A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.

the aim of this study was to compare the effectiveness of fenugreek (trigonella foenum-graecum) with that of lovastatin in restoration of endothelia function in the aorta taken form aged n-mair rats. for this purpose, 4 groups of old n-mari rats were used (n=6), normal saline treated control group, lovastatin (10 mg/kg, orally) and fengreek seed powder in normal saline suspension (100 or 500 mg...

cognitive impairment may be a common even at the onset of multiple sclerosis (ms). in this case-control study, we tried to find out the probable relationship between homocysteine levels and cerebral atrophy or cognitive impairment in patients with multiple sclerosis. one hundred fifty six patients who had ms according to mcdonald diagnostic criteria were included in this study. patients’ age, g...

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...
