BMP signaling promotes zebrafish heart regeneration via alleviation of replication stress.

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.

Compulsive sexual behavior, sexual functioning problems, and their linkages to substance use among German medical students: exploring the role of sex and trauma exposure.

Sexual problems relevant to psychotherapy, such as compulsive sexual behavior (CSB) and sexual functioning problems (SFP), have been related to harmful substance use in several studies. Substance use is prevalent among medical students (MS) and is often considered a maladaptive coping strategy for stress, as well as a risk factor for mental health issues. Sexual problems and substance use share trauma exposure and post-traumatic symptoms as risk factors for their development.

[Innovation in abortion care during the COVID-19 pandemic in Germany, France and Great Britain : Paths to maintaining access and building system resilience].

The COVID-19 pandemic has had a drastic impact on healthcare systems. They had to react, adapt and innovate in order to build resilience, that is maintain healthcare access and health equity. For example, access to abortion services during the pandemic was increasingly facilitated through "Telehealth for Early Medical Abortion" (TEMA).

Quantitative determination of the spatial distribution of components in single cells with CellDetail.

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.

Experiences and life circumstances of unintentionally pregnant women affected by intimate partner violence-stress factors, resources, healthcare structures and needs: a scoping review protocol.

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.
