Adenosine deaminase acting on RNA (ADAR) catalyzes the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) substrates. Inosine pairs preferentially with cytidine, as opposed to uridine; therefore, ADAR editing alters the sequence and base pairing properties of both protein-coding and non-coding RNA. Editing can directly alter the(More)
To examine the functional connectivity of the primary and supplementary motor areas (SMA) in glioma patients using resting-state functional MRI (rfMRI). To correlate rfMRI data with tumor characteristics and clinical information to characterize functional reorganization of resting-state networks (RSN) and the limitations of this method. This study was IRB(More)
BACKGROUND Surgical-site infections (SSIs) are an important cause of morbidity and mortality in neurosurgical patients. Topical antibiotics are one potential method to reduce the incidence of these infections. OBJECTIVE To examine the efficacy of topical vancomycin applied within the wound during craniotomy in a large prospective cohort study at a major(More)
An abundance of evidence points to the role of a presupplementary motor area (pre-SMA) in human language. This study explores the pre-SMA resting state connectivity network and the nature of its connections to known language areas. We tested the hypothesis that by seeding the pre-SMA, one would be able to establish language laterality to known cortical and(More)
Neonatal brachial plexus avulsion injury (BPAI) commonly occurs as a consequence of birth trauma and can result in lifetime morbidity; however, little is known regarding the evolving neuropathological processes it induces. In particular, mechanical forces during BPAI can concomittantly damage the spinal cord and may contribute to outcome. Here, we describe(More)
PURPOSE While frequently prescribed to patients following fixation for spine trauma, the utility of spinal orthoses during the post-operative period is poorly described in the literature. In this study, we calculated rates of reoperation and performed a decision analysis to determine the utility of bracing following pedicle screw fixation for thoracic and(More)
BACKGROUND Deep brain stimulation (DBS) has emerged as a safe and efficacious surgical intervention for several movement disorders; however, the 30-day all-cause readmission rate associated with this procedure has not previously been documented. OBJECT To perform a retrospective cohort study to estimate the 30-day all-cause readmission rate associated(More)
