introduction: pneumonectomy is the standard treatment of lung cancer, even though patients should undergo several evaluations before surgery; deterioration of cardiopulmonary function after pulmonary resection is inevitable. we have evaluated the effects of digoxin on the improvement of right ventricular function and prevention of probable complications after lung resection surgery. materials a...

background: to evaluate the patients with stroke by functional independence measure (fim) scale, at the times of admission to hospital, discharge, and six-month poststroke, and to determine the level of improvement in patients after rehabilitative procedures. methods: a total number of 108 patients with stroke entered the study who were admitted to neurology ward. they all received rehabilitati...

purpose our study aimed to profile the effect of fasting during the ramadan month on cognitive function in a group of healthy muslim athletes. methods eighteen male athletes underwent computerized neuropsychological testing during (fasting) and after (non-fasting) ramadan. diet was standardized, and tests were performed at 0900h and 1600h to characterize potential time-of-day (tod) interactions...

introduction: prior studies comparing hemodynamic response function (hrf) in the young and elderly adults based on fmri data have reported inconsistent findings for brain vision and motor regions in healthy aging. it is shown that the averaging method employed in all previous works has caused this inconsistency. the averaging is so sensitive to outliers and noise. however, fmri data are obscure...

purpose the aim of this study was to determine the effect of one night's sleep deprivation on anaerobic performance and reaction time of subjects in the morning of the following day. methods eighteen male college student athletes were studied twice in a balanced, randomized design. subjects were measured for peak power, mean power and reaction time. results the performance showed no significant...

background :aging can cause loss of balance, which may lead to physical and psychological problems. as the role of the otolith organs in maintaining postural stability has been emphasized in recent years, the present study investigated the effect of aging on saccular function using cervical vestibular evoked myogenic potentials (cvemp).   methods : the participants were assigned into two groups...

objective(s):neurotoxicity of anticancer drugs complicates treatment of cancer patients. vinblastine (vbl) is reported to induce motor and cognitive impairments in patients receiving chronic low-dose regimen. materials and methods: the effects of vbl treatment on motor, learning and memory functions of male and female wistar rats were studied by behavioral related tests. animals were given chro...

the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...
