Abstract
The wound healing process is characterized by varied biological and molecular cascades including inflammation, tissue proliferation, and remodeling phase. To augment and maintain these cascades, an all-natural matrix system is proposed. Biocompatible biopolymers, sodium alginate and gelatin, were employed to prepare microfibers via extrusion-gelation into a physical crosslinking solution. Curcumin, an anti-inflammatory, anti-oxidant and wound healing agent, was loaded into the fibers as a natural bioactive compound. Curcumin-loaded composite microfibers and blank microfibers were fabricated using biopolymers such as sodium alginate and gelatin. The formulation batches were coded as A1G9-A10G0 according to the varied concentrations of sodium alginate and gelatin. The molecular transitions within the composite microfibers were characterized using FTIR and were further corroborated using molecular mechanics analysis. In mechanical properties tensile strength and elongation-at-break (extensibility) were ranging between 1.08 ± 0.01 to 3.53 ± 0.41 N/mm2 and 3.89 ± 0.18 to 0.61 ± 0.03%. The morphological analysis confirmed the formation and fabrication of the microfibers. In addition, physical evaluation including matrix degradation and entrapment efficiency was performed to give a comparative account of various formulations. The water uptake capacity of the blank and curcumin-loaded composite fibers was found to be in the range of 30.77 ± 2.17 to 100.00 ± 5.99 and 22.34 ± 1.11 to 56.34 ± 4.68, respectively. Composite microfibers presented a cumulative release of 85% in 72 h, confirming the prolonged release potential of the composite fibers. The drug release followed an anomalous (non-Fickian) release behavior asserting the role of degradation and diffusion. In an in vivo full-thickness cutaneous wound model, the composite microfibers provided higher degree of contraction 96.89 ± 3.76% as compared to the marketed formulation (Vicco turmeric cream). In conclusion, this all-natural, alginate-gelatin-curcumin composite has the potential to be explored as a cost-effective wound healing platform.

Abstract
Curcumin is reported to possess excellent efficacy to treat wounds that exhibit impaired healing. Heparin shows high affinity for many growth factors that are key biological mediators during the wound healing process. In this study, we aimed to prepare wound dressing membranes, for sustained release of an exogenous factor curcumin as well as sequestering endogenous growth factors at the wound site, to promote wound healing in diabetic rats. Toward this end, we prepared aligned curcumin-loaded poly(lactide-co-glycolide) (PLGA) nanofiber membranes (PC NFMs), followed by high density surface grafting of heparin to fabricate PLGA/curcumin (PCH) NFMs. Both PC and PCH NFMs show high tensile strength, low cytotoxicity and suitable water vapor transmission rate for application as wound dressings. Nonetheless, the PCH NFM shows higher curcumin release rate than PC due to enhanced hydrophilicity, which leads to higher cell migration rate and induced oxidative stress protection of HS68 fibroblast cells in vitro. In vivo study indicated the PCH exhibits the fastest wound closure rate among all membranes with accelerated re-epithelization rate, higher angiogenesis rate and more collagen deposition at the wound site. The accelerated and better skin tissue regeneration could be suggested to correlate with the multi-functionality of nanofibers, where grafted heparin attracting and stabilizing the growth factors important for wound healing in situ, together with relieving the high oxidative stress and the inflammatory cascade from released curcumin during diabetic wound healing.

Effects of Bacterial Nanocellulose Loaded with Curcumin and Its Degradation Products on Human Dermal Fibroblasts. MATERIALS 2020; 13:ma13214759.

Abstract
Bacterial nanocellulose has found applications in tissue engineering, in skin tissue repair, and in wound healing. Its large surface area enables the adsorption of various substances. Bacterial nanocellulose with adsorbed substances can serve as a substrate for drug-delivery of specific bioactive healing agents into wounds. In this study, we loaded a bacterial nanocellulose hydrogel with curcumin, i.e., an important anti-bacterial and healing agent, and its degradation products. These products were prepared by thermal decomposition of curcumin (DC) at a temperature of 180 °C (DC 180) or of 300 °C (DC 300). The main thermal decomposition products were tumerone, vanillin, and feruloylmethane. Curcumin and its degradation products were loaded into the bacterial nanocellulose by an autoclaving process. The increased temperature during autoclaving enhanced the solubility and the penetration of the agents into the nanocellulose. The aim of this study was to investigate the cytotoxicity and the antimicrobial activity of pure curcumin, its degradation products, and finally of bacterial nanocellulose loaded with these agents. In vitro tests performed on human dermal fibroblasts revealed that the degradation products of curcumin, i.e., DC 180 and DC 300, were more cytotoxic than pure curcumin. However, if DC 300 was loaded into nanocellulose, the cytotoxic effect was not as strong as in the case of DC 300 powder added into the culture medium. DC 300 was found to be the least soluble product in water, which probably resulted in the poor loading of this agent into the nanocellulose. Nanocellulose loaded with pure curcumin or DC 180 exhibited more antibacterial activity than pristine nanocellulose.

Abstract
AIMS The purpose of this research is to fabricate chitosan (CS)/graphene oxide (GO)/curcumin (Cur) 3D scaffolds through the freeze-drying method for wound dressing applications. MAIN METHODS GO is produced by Hammer's method; then, it is characterized by X-ray diffraction and TEM analysis. Fabricated scaffolds are characterized by FTIR, FESEM, AFM, water vapor transmission rate, PBS absorption, contact angle, tensile strength, porosity measurement, biodegradability, and drug release methods. The cell viability and morphology of NIH/3 T3 cells are investigated by WST assay kit and FESEM analysis, and the antibacterial activity of scaffolds is determined by the optical density (OD) method. The photothermal antibacterial activity is characterized by NIR irradiation, too. KEY FINDINGS The mean pore diameter of scaffolds adjusted by the incorporation of about 0-1.5%wt. of GO/Cur nanocomposite into CS matrix, decreasing from 87 to 40 μm that can be attributed to the intermolecular bonds between CS and GO/Cur nanocomposite. Besides, the PBS absorption of scaffolds enhances by the addition of GO/Cur, especially 1% of it. Furthermore, the overall average of cell viability of nanocomposite scaffolds is about 95%, and the FESEM images show that NIH/3T3 fibroblasts well spread on the nanocomposite scaffolds. GO/Cur has a significant influence on the antibacterial activity of CS scaffolds as CS/GO/Cur 0.5 scaffold diminishes the bacterial growth to about 52% of the control sample's growth. SIGNIFICANCE The results evidence the antibacterial CS/GO/Cur scaffolds are excellent supports for cell growth and proliferation, and they could be promising candidates for wound dressing applications.

