Journal ArticleDOI
Characterization of human circulating TIG2 as a ligand for the orphan receptor ChemR23.
W. Meder,M. Wendland,A. Busmann,C. Kutzleb,N. Spodsberg,Harald John,Rudolf Richter,D. Schleuder,Markus Meyer,Wolf-Georg Forssmann +9 more
TL;DR: By means of reverse pharmacology screening using a peptide library generated from human hemofiltrate, TIG2 is isolated and identified as the natural ligand of ChemR23 and report the specific molecular form of the bioactive, circulating Tig2, representing the amino‐acid residues 21 to 154 of the 163 amino acid‐containing prepropeptide.
Journal ArticleDOI
Analytical procedures for quantification of peptides in pharmaceutical research by liquid chromatography–mass spectrometry
TL;DR: Procedures based on LC–MS techniques for quantitative determination of peptides are reviewed using numerous examples from the literature, complemented by experiments and results from the laboratory.
Journal ArticleDOI
Fatal sarin poisoning in Syria 2013: forensic verification within an international laboratory network.
Harald John,Marcel J. van der Schans,Marianne Koller,Helma E.T. Spruit,Franz Worek,Horst Thiermann,Daan Noort +6 more
TL;DR: Experimental results provided unambiguous evidence for a systemic intoxication and were the first proving the use of sarin in the ongoing bellicose conflict, highlighting the requirement for qualified and specialized analytical laboratories to face repeated violation of the Chemical Weapons Convention.
Journal ArticleDOI
LC-MS-based procedures for monitoring of toxic organophosphorus compounds and verification of pesticide and nerve agent poisoning
TL;DR: LC-MS-MS detection of phosphylated peptides generated from inhibited circulating serum butyrylcholinesterase by valuable proteomics techniques enables proof of intoxication on the molecular level, and a comprehensive overview on the status quo of LC- MS-based OPC analysis is given.
Journal ArticleDOI
A role for solvents in the toxicity of agricultural organophosphorus pesticides
Michael Eddleston,Jonathan M. Street,Ian Self,Adrian Thompson,Tim King,Nicola Williams,Gregorio Naredo,Kosala N. Dissanayake,Ly-Mee Yu,Franz Worek,Harald John,Sionagh Smith,Horst Thiermann,John Harris,R Eddie Clutton +14 more
TL;DR: Results indicate that solvents play a crucial role in dimethoate toxicity and reformulation of OP insecticides to ensure that the agricultural product has lower mammalian toxicity could result in fewer deaths after suicidal ingestion and rapidly reduce global suicide rates.
