Research into the underlying mechanisms of cognitive dysfunction in Alzheimer's disease (AD) has relied traditionally on tasks such as the water maze which evaluate spatial learning and memory. Since non-spatial forms of memory are also disrupted by AD, it is critical to establish other paradigms capable of investigating these deficits. Utilizing a(More)
Diet restriction (DR) in rodents increases lifespan, reduces age-related disease and pathology, increases stress responses, and maintains better function later into life compared with conventional ad libitum (AL) feeding. We have been investigating different DR regimens and also DR mimetics that stimulate stress response pathways that are activated by DR.(More)
The objective of this study was to examine whether and how TNF-α affects glutamine-enhanced protein synthesis and the expression of the amino acid transporter ASCT2 in the small intestine at the mRNA and protein levels. A total of 30 male Sprague-Dawley rats were randomly assigned into three groups, namely the total parenteral nutrition (TPN; control),(More)
