We used the event-related potential technique to assess the influences of negative emotion on spatial and verbal working memory with a modified n-back task. In both spatial and verbal tasks, the anterior late positive component and the posterior P300 were affected by negative emotion. These effects were, however, greater in spatial tasks than in verbal(More)
We investigated the attentional bias for threat in selected high and low trait-anxious participants using an event-related potential technique. A modified cue-target paradigm was adopted with threatening and nonthreatening pictures as uninformative location cues. In high anxious individuals, reactions were speeded up and the occipitoparietal P1 amplitude(More)
Influenza A virus neuraminidase can be classified into groups 1 and 2 on the basis of its primary structure. The main structural feature of group 1 neuraminidase is an extra cavity in the active site, the 150-cavity. Here we present the crystal structure of neuraminidase from the 2009 pandemic H1N1 influenza strain. In contrast to other characterized N1(More)
MicroRNAs (miRNAs) are small, non-coding RNAs which can function as oncogenes or tumor suppressor genes in human cancers. Emerging evidence reveals that deregulation of miRNAs contributes to the human non-small cell lung cancer (NSCLC). In the present study, we demonstrated that the expression levels of miR-132 were dramatically decreased in examined NSCLC(More)
BACKGROUND Amifostine is the most clinical used chemical radioprotector, but its effect in patients treated with radiation is not consistent. METHODS By searching Medline, CENTRAL, EMBASE, ASCO, ESMO, and CNKI databases, the published randomized controlled trials (RCTs) about the efficacy of amifostine in HNSCC patients treated with radiotherapy were(More)
BACKGROUND The effects of negative emotion on different processing periods in spatial and verbal working memory (WM) and the possible brain mechanism of the interaction between negative emotion and WM were explored using a high-time resolution event-related potential (ERP) technique and time-locked delayed matching-to-sample task (DMST). RESULTS Early P3b(More)
BACKGROUND Hypermethylation of CpG islands in tumor suppressor gene plays an important role in carcinogenesis. Many studies have demonstrated that hypermethylation in promoter region of RARβ gene could be found with high prevalence in tumor tissue and autologous controls such as corresponding non-tumor lung tissue, sputum and plasma of the NSCLC patients.(More)
Although a critical component of taste perception, the neural basis of aftertaste perception has yet to be elucidated with neuroimaging. This functional neuroimaging study assessed the temporal dynamics of neural responses to sucrose and aspartame in eight healthy volunteers. Aspartame has a sweetness flavor profile similar to sucrose but a longer temporal(More)
