Summary: The ability of P.aeruginosa biofilms to activate inflammasomes and increase inflammatory response contributes to chronic infection. This study found that P.aeruginosa biofilms significantly enhance the production of IL-1β and IL-18, possibly through the regulation of NLRP3 inflammasomes rather than NLRC4 inflammasomes.

Summary: This study investigated the role of phages in disrupting and inactivating clinical P. aeruginosa biofilms. Four previously isolated phages were effective in disrupting the formed biofilms at a multiplicity of infection (MOI) of 10. Phage treatments reduced the biofilms' biomass and led to the detachment of cells. The phages were also able to kill the cells from the biofilms, reducing the living cell counts.

Summary: Biofilm-related nosocomial infections can cause various life-threatening infections. In this study, hydroxyapatite nanoparticles (HANPs) were synthesized using a co-precipitation method followed by microwave treatment, and their ability to inhibit the biofilm formation of Pseudomonas aeruginosa ATCC 10145 was investigated. The results showed that the synthesized HANPs effectively inhibited biofilm formation, suggesting their potential use in controlling biofilm-related infections caused by Pseudomonas aeruginosa.

Summary: The research demonstrates that 3 wt% Eu3+ doped NiO exhibits a good response and sensitivity towards toluene at 100 degrees Celsius with 1 V bias voltage, along with a low detection limit. By precisely designing the relative amount of Eu3+ in NiO, the gas sensitivity and selectivity of the sensor can be further optimized.

Summary: The study focused on the development of novel cyclic dipeptide-carbohydrate conjugates as dual-functional QS inhibitors for treating Pseudomonas aeruginosa infections. These conjugates show enhanced anti-QS activity, good anti-biofilm and anti-adhesion abilities, and improve the germicidal efficiency of the clinical antibiotic azithromycin when used synergistically. This provides a new scaffold for developing antivirulence adjuvants when combined with clinical antibiotics.

Summary: Selective crystallization into metal-organic frameworks (MOFs) presents new opportunities for rare-earth separation. The development of MOF platforms with high selectivity toward target ions, such as the CPM-66 platform, shows exceptional ion-size selectivity during crystallization. This work provides insights into preparing low-coordinate MOFs for efficient lanthanide separation and other applications.

Summary: The anti-virulence potential and mechanism of Perilla frutescens-derived dihydrocuminyl aldehyde (DCA) against Pseudomonas aeruginosa XZ01 were investigated using transcriptome sequencing and metabolomics. DCA effectively reduced the production of virulence factors and disrupted biofilm formation. Mechanistically, DCA down-regulated quorum sensing-related genes, increased membrane permeability, and suppressed efflux systems, leading to heightened susceptibility to nisin and metabolic disorders.

Summary: The study demonstrates the potential of plant-derived compounds such as curcumin, baicalein, esculetin, and cinnamaldehyde in combination with ciprofloxacin as effective anti-biofilm agents against Pseudomonas aeruginosa. These combinations not only reduce the minimum biofilm inhibitory concentration (MBIC), but also modulate the metabolic pathways and quorum sensing gene expressions of P. aeruginosa.

Summary: Pseudomonas aeruginosa isolates collected from clinical samples were characterized for biofilm formation, antimicrobial resistance, and virulence genes. Strong biofilm producers exhibited higher virulence scores and a significant correlation between overall virulence score and biofilm formation was observed. ERIC-PCR genotyping revealed genetic diversity and potential for cross-colonization in P. aeruginosa infections.

Summary: Combining rare-earth ions with halide perovskites can produce interesting optical properties in the visible and NIR regions. In this study, RE3+ ions (RE: Nd, Ho, Er, Tm) were successfully introduced into Cs4Cd1-wMnwBi2Cl12 quadruple perovskites through a hydrothermal method. The materials exhibited characteristic emission of RE3+ in the red and NIR regions via constructing a Mn2+ energy bridge. The energy transfer processes and mechanism were confirmed, and an evolution process from direct to indirect band gaps was verified.

Summary: The study found that 1,4-butanesultone was the most effective sulfonation reagent for lignin, producing a sulfonated product with high molecular weight and sulfonic group content, enhancing dispersibility and improving dyeing rate. The sulfonation by 1,4-butanesultone can decrease the phenolic hydroxyl content of lignin, preventing the adsorption of the dispersant on fibers and reducing fiber staining during dyeing process.

Summary: Upgrading renewable lignocellulose into bulk chemicals and drop-in-fuels is an advanced approach to meet alternative energy demands. Photocatalytic lignocellulose conversion, or photobiorefining, plays a crucial role in boosting the economic and technical feasibility of biomass valorization. However, designing light-driven lignin deconstruction with photocatalytic selectivity and durability is still a challenging task.
