Abstract
Chronic exposure to ultraviolet (UV) radiation leads to photoaging. There is a tremendous rise in products having a dual activity of photoprotection and antiaging. In vitro analysis in dermal fibroblasts and their biological mechanisms involved are critical to determine antiaging potential. The study aimed to investigate the antiaging potential of sunscreen formulated from nanostructured lipid carrier and tocotrienol-rich fraction (NLC-TRF sunscreen). The antioxidant activity of the NLC-TRF sunscreen was evaluated by radical scavenging and hydrogen peroxide inhibition properties. Also, collagenase, elastase and matrix metalloproteinase-1 (MMP-1) inhibition activities, and type I collagen and elastin protein expression were studied. Quantitative real-time polymerase chain reaction (qPCR) was used to evaluate the mRNA expression of fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), transforming growth factor-β1 (TGF-β1), type I collagen (COL1A1), elastin (ELN), MMP-1, MMP-2, and tissue inhibitor matrix metalloproteinase-1 (TIMP-1). The results suggested that NLC-TRF sunscreen is effective in radical, anti-hydrogen peroxide, and collagenase, elastase and MMP-1 inhibition activities. Besides, a significant increase for type I collagen (3.47-fold) and elastin (2.16-fold) protein and fibroblast regeneration genes (FGF (2.12-fold), VEGF (1.91-fold), TGF-β1 (2.84-fold), TIMP-1 (1.42-fold), ELN (2.13-fold)) were observed after sample treatment. These findings support the therapeutic potential of NLC-TRF sunscreen in antiaging.

Int J Mol Sci 2020; 21:ijms21082909. [PMID: 32326342 PMCID: PMC7216267 DOI: 10.3390/ijms21082909] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 04/17/2020] [Accepted: 04/20/2020] [Indexed: 02/06/2023] Open
Abstract
There is increasing concern for reduction of the ecological impacts of industrial waste caused by fruits and vegetables. To reduce costs of onion waste disposal while obtaining value-added products, onion skin can be used to extract quercetin, a natural flavonoid with antioxidant, anti-inflammatory and anti-cancer effects. The aim was to optimize quercetin extraction from brown onion (Allium cepa L.) skin through investigation of the effects of different parameters on quercetin yield. Operational parameters for conventional maceration extraction and for ultrasound-assisted extraction were compared: solvent type, mass-to-liquid ratio, extraction time and temperature. Antioxidant capacity was determined using DPPH· radical scavenging assays and quercetin yield using HPLC/DAD. Anti-α-amylase activity of onion skin extracts was investigated using α-amylase inhibition assays. Optimal extraction conditions of quercetin from onion skin were obtained with maceration extraction, 50% ethanol, 1:100 mass-to-liquid ratio, 25 °C, for 15 min. Under these conditions, the antioxidant capacity (expressed as quercetin equivalents) was 18.7 mg/g and the mass fraction of quercetin was 7.96 mg/g. The onion skin extracts showed a dose-dependent relationship between dry extract concentration and α-amylase inhibition, which confirms that this onion skin extract can be considered as an anti-diabetes agent.

Flavonoid composition, cellular antioxidant activity and (myelo)peroxidase inhibition of a Bryonia alba L. (Cucurbitaceae) leaves extract. J Pharm Pharmacol 2018; 71:230-239.

Abstract
OBJECTIVES The aim of the present study consisted in the isolation of flavonoids from the leaves of Bryonia alba L. and evaluation of their antioxidant activity and inhibition on peroxidase-catalysed reactions. METHODS Flavonoids were isolated by preparative HPLC-DAD and their structures were elucidated by MS and NMR. Inhibitory effect was tested by the horseradish peroxidase and the myeloperoxidase assays. Cellular antioxidant assays consisted in testing the inhibitory activity on the reactive oxygen species released upon activation of neutrophils freshly isolated ex vivo from equine blood and of human monocytes-derived macrophages in vitro. Whole organism toxicity was assessed on zebrafish larvae. KEY FINDINGS Four flavonoids (lutonarin, saponarin, isoorientin and isovitexin) were isolated. The performed assays showed significant antioxidant activity and inhibition for the peroxidase-catalysed reactions. Absence of cellular and zebrafish toxicity was confirmed. CONCLUSIONS Bryonia alba L. leaves are particularly interesting for their flavonoids content and showed significant inhibitory effect on peroxidase-catalysed oxidation of substrates (Amplex Red and L012), as well as antioxidant/antiradical activity, proving that this species has a medicinal potential. Moreover, the present study highlights the absence of the toxicity of these leaves and offers though a novel perspective on the species, previously known as being toxic.

Smartphone-based enzymatic biosensor for oral fluid L-lactate detection in one minute using confined multilayer paper reflectometry. Biosens Bioelectron 2017; 94:124-130.

Abstract
The development of smartphone-based biosensors for point-of-care testing (POCT) applications allows realizing "all in one" instruments, with large potential distribution among the general population. With this respect, paper color-based detection performed by reflectance measurement is the most popular, simple, inexpensive and straightforward method. Despite the large number of scientific publications related to these biosensors, they still suffer from a poor detectability and reproducibility related to inhomogeneity of color development, which leads to low assay reproducibility. To overcome these problems, we propose a smartphone paper-based biosensor, in which all the reagents necessary to complete the analysis are co-entrapped on paper in a "wafer"-like bilayer film of polyelectrolytes (Poly (allyl amine hydrochloride/poly(sodium 4-styrene sulfonate)). Using a 3D printing low-cost technology we fabricated the smartphone-based device that consists in a cover accessory attached to the smartphone and incorporating a light diffuser over the flash to improve the image quality, a mini dark box and a disposable analytical cartridge containing all the reagents necessary for the complete analysis. The biosensor was developed exploiting coupled enzyme reactions for quantifying L-lactate in oral fluid, which is considered a biomarker of poor tissue perfusion, a key element in the management of severe sepsis, septic shock and in sports performance evaluation. The developed method is sensitive, rapid, and it allows detecting L-lactate in oral fluid in the relevant physiological range, with a limit of detection of 0.1mmolL-1. The extreme simplicity of assay execution (no reagents need to be added) and flexibility of fabrication of the device, together with the high assay versatility (any oxidase can be coupled with HRP-based color change reaction) make our approach suitable for the realization of smartphone-based biosensors able to non-invasively detect a large variety of analytes of clinical interest.