Abstract
Teeth extractions are often followed by alveolar bone reabsorption, although an adequate level of bone is required for reliable rehabilitations by dental implants. Leukocyte and platelet-rich fibrin (L-PRF) has been widely applied in regenerative procedures and with antibiotic and antioxidant agents could play an essential role in hard and soft tissue healing. In this work, a nanocomposite (Sponge-C-MTR) consisting of a hyaluronate-based sponge loaded with metronidazole (MTR) and nanostructured lipid carriers containing curcumin (CUR-NLC) was designed to be wrapped in the L-PRF™ membrane in the post-extraction sockets and characterized. CUR-NLCs, obtained by homogenization followed by high-frequency sonication of the lipid mixture, showed loading capacity (5% w/w), drug recovery (95% w/w), spherical shape with an average particle size of 112.0 nm, and Zeta potential of -24 mV. Sponge-C-MTR was obtained by entrapping CUR-NLC in a hydrophilic matrix by a freeze-drying process, and physico-chemical and cytocompatibility properties were evaluated. Moreover, the aptitude of CUR and MTR to the penetrate and/or permeate both L-PRF™ and porcine buccal tissue was assessed, highlighting MTR penetration and CUR accumulation promoted by the system. The results positively support the action of nanocomposite in dental tissues regeneration when applied together with the L-PRF™.

Abstract
Curcumin is a unique molecule naturally obtained from rhizomes of Curcuma longa. Curcumin has been reported to act on diverse molecular targets like receptors, enzymes, and co-factors; regulate different cellular signaling pathways; and modulate gene expression. It suppresses expression of main inflammatory mediators like interleukins, tumor necrosis factor, and nuclear factor κB which are involved in the regulation of genes causing inflammation in most skin disorders. The topical delivery of curcumin seems to be more advantageous in providing a localized effect in skin diseases. However, its low aqueous solubility, poor skin permeation, and degradation hinder its application for commercial use despite its enormous potential. Lipid-based nanocarrier systems including liposomes, niosomes, solid lipid nanoparticles, nanostructured lipid carriers, lyotropic liquid crystal nanoparticles, lipospheres, and lipid nanocapsules have found potential as carriers to overcome the issues associated with conventional topical dosage forms. Nano-size, lipophilic nature, viscoelastic properties, and occlusive effect of lipid nanocarriers provide high drug loading, hydration of skin, stability, enhanced permeation through the stratum corneum, and slow release of curcumin in the targeted skin layers. This review particularly focuses on the application of lipid nanocarriers for the topical delivery of curcumin in the treatment of various skin diseases. Furthermore, preclinical studies and patents have also indicated the emerging commercialization potential of curcumin-loaded lipid nanocarriers for effective drug delivery in skin disorders.

Abstract
Nanostructured lipid carriers (NLC) are capable of encapsulating hydrophilic and lipophilic drugs. The present study developed an NLC containing epidermal growth factor (EGF) and curcumin (EGF–Cur-NLC). EGF–Cur-NLC was prepared by a modified water-in-oil-in-water (w/o/w) double-emulsion method. The EGF–Cur-NLC particles showed an average diameter of 331.8 nm and a high encapsulation efficiency (81.1% and 99.4% for EGF and curcumin, respectively). In vitro cell studies were performed using two cell types, NIH 3T3 fibroblasts and HaCaT keratinocytes. The results showed no loss of bioactivity of EGF in the NLC formulation. In addition, EGF–Cur-NLC improved in vitro cell migration, which mimics the wound healing process. Finally, EGF–Cur-NLC was evaluated in a chronic wound model in diabetic rats. We found that EGF–Cur-NLC accelerated wound closure and increased the activity of antioxidant enzymes. Overall, these results reveal the potential of the NLC formulation containing EGF and curcumin to promote healing of chronic wounds.

Abstract
Some of the currently used wound dressings have interesting features such as excellent porosity, good water-absorbing capacity, moderate water vapor transmission rate, high drug loading efficiency, and good capability to provide a moist environment, but they are limited in terms of antimicrobial properties. Their inability to protect the wound from microbial invasion results in wound exposure to microbial infections, resulting in a delayed wound healing process. Furthermore, some wound dressings are loaded with synthetic antibiotics that can cause adverse side effects on the patients. Natural-based compounds exhibit unique features such as good biocompatibility, reduced toxicity, etc. Curcumin, one such natural-based compound, has demonstrated several biological activities such as anticancer, antibacterial and antioxidant properties. Its good antibacterial and antioxidant activity make it beneficial for the treatment of wounds. Several researchers have developed different types of polymer-based wound dressings which were loaded with curcumin. These wound dressings displayed excellent features such as good biocompatibility, induction of skin regeneration, accelerated wound healing processes and excellent antioxidant and antibacterial activity. This review will be focused on the in vitro and in vivo therapeutic outcomes of wound dressings loaded with curcumin.

