(2011)The along-fjord variability of nitrate and dissolved silicate was studied in a silled fjord, Seno Ballena, in the Strait of Magellan during flood and ebb tidal phases in December 2007. The spatial and temporal variability ...
-
(Elsevier, 1999)The putative role of nitric oxide (NO) in the physiology of olfactory receptor neurons (ORNs) is controversial. Here we report that pulses of NO caused an outward current in voltage-clamped isolated olfactory neurons. The ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009-02-05)Nitric oxide regulates neurogenesis in the developing and adult brain. The olfactory epithelium is a site of neurogenesis in the adult and previous studies suggest a role for nitric oxide in this tissue during development. We ...
-
(1993)Voltammetric studies of nimodipine using a mixed aqueous dimethylformamide (DMF) solvent have allowed us to generate the one-electron reduction product, the nitro radical anion RNO2 .. The cyclic voltammetry technique has ...
-
(VCH Publishers. Inc., 1994)The cyclic voltammetric characteristics of two nitroamphetamine derivatives (2-nitro-4,5dimethoxyamphetamine and 2-nitro-4,5-methylenedioxyamphetamine) have been investigated in different media. In mixed media (aqueous ...

(1994)The cyclic voltammetric characteristics of two nitroamphetamine derivatives (2‐nitro‐4,5‐dimethoxyamphetamine and 2‐nitro‐4,5‐methylenedioxyamphetamine) have been investigated in different media. In mixed media (aqueous ...
-
(1998)Studies in unpolluted, old-growth forests in the coastal range of southern Chile (42°30′S) can provide a baseline for understanding how forest ecosystems are changing due to the acceleration of nitrogen (N) inputs that has ...
-
(Universidad de Chile, 2017-12)El contenido de Cd, Cu y Zn fue analizado en tejido blando de la lapa Fissurella sp., colectadas en abril de 2017 en la zona intermareal de la bahía de Chañaral, caleta Palito y caleta Pan de Azúcar, región de Atacama, ...
-
(Universidad de Chile, 2013)Hibridación e ¡ntrogres¡ión son fenómenos bastante documentados en plantas, pero limitada a unos pocos taxa animales. En poblaciones naturales, las zonas híbridas presentan la oportunidad de estudiar los efectos del flujo ...
-
(Universidad de Chile, 2013)Producto de la gran actividad minera en la región de Atacama, se qenero una gran cantidad de desechos de relaves que se vertieron aI curso deI Rio SaIado sin ningún tratamiento previo. Se estima que en eI trascurso de ...
-
(Wiley, 2017)Dendrite arbor growth, or dendritogenesis, is choreographed by a diverse set of cues, including the NMDA receptor (NMDAR) subunits NR2A and NR2B. While NR1NR2B receptors are predominantly expressed in immature neurons and ...
-
(2011)A set of regioisomeric pairs of tricyclic hydroquinones, analogues of antitumor 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one (1) and other derivatives, were synthesized and their regiochemistry and NMR spectra ...
-
(TAYLOR & FRANCIS, 2006)Measurements of H-1 and C-13 Nuclear Magnetic Resonance (NMR) for the nanocomposite materials formed by the intercalation of hexadecylamine (HAD) in metal oxides (TiO2, V2O5, CrO3 and MoO3), are reported. The H-1 NMR ...
-
(Springer, 2015)Fragile X syndrome (FXS) is the most common form of inherited intellectual disability. Previous studies have implicated mGlu5 in the pathogenesis of the disease, and many agents that target the underlying pathophysiology of ...
-
(Elsevier, 2012)Nitric oxide (NO), at physiological concentrations, is a tonic inhibitory modulator of carotid body (CB) chemosensory discharges. NO modulates the chemoreception process by several mechanisms, indirectly by modifying the ...
-
(Universite Laval, 1998)Following a short-term infestation by aphids, wheat seedlings show an increase in their concentration of hydroxamic acids (Hx), secondary metabolites conferring resistance against insects. The benefits for a wheat cultivar ...
-
(2007)Interfaces in two-dimensional systems exhibit unexpected complex dynamical behaviors. We present a robust effect of noise in two dimensional extended systems: the motion of a static front connecting a stripe pattern with ...
-
(Universidad de Chile, 2015)En esta tesis introducimos el concepto de estructlltr's covariantes {(d, "), (a, n), (a, d)} formadas por una C*-algebra "cy' separable, una acción torcida medible (a, a) de un gnrpo localmente compacto segundo-contable ...
-
(WILEY-BLACKWELL, 2016)AimWe used fossil and phylogenetic evidence to reconstruct climatic niche evolution in Nothofagus, a Gondwana genus distributed in tropical and temperate latitudes. To assess whether the modern distribution of the genus ...
-
(Elsevier, 2010)Hydrogen bond shortening and strengthening induced by confinement within fullerenes for a series of hydrogen bonded bihalides were studied. Significant increase in the electron localizability at the hydrogen bond region ...
