This study identifies a conserved hyaluronan-centered extracellular matrix regulatory axis linking traumatic brain injury, spinal cord injury, and neural implant responses, suggesting that HA-associated signatures can serve as minimally invasive biomarkers for monitoring neural injury and implant biocompatibility.
This study demonstrates that bioimpedance monitoring provides a real-time, waveform-agnostic metric for tracking cardiac electroporation during pulsed field ablation, while revealing that the procedure-induced increase in tissue conductivity homogenizes myocardial anisotropy, thereby supporting simplified modeling and the derivation of validated lethal electric field thresholds.
This study demonstrates that a retaining GH1 -glycosidase can be engineered through targeted mutations of second-shell residues to acquire -glycosidase activity while maintaining its native -function, thereby proving that the stereochemical constraints of this enzyme family are more flexible than previously thought.
This study introduces a 3D organotypic artery-graft culture platform that enables non-destructive, longitudinal multiphoton imaging of tissue remodeling, successfully correlating short-term in vitro responses to specific TGF-beta isoforms and graft designs with long-term in vivo outcomes to facilitate the pre-clinical optimization of vascular grafts.
This study demonstrates that engineering mesoscale microtrenches on cardiovascular biomaterials stabilizes endothelial monolayers under extreme shear by creating protective flow gradients that promote mechanoadaptation, enhance nitric oxide production, and suppress inflammatory activation, thereby offering a material-agnostic strategy to improve the hemocompatibility of high-shear implants.
This study demonstrates that a continuous bioreactor, optimized for specific environmental conditions and inoculated with either nasal swab specimens or synthetic microbial communities, can maintain stable, reproducible nasal microbiomes for over a month, providing a robust model for investigating nasal ecology and developing targeted *Staphylococcus aureus* decolonization strategies.
This study presents a gold nanoparticle-assisted optoporation technique that enables spatially selective gene delivery to tumor-associated macrophages within 3D pancreatic cancer spheroids, successfully reprogramming them to an anti-tumorigenic state and modulating the tumor microenvironment.
This paper introduces a novel method for generating ventral and dorsal forebrain organoids that accurately recapitulate the macroscale geometry and tissue architecture of the developing telencephalon by utilizing an endothelial cell growth medium to expand the neuroepithelium and embedding the organoids in miniature collagen spheres to stabilize their structure and support neurovascular development.
This study demonstrates that a novel sublingual, orally disintegrating tablet vaccine (Capot) utilizing bacterial extracellular vesicles encapsulated in a calcium phosphate nanoshell effectively induces durable salivary sIgA immunity and provides robust protection against periodontitis in mice and non-human primates without causing inflammation.
This study utilizes simulations of SHG-informed fiber networks to demonstrate that while collagen fiber crimp does not influence diffusion tensor MRI metrics, fiber dispersion significantly alters axial and radial diffusivity as well as fractional anisotropy, thereby clarifying the relationship between microstructural variations and DTI measurements in tendons and ligaments.
