To determine whether these markers are useful to predict neurologic complications, it will be necessary to exclude contamination from the surgical field as observed in the present study.
To exclude contamination by infrasonic waves, we used the 1-s seismogram observed before the infrasonic onset (red line in Fig. 12a).
The study overcomes limitations in prior studies in that it (1) assessed personal characteristics before study entry in order to exclude "contamination" effects, (2) selected an appropriate control group, and (3) differentiated between STEM and non-STEM study majors.
The use of cyclododecane solution as an insulator is an effective method but the method of pressing the layered sample in KBr pellets which exclude contamination of the sample by any other compound remains superior.
However, this analysis did exclude contamination with any common cell lines that have been previously profiled.
In order to exclude contamination and check for likely functionality, we analyzed genomic features and EST (expressed sequence tag) data.
All positive samples were repeated for confirmation in different runs of PCR amplification to exclude contamination occurrence.
To exclude contamination with mouse DNA, we also designed and used a mouse-specific DNA PCR test.
To exclude contamination with lipoproteins, polymeric staphylococcal PGN (PGNpol) was isolated from Staphylococcus aureus Δlgt (lacking lipidated prelipoproteins).
The presence of an intron, subunit fusion and expressed sequence tags covering parts of the gene exclude contamination and suggest a functional gene.
To exclude contamination of IEC by other cells, isolated cells were stained with FITC-coupled anti-G8.8 antibodies, specific for epithelial cells [44].
