    This pattern of data directly describes the BCE, and represents a potential alternative mechanism that does not require any response crosstalk, and would reinforce a stricter view of the response selection bottleneck model, if true. Over two experiments, we demonstrate that while the BCE is sensitive to ISPC-like effects based on Task1 conflict contingencies, the BCE is insensitive to relationships between particular pairs of stimuli and associated conflict. While ISPC effects can modulate the BCE, they do not generate the BCE. These findings reinforce the current Task2 parallel response activation account of the BCE.Anxiety has consistently been found to potentiate attentional capture by physically salient stimuli, which could be due to enhanced distractor processing, impaired goal-directed attention, or both. At the same time, a recent study demonstrated that a threat manipulation reduces attentional capture by reward-associated stimuli, suggesting that anxiety does not increase distractibility or, otherwise, interfere with the control of attention generally. Here, we experimentally induced anxiety via threat-of-shock in the adaptive choice visual search task to examine whether the experience of threat influences goal-directed attentional control. Participants chose to search through one of two task-relevant colors on each trial, where searching through the less abundant color would be optimal for maximizing performance. Performance was evaluated with and without the threat of unpredictable electric shock. Under threat, participants were more optimal in their visual search and missed fewer targets. Performance improvements were demonstrated on trials that the optimal target color switched, demonstrating that threat is beneficial in adapting to changing attentional demands. Our findings demonstrate that threat can facilitate the efficiency of goal-directed attentional control and are at odds with an antagonistic relationship between anxiety and the control of attention.The importance of phonological awareness (PA) for the acquisition of literacy skills has been widely recognized. Across languages, PA is commonly examined using the Oddity test, however, for Chinese-speaking children, Pinyin invented spelling is recommended as being a more powerful tool to assess PA. However, it is still unclear whether this holds true for learners of Chinese as a second language (CSL). To address this issue, we administered an oddity test and a Pinyin invented spelling task to explore Chinese PA in 43 Arabic and 40 English CSL learners at pre-intermediate and intermediate levels. The results generated two major findings. First, Pinyin invented spelling revealed more significant cross-group differences in Chinese PA between the Arabic and English CSL learners than the oddity test. Second, the participants’ performance in Pinyin invented spelling was a stronger predictor of character-reading and character-writing skills than their performance in the oddity test. The overall findings suggest that Pinyin invented spelling may be a more powerful measurement of Chinese PA for CSL learners in comparison to the conventional test, in line with the findings reported for Chinese-speaking children. The theoretical implications for understanding the role of phonological skills in the growth of Chinese literacy skills and practical suggestions for measuring Chinese PA are proposed.In recent years, despite the fact that many researchers have devoted much of their attention to second language attrition, not much focus has been given to first language attrition (FLA) specifically among Iranian immigrants. The present study attempts to describe FLA in the semantic domain of idiomatic expression and effect of length of residence among Persian native speakers who live in Iran as well as those who migrate to English-speaking countries. The present study explores language attrition in three migrant populations (Persians in the United States, Australia, and Canada). The participants were selected through convenience sampling. Furthermore, to find the impact of length of residence, the immigrants were divided into two groups comprising short- and long-term residence groups. The instrument applied by the researchers for data collection included a researcher-devised idiomatic expression test to assess immigrants’ level of idiom comprehension and demographic information questionnaire to have a better understanding of immigrants’ background characteristics. Results revealed that the immigrants underwent FLA and the rate of attrition was higher in long-term immigrants. The results are in harmony with the Activation Threshold Hypothesis showing the language attrition among fewer L1 users. The finding of this study sheds new light on the understanding of the concept of first language attrition in migration studies.OBJECTIVE The objectives of this research project were isolation, identification, and evaluation of the safety aspect and probiotics properties of 21 Enterococcus faecium strains isolated from sausages originated from southeastern Serbia. RESULTS Analyzed E. faecium isolates showed tolerance to simulated gastrointestinal conditions. All the examined isolates grew well on media with 0.1% and 0.2% of phenol. None of the tested isolates were histamine-producers, while the synthesis of tyramine was observed for E. faecium sk8-1 and sk8-17. Full resistance to antibiotics was not observed for any examined isolate of E. faecium (penicillin, amoxicillin, and ofloxacin showed the effect on all tested isolates). An inhibition zone against examined pathogens was exhibited by all strains, with the largest inhibition zone against Pseudomonas spp., Proteus spp. and E. coli (12-30 mm/MIC values ranged from 0.5 to 12 mg mL-1). selleck kinase inhibitor CONCLUSION The results indicated that E. faecium isolates from spontaneously fermented sausage showed a potential for further investigation and possible application as probiotics.OBJECTIVE The purpose of this study is to investigate whether mechanical growth factor (MGF) promotes mechanical response to ligament fibroblasts in osteoarthritis knee cavity via activating transcription factor 2 (ATF-2). RESULTS Osteoarthritis ligament fibroblasts (OA-LFs) were suffered from 12% static mechanical stretch to mimic mechanical force mediated ligament injury. Meanwhile, OA-LFs were treated with MGF before and during mechanical stretch. We observed that OA delayed LFs response to mechanical injury, while MGF pretreatment promoted cells timely feedback the mechanically stimuli by inducing cellular stress. Additionally, MGF accelerated the ligament injury repair by promoting cell migration, decreasing the MMP-2 activity, and remitting the cell deformation via ATF-2 activating in cells. CONCLUSIONS Our study shows that MGF pretreatment of OA-LFs can respond quickly to mechanical damage and repair ligament tissue by activating ATF-2. Therefore, MGF has potential as a therapeutic for OA patients.
