Abstract
In an aging society with common lifestyle-associated health issues such as obesity and diabetes, chronic wounds pose a frequent challenge that physicians face in everyday clinical practice. Therefore, nonhealing wounds have attracted much scientific attention. Several in vitro and in vivo models have been introduced to deepen our understanding of chronic wound pathogenesis and amplify therapeutic strategies. Understanding how wounds become chronic will provide insights to reverse or avoid chronicity. Although choosing a suitable model is of utmost importance to receive valuable outcomes, an ideal in vivo model capturing the complexity of chronic wounds is still missing and remains a translational challenge. This review discusses the most relevant mammalian models for wound healing studies and provides guidance on how to implement the hallmarks of chronic wounds. It highlights the benefits and pitfalls of established models and maps out future avenues for research.

Abstract
Nauclea officinalis, as a Chinese medicine in Hainan province, had the effect of treating lower limb ulcers, burn infections. In this paper, we studied the effect of Strictosamide (STR), the main bioactive compound in Nauclea officinals, on wound healing and explored its internal mechanism. Firstly, the wound healing potential of STR was evaluated in a rat model, demonstrating its ability to expedite wound healing, mitigate inflammatory infiltration, and enhance collagen deposition. Additionally, immunofluorescence analysis revealed that STR up-regulated the expression of CD31 and PCNA. Subsequently, target prediction, protein-protein interaction (PPI), gene ontology (GO), and pathway enrichment analyses were used to obtain potential targets, specific biological processes, and molecular mechanisms of STR for the potential treatment of wound healing. Furthermore, molecular docking was conducted to predict the binding affinity between STR and its associated targets. Additionally, in vivo and in vitro experiments confirmed that STR could increase the expression of P-PI3K, P-AKT and P-mTOR by activating the PI3K/AKT signaling pathway. In summary, this study provided a new explanation for the mechanism by which STR promotes wound healing through network pharmacology, suggesting that STR may be a new candidate for treating wound.

Abstract
Reactive oxygen species (ROS) are produced during oxidative metabolism in aerobic organisms. Under normal conditions, ROS production and elimination are in a relatively balanced state. However, under internal or external environmental stress, such as high glucose levels or UV radiation, ROS production can increase significantly, leading to oxidative stress. Excess ROS production not only damages biomolecules but is also closely associated with the pathogenesis of many diseases, such as skin photoaging, diabetes, and cancer. Antioxidant peptides (AOPs) are naturally occurring or artificially designed peptides that can reduce the levels of ROS and other pro-oxidants, thus showing great potential in the treatment of oxidative stress-related diseases. In this review, we discussed ROS production and its role in inducing oxidative stress-related diseases in humans. Additionally, we discussed the sources, mechanism of action, and evaluation methods of AOPs and provided directions for future studies on AOPs.

Abstract
Skin wound healing is a dynamic and complex process that involves multiple physiological and cellular events. Grape seed proanthocyanidins (GSP) have strong anti-oxidation and elimination of oxygen free radicals, and have been shown to significantly promote wound healing, but the underlying mechanism remains unclear. Studies have indicated that reactive oxygen species (ROS) acts as an upstream signal to induce mitophagy, suggesting that GSP can regulate mitophagy through the signal pathway. This study aimed to investigate whether GSP regulates mitophagy by down-regulating oxidative stress to promote wound healing. In vivo, GSP treatment accelerated wound healing, granulation tissue formation, collagen deposition, and angiogenesis in mice. Moreover, GSP down-regulated ROS levels and promoted the expression of antioxidant proteins by up-regulating the expression of p-JNK/FOXO3a protein, thereby regulating the expression of mitophagy-related proteins. In vitro, 4 μg/mL GSP showed no apparent toxic effects on cells and effectively reduce the oxidative stress damage of cells induced by H2O2. Western blot and superoxide anion fluorescence probe further confirmed that GSP effectively reduced Dihydroethidium content and up-regulated the expression of antioxidant proteins by activation of p-JNK/FOXO3a protein expression, thereby regulating mitophagy. Taken together, the findings from in vitro and in vivo experiments provide new insights into the promotion of wound healing by GSP.

Abstract
Resveratrol (RSV) is a natural extract that has been extensively studied for its significant anti-inflammatory and antioxidant effects, which are closely associated with a variety of injurious diseases and even cosmetic medicine. In this review, we have researched and summarized the role of resveratrol and its different forms of action in wound healing, exploring its role and mechanisms in promoting wound healing through different modes of action such as hydrogels, fibrous scaffolds and parallel ratio medical devices with their anti-inflammatory, antioxidant, antibacterial and anti-ageing properties and functions in various cells that may play a role in wound healing. This will provide a direction for further understanding of the mechanism of action of resveratrol in wound healing for future research.

