Computed tomographic (CT) peritoneography involves CT of the abdomen and pelvis after administration of a mixture of contrast material and dialysate. CT peritoneography can demonstrate a variety of complications of continuous ambulatory peritoneal dialysis. In patients with symptoms of peritonitis, CT peritoneography is better than conventional CT in(More)
Hippocampus learning disturbance is a major symptom of patients with seizure, hence hippocampal dysfunction has essential role in worsening the disease. Hippocampal formation includes neurons and myelinated fibers that are necessary for acquisition and consolidation of memory, long-term potentiation and learning activity. The exact mechanism by which(More)
Accumulating evidence indicates that the brain-gut peptide ghrelin which is expressed in hippocampus improves memory and learning processes. The MK-801, a noncompetitive NMDA receptor antagonist, has also shown amnesic properties in animal model. The current study was to find out whether intracerebroventricular administration of ghrelin can prevent amnesia(More)
Previous studies have shown that Ghrelin increases memory retention. They have also indicated that amygdale is involved in memory storage. The present study examined the role of basolateral amygdala (BLA) in Ghrelin-induced retention improvement, using reversible inactivation of this region with lidocaine. Rats were bilaterally implanted with cannulae at(More)
Chronic diabetes mellitus initiates apoptosis and negatively affects synaptic plasticity in the hippocampus with ensuing impairments of learning and memory. Berberine, an isoquinoline alkaloid, exhibits anti-diabetic, antioxidant and nootropic effects. This study was conducted to evaluate the effect of berberine on hippocampal CA1 neuronal apoptosis,(More)
Previous studies indicated that diabetes affects synaptic transmission in the hippocampus, leading to impairments of synaptic plasticity and defects in learning and memory. Although berberine treatment ameliorates memory impairment and improves synaptic plasticity in streptozotocin (STZ) induced diabetic rats, it is not clear if the effects are pre- or(More)
Cerebral ischemia, which is the second and most common cause of mortality, affects millions of individuals worldwide. The present study was performed to investigate whether intrahippocampal administration of netrin-1 could improve spatial memory impairment in radial arm maze task and restore long-term potentiation (LTP) in 4-vessel occlusion model of global(More)
Unrestricted somatic stem cells (USSCs) loaded in nanofibrous PHBV scaffold can be used for skin regeneration when grafted into full-thickness skin defects of rats. Nanofibrous PHBV scaffolds were designed using electrospinning method and then, modified with the immobilized collagen via the plasma method. Afterward, the scaffolds were evaluated using(More)
The anticonvulsant activities of cannabinoid compounds have been shown in various models of seizure and epilepsy. At least, part of antiseizure effects of cannabinoid compounds is mediated through calcium (Ca2+) channels. The L-type Ca2+ channels have been shown to be important in various epilepsy models. However, there is no data regarding the role of(More)
An oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) nerve conduit has been used to evaluate its efficiency based on the promotion of peripheral nerve regeneration in rats. The oriented porous micropatterned artificial nerve conduit was designed onto the micropatterned silicon wafers, and then their surfaces were modified with oxygen plasma to increase(More)
