BACKGROUND AND PURPOSE Early-onset Alzheimer's disease (EOAD) and late-onset Alzheimer's disease (LOAD) have different clinical and neuroimaging characteristics, but memory decline is usually present in both types. However, there have been few functional studies focused on the hippocampus in Alzheimer's disease. We therefore investigated the functional connectivity between the hippocampus and o...
Using plasma amyloid beta protein (Abeta42) levels as an intermediate, quantitative phenotype for late onset Alzheimer's disease (LOAD), we previously obtained significant linkage at approximately 80 cM on chromosome 10. Linkage to the same region was obtained independently in a study of affected LOAD sib-pairs. Together, these two studies provide strong evidence for a novel LOAD locus on chrom...
BACKGROUND Since cytomegalovirus (CMV) infection can cause serious clinical complications in immunocompromised individuals, we assessed cellular immune requirements for protection against CMV end-organ disease (CMV-EOD) in human immunodeficiency virus type 1 (HIV-1) infection. METHODS Longitudinal samples from HIV-1-infected patients in the Amsterdam cohort were analyzed. Dynamics of CMV-spec...
We investigated patterns of white matter (WM) loss in 18 early onset (EO) and 24 late onset (LO) Alzheimer's disease (AD) patients compared with 42 healthy controls (HC), and explored relationships of WM atrophy and apolipoprotein E (ApoE) genotype. Subjects underwent magnetic resonance imaging (MRI). Patterns of WM were assessed using voxel-based morphometry. Compared with healthy controls, LO...
INTRODUCTION One major factor that influences the heterogeneity of Alzheimer's disease (AD) is age: younger AD patients more frequently exhibit atypical forms of AD. We propose that this age-related heterogeneity can be understood better by considering age-related differences in atrophy in the context of large-scale brain networks subserving cognitive functions that contribute to memory. METH...
The relationship between detection threshold of inspiratory resistive loads and the peaks of the respiratory-related evoked potential (RREP) is unknown. It was hypothesized that the short-latency and long-latency peaks of the RREP would only be elicited by inspiratory loads that exceeded the detection threshold. The detection threshold for inspiratory resistive loads was measured in healthy sub...
This study aims at better understanding the damage tolerance of stiffened composite panels subjected to fatigue loads in post-buckling regime. Ten single-stringer hat-stiffened specimens with an initial delamination between skin and stringer foot were manufactured, then tested under quasi-static conditions, different load levels ratios. The tests monitored digital image correlation ultrasonic s...
Several studies have reported evidence for linkage of late-onset Alzheimer's disease (LOAD) to chromosome 9. Recently, an intronic polymorphism affecting alternative splicing of exon 8 of ubiquilin 1 (UBQLN1) was reported to be associated with LOAD. We attempted to replicate this observation by genotyping this polymorphism, rs12344615 (also known as UBQ-8i), in a large sample of 1,544 LOAD case...
objective: serum leptin concentration reflects the body fat mass. there is controversial reports about the insulin effect on serum leptin concentration. we wanted to examine the effect of insulin therapy on serum leptin in children with new onset type i diabetes. materials and methods: this was a cross-sectional study in children's medical center on 34 children who had new onset type i dia...
BACKGROUND/AIMS Some studies have implicated the role of apolipoprotein J [clusterin (CLU), apoJ] in the pathogenesis of Alzheimer's disease (AD). In this study, we investigated the polymorphisms rs11136000 and rs9331888 within CLU in late-onset sporadic AD (LOAD) patients and nondemented subjects. METHODS LOAD patients and control subjects were analyzed. Genotyping of rs11136000 and rs933188...
