Functional RNAi screening identifies G2/M and kinetochore components as modulators of TNFα/NF-κB pro-survival signaling in head and neck squamous cell carcinoma.

Immune and radiation resistance of cancer cells to cytotoxicity mediated by Tumor Necrosis Factor-α (TNFα) is promoted by the transcription factor NF-κB in several cancers, including head and neck squamous cell carcinoma (HNSCC). Genomic alterations that converge on the TNFα/NF-κB signal axis were found in ~40% of HNSCCs by The Cancer Genome Atlas (TCGA). However, identification of therapeutic targets that contribute to aberrant TNFα/NF-κB activation and resistance has been challenging. Here, we conducted a functional RNAi screen to identify regulators of TNFα-induced NF-κB activation and cell viability, using parallel NF-κB ß-lactamase reporter and cell viability assays in a HNSCC cell line which harbors expression and genomic alterations typically found in HPV-negative HNSCC. Besides multiple components of canonical TNFα/NF-κB signaling, we identified components of the WNT, NOTCH, and TGFß pathways that we previously showed contribute to non-canonical activation of NF-κB. Unexpectedly, we also observed that multiple G2/M cell cycle kinases (AURKA, PLK1, WEE1, TTK), and structural kinetochore/microtubule components (NDC80, NUF2), modulate TNFα-induced NF-κB activation and cell viability. Several of these targets inhibit TNF-induced nuclear translocation of RELA, consistent with prior reports linking NF-B activation to G2/M kinases or microtubule assembly. Further investigation of an understudied mitotic kinase, TTK/MPS1, show that it's inhibition or depletion attenuates TNFα-induced RELA nuclear translocation, promoting cell death, DNA damage, polyploidy, and mitotic catastrophe, leading to radiosensitization. Together, our RNAi screening identifies a critical linkage between the G2/M cell cycle checkpoint/kinetochore components and NF-κB activity, and as targets that can sensitize HNSCC cells to TNFα or radiation.

Controlling the Polarity of Metal-Organic Frameworks to Promote Electrochemical CO2 Reduction.

The addition of polar functional groups to porous structures is an effective strategy for increasing the ability of metal-organic frameworks (MOFs) to capture CO2 by enhancing interactions between the dipoles of the polar functional groups and the quadrupoles of CO2. However, the potential of MOFs grafted to polar functional group to activate CO2 has not been investigated in the context of CO2 electrolysis. In this study, we report a mixed-ligand strategy to incorporate various functional groups in the MOFs. We found that substituents with strong polarity led to increased catalytic performance of electrochemical CO2 reduction for these polarized MOFs. Both experimental and theoretical evidence indicates that the presence of polar functional groups induces a charge redistribution in the micropores of MOFs. We have shown that higher electron densities of sp2-carbon atoms in benzimidazolate ligands reduces the energy barrier to generate *COOH, which is simultaneously controlled by the mass transfer of CO2. Our research offers an effective method of disrupting local electron neutrality in the pores of electrocatalysts/supports to activate CO2 under electrochemical conditions.

Preclinical immunogenicity and safety of hemagglutinin-encoding modRNA influenza vaccines.

Seasonal epidemics of influenza viruses are responsible for a significant global public health burden. Vaccination remains the most effective way to prevent infection; however, due to the persistence of antigenic drift, vaccines must be updated annually. The selection of vaccine strains occurs months in advance of the influenza season to allow adequate time for production in eggs. RNA vaccines offer the potential to accelerate production and improve efficacy of influenza vaccines. We leveraged the nucleoside-modified RNA (modRNA) platform technology and lipid nanoparticle formulation process of the COVID-19 mRNA vaccine (BNT162b2; Comirnaty®) to create modRNA vaccines encoding hemagglutinin (HA) (modRNA-HA) for seasonal human influenza strains and evaluated their preclinical immunogenicity and toxicity. In mice, a monovalent modRNA vaccine encoding an H1 HA demonstrated robust antibody responses, HA-specific Th1-type CD4+ T cell responses, and HA-specific CD8+ T cell responses. In rhesus and cynomolgus macaques, the vaccine exhibited durable functional antibody responses and HA-specific IFN-γ+ CD4+ T cell responses. Immunization of mice with monovalent, trivalent, and quadrivalent modRNA-HA vaccines generated functional antibody responses targeting the seasonal influenza virus(es) encoded in the vaccines that were greater than, or similar to, those of a licensed quadrivalent influenza vaccine. Monovalent and quadrivalent modRNA-HA vaccines were well-tolerated by Wistar Han rats, with no evidence of systemic toxicity. These nonclinical immunogenicity and safety data support further evaluation of the modRNA-HA vaccines in clinical studies.

