An Instrument for Isomer‐Specific Action Spectroscopy of Charged Clusters: Electronic Spectra of C 14 + and Ca@C 60 +

Chemistry–Methods, Volume 6, Issue 8, August 2026.
Disentangling spectral congestion of a mixture of isomers in gas‐phase spectroscopy is critical. We present an instrument combining ion mobility, mass spectrometry, and spectroscopy in a cryogenic 3D Paul trap to investigate the isomer‐specific charged clusters and illustrate its performance with the electronic spectra of C14+ and Ca@C60+.

Liquid Chromatography–Tandem Mass Spectrometry Quantification of Diet‐Derived CYP2D6 Biomarkers for Clinical Phenotyping in Japanese Subjects

Clinical and Translational Science, Volume 19, Issue 8, August 2026.
ABSTRACT The enzymatic activity of cytochrome P450 2D6 (CYP2D6) exhibits substantial interindividual variation, which influences drug efficacy and the risk of adverse drug reactions to various therapeutics. While current protocols for CYP2D6 genotyping or CYP2D6 phenotyping provide useful information, less invasive and simpler tools are desirable for ...

Beyond Sequence: Posttranslational Remodeling of Antigens in Autoimmunity

Immunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT Autoimmune responses are often attributed to failed tolerance to self‐proteins, yet protein expression alone cannot explain why certain antigens dominate disease, why autoreactivity emerges under stress, or why specific HLA alleles shape risk.
