Abstract
In this report, eco-friendly synthesis for the production of copper nanoparticles by employing the sodium lignosulfonate (NaLS) mixed starch composite (NaLS-Starch/Cu NPs). NaLS-Starch mixed hydrogel has notable reducing and stabilizing potential for preparation of Cu nanoparticles. Characterization of NaLS-Starch/Cu NPs bionanocomposite was subjected to analysis of spectroscopic and microscopic techniques, including FE-SEM, TEM, EDS-elemental mapping, particle size distribution, XRD and ICP. TEM images displayed the spherical structured NaLS-Starch/Cu NPs, averaging 5-10 nm size. NaLS-Starch/Cu NPs were applied to cure the induced burn wounds in 60 Wistar rats. A group was considered as control group. The animals were treated with basal, tetracycline 3 % and NaLS-Starch/Cu NPs 3 % for 30 days and the treatment efficacy was determined according to the burn wound area reduction and molecular and histological characteristics. Taken together, these results support therapeutic use of NaLS-Starch/Cu NPs as potent ointment that may be proposed for burn wound healing. NaLS-Starch/Cu NPs ointment increased the levels of platelet-derived growth factors (PDGF) and fibroblast growth factor (bFGF). The mean wound surface, in all groups treated by NaLS-Starch/Cu NPs was larger than control group.

Abstract
Chronic wound healing is a common clinical challenge, characterized by bacterial infection, protracted inflammatory response, oxidative stress, and insufficient neovascularization. Nanozymes have emerged as a promising solution for treating skin wounds due to their antioxidant, antibacterial, and angiogenic properties. In recent years, combining nanozymes with hydrogels to jointly promote wound healing has attracted increasing research interest. However, most of the current nanocomposite hydrogels are still not effective in simultaneously controlling inflammatory, oxidative stress and bacterial invasion in wound healing. Improving the therapeutic functional diversity and efficacy of nanocomposite hydrogels remains a problem that needs to be addressed. In this study, we prepared nanocomposite hydrogels (GelMD-Cur@ZHMCe) by combining methylacrylated gelatin modified with dopamine (GelMD) with Zinc-doped hollow mesoporous cerium oxide nanoparticles loaded with curcumin (Cur@ZHMCe). The resulting hydrogels exhibited excellent water absorption, adhesion, and biocompatibility. In vitro and in vivo studies have demonstrated that GelMD-Cur@ZHMCe has excellent antioxidant, antibacterial, anti-inflammatory and vasculature-promoting properties, which enable it to rapidly promote wound repair. The wound healing rate of the rat total skin defect infection model treated with GelMD-Cur@ZHMCe reached 98.5±4.9 % after 14 days of treatment. It was demonstrated that this multifunctional nanocomposite hydrogel provides a promising therapeutic strategy for skin repair.

Charkiewicz AE. Is Copper Still Safe for Us? What Do We Know and What Are the Latest Literature Statements? Curr Issues Mol Biol 2024; 46:8441-8463. [PMID: 39194715 DOI: 10.3390/cimb46080498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Revised: 07/29/2024] [Accepted: 07/31/2024] [Indexed: 08/29/2024] Open
Abstract
Copper (Cu) is a precious metal and one of the three most abundant trace elements in the body (50-120 mg). It is involved in a large number of cellular mechanisms and pathways and is an essential cofactor in the function of cellular enzymes. Both its excess and deficiency may be harmful for many diseases. Even small changes in Cu concentration may be associated with significant toxicity. Consequently, it can be damaging to any organ or tissue in our body, beginning with harmful effects already at the molecular level and then affecting the degradation of individual tissues/organs and the slow development of many diseases, such as those of the immunological system, skeletal system, circulatory system, nervous system, digestive system, respiratory system, reproductive system, and skin. The main purpose of this article is to review the literature with regard to both the healthiness and toxicity of copper to the human body. A secondary objective is to show its widespread use and sources, including in food and common materials in contact with humans. Its biological half-life from diet is estimated to range from 13 to 33 days. The retention or bioavailability of copper from the diet is influenced by several factors, such as age, amount and form of copper in the diet, lifestyle, and genetic background. The upper limit of normal in serum in healthy adults is approximately 1.5 mg Cu/L, while the safe upper limit of average intake is set at 10-12 mg/day, the reference limit at 0.9 mg/day, and the minimum limit at 0.6-0.7 mg/day. Cu is essential, and in the optimal dose, it provides antioxidant defense, while its deficiency reduces the body's ability to cope with oxidative stress. The development of civilization and the constant, widespread use of Cu in all electrical devices will not be stopped, but the health of people directly related to its extraction, production, or distribution can be controlled, and the inhabitants of nearby towns can be protected. It is extremely difficult to assess the effects of copper on the human body because of its ubiquity and the increasing reports in the literature about its effects, including copper nanoparticles.

