These results are consistent with an increased SNS activity mechanism, but does not preclude Sry effects on other important blood pressure regulation systems like the tissue renin angiotensin system.
Since it is rather unlikely that there are sudden or abrupt changes in the heart-rate or blood-pressure regulation system, especially when the subjects are studied whilst supine, we can assume that RRI and SAP spectra vary only slowly.
Since the coherence and especially phase between the SAP and RRI at this frequency varied over time, it is unlikely that this oscillation is a part of the blood-pressure regulation system, so it can be regarded as a secondary effect of some other mechanisms.
Although it has slightly lower specific impulse performance than nitrogen, it has a significantly higher storage density and it stores at a very low pressure, hence no regulation system is required.
Losses can be minimized by selecting the proper length of the laterals and pipeline diameter and by applying appropriate pressure regulation throughout the system.
During sleep, the renin-angiotensin system plays a more important role in blood pressure regulation than the sympathetic nervous system unless the sympathetic system is activated (23).
This study can provide technological support for achieving pressure regulation in the hydrogen transport system of FCEV when facing complex conditions, and it can also benefit the further research work on energy saving and multi-stage flow of pressure reducing devices.
Under acidic conditions, the depth-averaged NO concentration in dental plaque increased from 0.08 to 0.15 μM, which is in a physiological effective range [ 42, 43] for local blood pressure regulation, neurosignalling events and immune system modulation in tissues close to plaque.
The finding of enrichment for genes in the RAS is not unexpected, given the central role of this system in blood pressure regulation.
Finally, there is interplay between GH, NO-system and blood pressure regulation.
