Determination of pyridoxine (vitamin B-6) in pharmaceuticals and urine samples using unmodified boron-doped diamond electrode
(Elsevier Science Sa, Lausanne, 2016)
Pyridoxine (vitamin B-6, VB6) was detected in pharmaceutical preparation and human urine samples by employing differential pulse voltammetry (DPV) at unmodified boron doped electrode. In Britton-Robinson buffer solution ...
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 ...
Sensitive voltammetric determination of thymol in essential oil of Carum copticum seeds using boron-doped diamond electrode
(Academic Press Inc Elsevier Science, San Diego, 2015)
Essential oil of Carum copticum seeds, obtained from a local shop, was extracted and content of thymol was analyzed using square-wave voltammetry at boron-doped diamond electrode. The effect of various parameters, such as ...
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 ...
Carbohydrate – Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations
(Elsevier, 2020)
The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallography structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were ...
Investigation of mechanism and critical parameters for removal of arsenic from water using Zr-TiO2 composite
(Taylor & Francis Ltd, Abingdon, 2017)
Using the microwave-hydrothermal method for the synthesis of composite, high surface density of hydroxyl groups, as an active adsorption sites for arsenic, was obtained. Adsorption mechanisms of As(III) and As(V) onto ...
