Diabetic wounds with chronic infections present a significant challenge, exacerbated by the growing issue of antimicrobial resistance, which often leads to delayed healing and increased morbidity. This study introduces a novel silver-zinc oxide-eugenol (Ag+ZnO+EU) nanocomposite, specifically designed to enhance antimicrobial activity and promote wound healing. The nanocomposite was thoroughly characterized using advanced analytical techniques, confirming its nanoscale structure, stability and chemical composition.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements.

Rifampicin-resistant tuberculosis (RR-TB) is a critical issue with significant implications for patient care, public health, and TB control efforts that necessitate comprehensive strategies for detection. This study presents a novel point-of-care diagnostic tool for RR-TB detection employing a peptide nucleic acid (PNA)-paper-based sensor combined with isothermal recombinase polymerase amplification (RPA). The sensor targets mutations in codons 516, 526, and 531 of the rpoB gene, the top three common mutations associated with rifampicin-resistant strains.

The management of bacterial wounds presents a significant challenge in the field of medicine and poses a grave threat to public health. Traditional gauze materials exhibit limited efficacy in treating bacterial infection wounds, while antibiotics demonstrate cytotoxicity and resistance. Therefore, in this study, the peptide biomimetic polymer (PAL-BA) was designed and served as the antibacterial framework for constructing an antibiotic drug-free antibacterial hydrogel dressing through a Schiff base reaction with oxidized hyaluronic acid (OHA).

Bacterial infections are a significant obstacle to the healing of acute and chronic wounds, such as diabetic ulcers and burn injuries. Traditional antibiotics are the primary treatment for bacterial infections, but they present issues such as antibiotic resistance, limited efficacy, and potential side effects. This challenge leads to the exploration of nanozymes as alternative therapeutic agents.
