BACKGROUND Although several previous studies have been conducted, the neural basis of autism spectrum disorder (ASD) is poorly understood. The objective of the present study was to determine whether individuals with ASD have altered brain chemical metabolites and whether such alterations are related to their autistic symptoms. METHODS N-acetylaspartate(More)
OBJECT The goal of this study was to investigate the usefulness of proton (1H) magnetic resonance (MR) spectroscopy to evaluate the response of metastatic brain tumors to stereotactic radiosurgery (SRS) in comparison with Gd-enhanced MR imaging and single-photon emission computerized tomography with administration of thallium-201 chloride (201TlCl-SPECT).(More)
OBJECT The authors of previous studies based on diffusion tensor imaging have indicated that there are two types of peritumoral edema-namely, edema with preserved structural integrity of the glial matrix and edema with compromised glial matrix. The authors of this study hypothesized that functionality of the glutamate (Glu)-glutamine shuttle, a vital(More)
A transient (lasting for 15 min) bilateral carotid artery occlusion model was created by using male Mongolian gerbils ( n=20, weight 50-60 g). The animals were divided into a group with mild hypothermia (34 degrees C, n=10) and a normothermic group (37 degrees C, n=10). High-energy phosphate metabolism (ATP, PCr, Pi) and intracellular pH were sequentially(More)
A 51-year-old female presented with a rare case of choroid plexus papilloma originating in the sella turcica manifesting as headaches that was not readily distinguishable preoperatively from pituitary adenoma. Head magnetic resonance imaging revealed a tumor extending from the sella turcica to the suprasellar cistern. The tumor was removed via an endonasal(More)
OBJECTIVE Surgical site infection(SSI)is commonly seen following spinal surgery, and it can be associated with serious morbidity, mortality, and increased resource utilization. The objective of this study was to identify specific independent risk factors for SSI occurring after spinal surgery. METHODS We performed a retrospective study of patients who had(More)
An 18-year-old male presented with a chondroma in the petrous apex manifesting as major complaints of headaches and sensorineural hearing disturbance on the right. Head computed tomography and magnetic resonance imaging revealed a neoplastic lesion in the right petrous apex, which had bulged to compress the internal auditory meatus. Surgical removal(More)
LactoSorb fixation plates are made of a bioabsorbable polymer (82% poly-L-lactic acid and 18% polyglycolic acid), and the strength is not inferior to titanium plates. LactoSorb has been used in the fields of pediatric neurosurgery and facial plastic surgery. Cranial fixation in craniotomy is mostly performed using titanium plates and clamps, but there are(More)
