Determination of ascorbic acid in pharmaceutical dosage forms and urine by means of an oscillatory reaction system using the pulse perturbation technique
(Springer Heidelberg, Heidelberg, 2007)
A simple and reliable method for the determination of ascorbic acid (AA) is proposed and validated. It is based on potentiometric monitoring of the concentration perturbations of an oscillatory reaction system in a stable ...

The role of nitric oxide in paraquat-induced oxidative stress in rat striatum
(Inst Agricultural Medicine, Lublin, 2007)
The role of nitric oxide (NO) in paraquat (PQ)-induced neurotoxicity is still not fully understood. In this study we used N-G-nitro-L-arginine methyl ester (L-NAME), a non-selective nitric oxide synthase (NOS) inhibitor, ...
Spectrophotometric investigation of the uranyl-phenylephrine system / Spektrofotometrijsko ispitivanje uranil-fenilefrin sistema
(Srpsko hemijsko društvo, Beograd, 2007)
Using spectrophotometric methods and pH-metric measurements, it was found that the uranyl ion and phenylephrine form a 1:2 complex in the pH region 2.50-4.25 with two absorption maxima at 314.2 nm and 340.6 nm. The ...
Synchronization of noisy delayed feedback systems with delayed coupling
(American Physical Soc, College Pk, 2007)
Synchronization of delayed coupled and stochastically perturbed systems with delayed nonlinear feedback is studied, using as an example circular chains of three and four delayed coupled Ikeda oscillators. It is proved that ...
Interaction between food and drugs for treatment of depress and anxiety disorders / Interakcije hrane i lekova za lečenje depresije i anksioznih poremećaja
(Savez farmaceutskih udruženja Srbije, Beograd, 2007)
Interactions between food drugs for depression and anxiety are very complex and not yet completely investigated. Besides direct interactions that can enhance, decrease or modify the medication action, food can effect ...
Experimental design in chromatographic analysis of pramipexole and its impurities
(Slovensko Kemijsko Drustvo, Ljubljana, 2007)
Pramipexole is a dopamine D2-agonist/antiparkinsonian agent in which BI-II 546 CL, BI-II 751 xx and 2-amino benzothiazole are commonly found as impurities. Due to the lack of analytical data on pramipexole and its related ...
A simple and sensitive TLC method for determination of clopidogrel and its impurity SR 26334 in pharmaceutical products
(Univ Silesia, Inst Chemistry, Katowice, 2007)
A simple, conventional TLC method has been established for separation of clopidogrel and its hydrolytic product SR 26334, the main impurity in clopidogrel. Use of aluminium. foil-backed silica gel 60F(254) plates with ...
Effect of n-3 fatty acids on nutritional status and inflammatory markers in haemodialysis patients
(Wiley, Hoboken, 2007)
Aims: Nutrition as an aetiological factor participates a great deal in premature atherosclerosis in haemodialysis (HD) patients. The basic mechanisms of end-stage renal disease and premature atherosclerosis are connected ...
An alkylpolyglucoside surfactant as a prospective pharmaceutical excipient for topical formulations: The influence of oil polarity on the colloidal structure and hydrocortisone in vitro/in vivo permeation
(Elsevier Science BV, Amsterdam, 2007)
There is a growing need for research into new skin- and environment-friendly surfactants. This paper focuses on a natural surfactant of an alkylpolyglucoside type, which can form both thermotropic and lyotropic liquid-crystalline ...
