Objectives: Among the diverse forms of amyloidosis, secondary type is the most frequent one. Diagnosis of amyloid deposition is based on the identification of the fibrillary protein amyloid by means of Congo Red (CR) or ...

Amyloids are supramolecular assemblies composed of polypeptides stabilized by an intermolecular beta-sheet core. These misfolded conformations have been traditionally associated with pathological conditions such as Alzheimer's ...

The beta-amyloid peptide (1-42) is a molecule capable of aggregating into neurotoxic structures that have been implicated as potential etiological factors of Alzheimer's Disease. The aim of this study was to evaluate the ...

Alzheimer´s disease is the most widespread form of dementia in the elderly. One of the characteristics of this disease is the profound functional deficit of the cholinergic system as a consequence of synaptic loss. Amyloid ...

The deposition of 4-kDa amyloid beta peptide in the brain is a prominent feature of several human diseases. Such process is heterogeneous in terms of causative factors, biochemical phenotype, localization and clinical ...

The aggregation of proteins into amyloid fbrils is related to more than 30 diseases, including the most common neurodegenerative conditions. Amyloid fbrillation is a nucleation-dependent polymerization reaction where ...

© 2017 Elsevier Inc. Amyloids are polypeptide aggregates involved in many pathologies including Alzheimer's disease. Amyloid assembly is a complex process affected by different interactions including hydrogen bonding, van ...

The self-assembly of two derivatives of KLVFF, a fragment Aβ(16-20) of the amyloid beta (Aβ) peptide, is investigated and recovery of viability of neuroblastoma cells exposed to Aβ (1-42) is observed at sub-stoichiometric ...