A gelatin methacryloyl (GelMA) treated with gallic acid and coated with specially designed nanoparticles derived from ginseng enhances the healing of wounds in diabetic rats. Int J Biol Macromol 2024; 274:133372.

Abstract
Due to persistent inflammation and oxidative stress reactions, achieving drug absorption in diabetic wounds is challenging. To overcome this problem, our article presents a composite hydrogel, GelMA-GA/DMOG@GDNP, which consists of gelatin methacryloyl (GelMA) treated with gallic acid (GA) and encapsulating ginseng-derived nanoparticles (GDNPs) loaded with dimethyloxallyl glycine (DMOG). The composite hydrogel demonstrates excellent biocompatibility. In laboratory settings, the hydrogel inhibits the production of nitric oxide synthase 2 (iNOS) in mouse immune cells (RAW264.7 cells), enhances the growth and migration of mouse connective tissue cells (L929 cells) and human endothelial cells (HUVECs), and promotes tube formation in HUVECs. In a rat model of type 1 diabetes-induced wounds, the composite hydrogel attenuates inflammatory reactions, facilitates the formation of fibres and blood vessels, accelerates wound healing, and elucidates specific pathway mechanisms through transcriptome sequencing. Therefore, the GelMA-GA/DMOG@GDNP hydrogel can serve as a safe and efficient wound dressing to regulate the inflammatory response, promote collagen fiber and blood vessel formation, and accelerate wound healing. These findings suggest that utilizing this multifunctional engineered nanoparticle-loaded hydrogel in a clinical setting may be a promising strategy for diabetic wound healing.

[PMID: 39204335 PMCID: PMC11360739 DOI: 10.3390/pharmaceutics16080990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 07/12/2024] [Accepted: 07/22/2024] [Indexed: 09/04/2024] Open
Abstract
Wound healing progresses through three distinct stages: inflammation, proliferation, and remodeling. Immune regulation is a central component throughout, crucial for orchestrating inflammatory responses, facilitating tissue repair, and restraining scar tissue formation. Elements such as mitochondria, reactive oxygen species (ROS), macrophages, autophagy, ferroptosis, and cytokines collaboratively shape immune regulation in this healing process. Skin wound dressings, recognized for their ability to augment biomaterials' immunomodulatory characteristics via antimicrobial, antioxidative, pro- or anti-inflammatory, and tissue-regenerative capacities, have garnered heightened attention. Notwithstanding, a lack of comprehensive research addressing how these dressings attain immunomodulatory properties and the mechanisms thereof persists. Hence, this paper pioneers a systematic review of biomaterials, emphasizing immune regulation and their underlying immunological mechanisms. It begins by highlighting the importance of immune regulation in wound healing and the peculiarities and obstacles faced in skin injury recovery. This segment explores the impact of wound metabolism, infections, systemic illnesses, and local immobilization on the immune response during healing. Subsequently, the review examines a spectrum of biomaterials utilized in skin wound therapy, including hydrogels, aerogels, electrospun nanofiber membranes, collagen scaffolds, microneedles, sponges, and 3D-printed constructs. It elaborates on the immunomodulatory approaches employed by these materials, focusing on mitochondrial and ROS modulation, autophagic processes, ferroptosis, macrophage modulation, and the influence of cytokines on wound healing. Acknowledging the challenge of antibiotic resistance, the paper also summarizes promising plant-based alternatives for biomaterial integration, including curcumin. In its concluding sections, the review charts recent advancements and prospects in biomaterials that accelerate skin wound healing via immune modulation. This includes exploring mitochondrial transplantation materials, biomaterial morphology optimization, metal ion incorporation, electrostimulation-enabled immune response control, and the benefits of composite materials in immune-regulatory wound dressings. The ultimate objective is to establish a theoretical foundation and guide future investigations in the realm of skin wound healing and related materials science disciplines.

