Arctic plasmidome analysis reveals distinct relationships among associated antimicrobial resistance genes and virulence genes along anthropogenic gradients

Global Change Biology, Volume 30, Issue 5, May 2024.
We investigated the impact of melting glaciers and wastewater in the Arctic on the aquatic resistome. Plasmids, small genetic carriers known for transferring antibiotic resistance genes among bacteria were our target. By studying these genetic elements in glacial ice and nearby waters of Svalbard, we uncovered the presence of the unique as well ...

Organomercury Bioconjugate Synthesis and Characterization by Matrix-Assisted Laser Desorption Ionization Mass Spectrometry

, 2003
Synthesis of an organomercury hapten and conjugation of the hapten to proteins and peptides is described. Starting with allylamine, synthesis of the organomercury hapten was completed in five steps using readily available and inexpensive reagents.

Bioluminescence biosensor for the detection of organomercury contamination

, 2014
To selectively detect organomercurial compounds in the environment, in this study a bioluminescence biosensor for organomercurials was developed using a bacterial gene expression system for the mercury resistance determinant. merB(3)-Luciferase (mer-lux)

Sensitive, simultaneous determination of organomercury, -lead, and -tin compounds with headspace solid phase microextraction capillary gas chromatography combined with inductively coupled plasma mass spectrometry

, 1997
The use of the solid phase microextraction (SPME) technique for the simultaneous determination of organomercury, -tin, and -lead is described. The organometallic compounds were in situ derivatized with sodium tetraethylborate, sorbed on a poly ...

Multinuclear magnetic resonance study of organomercury fulminates. The structure of mercury fulminate in solution

, 1984
1H, 13C, 14N and 199Hg NMR data were obtained for organomercury fulminates, RHgCNO (R Me, Ph, CNO). The relatively slow relaxation processes effective for the quadrupolar nitrogen muclei of these compounds allow the detection of 199Hg14N scalar coupling

Synthesis and characterization of N,N ',C-bound organotellurium(IV) and organomercury(II) derivatives

, 2018
We report the synthesis and characterization of the first examples of organotellurium (IV)/organomercury(II) derivatives of N,N',C-chelating aryldiamine ligand, 2-{Me2NCH2CH2N(Me)CH2}C6H4Br (20). The dichalcogenides, [2-{Me2NCH2CH2N(Me)CH2}C6H4Se](2) (24)
