Bis-(L-tyrosinato)copper(II) was reacted with 3-(chloropropyl)-trimethoxysilane functionalized silica that has infused magnetite to yield a magnetically separable catalyst in which the copper carboxylate is covalently linked to the silica matrix through the silane linkage. The immobilized catalyst has been characterized by spectroscopic studies (such as FT-IR, EPR, Magnetic Measurement...
The present study was aimed to enzymatic antioxidants (superoxide dismutase, catalase, polyphenol oxidase), nonenzymatic (saponin, flavonoids, ascorbic acid and tannin), anti-oxidant ability assays (total anti-oxidant, hydroxyl radical scavenging ability, reducing power activity, inhibition of lipid peroxide formation, DPPH activity metal chelating assay) in I. marginata leaves whole plant. res...
The bicistronic microRNA (miRNA) locus miR-144/451 is highly expressed during erythrocyte development, although its physiological roles are poorly understood. We show that miR-144/451 ablation in mice causes mild erythrocyte instability and increased susceptibility to damage after exposure to oxidant drugs. This phenotype is deeply conserved, as miR-451 depletion synergizes with oxidant stress ...
a two-dimensional nanolayered polyoxomolybdate, [4,4´-h2bipy] [mo7o22].h2o (1), where 4,4´-bipy = 4,4´-bipyridine, was prepared and characterized by ft-ir and atomic absorption spectroscopies, transmission electron microscopy (tem), x-ray single crystal and powder diffraction (xrd), and thermogravimetric analysis. the catalytic performance of 1 was assessed in the epoxidation of some olefins em...
Therapeutic potential of medicinal plants as a source of noble natural anti-oxidants and anti-microbial agents has been well recognised all across the globe. In this study, phenolic compounds, in vitro anti-oxidant activity and anti-microbial properties have been investigated in five Himalayan medicinal plants, (e.g., Acorus calamus, Habenaria intermedia, Hedychium spicatum, Roscoea procera and...
The total antioxidant activities of seven different vegetables were measured by FRAP method together with their estimation of total phenolic content by Folin-Ciocalteau method. Coriander and tomato belonged to high antioxidant activity group. In the medium group; capsicum, carrot and onion scored anti-oxidant activity of 5.65, 3.46 and 4.24 μ M Fe2+ /g FW respectively. Cucumber and radish were ...