Abstract
The compositions and health-beneficial properties of lingonberry leaves (Vaccinium vitis-idaea L.) are well established; however, their proanthocyanidins are still heavily underutilized. Optimizing their delivery systems is key to enabling their wider applications. The present study investigates the phytochemical and 'wound-healing' properties of proanthocyanidin-rich fraction(s) (PRF) from lingonberry leaves as well as the development of optimal dermal film as a proanthocyanidin delivery system. The obtained PRF was subjected to HPLC-PDA and DMAC analyses to confirm the qualitative and quantitative profiles of different polymerization-degree proanthocyanidins. A 'wound healing' in vitro assay was performed to assess the ability of PRF to modulate the wound environment for better healing. Low concentrations of lingonberry proanthocyanidins were found to accelerate 'wound' closures, while high levels inhibited human fibroblast migration. Fifteen dermal films containing PRF were prepared and evaluated based on their polymer (MC, HEC, PEG 400) compositions, and physical, mechanical, and biopharmaceutical properties using an experimental design. The composition containing 0.30 g of MC, 0.05 g of HEC, and 3.0 g of PEG 400 was selected as a promising formulation for PRF delivery and a potentially effective functional wound dressing material, supporting the need for further investigations.

Abstract
OBJECTIVE In this study, the effects of resveratrol topical ointment on wound contraction and histopathology of full-thickness cutaneous burn wounds were evaluated. METHOD Adult albino rats were grouped into four equal-sized groups of 15 rats each, as follows: Group A-no wound, no treatment (control); Group B-1% silver sulphadiazine; Group C-5% resveratrol, and Group D-wound without treatment (control). A burn wound measuring 23.5mm was created on the skin at the dorsum of all rats in groups B-D after shaving. The percentage of wound contraction was measured using a digital Vernier Caliper on days 1, 3, 5, 7, 10, 14, 16, 18 and 21, post-wounding. From each group, five rats were then euthanised and tissue samples of the skin, liver and kidney were collected in 10% buffered formalin for histopathology. RESULTS The percentage of wound contraction was significant (p<0.05) on 7, 14 and 18 days post treatment. Histopathologically, 5% resveratrol topical ointment application resulted in a thicker epidermis with neovascularisation and an increased collagen distribution. Resveratrol topical ointment ameliorated the extent of hepatocellular and nephrotubular injuries following burn-induced hepatocellular and acute kidney injuries. CONCLUSION In this study, topical application of 5% resveratrol ointment appeared to enhance burn wound healing by increasing the rate of wound contraction through collagen fibre synthesis, granulation tissue formation and epithelial regeneration.

Abstract
Under normal circumstances, wound healing can be summarized as three processes. These include inflammation, proliferation, and remodeling. The vast majority of wounds heal rapidly; however, a large percentage of nonhealing wounds have still not been studied significantly. The factors affecting wound nonhealing are complex and diverse, and identifying an effective solution from nature becomes a key goal of research. This study aimed to highlight and review the mechanisms and targets of natural products (NPs) for treating nonhealing wounds. The results of relevant studies have shown that the effects of NPs are associated with PI3K-AKT, P38MAPK, fibroblast growth factor, MAPK, and ERK signaling pathways and involve tumor growth factor (TNF), vascular endothelial growth factor, TNF-α, interleukin-1β, and expression of other cytokines and proteins. The 25 NPs that contribute to wound healing were systematically summarized by an inductive collation of the six major classes of compounds, including saponins, polyphenols, flavonoids, anthraquinones, polysaccharides, and others, which will further direct the attention to the active components of NPs and provide research ideas for further development of new products for wound healing.

Abstract
Chronic inflammation is one of the hallmarks of chronic wounds and is tightly coupled to immune regulation. The dysregulation of the immune system leads to continuing inflammation and impaired wound healing and, subsequently, to chronic skin wounds. In this review, we discuss the role of the immune system, the involvement of inflammatory mediators and reactive oxygen species, the complication of bacterial infections in chronic wound healing, and the still-underexplored potential of natural bioactive compounds in wound treatment. We focus on natural compounds with antioxidant, anti-inflammatory, and antibacterial activities and their mechanisms of action, as well as on recent wound treatments and therapeutic advancements capitalizing on nanotechnology or new biomaterial platforms.

Abstract
Resveratrol is a well-known polyphenol that harbors various health benefits. Besides its well-known anti-oxidative potential, resveratrol exerts anti-inflammatory, pro-angiogenic, and cell-protective effects. It seems to be a promising adjuvant for various medical indications, such as cancer, vascular, and neurodegenerative diseases. Additionally, resveratrol was shown to display beneficial effects on the human skin. The polyphenol is discussed to be a feasible treatment approach to accelerate wound healing and prevent the development of chronic wounds without the drawback of systemic side effects. Despite resveratrol's increasing popularity, its molecular mechanisms of action are still poorly understood. To take full advantage of resveratrol's therapeutic potential, a profound knowledge of its interactions with its targets is needed. Therefore, this review highlights the resveratrol-induced molecular pathways with particular focus on the most relevant variables in wound healing, namely inflammation, oxidative stress, autophagy, collagen proliferation and angiogenesis.

[PMID: 34671732 PMCID: PMC8459329 DOI: 10.1039/d1md00100k] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Accepted: 06/04/2021] [Indexed: 12/22/2022] Open
Abstract
Hydrogels are proving to be very versatile as wound healing devices. In addition to their capabilities of providing a moist cellular environment and adaptive mechanical properties mimicking the extracellular matrix, they allow the incorporation of small molecules, which have potential impacts on cellular behaviour, in their nanostructures. This strategy can allow for specific targeting of the different stages of wound healing namely hemostasis, inflammation, and proliferative and remodelling phases. The latter include interlinked processes such as angiogenesis, collagen synthesis, growth factor release, collagen maturation and re-epithelialization. In this review, we attempt to match the mechanisms of action of natural molecules/extracts to the different stages of wound healing so that they can be used in a novel approach of multiphase-directed tissue regeneration using loaded hydrogel scaffolds.

