Small-angle X-ray scattering characterization of a $$\beta $$ β -amyloid model in phantoms

open access: yesBMC 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

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

High Glycemic Diet Is Related to Brain Amyloid Accumulation Over One Year in Preclinical Alzheimer's Disease

open access: yesFrontiers in Nutrition, 2021
Objective: To test the hypothesis that high glycemic diet is related to 1-year change in brain amyloid based on our prior cross-sectional evidence that high glycemic diet is associated with brain amyloid.Methods: This longitudinal, observational study ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Neuronal Apoptosis Induced by β-Amyloid Is Mediated by Caspase-8

open access: yesNeurobiology of Disease, 1999
The Alzheimer disease-associated β-amyloid peptide has been shown to induce apoptotic neuronal death. In the present study, we test the hypothesis that the apoptotic pathway activated by β-amyloid is similar to the pathway activated by the Fas/TNFR ...

The A4 study: β‐amyloid and cognition in 4432 cognitively unimpaired adults

open access: yesAnnals of Clinical and Translational Neurology, 2020
Objective To clarify the preclinical stage of Alzheimer’s disease by estimating when β‐amyloid accumulation first becomes associated with changes in cognition.

The Amyloid-β Oligomer Hypothesis: Beginning of the Third Decade

open access: yesJournal of Alzheimer's Disease, 2018
The amyloid-β oligomer (AβO) hypothesis was introduced in 1998. It proposed that the brain damage leading to Alzheimer’s disease (AD) was instigated by soluble, ligand-like AβOs.

Neuropsychiatric Symptoms Mimicking Dementia in a Patient Treated With Imatinib

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Tyrosine kinase inhibitors are the cornerstone of chronic myeloid leukemia treatment. Newer agents have more potency and a broader spectrum of action, but also a higher potential for neuropsychiatric side effects. We present a case of a patient on imatinib who developed progressive cognitive, mood, and behavioral alterations.

Unique pharmacological property of ISRIB in inhibition of Aβ-induced neuronal cell death

open access: yesJournal of Pharmacological Sciences, 2016
A pharmacological approach to ameliorate Alzheimer's disease (AD) has not yet been established. In the present study, we investigated the pharmacological characteristics of the recently identified memory-enhancing compound, ISRIB for the amelioration of ...

Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.