Abstract
OBJECTIVE Curcumin promotes oral wound healing; however, the underlying mechanism remains unknown. We hypothesized that curcumin may regulate gene expression in human gingival fibroblasts (hGFs). This study investigated the effect of curcumin on the expression of wound healing-related genes, collagen type I (COL1), keratinocyte growth factor (KGF)-1, and epidermal growth factor receptor (EGFR), in the in vitro wound healing model of hGFs, as well as the signaling pathway involved in the regulation of these genes by curcumin. MATERIALS AND METHODS The hGFs were treated with curcumin in the unwounded condition and in the in vitro wound healing model (scratch assay). Gene expression was determined by quantitative polymerase chain reaction. PD98059 was used to elucidate whether extracellular signal regulated kinase (ERK) signaling is involved in the curcumin-regulated gene expression in hGFs. Cell migration was also analyzed by the scratch assay. STATISTICAL ANALYSIS Data were analyzed by independent t-test or one-way analysis of variance (ANOVA) followed by Tukey's Honestly Significant Difference ( HSD) test. RESULTS In unwounded hGFs, curcumin significantly increased KGF-1 and EGFR expressions but not COL1 mRNA expression. Interestingly, curcumin significantly upregulated COL1, KGF-1, and EGFR expressions in the in vitro wound healing model. Furthermore, PD98059 significantly decreased the curcumin-induced COL1 and EGFR expressions, but did not significantly affect KGF-1 upregulation by curcumin. However, hGF migration was not affected by curcumin treatment. CONCLUSION Curcumin induced KGF-1 and EGFR expressions in unwounded hGFs. In the in vitro wound healing model, curcumin upregulated COL1 and EGFR expression via the ERK pathway and increased KGF-1 expression, possibly by an ERK-independent mechanism.

[PMID: 32894821 DOI: 10.1002/iub.2369] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 07/20/2020] [Accepted: 07/31/2020] [Indexed: 01/14/2023]
Abstract
The lysosome is a membrane-enclosed organelle in eukaryotic cells, which has basic pattern recognition for nutrient-dependent signal transduction. In Alzheimer's disease, the already declining autophagy-lysosomal function is exacerbated by an increased need for clearance of damaged proteins and organelles in aged cells. Recent evidence suggests that numerous diseases are linked to impaired autophagy upstream of lysosomes. In this way, a comprehensive survey on the pathophysiology of the disease seems necessary. Hence, in the first section of this review, we will discuss the ultimate findings in lysosomal signaling functions and how they affect cellular metabolism and trafficking under neurodegenerative conditions, specifically Alzheimer's disease. In the second section, we focus on how natural products and their derivatives are involved in the regulation of inflammation and lysosomal dysfunction pathways, including how these should be considered a crucial target for Alzheimer's disease therapeutics.

Abstract
BACKGROUND Reducing the healing time of wounds can decrease the patient's immobility time and their medical costs, leading a faster return of the patients to daily work. OBJECTIVE The aim of the present study is to compare the effect of adipose-derived stem cells and curcumin- containing liposomal nanoparticles with phenytoin on wound healing. METHODS After anesthesia of the rats, open skin ulcers were made by a bistoury blade. Subsequently, stem cells were removed from the adipose tissue of the upper border of the epididymis. The originality of stem cells was then confirmed by the flow cytometry. The fusion method was used to prepare the liposome; and also, nanoliposomal particles were confirmed by using the DLS microscope. The percentage of recovery and the cell count was measured with IMAGEJ. The expression of genes was assessed by PCR. The number of fibroblasts was counted by immunohistochemistry techniques. The amount of collagen was determined by Tri-chromosome staining, and the number of capillaries was enumerated by H & E staining. RESULTS The expression of the TGF-β1 gene, vascular number, wound healing rate and the number of fibroblasts increased significantly in adipose tissue-derived stem cells and curcumin nanoliposome groups (p<0.05); the wound surface was also decreased significantly (p<0.05). CONCLUSION Based on the results of our research, adipose tissue-derived stem cells and curcumin nanoliposomes can heal wounds efficiently.

Abstract
AbstractTurmeric (Curcuma longa Linn) is an herbal medicine which is traditionally used as a spice, food colouring or flavouring agent and widely used for several diseases such as biliary disorders, cough, hepatic disorders, rheumatism, wound healing, sinusitis, diabetes, cardiac disorders and neurological disorder. It belongs to the Zingiberaceae family. Turmeric is a popular domicile remedy used in Indian food, is mainly a native of south-east Asia, is widely cultivated in India, Sri Lanka, Indonesia, China, Jamaica , Peru, Haiti and Taiwan and it is very less expensive. Curcumin is the main principle of turmeric. Curcumin has shown various biological properties pre-clinically and clinically. Curcumin is a highly pleiotropic molecule which can be modulators of various intracellular signalling pathways that maintain cell growth. It has been reported as anti-inflammatory, anti-angiogenic, antioxidant, wound healing, anti-cancer, anti-Alzheimer and anti-arthritis and possesses an excellent safety profile. All previous review articles on curcumin have collected the biological/pharmacological activities but this review article summarises the most interesting in vitro and in vivo studies of curcumin on most running diseases around the whole world.

Abstract
Plastic surgery patients span the nutritional spectrum from generally healthy, nutritionally competent patients to inherently catabolic, nutritionally deficient, and chronic wound patients. Therefore, plastic and reconstructive surgery affords the opportunity to investigate the impact of nutrition across a heterogeneous patient population following a wide variety of procedures. Although patients may be nutritionally deficient in certain vitamins warranting perioperative repletion, other supplements have the potential to benefit all patients, regardless of nutritional status. Despite these putative benefits, there is a dearth of information regarding nutritional optimization, with the limited, available literature focusing mostly on herbal supplements and their potential side effects. A significant barrier to supplement use is the lack of education and available supporting information regarding the indications, contraindications, and physiology of these adjuncts. The goal of this article is to provide a comprehensive, evidence-based review of available nutritional supplements that can be considered for the plastic surgery patient in the perioperative period to optimize surgical outcomes while minimizing risk. Prospective, well-designed studies using validated, high-quality supplements will be critical in determining the significance that perioperative supplementation can have for surgical outcomes. Until well-done prospective studies are performed, the supplement, dose, and duration should be determined on an individual, patient-per-patient basis at the discretion of the operating surgeon.

