Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Skull base reconstruction using hydroxyapatite and nasoseptal flap versus nasoseptal flap alone: meta-analysis and systematic review

open access: yesScientific Reports
Endoscopic endonasal surgery (EES) is widely employed for interventions in skull base. Despite advancements in surgical techniques, cerebrospinal fluid (CSF) leakage remains a significant concern.

Functional Reconstruction of Temporomandibular Joint after Resection of Pigmented Villonodular Synovitis with Extension to Infratemporal Fossa and Skull Base: A Case Report

open access: yesThe Surgery Journal, 2016
Introduction Pigmented villonodular synovitis (PVNS) is a benign but aggressive lesion arising from sinovia. The temporomandibular joint (TMJ) is hardly ever involved.

Prickle4 Drives Microenvironmental Remodeling and Resistance to Parp Inhibition in IDH‐Mutant Glioma

open access: yesAdvanced Science, EarlyView.
IDH‐mutant gliomas exhibit sensitivity to PARP inhibitors (PARPi) owing to oncometabolite 2‐HG‐induced DNA repair defects. PARPi treatment induces resistance by upregulating Prickle4, which promotes VEGF‐driven angiogenesis. Combining PARPi veliparib with anti‐angiogenic lenvatinib blocks this pathway, causing tumor regression and prolonged survival in

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

open access: yesAdvanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

Intracranial chordoma presenting as acute hemorrhage in a child: Case report and literature review [PDF]

open access: yes, 2015
BACKGROUND: Chordomas are rare, slow-growing malignant neoplasms derived from remnants of the embryological notochord. Pediatric cases comprise only 5% of all chordomas, but more than half of the reported pediatric chordomas are intracranial.

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

open access: yesAdvanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...
