-Derived Collagen Peptides Mixed with Extracts Exhibit Anti-Photoaging Activities during Exposure to UV Irradiation, and Antibacterial Properties.

, a species of starfish and cause of concern in the aquaculture industry, was recently identified as a source of non-toxic and highly water-soluble collagen peptides. In this study, we investigated the antioxidant and anti-photoaging functions of compounds formulated using collagen peptides from extracts of and (AH). Our results showed that AH compounds have various skin protective functions, including antioxidant effects, determined by measuring the scavenging activity of 2,2-diphenyl-1-picrylhydrazyl radicals, as well as anti-melanogenic effects, determined by measuring tyrosinase inhibition activity.

Is There a Relationship Between Bone Quality and Hearing Level?

Objectives: This study evaluated the correlation between skull bone attenuation on temporal bone computed tomography (CT) and bone mineral density (BMD) of the central skeleton on dual-energy x-ray absorptiometry (DXA) and the correlation between bone quality and hearing level.

Study Design: Retrospective observational.

Setting: Tertiary referral center.