Abstract
Patients with plasma cell dyscrasias produce free abnormal monoclonal Ig light chains that circulate in the blood stream. Some of them, termed glomerulopathic light chains, interact with the mesangial cells and trigger, in a manner dependent of their structural and physicochemical properties, a sequence of pathological events that results in either light chain–derived (AL) amyloidosis (AL-Am) or light chain deposition disease (LCDD). The mesangial cells play a key role in the pathogenesis of both diseases. The interaction with the pathogenic light chain elicits specific cellular processes, which include apoptosis, phenotype transformation, and secretion of extracellular matrix components and metalloproteinases. Monoclonal light chains associated with AL-Am but not those producing LCDD are avidly endocytosed by mesangial cells and delivered to the mature lysosomal compartment where amyloid fibrils are formed. Light chains from patients with LCDD exert their pathogenic signaling effect at the cell surface of mesangial cells. These events are generic mesangial responses to a variety of adverse stimuli, and they are similar to those characterizing other more frequent glomerulopathies responsible for many cases of end-stage renal disease. The pathophysiologic events that have been elucidated allow to propose future therapeutic approaches aimed at preventing, stopping, ameliorating, or reversing the adverse effects resulting from the interactions between glomerulopathic light chains and mesangium.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wound healing is an important area of research in contemporary medicine. Unani is a traditional medicine system based on hundreds of years of observations and experiences. Wounds are described under the headings qarha (arabic) and jarāhat (persian) in classical Unani texts. Several drugs of herbal, mineral and animal origin are described in Unani texts as having wound healing properties. Many of these drugs have been screened on various scientific parameters but the potential of most drugs remains unexplored. METHODOLOGY The study was aimed at summarizing the topical wound healing drugs mentioned in classical Unani books. The topical wound healing drugs were first identified in classical texts. Then 20 drugs were selected for detailed review on the basis of clinical relevance and wide availability. OBSERVATIONS AND RESULTS Seventy drugs were identified in Unani texts after removal of duplicacy. Most of the drugs (85.71%) were of herbal origin, while 10% were of mineral origin and the rest 4.28% were of animal origin. Most of the herbal drugs belonged to the Fabaceae (10%) and Rosaceae (8.33%) families. Biologically active compounds such as phenols, sterols, hydrocarbons, anthocyanidins, flavonoids and tannins have been identified in almost all drugs which support classical literature. CONCLUSION Unani system of medicine has a rich legacy of effective wound healing drugs, which is reinforced by modern researches. Most drugs exert their action on multiple phases of wound healing. In addition, most drugs have no reported adverse effects in laboratory and clinical studies. Hence, Unani medicine may offer the much-needed affordable and effective wound care in a wide range of clinical settings.

Abstract
Visible light-curable hydrogels have been investigated as tissue engineering scaffolds and drug delivery carriers due to their physicochemical and biological properties such as porosity, reservoirs for drugs/growth factors, and similarity to living tissue. The physical properties of hydrogels used in biomedical applications can be controlled by polymer concentration, cross-linking density, and light irradiation time. The aim of this review chapter is to outline the results of previous research on visible light-curable hydrogel systems. In the first section, we will introduce photo-initiators and mechanisms for visible light curing. In the next section, hydrogel applications as drug delivery carriers will be emphasized. Finally, cellular interactions and applications in tissue engineering will be discussed.

Abstract
Tuberculosis (TB), caused by the bacterial organism Mycobacterium tuberculosis, pose a major threat to public health, especially in middle and low-income countries. Worldwide in 2018, approximately 10 million new cases of TB were reported to the World Health Organization (WHO). There are a limited number of medications available to treat TB; additionally, multi-drug resistant TB and extensively-drug resistant TB strains are becoming more prevalent. As a result of various factors, such as increased costs of developing new medications and adverse side effects from current medications, researchers continue to evaluate natural compounds for additional treatment options. These substances have the potential to target bacterial cell structures and may contribute to successful treatment. For example, a study reported that green and black tea, which contains epigallocatechin gallate (a phenolic antioxidant), may decrease the risk of contracting TB in experimental subjects; cumin (a seed from the parsley plant) has been demonstrated to improve the bioavailability of rifampicin, an important anti-TB medication, and propolis (a natural substance produced by honeybees) has been shown to improve the binding affinity of anti-TB medications to bacterial cell structures. In this article, we review the opportunistic pathogen M. tuberculosis, various potential therapeutic targets, available therapies, and natural compounds that may have anti-TB properties. In conclusion, different natural compounds alone as well as in combination with already approved medication regimens should continue to be investigated as treatment options for TB.

Abstract
The emergence of new materials with improved antibacterial, anti-inflammatory and healing properties compared to conventional wound dressings has both social and economic appeal. In this study, novel chitosan-based (CTS) membranes containing curcumin (CUR) incorporated in Pluronic (PLU) copolymers were developed and characterized to obtain suitable properties for applications as a wound healing dressing. The mechanical, thermal, swelling, wettability, release and permeation properties were evaluated by DSC, TGA, water contact angle measurements, FTIR, fluorescence and microscopic techniques. Membranes containing PLU and CUR presented wettability close to the ideal range for interaction with cellular components (contact angle ~40-70°), improved mechanical properties, higher thermal stability, high swelling degree (>800%) and CUR release (~60%) compared to samples without PLU addition. A higher retention of CUR in the epidermis than in the dermis layer was observed, which also was confirmed by confocal microscopy. Furthermore, the CTS-PLU membranes loaded with CUR showed to be active against Staphylococcus aureus and Pseudomonas aeruginosa (MIC = 25 and 100 mg mL-1, respectively), the microbial species most present in chronic wounds. Overall, the CTS-PLU-CUR membranes presented suitable properties to act as a new wound healing dressing formulation and in vivo studies should be performed to confirm these benefits.

Abstract
Oxidative stress is a toxic cellular condition, strictly related to inflammation and known to be a common feature of many neurodegenerative diseases. The imbalanced redox state modifies several molecular processes including protein SUMOylation, JNK and Tau protein activation, important actors in Alzheimer's disease. In this study, we showed a strong interaction among SUMO-1-JNK-Tau proteins and their molecular targets in an in vitro model (SHSY5Y cell line) of oxidative stress in which a significant reduction of cell viability and an augmented cell death was induced by increased doses of H2O2. The evoked oxidative stress led to a deficiency in the degradation system showing altered levels of Caspase-3, LC3BII/I and Ubiquitin. Curcumin, a natural compound with anti-oxidant and anti-inflammatory effects, demonstrated to tackle oxidative stress re-equilibrating SUMO-1, JNK and Tau functions. Importantly, 5 μM of curcumin induced an efficient recovery of cell viability, a reduction of cell death and a normalization of altered protein degradation marker levels. Interestingly, we found that H2O2 treatment induced a strong co-localization of SUMO-1-p-JNK-Tau proteins in nuclear bodies (NBs) and that curcumin was able to reduce these nuclear aggregates. These results highlight the SUMO-1-JNK-Tau axis key role in oxidative stress and the protective effect of curcumin against this pathological event, focusing on the importance of SUMO/deSUMOylation balance to regulate essential cellular processes.

