Brain‐Wide Spatiotemporally Distinct Traveling Waves Drive Anxiety‐Like Behaviors in Mice

Advanced Science, EarlyView.
J.Liu et al. reveal the complete propagation dynamics of cortical traveling waves, from local circuitry initiation to long‐range propagation, and identify their functional relevance in modulating anxiety‐like behaviors and underlying cellular neuroplasticity in mice.

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

Advanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Graphics processing unit accelerating compressed sensing photoacoustic computed tomography with total variation [PDF]

, 2020
Photoacoustic computed tomography with compressed sensing (CS-PACT) is a commonly used imaging strategy for sparse-sampling PACT. However, it is very time-consuming because of the iterative process involved in the image reconstruction.

A Herbal‐Piezoelectric Heterojunction Strategy to Potentiate Bacterial Cuproptosis‐Like Death and Remodel the Inflammatory Microenvironment in Infection‐Associated Implant Osteomyelitis

Advanced Science, EarlyView.
A titanium implant coating integrating berberine and copper‐doped strontium titanate leverages ultrasound to compromise bacterial membranes and induce cuproptosis‐like death. This approach resolves S. aureus infections in osteomyelitis models while suppressing inflammation and promoting osseointegration, demonstrating a dual‐functional strategy against

Quantitative Photo-acoustic Tomography with Partial Data

, 2012
Photo-acoustic tomography is a newly developed hybrid imaging modality that combines a high-resolution modality with a high-contrast modality. We analyze the reconstruction of diffusion and absorption parameters in an elliptic equation and improve an ...

Senescence‐Inducing Therapy Sequential NIR‐II Mild Photothermal/Senolytic Therapy of Triple Negative Breast Cancer

Advanced Science, EarlyView.
Targeting triple‐negative breast cancer remains challenging due to limited therapies and drug resistance. A sequential theranostic strategy combining palbociclib‐induced senescence (enhancing heat sensitivity via HSP70 downregulation) with an NIR‐II nanoplatform (IQ NPs) for mild photothermal therapy (PTT) and quercetin‐mediated senolysis is developed.
