Role of digital subtraction angiography in acute cervical spinal cord ischemia.

Ascertaining the etiology of cervical spinal cord dysfunction presents a challenge to clinicians, as the list of differential diagnoses is extensive. Although compressive and inflammatory disorders are common and should be considered immediately, vascular causes are similarly important and acute. The overlap of clinical, magnetic resonance imaging, and cerebrospinal fluid features among the causes of myelopathies may lead to erroneous diagnoses.

Self-Recording of Eye Movements in Amyotrophic Lateral Sclerosis Patients Using a Smartphone Eye-Tracking App.

Introduction: Amyotrophic lateral sclerosis (ALS) can affect various eye movements, making eye tracking a potential means for disease monitoring. In this study, we evaluated the feasibility of ALS patients self-recording their eye movements using the "EyePhone," a smartphone eye-tracking application.

Methods: We prospectively enrolled ten participants and provided them with an iPhone equipped with the EyePhone app and a PowerPoint presentation with step-by-step recording instructions.

Unveiling the mechanism of deformation-induced supersaturation.

A Cu-6at%Ag cast alloy was deformed by means of high-pressure torsion to different applied strain levels until a steady-state regime is reached. The continuous structural refinement is attended by the successive dissolution of the Ag precipitates in the Cu matrix. The results show that the Ag regions need to fall below a phase size of ~ 5 nm to fully dissolve.

Vessel Wall Imaging Features of Spontaneous Intracranial Carotid Artery Dissection.

Background And Objectives: Intracranial dissection is an important cause of stroke often with nonspecific angiographic features. Vessel wall imaging (VWI) can detect dissections, but intracranial applications remain unvalidated by pathologic specimens. We sought to determine the ability of VWI to identify the rarely reported spontaneous intracranial carotid dissection (sICD) guided by postmortem validation.

Alternate Day Fasting Leads to Improved Post-Stroke Motor Recovery in Mice.

Background: Caloric restriction promotes neuroplasticity and recovery after neurological injury. In mice, we tested the hypothesis that caloric restriction can act post-stroke to enhance training-associated motor recovery.

Methods: Mice were trained to perform a skilled prehension task.
