the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...

background: finding a suitable method for rapid, accurate and reliable estimation of absorbed dose has high priority in management of the radiation exposed persons. shortly after radiation exposure, apoptosis is a major detriment in proliferative tissues such as the hematopoietic system. therefore, quantification of apoptosis in these tissues could be useful for rapid estimation of radiation ex...

the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...

Difficulties in cognitive control including inhibitory control (IC) are related to the pathophysiology of several psychiatric conditions. In healthy subjects, IC efficiency in childhood is a strong predictor of academic and professional successes later in life. The dorsal anterior cingulate cortex (ACC) is one of the core structures responsible for IC. Although quantitative structural character...

Inhibitory control (IC) is a core executive function that enables humans to resist habits, temptations, or distractions. IC efficiency in childhood is a strong predictor of academic and professional success later in life. Based on analysis of the sulcal pattern, a qualitative feature of cortex anatomy determined during fetal life and stable during development, we searched for evidence that inte...

aim and background: it has since long been known that there is strong relation between   psychological status and functional gastrointestinal disorders (fgid). however, until recently, the nature of this putative relationship was unclear due to a lack of non-invasive methods to investigate the neurobiological mechanisms underlying this relationship.  functional brain imaging has provided a meth...

kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. this report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. after a short period of casting, the case was fully recovered within one year. the signal change w...

OBJECTIVE To investigate whether the diffusion tensor imaging-derived metrics are capable of differentiating the ischemic penumbra (IP) from the infarct core (IC), and determining stroke onset within the first 4.5 hours. MATERIALS AND METHODS All procedures were approved by the local animal care committee. Eight of the eleven rats having permanent middle cerebral artery occlusion were include...
