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.

Technique and setup for diagnostics of p-n junction–package thermal resistance in high-power gallium nitride LEDs [PDF]

, 2012
We present a setup and procedure of studying p-n junction–package thermal resistance in high-power light-emitting diodes (LEDs) from their thermal relaxation. A set of LEDs mounted on a metal-core printed circuit board (MCPCB) were studied.

Retinal damage induced by commercial light emitting diodes (LEDs) [PDF]

Free Radical Biology and Medicine, 2015
Spectra of "white LEDs" are characterized by an intense emission in the blue region of the visible spectrum, absent in daylight spectra. This blue component and the high intensity of emission are the main sources of concern about the health risks of LEDs with respect to their toxicity to the eye and the retina. The aim of our study was to elucidate the

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

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

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,
