Small-angle X-ray scattering characterization of a $$\beta $$ β -amyloid model in phantoms
BMC Research Notes, 2020 Objective We present a method to prepare an amyloid model at scalable quantities for phantom studies to evaluate small-angle x-ray scattering systems for amyloid detection. Two amyloid models were made from a plasma protein with and without heating. Both

Neurotoxicity of .BETA.-amyloid.
Folia Pharmacologica Japonica, 2000 Recent observations on the neurotoxicity of beta-amyloid have been reviewed and possible roles of racemization of beta-amyloid are discussed. beta 1-40, beta 25-35 and D-Ser26 beta 25-35 (all HCl salt forms), but not commercially available beta 1-40 (TFA salt form), take the beta-structure within few hours in PBS, form fibrils, exert toxic effects on ...

Oxidative stress and the amyloid beta peptide in Alzheimer’s disease
Redox Biology, 2017 Oxidative stress is known to play an important role in the pathogenesis of a number of diseases. In particular, it is linked to the etiology of Alzheimer’s disease (AD), an age-related neurodegenerative disease and the most common cause of dementia in ...

Synapses, synaptic activity and intraneuronal Aβ in Alzheimer's disease
Frontiers in Aging Neuroscience, 2010 β-amyloid peptide accumulation plays a central role in the pathogenesis of Alzheimer’s disease. Aberrant β-amyloid buildup in the brain has been shown to be present both in the extracellular space and within neurons.

Beta-amyloid imaging with florbetaben [PDF]
Clinical and Translational Imaging, 2015 Florbetaben is a fluorine-18 (18F)-labeled stilbene derivative that was developed as a positron emission tomography (PET) tracer for routine clinical application to visualize β-amyloid plaques in the Alzheimer's disease (AD) brain. The tracer successfully completed a global multicenter phase 0-III development program and was, as a consequence, recently

Ectodomain shedding of the amyloid precursor protein: Cellular control mechanisms and novel modifiers [PDF]
, 2006 Proteolytic cleavage in the ectodomain of the amyloid precursor protein (APP) is a key regulatory step in the generation of the Alzheimer's disease amyloid-beta (A beta) pepticle and occurs through two different protease activities termed alpha- and beta-

Acyl peptide hydrolase degrades monomeric and oligomeric amyloid-beta peptide
Molecular Neurodegeneration, 2009 Background The abnormal accumulation of amyloid-beta peptide is believed to cause malfunctioning of neurons in the Alzheimer's disease brain. Amyloid-beta exists in different assembly forms in the aging mammalian brain including monomers, oligomers, and ...

Amyloid-beta and Alzheimer’s disease: the role of neprilysin-2 in amyloid-beta clearance [PDF]
Frontiers in Aging Neuroscience, 2014 Accumulation of the amyloid-beta (Aβ) peptide is a central factor in Alzheimer's disease (AD) pathogenesis as supported by continuing evidence. This review concisely summarizes this evidence supporting a critical role for Aβ in AD before discussing the clearance of this peptide.

DHA supplemented in peptamen diet offers no advantage in pathways to amyloidosis: is it time to evaluate composite lipid diet? [PDF]
PLoS ONE, 2011 Numerous reports have documented the beneficial effects of dietary docosahexaenoic acid (DHA) on beta-amyloid production and Alzheimer's disease (AD).
