A novel mouse model of endometriosis: Simulating the recurrent hemorrhagic microenvironment of clinical lesions

open access: yesAnimal Models and Experimental Medicine, EarlyView.
To address the limitations of existing models, this study innovatively established a mouse model of endometriosis (EMs) capable of mimicking cyclic bleeding. Our results confirmed that this model recapitulates the complete pathological progression from ectopic lesion establishment to systemic responses, exhibiting superior clinical relevance compared ...

Catalytic Functionalization of Unactivated π‐Bonds Enabled by Bidentate Directing Auxiliaries

open access: yesAngewandte Chemie, EarlyView.
This review explores how bidentate directing auxiliaries have advanced transition‐metal catalysis for unactivated alkene/alkyne functionalization. By leveraging chelated intermediates, bidentate directing auxiliaries enable precise hydrofunctionalization, difunctionalization, and C─H activation of π‐bonds with unique selectivity and reactivity.

Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis

open access: yesAdvanced NanoBiomed Research, EarlyView.
Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...

Crosslinking of Linear Polyimines Into Aminal‐Linked Porous Organic Polymers for C2 Hydrocarbon/Methane Separation

open access: yesAngewandte Chemie, EarlyView.
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...
