Research progress of neurovascular units involved in ischemic stroke

open access: yesIbrain, EarlyView.
The brain receives less blood when an ischemic stroke develops, which damages neurons and leads to an increased release of Pro‐inflammatory mediators that activate neurovascular unit (NVU). When the tight junctions are broken and the basement membrane is disrupted by matrix metalloproteinases produced by active endothelial and pericellular cells ...

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

open access: yesIbrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Ultrasmall Superparamagnetic Iron Oxide Nanoparticles as Positive Contrast Agents in Low‐Field Magnetic Resonance Imaging

open access: yesiRADIOLOGY, EarlyView.
Ultrasmall superparamagnetic iron oxide nanoparticles emerge as promising positive contrast agents for low‐field MRI. Unlike larger SPIONs, these particles exhibit enhanced T1 relaxivity through rapid magnetic fluctuations and surface spin canting. Their biocompatibility, renal clearance pathway, and bright contrast generation offer safer alternatives ...
