本研究旨在瞭解在COVID-19線上教學期間教師情緒勞務中的淺層展現與深層展現對自我效能感的影響，並檢視教學正念於淺層展現與深層展現對自我效能感影響關係的調節效果。研究方法為問卷調查法，研究對象為於新冠疫情期間具線上教學經驗之臺灣國小教師，有效樣本為644份。研究使用多元迴歸分析進行假設檢驗。研究結果發現，因COVID-19疫情採線上教學期間，教師淺層展現程度愈高，則自我效能感愈低；教師深層展現程度愈高，則自我效能感愈高，本研究進一步發現教學正念對深層展現影響自我效能感的加乘效果不顯著、正念程度高的教師在進行淺層展現時對自我效能感的降低程度與正念程度低的教師無顯著差異。本研究建議學校聘請專家進行教師情緒調控之培訓課或鼓勵教師參與相關研習課程，多採深層展現進行教學，提升教師自我效能感。 Introduction Following its outbreak in 2019, the COVID-19 pandemic caused a considerable shift in work patterns across multiple industries. Taiwan continued education through online platforms, maintaining a “no suspension of classes” approach to ensure uninterrupted teaching and student learning. However, this transition imposed challenges on teachers, many of whom faced substantial stress and anxiety due to the demands of online teaching. Accordingly, this study focused on emotional labor, specifically surface acting and deep acting, as antecedent variables. During online teaching, teachers must maintain a strong belief in and enthusiasm for teaching to effectively foster student engagement and learning outcomes. The present study selected teacher self-efficacy as its outcome variable and explored the effects of surface acting and deep acting on teacher self-efficacy in the context of online teaching. The relevant literature suggests that mindfulness in teaching can enhance the effectiveness of teaching strategies and mitigate emotional exhaustion in teachers, thereby warranting its inclusion as a moderating variable in this study. Relevant studies have indicated that surface acting in emotional labor diminishes individual well-being and lowers self-efficacy, whereas deep acting enhances individual well-being and increases self-efficacy. Furthermore, deep acting positively predicts classroom management self-efficacy, whereas surface acting negatively affects such self-efficacy. However, these findings are based on traditional face-to-face teaching methods and lack support from empirical research regarding the relationships among teachers’ surface acting, deep acting, and self-efficacy during the online teaching period prompted by the COVID-19 pandemic in Taiwan. Additionally, understanding of the moderating role of teaching mindfulness in the relationships among surface acting, deep acting, and teacher self-efficacy remains limited. Accordingly, this study aimed to determine (1) how teacher surface acting and deep acting influence teacher self-efficacy in the context of online teaching during the COVID-19 pandemic and (2) the moderating role of teaching mindfulness in the relationships among teacher surface acting, deep acting, and self-efficacy. Research Purpose This study examined how teacher emotional labor affected teacher self-efficacy during the online teaching period prompted by the COVID-19 pandemic in Taiwan and investigated the moderating role of teaching mindfulness in the relationship between teacher emotional labor and self-efficacy. The aim of this study was to clarify the differential effects of surface acting and deep acting on teacher self-efficacy in the context of online teaching. The results of this study are expected to contribute to practical implications for teaching and to suggest timely support and assistance for teachers engaged in online teaching in order to enhance overall teaching effectiveness within school organizations. Data Collection The present research methodology conducted a questionnaire survey targeting primary school teachers in Taiwan with experience of online teaching during the COVID-19 pandemic period. A total of 644 valid responses were collected. The study utilized an English scale from an internationally published journal. To ensure conceptual validity and to avoid any loss of meaning due to translation, a back-translation process was employed. In addition, adjustments were made to some wordings to suit the context of online teaching during the COVID-19 pandemic, and relevant explanations were added accordingly. This study employed the emotional labor scale developed by Diefendorff et al. (2005) to assess teacher surface acting and deep acting during online teaching in the pandemic period. The measurement tool for surface acting consisted of seven items, whereas the measurement tool for deep acting consisted of four items. The Teacher Self-Efficacy Scale developed by Tschannen-Moran and Hoy (2001) was employed to assess self-efficacy among teachers engaged in online teaching. This scale contains three dimensions— namely “Teaching Strategies” (four items), “Classroom Management” (four items), and “Student Engagement” (four items)— yielding a total of 12 items. The Mindfulness in Teaching Scale developed by Frank et al. (2016) was employed to assess teacher mindfulness. This scale comprises eight items across two dimensions: “Intrapersonal Mindfulness” (six items) and “Interpersonal Mindfulness” (two items). Data Analysis IBM SPSS Statistics version 20.0 was used to perform quantitative statistical analysis of the survey data. The data analysis methods utilized in this study included descriptive statistics, Pearson correlation, and multiple regression analysis. Multiple regression analysis was employed to examine how surface