Targeted Defect Repair and Multi-functional Interface Construction for the Direct Regeneration of Spent LiFePO4 Cathodes.

Due to the low economic benefits and environmental pollution of traditional recycling methods, the disposal of spent LiFePO4 (SLFP) presents a significant challenge. The capacity fade of SLFP cathode is primarily caused by lithium loss and formation of a Fe (III) phase. Herein, a synergistic repair effect is proposed to achieve defect repair and multi-functional interface construction for the direct regeneration of SLFP. Tannic acid (TA) forms a compact coating precursor for a carbon layer on SLFP with abundant functional groups and creates a mildly acidic environment to enhance the reducibility of thiourea (TU). Therefore, TU reduces Fe (III) to Fe (II) and repairs Li-Fe anti-site defects of SLFP, while at the same time acting as a source of N/S-doping elements for the carbon layer at a lower temperature (140 °C). The multi-functional carbon layer improves the properties of the regenerated LiFePO4 (RLFP) due to the enhanced conductivity, structure maintenance and protection, and the improved kinetics of Li+ transport. Furthermore, the Fe─O and P─O bonds are strengthened, further enhancing the structural stability of the RLFP. Consequently, the RLFP demonstrates outstanding performance with a discharge capacity of 141.3 mAh g-1 and capacity retention of 72% after 1000 cycles at 1 C.

BioPathNet: Enhancing Link Prediction in Biomedical Knowledge Graphs through Path Representation Learning.

Understanding complex interactions in biomedical networks is crucial for advancements in biomedicine, but traditional link prediction (LP) methods are limited in capturing this complexity. Representation-based learning techniques improve prediction accuracy by mapping nodes to low-dimensional embeddings, yet they often struggle with interpretability and scalability. We present BioPathNet, a novel graph neural network framework based on the Neural Bellman-Ford Network (NBFNet), addressing these limitations through path-based reasoning for LP in biomedical knowledge graphs. Unlike node-embedding frameworks, BioPathNet learns representations between node pairs by considering all relations along paths, enhancing prediction accuracy and interpretability. This allows visualization of influential paths and facilitates biological validation. BioPathNet leverages a background regulatory graph (BRG) for enhanced message passing and uses stringent negative sampling to improve precision. In evaluations across various LP tasks, such as gene function annotation, drug-disease indication, synthetic lethality, and lncRNA-mRNA interaction prediction, BioPathNet consistently outperformed shallow node embedding methods, relational graph neural networks and task-specific state-of-the-art methods, demonstrating robust performance and versatility. Our study predicts novel drug indications for diseases like acute lymphoblastic leukemia (ALL) and Alzheimer's, validated by medical experts and clinical trials. We also identified new synthetic lethality gene pairs and regulatory interactions involving lncRNAs and target genes, confirmed through literature reviews. BioPathNet's interpretability will enable researchers to trace prediction paths and gain molecular insights, making it a valuable tool for drug discovery, personalized medicine and biology in general.

Achieving ultrasensitive detection of glyphosate in fruits and vegetables using a triple-mode strategy based on carbon dots nanozymes derived from expired drugs.

Rapid and sensitive detection of glyphosate (GLP) holds significant importance in the monitoring of environmental pollution and potential risks to human health. In this study, carbon dots nanozymes (CDszymes) with peroxidase-like activity were synthesized rapidly using a microwave-assisted method, employing expired drugs as raw materials. In the presence of H2O2, CDszymes catalyze the oxidation of TMB to generate blue oxTMB, which exhibits a photothermal effect under near-infrared light irradiation; an inner filter effect (IFE) may occur between oxTMB and CDszymes. By coupling the cascade catalysis of AChE and ChOx to generate H2O2, GLP effectively inhibits the activity of AChE, constructing a colorimetric/fluorescent/photothermal response platform for GLP. In colorimetry, the detection limit of GLP was 0.33 ng/mL. The detection limits of GLP by fluorescence method and photothermal method were 0.02 ng/mL and 0.41 ng/mL, respectively. The efficacy of this methodology has been successfully demonstrated in fruit and vegetable, it also provides a strategy for the high-value conversion of expired drugs.

