A Review on Kinematically Redundant Parallel Mechanisms With Configurable Platforms

open access: yesSmartBot, Volume 1, Issue 4, December 2025.
This review systematically combs the development context and technical system of Parallel Mechanisms with Configurable Platforms (PMCPs). Furthermore, through the progressive logic of classification, analysis and application, the paper reveals how “kinematic redundancy” and “configurable platform” break through the rigid limitations of traditional ...

Macrophages Internalize Epithelial‐Derived Extracellular Vesicles That Contain Ferritin via the Macrophage Scavenger Receptor 1 to Promote Inflammatory Bowel Disease

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 6, June 2025.
This study explores the interaction between intestinal epithelial cells (IECs) and macrophages through extracellular vesicles (EVs) in the context of inflammatory bowel disease (IBD). IECs release iron‐loaded ferritin via EVs as the donor, while macrophage scavenger receptor 1 on the surface of macrophages serves as the receptor for the internalization

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

open access: yesFEBS Open Bio, Volume 15, Issue 5, Page 773-792, May 2025.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.
