Most researches are performed for the prevailing vessel-type light water reactors, such as PWRs and BWRs.
In proliferating areas with very high cell density and Ki-67/MIB.1 labelling LI, hyperchromatic nuclei, and scanty cytoplasm, it was common to find Nestin+ cells around capillaries or larger vessels, prevailing on GFAP+ cells– 1(c)).
The pack ice was (and remains) thick; and at the time of his decision, there were two large icebergs moving in parallel to the trapped vessel on the prevailing east to west current.
If functionality of body organs becomes of prevailing importance, it could be argued that the body is predominantly a vessel equipped with all the necessary instrumentation for maintaining life and that is occupied and used by the person to whom the body belongs.
As regards humans, on the other hand, information has until recently been scarce concerning how experimental manipulation of prevailing arterial pressure influence the in vivo pressure-distension relationships in precapillary vessels.
That changes in the prevailing transmural pressure may also affect the in vivo mechanical properties of precapillary resistance vessels, is supported by experimental findings on animals, that long-term intravascular pressure elevations increase local blood-flow resistance (for reviews see Folkow 1982, 1990; Intengan and Schiffrin 2000; Zhang 2001).
For some time, the prevailing explanation for this effect has been the concept of 'vascular normalisation.' Tumour vessels are known to be leaky and dysfunctional, leading to increased interstitial fluid pressure, which may in turn impede the delivery of chemotherapy [ 71, 72].
However, surprisingly, we found that eNOS knockouts exhibited normal collateral vessel growth after femoral artery occlusion and showed delayed recovery only because of the prevailing intense vasoconstriction, which was easily neutralized by NO-donors [ 35, 71, 94, 125].
The prevailing concept holds that the tumor vasculature is formed via a mechanism of tumor angiogenesis: pre-existing blood vessels, which are stimulated by various angiogenic growth factors secreted by cancer cells, such as vascular endothelial growth factor (VEGF), angiopoietin (Ang -1, Ang -1g-2, sprout into cander cell clusters to form tumor vasculature [1], [2].
It is perhaps less obvious whether, or in what manner, changes in the prevailing transmural pressure will, in turn, affect the tone and/or structure, and hence the elastic recoil, of these vessels.
Perhaps the prevailing climate mattered.