Abstract
Resveratrol is a well‐known antioxidant that harbours many health beneficial properties. Multiple studies associated the antioxidant, anti‐inflammatory, and cell protective effects of resveratrol. These diverse effects of resveratrol are also potentially involved in cutaneous wound healing, scarring, and (photo‐)aging of the skin. Hence, this review highlighted the most relevant studies involving resveratrol in wound healing, scarring, and photo‐aging of the skin. A systematic review was performed and the database PubMed was searched for suitable publications. Only original articles in English that investigated the effects of resveratrol in wound healing, scarring, and (photo‐)aging of the skin were analysed. The literature search yielded a total of 826 studies, but only 41 studies met the inclusion criteria. The included studies showed promising results that resveratrol might be a feasible treatment approach to support wound healing, counteract excessive scarring, and even prevent photo‐aging of the skin. Resveratrol represents an interesting and promising novel therapy regime but to confirm resveratrol‐associated effects, more evidence based in vitro and in vivo studies are needed.

Abstract
Background A moisturizer application during the healing process after a tattoo session is a common practice to help wound healing and to reduce discomfort sensations. This practice was recently recommended by the standard European guidelines on tattoos, with the use of an adapted ointment to keep the site moist. Aims To assess the efficacy and the tolerability of a specific dermo‐cosmetic product (Cicabio Pommade, Laboratoire Bioderma, NAOS, France) in tattoo aftercare. Patients/Methods Thirty subjects included in this survey applied the product immediately after the tattoo session for 14 days. The objective symptoms (redness, edema, skin repair quality) were assessed by the tattooist and the subjects. The subjective symptoms, discomfort sensations (pain, itching, burning sensations, tingling), soothing, moisturizing, and undesirable effects were assessed by the tattooed individuals. Results After 14 days of application, redness was absent for 100% and 96% of subjects according to the tattoo artist and the subjects, respectively, and edema had completely disappeared for both assessors. Most of the subjects rated the skin quality repair and the aesthetic outcomes as very good to excellent. Soothing and moisturizing effects were observed as early as the first day. The effects were maintained over 14 days. Discomfort sensations were judged absent to slight in 96%–100% of cases after 7 days. They were assessed as absent to slight in all cases for pain, itching, and tingling, and in 96% for burning sensations after 14 days. The product was very well tolerated by 87% of the subjects. Conclusions Our survey demonstrates that this dermo‐cosmetic product is suitable for tattooed skin aftercare as it reduced skin discomfort as soon as the first day and led to a good skin quality repair while being well tolerated.

Abstract
Background Vitis vinifera (black grape) is cultivated worldwide and has numerous oral and therapeutic applications. It has proven anti-inflammatory, antioxidant, antimicrobial, and wound healing properties. The aim of this study was to investigate the effect of black grape seed (hydroalcoholic) extract (BGSE) and black grape seed oil (BGSO) on experimental colitis. Methods BGSE (50, 100, and 200 mg/kg) and BGSO (2, 4, and 8 mL/kg) were administered orally (p.o.) in groups of six male Wistar rats, 2 h before induction of colitis and continued further for 4 days. Prednisolone (4 mg/kg) and mesalamine (100 mg/kg) were used as reference drugs. Weight/length of colons, macroscopic and histopathologic indices, and biochemical parameters including myeloperoxidase (MPO) and malondialdehyde (MDA) were evaluated. Results All doses of BGSE and BGSO significantly decreased the colon weight, ulcer index, and total colitis index in comparison with the control group, although greater doses of both fractions had more significant protection. Data of MPO activity revealed that all treated groups with the exception of BGSE (50 mg/kg) and BGSO (2 mL/kg) showed a meaningful decline in comparison with the control group. Concerning the MDA values in colonic tissue, it was demonstrated that BGSE (100, 200 mg/kg) and BGSO (8 mL/kg) caused a significant dip in this oxidative stress parameter. Conclusions Oral administration of BGSE and BGSO had an appropriate anti-inflammatory effect and so could be considered as a suitable candidate for treating or preventing ulcerative colitis. Furthermore, detailed studies are warranted to explore the exact mechanism of action and clinical preference of these compounds.

A Review of the Potential Benefits of Plants Producing Berries in Skin Disorders. Antioxidants (Basel) 2020; 9:antiox9060542.

Abstract
During the last 30 years, berries have gained great attention as functional food against several risk factors in chronic diseases. The number of related publications on Pubmed rose from 1000 items in 1990 to more than 11,000 in 2019. Despite the fact that a common and clear definition of "berries" is not shared among different scientific areas, the phytochemical pattern of these fruits is mainly characterized by anthocyanins, flavanols, flavonols, and tannins, which showed antioxidant and anti-inflammatory properties in humans. Skin insults, like wounds, UV rays, and excessive inflammatory responses, may lead to chronic dermatological disorders, conditions often characterized by long-term treatments. The application of berries for skin protection is sustained by long traditional use, but many observations still require a clear pharmacological validation. This review summarizes the scientific evidence, published on EMBASE, MEDLINE, and Scholar, to identify extraction methods, way of administration, dose, and mechanism of action of berries for potential dermatological treatments. Promising in vitro and in vivo evidence of Punica granatum L. and Vitis vinifera L. supports wound healing and photoprotection, while Schisandra chinensis (Turcz.) Baill. and Vaccinium spp. showed clear immunomodulatory effects. Oral or topical administrations of these berries justify the evaluation of new translational studies to validate their efficacy in humans.

