Real‐Time In Vivo Cellular‐Level Imaging During Puncture

Advanced Science, EarlyView.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Mechanical Characteristics of the Main Tower of a Polygonal Line Tower Cable-Stayed Bridge

Advances in Civil Engineering, 2020
The main tower of a polygonal line tower cable-stayed bridge bears most of the axial force transmitted by the stay cable and also bears the moment under certain unbalanced load. For a polygonal line tower cable-stayed bridge, the main tower has a bending

Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes

Advanced Science, EarlyView.
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

The Microbiota Shapes Central Nervous System Myelination in Early Life

Advanced Science, EarlyView.
Gut microbiota shapes brain development by regulating myelination and glial cell maturation in early life. Using germ‐free (GF) mice and zebrafish, this study reveals sex‐ and age‐dependent effects on myelin growth, integrity, and related gene expression.
