The contrast agent is repeatedly destroyed in order to estimate the time required for local replenishment.
Parameters are estimated based on this strategy and include measures of the spatial extent of flow, the spatial integral of flow, and the time required for 80% replenishment.
The article is devoted to cost estimations of summary characteristic velocity (SCV) required for formation and replenishment of constellations functioning at circular and near-circular orbits in non-central gravity fields.
In the adult pancreas, Ngn3 expression is very limited, but levels rise during β cell neogenesis induced by pancreatic duct ligation, where Ngn3 is required for β cell replenishment (Van de Casteele et al., 2013; Xu et al., 2008).
By employing genetic deletion of Lrp6 in nestin+ MSCs, we have established that this transmembrane protein is crucial for bone marrow MSCs to preserve their growth and proliferation potential, and therefore, is required for the sufficient replenishment of osteoblasts and the maintenance of bone mass.
Continuous replenishment of leaf litter may be required for long-term seedling culture.
These findings imply that an early COX-2/PGE2 signaling is required for the induction of stem cell-driven cardiomyocyte replenishment.
These signals may not only function in replenishment of ER stores, but also stimulate local Ca2+ pathways required for cone signaling and survival [68].
However, blood gas electrodes were not readily adaptable for this type of monitoring because they required frequent replenishment of reagents and recalibration.
The running distance before required lubricant replenishment was thus determined to be within a range of 90 100 km.
