Abstract
Wound management is a critical aspect of healthcare, necessitating continuous monitoring and timely interventions to ensure optimal healing outcomes. In recent years, the integration of sensor technology into wound dressings has emerged as a transformative approach, enabling real-time monitoring of healing parameters and facilitating on-demand treatment delivery. Sensor-based wound dressings leverage various sensing modalities, including temperature, pH, moisture, oxygen, and other biochemical markers, to provide comprehensive insights into the wound microenvironment. These dressings are equipped with miniaturized sensors capable of transmitting the data wirelessly, facilitating remote monitoring and timely interventions. Moreover, some advanced dressings incorporate responsive drug delivery systems, enabling the on-demand release of therapeutics based on real-time sensor feedback. Additionally, the incorporation of on-demand treatment mechanisms allows targeted delivery of therapeutics based on the specific needs of the wound, further enhancing the efficacy of the healing process. This comprehensive approach improves patient outcomes by promoting faster and more effective wound healing and reducing the burden through streamlined monitoring and treatment protocols. This paper presents an overview of recent advancements in sensor technology applied to wound healing, focusing on their role in monitoring wound parameters and delivering targeted therapy. These sensors leverage temperature, pH, and glucose sensing modalities to provide comprehensive insights into the healing process.

Abstract
While every wound has the potential to become chronic, the risk is significantly higher in individuals with specific medical conditions. Given this inherent risk, continuous wound monitoring patches are beneficial for all wound types throughout the healing process, enabling the early detection and management of chronic wound development. In this work, we introduce an eco-friendly, hydrogel-integrated, capillary-driven wound patch designed for continuous pH monitoring. The hydrogel, synthesized from methacrylated chitosan and methacrylated poly(vinyl alcohol), provides antibacterial properties, tissue adhesion, and moisture retention, thereby supporting stable electrochemical pH detection. A paper-based, capillary-driven microfluidic layer facilitates fluid transport toward an evaporation pad, enhancing liquid uptake by approximately 4-fold after 2 h compared to the hydrogel alone. In vitro experiments demonstrated that the hydrogel-integrated sensor effectively monitored pH, exhibiting a near-linear voltage response of 16.92 mV per pH unit. The implementation of such a wound dressing represents a significant advancement in wound healing applications, combining functionality with environmental sustainability.

Abstract
BACKGROUND Over the recent years, the investigations on wound dressings have been undergoing significant evolution, and now smart dressings with the function of the real-time monitoring of the wound states have been recognized as one of the most advanced treatment modalities. Among a variety of wound-related biomarkers, pH represents a promising candidate for in situ supervising the wound healing status. In this regard, a variety of optically pH sensing agents have been widely incorporated into different types of wound dressings. RESULTS Herein, we first presented an overview of the advanced wound dressings, especially those commonly used in wound pH sensing. Then, a comprehensive summary of the optical pH sensing agents that could be incorporated into the wound dressings for detecting the pH alteration on the wound bed was described in detail. These materials were classified into colorimetric dyes (i.e., synthetic and plant-based dyes) and fluorescent probes (i.e., small-molecular fluorescein and fluorescent nanomaterials). Each type of pH sensing agent was fully discussed with advantages and limitations for monitoring the wound pH alteration, as well as typical examples of practical applications. To well interpret messages produced by the color-coding dressings, the approaches for defining and communicating color were also summarized, and a proof-of-concept, the smartphone-based remote supervision was particularly highlighted. SIGNIFICANCE This review provides a comprehensive overview of the utilization of optically pH sensing in advanced wound dressings for the real-time monitoring of the wound states. It was expected to be an informative source for the exploitation of novel diagnostic dressings for wound management, and also a reference the for application of these materials in the biosensing of other physiological or pathological fluids.

Abstract
AIM This study aimed to evaluate the safety and efficacy of combined photodynamic therapy (PDT) and photobiomodulation (PBM) in treating sickle cell leg ulcers (SCLUs), with a focus on pain reduction and enhanced healing. MATERIALS AND METHODS In this prospective, open-label, uncontrolled pilot study, ten SCD patients with 17 chronic leg ulcers received PDT and PBM treatments. Ulcer severity, pain levels, and microbiome changes were monitored, and clinical data were analyzed using appropriate statistical methods. RESULTS Among the treated ulcers, 64.7 % (11 out of 17) showed significant healing, with 9 ulcers achieving complete closure. The average reduction in ulcer size was significant, with a median healing time of 123 days. Pain levels decreased significantly in 82.3 % of treated ulcers (p < 0.001), and a 75.4 % reduction in bacterial load was observed, alongside increased microbiome diversity (p < 0.05). Elevated levels of IL-6 and PSGL-1 were associated with non-healing ulcers, indicating their potential as prognostic biomarkers. CONCLUSION The combined PDT and PBM therapy proved to be effective and safe for SCLUs, offering significant improvements in healing and pain reduction. These findings suggest that integrating PDT and PBM into standard care protocols could enhance the management of SCLUs.

Abstract
Objective: The healing process following connective tissue (CT) injuries is complex, resulting in variable and often suboptimal outcomes. Patients undergoing CT repair frequently experience healing failures, compromised function, and chronic degenerative diseases. The identification of biomarkers to guide improved clinical outcomes after CT injuries remains an emerging but promising field. [Figure: see text] [Figure: see text] Design: Systematic review. Data sources: Databases, including PubMed, MEDLINE Ovid, Web of Science, and Google Scholar, were searched up to August 2024. Eligibility criteria: To achieve the research objective, randomized control trials, cohort studies, and case-control studies on biomarkers associated with CT repair and healing outcomes were selected. The present analysis was confined to clinical and preclinical models, excluding imaging studies. The entire process of this systematic review adhered strictly to the guidelines outlined in the Preferred Reporting Items for Systematic Review and Meta-Analyses protocol checklist. Results: A total of 1,815 studies on biomarkers of CT repair were initially identified, with 75 studies meeting eligibility criteria and 55 passing quality assessments. For biomarkers associated with CT healing outcomes, 281 studies were considered, with 30 studies meeting eligibility criteria and 24 passing quality assessments. Twenty-one overlapping studies investigated the effects of biomarkers on both CT repair and healing outcomes. Specific biomarkers identified, and ranked from highest to lowest quality, include complement factor D, eukaryotic elongation factor-2, procollagen type I N-terminal propetide, procollagen type III N-terminal propetide, lactate, pyruvate, platelet-derived growth factor-BB, tissue inhibitor of metalloproteinase-3 (TIMP-3), cysteine-rich protein-1, plastin-3, periostin, protein S100-A11, vimentin, matrix metalloproteinases (MMP-2, MMP-7, and MMP-9), hepatocyte growth factor, interferon-γ, interleukins (IL-6, IL-8, and IL-10), MMP-1, MMP-3, tumor necrosis factor-α, fibroblast growth factor-2, IL-1α, chondroitin-6-sulfate, inter-alpha-trypsin inhibitor heavy chain-4, transforming growth factor-beta 1, vascular endothelial growth factor, C-C chemokine receptor 7, C-C chemokine ligand 19, IL-1β, IL-1Ra, IL-12p40, granulocyte-macrophage colony-stimulating factor (GM-CSF), and TIMP-1. Conclusions: All of the 37 identified potential biomarkers demonstrated regulatory effects on CT repair and mediated healing outcomes. Notably, the identified biomarkers from human studies can potentially play an essential role in the development of targeted treatment protocols to counteract compromised healing and can also serve as predictors for detecting CT healing processes and long-term outcomes.

