Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition characterized by persistent inflammation and oxidative stress, which ultimately leads to progressive restriction of airflow. Extensive research findings have cogently suggested that the dysregulation of essential transition metal ions, notably iron, copper, and zinc, stands as a critical nexus in the perpetuation of inflammatory processes and oxidative damage within the lungs of COPD patients. Unraveling the intricate interplay between metal homeostasis, oxidative stress, and inflammatory signaling is of paramount importance in unraveling the intricacies of COPD pathogenesis. This comprehensive review aims to examine the current literature on the sources, regulation, and mechanisms by which metal dyshomeostasis contributes to COPD progression. We specifically focus on iron, copper, and zinc, given their well-characterized roles in orchestrating cytokine production, immune cell function, antioxidant depletion, and matrix remodeling. Despite the limited number of clinical trials investigating metal modulation in COPD, the advent of emerging methodologies tailored to monitor metal fluxes and gauge responses to chelation and supplementation hold great promise in unlocking the potential of metal-based interventions. We conclude that targeted restoration of metal homeostasis represents a promising frontier for ameliorating pathological processes driving COPD progression.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) and Wilson's disease (WD) are both systemic diseases that can affect multiple organs in the body. The coexistence of SLE and WD is rarely encountered in clinical practice, making it challenging to diagnose. CASE REPORT We present the case of a 9-year-old girl who initially presented with proteinuria, haematuria, pancytopenia, hypocomplementemia, and positivity for multiple autoantibodies. She was diagnosed with SLE, and her blood biochemistry showed elevated liver enzymes at the time of diagnosis. Despite effective control of her symptoms, her liver enzymes remained elevated during regular follow-up. Laboratory tests revealed decreased serum copper and ceruloplasmin levels, along with elevated urinary copper. Liver biopsy revealed chronic active hepatitis, moderate inflammation, moderate-severe fibrosis, and a trend towards local cirrhosis. Genetic sequencing revealed compound heterozygous mutations in the ATP7B gene, confirming the diagnosis of SLE with WD. The girl received treatment with a high-zinc/low-copper diet, but her liver function did not improve. Upon recommendation following multidisciplinary consultation, she underwent liver transplantation. Unfortunately, she passed away on the fourth day after the surgery. CONCLUSIONS SLE and WD are diseases that involve multiple systems and organs in the body, and SLE complicated with WD is rarely encountered in the clinic; therefore, it is easy to misdiagnose. Because penicillamine can induce lupus, it is not recommended. Liver transplantation is indicated for patients with liver disease who do not respond to medical treatment with WD. However, further research is needed to determine the optimal timing of liver transplantation for patients with SLE complicated with WD.

Abstract
Both chemodynamic therapy and photodynamic therapy, based on the production of reactive oxygen (ROS), have excellent potential in cancer therapy. However, the abnormal redox homeostasis in tumor cells, especially the overexpressed glutathione (GSH) could scavenge ROS and reduce the anti-tumor efficiency. Therefore, it is essential to develop a simple and effective tumor-specific drug delivery system for modulating the tumor microenvironment (TME) and achieving synergistic therapy at the tumor site. In this study, self-assembled nanoparticles (named CDZP NPs) were developed using copper ion (Cu2+), doxorubicin (Dox), zinc phthalocyanine (ZnPc) and a trace amount of poly(2-(di-methylamino)ethylmethacrylate)-poly[(R)-3-hydroxybutyrate]-poly(2-(dimethylamino)ethylmethacrylate) (PDMAEMA-PHB-PDMAEMA) through chelation, π-π stacking and hydrophobic interaction. These triple factor-responsive (pH, laser and GSH) nanoparticles demonstrated unique advantages through the synergistic effect. Highly controllable drug release ensured its effectiveness at the tumor site, Dox-induced chemotherapy and ZnPc-mediated fluorescence (FL) imaging exhibited the distribution of nanoparticles. Meanwhile, Cu2+-mediated GSH-consumption not only reduced the intracellular ROS elimination but also produced Cu+ to catalyze hydrogen peroxide (H2O2) and generated hydroxyl radicals (˙OH), thereby enhancing the chemodynamic and photodynamic therapy. Herein, this study provides a green and relatively simple method for preparing multifunctional nanoparticles that can effectively modulate the TME and improve synergetic cancer therapy.

Abstract
The ancient anti-alcohol drug disulfiram (DSF) has gained widespread attention for its highly effective anti-tumor effects in cancer treatment. Our previous studies have developed liposome of Cu (DDC)2 to overcome the limitations, like the poor water solubility. However, Cu (DDC)2 liposomes still have shown difficulties in severe hemolytic reactions at high doses and systemic toxicity, which have limited their clinical use. Therefore, this study aims to exploratively investigate the feasibility of using DSF or DDC in combination also can chelate Zn2+ to form zinc diethyldithiocarbamate (Zn (DDC)2). Furthermore, this study prepared stable and homogeneous Zn (DDC)2 liposomes, which were able to be released in the tumor microenvironment (TME). The released Zn (DDC)2 was converted to Cu (DDC)2 with the help of endogenous Cu2+-switch enriched in the TME, which has a higher stability constant compared with Zn (DDC)2. In other words, the Cu2+-switch is activated at the tumor site, completing the conversion of the less cytotoxic Zn (DDC)2 to the more cytotoxic Cu (DDC)2 for effective tumor therapy so that the Zn (DDC)2 liposomes in vivo achieved the comparable therapeutic efficacy and provided a safer alternative to Cu (DDC)2 liposomes in cancer therapy.

Abstract
The therapeutic efficacy of cuproptosis combined with phototheranostics is still hindered by easy copper efflux, nonspecific accumulation and limited light penetration depth. Here, a high-performance NIR-II semiconductor polymer was first synthesized through dual-donor engineering. Then a biomimetic cuproptosis amplifier (PCD@CM) was prepared by Cu(II)-mediated coordinative self-assembly of NIR-II ultrasmall polymer dots and the chemotherapeutic drug DOX, followed by camouflaging of tumor cell membranes. After homologous targeting delivery to tumor cells, overexpressed GSH in the tumor microenvironment (TME) triggers the disassembly of the amplifier and the release of therapeutic components through the reduction of Cu(II) to Cu(I), which enable NIR-II fluorescence/photoacoustic imaging-guided NIR-II photothermal therapy (PTT) and chemotherapy. The released Cu(I) induces the aggregation of lipoylated mitochondrial proteins accompanied by the loss of iron-sulfur proteins, leading to severe proteotoxic stress and eventually cuproptosis. NIR-II PTT and GSH depletion render tumor cells more sensitive to cuproptosis. The amplified cuproptosis sensitization provokes significant immune surveillance, triggering the immunogenic cell death (ICD) to promote cytotoxic T lymphocyte infiltration together with aPD-L1-mediated immune checkpoint blockade. This work proposes a new strategy to develop cuproptosis sensitization systems enhanced by NIR-II phototheranostics with homologous targeting and anti-tumor immune response capabilities.

Abstract
Malignant tumors are still one of the most deadly diseases that threaten human life and health. However, developing new drugs is challenging due to lengthy trials, funding constraints, and regulatory approval procedures. Consequently, researchers have devoted themselves to transforming some clinically approved old drugs into antitumor drugs with certain active ingredients, which have become an attractive alternative. Disulfiram (DSF), an antialcohol medication, can rapidly metabolize in the physiological environment into diethyldithiocarbamate (DTC) which can readily react with Cu2+ ions in situ to form the highly toxic bis(N,N-diethyldithiocarbamate)-copper(II) (CuET) complex. In this study, DSF is loaded into mesoporous dopamine nanocarriers and surface-chelated with tannin and Cu2+ to construct M-MDTC nanoprodrugs under the camouflage of K7 tumor cell membranes. After intravenous injection, M-MDTC nanoprodrugs successfully reach the tumor sites with the help of mediated cell membranes. Under slightly acidic pH and photothermal stimulation conditions, DSF and Cu2+ are simultaneously released, forming a highly toxic CuET to kill tumor cells in situ. The generated CuET can also induce immunogenic cell death of tumor cells, increase the proportion of CD86+ CD80+ cells, and promote dendritic cell maturation. In vitro and in vivo studies of M-MDTC nanoprodrugs have shown excellent tumor-cell-killing ability and solid tumor suppression. This approach enables in situ amplification of chemotherapy in the tumor microenvironment, achieving an effective antitumor treatment.