Abstract
Wound management is a major contributor towards the economic burden placed upon the national health service (NHS), serving as an important target for the development of advanced therapeutic interventions. The economic expenditure of wound care for the NHS exceeds £5 billion per annum, thus presenting a significant opportunity for the introduction of alternative treatments in regards to their approach in tackling the ever increasing prevalence of wound management associated problems. As most wounds typically fall under the acute or chronic category, it is therefore necessary to design a therapeutic intervention capable of effectively resolving the pathologies associated with each problem. Such an intervention should be of increased economic viability and therapeutic effectiveness when compared to standardized treatments, thus helping to alleviate the financial burden imposed upon the NHS. The purpose of this review is to critically analyse the various aspects associated with wound management, detailing the fundamental concepts of dermal regeneration, whilst also providing an evaluation of the different materials and methods that can be utilised to achieve maximal wound regeneration. The primary aspects of this review revolve around the three concepts of antibacterial methodology, enhancement of dermal regeneration and the utilisation of a carrier medium to facilitate the regenerative process. Each aspect is explored, conveying its justifications as a target for dermal regeneration, whilst offering various solutions towards the fulfilment of a therapeutic design that is both effective and financially feasible.

Abstract
Curcuma longa is an important medicinal plant and a spice in Asia. Curcumin (diferuloylmethane) is a hydrophobic bioactive ingredient found in a rhizome of the C. longa. It has drawn immense attention in recent years for its variety of biological and pharmacological action. However, its low water solubility, poor bioavailability, and rapid metabolism represent major drawbacks for its successful therapeutic applications. Hence, researchers have attempted to enhance the biological and pharmacological activity of curcumin and overcome its drawbacks by efficient delivery systems, particularly nanoencapsulation. Research efforts so far and data from the available literature have shown a satisfactory potential of nanorange formulations of curcumin (Nanocurcumin), it increases all the biological and pharmacological benefits of curcumin, which was not significantly possible earlier. For the synthesis of nanocurcumin, an array of techniques has been developed and each technique has its own advantages and individual characteristics. The two most popular and effective techniques are ionic gelation and antisolvent precipitation. So far, many curcumin nanoformulations have been developed to enhance curcumin delivery, thereby overcoming the low therapeutic effects. However, most of the nanoformulation of curcumin remained at the concept level evidence, thus, several questions and challenges still exist to recommend the nanocurcumin as a promising candidate for therapeutic applications. In this review, we discuss the different curcumin nanoformulation and nanocurcumin implications for different therapeutic applications as well as the status of ongoing clinical trials and patents. We also discuss the research gap and future research directions needed to propose curcumin as a promising therapeutic candidate.

Abstract
Chronic wounds are a remarkable cause of morbidity, requiring long-time treatments with a significant impact on the quality of life and high costs for public health. Although there are a variety of topical skin preparations commercially available, they have several limitations that frequently impair wound healing, such as drug instability, toxicity, limited time of action and ineffective skin permeation. In recent years, researchers have focused on the development of new effective treatments for wound healing and shown frequent interest in nanometric drug delivery systems to overcome such obstacles. In dermatology, lipid nanoparticles (LNPs) have received great attention from researchers due to their great functionalities, greater adhesion to the skin and film formation, enabling the hydration and maintenance of skin integrity, as well as present a more effective penetration through the skin barrier. This review provides an update on topical formulations based on Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs) as wound healing treatments. Both SLNs and NLCs are able to increase solubility and stability of active pharmaceutical ingredients and increase skin penetration compared to the free drugs. Additionally, SLNs and NLCs can increase pharmacological activity, increase the release profile of the drugs, promote synergistic effects and improve the sensory properties of the final formulation. Topical dosage forms containing nanoparticles have been extensively evaluated for wound healing activity, mainly the dressings, films and scaffolds. Therefore, lipid nanoparticles have contributed in improving wound healing therapies when incorporated into other dosage forms with better efficacy and lesser adverse effects than conventional formulations.

Abstract
Natural products have been used in medicine for thousands of years. Given their potential health benefits, they have gained significant popularity in recent times. The administration of phytochemicals existed shown to regulate differential gene expression and modulate various cellular pathways implicated in cell protection. Curcumin is a natural dietary polyphenol extracted from Curcuma Longa Linn with different biological and pharmacological effects. One of the important targets of curcumin is Toll-like receptor-4 (TLR-4), the receptor which plays a key role in the modulation of the immune responses and the stimulation of inflammatory chemokines and cytokines production. Different studies have demonstrated that curcumin attenuates inflammatory response via TLR-4 acting directly on receptor, or by its downstream pathway. Curcumin bioavailability is low, so the use of exosomes, as nano drug delivery, could improve the efficacy of curcumin in inflammatory diseases. The focus of this review is to explore the therapeutic effect of curcumin interacting with TLR-4 receptor and how this modulation could improve the prognosis of neuroinflammatory and rheumatic diseases.

Abstract
Curcumin grafted hyaluronic acid modified pullulan polymers (Cur-HA-SPu) by chemical conjugation was designed and prepared, and its film may be used to accelerate wound healing and help to fight infection. The synthesis of Cur-HA-SPu polymer was characterized by FT-IR, 1H NMR and DSC. Cur-HA-SPu film has a higher swelling ratio than that of HA-SPu film. Moreover, the good biocompatibility of Cur-HA-SPu polymer was confirmed by skin irritation, cytotoxicity and hemolysis tests. Compared to Cur, the MTT and proliferation test carried out in L929 cells revealed that Cur-HA-SPu polymer showed no cytotoxicity and enhanced cell proliferation. Cur-HA-SPu polymer exhibited a certain bactericidal activity against E. coli and S. aureus. Furthermore, the materials showed antioxidant activity when DPPH method determined. Wound healing study using wistar rat model demonstrated that Cur-HA-SPu film obtained better wound healing result than that of HA-SPu film or natural healing. The above results suggest that Cur-HA-SPu film is a promising and safety formulation for accelerating skin wound healing.

