A method to quantify and value floodplain sediment and nutrient retention ecosystem services.

Floodplains provide critical ecosystem services to local and downstream communities by retaining floodwaters, sediments, and nutrients. The dynamic nature of floodplains is such that these areas can both accumulate sediment and nutrients through deposition, and export material downstream through erosion. Therefore, estimating floodplain sediment and nutrient retention should consider the net flux of both depositional and erosive processes.

Long-Term Follow-Up of De Novo Use of mTOR and Calcineurin Inhibitors After Kidney Transplantation.

Background: Long-term efficacy and safety of de novo use of the mammalian target of rapamycin inhibitors (mTORi) have been evaluated primarily using registry data.

Methods: This was a pooled retrospective analysis of data obtained from 10 prospective randomized trials in de novo kidney transplant recipients (n = 581) receiving calcineurin inhibitors (CNIs) combined with sirolimus (n = 329), everolimus (n = 128), or antimetabolites (n = 124).

Results: There were no differences in patient (84.
