Sequential Recovery of Heavy and Noble Metals by Mussel-Inspired Polydopamine-Polyethyleneimine Conjugated Polyurethane Composite Bearing Dithiocarbamate Moieties

Polymers, 2019
Dithiocarbamate-grafted polyurethane (PU) composites were synthesized by anchoring dithiocarbamate (DTC) as a chelating agent to the polyethyleneimine-polydopamine (PE-DA)-functionalized graphene-based PU matrix (PE-DA@GB@PU), as a new adsorbent material

The 2024 European Union report on pesticide residues in food

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract Under European Union legislation (Article 32, Regulation (EC) No 396/2005), the European Food Safety Authority publishes an annual report assessing pesticide residue levels in food. In 2024, 9842 samples were analysed as part of the EU‐coordinated multiannual control programme subset, of which 1.2% were found to be non‐compliant.

Preclinical Evaluation of the Safety of the Dedicated Gel for Gel Immersion Endoscopy With Gastrointestinal Perforation and Peritoneal Leakage

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel immersion endoscopic mucosal resection or endoscopic submucosal dissection has been developed as an alternative to saline immersion therapeutic endoscopy. However, in cases of gastrointestinal perforation, gel may leak from the lumen into the peritoneal cavity, and the safety of such events remains unclarified.

Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

Food Safety and Health, Volume 4, Issue 2, Page 359-373, April 2026.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,

Regulation of nitric oxide signaling by formation of a distal receptor-ligand complex. [PDF]

, 2017
The binding of nitric oxide (NO) to the heme cofactor of heme-nitric oxide/oxygen binding (H-NOX) proteins can lead to the dissociation of the heme-ligating histidine residue and yield a five-coordinate nitrosyl complex, an important step for NO ...

Bis[N-2-hydroxyethyl,N-methyldithiocarbamato-κ2S,S)'-4-{[(pyridin-4-ylmethylidene)hydrazinylidene}methyl]pyridine-κN1)zinc(II): crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
In the title compound, [Zn(C4H8NOS2)2(C12H10N4)], the ZnII atom exists within a NS4 donor set defined by two chelating dithiocarbamate ligands and a pyridyl-N atom derived from a terminally bound 4-pyridinealdazine ligand.