Abstract
Sharply rising oxidative stress and ineffectual angiogenesis have imposed restrictions on diabetic wound healing. Here, a photothermal-responsive nanodelivery platform (HHC) was prepared by peroxidase (CAT)-loaded hollow copper sulfide dispersed in photocurable methacrylamide hyaluronan. The HHC could scavenge reactive oxygen species (ROS) and promote angiogenesis by photothermally driven CAT and Cu2+ release. Under near-infrared light irradiation, the HHC presented safe photothermal performance (<43 °C), efficient bacteriostatic ability against E. coli and S. aureus. It could rapidly release CAT into the external environment for decomposing H2O2 and oxygen generation to alleviate oxidative stress while promoting fibroblast migration and VEGF protein expression of endothelial cells by reducing intracellular ROS levels. The nanodelivery platform presented satisfactory therapeutic effects on murine diabetic wound healing by modulating tissue inflammation, promoting collagen deposition and increasing vascularization in the neodermis. This HHC provided a viable strategy for diabetic wound dressing design.

Abstract
Triple negative breast cancer (TNBC) is a subtype of breast cancer which is characterized by its aggressiveness, poor and short overall survival. In this concept, there is a growing demand for metal-based compounds in TNBC therapy as copper complex that have a less toxic effect on normal cells and could stimulate apoptotic cell death. Additionally, Notch1 signaling pathway has received great attention as one of the most important potential targets for developing a novel therapeutic strategy. The present study is an attempt to assess the promising chemotherapeutic activities of copper(I) nicotinate (CNC) through its impact on the expression of downstream genes of Notch1 signaling pathway and the cell fate of TNBC. The co-treatment of TNBC cells with doxorubicin (Doxo) and CNC was also investigated. To approach the objective of the present study, TNBC cell lines; HCC1806 and MDAMB231, were utilized. MTT assay was used to determine the IC50 values of CNC and Doxo. After treatment, microtubule-associated protein light chain3 (LC3) were determined by flow cytometry. Additionally, qRT-PCR technique was used to detect the changes in genes levels that are involved Notch1 signaling pathway. Moreover, autophagosomes were monitored and imaged by Transmission electron microscopy. Treatment of TNBC cells with CNC modulated Notch1 signaling pathway in different manners with respect to the type of cells and the applied dose of CNC. The observed effects of CNC may reflect the possible anti-cancer activities of CNC in both types of TNBC. However, cell type and CNC dose should be considered.

Abstract
INTRODUCTION Stevens-Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN) are severe adverse drug reactions characterized by widespread blistering and mucositis. Wilson's disease is a rare, autosomal recessive disorder that results in excessive copper accumulation in the body, where penicillamine is an effective treatment option for copper chelation. Penicillamineinduced SJS-TEN is a rare but potentially fatal adverse effect. There is increased susceptibility to SJS/TEN in HIV infection due to immunosuppression and chronic liver disease due to impaired hepatic function. OBJECTIVE To diagnose and manage the occurrence of the rare severe adverse cutaneous drug reactions in the backdrop of immunosuppression and chronic liver disease. CASE REPORT We are reporting penicillamine-induced SJS-TEN overlap in a 30-year-old male with Wilson's disease, HIV and Hepatitis B who was treated with intravenous immunoglobulins. The patient later developed neurotrophic ulcer in the right cornea as a delayed sequela. CONCLUSION Our case report emphasizes that there is an increased predisposition to SJS/TEN in immunocompromised and chronic liver disease patients. Physicians should be well aware of the potential danger of SJS/TEN in this subset of patients, even while prescribing a relatively safer drug.

Abstract
In recent years, with the continuous in-depth exploration of the molecular mechanisms of tumorigenesis, numerous potential new targets for cancer treatment have been identified, some of which have been further developed in clinical practice and have produced positive outcomes. Notably, researchers' initial motivation for studying copper metabolism in cancer stems from the fact that copper is a necessary trace element for organisms and is closely connected to body growth and metabolism. Moreover, over the past few decades, considerable progress has been made in understanding the molecular processes and correlations between copper and cancer. Certain achievements have been made in the development and use of relevant clinical medications. The concept of "cuproptosis," a novel concept that differs from previous forms of cell death, was first proposed by a group of scientists last year, offering fresh perspectives on the targeting capabilities of copper in the treatment of cancer. In this review, we introduced the fundamental physiological functions of copper, the key components of copper metabolism, and a summary of the current research contributions on the connection between copper and cancer. In addition, the development of new copper-based nanomaterials and their associated mechanisms of action are discussed. Finally, we described how the susceptibility of cancer cells to this metallic nutrition could be leveraged to further improve the existing cancer treatment paradigm in the new setting.

Abstract
Wound infections and delayed complications after caesarean section surgical procedure to mothers would have a prevalence of discomfort, stress and dissatisfaction in the postpartum period. In this report, one-pot synthesis is used for the preparation of chitosan (CS)-based copper nanoparticles (nCu), which was used for the preparation of zinc oxide (ZnO) hydrogel as wound dressing materials after surgery. The antibacterial activity of (CS-nCu/ZnO) developed hydrogels was studied zone of inhibition, against gram-positive and gram-negative bacteria. The antibacterial activity of the CS-nCu/ZnO hydrogel demonstrated that nanoformulated hydrogel materials have provided excellent bactericidal action against clinically approved bacterial pathogens. The biocompatibility and in vitro wound healing potential of the developed wound closure materials were studied by MTT assay and wound scratch assay methods, respectively. The MTT assay and cell migration assay results demonstrated that CS-nCu/ZnO hydrogel material induces cell compatibility and effective cell proliferation ability. These findings suggest that the CS-nCu/ZnO hydrogel outperforms CS-ZnO in terms of wound healing and could be used as a wound closure material in caesarean section wound treatment.

Abstract
Photodynamic therapy (PDT) has been used to reduce cancerous and precancerous cells via reactive oxygen species (ROS) generation from photosensitizers. Numerous photosensitizers are available today to treat a variety of diseases, but their therapeutic efficacy is hindered within the tumor microenvironment, and there are safety concerns associated with their non-specific activation. In this work, we disclosed a nano-therapeutic based on in situ activatable nitrobenzene-cysteine-copper(II) nano-complexes (NCCNs) that work within cancer cells. Among the NCCNs, CyP shows outstanding potential as a promising candidate for programmed photodynamic cancer therapy with its unique properties such as (i) bright near-infrared imaging, (ii) chemodynamic therapeutic effect, (iii) photodynamic therapeutic effect (types I and II), and (iv) anti-cancer effect by anti-angiogenesis in early cancer stage under light. Overall, this work opens up exciting possibilities for the development of innovative and effective treatments for cancer, paving the way for future advancements in the clinical medicine field.

Abstract
OBJECTIVE The quest for an ideal wound dressing has been a longstanding challenge due to the complex nature of wound healing, including stages of haemostasis, inflammation, maturation and remodelling, with overlapping timelines. This makes it difficult to find a single dressing that optimally supports all phases of wound healing. In addition, the ideal wound dressing should possess antibacterial properties and be capable of effectively debriding and lysing necrotic tissue. Copper is an essential trace element that participates in many of the key physiological wound healing processes. METHOD Copper stimulates secretion of various cytokines and growth factors, thus promoting angiogenesis, granulation tissue formation, extracellular matrix proteins secretion and re-epithelialisation. Harnessing this knowledge, we have used copper oxide-impregnated wound dressings in numerous cases and observed their benefits throughout the entire wound healing process. RESULTS This led us to postulate the 'continuum of care' hypothesis of copper dressings. In this study we describe four cases of hard-to-heal wounds of various aetiologies, in which we applied copper dressings consistently across all stages of wound healing, with rapid uneventful healing. CONCLUSION We believe we have successfully implemented the continuum of care principle.

