Promoting wellbeing for youth is a global health priority and young people with chronic conditions demonstrate disproportionately low wellbeing compared to their peers. However, wellbeing is variably defined, and little is understood as to what wellbeing means for this population. The aim of this study was to develop a conceptualisation of wellbeing that is rooted in the perspectives of young people with chronic conditions.
Base editing technologies enable programmable single-nucleotide changes in target DNA without double-stranded DNA breaks. Adenine base editors (ABEs) allow precise conversion of adenine to guanine. However, limited availability of optimized deaminases as well as their variable efficiencies across different target sequences can limit the ability of ABEs to achieve effective adenine editing.
The presence of membrane-bound organelles with specific functions is one of the main hallmarks of eukaryotic cells. Organelle membranes are composed of specific lipids that govern their function and interorganelle communication. Discoveries in cell biology using imaging and omic technologies have revealed the mechanisms that drive membrane remodeling, organelle contact sites, and metabolite exchange.

The structures and functions of organelles in cells depend on each other but have not been systematically explored. We established stable knockout cell lines of peroxisomal, Golgi and endoplasmic reticulum genes identified in a whole-genome CRISPR knockout screen for inducers of mitochondrial biogenesis stress, showing that defects in peroxisome, Golgi and endoplasmic reticulum metabolism disrupt mitochondrial structure and function.
More than 1 in 5 children experience neglect, exposing them to several adverse consequences. Children with intellectual disability experience additional neglect related challenges. Public perceptions significantly influence the identification, intervention, and prevention of child neglect.
Breakdown of mitochondrial proteostasis activates quality control pathways including the mitochondrial unfolded protein response (UPRmt) and PINK1/Parkin mitophagy. However, beyond the up-regulation of chaperones and proteases, we have a limited understanding of how the UPRmt remodels and restores damaged mitochondrial proteomes.
The ability to balance conflicting functional demands is critical for ensuring organismal survival. The transcription and repair of the mitochondrial genome requires separate enzymatic activities that can sterically compete, suggesting a life-long trade-off between these two processes.
RNA-binding proteins and mitochondrial ribosomes have been found to be linchpins of mitochondrial gene expression in health and disease. The expanding repertoire of proteins that bind and regulate the mitochondrial transcriptome has necessitated the development of new tools and methods to examine their molecular functions.
There is no known risk-free level of alcohol use in pregnancy. Despite this, many still believe that occasional drinking is safe. To-date, there is limited evidence of the influences on women's decisions about low to moderate alcohol use in pregnancy.
