BACKGROUND AND PURPOSE This study was aimed at the comparative analysis of serum concentrations of glial fibrillary acidic protein (GFAP) and protein S-100B in patients with acute stroke. METHODS We investigated 32 patients with stroke symptoms consistent with cerebral ischemia in the anterior territory of vascular supply. Serial venous blood samples were(More)
Alzheimer's disease (AD) probably involves several pathobiochemical mechanisms and this may be reflected by changes in different serum components. The present study investigated whether the combined analysis of serum molecules related to different mechanisms improves the discrimination of AD patients from healthy controls. Serum of patients with AD was(More)
The diagnosis of Alzheimer's disease (AD) is currently based on clinical and neuropsychological examination. To date there is no blood test available that can discriminate dementia patients from healthy individuals. In the present paper, an overview of the current state of knowledge on biologic markers in serum (plasma) and CSF is presented. The combination(More)
The present study investigated if a causal relation exists between serum concentrations of precursors and metabolites of cholesterol and cognitive performance in a healthy aging population. Cognitive function addressing four domains of 144 individuals (30-80 years) was tested at baseline and after 6 years of follow-up. Serum concentrations of different(More)
The relation between serum inflammatory protein levels and cognitive performance was investigated in a healthy population. Individuals were tested during 6 years of follow-up. Serum concentrations of 10 inflammatory proteins were correlated to cognitive speed (Letter-Digit Coding Test, LDCT), attention and information processing (Stroop) and memory (Word(More)
The 3-nitropropionic acid animal model is a model where excitotoxicity, mitochondrial dysfunction and oxidative stress, mechanisms common to various neurodegenerative diseases, are involved. The present study investigated whether behavioural alterations in this model were related to striatal damage. Wistar and Lewis rats were exposed to 3-nitropropionic(More)
The present study investigated whether 3-nitrotyrosine is an early marker for neurodegenerative processes involving oxidative stress. We characterized the 3-nitrotyrosine formation after 3-nitropropionic acid (3-NP) exposure in the whole brain spheroid culture model and in a rat model, using Lewis and Wistar rats. Increased 3-nitrotyrosine concentration in(More)
In the present study, we examined the long-term effect of oxidative stress induced neurodegeneration on sterol concentrations in striatum and serum of Wistar and Lewis rats. Three weeks after treatment with 3-nitropropionic acid, no differences in 24S-hydroxycholesterol concentrations were observed in striatal homogenates and serum. Ratios of striatal(More)
UNLABELLED Age-related macular degeneration (AMD) is the leading cause of blindness in the Western world. AMD is a multifactorial disorder but complement-mediated inflammation at the level of the retina plays a pivotal role. Oral zinc supplementation can reduce the progression of AMD but the precise mechanism of this protective effect is as yet unclear. We(More)
Little is known of the biochemical processes of cognitive decline during 'healthy' aging. Biological markers in body fluids, such as blood, could provide insight in those processes. In the present studies serum concentrations of different markers have been correlated to cognitive functioning of cognitively healthy aging individuals over a period of six(More)
