Abstract
Cypermethrin is a synthetic pyrethroid reported to cause hepatic toxicity and other fatalities in humans as well as animals/birds. Quercetin is a flavonoid that has beneficial health-protective effects, its use is limited because of its poor bioavailability, metabolism through colonic microbial flora, and first-pass hepatic metabolism. To overcome these limitations, quercetin was loaded into chitosan nanoparticles by following the solvent evaporation method. The study objectives were synthesizing, characterizing quercetin-loaded chitosan nanoparticles, and determination of hepatoprotective potential against chemical (pyrethroid) induced liver injury in animal models. The nanoparticles were characterized by zeta size and potential, polydispersity index (PDI), entrapment efficiency, and FTIR. The prepared nano-formulation was physically stable and fell within the nanoscale range (188.5 nm) with high entrapment efficiency (80.4%). The study was conducted with four treatment groups (n = 5) comprising 20 rabbits, in which group 1 was the negative control (normal diet), group 2 was a positive control (cypermethrin 24 mg/Kg), group 3 and 4 were treated with low-dose (10 mg/kg) and high-dose (20 mg/kg) quercetin-loaded chitosan nanoparticles respectively, along with cypermethrin 24 mg/kg) for 28 days. It was found that cypermethrin-treated animals have high levels of LFT and histopathological lesions in the liver. Co-administration of quercetin-loaded chitosan nanoparticles with cypermethrin successfully ameliorated hepatotoxicity in rabbits in a dose-dependent manner.

Abstract
The domain of nanoscience has observed significant advancements over the former two decades. Researchers in nanomedicine field have been rigorously exploring the employment of natural biodegradable polymers for targeted drug delivery (TDD). Chitosan (CS), acquired from the deacetylation of chitin, is a naturally occurring amino polysaccharide, whose features of non-toxicity, prolonged retention time, biocompatibility, increased bioavailability, and biodegradability have hastened extensive study into diverse applications. The presence of amino and hydroxyl groups within CS is crucial for its noteworthy characteristics, comprising mucoadhesion, improvement of permeation, drug's-controlled release,in situgel preparation, and antimicrobial activity. CS nanoparticles (CS NPs) portray a safe and competent class of nanocarrier systems, demonstrating the controlled release of drugs and preciseness in TDD, and are found hopeful for treating wounds. However, safety concerns such as potential toxicity, immune response, and hemocompatibility must be carefully evaluated to ensure their suitability for clinical applications. This article explores the potential of CS NPs as versatile carriers for TDD, reporting essential challenges in both therapeutic domains, and progressing the advancement of innovative treatments. By connecting drug delivery and wound healing, our review addresses a critical convergence, fostering developments that can certainly affect treatment and recovery of patient. The initial part of the review will shed light on the extraction sources and notable attributes of CS. Additionally, we have presented recent research findings on how CS NPs are being utilized for drug delivery via different routes of administration. Further, we have endeavored to represent the latest investigations on the applications of CS NPs in wound healing.

Abstract
Quercetin is abundant in plants and has notable pharmacological properties for skin health. This review aims to comprehensively evaluate the effects of quercetin on skin-related issues, adhering to the PRISMA guidelines and analyzing studies from ScienceDirect, Web of Science, Scopus, and PubMed. Of the 1,398 studies identified, 65 studies met the criteria for meta-analysis. The meta-analysis indicated that quercetin had powerful antioxidant properties, protecting against oxidative stress by significantly lowering levels of MDA (Z-score, 2.51), ROS (Z-score, 3.81), and LPO (Z-score, 4.46), and enhancing enzymes of GSH (Z-score, 5.46), CAT (Z-score, 5.20), and SOD (Z-score, 4.37). Quercetin acted as an anti-inflammatory by significantly suppressing protein regulators such as NF-κβ, AP-1, and MAPKs (ERK and JNK), cytokines of TNFα, IL-6, IL-1β, IL-8, and MCP-1, and enzymes of COX-2, iNOS, and MPO, while upregulating the cytokine IL-10. Additionally, quercetin significantly suppressed IL-4 (Z-score, 3.16) and IFNγ (Z-score, 3.76) cytokines involved in chronic inflammation of atopic dermatitis. Quercetin also supported wound healing by significantly decreasing inflammatory cells (Z-score, 5.60) and enhancing fibroblast distribution (Z-score, 5.98), epithelialization (Z-score, 8.57), collagen production (Z-score, 4.20), and angiogenesis factors of MVD (Z-score, 5.66) and VEGF (Z-score, 3.86). Furthermore, quercetin significantly inhibited tyrosinase activity (Z-score, 1.95), resulting in a significantly reduced melanin content (Z-score, 2.56). A significant reduction in DNA damage (Z-score, 3.27), melanoma cell viability (Z-score, 2.97), and tumor formation was also observed to ensure the promising activity of quercetin for skin issues. This review highlights quercetin's potential as a multifaceted agent in skin care and treatment.

Abstract
The development of advanced wound dressings with enhanced absorption capacity and reduced adhesion is critical for effective wound management. This study presents a novel approach utilizing nickel (Ni) nanoparticles synthesized using curcumin extracted from Curcuma longa, known for its wound healing and antimicrobial properties. The Ni nanoparticles were incorporated with chitosan and polyethylene glycol (PEG) to form cross-linked nanocomposites with improved absorptive and mechanical properties. The wound healing potential was assessed through histopathological analysis, wound contraction rates, and antibacterial activity against Escherichia coli. The results demonstrated accelerated wound closure within 10-12 days, enhanced tissue regeneration, and significant antibacterial efficacy. Structural and compositional analyses, including UV-Visible spectroscopy, FTIR, XRD, Zeta Potential, EDX, and SEM, confirmed the successful synthesis and stability of the nanocomposites. This study highlights the potential of curcumin-loaded nanocomposites (CS-Ni and PEGNi) as a promising wound dressing material, paving the way for nanotechnology-driven innovations in wound care and tissue engineering.

Abstract
Although the skin has a high healing capacity, severe skin wounds often require external interventions to heal properly. Tissue-engineered wound dressings have indeed gained significant attention among various treatment strategies for wound healing. This study focuses on the integration of polyvinyl pyrrolidone (PVP), quaternized chitosan (QCS), and dextran (DEX) to prepare a ternary composite (PVP/QCS/DEX) as a wound dressing hydrogels with varying concentration of PVP and DEX. A variety of analytical methods, including infrared spectroscopy (FTIR), scanning electron microscopy (SEM), contact angle, and water vapor transmission rate (WVTR) were employed to assess the characteristics of the samples. The uniform and interconnected porous structure of the samples was confirmed by the SEM results. All the samples showed high porosity and water vapor transition rate, demonstrating their ability to provide a suitable moist environment and efficient exudate handling for wound healing. The antibacterial test conducted on hydrogels demonstrated the antibacterial activity of hydrogels and drug-loaded hydrogel samples including Escherichia coli and Staphylococcus aureus. The in vitro cytotoxicity evaluation using the MTT assay demonstrated that the developed PVP/QCS/DEX hydrogels exhibit satisfactory cytocompatibility and promote cell viability. The results of the scratch assay indicated that the samples had promoted the cell migration and would improve and accelerate wound healing process. The in vivo healing tests conducted by the drug-loaded hydrogel sample revealed a promising healing performance. Therefore, based on the favorable performance observed throughout the various tests and analysis, the as-prepared PVP/QCS/DEX hydrogels show significant promise in the field of wound dressings.

