Some members of Barbie's clade, like Barbie herself, are long-lived and reach high frequencies and wide distributions, while others persisted effectively just for an instant.
Thus, we concluded that artificial box C/D RNAs effectively accumulated and persisted in human cells at least 72 h under the transfection conditions used.
Worse, the essential cause of Mali's problems — the racial divide, which effectively split the country — persisted, and, with it, the unresolved question of Mali's identity.
Except 2 patients whose CAR transgene copy numbers declined to the baseline value within 1 month, 9/11 patients' serum CAR transgene copy numbers were still above 2-fold of the baseline level at the first evaluation timepoint, showing that CART-HER2 cells could persist effectively in vivo.
Both are highly selfing, short-lived perennials that reproduce effectively from seed, persist in disturbed areas, and survive moderate fires, with gene flow occurring primarily through wind-dispersed seeds (Young and Evans 1977; Britton et al. 1990; Jones 1998; Larson et al. 2003).
The original ATP6[1] genome is still displaced, but the newly emerged recombinant competes effectively and persists.
What if her cancer had persisted in a dormant state during her remissions — effectively frozen but ready to germinate?
When treated effectively, patients tend to persist longer with antipsychotic treatment, have fewer costly relapses, and have improved functioning.
However in pseudo-addiction, analgesic-seeking behaviour stops when the pain is treated effectively and does not persist after pain relief has been achieved [ 27].
All of these are reasons for expecting asexual species of unicellular yeasts to persist more effectively than might be expected for multicellular animals, in which asexual species are extremely rare.
