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)
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)
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)
BACKGROUND AND AIMS The aim of this study was to investigate the early changes of cardiac uncoupling protein-2 (UCP2) expression following myocardial ischemia reperfusion in rats chronically treated with ramiprilat and losartan. METHODS Male Wistar rats were assigned into seven groups (six in each): intact (control); sham-operated; nontreated rats(More)
Normal human breathing exhibits complex variability in both respiratory rhythm and volume. Analyzing such nonlinear fluctuations may provide clinically relevant information in patients with complex illnesses such as asthma. We compared the cycle-by-cycle fluctuations of inter-breath interval (IBI) and lung volume (LV) among healthy volunteers and patients(More)
