Estimation of Lipophilicity of Some Polyoxygenated Steroids by the Means of Normal-Phase Thin-Layer Chromatography
(Taylor & Francis Inc, Philadelphia, 2015)
Unmodified silica gel in combination with two mobile phases, acetone-n-hexane and acetonitrile-dichloromethane, was used in order to evaluate the capability of normal-phase (NP) chromatography on bare silica gel in estimation ...
Nonlinear frequency response analysis of forced periodic operation of non-isothermal CSTR with simultaneous modulation of inlet concentration and inlet temperature
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The nonlinear frequency response (NFR) method is applied for evaluation of possible improvement through simultaneous periodic modulation of two inputs of a non-isothermal continuously stirred tank reactor (CSTR) in which ...
Synthesis and biological activity of amino acid derivatives of avarone and its model compound
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
A series of eighteen derivatives of marine sesquiterpene quinone avarone and its model system tert-butylquinone with amino acids has been synthesized by nucleophilic addition of amino acids to the quinones. In vitro cytotoxic ...
Chemo-protective and regenerative effects of diarylheptanoids from the bark of black alder (Alnus glutinosa) in human normal keratinocytes
(Elsevier, 2015)
Medicinal plants are recognized from ancient times as a source of diverse therapeutic agents and many of them are used as dietary supplements. Comprehensive approaches are needed that would identify bioactive components ...
Reactions of superoxide dismutases with HS-/H2S and superoxide radical anion: An in vitro EPR study
(Academic Press Inc Elsevier Science, San Diego, 2015)
Interactions of hydrogen sulfide (HS-/H2S), a reducing signaling species, with superoxide dimutases (SOD) are poorly understood. We applied low-T EPR spectroscopy to examine the effects of HS-/H2S and superoxide radical ...
Strong in Vitro Cytotoxic Potential of New Ruthenium-Cymene Complexes
(American Chemical Society (ACS), 2015)
Two p-cymenerutheniumchlorido complexes with thiourea derivative of 7-chloroquinoline (C1) and pyridine-3-imidazole (C2) were synthesized starting from [(eta(6)-p-cymene)RuCl2](2) and corresponding ligands. The structures ...
Analogy between momentum and heat transfer in liquid-solid fluidized beds
(Elsevier, 2015)
Wall-to-bed heat transfer in particulate fluidized beds of spherical particles was studied. Experiments were performed using spherical glass particles of 0.80-2.98 mm in diameter with water in a 25.4 mm I.D. copper tube ...
Visible light absorption of surface modified TiO2 powders with bidentate benzene derivatives
(Elsevier, 2015)
TiO2 powders with different specific surface area were prepared using reproducible, sol gel synthetic route and their ability to form hybrids with catechol and 5-amino salicylic acid was compared with the commercially ...
Reliable simultaneous zymographic method of characterization of cellulolytic enzymes from fungal cellulase complex
(Wiley-Blackwell, Hoboken, 2015)
A method for zymographic detection of specific cellulases in a complex (endocellulase, exocellulase, and cellobiase) from crude fermentation extracts, after a single electrophoretic separation, is described in this paper. ...
Synthesis, crystal structures, and antimicrobial activity of square-planar chloride and isocyanate Ni(II) complexes with the condensation product of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent
(Taylor & Francis Ltd, Abingdon, 2015)
Square-planar isocyanate and chloride Ni(II) complexes with tridentate PNO condensation product of 2-(diphenylphosphino)benzaldehyde and Girard's T reagent have been synthesized and their crystal structures were determined. ...
