The N‐Bromo‐Hammick Intermediate

open access: yesChemistry – A European Journal, EarlyView.
Spectroscopic and computational analysis uncovers the σ2σ*0 electronic structure of the N‐bromo‐Hammick intermediate, a singlet N‐heterocyclic carbene isolated in solid neon, whose back‐isomerization to bromopyridine proceeds via a planar transition state.

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Tryptophan derivatives as non‐invasive diagnostic indicators for obesity‐related MASLD in children and adolescents

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Metabolic dysfunction‐associated steatotic liver disease (MASLD) represents a major health burden in children and adolescents with obesity. This study aimed to characterize metabolic alterations associated with obesity‐related MASLD and to evaluate the potential of tryptophan (TRP)‐derived metabolites as non‐invasive biomarkers for early ...
