Furthermore, only larvae and nymphs habitually feed on rodents, so that natural amplification of TBE virus to allow persistent cycles depends on transmission from the relatively few infected nymphs to the much more abundant infectible larvae (which then moult to infected, host-seeking nymphs up to one year later) [10].
The respiratory disease is characterized by persistent cycles of lung infection and inflammation leading to mucous obstruction of the airways.
The rationale behind this analysis is that because of the various stages in Chlamydiae infections (infectious and persistent cycles) we hypothesize that the different GroEL protein copies are performing distinct functions, as their expression levels are different.
The free-play nonlinearity introduces persistent limit cycle oscillations (LCO) which can cause water noise, and it will have an undesirable effect on the concealment capability of marine vehicles.
In all examined gastropods, and in two other molluscan classes, part or all of the 1d12 clone enters a persistent cell cycle arrest while corresponding cells of the 1abc12 lineages proliferate to form definitive head structures [6], [7], [22], [27], [45], [47], [49], [53].
Persistent cell cycle stress and genotoxicity in Nde1 mutants after p53 abrogation.
Unlike the hMEC lines, prolonged arrest of U2-OS cells correlated with persistent cell cycle progression and subsequent apoptosis (Supplementary Figures S6a and b).
Whether ecologic conditions during the period of Ae. albopictus activity in southern Europe and North America support the development of a productive and persistent viral cycle in local vector populations is unknown.
The increase lasted throughout the four-day treatment, indicating induction of a persistent cell-cycle arrest in the G2/M stage of the cell cycle by G-1 in PC-3 cells.