Abstract
BACKGROUND Footbaths can be used to manage digital dermatitis (DD), a common cause of lameness in dairy cattle. Copper sulfate and chelated copper-zinc (CZS) solutions in footbaths are potentially harmful to the environment. HYPOTHESIS/OBJECTIVES To determine if a quaternary ammonium salt-based disinfectant (QASD) footbath is as effective as a chelated CZS solution in controlling DD in dairy cows. ANIMALS Fifty-one lactating Holstein cows were randomly assigned to one of two treatment groups, with DD status based on the M-stage scoring system and locomotion score balanced between treatment groups. MATERIALS AND METHODS The groups were treated with a 1% QASD or a 2.5% chelated CZS. Footbaths were performed once per week for 15 weeks. Logistic regression was used to analyse clinical improvement. All cows received appropriate medical treatment for DD and other hoof diseases. RESULTS Clinical improvement rates were 67% in the QASD group and 38% in the CZS group (p = 0.03). Logistic regression analysis showed that the odds (95% confidence interval) for clinical improvement rate in the CZS group were 0.30 (0.095-0.948) times that of the QASD group (p = 0.04). The M0 score in the QASD and CZS groups increased significantly (p < 0.05) at the end of the 15 week study period. In the QASD group, the proportion of M2, M3 and M4 scores were significantly decreased (p < 0.05). CONCLUSION AND CLINICAL RELEVANCE Over a 15 week period, QASD for footbathing was associated with a lower prevalence of active DD lesions than when using CZS.

Abstract
Aim: To develop an optimized approach for encapsulating a 2-alkylthioimidazolone-based copper coordination compound within liposomes, which could offer treatment of cancer and bacterial infections by reactive oxygen species generation toxicity mechanisms. Materials & methods: For drug-loaded liposome preparation, lipids and drug mixture in organic solvents was injected into copper salt solution, forming a coordination compound simultaneously embedded in the lipid bilayer. In vitro tests were performed on MCF7 and MDA-MB-231 breast cancer cells. Results: Liposomes had a loading capacity of up to 1.75% (molar drug-to-lipid ratio). In vitro tests showed increased viability and accumulation of the liposomal formulation compared with free drug as well as lack of cytotoxicity in hepatocytes. Conclusion: This optimized technique for encapsulating large copper complexes in liposomes could be used to improve their delivery and better treat cancer and bacterial infections.

Abstract
BACKGROUND Copper homeostasis and cuproptosis play critical roles in various biological processes of cancer; however, whether they can impact the prognosis of lung adenocarcinoma (LUAD) remain to be fully elucidated. We aimed to adopt these concepts to create and validate a lncRNA signature for LUAD prognostic prediction. METHODS For this study, the TCGA-LUAD dataset was used as the training cohort, and multiple datasets from the GEO database were pooled as the validation cohort. Copper homeostasis and cuproptosis regulated genes were obtained from published studies, and various statistical methods, including Kaplan-Meier (KM), Cox, and LASSO, were used to train our gene signature CoCuLncSig. We utilized KM analysis, COX analysis, receiver operating characteristic analysis, time-dependent AUC analysis, principal component analysis, and nomogram predictor analysis in our validation process. We also compared CoCuLncSig with previous studies. We performed analyses using R software to evaluate CoCuLncSig's immunotherapeutic ability, focusing on eight immune algorithms, TMB, and TIDE. Additionally, we investigated potential drugs that could be effective in treating patients with high-risk scores. Additionally qRT-PCR examined the expression patterns of CoCuLncSig lncRNAs, and the ability of CoCuLncSig in pan-cancer was also assessed. RESULTS CoCuLncSig containing eight lncRNAs was trained and showed strong predictive ability in the validation cohort. Compared with previous similar studies, CoCuLncSig had more prognostic ability advantages. CoCuLncSig was closely related to the immune status of LUAD, and its tight relationship with checkpoints IL10, IL2, CD40LG, SELP, BTLA, and CD28 may be the key to its potential immunotherapeutic ability. For the high CoCuLncSig score population, we found 16 drug candidates, among which epothilone-b and gemcitabine may have the most potential. The pan-cancer analysis found that CoCuLncSig was a risk factor in multiple cancers. Additionally, we discovered that some of the CoCuLncSig lncRNAs could play crucial roles in specific cancer types. CONCLUSION The current study established a powerful prognostic CoCuLncSig signature for LUAD that was also valid for most pan-cancers. This signature could serve as a potential target for immunotherapy and might help the more efficient application of drugs to specific populations.

Abstract
Accurate targeting of therapeutic agents to specific tumor tissues, especially via deep tumor penetration, has been an effective strategy in cancer treatments. Here, we described a flexible nanoplatform, pH-responsive zwitterionic acylsulfonamide betaine-functionalized fourth-generation PAMAM dendrimers (G4-AB), which presented multiple advantages for chemo-photothermal therapy, including template synthesis of ultrasmall copper sulfide (CuS) nanoparticles and further encapsulation of doxorubicin (DOX) (G4-AB-DOX/CuS), long-circulating performance by a relatively large size and zwitterionic surface in a physiological environment, combined size shrinkage, and charge conversions via pH-responsive behavior in an acidic tumor microenvironment (TME). Accordingly, high tumor penetration and positive cell uptake for CuS and DOX have been determined, which triggered an excellent combination treatment under near-infrared irradiation in comparison to the monochemotherapy system and irresponsive chemo-photothermal system. Our study represented great promise in constructing multifunctional carriers for the effective delivery of photothermal nanoparticles and drugs in chemo-photothermal therapy.

Abstract
As the only Food and Drug Administration (FDA)-approved dual-encapsulation liposome injection for treating Acute myeloid leukemia (AML), CPX-351 outperforms the standard chemotherapy treatment "DA 7 + 3″ in terms of clinical effectiveness. Although research on dual-loaded liposomes has increased in recent years, little attention has been paid to their preparation, which can affect their quality, efficacy, and safety. This study explored various preparation processes to create the cytarabine/daunorubicin co-loaded liposome (the Cyt/Daun liposome) and eventually settled on two methods: the sequential loading approach, thin film hydration-extrusion-copper ion gradient, and the simultaneous encapsulation technique, copper ion gradient-concentration gradient. Different preparation methods resulted in different particle sizes and encapsulation efficiencies; the two aforementioned preparation processes generated dual-loaded liposomes with comparable physicochemical properties. The sequential encapsulation technique was selected for the subsequent research owing to its higher encapsulation efficiency prior to purification; the prepared Cyt/Daun liposomes had small and uniform particle size (108.6 ± 1.02 nm, Polydispersity index (PDI) 0.139 ± 0.01), negative charge (-(60.2 ± 1.15) mV), high drug encapsulation efficiency (Cyt 88.2 ± 0.24 %, Duan 94.2 ± 0.45 %) and good plasma stability. To improve its storage stability, the Cyt/Daun liposome was lyophilized (-40 °C for 4 h, maintained for 130 min, and dried for 1200 min) using sucrose-raffinose (mass ratio 7:3; glycolipid ratio 4:1, w/w) as a lyoprotectant. The lyophilized liposomes were purple cakes, redissolved rapidly with insignificant alterations in particle size and encapsulation efficiency, and possessed well storage stability. The pharmacokinetic and tissue distribution studies demonstrated that the Cyt/Daun liposome could achieve long circulation and maintain synergic proportions of drugs within 24 h, increasing the accumulation of drugs at tumor sites. Furthermore, the in vitro/in vivo pharmacodynamic studies confirmed its good anti-tumor activity and safety.

