The Effects of Sequential and Continuous Chelation on Dentin
Dental Materials, 2020 Proteolytic and demineralizing agents have a profound influence on the dentin ultrastructure, which plays a key role in the mechanical integrity of the tooth and integrity of dentin-biomaterial interfaces. In-depth characterization of dentin treated with a novel root canal irrigation protocol comprising sodium hypochlorite (NaOCl) and etidronate (HEDP)

Journal of Endodontics, 2019 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.

Continuous Soft Chelation in Endodontics
RGUHS Journal of Dental Sciences, 2022Chemome chanical debridement is accompanied by three-dimensional obturation of the root canal system in endodontic therapy. Endodontic irrigation requires sodium hypochlorite (NaOCl) as it dissolves organic matter and disinfects the root canal. The smear layer is removed by chelating agents.

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

Journal of Water Process Engineering, 2022
The objective of this work is to develop an advanced adsorption process to continuously recover boron from brines, named as the multicolumn simulated moving bed process. Firstly, the adsorption and desorption performances of boron on the commercially available N-methylglucamine resins are investigated, then, the cyclic adsorption and desorption ...

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 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 ...

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.

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 ...
