background: chronic daily headache (cdh) has gained little attention in functional neuro-imaging. when no structural abnormality is found in cdh, defining functional correlates between activated brain regions during headache bouts may provide unique insights towards understanding the pathophysiology of this type of headache. methods: we recruited four cdh cases for comprehensive assessments, in...

INTRODUCTION Functional assessment of arterial load by dynamic arterial elastance (Eadyn), defined as the ratio between pulse pressure variation (PPV) and stroke volume variation (SVV), has recently been shown to predict the arterial pressure response to volume expansion (VE) in hypotensive, preload-dependent patients. However, because both SVV and PPV were obtained from pulse pressure analysis...

land mines are one of the tragic problems to human security in many countries. among many techniques suggested detecting landmines, plant-based detectors can be used as a reliable tool for unexploded ordnance detection. this study was conducted to determine different concentrations effect of trinitrotoluene (0, 5, 10, 15, 20, 30, 45 and 60 ppm) on germination and early seedling growth of 6 spec...

Human brain functional networks contain a few densely connected hubs that play a vital role in transferring information across regions during resting and task states. However, the relationship of these functional hubs to measures of brain physiology, such as regional cerebral blood flow (rCBF), remains incompletely understood. Here, we used functional MRI data of blood-oxygenation-level-depende...

The functional response describes how the rate of consumption changes in response to a change in the density of the resource. Since HOLLING’s (1959) seminal study, ecologists have measured and categorized the functional response for a large number of specific consumer-resource relationships (JESCHKE et al. 2002). Functional response curves are ecologically important because they allow inference...
