The discovery of acatalasemia (lack of catalase in the blood) and its significance in human genetics

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
Catalase, a heme-containing antioxidant enzyme, was once considered essential for human survival. It is widely distributed in the human body and is particularly abundant in red blood cells. The term “acatalasemia” first appeared in the Proceedings of the

Disease‐Stage Synchronized Nanozyme Therapy for Polymicrobial Sepsis through Adaptive Catalytic and Immune Reprogramming

Advanced Science, EarlyView.
A disease‐stage synchronized nanozyme platform is developed to treat polymicrobial sepsis by adapting its functions to changing infection environments. The system eliminates multidrug‐resistant bacteria during early infection while reducing inflammation and restoring immune balance during recovery, providing an integrated strategy for infection control

Accumulation of cuprum and cadmium and their effects on the antioxidant enzymes in Boettcherisca peregrina exposed to cuprum and cadmium

浙江大学学报. 农业与生命科学版, 2006
In Boettcherisca peregrina, changes in the activities of three species of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) were measured together with patterns of cuprum or cadmium accumulation as the newly ...

TH17–Associated Polyamine Metabolism‐Guided Nanozyme Promotes Alveolar Bone Repair in Periodontitis

Advanced Science, EarlyView.
A pronounced TH17‐skewed immune response is identified in experimental periodontitis, and enrichment of the polyamine pathway is observed during TH17 differentiation, suggesting its potential as an immunometabolic target. Inspired by these findings, DFMO@Ui‐Mn is developed as a therapeutic platform combining cascade ROS scavenging with immunometabolic ...