Evaluating and comparing the effects of paracetamol and ibuprofen on wound healing, MMP-9, and TGF-β1 levels in patients following upper third molar tooth extraction. BMC Oral Health 2025; 25:484. [PMID: 40181349 PMCID: PMC11969977 DOI: 10.1186/s12903-024-04916-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Accepted: 09/16/2024] [Indexed: 04/05/2025] Open
Abstract
BACKGROUND Paracetamol and ibuprofen are commonly prescribed pain relievers used in dental treatments, but their use can delay wound healing and lead to malunion and weaken the strength of newly formed bones. This randomized controlled clinical trial aimed to evaluate the wound healing (WH) and anti-inflammatory effects of paracetamol and ibuprofen on tooth extraction wounds in patients. METHODS This study involved a total of 20 patients who required removal of their fully erupted upper third molar under local anaesthesia at the Oral and Maxillofacial Surgery Clinic, Faculty of Dentistry, Chiang Mai University. The study subjects were divided into two groups of 10 patients each who were prescribed 400 mg of ibuprofen or 500 mg of paracetamol for seven days. Subsequently, WH was evaluated and the resulting proportions were compared using Landry Turnbull and Howley Index (LTHI) scores. Salivary matrix metalloproteinase 9 (MMP-9) and transforming growth factor beta1 (TGF-β1) concentrations were used as proinflammatory indicators. Accordingly, the WH values and the resulting proportions were compared using Fisher's exact test with a confidence interval (CI) of 95% (P < 0.05). The concentrations of MMP-9 and TGF-β1 were measured using ELISA and compared using the Mann‒Whitney U test at 95% CI (P < 0.05). The obtained statistical values were then analysed and interpreted accordingly. RESULTS LTHI values on days 3 and 7 after tooth extraction were not significantly different between the two treatment groups. Salivary MMP-9 levels were lower in the paracetamol-treated group than in the ibuprofen-treated group (P < 0.01) on day 3 only. The LTHI concentration was also negatively correlated (r = -0.433) with the MMP-9 concentration (P < 0.05) but was positively correlated (r = 0.369) with the salivary TGF-β1 concentration (P < 0.05). Interestingly, MMP-9 was negatively correlated with TGF-β1 in the ibuprofen treatment group (r2 = -0.351). CONCLUSION Ibuprofen can inhibit the inflammatory process and delay healing in the extraction socket. After discontinuation of medication, no differences were observed in the healing effects between the paracetamol and ibuprofen groups. TRIAL REGISTRATION The clinical trial was retrospectively registered at the Australian New Zealand Clinical Trial Registry (ANZCTR) NHMRC Clinical Trials Centre, Camperdown, Australia (Registry URL: https://www.anzctr.org.au ) (Registration number: ACTRN12624000595516 Date: 9/5/2024).

Abstract
Background Complex wounds represent a challenge to global health, incurring significant healthcare costs and compromising patients' quality of life. Recently, research has investigated the potential of adipose tissue-derived stem cells (ASC) for therapeutic stem cells' immunomodulatory properties. This study aimed to evaluate the effect of sequential applications of ASC in an experimental model of a complex wound. Methods Thirty male Wistar rats were subjected to a complex wound model of enterocutaneous fistula. After 4 weeks, the rats were divided into 3 groups: control, 2 applications of culture medium, and 2 applications of 1 × 106 allogeneic ASC. The animals were euthanized and analyzed 4 weeks after the first application regarding the macroscopic reduction of the wound, histopathologic changes, and gene expression related to wound healing (Cd68, Il1rap, Il10, Mmp3, Mmp9, and Tnf). Results Animals treated with ASC showed a reduction in wound diameter of 68% compared with the control group (P = 0.002) and a reduction of 65% compared with the culture medium group (P = 0.011). The ASC group also showed a more than 100% increase in blood vessel count compared with the control group (P = 0.02). Gene expression analysis showed a decrease in the Mmp9 levels in the ASC group compared with the control group. Conclusions This study demonstrated that the treatment with ASC improves the healing of enterocutaneous fistula wounds.

Abstract
We aimed to compare the effectiveness of thymoquinone (TQ), the most important bioactive component of black cumin, St. John wort (SJW) oil, a traditional medicinal plant used in burns, and silver sulfadiazine (AgSD), a well-known antiinflammatory agent used in modern medicine, in an experimental burn rat-model. Sixty-three Wistar-Albino rats were randomly divided into 9 groups (n = 7). TQ and SJW were administered topically and systemically but AgSD was applied topically. Epithelialization, inflammatory cell response, granulation tissue, vascularization, and fibrosis were evaluated. Malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS), vitamin E, 8-hydroxy-deoxyguanosine (8-OHdG), coenzyme Q10 (CoQ10) were analyzed in serum. Topical TQ accelerated the epithelialization, enabled granulation, vascularization, and fibrosis in wounds (P = .001). Topical and systemic TQ increased Vitamin E levels (P = .003) but reduced TOS and 8-OHdG levels (P = .001). Topical SJW reduced granulation and vascularization. Topical and systemic SJW decreased TOS, MDA, and 8-OHdG levels (P = .001) but increased TAS (P = .001) and Vitamin E levels (P = .003). Topical AgSD reduced TOS, 8-OHdG, and MDA levels (P = .001). Topical and systemic TQ demonstrated significant advantages in accelerating the wound healing process while also enhancing antioxidant defenses and reducing oxidative damage. SJW oil, particularly in topical application, improved epithelialization, and antioxidant status but showed less efficacy in systemic use. AgSD, while effective in reducing oxidative stress, was less successful in promoting wound healing and appeared to delay granulation and fibrosis. Thymoquinone offers superior protective and healing benefits, SJW is effective locally but less so systemically, and AgSD should be used cautiously, potentially combined with antioxidants to mitigate its negative impact on wound healing.

Abstract
Wound healing is a complicated biological process that is important for restoring tissue integrity and function after injury. Infection, usually due to bacterial colonization, significantly complicates this process by hindering the course of healing and enhancing the chances of systemic complications. Recent advances in wearable biosensors have transformed wound care by making real-time monitoring of biomarkers such as pH, temperature, moisture, and infection-related metabolites like trimethylamine and uric acid. This review focuses on recent advances in biosensor technologies designed for wound management. Novel sensor architectures, such as flexible and stretchable electronics, colorimetric patches, and electrochemical platforms, enable the non-invasive detection of changes associated with wounds with high specificity and sensitivity. These are increasingly combined with AI and analytics based on smartphones that can enable timely and personalized interventions. Examples are the PETAL patch sensor that applies multiple sensing mechanisms for wide-ranging views on wound status and closed-loop systems that connect biosensors to therapeutic devices to automate infection control. Additionally, self-powered biosensors that tap into body heat or energy from the biofluids themselves avoid any external batteries and are thus more effective in field use or with limited resources. Internet of Things connectivity allows further support for remote sharing and monitoring of data, thus supporting telemedicine applications. Although wearable biosensors have developed relatively rapidly and their prospects continue to expand, regular clinical application is stalled by significant challenges such as regulatory, cost, patient compliance, and technical problems related to sensor accuracy, biofouling, and power, among others, that need to be addressed by innovative solutions. The goal of this review is to synthesize current trends, challenges, and future directions in wound healing and infection monitoring, with emphasis on the potential for wearable biosensors to improve patient outcomes and reduce healthcare burdens. These innovations are leading the way toward next-generation wound care by bridging advanced materials science, biotechnology, and digital health.

Abstract
Inflammatory reaction and neovascularization are crucial physiological processes that occur during postoperative wound healing. However, excessive inflammatory response and uncontrolled angiogenesis lead to scar formation, which severely limits the success rate of glaucoma filtration surgery. Peptide hydrogels were well-established to possess good biocompatibility, inherent biodegradability, extracellular matrix analog property, and high drug loading efficiency. Herein, we examined the potential of Arg-Gly-Asp (RGD) peptide hydrogel to inhibit inflammation and angiogenesis in vitro experiments. RGD peptide hydrogel exhibited significant inhibitory effects on the inflammatory response by ELISA and western blot and considerable prohibitive effects on neovascularization via inhibiting the proliferation and migration of vascular endothelial cells. In this study, we found a novel biomaterial, RGD peptide hydrogel, which has a certain anti-cell proliferation and anti-scarring effect in vitro experiments.

