Software Defined Network (SDN) is revolutionizing the networking industry by a potential of enabling flexible and uniform management by decoupling the control plane and forwarding plane. However, there are several issues on scalability and adaption against conventional network protocols to implement on the large scaled network. To address these issues, we(More)
PURPOSE To evaluate the GABA(A) receptor in the autistic brain, we performed (123)I-IMZ SPECT in patients with ASD. We compared (123)I-IMZ SPECT abnormalities in patients who showed intellectual disturbance or focal epileptic discharge on EEG to those in patients without such findings. SUBJECTS AND METHODS The subjects consisted of 24 patients with ASD(More)
Migrating partial seizures in infancy (MPSI) are an age-specific epilepsy syndrome characterized by migrating focal seizures, which are intractable to various antiepileptic drugs and cause severe developmental delay. We report a case of MPSI with heterozygous missense mutation in KCNT1, which was successfully managed by ketogenic diet. At age 2months, the(More)
Since the neuroradiological features of patients with 22q11.2 deletion syndrome are not well-understood, examinations using functional imaging were performed in this study. Brain magnetic resonance imaging (MRI) and 1H-magnetic resonance spectroscopy (MRS) were performed using a clinical 3-Tesla MR imager in 4 patients with 22q11.2 deletion syndrome (2 boys(More)
PURPOSE To elucidate the functional characteristics of cortical tubers that might be responsible for epilepsy in tuberous sclerosis complex (TSC), proton magnetic resonance spectroscopy ((1)H-MRS) and [123I] iomazenil (123I-IMZ) single photon emission computed tomography (SPECT) were performed. METHODS (1)H-MRS using a clinical 3-tesla magnetic resonance(More)
We previously reported neural dysfunction in the anterior cingulate cortex and dorsolateral prefrontal cortex in autistic patients using proton magnetic resonance spectroscopy ((1)H-MRS). In this investigation, we measured chemical metabolites in the left amygdala and the bilateral orbito-frontal cortex (OFC), which are the main components of the social(More)
We report here an autopsy case, an 8-year-old boy diagnosed as having infantile striatal necrosis, characterized by a preceding febrile illness followed by acute encephalopathy with abrupt obtundation, seizures and dystonia, with remarkable improvement of the disturbed consciousness and intelligence after TRH-T therapy. These clinical symptoms were linked(More)
Using proton magnetic resonance spectroscopy ((1)H-MRS), we measured chemical metabolites in the left amygdala and the bilateral orbito-frontal cortex (OFC) in children with autism spectrum disorders (ASD). The concentrations of N-acetylaspartate (NAA) in these regions of ASD were significantly decreased compared to those in the control group. In the(More)
PURPOSE Proton magnetic resonance spectroscopy (1H MRS) is a noninvasive neuroimaging method to quantify biochemical metabolites in vivo and it can serve as a powerful tool to monitor neurobiochemical profiles in the brain. Asperger's syndrome (AS) is a type of autism spectrum disorder, which is characterized by impaired social skills and restrictive,(More)
INTRODUCTION Mutations of SLC35A2 that encodes Golgi-localized Uridine diphosphate (UDP)-galactose transporter at Xp11.23 lead to congenital disorders of glycosylation (CDG). Although patients with CDG generally have diverse systemic symptoms, patients with a SLC35A2 mutation manifest predominantly disorders of the central nervous system (CNS). CASE(More)
