Spatiotemporal Co‐Delivery of Hydrogen and Magnesium via Microneedle Patches for Neuroinflammation Modulation After Spinal Cord Injury: A Multi‐Modal In Vivo Study

Small, EarlyView.
A spatiotemporal co‐delivery microneedle system (MN‐Mg) is developed for spinal cord injury repair. By generating hydrogen gas and magnesium ions in situ, this dual‐engine platform effectively scavenges ROS and modulates microglial polarization via the MAPK/AP‐1 signaling axis.

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...
