Onyx dilution reduces time to resolution of chronic subdural hematomas after middle meningeal artery embolization.

Background: The benefit of distal embolite penetration for middle meningeal artery (MMA) embolization in chronic subdural hematomas (cSDH) remains controversial.

Objective: To compare the use of diluted Onyx with undiluted Onyx in the management of cSDH.

Methods: This is a retrospective study of patients with cSDH who underwent MMA embolization using Onyx 18 at our institution.

Exercise and Recovery Following Mild-to-Moderate Traumatic Brain Injury in the Community Setting.

Introduction The recommendations on return to exercise post-traumatic brain injury (TBI) remain debatable. As recent as 10 years ago, the conventional recovery modality for a mild TBI was to reduce neurostimulating activity and encourage rest until the symptoms subsided. However, emerging literature has challenged this notion, stating that returning to exercise early in the course of mild TBI recovery may be beneficial to the recovery timeline.

Diaryl triazenes inhibit cytochrome P450 1A1 and 1B1 more strongly than aryl morpholino triazenes.

Several diaryl triazene derivatives were synthesized and tested for their ability to inhibit cytochrome P450 1A1 and 1B1 as a potential means to prevent and treat cancer. These compounds are more planar than their conformational flexible aryl morpholino triazene counterparts that were previously shown to inhibit the above enzymes. As a result, the diaryl triazenes are more likely to exhibit increased binding to the enzyme active sites and inhibit these enzymes more strongly than the aryl morpholino triazenes.
