Frontal alpha asymmetry (FAA) has been explored extensively in affective neuroscience. To determine which FAA indicators are linked with the habitual use of emotion regulation, we recorded the resting electroencephalogram alpha activity. First, we reduced all of the FAA indicators to four factors by exploratory factor analysis. Next, we carried out a multiple regression analysis to determine which factors could significantly predict the habitual use of emotion-regulation strategies. According to the results, greater left-asymmetric activation at the dorsolateral prefrontal cortex predicted increased use of reappraisal, whereas at the ventrolateral prefrontal cortex, it was predicted by right-asymmetric activation. Greater left-asymmetric frontal activity at the posterior dorsolateral prefrontal cortex was related to increased use of distraction and suppression. These results suggest that resting FAA in the prefrontal cortex region plays a significant role in the habitual use of emotion regulation.Video abstract: http://links.lww.com/WNR/A485.

Based upon the intramolecular charge transfer (ICT) mechanism, a novel ratiometric fluorescent probe EB was developed to detect SO32−/HSO3−. The probe displayed both colorimetric and ratiometric responses toward SO32−/HSO3−. It displayed a quick response (within 60 s), good selectivity and high sensitivity (a detection limit of 28 nM) towards SO32−/HSO3−. The SO32−/HSO3− sensing mechanism was confirmed as the Michael addition reaction by ESI-MS. Moreover, the probe could be applied to measure the level of sulfite in real samples, like sugar and chrysanthemum, and it could also be used to detect SO32−/HSO3− in HepG2 cells through confocal fluorescence microscopy, which proved its practical application in clinical diagnosis.

As one typical form of play, play center activities are commonly used in early childhood education programs in China. This study used the Activities Sub-scale of the Chinese Early Childhood Environment Rating Scale (CECERS) to measure the quality of the play center activities in K2 (4-5 years old) classroom, which based on a stratified random selection of 48 classrooms in Guangdong Province in China. Results found that the overall quality of play center activities was slightly below qualified (5 points), and there are significant differences between urban and rural, private and public, high and low level of kindergartens. Quality of three dimensions (material and space, opportunity and time, design and organization) also showed a medium level (above 4 points), and significant differences of three dimensions are found between urban and rural, private and public, high and low level of kindergartens. Findings and implications will help teachers to better support and enhance children’s play center activities and early learning.