B3GALT4 modulates tumor progression and autophagy by AKT/mTOR signaling pathway in breast cancer.

BACKGROUND: ß-1,3-Galactosyltransferase-4 (B3GALT4), a member of the ß-1,3-galactosyltransferase gene family, is essential to the development of many malignancies. However, its biological function in breast cancer is still unknown. METHOD: Publically accessible datasets, as well as quantitative real-time PCR, western blot, and immunohistochemistry on our patient cohort were used to investigate the expression levels of B3GALT4 in breast cancer. The correlation of B3GALT4 expression with clinical histopathological data and mortality in breast cancer patients was investigated. The effects of B3GALT4 in breast cancer in vitro and in vivo were investigated. RNA-seq, western blot, autophagolysosomes, and the fluorescence intensity of LC3 were used to explore the effects of B3GALT4 on autophagy. Western blot and gene set enrichment analysis (GSEA) were used to identify the AKT/mTOR pathway. RESULTS: B3GALT4 was significantly overexpressed in breast cancer tissues and was positively correlated with some aspects of clinicopathological status and poor prognosis. B3GALT4 overexpression significantly promoted cell proliferation, migration, and invasion, both in vitro and in vivo. B3GALT4 inhibition suppressed breast cancer cell proliferation, migration, and invasion in vitro. Suppression of B3GALT4 triggered autophagy and hindered the AKT/mTOR signaling pathway. CONCLUSION: According to the present research, B3GALT4 blocked autophagy via the AKT/mTOR pathway and accelerated the growth of breast cancer. B3GALT4 may be an effective target for patients with breast cancer.

Navigating therapeutic challenges in VEXAS syndrome: exploring IL-6 and JAK inhibitors at the forefront.

VEXAS syndrome, an uncommon yet severe autoimmune disorder stemming from a mutation in the UBA1 gene, is the focus of this paper. The overview encompasses its discovery, epidemiological traits, genetic underpinnings, and clinical presentations. Delving into whether distinct genotypes yield varied clinical phenotypes in VEXAS patients, and the consequent adjustment of treatment strategies based on genotypic and clinical profiles necessitates thorough exploration within the clinical realm. Additionally, the current therapeutic landscape and future outlook are examined, with particular attention to the potential therapeutic roles of IL-6 inhibitors and JAK inhibitors, alongside an elucidation of prevailing limitations and avenues for further research. This study contributes essential theoretical groundwork and clinical insights for both diagnosing and managing VEXAS syndrome.

Idiopathic intracranial hypertension in Asians: a retrospective dual-center study.

BACKGROUND: There have been limited data on idiopathic intracranial hypertension (IIH) in Asians and there remain uncertainties whether a cerebrospinal fluid (CSF) pressure of 250 mm CSF is an optimum diagnostic cutoff. The aims of the present study included (1) characterization of IIH patients in Taiwan, (2) comparisons among different diagnostic criteria for IIH, and (3) comparisons between patients with CSF pressures of > 250 and 200-250 mm CSF. METHODS: This retrospective study involved IIH patients based on the modified Dandy criteria from two tertiary medical centers in Taiwan. Clinical manifestations were retrieved from electronic medical records, and findings on ophthalmologic examination and magnetic resonance images (MRIs) were reviewed. RESULTS: A total of 102 patients (71 F/31 M, mean age 33.4 ± 12.2 years, mean CSF pressure 282.5 ± 74.5 mm CSF) were identified, including 46 (45.1%) with obesity (body-mass index ≥ 27.5), and 57 (62.6%) with papilledema. Overall, 80 (78.4%), 55 (53.9%), 51 (50.0%), and 58 (56.9%) patients met the Second and Third Edition of International Classification of Headache Disorders, Friedman, and Korsbæk criteria, respectively. Patients in the 200-250 mm CSF group (n = 40) were less likely to have papilledema (48.5% vs. 70.7%, p = 0.035), transient visual obscuration (12.5% vs. 33.9%, p = 0.005), and horizontal diplopia (10.0% vs. 30.6%, p = 0.006), and had fewer signs on MRIs (2.2 ± 1.3 vs. 2.8 ± 1.0, p = 0.021) when compared with those with CSF pressures > 250 mm CSF (n = 62). However, the percentages of patients with headache (95.0% vs. 87.1%, p = 0.109) at baseline, chronic migraine at six months (31.6% vs. 25.0%, p = 0.578), and visual field defect (86.7% vs. 90.3%, p = 0.709) were similar. CONCLUSIONS: It was found that obesity and papilledema were less common in Asian IIH patients when compared with Caucasian patients. Although patients with CSF pressures of 200-250 mm CSF had a less severe phenotype, the risks of having headache or visual loss were comparable to those in the > 250 mm CSF group. It is possible that a diagnostic cutoff of > 200 mm CSF could be more suitable for Asians, although further studies are still needed.

