Further experiments in mice confirmed this SCN-restricted pattern of Fbxl21 expression, and demonstrated pronounced diurnal and circadian expression rhythms, rising rapidly at the start of the day (or "subjective day" in animals run into constant darkness), and declining at the onset of the (subjective) night (Fig 5B).
Both dive depth and frequency were approximately constant outside of the periods of twilight or darkness (2100-0600), but declined rapidly to zero during the night, driving the strong relationship between those variables and time of day (Fig. 6) Dive frequency was slightly higher when wind was from the north.
What's out there is darkness, uncertainty, decline, and recession.
In mouse rods [Ca2+]i is ∼250 nM in darkness and declines to ∼20 50 nM during bright illumination [1], [2].
When plants were kept in constant darkness, sucrose content of stolon-ends declined linearly over time indicating that changes in sucrose supply from the leaves contributes to the oscillating expression of GBSS in tubers.
Winifred was puzzled by the fact that, as German prospects declined, Hitler preferred the terminal darkness of Götterdämmerung to the cheery cultural nationalism of Meistersinger.
Conscience is accompanied in each case by an internal awareness of 'inner light' and approbation or 'inner darkness' and condemnation as well as a resulting conviction of right or duty either followed or declined.
I declined, and a few minutes later I heard the Nautilus machine gently whirring in the darkness.
Total glucosinolate levels declined by 70%and88%8%, respectively, in cabbage disks stored at 22°C under constant light or constant darkness (Additional file 1: Figure S6B).
We found that germination rates declined significantly with increasing salinity, with the greatest germination occurring in treatments subjected to 24-h darkness at either 15 or 20 °C.
