An atoxigenic Aspergillus flavus PA67 from Shandong province exhibits potential in biocontrol against toxigenic Aspergillus flavus, Sclerotium rolfsii, and Fusarium proliferatum.

Peanuts and corn are susceptible to various soil-borne fungi, leading to significant economic losses. Atoxigenic Aspergillus flavus have been widely used as biocontrol agents for managing aflatoxin contamination because of their minimal environmental impact, strong competitive ability, and sustained inhibition effect. After multiple identifications and cluster amplification pattern (CAP) analysis, three atoxigenic A. flavus PA04, PA10 and PA67 were isolated from peanut samples in Shandong Province, which can reduce aflatoxin levels by up to 90 %. Our study revealed that atoxigenic A. flavus also competed vigorously with Sclerotium rolfsii and Fusarium proliferatum for nutrition and space, achieving notable inhibition rates of up to 90.4 % and 90.6 %, respectively. The supernatants of atoxigenic A. flavus also inhibited the growth of S. rolfsii and F. proliferatum, with PA67 demonstrating the most significant effect. Whole genome sequencing revealed that PA67 contains multiple glycoside hydrolases and metabolites with antifungal activity. The kojic acid production of PA67 was higher than that of PA04 and PA10, reaching 17.48 g/L, which has a significant inhibition on sclerotia germination. PA67 supernatant significantly inhibited the hyphae growth of S. rolfsii and F. proliferatum, and down-regulated genes related to sclerotia and fumonisin formation. This study demonstrates the biocontrol potential of PA67 against three soil-borne fungi and is the first investigation of atoxigenic A. flavus to inhibit S. rolfsii and F. proliferatum.

Development of a cost-effective confocal Raman microscopy with high sensitivity.

Confocal Raman microscopy is a powerful technique for identifying materials and molecular species; however, the signal from Raman scattering is extremely weak. Typically, handheld Raman instruments are cost-effective but less sensitive, while high-end scientific-grade Raman instruments are highly sensitive but extremely expensive. This limits the widespread use of Raman technique in our daily life. To bridge this gap, we explored and developed a cost-effective yet highly sensitive confocal Raman microscopy system. The key components of the system include an excitation laser based on readily available laser diode, a lens-grating-lens type spectrometer with high throughput and image quality, and a sensitive detector based on a linear charge-coupled device (CCD) that can be cooled down to -30 °C. The developed compact Raman instrument can provide high-quality Raman spectra with good spectral resolution. The 3rd order 1450 cm-1 peak of Si (111) wafer shows a signal-to-noise ratio (SNR) better than 10:1, demonstrating high sensitivity comparable to high-end scientific-grade Raman instruments. We also tested a wide range of different samples (organic molecules, minerals and polymers) to demonstrate its universal application capability.

Encapsulating CoNi nanoparticles into nitrogen-doped carbon nanotube arrays as bifunctional oxygen electrocatalyst for rechargeable zinc-air batteries.

The high theoretical specific energy and environmental friendliness of zinc-air batteries (ZABs) have garnered significant attention. However, the practical application of ZABs requires overcoming the sluggish kinetics associated with oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, 3D self-supported nitrogen-doped carbon nanotubes (N-CNTs) arrays encapsulated by CoNi nanoparticles on carbon fiber cloth (CoNi@N-CNTs/CFC) are synthesized as bifunctional catalysts for OER and ORR. The 3D interconnected N-CNTs arrays not only improve the electrical conductivity, the permeation and gas escape capabilities of the electrode, but also enhance the corrosion resistance of CoNi metals. DFT calculations reveal that the co-existence of Co and Ni synergistically reduces the energy barrier for OOH conversion to OH, thereby optimizing the Gibbs free energy of the catalysts. Additionally, analysis of the change in energy barrier during the rate-determining step suggests that the primary catalytic active center is Ni site for OER. As a result, CoNi@N-CNTs/CFC exhibits superior catalytic activity with an overpotential of 240 mV at 10 mA cm-2 toward OER, and the onset potential of 0.92 V for ORR. Moreover, utilization of CoNi@N-CNTs/CFC in liquid and solid-state ZABs exhibited exceptional stability, manifesting a consistent cycling operation lasting for 100 and 15 h, respectively.

Epidemiologic trends and survival outcomes in patients with primary digestive system lymphoma in the United States.

