Further studies confirmed that miRNA-224-5p indeed targets FXN, resulting in decreases in mRNA and protein levels. We also validated the ability of miRNA-10a-5p to bind and regulate the levels of brain-derived neurotrophic factor (BDNF), an important modulator of neuronal growth. We observed a significant decrease in the levels of miRNA-10a-5p and increase in the levels of BDNF upon correction of FRDA cells via zinc-finger nuclease (ZFN)-mediated excision of expanded GAA repeats. Our comprehensive transcriptome analyses identified miRNA-224-5p and miRNA-10a-5p as negative regulators of the FXN and BDNF expression, respectively. These results emphasize not only the importance of miRNAs in the pathogenesis of FRDA but also their potential as therapeutic targets for this disease.PURPOSE Videolaryngoscopy is widely believed to give a superior view to that obtained by direct laryngoscopy. Published literature suggests this benefit extends to both hyper-angulated and Macintosh-style videolaryngoscopes. Notwithstanding, our clinical experience shows that the videoscopic view with a Macintosh-style videolaryngoscope is often no different or only marginally better than the directly sighted peroral view. METHODS A human cadaver equivalence study was performed in which four experienced laryngoscopists obtained pre-assigned laryngeal views by direct sighting using the single-use Macintosh blades of the GlideScope® Spectrum™ (GS) DirectView Macintosh (DVM) and C-MAC®S videolaryngoscopes. Blinded to the laryngoscopist's view, two independent observers rated the videoscopic view presented on the proximal video monitor at the same time. Directly sighted and videoscopic views obtained by the laryngoscopist and video scorers were recorded on a visual analogue scale (VAS) for each device as the primary outcome measures and compared. RES
