"Attractive" Treatment for Abdominal Aortic Aneurysm Repair: Magnetic Localization of Silk-Iron Packaged Extracellular Vesicles.
Article in Journal of functional biomaterials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Abdominal aortic aneurysm (AAA) is a dilatation of the distal aorta to a diameter of 50% or more of its normal size of about 2 cm. Risk of aortic rupture can be nearly eliminated with either open surgery or endovascular repair. Procedural risks limit the value of these interventions unless the diameter of the aneurysm has reached a critical threshold (established as 5.5 cm in men or 5.0 cm in women). Thus, patients are monitored until this threshold is reached. Approximately 80% of small AAA will grow and exceed the threshold, providing a therapeutic window for altering this natural history and reducing the risk of rupture. Previous work in our lab has utilized adipose-derived mesenchymal stem cells (ASCs) to treat AAA in vivo, preserving elastic fibers and slowing aneurysm expansion. This work sought to create a delivery system for therapeutic extracellular vesicles (ASC-EVs) secreted by ASCs. Our delivery system incorporated the biocompatibility of regenerated silk fibroin (RSF), the magnetic moveability of iron oxide nanoparticles (IONPs), and the regenerative nature of ASC-EVs to create silk-iron packaged extracellular vesicles (SIPEs). Using this system, we tested the ability to magnetically localize the SIPEs and release their encapsulated ASC-EVs to exert their regenerative effects in vitro. We were successful in magnetically localizing the SIPEs in vitro and silk-iron microparticles (SIMPs) in vivo and in detecting their releasates via flow cytometry and cellular uptake assays. However, while their releasates were detected, their biological effects were diminished compared to unencapsulated controls. Thus, additional optimization related to loading efficiency is needed.
