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 ...

We present a new bound for the worldvolume actions of branes with a Wess-Zumino term. For this we introduce a generalization of calibrations for which the calibration form is not closed. We then apply our construction to find the M-5-brane worldvolume solitons in an AdS background that saturate this bound. We show that these worldvolume solitons are supersymmetric and that they satisfy differen...

background: alzheimer’s disease (ad) is characterized by progressive neuronal loss in hippocamp. epidermal neural crest stem cells (epi-ncsc) can differentiate into neurons, astrocytes and oligodendrocytes. the purpose of this study was to evaluate the effects of transplanting epi-ncsc into ad rat model. methods: two weeks after induction of ad by injection of amyloid-β 1-40 into ca1 area of ra...

mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...

Background: Alzheimer's disease (AD) is the most common disorder of dementia, which has not been cured after its occurrence. AD progresses indiscernible, first destroy the structure of the brain and subsequently becomes clinically evident. Therefore, the timely and correct diagnosis of these structural changes in the brain is very important and it can prevent the disease or stop its progress. N...

Introduction: To study the effect of gallic acid (GA) on hippocampal long-term potentiation (LTP) and histological changes in animal model of Alzheimer disease (AD) induced by betaamyloid (Aβ). Methods: Sixty-four adult male Wistar rats (300±20 g) were divided into 8 groups: 1) Control (Cont); 2) AD; 3) Sham; 4-7) AD+GA (50, 100, and 200 mg/kg for 10 days, orally) or...

the role of transforming growth factor (tgf)-β1, interferon (ifn)-γ, interleukin (il)-2, il-3, and il-6 in the pathogenesis of alzheimer's disease (ad) has long been reported in literature. in this case-control study, the concentrations of these cytokines in altered t lymphocytes, as well as serum vitamin b12, have been compared in terms of factors such as, age, the clinical course and the pati...

in the world history, from ancient times up to now, the plague has been followed by heavy casualties on human societies and social order. one of the deadliest plagues is the great plague of the middle ages, or so-called black death. this plague, in the eighth and ninth ah (fourteenth and fifteenth century ad) swept over some large areas of asia, especially the middle east, as well as europe, an...
