Understanding Mumps Dynamics: Epidemiological Traits and Breakthrough Infections in the Population under 15 Years of Age in Jiangsu Province, China, 2023.

Despite coverage of two doses of mumps-containing vaccines, mumps epidemics persist among children and young adults in China. This study aimed to analyze the epidemiological characteristics of mumps in Jiangsu Province, with a particular focus on breakthrough cases among high-incidence groups. Mumps cases reported in 2023 were systematically collected from the Infectious Disease Surveillance and Reporting System. A comprehensive descriptive epidemiological analysis was performed to elucidate the characteristics of the reported cases. A joinpoint regression (JPR) model was utilized to identify the temporal trends across various periods. Subsequently, immunization information for cases under 15 years of age was obtained through the Jiangsu Province Vaccination Integrated Service Management Information System to identify breakthrough cases and conduct exploratory analyses. A total of 4142 mumps cases were reported in Jiangsu Province in 2023, yielding an annual incidence rate of 4.86/100,000. A total of 81.75% of the cases were students and childcare children, and the gender ratio was 1.5:1 (male/female). The JPR model analysis of weekly reported cases identified five distinct trend segments (1st: 1-8, weekly percent change (WPC) = 26.67 *; 2nd: 9-28, WPC = 3.11 *; 3rd: 29-34, WPC = -5.31; 4th: 35-37, WPC = 15.48; 5th: 38-52, WPC = -4.06 *), and the gender subgroups demonstrated similar trends to the overall pattern. Notably, 89.14% (3692/4142) of the total cases were among individuals under 15 years, with 96.02% (3545/3692) having been vaccinated against mumps. The number of single-dose breakthrough cases (SdBCs) was approximately fourfold (2847/698) that of two-dose breakthrough cases (TdBCs). The main population composition of TdBCs was children aged 0-5 years old, and the classification was dominated by childcare children and scattered children. The median time interval between initial immunization and onset were shorter in TdBCs than in the SdBCs group, and the median time interval between the last immunization and onset was interestingly similarly shorter. However, these situations were interestingly reversed in 105 laboratory-confirmed breakthrough cases. Therefore, the current vaccination strategies have demonstrated tangible effectiveness in preventing and controlling mumps. However, the high incidence of breakthrough cases among high-risk pediatric populations indicates that mumps immunization strategies still deserve more attention and research for better herd protection.

Oral bomb effect nanotherapeutics alleviate ulcerative colitis through coordinated anti-inflammatory and pro-resolving strategies.

Background: Ulcerative colitis (UC) is a debilitating chronic inflammatory bowel disease, and current treatments primarily focus on suppressing inflammation with limited efficacy. However, the resolution of inflammation also plays a crucial role in UC prognosis. Combining anti-inflammatory and pro-inflammatory resolution interventions may be a promising approach for treating UC. Materials and methods: The nano-bomb nanoparticles were validated for their ability to load CD98 siRNA (siCD98) and Annexin A1-mimetic peptides (Ac2-26 peptides), as well as release CO2 upon lysosomal escape. Surface modification with hyaluronic acid (HA) was assessed for its capability to target inflammatory tissues and cells. Biocompatibility and biosafety were evaluated through in vitro and in vivo studies. The anti-inflammatory and pro-resolving effects of siCD98@NPs and Ac2-26@NPs, both individually and in combination, were evaluated by measuring ROS production, pro-inflammatory cytokine expression, CD98 gene expression, and macrophage polarization. Results: These nanoparticles could efficiently load siCD98 and Ac2-26 peptides and release CO2 under acidic pH in the endo/lysosome to deliver drugs to the cytoplasm. HA could effectively target the inflammatory tissue and cells, showing good biocompatibility and biosafety both in vitro and in vivo. siCD98@NPs and Ac2-26@NPs showed anti-inflammatory effects by eliminating the over-production of ROS and down-regulating the expression of pro-inflammatory cytokines (TNF-α and IL-1ß) and the CD98 gene; meanwhile, it showed pro-resolving function by inhibiting M0 to pro-inflammatory M1 macrophage conversion, with a more pronounced effect when combined with siCD98 and Ac2-26. The oral administration of chitosan-alginate hydrogel-encapsulated nanoparticles in UC model mice effectively alleviated inflammatory symptoms, reduced the expression of pro-inflammatory cytokines (TNF-α and IL-1ß) and the CD98 gene, restored intestinal barrier function, and promoted M1 to M2 polarization, with a more pronounced effect when combined. Conclusion: By combining anti-inflammatory and pro-resolution interventions, these nanoparticles offer a novel therapeutic approach. This study offered a new approach for combination therapy of UC.

