Abbreviations: ABC, ATP binding cassette; ABCB1, ATP-binding cassette, subfamily B; EPG85-257P, parental gastric cancer cells; EPG85-257RDB, gastric cancer cells selected against daunorubicin; EPG85- 257RNOV, gastric cancer cells selected against mitoxantrone; EPP-181 RDB, pancreatic cancer cells selected against daunorubicin; EPP-181P, parental pancreatic cancer cells; EPP-181RNOV, pancreatic cancer cells selected against mitoxantrone; FAR, fluorescence

Mean activity counts for before and after pheromone exposure (left), and the mean after/before
activity ratio (right), for un-irradiated (0 Gy = -) and irradiated (300 Gy = +) Epiphyas postvittana males.
However, the rise in ADAMTS13 antigen levels was not accompanied by a proportional increase in ADAMTS13 activity, since ADAMTS13 activity/ADAMTS13 Ag ratio was lower and VWF/ADAMTS13
activity ratio was higher in DM1 patients with nephropathy.
Concordance among PONI phenotypes determined by serum PONI
activity ratios ([kappa] = 0.997).
Consequently, soils that have undergone recent weathering display [sup.234]U/[sup.238]U
activity ratios <1.
Measured [sup.210]Pb: [sup.226]Ra
activity ratios for each age group, along with their total sample age (predicted age + time since capture), were plotted with the expected [sup.210]Pb: [sup.226]Ra growth curve.
Therefore, for x < 34 for men (and x < 42 for women), the
activity ratio ([a.sub.x+j] / [a.sub.x]) exceeds one for some j.
For our reserve components, we would prefer not less than a one-to-four
activity ratio, and ideally one-to-five, based on reserve component Airmen continuing to volunteer to deploy as they have been doing in substantial numbers for many years.
Notably, the results for the elevated plus maze were observed in 2 independent experiments, demonstrating that this effect is robust, even though the decrease in
activity ratio was more obvious in both experiments compared with the latency ratio.
The acquired SME in comparison with nonacquired SME have higher
activity ratio (ASSET_TURN).
The simultaneous measurement of sPLA2 activity in both CSF and serum from the same cases, at equal protein concentrations, revealed a CSF: serum sPLA2
activity ratio of 1:2.5.
As a consequence, the principle of using a phytoestrogen such as daidzein (or ethinylestradiol) as a reference compound for estrogenic activity and extrapolating from the
activity ratio calculated from acute data to long-term risk of chemicals with a different structure cannot be considered to represent a valid approach.
