DNA staining method based on formazan precipitation induced by blue light exposure
(Journal of Visualized Experiments, 2018)
DNA staining methods are very important for biomedical research. We designed a simple method that allows DNA visualization to the naked eye by the formation of a colored precipitate. It works by soaking the acrylamide or ...
Red Light Stimulates Feeding Motivation in Fish but Does Not Improve Growth
(2013-03-14)
Nile tilapia fish were individually reared under similar light levels for 8 weeks under five colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (~452 nm), green (~516 nm), yellow (~520 ...

Effect of Twice-Daily Blue Light Treatment on Matrix-Rich Biofilm Development
(Public Library Science, 2015-07-31)
Background The use of blue light has been proposed as a direct means of affecting local bacterial infections, however the use of blue light without a photosensitizer to prevent the biofilm development has not yet been ...
Environmental blue light prevents stress in the fish Nile tilapia
(Associação Brasileira de Divulgação Científica (ABRADIC), 2001-08-01)
The present study aimed to test the effects of blue, green or white light on the stress response of the Nile tilapia, Oreochromis niloticus (L.). Each color was tested on two groups of isolated adult Nile tilapia (8 ...

Evaluation of growth and motility in non-photosynthetic Azospirillum brasilense exposed to red, blue, and white light
(Springer, 2020-07)
Azospirillum brasilense is a non-photosynthetic rhizobacterium that promotes the growth of plants. In this work, we evaluated the effects of different light qualities on the growth, viability, and motility in combination ...
Low blue light enhances phototropism by releasing cryptochrome 1-mediated inhibition of PIF4 expression
(American Society of Plant Biologist, 2020-06)
Shade-avoiding plants, including Arabidopsis (Arabidopsis thaliana), display a number of growth responses, such as elongation of stem-like structures and repositioning of leaves, elicited by shade cues, including a reduction ...
Behavior of broilers reared under monochromatic and fluorescent light sources
(2016-01-01)
The study aimed to evaluate the behavior of broiler chickens reared in the blue and red light emitting diode (LED), using a fluorescent light as a control. The bird behaviors were recorded at 28, 35 and 42 d of grow-out ...
