The case for ceramic-on-polyethylene as the preferred bearing for a young adult hip replacement
The optimum choice of bearing surfaces in total hip arthroplasty, particularly in the younger and more active patient, remains controversial. Despite several studies demonstrating good long-term results for the...
Two-year outcomes of minimally invasive XEN Gel Stent implantation in primary open-angle and pseudoexfoliation glaucoma.
PURPOSE: The aim of this study was to evaluate the efficacy of XEN® Gel Stent implantation in the treatment of primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (XFG) regarding the reduction of intraocular...

Effects of the relative timing of opposite-polarity pulses on loudness for cochlear implant listeners.
The symmetric biphasic pulses used in contemporary cochlear implants (CIs) consist of both cathodic and anodic currents, which may stimulate different sites on spiral ganglion neurons and, potentially, interact with each other....
