Riluzole has been shown to possess neuroprotective effects in a variety of neurological and animal model of diseases, including motor diseases. However, the mechanism(s) by which riluzole preserves the intrinsic electrophysiological characteristics of neuronal membrane has not been fully delineated. Ataxia is a clinical manifestation of disturbance in(More)
Previous reports have indicated that artificial stimulation of the vagus nerve reduces systemic inflammation in experimental models of sepsis. This phenomenon is a part of a broader cholinergic anti-inflammatory pathway which activates the vagus nerve to modulate inflammation through activation of alpha7 nicotinic acetylcholine receptors (α7nACHR). Heart(More)
The effects of prior treatment of cysteamine, a somatostatin inhibitor, on pentylenetetrazol (PTZ) induced epileptic and plastic changes in CA1 excitability were examined. Population spikes were evoked by activation of Schaffer collaterals with a range of stimulation intensities. Changes in the population spike and epileptiform amplitudes were used as(More)
BACKGROUND It is known that stress alters biological processes. The aim of the present study was to examine the effect of examination stress in young adult male and female students. METHODS Examination stress was studied in 28 young female and 21 young male volunteer students of Rafsanjan university of medical Sciences, 0.5 hour before Physiology(More)
Delayed wound healing is a common complication in diabetes mellitus. From this point of view, the main purpose of the present study is to investigate the effect of extremely low frequency pulsed electromagnetic fields (ELF PEMFs) on skin wound healing in diabetic rats. In this study, diabetes was induced in male Wistar rats via a single subcutaneous(More)
BACKGROUND AND OBJECTIVE Respiratory inductive plethysmography is a non-invasive technique for measuring respiratory function. However, there are challenges associated with using linear methods for calibration of respiratory inductive plethysmography. In this study, we developed two nonlinear models, artificial neural network and adaptive neuro-fuzzy(More)
Using field potential recording in the CA1 region of hippocampal slices from rats injected with cysteamine (200 mg/kg, s.c.), changes in activity and plasticity of Schaffer collateral-CA1 pyramidal cell synapses were examined. Extracellular field potential recording prior to and following either theta-pattern primed bursts (PBs), perfusion with low Mg(2+)(More)
Prior prolonged oxygen exposure is associated with some protection against ischemia-reperfusion (IR) injury to rat brain tissue, but also with toxic effects. We sought to compare the magnitude of protection offered by prolonged and intermittent oxygen pretreatments against IR injury to the rat brain. Rats were divided into four experimental groups, each of(More)
Recent studies suggest that intermittent and prolonged normobaric hyperoxia (HO) results in ischemic tolerance to reduce ischemic brain injury. In this research, we attempted to see changes in excitatory amino acid transporters (EAATs) and TNF-alpha levels following prolonged and intermittent hyperoxia preconditioning. Rats were divided into four(More)
Cardiac cycle is regulated by a complex interplay between autonomic nervous system and cardiac pacemaker cells. Decreased heart rate variability (HRV) and increased cardiac rhythm regularity are associated with poor prognosis in patients with systemic inflammation (e.g., sepsis). However, the underlying mechanism of decreased HRV in systemic inflammation is(More)
