Recent findings suggest that neurotoxicity is the mechanism underlying the induction of neuronal insulin resistance by a high cholesterol diet. Troxerutin, a naturally occurring flavonoid, has been reported to possess biological activity beneficial to human health. Our recent studies have demonstrated that troxerutin attenuates cognitive impairment and(More)
Purple sweet potato color (PSPC) has been shown to possess hepatoprotective effects in our previous study. To clarify the detailed mechanism of hepatoprotective effects of PSPC, we investigated the potential protective effect of PSPC against caspase-3 activation induced by d-gal, as well as its influence on Bcl-2 levels and PI3K/Akt cell survival pathway.(More)
It is known that a high-cholesterol diet induces oxidative stress, inflammatory response, and beta-amyloid (Abeta) accumulation in mouse brain, resulting in neurodegenerative changes. Quercetin, a naturally occurring flavonoid, has been reported to possess numerous biological activities beneficial to health. Our previous studies have demonstrated that(More)
Evidence indicates that systemic administration of lipopolysaccharide (LPS) induces brain inflammation, ultimately resulting in cognitive deficits. Ursolic acid (UA), a plant-derived pentacyclic triterpenoid, is well known to possess multiple biological functions, including antioxidant, anti-tumor and anti-inflammatory activities. In the present study, we(More)