BACKGROUND AND AIMS: Primary digestive system lymphoma (PDSL) is an important entity of extranodal lymphoma, yet updated epidemiologic and survival data are lacking. METHODS: Patients diagnosed with PDSL between 1975 and 2020 were identified from the Surveillance, Epidemiology, and End Results database. Kaplan-Meier analysis estimated survival outcomes. Multivariable Cox regression identified independent risk factors, and nomograms were developed to predict 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS). RESULTS: A total of 30,568 patients with PDSL were identified, with 57.9% being male and 80.4% white. The most frequent tumor site was the stomach (48.7%) and diffuse large B-cell lymphoma (DLBCL) was the predominant histologic subtype (45.0%). The overall incidence from 2016 to 2020 was 11.11 per 1,000,000 persons, with a decrease observed in lymphoma rates for the stomach, small intestine, large intestine, and pancreas. Long-term trends showed an initial rise in PDSL incidence, followed by a decline since the 1990s. The median OS across all patients was 103 months, with appendiceal lymphoma showing the highest median OS of 253 months. Factors including diagnosis year, age, sex, race, primary tumor site, histologic subtype, stage, and treatment modalities were significantly associated with OS and CSS. Nomograms achieved C-indices of 0.720 for OS and 0.723 for CSS in the training cohort. CONCLUSION: The incidence of PDSL initially increased but has recently declined. Survival for all PDSL patients has improved over time. Nomograms to predict survival for patients with DLBCL exhibited good predictive and discriminating abilities.

Immunometabolism: signaling pathways, homeostasis, and therapeutic targets.

Immunometabolism plays a central role in sustaining immune system functionality and preserving physiological homeostasis within the organism. During the differentiation and activation, immune cells undergo metabolic reprogramming mediated by complex signaling pathways. Immune cells maintain homeostasis and are influenced by metabolic microenvironmental cues. A series of immunometabolic enzymes modulate immune cell function by metabolizing nutrients and accumulating metabolic products. These enzymes reverse immune cells' differentiation, disrupt intracellular signaling pathways, and regulate immune responses, thereby influencing disease progression. The huge population of immune metabolic enzymes, the ubiquity, and the complexity of metabolic regulation have kept the immune metabolic mechanisms related to many diseases from being discovered, and what has been revealed so far is only the tip of the iceberg. This review comprehensively summarized the immune metabolic enzymes' role in multiple immune cells such as T cells, macrophages, natural killer cells, and dendritic cells. By classifying and dissecting the immunometabolism mechanisms and the implications in diseases, summarizing and analyzing advancements in research and clinical applications of the inhibitors targeting these enzymes, this review is intended to provide a new perspective concerning immune metabolic enzymes for understanding the immune system, and offer novel insight into future therapeutic interventions.

Mitotic Arrest Deficient 2 Like 1 Contributes to Colorectal Cancer Cell Migration, Invasion, and Oxaliplatin Resistance Through the Wnt/ß-Catenin Pathway.

Colorectal cancer (CRC) is a highly prevalent malignancy, requiring chemotherapy for advanced stages of the disease. Previously, we found that mitotic arrest deficient 2 like 1 (MAD2L1) was upregulated and facilitated malignant proliferation in CRC. However, the association between MAD2L1 expression and tumor progression, as well as chemotherapy resistance in CRC, remains unclear. The progression capacities of CRC cells were assessed using transwell and wound healing assays, and the resistance to cisplatin in oxaliplatin-resistant CRC cells was assessed using CCK-8 assay and flow cytometry. Relevant protein levels of epithelial-to-mesenchymal transition (EMT) and Wnt/ß-catenin pathway were analyzed using western blotting. Revealing the impact of MAD2L1 on metastasis and drug resistance in CRC through inhibition of the Wnt/ß-catenin pathway. Knockdown of MAD2L1 attenuated the malignant progression of CRC cells, inhibited EMT, and blocked the Wnt/ß-catenin pathway. MAD2L1 was significantly upregulated in oxaliplatin-resistant CRC cells, accompanied by the activation of the Wnt/ß-catenin pathway. Knockdown of MAD2L1 effectively reversed oxaliplatin resistance, leading to apoptosis and downregulation of the protein expression levels of ß-catenin, P-glycoprotein (P-gp), and ABCG2. After the knockdown of MAD2L1, the inhibition of the Wnt/ß-catenin pathway exhibited a synergistic effect, effectively suppressing malignant progression and reversing oxaliplatin resistance in CRC cells. So, knockdown of MAD2L1 suppressed cell malignant progression, equally sensitized resistant CRC cells to oxaliplatin, potentially by blocking the activation of the Wnt/ß-catenin pathway.

