Extractability and mobility of mercury from agricultural soils surrounding industrial and mining contaminated areas [PDF]

open access: yes, 2010
This study focussed on a comparison of the extractability of mercury in soils with two different contamination sources (a chlor-alkali plant and mining activities) and on the evaluation of the influence of specific soil properties on the behaviour of the

50 Years of Giese Reaction – a Personal View

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
The Giese‐Reaction celebrates its 50. Birthday, it is a cyclic radical chain reaction centered around C,C‐bond formation in a three component synthesis. This minireview speaks about the birth of the name‐reaction, explains how the complete understanding of its reaction mechanism stimulates new methods in organic synthesis, and why it can proceed in ...

Histone lactylation bridges metabolic reprogramming and epigenetic rewiring in driving carcinogenesis: Oncometabolite fuels oncogenic transcription. [PDF]

open access: yesClin Transl Med
The lactate‐induced lactylation of histone lysine residues bridges the metabolic reprogramming and epigenetic rewiring. Histone lactylation fuels oncogene overexpression, expediting tumour progression and development. Targeting lactate signalling exhibits with therapeutic efficacy in diversified cancers. Abstract Heightened lactate production in cancer

Analytical methods for mercury speciation in several matrixes: a review [PDF]

open access: yes, 2008
Mercury is one of the hazardous contaminants that may be present in the environment. Moreover, its toxicological effects are strongly dependent on the chemical form of the element, being the organic species the most toxic.

5,7‐Membered Cyclometallated Gold(III) Complexes with Pyridine‐Phenyl‐Oxazoline N^C^N Ligands as Catalysts for Organic Transformation Reactions Under Silver‐Free Conditions

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 17, September 26, 2025.
A series of 5,7‐membered cyclometallated gold(III) complexes with N^C^N tridentate ligands are prepared via transmetalation of pyridine‐phenyl‐oxazoline ligand‐containing organomercury compounds with potassium gold(III) chloride (KAuCl4) for catalysis.

Pigments Induced by Organomercurial Compounds in Cephalosporium diospyri [PDF]

open access: yesJournal of General Microbiology, 1974
Summary: The major pigments induced by parahydroxymercuribenzoate and parachloromercuribenzoate (both SH group inhibitors) in the fungus Cephalosporium diospyri have been characterized as carotenoids. Those present in both chemically-induced and light-induced cells include phytoene, β-carotene, γ-carotene, lycopene, torulene and neurosporaxanthin.

Covalently Mercurated 6‐Phenylcarbazole Residues Promote Hybridization of Triplex‐Forming Oligonucleotides

open access: yesChemBioChem, Volume 26, Issue 8, April 14, 2025.
Organomercury derivatives of 6‐phenylcarbazole can stabilize triple helices when placed at the termini of triplex‐forming homothymine oligonucleotides. In some cases, this stabilization could be attributed to direct coordination of a Hg(II) ion to adenine‐N7 or cytosine‐N4.

Mercury methylation versus demethylation: main processes involved [PDF]

open access: yes, 2011
It is well known that mercury presents high toxicity, causing a great damage to the environment and living organisms; however, its properties depend on the mercury species present.
