Compared to the corresponding unprotected recognition schemes, genuine match rates of approximately 95 and 97 % at which no false accepts are observed and maintained in a single- and multi-instance scenario, respectively.
Further studies are clearly warranted to delineate the specific genes and gene networks that are affected by sGC and whether these changes are observed and maintained into the next generation.
In this case, we decided the operation because marked tumor regression was observed and maintained for several months after chemotherapy, although the finding around SMA was not completely diminished.

Soulé (1971) argued that relatively low levels of genetic variability should be observed and maintained in cave-dwelling organisms [ 50]; reviewed in [ 16].
Overall, the long-term study results support those from the phase 2 and phase 3 controlled clinical trials [ 30- 33] in demonstrating a similar safety profile; similar improvements across multiple clinically meaningful FM domains were observed and maintained throughout the duration of the study.
A maximum value of −25 mGal at station 9 is observed and maintains a value of about −40 mGal towards the southern end of the traverse, while small highs and lows are caused by local features (Fig. 4(a)).
This method allows for frequent inspection of seed production fields along with rigorous rouging when off-type plants are observed; and has helped to maintain early generation lines for more than two decades enabling farmers to access true-to-type hybrid seed every season.
Earlier work had been of a simple character balconies, for instance, being in the form of a succession of balusters but as the smith became more versatile and imaginative, they took the form of panels of flowing curved scrolls, rendered with a freedom never attained before, while constructive strength was observed and symmetry maintained.
