Alternatives: "a fairly stable level" or "a relatively steady level".
TRPC1 mRNA showed a rather constant level in all tested brain areas while other isoforms varied considerably.
Although this could suggest that development of this biofilm occurred with a rather constant level of heterogeneity, single-channel analyses indicated otherwise.
One can speculate that the data presented in Figure 8 represent the plateau of this distortion where the Sr/Cs activity ratio of most foodstuffs remains at a rather constant level between 1 and 10.
The number of publications using the Salmonella assay rose dramatically, peaking at approximately 500 papers/year in the early 1980s, but has declined gradually to a rather constant level of approximately 200 papers/year during the past decade.
An interesting result was that the bees regulated the Tth at a rather constant level in a broad range of Ta (10 27 °C) on average but showed a strong variation at a certain Ta, depending on the plants from which they were foraging (Fig. 3).
On average, the thorax surface temperature (Tth) was regulated at a high and rather constant level over a broad range of ambient temperatures (Tth = 33.7 35.7°C, Ta = 10 27°C).
Interestingly, well-known cancer-associated TFs like c-Fos, c-Jun, Smad3, and c-Ets-2 exhibited rather constant levels of upregulation throughout tumorigenesis.
The LAGs are relatively evenly spaced, indicating cyclical growth at a rather constant rate.
In all likelihood this concept may partly explain the increased efficacy of pegylated interferon [ 16, 17] since the rather constant interferon levels with this type of interferon result in a constant block of virus production.
These results suggest that, while the number of enteroendocrine cells expressing burs is rather constant, the levels of burs within these cells are regulated.