Abstract
BACKGROUND Huntington or Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterised by both progressive motor and cognitive dysfunction; its pathogenic mechanisms remain poorly understood and no treatment can currently slow, stop, or reverse its progression. There is some evidence of metallomic dysfunction in limited regions of the HD brain; we hypothesised that these alterations are more widespread than the current literature suggests and may contribute to pathogenesis in HD. METHODS We measured the concentrations of eight essential metals (sodium, potassium, magnesium, calcium, iron, zinc, copper, and manganese) and the metalloid selenium across 11 brain regions in nine genetically confirmed, clinically manifest cases of HD and nine controls using inductively-coupled plasma mass spectrometry. Case-control differences were assessed by non-parametric Mann-Whitney U test (p < 0.05), risk ratios, E-values, and effect sizes. FINDINGS We observed striking decreases in selenium levels in 11 out of 11 investigated brain regions in HD, with risk ratios and effect sizes ranging 2.3-9.0 and 0.7-1.9, respectively. Increased sodium/potassium ratios were observed in every region (risk ratio = 2.5-8.0; effect size = 1.2-5.8) except the substantia nigra (risk ratio = 0.25; effect size = 0.1). Multiple regions showed increased calcium and/or zinc levels, and localised decreases in iron, copper, and manganese were present in the globus pallidus, cerebellum, and substantia nigra, respectively. INTERPRETATION The observed metallomic alterations in the HD brain may contribute to several pathogenic mechanisms, including mitochondrial dysfunction, oxidative stress, and blood-brain barrier dysfunction. Selenium supplementation may represent a potential, much-needed therapeutic pathway for the treatment of HD that would not require localised delivery in the brain due to the widespread presence of selenium deficiency in regions that show both high and low levels of neurodegeneration.

Abstract
Copper is an essential trace element that is required for the activity of many enzymes and cellular processes, including energy homeostasis and neurotransmitter biosynthesis; however, excess copper accumulation results in significant cellular toxicity. The liver is the major organ for maintaining copper homeostasis. Inactivating mutations of the copper-transporting P-type ATPase, ATP7B, result in Wilson's disease, an autosomal recessive disorder that requires life-long medicinal therapy or liver transplantation. Current treatment protocols are limited to either sequestration of copper via chelation or reduction of copper absorption in the gut (zinc therapy). The goal of these strategies is to reduce free copper, redox stress, and cellular toxicity. Several lines of evidence in Wilson's disease animal models and patients have revealed altered hepatic metabolism and impaired hepatic nuclear receptor activity. Nuclear receptors are transcription factors that coordinate hepatic metabolism in normal and diseased livers, and several hepatic nuclear receptors have decreased activity in Wilson's disease and Atp7b-/- models. In this review, we summarize the basic physiology that underlies Wilson's disease pathology, Wilson's disease animal models, and the possibility of targeting nuclear receptor activity in Wilson's disease patients.

Abstract
Trace elements and metals play critical roles in the normal functioning of the central nervous system (CNS), and their dysregulation has been implicated in neurodegenerative disorders such as Alzheimer's disease (AD) and Parkinson's disease (PD). In a healthy CNS, zinc, copper, iron, and manganese play vital roles as enzyme cofactors, supporting neurotransmission, cellular metabolism, and antioxidant defense. Imbalances in these trace elements can lead to oxidative stress, protein aggregation, and mitochondrial dysfunction, thereby contributing to neurodegeneration. In AD, copper and zinc imbalances are associated with amyloid-beta and tau pathology, impacting cognitive function. PD involves the disruption of iron and manganese levels, leading to oxidative damage and neuronal loss. Toxic metals, like lead and cadmium, impair synaptic transmission and exacerbate neuroinflammation, impacting CNS health. The role of aluminum in AD neurofibrillary tangle formation has also been noted. Understanding the roles of these elements in CNS health and disease might offer potential therapeutic targets for neurodegenerative disorders. The Codex Alimentarius standards concerning the mentioned metals in foods may be one of the key legal contributions to safeguarding public health. Further research is needed to fully comprehend these complex mechanisms and develop effective interventions.

Abstract
Copper (Cu) is an essential element that is involved in a variety of biochemical processes. Both deficiency and accumulation of Cu are associated with various diseases; and a high amount of accumulated Cu in cells can be fatal. The production of reactive oxygen species (ROS), oxidative stress, and cuproptosis are among the proposed mechanisms of copper toxicity at high concentrations. Elesclomol (ELC) is a mitochondrion-targeting agent discovered for the treatment of solid tumors. In this review, we summarize the synthesis of this drug, its mechanisms of action, and the current status of its applications in the treatment of various diseases such as cancer, tuberculosis, SARS-CoV-2 infection, and other copper-associated disorders. We also provide some detailed information about future directions to improve its clinical performance.

Abstract
The employment of metal-organic framework (MOF)-based nanomaterials has been rapidly increasing in bioapplications owing to their biocompatibility, drug degradation, tunable porosity, and intrinsic biodegradability. This evidence suggests that the multifunctional bimetallic ions can behave as remarkable candidates for infection control and wound healing. In this study, bimetallic MOFs (Zn-HKUST-1 and FolA-Zn-HKUST-1) embedded with and without folic acid were synthesized and used for tissue sealing and repairing incisional wound sites in mice models. For comparison, HKUST-1 and FolA-HKUST-1 were also synthesized. The Brunauer-Emmett-Teller (BET) surface area measured for HKUST-1, FolA-HKUST-1, Zn-HKUST-1, and FolA-Zn-HKUST-1 from N2 isotherms was found to be 1868, 1392, 1706, and 1179 m2/g, respectively. The measurements of contact angle values for Zn-HKUST-1, FolA-HKUST-1, and Zn-FolA-HKUST-1 were identified as 4.95 ± 0.8, 43.6 ± 3.4, and 60.62 ± 2.0°, respectively. For topical application in wound healing, they display a wide range of healing characteristics, including antibacterial and enhanced wound healing rates. In addition, in vitro cell migration and tubulogenic potentials were evaluated. The significant reduction in the wound gap and increased expression levels for CD31, eNOS, VEGF-A, and Ki67 were observed from immunohistological analyses to predict the angiogenesis behavior at the incision wound site. The wound healing rate was analyzed in the excisional dermal wounds of diabetic mice model in vivo. On account of antibacterial potentials and tissue-repairing characteristics of Cu2+ and Zn2+ ions, designing an innovative mixed metal ion-based biomaterial has wide applicability and is expected to modulate the growth of various gradient tissues.

Abstract
Polycystic ovary syndrome (PCOS) is a multifactorial disorder with unknown etiology. The purpose of this systematic review is to analyze the available clinical trials on elemental supplementation in terms of improving biochemical parameters in women with PCOS. Electronic databases were searched from their inception until February 2023. Randomized controlled trials (RCTs) of PCOS during therapy with elemental supplementation alone or in combination with other elements were analyzed. Recommendations regarding supplementation with elements are not clear. There are many factors to consider, with the primary factor being the type of element and the possibility of supplementation and a balanced diet. Another aspect to consider is the presence of comorbidities, which may increase the demand for and absorption of elements. A final factor to be considered is the determination of the body's need for specific elements. Some elements may require supplementation (e.g., magnesium, selenium, iodine, calcium), while others (e.g., iron, copper, potassium, zinc, manganese, chromium) are in sufficient amounts in a proper diet, and some should be limited (e.g., sodium, phosphorus). It is necessary to determine the optimal dose of each element in order to improve the biochemical parameters of PCOS as much as possible, while at the same time avoiding the negative effects of excessive consumption.

Abstract
A novel chiral oxazoline copper(II)-based complex {[Cu(C13H14NO3S)2]}2 (Cu-A) was synthesized by an in situ reaction using L-methioninol, 4-hydroxyisophthalaldehyde, sodium hydroxide and copper(II) nitrate trihydrate as reactants. Its crystal structure was characterized. In vitro, Cu-A was superior to cis-dichlorodiammineplatinum (DDP) in cytotoxicity and angiogenesis inhibition. Cu-A significantly induced apoptosis of ovarian cancer cells (SKOV3) and human umbilical vein endothelial cells (HUVECs), showing significant anti-ovarian cancer and anti-angiogenesis effects. Notably, Cu-A significantly inhibits the growth of ovarian cancer in nude mice xenografted with SKOV3 cells, and it is less renal toxic than DDP. The molecular mechanism of anti-ovarian cancer and anti-angiogenesis is possibly that it down-regulates the expression of the proteins ERK1/2, AKT, FAK, and VEGFR2 and their phosphorylated proteins p-ERK1/2, p-AKT, p-FAK, and p-VEGFR2 in the VEGF/VEGFR2 signal transduction pathway to inhibit SKOV3 cell and HUVEC proliferation, induce apoptosis, suppress migration and metastasis, and inhibit angiogenesis. What's more, Cu-A significantly inhibits ovarian tumor growth in vivo by inhibiting tumor cells from inducing vascular endothelial cells to form their own vasculature and by inhibiting the expression of the anti-apoptotic protein Bcl-2 and up-regulating the expression of the pro-apoptotic proteins Caspase-9 and Bax to induce apoptosis of tumor cells.