Association of Maternal Short Sleep Duration With Neurodevelopmental Delay in Offspring: A Prospective Cohort Study.

CONTEXT: To investigate how short sleep duration (SSD) during pregnancy is related to neurodevelopmental delays in offspring, we aimed to inform pregnancy sleep guidelines and promote maternal health and child development. OBJECTIVE: To identify the associations between SSD during pregnancy and offspring neurodevelopmental delay and to determine whether fetal glucose metabolism plays a role in SSD and neurodevelopmental delays. METHODS: This cohort study followed 7059 mother-child pairs from the Maternal & Infants Health in Hefei cohort, and collected sleep data during pregnancy via the Pittsburgh Sleep Quality Index at weeks 24 to 28 and 32 to 36. Neurodevelopmental outcomes from 6 to 36 months postpartum were assessed via the Denver Developmental Screening Test-II and the Gesell Development Diagnosis Scale. Cox proportional hazard regression was used to analyze the link between maternal SSD and neurodevelopmental delay risk. Mediation analysis was used to evaluate the role of cord blood serum C-peptide levels. Three hospitals and children's health centers in Hefei were involved. RESULTS: The stratified analysis revealed a significant association between mothers with SSD during midpregnancy and neurodevelopmental delay in boys (adjusted HR 2.05, 95% CI 1.29, 3.25). Cord blood marker analysis revealed a positive relationship between cord blood serum C-peptide levels and neurodevelopmental delay in offspring (RR 0.04, 95% CI 0.00, 0.08). The proportion of the association between SSD and neurodevelopmental delay mediated by cord blood C-peptide was 11.05%. CONCLUSION: Maternal SSD during pregnancy was continuously associated with an increased incidence of neurodevelopmental delay with sex differences among offspring. This association may be mediated in part by increased higher levels of cord C-peptide.

SleepGCN: A transition rule learning model based on Graph Convolutional Network for sleep staging.

BACKGROUND AND OBJECTIVE: Automatic sleep staging is essential for assessing and diagnosing sleep disorders, serving millions of people who suffer from them. Numerous sleep staging models have been proposed recently, but most of them have not fully explored the sleep transition rules that are essential for sleep experts to identify sleep stages. Therefore, one objective of this paper is to develop an automatic sleep staging model to capture the transition rules between sleep stages. METHODS: In this paper, we propose a novel sleep staging model named SleepGCN. It utilizes the deep features of electroencephalogram (EEG) and electrooculogram (EOG) signals extracted by the sleep representation learning (SRL) module, in conjunction with the transition rules learned by the sleep transition rule learning (STRL) module to identify sleep stages. Specifically, the SRL module utilizes the residual network (ResNet) and Long Short Term Memory (LSTM) structure to capture the deep time-invariant features and temporal information of each sleep stage from the two-channel EEG-EOG, and then applies a feature enhancement block to obtain the refined features. The STRL module employs a Graph Convolutional Network (GCN) and a transition rule matrix to capture transition rules between sleep stages based on the sequence labels of the input signals. RESULTS: We evaluate SleepGCN on five public datasets: SleepEDF-20, SleepEDF-78, SHHS, DOD-H and DOD-O. Overall, SleepGCN achieves an accuracy of 89.70%, 87.70%, 86.16%, 82.07%, and 81.20%, alongside a macro-average F1-score of 85.20%, 82.70%, 77.69%, 72.44%, and 72.93% across these datasets, respectively. CONCLUSIONS: The results achieved by our proposed model are much better than those of all other compared models. The ablation study validates the contributions of the SRL and STRL modules proposed in SleepGCN to the sleep staging tasks. Additionally, it shows that the sleep staging model using two-channel EEG-EOG outperforms the model using single-channel EEG or EOG. Overall, SleepGCN is an effective solution for sleep staging using two-channel EEG-EOG.

