(1986)An HPLC method described by Mancllla and Gll [Analytical Letters 17,(B9),1984,873-886] has been applied to study the sex dependent expression of several rat liver testosterone hydroxylases. A sample clean up procedure has ...
-
(1986)The absorption and disposition kinetics of lithium carbonate administered to eight healthy volunteers in two dosage forms were studied. A conventional immediate release tablet and a controlled release preparation, developed ...
-
(1988)A mathematical treatment is presented that allows the experimental determination of fluoride concentrations at the ng ml<sup>-1</sup> level with good precision. The proposed method is able to determine blank ...
-
(1988)The apparent permeation rate constants and amount of ranitidine transferred in 1 h were measured through everted rat intestine using a perfusion apparatus. The effects of pH and 5% or 10% ethanol on the apparent permeation ...
-
(Elsevier, 1997)Conformational analysis of famotidine (FAMO) and some analogues have been performed using AM1 calculations. In addition, conformational analysis were done on the 2-guanidinylthiazole moiety in order to see the effect of ...
-
(1985)Abstract— The quenching rate of triplet benzophenone in water and/or water mixtures has been determined employing vitamin C, vitamin E, cystine, cysteine, reduced and oxidized glutathione, methionine and DL‐penicillamine. ...
-
Polarographic behaviour and determination of nitrofurantoin, chloramphenicol and related compounds (1984)The polarographic behaviour of nitrofurantoin and chloramphenicol have been studied in pyridine - formic acid buffer and tetramethylammonium chloride solution at pH 4.3. The E<inf>1/2</inf> versus pH and iym ...
-
(1986)Human fetal hemoglobin assayed in a peroxidizing system shows an increased prooxidative effect when compared to human adult hemoglobin. This effect is related only to the oxyhemoglobin form since both fetal and adult ...
-
(1986)The diposition of gentamicin was studied in five children with nephrotic syndrome and five control children to observe the effect of nephrotic syndrome on the distribution and elimination of the antibiotic. After a single ...
-
(1984)Adverse drug reactions (ADRs) may be more frequent in patients who present some diseases. By means of an intensive prospective drug surveillance work, 492 patients with heart diseases, hospitalized at the Department of ...
-
(1985)1. 1. Liver microsomes from alloxan diabetic rats displayed decreased activity to hydroxylate testosterone only at the 2-α and 6-β positions. 2. 2. Diabetic insulin-treated rats showed higher hydroxylase activities than ...
-
(Birkhäuser-Verlag, 1986)We have observed a differential effect of silybin dihemisuccinate on rat liver microsonal oxygen consumption and on lipid peroxidation induced by NADPH-Fe2+-ADP and t-butyl hydroperoxide. These results are ascribed to the ...

(1996)(2'E, 6'E, 10'E, 14'E)-2-(8',9'-dione-3', 7', 11', 15'-tetramethylhexadeca-2', 6', 10', 14'-tetraenyl)-6-Methyl-1,4-benzoquinone, (2'E, 6'E, 10'E, 14'E)-2-(8'-one, 15'-formyl-3', 7', 11', trimethylhexadeca-2', 6', 10', ...
-
(Kluwer Academic Publishers, 1983)Based on a similarity ring constructed from a substitution probability matrix, we have analyzed the conservation of some amino acid properties in the evolution of proteins. Refractive index and bulkiness are highly conserved, ...
-
(1982)The electroactivity of a degradation product from penicillin V is described.This electroactive product is formed by acidic hydrolysis at pH 4.0 and heating at 90QC for 60 minutes. This derivative has not been identified, ...
-
Cyclic voltammetry and digital simulation of the electroreduction of ortho- and meta-nitro aryl ... (1999)Cyclic voltammetry (CV) and digital simulation methods are utilized to elucidate the mechanism of electrochemical reduction of a series of nitro aryl 1,4-dihydropyridines in protic (aqueous) and mixed media. The experimental ...
-
(1984)The isolation and identification of a cathodic degradation product from cephradine after acidic hydrolysis in presence of 1 % formaldehyde is reported. Also, the electroacti vity of an anodic degradation product is described. ...
-
(1983)Kainate (0.62-5 mM) was found to increase the initial rate of influx of 45Ca and of 22Na into the non-inulin space of rat thin brain cortex slices incubated in vitro, and to shorten the equilibration time for both these ...
-
(1983)As part of study of Chagasic cardiopathy in Chile we report a follow-up study of 100 cardiopathic patients from two endemic areas who had been diagnosed 4 years earlier during an epidemiological and clinical survey. The ...
-
(2012)A new withanolid amine was isolated from Dunalia spinosa (Solanaceae). Its relative stereochemistry was determined using FT-IR, 1H and 13C NMR spectroscopies and high resolution mass spectrometry. Nicotine was also isolated; ...
