PMID: 27671769
Sci Rep. 2016 Sep 27;6:34024. doi: 10.1038/srep34024.

A series of novel hexadentate enterobactin analogues, which contain three catechol chelating moieties attached to different molecular scaffolds with flexible alkyl chain lengths, were prepared. The solution thermodynamic stabilities of the complexes with uranyl, ferric(III), and zinc(II) ions were...

PMID: 26977427
Data Brief. 2015 Dec 31;6:461-5. doi: 10.1016/j.dib.2015.12.028. eCollection 2016 Mar.

In this data article we have provided evidence for the negative influence of divalent cations on (-)-epigallocatechin-3-gallate (EGCG)-mediated inhibition of matrix metalloproteinase-2 (MMP-2) activity in cell-free experiments. Chelating agents, such as EDTA and sodium citrate alone, did not affect...

Determination of elemental composition of metals using ambient organic mass spectrometry.

Anal Chim Acta. 2017 May 22;968:50-57. doi: 10.1016/j.aca.2017.03.009. Epub 2017 Mar 24.

Conventional inorganic mass spectrometric (MS) analysis of metals can require time-consuming and tedious sample preparation. We thus report the novel and direct characterization of metals in solid samples using an organic MS technique known as electrospray laser desorption ionization...

Chelation for autism spectrum disorder (ASD).

The Cochrane database of systematic reviews

James S, Stevenson SW, Silove N, Williams K.
PMID: 26114777
Cochrane Database Syst Rev. 2015 May 11;5:CD010766. doi: 10.1002/14651858.CD010766.pub2. Epub 2015 May 11.

BACKGROUND: It has been suggested that the severity of autism spectrum disorder (ASD) symptoms is positively correlated with the level of circulating or stored toxic metals, and that excretion of these heavy metals, brought about by the use of...

Effect of Chelating Agents on the Stability of Nano-TiO2 Sol Particles for Sol-Gel Coating.

Journal of nanoscience and nanotechnology

Maeng WY, Yoo M.
PMID: 26726529
J Nanosci Nanotechnol. 2015 Nov;15(11):8429-33. doi: 10.1166/jnn.2015.11462.

Agglomeration of sol particles in a titanium alkoxide (tetrabutyl orthotitanate (TBOT), > 97%) solution during the hydrolysis and condensation steps makes the sol solution difficult to use for synthesizing homogeneous sol-gel coating. Here, we have investigated the effect of...

Electrospray ionization mass spectrometry for the quantification of inorganic cations and anions.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry

Hotta H, Tsunoda K.
PMID: 25792268
Anal Sci. 2015;31(1):7-14. doi: 10.2116/analsci.31.7.

Recent studies from our laboratory on electrospray ionization mass spectrometry (ESI-MS) for the quantification of inorganic cations and anions are reviewed. Metal ions were determined by ESI-MS in negative-ion mode as monovalent negative ions of their aminopolycarboxylate (APC) complexes,...

Enhancement effects of chelating agents on the degradation of tetrachloroethene in Fe(III) catalyzed percarbonate system.

Chemical engineering journal (Lausanne, Switzerland : 1996)

Miao Z, Gu X, Lu S, Brusseau ML, Zhang X, Fu X, Danish M, Qiu Z, Sui Q.
PMID: 26549979
Chem Eng J. 2015 Dec 01;281:286-294. doi: 10.1016/j.cej.2015.06.076. Epub 2015 Jun 23.

The performance of Fe(III)-based catalyzed sodium percarbonate (SPC) for stimulating the oxidation of tetrachloroethene (PCE) for groundwater remediation applications was investigated. The chelating agents citric acid monohydrate (CIT), oxalic acid (OA), and Glutamic acid (Glu) significantly enhanced the degradation...

What do Cochrane systematic reviews say about interventions for autism spectrum disorders?.

Sao Paulo medical journal = Revista paulista de medicina

Lyra L, Rizzo LE, Sunahara CS, Pachito DV, Latorraca COC, Martimbianco ALC, Riera R.
PMID: 28538871
Sao Paulo Med J. 2017 Mar-Apr;135(2):192-201. doi: 10.1590/1516-3180.2017.0058200317.

CONTEXT AND OBJECTIVE:: Autism spectrum disorders (ASDs) include autistic disorder, Asperger's disorder and pervasive developmental disorder. The manifestations of ASDs can have an important impact on learning and social functioning that may persist during adulthood. The aim here was...

Detection of Metal and Organometallic Compounds with Bioluminescent Bacterial Bioassays.

Advances in biochemical engineering/biotechnology

Durand MJ, Hua A, Jouanneau S, Cregut M, Thouand G.
PMID: 26475470
Adv Biochem Eng Biotechnol. 2015 Oct 17; doi: 10.1007/10_2015_332. Epub 2015 Oct 17.

Chemical detection of metal and organometallic compounds is very specific and sensitive, but these techniques are time consuming and expensive. Although these techniques provide information about the concentrations of compounds, they fail to inform us about the toxicity of...
