Cardiovascular autonomic dysfunction is a common non-motor symptom associated with synucleinopathies such as Parkinson's disease (PD). Several recent clinical studies indicate that cardiovascular autonomic impairments including orthostatic hypotension and sympathetic denervation may precede the development of the cardinal motor symptoms in PD, making cardiovascular dysfunction an attractive tar...

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 ...

The extent of axonal dysfunction in a group of patients with diabetes mellitus has been investigated using recently introduced quantitative techniques of electromyography. In 40 diabetic patients, estimates of motor unit numbers in the extensor digitorum brevis muscles and measurements of the parameters of electrically evoked motor unit potentials therein are presented, along with significant c...

background: looking in literature reveals that aging is accompanied by olfactory dysfunction and hyposmia/anosmia is a common manifestation in some neurodegenerative disorders. olfactory dysfunction is regarded as non-motor manifestations of parkinson disease (pd). the main goal of this study was to examine the extent of olfactory dysfunction in persian pd patients. methods: we used seven types...

Abundant evidence indicates that mitochondrial dysfunction and Ca(2+) dysregulation contribute to the muscle denervation and motor neuron death that occur in mouse models of familial amyotrophic lateral sclerosis (fALS). This perspective considers measurements of mitochondrial function and Ca(2+) handling made in both motor neuron somata and motor nerve terminals of SOD1-G93A mice at different ...
