(ELSEVIER SCI LTD, THE BOULEVARD, 2001-07-12)Sucrose forms a dicationic complex with cobalt(III)bis(phenanthroline) which can be isolated as the sparingly water-soluble triiodide salt or the water-soluble chloride. The circular dichroism (CD) spectrum demonstrates ...
-
(HUMANA PRESS INC, 2001-08)Morphological studies of granular neurons of the hippocampus have shown that adrenalectomy (ADX) induces the cell death of granular neurons, an effect prevented by corticosterone replacement. We addressed the hypothesis ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2001-08)The ESR spectra of radicals obtained by electrolytic reduction of 4,4-dimethylanthracene- 1,9,10 (4H)-trione (1) and the regioisomeric quinones 8-acetyloxymethyl-4,4,5-trimethyl- (2), and 5-acetyloxy-methyl-4,4,8-trimeth ...
-
(PERGAMON-ELSEVIER SCIENCE, 2001-08-31)This paper reports a comprehensive study by tast polarography, d.p.p., and cyclic voltammetry on the electrochemical reduction in different electrolytic media of ortho- and meta-nitrotoluene derivatives. Controlled potential ...
-
(AMER CHEMICAL SOC, 2001-09)Densities and viscosities for 1,4-dioxane with 1-propanol and 2-propanol mixtures have been measured as a function of mole fraction at atmospheric pressure at (25, 30, 35, and 40) degreesC. The calculated excess volumes ...
-
(ACADEMIC PRESS INC, 2001-09)Chagas' disease constitutes a therapeutic challenge because presently available drugs have wide toxicity to the host and are generally ineffective in the chronic stages of the disease. A series of oxazolo(thiazolo)pyridene ...
-
(LIPPINCOTT WILLIAMS & WILKINS, 2001-09)Angiotensin I is a substrate for both ACE and for neutral endopeptidase 24.11 (NEP). We hypothesized that high ACE expression is related to low NEP activity. Accordingly, circulating and tissue NEP and ACE activities were ...
-
(AOAC INTERNATIONAL, 2001-09)The aim of the work described in this paper was to provide a fast, easy, inexpensive, precise, and accurate method for the determination of melatonine in solid pharmaceutical dosage forms. The developed method is based on ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2001-09)The electro-oxidation of methanol at Pt-Ir and Pt deposits, and at Pt, Ir, and Pt-Ir wires in sulfuric acid solution was studied by cyclic voltammetry (CV), and in the case of Pt-Ir and Pt electrodeposits, also with the ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2001-09)Activation parameters for the rotation around the methylene-nitrogen single bond found in a series of four 2,2'-disubstituted N-acetyl-N-phenylbenzylamines, dissolved in DMSO-d(6), were measured employing the temperature ...
-
(ELSEVIER SCIENCE, 2001-09-21)Megazol (2-amino-5-(1-methyl-5-nitro-2-imdazolyl)-1,3,4-thiadiazol, CAS 19622-55-0) and related nitroimidazole compounds are being tested as antichagasic drugs. Little is known on the mode of action of megazol. However, ...
-
(SPRINGER-VERLAG, 2001-10)The possibility of a total substitution of ega proteins in yellow cakes by vegetable proteins isolated from white lupine seeds was studied. The effects of several components on hardness, moisture content, volume, and shape ...
-
(ELECTROCHEMICAL SOC INC, 2001-10)We have synthesized three nitrocompounds in order to mimic the model structure of some relevant drugs such as nifedipine, nitrendipine, nisoldipine, nimodipine, and related ones, in order to investigate the effect of ...
-
(CURRENT SCIENCE ASSN, 2001-10-25)Lignin, the most abundant renewable source of aromatic carbon on earth, consists in a highly irregular three-dimensional biopolymer of oxygenated phenylpropanoid units. In natural environments, lignin is only degraded ...
-
(AMER CHEMICAL SOC, 2001-10-30)Deuterium quadrupole splittings from two series of optical isomers, L- and D-N-acyl-l-phenyl-d(5)-2-aminopropane, with linear acyl chains ranging from I to 10 carbon atoms, were measured using H-2 NMR spectroscopy. Both ...
-
(ELSEVIER SCI IRELAND LTD, 2001-11)The antiinflammatory and antipyretic activities of the petroleum ether extract (PEE), dichloromethane extract (DME) and methanol extract (ME1) of the aerial part of Psoralea glandulosa L. (Papilionaceae) were studied. The ...
-
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2001-11)We investigated the effects of alpha1-antitrypsine Portland variant (alpha1-PDX) and decanoylRVKRchloromethylketone (decRVKRcmk) on HIV-2(ROD) replication in the Jurkat lymphoblastoid cell line. To this end, cells were ...
-
