Multifunctional (4-in-1) Therapeutic Applications of Nickel Thiocyanate Nanoparticles Impregnated Cotton Gauze as Antibacterial, Antibiofilm, Antioxidant and Wound Healing Agent.

The wounds, arises from accidents, burns, surgeries, diabetes, and trauma, can significantly impact well-being and present persistent clinical challenges. Ideal wound dressings should be flexible, stable, antibacterial, antioxidant and anti-inflammatory in nature, facilitating a scarless rapid wound healing. Initiatives were taken to create antibacterial cotton fabrics by incorporating agents like antibiotics and metallic nanoparticles. However, due to a lack of multifunctionality, these materials were not highly effective in causing scarless and rapid wound healing. In this article, nickel thiocyanate nanoparticle (NiSCN-NPs) impregnated cotton gauze wound dressing (NiSCN-CG) was developed. These nanoparticles were non-toxic to normal human cell lines till 1 mg/mL dose and did not cause skin irritation in the rat model. Further, NiSCN-NPs exhibited antimicrobial, antibiofilm and antioxidant activities confirmed using different in vitro experiments. In vivo wound healing studies in rat models using NiSCN-CG demonstrated rapid scarless wound healing. The nickel thiocyanate impregnated cotton gauze presents a novel approach in scarless wound healing, and as an antimicrobial agent, offering a promising solution for diverse wounds and infections in the future.

Fe-doped herbal medicine-based carbon dots nanozyme as safe and effective antimicrobial and wound healing agent

Bacterial infections pose a serious worldwide public health concern and play an important role in slowing or dramatically delaying wound healing. However, traditional antibiotics are faced with obstacles such as bacterial resistance and unsatisfactory biocompatibility, which has impeded further clinical translation. In recent years, antimicrobial nanomaterials have emerged as viable alternatives for combating bacterial infections, and carbon dots (CDs) have received particularly widespread attention due to their superior characteristics. In this work, a simple and eco-friendly one-step hydrothermal method was employed using the natural herbal medicine Eucommia ulmoides as a biomass carbon source to synthesize an Fe-doped CDs nanozyme (Fe-CDs) with good peroxidase-like (POD-like) activity, high biocompatibility, and strong antimicrobial activity for safe and effective antimicrobial therapy and the promotion of wound healing. L929 cells co-cultured with Fe-CDs did not show significant cytotoxicity and favored cell proliferation at appropriate concentrations. In addition, Fe-CDs catalyzed the decomposition of low-concentration H2O2 to ·OH, leading to enhanced antimicrobial activity. Both in vitro and in vivo experiments demonstrated that Fe-CDs exhibit potent antibacterial properties, the ability to promote cell migration and angiogenesis, and significant potential for promoting the healing of infected wounds. In summary, a green and safe antimicrobial nanozyme based on a biomass herbal medicine was developed in this work, offering promising insight into the development of novel antimicrobial materials and tissue regeneration engineering.

A Standardized Porcine Model for Partial-Thickness Wound Healing Studies: Design, Characterization, Model Validation, and Histological Insights.

Wound healing is a complex process that is still not fully understood despite extensive research. To address this, we aimed to design and characterize a standardized porcine model for the evaluation of wound healing, dressings, cell therapies, and pharmaceutical agents. Using a standardized approach, we examined the wound healing process in 1.2 mm-deep dermatome wounds at defined positions in 11 female pigs. Unlike previous studies that have only described/analyzed selected punch biopsies, we performed and described histological analyses along the complete wound length using quantitative morphometric methods. All animals remained fully healthy following surgery and showed no signs of infection. Our histopathological evaluation using a predetermined grading score and quantitative manual morphometry demonstrated the impact of different tissue sampling methods, sampling sites, and residual dermis thickness on wound healing. Our study presents a reproducible model for wound healing evaluation and demonstrates the usefulness of porcine models for assessing dermal and epidermal wound healing. The use of histological analyses over the complete wound length provides advantages over previous studies, leading to the possibility of a deeper understanding of the wound healing process. This model could potentially facilitate future research on novel wound dressings and local wound healing therapies.

Inhibiting miR-618 Promotes Keratinocytes Proliferation and Migration to Enhance Wound Healing in Mice.

