a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
BACKGROUND Alzheimer disease is a neurodegenerative condition that affects cognitive, behavioral and global functioning of patients. Currently and due to the lack of conclusive biological testing, Alzheimer's disease diagnosis is based primarily on clinical criteria. Since its early diagnosis allows clinical interventions when neurological damage is relatively mild, the development of early det...
alzheimer disease is one form of dementia in old age. alzheimer disease, the incurable disease, which is usually in the seventh decade of human life, shows its symptoms. the disease may be present for years without clinical symptoms. the current study identified the genes with altered expression in patients with alzheimer disease. the important sequence of each gene in alzheimer disease was fou...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
charles dickens was a voracious reader even in his childhood. his early reading of seventeenth- and eighteenth-century picaresque fiction greatly influenced his writing style. his first novel, the pickwick papers, is a tale of rogues and swindlers, adventures and quests, satire and comedy, and innocence and experience. oliver twist, dickens’ second novel, is a young boy’s progress through a cor...
The most popular animal models of Alzheimer’s disease (AD) are transgenic mice expressing human genes with known mutations which do not represent the most abundant sporadic form of the disease. An increasing number of genetic, vascular and psychosocial data strongly support that the Octodon degus, a moderate-sized and diurnal precocial rodent, provides a naturalistic model for the study of the ...
