Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

FEBS Open Bio, EarlyView.
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.

Research progress on the metabolic transformation of Shenling Baizhu San under the influence of the gut microbiota

Advanced Chinese Medicine, EarlyView.
Abstract The gut microbiota plays a pivotal role in maintaining host metabolic homeostasis and overall physiological functions. Shenling Baizhu San (SLBZS), a time‐honored classical prescription for tonifying Qi, strengthening the spleen, removing dampness, and arresting diarrhea, has shown broad clinical efficacy in digestive disorders.