JOURNAL OF ETHNOPHARMACOLOGY 2025; 337:118983. [PMID: 39490430 DOI: 10.1016/j.jep.2024.118983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2024] [Revised: 10/17/2024] [Accepted: 10/21/2024] [Indexed: 11/05/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scientific publications documented the use of plants from Genus Malva to treat inflammatory diseases and skin disorders by our ancestors. Malva parviflora L. has reported benefits for wound healing in traditional medicine; however, there is a lack of experimental study to validate these claims. AIM We initiated this study to explore the metabolites and verify the wound healing properties of M. parviflora using in vivo and in vitro models. MATERIALS AND METHODS Liquid chromatography electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) was used to identify the ethanolic extract different metabolites. Additionally, total phenolic content was determined using Folin-Ciocalteu reagent. To verify the extract wound healing potential, an in vivo rat wound excision model was employed. Round wounds (5 mm in diameter) were created by a sterile biopsy punch needle. The wounds were treated with plant extracts (2.5% and 5%) as well as a commercially available wound healing product (Mebo®) for 10 days. The results were assessed as follows: 1) Measuring the reduction% in wound area compared to the original wound size. 2) Evaluation of the levels of wound healing biomarkers, namely collagen type I (Col-1), alpha smooth muscle actin (α-SMA), extracellular signal-regulated kinases-1 (ERK1), and matrix metalloproteinase-9 (MMP9) levels. 3) Performing histopathological examination of the wound tissue. The antioxidant properties of the M. parviflora leaves ethanolic extract were investigated using various assays: total antioxidant capacity (TAC), iron reducing power (IRP), 1,1-Diphenyl-2-picryl-hydrazyl (DPPH), and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals scavenging assays. Furthermore, the anti-inflammatory activity was confirmed by calculating the inhibition percentages of protein denaturation and the activity of the proteinase enzyme. RESULTS Liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis revealed the presence of various secondary metabolites in M. parviflora ethanolic extract, including phenolic acids (cinnamic and ferulic acids), flavonoids (quercetin and "iso"rhamnetin monoglucuronides), fatty acids (hydroxy-octadecatrienoic and oxo-octadecatrienoic acids), in addition to chlorophyll derivatives and carotenoids (pheophorbide-a and lutein, respectively). Malva extracts significantly reduced wound size compared to untreated control group. The extracts also promoted wound healing by upregulating collagen I, α-SMA, and ERK1 levels, while downregulating MMP9 expression. Notably, the effect of 2.5% and 5% extracts was similar or exceeds those of Mebo®, supported by histopathological results. Finally, M. parviflora ethanolic extract exhibited antioxidant and anti-inflammatory potentials comparable to the used standards. CONCLUSION Our study provides evidence-based support for the wound healing properties of M. parviflora L. leaves ethanolic extract. This is further strengthened by the fact that many of the identified metabolites possess wound healing, antioxidant, and/or anti-inflammatory activities.

Abstract
Field-effect transistor (FET) biosensors have significantly attracted interest across various disciplines because of their high sensitivity, time-saving, and label-free characteristics. However, it remains a grand challenge to interface the FET biosensor with complex liquid media. Unlike standard liquid electrolytes containing purified protein content, directly exposing FET biosensors to complex biological fluids introduces significant sensing noise, which is caused by the abundance of nonspecific proteins, viruses, and bacteria that adsorb to the biosensor surfaces. In this work, we leverage the hydrogel encapsulation on an MXene-graphene-based FET, which selectively allows the permeation of viruses (e.g., SARS-CoV-2) and bacteria (e.g., E. coli), leading to the high-specificity detection of those biomarkers. The results demonstrated that hydrogel encapsulation could successfully detect the SARS-CoV-2 biomarker at 1 fg/mL while preventing the diffusion of E. coli biomarkers, and the obtained signal output amplitude is twice that of sensors without hydrogel encapsulation, demonstrating significant advantages over conventional bare sensors.

Abstract
BACKGROUND In daily surgical practice, the dentist deals with various types of oral surgery. At the first visit, the patient fills out a questionnaire about their state of health. If the questionnaire does not reveal any particular hematological problems, no special tests are usually required to determine the platelet count. The aim of this prospective study was to evaluate the healing process of patients and its correlation with platelet levels before surgery. METHODS A total of 50 patients were included in whom blood chemistry tests were performed with special attention to the platelet count and before their mandibular eights were extracted .The type of healing (EHI) and pain on the second day (VAS) were assessed using methods validated in the literature. RESULTS After the EHI and VAS scores were noted in the medical records, envelopes containing the platelet scores of the previously requested blood samples, which were not read at the time of observation, were opened. An increase in EHI scores and a decrease in VAS scores was observed that were statistically significantly correlated with increasing platelet scores. CONCLUSIONS These results suggest that the dentist should request chemistry tests on preoperative blood, especially if the patient is to undergo a particularly demanding oral surgical procedure, such as implants, guided bone regeneration or complex extractions.

Abstract
Background One of the key obstacles to the healing of diabetic wound is the persistence of active inflammation. We previously demonstrated the potential of cell-free fat extract (CEFFE) to promote the healing of diabetic wounds, and annexin A5 (A5) is a crucial anti-inflammatory protein within CEFFE. This study aimed to evaluate the therapeutic potential of A5 in diabetic wounds. Methods A5 was loaded into GelMA hydrogels and applied to skin wounds of diabetic mice in vivo. The diabetic wounds with the treatment of GelMA-A5 were observed for 14 days and evaluated by histological analysis. Accessment of inflammation regulation were conducted through anti-CD68 staining, anti-CD86 and anti-CD206 staining, and qRT-PCR of wound tissue. In presence of A5, macrophages stimulated by lipopolysaccharide (LPS) in vitro, and detected through qRT-PCR, flow cytometry, and immunocytofluorescence staining. Besides, epithelial cells were co-cultured with A5 for epithelialization regulation by CCK-8 assay and cell migration assay. Results A5 could promote diabetic wound healing and regulate inflammations by promoting the transition of macrophages from M1 to M2 phenotype. In vitro experiments demonstrated that A5 exerted a significant effect on reducing pro-inflammatory factors and inhibiting the polarization of macrophages from M0 toward M1 phenotype. A5 significantly promoted the migration of epithelial cells. Conclusion Annexin A5 has a significant impact on the regulation of macrophage inflammation and promotion of epithelialization.

Abstract
BACKGROUND Following lower limb amputation, timely prosthetic fitting enhances mobility and quality of life. However, inconsistent definitions of surgical site healing complicate prosthesis readiness assessment and highlight the need for objective wound management measures. OBJECTIVE This review aimed to compile definitions of healing and non-healing provided in the literature investigating biomarkers of healing of the tissues and structures found in the residual limbs of adults with amputation. METHODOLOGY A scoping review was conducted following JBI and PRISMA-ScR guidance. Searches using "biomarkers," "wound healing," and "amputation" were performed on May 6, 2023, on Web of Science, Ovid MEDLINE, Ovid Embase, Scopus, Cochrane, PubMed, and CINAHL databases. Inclusion criteria were: 1) References to biomarkers and healing; 2) Residuum tissue healing; 3) Clear methodology with ethical approval; 4) Published from 2017 onwards. Articles were assessed for quality (QualSyst tool) and evidence level (JBI system). FINDINGS Of 3,306 articles screened, 219 met the inclusion criteria and are reviewed in this article, with 77% rated strong quality. 43% of all included sources did not define healing, while the remainder used specific criteria including epithelialization (14%), wound size reduction (28%), gradings scales (3%), scarring (1%), absence of wound complications (2%), hydroxyproline levels (0.5%), no amputation (0.5%), or neovascularization (0.5%). 84% of included sources did not provide definitions of non-healing. Studies defining non-healing used criteria like wound complications (4%), the need for operative interventions (4%), or lack of wound size reduction (1%). For 10% of included sources, healing and non-healing definitions were considered not applicable given the research content. Total percentages exceed 100% for both healing and non-healing definitions because some sources used two definition classifications, such as epithelialization and wound size reduction. The findings indicate a lack of standardized definitions irrespective of study type. CONCLUSION This review reveals significant gaps in current definitions of healing and non-healing, often based on superficial assessments that overlook deeper tissue healing and mechanical properties essential for prosthesis use. It emphasizes the need for comprehensive definitions incorporating biomarkers and psychosocial factors to improve wound management and post-amputation recovery.

Abstract
For several decades, there has been growing interest in the influence of low-frequency magnetic fields (LFMFs) and red LED light on the healing process. Keratinocytes are cells that play a significant role in the process of wound healing and tissue regeneration. A human keratinocyte cell line (HaCaT) was exposed to an LFMF with low induction (180-195 Hz; 60 µT, magnetostimulation), red LED light (630 nm; 300 mW, LED therapy), and their combined action (magneto-LED therapy) in in vitro culture conditions. On day 4 and 8 of the experiment, the following parameters were determined: adhesion/proliferation, adenylate kinase (AK), nitric oxide (NO), cytokines (IL-1β, IL-6, IL-8, IL-10, IL-12p70, TNF-α), metalloproteinases (MMP-2, MMP-9), and collagen IV. It was shown that magnetostimulation caused an increase in keratinocyte adhesion/proliferation and IL-8 secretion and a decrease in IL-12 secretion. The LED therapy resulted in a transient increase in the secretion of NO and cytokines IL-1, IL-12, and IL-6 in keratinocytes. The use of magneto-LED therapy resulted in an increase in keratinocyte adhesion/proliferation, the secretion of cytokines IL-6 and IL-8, and NO with a simultaneous decrease in MMP-9 secretion. The results of our studies showed that the action of an LFMF with low-induction and LED light on keratinocytes can modulate the biological activity of keratinocytes towards improving the skin healing process.