Abstract
Our previous research discovered that combining the PDA-PEG polymer with copper ions can selectively kill cancer cells. However, the precise mechanism by which this combination functions was not fully understood. This study revealed that the PDA-PEG polymer and copper ions form complementary PDA-PEG/copper (Poly/Cu) nanocomplexes by facilitating copper ion uptake and lysosomal escape. An in vitro study found that Poly/Cu killed 4T1 cells through a lysosome cell death pathway. Furthermore, Poly/Cu inhibited both the proteasome function and autophagy pathway and induced immunogenic cell death (ICD) in 4T1 cells. The Poly/Cu induced ICD coupled with the checkpoint blockade effect of the anti-PD-L1 antibody (aPD-L1) synergistically promoted immune cell penetration into the tumor mass. Benefiting from the tumor-targeting effect and cancer cell-selective killing effect of Poly/Cu complexes, the combinatory treatment of aPD-L1 and Poly/Cu effectively suppressed the progression of triple-negative breast cancer without inducing systemic side effects.

Abstract
INTRODUCTION Wilson's disease (WD) is a copper metabolism disorder characterised by a progressive accumulation of this metal mainly in the liver and the brain. Treatment is based on the removal of copper operated by the chelators, among which, D-penicillamine (DP) is prescribed as a first-line treatment in most situations. There is some evidence in linking the use of DP with a risk of vitamin B6; therefore, vitamin supplementation is sometimes recommended, although non-consensually. The objective of our study was to evaluate the level of vitamin B6 in WD patients treated with DP with and without associated supplementation. METHODOLOGY All WD patients followed at the National Reference Centre for WD in Lyon between January 2019 and December 2020 treated with DP for more than 1 year were included and separated in two groups according to vitamin B6 supplementation. The level of vitamin B6 was measured by the determination of pyridoxal phosphate (PLP). RESULTS A total of 37 patients were included. Average age of 23.3±14.8 years, 15 patients with <18 years. Median duration of treatment was 51 (55.8) months. 15 patients were under vitamin B6 supplementation and 22 had interrupted it for more than 1 year. The median PLP level was significantly higher in the group with supplementation, 137.2 (86.7) nmol/L vs 64.9 (30.8) nmol/(p<0.01). No patient had a PLP level<35 nmol/L. CONCLUSION Long-term stable WD patients under DP treatment probably do not need vitamin B6 supplementation.

Abstract
INTRODUCTION Wilson's disease (WD) is a potentially treatable, inherited disorder resulting from impaired copper metabolism. Pathological copper accumulation causes a range of symptoms, most commonly hepatic and a wide spectrum of neurological symptoms including tremor, dystonia, chorea, parkinsonism, dysphagia, dysarthria, gait and posture disturbances. To reduce copper overload, anti-copper drugs are used that improve liver function and neurological symptoms in up to 85% of patients. However, in some WD patients, treatment introduction leads to neurological deterioration, and in others, neurological symptoms persist with no improvement or improvement only after several years of treatment, severely affecting the patient's quality of life. AREAS COVERED This review appraises the evidence on various pharmacological and non-pharmacological therapies, neurosurgical procedures and liver transplantation for the management of neurological WD symptoms. The authors also discuss the neurological symptoms of WD, causes of deterioration and present symptomatic treatment options. EXPERT OPINION Based on case and series reports, current recommendations and expert opinion, WD treatment is focused mainly on drugs leading to negative copper body metabolism (chelators or zinc salts) and copper-restricted diet. Treatment of WD neurological symptoms should follow general recommendations of symptomatic treatment. Patients should be always considered individually, especially in the case of severe, disabling neurological symptoms.

Abstract
Copper-associated hepatitis in dogs results from elevated copper levels secondary to increased intake or decreased clearance. Treatment is through establishing a negative copper balance and can include chelation therapy. Traditionally, chelation therapy in dogs is uses D-penicillamine, which has been shown to have severe side effects in humans. Side effects have not been well-documented in dogs but can include nephrotoxicity and dermatologic reactions. This article is the first to report neutropenia in a dog secondary to chelation therapy using D-penicillamine. In this case, a complete blood (cell) count (CBC) collected before initiation of chelation therapy was normal and neutropenia was documented 4 mo after starting therapy. A cytologic examination of bone marrow confirmed a myeloid hypoplasia. Following discontinuation of D-penicillamine, the neutropenia resolved. Based on this case report, periodic CBC rechecks following the initiation of D-penicillamine chelation therapy are recommended to guide treatment decisions. Key clinical message: Dogs with confirmed copper-associated hepatitis should be treated cautiously with D-penicillamine for chelation therapy. D-penicillamine may adversely affect bone marrow, causing a leukopenia characterized by neutropenia. It is recommended that clinicians periodically monitor neutrophil counts while treating dogs with D-penicillamine.

Abstract
The first description of the in vivo visualization of somatostatin receptor-positive tumors in patients was based on the use of a radioiodine (123I) labelled somatostatin analogue (Krenning et al. 1989). In the years that followed an Indium-111 (111In) labelled somatostatin analogue, chelated with diethylenetriaminepentaacetic acid (DTPA), was successfully developed. Subsequently, 111In-OctreoScan was introduced worldwide. In the years to come 99mTc-Tektrotyde became commercially available with easy access. In the last decade, with the increasing use of positron emission tomography (PET) imaging, somatostatin analogues have been labelled with various positron-emitting isotopes, such as Gallium-68 (68Ga) and Copper-64 (64Cu) (Lewis et al. 1999, Schottelius et al. 2004, Gabriel et al. 2007) e.g 68Ga-DOTATOC, 68Ga-DOTATATE 68Ga-DOTANOC and 68Cu-DOTATATE. Scintigraphy with these investigational compounds display encouraging good imaging quality amd improved sensitivity in tumor site detection compared with SPECT scintigraphy. Also, other PET radiopharmaceuticals were developed, such as 18F-dihydroxy-phenyl-alanine (18F-DOPA) and 11C-labelled 5-hydroxytryptophan (11C-5-HTP) with encouraging results in terms of visualization of GEP-NETs (Koopmans et al. 2008). After the successful introduction of SRS in the diagnosis and staging of NETs, the next logical step was to increase the administered activity so that the radiopharmaceutical can induce tumor shrinkage in patients who had inoperable and/or metastasized NENs. Therefore, the first peptide receptor radionuclide therapy (PRRT) was performed with high administered activity of [111In-DTPA0] octreotide (Krenning et al. 1994a). To make significant advancements in the treatment of somatostatin receptor-positive metastatic disease, more efficient radiolabelled somatostatin analogues were developed with higher affinity to the somatostatin receptor. Treatment with radiolabelled peptides or PRRT is a promising new therapeutic option in the management of inoperable or metastasized NETs. Symptomatic control can be achieved with all 111In-, 90Y- and 177Lu-labelled somatostatin analogue-based PRRT. For objective response and long-lasting duration of response, 90Y-DOTATOC and 177Lu-DOTATATE are the most promising radiopharmaceuticals. Side effects of PRRT are few and mild, if adequate kidney protective measures are taken and dose-limits are respected. In a minority of patients, when SRS fails to identify neuroendocrine disease, MIBG scintigraphy and subsequent 131I-MBG therapy might be an alternative treatment option. Targeted alpha-particle therapy (TAT) has emerged as an alternative treatment option to beta emitters in PRRT. The use of alpha emitters for cancer therapy has two advantages over beta emitter PRRT. The short range of alpha particles of only a few cell diameters (<0.1mm) allows for selective ablation of the target cancer cells, while sparing the surrounding healthy tissue. In addition, the higher linear energy transfer (LET), when compared to conventional beta emitters, results in the formation of complex DNA double-strand and DNA cluster breaks, which ultimately lead to cell death.(Lassmann M et al. Ann ICRP. 2018) Putative radiopharmaceuticals that can be considered for metastatic NEN treatment include Actinium-225 (225Ac)-DOTATATE and Bismuth-213 (213Bi)-DOTATOC. There was evidence of partial response using both radiopharmaceutical agents without significant hematological, renal, or hepatotoxicity. Future studies should consider longer term, randomized controlled trials investigating the role of TAT, in particular, 225c-DOTATATE, in the treatment of metastatic NENs. Nuclear medicine plays a pivotal role in the imaging and treatment of neuroendocrine tumors (NETs). New techniques in somatostatin receptor imaging include the use of different radiolabelled somatostatin analogues with higher affinity and different affinity profiles to the somatostatin receptor subtypes. Considerable advances have been made in the imaging of NETs, but to find the ideal imaging method with increased sensitivity and better topographic localization of the primary and metastatic disease remains the ultimate goal of research.