Promoting students' autonomous motivation for the ongoing curriculum using a 'Societal Impact Project' with basic psychological needs characteristics.

PURPOSE: Autonomous motivation is important for university students, but it remains a challenge to stimulate their autonomous motivation for their curricula. We developed an extracurricular intervention (Societal Impact Project) with basic psychological needs supportive characteristics such as learning with self-defined problems relevant to curriculum and society, collaborative group work, and coaching by a teacher. This study aims at evaluating the intervention in fostering students' autonomous motivation for their regular curricula. METHODS: We conducted a quasi-experimental study, using between-group pre- and post-test design. Participants from the intervention and control group completed a survey before and after the intervention, which measured the satisfaction of three basic psychological needs, autonomous motivation, controlled motivation, enjoyment, value, and well-being within their regular curricula. We compared the post-test differences between the two groups while controlling for pre-test scores. RESULTS: Students in the intervention group had greater enjoyment in their regular curricula and perceived their regular curricula to have more value compared to students in the control group. The other variables did not differ significantly between the two groups in the post-test. CONCLUSION: The intervention is effective for improving students' enjoyment and perceived value in their regular curricula. The variables with non-significant differences indicate the difficulty to alter students' basic psychological needs and motivation in their regular curricula, even after participating in a long-term intervention.

Orally biomimetic metal-phenolic nanozyme with quadruple safeguards for intestinal homeostasis to ameliorate ulcerative colitis.

BACKGROUND: Ulcerative colitis (UC) is defined by persistent inflammatory processes within the gastrointestinal tract of uncertain etiology. Current therapeutic approaches are limited in their ability to address oxidative stress, inflammation, barrier function restoration, and modulation of gut microbiota in a coordinated manner to maintain intestinal homeostasis. RESULTS: This study involves the construction of a metal-phenolic nanozyme (Cur-Fe) through a ferric ion-mediated oxidative coupling of curcumin. Cur-Fe nanozyme exhibits superoxide dismutase (SOD)-like and •OH scavenging activities, demonstrating significant anti-inflammatory and anti-oxidant properties for maintaining intracellular redox balance in vitro. Drawing inspiration from Escherichia coli Nissle 1917 (EcN), a biomimetic Cur-Fe nanozyme (CF@EM) is subsequently developed by integrating Cur-Fe into the EcN membrane (EM) to improve the in vivo targeting ability and therapeutic effectiveness of the Cur-Fe nanozyme. When orally administered, CF@EM demonstrates a strong ability to colonize the inflamed colon and restore intestinal redox balance and barrier function in DSS-induced colitis models. Importantly, CF@EM influences the gut microbiome towards a beneficial state by enhancing bacterial diversity and shifting the compositional structure toward an anti-inflammatory phenotype. Furthermore, analysis of intestinal microbial metabolites supports the notion that the therapeutic efficacy of CF@EM is closely associated with bile acid metabolism. CONCLUSION: Inspired by gut microbes, we have successfully synthesized a biomimetic Cur-Fe nanozyme with the ability to inhibit inflammation and restore intestinal homeostasis. Collectively, without appreciable systemic toxicity, this work provides an unprecedented opportunity for targeted oral nanomedicine in the treatment of ulcerative colitis.

Unravelling biosynthesis and biodegradation potentials of microbial dark matters in hypersaline lakes.

