    Abstract Objective To understand the current status of application of depth of anesthesia (DoA) monitors used by anesthesiologists in China and evaluated its validity. Methods Chinese anesthesiologists who have been licensed as medical practitioners were selected as the research objects. A nationwide online survey was carried out by sending a WeChat survey form to 12 750 anesthesiologists during July and September 2020, and the data of DoA monitor usage and effectiveness were collected. Finally, 4 037 valid questionnaires were obtained. The survey data were analyzed using SPSS 26.0 software. The data were expressed as proportions with 95% confidence interval (CI), and Chi-square test was conducted for statistical analysis. Results ① Only 9.1% of anesthesiologists routinely used DoA monitors in clinical anesthesia. Anesthesiologists in teaching hospitals [proportion of very familiar: 30.3% (28.3%~32.3%)] and grade-A tertiary hospitals [proportion of very familiar: 28.8% (27.1%~30.6%)] were more familiar with DoA monitors than those in non-teaching hospitals [proportion of very familiar: 14.8% (13.2%~16.4%)] and non-grade-A tertiary hospitals [proportion of very familiar: 11.8% (10.1%~13.5%)], respectively. Among the participants, 65.4% of them considered that the 3 electroencephalogram parameters of DoA monitors were equally important, with the proportion of anesthesiologists in teaching hospitals [66.7%(64.7%~68.7%)] higher than that in non-teaching hospitals [64.1%(62.0%~66.2%)], though no statistical difference due to 95%CI overlapping. ② 96.5% of anesthesiologists believed that the DoA monitors could effectively monitor DoA. However, there was no significant difference in anesthesiologists' evaluation of the effectiveness of different DoA monitors. ③ Anesthesiologists with different titles believed that DoA monitors were indispensable for different general anesthesia methods, but statistical difference was seen in whether DoA monitors were required for general anesthesia preserving spontaneous respiration (P < ...

    Abstract Many Canadians use nicotine products such as cigarettes and e-cigarettes. A particular subpopulation of concern is post-secondary students given they have a higher prevalence of use. Many correlates of cigarette smoking and e-cigarette use have been identified. However, less focus has been on examining the correlates of cigarette smoking, e-cigarette use and dual use. This study explores the correlates of different nicotine modality use in post-secondary students. Using data from the Canadian Campus Wellbeing Survey (CCWS;

    Abstract Recent advances in deep learning have significantly improved the ability to infer protein sequences directly from protein structures for the fix-backbone design. The methods have evolved from the early use of multi-layer perceptrons to convolutional neural networks, transformers, and graph neural networks (GNN). However, the conventional approach of constructing K-nearest-neighbors (KNN) graph for GNN has limited the utilization of edge information, which plays a critical role in network performance. Here we introduced SPIN-CGNN based on protein contact maps for nearest neighbors. Together with auxiliary edge updates and selective kernels, we found that SPIN-CGNN provided a comparable performance in refolding ability by AlphaFold2 to the current state-of-the-art techniques but a significant improvement over them in term of sequence recovery, perplexity, deviation from amino-acid compositions of native sequences, conservation of hydrophobic positions, and low complexity regions, according to the test by unseen structures, "hallucinated" structures and diffusion models. Results suggest that low complexity regions in the sequences designed by deep learning, for generated structures in particular, remain to be improved, when compared to the native sequences.

    Abstract Objective: Pancreatic cancer is a devastating and lethal malignancy. Our study investigated the effective mechanism of HNF4G on pancreatic cancer cell functions through the IGF2BP2 transcription.
    Methods: HNF4G and IGF2BP2 expressions in pancreatic cancer were examined. The relationship between HNF4G expression and pancreatic cancer patients' clinicopathological characteristics was evaluated. After interfering with HNF4G expression in pancreatic cancer cells, the cell proliferative, migratory, and invasive capabilities were evaluated. Also, the expression of proliferation-related gene PCNA and migration and invasion-related gene MMP2 was determined. The binding relation between HNF4G and HNF4G promoter was forecasted and testified. A tumorigenesis assay in nude mice was performed to detect the HNF4G interference's effect on the subcutaneous tumorigenic capacity of pancreatic cancer cells.
    Results: HNF4G and IGF2BP2 expressions were up-regulated in pancreatic cancer. Specifically, interfering with HNF4G inhibited PANC-1 cell proliferative, invasive and migratory behaviors, and decreased PCNA and MMP2 expression. Mechanistically, HNF4G as a transcription factor could specifically bind to IGF2BP2 and promote its expression. Rescue assay findings showed that IGF2BP2 overexpression could reverse the inhibiting effect of HNF4G interference on pancreatic cancer cells. For the in vivo finding, interfering HNF4G expression retarded the subcutaneous tumorigenic ability of pancreatic cancer cells.
    Conclusion: We summarize that HNF4G as a transcription factor regulates IGF2BP2 expression to promote pancreatic cancer cell proliferation and migration capacities.