Abstract
The winemaking process produces a huge number of pomaces that generally are used for energy purposes. Further valuable applications such as health-promoting properties are still under investigation. The seeds of the white berries of Mantonico and Pecorello cv. were extracted in a Soxhlet apparatus, using n-hexane and chloroform as solvents. Extracts were characterized by NMR and GC-MS analyses. They were assayed in vitro as wound healing and anti-inflammatory agents in HaCaT and RAW 264.7 cell lines, respectively. n-hexane Mantonico extract resulted in the most interesting wound healing sample, while n-hexane Pecorello, containing a good number of carotenoids, resulted in a good anti-inflammatory candidate. These preliminary findings underlined the benefit of grape seed extracts valorization due to their health-promoting properties.

Abstract
Excessive inflammation and reduced angiogenesis are two major obstacles in burn wound healing and skin regeneration. Here we report the fabrication and application of a sophisticated hydrogel from chemically modified hyaluronic acid (HA), dextran (Dex), and β-cyclodextrin (β-CD) integrating resveratrol (Res) and vascular endothelial growth factor (VEGF) plasmid as the anti-inflammatory and pro-angiogenic components for burn wounds. Firstly, covalent alterations were conducted to obtain methacrylic acid anhydride modified HA (HAMA), N-hydroxyethylacrylamide (HEAA) modified Dex (Dex-HEAA), and poly(ethylene glycol) methyl acrylate (526) modified β-CD (526-β-CD), respectively. Secondly, anti-inflammatory substance Res was embedded into the lipophilic central cavity of 526-β-CD to achieve a complex of 526-β-CD-Res. Then hydrogels with different HAMA, Dex-HEAA, and 526-β-CD-Res ratios were generated via UV irradiation. Lastly, plasmid DNA encoded with vascular endothelial growth factor (pDNA-VEGF) conjugating with polyethylenimine was loaded into the hydrogel scaffold. Combining the benefits of all components of the scaffold, the hydrogel embedded with Res and VEGF (Gel-Res/pDNA-VEGF) accelerated the splinted excisional burn wound healing, particularly by inhibiting inflammation response and promoting microvascular formation while being biocompatible. The Res and VEGF gene loaded hydrogel system can be considered as a promising wound dressing for the treatment of various types of wounds. STATEMENT OF SIGNIFICANCE: Combining the benefits of all components of the scaffold, the hydrogel embedded with Res and VEGF (Gel-Res/pDNA-VEGF) accelerated the splinted excisional burn wound healing, particularly by inhibiting inflammation response and promoting microvascular formation while being biocompatible. The Res and VEGF gene loaded hydrogel system can be considered as a promising wound dressing for the treatment of various types of wounds.

Abstract
Grapes are one of the most highly consumed fruits across the world. In ancient Europe the leaves and the sap of grape plants has been used in traditional treatment for ages. Besides being a wellspring for vitamins and fibre, the skin and seeds of grapes are highly rich in Polyphenols specifically proanthocyanidins, which can be used as a functional ingredient to address various health issues by boosting the natural bio-processes of the body. Since, grape seeds are by product of wine making companies therefore can be easily procured. The present review article briefly describes the various pharmacological activities of grape seed extract and different experimental studies were done which supports the beneficial health qualities of the extract. Through different and various studies, it was proved that the proanthocyanidin rich grape seed extract provides benefits against many diseases i.e. inflammation, cardiovascular disease, hypertension, diabetes, cancer, peptic ulcer, microbial infections, etc. Therefore, beside from using it as a nutraceutical or cosmeceutical, as a result they may have a potential to substitute or complement in currently used drugs in the treatment of diseases by developing it into other successful pharmaceutical formulations for better future prospective.

Abstract
The skin is directly exposed to the polluted atmospheric environment, and skin diseases, such as atopic dermatitis and acne vulgaris, can be induced or exacerbated by airborne particulate matter (PM). PM can also promote premature skin aging with its accompanying functional and morphological changes. PM-induced skin diseases and premature skin aging are largely mediated by reactive oxygen species (ROS), and the harmful effects of PM may be ameliorated by safe and effective natural antioxidants. Experimental studies have shown that the extracts and phenolic compounds derived from many plants, such as cocoa, green tea, grape, pomegranate, and some marine algae, have antioxidant and anti-inflammatory effects on PM-exposed cells. The phenolic compounds can decrease the levels of ROS in cells and/or enhance cellular antioxidant capacity and, thereby, can attenuate PM-induced oxidative damage to nucleic acids, proteins, and lipids. They also lower the levels of cytokines, chemokines, cell adhesion molecules, prostaglandins, and matrix metalloproteinases implicated in cellular inflammatory responses to PM. Although there is still much research to be done, current studies in this field suggest that plant-derived phenolic compounds may have a protective effect on skin exposed to high levels of air pollution.

