The ubiquity of 'self-care' in health: Why specificity matters.

Despite increased interest in self-care for health, little consensus exists around its definition and scope. The World Health Organization has published several definitions of self-care, including in a 2019 Global Guideline rooted in sexual and reproductive health and rights (SRHR), later expanded to encompass health more generally. To establish a robust understanding of self-care, this exploratory study inventorises, consolidates, presents and analyses definitions of self-care beyond the SRHR field.

Senataxin and RNase H2 act redundantly to suppress genome instability during class switch recombination.

Class switch recombination generates distinct antibody isotypes critical to a robust adaptive immune system, and defects are associated with autoimmune disorders and lymphomagenesis. Transcription is required during class switch recombination to recruit the cytidine deaminase AID-an essential step for the formation of DNA double-strand breaks-and strongly induces the formation of R loops within the immunoglobulin heavy-chain locus. However, the impact of R loops on double-strand break formation and repair during class switch recombination remains unclear.
