Our data strongly support the notion that tRNA gene transcription in eukaryotes is modulated by composite TFIIIB binding sites that may confer responsiveness to variation in TFIIIB activity and/or concentration.
Secondly, ACPAs likely represent products of long-lived memory plasma cells [ 30], whereas RF may be at least partly produced by a particular subset of B lymphocytes, B-1 cells; the former may have less plasticity and responsiveness to variations of the disease process or might be less involved in cell-cell interactions in RA than the latter [ 31, 32].
The large temporal variation in green roof effluent water quality supports the need for long-term studies to characterize the complexity of these engineered ecosystems and their responsiveness to environmental variation.
From a policy perspective, it appears that investments in livestock marketing systems might enhance drought adaptation by increasing pastoralist marketing responsiveness to climatic variation.
The difference between lifespan at MAX and MIN serves as a surrogate for sensitivity (or responsiveness) to long-term variation in UVR.
We also propose a new means of testing for Hawthorne effects based on excess responsiveness to experimenter- induced variations relative to naturally occurring variation.
As conceptualized in contemporary neurobiological models (Craig, 2002, 2009) and illustrated by the present behavioural data, these are complex psychological constructs: alteration in a patient's responsiveness to pain or temperature variations might reflect altered awareness, tolerance, motivation, behavioural organization or some interaction of these, all potentially dissociable processes.
Other mechanisms that could account for differential responsiveness to IFNß include variation in activity of inhibitory transcription factors.
The MAX minus MIN (in years) was our measure of sensitivity (for example, responsiveness) to long-term variations in UVR.
Sensitivity analysis evaluates the responsiveness of results to variation or errors in parameter values and assumptions.
There have been no reports to date indicating whether there is variation in the ability to form RW among genotypes and, if so, whether variation in responsiveness to such conditions can contribute to genotype-specific variation in cell wall recalcitrance.