Abstract
Chronic wounds can develop as a result of prolonged inflammation during the healing process, which can happen due to bacterial infection. Therefore, preventing infection and controlling inflammation can accelerate wound healing. Antimicrobial peptides have different protective properties in addition to antimicrobial activity. Some of these activities include the stimulation of cytokine or chemokine synthesis, the facilitation of chemotaxis and cell proliferation, the acceleration of cell proliferation, the induction of anti-inflammatory responses, and the promotion of wound repair. This study aimed to assess the wound healing potential of a novel in silico-designed antimicrobial peptide. Then, its anti-inflammatory activity was investigated by measuring the level of tumor necrosis factor-α (TNF-α) and transforming growth factor beta (TGF-β) as indicators of the wound healing process. In addition, the influence of the peptide on cell migration was evaluated by a scratch test on human dermal fibroblasts (HDF) and HaCaT cells as a human epidermal keratinocyte cell line. The results showed that our new peptide could act well in inhibiting TNF-α over-secretion while increasing the expression of TGF-β as an anti-inflammatory factor. This peptide showed a significant potential to stimulate HDF and HaCaT cell migration and proliferation. Therefore, using this peptide as an anti-inflammatory component of wound dressings may be promising.

Abstract
Pseudomonas aeruginosa is a highly drug-resistant pathogen known to impair wound healing and provoke inflammatory responses, potentially leading to immune dysregulation. This study aimed to systematically investigate the immune response mechanisms mediated by cytokines following P. aeruginosa infection through the development of a standardized wound model. Kunming mice were selected as experimental subjects and given 8 mm diameter lesions on their backs and inoculated with standard strains PAO1 and PA14. The key parameters assessed included changes in body weight, wound redness and swelling, bacterial dynamics, protein content in wound tissues, immune responses, and pathological alterations. The results demonstrated that pathogen invasion significantly inhibited wound healing, with healing rates in the infected groups (87.5 ± 6.3% and 77.1 ± 3.6%) being notably lower than those in the uninfected control group. P. aeruginosa persisted in the wounds for up to 12 days, with bacterial loads decreasing from 8 log to 2 log. Additionally, there was a marked reduction in the protein content of the wound tissue and an increase in the expression levels of inflammatory factors such as IL-1β and TNF-α. The thickness of granulation tissue and the number of neovessels were significantly lower compared to the uninfected control group. This study establishes a standardized paradigm for creating a mouse model of P. aeruginosa infection in wounds, emphasizing the importance of appropriate mouse strains, uniform wound preparation methods, and moderate inoculation doses for reliable and accurate experimental results. These elements will facilitate the assessment of changes across six key indicators post-infection, providing a foundational data set and technical support for future mechanistic investigations of P. aeruginosa infection and the development of targeted antimicrobial strategies.

Abstract
Bacterial cellulose (BC) regularly uses chemical or physical modifications to produce antimicrobial wound dressings. However, there is a risk of loss of functional components during application. Moreover, a significant hurdle lies in successfully integrating durable and highly effective bactericidal entities with BC. Herein, we successfully synthesized a photodynamic antibacterial cellulose through direct in situ microbial fermentation, incorporating the photosensitizer protoporphyrin IX-modified glucosamine (PPIX-GlcN) into cellulose to form PIXX-BC biopolymers. Excitingly, the PPIX-BC membrane exhibited robust and uniform red fluorescence, which is crucial for monitoring the bacterial fermentation process. Our results demonstrated that the biocompatibility PPIX-BC membrane possessed potent light-triggered photodynamic bactericidal activity, effectively suppressing the growth of E. coli and S. aureus while also promoting skin wounds repair. Consequently, this research validated the possibility of leveraging microorganisms to bio-functionalize BC, conferring it with photocatalytic antibacterial properties. Furthermore, successfully modification of the microorganisms' glucose carbon source offers valuable insights into biosynthesis of other living materials through microbial metabolism.

Abstract
The global socioeconomic challenge generated by wounds requires an understanding of healing and non-healing pathways in patients. Also, the interactions occurring between the wound dressing biomaterials with cells relevant to the healing process have not been sufficiently investigated, thus neglecting the role that wound dressing composition can play in healing. Through the study of six cases of acute surgical wounds, the present work analyses the early (24 h post-surgery) interactions of biochemical and cellular components with (i) Atrauman, a device made of knitted woven synthetic polymeric fibre when used as a primary dressing, and (ii) Melolin, a hydrocolloid engineered as two layers of synthetic and cellulose non-woven fibres when used as a secondary dressing. A pathway towards healing could be observed in those cases where endoglin-expressing cells and M2 macrophages were retained by Atrauman fibres at the interface with the wound bed. On the contrary, cases where the secondary dressing Melolin absorbed these cell phenotypes in its mesh resulted in a slower or deteriorating healing process. The data obtained indicate that a subtraction of progenitor cells by Melolin may impair the healing process and that the analysis of the retrieved wound dressings for biomarkers expressed by cells relevant to wound healing may become an additional tool to determine the patient's prognosis.

Abstract
Immunohistochemical analysis of platelet-derived growth factor receptor-α (PDGFR-α) was performed on human skin wounds obtained from forensic autopsy cases. Thirty human skin wounds were collected at different post-infliction intervals as follows: Group I, 4 h to 3 days (n = 16); Group II, 4 to 7 days (n = 7); Group III, 9 to 10 days (n = 3); and Group IV, 14 to 20 days (n = 4). Immunopositive reactions for PDGFR-α were not observed in the uninjured human skin specimens. In a semi-quantitative morphometrical analysis, the number of PDGFR-α-positive cells was observed increased in Group II, with the average number of PDGFR-α-positive cells being the highest in Group II. Additionally, in Group II, all specimens showed PDGFR-α-positive cells, with an average number of > 200 cells in five fields of view, suggesting a wound age of 4 to 7 days. Taken together, the immunohistochemical detection of PDGFR-α in human skin wounds can be a useful tool for wound age determination.

Abstract
The development of diabetic foot ulcers is a common and severe complication of diabetes that can significantly affect quality of life. The physiological healing cascade does not progress tissue repair in diabetic foot ulcerations in a timely manner. Serum markers from foot ulcers have been used to characterize the healing process of the diabetic foot using various collection techniques. This study aimed to compare the use of cervical brushes and the Levine technique to collect wound fluid from foot ulcers of people with diabetes in order to determine the presence of cytokines. The collected material was used for gene expression analysis of macrophage/monocyte-associated cytokines IL1-β, IL-6, TNF-α, regulatory cytokine IL-10 and growth factor TGFβ, via quantitative polymerase chain reaction (qPCR). Both collection methods produced sufficient amounts of RNA, but significantly more RNA was collected using a cervical brush (brush 224.82 ng/μL vs. Levine 80.90 ng/μL p = 0.0001). Significantly higher levels of expression of the following cytokine genes were detected in samples collected using a cervical brush: IL1-β (p = 0.0001), IL-6 (p = 0.0106), IL-10 (p = 0.0277) and TGFβ (p = 0.0002). Understanding why some wounds are difficult to heal is important for developing more effective treatments, and biomarkers may be useful for predicting the healing trajectory. These results demonstrate that it is possible to collect material from the wound bed for RT-qPCR analysis, and the cervical brush proved to be a simple and rapid method for monitoring cytokine gene expression.

Abstract
Wound healing is a complex biological process involving a coordinated sequence of events aimed at restoring tissue integrity and function. Recent advancements in wound care have introduced novel therapies, with topical insulin application emerging as a promising strategy for promoting tissue healing. This study, involving 60 female cats (n = 60) undergoing elective spaying, aimed to evaluate the effects of topical fast-acting insulin on the healing process of surgical wounds. Each surgical suture was divided into two regions: the control zone (Zcr) without insulin application and the study zone (Zst), where insulin was applied topically for 10 min every 24 h over eight consecutive days. Assessment of suture healing was conducted using an adapted scale at two time points post-surgery: T1 (day 2) and T2 (day 8). Statistically significant differences were registered in the final healing scale scores between Zcr and Zst (p < 0.022), as well as for the parameter of regional fluid (p-value = 0.017). Additionally, at T2, all Zst regions exhibited wound closure, whereas Zcr did not, although not in a statistically significant manner. The observed discrepancy at T2 between the Zcr and Zst regions may suggest a potential benefit of utilizing insulin. No side effects resulting from the insulin topical application performed by the tutors were recorded in the Zst suture group. This study represents the first exploration of the benefits of topical insulin application for surgical wound healing in cats.

