Amyotrophic lateral sclerosis (ALS) is a fatal neurological disease that causes motor neuron degeneration, progressive motor dysfunction, paralysis, and death. Although multiple causes have been identified for this disease, >95% of ALS cases show aggregation of transactive response DNA binding protein (TDP-43) accompanied by its nuclear depletion. Therefore, the TDP-43 pathology may be a conver...
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by death of motor neurons leading to devastating muscle weakness and wasting and weight loss. It causes mixed picture of lower motor neuron (LMN) and upper motor neuron (UMN) dysfunction. The wide spectrums of atypical presentations can frequently lead to expensive work-up and undue delay in diagnosis o...
Introduction: Anesthetic agents, blood pressure, arterial pH and blood gases have found to influence on the pathophysiology of experimental stroke. Despite, there are very few comparative studies about effects of anesthetic agents in animal model of cerebral ischemia. Therefore, in this study, we investigated the effects of chloral hydrate and pentobarbital anesthesia, as comparative study, on...
In spinal muscular atrophy, a neurodegenerative disease caused by ubiquitous deficiency in the survival motor neuron (SMN) protein, sensory-motor synaptic dysfunction and increased excitability precede motor neuron (MN) loss. Whether central synaptic dysfunction and MN hyperexcitability are cell-autonomous events or they contribute to MN death is unknown. We addressed these issues using a stem-...
Multiple muscle agonists and antagonists acting for all the joint movements in the upper and lower limb exist. This redundancy of motor control is very valuable in normal physiology, but when a central nervous system injury with resulting upper motor neuron syndrome takes place, the source of the functional impairment may be difficult to localize. In this paper we discuss the use of gait and mo...
Circadian rhythm is a biological process that regulates neuronal, metabolic, and hormonal functions following 24-hour cycle. Parkinson’s disease (PD) progressive neurodegenerative disorder, it exhibits diurnal fluctuations in motor non-motor symptoms. Recently, increasing attention has been paid to circadian dysfunction PD patients. This review summarizes the existing research on rhythms especi...
UNLABELLED Motor dysfunction in complex regional pain syndrome (CRPS) is often considered a functional movement disorder. Earlier studies in patients with functional movement disorders found evidence of cortical inhibition during explicit but not implicit motor tasks, suggesting active inhibition from other brain areas. In this study, we explored whether active inhibition occurs in CRPS patient...
Spinal muscular atrophy (SMA) is a lethal human disease characterized by motor neuron dysfunction and muscle deterioration due to depletion of the ubiquitous survival motor neuron (SMN) protein. Drosophila SMN mutants have reduced muscle size and defective locomotion, motor rhythm, and motor neuron neurotransmission. Unexpectedly, restoration of SMN in either muscles or motor neurons did not al...
