However, more prolonged delays of ≥18 and ≥24 weeks had substantially reduced sensitivity for LTFU despite higher specificity.
Delays of the ≥6 and ≥12 weeks were 100% sensitivity for true LTFU whereas more prolonged delays showed much lower sensitivities.
Given that increased levels of DA activity are needed to support spatial working memory performance with more prolonged delays [ 30, 31], it might be expected that defeated rats with lower mPFC DA activity would have shown spatial working memory deficits during the 30, 60, and 480 min delay on the delayed win-shift task compared to controls.
More prolonged pharmacy delay cut-offs identified substantially fewer patients as potential LTFU.
To investigate whether this same sleep-dependent emotion memory effect would occur following a more prolonged postlearning delay, a second experiment was performed in an addition group of subjects (n = 17; 8 males, mean age 22.9 [SD ± 1.4]; screened as described above).
Indeed, cancer cells respond to DNA damage by initiating the DNA-damage response (DDR), which induces cell cycle delay, more prolonged growth arrests (senescence) and apoptosis of the lethally damaged cells.
Similarly, they showed a more prolonged fever and a delayed recovery from LPS-induced suppression of social interaction.
The new result "makes a great deal more biological sense than the prolonged delay" of recoveries, says paleontologist Douglas Erwin of the National Museum of Natural History in Washington, D.C.
Of interest in this regard, only continual KLK6 exposure, but not short pulses up to 60 min in duration, were able to delay cell death over more prolonged culture periods.
In contrast, the wild-caught starlings showed a delayed, but much greater and more prolonged response to the human stressor that had failed to return to baseline levels by the end of the observation period.
