    Abstract The present study proposes a novel deep-learning model for remote sensing image enhancement. It maintains image details while enhancing brightness in the feature extraction module. An improved hierarchical model named Global Spatial Attention Network (GSA-Net), based on U-Net for image enhancement, is proposed to improve the model's performance. To circumvent the issue of insufficient sample data, gamma correction is applied to create low-light images, which are then used as training examples. A loss function is constructed using the Structural Similarity (

    Abstract Atherosclerosis (AS) is one of the main risk factors of ischemic cardiovascular and cerebrovascular diseases. Buyang Huanwu decoction (BYHWT) is a classic Chinese medicine prescription that is used for treating AS. However, the underlying pharmacological mechanism remains unclear. This study aims to clarify the molecular mechanism of BYHWT in treatment of AS through network pharmacology and in vitro experiments. Molecular structure information and targets of core components of BYHWT were obtained from PubChem and UniProtKB databases. Genes involved in AS were obtained from DisGeNet, GeneCards and OMIM databases. The core targets of BYHWT in AS treatment were identified by protein-protein interaction (PPI) network analysis with STRING platform, and analyzed by gene ontology (GO) analysis and the Kyoto Encyclopedia of Genes and Genomics (KEGG) pathway enrichment analysis. Molecular docking was used to verify the binding affinity between the core targets and the bioactive ingredients. HUVEC viability, inflammatory response and mRNA expression levels of core target genes were evaluated by cell counting kit 8 assay, enzyme-linked immunosorbent assay (ELISA) and qRT-PCR. A total of 60 candidate compounds and 325 predicted target genes were screened. PPI network analysis suggested that TP53, SRC, STAT3, and AKT1 may be the core targets. BYHWT in AS treatment was associated with 46 signaling pathways. GA120, baicalein, and 3,9-di-o-methylnissolin had good binding affinity with core target proteins. Baicalein treatment could significantly promoted the viability and repress the inflammatory response of HUVEC cells stimulated by ox-LDL. In addition, Baicalein can regulate the expression of core targets including AKT1, MAPK1, PIK3CA, JUN, TP53, SRC, EGFR, and ESR1. In conclusion, BYHWT and its main bioactive component baicalein, inhibit inflammatory response and modulate multiple downstream genes of endothelial cells, and show good potential to block the progression of AS and cardiovascular/cerebrovascular diseases.

    Abstract Purpose: Breast cancer is the second leading cause of death from cancer among Canadian females. This study aimed to quantify and assess trends in education and income inequalities in the mortality rate of breast cancer in Canada from 1992 to 2019.
    Methods: We constructed a census division-level dataset pooled from the Canadian Vital Death Statistics Database (CVSD), the Canadian Census of the Population (CCP), and the National Household Survey (NHS) to examine trends in education and income inequalities in the mortality rate of breast cancer in Canada over the study period. The age-standardized Concentration index (C) was used to quantify income and education inequalities in breast cancer mortality over time.
    Results: The national crude mortality rate of breast cancer has decreased in Canada from 1992 to 2019, with Alberta, British Columbia, Manitoba, Ontario, Prince Edward Island, and Quebec having the greatest decreases in mortality rate. The age-standardized C for education and income inequalities were always negative for all the study years, meaning that the mortality rate of breast cancer was higher among less-educated and poorer females. Moreover, the results indicate a growing trend in the concentration of breast cancer mortality among females with lower income and education from 1992 to 2019.
    Conclusion: The increasing concentration of breast cancer mortality among low socioeconomic status females remains a challenge in Canada. Continuous efforts are needed within Canadian healthcare system to improve the prevention and treatment of breast cancer for this population.