The delay in wound healing caused by chronic wounds or pathological scars is a pressing issue in clinical practice, imposing significant economic and psychological burdens on patients. In particular, with the aging of the population and the increasing incidence of diseases such as diabetes, impaired wound healing is one of the growing health problems. MicroRNA (miRNA) plays a crucial role in wound healing and regulates various biological processes. Our results show that miR-618 was significantly upregulated during the inflammatory phase of wound healing.Subsequently, miR-618 promotes the secretion of pro-inflammatory cytokines and regulates the proliferation and migration of keratinocytes. Mechanistically, miR-618 binds to the target gene-Atp11b and inhibits the PI3K-Akt signaling pathway, inhibiting the epithelial-mesenchymal transition (EMT) of keratinocytes. In addition, the PI3K-Akt signaling pathway induces the enrichment of nuclear miR-618, and miR-618 binds to the promoter of Lin7a to regulate gene transcription. Intradermal injection of miR-618 antagomir around full-thickness wounds in peridermal mice effectively accelerates wound closure compared to control. In conclusion, miR-618 antagomir can be a potential therapeutic agent for wound healing.

Exploring the utilitarian aspects of a noxious exotic weed, Lantana camara: From green synthesized nanoparticles to a new frontier in biomedical innovation

The quest for potent wound healing agents has prompted the exploration of nanotechnology, particularly the use of nanoparticles synthesized via green methods. There is a growing need to create appropriate wound dressing material with exceptional features, such as antibacterial activity, biocompatibility, free radical scavenging capacity, and more, to effectively treat chronic wounds. The leaf extract of Lantana camara (LC), an invasive exotic weed is utilized in this research to produce silver nanoparticles (LC-AgNPs) and zinc oxide nanoparticles (LC-ZnONPs) in an ecologically sustainable manner with a special emphasis on their wound healing applications. Different analytical techniques were employed to characterize the biogenic nanoparticles that were synthesized, such as UV-VIS, XRD, SEM EDAX and TEM. The UV–visible absorbance peaks at 450 nm and 370 nm, respectively, confirmed the nanoscale presence of silver and zinc oxide particles. X-ray diffraction analysis demonstrated that the particles were exceptionally crystalline. Analysis by energy-dispersive X-ray confirmed the presence of ZnO and silver nanoparticles of high purity. The antibacterial and antifungal activities of LC-Ag NPs and LC-ZnONPs against Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923), Aspergillus niger (ATCC 16404), and Candida albicans (ATCC 10231) were evaluated using the disc diffusion method. The remarkable efficacy exhibited by the synthesized particles against bacteria and fungi suggests that they may find utility in antimicrobial and antifungal applications. ZnO nanoparticles also exhibited excellent antioxidant activity. The LC50 value of 42.58 μg/mL for LC-AgNPs is significantly lower than that of 79.66 μg/mL for LC-ZnONPs, as determined by cytotoxicity studies. This discrepancy suggests that LC-ZnONPs may be a more suitable material for applications involving wound healing in a cost-effective manner. This research highlights the revolutionary effects of nanotechnology in the field of biomedicine and illustrates an environmentally benign, economical, and sustainable use of L. camara.

Pharmacological effects of bioactive agents in earthworm extract: A comprehensive review.

This review compiles information from the literature on the chemical composition, pharmacological effects, and molecular mechanisms of earthworm extract (EE) and suggests possibilities for clinical translation of EE. We also consider future trends and concerns in this domain. We summarize the bioactive components of EE, including G-90, lysenin, lumbrokinase, antimicrobial peptides, earthworm serine protease (ESP), and polyphenols, and detail the antitumor, antithrombotic, antiviral, antibacterial, anti-inflammatory, analgesic, antioxidant, wound-healing, antifibrotic, and hypoglycemic activities and mechanisms of action of EE based on existing invitro and invivo studies. We further propose the potential of EE for clinical translation in anticancer and lipid-modifying therapies, and its promise as source of a novel agent for wound healing and resistance to antibiotic tolerance. The earthworm enzyme lumbrokinase embodies highly effective anticoagulant and thrombolytic properties and has the advantage of not causing bleeding phenomena due to hyperfibrinolysis. Its antifibrotic properties can reduce the excessive accumulation of extracellular matrix. The glycolipoprotein extract G-90 can effectively scavenge reactive oxygen groups and protect cellular tissues from oxidative damage. Earthworms have evolved a well-developed defense mechanism to fight against microbial infections, and the bioactive agents in EE have shown good antibacterial, fungal, and viral properties in invitro and invivo experiments and can alleviate inflammatory responses caused by infections, effectively reducing pain. Recent studies have also highlighted the role of EE in lowering blood glucose. EE shows high medicinal value and is expected to be a source of many bioactive compounds.