Abstract
Food packaging industries are growing to meet consumer demand and prevent pollution by adopting significant biopolymer advancements. Therefore, this study aimed to develop functionally active chitosan (CS)/polyvinyl alcohol (PVA)-based biopolymer films and evaluate the effect of Justicia Adhatoda extract (JAE), pure quercetin (Q), and CS-capped quercetin nanoparticles ((Q)CS NPs) on sustainable bread packaging. CS was successfully loaded onto (Q) by the one-pot method, which was confirmed by light absorption spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The fabricated films were examined using different analytical techniques. FTIR and XRD patterns confirmed that the CS/PVA matrix had molecular interactions through hydrogen bonds with JAE, (Q), and (Q)CS NPs. SEM micrograms revealed a uniform distribution and denser surface with small aggregations by adding (Q)CS NPs. The (Q)CS NPs added CPE(Q)CS nanocomposite exhibited excellent UV light shielding (99.99 % UV-A and UV-B blocking), water resistance ability (contact angle:99.44°, WVP:3.68×10-7 gh-1m-1Pa-1), and oxygen (0.614×10-6gh-1 m-1 atm-1) barrier properties. Adding (Q)CS NPs enhanced the antimicrobial properties of CPE(Q)CS against foodborne microbes (E. coli:15.45 mm, P. aeruginosa:14.50 mm, B. subtilis:14.25 mm, S. aureus:13.52 mm, and C. albicans:15.16 mm). In addition, incorporating (Q)CS NPs, increased the shelf life of bread compared to unpacked and polyethylene-packed bread samples.

Abstract
PURPOSE Photoaging is characterised by cutaneous changes caused by exposure to ultraviolet light over time. Quercetin is a bioflavanoid with antioxidant, antineoplastic, and anti-inflammatory effects. This study investigated the therapeutic effects of topical quercetin on photoaging, a phenomenon not previously studied in ultraviolet A (UVA)-induced photoaging. METHODS A total of 40 rats were randomly categorised into 5 groups, each comprising 8 rats. A photoaging model was induced by applying UVA to the dorsal region of all rats, except for the negative control group. Topical 0.1% retinoic acid was applied to one UVA group, topical 0.3% quercetin to another UVA group, and both agents were applied in combination to yet another UVA group 5 days a week for 8 weeks. Subsequently, wrinkle values were measured, reactive oxygen species (ROS) and matrix metalloproteinase-1 (MMP-1) levels were analysed, and histopathological parameters were examined. RESULTS The wrinkle value of the UVA group was found to be significantly higher than that of the UVA + Quercetin group. Collagen damage was lower in the UVA + Quercetin group than in the UVA group, although this difference was not statistically significant. Compared with the UVA + Retinoic Acid group, the UVA + Quercetin group exhibited a more significant decrease in inflammation. MMP-1 values were considerably higher in the UVA + Retinoic Acid and UVA + Quercetin + Retinoic Acid groups as well as in the UVA + Quercetin group compared with the control and UVA groups. CONCLUSION The present study showed that quercetin can be utilised in the treatment of photoaging, especially when combined with retinoic acid.

Abstract
Wound healing is a multifaceted, complex process that factors like aging, metabolic diseases, and infections may influence. The potentiality of polyphenols, natural compounds, has shown anti-inflammatory and antimicrobial properties in promoting wound healing and their potential applications in wound management. The studies reviewed indicate that polyphenols have multiple mechanisms that promote wound healing. This involves enhancing antioxidant defenses, reducing oxidative stress, modulating inflammatory responses, improving healing times, reducing infection rates, and enhancing tissue regeneration in clinical trials and in vivo and in vitro studies. Polyphenols have been proven to be effective in managing hard-to-heal wounds, especially in diabetic and elderly populations. Polyphenols have shown significant benefits in promoting angiogenesis and stimulating collagen synthesis. Polyphenol treatment has been demonstrated to have therapeutic effects in wound healing and chronic wound management. Their ability to regulate key healing processes makes them suitable for new wound care products and treatments. Future research should enhance formulations and delivery methods to optimize polyphenols' bioavailability and therapeutic efficacy in wound management approaches.

Abstract
Skin aging represents a multifactorial process influenced by both intrinsic and extrinsic factors, collectively known as the skin exposome. Cellular senescence, characterized by stable cell cycle arrest and secretion of pro-inflammatory molecules, has been implicated as a key driver of physiological and pathological skin aging. Increasing evidence points towards the role of senescence in a variety of dermatological diseases, where the accumulation of senescent cells in the epidermis and dermis exacerbates disease progression. Emerging therapeutic strategies such as senolytics and senomorphics offer promising avenues to target senescent cells and mitigate their deleterious effects, providing potential treatments for both skin aging and senescence-associated skin diseases. This review explores the molecular mechanisms of cellular senescence and its role in promoting age-related skin changes and pathologies, while compiling the observed effects of senotherapeutics in the skin and discussing the translational relevance.

Abstract
AbstractIn 2023, breast cancer is expected to have nearly 2 million new cases, making it the second most common cancer overall and the most prevalent among women. Multidrug resistance limits the effectiveness of chemotherapy; however, quercetin, a natural flavonoid, helps combat this issue. The goal of the current investigation is to determine the impact of a novel composite of quercetin and selenium nanoparticles (SeNPs) on the breast cancer cell lines MDA-MB-231 and MCF-7 in order to enhance quercetin’s tumor-suppressive action and decrease selenium (Se) toxicity. Particle size, zeta potential, FTIR, SEM, UV–VIS spectroscopy, and EDX were used to characterize quercetin-selenium nanoparticles (Que-SeNPs), in addition to evaluation of the antioxidant, apoptotic, and anticancer properties. Moreover, autophagy (Atg-13) protein receptors and PD-1/PD-L1 checkpoint were targeted using molecular docking modeling and molecular dynamics (MD) simulations to assess the interaction stability between Que-SeNPs and three targets: PDL-1, PD-1, and Atg-13HORMA domain. Que-SeNPs, synthesized with quercetin, were stable, semi-spherical (80–117 nm), and had a zeta potential of − 37.8 mV. They enhanced cytotoxicity, antioxidant activity, and apoptosis compared to quercetin alone in MCF-7 and MDA-MB-231 cells. Docking simulations showed strong binding to the PD-1/PD-L1 checkpoint and Atg-13HORMA protein receptors. Moreover, the molecular dynamics simulation revealed that the behavior of the PD-L1 intriguing insights into its structural dynamics, therefore, suggesting a stable phase where the complex is adjusting to the simulation environment. The present data confirmed that the stable formula of Que-SeNPs is cytotoxic, antioxidant, and has a potential activity to increase apoptosis in breast cancer cells, with the potential to inhibit PD-1/PD-L1 and Atg-13 proteins.

