In fact, it has been found that PEGylated CNTs can persistently exist within liver and spleen macrophages for 4 months with excellent compatibility [53].
Why do they persistently exist?
In addition, the concentration of p53 oscillates, which results from reactivation from ATM when DNA damage persistently exists.
EA1 has been well known as a major S-layer component of B. anthracis vegetative cells, and it also persistently exists in the spore preparations and bind tightly to the spore surfaces even after rigorous washing.
Whichever is correct, it does not matter for the detection of B. anthracis spores, because this protein does persistently exist in each of the spore preparations (Fig. 8), and the B. anthracis spores, even after full washing, can be detected with our anti-EA1 mAbs (Fig. 2 and Fig. 7).
Elastic-net regularization would perform better than LASSO in GWA analysis, in which multicollinearity persistently exists due to linkage disequilibrium among nearby SNPs [ 24].
Although the end-point titer of anti-DKK1 was only 1 : 1600, the specific antibody existed persistently in the serum up to 6 months after immunization.
But, when ac > bd, the population exists persistently and is harmful after reaching high density.
When subcutaneously and abdomenally administered, a part of CNTs exist persistently in the local tissues while some of them may be absorbed through lymphatic canal.
Then, Theorem 1 tells us that if R0 ≤ 1 then the population dies out; otherwise, (1) possesses a globally asymptotically stable positive equilibrium and hence the population exists persistently.