acting and deep acting influenced teacher self-efficacy and to investigate the moderating effects of teaching mindfulness. Results The study results revealed that during the period of online teaching prompted by the COVID-19 pandemic, higher levels of surface acting among teachers were associated with lower self-efficacy, whereas higher levels of deep acting were associated with higher self-efficacy. Furthermore, the moderating effect of teaching mindfulness on the relationship between deep acting and self-efficacy was not significant. Finally, no significant difference was found in the reduction of self-efficacy between teachers with high levels of mindfulness who engaged in surface acting and those with low levels of mindfulness. Recommendations At the school level, organizational culture can substantially affect teachers’ emotional labor. Organizations can enhance the substance of a teacher’s job structure while fostering a school culture based on mutual trust and support. These actions are particularly crucial in the context of online teaching, where support for teachers’ instructional efforts is even more essential. Hiring experts to conduct training or relevant workshops related to emotional regulation for teachers can empower educators to apply their professional knowledge to develop personalized emotional expression skills. Such skill development can, in turn, improve teachers’ foundational ability to control their emotions and thus align with external expectations regarding their educational goals. In the context of online teaching, supporting teachers in managing their emotions appropriately and effectively by using emotional labor strategies is crucial for enhancing the effectiveness of online teaching. Suggestions for Future Research Future research should incorporate genuine emotional expression into strategies for emotional labor. Although this study analyzed only teachers from primary schools in Taiwan, it did not specifically analyze numbers of teachers in different regions. Accordingly, future research could investigate the distribution of teachers on the basis of the geographical locations of the primary schools where they teach. Because teachers are embedded within schools and because each school may have unique resources and methods of supporting online teaching, teachers from a single school often share certain common traits. Future research could utilize hierarchical linear modeling to explore relationships among variables at different levels. Finally, this study employed a quantitative research approach, and the self-reported data obtained limited the in-depth understanding of the participants’ performance in emotional labor and self-efficacy. Accordingly, future research is recommended to employ qualitative methods, such as interviews, to collect data and verify the authenticity of self-reported information.

BACKGROUND: Abnormal Notch1 signaling pathway is mostly found in the brain of Alzheimer’s disease patients, but the role of these signaling pathways in the pathogenesis of Alzheimer’s disease has not been fully clarified. Long-term aerobic exercise can alter the expression of Notch1 by affecting the methylation rate of factors related to the Notch1 signaling pathway. However, it is not clear whether aerobic exercise affects hippocampal nerve cell proliferation and histopathological features of Alzheimer’s disease mice through the Notch1 signaling pathway. OBJECTIVE: To observe the effects of aerobic exercise on the proliferation and histopathological features of hippocampal nerve cells in Alzheimer’s disease mice after DAPT inhibited the Notch1 signaling pathway. METHODS: APP/PS1 double transgenic Alzheimer’s disease mice aged 3 months were randomly divided into four groups: control group, exercise control group, inhibitor group, and exercise inhibitor group, with 20 mice in each group. The control group was fed naturally, and the exercise group received aerobic exercise intervention. Both natural feeding and exercise intervention lasted for 20 weeks. The mice were injected with solvent or Notch1 inhibitor at week 18. After 20 weeks, the brain tissue was collected, and Aβ1-42, Tau, Ki67, and Notch1 expression levels were detected by real-time PCR, immunofluorescence, and western blot assay. RESULTS AND CONCLUSION: Compared with the control group, the expressions of Ki67 and Notch1 in the dentate gyrus region of the hippocampus were significantly decreased in the inhibitor group (P < 0.05), but there were no significant differences in Aβ1-42 and Tau. The expression of Ki67 in the dentate gyrus region of the hippocampus in the exercise control group was significantly higher than that in the control group, while the expressions of Aβ1-42, Tau, and Notch1 were significantly lower than those in the control group (P < 0.05). The expressions of Aβ1-42, Tau, Ki67, and Notch1 in the dentate gyrus region of the hippocampus of the exercise inhibitor group were not significantly different from those of the inhibitor group. In conclusion, the Notch1 signaling pathway may mediate exercise to improve the proliferation and histopathological features of hippocampal nerve cells in Alzheimer’s disease mice.

