Chitosan-Based Intelligent Microneedles for Delivery of Amphotericin B Loaded Oleosomes: Antifungal Ocular Patch Targeting for Effective Against Fungal Keratitis Using Rabbit Model via TLR4/NLRP3 Pathway.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Fungal keratitis (FK), a major cause of blindness, remains challenging to treat due to poor drug penetration and antifungal resistance. Amphotericin-B (AmB), a water-insoluble and low-permeability, necessitates innovative delivery systems to improve its therapeutic efficacy. Methods: AmB was encapsulated within oleosomes (Ole) prepared using the ethanol injection method, using phosphatidylcholine (Lipoid S100) and sodium oleate, resulting in nanosized spherical globules. The optimized Ole were characterized, then the selected Ole were incorporated into sodium polyacrylate/PEG/chitosan-based microneedles (AmB-Ole/MNs) to improve ocular delivery by creating transient microchannels on the eye surface. Results: The optimized Ole showed a droplet size of (175 ± 0.78 nm), polydispersity index of (0.33 ± 0.04), zeta potential of (31 ± 0.43 mV), high entrapment efficiency (91±0.63%), and improved stability, bioavailability, and controlled drug release. The AmB-Ole/MNs system increases corneal penetration and contact time via transient microchannels in the eye surface, achieving sustained drug delivery over 72 hours with 70% ex vivo permeation over 80 hours compared to AmB. In vitro antifungal activity and histopathological examination showed that the AmB-Ole/MNs system has potent biofilm disruption (>90%) and 27 mm and 32 mm zones of inhibition against Conclusion: The AmB-Ole/MNs system as an innovative ocular delivery platform for fungal keratitis offers sustained drug release, enhanced permeation, potent antifungal activity, and reduced toxicity. AmB-Ole/MNs showed promise for ocular AmB delivery for FK.
