Recent studies suggested that safranal exerts anticonvulsant properties. The present study aimed to investigate the effect of on epileptic activities in amygdala electrical kindling model male rats. Animals were implanted with a recording electrode skull and tripolar amygdala. After 10 days recovery, afterdischarge (AD) threshold each animal was determined stimulated once daily AD for full deve...

1. Noradrenaline, adrenaline and alpha-methylnoradrenaline administration into the nucleus tractus solitarii (NTS) of anaesthetized rats decreased blood pressure and heart rate in a dose-dependent fashion. 2. Bilateral injections were effective in lower doses than unilateral administration. alpha-Methylnoradrenaline given bilaterally produced hypotension in a dose of 0-08 nmol whereas after uni...

pilepsy is a group of heterogeneous neurological disorders characterized by spontaneous and recurrent seizures and is one of the most common that affects 1% of the E Background & Objective: Epilepsy is a chronic neurological disorder in which patients experience spontaneous recurrent seizures. Although the most commonly recommended therapy is drug treatment, some patients do not achieve adequat...

The effects of repeated administration of morphine and methadone, followed by a challenge dose of either morphine or methadone were examined ex vivo in rat frontal cortical slices that were prepared 1 h after final drug administration. Morphine challenge dose (5 mg/kg), administered 14 days after the end of repeated morphine pretreatment (10 mg/kg, administered 7 times) decreased both the AMPA/...

The effect of nitrogen (N14) implant into dual-doped polysilicon gates was investigated. The electrical characteristics of sub-0.25m dual-gate transistors (both pand n-channel), MOS capacitor quasi-static C V curve, SIMS profile, poly-Si gate Rs, and oxide Qbd were compared at different nitrogen dose levels. A nitrogen dose of 5 10 cm 2 is the optimum choice at an implant energy of 40 KeV in te...

The IRay stereotactic low-voltage x-ray irradiation treatment system for age-related macular degeneration consists of a low voltage x-ray tube, an eye tracking system, a robotically controlled delivery system, a coupling device to facilitate tracking and stabilisation, a graphical user interface and gating software. Low-voltage x-rays are delivered in a series of three spots to the macula in a ...

BACKGROUND AND PURPOSE The purpose of our study was to investigate the effects of different doses of neuromuscular electrical stimulation (NMES) on upper-extremity function in acute stroke patients with severe motor deficit. METHODS Sixty-six acute stroke patients were randomized to 3 groups: high NMES, low NMES, or control. The low-NMES group received 30 minutes of stimulation per day, and t...

background: x-ray computed tomography (ct) examinations deliver a significant amount of radiation doses to patients comparing to conventional radiography examinations. the objective of the current study was to analyze and investigate the average patient received dose from axial and spiral ct exams in a medical imaging center. material and methods: in this study, the patient imaging technique, w...

background: the equivalent dose in the human body due to the natural gamma-emitting radionucides (238u, 232th and 40k) in the surface soil surrounding the consolidated tin mine site in bukuru-jos, nigeria has been determined in this study. materials and methods: measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (canberra series 10 plus) coupled ...
