We evaluated the inducibility of nitrate-dependent Fe(II)-EDTA oxidation (NDFO) in non-growth, chloramphenicol-amended, resting-cell suspensions of Dechloromonas sp. strain UWNR4 and Acidovorax sp. strain 2AN. Cells previously incubated with Fe(II)-EDTA oxidized ca. 6-fold more Fe(II)-EDTA than cells previously incubated with Fe(III)-EDTA. This is the first report of induction of NDFO by Fe(II).

Abstract Ethylenediaminetetraacetic acid disodium (EDTA) can form stable complexes with many metals. To improve the leaching rate of gold and consumption thiosulfate, EDTA ammonia were combined copper ions to a copper-EDTA-ammonia-thiosulfate system. Electrochemical methods used study effect ion, EDTA, polarization voltage. The results showed that increasing concentrations ions, promoted dissol...

EDTA can complex with radionuclides (RNs) to form negatively charged complexes, making it difficult for clay minerals retard the diffusion of RNs waste. The coefficient in water ( D w ) is an important parameter safety assessment repository. In this study, effectsof on metal ions (Cu 2+ , Sm 3+ Nd Lu and Zn were investigated by a capillary method. experimental results showed that [Cu-EDTA] 2- [...

The aim of this study was to compare the influence a final rinse with and without passive ultrasonic irrigation (PUI), using 17% ethylenediaminetetraacetic acid (EDTA) or 10% citric (CA), 2.5% sodium hypochlorite (NaOCl) PUI, on sealing ability root canal fillings. Root instrumentation performed in single-rooted premolars NaOCl as irrigant. Subsequently, roots were randomly allocated into four ...

Through the esterification of cellulose (Cell) with ethylenediaminetetraacetic dianhydride, acid-functionalized (Cell-EDTA) was conveniently obtained. Furtherly a novel and efficient Cell-EDTA-supported palladium catalyst (Pd@Cell-EDTA) easily prepared via coordination Cell-EDTA PdCl2. The as-prepared Pd@Cell-EDTA fully characterized by inductively coupled plasma atomic emission spectrometry, X...

A practical synthesis of 1-bromo-2-amino-3-butene derivatives from homoallylic trichloroacetimidates was reported. Simply heating the mixture of substrates and N-bromoacetamide in DMF at 90 °C would give the desired products in moderate to excellent yields. The reaction may proceed through a domino bromo-cyclization and elimination pathway. The synthesis of 4,5-dihydrooxazoles from 1-bromo-2-am...

We performed ultrafast pump-probe spectroscopy of J-aggregates of 3,3'-disulfopropyl-5,5'-dichloro-9-ethyl thiacarbocyanine triethylammonium (THIATS), one of the most typical cyanine dyes, and detected excited molecular vibrations, using a sub-10 fs pulse laser. The time-resolved two-dimensional difference absorption (ΔA) spectra are observed between -314 and 1267 fs. By performing the Fourier ...

Objective: This study aimed to evaluate whether platelet indices and leukocyte count predict the diagnosis of Ethylene Diamine Tetra Acetic Acid induced pseudothrombocytopenia (EDTA-PTCP) differ this entity from immune thrombocytopenia (ITP). Methods: One-hundred sixty-nine individuals (52 patients diagnosed with EDTA-PTCP, 52 newly ITP, 65 healthy individuals) were included. Demographic data c...
