As mentioned earlier, previous reports regarding the NPS system have mainly documented the findings obtained with regard to the central nervous system as well as components other than NPS levels, such as NPSR
levels and genetic receptor variations, while our results included only the plasma NPS levels, which is a peripheral measure with regard to the NPS/NPSR system.
On the other hand, NPS has been shown to activate hypothalamic-pituitary-adrenal axis and increases the release of ACTH (3-5) and mutations that make NPSR
more active, for both single nucleotide polymorphisms and mutations at the promoter sequence, causes subjects to be more susceptible to have panic disorder (3-5-10-17).
Moreover, even in those instances where either the Yeltsin government or the opposition claimed victory, given that neither side provided anything but limited resources to candidates, and the NPSR
in particular played such a small role in nominating candidates, "party association offered candidates a limited boost at best." As their subsequent actions have demonstrated, "none of the winners were likely to feel strong bonds of loyalty to either camp." (53)