Biosynthesis and biodegradation of microorganisms critically underpin the development of biotechnology, new drugs and therapies, and environmental remediation. However, most uncultured microbial species along with their metabolic capacities in extreme environments, remain obscured. Here we unravel the metabolic potential of microbial dark matters (MDMs) in four deep-inland hypersaline lakes in Xinjiang, China. Utilizing metagenomic binning, we uncovered a rich diversity of 3030 metagenome-assembled genomes (MAGs) across 82 phyla, revealing a substantial portion, 2363 MAGs, as previously unclassified at the genus level. These unknown MAGs displayed unique distribution patterns across different lakes, indicating a strong correlation with varied physicochemical conditions. Our analysis revealed an extensive array of 9635 biosynthesis gene clusters (BGCs), with a remarkable 9403 being novel, suggesting untapped biotechnological potential. Notably, some MAGs from potentially new phyla exhibited a high density of these BGCs. Beyond biosynthesis, our study also identified novel biodegradation pathways, including dehalogenation, anaerobic ammonium oxidation (Anammox), and degradation of polycyclic aromatic hydrocarbons (PAHs) and plastics, in previously unknown microbial clades. These findings significantly enrich our understanding of biosynthesis and biodegradation processes and open new avenues for biotechnological innovation, emphasizing the untapped potential of microbial diversity in hypersaline environments.

Prenatal exposure to PM2.5 and its composition on child growth trajectories in the first two years: A prospective birth cohort study.

The findings on the relationship between prenatal exposure to particulate matter with aerodynamic diameter ≤2.5 µm (PM2.5) and its constituent and children's growth trajectories are inconsistent. This association's sensitive exposure time window and possible gender differences remain unclear. Our aim was to determine the association between prenatal exposure to PM2.5 and its component and children's growth trajectories by the age of two. From 2015 to 2021, 6407 mother-infant pairs were enrolled in the study. The PM2.5 include sulfate (SO42-), nitrate (NO3-), ammonium (NH4+), organic matter (OM), and black carbon (BC), from the ChinaHighAirPollutants (CHAP) datasets. Children were followed at birth, 1, 3, 6, 9, 12, 18, and 24 months. Population-based and individual-based methods were used to simulate child growth trajectories: slow growth, normal growth, and rapid growth. The distributed lags modeling was used to identify sensitive time windows for the effects of prenatal exposure to PM2.5 and its components on child growth. Sex-stratified analyses estimated sex differences. Median concentrations [interquartile ranges (IQRs)] were 57.46(17.3), 10.59(3.8), 14.26(4.4), 8.69(2.8), 13.05(3.4), and 2.53(0.7) µg/m3 for PM2.5, SO42-, NO3-, NH4+, OM, and BC, respectively. Compared with the normal growth trajectory group, exposure to PM2.5 was significantly associated with a higher risk of rapid growth trajectory in boys (ORs with 95% CI for the entire, first trimester, and second trimester of pregnancy, respectively: 1.016[1.006,1.025], 1.007[1.002,1.011], 1.007[1.002,1.011]). Exposure to PM2.5 was significantly associated with a higher risk of slow growth trajectory in girls (ORs with 95% CI for the entire, second trimester, and third trimester of pregnancy, respectively: 1.010 [1.001,1.018], 1.006 [1.001,1.011], 1.007 [1.002,1.012]). Prenatal PM2.5 and its composition exposure was positively associated with BMI peak in boys (ßs with 95% CI for PM2.5, SO42-, NO3-, NH4+, OM, BC: 0.004[0.000,0.007], 0.025[0.006,0.044], 0.012[0.002,0.023], 0.022[0.004,0.039], 0.016[0.001,0.031], 0.082[0.005,0.159]), and not statistically significant in girls. We observed a more pronounced BC effect in our cohort. Prenatal exposure to PM2.5 and its component, especially at 10-22 weeks of gestation, is associated with a higher risk of rapid growth in boys and a risk of slow growth in girls.

Cell Type-Specific Modulation of Acute Itch Processing in the Anterior Cingulate Cortex.

