Bacterial degradation of 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE) has been previously reported, however, its degradation enzyme system has not been characterized. In this study, a DDE-degrading bacterium, Janibacter sp. TYM3221, was isolated and characterized. Transformation of DDE was...

A DDE-degrading bacterium, Janibacter sp. TYM3221, is able to grow on biphenyl and degrades 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE) via a meta-ring cleavage pathway. The bphAa gene, encoding a biphenyl dioxygenase large subunit, was previously demonstrated to be involved in the degrad...

Acylimidodicarbonates obtained from aziridine-2-carboxamides through Davidsen bis-Boc activation react with amine nucleophiles under mild conditions to form tertiary aziridine-2-carboxylic acid amides. NH aziridine-2-carboxylic acid amides were obtained by hydrogenolythic deprotection of N-Cbz d...

Biological activities of two epimeric 24-fluorinated vitamin D-2 analogs, 24-fluoro-1α,25-dihydroxyvitamin D-2 [24-F-1,25-(OH)2D2] and its 24-epimer [24-epi-24-F-1,25-(OH)2D2], were studied and compared with 1α,25-dihydroxyvitamin D-3 [1,25-(OH)2D3] and 1α,25-dihydroxyvitamin D-2 [1,25-(OH)2D...

Antibacterial/antibiofilm potential of microwave-assisted synthetic thirty-three 2-amino-5-chloro benzophenone Schiff bases have been carried out against four bacterial strains i.e. Klebsiella pneumoniae, Proteus mirabilis, Staphylococcus aureus and Streptococcus mutans. Among them compounds 5, ...

Dissipation kinetics of mixed formulation consisting beta-cyfluthrin and imidacloprid in tea crop under an open field ecosystem was investigated. The mixed formulation was applied on tea plant at recommended (27 + 63) and double the recommended (54 + 126 g a.i./ha) dose and residues were determi...

Environmental impact of pesticides is one of the great concerns being addressed by water-food nexus research. Imidacloprid is one of the most used insecticides as an alternative for carcinogenic organochloride insecticides. Even though Imidacloprid has lower toxicity for mammals, its fate and in...

The neonicotinoid insecticide imidacloprid is used in Bangladesh for a variety of crop protection purposes. Imidacloprid may contaminate aquatic ecosystems via spray drift, surface runoff and ground water leaching. The present study aimed at assessing the fate and effects of imidacloprid on stru...

Groundwater is one of the main freshwater resources on the Earth, but its contamination by NO3− and pesticides jeopardizes its suitability for consumption. In this work, the simultaneous electro-oxidation of insecticide imidacloprid (IMC) and electroreduction of NO3− in softened groundwater cont...

The degradation of imidacloprid in soil and its uptake and translocation to chili and tomato plants was evaluated, as a proof of concept, of the possibilities of the combination of molecularly imprinted polymers (MIPs) and ion mobility spectrometry (IMS) for a fast and sensitive bioprocesses mon...

This study focused on the fabrication of a rapid, highly sensitive and inexpensive technique for the quantification of imidacloprid residue in green tea, based on surface-enhanced Raman scattering (SERS) using highly roughned surface flower shaped silver nanostructure (as SERS substrate) coupled...

Systematically evaluation of the metabolism, distribution and effect of imidacloprid in Chinese lizards (Eremias argus) were carried out following oral exposure. Imidacloprid-olefin-guanidine was prone to accumulate in the brain and caused potential neurotoxicity. Percutaneous and excretory excr...

The purpose of this work was the comparison of imidacloprid transformation in heterogeneous photocatalysis (TiO2), UV254 nm photolysis, UV254 nm/VUV185 nm photolysis and γ-radiolysis (also pulse radiolysis) in the presence and absence of dissolved oxygen, and the identification of intermediates...

Neonicotinoid insecticides such as imidacloprid, indoxacarb and thiamethoxam are widely used for control of a large number of insect pests of pomegranate crop. Their residue levels were evaluated on pomegranate fruits over 2 years during the same cropping season. The QuEChERS analytical method i...

Neonicotinoid pesticides have recently drawn attention worldwide owing to their potential adverse effects on non-target organisms and ecosystems. Exposure to imidacloprid, the most widely used neonicotinoid insecticide, is of particular concern among rural populations because of its ubiquitous u...

The cytotoxicities of 11 lupane series triterpenes against 3 human leukemias, 2 melanomas, 2 neuroblastomas and normal fibroblast cells were examined. Lupane triterpenes with a carbonyl group at C-17 (7–11) showed inhibitory effects on leukemia, melanoma and neuroblastoma cell growth. Lup-28-al...

This study focused on the design and fabricating of a new type of hydroxyl anion conducting membranes employing the interpenetrating polymer network (IPN) comprising poly (vinyl alcohol) (PVA) and linear structured poly bis(2-chloroethyl) ether-1,3-bis [3-(dimethylamino)propyl] urea copolymer (P...

A series of Mg/Al carbonate layered double hydroxides (LDHs) with different Mg/Al ratios and their calcined LDHs (CLDHs) were prepared as a promising adsorbent of perchlorate anionic pollutant. The LDHs, CLDHs and reconstructed LDHs were characterized by X-ray diffraction, SEM, Raman and FTIR sp...

Layered double hydroxides (LDHs) as a class of anionic clays have extensive applications due to their unique structures. Nowadays, the emphasis is laid on the development of LDH coatings for corrosion resistance and medical applications. Thus, this review highlights synthetic methods of LDH coat...

Carbonate ion-intercalated Mg–Al layered double hydroxides (CO3-type Mg–Al LDHs) were prepared by using various methods to mix a solution of Mg(NO3)2 and Al(NO3)3 with an alkaline solution, and the particle properties of the obtained samples were compared. By mixing stoichiometric quantities o...
