Background and purpose: Sesame oil (SO) is known to have antioxidant and anti-inflammatory properties and may produce protective effects against ischemic stroke-induced brain injuries. We examined the effects of treatment with SO on cerebral infarction and edema in a rat model of ischemic stroke. Materials and methods: Thirty male Sprague Dawley rats were divided into sham, ischemic, and isch...

BACKGROUND There is considerable variation in progressive brain volume changes in schizophrenia. Whether this is related to the clinical heterogeneity that characterizes the illness remains to be determined. This study examines the relationship between change in brain volume over time and individual variation in psychopathology, as measured by five continuous symptom dimensions (i.e. negative, ...
Studies show evidence of longitudinal brain volume decreases in schizophrenia. We studied brain volume changes and their relation to symptom severity, level of function, cognition, and antipsychotic medication in participants with schizophrenia and control participants from a general population based birth cohort sample in a relatively long follow-up period of almost a decade. All members of th...
Neuroimaging findings have proposed that some brain regions including the precuneus, posterior cingulate, and medial prefrontal cortex play an essential role of a structural core in the brain. Network organization endures rapid alterations in development with changes in axonal synaptic connectivity, white matter volume, and the thickness of corresponding cortical regions. Structural maturation ...
The chimpanzee fetuses used in our study showed a significant agerelated change in brain volume over the course of the study period (Figure 1B,C). The volume of the chimpanzee brain increased nonlinearly from 14 to 34 weeks of gestation (F = 634.28; cubic effect, p < 0.0001) (Figure 1C). The brain volume of the chimpanzee was only half that of the human fetus at 16 weeks of gestation (15.8 cm3;...

Background and Aim: Brain tumors have remained as a significant cause of morbidity and mortality and are often refractory to treatment. The grading of brain tumor has an important implication in clinical management. Currently, magnetic resonance spectroscopy (MRS) is an important dimension in evaluating metabolites and grading brain tumors. The aim of this study is to evaluate metabolites in br...
PURPOSE The purpose of this study was twofold: first, to compare two different measures of lesion burden in patients with multiple sclerosis (MS), the magnetization transfer ratio (MTR) histogram and T2 lesion volume; and, second, to investigate the relationship between lesion burden and atrophy in patients with MS. METHODS Thirty patients with MS were examined with MR imaging, including fast...
