-
(1988)Fluorescence techniques are used to study the effect of size on the properties of dioctadecyldimethylammonium chloride vesicles. The solubilization site and the deactivation rates of excited pyrene by bromide counterions ...
-
(1988)A study of the adsorption and thermodynamic functions of sulfur dioxide on Aerosil has been made, leading to some conclusions about the mobility of the SO2 molecule. The differential and integral enthalpies and entropies ...
-
(Informa Healthcare, 1989)The characteristics of the visible luminescence that follows the lipid peroxidative process were investigated either in the autoxidation of rat brain homogenates or in the azo-bis-arnidinopropane initiated lipid peroxidation ...
-
(1989)Nifurtimox disposition was evaluated in 7 healthy volunteers. Each subject received an oral dose of 15 mg/kg of nifurtimox and blood sample was obtained 11 h after the drug administration. We used an analytical method ...
-
(Royal Society of Chemistry, 2015)© The Royal Society of Chemistry 2015.In the present work we demonstrate from kinetic studies that under the experimental conditions proposed for the ORAC protocol, ORAC values do not correlate with the capacity of ...
-
(1988)Nifedipine, a calcium antagonist drug, produces a well-defined polarographic wave due to the four-electron, four-proton reduction of the nitro group. This peak is diffusion-controlled and shows a linear dependence on the ...
-
(Springer-Verlag, 1986)Fusion of a highly purified fraction of rat liver peroxisomal membranes to planar lipid bilayers incorporates large, cation-selective voltage-dependent pores. The PK/PCl ratio of these pores, estimated in KCl gradients, ...
-
(1988)An electrochemical study of the hallucinogen (±)-1-(2,5-dimethoxy-4- nitrophenyl)-2-aminopropane, which differs from similar compounds in that a hydrophilic nitro group replaces Hydrophobic substituants on the 4-position ...
-
(1986)Short or long term alloxan diabetes produced activation of oestrone and morphine glucuronidation and inhibition of p-nitrophenol glucuronidation in rat liver microsomes. Insulin treatment restored decreased glucuronyltransferase ...
-
(1986)Trazodone, a triazolopyridine derivative with antidepressant activity, is irreversibly oxidized in two steps in a large range of scan rates. The first peak shows a linear dependence on trazodone concentration. This behaviour ...
-
(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 ...
-
(1987)Soil samples collected in 1982 and 1983 from locations near an industrial park consisting of a Mo ore processing plant and a car battery manufacturing industry were analyzed for total and extractable Mo and Pb. Grass samples ...
-
(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 ...