Experiences of caregivers of patients with traumatic brain injury during hospitalization in western China: A qualitative study.

Family members frequently provide both physical and emotional support to patients. Previous studies have focused primarily on the experiences of patients with traumatic brain injury (TBI) and their caregivers during home care and the transition from hospital care to the community, with less emphasis on their experiences during acute hospital care immediately after TBI. This study aimed to explore the experiences of caregivers of patients with TBI during acute hospitalizations. A qualitative descriptive study using individual semistructured interviews was conducted at the trauma center of a tertiary hospital in western China. A purposive sample of 21 caregivers of patients with TBI were recruited. The interviews were conducted face to face in the inpatient ward from July to September 2023. Conventional content analysis was used to conduct the framework analysis. The experiences of caregivers were identified within three key themes: TBI consequences in patients (physical impairments, psychological distress, and cognitive dysfunctions), challenges of caregivers (physiological/emotional/economic burdens, conflicts, and concerns regarding recovery), and needs of caregivers (health information, medical services, and recovery expectations). This study highlights the experiences of caregivers of patients with TBI during hospital stays in western China. The challenges faced by caregivers and the needs of caregivers are multidimensional. Appropriate support should be provided to alleviate the burden of caregiving.

The Effect of Urinary Polycyclic Aromatic Hydrocarbon Metabolites on Lipid Profiles: Does Oxidative Stress Play a Crucial Mediation Role?

Urinary polycyclic aromatic hydrocarbon (PAH) metabolites are associated with oxidative stress; however, epidemiological studies have not reported the impacts of these urinary PAH metabolites on blood lipid levels. This study investigated the relationship between urinary PAH metabolites, urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), and blood lipid profiles. A total of 109 elderly volunteers were recruited with complete datasets for analysis. Blood and morning urine samples were collected in the winter of 2011. The PAH metabolites, creatinine, and 8-OHdG levels in urine samples were analyzed using Gas Chromatography-Mass Spectrometry, spectrophotometry, and an ELISA kit, respectively. The blood lipid profiles were analyzed using an automatic biochemical analyzer. The relationship between lipid profiles and 8-OHdG was assessed using a two-independent sample nonparametric test, categorized by gender, smoking, and alcohol consumption status. After normalizing the concentration values, a general linear regression model was employed to examine the correlations between PAH metabolites, 8-OHdG, and lipid profiles. A mediation model was developed to investigate the mediating effect of 8-OHdG on the relationship between PAH metabolites and lipid profiles. The median of eight PAH metabolite concentrations in urine samples ranged from 1 to 10 µmol/mol creatinine (Cr). Significant differences in lipid profiles were observed across genders. However, no significant differences were found in smoking or alcohol consumption status for both genders. Linear regression analysis revealed that an increase in the logarithmic concentration of 2-hydroxynaphthalene (2-OHNap), 9-hydroxyfluorene (9-OHFlu), 3-hydroxyfluorene (3-OHFlu), 2-hydroxyfluorene (2-OHFlu), 1-hydroxypyrene (1-OHPyr), and 6-hydroxychrysene (6-OHChr) was associated with an increase in urinary 8-OHdG levels, after adjusting for BMI and age. Specifically, 1-hydroxynaphthalene (1-OHNap) and 1-OHPyr correlated negatively with apolipoprotein A1 (Apo A1). Conversely, 1-OHPyr was positively correlated with low-density lipoprotein cholesterol (LDL-C). In addition, b,c-dihydroxyphenanthrene (2-OHBcPhe) was positively associated with apolipoprotein B (Apo B). Notably, 8-OHdG did not exhibit a significant correlation with lipid profiles. The mediating effect of 8-OHdG on the relationship between hydroxylated PAHs and lipid profiles was not statistically significant. However, the indirect effects of hydroxylated PAHs on blood lipids were statistically substantial, specifically for 1-OHNap to Apo A1 (-0.025, 95% CI: -0.041, -0.009), 1-OHPyr to LDL-C (0.107, 95% CI: 0.011, 0.203), and 2-OHBcPhe to Apo B (0.070, 95% CI: 0.005, 0.135). This study suggests that an increase in urinary PAH metabolites may elevate the levels of urinary 8-OHdG and influence blood lipid profiles. However, no direct relationship was found between 8-OHdG and lipid profiles. The mediation analysis indicated that the effects of PAH metabolites on lipid changes may operate through pathways other than oxidative stress.

