Among all the modifications of the signal peptide, only the addition of a 10-residue spacer peptide (EEAEAEAEPK) between the α-factor prepro-signal and the phytase gene increased yield, by 12%% relative to that of the α-factor signal peptide alone, to 626 U/mL (Fig. 3a).
In order to confirm the midbrain DA identity of the Dkk1-expressing cells at E10.5, we analyzed the expression of Dkk1 relative to that of Lmx1a, a transcription factor expressed in the entire DA lineage [38].
Boguslaw Pawlowski, an anthropologist at the University of Wrocław in Poland, says that it's still unclear what role imprinting plays relative to other factors that influence mate choice.
Retrospective approaches require building an integrated assessment that provides a measure of the importance of the chemical discharges relative to other factors that can cause adverse biological responses.
First, the impact of noise must be weighed relative to other factors that may be more or less disruptive to patients' sleep.
This suggests that constraint on the coding sequence, as captured by d N/d S, has not played as large a role in preventing neo-Y gene degeneration relative to other factors that we discussed.
Evaluating the impact of noise on sleep quality is challenging, as it must be measured relative to other factors that may be more or less disruptive to patients' sleep.
In [ 16], the authors argue that over short time scales inherited factors become small relative to stochastic factors, and that over very long time scales the variation causes the auto-correlation from lineage to lineage to break down.
Here, regional factors are stronger relative to local factors, such that migration can rescue populations in suboptimal habitat.
Using the distribution fitting algorithm a positive and statistically significant t-value indicates that the factor is statistically more important relative to the other factors and that there is more agreement with the factor or statement, a negative and significant t-value indicates the factor is less important and that there is less agreement with the factor [ 9].
"These are estimates, and the study doesn't tell us the importance of soft drinks relative to the other factors that contribute to obesity," said the study's lead investigator, Dr. David Ludwig, director of the obesity program at Boston Children's Hospital.
