The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
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 light exposure on functional compounds of monovarietal extra virgin olive oils and oil mixes during early storage as evaluated by fluorescence spectra
(Springer, 2019-08)
The oxidation of antioxidants in bottled extra virgin olive oil (EVOO), especially vitamin E and chlorophyll, can affect the quality of the product. However, the effect of light exposure on these functional compounds and ...
Neonatal exposure to constant light prevents anhedonia-like behavior induced by constant light exposure in adulthood
(Elsevier B.V., 2011-09-12)
Depressive episodes are associated with disturbances in circadian rhythms, and constant illumination has been reported to induce depressive-like behavior in rodents. Rats kept in constant darkness express the endogenous ...
Non-visual photopigments effects of constant light-emitting diode light exposure on the inner retina of Wistar rats
(Frontiers Media S.A., 2017-08)
The retina is part of the central nervous system specially adapted to capture light photons and transmit this information to the brain through photosensitive retinal cells involved in visual and non-visual activities. ...
Telling the Seasons Underground: The Circadian Clock and Ambient Temperature Shape Light Exposure and Photoperiodism in a Subterranean Rodent
(Frontiers Media, 2021-10-01)
Living organisms anticipate the seasons by tracking the proportion of light and darkness hours within a day—photoperiod. The limits of photoperiod measurement can be investigated in the subterranean rodents tuco-tucos ...