Flavonoids are naturally active substances that form a large class of phenolic compounds abundant in certain foods. Black rice (Oryza sativa L.) contains high levels of anthocyanin polyphenols, which have beneficial effects on health owing to their antioxidant properties. The breakdown of collagenous networks with aging or skin deterioration results in the impairment of wound healing in the skin. Accordingly, reviving stagnant collagen synthesis can help maintain dermal homeostasis during wound healing. This study presents an assessment of the cellular activity of anthocyanins (ANT) extracted from Oryza sativa L., providing information necessary for the development of new products that support natural healing processes. The relative composition of ANT from Oryza sativa L. was determined by high-performance liquid chromatography/diode array detection. ANT promoted the migration of rat dermal fibroblasts (RDFs) and demonstrated antioxidant properties. ANT increased the mRNA expression of collagen type I alpha 2 (COL1A2) and upregulated type I collagen protein levels in H2O2-stimulated RDFs without cytotoxicity. Compared with the untreated group, treatment of RDFs with ANT in the presence of H2O2 led to the activation of signaling pathways, including the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) and Akt, whereas it significantly (p < 0.001) inhibited the phosphorylation of IκBα and suppressed the activation of the nuclear factor-kappa B (NF-κB) subunits, p50 and p65, which are transcription factors responsible for inflammation. Taken together, our findings suggest that ANT from Oryza sativa L. have anti-inflammatory properties and antiaging potential by modulating type I collagen gene expression and suppressing H2O2-induced NF-κB activation in skin fibroblasts.

Prophylactic NS-21 maintains the skin moisture but does not reduce the severity of radiation dermatitis in patients with head and neck cancer: a randomized control trial. Radiat Oncol 2019; 14:90. [PMID: 31146741 PMCID: PMC6543645 DOI: 10.1186/s13014-019-1302-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Accepted: 05/22/2019] [Indexed: 12/22/2022] Open
Abstract
Background To evaluate the practicality of NS-21 cream with regard to its skin-related toxicity in patients with head and neck cancer (HNC) who are undergoing concurrent chemoradiation therapy (CCRT) or radiotherapy (RT). Methods Between July 2015 and November 2017, 30 HNC patients who underwent RT or CCRT were randomly allocated to receive either NS-21 or control treatment on their irradiated skin three times per day, starting at the initiation of RT or CCRT and ending 2 weeks after the completion of RT or until the appearance of grade 3 acute radiation dermatitis (ARD). Dermatitis was recorded weekly according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Skin humidity was monitored by a digital moisture meter. The generalized estimating equation (GEE) and logit link function method were used for statistical analysis. Results No serious adverse events were observed in either group. Itching dermatitis occurred on the right lower neck in one patient of the NS-21 group during the 3rd week of CCRT, but the severity was mild. The median skin moisture value at the time of the final treatment was significantly different between the study and control groups (30.6 vs. 27.3, p = 0.013). Additionally, there was an inverse relationship between skin moisture and ARD grade (B = -0.04, p = 0.005). The incidence of ARD at the time of the last treatment was not significantly different between the study and control groups (6.7% vs 26.7%, p = 0.165). The risk of grade 3 ARD for skin that had received an irradiation dose of 47–70 Gy was higher than that of skin that had received an irradiation dose ≤46 Gy (OR = 31.06, 95% CI =5.95–162.21, p < 0.001). Nevertheless, the risk of ARD was not significantly different between the groups (OR = 0.38, 95% CI = 0.08–1.74, p = 0.212). Conclusions NS-21 was well tolerated and effective for the maintenance of skin moisture; however, there was no statistically significant reduction in the risk of ARD in HNC patients undergoing RT or CCRT when compared with HNC patients in the control group. Trial registration The study was approved by the Institutional Review Board of Far Eastern Memorial Hospital (FEMH-IRB, 104048-F), Registered 1st June 2015,

Abstract
Grape-seed extracts contain rich flavonoids with oligomeric proanthocyanidins (OPC). In this study, OPC containing hydrogel scaffolds can function as a natural photothermal agent for melanoma therapy and bioactive biomaterial for wound healing. Inspired by grape-seed extracts, OPC were explored as a photothermal agent and endowed the hydrogel scaffolds with excellent and controlled photothermal ability. The rheological property of the hydrogel scaffolds responded to irradiation time of near infrared (NIR) laser, and OPC contents. The compressive mechanical property of the hydrogel scaffolds was well modulated by NIR laser irradiation with different impact durations. The controlled high temperature induced by OPC-containing hydrogel scaffolds under NIR laser irradiation could effectively kill melanoma cells and suppress tumor growth. In addition, OPC-containing hydrogel scaffolds supported the proliferation and migration of human dermal fibroblasts and human umbilical vein endothelial cells, as well as obviously promoted angiogenesis and skin regeneration in both tumor-caused and chronic wounds. Therefore, OPC-containing hydrogel scaffolds possessed controlled photothermal, rheological, and compressive mechanical properties under NIR laser stimuli, as well as excellent biocompatibility and bioactivity for melanoma therapy and wound healing.

