For this purpose, western blot analysis using a phosphospecific Ab directed against Src-Tyr416, which constitutes a marker of Src activation, was performed.
Medication count may constitute a marker for severity of illness or an expression of conventional medicines not working, however this proposition could not be tested.
Atypical low morning cortisol in early pregnancy may be an indicator of HPA dysfunction, however, additional research that includes adverse pregnancy outcomes is needed to determine if these atypical cortisol levels may constitute a marker for risk later in pregnancy.
Ward suggested that as Medicare can be obtained by patients receiving Social Security Disability Insurance, Medicare might constitute a marker for more severe illness than observed with other types of healthcare insurance.
Furthermore, gene AK023526 has been found to constitute a marker for cancer stem cells [ 32], and gene NOTCH2 has been associated with tobacco use disorders and certain types of cancer [ 28].
We speculate that the early ERP expression effect (around the P1) might constitute a marker for a signal that acts to direct processing resources toward potential threat in the environment, in accord with previous imaging data on P1 responses to emotional stimuli [e.g., Pourtois et al., 2004, 2005b].
Flagellar sequence variation constitutes a marker with widespread potential uses for studies of population genetics and phylogeny of bacterial species.
Thus, one could investigate which of the two markers constitutes a better marker for the illness and may, therefore, be more suitable for differentiating the most severe patients (e.g., those with substance misuse, more suicide attempts and a more severe course of illness).
Interestingly, this hypomethylating effect has also been achieved in a number of clinical trials employing these agents in hematological malignancies; in fact, measurement of this biological effect constitutes a surrogate marker for the activity of these agents [47].