Despite remarkable progress in understanding the fundamental bases of itching, its cortical mechanisms remain poorly understood. Herein, the causal contributions of defined anterior cingulate cortex (ACC) neuronal populations to acute itch modulation in mice are established. Using cell type-specific manipulations, the opposing functions of ACC glutamatergic and GABAergic neurons in regulating acute itching are demonstrated. Photometry studies indicated that ACC glutamatergic neurons are activated during scratching induced by both histamine and chloroquine, whereas the activation pattern of GABAergic neurons is complicated by GABAergic subpopulations and acute itch modalities. By combining cell type- and projection-specific techniques, a thalamocortical circuit is further identified from the mediodorsal thalamus driving the itch-scratching cycle related to histaminergic and non-histaminergic itching, which is contingent on the activation of postsynaptic parvalbumin-expressing neurons in the ACC. These findings reveal a cellular and circuit signature of ACC neurons orchestrating behavioral responses to itching and may provide insights into therapies for itch-related diseases.

Soybean oil induces neuroinflammatory response through brain-gut axis under high-fat diet.

Neuroinflammation is considered the principal pathogenic mechanism underlying neurodegenerative diseases, and the incidence of brain disorders is closely linked to dietary fat consumption and intestinal health. To investigate this relationship, 60 8-week-old C57BL/6J mice were subjected to a 20-week dietary intervention, wherein they were fed lard and soybean oil, each at 15% and 35% fat energy. At a dietary fat energy level of 35%, inflammation was observed in both the soybean oil and lard groups. Nevertheless, inflammation was more pronounced in the mice that were administered soybean oil. The process by which nerve cell structure is compromised, inflammatory factors are upregulated, brain antioxidant capacity is diminished, and the TLR4/MyD88/NF-κB p65 inflammatory pathway is activated resulting in damage to the brain-gut barrier. This, in turn, leads to a reduction in the abundance of Akkermansia and unclassified_f_Lachnospiraceae, as well as an increase in Dubosiella abundance, ultimately resulting in brain inflammation and damage. These results suggested that soybean oil induces more severe neuroinflammation compared to lard. Our study demonstrated that, at a dietary fat energy level of 35%, compared to soybean oil, lard could be the healthier option, the outcomes would help provide a reference basis for the selection of residents' daily dietary oil.

A Review on the Interaction of Acetic Acid Bacteria and Microbes in Food Fermentation: A Microbial Ecology Perspective.

In fermented foods, acetic acid bacteria (AAB), kinds of bacteria with a long history of utilization, contribute to safety, nutritional, and sensory properties primarily through acetic acid fermentation. AAB are commonly found in various fermented foods such as vinegar, sour beer, fermented cocoa and coffee beans, kefir beverages, kombucha, and sourdough. They interact and cooperate with a variety of microorganisms, resulting in the formation of diverse metabolites and the production of fermented foods with distinct flavors. Understanding the interactions between AAB and other microbes is crucial for effectively controlling and utilizing AAB in fermentation processes. However, these microbial interactions are influenced by factors such as strain type, nutritional conditions, ecological niches, and fermentation duration. In this review, we examine the relationships and research methodologies of microbial interactions and interaction studies between AAB and yeasts, lactic acid bacteria (LAB), and bacilli in different food fermentation processes involving these microorganisms. The objective of this review is to identify key interaction models involving AAB and other microorganisms. The insights gained will provide scientific guidance for the effective utilization of AAB as functional microorganisms in food fermentation processes.

Seasonal environmental factors drive microbial community succession and flavor quality during acetic acid fermentation of Zhenjiang aromatic vinegar.

This study investigated the impact of seasonal environmental factors on microorganisms and flavor compounds during acetic acid fermentation (AAF) of Zhenjiang aromatic vinegar (ZAV). Environmental factors were monitored throughout the fermentation process, which spanned multiple seasons. Methods such as headspace solid phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS), high performance liquid chromatography (HPLC), and high-throughput sequencing were employed to examine how these environmental factors influenced the flavor profile and microbial community of ZAV. The findings suggested that ZAV brewed in autumn had the strongest flavor and sweetness. The key microorganisms responsible for the flavor of ZAV included Lactobacillus acetotolerans, Lactobacillus plantarum, Lactobacillus reuteri, Lactobacillus fermentum, Acetobacter pasteurianus. Moreover, correlation analysis showed that room temperature had a significant impact on the composition of the microbial community, along with other key seasonal environmental factors like total acid, pH, reducing sugar, and humidity. These results provide a theoretical foundation for regulating core microorganisms and environmental factors during fermentation, enhancing ZAV quality.

