For example, a variety of analytical methods exist for dealing with selection bias 60 64 and surveillance bias.
Novel analytical methods exist to model a past history of drug use flexibly up to the time point when risk is being assessed.
Various analytical methods exist that first quantify gene expression and then analyze differentially expressed genes from Affymetrix GeneChip® gene expression analysis array data.
These data demonstrate that very sensitive analytical methods exist to measure trace levels of benzene in blood, expired air or urine and that the analytical results are comparable among suitably equipped and highly skilled laboratories in various countries.
Bodily lipids, proteins, glycoproteins, and nucleic acids are subject to oxidative injury, and a number of analytical methods exist for measurement of oxidative by-products in blood and brain tissue samples.
