The synthesis of ZnFe2O4 nanoparticles was performed using the solution combustion method with three types fuel, namely urea, glycine, and ethylenediamine tetra-acetic acid (EDTA) precursors (Zn(NO3)2.6H2O Fe(NO3)3.9H2O. process conducted in an open space at 300 °C for ± 1 h, resulting a brownish-black ZnFe2O4. Meanwhile, fuel type used affects physicochemical properties XRD analysis showed tha...

By optimizing the raw material ratio for preparation of ethylenediaminetetraacetic acid-type chitosan (EDTA-type chitosan), extraction efficiency rare earth elements was improved. The synthesis with a lower concentration to acetic acid than that in previously reported method confirmed by IR spectra peak assigned as carboxyl group EDTA drastically decreased and amide bond reaction between more f...

Root canal irrigants are used to minimize the negative effects of smear layer on endodontic sealer retention. The aim of this study was to evaluate the efficacy of agitation of 17% ethylenediaminetetraacetic acid (EDTA) with ultrasonic, 1064-nm Nd:YAG and 980-nm diode laser on the retention of an epoxy-based sealer to the root canal walls. Forty single-rooted bovine teeth were instrumented with...

The colicin A lysis protein, Cal, is synthesized at the same time as colicin A by Escherichiu coli harbouring plasmid pColA after induction by mitomycin C. Its function in the induced bacteria involves the release of colicin A, quasi-lysis, the death of the producing cells and the activation of the outer membrane phospholipase A. We have found that these various functions are affected different...

Cold plasma and ozone sanitation of irrigation solutions can oxidize both microbes non-target micronutrients because their high oxidation-reduction potential (ORP) is a non-selective mode action. The objective this study was to evaluate the effects cold treatment on oxidation iron manganese in nutrient containing one four chelates (iron-ethylenediaminetetraacetic acid (Fe-EDTA), iron-diethylene...

Objective: This study aims to estimate and compare the time-course change in blood glucose levels by blood cells in serum, and plasma with or without preservatives, which may reflect the rate of glucose utilization by blood cells. Method: This laboratory-based cross-sectional study was carried out using a blood specimen of 28 participants among which 14 were diagnosed with diabetes and 14 were...

Phosphotriesterase (PTE) activities in mammalian serum are typically found in the lipoprotein fraction. This PTE requires Ca++ for activity and is consequently inactivated by ethylenediaminetetraacetic acid (EDTA). There is also a little known PTE in mammal serum that is resistant to EDTA inactivation. In this work, the PTE activities for the substrates O-hexyl O-2, 5-dichlorophenyl phosphorami...

OBJECTIVE This study aims to compare the clot stabilization on root surfaces conditioned with citric acid and ethylenediamine-tetraacetic acid (EDTA). MATERIALS AND METHODS Scaled root samples (n = 100) were set in fve groups: group I-control group (saline solution); group II (24% EDTA); group III (25% citric acid); group IV (EDTA + citric acid); group V (citric acid + EDTA). Fifty samples we...
