To identify genes aberrantly expressed in the brain of individuals with Alzheimer's Disease (AD), we analyzed RNA extracts from the hippocampus and cerebellum from 19 AD patients and 15 age- and sex-matched control subjects. Our analysis identified a number of genes that were over-expressed or...
The discrepancy between cohort and case-control studies regarding the association between smoking and Alzheimer's disease (AD) has been attributed to the competing risk of early mortality of smokers. A simulation study was conducted to show that the bias favoring smokers acts also on cohort...
Supplementing a rabbit's diet with 2% cholesterol alone or with a trace amount of copper created neuropathological changes that resembled those seen in Alzheimer's disease (AD). AD model rabbits were impaired in eyeblink classical conditioning; a form of learning severely impaired in AD. Our aim...
Neuronal cell loss is a critical feature of age-related neurodegenerative diseases such as Alzheimer's disease (AD). In the AD brain, a marked increase in pro-inflammatory cytokines and chemokines, including IL-8, has been documented. The objective of this study was to determine the effect of...
Multiple aspects of homocysteine metabolism were studied to understand the mechanism responsible for hyperhomocysteinemia toxicity in Alzheimer disease. Besides oxidative stress and vascular damage, homocysteine has also a great importance in regulating DNA methylation through...
Alzheimer's disease (AD) is a devastating neurodegenerative disorder characterized by progressive memory deficits and cognitive decline. We explored the possibility that Environmental Enrichment (EE) may reduce the disease progression in a comprehensive mouse model for AD like neurodegeneration,...
Aldehydic products from ozonation of cholesterol and peroxidation of phospholipids have been shown to accelerate aggregation of amyloid-β (Aβ) in vitro. Here, we show that 3β-hydroxy-5-oxo-5,6-secocholestan-6-al (ChSeco), an ozonation product of cholesterol, induces Aβ aggregation, generation...