Rapid discrimination and quantification of chemotypes in Perillae folium using FT-NIR spectroscopy and GC-MS combined with chemometrics.

Perillae Folium (PF) is a well-known food and herb containing different chemotypes, which affect its quality. Herein, a method was proposed to classify and quantify PF chemotypes using gas chromatography-mass spectrometry (GC-MS) and Fourier transform-near infrared spectroscopy (FT-NIR). GC-MS results revealed that PF contains several chemotypes, including perilla ketone (PK) type, α-asarone (PP-as) type, and dillapiole (PP-dm) type, with the PK type being the predominant chemotype. Based on FT-NIR data, different chemotypes were accurately classified. The random forest algorithm achieved >90 % accuracy in chemotype classification. Furthermore, the main components of perilla ketone and isoegomaketone in PF were successfully quantified using partial least squares regression models, with prediction to deviation values of 3.76 and 2.59, respectively. This method provides valuable insights and references for the quality supervision of PF and other foods.

LncRNA LINC01503 promotes angiogenesis in colorectal cancer by regulating VEGFA expression via miR-342-3p and HSP60 binding.

Colorectal cancer (CRC) ranks among the top five most common malignant tumors worldwide and has a high mortality rate. Angiogenesis plays an important role in CRC progression; however, anti-angiogenesis therapy still has many limitations. Long non-coding RNAs (lncRNAs) participate in tumor progression by regulating vascular endothelial growth factor expression in metastatic CRC. Thus, targeting specific lncRNA may provide some new hope for anti-angiogenic strategies. Through analyzing data both from both clinical samples and The Cancer Genome Atlas database, we found that the lncRNA LINC01503 was specifically upregulated in CRC tissues, and was associated with tumor progression and a poor overall survival. We also demonstrated that LINC01503 enhanced the capacity of tube formation and migration of vascular endothelial cells, thus promoting CRC tumorigenesis by upregulating vascular endothelial growth factor A (VEGFA) expression in CRC cells. Mechanistically, LINC01503 promoted the expression of VEGFA by simultaneously regulating the stability of both the mRNA and VEGFA by binding to miR-342-3p and the chaperone HSP60. The upregulation of LINC01503 in CRC cells was attributed to the CREB-binding protein CBP/p300-mediated H3K27 acetylation of the LINC01503 promoter region. Taken together, our findings clarify the mechanism by which LINC01503 may promote CRC angiogenesis, implicating that LINC01503 may serve as a potential prognostic biomarker and therapeutic target for CRC.

An unbiased, sustainable, evidence-informed Universal Food Guide: a timely template for national food guides.

BACKGROUND: Although national food guides are designed, ostensibly, to translate scientific evidence with respect to food, dietary patterns, and health, their development has increasingly become a corporate/political process as well as scientific one; often with corporate/political influences overriding science. Our aim was to construct an unbiased, sustainable, evidence-informed Universal Food Guide to serve as a template for countries to develop their unique guides, thereby, provide a valid resource for health professionals, health authorities, and the public. METHODS: To address our aim, we conducted an integrative review of multiple evidence-informed sources (e.g., established databases, evidence syntheses, scholarly treatises, and policy documents) related to four areas: 1. Food guides' utility and conflicts of interest; 2. The evidence-based healthiest diet; 3. Constituents of the Universal Food Guide template; and 4. Implications for population health; regulation/governance; environment/climate/planetary health; and ethics. RESULTS: The eating pattern that is healthiest for humans (i.e., most natural, and associated with maximal health across the life cycle; reduced non-communicable disease (NCD) risk; and minimal end-of-life illness) is whole food, low fat, plant-based, especially vegan, with the absence of ultra-processed food. Disparities in national food guide recommendations can be explained by factors other than science, specifically, corporate/political interests reflected in heavily government-subsidized, animal-sourced products; and trends toward dominance of daily consumption of processed/ultra-processed foods. Both trends have well-documented adverse consequences, i.e., NCDs and endangered environmental/planetary health. Commitment to an evidence-informed plant-based eating pattern, particularly vegan, will reduce risks/manifestations of NCDs; inform healthy food and nutrition policy regulation/governance; support sustainable environment/climate and planetary health; and is ethical with respect to 'best' evidence-based practice, and human and animal welfare. CONCLUSION: The Universal Food Guide that serves as a template for national food guides is both urgent and timely given the well-documented health-harming influences that corporate stakeholders/politicians and advisory committees with conflicts of interest, exert on national food guides. Such influence contributes to the largely-preventable NCDs and environmental issues. Policy makers, health professionals, and the public need unbiased, scientific evidence as informed by the Universal Food Guide, to inform their recommendations and choices.

