Uranium (U) is the heaviest naturally occurring element ubiquitously present in the Earth's crust. Human exposure to low levels of U is, therefore, unavoidable. Recently, several studies have clearly pointed out that the brain is a sensitive target for U, but the mechanisms leading to the observed neurological alterations are not fully known....
The development of nuclear industries has raised multiple questions about its impact on the biotope and humans. Proteins are key biomolecules in cell machinery and essential actors in deciphering toxicological processes. Phosvitin was chosen as a relevant model for phosphorylated proteins and because of its important role as an iron, calcium,...
Uranium is widespread in the environment, resulting both from natural occurrences and anthropogenic activities. Its toxicity is mainly chemical rather than radiological. In the blood it is transported as uranyl UO22+ cation and forms complexes with small ligands like carbonates and with some proteins. From there it reaches the skeleton, its...

Uranium is a natural element widely found in the environment, due to both natural occurrence in mineral ores or in sea water and industrial applications. The production of nuclear energy uses enriched uranium in $^{235}$U for nuclear fission. Despite its ubiquitous distribution, uranium has no essential role in living organisms and presents...
