A Cytoplasmic pH Sensor Redefines Gating in Bacterial Urea Channels and Acid Resistance

open access: yesSmall, EarlyView.
Bacterial survival in acidic environments requires pH‐gated urea channels. Utilizing complementary approaches, we identify a conserved cytoplasmic glutamic acid residue as a pH sensor in UreI channels. Whereas Gram‐positive bacteria rely solely on this sensor, Gram‐negative bacteria employ a dual‐sensor mechanism with periplasmic residues, revealing a ...

Revisiting small‐molecule fluorescent probes in food freshness detection

open access: yesSmart Molecules, EarlyView.
Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Evaluating Thiram‐Induced Embryotoxicity Using Integrated In Silico, In Vitro, and Transcriptomic Approaches

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Long‐term exposure to low‐dose food contact materials (FCMs) has raised concerns regarding developmental toxicity. In the present study, we prioritized FCMs with potential developmental toxicity using a weight‐of‐evidence computational model, which predicted 127 chemicals to be of high concern.
