Pattern recognition methods and multivariate image analysis in HPTLC fingerprinting of propolis extracts
(Wiley-Blackwell, Hoboken, 2014)
High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting and classification of 52 propolis samples collected from Serbia and one sample ...
Biotransformation of 4-halophenols to 4-halocatechols using Escherichia coli expressing 4-hydroxyphenylacetate 3-hydroxylase
(Springer, New York, 2011)
Escherichia coli cells, expressing 4-hydroxyphenylacetate 3-hydroxylase, fully transformed 4-halogenated phenols to their equivalent catechols as single products in shaken flasks. 4-Fluorophenol was transformed at a rate ...
Coordination and redox interactions of β-lactam antibiotics with Cu2+ in physiological settings and the impact on antibacterial activity
(Elsevier, 2018)
An increase in the copper pool in body fluids has been related to a number of pathological conditions, including infections. Copper ions may affect antibiotics via the formation of coordination bonds and/or redox reactions. ...
Isolation and characterization of four novel Gram-positive bacteria associated with the rhizosphere of two endemorelict plants capable of degrading a broad range of aromatic substrates
(Springer, New York, 2011)
Four new Gram-positive, phenol-degrading strains were isolated from the rhizospheres of endemorelict plants Ramonda serbica and Ramonda nathaliae known to exude high amounts of phenolics in the soil. Isolates were designated ...
Experimental and theoretical investigations of the self-association of oxaliplatin
(Royal Soc Chemistry, Cambridge, 2014)
Self-aggregation in water of anti-cancer agents such as oxaliplatin (1) or its palladium-containing parent (2) is suspected to be the main reason for the exceptional resistance of concentrated infusions of these complexes ...
New electrochemical method for the determination of beta-carboline alkaloids, harmalol and harmine, in human urine samples and in Banisteriopsis caapi
(Elsevier Science Bv, Amsterdam, 2015)
In this paper a new electrochemical method for determination of the beta-carboline alkaloids, harmalol and harmine, using differential pulse voltammetry is presented. Experimental parameters such as pH, scan rate, pulse ...
Employment of colorimetric enzyme assay for monitoring expression and solubility of GST fusion proteins targeted to inclusion bodies
(Elsevier Science Bv, Amsterdam, 2013)
High levels of recombinant protein expression can lead to the formation of insoluble inclusion bodies. These complex aggregates are commonly solubilized in strong denaturants, such as 6-8 M urea, although, if possible, ...
Newly designed hemagglutinin-Der p 2 chimera is a potential candidate for allergen specific immunotherapy
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Aim To investigate the immunomodulatory potential of a chimera composed of the receptor-binding domain of hemagglutinin 1 (H1s) from Influenza virus and Der p 2 (D2) allergen for allergen-specific immunotherapy of house-dust ...
Methane Activations by Titanium Neopentylidene Complexes: Electronic Resilience and Steric Control
(ACS Publications, 2017)
The titanium neopentylidene complex (PNP)Ti=CHtBu(CH2 tBu) (PNP = N[2-PiPr2-4-methylphenyl]2-) is capable of activating both sp2 and sp3 C-H bonds under mild conditions. In addition to methane C-H activation, competition ...
Lipophilicity Assessment of Ruthenium(II)-Arene Complexes by the Means of Reversed-Phase Thin-Layer Chromatography and DFT Calculations
(Hindawi Publishing Corporation, New York, 2014)
The lipophilicity of ten ruthenium(II)-arene complexes was assessed by reversed-phase thin-layer chromatography (RP-TLC) on octadecyl silica stationary phase. The binary solvent systems composed of water and acetonitrile ...
