Efficacy of 670 nm Light Therapy to Protect against Photoreceptor Cell Death Is Dependent on the Severity of Damage

Photobiomodulation at a wavelength of 670 nm has been shown to be effective in preventing photoreceptor cell death in the retina.We treated Sprague-Dawley (SD) rats with varying doses of 670 nm light (9; 18; 36; 90 J/cm2) before exposing them to different intensities of damaging white light (750; 1000; 1500 lux).670 nm light exhibited a biphasic re

Mechanical Evaluation of Polymer Composite Hip Protectors

Hip fractures often result in serious health implications, particularly in the geriatric population, and have been related to long-term morbidity and death.In most cases, these fractures are caused by impact loads in the area of the greater trochanter, which are produced in a fall.This work is aimed at developing hip protectors using composite mate
