Objective: Frankincense improves memory in different models of learning. However, its influence on models of Alzheimer's disease (AD) has not been studied widely. In the present study, the therapeutic effect of frankincense was evaluated in a model of AD induced by i.c.v administration of streptozotocin. Materials and Methods: Under stereotaxic surgery, two guide cannulas were implanted in the ...

Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Therefore, this research study was conducted to evaluate time-dependent changes in passive avoidance and Y-maze performance in male diabetic rats. For this purpose, male Wistar rats were randomly divided into control and diabetic groups. For induction of di...

Background and Objective: Temporal lobe epilepsy (TLE) usually leads to memory deficit. In this study, we tried to assess the effect of Withania somnifera extract on the impaired learning and memory in the intrahippocampal kainate model of TLE in the rat. Materials & Methods: Male rats (n=32) were divided into sham, extract+sham, kainite, and kainite+extract. For induction of epilepsy, unilate...

  Abstract   Introduction: Diabetes mellitus accompanies with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Considering the beneficial antidiabetic potential of Nigella sativum (NS ), this research study was conducted to evaluate the effect of chronic consumption of NS on learning and memory in diabetic rats using passive avoidance and Y-m...

We construct a new harmonic family: dielectric flow solutions with maximal supersymmetry in eleven-dimensional supergravity. These solutions are asymptotically AdS4 ×S7, while in the infra-red the M2 branes are dielectrically polarized into M5 branes. These solutions are holographically dual to vacua of the mass deformed theory on M2 branes. They also provide an interesting insight on the super...

As mentioned before, the success of CASE relies on two noteworthy properties: the Sure Screening (SS) property and the Separable After Screening (SAS) property. In this section, we discuss the two properties in detail, and illustrate how these properties enable us to decompose the original regression problem to many small-size regression problems which can be fit separately. We then use these p...

I describe a modification to Shanks’ baby-step giant-step algorithm for computing the order n of an element g of a group G, assuming n is finite. My method has the advantage of being able to compute n quickly, which Shanks’ method fails to do when the order of G is infinite, unknown, or much larger than n. I describe the algorithm in detail. I also present the results of implementations of my a...

Introduction: S100B is a protein released from astrocytes, which controls neuroglial relationship and probably plays a role in memory and synaptic plasticity. Study of the functional relationship between astrocytes and neurons is of great importance. The present study was conducted to evaluate the effect of S100B infusion into the CA1 region of the hippocampus, on memory performance in male ...
