Model: Male ApoE−/− mice fed a high-fat diet for 12 weeks to induce atherosclerosis.
Dosage: Methyl-β-cyclodextrin (Mß-CD) at 2.0 g/kg, subcutaneous injection, twice a week

 A new study shows cyclodextrin reduces artery plaques in mice by lowering cholesterol and blocking inflammatory cell death.

Model: C57BL/6J mice, J20 mice, and 3xTg mice 
Dosage: 4.3 μEq l−1 of lithium in drinking water starting at 10 to 12 months of age and continued for 10 to 14 months during aging

Harvard Study: A Low Dose of Lithium May Preserve Cognitive Resilience with Age

Researchers uncover significantly lower brain lithium levels in Alzheimer’s disease patients, and supplementing with a low-dose lithium salt restores memory in an Alzheimer’s disease mouse model.
