Myeloperoxidase-mediated oxidation of organophosphorus pesticides as a pre-step in their determination by AChE based bioanalytical methods
(Springer Science and Business Media LLC, 2010)
In order to improve the sensitivity of assays for inhibitors of the enzyme acetylcholine esterase (AChE), an effective method was developed for the conversion of the organophosphate pesticides (OPs) diazinon, malathion, ...
Phenolic Compounds from Atriplex littoralis and Their Radiation-Mitigating Activity
(American Chemical Society (ACS), 2015)
From the aerial parts of Atriplex littoralis, three new flavonoid glycosides named atriplexins I-III (1-3), a known flavonoid glycoside, spinacetin 3-O-beta-D-glucopyranoside (4), arbutin (5), and 4-hydroxybenzyl-beta-D- ...
Montmorillonite/poly(urethane-siloxane) nanocomposites: Morphological, thermal, mechanical and surface properties
(Elsevier, 2017)
The aim of this work was to prepare and characterize the series of segmented polyurethane nanocomposites (PUNC) modified with poly(dimethylsiloxane) and based on montmorillonite (Mt) as a nano-filler. alpha,omega-Dihydro ...
Voltammetric behavior of erythromycin ethylsuccinate at a renewable silver-amalgam film electrode and its determination in urine and in a pharmaceutical preparation
(Oxford : Pergamon-Elsevier Science Ltd, 2016)
Erythromycin, a macrolide antibiotic, has similar antimicrobial spectrum to penicillin and it is widely used, especially in the treatment of patients who are allergic to penicillin. In this work, the application of a ...
Chemical composition, cytotoxic and antioxidative activities of ethanolic extracts of propolis on HCT-116 cell line
(Wiley, Hoboken, 2013)
BACKGROUND Propolis is a complex resinous sticky substance that honeybees collect from buds and exudates of various plants. Owing to its versatile biological and pharmacological activities, propolis is widely used in ...
Influence of film formation on light-trapping properties of randomly textured silicon thin-film solar cells
(The Japan Society of Applied Physics, 2014)
The influence of film formation on light-trapping properties of silicon thin-film solar cells prepared on randomly textured substrates was studied. Realistic interface morphologies were calculated with a three-dimensional ...
The DsbA signal peptide-mediated secretion of a highly efficient raw-starch-digesting, recombinant alpha-amylase from Bacillus licheniformis ATCC 9945a
(Elsevier Sci Ltd, Oxford, 2013)
In this study, a new approach for extracellular production of recombinant alpha-amylase in Escherichia coli was investigated. A gene encoding a highly efficient raw-starch-digesting alpha-amylase from Bacillus licheniformis ...
Palladium-copper bimetallic surfaces as electrocatalysts for the ethanol oxidation in an alkaline medium
(Elsevier, 2023)
Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C), and ...
Influence of Short Central PEO Segment on Hydrolytic and Enzymatic Degradation of Triblock PCL Copolymers
(Springer, 2018)
Hydrolytic, enzymatic degradation and composting under controlled conditions of series of triblock PCL/PEO copolymers, PCEC, with central short PEO block (M (n) 400 g/mol) are presented and compared with homopolymer (PCL). ...
Aromaticity of Diazaborines and Their Protonated Forms
(American Chemical Society (ACS), 2016)
Substitution of a CH group in benzene with nitrogen has a little effect on its aromaticity (Wang et al, Org. Lett. 2010, 12, 4824). How does the same type of substitution affect aromatic character of the three isomeric ...
