Combining aptamers for thiamphenicol and chloramphenicol for detecting both antibiotics.
Chemical CommunicationsA DNA aptamer named TAP-1 for thiamphenicol (TAP) was selected using the capture-systematic evolution of ligands by exponential enrichment (SELEX) technique, exhibiting a dissociation constant (Kd) of 6.4 μM as determined by isothermal titration ...

Molecular Microbiology, Volume 126, Issue 1, Page 98-110, July 2026.Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.Kinetic resolution by copper hydride catalyzed reduction of 2H‐azirines secured optically enriched N‐H aziridine‐2‐carboxylates with excellent diastereoselectivity (>20:1) and good enantioselectivity (up to 94% ee). DFT calculations and non‐covalent interaction analysis established the reaction pathway and revealed two key non‐covalent interactions ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Environmental Microbiology, Volume 28, Issue 6, June 2026.In reservoir‐associated RT033 strains, we observe a natural rewiring of spore germination that lowers the activation threshold and broadens bile‐salt specificity, enabling germination at low germinant levels and in response to typically inhibitory bile‐salts common in animal hosts.
