1. Insoluble salts of alklaine earth metals (e. g. calcium phosphate) dissolve in non-aqueous solvents containing EDTA salts of organic cations (e.g. tetraethylammonium). 2. Bone is efficiently demineralized in ethanolic trimethylammonium EDTA. Retention in the matrix of water-soluble materials (e.g. proteoglycan) is much better than in standard aqueous EDTA demineralization procedures.

To examine the hypothesis that EDTA increases hatching rates and survival of penaeid shrimp larvae by decreasing the toxicities of heavy metals through chelation, the toxicity of cadmium, a highly toxic metal, was compared to the toxicities of calcium and phenol in both the presence and absence of EDTA. In addition, the toxicity of EDTA at higher concentrations was examined. The toxicities of E...

In ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP), automated platelet counts are lower than actual counts because of EDTA-induced aggregation. Factors contributing to the incidence of EDTA-PTCP are unknown, and no study has assessed the prognosis of EDTA-PTCP patients. This retrospective study assessed characteristics in EDTA-PTCP patients and matched controls to...

Crystal structure determinations on the uranyl ion complexes [H2N(CH3)2]2[UO2(bpdc)2], (1), (bpdc = 2,2′-bipyridine-3,3′-dicarboxylate), [pyH]2[UO2(btfac)(NO3)2](NO3), (2), (btfac 1-phenyl-4,4,4-trifluorobutane-1,3-dionate), [H2dabco][UO2(nta)]2·3H2O, (3), (dabco 1,4-diazabicyclo[2.2.2]octane; nta nitrilotriacetate) and [Ni(cyclam)UO2(edta)].2H2O, (4), (cyclam 1,4,8,11-tetrazacyclotetradecane; ...

This study evaluated the effect of EDTA and lysozyme on the antibacterial activities of activated ovotransferrin against 5 strains of Listeria monocytogenes. First, a disc test was performed to screen the concentrations of EDTA or lysozyme that showed antibacterial activities in ovotransferrin (O) or ovotransferrin in 100 mM NaHCO3 (OS) solution. Turbidity and viability tests were conducted usi...

Este trabalho descreve um estudo da reação de ancoramento de H[Ru(III)Cl 2 (H 2 EDTA)].4.5 H 2 O na superfície da sílica gel funcionalizada (SF) com o composto [3-(2aminoetil)aminopropil]trimetoxissilano (AEATS), gerando por meio de ligação amida o composto dimérico (EDTA) 2 Ru 2 (IV,IV) na superfície da sílica modificada. A oxidação da água por esse complexo imobilizado na superfície da sílica...

EDTA inhibits horseradish peroxidase (HRP)-catalysed iodide oxidation in a concentration and pH-dependent manner. It is more effective at pH 6 than at lower pH values. A plot of log Kiapp. values as a function of pH yields a sigmoidal curve from which a pKa value of 5.4 can be calculated for an ionizable group on the catalytically active HRP for EDTA inhibition. Among the structural analogues o...

Background: Escherichia coli and Staphylococcus aureus as important food-borne pathogens are the main concerns of food producers and consumers which create a lot of problems worldwide. The objective of this study was to investigate the inhibitory effect of monolaurin alone and in combination with EDTA on viability of E. coli and S. aureus in culture media and Iranian white cheese. Methods: Th...
