Speech perception, real-ear measurements and self-perceived hearing impairment after remote and face-to-face programming of hearing aids: A randomized single-blind agreement study.

Introduction: Current literature does not provide strong evidence that remote programming of hearing aids is effective, despite its increasing use by audiologists. We tested speech perception outcomes, real-ear insertion gain, and changes in self-perceived hearing impairment after face-to-face and remote programming of hearing aids in a randomized multicentre, single-blind crossover study.

Methods: Adult experienced hearing aid users were enrolled during routine follow-up visits to audiology clinics.

Evaluation of otoscopy simulation as a training tool for real-time remote otoscopy.

Objective: Teleotoscopy requires the assistance of telehealth facilitators; but their training requirements remain to be determined. We evaluated the use of an otoscopy simulator to train facilitators to remote otoscopies sent via the Internet using a teleaudiology platform.

Design: Neurotologists experts were asked to identify images using the otoscopy simulator and to perform an identification task of significant anatomical landmarks.

Distribution of transposable elements in Drosophila species.

We present a global analysis of the distribution of 43 transposable elements (TEs) in 228 species of the Drosophila genus from our data and data from the literature. Data on chromosome localization come from in situ hybridization and presence/absence of the elements from southern analyses. This analysis shows great differences between TE distributions, even among closely related species.

Polymorphism in structure of the retrotransposable element 412 in Drosophila simulans and D. melanogaster populations.

The structure of the 412 retrotransposable element was investigated in various natural populations of D. melanogaster and D. simulans by a restriction enzyme analysis.

Distribution of the retrotransposable element 412 in Drosophila species.

Copy numbers of sequences homologous to the Drosophila melanogaster retrotransposable element 412, their distribution between the chromosome arms and the chromocenter, and whether they contain full-size copies were analyzed for 55 species of the Drosophila genus. Element 412 insertion sites were detected on the chromosome arms of D. melanogaster, Drosophila simulans, and a few species of the obscura group, but the chromocenter was labeled in almost all species.
