Background: Pseudomonas aeruginosa's inherent and adapted resistance makes this pathogen a serious problem for antimicrobial treatments. Furthermore, its biofilm formation ability is the most critical armor against antimicrobial therapy, and the virulence factors, on the other hand, contribute to fatal infection and other recalcitrant phenotypic characteristics. These capabilities are harmonized through cell-cell communication called Quorum Sensing (QS), which results in gene expression regulation via three major interconnected circuits: las, rhl, and pqs system.

Chronic itch in older patients is a common problem, with a significant impact on quality of life. Chronic itch in the older population may be attributable to several causes, such as age-related changes, skin conditions, systemic conditions, medications, and psychological conditions. Given the complexity of itch in this population, comorbidities, and polypharmacy in most geriatric patients, treating chronic itch can be challenging for healthcare providers.

Invasive pneumococcal disease (IPD) is a serious global public health problem and the leading cause of morbidity and mortality in children and adults in China. Thus, developing and administering pneumococcal vaccines are important for disease prevention. The PPV23 and PCV13 vaccines are available in the Chinese market and are primarily produced by domestic manufacturers.

Uncorrected refractive error is a key cause of childhood visual impairment in the United States. As pediatric vision issues are often asymptomatic, vision screenings are essential to identify children's eye problems. Despite the importance of vision for children's health, well-being, and academic achievement, challenges remain in ensuring that children have equitable access to vision screenings and follow-up eye care.

Cell-interface engineering is a way to functionalize cells through direct or indirect self-assembly of functional materials around the cells, showing an enhancement to cell functions. Among the materials used in cell-interface engineering, natural biomolecules play pivotal roles in the study of biological interfaces, given that they have good advantages such as biocompatibility and rich functional groups. In this review, we summarize and overview the development of studies of natural biomolecules that have been used in cell-biointerface engineering and then review the five main types of biomolecules used in constructing biointerfaces, namely DNA polymers, amino acids, polyphenols, proteins and polysaccharides, to show their applications in green energy, biocatalysis, cell therapy and environmental protection and remediation.