Abstract
BACKGROUND The skin represents the first barrier of defense, and its integrity is crucial for overall health. Skin wounds present a considerable risk seeing how their progression is rapid and sometimes they are caused by comorbidities like diabetes and venous diseases. Nutraceutical combinations like the ones between polyphenols and metal ions present considerable applications thanks to their increased bioavailability and their ability to modulate intrinsic molecular pathways. METHODS The research findings presented in this paper are based on a systematic review of the current literature with an emphasis on nanotechnology and regenerative medicine strategies that incorporate polyphenols and metallic nanoparticles (NPs). The key studies which described the action mechanisms, efficacy, and safety of these hybrid formulations were reviewed. RESULTS Nanocomposites of polyphenol and metal promote healing by activating signaling pathways such as PI3K/Akt and ERK1/2, which in turn improve fibroblast migration and proliferation. Nanoparticles of silver and copper have antibacterial, angiogenesis-promoting, inflammation-modulating capabilities. With their ability to induce apoptosis and restrict cell growth, these composites have the potential to cure skin malignancies in addition to facilitating wound healing. CONCLUSIONS Nanocomposites of polyphenols and metals provide hope for the treatment of cancer and chronic wounds. Their antimicrobial capabilities, capacity to modulate inflammatory responses, and enhancement of fibroblast activity all point to their medicinal potential. Furthermore, these composites have the ability to decrease inflammation associated with tumors while simultaneously inducing cell death in cancer cells. Clarifying their mechanisms, guaranteeing stability, and enhancing effective delivery techniques for clinical usage should be the focus of future studies.

Abstract
Skin wounds can drive global impacts, socially and economically, in parallel with their elevated incidence rate. Therefore, utilizing the dual-activity of Brassica Oleracea (Red Cabbage) extract, of being pH-sensitive and biologically active in designing novel, therapeutic, and pH-sensitive wound dressings with an easily stripped-off feature, is critical. Wound dressings were designed using two separate hydrogels based on chitosan (CS) and hydroxyethylcellulose (HEC), each loaded with RCE. The pH sensitivity of prepared bandages exhibited a noticeable visual change in color during wound treatment. Wound closure has reached 99.69 % for CS/RCE dressings. Results showed that RCE had raised the hydroxyproline and collagen content in the healed skin. Histopathological investigation proves that skin returned to its regular thickness within 10 days of treatment. RCE showed marked improvement in the healing quality by acting as an antioxidant, anti-inflammatory, and antimicrobial agent. Therefore, dual-function dressings are potential candidates to sense and cure skin wounds.

Abstract
OBJECTIVE Genotoxicity assays include micronucleus test, comet assay, and malformed sperm head used to investigate the protective potential of quercetin (Que) and Que nanoparticles against imidacloprid (IMI)-induced genotoxicity in Swiss albino mice. METHODS The ionic gelation procedure was used to synthesize the Que nanoparticles and characterized for their hydrodynamic diameter, zeta potential, scanning electron microscopy (SEM), transmission electron microscopy (TEM), FT-IR, and encapsulation efficiency. A total of 48 mice were taken in eight groups with six animals in each group. Groups 1, 2, 3, and 4 received 3% gum acacia, 22 mg/kg IMI, 25 mg/kg Que and 25 mg/kg Que nanoparticles high dose (QNPs (HD)), respectively. Groups 5, 6, 7, and 8 received 22 mg/kg IMI + 25 mg/kg Que (IMI + Que), 22 mg/kg IMI + 25 mg/kg Que nanoparticles (IMI + QNPs (HD)), 22 mg/kg IMI + 12.5 mg/kg Que nanoparticle medium dose (IMI + QNPs (MD)), and 22 mg/kg IMI + 6.25 mg/kg Que nanoparticles low dose (IMI + QNPs (LD)), respectively. RESULTS The IMI causes genotoxicity in bone marrow cells by increasing the frequency of micronuclei and the comet tail length. Additionally, IMI is mutagenic to germ cells, as determined by a test for aberrant sperm heads. Both Que and Que nanoparticles lessen the genotoxicity that IMI induces when administered together or separately. Histopathological findings also revealed degenerative changes in bone marrow and testes in IMI administered group as compared to control. CONCLUSION Quercetin and Que nanoparticles showed marked ameliorative effect by restoring the degenerative changes produced by IMI.

Abstract
Diabetic ulcers present a formidable obstacle in diabetes management, typically leading to high mortality and amputation rates. To overcome traditional monotherapy drawbacks, We developed a novel microneedle strategy for combined antimicrobial action: ingeniously integrating quercetin with Platelet-derived Growth Factor-BB(PDGF-BB) and Sucrose Octasulfate(SOS) into the microneedle system(QPS MN). This method allows to penetrate through biofilms, administering quercetin nanocrystals and PDGF-BB deep into the tissue to combat microbial infection, mitigate inflammation, and promote angiogenesis. The accompanying backing material contains SOS, which absorbs wound exudate and forms a dressing that provides a moist environment for wound healing In an in vitro wound-scratch assay demonstrated that co-cultivating Human Umbilical Vein Endothelial Cells(HUVEC) with QPS MN for 48 h (90.3 ± 2.51 %) significantly enhanced cell migration compared to the control group (20.2 ± 1.41 %). Moreover, treatment of streptozotocin-induced diabetic wounds in rats with QPS MN for 14 days resulted in a wound healing rate of 96.56 ± 3.44 %, far surpassing the healing rate of only 40.34 ± 7.26 % observed in the untreated control group. Furthermore, the QPS MN treated wounds exhibited a notable increase in skin appendages and neovascularisation, indicating promising potential for achieving complete wound healing. These results suggest that QPS MN may offer substantial therapeutic benefits for addressing diabetic wounds.

Abstract
Wound healing involves a carefully regulated sequence of events, encompassing pro-inflammatory and anti-inflammatory stages, tissue regeneration, and remodeling. However, in individuals with diabetes, this process gets disrupted due to dysregulation caused by elevated glucose levels and pro-inflammatory cytokines in the bloodstream. Consequently, the pro-inflammatory stage is prolonged, while the anti-inflammatory phase is delayed, leading to impaired tissue regeneration and remodeling with extended healing time. Furthermore, the increased glucose levels in open wounds create an environment conducive to microbial growth and tissue sepsis, which can escalate to the point of limb amputation. Managing diabetic wounds requires meticulous care and monitoring due to the lack of widely available preventative and therapeutic measures. Existing clinical interventions have limitations, such as slow recovery rates, high costs, and inefficient drug delivery methods. Therefore, exploring alternative avenues to develop effective wound-healing treatments is essential. Nature offers a vast array of resources in the form of secondary metabolites, notably polyphenols, known for their antimicrobial, anti-inflammatory, antioxidant, glucose-regulating, and cell growth-promoting properties. Additionally, nanoparticles synthesized through environmentally friendly methods hold promise for wound healing applications in diabetic and non-diabetic conditions. This review provides a comprehensive discussion and summary of the potential wound-healing abilities of specific natural polyphenols and their nanoparticles. It explores the mechanisms of action underlying their efficacy and presents effective formulations for promoting wound-healing activity.

