Background: A blood-based approach to monitor metastasis and recurrence of esophageal squamous cell carcinoma (ESCC) remains undeveloped. This study aimed to establish a dependable model utilizing cfDNA 5-hydroxymethylcytosines (5hmC) signatures to detect these conditions in ESCC.
Methods: The 5hmC-Seal technique was employed to generate comprehensive 5hmC profiles from the plasma cell-free DNA (cfDNA) of 122 ESCC patients, classified into 72 with metastasis, 50 without metastasis, 30 with recurrence, and 92 without recurrence.
Fungal keratitis is a vision-threatening corneal infectious disease. However, clinically therapeutic medicines cannot attain ideal efficacy due to limited control of fungal virulence and excessive inflammatory response. Carnosic acid (CA) is a phenolic diterpene, which has been reported to have multiple abilities including antibacterial, anti-inflammatory and antioxidant.

However, photocatalytic performance is often limited by complex electron-nuclear interactions and strong exciton binding energies, primarily due to significant exciton effects. In this work, we introduce a novel strategy to enhance exciton dissociation by doping samarium (Sm) into bismuth oxoiodide (BiOI) to modulate the concentration of oxygen vacancies (Ov).

Ciprofloxacin, a third-generation quinolone antibiotic, is used to treat different types of bacterial infections; however, it often results in the rapid emergence of resistance in clinical settings. Inspired by low susceptibility to antimicrobial resistance of natural antimicrobial peptides, we herein propose a host defense peptide-mimicking strategy for designing chimeric quinolone derivatives which may reduce the likelihood of antibacterial resistance.

This study aimed to explore the role and potential mechanisms of liver X receptor α (LXRα) in CAVD, which offers a promising approach for treating CAVD.
Methods And Results: Osteogenic stimulation was performed following which a substantial downregulation of LXRα was observed in human calcific aortic valves and in valvular interstitial cells.
