Ischaemic, excitotoxic and traumatic brain injuries have been associated with the occurrence of epileptic seizures. Microglia, the principal immune cells in the brain, produce a variety of proinflammatory and cytotoxic factors especially interleukin-1 (IL-1) early after an acute insult. We studied the effect of intracerebroventricularly administered(More)
Seizures are common sequel to brain insults in cases such as stroke, trauma and infection where there is a certain neuroinflammation. Intracerebroventricular (i.c.v.) administration of lipopolysaccharide (LPS) induces an inflammatory state in brain that is used as a model of neuroinflammation. We studied the effect of LPS (0.25 and 2.5 microg/rat, i.c.v.)(More)
OBJECTIVE Identification of key molecular changes occurring during epileptogenesis provides better understanding of epilepsy and helps to develop strategies to modify those changes and thus, block the epileptogenic process. Gap junctional communication is thought to be involved in epileptogenesis. This communication can be affected by changes in expression(More)
Understanding the molecular and cellular mechanisms underlying epileptogenesis yields new insights into potential therapies that may ultimately prevent epilepsy. Gap junctions (GJs) create direct intercellular conduits between adjacent cells and are formed by hexameric protein subunits called connexins (Cxs). Changes in the expression of Cxs affect GJ(More)
Morphine produces a state dependent learning. The hippocampus is involved in this kind of learning. Gap junctions (GJs) are involved in some of the effects of morphine and exist in different areas of the hippocampus. We investigated the effects of blocking GJ channels of the hippocampal CA1 area, by means of pre-test bilateral injection of carbenoxolone(More)
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(More)
Gap junction channels are implicated in learning and memory process. However, their role on each of the particular stages of memory formation has been studied less. In this study, the time profile of the expression levels of hippocampal connexins 36 and 45 (Cx36 and Cx45) mRNAs was measured during memory consolidation, in a passive avoidance paradigm.(More)

Aluminium and iron/steel are truly sustainable materials. As a result the global metallurgical industry strives to produce products, which contribute to the global effort by reducing resource use, recycling and reusing materials where possible, and to help create the economic and supply frameworks needed to do this. Aluminium is a material that is(More)
Studies have shown that intracerebral administration of ghrelin hormone affects learning and memory in different experimental models of learning. However, the effect of antagonism of ghrelin receptor type 1a (GHS-R1a) on different stages of learning has not been investigated. In this study the effect of intracerebroventricular (i.c.v) injection of a GHS-R1a(More)
The standards of power system monitoring, control and protection are elevated by Phasor Measurement Units (PMUs) as an auspicious tool. It is the purpose of this paper to determine the optimal number and locations of PMUs so as to make the system measurement model observable and also estimate the power system state. The proposed modelling approach which(More)