Abstract
BACKGROUND Numerous cellular, humoral, and molecular processes are involved in the intricate process of wound healing. PHARMACOLOGICAL RELEVANCE Numerous bioactive substances, such as ß-sitosterol, tannic acid, gallic acid, protocatechuic acid, quercetin, ellagic acid, and pyrogallol, along with their pharmacokinetics and bioavailability, have been reviewed. These phytochemicals work together to promote angiogenesis, granulation, collagen synthesis, oxidative balance, extracellular matrix (ECM) formation, cell migration, proliferation, differentiation, and re-epithelialization during wound healing. FINDINGS AND NOVELTY To improve wound contraction, this review delves into how the application of each bioactive molecule mediates with the inflammatory, proliferative, and remodeling phases of wound healing to speed up the process. This review also reveals the underlying mechanisms of the phytochemicals against different stages of wound healing along with the differentiation of the in vitro evidence from the in vivo evidence There is growing interest in phytochemicals, or plant-derived compounds, due their potential health benefits. This calls for more scientific analysis and mechanistic research. The various pathways that these phytochemicals control/modulate to improve skin regeneration and wound healing are also briefly reviewed. The current review also elaborates the immunomodulatory modes of action of different phytochemicals during wound repair.

Abstract
Biodegradable aliphatic polyester formulations as carriers for topical drug delivery show the potential to encapsulate structurally different therapeutic compounds. Poly(octamethylene suberate) (POS) nanoparticles (POS-NPs) were used as a matrix to encapsulate four therapeutic molecules used to treat skin disorders: caffeine (CF), quercetin (QR), hydrocortisone (HC), and adapalene (AD). Hydrophobicity and chemical structure of bioactive compounds (BCs) influenced the physicochemical stability of drug-loaded nanoparticles. The particle size of drug-loaded nanoparticles was between 254.9 nm for the CF-POS-NP and 1291.3 for QR-POS-NP. Particles had a negative charge from -27.6 mV (QR) to -49.2 mV (HC). Drug loading content for all BC-POS-NPs varies between 36.11 ± 1.48% (CF-POS-NP) and 66.66 ± 4.87% (AD-POS-NP), and their entrapment efficiency is relatively high (28.30 ± 1.81% and 99.95 ± 0.04%, respectively). Calorimetric analysis showed the appearance of polymorphism for AD- and HC-loaded systems and the drug's complete solubilisation into all nanoparticle formulations. FTIR and NMR spectra showed apparent drug incorporation into the polymer matrix of NPs. The encapsulation of BCs enhanced the antioxidative effect. The prepared POS nanoparticles' cytotoxicity was studied using two dermal cell lines, keratinocyte (HaCaT) cells and fibroblasts (HDFn). The nanoparticle cytotoxic effect was more substantial on HaCaT cell lines. A reconstructed human epidermis (RHE) was successfully used to investigate the penetration of polymeric NPs. Based on permeation and histology studies, HC-POS-NPs and CF-POS-NPs were shown not to be suitable for dermal applications with the explored drug concentrations. AD presents a high permeation rate and no toxic impact on RHE.

Abstract
Aim The study investigated Ethion-induced developmental toxicity in Wistar albino rats and the potential ameliorative effects of quercetin and nano-quercetin co-administration. Further, In-silico docking of Ethion and quercetin with MCL-1 was conducted. Methodology Quercetin nanoparticles were synthesized by ionic-gelation method. The encapsulated quercetin nanoparticles were characterized for Zeta size, UV-Vis spectroscopy, encapsulation efficiency, and TEM studies. Male rats were administered Ethion (high/low dose), quercetin, and nano-quercetin alone or in combination for 60 days. Female rats were introduced for mating on the 61st day, and pregnant females were observed for 20 gestational days. On GD 20, rats were sacrificed and evaluated for body/organ weight, reproductive indices, fetal morphology, skeletal, and visceral deformities.In silico binding energies of ethion and quercetin with MCL-1 were determined. Results Nanoparticle size was 363.2 ± 1.23 nm on day 0 and 385.63 ± 1.53 nm on day 60, with PDI of 0.247 and charge of 22.9 mV. Absorbance maxima were at 374 nm, with encapsulation efficacy of 85.16 ± 0.33%. EHD male crossed females showed decreased body/organ weights, reduced fertility, hematoma, cleft palate, tail curling, and absence of extremity. Nano-quercetin co-administration normalized parameters comparable to controls. Both Ethion and quercetin interacted with MCL-1, with quercetin exhibiting stronger binding energy. Conclusion Nano-quercetin demonstrated stronger antioxidant properties than quercetin, counteracting ethion-induced maternal/fetal abnormalities.

Abstract
Flavonoids are widely distributed in nature and have a variety of beneficial biological effects, including antioxidant, anti-inflammatory, and anti-obesity effects. All of these are related to gut microbiota, and flavonoids also serve as a bridge between the host and gut microbiota. Flavonoids are commonly used to modify the composition of the gut microbiota by promoting or inhibiting specific microbial species within the gut, as well as modifying their metabolites. In turn, the gut microbiota extensively metabolizes flavonoids. Hence, this reciprocal relationship between flavonoids and the gut microbiota may play a crucial role in maintaining the balance and functionality of the metabolism system. In this review, we mainly highlighted the biological effects of antioxidant, anti-inflammatory and antiobesity, and discussed the interaction between flavonoids, gut microbiota and lipid metabolism, and elaborated the potential mechanisms on host lipid metabolism.

[PMID: 38308387 DOI: 10.1515/jcim-2023-0177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 01/10/2024] [Indexed: 02/04/2024]
Abstract
Wounds in diabetes is a complex problem that requires effective treatment at a high cost. Adjuvant therapy from natural bioactive elements can be an alternative to overcome problems in diabetic wound healing disorders. Allicin and quercetin are natural bioactive substances contained in several fruit or vegetable plants that have various pharmacological effects. The purpose of this study was to determine the effect of allicin and quercetin in emulsion form as wound medicine in helping the wound healing process. Diabetic wistar rats with wounds on their backs measuring 1 × 1 cm were divided into four treatment groups which were given wound medicine once a day for seven days according to their distribution. The wound healing process was evaluated on the third and seventh day. Data were observed and analyzed using appropriate statistical tools. Measurement of wound healing indicators was carried out by examining wound contraction and histopathological examination showing that the treatment group given the allicin and quercetin formula experienced an improvement compared to the treatment group without allicin and quercetin. Allicin and quercetin increase the percentage of wound contraction, increase the density of blood vessels and the epithelialization process in the wound so that the wound healing process becomes faster. In conclusion, allicin and quercetin can be effective adjuvant therapies in helping wound healing in diabetes. Wound medication in the form of an emulsion is an effective choice, because it can maintain the stability of the allicin and quercetin content and can make the wound environment moist.

