Sentence examples for breathing fluctuations from inspiring English sources

While modulation of BOLD signal has been correlated with end-tidal CO2 and other measures of breathing, fluctuations in performance of BH have not been studied in the context of their impact on BOLD signal.

Discussion of base pair melting a kin to "breathing" fluctuations at the DNA junction would be useful to explain that the two enzymes together shift the equilibrium of the junction base pairs even more to the open/melted state than either enzyme alone, thereby producing a synergistic/larger fluorescence.

Despite these shortcomings, the use of a moving heart phantom offered the advantage of ensuring highly reproducible conditions at each of the three imaging modalities, whereas studies in human subjects intrinsically suffer from lack of consistency due to different variables, such as physiological non-constant heart rates caused by breathing or fluctuations in fluid status.

It also limits breathing induced fluctuation of proximal airway pressure and time where proximal pressure exceeds safety alarm limits during breathing.

The immediate marked reduction in Vbs with rib cage breathing indicates that fluctuations in Pab are responsible for the blood shifts.

The maximum force the airway smooth muscle can generate is exquisitely sensitive to muscle length fluctuations during breathing, and is governed by complex mechanotransduction events that can best be studied by a hybrid approach in which the airway wall is modeled in silico so as to set a dynamic muscle load comparable to that experienced in vivo.

In the light of this result we hypothesize that the protein concentration in the large Zera-Xyl oligomers impairs the conformational fluctuations, namely "breathing" [45], which would be needed to accommodate the substrate in the optimum environment.

at different LBNP levels and at 6/min and 15/min patterned breathing, which demonstrates the enhanced fluctuations at moderate hypovolemia and slow patterned breathing in heart rate, arterial blood pressure and central venous pressure.

Whether the larger gain relation between respiration and cardiovascular fluctuations during yogic breathing represents baroreflex modulation or is due to enhanced entrainment through repetitive practice remains to be established.

It is well known that in the awake, spontaneously breathing human the respiratory hemodynamic fluctuations increase at lower breathing frequencies (despite constant tidal volume) and have a maximum of approximately 0.1 Hz (that is, the frequency of the spontaneously occurring Mayer waves) [ 19- 21].

Furthermore, when breathing took place with only minimal fluctuations in Pab we found, as predicted, that the blood shifts were very small and the WBP and OEP tracings were essentially identical.
