From calcified tissue stores, Pb is slowly released, depending on bone turnover rates, which in turn are a function of the type of bone, whether compact (slow turnover) or trabecular (rapid turnover) (O'Flaherty 1995).
In the second half, Tennessee cut the lead slowly, through turnovers and defense, finally taking the lead with 9 25 remaining.
In contrast, slow decaying (∼50 Gg) and highly recalcitrant (∼250 Gg) soil Hg pools are large reservoirs that turnover slowly.
Conversely stem cells that turnover slowly and thus divide infrequently generate long lived differentiated cells; a trait arguably favourable within adult tissues [ 8, 77].
To satisfy the requirement for stability, urothelium cycles extremely slowly, with a turnover rate of about 200 days and a tritium-thymidine labeling index of less than 0.01% [ 27, 28].
The preceding discussion indicates that the most toxicologically relevant targets of ACR are those nerve terminal proteins that turnover slowly and are importantly involved in neurotransmitter release, storage, and re-uptake.
The Raptors, who finished with 24 turnovers, slowly gave back a 10-point first-half lead.
Whereas the juvenile pancreas grows rapidly, in parallel with the organism, the adult pancreas grows slowly and exhibits little turnover.
Interestingly, in serum-starved cells, the average number of punctae increased marginally over time, suggesting that the rate of autophagosomal induction and turnover increases slowly and stably.
21 Our observations are similar to those in Kenyan altitude natives training at sea-level, where a decrease in Hbmass was not observed until a number of weeks at sea-level, 22 indicating that in altitude natives living at 3600 m or lower, any decrease in Hbmass is a result of slowly altered red cell turnover as opposed to rapid neocytolysis.
