Polyaniline has been utilized in various applications, yet its widespread adoption often impeded by challenges. Composite systems have proposed as a means of mitigating some these limitations, and anthranilic acid (2-aminobenzoic acid) emerged possible moderator for use co-polymer systems. It offers improved solubility retention electroactivity neutral alkaline media, and, significantly, it can also bestow chemical functionality through carboxylic substituent, which greatly ease post-polymer modification. The benefits using (as homopolymer or copolymer) demonstrated applications including corrosion protection, memory devices, photovoltaics, biosensors. Moreover, this polymer used versatile framework the sequestration metal ions water treatment, critically, same mechanisms serve facile route production catalytic metallic nanoparticles. However, polyanthranilic limited, aim present narrative review is to revisit early promise assess potential future within modern smart materials. A critical evaluation properties presented, versatility both monomer across spectrum highlighted.

Pseudomonas aeruginosa is an opportunistic pathogen that requires iron to survive in the host; however, host immune system limits availability of iron. Pyochelin (PCH) a major siderophore produced by P. during infection, which can help iron-restricted environment and cause infection. The infection activity regulated quinolone signal (PQS) quorum-sensing system. uses 2-heptyl-3-hydroxy-4-quinolone or its precursor, 2-heptyl-4-quinolone (HHQ), as molecule. PQS control specific life processes such mediating quorum sensing, cytotoxicity, acquisition. This review summarizes biosynthesis PCH PQS, shared transport regulatory relationship between PQS. correlation emphasized provide new direction for future research.

Stroke, as a serious cerebral vascular disease with high incidence and rates of disability mortality, has limited therapeutic options due to the narrow time window. Compelling evidence highlighted significance gut microbiota gut-brain axis critical regulatory factors affecting stroke. Along microbiota-gut-brain axis, tryptophan metabolism further acquires increasing attention for its intimate association central nervous system diseases. For purpose exploring potential role in stroke providing systematic insights into intricate connection pathological procedure stroke, this review first summarized practical relationship between by compiling latest case-control research. Then, well interaction were comprehensively elucidated on basis basic anatomical structure physiological function. Based crosstalk microbiota-gut-brain, we focused from three major metabolic pathways, namely, kynurenine pathway, serotonin microbial within axis. Moreover, effects appreciated elaborated here, which is scarcely found other reviews. Hopefully, illustration mechanisms pathways along will inspire more translational research perspectives, paid promising pharmaceutical target order reduce risk mitigate progression, ameliorate prognosis.