AIM: To investigate the effect of hypericin（ Hyp） on the heart of rats with myocardial ischemia-reperfusion injury （MIRI）, and to explore its mechanism. METHODS: Thirty SPF male SD rats were divided into 5 groups: sham group, MIRI group, low-dose Hyp （L-Hyp） group （MIRI+L-Hyp group）, high-dose Hyp （H-Hyp） group （MIRI+H-Hyp group）, and positive control trimetazidine （TMZ） group （MIRI+TMZ group）, with 6 rats in each group. Apart from the sham group, the MIRI model was established by ligating the anterior descending branch of the left coronary artery and then recanalizing it in the remaining four groups of rats. The success of the modeling was determined by monitoring the electrocardiogram. We assessed the cardiac function in rats using echocardiography. TTC staining was employed to measure the area of myocardial infarction in rats, and HE staining was utilized to observe the morphological traits of rat myocardium. We assayed the activities of lactate dehydrogenase （LDH） and superoxide dismutase （SOD） and the levels of malondialdehyde （MDA） in rat serum using biochemical kits. ELISA kits were applied to assess the contents of cardiac troponin I（ cTnI） and reactive oxygen species（ ROS） in rat serum. Western blot analysis was perfomed to measure the protein expression levels of AMPK, p-AMPK, Nrf2, and HO-1 in rat myocardial tissues. RESULTS: The rats in MIRI group exhibited increased myocardial tissue injury, larger myocardial infarction areas, decreased left ventricular ejection fraction（ LVEF）, and reduced left ventricular fractional shortening（ LVFS） compared with sham group, as shown by echocardiography. Additionally, there were increases in LDH activity, cTnI, MDA and ROS levels, along with significant decreases in SOD activity, and p-AMPK, Nrf2 and HO-1 protein levels （P<0. 05）. Compared with MIRI group, the rats in MIRI+L-Hyp, MIRI+H-Hyp and MIRI+TMZ groups showed decreased myocardial histopathological damage and reduced myocardial tissue infarction area, increased LVEF and LVFS, and lowered serum levels of LDH activity, cTnI, MDA and ROS, while SOD activity, p-AMPK, Nrf2 and HO-1 protein levels were elevated（ P<0. 05）. CONCLUSION: Hypericin attenuates myocardial ischemia-reperfusion injury in rats, possibly by modulating the AMPK/Nrf2/HO-1 signaling pathway. [ABSTRACT FROM AUTHOR]

To investigate the effects of microbial agents on the maturation indicators and bacterial communities during the composting process of chicken manure, this study used chicken manure as the raw material and mushroom residue as the auxiliary material for aerobic composting. Two groups of experiments were set up: microbal agents treatment group and control group. The physicochemical indicators, seed germination index, and the structure and diversity of microbial communities during the composting process were compared. The results showed that at the end of the composting, the pH values for the control group and test treatment group were 8.37 and 8.70, respectively, the electrical conductivity values were 1.86 mS·cm-1 and 1.67 mS·cm-1, respectively, and the moisture content was 43.25% and 34.35%, respectively. Compared with the control group, test group reduced nitrogen loss rate by 28.65 percent points, and the seed germination index at the end of the composting was 115.18%, which was higher than the control group′ s 94.83%. High-throughput sequencing analysis revealed that the addition of microbial agents improved altered the composition of the composting bacterial communities, which contributed to the maturation of compost, and inhibited the growth of some conditional pathogens. The study demonstrates that the addition of microbial agents influenced the bacterial community structure of chicken manure compost, reduced nitrogen loss in the compost pile, and enhanced the maturity of the compost.

Objective To investigate the clinical features and prognostic factors of pediatric acute lymphoblastic leukemia with hyperleukocytosis (HL-ALL). Methods The clinical data of 427 newly diagnosed ALL children admitted to the Department of Hematology and Oncology of Kunming Children’s Hospital from January 2019 to July 2022 were retrospectively analyzed. According to the initial white blood cell count (WBC) of 100×109 /L, the children were divided into the hyperleukocytosis group and the non-hyperleukocytosis group. The clinical characteristics, major laboratory tests, overall survival (OS) and event-free survival (EFS) were compared between the two groups. Results There were 250 males and 177 females, with a male-to-female ratio of 1.41∶1. There were 92 cases (21.5%) in the hyperleukocytosis group and 335 cases (78.5%) in the non-hyperleukocytosis group. Compared with the non-hyperleukocytosis group, the hyperleukocytosis group had significantly higher proportions of children aged < 1 year and > 10 years, T lymphoblastic leukemia (T-ALL), moderate to severe hepatosplenomegaly, and high-risk risk (P < 0.05), as well as significantly higher percentage of immature cells at initial diagnosis, serum uric acid (UA) level, and lactate dehydrogenase (LDH) level (P < 0.05). The platelet count (PLT) and the proportion of hyperdiploidy at diagnosis were lower (P <0.05). The 3-year EFS and OS of the hyperleukocytosis group were lower than those of the non-hyperleukocytosis group. WBC ≥100×109 /L at diagnosis, age >10 years, age < 1 year, T-ALL, high-risk, D15 MRD positive, D33 MRD positive, CNSL, MLL rearrangement, and MEF2D rearrangement were independent risk factors for EFS and OS rates in children with ALL (P < 0.05). Conclusion The children with HL-ALL usually have a higher percentage of peripheral blood immature cells, elevated serum UA and LDH, and are often accompanied by age of onset <1 or > 10 years old, TALL, hepatosplenomegaly, and high risk. The early treatment response and prognosis of the children with HL-ALL are poor. [ABSTRACT FROM AUTHOR]
