Efeito da taxa de reforço e da concentração de açúcar na preferência por alimentos de composição tradicional ou light em universitários
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Psicologia - PPGPsi, 2015-03-13)
Food with high sugar concentration exhibits relation with impulsive eating behavior and obesity. This research investigated the effect of different rates of reinforcement and compositions of food, traditional or light, on ...
Assessing the cross-site and within-site response of potential production to atmospheric demand for water in Eucalyptus plantations
(2020-05-15)
Plant water deficits arise from low soil water and high atmospheric demand for water (expressed as vapor pressure deficit; VPD). Soil water and VPD often covary making it difficult to examine the effect of only VPD on ...
Drought-induced proline synthesis depends on root-to-shoot communication mediated by light perception
(2018-01-01)
Proline accumulation in roots and shoots is one of the most evident responses to environmental stresses such as drought, which is currently one of the main threats for agriculture. Based on this response, in this work, we ...
Adrenergic response patterns in vas deferens isolated from rats under diurnal rhythms - Influence of stress
(Elsevier B.V., 2005-08-26)
The aim of this study was to verify, by means of functional methods, whether the circadian rhythm changes adrenergic response patterns in the epididymal half of the vas deferens isolated from control rats as well as from ...

Light intensity regulates stoichiometry of benthic grazers through changes in the quality of stream periphyton
(University of Chicago Press, 2019-06)
In mountain streams, light is a key factor for primary production and primary producer nutrient stoichiometry, or the relative composition of carbon (C) compared to phosphorous (P) and nitrogen (N) in primary producers. ...
The LNK gene family: At the crossroad between light signaling and the circadian clock
(Molecular Diversity Preservation International, 2019-01)
Light signaling pathways interact with the circadian clock to help organisms synchronize physiological and developmental processes to periodic environmental cycles. The plant photoreceptors responsible for clock resetting ...
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 ...
Phytochrome A Antagonizes PHYTOCHROME INTERACTING FACTOR 1 to Prevent Over-Activation of Photomorphogenesis
(Oxford University Press, 2014-09)
Phytochrome A (phyA) is crucial to initiate the early steps of the transition between skoto- and photomorphogenesis upon light exposure and to complete this process under far-red light (typical of dense vegetation canopies). ...
Circadian Control of the Pupillary Light Responses in an Avian Model of Blindness, the GUCY1* Chickens
(Association For Research In Vision And Ophthalmology, 2015-01)
PURPOSE. The vertebrate inner retina has a subset of intrinsically photosensitive retinal ganglion cells (ipRGCs) that express the nonvisual photopigment melanopsin. The intrinsically photosensitive retinal ganglion cells ...