    Abstract Due to substrate layers with different substrate configurations, extensive green roofs (EGRs) exhibit different rainfall runoff retention and pollution interception effects. In the rainfall runoff scouring process, nutrient leaching often occurs in the substrate layer, which becomes a pollution source for rainwater runoff. In this study, six EGR devices with different substrate layer configurations were fabricated. Then, the cumulative leaching quantity (CLQ) and total leaching rate (TLR) of NH

    Abstract Given the challenges for the experimental determination of RNA tertiary structures, probing solvent accessibility has become increasingly important to gain functional insights. Among various chemical probes developed, backbone-cleaving hydroxyl radical is the only one that can provide unbiased detection of all accessible nucleotides. However, the readouts have been based on reverse transcription (RT) stop at the cleaving sites, which are prone to false positives due to PCR amplification bias, early drop-off of reverse transcriptase, and the use of random primers in RT reaction. Here, we introduced a fixed-primer method called RL-Seq by performing RtcB Ligation (RL) between a fixed 5'-OH-end linker and unique 3'-P-end fragments from hydroxyl radical cleavage prior to high-throughput sequencing. The application of this method to

    Abstract Objectives: Hypertrophic cardiomyopathy (HCM) is the most common hereditary cardiomyopathy and immune infiltration is considered an indispensable factor involved in its pathogenesis. In this study, we attempted to combine bulk sequencing and single-cell sequencing to map the immune infiltration-related genes in hypertrophic cardiomyopathy.
    Methods: The GSE36961, GSE160997, and GSE122930 datasets were obtained from the Gene Expression Omnibus database. The compositional patterns of the 18 types of immune cell fraction and pathway enrichment score in control and HCM patients were estimated based on the GSE36961 cohort using xCell algorithm. The Weighted Gene Coexpression Network Analysis (WGCNA) was performed to identify genes associated with immune infiltration for hypertrophic cardiomyopathy. The area under the curve (AUC) value was obtained and used to evaluate the discriminatory ability of common immune-related DEGs. "NetworkAnalyst" platform was used to identify TF-gene and TF-miRNA interaction with identified common genes. Heat map was used to determine the association between common DEGs and various immune cells.
    Results: Immune infiltration analysis by the xCell algorithm showed a higher level of CD8+ naive T cells, CD8+ T cells, as well as a lower level of activated dendritic cells (aDC), dendritic cells (DC), immature dendritic cells (iDC), conventional dendritic cells (cDC), macrophages, M1 macrophages, monocytes, and NKT cell in HCM compared with the control group in GSE36961 dataset. aDC, macrophages, and M1 macrophages were the top three discriminators between HCM and control groups with the area under the curve (AUC) of 0.907, 0.867, and 0.941. WGCNA analysis showed that 1258 immune-related genes were included in four different modules. Of these modules, the turquoise module showed a pivotal correlation with HCM. 13 common immune-related DEGs were found by intersecting common DEGs in GSE36961 and GSE160997 datasets with genes from the genes in turquoise module. 5 hub immune-related genes (S100A9, TYROBP, FCER1G, CD14, and S100A8) were identified by protein interaction network. Through analysis of single-cell sequencing data, S100a9, TYROBP, FCER1G, and S100a8 were mainly expressed by infiltrated M1 proinflammatory cells, especially Ccr2-M1 proinflammatory macrophage cells in the heart immune microenvironment while Cd14 was expressed by infiltrated M1 proinflammatory macrophage cells and M2 macrophages in transverse aortic constriction (TAC) mice at 1 week. Higher M2 macrophage and M1 proinflammatory macrophage infiltration as well as lower Ccr2-M1 proinflammatory macrophage and dendritic cells were shown in TAC 1week mice compared with sham mice.
    Conclusions: There was a difference in immune infiltration between HCM patients and normal groups. aDC, macrophages, and M1 macrophages were the top three discriminator immune cell subsets between HCM and control groups. S100A9, TYROBP, FCER1G, CD14, and S100A8 were identified as potential biomarkers to discriminate HCM from the control group. S100a9, TYROBP, FCER1G, and S100a8 were mainly expressed by infiltrated M1 proinflammatory cells, especially Ccr2-M1 proinflammatory cells in the heart immune microenvironment while Cd14 was expressed by M2 macrophages in transverse aortic constriction (TAC) mice at 1 week.

    Abstract Given the challenges for the experimental determination of RNA tertiary structures, probing solvent accessibility has become increasingly important to gain functional insights. Among various chemical probes developed, backbone-cleaving hydroxyl radical is the only one that can provide unbiased detection of all accessible nucleotides. However, the readouts have been based on reverse transcription (RT) stop at the cleaving sites, which are prone to false positives due to PCR amplification bias, early drop-off of reverse transcriptase, and the use of random primers in RT reaction. Here, we introduced a fixed-primer method called RL-Seq by performing RtcB Ligation (RL) between a fixed 5′-OH-end linker and unique 3′-P-end fragments from hydroxyl radical cleavage prior to high-throughput sequencing. The application of this method to E. coli ribosomes confirmed its ability to accurately probe solvent accessibility with high sensitivity (low required sequencing depth) and accuracy (strong correlation to structure-derived values) at the single-nucleotide resolution. Moreover, a near-perfect correlation was found between the experiments with and without using unique molecular identifiers, indicating negligible PCR biases in RL-Seq. Further improvement of RL-Seq and its potential transcriptome-wide applications are discussed.
