Protective effects of free radical scavengers on transient ischemia-induced retinal ganglion cell death [PDF]

open access: yes
Objective: To evaluate the suppressive effect of two free radical scavengers, edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one) and Trolox® (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid), on retinal ganglion cell death in transgenic Thy1-EGFP ...

Tumor‐Targeted Hyaluronic Acid/Tannic Acid‐Engineered Oxygen Nanogenerators With IR780 Payloads Enable Dual‐Mode Glutathione Depletion and Effective Singlet Oxygen Generation for Melanoma Treatment

open access: yesAdvanced Healthcare Materials, EarlyView.
A hyaluronic acid/tannic acid‐engineered Prussian blue oxygen nanogenerator loaded with IR780 is developed to enhance melanoma phototherapy. By integrating tumor targeting, oxygen self‐supply, and dual‐mode glutathione depletion, the nanoplatform effectively overcomes hypoxia and antioxidant defenses, potentiating synergistic photothermal/photodynamic ...

Synthesis and Antioxidant Activity of Novel Biginelli Adducts with Phenolic Fragments

open access: yesApplied Sciences
In this work, eco-friendly ceric ammonium nitrate (CAN) and ferric chloride hexahydrate catalysts in ethanol/acetonitrile systems were used to efficiently synthesize novel dihydropyrimidinone (-thione) derivatives via the Biginelli reaction. The obtained

Synthetic analogs of phytoalexins. Synthesis and antifungal activity of potential free-radical scavengers

open access: yes, 1989
The mechanism of fungicidal action of phytoalexins has not yet been clearly established. Some authors have suggested that they can give rise to radicals upon irradiation with UV light; therefore, we have synthesized some stilbenes, chalcones, and ...

PLL‐g‐HPA Hydrogel Microneedles Loaded With Rhoifolin Target Macrophages to Alleviate Fibroblast Senescence for Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Diabetic wound healing is hindered by a pathological crosstalk wherein elevated IL‐11 induces M1 macrophage polarization, leading to IL‐1β/IL‐6 release and subsequent fibroblast senescence via RAS/p38MAPK/p53/E2F1 signaling. Here, we develop a Gel@M‐Rho microneedle patch that delivers rhoifolin‐loaded, macrophage membrane‐coated nanoparticles to target
