“…This result was similar to that of previous studies (Liu et al, 2009; Chung et al, 2010). Interestingly, when the participants were unaware of the stimuli, a P2 reversal (scrambled words > neutral words) was exhibited.…”

“…P2 was investigated in a time-window of 220–280 ms and was calculated as mean amplitude (Chung et al, 2010; Liu et al, 2013). We defined a mid-line ROI to test the P2 component (from five mid-line electrode sites: Fz, FCz, Cz, CPz, and Pz; Yun et al, 2011).…”

“…Finally, at the time window around 250 ms after stimulus onset, there exists a positive-going wave (P250) at the whole brain, which is related to both automatic semantic processing and early word recognition (García-Larrea et al, 1992; Kim et al, 2001; Hill et al, 2002; Liu et al, 2009). For example, Chung et al (2010) have found the P250 reflects that semantic memory network is activated in the semantic processing of Chinese words.…”

Automatic Processing of Emotional Words in the Absence of Awareness: The Critical Role of P2

It has been long debated to what extent emotional words can be processed in the absence of awareness. Behavioral studies have shown that the meaning of emotional words can be accessed even without any awareness. However, functional magnetic resonance imaging studies have revealed that emotional words that are unconsciously presented do not activate the brain regions involved in semantic or emotional processing. To clarify this point, we used continuous flash suppression (CFS) and event-related potential (ERP) techniques to distinguish between semantic and emotional processing. In CFS, we successively flashed some Mondrian-style images into one participant's eye steadily, which suppressed the images projected to the other eye. Negative, neutral, and scrambled words were presented to 16 healthy participants for 500 ms. Whenever the participants saw the stimuli—in both visible and invisible conditions—they pressed specific keyboard buttons. Behavioral data revealed that there was no difference in reaction time to negative words and to neutral words in the invisible condition, although negative words were processed faster than neutral words in the visible condition. The ERP results showed that negative words elicited a larger P2 amplitude in the invisible condition than in the visible condition. The P2 component was enhanced for the neutral words compared with the scrambled words in the visible condition; however, the scrambled words elicited larger P2 amplitudes than the neutral words in the invisible condition. These results suggest that the emotional processing of words is more sensitive than semantic processing in the conscious condition. Semantic processing was found to be attenuated in the absence of awareness. Our findings indicate that P2 plays an important role in the unconscious processing of emotional words, which highlights the fact that emotional processing may be automatic and prioritized compared with semantic processing in the absence of awareness.

“…Ubiquitin-protein ligase E3A (UBE3A), also known as E6AP ubiquitin-protein ligase (E6AP) is an enzyme synthetized by the UBE3A gene, which is located on chromosome 15 (Xiong et al, 2000;Chung et al, 2010) and its relationship with inflammation and cancer has been widely investigated. The maternal UBE3A gene can be normally expressed, while the paternal gene cannot be expressed because of antisense RNA interference produced by the adjacent SNRPN gene (Gyenes et al, 2010;Britschgi et al, 2012).…”

ABSTRACT. Renal carcinoma accounts for a fifth of the morbidity among malignant tumors in China. Ubiquitin-protein ligase E3A (UBE3A) plays an important role in the occurrence and development of gene mutation-induced diseases. This study was designed to investigate the mechanism of Liguistium wallichii in treating renal carcinoma. Hematoxylin and eosin staining was applied to detect the pathological changes in a rat renal carcinoma model. The experimental group received L. wallichii treatment at 100 mg/kg every 48 h for 4 weeks, while the control group only received normal saline. The proliferation index Ki67 was measured by immunohistochemistry. Primary renal carcinoma cells were isolated and UBE3A expression was measured by quantitative polymerase chain reaction. The related signaling pathway was screened by the Pathway Finder Array. pP65 nuclear import was detected by immunofluorescence. A total of 60 rats were used for the renal carcinoma model, of which 58 rats were successfully established and equally divided into two groups: L. wallichii and normal saline. Ki67 expression decreased in the L. wallichii group and was upregulated in the normal saline group. Histological analysis showed significant renal cell nucleus division in the normal saline group. The UBE3A level decreased after L. wallichii treatment compared to the level in the normal saline group. The Pathway Finder Array revealed that the NF-κB signaling pathway was activated, and pP65 presented obvious nuclear import in the normal saline group. In conclusion, L. wallichii inhibits renal carcinoma progression by downregulating UBE3A and suppressing the NF-κB signaling pathway.

“…However, whether this is also the case for compound words is less clear, as morphemes in compound words are relatively separable and easy to identify (Chung et al, 2010). On the one hand, morphological decomposition seems to offer a very effective route for compound word comprehension.…”

The present study investigated the electrophysiological correlates of morphological processing in Chinese compound word reading using a delayed repetition priming paradigm. Participants were asked to passively view lists of two-character compound words containing prime-target pairs separated by a few items. In a Whole Word repetition condition, the prime and target were the same real words (e.g., , manager-manager). In a Constituent repetition condition, the prime and target were swapped in terms of their constituent position (e.g., , the former is a pseudo-word and the later means nurse). Two ERP components including N200 and N400 showed repetition effects. The N200 showed a negative shift upon repetition in the Whole Word condition but this effect was delayed for the Constituent condition. The N400 showed comparable amplitude reduction across the two priming conditions. The results reveal different aspects of morphological processing with an early stage associated with N200 and a late stage with N400. There was also a possibility that the N200 effect reflect general cognitive processing, i.e., the detection of low-probability stimuli.
