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

open access: yesWorld 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),

Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

open access: yesIntegrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Impact of Chelators on FAC Following Interaction With NaOCl: A Focused Evidence Synthesis Based on a Systematic Search

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This systematic review following PRISMA guidelines evaluated the effects of endodontic chelators on free available chlorine (FAC) in sodium hypochlorite (NaOCl), with emphasis on the influence of concentration, contact time, temperature, and pH. Risk of bias was assessed using the Quality Assessment Tool for In Vitro Studies (QUIN).

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.
