Rapid Arbitrary‐Shape Microscopy of Unsectioned Tissues for Precise Intraoperative Tumor Margin Assessment

open access: yesAdvanced Science, EarlyView.
This study presents a novel microscopic imaging system capable of rapid, section‐free scanning of irregular tissue surfaces, delivering high sensitivity for detecting cancer cell clusters during intraoperative tumor margin assessment. Abstract Rapid and accurate intraoperative examination of tumor margins is crucial for precise surgical treatment, yet ...

Beyond Catalytic Therapy: Copper‐Paeonol Nanozymes Disrupt Fascin‐Mediated Actin Bundling to Suppress Tumor Growth and Metastasis

open access: yesAdvanced Science, EarlyView.
Copper‐paeonol nanozymes target tumor‐specific reactive oxygen species generation and disrupt fascin‐mediated actin bundling, effectively suppressing tumor growth and metastatic colonization. Abstract Fascin, an actin‐bundling protein universally upregulated in metastatic tumors, drives tumor migration and invasion by promoting filopodia and ...

The Mitochondrial Guardian α‐Amyrin Mitigates Alzheimer's Disease Pathology via Modulation of the DLK‐SARM1‐ULK1 Axis

open access: yesAdvanced Science, EarlyView.
Dietary habits play a key role in chronic diseases, and higher annual consumption of fruit and vegetable may lower risk of dementia. Artificial intelligence predicts the lipid‐like compound α‐Amyrin (αA) from plants with edible peels as a drug candidate against Alzheimer's disease.

CD27 and ICOS as Targets of PD‐1/PD‐L1 Signaling to Regulate Resident Memory CD8+ T‐Cell‐Mediated Pulmonary Protection and Pathology

open access: yesAdvanced Science, EarlyView.
Here it is revealed that the costimulatory receptors CD27 and ICOS are essential for the long‐term maintenance of PD‐1high CD8+ TRM cells following influenza infection. PD‐L1 blockade enhances the proliferation and activation of these cells through Nur77 activation downstream of the CD27/ICOS signaling axis, thereby boosting host immunity against ...

Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

open access: yesAdvanced Science, EarlyView.
This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image
