Genotoxic damage in buccal epithelial cells associated with mercury amalgam fillings

Toxicological & Environmental Chemistry
Mercury amalgam is a material that has long been used for dental restorations. Among its properties are its ease of handling, durability, low cost, clinical longevity and reduction of microleakage, compared to other dental materials.

Exploiting the higher specificity of silver amalgamation: selective detection of mercury(II) by forming Ag/Hg amalgam.

Analytical Chemistry, 2013
Heavy metal ion pollution poses severe risks in human health and the environment. Driven by the need to detect trace amounts of mercury, this article demonstrates, for the first time, that silver/mercury amalgamation, combining with DNA-protected silver ...

To Love and to Kill: Accurate and Selective Colorimetry for Both Chloride and Mercury Ions Regulated by Electro-Synthesized Oxidase-like SnTe Nanobelts.

Analytical Chemistry, 2021
Herein, SnTe nanobelts (NBs) with efficient oxidase-mimetic activity were synthesized by the simple electrochemical exfoliation method. A specific inhibition effect of Cl- on the enzymatic behavior of the pure SnTe NBs was discovered, which was ...

The amalgamation behavior of heavy elements—IV the tracer chemistry of divalent mendelevium

Journal of Inorganic and Nuclear Chemistry, 1969
Abstract In this paper it is shown that the extraction of medelevium into sodium amalgam from sodium acetate solutions results in about a ten fold enrichment relative to the lighter actinides (Pu, Am, Cm, Bk). Separation of Md from the heavier actinides may be accomplished by either of two methods: (1) an amalgam containing Md, Fm, Es, and Cf can be

Fabrication and characterization of solid mercury amalgam electrodes for protein analysis.

Analytical Chemistry, 2010
Gold and carbon electrodes have been largely used as transducers in protein and DNA sensors and arrays. Liquid mercury electrodes, with potential windows allowing detection of DNA and protein reduction processes at highly negative potentials, were ...

Comparing the Electronic Structure of Iron, Cobalt, and Nickel Compounds That Feature a Phosphine-Substituted Bis(imino)pyridine Chelate.

Inorganic Chemistry, 2022
It was recently discovered that (Ph2PPrPDI)Mn (PDI = pyridine diimine) exists as a superposition of low-spin Mn(II) that is supported by a PDI dianion and intermediate-spin Mn(II) that is antiferromagnetically coupled to a triplet PDI dianion, a finding ...

Label-free determination of picogram quantities of DNA by stripping voltammetry with solid copper amalgam or mercury electrodes in the presence of copper.

Analytical Chemistry, 2002
Highly sensitive label-free techniques of DNA determination are particularly interesting in relation to the present development of the DNA sensors. We show that subnanomolar concentrations (related to monomer content) of unlabeled DNA can be determined ...
