Feedback was provided in the form of a green "correct" or red "incorrect" in text in the space between the sample and matches at about the center of the projected screen.
This increase is primarily attributable to spectral interferogram k-space resampling error, which becomes more pronounced as the fringe frequency increases with depth, along with incomplete dispersion matching between sample and reference arms of the OCT interferometer.
In this analysis we have compared indices of pathway activity between treated samples and matched controls (Figure 1, Step 2) and between toxic and non-toxic chemicals (Figure 2, Step 2).
Moreover, there was no significant difference between tumor samples and matched normal tissues for BsaXI RFLP status.
Thus, although an increase in Dsc2 message levels was found in one sample, the majority (six of seven) showed no significant changes in Dsc2 transcription (i.e. there was <2-fold difference in expression levels between tumour samples and matched controls).
Estimates were also weighted to account for the distance between sampled stores and matched unsampled stores, with closer stores contributing more to the estimated prescription volume.
After testing four different housekeeping genes, HMBA was selected as the control housekeeping gene for tumour samples because its cycle threshold value showed the least variation between samples and its efficiency closely matched the transcription efficiency of the target genes.
SOCSs mRNA expression (with the exception of SOCS5) showed no significant difference between cancer tissue samples and matched normal background tissue.
To minimize analytical errors, amplitudes of ion beams were matched between samples and standards by regulating amounts of the analyses introduced into IRMS.
Arsenic sulfides were identified by retention-time matching between samples and fortified samples.