Abstract
Deep vein thrombosis (DVT) is a venous return disorder caused by abnormal clotting of blood in deep veins. After thrombosis, most of the thrombus will spread to the deep vein trunk throughout the limb. If DVT is not treated in time, most of them will develop into thrombosis sequelae and even threaten life. Intravenous thrombolytic drugs are the most promising strategy for treating DVT, but current drugs used for thrombolysis suffer from short half-lives and narrow therapeutic indexes. To effectively manage DVT, it is necessary to develop a novel multifunctional drug-loading system to effectively prolong the treatment time and improve the therapeutic efficacy. In this study, a urokinase-loaded protocatechuic aldehyde-modified chitosan microsphere drug-loading platform was constructed for the treatment of DVT. This microsphere adsorbed urokinase well through electrostatic interaction, and the introduction of bovine serum albumin conferred stability to the microspheres. Therefore, the microsphere drug delivery system could achieve slow drug release to effectively dissolve blood fibrin. In addition, chitosan grafted with protocatechuic aldehyde imparted excellent antioxidant activity to the system to reduce free radicals in the blood vessels. Effective management of oxidative stress could avoid abnormal platelet activation and new thrombus formation. The experimental results showed that this microsphere had good biocompatibility, anti-inflammatory properties, and considerable thrombolytic activity. In conclusion, this study provided a new direction and developed a novel multi-functional nano microsphere drug delivery platform for the treatment of DVT.

Abstract
Microbial infections based on drug-resistant pathogenic organisms following surgery or trauma and uncontrolled bleeding are the main causes of increased mortality from trauma worldwide. The prevalence of drug-resistant pathogens has led to a significant increase in medical costs and poses a great threat to the normal life of people. This is an important issue in the field of biomedicine, and the emergence of new antimicrobial materials hydrogels holds great promise for solving this problem. Hydrogel is an important material with good biocompatibility, water absorption, oxygen permeability, adhesion, degradation, self-healing, corrosion resistance, and controlled release of drugs as well as structural diversity. Bacteria-disturbing hydrogels have important applications in the direction of surgical treatment, wound dressing, medical device coating, and tissue engineering. This paper reviews the classification of antimicrobial hydrogels, the current status of research, and the potential of antimicrobial hydrogels for one application in biomedicine, and analyzes the current research of hydrogels in biomedical applications from five aspects: metal-loaded hydrogels, drug-loaded hydrogels, carbon-material-loaded hydrogels, hydrogels with fixed antimicrobial activity and biological antimicrobial hydrogels, and provides an outlook on the high antimicrobial activity, biodegradability, biocompatibility, injectability, clinical applicability and future development prospects of hydrogels in this field.

Abstract
INTRODUCTION Copper oxide nanoparticles (CuONPs) have emerged as potential antibacterial agents. In this study, we aimed to synthesize CuONPs using Terminalia chebula (T. chebula) dried fruit extract and evaluate their antibacterial activity against specific wound pathogens. Our primary objective was to comprehensively characterize dried T. chebula fruit (TCF)-CuONPs and assess their antibacterial efficacy. METHODS CuONPs were synthesized through a green synthesis approach employing T. chebula dried fruit extract. Structural and compositional characterization involved UV-visible spectroscopy, scanning electron microscopy (SEM), elemental dispersive X-ray analysis (EDX), and transmission electron microscopy (TEM). The antibacterial activity of CuONPs was assessed against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli through various assays, including agar well diffusion, time-kill curve, protein leakage analysis, and antibiofilm assays. RESULTS Characterization revealed a distinct absorption peak at 440 nm in UV-visible spectroscopy, spherical morphology under SEM, and the presence of copper in EDX analysis. TEM revealed nanoparticle dimensions of approximately 10-12 nm. In antibacterial assays, TCF-CuONPs displayed significant efficacy, with Pseudomonas aeruginosa exhibiting heightened susceptibility. CONCLUSION This study successfully synthesized eco-friendly copper oxide nanoparticles using T. chebula dried fruit extract and thoroughly characterized their structural and compositional attributes. CuONPs exhibited substantial antibacterial potency against specific wound pathogens, indicating their potential in wound management applications. These findings contribute to the development of sustainable antibacterial solutions with implications for healthcare and environmental sustainability. Further research can delve into the mechanisms and broader applications of CuONPs based on the specific experimental outcomes.
