Unitary ototoxic gentamicin exposure may not disrupt the function of cochlear outer hair cells in mice.

Background: Previous study showed that mild ototoxic exposure could induce a reversible hearing impairment, and the loss and secondary incomplete recovery of cochlear ribbon synapses could be responsible for the hearing loss. However, it remains unclear whether cochlear outer hair cells' (OHCs) functions are affected.

Objective: To verify whether the function of OHCs are also affected significantly after the ototoxic exposure.

Association between vitamin D and development of otitis media: A PRISMA-compliant meta-analysis and systematic review.

Background: Nutrients related to serum vitamin D level were previously shown to be significantly associated with the risk of many chronic diseases. This study aimed to assess potential relationships between serum vitamin D level and otitis media (OM) risk.

Methods: PubMed, EMBASE, and Cochrane Library databases were searched till Aug 18, 2015 for studies of quantitative OM risk estimates in relation to serum vitamin D level.

MicroRNA-126 modulates the tumor microenvironment by targeting calmodulin-regulated spectrin-associated protein 1 (Camsap1).

Plasma miRNAs have been reported as biomarkers for various diseases. In this study, we investigated whether plasma concentrations of miR-126 may be useful as biomarkers for laryngeal squamous cell carcinoma (LSCC). We examined the function and mechanism of miR-126 in LSCC by using cell biology and molecular pathology techniques such as western blotting, quantitative PCR, IHC and IF.
