In Vivo Multimodal Imaging of Drusenoid Lesions in Rhesus Macaques. [PDF]

open access: yes, 2017
Nonhuman primates are the only mammals to possess a true macula similar to humans, and spontaneously develop drusenoid lesions which are hallmarks of age-related macular degeneration (AMD).

Integrative genomic and spatial transcriptomic analysis elucidates the oligodendrocyte‐mediated etiology of epileptic cortical thinning

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Focal epilepsy is characterized by progressive cortical thinning, particularly within limbic structures; however, whether this atrophy reflects acquired seizure‐induced damage or shared genetic predisposition remains unresolved. Methods We integrated genome‐wide association study (GWAS) summary statistics from the ILAE Consortium ...

Quantifying Dehydration Effects of Porcine Vocal Fold Attenuation With Optical Coherence Tomography

open access: yesThe Laryngoscope, EarlyView.
The purpose of this study is to use optical coherence tomography (OCT) to characterize the effect of dehydration on the optical attenuation coefficient of porcine vocal fold (VF) tissue. The optical attenuation coefficient tissue decreased linearly with dehydration, dropping by approximately 0.08 mm−1 for every 1% increase in mass loss.

Ex Vivo Evaluation of Poly(Solketal Acrylate) Nanoparticles for Intravitreal Drug Delivery to the Posterior Eye Segment

open access: yesMacromolecular Rapid Communications, EarlyView.
Nile Red‐loaded poly(solketal acrylate) nanoparticles enable fluorescence tracking and exhibit nontoxic profiles in retinal cells. Enhanced cellular uptake and deep retinal penetration after intravitreal injection highlight their excellent potential for targeted ocular drug delivery to the posterior segment of the eye.