Symphytum genus—from traditional medicine to modern uses: an update on phytochemistry, pharmacological activity, and safety

AbstractWith around 34 recognized species, Symphytum genus (comfrey) has a noteworthy position within the Boraginaceae family. Comfrey species have been empirically used since ancient times as wound-healing and skin-regenerating agents in ulcers, wounds, bone fractures, and rheumatic complaints. This review aims to provide a thorough examination of recent scientific advances and challenges within the Symphytum genus, covering data published between 2013 and 2023. It delivers an updated overview of the taxonomy, ethnopharmacological uses, chemical composition, and pharmacological activities of the genus. Special emphasis is put on molecular identification methods for species taxonomy, emerging extraction technologies for comfrey phytochemicals, metabolomics techniques for mapping chemical complexity, modern bioassay platforms revealing its poly-pharmacology, formulation strategies, and remediation approaches for removal of toxic pyrrolizidine alkaloids (PAs). For instance, recent metabolomic studies employing advanced spectro-chromatographic techniques have revealed a diverse chemical composition of comfrey plants, including polysaccharides, allantoin, benzoic and cinnamic acid derivatives, flavonoids, fatty acids, and unsaturated necine-structure-based PAs. The mechanisms underlying their anti-inflammatory, analgesic, wound-healing, anti-irritant, and osteo-regenerative properties were targeted in modern pharmacological setups. Thus, key compounds like allantoin, rosmarinic acid, globoidnans A and B, rabdosiin, and comfreyn A, have been identified as significant contributors to the anti-inflammatory and wound-healing effects of Symphytum-derived preparations. Despite their well-established clinical use, concerns about PAs-induced toxicity have prompted the development of novel PA remediation strategies, enabling the production of comfrey extracts with enhanced safety profiles that can meet the regulatory standards imposed by authorities.

A suction blister model to characterize epidermal wound healing and evaluate the efficacy of the topical wound healing agent INM-755 in healthy volunteers.

Non-healing wounds represent a substantial medical burden with few effective treatments available. To address this challenge, we developed a novel epidermal wound healing model using suction blisters in healthy volunteers. This model allowed for the comprehensive assessment of wound healing dynamics and the evaluation of INM-755, a topical cream containing cannabinol, as a potential therapeutic agent. Two clinical studies were conducted: an observational study and an interventional study. In both studies, healthy volunteers underwent a suction blister procedure on their lower back, creating open epidermal wounds. Wound healing parameters were assessed using advanced imaging systems. Skin barrier function and perfusion were evaluated through trans epidermal water loss (TEWL) and dynamic optical coherence tomography (D-OCT), respectively. The observational study demonstrated the successful and reproducible induction of blisters and the removal of epidermal sheet, enabling quantifiable measurements of wound healing parameters over time. Re-epithelialization was observed, revealing recovery of skin barrier function and perfusion. In the interventional study, differences of treatments over time were quantified using the above-described techniques. Despite differences from disease-specific blistering, our developed model provides a valuable platform for studying wound healing mechanisms and assessing novel therapeutic interventions. The sensitivity to treatment effects demonstrated in our study underscores the potential utility of this model in early-phase clinical drug development programs targeting wound healing disorders.

