Dementia with Lewy bodies (DLB) is characterized by the widespread presence of Lewy bodies (LBs) in the brain. alpha-Synuclein, the main component of LBs, is expressed as two main isoforms (112 and 140), but little is known about their differential expression in the brain. We compared alpha-synuclein 112 and alpha-synuclein 140 expression levels in the(More)
Alternative splicing gives rise to at least seven parkin and eight synphilin-1 isoforms. Since both parkin and synphilin-1 have been involved in Lewy body (LB) formation, we decided to explore whether their isoforms are differentially expressed in LB diseases. With this aim, we studied relative mRNA expression levels of parkin and synphilin-1 isoforms in(More)
Cystatin C is an amyloidogenic protein that colocalizes with beta-amyloid (Abeta) within arteriolar walls in Alzheimer disease (AD) brains. Recently, a coding polymorphism in the cystatin C gene (CST3) has been claimed to confer risk for the development of late-onset AD. In the present work we have tested the frequencies of CST3-A and CST3-G alleles and(More)
Amyloid precursor protein (APP) is involved in the accumulation of alpha-synuclein, the main component of Lewy bodies. It is currently unknown, however, whether any of the APP isoforms is instrumental in alpha-synuclein deposition in dementia with Lewy bodies (DLB). Using real-time RT-PCR, we have studied relative mRNA expression levels of APP isoforms in(More)
Alzheimer disease (AD) patients show increased plasma levels of homocysteine, whose conversion to methionine is catalyzed by methionine synthase (MS). Although altered MS activity may result from the MS A2756G polymorphism, the latter's possible associ-ation with AD remains unexplored. To assess whether the MS A2756G polymorphism holds any influence on AD(More)
In situ hybridization (ISH) for JC virus (JCV) is generally applied for the diagnosis of progressive multifocal leukoencephalopathy (PML). To explore the usefulness of immunohistochemistry (IHC) for JCV early proteins, 14 paraffin-embedded postmortem brain specimens with histologic features compatible with PML were tested for the presence of JCV by means of(More)
JC virus (JCV), the agent of progressive multifocal leukoencephalopathy (PML), has been shown by both immunohistochemistry and flow cytometry to be associated with p53 protein stabilization. Since stabilization/inactivation of p53 is associated with the development of genomic instability, abnormal cell DNA contents are to be expected in JCV-infected cells(More)
All work contributed to this book is new, previously-unpublished material. The views expressed in this book are those of the authors, but not necessarily of the publisher. Abstract This chapter presents two different techniques for elicitation and analysis of requirements for a mobile electronic patient record (EPR) to be used in hospital wards. Both(More)