Abstract
The pathogenesis of chronic wounds (CW) involves a multifaceted interplay of biochemical, immunological, hematological, and microbiological interactions. Biofilm development is a significant virulence trait which enhances microbial survival and pathogenicity and has various implications on the development and management of CW. Biofilms induce a prolonged suboptimal inflammation in the wound microenvironment, associated with delayed healing. The composition of wound fluid (WF) adds more complexity to the subject, with proven pro-inflammatory properties and an intricate crosstalk among cytokines, chemokines, microRNAs, proteases, growth factors, and ECM components. One approach to achieve information on the mechanisms of disease progression and therapeutic response is the use of multiple high-throughput 'OMIC' modalities (genomic, proteomic, lipidomic, metabolomic assays), facilitating the discovery of potential biomarkers for wound healing, which may represent a breakthrough in this field and a major help in addressing delayed wound healing. In this review article, we aim to summarize the current progress achieved in host-microbiome crosstalk in the spectrum of CW healing and highlight future innovative strategies to boost the host immune response against infections, focusing on the interaction between pathogens and their hosts (for instance, by harnessing microorganisms like probiotics), which may serve as the prospective advancement of vaccines and treatments against infections.

Abstract
Chronic wounds remain a significant clinical challenge both for those affected and for healthcare systems. The treatment is often comprised and complex. All patients should receive wound care that is integrated into a holistic approach involving local management that addresses the underlying etiology and provides for gold standard therapy to support healing, avoid complications and be more cost effective. There have been significant advances in medicine over the last few decades. The development of new technologies and therapeutics for the local treatment of wounds is also constantly increasing. To help standardize clinical practice with regard to the multitude of wound products, the M.O.I.S.T. concept was developed by a multidisciplinary expert group. The M stands for moisture balance, O for oxygen balance, I for infection control, S for supporting strategies, and T for tissue management. Since the M.O.I.S.T. concept, which originated in the German-speaking countries, is now intended to provide healthcare professionals with an adapted instrument to be used in clinical practice, and a recent update to the concept has been undertaken by a group of interdisciplinary experts to align it with international standards. The M.O.I.S.T. concept can now be used internationally both as an educational tool and for the practical implementation of modern local treatment concepts for patients with chronic wounds and can also be used in routine clinical practice.

Non-healing wounds represent a significant burden for healthcare systems and society, giving rise to severe economic and human issues. Currently, the use of dressings and visual assessment represent the primary and standard care for wounds. Conventional dressings, like cotton gauze, provide only passive physical protection. Besides, they end up paradoxically hampering the wound-healing process by producing tissue damage and pain when removed during routine check-ups. In response to these limitations, researchers, engineers, and technologists are developing innovative dressings that incorporate advanced diagnostic and therapeutic functionalities, coined as "smart dressings". Now, the maturation of smart dressing is bringing them closer to real-life applications, leading to an exciting new generation of these devices. The next generation of smart dressings is capable of monitoring in real-time multiple biomarkers while including pro-healing capabilities in a single platform. Such multiplexed and theranostic smart dressings are expected to offer a timely biomarker-directed diagnosis of non-healing wounds while enabling rapid, automated, and personalized treatments of infection and chronicity. Herein, we provide an insightful overview of these advantageous devices, delving into the diverse spectrum of possible engineering strategies. This encompasses the use of electrochemical and optical platforms with diverse multiplexing architectures, such as multi-zone sensing arrays and multi-layered devices. Open or closed-loop theranostic mechanisms using various stimuli-responsive materials that could be internally or externally controlled are also included. Finally, a critical discussion on the main challenges and future directions of smart dressings is also offered.

Abstract
Burn wound healing is a complex process orchestrated through successive biochemical events that span from weeks to months depending on the depth of the wound. Here, we report an untargeted metabolomics discovery approach to capture metabolic changes during the healing of deep partial-thickness (DPT) and full-thickness (FT) burn wounds in a porcine burn wound model. The metabolic changes during healing could be described with six and seven distinct metabolic trajectories for DPT and FT wounds, respectively. Arginine and histidine metabolism were the most affected metabolic pathways during healing, irrespective of burn depth. Metabolic proxies for oxidative stress were different in the wound types, reaching maximum levels at day 14 in DPT burns but at day 7 in FT burns. We examined how acellular fish skin graft (AFSG) influences the wound metabolome compared to other standard-or-care burn wound treatments. We identified changes in metabolites within the methionine salvage pathway, specifically in DPT burn wounds that is novel to the understanding of the wound healing process. Furthermore, we found that AFSGs boost glutamate and adenosine in wounds that is of relevance given the importance of purinergic signaling in regulating oxidative stress and wound healing. Collectively, these results serve to define biomarkers of burn wound healing. These results conclusively contribute to the understanding of the multifactorial mechanism of the action of AFSG that has traditionally been attributed to its structural properties and omega-3 fatty acid content.

Int Endod J 2023; 56:1432-1445. [PMID: 37712904 DOI: 10.1111/iej.13976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUND The mechanism of action of root resorption in a permanent tooth can be classified as infection-related (e.g., microbial infection) or non-infection-related (e.g., sterile damage). Infection induced root resorption occurs due to bacterial invasion. Non-infection-related root resorption stimulates the immune system through a different mechanism. OBJECTIVES The aim of this narrative review is to describe the pathophysiologic process of non-infection-related inflammatory processes involved in root resorption of permanent teeth. METHODS A literature search on root resorption was conducted using Scopus (PubMed and Medline) and Google Scholar databases to highlight the pathophysiology of bone and root resorption in non-infection-related situations. The search included key words covering the relevant category. It included in vitro and in vivo studies, systematic reviews, case series, reviews, and textbooks in English. Conference proceedings, lectures and letters to the editor were excluded. RESULTS Three types of root resorption are related to the non-infection mechanism of action, which includes surface resorption due to either trauma or excessive orthodontic forces, external replacement resorption and external cervical resorption. The triggers are usually damage associated molecular patterns and hypoxia conditions. During this phase macrophages and clastic cells act to eliminate the damaged tissue and bone, eventually enabling root resorption and bone repair as part of wound healing. DISCUSSION The resorption of the root occurs during the inflammatory phase of wound healing. In this phase, damaged tissues are recognized by macrophages and neutrophiles that secrete interlaukines such as TNF-α, IL-1, IL-6, IL-8. Together with the hypoxia condition that accelarates the secretion of growth factors, the repair of the damaged perioduntiom, including damaged bone, is initiated. If the precementum and cementoblast are injured, root resorption can occur. CONCLUSIONS Wound healing exhibits different patterns of action that involves immune stimulation in a bio-physiological activity, that occurs in the proper sequence, with overlapping phases. Two pathologic conditions, DAMPs and hypoxia, can activate the immune cells including clastic cells, eliminating damaged tissue and bone. Under certain conditions, root resorption occurs as a side effect.

Abstract
INTRODUCTION One of the most common problems of diabetes are diabetic foot ulcers (DFUs). According to National Institute for Health, initial management of DFUs can decrease the complication of limb amputations and can improve the patient's quality of life. DFU treatment can be optimized with the help of multidisciplinary approach. Based on many studies, control of glucose levels in blood, antioxidant activity, reduction in cytokine levels, re-epithelialization, collagen formation, migration of fibroblasts are major phases involved in managing DFU. Dehydrozingerone (DHZ), has been known for its anti-inflammatory, antioxidant and wound healing properties. METHODOLOGY Three months high-fat diet and low dose of streptozotocin-induced type-II diabetic foot ulcer model was used to evaluate the effectiveness of dehydrozingerone. DHZ was given orally to rats for 15 days post wounding. TNF-α, IL-1β and antioxidant parameters like lipid peroxidation, glutathione reductase were estimated. Immunoblotting was done to investigate the effect of DHZ on the expression of ERK, JNK, HSP-27, P38, SIRT-1, NFκB, SMA, VEGF and MMP-9 in skin tissue. Histopathology was performed for analyzing DHZ effect on migration of fibroblasts, formation of epithelium, granulation tissue formation, angiogenesis and collagen formation. RESULTS DHZ decreased the levels of malondialdehyde, TNF-α, IL-1β and increased glutathione levels in wound tissue. Western blotting results suggested that DHZ activated ERK1/2/JNK/p38 signaling, increased expression of HSP-27, SIRT-1, VEGF, SMA thus facilitating the migration and proliferation of fibroblasts, angiogenesis and decreased inflammation. Masson Trichrome & histopathology showed an increase in collagen, epithelial and granulation tissue formation. CONCLUSION DHZ significantly accelerates the healing of diabetic foot ulcers in high fat diet fed plus low dose streptozotocin induced type-II diabetic Wistar rats.

