The emergence of multidrug-resistant (MDR) pathogens, coupled with the limited effectiveness of existing antibiotics in eradicating biofilms, presents a significant threat to global health care. This critical situation underscores the urgent need for the discovery and development of antimicrobial agents. Recently, peptide-derived antimicrobial nanomaterials have shown promise in combating such infections.

Covalent modification of cell membranes has shown promise for tumor imaging and therapy. However, existing membrane labeling techniques face challenges such as slow kinetics and poor selectivity for cancer cells, leading to off-target effects and suboptimal efficacy. Here, we present an enzyme-triggered self-immobilization labeling strategy, termed E-SIM, which enables rapid and selective labeling of tumor cell membranes with bioorthogonal trans-cycloctene (TCO) handles .

In the development of inflammatory bowel disease (IBD), peritoneal macrophages contribute to the resident intestinal macrophage pool. Previous studies have demonstrated that oral administration of L-fucose exerts an immunomodulatory effect and repolarizes the peritoneal macrophages in vivo in mice. In this study, we analyzed the phenotype and metabolic profile of the peritoneal macrophages from mice, as well as the effect of L-fucose on the metabolic and morphological characteristics of these macrophages in vitro.

Background: Widespread bacterial infection and the spread of multidrug resistance (MDR) exhibit increasing threats to the public and thus require new antibacterial strategies. Coupled with the current slow pace of antibiotic development, the use of antibiotic adjuvants to revitalize existing antibiotics offers great potential.
Purpose: We aim to explore the synergistic antimicrobial mechanism of glabrol (GLA) and colistin (COL) while developing an innovative multifunctional micelle-based drug delivery system to enhance therapeutic efficacy.
Mesothelial cell responses to acute appendicitis or small bowel obstruction reactive ascites: Insights into immunoregulation of abdominal adhesion.

Trauma Research, Swedish Medical Center, Englewood, Colorado, United States of America.
Previous abdominal surgery (PAS) increases risk of small bowel obstruction (SBO) due to adhesions, and appendectomy (appy) is an independent risk factor for abdominal adhesion-related complications. Peritoneal inflammation, e.g.
