With increasing age we observed a steady rise in the number of γH2AX-foci, with significantly elevated foci levels in the age-group of <50 years (0.184±0.015 foci/cell; p<0.001) and even higher foci levels in the age-group of >50 years (0.245±0.023 foci/cell; p = 0.046).
In all cell fractions, we observed significantly increased numbers of γH2AX-foci for these elderly donors, with up to twice as high foci levels compared to the cord blood derived subpopulations (Fig. 4, upper panel).
But also more committed progenitor cells (CD34+CD38− and CD34−) and even peripheral blood mononuclear cells (PBMCs) revealed elevated foci levels compared to the cord blood derived subtypes (Fig. 4, upper panel).
Moreover, γH2AX-foci analysis of CD34− cells revealed a similar increase of unrepaired DSBs with increasing donor age, with significantly elevated foci levels in the <50 (0.145±0.018 foci/cell; p≤0.001) and >50 age-groups (0.247±0.036 foci/cell; p = 0.004).
In contrast, KU55933 increased foci levels in Lig4−/− MEFs in G2.
Moreover, depletion of Ku80 or Lig4 does not substantially affect BrdU foci levels.

We also overexpressed Artemis in control cells and observed that D37N-mutant Artemis, but not WT Artemis, increased the γH2AX foci level and decreased the Rad51 foci level.
Furthermore, expression of WT Artemis, but not D37N Artemis, restored the Rad51 foci level of Artemis-deficient fibroblasts.
About 60% have one focus and ∼34% have ≥2 foci (94% of cells with foci total), about 14-fold higher than spontaneous focus levels.
Users can take note of the type of activity that they're taking part in, as a way to track their focus levels over time.
Exercise is usually considered a remedy that helps both energy and focus levels.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
