Circadian Pattern of Wheel-Running Activity of a South American Subterranean Rodent (Ctenomys cf knightii)
(TAYLOR & FRANCIS INC, 2009)
Circadian rhythms are regarded as essentially ubiquitous features of animal behavior and are thought to confer important adaptive advantages. However, although circadian systems of rodents have been among the most extensively ...
Experimental assessment of the network properties of the Drosophila circadian clock
(Wiley, 2015-04)
Circadian rhythms are conserved across kingdoms and coordinate physiology and behavior for appropriate time-keeping. The neuronal populations that govern circadian rhythms are described in many animal models, and the current ...
Immunosuppressant calcineurin inhibitors phase shift circadian rhythms and inhibit circadian responses to light
(Elsevier, 2008-10)
PP2B is a Ca2+/calmodulin-dependent protein phosphatase that is ubiquitously expressed in mammals. Among other actions, it is an effector mechanism in NMDA-mediated glutamate neurotransmission as well as a regulator of ...
Circadian rhythms and post-transcriptional regulation in higher plants
(Frontiers, 2015-06-12)
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps. One of the ...
Role of astrocytes in the immune-circadian signaling
(IOS Press, 2013-10)
The mammalian circadian system controls biological rhythms by means of a central biological clock located in the suprachiasmatic nuclei (SCN) as well as diverse peripheral oscillators located throughout the body. Besides ...
Longitudinal study of the spectral composition of behavioral rhythms in the rat
(Taylor & Francis Ltd, 2005-02-01)
Four. male Wistar rats were housed in pairs of siblings, on LD 12:12h and 22 degrees C + 2 degrees C. Food and water were provided ad libitum. Behavior was videotaped from the 1st to the 3rd month of life. In each age-bracket ...
Long-term oscillations in the sleep/wake cycle of infants
(ELSEVIER SCIENCE BV, 2009)
The development of circadian sleep-wakefulness rhythm was investigated by a longitudinal study of six normal infants. We propose an entropy based measure for the sleep/wake cycle fragmentation. Our results confirm that the ...
Modeling the Emergence of Circadian Rhythms in a Clock Neuron Network
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
Circadian rhythms in pacemaker cells persist for weeks in constant darkness, while in other types of cells the molecular oscillations that underlie circadian rhythms damp rapidly under the same conditions. Although much ...
Daily and annual circarhythms activity in the South American sea lion Otaria flavescens (Carnivora: Otariidae) at the central zone of Chile
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2001)
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 ...