Abstract
BACKGROUND and purpose: Complications of the delayed recovery of cesarean section (CS) wound can include stress, discomfort, and dissatisfaction of the mother in the postpartum period. This study tried to determine the effect of grape seed extract ointment on CS wound healing. MATERIALS AND METHODS This is a double-blind, randomized, controlled clinical trial incorporating 129 women eligible for CS in eastern Iran. Participants were selected through convenience sampling method and were subsequently randomly assigned into three groups: 2.5% grape seed extract ointment, 5% grape seed extract ointment, and petrolatum. CS wound healing indices were assessed before the intervention, and 6 and 14 days after the intervention using the REEDA scale (redness, edema, ecchymosis, discharge, and approximation). RESULTS The mean scores on days 6 and 14 after intervention were respectively 2.02 ± 0.52 and 0.98 ± 0.61 in the 5% ointment group, 2.83 ± 0.54 and 1.58 ± 0.67 in the 2.5% ointment group, and 2.91 ± 0.51 and 1.55 ± 0.74 in the petrolatum group. While the mean score in the 5% ointment group was significantly different from those of 2.5% ointment and petrolatum groups (P < 0.001), the mean score in the 2.5% ointment group was not significantly different from that of the petrolatum group on days 6 and 14 after intervention (P = 0.38 and P = 0.79, respectively). CONCLUSION The current results suggest that 5% grape seed extract may have beneficial therapeutic effects in promoting CS wound healing.

Abstract
Soft tissue injuries are among the most difficult orthopaedic conditions to treat, and regenerative medicine holds the promise of better treatments of these injuries. There is therefore a requirement for substrates and porous scaffolds which provide an appropriate chemical and mechanical environment for cell attachment, growth, proliferation and differentiation. In this study, cross-linked porous gelatin-chitosan (Gel/Chi) scaffolds with high porosity (>90%) were fabricated and their internal morphology, pore sizes and porosities were characterized using scanning electron microscopy (SEM), micro computed tomography (micro-CT) and mercury intrusion porosimetry. The cross-linking agents chosen for this study were Procyanidin (PA), chosen for its biocompatibility, and glutaraldehyde (GA), chosen for comparison as a highly effective cross-linker. Concentrations of these cross-linkers varied from 0.1% to 1% (w/v) and controls had the same gelatin-chitosan blend but were untreated. It was found that the water absorption of cross-linked scaffolds decreased as the cross-linker concentration increased and in vitro collagenase degradation test showed both cross-linkers increased the biostability of the scaffolds. Scaffolds were also tested under compressive load to investigate their resistance to deformation. The results indicated that both cross-linkers increase the stiffness of the scaffolds both initially and at higher strains, but GA cross-linked scaffolds had a higher compressive stiffness than scaffolds cross-linked with PA for a given concentration. Results from cyclic compression and stress relaxation tests showed that PA cross-linked scaffolds recover more rapidly after deformation. 3T3 fibroblasts were cultured on the scaffolds to assess cytotoxicity and biocompatibility. The results indicated that PA was non-cytotoxic and promoted the attachment and proliferation of the seeded cells, while fewer cells were seen on GA cross-linked scaffolds, indicating that the GA had conferred some cytotoxicity. PA cross-linked Gel/Chi porous scaffolds show promise as three dimentional porous scaffolds in tissue engineering, as porous substrates for biomimetic culture environments, and for regenerative medicine applications, due to their excellent biocompatibility and easily adaptable mechanical properties, as well as their lower cost compared to collagen and fibrin based substrates.

Abstract
To maximize the effectiveness of any complementary therapy in treating chronic wounds, the clinician must fully appreciate the scientific basis in which this treatment modality influences wound healing. The biological changes influenced by phytochemical compounds can have a positive effect on wound healing, which often depends on extract selection and clinical application. A sound understanding of the physiological changes that are associated with phytochemical compounds will help the clinician to make an appropriate extract selection and guide treatment decisions.Tissue adhesion has long been considered a key step in determining a bacterium's pathogenicity. The process of preventing infections by decreasing bacterial-tissue adhesion has been reported in the literature, with particular focus on the antibacterial effects of ingested cranberry juice. Cranberry juice has been studied primarily as a "home remedy" in the treatment of urinary tract infection with its antiadhesion and/or antibacterial effects in a chronic wound needing further investigation.

Abstract
The study of wound‑healing plants has acquired an interdisciplinary nature with a systematic investigational approach. Several biochemicals are involved in the healing process of the body, including antioxidants and cytokines. Although several pharmaceutical preparations and formulations are available for wound care and management, it remains necessary to search for efficacious treatments, as certain current formulations cause adverse effects or lack efficacy. Phytochemicals or biomarkers from numerous plants suggest they have positive effects on different stages of the wound healing process via various mechanisms. Several herbal medicines have displayed marked activity in the management of wounds and various natural compounds have verified in vivo wound healing potential, and can, therefore, be considered as potential drugs of natural origin. Chromolaena odorata (L.) R.M. King and H. Robinson is considered a tropical weed. However, it exhibits anti‑inflammatory, antipyretic, analgesic, antimicrobial, cytotoxic and numerous other relevant medicinal properties on an appreciable scale, and is known in some parts of the world as a traditional medicine used to treat various ailments. To understand its specific role as nature's gift for healing wounds and its contribution to affordable healthcare, this plant must be scientifically assessed based on the available literature. This review aims to summarize the role of C. odorata and its biomarkers in the wound healing activities of biological systems, which are crucial to its potential future drug design, development and application for the treatment of wounds.

