Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Malignant craniopharyngiomas: Institutional experience and literature review

Brain Pathology, EarlyView.
We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

Brain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

Comparison of Piezoelectric and High‐Speed Drills for Frontal Beak Osteotomy in Endoscopic Sinus Surgery—Exploratory Study

Clinical Otolaryngology, EarlyView.
ABSTRACT Introduction Frontal beak reduction is a critical and challenging step in endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Traditional high‐speed drills can risk thermal injury and soft tissue trauma, whereas piezoelectric surgery uses ultrasonic vibrations for selective bone cutting and may improve surgical precision.
