The phrase "absence of autoregulation" is correct and usable in written English.
It can be used in contexts related to physiology, medicine, or any field discussing regulatory mechanisms in systems.
Example: "The study highlighted the absence of autoregulation in the blood flow to the affected area, leading to complications."
Alternatives: "lack of autoregulation" or "deficiency of autoregulation".
44 45 The values for the ARI index range from 0 to 9, with 9 indicating perfect autoregulation, and 0 meaning complete absence of autoregulation.
The solution assumed an absence of autoregulation (effect of studied factors is independent of autoregulation) and the rigidity of all vessels.
In the absence of autoregulation, the only factor that contributes to a decrease in the ratio of DnaA-ATP to non-specific binding sites is the increase in DNA after DNA replication has begun.
To examine the influence of autoregulation, we classified the FFCs according to the presence or absence of autoregulation on each regulator of an FFC without respect to the regulators' modes.
Therefore, the absence of intermediary autoregulation was a hallmark for avoidance of FFC formation.
In the absence of vascular autoregulation, a high cardiac output in combination with a reduced ODR (the situation after late resuscitation) could indeed be expected to lead to an increased mitoPO2 compared with baseline.
In contrast to the monomer-binding case, we found Models 2-4 all all capable of exhibiting bistability, even in the absence of direct positive autoregulation.
In particular, we found that dimerization of the active GL3-GL1 complex and cooperative sequential binding of GL3-GL1 thethe CPC promoter are each independently sufficient to generate a bistable subnetwork, even in the absence of direct positive autoregulation.
The results show that a working system can still be produced in the absence of RIDA or DnaA autoregulation.
Given the absence of all conditions that define autoregulation, these results should be regarded as preliminary data, and further studies, employing bigger samples, are warranted.
Using this experimental approach we were also able to finally show that nitrate reductase does not act as a co-repressor of NirA in the absence of nitrate, as suggested by the autoregulation model put forward by Cove and coworkers.