Abstract
Background A combination of the oils of sesame, hemp, wild pistachio, and walnut has been used for treatment of skin disorders, including wound burns, in some parts of Kerman, Iran. Evaluation of this remedy in the form of a pharmaceutical formulation in animal models can pave the way for its future application in wound burn healing in humans. Objectives This experimental study investigated the healing potential of a new formula (NF) based on folk medicine from Iran for the treatment of third degree burns in mice. The formula was a combination of the oils of four plants: sesame (Sesamum indicum L.), wild pistachio (Pistacia atlantica Desf.), hemp (Cannabis sativa L.), and walnut (Juglans regia L.) Methods Twenty-four mice were selected based on simple random sampling. Twenty-five percent of the total body surface area was burned by exposure to boiling water, according to the Walker-Mason method. NF and silver sulfadiazine (the positive control) were applied topically twice a day for 21 days. The burned area in the negative control group was left untreated. Epithelialization time and the percent of wound contraction were measured during the treatment period. The process of wound repairing was evaluated using histological (H and E and trichrome staining) and immunohistological (anti-pancytokeratin) methods. Results When compared to the controls, NF significantly improved wound contraction after day 10. Epithelialization time in the NF group was significantly faster than in the other groups (20 vs. 25.5 days) (P < 0.001). Histopathological and immunohistochemical findings confirmed the efficacy of the NF. Conclusions A new therapeutic remedy was introduced for the treatment of burn wounds. Further clinical and molecular studies are suggested to determine the exact mechanism(s) involved in the burn wound healing effect of NF.

Abstract
The final goal of this study was to develop antimicrobial food-contact materials based on a natural phenolic compound (tannic acid) and chitin, which is the second most abundant polysaccharide on earth, using an interfacial assembly approach. Chitin film has poor antibacterial and antioxidant ability, which limits its application in industrial fields such as active packaging. Therefore, in this study, a novel one-step green procedure was applied to introduce antibacterial and antioxidant properties into a chitin film simultaneously by incorporation of tannic acid into the chitin film through interfacial assembly. The antibacterial and antioxidant behavior of chitin film has been greatly enhanced. Hydrogen bonds and hydrophobic interaction were found to be the main driving forces for interfacial assembly. Therefore, controlled interfacial assembly of tannic acid onto a chitin film demonstrated a good way to develop functional materials that can be potentially applied in industry.

Abstract
Patients with condyloma acuminata (CA) during pregnancy represent a special risk group. The outcomes of many treatment methods for such cases are not satisfactory. The purpose of the present study was to evaluate the treatment outcome and safety of cryotherapy combined with proanthocyanidins (PCs) for CA in pregnant women. In this study, 46 pregnant women with CA were treated with cryotherapy combined with PCs. The lesions were sprayed with liquid nitrogen until the color of the wart changed from flesh colored to purple. A PC-containing formulation was then sprayed onto a non-woven fabric or single-layer gauze and applied to the affected area. The PC treatment was applied for 20 min, 2 or 3 times per day. All patients were followed up at 1 and 3 months. No visible warts remained after the cryotherapy and PC treatment. At the 1-month follow-up, only 1 case of recurrence was identified. At 3 months, 5 cases of recurrence were identified, and the recurrence rate was 10.9%. The satisfaction rate of the patients was 94% at 1 month and 87% at 3 months after treatment. All pregnancies resulted in healthy live births without delivery complications. Cryotherapy combined with PCs is indicated to be a safe and effective procedure and may serve as a treatment option for pregnant women with CA.

Abstract
PURPOSE To evaluate the effects of angico bark extract (Anadenanthera colubrina var. cebil) in the healing process of the skin of rats. METHODS Twenty adult male rats were divided into four groups of five animals each, according to the respective postoperative days, as follow: G4, G7, G14 and G21. Each group received two incisions on skin and subcutaneous tissue in the right and left antimere of the thoracic region, separated by a distance of 2 cm. The right lesion was treated daily with saline and the left with the angico alcoholic extract (5%). At the end of each experimental period, the animals were euthanized and fragments of the wound area with the edges were removed, fixed in 10% formaldehyde solution and processed for paraffin embedding. Histological sections (5 μm of thickness) were stained with hematoxylin and eosin (HE), Gomori trichromic and picrosisirus red for morphological and morphometric analyses. Statistical analysis was done by ANOVA and Tukey-Kramer test (p<0.05). RESULTS Morphological analysis showed larger fibroblasts and a higher concentration of collagen fibers in skyn wounds treated with the angico extract. Morphometric analysis demonstrated a significant increase in the number of fibroblasts at 7th and collagen in 7th and 14th days (p<0.01) in wounds treated with the angico extract. CONCLUSION The angico alcoholic extract (Anadenanthera colubrina var. cebil) induces the acceleration of wound healing in skin wounds of rats.

The sustained delivery of resveratrol or a defined grape powder inhibits new blood vessel formation in a mouse model of choroidal neovascularization. Molecules 2014; 19:17578-603.

