The rapid growth of multi-omics datasets and the wealth of biological knowledge necessitates the development of effective methods for their integration. Such methods are essential for building predictive models and identifying drug targets based on a limited number of samples. We propose a framework called GNNRAI for the supervised integration of multi-omics data with biological priors represented as knowledge graphs. Our framework leverages graph neural networks (GNNs) to model the correlation...

CONCLUSIONS: Although it may be difficult for residents with dementia to maintain their social networks as part of their illness, there are numerous ties that attest to the social roles of persons with dementia in the community. These ties can be used to provide person-centred care, but are also an important resource in finding and retaining personnel and volunteers.

Substantial progress in aging research continues to deepen our understanding of the fundamental mechanisms of aging, yet there is a lack of interventions conclusively shown to attenuate the processes of aging in humans. By contrast, replacement interventions such as joint replacements, pacemaker devices and transplant therapies have a long history of restoring function in injury or disease contexts. Here, we consider biological and synthetic replacement-based strategies as aging interventions....

CONCLUSION: A "1.0" universal person-centered home time measure that reflects QoL should include days in the emergency department, inpatient care, and post-acute care. Expert input revealed domains of agreement and disagreement. Future validation efforts that incorporate expert input are needed to iterate and arrive at the optimal measure.

Polycomb repressive complexes (PRCs) are pivotal epigenetic regulators that preserve cell identity by restricting transcription responses to sub-threshold extracellular signals. Their roles in osteoblast function and bone formation remain unclear. Here in aging osteoblasts, we found marked activation of PRC1.1 complex, with KDM2B acting as a chromatin-binding factor and BCOR and PCGF1 enabling histone H2A monoubiquitylation (H2AK119ub1). Osteoblast-specific Kdm2b inactivation significantly...

Although electrochemical technologies offer vast industrial prospects, broader adoption-particularly in consumer applications-remains constrained by high costs and limited component lifespans. Here, we present a gravity-assisted, membrane-free electrochemical oxygen (O(2)) removal (EOR) reactor coupling oxygen reduction (ORR) and oxygen evolution (OER) reactions. Leveraging fluid mechanics insights, buoyant O(2) bubbles ascend rapidly, achieving 95% product self-separation and eliminating the...

Calcific aortic valve disease (CAVD) is a cardiovascular disease prevalent in the aging population, resulting in high morbidity and mortality rates. However, the molecular mechanisms underlying CAVD remain unclear. We initially conducted an RNA sequencing analysis of aortic valve leaflets from rats of different ages to identify key genes involved in valvular aging and calcification. Bioinformatics analysis demonstrated that methionine sulfoxide reductase A (MSRA) was crucial to valvular...
