The paper describes a new method for the determination of phosphonates by ion-pair high-performance liquid chromatography. The phosphonates are complexed with Fe(III) and separated on a reversed-phase...Read More
Conjugative transfer of plasmid DNA via close cell-cell junctions is the main route by which antibiotic resistance genes spread between bacterial strains. Relaxases are essential for conjugative trans...Read More
Adsorptive removal of nitrilotris(methylenephosphonic acid) antiscalant from membrane concentrates by iron-coated waste filtration sand
Iron-coated waste filtration sand was investigated as a low-cost adsorbent for the removal of nitrilotris(methylenephosphonic acid) (NTMP) from membrane concentrates. The adsorption of this phosphonat...Read More
An ATR-FTIR study of the vibrational spectra of N,N-bis(2-hydroxyethyl) aminomethylphosphonic acid (BHAMP), 1-hydroxyethane-1,1'-diphosphonic acid (HEDP) and nitrilotris(methylenephosphonic acid)...Read More
Hydrolysis of single linkage in long DNA using oligonucleotide-multiphosphonate conjugates and Ce IV/EDTA.
Only one phosphodiester linkage in long DNA was hydrolyzed simply by using two components: oligonucleotide-multiphosphonate conjugates ("gapmers") and Ce(IV)/EDTA (Fig. 1)....Read More
Ce(IV)-catalyzed site-selective DNA hydrolysis using tris- and tetrakismethylenephosphonate-modified oligonucleotides.
To improve the recruitment of the catalytically active Ce(IV) ion to the DNA cleavage site in the ARCUT (Artificial Restriction DNA Cutter) system, two phosphonate ligands, nitrilotris(methylenephosph...Read More
Potentiometric studies of binary and ternary complexes involving cadmium(II) and nitrilo-tris(methyl phosphonic acid) with amino acids, peptides and DNA constituents.
The complexing properties of nitrilo-tris(methylphosphonic acid) (NTP) with cadmium(II) were investigated pH-metrically at 25 degrees C and at ionic strength of 0.1 mol dm(-3) (NaNO3). Stoichiometry a...Read More
The aim of this study was to assess interactions of EDTA and citric acid (CA) with sodium hypochlorite (NaOCl), the indispensable endodontic irrigant. Other chelators were simultaneously evaluated as ...Read More
Adsorption of phosphonate antiscalant from reverse osmosis membrane concentrate onto granular ferric hydroxide.
Adsorptive removal of antiscalants offers a promising way to improve current reverse osmosis (RO) concentrate treatment processes and enables the reuse of the antiscalant in the RO desalination proces...Read More
[Hygienic establishment of maximum permissible concentrations of nitrilotrimethylphosphonic acid and a copper-containing complex in reservoir water].
Site-specific rate constants for iron removal from diferric transferrin by nitrilotris(methylenephosphonic acid) and pyrophosphate.
The kinetics of iron removal from human serum diferric transferrin by nitrilotris(methylenephosphonic acid) (NTP) and pyrophosphate (PPi) have been studied in 0.1 M, pH 7.4, N-(2-hydroxyethyl)piperazi...Read More
