Evidence of a diurnal rhythm
was indicated by a significant cosinor model fit.
as a previous study showed environmental changes affect the diurnal rhythm
of sports performance ).
IC placed in the uterotubal junction was successfully to measure intrauterine temperature and detected diurnal rhythm
may persist when the organism is placed in an environment devoid of time cues, such as constant light or constant darkness.
These data are in agreement with recent observations of similar hepcidin diurnal patterns for individuals with and without food intake and corroborate previous findings that transcriptional regulators related to genes involved in diurnal rhythm
are potentially significant modulators of hepcidin expression (7, 15).
It is demonstrated that the plasma glucose level has a diurnal rhythm
in rats, which depends on the circadian secretion of melatonin or the control mechanism of suprachiasmatic nucleus on hepatic glucose delivery (6,13).
Estimates of period length close to 24 h were considered evidence of a diurnal rhythm
, provided that all model parameters were estimated with high statistical significance (P < 0.
A 24-1 glass tank (W:D:H = 40:20:30 cm) was used to monitor the diurnal rhythm
and behavior (swimming or not swimming) of the medusae.
Circulating proprotein convertase subtilisin kexin type 9 has a diurnal rhythm
synchronous with cholesterol synthesis and is reduced by fasting in humans.
The biggest increase of serum FGF21 concentrations started around midnight (0000), reached its peak at around 0500 of the second day, and then slowly declined to a nadir in the afternoon, suggesting that FGF21 secretion is regulated by the diurnal rhythm
14) reported that healthy nonobese individuals who fasted for 3 days developed a diurnal rhythm
in ghrelin characterized by low concentrations in the morning with subsequent increases in the afternoon and at midnight.
None of these crystals appeared to be deposited in a diurnal rhythm
