Serotonin and circadian rhythms
(Pontifícia Universidade Católica do Rio de Janeiro (PUC-Rio)Universidade de Brasília (UnB)Universidade de São Paulo (USP), 2010-12-01)
All mammal behaviors and functions exhibit synchronization with environmental rhythms. This is accomplished through an internal mechanism that generates and modulates biological rhythms. The circadian timing system, ...
Time for circadian rhythms: plants get synchronized
(Current Biology Ltd, 2009-10)
Most organisms adjust their physiology and metabolism in synchronization with the diurnal and seasonal time by using an endogenous mechanism known as circadian clock. In plants, light and temperature signals interact with ...
Circadian rhythm of wrist temperature and night shift-work
(Taylor & Francis LtdAbingdonInglaterra, 2013)
Circadian and seasonal variation of the body temperature of sheep in a tropical environment.
Nychthemeral and annual rhythms of the rectal temperature were determined for Corriedale sheep in a tropical climate. The minimum rectal temperature averaged 39.55 degrees C at 0500 hours in summer, and 38.87 degrees C at ...
Circadian rhythms in the vegetative state
(Taylor & Francis Ltd, 2009-10)
Objective: To evaluate whether vegetative state patients maintain circadian rhythms. Research design: An observational study of five single cases. Methods and procedures: Five chronic vegetative state patients underwent ...
Timing of locomotor activity circadian rhythms in Caenorhabditis elegans
(Public Library of Science, 2009-10)
Circadian rhythms are driven by endogenous biological clocks and are synchronized to environmental cues. The chronobiological study of Caenorhabditis elegans, an extensively used animal model for developmental and genetic ...
Vasoactive Intestinal Polypeptide Mediates Circadian Rhythms in Mammalian Olfactory Bulb and Olfaction
(Society for Neuroscience, 2014-04)
Accumulating evidence suggests that the olfactory bulbs (OBs) function as an independent circadian system regulating daily rhythms in olfactory performance. However, the cells and signals in the olfactory system that ...
