OBJECT Peripheral nerve injury in a limb usually causes intrahemispheric functional reorganization of the contralateral motor cortex. Recently, evidence has been emerging for significant interhemispheric cortical plasticity in humans, mostly from studies of direct cortical damage. However, in this study, a long-range interhemispheric plasticity was(More)
To investigate the usefulness of 18F-FP-CIT PET for assessing the severity of Parkinson's disease (PD) at various clinical stages, 41 patients with PD were divided into early (Hoehn&Yahr I-II, n = 23) and advanced (Hoehn & Yahr III-IV, n = 18) subgroups. 18F-FP-CIT PET was performed in these patients and 12 normal subjects. 18F-FP-CIT uptake in striatal(More)
OBJECTIVES Anorexia nervosa (AN), a disorder of unknown etiology, has the highest mortality rate of any psychiatric disorder. Drawing the brain metabolic pattern of AN may help to target the core biological and psychological features of the disorder and to perfect the diagnosis and recovery criteria. In this study, we used 18F-FDG PET to show brain(More)
In recent years, X-ray computed tomography (CT) is becoming widely used to reveal patient's anatomical information. However, the side effect of radiation, relating to genetic or cancerous diseases, has caused great public concern. The problem is how to minimize radiation dose significantly while maintaining image quality. As a practical application of(More)
Current diagnosis of Major depressive disorder (MDD) depends on its clinical symptoms, not on the results of any laboratory examinations. Establishing biological markers for diagnosis of MDD is one of the most important problems to be solved in psychiatry practice. MDD patients (n=8) and a healthy control group (n=8) were recruited in this study. Hamilton(More)
OBJECTIVE The purpose of this article is to analyze the expression of Glut-1 and HK-II, the association between their expression and 18F-FDG accumulation in pancreatic cancer. METHODS Fifty patients with histologically proven pancreatic cancer were included in this preliminary study, all of whom received 18F-FDG PET/CT performance before surgery.(More)
OBJECTIVE To evaluate the therapeutic effect of autologous transplantation of Schwann cells as "bridge" between the medial forebrain bundle (MFB) and caudate nucleus, into the brain of hemiparkinsonian monkey. METHODS Six monkeys were used following 6-OHDA-induced hemiparkinsonism. Three of them were autologous transplanted using Schwann cells as(More)
