In Korea, for heavy metal-contaminated soil, there are insufficient basic data as well field application cases soil washing. This study was conducted to suggest the significant factors and optimal operation conditions maximum metal removal efficiency. Five types of washing solution [acid (HCl), citric acid, oxalic EDTA, CaCl2], time (10–360 min), solid-solution ratio (1:2–1:100) were selected o...

The chelating and antimicrobial capacity of a novel modification of 17% EDTA with silver nanoparticles (AgNPs) (EDTA-AgNPs) was evaluated in-vitro for root canal treatment (RCT). The EDTA-AgNPs solution was characterized by UV-Vis spectroscopy, ζ-potential and high-resolution transmission electron microscopy (HRTEM). Antimicrobial capacity was evaluated against Candida albicans and Staphylococc...

The aim of this study was to evaluate the effect of irrigation regimens on dentin microhardness at the furcation area of mandibular molars, using sodium hypochlorite and ethylenediaminetetraacetic acid (EDTA), individually and in alternation. The occlusal surface and the roots of 20 non-carious extracted human permanent mandibular molars were cut transversally and discarded. The tooth blocks we...

Aim- The aim of this in-vitro study was to compare the effect NaOCl, EDTA, Propolis and Distilled water on cyclic fatigue resistance Protaper Gold rotary NiTi instruments.
 Method- A total 40 commercially available (n =40) Ni-Ti files were used assess different root canal irrigants their resistance. divided into four groups (n=10 per group) as Group 1- (Control group), 2 – 5.25 % 3 -17% ED...

1 The effects of the disodium salt of ethylenediamine tetra-acetate (EDTA) and 1, 2, bis, 2 aminoethoxyethane-NNN'N'-tetra-acetic acid (EGTA) on renin secretion and vascular resistance were studied in the isolated perfused kidney of the rat. 2 Both substances produced a significant increase of renin release 3 In the absence of calcium and magnesium, EDTA still increased rein release and there w...

Chelating and ion-exchange N-functionalized mesoporous silicas (SBA-15) as selective adsorbents for removal of heavy metals were synthesized using template method. Fourier transform infrared spectroscopy, TEM analysis, N2 adsorption/desorption isotherms titration analysis confirmed successful functionalisation the tri-sodium salt N-(triethoxysilylpropyl)ethylenediaminetriacetic acid (EDTA), pro...

In the title complex, [Co(C(22)H(18)N(2)O(4))(CN)(H(2)O)]·0.5CH(3)CN, the Co(III) cation is N,N',O,O'-chelated by a 6,6'-dimeth-oxy-2,2'-[1,2-phenyl-enebis(nitrilo-methanylyl-idene)]diphenolate dianion, and is further coordinated by a cyanide anion and a water mol-ecule in the axial sites, completing a distorted octa-hedral coordination geometry. In the crystal, pairs of bifurcated O-H⋯(O,O) hy...

We have studied the effect of N-bromoacetamide (NBA) on the behavior of single sodium channel currents in excised patches of rat myotube membrane at 10 degree C. Inward sodium currents were activated by voltage steps from holding potentials of about -100 mV to test potentials of -40 mV. The cytoplasmic-face solution was isotonic CsF. Application of NBA or pronase to the cytoplasmic face of the ...
