Apoptotic and necrotic effects of carboxylated quercetin/polyethylenimine complex on HeLa cells
(Academic Journals, 2011)The effects of quercetin (Q), carboxylated quercetin (CQ) and carboxylated quercetin/polyethylenimine (CQ/PEI) complex on HeLa cell cultures were investigated. Firstly, carboxylated quercetin was acquired through hydroxyl ... -
Apoptotic and necrotic effects of plant extracts belonging to the genus Alchemilla L. species on HeLa cells in vitro
(Academic Journals, 2011)Apoptotic and necrotic effects of plant extracts belonging to the genus Alchemilla on HeLa cells were investigated. The ratio of viable cells was determined by cell counter. Double staining method for the determination of ... -
Application of FAM ligands in the metal-promoted catalytic enantioselective synthesis of organic compounds
(Scientific Technical Research Council Turkey-Tubitak, 2009)Novel ferrocenyl substituted aziridinyl methanol (FAM) ligands were synthesized and successfully used in metal-promoted catalytic enantioselective azomethine ylide cycloadditions, diethylzinc additions to enones, alkynylzinc ... -
Application of NaOH treated Polyporus versicolor for removal of divalent ions of Group IIB elements from synthetic wastewater
(Elsevier Sci Ltd, 2002)Three different forms of Polyporus versicolor, i.e. alkali-pretreated, heat-inactivated and active, were used for the removal of the divalent ions of Group JIB elements from aquatic systems. The biosorption of Zn(II), ... -
An application of Ritt-Wu's zero decomposition algorithm to null Bertrand type curves in Minkowski 3-space
