(1997)We studied the effects of sodium nitroprusside, a nitric oxide donor, on the chemosensory responses to cyanide and nicotine in the cat carotid body. In situ, sodium nitroprusside infusion reduced the cyanide-evoked responses ...
-
(Springer-Verlag, 1979)In order to determine whether the uptake of gastrin and secretin is limited to specific organ systems (especially the kidney) or whether loss is a nonspecific occurrence across all capillary beds, we have measured the ...

(BLACKWELL PUBLISHING LTD, 2004-10-21)In a search for cataclysmic variables in the Calan-Tololo Survey, we have detected 21 systems, 16 of them previously unknown. In this paper we present detailed time-series photometry for those six confirmed cataclysmic ...
-
(WILEY-BLACKWELL, 2010-06-11)In this second paper on cataclysmic variables detected in the Cal´an–Tololo Survey we present time-resolved spectroscopy for the remaining eight systems without a measured orbital period. We derive orbital periods for ...

(EDP SCIENCES S A, 2006-11)Aims. The present paper describes the first results of an observational program intended to refine and extend the existing v sin i measurements of metal-poor stars, with an emphasis on field evolved stars. Methods. The ...
-
(IOP Publishing, 2015)We present a catalog of visual-like H-band morphologies of similar to 50.000 galaxies (H-f160w < 24.5) in the 5 CANDELS fields (GOODS-N, GOODS-S, UDS, EGS, and COSMOS). Morphologies are estimated using Convolutional Neural ...

(1981)The general acid catalysed hydrolysis and the intramolecular nucleophilic anionic cyclization of acyloximes operate concurrently in water at pH 7-9. Hydrolysis is inhibited by cationic micelles; changing the length of the ...
-
(Elsevier S.A., 2019)A new series of novel complexes of type cis-[Ru(CO)2Cl2(L)2], L = 2-phenyl-1,8-naphthyridine, 2-(4′-nitrophenyl)-1,8-naphthyridine, 2-(4′-bromophenyl)-1,8-naphthyridine, 2-(4′-methylphenyl)-1,8-naphthyridine, 2-(3′-metho ...
-
(Royal Society of Chemistry, 2019)The synthesis and characterization of a new ruthenium(ii) complex containing a hemilabile P^N-ligand are reported. The catalytic activity of this complex was evaluated in the hydrogen transfer reaction of acetophenone and ...
-
(MDPI, 2021)Amyloids are supramolecular assemblies composed of polypeptides stabilized by an intermolecular beta-sheet core. These misfolded conformations have been traditionally associated with pathological conditions such as Alzheimer's ...
-
(Elsevier, 2012)In some archaea, glucose degradation proceeds through a modified version of the Embden-Meyerhof pathway where glucose and fructose-6-P phosphorylation is carried out by kinases that use ADP as the phosphoryl donor. Unlike ...
-
(Springer, 2013)Pyridoxal 50-phosphate is the active form of vitamin B6 and its deficiency is directly related with several human disorders, which make human pyridoxal kinase (hPLK) an important pharmacologic target. In spite of this, ...
-
(Royal Soc Chemistry, 2016)The need of deeper insights regarding the inner working of catalysts represents a current challenge in the search of new ways to tune their activities towards new chemical transformations. Within this field, metallophtha ...
-
(Elsevier, 2015)Autoantibodies from autistic spectrum disorder (ASD) patients react with multiple proteins expressed in the brain. One such autoantibody targets myelin basic protein (MBP). ASD patients have autoantibodies to MBP of both ...
