Determination of pKa values of some antipsychotic drugs by HPLC-correlations with the kamlet and taft solvatochromic parameters and HPLC analysis in dosage forms
(2013)
In this study, ionization constant (pKa) values were determined by using the dependence of the retention factor on the pH of the mobile phase for four ionizable drugs, namely, risperidone (RI), clozapine (CL), olanzapine ...
Fully validated simultaneous determination of bisoprolol fumarate and hydrochlorothiazide in their dosage forms using different voltammetric, chromatographic, and spectrophotometric analytical methods
(2013)
Voltammetric, chromatographic, and spectrophotometric methods were developed for the simultaneous determination of bisoprolol fumarate (BIS) and hydrochlorothiazide (HCZ). Differential pulse and square wave voltammetry ...
A validated stability-indicating RP-LC method for the simultaneous determination of amlodipine and perindopril in tablet dosage form and their stress degradation behavior under ICH-recommended stress conditions
(2013)
A stability-indicating RP-LC assay method was developed for the simultaneous determination of the cardiovascular drugs amlodipine and perindopril in the presence of degradation products generated from forced decomposition ...
N-O tethered carbenoid cyclopropanation facilitates the synthesis of a functionalized cyclopropyl-fused pyrrolidine
(2013)
We report a facile approach to a cyclopropyl-fused pyrrolidine, which contains four stereogenic centers, by employing the N-O tethered carbenoid methodology. The synthesis was facilitated by the development of a direct ...

(Editions de l'Academie Republique Populaire, 2013)
In this research, sensitive, rapid, different electrochemical methods were developed for the determination of anticancer drug epirubicin. The aim of the study was to fully validated determination of epirubicin in ...
Validated electroanalytical and RP-LC assay of ertapenem in its pharmaceutical dosage form
(Editions de l'Academie Republique Populaire, 2013)
Ertapenem is a member of carbapenem group beta-lactam antibiotics. The electrochemical behavior of ertapenem at the surface on a boron-doped diamond electrode is described. It is investigated and determined using cyclic, ...
Inhibition effect of berberine on the corrosion of copper in acidic medium
(Editions de l'Academie Republique Populaire, 2013)
Inhibition of copper corrosion by berberine in 0.5 M HCl was investigated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The inhibition efficiency of berberine was studied for ...
Heart-type fatty acid-binding protein as a potential biomarker of acute carbon monoxide poisoning
(2013)
Background The aim of this study was to investigate the role of serum heart-type fatty acid-binding protein (H-FABP) in the evaluation of patients with carbon monoxide (CO) poisoning. Methods Forty patients with acute CO ...
Efficient removal of acidic dye using low-cost biocomposite beads
(2013)
The objective of this study is to prepare and characterize chitosan/zeolite biocomposite beads and utilize them as adsorbent for removal of anionic dye, Acid Black 194 (AB194). Characterization studies of biocomposite beads ...
Efficient and broadband guided wave one-way mode-order conversion with theoretical and numerical analysis
(Optical Society of American (OSA), 2013)
In this article, an efficient method of asymmetric conversion of guided modes is investigated. From a basic excitation consisting of (mainly) the lowest-order mode of the input multimode strip waveguide, we achieve a ...