Enhancing the Appeal of Clinical Diagnostics Education for Medical Undergraduates Through the Innovative Incorporation of Cultural and Historical Elements Alongside the Inclusion of the COVID-19 Pandemic and Its Innovative Solutions.

Clinical diagnostics is a fundamental course required for clinical medical students and serves as a prerequisite for several advanced clinical subjects. However, recent observations indicate a decline in interest among eight-year clinical medicine students at Peking Union Medical College regarding clinical diagnostics courses. Instead, these students seem to prioritize the publication of high-impact articles and involvement in scientific research over their medical coursework, leading to a lack of sufficient attention to clinical diagnostics. In the clinical diagnostics course conducted in the first half of 2024, our objective was to engage medical students by presenting the subject matter in an interesting and relevant manner. We curated textual information regarding the health condition of Lin Daiyu, the protagonist from the Chinese literary classic "The Dream of the Red Chamber," and encouraged students to deduce potential diseases she may have experienced based on the original text. Additionally, we sourced historical photographs of Empress Dowager Cixi from the Qing Dynasty, which facilitated the hypothesis that she likely suffered from goiter. These images were employed as a practical examination question during the mid-semester assessment to evaluate the students' proficiency in conducting neck physical examinations. Furthermore, we shared an inspiring anecdote about healthcare professionals who repurposed potato chip packaging into stethoscopes during the COVID-19 pandemic, underscoring the critical role of physical diagnosis and examination in urgent situations. Following the mid-term exam in clinical diagnosis, a questionnaire survey was administered to the medical students who participated in the examination. The results indicated that 93% of the students found the question regarding Lin Daiyu to be highly engaging, while 89% found the question about Empress Dowager Cixi equally captivating. These innovative teaching strategies significantly enhanced the medical students' enthusiasm for learning clinical diagnostics.

Identification of hub genes and key pathways in arsenic-treated rice (Oryza sativa L.) based on 9 topological analysis methods of CytoHubba.

BACKGROUND: Arsenic is a toxic metalloid that can cause acute and chronic adverse health problems. Unfortunately, rice, the primary staple food for more than half of the world's population, is generally regarded as a typical arsenic-accumulating crop plant. Evidence indicates that arsenic stress can influence the growth and development of the rice plant, and lead to high concentrations of arsenic in rice grain. But the underlying mechanisms remain unclear. METHODS: In the present research, the possible molecules and pathways involved in rice roots in response to arsenic stress were explored using bioinformatics methods. Datasets that involving arsenic-treated rice root and the "study type" that was restricted to "Expression profiling by array" were selected and downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) between the arsenic-treated group and the control group were obtained using the online web tool GEO2R. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to investigate the functions of DEGs. The protein-protein interactions (PPI) network and the molecular complex detection algorithm (MCODE) of DEGs were analyzed using STRING and Cystoscope, respectively. Important nodes and hub genes in the PPI network were predicted and explored using the Cytoscape-cytoHubba plug-in. RESULTS: Two datasets, GSE25206 and GSE71492, were downloaded from Gene Expression Omnibus (GEO) database. Eighty common DEGs from the two datasets, including sixty-three up-regulated and seventeen down-regulated genes, were then selected. After functional enrichment analysis, these common DEGs were enriched mainly in 10 GO items, including glutathione transferase activity, glutathione metabolic process, toxin catabolic process, and 7 KEGG pathways related to metabolism. After PPI network and MCODE analysis, 49 nodes from the DEGs PPI network were identified, filtering two significant modules. Next, the Cytoscape-cytoHubba plug-in was used to predict important nodes and hub genes. Finally, five genes [Os01g0644000, PRDX6 (Os07g0638400), PRX112 (Os07g0677300), ENO1(Os06g0136600), LOGL9 (Os09g0547500)] were verified and could serve as the best candidates associated with rice root in response to arsenic stress. CONCLUSIONS: In summary, we elucidated the potential pathways and genes in rice root in response to arsenic stress through a comprehensive bioinformatics analysis.