Chitosan inhibits vascular intimal hyperplasia via LINC01615/MIR-185-5p/PIK3R2 signaling pathway. Gene 2024; 892:147850.

Abstract
The abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) are the main pathological processes which are involved in the formation of new intima. In our previous study, we found that chitosan can inhibit the formation of new intima in the arteriovenous fistulas of uremic patients, and the expression of LINC01615 was significantly increased in patients after treatment with chitosan. Therefore, this study aims to further explore the effect of chitosan on the intimal hyperplasia and elucidate the potential molecular mechanism. In vitro, we found that in chitosan-treated VSMC, the levels of Il-1β, IL-6 and TNF-α decreased, and the intimal hyperplasia was inhibited along with significantly downregulated PIK3R2 and upregualted PI3K, AKT and p-AKT. Meanwhile, we observed the phenotypic transformation of hVSMCs after LINC01615 was upregulated. In addition, inflammatory factors showed the same changes in the process of up-regulating LINC01615. Moreover, only in the LINC01615 overexpression and miR-185-5p mimic experimental group, the inhibition of intimal hyperplasia was the most obvious. The interaction between LINC01615 and miR-185-5p, miR-185-5p and PIK3R2 was further confirmed by the dual luciferase assay. These results suggest that chitosan has a potential preventive effect on neointimal hyperplasia and related vascular remodeling.

Abstract
Berberine-encapsulated polyelectrolyte nanocomposite (BR-PolyET-NC) gel was developed as a long-acting improved wound healing therapy. BR-PolyET-NC was developed using an ionic gelation/complexation method and thereafter loaded into Carbopol gel. Formulation was optimized using Design-Expert® software implementing a three-level, three-factor Box Behnken design (BBD). The concentrations of polymers, namely, chitosan and alginate, and calcium chloride were investigated based on particle size and %EE. Moreover, formulation characterized in vitro for biopharmaceutical performances and their wound healing potency was evaluated in vivo in adult BALB/c mice. The particle distribution analysis showed a nanocomposite size of 71 ± 3.5 nm, polydispersity index (PDI) of 0.45, ζ-potential of +22 mV, BR entrapment of 91 ± 1.6%, and loading efficiency of 12.5 ± 0.91%. Percentage drug release was recorded as 89.50 ± 6.9% with pH 6.8, thereby simulating the wound microenvironment. The in vitro investigation of the nanocomposite gel revealed uniform consistency, well spreadability, and extrudability, which are ideal for topical wound use. The analytical estimation executed using FT-IR, DSC, and X-ray diffraction (XRD) indicated successful formulation with no drug excipients and without the amorphous state. The colony count of microbes was greatly reduced in the BR-PolyET-NC treated group on the 15th day from up to 6 CFU compared to 20 CFU observed in the BR gel treated group. The numbers of monocytes and lymphocytes counts were significantly reduced following healing progression, which reached to a peak level and vanished on the 15th day. The observed experimental characterization and in vivo study indicated the effectiveness of the developed BR-PolyET-NC gel toward wound closure and healing process, and it was found that >99% of the wound closed by 15th day, stimulated via various anti-inflammatory and angiogenic factors.

Abstract
The evaluation of the efficacy of incorporation of quercetin in nanoparticles is crucial, both for the development and quality control of pharmaceutical formulations. The validation of analytical methods for the precise quantification of quercetin is useful for the evaluation of various potential quercetin delivery systems and quercetin pharmacokinetics. This work aimed to validate a high-performance liquid chromatography with diode array detection (HPLC-DAD) method for quercetin detection and quantification in nanoparticles. Different mobile phase conditions and detection wavelengths (254 and 368 nm) were tested, and the major validation parameters were assessed (precision, accuracy, linearity, sensitivity, stability, and selectivity). The best peak resolution was obtained when quercetin was analyzed at 368 nm with a mobile phase of 1.5% acetic acid and a water/acetonitrile/methanol ratio of 55:40:5. Under these conditions, quercetin also eluted rapidly (retention time of 3.6 min). The method proved to be linear (R2 > 0.995), specific, and repeatable (variation coefficient between 2.4% and 6.7%) and presented intermediate precision (variation coefficient between 7.2% and 9.4%). The accuracy of the analysis ranged between 88.6% and 110.7%, and detection and quantification limits were 0.046 and 0.14 µg/mL, respectively. Quercetin solutions were more stable when stored at 4 °C than at room temperature or -20 °C. This validated method satisfied more parameters of bias assessment than most recent methods for quercetin determination and presented itself as more sensitive and efficient than general spectrophotometric methods. The method was successfully used for the analysis of quercetin incorporation in nanoparticles and will be evaluated in the future for its adequacy for the determination of quercetin in more complex matrices.

Abstract
Aimed to clarify the effect of quercetin and its derivatives on wound healing in animal experiments. PubMed, Embase, Science Direct, Web of Science, SinoMed, Vip Journal Integration Platform, China National Knowledge Infrastructure and WanFang databases were searched for animal experiments investigating the effect of quercetin and its derivatives on wound healing to April 2023. The Review Manager 5.4 software was used to conduct meta-analysis. Eighteen studies were enrolled in this article. According to the SYRCLE's RoB tool assessment, these studies exposed relatively low methodological quality. It was shown that animals with cutaneous wound receiving quercetin had faster wound healing in wound closure (%) than the control group. Moreover, the difference in efficacy gradually emerged after third day (WMD = 7.13 [5.52, 8.74]), with a peak reached on the tenth day after wounding (WMD = 19.78 [17.82, 21.74]). Subgroup analysis revealed that quercetin for wound closure (%) was independent of the types of rats and mice, wound area and with or without diabetes. Clear conclusion was also shown regarding the external application of quercetin for wound healing (WMD = 17.77 [11.11, 24.43]). A significant reduction in the distribution of inflammatory cells occurred in the quercetin group. Quercetin could increase blood vessel density (WMD = 1.85 [0.68, -3.02]), fibroblast distribution and collagen fraction. Biochemical indicators, including IL-1β, IL-10, TNF-α, TGF-β, vascular endothelial growth factor (VEGF), hydroxyproline and alpha-smooth muscle actin (α-SMA), had the consistent results. Quercetin and its derivatives could promote the recovery of cutaneous wound in animals, through inhibiting inflammatory response and accelerating angiogenesis, proliferation of fibroblast and collagen deposition.

