Neuroengineering approaches assessing structural and functional changes of motor descending pathways in stroke.

Stroke is a leading cause of adult disability worldwide, with approximately 101 million survivors globally. Over 60% of these individuals live with from long-term, often lifelong, movement impairments that significantly hinder their ability to perform essential daily activities and maintain independence. Post-stroke movement disabilities are highly associated with structural and functional changes in motor descending pathways, particularly the corticospinal tract (CST) and other indirect motor pathways via the brainstem.

High-contrast dual-modal imaging of absorption and scattering using low-rank and sparse matrix decomposition of light fields.

Optical absorption and scattering are critical properties of biological tissues, but strong background light often obscures this information, limiting imaging contrast and the visualization of tissue microstructures. Current methods for enhancing imaging contrast rely on image processing and noise suppression, but often lose critical details under strong background light. To address this issue, we propose a dual-modal imaging technique based on a low-rank and sparse matrix decomposition (LRSD) of light fields, enabling simultaneous high-contrast imaging of absorption and scattering and significantly improving imaging performance.

The Role of Hemispheric Sensory Shifts: Impacts on Stretch Reflex and Motor Plasticity Post-Stroke.

Previous studies have found that post-stroke motor impairments are associated with damage to the lesioned corticospinal tract and the hyperexcitability of the cortico-reticulospinal tract at the hemisphere opposite to the lesion side, i.e., the contralesional hemisphere.

Au-incorporated metal-organic frameworks nanozymes for thioreduction and glutathione depletion-mediated efficient photoimmunotherapy.

Tumor therapy has historically been a global research focus, with phototherapy garnered significant attention as a innovative treatment modality. However, the antioxidant defense system in the tumor microenvironment, characterized by excessive glutathione (GSH) and thiol-containing proteins, often limits the effectiveness of photodynamic therapy. In this study, we report the development of a new multifunctional integrated nanozyme with thioredoxin reductase-oxidase (TrxRox) and GSH-oxidase (GSHox)-like activities.

Axillary lymph node management strategies in cN + breast cancer patients after neoadjuvant chemotherapy.

With the widespread use of neoadjuvant chemotherapy (NAC), the optimal management strategy for axillary lymph nodes following chemotherapy has become a hot topic of discussion. For patients with clinically positive axillary lymph nodes (cN +) (defined as axillary lymph nodes confirmed positive by pathology before NAC), axillary lymph node dissection (ALND) remains the current standard treatment. However, there is still no consensus on whether sentinel lymph node biopsy (SLNB) and other local axillary treatments following NAC can safely replace ALND to reduce injury and complications.

Universal and extensible language-vision models for organ segmentation and tumor detection from abdominal computed tomography.

The advancement of artificial intelligence (AI) for organ segmentation and tumor detection is propelled by the growing availability of computed tomography (CT) datasets with detailed, per-voxel annotations. However, these AI models often struggle with flexibility for partially annotated datasets and extensibility for new classes due to limitations in the one-hot encoding, architectural design, and learning scheme. To overcome these limitations, we propose a universal, extensible framework enabling a single model, termed Universal Model, to deal with multiple public datasets and adapt to new classes (e.
