Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Evaluating the effect of caudal epidural block on optic nerve sheath diameter in pediatric patients: randomized controlled study

BMC Anesthesiology
Introduction Caudal epidural block is a widely performed procedure for postoperative pain control of pediatric patients. As the local anesthetic acts by spreading cranially after caudal block, it may lead to several effects on the cerebrospinal fluid and

Optic Nerve Sonography in the Diagnostic Evaluation of Pseudopapilledema and Raised Intracranial Pressure: A Cross-Sectional Study

Neurology Research International, 2015
Introduction. Differentiating pseudopapilledema from papilledema which is optic disk edema and a result of increased ICP (intracranial pressure) is important and can be done with noninvasive methods like orbital ultrasound examination. Method. This was a

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Idiopathic Intracranial Hypertension Associated With Transverse Sinus Giant Arachnoid Granulation Successfully Treated by Endovascular Stenting

Neurology and Clinical Neuroscience, EarlyView.
ABSTRACT The incidence of Idiopathic intracranial hypertension (IIH), defined as increased intracranial pressure of unknown origin, has been reported to be very low in Japan. A 42‐year‐old Japanese woman was admitted to our hospital with headache, blurred vision, and tinnitus.

Three Types of Optic Disc Edema in Optic Nerve Sheath Meningioma

, 2021
ONSM (optic nerve sheath meningioma) accounts for approximately 2% of all orbital tumors and represents around 1-2% of all meningiomas. Classical triad of progressive visual loss, optic nerve atrophy, and presence of optociliary shunt vessels is ...

Tailoring MXene Flake Morphology via Aerosol Jet Printing for Biological and Strain Sensor Applications

Small, EarlyView.
Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Tailoring Zn2+ Solvation for Dendrite‐Free and High‐Efficiency Aqueous Zinc Batteries

Small, EarlyView.
A ternary water–methanol–dimethyl sulfoxide hybrid electrolyte reconstructs the Zn2+ solvation sheath by reducing free water activity and promoting coordinated solvent interactions. The regulated interfacial chemistry suppresses parasitic reactions and enables dense, uniform zinc deposition, resulting in enhanced reversibility and long‐term cycling ...