Abstract
OBJECTIVES Considering the prevalence of oral mucositis, we aimed to use the analgesic effects of doxepin with chitosan's antimicrobial and bio-adhesive nature to fabricate a nano-formulation for treating chemotherapy-induced oral mucositis. MATERIALS AND METHODS Nanogel was fabricated via ionic gelation and characterized. Sixty patients were randomly divided and received four different treatments for 14 days: diphenhydramine + aluminum-magnesium mouthwash (control), doxepin mouthwash (DOX MW), chitosan nanogel (CN), and doxepin/chitosan nanogel (CN + DOX). Lesions were assessed with four indices, National Cancer Institute (NCI), World Health Organization (WHO), World Conference on Clinical and Research in Nursing (WCCNR) and visual analog scale (VAS) before and 3, 7, and 14 days after interventions. Kruskal-Wallis test was used for pairwise comparison. RESULTS CN had semisolid consistency, uniform spherical shape, an average size of 47.93 ± 21.69 nm, and a zeta potential of + 1.02 ± 0.16 mV. CN + DOX reduced WHO, WCCNR, and VAS scores significantly more than the control three days after the intervention. Seven days after the intervention, CN + DOX reduced NCI and WCCNR considerably more than the control; it reduced WCCNR significantly more than CN. Fourteen days after the intervention, CN + DOX decreased NCI markedly more than the control. CONCLUSION Chitosan-based doxepin nano-formulation might be a promising alternative for routine treatments of oral mucositis.

Abstract
Quercetin is a well-known plant flavanol that exhibits multiple biological activities, including antioxidant, anti-inflammatory and anticancer activities. The role of quercetin in wound healing has been widely explored by a range of researchers in different models. However, the physicochemical properties, such as solubility and permeability, of this compound are low, which ultimately limits its bioavailability on the target site. To overcome these limitations for successful therapy, scientists have developed a range of nanoformulations that provide effective therapeutic potential. In this review, the broad mechanism of quercetin for acute and chronic wounds is covered. A compilation of recent advances on the horizon of wound healing via quercetin is incorporated with several advanced nanoformulations.

Abstract
Silicosis is a life-threatening lung fibrotic disease caused by excessive inhalation of environmental exposure to crystalline silica-containing dust, whereas achieving therapeutic cures are constrained. Antioxidation and anti-inflammation are currently recognized as effective strategies to counteract organ fibrosis. Using naturally occurring phytomedicines quercetin (Qu) has emerged in antagonizing fibrotic disorders involving oxidative stress and inflammation, but unfortunately the hydrophilicity deficiency. Herein, chitosan-assisted encapsulation of Qu in nanoparticles (Qu/CS-NPs) was first fabricated for silicosis-associated fibrosis treatment by pulmonary delivery. Qu/CS-NPs with spherical diameters of ~160 nm, demonstrated a high Qu encapsulated capability, excellent hydrophilic stability, fantastic oxidation radical scavenging action, and outstanding controlled as well as slow release Qu action. A silicosis rat model induced by intratracheal instillation silica was established to estimate the anti-fibrosis effect of Qu/CS-NPs. After intratracheal administration, CS-NPs markedly enhanced Qu anti-fibrotic therapy efficacy, accompanying the evident changes in reducing ROS and MDA production to mitigate oxidative stress, inhibiting IL-1β and TNF-α release, improving lung histological architecture, down-regulating α-SAM levels and suppressing ECM deposition, and thereby ameliorating silica-induced pulmonary fibrosis. Results manifested that the augmented antioxidant and anti-inflammatory activities of Qu by CS-NPs delivery was a result of achieving this remarkable improvement in curative effects. Combined with negligible systemic toxicity, nano-decorated Qu may provide a feasible therapeutic option for silicosis therapy.

[PMID: 36129522 DOI: 10.1007/s00403-022-02395-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 08/03/2022] [Accepted: 09/07/2022] [Indexed: 11/02/2022]
Abstract
Flavonoids are a class of plant polyphenols found in a variety of fruits, vegetables, teas, and flowers. These compounds are present in many common dietary sources, such as green tea, wine, pomegranates, and turmeric, and possess a broad spectrum of biological activity due to their unique chemical structure. Flavonoids exhibit antioxidant, anti-inflammatory, antiviral, and anticarcinogenic properties that have been widely studied as potential therapeutics for diseases ranging from Alzheimer's disease to liver disease. There is currently significant research into therapeutic benefits of flavonoids in various skin conditions as these compounds have been shown to absorb ultraviolet radiation and modulate cancer and inflammation signaling pathways. This review discusses the current research in the application of flavonoids in skin diseases (e.g., prevention of premature photoaging, prevention and treatment of skin cancer, and promotion of skin wound healing) and their proposed mechanisms to provide a basis for future basic and translational research of flavonoids as potential drugs in the prevention and treatment of skin disorders.

Abstract
Repairing the wound is a multistep process that includes the spatial and temporal synchronization of a different range of cell types to increase the speed of wound contraction, the proliferation of epithelial cells, and collagen formation. The need for proper management of acute wounds to be cured and not turned into chronic wounds is a significant clinical challenge. The traditional practice of medicinal plants in many regions of the world has been used in wound healing since ancient times. Recent scientific research introduced evidence of the efficacy of medicinal plants, their phyto-components, and the mechanisms underlying their wound-repairing activity. This review aims to briefly highlight the wound-curing effect of different plant extracts and purely natural substances in excision, incision, and burn experimental animal models with or without infection of mice, rats (diabetic and nondiabetic), and rabbits in the last 5 years. The in vivo studies represented reliable evidence of how powerful natural products are in healing wounds properly. They have good scavenging activity against Reactive oxygen species (ROS) and anti-inflammatory and antimicrobial effects that help in the process of wound healing. It is evident that incorporating bioactive natural products into wound dressings of bio- or synthetic polymers in nanofiber, hydrogel, film, scaffold, and sponge forms showed promising results in different phases of the wound-curing process of haemostasis, inflammation, growth, re-epithelialization, and remodelling.

Abstract
In the last few decades, several natural bioactive agents have been widely utilized in the treatment and prevention of many diseases owing to their unique and versatile therapeutic effects, including antioxidant, anti-inflammatory, anticancer, and neuroprotective action. However, their poor aqueous solubility, poor bioavailability, low GIT stability, extensive metabolism as well as short duration of action are the most shortfalls hampering their biomedical/pharmaceutical applications. Different drug delivery platforms have developed in this regard, and a captivating tool of this has been the fabrication of nanocarriers. In particular, polymeric nanoparticles were reported to offer proficient delivery of various natural bioactive agents with good entrapment potential and stability, an efficiently controlled release, improved bioavailability, and fascinating therapeutic efficacy. In addition, surface decoration and polymer functionalization have opened the door to improving the characteristics of polymeric nanoparticles and alleviating the reported toxicity. Herein, a review of the state of knowledge on polymeric nanoparticles loaded with natural bioactive agents is presented. The review focuses on frequently used polymeric materials and their corresponding methods of fabrication, the needs of such systems for natural bioactive agents, polymeric nanoparticles loaded with natural bioactive agents in the literature, and the potential role of polymer functionalization, hybrid systems, and stimuli-responsive systems in overcoming most of the system drawbacks. This exploration may offer a thorough idea of viewing the polymeric nanoparticles as a potential candidate for the delivery of natural bioactive agents as well as the challenges and the combating tools used to overcome any hurdles.

