Vegetable Butter-Based Nanocarriers: Do Nanoparticulation and Quercetin Loading Modulate In vitro Cellular Effects Involved in Wound Healing?
Article in AAPS PharmSciTech, 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 need for advanced yet cost-effective topical strategies for chronic skin wounds motivated this study to evaluate nanostructured lipid carriers (NLCs) based on shea or cocoa butter. Our first goal was to compare NLCs with conventional emulsions to evaluate whether butter nanoparticulation confers biological advantages for wound-related applications. NLCs were produced by hot homogenization-sonication and characterized in terms of particle size, polydispersity, morphology, and stability. Both butter-based NLCs formed stable, monodisperse nanometric systems (size 197-240 nm, PDI < 0.2). In HaCaT keratinocytes, shea and cocoa butter-based NLCs significantly enhanced proliferation (up to 137% for shea and 127% for cocoa butter) and wound repopulation (up to 96% and 65%, respectively) compared with the respective emulsions. Our second goal was to assess the effect of quercetin (QT) incorporation in the NLCs, since oxidative stress has been related to healing difficulties. QT incorporation did not further increase proliferation or repopulation but significantly improved antioxidant protection, reducing H₂O₂-induced intracellular reactive oxygen species by up to 53-62% at 12 µg/mL QT. Shea butter-based NLCs exhibited superior biological performance, including a modest intrinsic antioxidant effect (~ 15% DPPH inhibition), probably due to endogenous lipid bioactives. QT-loaded shea butter NLCs promoted enhanced QT retention within the stratum corneum (~ 14 vs. ~ 9 µg/cm
