AI Article Synopsis
- Interest is growing in using essential oils for topical drug delivery, particularly in wound healing, through nanostructured lipid carriers (NLC).
- The study developed NLC that successfully combined ferulic acid and essential oils, yielding nanoparticles that are stable, small, and highly efficient in encapsulation.
- Results showed that this combination not only improves cell compatibility and migration in fibroblasts but also enhances the overall effectiveness compared to traditional drug solutions, suggesting a promising approach for wound treatment.
Article Abstract
Nowadays, an increasing interest in combinatorial drug delivery systems is emerging, highlighting the possibility of exploiting essential oils (EO) for topical applications. This work aimed at developing nanostructured lipid carriers (NLC) for the combined delivery of ferulic acid and EO, whose beneficial effects in wound-healing processes have been widely reported. Homogeneous (polydispersity index, PDI < 0.2) nanoparticles with a small size (<150 nm) and a high encapsulation efficiency (>85%) were obtained. The co-presence of ferulic acid and EO, as compared to synthetic isopropyl myristate-based NLC, increased nanoparticles' stability, due to higher ordering chains, as confirmed by morphological and physicochemical studies. An enhanced cytocompatibility was observed when combining ferulic acid and EO, as confirmed by in vitro studies on fibroblasts. Furthermore, the combined delivery of ferulic acid and EO significantly promoted cell migration with higher effectiveness in respect to the free drug solution and the carrier without the EO. Taken all together, our results suggest a potential combined effect of the antioxidant ferulic acid and EO co-delivered in lipid nanoparticles in promoting cell proliferation and migration, representing a promising strategy in the treatment of wounds.

Acetyl xylan esterase plays a crucial role in the degradation of xylan, the major plant hemicellulose, by liberating acetic acid from the backbone polysaccharides. Acetyl xylan esterase B from Aspergillus oryzae, designated AoAxeB, was biochemically and structurally investigated. The AoAxeB-encoding gene with a native signal peptide was successfully expressed in Pichia pastoris as an active extracellular protein.

Lignin, the most abundant renewable source of aromatic compounds on earth, remains underexploited in traditional biorefining. Fraxetin, a naturally occurring flavonoid, has garnered considerable attention in the scientific community due to its diverse and potent biological activities such as antimicrobial, anticancer, antioxidant, anti-inflammatory, and neurological protective actions. To enhance the green and value-added utilization of lignin, Saccharomyces cerevisiae was engineered as a cell factory to transform lignin derivatives to produce fraxetin.

The combination of polyphenols and protein can improve the functional characteristics of protein. How to effectively promote the binding of polyphenols to protein is still a difficult topic. In this study, hydrodynamic cavitation (HC) was used to induce the fabrication of complexes between soy protein isolate (SPI) and different polyphenols (tannic acid (TA), chlorogenic acid (CGA), ferulic acid (FA), caffeic acid (CA), and gallic acid (GA)).

Introduction: Fungal endophytes have mutualistic associations with the plant's host, communicating through genetic and metabolic processes. As a result, they gain the ability to generate therapeutically effective metabolites and their derivatives.
Methods: The current study aims to assess antioxidant potential along with the identification of robust metabolites within the crude extract of a potent endophytic fungus Xylaria ellisii isolated from leaf tissues of the Acorus calamus Linn plant.

Pathogen invasion and persistent inflammatory storms caused by bacterial infections are the main challenges to the healing of infected wounds. Herein, this study proposed a pH-responsive polysaccharide hydrogel dressing (CG-HA) composed of cationic guar gum (CG) and hyaluronic acid (HA). Additionally, Zn and ferulic acid (FA)/β-cyclodextrin (β-CD) inclusion complexes (FA/β-CD) were co-introduced into the CG-HA hydrogel to form the desired FA/β-CD@CG-HA-Zn hydrogel.
