| Measure | Time frame |
|---|---|
| The main parameter of the study is the amount of deuterium (label) that the different leukocyte populations have incorporated in their DNA by cell division at a given time. For this purpose blood withdrawals are done both in the period during which participants drink 2H2O (uplabelling phase), and in the period after stopping with 2H2O intake (delabelling phase). Data obtained during uplabelling and delabelling phases can be interpreted by mathematical models that describe the dynamics of leukocyte populations. | — |