Multiomics-Based Biocargo Components Analysis in Enterococcus faecium Membrane Vesicles.

Enterococcus spp. have been shown to have gastrointestinal tract protective functions; our recent results suggest that membrane vesicles (MVs) play an important role in the gastric protection of Enterococcus faecium (E. faecium). The specific function is determined by molecular compositions of MVs. To resolve biocargo components in E. faecium MVs (EfmMVs), MVs were isolated from E. faecium culture. Transcriptomics, label-free quantitative proteomics, and untargeted metabolomics were performed to obtain information about the complexity of ribonucleic acids (RNAs), proteins, and metabolites biocargo they carry, respectively. RNA-sequencing identified a total of 2122 transcripts. The top 20 transcripts accounted for 27.63% of total counts, which, including enzymes, participate in glycolysis, ribosomal proteins, DNA-directed RNA polymerases, protein-synthesizing relative enzymes, molecules associated with protein post-translational processing and transport, and peptidoglycan lyases. Label-free quantitative proteomics analysis identified a total of 711 proteins. The top 20 proteins accounted for 48.02% of all identified proteins, which including ribosomal proteins, enzymes participate in glycolysis, DNA-directed RNA polymerases, protein-synthesizing relative enzymes, peptidoglycan lyases, and autolysin. Untargeted metabolomics analysis identified a total of 519 metabolites. The top 20 metabolites accounted for 79.55% of all identified metabolites, which included amino acids, substrates, or products in the metabolism of amino acids, natural organic acids, products in the metabolism of organic acids, ketone compounds, and two other compounds. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses indicated that the identified biocargo components enriched in metabolism, genetic, and environmental information processing. Overall, we hope that the current exploration of multiple "-omics" analyses of this EfmMVs will provide useful information and further groundwork for future studies on E. faecium application.

African Swine Fever Virus Immunosuppression and Virulence-Related Gene.

African swine fever virus (ASFV), a highly contagious pathogen characterized by a complex structure and a variety of immunosuppression proteins, causes hemorrhagic, acute, and aggressive infectious disease that severely injures the pork products and industry. However, there is no effective vaccine or treatment. The main reasons are not only the complex mechanisms that lead to immunosuppression but also the unknown functions of various proteins. This review summarizes the interaction between ASFV and the host immune system, along with the involvement of virulence-related genes and proteins, as well as the corresponding molecular mechanism of immunosuppression of ASFV, encompassing pathways such as cGAS-STING, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), Janus Kinase (JAK) and JAK Signal Transducers and Activators of Transcription (STAT), apoptosis, and other modulation. The aim is to summarize the dynamic process during ASFV infection and entry into the host cell, provide a rational insight into development of a vaccine, and provide a better clear knowledge of how ASFV impacts the host.

Comparison analysis of the burden and attributable risk factors of early-onset and late-onset colorectal cancer in China from 1990 to 2019.

OBJECTIVES: The project intended to analyze the impact of burden and related risk factors of late-onset colorectal cancer (LOCRC) and early-onset colorectal cancer (EOCRC) in China, thus offering essential references for optimizing prevention and control strategies. METHOD: Global Burden of Disease Study was employed to describe burden changes of EOCRC and LOCRC in China during 1990-2019, containing the numbers of incidence, deaths, prevalence, and disability-adjusted life years (DALYs), and to compare attributable deaths and DALYs risk factors in varying age and sex segments. RESULTS: The numbers and corresponding crude rates of incidence, deaths, prevalence, and DALYs of EOCRC and LOCRC in China during 1990-2019 demonstrated an upward trend across all age categories, with males being dramatically predominant. Overall, over time, the impact of a low-calcium diet and a low-fiber diet on mortality and DALY rates decreased, while the impact of other risk factors increased. In terms of gender, the risk factors affecting males changed greatly, with smoking, inadequate milk intake, and the low whole-grain diet being the main factors in 2019, while in 1990, the main factors were the low-calcium diet, smoking, and inadequate milk intake. CONCLUSION: The burden of colorectal cancer in China is concerning. Patients grouped by diagnostic age exhibit different characteristics, indicating the need for high-quality research in the future to achieve personalized medicine tailored to different population characteristics.

