We identified five lines of reported intercross origin (AtT-20, B6x129-1, CAKB3, IM3 and OB1xB3) that appear to have been backcrossed prior to derivation of the cell line.
Furthermore, STR assays may lack the resolution to discriminate between cell lines derived from closely related inbred strains [ 5], or to identify partial contamination, such as outbreeding that occurred prior to derivation of the cell line.
However, based on our previous observations in the rhesus monkey and published reports in mouse and human PESCs (Kim et al., 2007a; Kim et al., 2007b; Revazova et al., 2007; Dighe et al., 2008), the majority of loci in parthenotes are heterozygous, having undergone meiotic recombination prior to derivation.
When statistically deriving a prediction model, the contribution of clinical expertise prior to model derivation is often minimal.
A methodology of preliminary appraisal, by contrast, articulates criteria for the evaluation of a hypothesis prior to rigorous derivation or testing.
So, it is suggested in this paper to modify the original GLUE methodology by applying a new procedure designed to at least partially correct the simulation/prediction of the hydrological model prior to the derivation of the prediction limits at each time step, in an attempt to improve the efficiency of the GLUE prediction limits in enveloping the real-world observations.
Extraction, liquid partition, and derivation prior to GC-MS analysis were performed as described by Lisec et al. [ 35].
To minimize noise propagation, the muscle curve was fitted with an empirical mathematical model [ 33] prior to this derivation.
For descriptive statistics and the exposure-response analysis, the changes from baseline in QTcN of the placebo periods were averaged prior to the derivation of the placebo corrected MCfB.
Additionally, these lines exhibited a non-random genomic distribution of discordant markers, which is indicative of introgression prior to the derivation of the cell line rather than contamination [ 22] (Additional file 10).
