Information-Selectivity of Beta-Amyloid Pathology in an Associative Memory Model

Frontiers in Computational Neuroscience, 2012
This work updates Ruppin and Reggia's associative neural network model of Alzheimer's disease by simulating beta-amyloid pathology and modelling the progression of beta-amyloid throughout the network according to Small's synaptic scaling theory, leading ...

The interaction of amyloid A beta(1-40) with lipid bilayers and ganglioside as studied by P-31 solid-state NMR [PDF]

, 2009
Amyloid P-peptide (A beta) is a major component of plaques in Alzheimer's disease, and formation of senile plaques has been suggested to originate fro m regions of neuronal membrane rich in gangliosides. We analyzed the mode of interaction of A beta with

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Activation of autophagy by Citri Reticulatae Semen extract ameliorates amyloid-beta-induced cell death and cognition deficits in Alzheimer’s disease

Neural Regeneration Research
Amyloid-beta-induced neuronal cell death contributes to cognitive decline in Alzheimer’s disease. Citri Reticulatae Semen has diverse beneficial effects on neurodegenerative diseases, including Parkinson’s and Huntington’s diseases, however, the effect ...

Astrocytic LRP1 mediates brain Aβ clearance and impacts amyloid deposition [PDF]

, 2017
Accumulation and deposition of amyloid-β (Aβ) in the brain represent an early and perhaps necessary step in the pathogenesis of Alzheimer's disease (AD).

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

Time Until Neuron Death After Initial Puncture From an Amyloid-Beta Oligomer [PDF]

arXiv, 2015
Hardy and Higgins first proposed the amyloid cascade hypothesis in 1992, stating that the decrease in neuronal function observed in Alzheimer's Disease (AD) is due to a process initiated by the oligomerization of amyloid-beta peptides. One hypothesis states that toxicity arises from the aggregation of amyloid-beta into a pore structure, which can then ...

Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]

, 2009
The cause(s) of sporadic Alzheimer's disease (sAD) are complex and currently poorly understood. They likely result from a combination of genetic, environmental, proteomic and lipidomic factors that crucially occur only in the aged brain.

Interrelation of inflammation and APP in sIBM: IL-1 beta induces accumulation of beta-amyloid in skeletal muscle. [PDF]

, 2008
Distinct interrelationships between inflammation and beta-amyloid-associated degeneration, the two major hallmarks of the skeletal muscle pathology in sporadic inclusion body myositis (sIBM), have remained elusive.
