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...

The HA-1 lectin isolated from Botrylloides leachii has an amino acid composition similar to that of mammalian serum amyloid protein (SAP). SAP is a universal component of mammalian amyloid deposits. Like SAP, HA-1 has a disc ultrastructure, and antibody to HA-1 binds both (a) to amyloidlike fibers deposited between rejected Botrylloides colonies and (b) to cerebral amyloid deposits in Alzheimer...

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 above pr...

High plasma levels of apolipoprotein A-I (apoA-I) correlate with cardiovascular health, whereas dysfunctional apoA-I is a cause of atherosclerosis. In the atherosclerotic plaques, amyloid deposition increases with aging. Notably, apoA-I is the main component of these amyloids. Recent studies identified high levels of oxidized lipid-free apoA-I in atherosclerotic plaques. Likely, myeloperoxidase...

∑ Serum amyloid A protein (SAA) is an acute-phase plasma protein, which increases in response to tissue damage. The aim of the study was to investigate SAA in the blood of patients with cerebral infarction. Sixty subjects were studied, including 45 patients with cerebral infarction and 15 controls. SAA was determined using ELISA method on days 1, 3, 7 and 14 after ischemic stroke onset. SAA was...

To assess acute-phase proteins in relation to ageing, we measured serum concentrations of C-reactive protein of AGP in 131 healthy elderly individuals (aged >/= 65 years) living independently in the community, and 47 healthy younger individuals. Concentrations of CRP in the older persons (median = 3.0 microg/ml) were significantly greater than in the younger group (median = 0.9 microg/ml, p = 0...

Haptoglobin (Hp) and serum amyloid A (SAA) are considered as the major acute phase proteins (APPs) in goats. These APPs have been investigated in several studies during the last decade. In most studies, a colorimetric assay for Hp and a solid phase sandwich ELISA for SAA have been used for quantification. In 2015, reference intervals for APPs were determined using a new type of assay, the compe...

The importance of serum amyloid A protein in the progression of renal failure was studied over three years in 28 patients with secondary (amyloid A type) amyloidosis predominantly due to rheumatoid arthritis. Creatinine clearance, the amount of protein in the urine, and serum amyloid A and C-reactive protein concentrations were determined regularly. Linear regression analysis showed a close cor...