Abstract
Epithelial keratinocyte proliferation is an essential element of wound repair, and chronic wound conditions, such as diabetic foot, are characterized by aberrant re-epithelialization. In this study, we examined the functional role of retinoic acid inducible-gene I (RIG-I), a key regulator of epidermal keratinocyte proliferation, in promoting TIMP-1 expression. We found that RIG-I is overexpressed in keratinocytes of skin injury and underexpressed in skin wound sites of diabetic foot and streptozotocin-induced diabetic mice. Moreover, mice lacking RIG-I developed an aggravated phenotype when subjected to skin injury. Mechanistically, RIG-I promoted keratinocyte proliferation and wound repair by inducing TIMP-1 via the NF-κB signaling pathway. Indeed, recombinant TIMP-1 directly accelerated HaCaT cell proliferation in vitro and promoted wound healing in Ddx58-/- and diabetic mice in vivo. In summary, we demonstrated that RIG-I is a crucial factor that mediates epidermal keratinocyte proliferation and may be a potential biomarker for skin injury severity, thus making it an attractive locally therapeutic target for the treatment of chronic wounds such as diabetic foot.

Abstract
Wound healing is a sophisticated process consisting of serial phases with overlaps, including hemostasis, inflammation, proliferation, and remodeling. The inflammation response is an early response that plays a crucial role in eliminating microbes and clearing damaged cell debris. However, in some pathological circumstances, such as diabetes mellitus, ischemia, trauma, deep burn, etc., abnormal inflammation can cause impaired wound healing. Adipose-derived stem cells (ADSCs) belong to the mesenchymal stem cell (MSC) family and exhibit prospective applications in tissue regeneration and dermatological repairs. ADSC-secreted extracellular vesicles (ADSC-EVs) mimic the functions of ADSCs without the concerns of cell survival, immune response, or ethical issues. Studies have revealed that ADSC-EVs can inhibit abnormal inflammation responses and accelerate wound healing through various mechanisms. Moreover, some studies explored modifications in the cargo components of ADSC-EVs to enhance their therapeutic efficacy. Given the increasing studies focusing on the potential of ADSC-EVs in wound healing, how they interfere with different phases of this process has been investigated in pieces. In this review, we summarized all up-to-date evidence to map a clearer picture of the underlying mechanisms of ADSC-EVs in inflammation response. The applications of ADSC-EVs aiming at inflammation in the healing process were also reviewed to provide therapeutic strategies for future investigators.

Abstract
Uncontrolled inflammation is linked to poor outcomes in sepsis and wound healing, both of which proceed through distinct inflammatory and resolution phases. Eicosanoids are a class of bioactive lipids that recruit neutrophils and other innate immune cells. The interaction of ceramide 1-phosphate (C1P) with the eicosanoid biosynthetic enzyme cytosolic phospholipase A2 (cPLA2) reduces the production of a subtype of eicosanoids called oxoeicosanoids. We investigated the effect of shifting the balance in eicosanoid biosynthesis on neutrophil polarization and function. Knockin mice expressing a cPLA2 mutant lacking the C1P binding site (cPLA2αKI/KI mice) showed enhanced and sustained neutrophil infiltration into wounds and the peritoneum during the inflammatory phase of wound healing and sepsis, respectively. The mice exhibited improved wound healing and reduced susceptibility to sepsis, which was associated with an increase in anti-inflammatory N2-type neutrophils demonstrating proresolution behaviors and a decrease in proinflammatory N1-type neutrophils. The N2 polarization of cPLA2αKI/KI neutrophils resulted from increased oxoeicosanoid biosynthesis and autocrine signaling through the oxoeicosanoid receptor OXER1 and partially depended on OXER1-dependent inhibition of the pentose phosphate pathway (PPP). Thus, C1P binding to cPLA2α suppresses neutrophil N2 polarization, thereby impairing wound healing and the response to sepsis.

Abstract
The suboptimal or protracted regeneration of injured connective tissues often results in significant dysfunction, pain, and functional disability. Despite the prevalence of the condition, few studies have been conducted which focused on biomarkers or key molecules involved in processes governing healing outcomes. To gain insight into injured connective tissue repair, and using the Achilles tendon as a model system, we utilized quantitative proteomic and weighted co-expression network analysis of tissues acquired from Achilles tendon rupture (ATR) patients with different outcomes at 1-year postoperatively. Two modules were detected to be associated with prognosis. The initial analysis identified inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4) as a biomarker or hub protein positively associated with better healing outcomes. Additional analysis identified the beneficial role of ITIH4 in inflammation, cell viability, apoptosis, proliferation, wound healing, and for the synthesis of type I collagen in cultured fibroblasts. Functionally, the effects of ITIH4 were found to be mediated by peroxisome proliferator-activated receptor gamma (PPARγ) signaling pathways. Taken together, these findings suggest that ITIH4 plays an important role in processes of connective tissue repair and advocate for the potential of ITIH4 as a therapeutic target for injured connective tissue repair.

Abstract
Bacterial overgrowth in injured wounds causes wound infection and excessive inflammation, leading to delayed wound healing. Successful treatment of delayed infected wound healing demands dressings, which can inhibit bacterial growth and inflammation and simultaneously induce vascularization, collagen deposition, and re-epithelialization of wounds. In this study, bacterial cellulose (BC) deposited with Cu2+-loaded phase-transited lysozyme (PTL) nanofilm (BC/PTL/Cu) was prepared for healing infected wounds. The results confirm that PTL were successfully self-assembled on BC matrix, and Cu2+ were loaded into PTL through electrostatic coordination. The tensile strength and the elongation at break of the membranes were not significantly changed after modification with PTL and Cu2+. Compared with BC, the surface roughness of BC/PTL/Cu significantly increased while the hydrophilicity decreased. Moreover, BC/PTL/Cu displayed slower release rate of Cu2+ compared with BC directly loaded with Cu2+. BC/PTL/Cu exhibited good antibacterial activity against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Pseudomonas aeruginosa. By controlling copper concentration, BC/PTL/Cu were not cytotoxic to mouse fibroblast cell line L929. In vivo, BC/PTL/Cu accelerated wound healing and promoted re-epithelialization, collagen deposition, and angiogenesis while inhibiting inflammation of the infected full-thickness skin wounds of rats. Collectively, these results demonstrate that BC/PTL/Cu composites are promising dressings for healing infected wounds.

Int Wound J 2023; 20:1098-1111. [PMID: 36181308 PMCID: PMC10031222 DOI: 10.1111/iwj.13966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 08/31/2022] [Accepted: 09/11/2022] [Indexed: 11/30/2022] Open
Abstract
The purpose of this study was: (1) to characterise the association of wound area, wound exudate C-reactive protein (CRP), broad-spectrum matrix metalloprotease protein (MMPs), and symptoms of fatigue and pain in individuals with chronic venous leg ulcers (CVLUs) over time and (2) to identify factors associated with the wound healing trajectory in CVLUs. Seventy four participants with CVLU who received weekly sharp debridement were recruited from a wound care clinic during the 8-week study period. To examine associations among wound CRP, MMPs, pain, fatigue, and wound healing trajectory over time, we calculated Bayes factors (BF) based on a linear mixed model. The mean age of participants was 71.8 (SD = 9.8) and the mean wound area was 2278 mm2 (SD = 7085 mm2 ) at baseline. Higher fatigue was strongly associated with higher MMPs (BF = 9, 95% HDI: [-.05, .43]), lower CRP (BF = 11, 95% HDI: [-.02, .002]), and large areas of wound (BF = 20, 95% HDI: [-.001, .01]). Higher CRP and MMPs activity in wound exudate and higher fatigue were associated with a larger wound area. To facilitate wound healing, clinicians need to utilise the multifactorial approach, which includes wound treatment and management of symptoms such as pain and fatigue, because of the molecular and psycho-behavioural factors involved in wound healing.

