This study tests the hypothesis that direct control of nocturnal skin temperature might be applied to improve the disturbed sleep of narcol...
OBJECTIVE Typical changes in spectral electroencephalographic (EEG) activity and heart rate (HR) have been described in periodic leg movements (PLM) associated with or without microarousals (MA). We aimed to determine the effects of sleep stage and wakefulness on these responses to ascertain whether a common pattern of EEG and HR activation takes place. METHODS The time course of EEG spectral...
BACKGROUND Endothelin-converting enzyme (ECE)-1 activates endothelin-1 (ET-1) and may thus contribute to the regulation of vascular tone and cell growth during atherosclerosis. METHODS AND RESULTS To evaluate ECE-1 immunoreactivity concerning big ET-1/ET-1, we performed qualitative and quantitative immunohistochemistry in normal internal mammary arteries (n=10), in coronary arteries with adap...
In order to investigate the effects of rates and nitrogen fertilizer application timing on yield and some growth physiological indices of corn ( Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili during 2009 cropping season. Nitrogen fertilizer levels were arranged in...
