How can you use “light-dark” in a sentence? Here are some example sentences to help you improve your vocabulary:
Experiments were performed on twelve male 200-300 gm Wistar rats, housed in controlled environmental conditions (22 ± 1°C, 12 h alternate light-dark cycles, food and water
The angle of the vector corresponds to the mean phase for the group of points, and the magnitude of the vector represents the variability in the phase estimates [ 32 ] . The Watson-Williams-Stevens statistic was applied to evaluate whether two such vectors are significantly different from one another [ 32 ] . Significant differences were evident in the phase of these two clock genes' cyclical expression under a light-dark cycle, for all tissues except isolated antennal pairs and the heads (see Figure 7) and 8.
To study the effects of adrenalectomy, insulin deficiency and fasting (Study 2) 33 male C57Bl/6J mice were obtained at 2 months of age from The Jackson Laboratory (Bar Harbor, ME) and were individually housed with free access to feed and water under 12:12 h light-dark cycle as described above.
These environmental conditions are the least likely to reveal deficits in the pattern of clock gene expression because the light-dark cycle provides a dominant stimulus to the clock (clock time is normally synchronized to this environmental cue) and is thought to increase the amplitude of clock gene cycling [ 20 28 29 ] . Rhythmicity was assessed for each specimen by autocorrelation analysis [ 30 27 ] . This analysis provides a quantitative estimate of rhythmicity with statistical confidence; whereas the confidence interval is based solely on the number of data points used in the analysis without relying on the variability in the data set or any other feature of the measured values, the criterion for statistical confidence is the same for all individual or group analyses within an experiment (see [ 27 ] for more detail).
This outcome is a logical consequence of the bimodal locomotor activity profile under a light-dark cycle.
