High resolution evoked potentials (EPs), sampled from 115 channels and spatially sharpened with the finite element deblurring method, were recorded from 8 subjects during working memory (WM) and control tasks. The tasks required matching each stimulus with a preceding stimulus on either verbal or spatial attributes. All stimuli elicited a central P200(More)
OBJECTIVE To investigate the hepatitis E virus (HEV) sensitive cells and its tissue culture conditions. METHODS The HEV from dejecta supernatant of patients with acute hepatitis E was amplified and activated by passaged in Rhesus. Then, the positive dejecta samples of infected monkeys were dealt with super-centrifugation and virus for culture was(More)
High temporal resolution is necessary to resolve the rapidly changing patterns of brain activity that underlie mental function. While electroencephalography (EEG) provides temporal resolution in the millisecond range, which would seem to make it an ideal complement to other imaging modalities, traditional EEG technology and practice provides insufficient(More)
In operational environments that demand sustained vigilance or that involve multiple tasks competing for limited attentional resources, continuous monitoring of the mental state of the operator could decrease the potential for serious errors and provide valuable information concerning the ergonomics of the tasks being performed. There is widespread(More)
OBJECTIVE To analyse the relationship between male infertility and chromosomal translocations, and the influence of different types of chromosomal translocations on semen quality, testicular volume and hormone levels. METHODS A retrospective cohort of infertile men was recruited for chromosomal analysis using standard Giemsa stain banding. Physical(More)
Temporomandibular joint (TMJ) discs frequently undergo degenerative changes in arthritis. However, the biomechanical properties of pathogenic discs remain to be explored. In this study, we evaluated the effects of chronic inflammation on the biomechanical properties of TMJ discs in rats. Chronic inflammation of TMJs was induced by double intra-articular(More)
Successful sperm retrieval from ejaculates of nonmosaic Klinefelter's syndrome (KS) patients by using semen cytology examination was described in this report. The clinical parameters of KS patients with sperm compared to patients without sperm were described. One hundred and fifty-one patients were proven to suffer from KS by chromosomal analysis using(More)
OBJECTIVE To study immunological characteristics of recombinant chimeric HEV antigen. METHODS Constructed recombinant plasmids pThioHisORF(2.1 + 2.2 + 3), which contains three HEV antigen gene fragments (ORF2.1:6287-6403nt, ORF2.2:6743-7126nt, ORF3), was transformed into E. coli and induced with IPTG. Expressed product P(2.1 + 2.2 + 3) existed in(More)
OBJECTIVE To express hepatitis E virus (HEV) ORF3 protein by baculovirus system and provide basis for immunological character research. METHODS Hepatitis E Virus ORF3 gene fragment was obtained by RT-PCR, ligated with vector pThioHisA for sequencing and then inserted into transfected vector pVL1393 to construct recombinant plasmid. Mediated by Lipofectin(More)
