objective(s): the purpose of the present study was to examine the effects of l-glutamine on electromyographic (emg) activity of the quadriceps muscle injured by eccentric exercise (ee).   materials and methods: seventeen healthy men (age: 22.35±2.27 yr; body mass: 69.91±9.78 kg; height: 177.08±4.32 cm) were randomly and double-blind study with subjects assigned to either an l-glutamine suppleme...

The purpose of this study was to differentiate post-chemoradiotherapy (CRT) changes from tumor persistence/recurrence in early follow-up naso-oropharyngeal carcinoma on magnetic resonance (MRI) with diffusion (DWI) and dynamic contrast-enhanced perfusion-weighted imaging (DCE-PWI). A total 37 patients were assessed MRI both for staging 4-month ending CRT. Mean apparent coefficient (ADC) values,...

conclusions our results indicate that changes in muscle thickness and echo intensity are induced by different inward pressures of the transducer during us. when using a technique that involves a handheld transducer, the examiner should attempt to maintain consistent inward pressure of the transducer during us, to quantify the minimal change of the rf mass and composition. results muscle thickne...

artificial neural networks are used in many smart apparatus and different fields such as signal processing pattern diagnoses, military systems, medicine, financial systems, and artificial intelligence. in this article using quality of neural networks in optimizing energy cost in moving limb and its effectiveness in organization a cognitive function founded by presenting an algorithm for use in ...

background: cardiac syndrome x is a relatively common disorder, and still not much is known about the causative factors or its pathophysiology, which makes it difficult to cure. due to its chronic nature and debilitating symptoms, many patients have significantly reduced quality of life (qol).the purpose of this study was to assess the impact of phase iii cardiac rehabilitation (cr) and relaxat...
