Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The 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.

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

Environmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the