Fabrication of PHFPO Surface-Modified Conductive AgNWs/PNAGA Hydrogels with Enhanced Water Retention Capacity toward Highly Sensitive Strain Sensors.

Conductive hydrogels, characterized by their unique features of flexibility, biocompatibility, electrical conductivity, and responsiveness to environmental stimuli, have emerged as promising materials for sensitive strain sensors. In this study, a facile strategy to prepare highly conductive hydrogels is reported. Through rational structural and synthetic design, silver nanowires (AgNWs) are incorporated into poly(N-acryloyl glycinamide) (PNAGA) hydrogels, achieving high electrical conductivity (up to 0.88 S m-1), significantly enhanced mechanical properties, and elevated deformative sensitivity. Furthermore, surface modification with polyhexafluoropropylene oxide (PHFPO) has substantially improved the water retention capacity and dressing comfort of this hydrogel material. Based on the above merits, these hydrogels are employed to fabricate highly sensitive wearable strain sensors which can detect and interpret subtle hand and finger movements and enable precise control of machine interfaces. The AgNWs/PNAGA based strain sensors can effectively sense finger motion, enabling the control of robotic fingers to replicate the human hand's gestures. In addition, the high deformative sensitivity and elevated water retention performance of the hydrogels makes them suitable for flow sensing. These conceptual applications demonstrate the potential of this conductive hydrogel in high-performance strain sensors in the future.

Colonoscopic removal of an intrauterine device with rectal perforation: A case report.

RATIONALE: The intrauterine device is one of the effective, safe, convenient, economical, and reversible contraceptive methods. Although its contraceptive effect is definite, some female patients may experience complications such as expulsion, bleeding, and pregnancy with the device in place. Rectal perforation is one of the rare and serious complications, which can lead to complications such as abdominal infection and intestinal adhesions, severely affecting the quality of life of patients. PATIENT CONCERNS: A 34-year-old female was sent to the Department of Gastroenterology with noticeable left lower quadrant abdominal pain. She had presented with abdominal discomfort and anal tenesmus 1 year earlier. Two months ago, her abdominal pain had gradually worsened and she was presented to our hospital. DIAGNOSES: Investigations, including colonoscopy and computed tomography scan, had revealed an intrauterine device migrated and perforated into the rectum. INTERVENTIONS AND OUTCOMES: The patient underwent successful colonoscopic removal of the intrauterine device. She recovered well after the treatment. LESSONS: This case proves that endoscopic therapy can be considered the preferred method for removing intrauterine devices displaced into the digestive tract lumen.

Electrochemical Behaviors and Doping Rules of NaRhO2 Cathode Materials for Sodium-Ion Batteries.

Sodium-ion batteries (SIBs) have great advantages for energy storage and conversion due to their low cost and large storage capacity. Currently, NaRhO2 is used as an electrode material for sodium-ion batteries. Doping first- and second-row transition metals has been carried out to comprehensively assess NaRhO2 as a cathode material. The geometric and electronic structures and electrochemical and doping behaviors of NaRhO2 cathode materials for SIBs have been investigated using density functional theory calculations. The results show that the bond lengths of Rh-O in NaRhO2 decrease during sodium deintercalation. The band gap of NaRhO2 with sodium extraction gradually reduces. The density of states of NaxRhO2 shows that the interaction between the Rh-4d and O-2p orbitals increases and the orbitals shift toward the right. The average intercalation voltage of NaxRhO2 cathode material increased from 2.7 to 3.9 eV. After doping with first- and second-row transition metal elements from Sc to Zn and Y to Cd, the changes in the band gaps of the doped NaRhO2 materials exhibit a W-type rule. In contrast, their magnetic moments show a reverse W-type rule. These findings on the pristine and doped NaRhO2 can provide theoretical guidance for the preparation of novel electrode materials suitable for sodium-ion batteries.
