Sentence examples for perhaps low levels of from inspiring English sources

Perhaps low levels of expression of neuronal genes are characteristic of neuro-epithelia in general.

Perhaps, low levels of antigen at the peak of the response trigger a nominal level of activation allowing for proliferation without the induction of full effector functions, which in turn favor the development of precursors of long-lived memory T-cells.

We hypothesized that very high specific activity and lower injected mass of [ 18 F]flutemetamol might provide an advantage in some animal models that did not show increased specific binding with [11C]PIB in our previous study, perhaps because of low levels of high-affinity binding sites [4].

It is tempting to speculate (and has been speculated), therefore, that this maternal environmental event is related to a low maternal sun-exposure (perhaps resulting in low levels of vitamin D) while the child is in utero [21], [24].

Identifying glucokinase protein reliably has been more challenging, perhaps because of low levels of expression.

However, Activin A treated 'stimulator' wild type ESCs were not able to induce GFP expression in 'responder' Mixl1GFP/w cells (Figure 4B, C), perhaps reflecting the relatively low levels of growth factor gene expression observed in d3 EBs that had been stimulated with Activin A for only 24 hours (Figure 3C, D).

Although BC influenced ST-segment depression, we did not find independent effects of CO on ST-segment level, perhaps because of the low levels of exposure.

Another possibility is that we sampled patients in the early phase of disease (within 24 hours after admission), which perhaps could explain the low levels of a 'late-onset' proinflammatory cytokine such as HMGB1.

In contrast to T47D cells that signal to ERK5 in response to either HGF or MSP (in the face of low mRNA expression for both receptors), both HaCaT and MDA-MB-231 cells failed to respond to MSP over a 90-min time course, while HGF remained a potent input to ERK5 activation, perhaps reflective of their low levels of Ron relative to Met receptor mRNA.

We suggest that in non-diapausing tissue, the epithelium is primed to initiate proliferation, and does so to a small extent during the second 24 hr period a.p., perhaps in response to very low levels of ecdysteroid present at that time.

This is particularly the result of co-morbidity, which is especially common among older persons and perhaps above all those with low levels of social support [ 38].
