introduction: alzheimer’s disease (ad) is one of the most common neurodegenerative disorders, which has much benefited from animal models to find the basics of its pathophysiology. in our previous work (haghani, shabani, javan, motamedi, & janahmadi, 2012), a non-transgenic rat model of ad was used in electrophysiological studies. however, we did not investigate the histological aspects in the ...

Abstract Background Here, we investigated the contribution of education and regional amyloid as potential de‐ accelerators in spread tau pathology. Method 85 amyloid‐positive subjects (age=76.80±1.08, education=16.70 ±.50 years, M/F=42/43) were included, for whom [18F]AV‐1451 PET at two timepoints, baseline [18F]AV‐45 PET, ApoE‐status clinical information available ADNI. PETs intensity‐standard...

abstract   introduction: neurodegeneration change is one of the hallmark symptoms of which alzheimer’s disease (ad) can be modeled by β-amyloid injection into specific regions of brain. (-)-epigallocatechin-3-gallate (egcg) is a potent antioxidant agent that its role against oxidative stress and inflammation has been shown in prior studies. in the present study, we have wanted to determine whet...

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...

Progressive cognitive decline is one of the hallmark symptoms of Alzheimer’s disease (AD) which can be modeled by β-amyloid injection into specific regions of brain. Since epigallocatechin-3-gallate (EGCG) is a potent antioxidant agent which its role against oxidative stress and inflammation has been shown in prior studies, we tried to determine whether EGCG administration protects against β-am...

Amyloid-β (Aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in Alzheimer’s disease pathology.Uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. Aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

Background & Aims: Alzheimer's disease is a neurodegenerative disorder characterized by the abnormal aggregation of amyloid-β plaques in the brain. Although several studies have been done for finding effective medicines in the treatment of this disease, a drug that inhibits amyloid β aggregation and ameliorates the disorder has not been approved so far. One important therapeutic approach is use...
