introduction: one of the most common markers in alzheimer’s disease (ad) is amyloid beta (aβ) plaques. anti-inflamm-atory agents including phagocytosis by immune cells, proteolytic enzymes and liver are known to decline the risk of aβ plaques formation. in the previous study we showed that aqueous extract of lavandula angusti-folia (lavender) improved memory deficits in alzheimeric rats. here, ...

alzheimer disease (ad) is a neurodegenerative disorder marked by cognitive and behavioral impairment. amyloid beta (aβ) peptides are involved in ad as the main component of amyloid plaques found in the brain. recent in vivo and in vitro studies have shown that there is a lot of substances that alter aβ pathogenesis of ad. aβ induces toxicity lead to increasing ros. in the other hand, 5-ht6 and ...

Proteins that normally function in amyloid form are found bacteria, yeast, plants and vertebrates, including humans. In particular, fibrils amyloid-like structures described the germ cells of various organisms. Recently we showed chicken oocytes there some nuclear stained by amyloid-specific dye thioflavin S. Here demonstrate S binds giant terminal RNP aggregates lampbrush chromosomes. However,...

Background: Extremely low-frequency electromagnetic fields (ELF-EMFs) have gathered significant consideration for their possible pathogenicity. However, their effects on nervous system functions were not fully clarified. In this study, our aim was to assay the effect of ELF-EMFs with different intensity on memory, anxiety, antioxidant activity, beta amyloid (Aβ) deposition and microglia populat...

Objective(s): Vitamin E may have beneficial effects on oxidative stress and Aβ-associated reactive oxygen species production in Alzheimer’s disease. But, the exact role of vitamin E as a treatment for Alzheimer’s disease pathogenesis still needs to be studied. Hence, we examined the therapeutic effects of vitamin E on the density of congophilic amyloid plaques and neur...

Neurological inflammatory diseases are developing rapidly. Different factors involved in the pathogenesis of these diseases. In this article, we discuss some of the mechanisms are dealt with. An aberrant procedure of beta-amyloid precursor protein (BAPP) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (BA) that forms the senile plaque. The ab...

Alzheimer’s Disease (AD) is a progressive neurodegenerative disease and pathologically characterized by the presence of neurofibrillary tangles (tau aggregation) amyloid plaques (amyloid-beta (A

Abstract Repulsive electrostatic forces between prion‐like proteins are a barrier against aggregation. In neuropharmacology, however, prion's net charge ( Z ) is not targeted parameter. Compounds that selectively boost prion remain unreported. Here, we synthesized compounds amplified the negative of misfolded superoxide dismutase‐1 (SOD1) by acetylating lysine‐NH 3 + in amyloid‐SOD1, without na...