Abstract
Chronic nonhealing wounds are one of the major and rapidly growing clinical complications all over the world. Current therapies frequently require emergent surgical interventions, while abuse and misapplication of therapeutic drugs often lead to an increased morbidity and mortality rate. Here, we introduce a wearable bioelectronic system that wirelessly and continuously monitors the physiological conditions of the wound bed via a custom-developed multiplexed multimodal electrochemical biosensor array and performs noninvasive combination therapy through controlled anti-inflammatory antimicrobial treatment and electrically stimulated tissue regeneration. The wearable patch is fully biocompatible, mechanically flexible, stretchable, and can conformally adhere to the skin wound throughout the entire healing process. Real-time metabolic and inflammatory monitoring in a series of preclinical in vivo experiments showed high accuracy and electrochemical stability of the wearable patch for multiplexed spatial and temporal wound biomarker analysis. The combination therapy enabled substantially accelerated cutaneous chronic wound healing in a rodent model.

Abstract
Diabetes mellitus (DM) is an important cause of chronic wounds and non-traumatic amputation. The prevalence and number of cases of diabetic mellitus are increasing worldwide. Keratinocytes, the outermost layer of the epidermis, play an important role in wound healing. A high glucose environment may disrupt the physiologic functions of keratinocytes, resulting in prolonged inflammation, impaired proliferation, and the migration of keratinocytes and impaired angiogenesis. This review provides an overview of keratinocyte dysfunctions in a high glucose environment. Effective and safe therapeutic approaches for promoting diabetic wound healing can be developed if molecular mechanisms responsible for keratinocyte dysfunction in high glucose environments are elucidated.

Abstract
The delayed healing of diabetic wounds is directly affected by the disturbance of wound microenvironment, resulting from persistent inflammation, insufficient angiogenesis, and impaired cell functions. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) showed considerable therapeutic potential in diabetic wound healing. However, the low retention rate of MSC-EVs at wound sites hampers their efficacy. For skin wounds exposed to the outer environment, using a hydrogel with tissue adhesiveness under a moist wound condition is a promising strategy for wound healing. In this study, we modified methacryloyl-modified gelatin (GelMA) hydrogel with catechol motifs of dopamine to fabricate a GelMA-dopamine hydrogel. EVs isolated from MSCs were applied in the synthesized GelMA-dopamine hydrogel to prepare a GelMA-dopamine-EV hydrogel. The results demonstrated that the newly formed GelMA-dopamine hydrogel possessed improved properties of softness, adhesiveness, and absorptive capacity, as well as high biocompatibility in the working concentration (15% w/v). In addition, MSC-EVs were verified to promote cell migration and angiogenesis in vitro. In the skin wound model of diabetic rats, the GelMA-dopamine-EV hydrogel exerted prominent wound healing efficacy estimated by collagen deposition, skin appendage regeneration, and the expression of IL-6, CD31, and TGF-β. In conclusion, this combination of MSC-EVs and the modified hydrogel not only accelerates wound closure but also promotes skin structure normalization by rescuing the homeostasis of the healing microenvironment of diabetic wounds, which provides a potential approach for the treatment of diabetic wounds.

Abstract
Bone-substitute materials are essential in dental implantology. We prepared collagen (Col)/hydroxyapatite (Hap)/acidic gelatin (AG)/basic fibroblast growth factor (b-FGF) constructs with enhanced bone-forming capability. The Col/Hap apatite composites were prepared by immersing Col sponges alternately in calcium and phosphate ion solutions five times, for 20 and 60 min, respectively. Then, the sponges were heated to 56 °C for 48 h. Scanning electron microscopy/energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction analyses showed that the Col/Hap composites contained poorly crystalline Hap precipitates on the Col matrix. Col/Hap composite granules were infiltrated by AG, freeze-dried, and immersed in b-FGF solution. The wet quaternary constructs were implanted in rat cranial bone defects for 8 weeks, followed by soft X-ray measurements and histological analysis. Animal studies have shown that the constructs moderately increase bone formation in cranial bone defects. We found that an alternate immersion time of 20 min led to the greatest bone formation (p < 0.05). Constructs placed inside defects slightly extend the preexisting bone from the defect edges and lead to the formation of small island-like bones inside the defect, followed by disappearance of the constructs. The combined use of Col, Hap, AG, and b-FGF might bring about novel bone-forming biomaterials.

Abstract
Wound healing is a complex biological process involving various cells, mediators, and components of the extracellular matrix involved in the processes of coagulation, inflammation, angiogenesis, epithelialization, and fibroplasia. Wound healing is described by four interrelated phases: hemostasis, inflammation, proliferation and remodeling. Each of the phases has its role at the molecular and tissue levels, and if a defect occurs in the chain of one of the phases of the wound healing process, the healing process is disturbed and a chronic wound condition occurs. Various factors such as infections, arterial and venous circulatory disorders, type 2 diabetes and chronic inflammation contribute to this. Prolonged non-healing wounds represent an urgent problem of modern medicine. Oxidative stress plays a crucial role in the pathogenesis of chronic wounds. In this review the pathogenesis of chronic wounds and its involvement of reactive oxygen species (ROS), oxidative stress, the role of mitochondria in ROS generation as well as the prospects of mitochondrial-directed antioxidants in the treatment of chronic wounds are considered.

Abstract
Recent advancements in regenerative medicine have enhanced the development of biomaterials as multi-functional dressings, capable of accelerating wound healing and addressing the challenge of chronic wounds. Hydrogels obtained from decellularized tissues have a complex composition, comparable to the native extracellular environment, showing highly interesting characteristics for wound healing applications. In this study, a bovine pericardium decellularized extracellular matrix (dECM) hydrogel was characterized in terms of macromolecules content, and its immunomodulatory, angiogenic and wound healing potential has been evaluated. The polarization profile of human monocytes-derived macrophages seeded on dECM hydrogel was assessed by RT-qPCR. Angiogenic markers expression has been evaluated by Western blot and antibody array on cell lysates derived from endothelial cells cultured on dECM hydrogel, and a murine in vivo model of hindlimb ischemia was used to evaluate the angiogenic potential. Fibroblast migration was assessed by a transwell migration assay, and an in vivo murine wound healing model treated with dECM hydrogels was also used. The results showed a complex composition, of which the major component is collagen type I. The dECM hydrogel is biocompatible, able to drive M2 phenotype polarization, stimulate the expression of angiogenic markers in vitro, and prevent loss of functionality in hindlimb ischemia model. Furthermore, it drives fibroblast migration and shows ability to facilitate wound closure in vivo, demonstrating its great potential for regenerative applications.

Abstract
Chronic wounds are characterized by their inability to heal within an expected time frame and have emerged as an increasingly important clinical problem over the past several decades, owing to their increasing incidence and greater recognition of associated morbidity and socio-economic burden. Even up to a few years ago, the management of chronic wounds relied on standards of care that were outdated. However, the approach to these chronic conditions has improved, with better prevention, diagnosis and treatment. Such improvements are due to major advances in understanding of cellular and molecular aspects of basic science, in innovative and technological breakthroughs in treatment modalities from biomedical engineering, and in our ability to conduct well-controlled and reliable clinical research. The evidence-based approaches resulting from these advances have become the new standard of care. At the same time, these improvements are tempered by the recognition that persistent gaps exist in scientific knowledge of impaired healing and the ability of clinicians to reduce morbidity, loss of limb and mortality. Therefore, taking stock of what is known and what is needed to improve understanding of chronic wounds and their associated failure to heal is crucial to ensuring better treatments and outcomes.

