In contrast to mammals, adult zebrafish achieve complete heart regeneration via proliferation of cardiomyocytes. Surprisingly, we found that regenerating cardiomyocytes experience DNA replication stress, which represents one reason for declining tissue regeneration during aging in mammals. Pharmacological inhibition of ATM and ATR kinases revealed that DNA damage response signaling is essential for zebrafish heart regeneration.

The distribution of biomolecules within cells changes upon aging and diseases. To quantitatively determine the spatial distribution of components inside cells, we built the user-friendly open-source 3D-cell-image analysis platform Cell Detection and Analysis of Intensity Lounge (CellDetail). The algorithm within CellDetail is based on the concept of the dipole moment.

Unlabelled: This scoping review outlines the current understanding, challenges, available resources, and healthcare needs of women affected by intimate partner violence (IPV) who experience unintended pregnancy (UP). UPs are defined as unwanted, unplanned, or mistimed pregnancies. The impact of UP is multifaceted and carries several additional risks, particularly for women who experience IPV.
