neurite differentiation. Here we describe that Rab35 favors axon elongation in rat ...

(1975)It is shown that the energy-momentum tensor of the electromagnetic field, for an electron in a curved space, may be split into two dynamically independent parts. One of them, the radiation tensor, has the following remarkable ...
-
(Elsevier, 2015)We examine the timing and magnitude of the last glacial maximum (LGM) and the last glacial termination (LGT) in northwestern Patagonia, situated in the middle latitudes of South America. Our data indicate that the main ...
-
(SOCIEDAD BIOLGIA CHILE, 2005)In this paper we develop a method to estimate lung Volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: ...
-
(Universidad de Chile., 1981)Se Estudió la acción de las radiaciones ionizantes sobre el agua y sistemas acuosos.
-
(SPRINGER, 2006-06)Tree presence in semiarid ecosystems is generally constrained by insufficient annual rainfall. However, in semiarid Chile, rainforest patches dominated by Aextoxicon punctatum are unexpectedly found on coastal mountaintops ...
-
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)Patterns in rainfall and soil water availability are considered to be the main drivers governing arid and semiarid ecosystems. While the mechanisms by which water limits aboveground net primary production has been widely ...
-
(John Wiley & Sons, 2013)The Raman and surface enhanced Raman scattering (SERS) spectra of a black dyed silk sample (BDS) were registered. The spectral analysis was performed on the basis of Raman and SERS spectral data of isolated samples of ...
-
(Pergamon-Elsevier, 2016)Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
-
(Sociedad Chilena de Quimica, 2015)The sensor 1-(4-mercaptophenyl)-2,4,6-triphenylpyridinium perchlorate compound was vibrationally characterized using Raman and the Surface-Enhanced Raman techniques, SERS and Shell-Isolated Nanoparticles-Enhanced Raman ...

-
(Johm Wiley, 2012)Important improvements of diseases of the rotator cuff supraspinatus tendons are seen after shock wave (SW) treatment. Neo-angiogenesis stimulation and hypercellularization result from short periods of treatment. The present ...
-
(Natl Inst R&D Materials Physics, 2020)CuIrSnS4, CuIrSnSe4 and CuIrSnS2Se2 were synthetized by a solid-state reaction at 700 degrees C. Powder X-ray diffraction patterns were consistent with normal spinel-type structure. Scanning electron microscopy (SEM-EDS) ...
-
(2014)A material characterization of two artworks discovered in the San Francisco Church, Santiago, Chile, was performed using micro-Raman spectroscopy. Structural painted beams and a wall painting that belong to the same time ...
