Effect of blue light on Albino Rat's retina [PDF]

Minia Journal of Medical Research
:Background: Blue light has a very dangerous and harmful effect on the retina. Blue light is part of electromagnetic radiation and has wavelength in-between 400: 500 nm.

Potential dosemeter for quantifying biologically effective blue light exposures [PDF]

, 2011
This paper reports on the development of a blue light (VISBL) dosimeter. The VISBL dosimeter is based on the combination of polysulfone and phenothiazine as a potential VISBL dosimeter for population studies of exposures related to the blue light hazard.

Supplemental Blue Light Frequencies Improve Ripening and Nutritional Qualities of Tomato Fruits

Frontiers in Plant Science, 2022
Tomatoes (Solanum lycopersicum L. Micro-Tom) were grown in a plastic greenhouse. When plants anthesis, the 100 μmol m–2 s–1 blue light-emitting diode (LED) light (430 ± 10 nm) was supplemented from 6:00 to 18:00.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Light-dependent magnetoreception in birds : increasing intensity of monochromatic light changes the nature of the response [PDF]

, 2007
Background The Radical Pair model proposes that magnetoreception is a light-dependent process. Under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show orientation in their migratory direction.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Blue light pollution induces dry eye by damaging conjunctival stem cells through cAMP-PKA-Pax6 signaling pathway

Ecotoxicology and Environmental Safety
Purpose: Blue light exposure constitutes a risk factor for dry eye. The research explores the influence of conjunctival stem cells (CjSCs) by blue light, elucidating the pathogenesis of blue light-induced dry eye.

Effects of Light Wavelength on Daughter Cladode Growth and Quality in Edible Cactus Nopalea cochenillifera Cultured in a Plant Factory with Artificial Light

Journal of Horticultural Research, 2018
In this study, we investigated the effects of different-colored light-emitting diodes (LEDs) on the growth and quality of daughter cladodes of the edible cactus Nopalea cochenillifera.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
