Engineering of a bacterial tyrosinase for improved catalytic efficiency towards D-tyrosine using random and site directed mutagenesis approaches
(Wiley-Blackwell, Hoboken, 2013)
The tyrosinase gene from Ralstonia solanacearum (GenBank NP518458) was subjected to random mutagenesis resulting in tyrosinase variants (RVC10 and RV145) with up to 3.2-fold improvement in kcat, 5.2-fold lower Km and 16-fold ...
The use of graphene nanoribbons as efficient electrochemical sensing material for nitrite determination
(Elsevier Science Bv, Amsterdam, 2016)
In this work new designed, highly sensitive electrochemical method is developed for the determination of nitrites in tap water using glassy carbon electrode modified with graphene nanoribbons (GNs/GCE). Graphene nanoribbons ...
The effect of polyphosphate kinase gene deletion on polyhydroxyalkanoate accumulation and carbon metabolism in Pseudomonas putida KT2440
(Wiley-Blackwell, Hoboken, 2013)
The primary enzyme involved in polyphosphate (polyP) synthesis, polyP kinase (ppk), has been deleted in Pseudomonas putidaKT2440. This has resulted in a threefold to sixfold reduction in polyhydroxyalkanoate (PHA) accumulation ...
Advanced electrochemical platform for determination of cytostatic drug flutamide in various matrices using a boron-doped diamond electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
An innovative, rapid and simple electrochemical approach for the reliable quantification of cytostatic drug flutamide (FLU) in various matrices is herein proposed. This platform involves coupling of differential pulse (DPV) ...
Mercury-free and modification-free electroanalytical approach towards bromazepam and alprazolam sensing: A facile and efficient assay for their quantification in pharmaceuticals using boron-doped diamond electrodes
(Elsevier Science Sa, Lausanne, 2017)
The boron-doped diamond electrodes (BDDEs) with different dopant levels were applied as advanced, mercury-free and modification-free electroanalytical platforms for simple and reliable quantification of benzodiazepines, ...
Mechanisms of redox interactions of bilirubin with copper and the effects of penicillamine
(Elsevier Ireland Ltd, Clare, 2017)
Toxic effects of unconjugated bilirubin (BR) in neonatal hyperbilirubinemia have been related to redox and/or coordinate interactions with Cu2+. However, the development and mechanisms of such interactions at physiological ...
Dynamics of the Water Molecules at the Intrinsic Liquid Surface As Seen from Molecular Dynamics Simulation and Identification of Truly Interfacial Molecules Analysis
(Amer Chemical Soc, Washington, 2016)
Dynamic properties at the liquid-vapor interface of water are investigated at 298 K on the basis of molecular dynamics simulations and intrinsic surface analysis. The mean surface residence time and diffusion coefficient ...
Simple One-Pot Synthesis of Fully Biobased Unsaturated Polyester Resins Based on Itaconic Acid
(Amer Chemical Soc, Washington, 2017)
For the preparation of fully biobased unsaturated polyester resins (UPRs), the replacement of styrene with alternate nonpetroleum-based monomers turned out to be one of the most challenging tasks. Its complexity lies in ...
High-performance thin-layer chromatography combined with pattern recognition techniques as tool to distinguish thickening agents
(Elsevier Sci Ltd, Oxford, 2017)
A simple, rapid, and accurate high-performance thin-layer chromatography (HPTLC) method was applied in combination with powerful pattern recognition techniques for differentiating thickening agents, which are mainly based ...
Profiling and classification of French propolis by combined multivariate data analysis of planar chromatograms and scanning direct analysis in real time mass spectra
(Elsevier Science Bv, Amsterdam, 2016)
Quality control of propolis is challenging, as it is a complex natural mixture of compounds, and thus, very difficult to analyze and standardize. Shown on the example of 30 French propolis samples, a strategy for an improved ...