Abstract
Cutaneous wound healing is one of the public health interests. This study aimed to investigate the effects of nanoemulsion cream containing lavender essential oil and licorice extract on the healing of deep skin wound in a rat model. Eighty-five male Wistar rats were randomly divided into five groups including untreated defects as negative control and defects treated with vehicle ointment, lavender essential oil and licorice extract in emulsion and nanoemulsion forms, and phenytoin 1% as the positive control with an excisional wound on the dorsal neck of each rat. On days 2, 7 and 14 oxidative stress factors were evaluated in wound tissue homogenates. The expression of transforming growth factor-β (TGF-β), and type I and type III collagen genes were evaluated. Also, wound tissue samples were processed for Hematoxylin & Eosin and Masson-Trichrome staining. Nanoemulsion reduced the wound area more than other groups significantly. Real-time PCR data demonstrated that nanoemulsion and phenytoin groups have shown the best result in increasing TGF-β1, Type I and type III collagen genes expression compared to the other groups. Reduction in lipid peroxidation level and increasing in SOD and GPx activity was also significant in the nanoemulsion and phenytoin groups. The formation of granular tissue likewise the appearance of collagen in nanoemulsion and phenytoin groups were faster than the other groups. Nanoemulsion cream containing lavender essential oil and licorice extract exhibited a promising wound healing potential towards the excisional wound model in rats.

Abstract
Surfactants are important ingredients in pharmaceutical and cosmetic formulations, as in creams, shampoos or shower gels. As conventional emulsifiers such as sodium dodecyl sulfate (SDS) have fallen into disrepute due to their skin irritation potential, the naturally occurring lecithins are being investigated as a potential alternative. Thus, lecithin-based nanoemulsions with and without the drug curcumin, known for its wound healing properties, were produced and characterised in terms of their particle size, polydispersity index (PDI) and zeta potential and compared to SDS-based formulations. In vitro toxicity of the produced blank nanoemulsions was assessed with primary human keratinocytes and fibroblasts using two different cell viability assays (BrdU and EZ4U). Further, we investigated the penetration profiles of the deployed surfactants and oil components using combined ATR-FTIR/tape stripping experiments and confirmed the ability of the lecithin-based nanoemulsions to deliver curcumin into the stratum corneum in tape stripping-UV/Vis experiments. All manufactured nanoemulsions showed droplet sizes under 250 nm with satisfying PDI and zeta potential values. Viability assays with human skin cells clearly indicated that lecithin-based nanoemulsions were superior to SDS-based formulations. ATR-FTIR tests showed that lecithin and oil components remained in the superficial layers of the stratum corneum, suggesting a low risk for skin irritation. Ex vivo tape stripping experiments revealed that the kind of oil used in the nanoemulsion seemed to influence the depth of curcumin penetration into the stratum corneum.

Abstract
Fabricating and designing a scaffold is a complex and highly challenging process in the current scenario. The present study deals with the design and fabrication of electrospun Santa Barbara Amorphous (SBA)-15-incorporated polyvinyl alcohol (PVA) with curcumin, which can be used as a biomimetic nanoscaffold for skin tissue engineering. Curcumin was selected due to its effective anti-microbial and anti-inflammatory properties. SBA-15 was selected for its characteristic drug-carrying potential. Fourier transform infrared spectroscopy and x-ray diffraction characterizations of the fabricated nanofiber demonstrated the interaction of PVA, SBA-15 and curcumin. The scanning electron microscopy results depicted that the nanofiber was highly interconnected with a porous structure mimicking the extracellular matrix. The nanofibrous scaffold showed a higher percentage of cell migration, proliferation, cytocompatibility and biocompatibility with absence of cytotoxicity which was evidenced from the results of MTT assay, cell adhesion and live/dead assay using HaCaT cells. The results of the anti-bacterial test depicted that the synthesized nanofiber forms a potent material for skin wound-healing therapeutics. The in vitro drug release study performed over a period of 80 h revealed a sustained release pattern of curcumin from the SBA-15-incorporated PVA nanofiber. Finally, the in vivo results confirmed that SBA-15-incorporated PVA nanofiber with curcumin showed efficient wound-healing activities.

Abstract
In this study, nanofibrous scaffolds were prepared from polyurethane and cellulose acetate using electrospinning. Reduced graphene oxide/silver nanocomposites, rGO/Ag, were also used into the mats due to the strong antibacterial activity of rGO/Ag nanocomposites. In order to prevent the agglomeration of silver nanoparticles, AgNPs, the nanoparticles were decorated onto the reduced graphene oxide (rGO) sheets. Initially, Graphene oxide, briefly GO, was synthesized by the improved Hummer method. Then, nanocomposites of reduced graphene oxide were decorated with Ag and were fabricated via a green and facile hydrothermal method. Thereafter, the scaffold containing rGO/Ag nanocomposites, curcumin or both of them were prepared using the electrospinning method. The obtained scaffolds were characterized by scanning electron microscopy (SEM), contact angle, tensile analysis, porosity, and water vapor transmission rate (WVTR). 3-[4,5-Dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide assay, MTT, confirmed the biocompatibility of the composite nanofibers. The scaffolds were able to hinder both of the Gram-negative and Gram-positive bacteria through direct contact with them. In vivo histopathological studies indicated that the scaffold incorporated rGO/Ag nanocomposites and curcumin has the most effect on wound healing and can promote the healing rate of artificial wounds, which indicates the good biomedical potential of nanomaterial in wound healing.