Abstract
BACKGROUND Dysgeusia is a relatively early symptom of zinc deficiency, and zinc replacement is effective in treating dysgeusia. The administration of zinc acetate hydrate (ZAH) was approved in 2017 for patients with hypozincemia in Japan. This retrospective study was conducted to explore the efficacy and safety of ZAH administration in patients with hypozincemia-induced dysgeusia. METHODS Patients with hypozincemia-induced dysgeusia who visited our hospital from May 2013 to December 2019 were included in this study. ZAH (zinc content; 50 mg/day) was administered to 42 patients for 24 weeks. The taste test was performed using the filter paper disk method, and the total cognitive thresholds of the left and right chorda tympani regions were used. Changes in taste function, serum zinc and copper levels, and copper/zinc ratio were analyzed. A total of 28 patients who received polaprezinc (PPZ, zinc content; 34 mg/day) for 24 weeks, who were prescribed until ZAH was approved, were registered as controls. RESULTS Serum zinc levels at 12 and 24 weeks after ZAH or PPZ administration were higher than those before administration. These levels were significantly higher in the ZAH-treated group than in the PPZ-treated group. However, serum copper levels did not significantly change before and after administration. In the taste test, the taste thresholds for the acidity and salty at 12 and 24 weeks after ZAH administration were significantly decreased compared to before administration. In contrast, in the PPZ group, the taste thresholds for the acidity and salty were significantly decreased 24 weeks after administration. CONCLUSIONS ZAH (50 mg/day) administration was effective in improving the gustatory sensitivity of patients with dysgeusia and hypozincemia 12 weeks after administration without affecting the serum copper level. ZAH was also more effective than PPZ.

Abstract
Currently the only drug available to treat Chagas disease in Brazil is benznidazole (BZN). Therefore, there is an urgent need to discover and develop new anti- Trypanosoma cruzi candidates. In our continuous effort to enhance clinical antiparasitic drugs using synergistic strategy, BZN was coordinated to silver and copper ions to enhance its effectiveness to treat that illness. In this work, the syntheses of four novel metal-BZN complexes, [Ag(BZN)2]NO3·H2O (1), [CuCl2(BZN)(H2O)]·1/2CH3CN (2), [Ag(PPh3)2(BZN)2]NO3·H2O (3), and [Cu(PPh3)2(BNZ)2]NO3·2H2O (4), and their characterization using multiple analytical and spectroscopic techniques such as Infrared (FTIR), Nuclear Magnetic Resonance (1H, 13C, 31P), UV-Visible (UV-Vis), Electron Paramagnetic Resonance (EPR), conductivity and elemental analysis are described. IC50 (Half-maximal inhibitory concentration) values of Ag-BZN compounds are about five to ten times lower than benznidazole itself in both proliferation stages of the parasite (epimastigotes and amastigotes). The cytotoxicity of both compounds in human cells (fibroblasts and hepatocytes) are comparable to BZN, indicating that Ag-BZN complexes can be more selective than BZN.

Abstract
Diabetes mellitus is a metabolic disorder described by compromised insulin synthesis or resistance to insulin inside the human body. Diabetes is a persistent metabolic condition defined by elevated amounts of glucose in the bloodstream, resulting in a range of potential consequences. The main purpose of this study was to find out how biosynthesized copper oxide nanoparticles (CuONPs) affect the blood sugar levels of diabetic albino rats induced by streptozotocin (STZ). In the current study, CuONPs were successfully biosynthesized using Saccharomyes cervisiae using an eco-friendly method. Characterization results revealed that biosynthesized CuONPs appeared at 376 nm with a spherical shape with sizes ranging from 4 to 47.8 nm. Furthermore, results illustrated that administration of 0.5 and 5 mg/kg CuONP in diabetic rats showed a significant decrease in blood glucose levels accompanied by elevated insulin levels when compared to the diabetic control group; however, administration of 0.5 mg/kg is the best choice for diabetic management. Furthermore, it was found that the group treated with CuONPs exhibited a noteworthy elevation in the HDL-C level, along with a depletion in triglycerides, total cholesterol, LDL-C, and VLDL-cholesterol levels compared to the diabetic control group. This study found that administration of CuONPs reduced hyperglycemia and improved pancreatic function as well as dyslipidemia in diabetic rats exposed to STZ, suggesting their potential as a promising therapeutic agent for diabetes treatment.

Abstract
Activated fibroblast-like synovial (FLS) cells are regarded as an important target for rheumatoid arthritis (RA) treatment via starvation therapy mediated by glucose oxidase (GOx). However, the hypoxic RA-FLS environment greatly reduces the oxidation process of glucose and leads to a poor therapeutic effect of the GOx-based starvation therapy. In this work, we designed a hollow mesoporous copper sulfide nanoparticles (CuS NPs)-based smart GOx/atovaquone (ATO) codelivery system (named as V-HAGC) targeting RA-FLS cells to realize a O2-economized dual energy inhibition strategy to solve the limitation of GOx-based starvation therapy. V-HAGC armed with dual multi-stimuli-responsive "doorkeepers" can guard drugs intelligently. Once under the stimulation of photothermal and acidic conditions at the targeted area, the dual intelligent responsive "doors" would orderly open to realize the controllable release of drugs. Besides, the efficacy of V-HAGC would be much improved by the additional chemodynamic therapy (CDT) and photothermal therapy (PTT) stimulated by CuS NPs. Meanwhile, the upregulated H2O2 and acid levels by starvation therapy would promote the Fenton-like reaction of CuS NPs under O2-economized dual energy inhibition, which could enhance the PTT and CDT efficacy as well. In vitro and in vivo evaluations revealed V-HAGC with much improved efficacy of this combination therapy for RA. In general, the smart V-HAGC based on the O2-economized dual energy inhibition strategy combined with enhanced CDT and PTT has the potential to be an alternative methodology in the treatment of RA.

Abstract
Cancer treatments which include conventional chemotherapy have not proven very successful in curing human malignancies. The failures of these treatment modalities include inherent resistance, systemic toxicity and severe side effects. Out of 50% patients administrated to chemotherapy, only 5% survive. For these reasons, the identification of new drug designs and therapeutic strategies that could target cancer cells while leaving normal cells unaffected still continues to be a challenge. Despite advances that have led to the development of new therapies, treatment options are still limited for many types of cancers. This review provides an overview of platinum, copper and ruthenium metal based anticancer drugs in clinical trials and in vitro/in vivo studies. Presumably, copper and ruthenium complexes have greater potential than Pt(II) complexes, showing reduced toxicity, a new mechanism of action, a different spectrum of activity and the possibility of non-cross-resistance. We focus the discussion towards past, present and future aspects.

