A Look "Inside" the Sport of Wrestling: Examination of Head Acceleration Events and Mechanisms in Female High-School Wrestlers Using Instrumented Mouthguards.

Purpose: To characterize true-positive head accelerations events (HAEs) captured with instrumented mouthguards (iMGs) in high-school female wrestlers using video-verification during matches and to measure players' perceptions of iMG use.

Methods: Thirty female high-school wrestlers (ages 16.4 ± 0.

Fabrication, biodegradation behavior and cytotoxicity of Mg-nanodiamond composites for implant application.

Mg-based biodegradable implants offer several advantages over their non-degradable or degradable polymeric counterparts used today. However, the low corrosion resistance of Mg in physiologic environment remained as concerns. In this research, nanodiamond (ND) was uniformly dispersed in Mg matrix to induce a protective layer on Mg surface during corrosion.
