This study investigated the effect of extracts of different composites, glass ionomer cement (GIC)s and compomers on the viability of brine shrimp larvae. Ethanolic extracts of four dental composites (Z-100; Solitaire 2; Filtek P60 and Synergy), a conventional GIC (Ketac-Fil), a resin-modified glass ionomer cement (Vitremer), two compomers (F2000; Dyract AP), and a flowable compomer (Dyract Flo...

Brine shrimp are incapable of synthesizing purines de nova and seemingly have a complex nucleotide metabolism involving conversion of stored diguanosine 5’, 5/“-(PI, P4tetraphosphate) into ATP. When nucleosides uniformly labeled with 14C are administered to the organism, its ATP shows an unusual labeling pattern. When [UJ4C]adenosine is used as a precursor, the purine moiety is primarily incorp...

Mammea siamensis (Miq.) T. Anders. (Calophyllaceae) plants have long been employed as an active integral composition in Thai traditional medicine. Additionally, phenylcoumarins and triterpenes were reported major components phytochemical research. This work explored the various parts of M. siamensis; barks, flowers, twigs, leaves, young leaves; to determine their bioactive compounds. By using G...

As part of a project aimed at investigating the Matthiola taxa endemic to Sicily (Italy), this study focused on incana, an edible species used in traditional medicine various countries. Herein, characterization phenolic and volatile compounds, antioxidant capacity vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power Fe2+ chelating activity assays) toxicity test (Artemia salina lethality ...

numerous studies have been focused on natural anticarcinogenic agents. many antioxidants have been identified as anticarcinogens. antimutagens have also been proposed as cancer chemopreventive agents. the use of natural products as anticancer has a long history that began with traditional medicine. the aim of this study was to evaluate cytotoxicity and antioxidant activity of twenty-three plant...

the present study was intended to standardize the protocol for the synthesis of silver nanoparticles (agnps) using aqueous extract of dictyota bartayresiana j.v. lamouroux and evaluate cytotoxic potentials using brine shrimp bio-assay activity and trypan blue dye exclusion method. the reduction of pure ag+ ions was monitored by measuring the uv-vis spectrum of the solution at 200-900 nm and the...

General toxicity, antiproliferative, antibacterial and antioxidant activities of Caulerpa peltata J.V.Lamouroux (Caulerpaceae) collected from Oman Sea were investigated. Dried, ground alga was Soxhlet-extracted with hexane, dichloromethane and methanol successively. The methanol extract was subjected to vacuum liquid chromatography (VLC) fractionation on silica gel using a step gradient of diff...
