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 ...
Hypoprolactinemic rats under conditions of constant darkness or constant light. Effects on the sleep-wake cycle, cerebral temperature and sulfatoxymelatonin levels
(Elsevier B.V., 1999-07-24)
In genetic hypoprolactinemic rats under light-dark (LD) conditions, the circadian rhythms of slow-wave (SWS) and paradoxical (PS) sleep display an alteration of their phase relationship. the aim of our study was to investigate ...
Melatonin administration modifies circadian motor activity under constant light depending on the lighting conditions during suckling
(Taylor & Francis, 2015-07)
Early lighting conditions have been described to produce long-term effects on circadian behavior, which may also influence the response to agents acting on the circadian system. It has been suggested that melatonin (MEL) ...
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. ...
Oxidative stress in retinal degeneration promoted by constant LED light
(Frontiers Media S.A., 2019-01)
Light pollution by artificial light, might accelerate retinal diseases and circadian asynchrony. The excess of light exposure is a growing problem in societies, so studies on the consequences of long-term exposure to low ...
Photopolymerization devises light intensity relation with physical translucid barriers use
(2020)
Abstract:
Nowadays, the use of halogen or light emission diode (LED) devices in dental attention is constant for almost any oral treatment. The need of providing an adequate light intensity for a correct photopolymerization ...
Measurement of phase and amplitude modulations in Sb-Based Films
(2009-11-23)
In this work we studied the changes of the optical constants of films in the binary system Sb2O3-Sb2S3 induced by light in the VIS-UV. The measurements were performed before and after homogeneous irradiation of the films ...
