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...

In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...

ectopic cervical thymus (ect) is an essentially benign condition that is identified during the development of the thymus, and is rare among the adult population. thymic hyperplasia is another thymus-associated condition, which is known to occur secondary to hyperthyroidism. a 39-year-old woman with hyperthyroidism presented with an enlarging submandibular mass, which was diagnosed as a benign h...

purpose: suitable magnetic resonance imaging (mri) techniques from conventional to new devices can help physicians in diagnosis and follow up of multiple sclerosis (ms) patients. the aim of present research was to compare effectiveness of fluid attenuation inversion recovery (flair) sequence of conventional mri and diffuse weighted imaging (dwi) sequence as a new technique in detection of brain...

nowadays, scientific c findings in the field of regeneration of nervous system have revealed the possibility of stem cell based therapies for damaged brain tissue related disorders like stroke. furthermore, to achieve desirable outcomes from cellular therapies, one needs to monitor the migration, engraftment, viability, and also functional fate of transplanted stem cells. magnetic resonance ima...

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...

we present a case report of bupropion-induced diplopia in a 26-year-old woman who suffered from atypical depression. âfter four weeks of taking bupropion (225 mg per day) she complained of headaches, blurred vision, and diplopia. no neurological and ophthalmologic abnormal signs were found. her brain magnetic resonance imaging (mrï) and magnetic resonance venography (mrv) were normal as well. â...