Abstract
Chitosan-based nanoparticles (chitosan-based nanocomposites; chitosan nanoparticles; ChNPs) are promising materials that are receiving a lot of attention in the last decades. ChNPs have great potential as nanocarriers. They are able to encapsulate drugs as well as active compounds and deliver them to a specific place in the body providing a controlled release. In the article, an overview has been made of the most frequently used preparation methods, and the developed applications in medicine. The presentation of the most important information concerning ChNPs, especially chitosan's properties in drug delivery systems (DDS), as well as the method of NPs production was quoted. Additionally, the specification and classification of the NPs' morphological features determined their application together with the methods of attaching drugs to NPs. The latest scientific reports of the DDS using ChNPs administered orally, through the eye, on the skin and transdermally were taken into account.

Improvement of Therapeutic Value of Quercetin with Chitosan Nanoparticle Delivery Systems and Potential Applications. Int J Mol Sci 2023; 24:ijms24043293.

Abstract
This paper reviews recent studies investigating chitosan nanoparticles as drug delivery systems for quercetin. The therapeutic properties of quercetin include antioxidant, antibacterial and anti-cancer potential, but its therapeutic value is limited by its hydrophobic nature, low bioavailability and fast metabolism. Quercetin may also act synergistically with other stronger drugs for specific disease states. The encapsulation of quercetin in nanoparticles may increase its therapeutic value. Chitosan nanoparticles are a popular candidate in preliminary research, but the complex nature of chitosan makes standardisation difficult. Recent studies have used in-vitro, and in-vivo experiments to study the delivery of quercetin alone or in combination with another active pharmaceutical ingredient encapsulated in chitosan nanoparticles. These studies were compared with the administration of non-encapsulated quercetin formulation. Results suggest that encapsulated nanoparticle formulations are better. In-vivo or animal models simulated the type of disease required to be treated. The types of diseases were breast, lung, liver and colon cancers, mechanical and UVB-induced skin damage, cataracts and general oxidative stress. The reviewed studies included various routes of administration: oral, intravenous and transdermal routes. Although toxicity tests were often included, it is believed that the toxicity of loaded nanoparticles needs to be further researched, especially when not orally administered.

Abstract
OBJECTEIVES The purpose of this study was to prepare an antibacterial, antioxidant, and biocompatible bilayer nanofibrous wound dressing by using electrospinning. METHODS The micromorphology and bilayer structure characteristics of the GA-Qe-PVP-PCL nanofibers were analyzed by SEM. The physicochemical characteristics were analyzed by XRD and FTIR. The uptake, mechanical properties, water contact angle, water vapor transmission and in vitro drug release were evaluated. In addition, the effect of antibacterial, antioxidant and biocompatability of the nanofibers were evaluated, respectively. RESULTS The SEM results showed that the GA-Qe-PVP-PCL nanofibers had a smooth surface, no beading phenomenon, and a prominent bilayer structure. The diameter and porosity of the drug-loading layer and waterproof support layer of the nanofibers were 842 ± 302 nm, 242 ± 50 nm, and 88.56 ± 1.67%, 94.49 ± 1.57%, respectively. Moreover, the water uptake, mechanical properties, water contact angle, and water vapor transmission showed ideal performance. The results of in vitro drug release indicated that GA and Qe were both released rapidly, which was conducive to accelerating wound healing. The GA-Qe-PVP-PCL nanofibers exhibited antibacterial effects against both bacteria as well as high antioxidant activity. Additionally, the GA-Qe-PVP-PCL nanofibers possessed good compatibility, could promote the proliferation, adhesion, and migration of L929 fibroblast cells. CONCLUSION The nanofibers we developed met the requirements of ideal materials for wound dressing, which makes the nanofibers the potential to be a wound dressing for wound care.

Abstract
Wound dressing design is a dynamic and rapidly growing field of the medical wound-care market worldwide. Advances in technology have resulted in the development of a wide range of wound dressings that treat different types of wounds by targeting the four phases of healing. The ideal wound dressing should perform rapid healing; preserve the body’s water content; be oxygen permeable, non-adherent on the wound and hypoallergenic; and provide a barrier against external contaminants—at a reasonable cost and with minimal inconvenience to the patient. Therefore, choosing the best dressing should be based on what the wound needs and what the dressing does to achieve complete regeneration and restoration of the skin’s structure and function. Biopolymers, such as alginate (ALG), chitosan (Cs), collagen (Col), hyaluronic acid (HA) and silk fibroin (SF), are extensively used in wound management due to their biocompatibility, biodegradability and similarity to macromolecules recognized by the human body. However, most of the formulations based on biopolymers still show various issues; thus, strategies to combine them with molecular biology approaches represent the future of wound healing. Therefore, this article provides an overview of biopolymers’ roles in wound physiology as a perspective on the development of a new generation of enhanced, naturally inspired, smart wound dressings based on blood products, stem cells and growth factors.

Abstract
The development of new strategies to reduce the use of traditional antibiotics has been a topic of global interest due to the resistance generated by multiresistant microorganisms, including Escherichia coli, as etiological agents of various diseases. Antimicrobial peptides are presented as an alternative for the treatment of infectious diseases caused by this type of microorganism. The Ib−M1 peptide meets the requirements to be used as an antimicrobial compound. However, it is necessary to use strategies that generate protection and resist the conditions encountered in a biological system. Therefore, in this study, we synthesized alginate and chitosan nanoparticles (Alg−Chi NPs) using the ionic gelation technique, which allows for the crosslinking of polymeric chains arranged in nanostructures by intermolecular interactions that can be either covalent or non-covalent. Such interactions can be achieved through the use of crosslinking agents that facilitate this binding. This technique allows for immobilization of the Ib−M1 peptide to form an Ib−M1/Alg−Chi bioconjugate. SEM, DLS, and FT-IR were used to determine the structural features of the nanoparticles. We evaluated the biological activity against E. coli ATCC 25922 and Vero mammalian cells, as well as the stability at various temperatures, pH, and proteases, of Ib−M1 and Ib−M1/Alg-Chi. The results showed agglomerates of nanoparticles with average sizes of 150 nm; an MIC of 12.5 µM, which was maintained in the bioconjugate; and cytotoxicity values close to 40%. Stability was maintained against pH and temperature; in proteases, it was only evidenced against pepsin in Ib−M1/Alg-Chi. The results are promising with respect to the use of Ib−M1 and Ib−M1/Alg−Chi as possible antimicrobial agents.