Abstract
The objective of this study was to determine whether resveratrol or a defined, reconstituted grape powder can attenuate the formation of new blood vessels in a mouse model of choroidal neovascularization (CNV). To accomplish this objective, C57BL/6J mice were randomized into control or treatment groups which received either resveratrol or grape powder by daily oral gavage, resveratrol or grape powder delivered ad libitum through the drinking water, or resveratrol by slow release via implanted osmotic pumps. A laser was used to rupture Bruch’s membrane to induce CNV which was then detected in sclerochoroidal eyecups stained with antibodies against intercellular adhesion molecule-2. CNV area was measured using fluorescence microscopy and Image J software. Ad libitum delivery of both resveratrol and grape powder was shown to significantly reduce the extent of CNV by 68% and 57%, respectively. Parallel experiments conducted in vitro demonstrated that resveratrol activates p53 and inactivates Akt/protein kinase B in choroidal endothelial cells, contributing to its anti-proliferative and anti-migratory properties. In addition resveratrol was shown to inhibit the formation of endothelial cell networks, augmenting its overall anti-angiogenic effects. The non-toxic nature of resveratrol makes it an especially attractive candidate for the prevention and/or treatment of CNV.

Abstract
BACKGROUND Reducing the wound healing time is crucial in wound as it lowers the chance of infection and decreases complications and cost. Grape seed extract has the ability to release endothelial growth factor and its topical application results in contraction and closure of the skin wound. Furthermore, it possesses antioxidant and antibacterial properties. In several studies it has been proved effective in animals. Therefore, due to low side effects and recognition of herbal medicine, we decided to evaluate the effect of grape seed extract 2% herbal cream on human skin lesions. MATERIALS This study is a double blind clinical trial conducted on two groups of treatment and placebo. Surgery was performed on skin lesions such as skin tags and moles which were found on the neck, trunk and limbs (except for face). After enrollment and obtaining informed consent from participants, they were randomized into two groups of treatment and placebo. Excision of the lesions was done by surgical scissors. The lesions got restored by secondary intention method. After the first day of treatment, the patients were visited on the 3rd, 7th, 10th, 14th, and 21st day. Grape seed extract cream 2% was produced and coded by the Faculty of Pharmacy, Ahvaz University of Medical Sciences. In order to compare the two groups, T-test was used. For time assessing, analysis of variance with repeated measures was employed. RESULTS The results showed complete repair of wounds averagely on day 8 for the treatment group and on day 14 for the placebo group, which was clearly significant in terms of statistical difference (p=0.00). CONCLUSION Proanthocyanidins in grape seed extract trigger the release of vascular endothelial growth factor and its topical application causes wound contraction and closure. Curing skin lesions with grape seed extract caused proliferation areas with protected boundaries in epithelium, increased cell density and increased deposition of connective tissue at the wound site which in general improves cellular structure in wound. In addition, its anti-inflammatory and anti-microbial properties are effective in wound healing.

Abstract
Methanolic avocado (Persea americana Mill., Lauraceae) seed extracts were separated by preparative HSCCC. Partition and HSCCC fractions were principally characterized by LC-ESI-MS/MS analysis. Their in vitro influence was investigated on proliferation, differentiation, cell viability, and gene expression on HaCaT and normal human epidermal keratinocytes (NHEK) and normal human dermal fibroblasts (NHDF). The methanol-water partition (M) from avocado seeds and HSCCC fraction 3 (M.3) were mostly composed of chlorogenic acid and its isomers. Both reduced NHDF but enhanced HaCaT keratinocytes proliferation. HSCCC fraction M.2 composed of quinic acid among chlorogenic acid and its isomers inhibited proliferation and directly induced differentiation of keratinocytes as observed on gene and protein level. Furthermore, M.2 increased NHDF proliferation via upregulation of growth factor receptors. Salidrosides and ABA derivatives present in HSCCC fraction M.6 increased NHDF and keratinocyte proliferation that resulted in differentiation. The residual solvent fraction M.7 contained among low concentrations of ABA derivatives high amounts of proanthocyanidins B1 and B2 as well as an A-type trimer and stimulated proliferation of normal cells and inhibited the proliferation of immortalized HaCaT keratinocytes.

Abstract
In traditional Iranian medicine (TIM), several edible fruits and spices are thought to have protective and healing effects on peptic ulcer (PU). The present study was conducted to verify anti-PU activity of these remedies. For this purpose, edible fruits and spices proposed for the management of PU in TIM were collected from TIM sources, and they were searched in modern medical databases to find studies that confirmed their efficacy. Findings from modern investigations support the claims of TIM about the efficacy of many fruits and spices in PU. The fruit of Phyllanthus emblica as a beneficial remedy for PU in TIM has been demonstrated to have antioxidant, wound healing, angiogenic, anti-H. pylori, cytoprotective, antisecretory, and anti-inflammatory properties. The fruit of Vitis vinifera has been found to be anti-H. pylori, anti-inflammatory, wound healing, angiogenic, cytoprotective, and antioxidant. The fruit and aril of seed from Myristica fragrans exert their beneficial effects in PU by increasing prostaglandin, modulation of nitric oxide and inflammatory mediators, wound healing, antisecretory, antacid, antioxidant, and anti-H. pylori activities, and improving angiogenesis. Pharmacological and clinical studies for evaluation of efficacy of all TIM fruits and spices in PU and their possible mechanisms of action are recommended.