Silencing siRNA microneedle patches versus silicone sheets in reducing post-surgical scars: a randomized single-blinded intra-individually controlled clinical trial.

BACKGROUND: A common complication of wounds is exuberant growth of fibrotic scar tissue, which can lead to hypertrophic scars or keloids. There are currently no treatments with good evidence for preventing excessive scar tissue formation. In this study, we explored the use of microneedle patches containing siRNA inhibiting SPARC mRNA in reducing the volume of post-surgical scars. OBJECTIVE: We aim to compare the differences in the volume of post-surgical scars between daily application of siRNA-embedded dissolving microneedle patches and silicone sheets. The primary study outcome measure was the 3D volume of scar elevation.Our hypothesis was that scar formation in the half of the wound treated with siRNA microneedle patches will be lesser, as reflected by a smaller 3D volume, as compared to the half treated with silicone sheets. METHODS: This was an 8-week, single-blinded intra-individually controlled randomised trial in a tertiary dermatological centre. Patients with two-week-old post-operative wounds were recruited. Each half of the scar was randomly assigned to the microneedle patch or silicone sheet. Three-dimensional (3D) volumes were obtained from the scars via a high-resolution scanner at day 0, 30 and 60. RESULTS: At day 30, scars treated with the microneedle patches had a lower geometric mean volume of 0.79mm3 when compared to scars treated with silicone sheets, with a difference in mean percentage volume reduction of 10.70%.At day 60, scars treated with the microneedle patches had a statistically significant lower volume (8.88mm3) when compared to the side treated with silicone sheets (12.77mm3, p=0.005), with a difference in mean percentage reduction of 9.66%. Additionally, there was also a statistically significant difference between the percentage reduction in scar volume, compared to baseline, on the side treated with microneedle patches (mean=83.78%) compared to the side treated with silicone sheets (mean=74.11%). CONCLUSIONS: There was a significantly greater reduction in the volume of post-surgical scars on the side treated with microneedle patches compared to the side treated with silicone sheets. This demonstrates the use of transdermal gene silencing technology for scar inhibition and that siRNA microneedle patches can be an effective and safe modality in the reduction of scar tissue formation.

High Mass Transfer Rate in Electrocatalytic Hydrogen Evolution Achieved with Efficient Quasi-Gas Phase System.

The adhesion of H2 bubbles on the electrode surface is one of the main factors limiting the performance of H2 evolution of electrolytic water, especially at high current density. To overcome this problem, here a "quasi-gas phase" electrolytic water reaction system based on capillary effect is proposed for the first time to improve the mass transfer efficiency of H2. The typical feature of this reaction system is that the main site of H2 evolution reaction is transferred from the bulk aqueous solution to the gas phase environment above the bulk aqueous solution, thus effectively inhibiting the aggregation of H2 bubbles and reducing the resistance of their diffusion away. Electrochemical test results show that the proposed quasi-gas phase system can significantly reduce the potential required in H2 evolution reaction process at high current density compared with the conventional electrolytic reaction system. Specifically, the overpotential potential is reduced by 0.31 V when the H2 evolution current density of 250 mA cm-2 is achieved.

Triple-negative breast cancer treatment with core-shell Magnetic@Platinium-Metal organic framework/epirubicin nano-platforms for chemo-photodynamic based combinational therapy: A review.

The combination of chemotherapy and photodynamic therapy (PDT), enabled by core-shell nano-platforms, is a promising method to improve cancer therapy by overcoming hypoxia and boosting drug penetration in breast tumor. Core-shell magnetic (iron oxide: Fe3O4)@platinum-metal organic framework/epirubicin (abbreviated as M@Pt-MOF/EPI) nano-platform is considered an effective cancer therapeutic agent. Relatively small particle size, round shape, and specific response to pH, are the key features of these nanomaterials to be used as promising therapeutic agents. Chemotherapy and photodynamic therapy, when applied in addition to the anticancer effects of nanomaterials, further enhance the therapeutic efficacy. The extensive use, utilization, and efficacy of Core-Shell Magnetic@Platinium-Metal Organic Framework/epirubicin Nano-Platforms for chemo-photodynamic combination therapy in the treatment of several cancers, including triple-negative breast cancer, are examined in this in-depth investigation.

