A Dynamic DNA Nano‐Antioxidant Targeting Galectin‐3 Attenuates Liver Fibrosis via Reducing Macrophage Oxidative Stress

Advanced Science, EarlyView.
This study developed a dynamic DNA nano‐antioxidant (DDN) for Galectin‐3 siRNA delivery, specifically targeting hepatic macrophages to suppress ROS‐driven fibrosis. DDN enhanced hepatic accumulation, restored NRF2 signaling, and attenuated oxidative stress, collagen deposition, and fibrotic progression in a CCl4‐induced cirrhosis model, demonstrating ...

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

A mutate-and-map protocol for inferring base pairs in structured RNA

, 2013
Chemical mapping is a widespread technique for structural analysis of nucleic acids in which a molecule's reactivity to different probes is quantified at single-nucleotide resolution and used to constrain structural modeling.

T1WI‐SWI Dual Modal Magnetic Resonance Nanoprobes for Accurate Diagnosis of Early Stage Alzheimer's Disease

Advanced Science, EarlyView.
We developed a smart MRI nanoprobe targeting BACE1 and Aβ plaques. It crosses the blood‐brain barrier. Upon encountering BACE1, the probe is cleaved, enabling T1WI imaging detection. Subsequent reaction with ONOO− induces probe aggregation, enhancing magnetic susceptibility for sensitive SWI imaging of Aβ plaques.

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

Advanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...
