Performance comparison of nonlinear and linear regression algorithms coupled with different attribute selection methods for quantitative structure - retention relationships modelling in micellar liquid chromatography
(Elsevier, 2020)
In micellar liquid chromatography (MLC), the addition of a surfactant to the mobile phase in excess is accompanied by an alteration of its solubilising capacity and a change in the stationary phase’s properties. As an ...
Analysis of premature centromere division (PCD) of the chromosome 18 in peripheral blood lymphocytes in Alzheimer disease patients
(Elsevier Ireland Ltd, Clare, 2006)
Premature centromere division (PCD) of the chromosome 18 was analyzed by using fluorescent in situ hybridization (FISH) on interphase peripheral blood lymphocytes isolated from six sporadic Alzheimer disease (AD) patients ...

(Elsevier Science BV, Amsterdam, 2005)
The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively ...
Quantitative structure -retention relationship modeling of selected antipsychotics and their impurities in green liquid chromatography using cyclodextrin mobile phases
(Springer Heidelberg, Heidelberg, 2018)
Applying green chromatography methods is currently one of the challenges in liquid chromatography. Among different strategies, using cyclodextrin (CD) mobile phase modifiers was applied in this paper. CDs can form inclusion ...
Novel computational approaches to retention modeling in dual hydrophilic interactions/reversed phase chromatography
(Elsevier B.V., 2020)
The mixed-mode chromatographic behavior was estimated for imidazoline and serotonin receptor ligands, and their related compounds on dual hydrophilic/reversed phase stationary phase. The Box-Cox transfor- mation was used ...
Functionality and performance evaluation of directly compressible co-processed excipients based on dynamic compaction analysis and percolation theory
(Elsevier Science BV, Amsterdam, 2018)
In the present work functional properties of new, co-processed excipients, Pharmaburst (R) 500, Parteck (R) ODT, Ludiflash (R) and Disintequikn (TM) ODT, intended for direct compression of orally disintegrating tablets ...
Investigation of chromatographic conditions for the separation of cefuroxime axetil and its geometric isomer
(Elsevier Science BV, Amsterdam, 2004)
The optimal chromatographic conditions for the separation of the syn- and anti-geometric isomers of cefuroxime axetil applying RP-HPLC and micellar liquid chromatography (MLC) methods were investigated. The possibility to ...
Some therapeutic effects of herbal based ointment "Dermoplant G"on venous ulcers
(Georg Thieme Verlag Kg, Stuttgart, 2010)
Role of ovarian hormones in age-associated thymic involution revisited
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2010)
A commonly held view that ovarian hormones are causally involved in age-associated thymic involution has been recently challenged. In particular, their relevance in the progression of thymic involution has been disputed. ...