The safety and effectiveness of music medicine as an intervention for depression: A systematic evaluation and re-evaluation.

BACKGROUND: As the methodological quality and evidence level of the existing systematic reviews (SRs) on music as an intervention for depression have not been thoroughly evaluated, a systematic evaluation and re-evaluation (SERE) was conducted. METHODS: Multiple databases including PubMed, Web of Science, Embase, China National Knowledge Infrastructure, SinoMed, Wanfang, and the VIP database were searched for SRs and meta-analyses (MAs) on the effectiveness of music as an intervention for depression. The literature screening, evaluation of methodological quality, and assessment of evidence level were carried out by a team of researchers. The methodological quality was evaluated using the Assessment of Multiple Systematic Reviews 2 (AMSTAR 2) scale in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria were utilized to assess the level of evidence. RESULTS: A total of 18 SRs were included in the analysis. The 2020 PRISMA guidelines were utilized to evaluate various aspects such as search terms, funding sources, statistical methods for missing values, subgroup and sensitivity analyses, certainty assessment, excluded literature citations, assessment of publication bias, protocol information, conflicts of interest, and data availability, which were rarely reported. The evaluation of the studies using the AMSTAR 2 scale revealed that one article was rated as high quality, six were rated as low quality, and 11 were rated as very low quality. Based on the GRADE criteria evaluation, the quality of the evidence was found to be inconsistent, with reports primarily consisting of medium-quality evidence. CONCLUSION: The methodological quality of SRs/MAs of music as an intervention in depression is generally poor, and the level of evidence is generally low.

Surface Catalytic Repair for the Efficient Regeneration of Spent Layered Oxide Cathodes.

Direct recycling is considered to be the next-generation recycling technology for spent lithium-ion batteries due to its potential economic benefits and environmental friendliness. For the spent layered oxide cathode materials, an irreversible phase transition to a rock-salt structure near the particle surface impedes the reintercalation of lithium ions, thereby hindering the lithium compensation process from fully restoring composition defects and repairing failed structures. We introduced a transition-metal hydroxide precursor, utilizing its surface catalytic activity produced during annealing to convert the rock-salt structure into a layered structure that provides fast migration pathways for lithium ions. The material repair and synthesis processes share the same heating program, enabling the spent cathode and added precursor to undergo a topological transformation to form the targeted layered oxide. This regenerated material exhibits a performance superior to that of commercial cathodes and maintains 88.4% of its initial capacity after 1000 cycles in a 1.3 Ah pouch cell. Techno-economic analysis highlights the environmental and economic advantages of surface catalytic repair over pyrometallurgical and hydrometallurgical methods, indicating its potential for practical application.

Comprehensive review of perioperative factors influencing ferroptosis.

The perioperative period encompasses all phases of patient care from the decision to perform surgery until full recovery. Ferroptosis, a newly identified type of regulated cell death, influences a wide array of diseases, including those affecting the prognosis and regression of surgical patients, such as ischemia-reperfusion injury and perioperative cognitive dysfunction. This review systematically examines perioperative factors impacting ferroptosis such as surgical trauma-induced stress, tissue hypoxia, anesthetics, hypothermia, and blood transfusion. By analyzing their intrinsic relationships, we aim to improve intraoperative management, enhance perioperative safety, prevent complications, and support high-quality postoperative recovery, ultimately improving patient outcomes.

Establishment of an Animal Model of Oral Squamous Cell Carcinoma Invading the Mandible.

