We recently described the first recombinant Schistosoma mansoni protein RP26, which was capable of acute infection diagnosis. The aim of the present work was to further characterize the RP26 diagnostic properties in immunoblot and enzyme-linked immunosorbent (ELISA) assays. Testing sera from uninfected donors and sera from patients with acute or chronic(More)
We obtained a recombinant protein encoded by Schistosoma mansoni gene which was able to differentiate acute from chronic schistosomiasis when applied as antigen in enzyme-linked immunosorbent assay (ELISA). A cDNA clone encoding a 26 kDa recombinant protein (RP26) was selected by screening of an adult worm S. mansoni lambdaZAP expression library with rabbit(More)
 We wished to test whether thrombopoietin (TPO) is entirely regulated by receptor binding or if other factors may play a role in the mechanism of TPO regulation. Therefore, we analyzed the TPO serum levels in 43 patients with reactive (secondary) thrombocytosis and in 37 with myeloproliferative thrombocytosis. Thrombocytosis was defined as a platelet level(More)
We studied the effects of fullerene C60 nanoparticles, namely hydrated fullerene C60 (C60HyFn), on interrelations between EEG frequency spectra from the frontal cortex and the dorsal hippocampus (CA1) on an amyloid-β (Aβ) rat model of Alzheimer's disease (AD). Infusion of Aβ1-42 protein (1.5 μl) into the CA1 region two weeks before EEG testing diminished(More)
Amyloid β-peptides (Aβ) play a key role in the development of Alzheimer’s disease (AD). The response of neurons to the administration of Aβ in experimental animal models of AD remains poorly studied. We investigated the early effect of Aβ25–35 in neurons of the CA1 field of the hippocampus after intraventricular or intrahippocampal injections. We used(More)
The dynamics of the state of hippocampal pyramidal neurons after intrahippocampal microinjections of (1) amyloid-beta25-35 (1.6 nmol/1 microl), (2) an aqueous molecule-colloidal solution of C60 (0.46 nmol/1 microl) and (3) an aqueous molecule-colloidal solution of C60 before amyloid-beta25-35 administration were analysed in rats. This model allowed us to(More)
Primary memory impairments associated with increased level of amyloid-β (Aβ) in the brain have been shown to be linked, partially, with early pathological changes in the entorhinal cortex (EC) which spread on the whole limbic system. While the hippocampus is known to play a key role in learning and memory mechanisms, it is as yet unclear how its structures(More)
BACKGROUND AND PURPOSE The important pathological consequences of ischaemic heart disease arise from the detrimental effects of the accumulation of long-chain acylcarnitines in the case of acute ischaemia-reperfusion. The aim of this study is to test whether decreasing the L-carnitine content represents an effective strategy to decrease accumulation of(More)
It has been shown for the first time by transmission electron microscopy that the hydrated fullerene C60 inhibited the fibrillization of amyloid-beta25-35 peptide. The fullerene affected the amyloid-beta25-35 assembly, manifesting its anti-amyloidogenic capacity. Our in vivo investigations demonstrated also that a single intracerebroventricular injection of(More)
