    Abstract Spacer acquisition step in CRISPR-Cas system involves the recognition and subsequent integration of protospacer by the Cas1-Cas2 complex in CRISPR-Cas systems. Here we report an anti-CRISPR protein, AcrVA5, and reveal the mechanisms by which it strongly inhibits protospacer integration. Our biochemical data shows that the integration by Cas1-Cas2 was abrogated in the presence of AcrVA5. AcrVA5 exhibits low binding affinity towards Cas2 and acetylates Cas2 at Lys

    Abstract In the realm of advanced technology, deep learning capabilities are harnessed to analyze and predict novel data, once it has absorbed existing information. When applied to the sphere of education, this transformative technology becomes a catalyst for innovation and reform, leading to advancements in teaching modes, methodologies, and curricula. In light of these possibilities, the application of deep learning technology to teaching resource recommendations is explored in this article. Within the context of the study, a bespoke recommendation algorithm for teaching resources is devised, drawing upon the integration of deep learning and cognitive diagnosis (ADCF). This intricately constructed model consists of two core elements: the Multi-layer Perceptron (MLP) and the Generalized Matrix Factorization (GMF), operating cohesively through stages of linear representation and nonlinear learning of the interaction function. The empirical analysis reveals that the ADCF model achieves 0.626 and 0.339 in the hits ratio (HR) and the Normalized Discounted Cumulative Gain (NDCG) respectively due to the traditional model, signifying its potential to add significant value to the domain of teaching resource recommendations.

    Abstract Objectives: This study aimed to investigate the effect of transfecting SOX2-shRNA vector lentivirus to SACC cell lines on the biological behavior of salivary adenoid cystic carcinoma (SACC)-LM and SACC-83.
    Methods: Three types of SOX2-shRNA lentiviral vectors (817, 818, and 819) were constructed and transfected successfully. The shRNA with the best inhibitory effect was screened out and transfected into SACC cells. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blot were used to detect the expressions of Survivin, E-cadherin, and N-cadherin of SACC-LM and SACC-83. CCK-8 and flow cytometry were used to detect SACC-LM and SACC-83 proliferation and apoptosis. Cell scratch test and Transwell method were used to detect the migration and invasion capabilities of SACC-LM and SACC-83.
    Results: SOX2-shRNA-819 had the best interference effect among the three lentiviruses. After transfecting SOX2-shRNA-819 into SACC-LM and SACC-83, the expressions of SOX2, Survivin, and N-cadherin were significantly reduced, and that of E-cadherin was significantly increased (
    Conclusions: shRNA interference technology reduced SOX2 expression while downregulating Survivin expression. These two expressions may be related. Low SOX2 expression inhibits the proliferation, migration, and invasion of SACC cells and promotes the apoptosis of SACC cells. SOX2 may be involved in the epithelial⁃mesenchymal transition process. This study provided a relevant theoretical basis for targeting SOX2 gene therapy in SACC.

    Abstract The denitrifying anaerobic methane oxidation (DAMO) process plays a crucial role in the global carbon/nitrogen cycles and methane emission control, and also has application potential in biological wastewater treatment. However, given that DAMO microbes are susceptible to external conditions such as additional carbon source in the system, it is essential to evaluate the effect of alternative carbon substance on the enrichment efficiency and metabolic activity of DAMO microbes. To this end, this study investigated the effect of acetate (0.1 mmol/L-R2, 0.5 mmol/L-R3) and biochar addition (R4) on the enrichment and activity of DAMO microbes. The long-term operation showed that the NO

    Abstract The urban carbon cycle is an important part of the global carbon cycle. Clarifying the processes and drivers of the urban carbon cycle is essential for achieving urban carbon neutrality. Research on the urban carbon cycle under various industrial characteristics is still insufficient. In this study, four typical Chinese cities are selected and their carbon cycle processes and influencing factors are analysed. Here we propose an urban carbon neutral rate to evaluate the balance between urban carbon input and carbon output. Through Grey correlation analysis, we explore the main influencing factors of urban carbon neutral rate. The results show that the carbon neutral rate of Chinese cities is uneven and polarised. Heavy industrial cities face major challenges in urban carbon neutrality. In addition, the main factors affecting the carbon neutral rate of cities of different industrial types are not the same. The formulation of urban carbon neutral policies and measures should be differentiated and focused according to the industrial characteristics of cities.
