Advanced Healthcare Materials, EarlyView.We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
Advanced Materials, EarlyView.A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Advanced Materials Interfaces, EarlyView.Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development
Advanced Science, EarlyView.This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...