Design and Characterisation of Curcumin-Loaded Nanostructured Lipid Carriers for Safe and Efficient Topical Drug Delivery in The Treatment of Pressure Ulcer

Pressure ulcers (PU) are chronic lesions with a high prevalence in at-risk populations. Although curcumin has various therapeutic properties, its use as a dermal therapeutic agent is limited by its poor solubility and permeability. This study aimed to develop nanostructured lipid carriers (NLCs) to facilitate the topical use of curcumin as wound healing agent in treating PU. The optimised curcumin-NLCs were characterised for their physicochemical properties, drug release, and skin permeation, while effectiveness and toxicity were investigated via cell viability, scratch assays, and an in vivo skin irritation test. The optimised curcumin-NLCs comprised 3.5% solid lipids, 1% surfactant, and 2% co-surfactant with an average particle size of 134.68±6.0 nm, polydispersity index of 0.248±0.00, zeta potential of −44.94±5.44, percentage of encapsulation efficiency of 93.42±0.32%, and drug loading of 0.11±0.00%. Curcumin-NLCs showed stable physicochemical properties and extended drug release for up to 48 h, with a cumulative release of 77.72% following a first-order kinetics. The formulation exhibited slower curcumin permeation than the free curcumin. Furthermore, the safe and non-toxic curcumin-NLCs were highly effective at 0.98 μM and showed a high rate of wound closure without skin irritation. Collectively, the NLCs developed for topical delivery of curcumin demonstrated prolonged and sustained release and improved wound healing activity, which indicates that curcumin-NLCs are a viable strategy for treating PU.

The Potential Activity of Kecombrang (Etlingera elatior) Leaf, Flower, and Stem Extracts on the Duration of Wound Healing in Mice (Mus musculus)

Wound is skin tissue damage due to trauma from a sharp object. Kecombrang flower extract is known to be effective in speeding up the healing of wounds because it contains flavonoids, saponins, tannins and steroids. The leaves and stems also contain these compounds, so this research was conducted to see the difference in the potential activity of the wound healing process of the kecombrang plant on the time of wound healing. Natural ingredient extracts are wound healing agents that can fight infection and speed up wound healing. This study used 5 treatment groups consisting of control (-) distilled water, control (+) Povidone Iodine 10 %, leaf extract 10 %, flower extract 10 %, and stem extract 10 %. The parameters observed were the length of the wound and the condition of the wound until the wound healed. The obtained data were analyzed statistically using ANOVA for complately randomized factorial designed. The results of the research show that extracts of kecombrang leaves, flowers, and stems have activity in accelerating the healing process of cut wounds and produce different effects on healing time. Wound healing time for leaf extract is 12 days, flower extract and stem extract is 10 days. The conclusion of this study shows that there is a very real difference in wound healing from treatment with the best treatment for wound healing is the flower extract with highest healing score of 6.42.

Mesoporous Oxidized Mn-Ca Nanoparticles as Potential Antimicrobial Agents for Wound Healing.

Managing chronic non-healing wounds presents a significant clinical challenge due to their frequent bacterial infections. Mesoporous silica-based materials possess robust wound-healing capabilities attributed to their renowned antimicrobial properties. The current study details the advancement of mesoporous silicon-loaded MnO and CaO molecules (HMn-Ca) against bacterial infections and chronic non-healing wounds. HMn-Ca was synthesized by reducing manganese chloride and calcium chloride by urotropine solution with mesoporous silicon as the template, thereby transforming the manganese and calcium ions on the framework of mesoporous silicon. The developed HMn-Ca was investigated using scanning electron microscopy (SEM), transmission electron microscope (TEM), ultraviolet-visible (UV-visible), and visible spectrophotometry, followed by the determination of Zeta potential. The production of reactive oxygen species (ROS) was determined by using the 3,3,5,5-tetramethylbenzidine (TMB) oxidation reaction. The wound healing effectiveness of the synthesized HMn-Ca is evaluated in a bacterial-infected mouse model. The loading of MnO and CaO inside mesoporous silicon enhanced the generation of ROS and the capacity of bacterial capture, subsequently decomposing the bacterial membrane, leading to the puncturing of the bacterial membrane, followed by cellular demise. As a result, treatment with HMn-Ca could improve the healing of the bacterial-infected wound, illustrating a straightforward yet potent method for engineering nanozymes tailored for antibacterial therapy.

