Up to now, this chemical characterization has been based on analysis of different groups of components individually, due to difficulties related to their huge chemical variability.
Previous research on this issue, according to the Johns Hopkins team, has been based on analysis of racial differences in dialysis outcomes for all patients with end-stage kidney disease, a majority of whom are over the age of 50.
The phenotypic changes associated with B. anthracis have to this point been based on analysis of lysogens generated in laboratory infections.
Most population studies carried out in Africa have been based on analysis of the control region of mtDNA, sometimes complemented with analysis of hg diagnostic coding region sites [7], [8], [9], [10], [11], [12], [13].
Many of the inferences on properties of dendritic spines and calcium dynamics have been based on analysis of experimentally measured decay kinetics of calcium signals induced by a single back-propagating action potential.
The fusion searches that have been based on analysis of genomic rearrangements [ 9, 13], rather than on sequencing of cDNA, have also been incomplete, as judged by comparing the junctions reported with Array Comparative Genomic Hybridization data.
