A multifunctional platform based on two-dimensional nanomaterials for combined antibacterial and anti-inflammatory therapy is developed. Bi2Se3 nanodiscs selectively eradicate Gram-positive bacteria with a low risk of drug resistance. Moreover, Bi2Se3 nanodiscs with antioxidant activity relieve intracellular oxidative stress of macrophages to suppress inflammation caused by bacterial infections.

The emergence of multidrug-resistant pathogens presents a significant global health challenge, which is primarily fuelled by overuse and misuse of antibiotics. Bacteria-derived antimicrobial metabolites offer a promising alternative strategy for combating antimicrobial resistance issues. Bacillus velezensis PD9 (BvPD9), isolated from stingless bee propolis, has been reported to have antibacterial activities against methicillin-resistant Staphylococcus aureus (MRSA).

In this study, we evaluated the combined effect between MLE-15, a modular lytic enzyme composed of four building blocks, and reline, a natural deep eutectic solvent. The bioinformatic analysis allowed us to determine the spatial architecture of MLE-15, whose components were bactericidal peptide cecropin A connected via a flexible linker to the cell wall binding domain (CBD) of mesophilic 201ϕ2 - 1 endolysin and catalytic domain (EAD) of highly thermostable Ph2119 endolysin. The modular enzyme showed high thermostability with the melting temperature of 93.

Nano-TiO as an antimicrobial inorganic material, can stimulate cells to produce reactive oxygen species and exhibit effective biochemical properties; however, phenylpyrazole derivatives, as organic pesticides, are widely used in agriculture and food. To find novel pesticides with environmental friendliness, combined with three-dimensional quantitative structure-activity relationship (3D-QSAR) prediction analysis, three types of alkaloidal phenylpyrazole amine derivatives (PA) were synthesized by a one-pot microwave method. Based on the dye sensitization strategy, four nano-organometallic pesticides (PT) were prepared by organic-inorganic hybridization.

Biofilm formation, extracellular substance synthesis, and virulence factor production all have a major impact on drug tolerance and infection propagation caused by Staphylococcus aureus. Flavonoid compounds have been explored as potential solutions to enhance antibiotic efficacy against the biofilm formation of pathogenic microbes. Quercetin (QER) has previously demonstrated antibacterial and antibiofilm properties.

Objective: To evaluate the available evidence comparing the use of the bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) regimen for 6 months with that of standard-of-care regimens for patients with multidrug-resistant or rifampin-resistant tuberculosis (MDR/RR-TB).
Methods: This was a systematic review of clinical trials comparing the use of the BPaLM regimen with the standard of care in patients with MDR/RR-TB. The main outcome measure was an unfavorable endpoint (a composite of death, treatment failure, treatment discontinuation, loss to follow-up, and recurrence), and secondary outcome measures included adverse events and serious adverse events.
