Photobiomodulation with 808-nm diode laser light promotes wound healing of human endothelial cells through increased reactive oxygen species production stimulating mitochondrial oxidative phosphorylation

A study published in Lasers in Medical Science (2019) investigated the effects of 808-nm diode laser photobiomodulation (PBM) on wound healing in human endothelial cells. The results showed that PBM increased the production of reactive oxygen species (ROS), which in turn stimulated mitochondrial oxidative phosphorylation, boosting ATP production and promoting

Visible red light does not induce DNA damage in human dermal fibroblasts

This in vitro study investigated the potential DNA-damaging effects of visible red light (RL) exposure on human dermal fibroblasts (HDFs), given its growing use in dermatology for acne, psoriasis, and wound healing. The study found that RL at fluences of 320 J/cm², 640 J/cm², and 1280 J/cm² (wavelength 633 ± 6 nm) did

Alpha lipoic acid inhibits proliferation and epithelial mesenchymal transition of thyroid cancer cells

This in vitro study investigated the effects of alpha-lipoic acid (ALA) on thyroid cancer cell proliferation, migration, and invasion. Using four human thyroid cancer cell lines (BCPAP, HTH-83, CAL-62, and FTC-133), researchers found that ALA significantly suppressed cancer cell proliferation by activating the AMPK pathway, leading to the downregulation of
