White Light–Emitting Diodes (LEDs) at Domestic Lighting Levels and Retinal Injury in a Rat Model
Environmental Health Perspectives, 2013 Background: Light-emitting diodes (LEDs) deliver higher levels of blue light to the retina than do conventional domestic light sources. Chronic exposure to high-intensity light (2,000–10,000 lux) has previously been found to result in light-induced ...

INFLUENCE OF LIGHT EMITTING DIODE (LED) ON MICROALGAE
Journal of Chemical Engineering and Industrial Biotechnology, 2020 There are 150,000 microalgae species. Scientists identified and classified 30,000 species. Only 10–15 species are utilised and studied for wastewater treatment, biogas upgrading, biomass production, and lipid content. LED can raise microalgae performance to the highest.

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
