PURPOSE Excessive use of the Internet has been linked to a variety of negative psychosocial consequences. This study used resting-state functional magnetic resonance imaging (fMRI) to investigate whether functional connectivity is altered in adolescents with Internet gaming addiction (IGA). METHODS Seventeen adolescents with IGA and 24 normal control(More)
Recent studies suggest that Internet gaming addiction (IGA) is an impulse disorder, or is at least related to impulse control disorders. In the present study, we hypothesized that different facets of trait impulsivity may be specifically linked to the brain regions with impaired impulse inhibition function in IGA adolescents. Seventeen adolescents with IGA(More)
UNLABELLED Abnormalities of frontal white matter (WM) have been found in some children with ADHD. The purpose of this study was to explore the changes in WM in child patients with ADHD by DTI, which detects changes in WM microstructure based on properties of diffusion. We also expect to investigate the relationship between the changes in WM and executive(More)
Although recent studies have clearly demonstrated functional and structural abnormalities in adolescents with internet gaming addiction (IGA), less is known about how IGA affects perfusion in the human brain. We used pseudocontinuous arterial spin-labeling (ASL) perfusion functional magnetic resonance imaging (fMRI) to measure the effects of IGA on resting(More)
OBJECTIVE To explore the neuropsychological characteristics of children with attention deficit hyperactivity disorder (ADHD). METHODS Neuropsychological tests, including visual working memory, Stroop test, digits inverse reciting, vocabulary fluency, Wisconsin card sort test (WCST), and Temporal discounting were used to evaluate the capacity of response(More)
Imaging studies of schizophrenia (SCZ) have repeatedly demonstrated volume differences in superior temporal gyrus (STG) and its subregions. Among them, some studies employed the Region of Interest (ROI) method. We carried out a systematic review of the published literature on STG volumetry MRI studies to examine the potential of ROI method for identifying(More)
ExoS and ExoT are bi-functional type-III cytotoxins of Pseudomonas aeruginosa that share 76% primary amino acid homology and contain N-terminal RhoGAP domains and C-terminal ADP-ribosylation domains. The Rho GAP activities of ExoS and ExoT appear to be biochemically and biologically identical, targeting Rho, Rac, and Cdc42. Expression of the RhoGAP domain(More)
The ubiquitin-proteasome pathway is crucial for a variety of biological processes, including spermatogenesis. Ubiquitin C-terminal hydrolase-L1 (Uch-L1) is thought to associate with monoubiquitin to control ubiquitin levels. Here, we report the identification of Uch-L1 cDNA from the testis of the rice field eel, a natural sex reversal vertebrate, by using(More)
Sustained attention has been proposed as an endophenotype of schizophrenia, and consequently may be useful as a quantitative trait in genetic studies. In the present study, we used the continuous performance test (CPT) to measure sustained attention in 112 first-episode and neuroleptic-naive schizophrenic patients, 296 of their non-psychotic first-degree(More)
Histological and neuroimaging evidence supports the hypothesis that neuronal disconnectivity may be involved in the pathogenesis of schizophrenia. A genome-wide association study (GWAS) showed a single nucleotide polymorphism (SNP), rs10761482 in ankyrin 3 (ANK3), a major neuron-enriched gene, was associated with schizophrenia although inconsistent results(More)
