Direct oral anticoagulants are the primary stroke prevention option in patients with atrial fibrillation. Anticoagulant use before stroke, however, might inhibit clinician comfort with thrombolysis if a stroke does occur. Resuming anticoagulants after ischemic stroke is also problematic for fear of hemorrhage.

The neurovascular unit (NVU) includes multiple different cell types, including neurons, astrocytes, endothelial cells, and pericytes, which respond to insults on very different time or dose scales. We defined differential vulnerability among these cell types, using response to two different insults: oxygen-glucose deprivation (OGD) and thrombin-mediated cytotoxicity. We found that neurons are most vulnerable, followed by endothelial cells and astrocytes.

Epiretinal membranes (ERMs) are the result of fibro-cellular proliferation that cause distortion and impairment of central vision. We hypothesized that select microRNAs (miRs) regulate retinal fibro-proliferation and ERM formation. Following IRB approval, a pilot study was performed in patients presenting for retina surgery with and without clinical ERMs.

Purpose: To describe a minimally invasive surgical technique using AlloDerm or dermis-fat grafts for lower eyelid retraction.

Methods: A retrospective review of all patients undergoing lower eyelid retraction surgery via a minimal invasive, "en-glove" technique from 2005 through 2009. Charts were reviewed for the type of graft (AlloDerm or dermis-fat) used, the etiology of lower eyelid retraction, and the follow-up time.
