Microwave assisted synthesis of the Cu(I) compound [Cu(µ₄-4-ptz)]n [1, 4-ptz=5-(4-pyridyl)tetrazolate] has been performed by employing a relatively easy method and within a shorter period of time compared to its sister compounds. The syntheses of the Cu(II) compounds [Cu₃(µ₃-4-ptz)₄(µ₂-N₃)₂(DMF)₂]n∙(DMF)2n (2) and [Cu(µ₂-4-ptz)₂(H₂O)₂]n (3) using a similar method were reported previously by us....

In the present study, we investigated the effects of vagus nerve stimulation (VNS), a proposed treatment for patients with intractable epilepsy, on cardiac rhythm following seizures induced by pentylenetetrazole (PTZ) in Wistar rats. After a baseline recording of electroencephalogram (EEG), electrocardiogram (ECG) and blood pressure (BP), rats in the first group received a single convulsive dos...

It has been described that febrile seizures during infancy increase risk of subsequent non-febrile seizures during the adulthood. However, latency period between febrile seizure and the onset of the first spontaneous seizure has not been evaluated. The present study was designed to investigate the susceptibility to subsequent seizures in immature rats that had experienced early-life hyperthermi...

BACKGROUND It has been reported that epilepsy is a disorder of the central nervous system that causes memory impairment. This study examines the role of the aqueous extract of Boswellia on the learning disability of the pentylenetetrazol (PTZ)-induced kindled rats. METHODS In this experimental study, 64 male rats were used. Kindling seizures were induced by three injections of 25 mg/kg of PTZ...

OBJECTIVE At present, there are many antiepileptic drugs with a wide range of side effects on the human body. It was assumed that Zataria multiflora Boiss (Z. multiflora) with sedative, anti-spasmodic and anti-inflammatory activity may be effective in the treatment of epilepsy. The aim of the present study was to elucidate the effect of Z. multiflora hydroalcoholic extract and its fraction extr...

The consequences of photoexcitation of a platinum diimine bisacetylide complex and its triads with phenothiazine species (McGarrah, J. E.; Eisenberg, R. Inorg. Chem. 2003, 42, 4355-4365) were investigated by the photoinduced transient displacement current (PTDC) method, with the aim of understanding the role of solvent in defining the nature and extent of intratriad electron transfer. PTDC enab...

As a surveillance camera for the security of urban area, a single pan-tilt-zoom (PTZ) camera has been used. For effective application of the video sequence of the single PTZ camera, accurate orientation or calibration of the video sequence is needed. This paper proposes a mathematical model based on the collinearity condition equation for relative orientation estimation between frames from vide...

Brain-derived neurotrophic factor (BDNF) and c-Fos are shown to promote epileptogenesis and are taken as a marker of neuronal activity. The present study investigated the expression of BDNF and c-Fos in mice brain with pentylenetetrazol- (PTZ-) induced generalized seizure and evaluated the effect of novel tryptamine derivative HHL-6 on the expression of these two markers. The subconvulsive dose...

OBJECTIVE(S) A growing interest has recently been attracted towards the identification of plant-based medications including those with protective effects against cognitive impairment. Sesamol has shown promising antioxidant and neuroprotective effects, therefore, we aimed to evaluate its therapeutic potential in epilepsy which is commonly associated with oxidative stress and cognitive impairmen...

There are several lines of evidence that opioidergic and nitrergic systems could modulate the seizure threshold. We previously have shown that sildenafil had proconvulsant effects in a model of clonic seizure induced by pentylenetetrazole (PTZ) or bicuculline. In the present study, we examined whether the opioid system participates in the action of sildenafil on the PTZ-induced clonic seizures ...
