Abstract: A simple and rapid liquid chromatography-tandem mass spectrometric (LC-MS/MS)assay method has been developed and fully validated for simultaneous quantification of pioglitazone and candesartan in human plasma.Irbesartan was used as an internal standard.The analytes were extracted from human plasma s...
Abstract: A new modification method for glass slides was developed and applied to make ThinPrep Pap smears,in order to increase the adhesion ability of cervical exfoliative cells.3-glycidyloxypropyl trimethoxysilane (GOPS) was coated on the glass slides firstly on the slides,then poly-L-lysine (PLL)was covale...
Abstract: A simple,sensitive,and specific liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the quantification of desloratadine (DL) in human plasma using desloratadine-d5 (DLD5) as an internal standard (IS).Chromatographic separation was performed using an Xbridge C18 column ...
Abstract: The purpose of this work was to introduce a new concept of coated pellets containing chitosan microspheres loaded with didadosine for oral administration,aiming at reducing the frequency of administration and improving the bioavailability by a suitable release profile.Chitosan microspheres were prod...
Abstract: Anodic behavior of aripiprazole (ARP) was studied using electrochemical methods.Charge transfer,diffusion and surface coverage coefficients of adsorbed molecules and the number of electrons transferred in electrode mechanisms were calculated for quasi-reversible and adsorption-controlled electrochem...
Abstract: A rapid,sensitive and simple spectrofluorimetric method was developed for the estimation of atorvastatin.In this method,the native fluorescence characteristics of atorvastatin have been studied in both acidic and basic media.High sensitivity was obtained with 5% acetic acid at 389 nm using 276 nm fo...
Abstract: A rapid and sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS)assay method has been developed and fully validated for the simultaneous quantification of pravastatin and aspirin in human plasma.Furosemide was used as an internal standard.Analytes and the internal standard were extra...
Abstract: Plasma quinolone concentrations are not routinely measured in clinical practice.However,in order to optimize quinolone treatment,monitoring of plasma concentrations could sometimes be useful particularly in critically ill patients.In this study,anti-sparfloxacin antibody was obtained by immunizing r...
Abstract: The stereoselective hydrolysis of esmolol in whole blood and in its separated components from rat,rabbit and human was investigated.Blood esterase activities were variable in different species in the order of rat > rabbit > human.Rat plasma showed the high esterase activity and had no stereose...
Abstract: A stability-indicating liquid chromatographic method has been developed and validated for the determination of Diltiazem Hydrochloride (DTZ) together with its six related substances (Diltiazem sulphoxide,Imp-A,Imp-B,Imp-D,Imp-E,and Imp-F) in a laboratory mixture as well as in a novel tablet formulat...
Abstract: Oleanolic acid (OA) and ursolic acid (UA) are isomeric triterpenic acids and only one methyl's position is different between them.OA and UA always exist in the same plant,so it is difficult to separate them when determining contents by RP-HPLC.In this study,a very simple mobile phase for HPLC was de...
