(Elsevier, 2012-10-26)A new nitrooxoisoaporphine derivative was synthetized and characterized by cyclic voltammetry and electron spin resonance. Its aqueous solubility was improved by complexes formation with b-cyclodextrin, heptakis(2,6-di ...
-
(American Chemical Society, 2008-05-30)In a previous work, we studied the interaction of -amyloid fibrils (A ) with gold nanoparticles (AuNP) conjugated with the peptide CLPFFD-NH2. Here, we studied the effect of changing the residue sequence of the ...

(AMER CHEMICAL SOC, 2008-06)In a previous work, we studied the interaction of P-amyloid fibrils (A beta) with gold nanoparticles (AuNP) conjugated with the peptide CLPFFD-NH2. Here, we studied the effect of changing the residue sequence of the peptide ...
-
(Taylor and Francis Inc., 1998)An analytical chromatographic method for the determination of nimesulide in pharmaceutical forms has been developed. The method is based on high performance liquid chromatographic (HPLC) and electrochemical detection. ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1994-03)1. Kinetic and physico-chemical studies on human placental microsomal fraction confirmed that the ATPase and ADPase activities detected in this fraction correspond to the enzyme ATP-diphosphohydrolase or apyrase (EC 3.6.1.5). ...
-
(Wiley & Sons, 2016-06)Infection with human T-lymphotropic virus type 1/2 (HTLV-1/2) is a major health problem. HTLV-1/2 infection is endemic in Chile but representative donor prevalence data are lacking. Data on all blood donors in a large ...
-
(Wiley, 2020)Chronic cold stress affects ovarian morphology and impairs fertility in rats. It causes an ovarian polycystic ovary (PCOS)-like phenotype, which resembles PCOS in women. The mechanism of cold stress action involves increased ...
-
(Elsevier, 2013)Here we report the development of new drug nanocarriers – named hyaluronan nanocapsules – for the intracellular delivery of hydrophobic anticancer drugs. These nanocapsules are composed of a lipid core and a shell of ...
-
(ELSEVIER SCI LTD, 2004-05-11)Homogeneous transparent hybrid films consisting of chitosan (CHI), poly(monomethyl itaconate) (PMMI) and silica were obtained indicating the absence of microphase separation. These ternary hybrid materials are very interesting ...
-
(Oxford University Press, 2022)Aims Genetic and pharmacological inhibition of mitochondrial fission induced by acute myocardial ischaemia/reperfusion injury (IRI) has been shown to reduce myocardial infarct size. The clinically used anti-hypertensive ...
-
(ELSEVIER SCIENCE BV, 2005-09-14)The rhodium(l) complexes, cis-[Rh(CO)(2)(amine)(2)] (PF6) (amine = pyridine, 2-picoline, 3-picoline, 4-picoline, 3,5-lutidine or 2,6-lutidine) dissolved in methanol under carbon monoxide atmosphere are effective catalysts ...
-
(WILEY-V C H VERLAG GMBH, 2000-06-20)A large number of carboxylic groups were introduced onto chitosan by grafting with poly(acrylic acid) as an efficient way of modification. The reactions were carried out in a homogeneous aqueous phase by using potassium ...
-
(1975)A solvent and/or environmental effect has been introduced into the MO CNDO/2 calculation of a model hydrogen bonded system. Proton potential curves, potential energy, dipole moments, the polarizability component parallel ...
-
(1974)Second order perturbation theory (SOP) has been used to introduce electronic correlation effects on CNDP/2 calculated quantities like stabilization energy, proton potential curves, intermolecular dependence on distance and ...

Hydrogen-bonded supramolecular structures of three related 4-(5-nitro-2-furyl)-1,4-dihydropyridines (BLACKWELL, 2006-01)In ethyl 5-cyano-2,6-dimethyl-4-(5-nitro-2-furyl)-1,4-dihydropyridine-3-carboxylate, C15H15N3O5, the molecules are linked into chains by a single N-H (...) O hydrogen bond. The molecules in diethyl 2,6-dimethyl-4-(5-nitr ...
-
(Wiley-VCH, 2018-06-21)The hydrogenation reaction of multiple bonds that is mediated by geminal aminoborane-based frustrated Lewis pairs (FLPs) has been explored by means of density functional theory calculations. It was found that the release ...
-
(1997)The characteristic fatty acid composition of coconut oil provides mainly short- and medium- chain fatty acids when incorporated to the diet. These fatty acids have nutritional advantages because their metabolic disposition ...
-
(PERGAMON-ELSEVIER SCIENCE, 2002-06-01)The development of a new HPLC-UV diode array procedure applied to follow the hydrolytic degradation of two well-known 4-nitrophenyl-1,4-dihydropyridine derivatives, nitrendipine and nisoldipine is reported. Hydrolysis of ...
