In an attempt to elucidate the pathological implications of intracellular accumulation of the amyloid precursor protein (APP) in postmitotic neurons in vivo, we transferred APP695 cDNA into rat hippocampal neurons by using a replication-defective adenovirus vector. We first improved the efficiency of adenovirus-mediated gene transfer into neurons in vivo by(More)
This morphometric, quantitative and correlative multivariate study of the hippocampal formation in human brains from two distinct normal aging populations provides an additional support to the notion that neuritic plaques (NP) are an earlier stage of the pathological process underlying neurofibrillary tangle (NFT) formation. It is shown that the rate of(More)
In this paper, we present a new platform for experimenting with net-worked systems and distributed applications called Virtualized Application Networking Infrastructure (VANI). This infrastructure is designed as a converged communications and computing infrastructure that would facilitate operation of an open applications marketplace. VANI enables(More)
While modulating neural activity through stimulation is an effective treatment for neurological diseases such as Parkinson's disease and essential tremor, an opportunity for improving neuromodulation therapy remains in automatically adjusting therapy to continuously optimize patient outcomes. Practical issues associated with achieving this include the(More)
The molecular basis for sporadic Alzheimer disease (AD) remains largely unknown. We hypothesized that in some cases of sporadic AD, a somatic mutation in an embryonic cell committed to neuronal development within the amyloid precursor protein (APP), the presenilin 1 (PS-1) or the presenilin 2 (PS-2) genes (genes known to be involved in familial AD) may(More)
Neuronal size and the incidence of neuritic plaques (NPs) and neurofibrillary tangles (NFTs) were morphometrically and quantitatively studied in the entorhinal cortex of 300 autopsied individuals without dementia in three geographically distinct series (Brazil, Germany and Japan), and an additional series including 30 clinically diagnosed Alzheimer's(More)