ß-glucan regulates the intestinal immunity of pearl gentian grouper via the nuclear factor kappa B signaling pathway.

The preceding study observed that yeast ß-glucan supplementation enhanced intestinal health and augmented disease resistance in pearl gentian grouper (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀), which occurred concurrently with the activation of the nuclear factor kappa B (NFκB) signaling pathway. Thus, we hypothesized that ß-glucan improves intestinal health in grouper by modulating the NFκB pathway. Accordingly, the present study examined the effects of NFκB pathway disruption using a specific inhibitor on the intestinal health of pearl gentian grouper that had been injected with ß-glucan. The experimental groups were as follows, (1) CD group: PBS injected; (2) ßG group: ß-glucan injected at a dose of 80 mg/kg; (3) PDTC group: NFκB inhibitor PDTC injected at a dose of 30 mg/kg; (4) ßG + PDTC group: a combination of ß-glucan (80 mg/kg) and PDTC (30 mg/kg) injected together. The results demonstrated that ß-glucan-induced increases in mRNA expression levels of NFκB inhibitor α (iκbα) and p65, the degradation and phosphorylation of IκBα, and the phosphorylation of NFκB p65 were significantly inhibited following NFκB inhibition using PDTC in the intestine of grouper. The PDTC injection resulted in a significant reduction in the ß-glucan-induced increase in mucin levels. The ß-glucan-induced elevation of alkaline phosphatase (AKP) activity, component 3 (C3) content, and inflammatory factors were significantly suppressed following NFκB inhibition. The ßG + PDTC treatment resulted in a restoration of catalase (CAT) enzyme activity to the level observed in the CD treatment, while total antioxidant capacity (T-AOC) was decreased to the level of the ßG treatment. The ß-glucan-induced downregulation of caspase8 (casp8) was reversed following NFκB inhibition, as well as the mRNA levels of casp3 and casp9 being elevated to a greater extent. In conclusion, the ß-glucan-regulated intestinal immunity in grouper may be mediated by the NFκB pathway. Furthermore, the inhibitory effect of ß-glucan on apoptosis and oxidative stress may not be related to the NFκB signaling pathway.

Lnc-Pim1 Promotes Neurite Outgrowth and Regeneration of Neuron-Like Cells Following ACR-Induced Neuronal Injury.

Decreased regenerative capacity of central nervous system neurons is the main cause for failure of damaged neuron regeneration and functional recovery. Long noncoding RNAs (lncRNAs) are abundant in mammalian transcriptomes, and many time- and tissue-specific lncRNAs are thought to be closely related to specific biological functions. The promoting effect of Pim-1 gene on neural differentiation and regeneration has been documented, but the effect and mechanism of its neighbor gene Lnc-Pim1 in regulating the response of central neurons to injury remain unclear. RT-PCR in this study demonstrated that the expression of Lnc-Pim1 was upregulated in acrylamide (ACR)-induced neuronal injury. FISH and nucleus-cytoplasmic assay demonstrated that Lnc-Pim1 was mainly expressed in the neuron cytoplasm, with a small amount in the nucleus. Western blot analysis proved that Lnc-Pim1 overexpression induced by the lentivirus vector could promote neurite outgrowth in Neuro-2a cells by activating the Erk1/2 signal pathway, and improve neurite regeneration of injured neurons by upregulating GAP-43 and ß-Ⅲ tubulin protein expression. However, silencing Lnc-Pim1 expression by interfering RNA could effectively downregulate the GAP-43 and ß-Ⅲ tubulin protein expression, and inhibit neurite growth of neurons. In addition, CHIRP-MS was performed to identify several potential targets of Lnc-Pim1 involved in the regulation of neurite regeneration of injured neurons. In conclusion, our study demonstrated that Lnc-Pim1 is a potential lnc-RNA, playing an important role in regulating central nerve regeneration.

