I was the interchangeable factor in the friendship; the money was not.
However, his research also showed that race and SES are related but not interchangeable social factors and combine in complex ways to affect health status and risk factors for health.
However, the extent to which podocyte proteins or their fragments are lost in the urine and the identities of any specific interchangeable regulatory factors are not yet known.
The existence of such large number of MBs may reflect the presumed multi-causal and equifinal etiology of post-traumatic morbidity, which posits many interchangeable contributing factors and many causal pathways.
Capillary and venous plasma glucose concentrations differ and are not interchangeable, and conversion factors do not accurately estimate equivalent values (46).
Promoters differ at their consensus sequence depending on the interchangeable polymerase σ factor used, which provides DNA recognition specificity [7], [8].
Overproduction of either DbpA or DbpB resulted in restoration of the infectivity of the mutant to the control level, measured by 50% infectious dose (ID50), indicating that the two virulence factors are interchangeable in this regard.
The adenoviral major late promoter fused to the G-minus sequence was transcribed in yeast extracts with an efficiency comparable to that observed in HeLa extracts, showing that promoters as well as transcription factors are functionally interchangeable across species.
These similarities can be used to explain why the two virulence factors can be interchangeable in the protection of B. burgdorferi against initial elimination by immune defenses when produced at an increased level; however, they indeed contribute differently to dissemination and tissue colonization.
These data are in complete accord with earlier findings (20, 21) and demonstrate that plasma and wild-type factor Va are interchangeable.
The down-regulated translation initiation factor EIF4A2 is interchangeable with EIF4A1 for the initiation of translation in general, and induces neural folding during embryonic development [ 110].
