Thirty three patients with rheumatoid arthritis (RA) treated only with non-steroidal anti-inflammatory drugs were divided into two groups according to the drug received (group A: diclofenac, group B: indomethacin or ketoprofen), and their polymorphonuclear (PMN) cell functions were investigated. We found that bactericidal ability was the only function significantly impaired in group A as compared with group B patients and normal controls. This modification correlated well with the reduction of control PMN bactericidal ability when this test was carried out in patient plasma. These differences between drug effects might explain some of the discrepancies between reports of PMN cell functions in RA.

Biological fouling seriously jeopardizes the development of the marine industry. Although hydrogels, as a kind of state-of-the-art antifouling material, have received wide attention, their mechanical strength is still relatively weak, and the synergistic antifouling method is comparatively single, thus limiting the performance of hydrogels. Here, a zwitterionic sulfobetaine methacrylate (SBMA)-acrylamide (AM)/sodium alginate (SA) double-network (DN) antifouling hydrogel with superb antifouling ability and outstanding mechanical properties was prepared by grafting MXene/Ag (M/Ag) and the powerful biocide polyhexamethylene biguanide (PHMB).

Multidrug-resistant (MDR) bacteria and their associated biofilms are major causative factors in eye infections, often resulting in blindness and presenting considerable global health challenges. Presently, mechano-bactericidal systems, which combine distinct topological geometries with mechanical forces to physically induce bacterial apoptosis, show promising potential. However, the physical interaction process between current mechano-bactericidal systems and bacteria is generally based on passive diffusion or Brownian motion and lacks the force required for biofilm penetration; thus, featuring low antibacterial efficacy.

Controlling microbial pollutants is a significant public health concern as they cause several chronic microbial infections and illnesses. In recent years, essential oils (EOs) have become intriguing alternatives for synthetic antimicrobials due to their biodegradability, natural source extraction, and strong antibacterial properties. The bactericidal properties of alginate containing lemon essential oil were examined in this investigation.

Pitting corrosion caused by sulfate-reducing bacteria (SRB) significantly shortens the lifespan of metallic pipelines. Antibacterial coatings containing S-responsive drug-loaded nanocontainers represent a promising method to mitigate SRB corrosion. However, the challenge of balancing rapid bactericide release with continuous antibacterial effect limits their practical application.

Hydrogels possessing appropriate adhesion and antibacterial properties have emerged as promising dressings for expediting wound healing, while also providing the convenience of visualizing the wound site to accurately monitor the healing process. In this study, we incorporated oxidized and degraded polydopamine nanoparticles into quaternized chitosan/oxidized dextran hydrogel QOP series, resulting in enhanced transmittance exceeding 95 % and adhesion strengths reaching up to 19.4 kPa.
