Abstract Disposing of residual cooking oil is a major environmental concern, so its conversion into commercial products desirable goal. To design the chemical modification domestic waste valuable biochemicals other than biodiesel, we analyzed series samples, collected over period three years, using quantitative 1 H-NMR. This analysis, allowing quick determination main characteristics, has rende...

Introduction: Human adipose-derived mesenchymal stem cells (hADSCs) are easily accessible in the body, and under appropriate conditions, they can be directed toward various phenotypes. Therefore, hADSCs have been considered as a potential cell source for tissue engineering applications. hADSCs are able to differentiate into endothelial cells which covers the interior surface of vessels, in vi...

The sialic acids can have O-acetyl esters at the 4, 7, 8, and 9 positions. Most methods for the detailed study of such molecules require their release from glycosidic linkage, followed by extensive purification. The currently used methods for release and purification of sialic acids allow a reasonable qualitative analysis of the diversity of sialic acids from a given biological source. However,...

The one-pot four component synthesis of 3-(Imino)-2,3-dihydropyrrolo[2,1-a]isoquinoline-1,1(10bH)-dicarbonitrile derivatives via a catalyst-free reaction between aryl aldehydes, malononitrile, isoquinoline and isocyanides was successfully conducted in glycerol as a benign, nontoxic and biodegradable promoting reaction medium. The progress of the reaction with two different common purification m...