Abstract
Combinatorial therapies have garnered enormous interest from researchers in efficiently devastating malignant tumors through synergistic effects. To explore the combinatorial approach, multiple therapeutic agents are typically loaded in the delivery vehicles, controlling their release profiles and executing subsequent therapeutic purposes. Herein, we report the fabrication of core (silica)-shell (mesoporous silica nanoparticles, MSNs) architectures to deliver methylene blue (MB) and cupric doxorubicin (Dox) as model drugs for synergistic photodynamic therapy (PDT), chemotherapy, and chemodynamic therapy (CDT). MB, as the photosensitizer, is initially loaded and stabilized in the silica core for efficient singlet oxygen generation under light irradiation towards PDT. The most outside shell with imidazole silane-modified MSNs is immobilized with a chemotherapeutic agent of Dox molecules through the metal (Copper, Cu)-ligand coordination interactions, achieving the pH-sensitive release and triggering the production of intracellular hydrogen peroxide and subsequent Fenton-like reaction-assisted Cu-catalyzed free radicals for CDT. Further, the designed architectures are systematically characterized using various physicochemical characterization techniques and demonstrate the potent anti-cancer efficacy against skin melanoma. Together our results demonstrated that the MSNs-based core-shell nanoarchitectures have great potential as an effective strategy in synergistically ablating cancer through chemo-, chemodynamic, and photodynamic therapies.

Abstract
Many current chemodynamic therapy (CDT) strategies suffer from either low therapeutic efficiency or the deficiency of poor targeting. The low therapeutic efficiency is mainly ascribed to the intracellular antioxidant system and the inefficient Fenton reaction in the weakly acidic tumor microenvironment (TME). Herein, by exploitation of the diverse function and programmability of functional nucleic acid, aptamer-tethered nanotrains of DNA copper nanoclusters (aptNTDNA-CuNCs) were assembled to simultaneously achieve targeted recognition, loading, and delivery of CDT reagents into tumor cells without an external carrier. The intracellular hydrogen peroxide (H2O2) oxidized nanotrains of DNA-CuNCs to produce a lot of Cu2+ and Cu+ ions, which can generate reactive oxygen species (ROS) in the weakly acidic TME based on the pH-independent Fenton-like reaction of Cu+/H2O2. Meanwhile, the redox reaction between intracellular glutathione (GSH) and Cu2+ depleted GSH and generated Cu+ ions, which weakened the antioxidant ability of cancer cells and further enhanced the Fenton-like reaction of Cu+/H2O2, respectively. Thus, the cascade Fenton-like reaction and GSH depletion doubly improved the efficacy of CDT. The in vivo and in vitro study solidly confirmed that aptNTDNA-CuNCs have excellent antitumor efficacy and no cytotoxicity to healthy cells. Therefore, aptNTDNA-CuNCs can act as CDT reagents to achieve highly efficient, biocompatible, and targeted CDT.

Abstract
Nanoparticle flexibility is an important parameter in determining cell uptake and tumor accumulation, thus modulating therapeutic efficiency in cancer treatment. Herein, we successfully prepared CuS-embedded human serum albumin hollow nanocapsules (denoted CuS/HSA) by a hard-core-assisted layer-by-layer coating approach. This approach afforded CuS/HSA hollow nanocapsules with controllable shell thickness, tunable flexibility, uniform size (272.9 nm), a large hollow cavity, peroxidase-like activity, excellent photothermal conversion ability, and a high tetra-(4-aminophenyl) porphyrin (TAPP) loading capacity (27.3 wt%). The peroxidase-like activity of the CuS nanoparticles enabled them to overcome tumor hypoxia and augment the sonodynamic therapeutic (SDT) effects and photothermal conversion ability for photothermal therapy (PTT). In vitro experiments showed that the CuS/HSA-TAPP hollow nanocapsules efficiently induced cancer cell apoptosis under US irradiation and cancer cell ablation under laser irradiation, thus facilitating synergistic SDT and PTT. Importantly, the flexibility of the CuS/HSA hollow nanocapsules resulted in significantly enhanced cellular internalization and a longer mean residence time (131.3 h) than their solid counterparts (21.0 h). In a breast tumor model, the flexible CuS/HSA hollow nanocapsules exhibited high tumor accumulation of up to 27.1%. In vivo experiments demonstrated that the flexible CuS/HSA-TAPP hollow nanocapsules effectively eliminated breast tumors via the synergistic effect of SDT and PTT.

Abstract
Developing effective intelligent nanotheranostics is highly desirable for cancer treatment but remains challenging. In this study, an acidic tumor microenvironment-activated organosilica nanosystem, namely AD-Cu-DOX-HA, is straightforwardly constructed, which is composed of aggregation-induced emission (AIE)-active photosensitizer, copper ion-engineered aminosilica, direct coordination polymer of doxorubicin (DOX), and targeting component hyaluronic acid (HA). AD-Cu-DOX-HA is able to accurately distinguish cancer cells over normal cells; meanwhile, it simultaneously exhibits selective accumulation and copper ion-mediated rapid disassembly and turn-on fluorescence in tumor tissue, consequently achieving efficient tumor diagnosis and tumor-growth inhibition through fluorescence imaging-navigated synergetic photodynamic therapy, copper ion-mediated chemodynamic therapy, and DOX-enabled chemotherapy. This work thus brings fresh insight into the exploration of versatile theranostics and presents a momentous advance for potential clinical cancer treatment.

Abstract
BACKGROUND In preclinical models of prostate cancer (PC), disulfiram (DSF) reduced tumor growth only when co-administered with copper (Cu), and Cu uptake in tumors is partially regulated by androgen-receptor signaling. However, prior trials of DSF in PC used DSF as monotherapy. OBJECTIVE To assess the safety and efficacy of concurrent administration of DSF with Cu, we conducted a phase 1b clinical trial of patients with metastatic castration-resistant prostate cancer (mCRPC) receiving Cu with DSF. DESIGN, SETTING, AND PARTICIPANTS Patients with mCRPC were treated in two cohorts: mCRPC with nonliver/peritoneal metastases (A), and mCRPC with liver and/or peritoneal metastases (B). Baseline Cu avidity was measured by 64 CuCl2 PET scan. Intravenous (IV) CuCl2 was given weekly for three doses with oral daily DSF followed by daily oral Cu gluconate and DSF until disease progression. DSF and metabolite diethyldithiocarbamic acid methyl ester (Me-DDC) levels in plasma were measured. DSF and Me-DDC were then assessed for cytotoxicity in vitro. RESULTS We treated nine patients with mCRPC (six on cohort A and three on cohort B). Bone and nodal metastases showed differential and heterogeneous Cu uptake on 64 CuCl2 PET scans. No confirmed PSA declines or radiographic responses were observed. Median PFS was 2.8 months and median OS was 8.3 months. Common adverse events included fatigue and psychomotor depression; no Grade 4/5 AEs were observed. Me-DDC was measurable in all samples (LOQ = 0.512 ng/ml), whereas DSF was not (LOQ = 0.032 ng/ml, LOD = 0.01 ng/ml); Me-DDC was not cytotoxic in vitro. CONCLUSIONS Oral DSF is not an effective treatment for mCRPC due to rapid metabolism into an inactive metabolite, Me-DDC. This trial has stopped enrollment and further work is needed to identify a stable DSF formulation for treatment of mCRPC.

Abstract
Our current investigation comprises the synthesis and pharmacological impact of bromelain copper nanoparticles (BrCuNP) against diabetes mellitus (DM) and associated ischemia/reperfusion (I/R) - induced myocardial infarction. Bromelain is a proteolytic enzyme obtained from Ananas comosus L. Merr., which has blood platelet aggregation inhibiting and arterial thrombolytic potential. Moreover, copper is well-known to facilitate glucose metabolism and strengthen cardiac muscle and antioxidant activity; although, chronic or long-term exposure to high doses of copper may lead to copperiedus. To restrict these potential hazards, we synthesized herbal nano-formulation which convincingly indicated the improved primordial therapeutic potential of copper by reformulating the treatment carrier with bromelain, resulting in facile synthesis of BrCuNP. DM was induced by administration of double cycle repetitive dose of low dose streptozotocin (20 mg/kg, i.p.) in high-fat diet- fed animals. DM and associated myocardial I/R injury were estimated by increased serum levels of total cholesterol, low-density lipoprotein, very low-density lipoprotein, lactate dehydrogenase, creatine kinase myocardial band, cardiac troponin, thiobarbituric acid reactive substances, tumor necrosis factor α, interleukin 6, and reduced serum level of high-density lipoprotein and nitrite/nitrate concentration. However, treatment with BrCuNP ameliorates various serum biomarkers by approving cardioprotective potential against DM- and I/R-associated injury. Furthermore, upturn of histopathological changes were observed in cardiac tissue of BrCuNP-treated rats in comparison to disease models.

