The content of lipid peroxidation products (malonic dialdehyde) in the aqueous humor is increased in patients with mature cataracts developing after antiglaucoma surgery. Antioxidative activity of the humor was decreased. A relationship was revealed between the postoperative changes in ocular hydrodynamics and metabolic disorders in the chamber humor (reduction of the antioxidative activity of the humor and its suppressed production), which explains one mechanism of cataract development in patients operated on for glaucoma.

Cerebral ischemic stroke, neuronal death, and inflammation bring difficulties in neuroprotection and rehabilitation. In this study, we developed and designed the ability of natural lactoferrin-polyethylene glycol-polyphenylalanine-baicalein nanomicelles (LF-PEG-PPhe-Bai) to target and reduce these pathological processes, such as neurological damage and cognitive impairment in the stages of poststroke. Nanomicelles made from biocompatible materials have improved bioavailability and targeted distribution to afflicted brain areas.

Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism.

Aspartate (Asp) metabolism-mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis.
