    Author(s): YM Barabash*, TV Serdenko, PP Knox and OYu Bondarenko
    Relevant: Is the study of the response of biological macromolecules to external stimuli. Often the reaction of macromolecules has an effect of structural self-regulation. In this case, their reaction is not only external infl uence, but also the spatial-temporal motions of the macromolecule. In this situation deserves the attention of electronic-conformational interac ...

    Potentiometric sensing platform for selective determination of Pregabalin in pharmaceutical formulations

    DOI Logo 10.17352/ojabc.000011

    Published On: September 05, 2019 | Pages: 049 - 056

    Author(s): Eman H El-Naby*
    Pregabalin is a structural analogue of, but functionally unrelated to, the naturally occurring neurotransmitter -aminobutyric acid (GABA) with potent analgesic, anticonvulsant and anxiolytic activity. The abuse potential of pregabalin is a well-documented with high risk of addiction that may be fatal with overdoses particularly, among opiate addicts and polydrug use ...

    Further remarks on the new criterion differentiating between Non-Redox and Redox Electrolytic Systems

    Published On: July 16, 2019 | Pages: 018 - 030

    Author(s): Anna M Michałowska-Kaczmarczyk, Tadeusz Michałowski*
    The new general criterion, distinguishing between non-redox and redox electrolytic systems, is based on the properties of the linear combination f12 = 2∙f(O) – f(H) of elemental balances: f1 = f(H) for Y1 = H, and f2 = f(O) for Y2 = O. The f12 is the primary form of the Generalized Electron Balance (f12 = prGEB), completing the set of balances needed to formulate a re ...

    General properties of the balance 2.f(O) – f(H) in electrolytic systems some detailed remarks on elemental versus core balances

    Published On: July 16, 2019 | Pages: 006 - 017

    Author(s): Anna M Michałowska-Kaczmarczyk, Tadeusz Michałowski*
    Any electrolytic system in aqueous media is described with use of charge balance, f0 = ChB, and K elemental or core balances, fk = f(Yk) (k = 1,…,K). The balances: f1 = f(H) and f2 = f(O) are the basis to formulate the linear combination f12 = 2.f2 – f1 = 2.f(O) – f(H). For a redox system with K – K* electronactive elements (players), f12 is linearly independent on ...
