OBJECTIVES The thalamus and cerebral cortex are connected via topographically organized, reciprocal connections, which hold a key function in segregating internally and externally directed awareness information. Previous task-related studies have revealed altered activities of the thalamus after total sleep deprivation (TSD). However, it is still unclear(More)
OBJECTIVES Recent neuroimaging studies have identified a potentially critical role of the amygdala in disrupted emotion neurocircuitry in individuals after total sleep deprivation (TSD). However, connectivity between the amygdala and cerebral cortex due to TSD remains to be elucidated. In this study, we used resting-state functional MRI (fMRI) to(More)
PURPOSE Holmium laser enucleation of the prostate (HoLEP) is a well established procedure for the treatment of benign prostatic hyperplasia. Here we report our experience of the learning curve, efficacy, and safety of HoLEP. METHODS We retrospectively reviewed data from 190 consecutive patients who had undergone HoLEP for benign prostatic hyperplasia. The(More)
The enzyme 4-coumarate:coenzyme A ligase (4CL) plays an important role in phenylpropanoid metabolism. The 5′-upstream regions of two Sm4CL genes were isolated from danshen (Salvia miltiorrhiza Bunge) and their functions were characterized by promoter-directed GUS gene expression assay in transgenic Arabidopsis. Seedlings containing pSm4CL1 promoter:GUS(More)
PURPOSE Motion correction in PET has become more important as system resolution has improved. The purpose of this study was to evaluate the accuracy of event-by-event and frame-based MC methods in human brain PET imaging. METHODS Motion compensated image reconstructions were performed with static and dynamic simulated high resolution research tomograph(More)
Despite advances in DNA methylome analyses of cells and tissues, current techniques for genome-scale profiling of DNA methylation in circulating cell-free DNA (ccfDNA) remain limited. Here we describe a methylated CpG tandems amplification and sequencing (MCTA-Seq) method that can detect thousands of hypermethylated CpG islands simultaneously in ccfDNA.(More)
The default mode network (DMN) plays an important role in the physiopathology of schizophrenia. Previous studies have suggested that the cerebellum participates in higher-order cognitive networks such as the DMN. However, the specific contribution of the cerebellum to the DMN abnormalities in schizophrenia has yet to be established. In this study, we(More)
The aim of this study was to review cases of pediatric arterial ischemic stroke among Chinese subjects and thereby evaluate risk factors, clinical and neuroimaging features, and treatment, to establish a reasonable guideline for assessment and management of the disease. Between 1996 and 2006, 157 children (male:female ratio, 1.4:1) with arterial ischemic(More)
Transmission line icing is one of the common disasters in power system. Icing phenomenon is influenced by many external factors, such as climatic condition, voltage degree and so on. Observation is extremely difficult due to these reasons. This paper depicts the design of an on-line monitoring system of transmission line icing based on DSP. The system(More)
A modified multiple endmember spectral mixture analysis (MMESMA) approach is proposed for high-spatial-resolution hyperspectral imagery in the application of impervious surface mapping. Different from the original MESMA that usually selects one endmember spectral signature for each land-cover class, the proposed MMESMA allows the selection of multiple(More)
