Needless to say, this turnover has whipsawed AOL's sales force, not to mention the marketers and advertising agencies that it is trying to build relationships with.
Hughes, towering until now, was stripped of the ball in a tackle only for Rhys Priestland, on at half-time for Eastmond, to kick this turnover treasure away.
Any programme of this nature needs strategies to overcome this turnover.
In addition to this rapid-turnover ERC pool, we propose that multivesicular bodies represent the slow-turnover pool for HDL endocytosis (Fig. 1) [44].
Since the PSII proteins were present in variable amounts in Δflv mutants at LC growth conditions (Figure 4), it was next studied whether this is related to the turnover of the D1 protein in mutant strains.
Although intestinal stem cells (ISCs) are thought to be responsible for this turnover, their identity and cell cycle status remain to be established (Clevers, 2013).
It remains to be seen whether this turnover is stimulated by homeostatic (e.g., relative IL-15 abundance) or other, perhaps antigen-driven, mechanisms.
We speculated therefore that the βPS gradient might be due to endocytic turnover of Integrins on the basal surface of midgut cells, and that the loss of a gradient and increased levels of αPS1/βPS at the plasma membrane in netAB Δ and fra mutants might be due to a disruption of this turnover.
However, recent revisions to the lithostratigraphy of the traditional Petrified Forest Member within PEFO [11] [12] have made this turnover appear to be more gradual than previously thought, with a period of overlap between the faunas [7], [26] [28].
As opposed to this mesofrontal dopaminergic turnover (MDT), dopamine turnover in nigrostriatal pathways is much less affected.
