Current practices relying on manual control of infusion pumps often result in unpredictable drug delivery profiles and dosing errors—key issues highlighted by the United States Food and Drug Administration (FDA). To address these issues, we introduce the SMART (synchronized‐pump management algorithms for reliable therapies) framework, a novel approach that leverages low Reynolds number drug transport physics and machine learning to accurately manage multidrug infusions in real‐time. SMART is activated based on the Shafer number (), a novel non‐dimensional number that quantifies the relative magnitude of a drug's therapeutic action timescale to its transport timescale within infusion manifolds. SMART is useful when , where drug transport becomes the rate limiting step in achieving the desired therapeutic effects. When activated, SMART monitors multidrug concentrations within infusion manifolds and leverages this information to perform end‐to‐end management of drug delivery using an ensemble of deterministic and deep reinforcement learning (RL) decision networks. Notably, SMART RL networks employ differentially sampled split buffer architecture that accelerates learning and improves performance by seamlessly combining deterministic predictions with RL experience during training. SMART deployed in standalone infusion pumps under simulated clinical conditions outperformed state‐of‐the‐art manual control protocols. This framework has the potential to revolutionize critical care by enhancing accuracy of medication delivery and reducing cognitive workloads. Beyond critical care, the ability to accurately manage multi‐liquid delivery via complex manifolds will have important bearings for manufacturing and process control.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"55 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653389","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, we first discovered and validated that the S100A8/9 specific inhibitor Paquinimod could inhibit macrophage polarization toward M1, and further suppress the proliferation, migration, collagen formation, and angiogenesis of HSFBs and HDVECs in vitro. This mechanism has also been validated in a rat model of HS. Then, we developed a good biocompatibility and penetrability Paquinimod‐Hydrogel Hybrid Microneedle Array Patch (PHMAP) for HS treatment. With the advantages of excellent penetrability, surface sealing, sustained release, and precise uniform distribution, PHMAP exhibited superior therapeutic efficacy over intravenous and intradermal injections.

The severe side effects associated with high‐dose chemotherapy further complicate treatment. Despite significant advancements in drug screening, traditional platforms remain limited due to their requirement for large cell quantities and their low translational success from bench to clinic. These limitations hinder the application of personalized medicine screening for patients with neuroblastoma. To address these challenges, we developed a Bioinspired Nanodroplet Processing (BioNDP) platform. This innovative platform allows for the simultaneous screening of multiple drug combinations while reducing the required number of cells to just 100 and minimizing assay volumes to 200 nL per well. Using BioNDP, we screened chemotherapeutic combinations of cyclophosphamide, doxorubicin, and vincristine in both the SK‐N‐DZ neuroblastoma cell line and primary neuroblastoma cells derived from TH‐MYCN transgenic mice. Our findings revealed a specific drug combination that exhibited significant synergistic cytotoxicity in neuroblastoma cells. This combination completely eradicated tumors and significantly improved survival rates in TH‐MYCN mice, without notable side effects. This study highlights the potential of the BioNDP platform in bridging in vitro and in vivo results, offering a promising strategy for personalized medicine in the treatment of HR neuroblastoma, with reduced toxicity and enhanced therapeutic efficacy.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"13 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143607892","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}

The current standard of care combines muscle autografting with physical therapy but is often insufficient to reach full recovery. Decellularized skeletal muscle (DSM) provides an interesting alternative to repair volumetric muscle loss. The native structure and composition of the extracellular matrix in these acellular implants provide a blueprint for muscle regeneration. Moreover, DSM can be combined with cells to facilitate the regeneration of the skeletal muscle defect. This systematic review provides a complete and thorough overview of the state‐of‐the‐art applications and efficacy of DSM matrices in skeletal muscle repair in vivo, selected according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Technical information on the different methods to create DSM implants and the implantation studies is provided. Moreover, details on the evaluation of the structural and functional regeneration of the muscle defect after implantation of the DSM are described. Results reveal a large heterogeneity in the analysis of regeneration upon DSM implantation. This heterogeneity makes it difficult to fully assess the efficiency of DSM to regenerate skeletal muscle, hampering further translation of this technique. Therefore, we suggest a multi‐level evaluation method to assess (i) muscle regeneration, (ii) vascularization, (iii) innervation of the regenerated muscle, and (iv) functional regeneration in a quantitative way.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"32 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143607890","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}

Current thrombolytic therapies using tissue plasminogen activator (tPA) are limited by low recanalization rates and risks of off‐target bleeding. Here, we demonstrate that a remarkably simple adjustment—using micrometer‐scale rather than sub‐micrometer particles to immobilize tPA—fundamentally improves thrombolysis. By merely increasing the particle diameter from 0.1 to 1.0 μm, we achieve a dramatic shift in lysis dynamics: 1.0 μm tPA‐beads generate higher plasmin flux, readily overcome antiplasmin inhibition, and trigger a self‐propagating cascade of fibrinolysis. This leads to near‐complete clot dissolution at tPA doses nearly 100‐fold lower than standard free tPA, both in vitro and in a murine model of acute ischemic stroke. Within minutes, low‐dose 1.0 μm tPA beads fully restore blood flow, outperforming conventional therapies. Our results show that simply scaling up particle size can resolve kinetic and transport barriers in thrombolysis, offering a promising advancement in stroke treatment with potential applications in other thrombotic disorders.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"54 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143607889","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}

Here, we present a novel and highly tunable in vitro model of the human mvBM, enabling a bottom‐up approach to assemble a composite model of the microvascular wall and explore microvascular dynamics and interactions with circulating neutrophils in real time. An electrospun polyethylene glycol (PEG)‐based fibrillar network mimics the mvBM with adjustable nanofiber diameter, orientation, and density. The fidelity of the model to the human mvBM's topography and mechanics was verified through second harmonic generation imaging and atomic force microscopy. PEG was functionalized with bioactive moieties to enable endothelial cell (EC) and pericyte (PC) attachment, through which neutrophil interactions with the microvascular wall model were observed. The model, coupled with 4D microscopy, revealed nuanced and dynamic neutrophil behavior when interacting with the microvascular wall, demonstrating its utility in characterizing cell–cell interactions. As such, the model can be employed in the exploration of inflammatory and microvascular‐related diseases. Therefore, this innovative approach represents a significant advancement in vascular biology research, holding profound implications for understanding mvBM dynamics in both health and disease.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"5 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143607891","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}
