OBJECTIVE Schizophrenia and psychotic bipolar disorder have a number of overlapping symptoms and risk factors, but it is not yet clear if the disorders are characterized by similar deviations in brain morphometry or whether any such deviations reflect the impact of shared susceptibility genes on brain structure. The authors used region-of-interest morphometry to volumetrically assess brain stru...
CSF pulsation suggests variation in the size of the cerebral ventricles during the cardiac cycle. The arterial blood flow and venous outflow are two major components that contribute to the variation. High-resolution MR imaging with cardiac gating provides sharp delineation of the cerebral ventricles with clear boundaries. Subtle changes in the size of the ventricles during the cardiac cycle are...
in the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. we have also investigated the structure of neutron stars. according to our results, the spin asymmetry sti ens the equation of state and leads to high mass for the neutron star.
Objective: Frankincense improves memory in different models of learning. However, its influence on models of Alzheimer's disease (AD) has not been studied widely. In the present study, the therapeutic effect of frankincense was evaluated in a model of AD induced by i.c.v administration of streptozotocin. Materials and Methods: Under stereotaxic surgery, two guide cannulas were implanted in the ...
BACKGROUND AND PURPOSE CSF pulsation artifact is a pitfall of fast fluid-attenuated inversion-recovery (FLAIR) brain MR imaging. We studied ventricular CSF pulsation artifact (VCSFA) on axial FLAIR images and its relationship to age and ventricular size. METHODS Fast FLAIR axial images were obtained on a 1.5-T unit (8000/150/2 [TR/TE/ excitations], inversion time = 2200, field of view = 24 cm...
A 33-year-old male presented with a headache. He had a history of a previous surgical procedure for excisions of cervical spine hemangioblastomas 13 years prior He had a family history of von-Hippel Lindau (VHL) disease, and a VHL mutation was identified. Brain magnetic resonance imaging showed enhanced mass lesions in both the third and right lateral ventricles as well as in the cerebellum. Th...
