Pressure Pulses Generated by Wire‐Guided Discharges in Water

High Voltage, EarlyView.
ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

Patent Ductus Arteriosus Persistence and Neurodevelopmental Outcomes: A Restrictive Treatment Approach Does Not Compromise Neurological Development

Acta Paediatrica, EarlyView.
ABSTRACT Aim Optimal treatment strategies for patent ductus arteriosus (PDA) and their impact on neurodevelopmental outcomes remain controversial. This study investigates the influence of PDA duration on neurodevelopment under a restrictive treatment approach.

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.

Neonates born at term with periventricular haemorrhagic infarction: Risk factors and clinical presentation

Developmental Medicine &Child Neurology, EarlyView.
This case series describes infants born near term with periventricular hemorrhagic infarction (PVHI), highlighting seizures as a common early symptom. Neonatal complications during delivery and pro‐thrombotic genetic mutations were slightly more common. MRI‐classified involvement was predominantly in the caudate vein territory.

Synaptic ultrastructural alterations in human focal cortical dysplasia: Insights from volume electron microscopy

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a developmental malformation of the cerebral cortex and a leading cause of drug‐resistant epilepsy in children and young adults. Disruption of the excitation–inhibition (E–I) balance is a hallmark of neuronal hyperexcitability in FCD, yet the underlying synaptic ultrastructural changes remain poorly ...
