Circadian time-dependent effects of fencamfamine on inhibition of dopamine uptake and release in rat striatal slices
(1997-05-01)
Fencamfamine (FCF) is a central stimulant that facilitates central dopaminergic transmission through inhibition of dopamine uptake and enhanced release of the transmitter. We evaluated the changes in the inhibition of ...
Calcineurin signaling in the heart: The importance of time and place
(Academic Press, 2017)
© 2016 Elsevier LtdThe calcium-activated protein phosphatase, calcineurin, lies at the intersection of protein phosphorylation and calcium signaling cascades, where it provides an essential nodal point for coordination ...
Circadian pattern of Bothrops moojeni in captivity (Serpentes: Viperidae)
(Centro de Estudos de Venenos e Animais Peçonhentos - CEVAP, Universidade Estadual Paulista - UNESPBOTUCATU, 2012)
Members of the subfamily Crotalinae are considered to be essentially nocturnal and most of the data about these snakes have been collected from the field. Information on how nutritional status affects the movement rate and ...
Relógio alimentar: mecanismo de sincronização circadiana por ciclos de alimentação
(Universidade Federal do Rio Grande do NorteBrasilUFRNCiências Biológicas, 2007-12-06)
Food is important for all animal species. Its temporal availability seems to be a relevant signal for organization of behavioral and physiological parameters. When food is restricted for a few hours a day, rats and mice ...
The axon-guidance roundabout gene alters the pace of the Drosophila circadian clock
(Wiley Blackwell Publishing, Inc, 2008-01)
Great efforts have been directed to the dissection of the cell-autonomous circadian oscillator in Drosophila. However, less information is available regarding how this oscillator controls rhythmic rest-activity cycles. We ...
Tobacco hairy root's peroxidases are rhythmically controlled by phenol exposure
(Elsevier Science Inc., 2021-09)
Plants like almost all living organisms, have developed a biological clock or circadian clock (CC) capable of synchronizing and adjusting various metabolic and physiological processes at certain times of the day and in a ...
Seasonal Variation of Temporal Niche in Wild Owl Monkeys (Aotus azarai azarai) of the Argentinean Chaco: A Matter of Masking?
(Taylor & Francis, 2012-07)
Among the more than 40 genera of anthropoid primates (monkeys, apes, and humans), only the South American owl monkeys, genus Aotus, are nocturnal. However, the southernmostly distributed species, Aotus azarai azarai, of ...
Aging disrupts the temporal organization of antioxidant defenses in the heart of male rats and phase shifts circadian rhythms of systolic blood pressure
(Springer, 2021-12)
Aging is one of the main risk factors for cardiovascular diseases, and oxidative stress is a key element responsible for the development of age-related pathologies. In addition, the alteration of circadian rhythms also ...
Circadian Regulation and Clock-Controlled Mechanisms of Glycerophospholipid Metabolism from Neuronal Cells and Tissues to Fibroblasts
(Humana Press, 2021-10-26)
Along evolution, living organisms developed a precise timekeeping system, circadian clocks, to adapt life to the 24-h light/dark cycle and temporally regulate physiology and behavior. The transcriptional molecular circadian ...
Daily activity pattern of Heleobia parchappii (Gastropoda: Hydrobiidae) under laboratory conditions
(Oikos Publishers, Inc, 2006-12)
Crawling, floating and burrowing abilities of the Argentine freshwater mudsnail, Heleobia parchappii (d?Orbigny 1835), were experimentally analyzed. Floating showed a cyclic circadian pattern, young snails using floatation ...
