(Marcel Dekker Inc., 2000)A second derivative spectrophotometric method has been developed for the determination of palladium and platinum in mixtures. The method is based on the formation of the platinum and palladium complexes with 3-(2- ...
-
(2000)Three new genes (Cs-mnp2A, Cs-mnp2B and Cs-mnp3) coding for manganese- dependent peroxidase (MnP) have been identified in the white-rot basidiomycete Ceriporiopsis subvermispora. The mature proteins contain 366 (MnP2A and ...
-
(2000)Tacrine, 9-amino-1,2,3,4-tetrahydroacridine, an antialzheimer's disease agent was electrochemically studied and a polarographic method for its quantitative determination in pharmaceuticals was developed. Tacrine was ...
-
(1999)The regiosomeric quinones 5-acetyloxymethyl-4,4,8-trimethyl-(5) and 8-acetyloxymethyl-4,4,5-trimethylanthracene-1,9,10(4H)-trione (6) were synthesized and their regiochemistry was assigned on the basis of the unambiguous ...
-
(1999)St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2'- ...
-
(1999)A comparative study of fish species identification was accomplished using three different electrophoretic techniques. Sarcoplasmic proteins were extracted from three related fish species and subjected to gel isoelectrofocusing ...

Fat deterioration in deep fat frying of «french fries» potatoes at restaurant and food shop sector (Instituto de la Grasa, 1999)The objective of this work was to know the deterioration of fats employed in deep frying of «french fries» potatoes at restaurant and food shop sector in Santiago (Chile), before the recent Chilean legislation became ...
-
(1992)1. 1. In the present work the analgesic effect of benzodiazepines (BZD) and flumazenil (FLU) using the writhing test in mice was studied. 2. 2. Intracerebroventricular administration of BZD exhibited a dose-dependent ...
-
(2000)The reaction of CpFe(dppe)I (Cp, cyclopentadienyl; dppe, Ph2P(CH2)(2)PPh2) with biologically active RSH molecules (L-cysteine hydrochloride, dithiothereitol and 2-mercaptoethanol) in the presence of NH4PF6 and in methanol ...
-
(1999)The aim of this study was to estimate the prevalence of the different alleles of the angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and associated plasma ACE activity, as well as cardiac ...
-
(1999)To confirm the geographic and ethnic segregation of HTLV-I and HTLV-II carriers in native populations in South America, we have conducted a seroepidemiological study of native populations in South America, including HTLV-I ...
-
(1999)A direct and simple first derivative spectrophotometric method has been developed for the simultaneous determination of clidinium bromide and chlordiazepoxide in pharmaceutical formulations. Acetonitrile was used as solvent ...
-
(1999)1. Fenoldopam mesylate, a benzazepine derivative, is a D1 receptor agonist that lowers blood pressure through vasodilation of renal, mesenteric, coronary and cerebral vascular beds. 2. Experiments were performed in rats, ...
-
(1999)Several lines of evidence suggest that a defective protein folding is a central event in both Alzheimer's and prion disease. Although the two disorders are very different clinically, neuropathologically, and biochemically, ...
-
(1992)In this work the microsomal lauric acid ω-hydroxylation, fatty acid peroxisomal β-oxidation, and the levels of cytochrome P-450 IVAI were studied in liver tissue from starved rats. Starvation increased the peroxisomal ...
-
(Elsevier Ltd, 1998)Cobalt phthalocyanine (CoPc) and cobalt naphthalocyanine (CoNPc) exhibit different redox and electronic properties. Redox processes on CoPc are more reversible than on CoNPc. The pH dependence of those processes is also ...

(1998)Lipid peroxidation in rat brain slices was induced by Fe+3/ascorbate.Brain lipid peroxidation, as measured by malondialdehyde formation, was inhibited by all the tested nitro aryl 1,4-dihydropyridine derivatives over a ...
-
(Academic Press Inc., 1998)There is evidence that insulin-like growth factor-1 (IGF-1) plays a role in the development of left ventricular hypertrophy, but it is uncertain whether cardiac IGP-1 changes before or after hypertension is established, ...
