These assays do not measure rates of import, but just the resultant of import and export localization at steady-state.
Consequently, the rate constants κ of import and export are set individually, and were to be estimated in the optimization procedure.
The results of these experiments revealed that compared to the rapid exchange of EGFP across the nuclear envelope, the rates of nuclear import and export of EGFP-LC3 are relatively slow.
To compare the rates of nuclear import and export of RPL27-GFP, we selected daughter HeLaRPL27-GFP cells post mitosis (ensuring that both cells were at the same cell-cycle stage) and performed photobleaching to selectively remove either the nuclear or cytoplasmic GFP fluorescence.
The introduction of many invasive species can be tracked with the routes of certain imported goods, such as wooden packing materials and live nursery stock, etc. [30], [34] Enhancement of supervision on economy and commerce related invasive pathways is the most effective way to reduce invasion frequency and diffusion rates, especially regarding important ports of import and export.
Thus, in the following, mechanisms of active transport and passive diffusion are lumped, resulting in the apparent transport rate for import, (12) and in the apparent transport rate for export (13) described by the product of apparent rate constant κ im/ex of import or export and extra- or intracellular concentration, respectively.
Development of steatosis is largely due to increased rate of import or synthesis of fatty acids by hepatocytes that exceeds the rate of export or catabolism [ 42- 44].
It has traditionally been a country that both sent and received migrants, but its rate of export of human capital is now far higher rate than its rate of import.
Nuclear localization depends on relative rates of nuclear import and nuclear export.
"As such, the underlying growth rates of both imports and exports ought to moderate in coming months".
