Direct‐Ink‐Writing Printed Stretchable Eutectic Gallium–Indium Antenna for Robust Wireless Communication

Advanced Science, EarlyView.
In summary, a universal EGaIn‐based DIW printing strategy is presented for fabricating wideband stretchable antennas. The printed antenna achieves an operating bandwidth of 3.75–8.21 GHz (fractional bandwidth: 75%), a peak gain of 1.8 dB and a radiation efficiency of 76.6%, surpassing state‐of‐the‐art stretchable antennas. More importantly, the antenna

CXCL13 Damages Blood Spinal Cord Barrier by Promoting RNF6/Sqstm1‐Ubiquitination Induced Autophagy in Experimental Allergic Encephalomyelitis

Advanced Science, EarlyView.
In multiple sclerosis, the disruption of the blood‐spinal cord barrier (BSCB) induced by CXCL13 facilitates the infiltration of inflammatory cells into the central nervous system, resulting in demyelination and neuronal injury. Mechanistically, the deleterious impact of CXCL13 on the BSCB is associated with a reduction in tight junction protein ...