Abstract
Diabetic wound characterizes with a delayed repair as a result of the lack of neoangiogenesis and the excess of inflammation. Natural products such as curcumin have shown great promises in their regulatory potentials on inflammation and angiogenesis. However, natural agents have several shortages in their bioavailability and stability when used in vivo. In this study, we have evaluated the efficacy of a topical formulation of curcumin in the enhancement of diabetic wound repair. Streptozocin-induced diabetic mice were wounded, and cream of curcumin (1%) was applied topically to wounds twice daily for different treatment periods. Inflammation, neoangiogenesis, and re-epithelialization were evaluated in each experimental group. Wounds of animals treated with curcumin showed an enhanced neoangiogenesis. Application of topical curcumin also increased the expression level of RelA as the main subunit of the nuclear factor-κB (NF-κB) signalling pathway. However, no significant effects on macrophage polarization and re-epithelialization were observed in the curcumin-treated animals. Our study using a higher concentration of curcumin in the form of a topical cream further confirmed the efficacy of curcumin as an angiogenesis-promoting agent; however, it also conveyed uncertainty over the claimed regulatory effects of curcumin on inflammation. SIGNIFICANCE OF THE STUDY: Diabetes results in several complications such as impaired cutaneous wound repair. Excess of inflammation and lack of angiogenesis are among the main causes of delayed healing in diabetes. Curcumin is famous for its anti-inflammatory properties. However, when in the body curcumin has shown to have a limited benefit unless in high-dosage consumes. This is because of its poor absorption from digestive system and its bioavailability. In this study, we have used a topical formulation of curcumin at a relatively high concentration to enhance the healing of a diabetic wound in an animal model of diabetes. We also have studied different cellular and molecular mechanisms by which curcumin may help the wound repair. Our results re-emphasize the proangiogenic potential of curcumin in diabetic wound environment.

Abstract
OBJECTIVES The aim of this study was to investigate the molecular mechanisms of the efficacy of lignin compound dehydrodiconiferyl alcohol (DHCA) isolated from Silybum marianum (L.) Gaertn in improving wound healing. These findings preliminarily brought to light the promising therapeutic potential of DHCA in skin wound healing. METHODS First, the effect of DHCA on healing in vivo was studied using a full-thickness scalp wound model of mice by topical administration. Histopathological examinations were then conducted by haematoxylin and eosin (H&E), Masson's trichrome staining and the immunofluorescence assay. Second, we further examined the anti-inflammatory mechanism of DHCA in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages by immunofluorescence assay and Western blot analysis. KEY FINDINGS DHCA could promote scalp wound healing in mice by enhancing epithelial cell proliferation and collagen formation and reducing inflammatory cells infiltration. Moreover, the NF-κB nuclear translocation was suppressed remarkably by DHCA administration in connective tissue of healing area. DHCA was also shown to inhibit production of nitric oxide (NO) and interleukin (IL)-1β with downregulated inducible nitric oxide synthase (iNOS) expression in LPS-induced RAW 246.7 cells. More importantly, DHCA administration upregulated p-IκBα expression and induced nuclear translocation of NF-κB without affecting its expression. CONCLUSIONS Our study indicated that DHCA exerted anti-inflammatory activity through inactivation of NF-κB pathways in macrophages and subsequently improved wound healing.

Abstract
![]()
Chronic wounds are
often recalcitrant to treatment because of high
microbial bioburden and the problem of microbial resistance. Silver
is a broad-spectrum natural antimicrobial agent with wide applications
extending to proprietary wound dressings. Recently, silver nanoparticles
have attracted attention in wound management. In the current study,
the green synthesis of nanoparticles was accomplished using a natural
reducing agent, curcumin, which is a natural polyphenolic compound
that is well-known as a wound-healing agent. The hydrophobicity of
curcumin was overcome by its microencapsulation in cyclodextrins.
This study demonstrates the production, characterization of silver
nanoparticles using aqueous curcumin:hydroxypropyl-β-cyclodextrin
complex and loading them into bacterial cellulose hydrogel with moist
wound-healing properties. These silver nanoparticle-loaded bacterial
cellulose hydrogels were characterized for wound-management applications.
In addition to high cytocompatibility, these novel dressings exhibited
antimicrobial activity against three common wound-infecting pathogenic
microbes Staphylococcus aureus, Pseudomonas
aeruginosa, and Candida auris.

Photodiagnosis Photodyn Ther 2020; 30:101674. [PMID: 31996322 DOI: 10.1016/j.pdpdt.2020.101674] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Revised: 01/14/2020] [Accepted: 01/24/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Potential complications during fixed orthodontic procedures are white spot lesions (WSLs) and tooth decay. This study evaluated the anti-biofilm activity of an orthodontic adhesive (OA) incorporating curcumin (Cur) doped Poly lactic-co-glycolic acid nanoparticles (Cur-PLGA-NPs), which can have the highest concentration of Cur-PLGA-NPs and shear bond strength (SBS) value simultaneously, against cariogenic bacteria i.e., Streptococcus mutans. MATERIALS AND METHODS Following synthesis and confirmation of Cur-PLGA-NPs, SBS and adhesive remnant index (ARI) of the modified orthodontic adhesives (MOA) containing Cur-PLGA-NPs (3, 5, 7, and 10 % wt.) were measured using universal testing machine and stereomicroscope, respectively. After artificial aging (continuously rinsed up to 180 days), the residual anti-biofilm ability of MOA which can have the highest concentration of Cur-PLGA-NPs and SBS value simultaneously were determined by anti-biofilm assay following photoexcited enamel slab bonded brackets by MOA containing Cur-PLGA-NPs against S. mutans biofilms using crystal violet assay. RESULTS Adhesive with 7 % wt. Cur-PLGA-NPs revealed the highest concentration of Cur-PLGA-NPs and SBS value (16.19 ± 2.69 MPa, P < 0.05) simultaneously. No statistically significant difference in ARI scores was observed between the MOA and control (Transbond XT without the Cur-PLGA-NPs). On days 15, 30, 60, 90 and 120 there was a considerable decrease in optical density (OD) of preformed S. mutans biofilms on photoexcited enamel slab bonded brackets using MOA containing 7 % wt. Cur-PLGA-NPs, to 94.1 %, 79.6 %, 69.6 %, 69.4 %, and, 55.1 % respectively in comparison to the control group (all, P < 0.05). From days 150 onwards, microbial biofilm formation was progressively increased on enamel slab bonded brackets using MOA containing 7 % wt. Cur-PLGA-NPs compared to the control group (OA). Although chlorhexidine (2 %; as positive control) showed significant activity against pre-formed S. mutans biofilms on enamel slab bonded brackets using OA (99.1 % biofilm reduction; P = 0.001), its activity was slightly higher but not significant than photoexcited enamel slab bonded brackets using MOA containing 7 % wt. Cur-PLGA-NPs on the days 15 and 30 (both, P > 0.05). CONCLUSIONS The 7 % wt. Cur-PLGA-NPs can serve as an orthodontic adhesive antimicrobial additive as exposure to blue laser provides an acceptable antimicrobial effect against cariogenic bacteria for a considerable time.

