Intense Light Therapy Before Surgery Could Help Protect the Heart

Facebook X LinkedIn Email
Researchers at the University of Colorado Anschutz Medical Campus have found that intense light amplifies a specific gene — Period 2 (PER2) — that makes the metabolism of mice and humans more oxygen-efficient. This amplification could offer protection against injury to the heart muscle if the light therapy were given before high-risk cardiac and noncardiac surgery. The scientists sought to develop a cardio-protective strategy using light to target and manipulate the function of the PER2 gene, which is expressed in a circadian pattern in the part of the brain that controls...Read full article

    photobiomodulation
    A light therapy that utilizes nonionizing light sources, including lasers, LEDs, and broadband light, in the visible and infrared spectrum. It is a nonthermal process involving endogenous chromophores eliciting photophysical (i.e., linear and nonlinear) and photochemical events at various biological scales. This process results in beneficial therapeutic outcomes, including but not limited to the alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue...
