Circadian rhythms of proliferation events in two mouse carcinomas
(Taylor & Francis Ltd, 2015-07)
We studied the index of DNA synthesis (DNAs) of two cellular carcinomas: the hepatocellular ES12a and the mammary TN60 of mice, throughout one circadian cycle. In the results, we observed that both tumors have circadian ...
Circadian pattern of wheel-running activity of a South American subterranean rodent (Ctenomys cf knightii)
(Taylor & Francis, 2009-01)
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 ...
Characterization of locomotor activity circadian rhythms in athymic nude mice
(BioMed Central, 2013-02)
BACKGROUND: The relation between circadian dysregulation and cancer incidence and progression has become a topic of major interest over the last decade. Also, circadian timing has gained attention regarding the use of ...
Circadian rhythms identified in Caenorhabditis elegans by in vivo long-term monitoring of a bioluminescent reporter
(National Academy of Sciences, 2016-11)
Circadian rhythms are based on endogenous clocks that allow organisms to adjust their physiology and behavior by entrainment to the solar day and, in turn, to select the optimal times for most biological variables. Diverse ...
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 ...
Magnetic fields, cancer and circadian rhythms: Hypotheses on the relevance of intermittence and cycling
(The Royal Society, 2019-11-04)
This commentary deals with the controversial relation between magnetic fields (MF) and cancer. Having been argued in a recent review article published in the Proceedings B that circadian rhythms could be a key to explain ...
Serotonin and circadian rhythms
(Pontifícia Universidade Católica do Rio de Janeiro (PUC-Rio)Universidade de Brasília (UnB)Universidade de São Paulo (USP), 2014)
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 ...
Falls Risk, Circadian Rhythms and Melatonin: Current Perspectives
(Dove Press, 2020-11)
Aging is associated with weakening of the circadian system. The circadian amplitude of most physiological variables is reduced, while the circadian phase becomes more labile and tends to occur earlier with advancing age. ...
