Synthesis of 5-arylidine thiobarbituric acids containing different functional groups with variable electronic characters were described and their Co(2+), Ni(2+) and Cu(2+) complexes. The stereochemistry and mode of bonding of 5-(substituted benzylidine)-2-TBA complexes were achieved based on elemental analysis, spectral (UV-VIS, IR, (1)H NMR, MS), magnetic susceptibility and conductivity measur...

Carnosine, homocarnosine and anserine have been proposed to act as antioxidants in vivo. Our studies show that all three compounds are good scavengers of the hydroxyl radical (.OH) but that none of them can react with superoxide radical, hydrogen peroxide or hypochlorous acid at biologically significant rates. None of them can bind iron ions in ways that interfere with 'site-specific' iron-depe...

A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular organelles. These included sucrose (up to 100 mM final concentration in the assay medium), Tris-maleate (up to 40 mM), imidazole (up to 20 mM), inorganic phosphate (up to 10 mM), an...

AIMS To evaluate the effects of allopurinol in lens induced uveitis (LIU) by morphological methods and to compare these effects with those of steroids and a combination of both drugs biochemically and morphologically. METHODS Lipid peroxides (LPO) of the retinal tissue were determined by two different methods (thiobarbituric acid assay (TBA) and high performance liquid chromatography expresse...

A survey was conducted in Hisar, located Haryana, India, to assess the quality of raw chicken meat. To ensure comprehensive coverage, healthy broiler chickens were obtained from various meat retail outlets Hisar city, encompassing majority such establishments. Additionally, a sample control Livestock Farm, College Veterinary Sciences, Lala Lajpat Rai University and Animal Sciences (LUVAS), Indi...

In this study, hot smoking process was applied to thornback ray (Raja clavata), which is a non-target catch, and the product obtained vacuum packaged then stored at refrigerated conditions (4±1 °C) for 120 days. The nutritional, chemical, microbiological, sensory changes in products were examined every 15 After rays, significant observed nutritional composition of (P<0.05). Total volatil...

A number of nucleobase-based barbiturates have been synthesized by combination of nucleic acid bases and heterocyclic amines and barbituric acid derivatives through green and efficient multicomponent route and one pot reaction. This approach was accomplished efficiently using aqueous medium to give the corresponding products in high yield. The newly synthesized compounds were characterized by s...

Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...

the present study evaluated the effect of packaging (air, vacuum) with or without addition of sodium acetate (2% w/v) on shelf-life extension of rainbow trout (oncorhynchus mykiss) under refrigeration, for a period of 18 days. four different treatments were tested: cap: control air pack; saap: sodium acetate treated aerobic packaging; vp: vacuum packaging in the absence of sodium acetate; and s...

the use of natural extracts as one of good antioxidant source is increasing to improve fish quality. the present study aims at investigating antioxidant effect of orange peel extract on the quality of common carp fillet during refrigerated storage (4°c). fish fillets were treated by 0, 1 and 5 % concentration of orange peel extract, packed and then stored in refrigerator. chemical parameters (p...
