Bio‐Propelled Stomatocyte Nanomotors with Glutathione‐Responsiveness for Osteoarthritis Treatment

open access: yesAngewandte Chemie, EarlyView.
Glutathione (GSH)‐responsive stomatocyte nanomotors with encapsulated MTX utilize oxygen to achieve autonomous motion and undergo GSH‐induced dissociation, enhancing cellular uptake, tissue penetration, and MTX release within the osteoarthritis (OA) region, thereby improving therapeutic efficacy.

The Herfindahl neutral point: A firm‐level threshold for managing market concentration with evidence from US hog packing

At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.