Abstract
In the past decades, phytoconstituents have appeared as critical mediators for immune regulations among various diseases, both in eukaryotes and prokaryotes. These bioactive molecules, showing a broad range of biological functions, would hold tremendous promise for developing new therapeutics. The discovery of phytoconstituents' capability of functionally regulating immune cells and associating cytokines, suppressing systemic inflammation, and remodeling immunity have rapidly promoted the idea of their employment as anti-inflammatory agents. In this review, we discuss various roles of phyto-derived medicines in the field of inflammatory diseases, including chronic inflammation, autoimmune diseases, and acute inflammatory disease such as COVID-19. Nevertheless, traditional phyto-derived medicines often concurred with their clinical administration limitations, such as their lack of cell specificity, inefficient cytoplasmic delivery, and rapid clearance by the immune system. As alternatives, phyto-derived nano-approaches may provide significant benefits. Both unmodified and engineered nanocarriers present the potential to serve as phytoconstituent delivery systems to improve therapeutic physio-chemical properties and pharmacokinetic profiles. Thus, the development of phytoconstituents' nano-delivery designs, their new and perspective approaches for therapeutical applications are elaborated herein.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oxytropis falcata Bunge is a legume distributed in Northwest China, which is mainly used to treat knife wounds and inflammation. Quercetin is a bioactive flavonoid in O. falcata and becomes a promising healing compound for its angiogenic and anti-inflammatory activities. However, the healing mechanism of quercetin in cutaneous wound remains elusive. AIM OF THE STUDY The purpose of this study was to evaluate the healing effect of quercetin on cutaneous wound models in vivo and in vitro, and to reveal the Wnt/β-catenin pathway and Telomerase reverse transcriptase (TERT) involved mechanisms. MATERIALS AND METHODS The effects of quercetin on the proliferation and migration of 4 kinds of skin cells were determined by CCK-8 and scratch assay. The wound-healing capacity of quercetin was evaluated in cutaneous wound model of C57BL/6 mice and the wound healing degree was observed by histological staining. The expressions of inflammatory factors, growth factors and the related proteins were detected via Western blot and RT-qPCR analyses. The molecular docking was adopted to evaluate the binding ability of quercetin and TERT. RESULTS Quercetin could promote both proliferation and migration of fibroblasts, and enhance cutaneous wound healing capacity in mice. Compared to the control group, the wound healing rates in low (1.5 mg/mL), medium (3.0 mg/mL) and high dose (6.0 mg/mL) quercetin groups reached 94.67%, 97.31% and 98.42%, respectively. Moreover, the dermal structure in quercetin treated mice restored normal and the content of collagen fiber became abundant after administration. The levels of inflammatory factors, including tumor necrosis factor-α, interleukin-1β and interleukin-6 were significantly reduced after quercetin administration. Among which, the level of IL-1β in cutaneous wound was 0.007 times higher than that of the control group when treated with quercetin of high dose (6.0 mg/mL). The improved level of GSH in quercetin treated cutaneous wounds also indicated its higher antioxidant ability. In addition, dose-dependent positive associations were found in the expression levels of vascular endothelial growth factor, fibroblast growth factor and alpha smooth muscle actin in quercetin treated cutaneous wounds. The significantly upregulated protein levels of Wnt and β-catenin further indicated the important role of quercetin in promoting wound healing in mice. According to molecular docking analysis, the formed hydrogen bonds between quercetin and Ala195, Gln308, Asn369 and Lys372 residues of TERT also indicated the indispensable role of TERT in improving wound healing capacity. CONCLUSION Quercetin effectively promoted cutaneous wound healing by enhancing the proliferation and migration of fibroblasts, as well as inhibiting inflammation and increasing the expression of growth factors in mice via Wnt/β-catenin signaling pathway and TERT. It provides a basis for a more thorough understanding of mechanism of action of O. falcata Bunge in the treatment of knife wounds and burns.

Abstract
Various studies, especially in recent years, have shown that quercetin has beneficial therapeutic effects in various human diseases, including diabetes. Quercetin has significant anti-diabetic effects and may be helpful in lowering blood sugar and increasing insulin sensitivity. Quercetin appears to affect many factors and signaling pathways involved in insulin resistance and the pathogenesis of type 2 of diabetes. TNFα, NFKB, AMPK, AKT, and NRF2 are among the factors that are affected by quercetin. In addition, quercetin can be effective in preventing and ameliorating the diabetic complications, including diabetic nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy, and affects the key mechanisms involved in the pathogenesis of these complications. These positive effects of quercetin may be related to its anti-inflammatory and anti-oxidant properties. In this article, after a brief review of the pathogenesis of insulin resistance and type 2 diabetes, we will review the latest findings on the anti-diabetic effects of quercetin with a molecular perspective. Then we will review the effects of quercetin on the key mechanisms of pathogenesis of diabetes complications including nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy. Finally, clinical trials investigating the effect of quercetin on diabetes and diabetes complications will be reviewed.

Food-Derived Bioactive Molecules from Mediterranean Diet: Nanotechnological Approaches and Waste Valorization as Strategies to Improve Human Wellness. Polymers (Basel) 2022; 14:polym14091726. [PMID: 35566894 PMCID: PMC9103748 DOI: 10.3390/polym14091726] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/15/2022] [Accepted: 04/21/2022] [Indexed: 02/04/2023] Open
Abstract
The beneficial effects of the Mediterranean diet (MedDiet), the most widely followed healthy diet in the world, are principally due to the presence in the foods of secondary metabolites, mainly polyphenols, whose healthy characteristics are widely recognized. However, one of the biggest problems associated with the consumption of polyphenols as nutraceutical adjuvant concerns their bioavailability. During the last decades, different nanotechnological approaches have been developed to enhance polyphenol bioavailability, avoiding the metabolic modifications that lead to low absorption, and improving their retention time inside the organisms. This review focuses on the most recent findings regarding the encapsulation and delivery of the bioactive molecules present in the foods daily consumed in the MedDiet such as olive oil, wine, nuts, spice, and herbs. In addition, the possibility of recovering the polyphenols from food waste was also explored, taking into account the increased market demand of functional foods and the necessity to obtain valuable biomolecules at low cost and in high quantity. This circular economy strategy, therefore, represents an excellent approach to respond to both the growing demand of consumers for the maintenance of human wellness and the economic and ecological exigencies of our society.

Loo HL, Goh BH, Lee LH, Chuah LH. Application of chitosan nanoparticles in skin wound healing. Asian J Pharm Sci 2022; 17:299-332. [PMID: 35782330 PMCID: PMC9237591 DOI: 10.1016/j.ajps.2022.04.001] [Citation(s) in RCA: 57] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 03/31/2022] [Accepted: 04/01/2022] [Indexed: 12/25/2022] Open
Abstract
The rising prevalence of impaired wound healing and the consequential healthcare burdens have gained increased attention over recent years. This has prompted research into the development of novel wound dressings with augmented wound healing functions. Nanoparticle (NP)-based delivery systems have become attractive candidates in constructing such wound dressings due to their various favourable attributes. The non-toxicity, biocompatibility and bioactivity of chitosan (CS)-based NPs make them ideal candidates for wound applications. This review focusses on the application of CS-based NP systems for use in wound treatment. An overview of the wound healing process was presented, followed by discussion on the properties and suitability of CS and its NPs in wound healing. The wound healing mechanisms exerted by CS-based NPs were then critically analysed and discussed in sections, namely haemostasis, infection prevention, inflammatory response, oxidative stress, angiogenesis, collagen deposition, and wound closure time. The results of the studies were thoroughly reviewed, and contradicting findings were identified and discussed. Based on the literature, the gap in research and future prospects in this research area were identified and highlighted. Current evidence shows that CS-based NPs possess superior wound healing effects either used on their own, or as drug delivery vehicles to encapsulate wound healing agents. It is concluded that great opportunities and potentials exist surrounding the use of CSNPs in wound healing.
