An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

Advanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Systematic Analysis of Cerebrospinal Fluid Leak after Endoscopic Skull Base Surgery: Tumor Location, Closure Method, and Pathology.

, 2011
Objective: Endoscope-assisted cranial base surgery provides a direct, minimally invasive alternative to traditional transcranial approaches. One of the greatest challenges of endoscopic anterior base surgery is avoidance of postoperative CSF leaks, which
