Advances in flexible electronics enable force myography (FMG) and surface electromyography (sEMG) signals for muscle activation monitoring, but the multi-sensor integration and physiological mechanisms underlying FMG signals remain poorly studied, limiting the accuracy of muscle function assessments and underutilizes the high sensitivity of the flexible sensors. This study introduces a novel thin-film iontronic force-electromyography (iFEMG) sensor, integrating a high-sensitivity iontronic pressure sensor and sEMG electrodes for high-fidelity muscle physiological signal acquisition. Based on ultrasound imaging and statistical analysis, the relationship between muscle force, muscle geometric features, and FMG signals is established, providing evidence for elucidating the physiological mechanisms of FMG signals. Based on these findings, an effective and highly adaptable method is proposed for precise muscle force prediction. The iFEMG system is successfully applied to assess motor nerve and muscle function in patients, demonstrating its clinical utility. This system holds significant potential for broader applications, such as rehabilitation training and early diagnosis of musculoskeletal disorders, paving the way for advanced personalized healthcare solutions.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2500843"},"PeriodicalIF":10.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many clinical isolates have shown strong resistance to commonly used antibacterial agents. Inspired by cationic amphiphiles with tandem-repeat sequence, two novel peptides termed IW (IWRRIWRRIWRRIWRR-NH2) and WI (WIRRWIRRWIRRWIRR-NH2) are designed, synthesized, and investigated in this study. Both exhibited favorable antibacterial activity against \"superbugs\" at micromole level, surpassing conventional antibiotics, like meropenem and imipenem. Adopting the analytic strategies of molecular dynamics simulation in combination with experimental verification, lipopolysaccharide (LPS) is proposed as a potential target for IW with a calculated dissociation constant of 886 ± 879 nM. Though deadly to infamous bacteria, IW demonstrated negligible toxicity to Galleria mellonella (GM) larvae at 500 mg kg-1. For better administration, IW was formulated with a commercial pharmaceutical excipient poloxamer 407 (P407) to fabricate an antibacterial colloid. This material was verified to effectively reduce the bacterial burden of Escherichia coli-infected skin in a mouse model by ≈1.5 log compared with the P407-treated group. Overall, this work expanded the potential arsenal against carbapenem-resistant strains by introducing a new engineered molecule delivered using a cheap, concise formulation strategy accordingly.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2500659"},"PeriodicalIF":10.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-mobility group 1B protein (HMGB1) and advanced glycation end products (AGEs) are key RAGE ligands. Simultaneous inhibition of HMGB1/RAGE and AGEs/RAGE pathways maybe an effective strategy to alleviate glycation induced skin damage. In this work, Theasinensin A (TSA) is identified as the active molecule inhibiting HMGB1-RAGE interaction through molecular docking. To simultaneously suppress HMGB1/RAGE and AGEs/RAGE pathways, Zn-based multi-active framework nanoparticles TSA-CAN-Zn are designed, which contain TSA and the active molecule L-carnosine (CAN) that inhibits AGEs production. In vitro studies demonstrated that TSA-CAN-Zn have radical scavenging activity and AGEs formation inhibition activity. TSA-CAN-Zn can not only inhibit ROS accumulation, cell apoptosis, and inflammatory factors production induced by glycation in HaCaT cells but also enhanced the lysosomal degradation of AGEs. TSA-CAN-Zn also mitigated the damage caused by glycation in mouse skin glycation model. Single-cell RNA sequencing results revealed the impact of TSA-CAN-Zn on different cell types of skin tissue, especially the basal cells of the epidermal layer and inflammation-related macrophages. And pathway analysis revealed that TSA-CAN-Zn mainly influences the downstream pathways of RAGE. Collectively, TSA-CAN-Zn is a promising therapeutic candidate for ameliorating glycation-induced skin damage.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2500664"},"PeriodicalIF":10.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although nucleic acid therapy is considered ideal for the development of novel therapeutic strategies, its clinical application still faces numerous challenges, including the lack of efficient delivery systems, insufficient drug formulation stability, and the limitations imposed by the skin barrier on drug dosage delivery. Microneedles, as an innovative transdermal drug delivery technology, can penetrate the stratum corneum and directly access the skin's microcirculation, enabling the efficient delivery of genes and drugs. This technology offers several advantages, such as ease of operation, minimally invasive and painless application, and high safety. Combining microneedle technology with nucleic acid therapy fully leverages the strengths of both approaches, significantly enhancing therapeutic efficacy and bioavailability while maximizing treatment potential.

