Summary: This study aims to construct bio-targeted oxygen production probes consisting of Bifidobacterium that naturally target the hypoxia region of the tumor and multi-functional oxygen-producing nanoparticles equipped with IR780, perfluorohexane (PFH), CBP (carboplatin), and oxygen. The probes are expected to achieve targeted and synergistic focused ultrasound ablation surgery (FUAS) therapy and dual-mode imaging to mediate tumor diagnosis and treatment. The strategy can potentially alleviate tumor hypoxia, avoid tumor drug resistance, improve the effect of chemotherapy, and provide the foundation for future tumor therapy progress.

Summary: This study aims to predict the outcome of unconscious acquired brain injury patients and differentiate consciousness levels using brain functional imaging and machine learning techniques. The researchers construct functional networks based on resting-state fMRI and use connection strengths as features for outcome prediction and consciousness level differentiation. The study achieves improved classification accuracy for consciousness levels (84.78%) and recovery outcome prediction (89.74%) compared to other methods, and identifies contributive connections across the entire brain. These findings provide potential biomarkers for understanding consciousness and developing diagnostic, prognostic, and therapeutic guidelines for ABI patients.

Summary: The study developed an ultrafast ultrasound vector Doppler (ultrafast UVD) method for small vasculature hemodynamic imaging by combining multiangle vector Doppler strategy and ultrafast sequencing. The validity of the technique was demonstrated through experiments on a rotational phantom, rat brain, human brain, and human spinal cord. Compared with the widely accepted accurate flow velocimetry technique ultrasound localization microscopy (ULM), the rat brain experiment showed that the average relative error (ARE) of the velocity magnitude estimated by ultrafast UVD was approximately 16.2%, with a root-mean-square error (RMSE) of the velocity direction of 26.7°. The results demonstrated that ultrafast UVD is a promising tool for accurate blood flow velocity measurement, especially for organs with vasculature typically exhibiting tendential alignment of vascular trees, such as the brain and spinal cord.