Double-modified, thio and methylene ATP analogue facilitates wound healing in vitro and in vivo

Recent data indicate that extracellular ATP affects wound healing efficacy via P2Y2-dependent signaling pathway. In the current work, we propose double-modified ATP analogue—alpha-thio-beta,gamma-methylene-ATP as a potential therapeutic agent for a skin regeneration. For the better understanding of structure–activity relationship, beside tested ATP analogues, the appropriate single-modified derivatives of target compound, such as alpha-thio-ATP and beta,gamma-methylene-ATP, were also tested in the context of their involvement in the activation of ATP-dependent purinergic signaling pathway via the P2Y2 receptor. The diastereomerically pure alpha-thio-modified-ATP derivatives were obtained using the oxathiaphospholane method as separate SP and RP diastereomers. Both the single- and double- modified ATP analogues were then tested for their impact on the viability and migration of human keratinocytes. The involvement of P2Y2-dependent purinergic signaling was analyzed in silico by molecular docking of the tested compounds to the P2Y2 receptor and experimentally by studying intracellular calcium mobilization in the human keratinocytes HaCaT. The effects obtained for ATP analogues were compared with the results for ATP as a natural P2Y2 agonist. To confirm the contribution of the P2Y2 receptor to the observed effects, the tests were also performed in the presence of the selective P2Y2 antagonist—AR-C118925XX. The ability of the alpha-thio-beta,gamma-methylene-ATP to influence cell migration was analyzed in vitro on the model HaCaT and MDA-MB-231 cells by wound healing assay and transwell migration test as well as in vivo using zebrafish system. The impact on tissue regeneration was estimated based on the regrowth rate of cut zebrafish tails. The in vitro and in vivo studies have shown that the SP-alpha-thio-beta,gamma-methylene-ATP analogue promotes regeneration-related processes, making it a suitable agent for enhance wound healing. Performed studies indicated its impact on the cell migration, induction of epithelial–mesenchymal transition and intracellular calcium mobilization. The enhanced regeneration of cut zebrafish tails confirmed the pro-regenerative activity of this ATP analogue. Based on the performed studies, the SP-alpha-thio-beta,gamma-methylene-ATP is proposed as a potential therapeutic agent for wound healing and skin regeneration treatment.

Efficacy of a Novel Nanohydrogel Formulation Containing Dopamine, Chitosan Nanoparticles, and Tridax procumbens Extract for Enhanced Wound Healing in Human Gingival Fibroblast Cells: An In Vitro Study.

Background Natural compounds and biomaterials, such as nanohydrogels, have gained interest due to their biocompatibility and tissue regeneration potential. A novel nanohydrogel was prepared by employing Tridax procumbens, a traditional plant with anti-inflammatory properties and chitosan nanoparticles and a natural bioadhesive with potent antimicrobial and antioxidant effects and dopamine, which has been shown to regulate angiogenesis and influence cell growth. The objective of this study was to examine how human gingival fibroblast (HGF) cells respond to a nanohydrogel formulation containing dopamine, chitosan nanoparticles, and T. procumbens extract in terms of cell viability and cell migration. Methods From human gingival tissue, fibroblasts were cultured. A nanohydrogel formulation was prepared by combining dopamine, chitosan nanoparticles, and T. procumbens extract. Three groups were evaluated: Group 1 (nanohydrogel containing dopamine, chitosan nanoparticles, and T. procumbens extract (DnCTP)), Group 2 (chitosan nanoparticles and T. procumbens extract (nCTP)), and Group 3(T. procumbens extract (TP)). The MTT assay was used to measure the percentage of cell viability and a scratch assay to observe cell migration in the wounded area at different concentrations. The data were tabulated in Microsoft Excel (Microsoft Corporation, USA) and imported to IBM SPSS Statistics for Windows, version 23.0 (released 2015, IBM Corp., Armonk, NY), and the Mann-Whitney U test was conducted to statistically analyze the cell viability for different concentrations within the three groups. Results The nanohydrogel formulation (DnCTP) showed dose-dependent effects on cell viability with the highest cell viability at 40 µL/mL concentration, and higher concentrations of 80 µL/mL exhibited cytotoxic effects. nCTP and TP showed decreased cell viability at 80 µL/mL concentration(p < 0.05), indicating potential cytotoxicity at higher concentrations. DnCTP showed improved cell migration in the scratch assay as compared to other groups (nCTP and TP), indicating its potential for facilitating wound healing. Conclusion Dopamine, chitosan nanoparticles, and T. procumbens worked together synergistically to create a nanohydrogel formulation (DnCTP) that showed promise for improving wound healing in human gingival fibroblast cells at a dose-dependent concentration, which may therefore work as an excellent wound-healing agent in periodontal and peri-implant therapy.
