statement of problem: impacts and accidents are considered as the main fac- tors in losing the teeth, so the analysis and design of the implants that they can be more resistant against impacts is very important. one of the important nu- merical methods having widespread application in various fields of engineering sciences is the finite element method. among its wide applications, the study of ...

Introduction: The central-governor model explains the mechanism of endurance exercise-induced central fatigue, but high-intensity exercise-induced central fatigue has not been investigated yet. This study aimed to research how central fatigue during high-intensity intermittent pedaling alters the neural response, which results in electroencephalography (EEG) recordings. Methods: We assessed ne...

introduction: barrel cortex of rats is a part of somatosensory cortex, which receives information from facial whiskers. vibrisectomy by sensory deprivation leads to some changes in the barrel cortex, which have been known as experience dependent plasticity. on the other hand, norepinephrine (ne) and locus coeruleus, which is the main source of ne, influenced response properties of cortical barr...

patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (melas) present with recurrent and partially reversible neurological deficits. lesions of melas classically cause a signal change in both the grey and white matter, predominantly in the occipital and parietal lobes. these lesions mimic infarction. here, we reported a case of melas with rare neuroimaging finding...
