Investigation of iterative image reconstruction in three-dimensional optoacoustic tomography

, 2012
Iterative image reconstruction algorithms for optoacoustic tomography (OAT), also known as photoacoustic tomography, have the ability to improve image quality over analytic algorithms due to their ability to incorporate accurate models of the imaging ...

Human Nervous System‐Based Biohybrid Robot‐On‐A‐Chip with Sensing Function for Toxicity Screening

Advanced Science, EarlyView.
Human nervous system‐based biohybrid robot‐on‐a chip with eye function as sensing system in addition to brain/motor neuron/muscle functions is proposed. Upon light stimulation, the eye assembloid generates electrophysiological signals, which are transmitted through the cerebral organoid and motor neuron spheroid, inducing muscle movement.

Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

Advanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

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.

HIFU‐Driven Targeted Pyroptosis Therapy in Basal‐Like Breast Cancer

Advanced Science, EarlyView.
This study presents a HIFU‐driven pyroptosis strategy for BLBC treatment. Combining HIFU with platelet‐membrane hybridized liposomes encapsulating mitoxantrone enhances tumor targeting and efficacy. The synergistic treatment modulates key epigenetic regulators and activates the pyroptotic pathway through ROS generation and inflammasome signaling ...