Abstract
BACKGROUND Curcumin likely has wound-healing properties, but its poor pharmacokinetic attributes inhibit its potential. To overcome these limitations, a novel nanoformulation was previously developed, wherein curcumin was loaded into mesoporous silica particles. OBJECTIVES The objective of the study is to assess the efficiency of this nanocurcumin formulation as a wound-healing agent in an animal model. MATERIALS AND METHODS Curcumin was loaded onto mesoporous silica particles. Eighteen healthy, test-naive male Wistar rats were randomly separated into two groups of 9: Group 1 (control) rats were treated topically with a standard drug (sulfadiazine) and Group 2 with 1% curcumin formulation. A circular excision wound was made, and topical application was performed twice a day. The excision diameters were measured on days 3, 6, 9, 12, 15, 18 and 21 of treatment. Three rats from each group were sacrificed on days 7, 14 and 21, and a cross-section from skin specimen in the excision injury was obtained for histological assessment of inflammation, angiogenesis, fibroblast proliferation, presence of collagen and reepithelization. RESULTS Wound contraction percentage in rats treated with curcumin nanoformulation was nonsignificantly higher than that in the control group (P > 0.05). In both groups, inflammatory reactions considerably reduced by day 21 of treatment, the angiogenesis process was almost complete by day 7, fibroblast proliferation noticeably rose by day 14, and a high degree of wound reepithelization was achieved by day 21, with no significant differences between the groups. Interestingly, by day 21, the level of collagen significantly increased in curcumin nanoformulation-treated rats compared with those treated with sulfadiazine. CONCLUSIONS Curcumin nanoformulation likely enhanced wound repair by inhibiting the inflammatory response, stimulating angiogenesis, inducing fibroblast proliferation as well as enhancing reepithelization and synthesis of collagen. Therefore, the curcumin nanoformulation used in this study may have potential as a wound-healing ethnomedicine.

Iron chelation by curcumin suppresses both curcumin-induced autophagy and cell death together with iron overload neoplastic transformation. Cell Death Discov 2019; 5:150. [PMID: 31839992 PMCID: PMC6901436 DOI: 10.1038/s41420-019-0234-y] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 10/24/2019] [Accepted: 11/11/2019] [Indexed: 12/13/2022] Open
Abstract
Iron overload, notably caused by hereditary hemochromatosis, is an excess storage of iron in various organs that causes tissue damage and may promote tumorigenesis. To manage that disorder, free iron depletion can be induced by iron chelators like deferoxamine that are of increasing interest also in the cancer field since iron stock could be a potent target for managing tumorigenesis. Curcumin, a well-known active substance extracted from the turmeric rhizome, destabilizes endoplasmic reticulum, and secondarily lysosomes, thereby increasing mitophagy/autophagy and subsequent apoptosis. Recent findings show that cells treated with curcumin also exhibit a decrease in ferritin, which is consistent with its chemical structure and iron chelating activity. Here we investigated how curcumin influences the intracellular effects of iron overload via Fe-nitriloacetic acid or ferric ammonium citrate loading in Huh-7 cells and explored the consequences in terms of antioxidant activity, autophagy, and apoptotic signal transduction. In experiments with T51B and RL-34 epithelial cells, we have found evidence that curcumin-iron complexation abolishes both curcumin-induced autophagy and apoptosis, together with the tumorigenic action of iron overload.

Polymers (Basel) 2019; 11:E1801.

Abstract
Periodontitis treatment is usually focused on the reduction or eradication of periodontal pathogens using antibiotics against anaerobic bacteria, such as metronidazole (MTR). Moreover, recently the correlation between periodontal diseases and overexpression of reactive oxygen species (ROS) led to the introduction of antioxidant biomolecules in therapy. In this work, bioadhesive buccal tablets, consisting of a hydrophilic matrix loaded with metronidazole and lipophilic nanoparticles as a vehicle of curcumin, were developed. Curcumin (CUR)-loaded nanostructured lipid carriers (NLC) were prepared using glycyrrhetic acid, hexadecanol, isopropyl palmitate and Tween®80 as a surfactant. As method, homogenization followed by high-frequency sonication was used. After dialysis, CUR-NLC dispersion was evaluated in terms of drug loading (DL, 2.2% w/w) and drug recovery (DR, 88% w/w). NLC, characterized by dynamic light scattering and scanning electron microscopy (SEM), exhibited a spherical shape, an average particle size of 121.6 nm and PDI and PZ values considered optimal for a colloidal nanoparticle dispersion indicating good stability of the system. Subsequently, a hydrophilic sponge was obtained by lyophilization of a gel based on trehalose, Natrosol and PVP-K90, loaded with CUR-NLC and MTR. By compression of the sponge, matrix tablets were obtained and characterized in term of porosity, swelling index, mucoadhesion and drugs release. The ability of the matrix tablets to release CUR and MTR when applied on buccal mucosa and the aptitude of actives to penetrate and/or permeate the tissue were evaluated. The data demonstrate the ability of NLC to promote the penetration of CUR into the lipophilic domains of the mucosal membrane, while MTR can penetrate and permeate the mucosal tissue, where it can perform a loco-regional antibacterial activity. These results strongly support the possibility of using this novel matrix tablet for delivering MTR together with CUR for topical treatment of periodontal diseases.
