Tetrasodium etidronate (Na4 etidronate) and tetrasodium EDTA (Na4 EDTA) are chelators that can combine with sodium hypochlorite (NaOCl) as a 1-mix endodontic irrigant in a process called continuous chelation. The therapeutic window of these mixtures is determined by the chemical reaction between NaOCl and the chelator.

AbstractRecently, the EDTA‐based sweeping of metal ion that combines chelate formation and in‐line sample pre‐concentration was advanced. However, the moving chelation boundary (MCB) existing in the sweeping system has not been investigated for the quantitative illumination of the mechanism of metal ion sweeping yet. In this paper, the model of MCB was

From an assessment of multiple chelators, clodronate has potential for use in continuous chelation
International Endodontic Journal, 2019AbstractAimTo identify chelators which when mixed with sodium hypochlorite (NaOCl) are stable, exhibiting minimal loss of free available chlorine (FAC) over 80 min and to further investigate potential mixtures by assessing FAC over 18 h and the capacity to remove smear layer.Methodology0.25 mol L−1 EDTA (10%), 0.25 mol L−1 EGTA (egtazic acid), 0.25 mol

To further examine the potential clinical usefulness of the hexadentate phenolic aminocarboxylate iron chelatorN,N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) for the chronic treatment of transfusional iron overload, we performed a subchronic toxicity study of the HBED monosodium salt in rodents and have evaluated the iron excretion ...

Continuous chirality measures of tetracoordinate bis(chelate) metal complexes
Dalton Transactions, 2003The interconversion pathway between the tetrahedron and the square that is represented by the structures of a large variety of tetracoordinate complexes is the achiral spread pathway in the presence of monodentate ligands but the chiral twist pathway in bis-chelated complexes.

Continuous chirality analysis of hexacoordinated tris-chelated metal complexes
Crystal Engineering, 2001We use the notion that symmetry can be evaluated on a continuous scale for the quantitative chirality analysis of tris-chelated metal complexes. After reviewing the Continuous Symmetry Measures methodology and its resulting Continuous Chirality Measure, we analyze the chirality of these complexes in terms of the specific contributions from the ...

Exploring the Influence of Chelating Agents on Particle Formation in Continuous Coprecipitation
ECS Meeting AbstractsThis talk discusses the role of chelating agents in influencing the electrochemical performance of transition metal hydroxide-based cathode materials for energy storage applications. The focus is placed on how variations in the molar ratios of different chelating agents during ammonia-free continuous coprecipitation processes affect particle formation,

This paper introduces a mathematic mode of moving chelation boundary (MCB) for computer simulation of a continuous EDTA-based sample sweeping in capillary electrophoresis (CE). Besides the equations of MCB used herein, the mode also includes electro-neutrality equation, constant current density, jump boundary condition of MCB, Kohlrausch' regulating ...

The Analyst, 2010
A novel separation mode of isotachophoresis (ITP) was advanced for the study on the continuous moving chelation boundary (MCB) formed with EDTA and two metal ions of Co(II) and Cu(II). The experiments were performed systemically. The relevant results indicated that: (1) there were three boundaries in the whole system, viz., a sharp MCB, a wide moving ...

Through its production of phosphatidic acid (PA), phospholipase D (PLD) is strongly involved in vesicular trafficking and cell signaling, making this enzyme an important therapeutic target. However, most PLD assays developed so far are either discontinuous or based on the indirect determination of choline released during PLD-catalyzed ...
