The paper identifies hyperconnected metabolic networks in preclinical Alzheimer's converters using FDG-PET data, showing network reorganization precedes clinical conversion.

The paper investigates variability in FDG-PET imaging due to scanner manufacturer, reference region, age, and sex, and generates covariate-adjusted normative data.

This paper develops a multiple sampling scheme to construct stable brain metabolic networks from PET data, showing improved stability and reduced subject requirements compared to conventional methods.

This study compares hippocampal transcriptomics across AD mouse models and human patients, finding greater similarity between mouse models and late-onset AD.

This study shows that short-term consumption of ultra-processed semi-synthetic diets impairs olfactory function and brain metabolism in mice.

The paper investigates GFAP-positive astrocyte responses to amyloid-beta and tau pathologies in humans and mouse models, finding distinct molecular signatures associated with each pathology.
