Effects of amyloid beta (Aβ) peptide Aβ(40) on secondary structures of Aβ(42) are studied by all-atom simulations using the GROMOS96 43a1 force field with explicit water. It is shown that in the presence of Aβ(40) the beta-content of monomer Aβ(42) is reduced. Since the fibril-prone conformation N∗ of full-length Aβ peptides has the shape of beta strand-loop-beta strand this result suggests tha...
OBJECTIVES The purpose of this study was to carry out systematic review of the literature and meta-analysis to evaluate the diagnostic utility of cerebrospinal fluid (CSF) levels of the 42 amino acid form of amyloid-beta (Aβ1-42) as a biomarker for differentiating Alzheimer's disease (AD) from non-AD dementia. METHODS Design. Systematic literature review was used to evaluate the effectiveness...
Two strains of transgenic mice have been generated that secrete into their milk a malaria vaccine candidate, the 42-kDa C-terminal portion of Plasmodium falciparum merozoite surface protein 1 (MSP1(42)). One strain secretes an MSP1(42) with an amino acid sequence homologous to that of the FVO parasite line, the other an MSP1(42) where two putative N-linked glycosylation sites in the FVO sequenc...
The most common isoforms of amyloid-β (Aβ) proteins are composed of 40 or 42 amino acid residues. While Aβ-(1-40) is the predominant species, Aβ-(1-42) is more fibrillogenic and neurotoxic, suggesting that Aβ-(1-42) plays a critical role in the initiation of amyloid fibril formation. We investigated the mechanisms by which soluble Aβ-(1-40) associates with preformed Aβ-(1-42) seeds. A paramagne...
A graph G is divisible by a H if the characteristic polynomial of that H. In this paper, necessary and sufficient condition for recursive graphs to be path used show H-shape P2,2;n−42,n−7, known (for n large enough) minimizer spectral radius among order diameter n−5, determined its adjacency spectrum only n≠10,13,15.
