parkinson’s disease is one of the most common neurodegenerative disorders. there are many documents about the effects of oxidative stress in parkinson’s disease etiology. angiotensin ii activates nadph dependent oxidases and causes superoxides formation. peganum harmala l. extract, which has angiotensin converting enzyme (ace) inhibitory effect, is considered to evaluate oxidative stress inhi...
Cognitive activities and the operation of tasks in the workplaces lead to the creation of a cognitive workload and specifically mental workload employee in the work environment. In order to measure these cognitive variables, physiological parameters are used. Electroencephalography is a non-invasive and relatively inexpensive method that can be used to evaluate neurophysiology and cogniti...
Background and purpose: Traumatic brain injury (TBI) is the leading cause of death in young people. Berberine is a flavonoid rich in barberries and many traditional Iranian herbal remedies that could be used in treatment of neurodegenerative diseases. These properties make it a viable treatment for neurodegenerative diseases. Therefore, this study intended to investigate the neuroprotective ac...
As one of the most important diffused brain modulatory systems, the nucleus locus coeruleus (LC) receives most of its afferents from the nucleus paragigantocellularis (PGi) and plays a major role in the control of drug dependence and some emotional and exciting states. For detailed investigation of the effect of morphine on relationship between these two brain stem nuclei, the activity of the r...
Introduction: resent studies have been shown that normobaric hyperoxia (HO) can induce excitotoxicity and stress oxidative tolerance (ETT) in variety of organs such as brain. In this study, we examined the intermittent dose of normobaric hyperoxia (HO) on neurologic deficit, and superoxide dismutase activity in brain tissue of Huntington animal model. Method: The rats were divided to three...
Introduction: Organophosphate (OP) pesticide is used as chemical warfare nerve agents against both military and civilian population during the Iran–Iraq War. Paraoxon (POX) as an OP acts via the inhibition of cholinesterase and disturbance in body antioxidant systems. The aim of this study was to investigate the effect of N-acetyl cysteine (NAC) as an antioxidant against POX- induced oxid...
Introduction: In recent years, optical imaging has attracted a lot of attention from scholars as a non- aggressive, efficient method for evaluating the activities of the motor cortex in the brain. Functional near-infrared spectroscopy (fNIRS (is a tool showing the hemodynamic changes in a cortical area of the brain according to optical principles. The present study has been de...