To analyze the effects of dynamic mechanical stimulation of substrates on cell behavior and skin wound healing, collagen-like hydrogel nanofibers are fabricated using coaxial electrospinning of gelatin methacryloyl (GelMA) and poly-L-lactic acid (PLLA). These nanofibers are then grafted with thermoresponsive poly(N-vinylcaprolactam) (PNVCL) via dehydration condensation reaction, providing temperature-dependent mechanical signals. The incorporation of PLLA significantly enhanced the mechanical properties of the GelMA hydrogel nanofibers, while the subsequent grafting of PNVCL effectively reduced the swelling ratio and porosity. Upon exposure to temperatures above the lowest critical solution temperature (LCST), PNVCL molecules underwent a phase transition and self-contraction, improving mechanical properties by forming robust hydrogen bonds with GelMA and expelling water molecules from the polymer matrix. This dynamic mechanical stimulation further promoted cytoskeletal remodeling of mouse skin fibroblasts (MSFs) without significantly affecting cell proliferation and migration. Additionally, it stimulated the differentiation of fibroblasts into myofibroblasts, thereby enhancing extracellular matrix secretion and skin regeneration in vivo. Overall, the engineering of thermoresponsive hydrogel nanofibers with dynamic mechanical stimulation introduces a novel design paradigm in functional tissue engineering, enabling precise regulation of cellular behaviors for effective skin wound healing.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2500277"},"PeriodicalIF":10.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a non-decellularized cryopreserved aortic allograft (CAo) is investigated as a scaffold for tracheal cartilage regeneration. Originally used to reconstruct infected aortas, CAo retains key features of a large artery-abundant elastic fibers and smooth muscle cells-and demonstrates favorable in vitro biocompatibility with chondrocytes. A trachea-CAo patch construct maintains tensile properties comparable to native trachea and tolerates normal expiratory forces. In a rabbit patch-defect model, CAo elicits only a mild-to-moderate immune response that gradually subsides. Within one month of implantation, robust neocartilage formation is observed, along with angiogenesis and epithelial regeneration. Over the next 12 months, the original aortic scaffold progressively degrades, while newly formed cartilage-originating from recipient perichondrial chondroprogenitor cells-replaces it. Proteomic analyses show that CAo is enriched in cytoskeletal, adhesion, cell migration, and extracellular matrix (ECM)-related proteins, with fibroblast growth factor 2 emerging as a critical mediator of chemotaxis and chondrogenic differentiation. These findings indicate that CAo serves as both a structural and biological scaffold, activating tracheal cartilage regeneration through synergistic biocompatibility, growth factor signaling, and ECM support.","PeriodicalId":113,"journal":{"name":"Advanced Healthcare Materials","volume":" ","pages":"e2405106"},"PeriodicalIF":10.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143953112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, Janus piezoelectric nanoparticles (NPs) are proposed to spatially immobilize glucose oxidase (GOx) and catalase (CAT), enabling piezoelectric potential-amplified enzyme activities and synergistic PEDT-starvation tumor therapy. Here hollow barium titanate (hBT) NPs are synthesized using SiO2 templates, followed by partial Au deposition via the Pickering emulsion-masking method to create Janus hBT@Au NPs, which are then conjugated with GOx and CAT on opposing sides to yield C-hBT@Au-G NPs. The hollow structure of hBT enhances flexibility and deformation under ultrasonication, while Schottky heterojunctions with Au layers promote charge carrier transfer, amplifying piezoelectric effects and free electron transfer to boost GOx activities. Piezoelectric field-enhances selective tumor cell internalization of NPs and PEDT generation of reactive oxygen species (ROS), coupled with self-propagated GOx/CAT cascades, intensify tumor cytotoxicities and deplete intracellular adenosine triphosphate. The Janus architecture, ultrasonic cavitation, and O2 generation collaboratively drive robust propulsion for efficient NP accumulation and deep ROS penetration into tumor tissues, thereby achieving full tumor suppression with negligible systemic toxicity.
