All‐in‐One Intelligent Hemostatic Sponge: Rapid Hemostasis for Non‐Compressive Wounds With Synergetic Enhanced Antibacterial Efficacy and Self‐Reporting Biodegradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Clinicians often concurrently tackle critical challenges including emergency hemorrhage, secondary infection, and the elusive tracking of biodegradation of conventional hemostatic agents for complex wounds. Here, we report an intelligent hemostatic sponge (spCS@AIE) by incorporating aggregation‐induced emission (AIE) nanoparticles with short‐wave ...

Expanding the Scope of 1,2‐Diazepines Through Alternative Activation Strategies

European Journal of Organic Chemistry, EarlyView.
Often overlooked due to tedious synthetic routes, 1,2‐diazepines can be found in handful of biorelevant molecules. Previous reports from our group lifted the principal synthetic lock: a rapid and user‐friendly protocol to reach monocyclic 1,2‐diazepines from readily available pyridines and electrophilic activating groups. Herein, we extend the scope of

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles

Food Bioengineering, EarlyView.
A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...

Spatially Resolved Metabolomics of Optimal Cutting Temperature (OCT) Compound‐Embedded Tumors

International Journal of Cancer, EarlyView.
ABSTRACT Mass spectrometry imaging (MSI) is emerging as a powerful tool for uncovering the distribution of metabolites in the tumor microenvironment and studying tumor metabolism in vivo. To date, MSI of biobanked tissues contextualized by patient data has been limited to peptides, proteins, and glycans—with few examples for metabolites.

Gold(I)‐Catalyzed Annulation of Pyridines Containing Alkyne: Synthesis of N‐Alkenyl Pyridonyl Azides via Rearrangement

Journal of Heterocyclic Chemistry, EarlyView.
One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...
