Proinflammatory Epstein–Barr Virus Antibody Functions Track with Disease Activity in Multiple Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective Epstein–Barr virus (EBV) has been implicated in the pathogenesis of multiple sclerosis (MS). Elevated immunoglobulin G (IgG) titers against EBV nuclear antigen 1 (EBNA1) represent the most consistent serological marker of MS risk, with levels remaining persistently elevated following disease onset.

AND‐Logic‐Gated Aptamer Switch for Precise Targeting and Regulation of RNA G‐Quadruplexes

open access: yesAngewandte Chemie, EarlyView.
An AND‐logic‐gated aptamer switch enables tumor‐selective activation of RNA G‐quadruplex (rG4)‐targeting function. By combining cell‐surface recognition and intracellular redox sensing, the system achieves precise regulation of disease‐relevant RNA structures exclusively in tumor cells, with minimal off‐target effects in normal cells, offering a ...

Amidase‐Catalyzed Desorption of CO2 Captured in Aqueous Monoethanolamine (MEA) Solutions

open access: yesAngewandte Chemie, EarlyView.
CO2 is captured in aqueous monoethanolamine (MEA) sorbents as carbamate and bicarbonate/carbonate. The subsequent desorption for storage or utilization is energy‐intensive, and this is a major impediment to industrial carbon dioxide removal (CDR) processes. The desorption process can be promoted by enzymes that catalyze the dissociation of distinct CO2‐

1,7‐Digallatetracarborane: Between Nucleophilic closo‐Cluster and “Inverse Sandwich” Digallylene

open access: yesAngewandte Chemie, EarlyView.
A dianionic π‐ligand is used to make a Janus‐type twofold complex with low‐valent gallium Ga(+I). The resulting compound can be seen as and reveals the reactivity of both: a Wade‐type closo‐carborane cluster with nucleophilic Ga‐sites, as well as π‐ligand stabilized Ga(I) atoms in an inverse sandwich compound.

Uncovering Aggregation‐Induced Emission in Carbon Dots for Color‐Changing Hydrogels and Information Encryption

open access: yesAngewandte Chemie, EarlyView.
Red‐emissive carbon dots (R‐CDs) exhibiting aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) effects are synthesized from citric acid and urea. They display weak blue fluorescence in water but strong red emission in DMF due to aggregation.