    Abstract Stereolithographic additive manufacturing technology has developed from point-by-point scanning exposure to layer-by-layer masking curing and even volumetric printing. Rapid prototyping is one of the important goals pursued by researchers. A continuous three-dimensional (3D) printing system based on the dual-color photoinitiation and photoinhibition is proposed with the aim of further improving printing speed. The process of continuous 3D printing is realized through the anti-polymerization layer between the cured part and the window generated by the ultraviolet (UV) light sheet (355 nm), and dynamic masking with the blue light (470 nm). The volume of the anti-polymerization layer can be adjusted by the intensity ratio of the incident lights (

    Abstract After resection, abdominal drainage is generally used to drain the exudate at the surgical site timely and monitor possible postoperative complications. With the development of the concept of enhanced recovery after surgery, there is a great controversy about whether to place drainage tube and its retention time after hepatectomy. Based on the research progress at home and abroad, this article reviews whether to place drainage tubes after hepatectomy, commonly abdominal drainage devices in clinical practice, the timing and indications of drainage tube removal, possible complications and preventive measures caused by indwelling drainage tubes, and the improvement effect of intelligent drainage devices on drainage management. The above issues are reconsidered in order to improve the application and management of abdominal drainage after hepatectomy at the level of precision medicine.

    Abstract Background: Indigenous populations have the poorest health outcomes in Canada. In addition, some studies report notable gender health gaps among Indigenous populations of Canada, with greater disadvantages for Indigenous women. To date, the driving factors behind the health gaps between Indigenous women and men are poorly understood.
    Method: Using the four available Aboriginal People Surveys (APS) (2001, 2006, 2012, and 2017), we measure gender gaps in good general health (GGH) (i.e. good/very good/excellent self-rated health) among Indigenous adults (age 18 and above) living off-reserve in Canada. We apply the Oaxaca-Blinder (OB) decomposition method to identify the relative contribution of health endowments and the return to these endowments to the gender health gaps among Indigenous peoples.
    Results: Indigenous men are found to have a higher rate of GGH than their female counterparts. The gender health gap among Indigenous people has somewhat widened over the period 2001 to 2017. The widening of the gender health gap was observed in all four Indigenous identity groups, viz. registered First Nations, non-registered First Nations, Métis, and Inuit. The OB decomposition suggests that differences in endowments such as employment status and income between men and women explain between 30 to 60% of the gender health gap among Indigenous populations in Canada over the study period.
    Conclusion: The social determinants of health appear to be the main factor explaining the gender health gap within the Indigenous peoples living in Canada. Policies improving employment opportunities and income among Indigenous women may potentially reduce the gender health gap within Indigenous population in Canada.

    Abstract Neural activity is costly and requires continuous ATP from aerobic metabolism. Brainstem motor function of American bullfrogs normally collapses after minutes of ischaemia, but following hibernation, it becomes ischaemia-tolerant, generating output for up to 2 h without oxygen or glucose delivery. Transforming the brainstem to function during ischaemia involves a switch to anaerobic glycolysis and brain glycogen. We hypothesized that improving neural performance during ischaemia involves a transcriptional program for glycogen and glucose metabolism. Here we measured mRNA copy number of genes along the path from glycogen metabolism to lactate production using real-time quantitative PCR. The expression of individual genes did not reflect enhanced glucose metabolism. However, the number of co-expressed gene pairs increased early into hibernation, and by the end, most genes involved in glycogen metabolism, glucose transport and glycolysis exhibited striking linear co-expression. By contrast, co-expression of genes in the Krebs cycle and electron transport chain decreased throughout hibernation. Our results uncover reorganization of the metabolic transcriptional network associated with a shift to ischaemia tolerance in brain function. We conclude that modifying gene co-expression may be a critical step in synchronizing storage and use of glucose to achieve ischaemia tolerance in active neural circuits.

    Abstract Cancer has become a global public health problem and its harmful effects have received widespread attention. Conventional treatments such as surgical resection, radiotherapy and other techniques are applicable to clinical practice, but new drugs are constantly being developed and other therapeutic approaches, such as immunotherapy are being applied. In addition to studying the effects on individual tumor cells, it is important to explore the role of tumor microenvironment on tumor cell development since tumor cells do not exist alone but in the tumor microenvironment. In the tumor microenvironment, tumor cells are interconnected with other stromal cells and influence each other, among which tumor-associated macrophages (TAMs) are the most numerous immune cells. At the same time, it was found that cancer cells have different levels of autophagy from normal cells. In cancer therapy, the occurrence of autophagy plays an important role in promoting tumor cell death or inhibiting tumor cell death, and is closely related to the environment. Therefore, elucidating the regulatory role of autophagy between TAMs and tumor cells may be an important breakthrough, providing new perspectives for further research on antitumor immune mechanisms and improving the efficacy of cancer immunotherapy.