Abstract
Biofilms formed from the pathogenic bacteria that attach to the surfaces of biomedical devices and implantable materials result in various persistent and chronic bacterial infections, posing serious threats to human health. Compared to the elimination of matured biofilms, prevention of the formation of biofilms is expected to be a more effective way for the treatment of biofilm-associated infections. Herein, we develop a facile method for endowing diverse substrates with long-term antibiofilm property by deposition of a hybrid film composed of tannic acid/Cu ion (TA/Cu) complex and poly(ethylene glycol) (PEG). In this system, the TA/Cu complex acts as a multifunctional building block with three different roles: (i) as a versatile "glue" with universal adherent property for substrate modification, (ii) as a photothermal biocidal agent for bacterial elimination under irradiation of near-infrared (NIR) laser, and (iii) as a potent linker for immobilization of PEG with inherent antifouling property to inhibit adhesion and accumulation of bacteria. The resulted hybrid film shows negligible cytotoxicity and good histocompatibility and could prevent biofilm formation for at least 15 days in vitro and suppress bacterial infection in vivo, showing great potential for practical applications to solve the biofilm-associated problems of biomedical materials and devices.

Abstract
Wilson's disease (WD) is an autosomal recessive genetic disorder of copper metabolism leading to liver or brain injury due to accumulation of copper. Diagnosis is based on: clinical features, biochemical tests including plasma ceruloplasmin concentration, 24h urinary copper excretion, copper content in the liver, and molecular analysis. Pharmacological therapy comprises chelating agents (penicillamine, trientine) and zinc salts which seem to be very effective. Still, poor compliance is a major problem. Adolescents and patients with psychiatric disorders usually have problems with adherence to treatment. As transition is a vulnerable period transition ''training'' should start before the planned transfer, preferably already in early adolescence in cooperation between adult and pediatric clinics. Response to treatment is assessed based on physical examination, normal liver function tests and monitoring of copper metabolism markers. Liver transplantation has a well-defined role in Wilsonian acute hepatic failure according to the prognostic score. The long-term survival in WD patients seems to be very similar as for the general population if disease is early diagnosed and correctly treated. WD patients with a longer delay from diagnosis to therapy and who present with neurological and psychiatric symptoms have worse quality of life.

Abstract
Immunotherapy is currently an important adjuvant therapy for malignant tumors besides surgical treatment. However, the heterogeneity and low immunogenicity of the tumor are two main challenges of the immunotherapy. Here, we have constructed a nanoplatform (CP@mRBC-PpIX) to realize reversion of the tumor acidosis and hypoxia through alkali and oxygen generation triggered by tumor acidosis. By targeting tumor universal features other than endogenous biomarkers, it was found that CP@mRBC-PpIX could polarize tumor-associated macrophages to anti-tumor M1 phenotype macrophages to enhance tumor immune response. Furthermore, under regional light irradiation, the reactive oxygen species produced by photosensitizers located in CP@mRBC-PpIX could increase the immunogenicity of tumors, so that tumor changes from an immunosuppressive "cold tumor" to an immunogenic "hot tumor," thereby increasing the infiltration and response of T cells, further amplifying the effect of immunotherapy. This strategy circumvented the problem of tumor heterogeneity to realize a kind of broad-spectrum immunotherapy, which could effectively prevent tumor metastasis and recurrence.

Abstract
Chemodynamic therapy (CDT) that utilizes Fenton-type reactions to convert endogenous hydrogen peroxide (H2O2) into hydroxyl radicals (•OH) is a promising strategy in anticancer treatment, but the overexpression of glutathione (GSH) and limited endogenous H2O2 make the efficiency of CDT unsatisfactory. Here, an intelligent nanoplatform CuO2@mPDA/DOX-HA (CPPDH), which induced the depletion of GSH and the self-supply of H2O2, was proposed. When CPPDH entered tumor cells through the targeting effect of hyaluronic acid (HA), a release of Cu2+ and produced H2O2 were triggered by the acidic environment of lysosomes. Then, the Cu2+ was reduced by GSH to Cu+, and the Cu+ catalyzed H2O2 to produce •OH. The generation of •OH could be distinctly enhanced by the GSH depletion and H2O2 self-sufficiency. Besides, an outstanding photothermal therapy (PTT) effect could be stimulated by NIR irradiation on mesoporous polydopamine (mPDA). Meanwhile, mPDA was an excellent photoacoustic reagent, which could monitor the delivery of nanocomposite materials through photoacoustic (PA) imaging. Moreover, the successful delivery of doxorubicin (DOX) realized the integration of chemotherapy, PTT, and CDT. This strategy could solve the problem of insufficient CDT efficacy caused by the limited H2O2 and overexpression of GSH. This multifunctional nanoplatform may open a broad path for self-boosting CDT and synergistic therapy.

Abstract
Multimodal nanotherapeutic cancer treatments are widely studied but are often limited by their costly and complex syntheses that are not easily scaled up. Herein, a simple formulation of glucose-oxidase-coated CuS nanoparticles was demonstrated to be highly effective for melanoma treatment, acting through a synergistic combination of glucose starvation, photothermal therapy, and synergistic advanced chemodynamic therapy enabled by near-infrared irradiation coupled with Fenton-like reactions that were enhanced by endogenous chloride.

Abstract
The vascular wall is the first physiologic barrier that circulating nanoparticles (NPs) encounter, which also is a key biological barrier to cancer drug delivery. NPs can continually scavenge the endothelium for biomarkers of cancer, and the chance of NPs' extravasation into the tumors can be enhanced. Here, we envision P-selectin as a target for specific delivery of drug nanocrystals to tumors. The cupric diethyldithiocarbamate nanocrystals (CuET NCs) were first prepared by an antisolvent method, and then nanocrystals were coated with fucoidan via physical interaction. The fucoidan-coated CuET nanocrystals (CuET@Fuc) possess high drug loading and have the ability to interact with human umbilical vein endothelial cells expressing P-selectin, which transiently enhances the endothelial permeability and facilitates CuET@Fuc extravasation from the peritumoral vascular to achieve higher tumor accumulation of drugs than bare CuET NCs. The CuET NC shows poorer anticancer efficacy than CuET@Fuc at the same dose of CuET. Upon repeated dosing of CuET@Fuc for 2 weeks, no mortality was observed in treated melanoma-bearing mice, while the mortality in the control group and excipient-treated groups reached 23%. The growth rate of melanoma in the CuET@Fuc-treated group was significantly lower than those in other groups. Furthermore, an acute toxicity study revealed that CuET@Fuc is a safe formulation for cancer treatment.

Abstract
Patients with myelodysplastic syndromes (MDS) who resist or fail to respond to hypomethylating agents (HMAs) show very poor outcomes and have no effective treatment strategies. Therefore, new therapeutic approaches are urgently needed for MDS patients harboring adverse prognostic factors. Repurposing disulfiram (DSF), an alcohol-abuse drug, with or without Copper (Cu) has attracted considerable attentions as a candidate anti-tumor therapy in diverse malignancies. However, the effect of DSF in the presence or absence of Cu on MDS has not been reported yet. In this study, we found that monotherapy with DSF showed mild cytotoxic effects on MDS preclinical models. However, the anti-tumor activity of DSF was significantly enhanced in the presence of Cu in MDS in vitro and in vivo with minimal safety profiles. DSF/Cu combination blocked MDS cell cycle progression at the G0/G1 phase, accompanied by reduction of the S phase. Accordingly, co-treatment with DSF and Cu downregulated the expression of Cyclin D1 and Cyclin A2, whereas this combination upregulated the level of P21 and P27. Mechanistically, the anti-MDS effectiveness of DSF/Cu was potentially associated with activation of the ER stress-related Bip pathway and inactivation of the Akt pathway. In addition, inhibition of autophagy process also contributed to the cytotoxicity of DSF/Cu in MDS cells. In conclusion, these findings provide impressive evidence that the DSF/Cu complex shows potent anti-tumor efficacies on MDS preclinical models, representing a potential alternative therapy for MDS patients and warranting further investigation in clinical contexts.
