An Experimental Study on the Protective Effect of Memantine in Noise‐Induced Hearing Loss

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective This study examined the potential protective effects of memantine, an N‐methyl‐D‐aspartate (NMDA) receptor antagonist, against acoustic trauma (AT) in guinea pigs, using electrophysiological and histopathological analyses. Methods Thirty guinea pigs with normal hearing were divided into six groups (n = 5 per group): Group 1 (control),

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

Journal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Multisystem Mucosal Morbidity in Recessive Dystrophic Epidermolysis Bullosa Inversa

Pediatric Dermatology, EarlyView.
ABSTRACT Background/Objectives Recessive dystrophic epidermolysis bullosa inversa (RDEB‐I) is a rare subtype of dystrophic epidermolysis bullosa (EB) characterized by intertriginous cutaneous involvement and frequent mucosal disease. Although mucosal involvement is recognized in RDEB‐I, its cumulative clinical burden remains poorly defined.
