A Nose-to-Brain Delivery System for Taxifolin Ameliorates Alzheimer's Disease via Synergistic Attenuation of Oxidative Stress and Mitochondrial Dysfunction.
Article in Antioxidants (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The blood-brain barrier (BBB) presents the principal obstacle to drug delivery for Alzheimer's disease (AD), severely restricting brain bioavailability and therapeutic efficacy. Taxifolin (TF) is a potent natural antioxidant with significant therapeutic potential. To enhance its efficacy in treating AD, we developed a brain-targeted delivery system based on a taxifolin-loaded thermosensitive hydrogel (TF-Gel). This platform integrates TF with a poly(N-isopropylacrylamide)-based thermosensitive hydrogel to enhance brain delivery, tissue penetration, and intracerebral retention via intranasal administration. TF-Gel exhibits excellent structural stability and functional performance, enabling efficient bypass of the BBB through the nasal-brain pathway. Furthermore, it regulates mitochondrial dysfunction, reverses abnormal levels of adenosine triphosphate (ATP), reactive oxygen species (ROS), and malondialdehyde (MDA) in neuronal mitochondria, repairs mitochondrial energy metabolism, restores mitochondrial dynamic balance, improves oxidative stress damage, and blocks cell apoptosis pathways. Collectively, these results highlight the strong potential of the TF-Gel nasal delivery system as a mitochondria-targeted therapeutic strategy for AD.