OBJECTIVE: To establish an animal model of oral squamous cell carcinoma invading the mandible through multi-sample experiments that verified the stability, repeatability, tumorigenicity and mandible destruction rate of the model. METHODS: Oral squamous cell carcinoma cell suspension was injected into the outer side of the mandible through the anterior edge of the masseter muscle of naked mice to observe the tumourforming process. Then, the anatomical, histological and imaging examinations were carried out to determine whether the tumour had invaded the mandible. By comparing the tumour growth of multiple groups of various squamous cell carcinoma cells (CAL27, HN6 and HN30 cells), the changes in body weight and characteristics of tumour formation were compared, and the experience was summarised to further verify the stability, repeatability, tumour formation rate and arch damage rate of the model. RESULTS: The subsequent specimens of tumour-bearing nude mice were validated once the model had been established. In vitro, tumour tissue wrapped around the mandible's tumour-bearing side, and the local texture was tough with no resistance to acupuncture. Haematoxylin and eosin staining revealed that squamous cells were infiltrating the mandible in both the horizontal and sagittal planes. Microcomputed tomography results showed that the mandible on the tumour-bearing side displayed obvious erosion damage. Cell lines with various passage rates clearly had diverse tumour-bearing life cycles. CONCLUSION: This study successfully established an animal model of oral squamous cell carcinoma invasion of the mandible. The model has excellent biological stability, repeatability, tumorigenesis rate and mandible destruction rate.

2D Differential Metallic Immunopotentiators Drive High Diversity and Capability of Antigen-specific Immunity Against Tumor.

The therapeutic efficacy of vaccines for treating cancers in clinics remains limited. Here, a rationally designed cancer vaccine by placing immunogenically differential and clinically approved aluminum (Al) or manganese (Mn) in a 2D nanosheet (NS) architecture together with antigens is reported. Structurally optimal NS with a high molar ratio of Mn to Al (MANS-H) features distinctive immune modulation, markedly promoting the influx of heterogeneous innate immune cells at the injection site. Stimulation of multiple subsets of dendritic cells (DCs) significantly increases the levels, subtypes, and functionalities of antigen-specific T cells. MANS-H demonstrates even greater effectiveness in the production of antigen-specific antibodies than the commercial adjuvant (Alhydrogel) by priming T helper (Th)2 cells rather than T follicular helper (Tfh) cells. Beyond humoral immunity, MANS-H evokes high frequencies of antigen-specific Th1 and CD8+ cell immunity, which are comparable with Quil-A that is widely used in veterinary vaccines. Immunized mice with MANS-H adjuvanted vaccines exert strong potency in tumor regression by promoting effector T cells infiltrating at tumor and overcoming tumor resistance in multiple highly aggressive tumor models. The engineered immunogen with an intriguing NS architecture and safe immunopotentiators offers the next clinical advance in cancer immunotherapy.

An Artificial Leaf with Patterned Photocatalysts for Sunlight-Driven Water Splitting.

Plant leaves can turn entirely absorbed light into chemical energy due to their spatially separated photosystems I and II in the thylakoid membrane that enables unidirectional Z-scheme type charge transfer between them. In artificial systems that mimic leaves, a lack of spatial and interfacial control of active units (i.e., hydrogen evolution photocatalyst/HEP and oxygen evolution photocatalyst/OEP) introduces competitive charge transfer channels between them, resulting in deficient Z-scheme type charge transfer. Herein, we demonstrate that a patterned photocatalyst sheet, namely, an artificial leaf, comprising an ordered and separated distribution of the OEP and HEP strips on a conductive substrate, achieves unidirectional Z-scheme type charge transfer as the leaves do. It represents a next-generation photocatalytic system that mimics the leaves to bring breakthrough in photocatalytic over water splitting performance with the combination of highly active HEP and OEP photocatalysts, opening up a promising avenue toward solar energy conversion by artificial photosynthesis.

A Dynamically Ion-Sieved Electrolyte towards Ultralong-Lifespan Zn-Ion Batteries.

The practical deployment of Zn-ion batteries faces challenges such as dendrite growth, side reactions and cathode dissolution in traditional electrolytes. Here, we develop a highly conductive and dynamically ion-sieved electrolyte to simultaneously enhance the Zn metal reversibility and suppress the cathode dissolution. The dynamic ion screen at the electrode/electrolyte interface is achieved by numerous pyrane rings with a radius of 3.69 Å, which can selectively facilitate the plating/stripping and insertion/extraction process of [Zn(H2O)6]2+ and Zn2+ on the anode and cathode surfaces. As a proof of concept, Zn//Zn symmetric cells deliver exceptional cyclic stability for over 6,800 h and ultrahigh cumulative plated capacity of 3.9 Ah cm-2. Zn//Na2Mn3O7 cells exhibit satisfactory cycling performance with capacity retention of 82.7% after 4,000 cycles, and the assembled pouch cells achieve excellent stability and durability. This work provides valuable insights into the development of electrolytes aimed at enhancing the interface stability of aqueous batteries.