Abstract
Chronic and non-healing wounds pose a great challenge to clinical management and patients. Many studies have explored novel interventions against skin wounds, with bioactive peptides, nanoparticles, and hydrogels arousing considerable attention regarding their therapeutic potential. In this study, the prohealing peptide RL-QN15 was loaded into hollow silica nanoparticles (HSNs), with these HSN@RL-QN15 nanocomposites then combined with zinc alginate (ZA) gels to obtain HSN@RL-QN15/ZA hydrogel. The characteristics, biological properties, and safety profiles of the hydrogel composites were then evaluated. Results showed that the hydrogel had good porosity, hemocompatibility, biocompatibility, and broad-spectrum antimicrobial activity, with the slow release of loaded RL-QN15. Further analysis indicated that the hydrogel promoted skin cell proliferation and keratinocyte scratch repair, regulated angiogenesis, reduced inflammation, and accelerated re-epithelialization and granulation tissue formation, resulting in the rapid healing of both full-thickness skin wounds and methicillin-resistant Staphylococcus aureus biofilm-infected chronic wounds in mice. This peptide-based hydrogel provides a novel intervention for the treatment of chronic skin wounds and shows promise as a wound dressing in the field of tissue regeneration.

Abstract
Wound healing is a complex and dynamic cellular process to restore tissue function. Current treatments for chronic wounds especially diabetic ulcers are expensive, with adverse effects. Recently, numerous researchers have focused on the potential effect of natural products on wound healing. One of them is mangosteen (Garcinia mangostana Linn). It is a well-known tropical fruit that is native to Southeast Asia. The active ingredient of mangosteen pericarp contains xanthones that exhibit a wide range of pharmacological activities, including anti-inflammatory and anti-bacterial properties which are the core elements needed in wound healing. Firstly, this review discusses the concepts of abnormal and normal wound healing mechanisms. Then an in depth observation of the pharmacological activities of mangosteen and its derivatives was presented to study their potentially beneficial applications in the treatment of chronic wound healing which is a contemporary medical issue.

Bacterial cellulose/soybean protein isolate composites with promoted inflammation inhibition, angiogenesis and hair follicle regeneration for wound healing. Int J Biol Macromol 2022; 211:754-766. [PMID: 35469946 DOI: 10.1016/j.ijbiomac.2022.04.118] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 04/12/2022] [Accepted: 04/16/2022] [Indexed: 11/25/2022]
Abstract
Soybean protein, as a safe and low-cost alternative to animal protein, attracts increasing attention in wound healing. In the present study, beta-conglycinin (7S) and glycinin (11S) with high solubility were obtained through separation of soybean protein. Afterward, 7S or 11S modified bacterial cellulose (BC) composites were produced by self-assembly method. Results confirmed the successful self-assembly of soybean protein isolates on the nanofibers of BC. The surface roughness and hydrophilicity of BC/7S and BC/11S decreased compared with native BC. Soybean protein could be steadily released from BC/7S and BC/11S and BC/11S released more soybean proteins than BC/7S. In vitro, BC/7S and BC/11S supported fibroblasts attachment and promoted fibroblasts proliferation and type I collagen expression. In vivo, BC/7S and BC/11S facilitated wound healing and collagen deposition, enhanced angiogenesis and hair follicle regeneration, as well as reduced scar formation and inflammation in full-thickness skin wounds of rats. Moreover, wounds treated with BC/11S showed a faster wound healing rate and more collagen depositions than those of BC/7S, which may be attributed to the larger considerable amount of soybean protein released by BC/11S. These results indicate that BC/7S and BC/11S are potential candidates for wound dressings.

Abstract
An effective wound management strategy needs accurate assessment of wound status throughout the whole healing process. This can be achieved by examining molecular biomarkers including proteins, DNAs, and RNAs. However, existing methods for quantifying these biomarkers such as immunohistochemistry and quantitative polymerase chain reaction are usually laborious, resource-intensive, and disruptive. This article reports the development and utilization of mRNA nanosensors (i.e., NanoFlare) that are topically applied on cutaneous wounds to reveal the healing status through targeted and semi-quantitative examination of the mRNA biomarkers in skin cells. In 2D and 3D in vitro models, the efficacy and efficiency of these nanosensors are demonstrated in revealing the dynamic changes of mRNA biomarkers for different stages of wound development. In mouse models, this platform permits the tracking and identification of wound healing stages and a normal and diabetic wound healing process by wound healing index in real time.

Human Amniotic Mesenchymal Stem Cells and Fibroblasts Accelerate Wound Repair of Cystic Fibrosis Epithelium. Life (Basel) 2022; 12:life12050756. [PMID: 35629422 PMCID: PMC9144497 DOI: 10.3390/life12050756] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/12/2022] [Accepted: 05/16/2022] [Indexed: 12/19/2022] Open
Abstract
Cystic fibrosis (CF) airways are affected by a deranged repair of the damaged epithelium resulting in altered regeneration and differentiation. Previously, we showed that human amniotic mesenchymal stem cells (hAMSCs) corrected base defects of CF airway epithelial cells via connexin (CX)43-intercellular gap junction formation. In this scenario, it is unknown whether hAMSCs, or fibroblasts sharing some common characteristics with MSCs, can operate a faster repair of a damaged airway epithelium. A tip-based scratch assay was employed to study wound repair in monolayers of CFBE14o- cells (CFBE, homozygous for the F508del mutation). hAMSCs were either co-cultured with CFBE cells before the wound or added to the wounded monolayers. NIH-3T3 fibroblasts (CX43+) were added to wounded cells. HeLa cells (CX43-) were used as controls. γ-irradiation was optimized to block CFBE cell proliferation. A specific siRNA was employed to downregulate CX43 expression in CFBE cells. CFBE cells showed a delayed repair as compared with wt-CFTR cells (16HBE41o-). hAMSCs enhanced the wound repair rate of wounded CFBE cell monolayers, especially when added post wounding. hAMSCs and NIH-3T3 fibroblasts, but not HeLa cells, increased wound closure of irradiated CFBE monolayers. CX43 downregulation accelerated CFBE wound repair rate without affecting cell proliferation. We conclude that hAMSCs and fibroblasts enhance the repair of a wounded CF airway epithelium, likely through a CX43-mediated mechanism mainly involving cell migration.

Preparation of shikonin liposome and evaluation of its in vitro antibacterial and in vivo infected wound healing activity. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 99:154035. [PMID: 35286935 DOI: 10.1016/j.phymed.2022.154035] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 02/28/2022] [Accepted: 03/05/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND The emergence of antibiotic resistance over the past decade has made the treatment of Staphylococcus aureus infection difficult. Burn wounds infected with methicillin-resistant S. aureus (MRSA) can cause mortality in animals. Shikonin (SH) has been reported to possess antimicrobial and anti-inflammatory properties, and is also responsible for the process of wound healing. However, the pharmacological mechanism of its wound healing process remains poorly comprehended, hence the probable mechanism deserves further investigation. PURPOSE The current study was designed to develop a novel SH-liposome with improved anti-MRSA effect and to detect its beneficial wound healing effects. STUDY DESIGN In vitro antibacterial tests and in vivo infected wound healing test were conducted. METHODS SH-liposome was produced by the film formation method, and the characteristics were measured using a laser particle size analyzer, transmission electron microscopy, and the dialysis method. Additionally, in vitro antibacterial tests were conducted to investigate the antibacterial effects and the relative mechanism of SH-liposome. Furthermore, the therapeutic effects and bioactivity of SH-liposome in MRSA infected burn wounds were investigated in rats. Sixty-four male Sprague Dawley rats (250 ± 10 g) were randomly divided into four groups, including Group I (control group); Group II (model group); Group III (SH-liposome group) and Group IV (Arnebia oil® group), and the drug treatments were applied topically twice daily for 21 days. Further, full thickness skin biopsies at different periods were collected aseptically to evaluate tissue cytokines, recognize flora, observe histopathological changes, and determine the mechanism underlying the wound healing effects of SH-liposome. The data were analyzed via one-way analysis of variance (ANOVA) and Duncan's multiple range test. RESULTS The results showed that SH-liposome was successful with a drug load of 4.6 ± 0.17%. Moreover, SH-liposome showed a sustained-release behavior and improved antibacterial ability in a dose-dependent manner. For the possible antibacterial mechanism, we observed that SH-liposome achieved antibacterial activity by damaging the integrity of bacterial cell wall and membrane to further disturb the physiological activities of S. aureus. In addition, SH-liposome facilitated wound healing by inhibiting bacterial activities to control infection, regulating the I-κBα/NFκB-p65 pathway to alleviate inflammation, and directly promoting repair in burn wounds. CONCLUSION In conclusion, SH-liposome showed an antibacterial effect against S. aureus, promoted effective healing of infected burn wounds; hence, it could be used as an alternative therapy for drug-resistant infections.
