Mindfulness cultivates awareness, presence, and non-judgmental acceptance, enhancing overall well-being. Inflammaging, linking age and aged-related diseases, manifests through heightened levels of IL-6, TNF-α, and CRP, impacting aging indicators like TA, TL, PWV, and FMD. To assess how mindfulness-based interventions (MBIs) affect inflammaging, a search was conducted in PubMed, Web of Science, Cochrane Central Register, and ProQuest Dissertation & Theses Global up to March 2024.

INTRODUCTION: The cerebellum is essential for motor control and learning, relying on structural and functional integrity. Age-related atrophy leads to Purkinje cell loss, but subtle neurochemical changes in GABA, Glx (glutamate + glutamine), and glutathione (GSH) may precede degeneration and contribute to motor decline.

The intensive production and use of plastics, poor biodegradability and inadequate recycling have caused excessive and alarming environmental pollution. This has led to the inevitable intake by humans, through different routes, of small plastic particles, the micro and nano-plastics (MNPs) with sizes ranging from nanometers (<1000 nm) to micrometers (from 5 mm to 1 µm). MNPs can cause harmful effects in human tissues and organs, contributing to the early onset of aging and various age-related...

Alzheimer's Disease (AD) drug discovery has been hampered by patient heterogeneity, and the lack of sensitive tools for precise stratification. Here, we demonstrate that our robust and interpretable AI-guided tool (predictive prognostic model, PPM) enhances precision in patient stratification, improving outcomes and decreasing sample size for a AD clinical trial. The AMARANTH trial of lanabecestat, a BACE1 inhibitor, was deemed futile, as treatment did not change cognitive outcomes, despite...

Secretory proteins aggregate into non-soluble dense-core granules in recycling endosome-like compartments prior to regulated release. By contrast, aberrantly processed, secreted amyloid-β (Aβ) peptides derived from amyloid precursor protein (APP) form pathological extracellular amyloidogenic aggregations in late-stage Alzheimer's disease (AD). By examining living Drosophila prostate-like secondary cells, we show that both APP and Aβ peptides affect normal biogenesis of dense-core granules. These...

CONCLUSIONS: Using cross-population GWAS meta-analyses, we identify novel LOAD susceptibility loci in/near LRRC4C and LHX5-AS1, both with known roles in neuronal development, as well as several novel population-unique loci. Reflecting the power of diverse ancestry in GWAS, we detect the SHARPIN locus with only 13.7% of the sample size of the NHW GWAS study (n = 409,589) in which this locus was first observed. Continued expansion into larger multi-ancestry studies will provide even more power for...
