A Tailored Artificial Biocatalyst for Bacterial Endophthalmitis Therapy via Enhanced Ferroptosis‐Like Death

Advanced Science, EarlyView.
A tailored bio‐targeted catalytic strategy based on a bacteria‐specific artificial biocatalyst (MoS2/Fe@mercaptophenylboronic acid@hyaluronic acid, MFBH) is proposed for treating bacterial endophthalmitis. This strategy exhibits high‐efficiency peptidoglycan‐targeted bactericidal efficacy in vivo following a single intravitreal injection of an ...

Preliminary Study on Retinal Vascular and Oxygen-related Changes after Long-term Silicone Oil and Foldable Capsular Vitreous Body Tamponade

Scientific Reports, 2014
Silicone oil has been the only long-term vitreous substitute used in the treatment of retinal detachment since 1962 by Cibis. Nevertheless, its effects on retinal vascular morphology and oxygen supply to the retina are ambiguous in current research.

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

Advanced Science, EarlyView.
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is the key driver of ferroptosis. The authors discovered that PHOSPHO1 lowers the level of PE in retinal pigment epithelial cells thus reducing the formation of lipid peroxides. Lowering PE levels can also prevent the creation of autolysosomes, reduce the production of free iron ...

Magnetically Controllable and Degradable Milliscale Swimmers as Intraocular Drug Implants

Advanced Science, EarlyView.
Magnetically controllable degradable milliscale swimmers (MDMS) offer a promising alternative to commercial intraocular drug implants, reducing complications like implant dislocation and uncontrolled drug release. MDMS achieve high velocities in ocular environments, enable real‐time imaging, and deliver drugs effectively without disrupting retinal ...
