Engineering a Nanostructured Hybrid Gel System with Sodium Humate for Enhanced Wound Healing.
Article in Journal of functional biomaterials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 development of effective topical drug delivery systems remains a key challenge in wound management, particularly for bioactive compounds with limited skin permeability. In this study, a nanostructured bigel system incorporating sodium humate-loaded ultra-deformable vesicles (UDVs) was developed and evaluated for wound healing applications. Sodium humate-loaded UDVs were prepared using a thin-layer hydration method, and the influence of key technological parameters (phospholipid/glycerol concentrations, sonication time) on vesicle size and encapsulation efficiency was investigated. An optimized UDV formulation characterized by small particle size, high stability, and high drug encapsulation efficiency was selected and incorporated into a bigel composed of hydroxypropyl methylcellulose hydrogel and andiroba oil oleogel. The developed bigels were characterized in terms of microstructure, physical stability, pH, spreadability, and rheological behavior, demonstrating suitable properties for dermal application. In vivo wound healing evaluation in rat wound models revealed that bigels containing sodium humate-loaded UDVs significantly enhanced wound closure and tissue regeneration compared to control and reference treatments. Histopathological analysis confirmed improved granulation tissue formation and complete epithelialization. Overall, the results demonstrate that the proposed UDV-loaded hybrid bigel represents a promising nanostructured platform for enhanced dermal delivery and wound healing therapy.