Genomic characteristics of antimicrobial resistance and virulence factors of carbapenem-resistant Stutzerimonas nitrititolerans isolated from the clinical specimen.

BACKGROUND: Stutzerimonas nitrititolerans (S. nitrititolerans) is a rare human pathogenic bacterium and has been inadequately explored at the genomic level. Here, we report the first case of carbapenem-resistant S. nitrititolerans isolated from the peritoneal dialysis fluid of a patient with chronic renal failure. This study analyzed the genomic features, antimicrobial resistance, and virulence factors of the isolated strain through whole genome sequencing (WGS). METHODS: The bacterial isolate from the peritoneal dialysis fluid was named PDI170223, and preliminary identification was conducted through Matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF MS). WGS of the strain PDI170223 was performed using the Illumina platform, and a phylogenetic tree was constructed based on the 16S rRNA gene sequences. Antimicrobial susceptibility test (AST) was conducted using the TDR-200B2 automatic bacteria identification/drug sensitivity tester. RESULTS: S. nitrititolerans may emerge as a human pathogen due to its numerous virulence genes, including those encoding toxins, and those involved in flagellum and biofilm formation. The AST results revealed that the strain is multidrug- and carbapenem-resistant. The antimicrobial resistance genes of S. nitrititolerans are complex and diverse, including efflux pump genes and ß⁃lactam resistance genes. CONCLUSION: The analysis of virulence factors and antimicrobial resistance of S. nitrititolerans provides clinical insight into the pathogenicity and potential risks of this bacterium. It is crucial to explore the mechanisms through which S. nitrititolerans causes diseases and maintains its antimicrobial resistance, thereby contributing to development of effective treatment and prevention strategies.

The mediating effect of social connectedness between internet gaming disorder and somatic symptoms in adolescents: a large sample cross-sectional study.

BACKGROUND: Previous studies have indicated that social connectedness can serve as a protective buffer against negative outcomes associated with online victimization. However, the role of social connectedness between Internet gaming disorder and somatic symptoms is still unclear. This study aims to examine the mediating effect of social connectedness on the association between Internet gaming disorder and somatic symptoms. METHODS: A cross-sectional design was utilized, using questionnaires for data collection and multi-stage stratified cluster sampling. The general demographic questionnaire, Nine-Item Internet Gaming Disorder Scale-Short Form, Social Connectedness Scale-Revised and Patient Health Questionnaire Physical Symptoms were used to collect data. We adopted Pearson's correlation analysis and the PROCESS Macro Model in regression analysis to explore the relationships among Internet gaming disorder, social connectedness and somatic symptoms. RESULTS: Internet gaming disorder was positively correlated with somatic symptoms (r = 0.20, P < 0.001), while network (r=-0.08, P < 0.001) and real-life social connectedness (r=-0.31, P < 0.001) negatively affected somatic symptoms. The network social connectedness and the real-life social connectedness played a chain mediating role in the development of Internet gaming disorder to somatic symptoms [95%CI: 0.073, 0.088], explaining 45.25% of the total effect value. The difference of real-life social connectedness and network social connectedness played a partial mediating role between Internet gaming disorder and somatic symptoms [95% CI:0.050, 0.062], accounting for 31.28% of the total effect value. CONCLUSIONS: Real-life social connectedness, network social connectedness, and their disparity all mediated the relationship between Internet gaming disorder and somatic symptoms. Real-life social connectedness acted as a protective factor, while network social connectedness served as a risk factor. Encouraging offline activities and guiding teenagers to use the internet responsibly may help prevent and reduce physical symptoms linked to Internet gaming disorder.

Ponte: Represent Totally Binary Neural Network Toward Efficiency.

In the quest for computational efficiency, binary neural networks (BNNs) have emerged as a promising paradigm, offering significant reductions in memory footprint and computational latency. In traditional BNN implementation, the first and last layers are typically full-precision, which causes higher logic usage in field-programmable gate array (FPGA) implementation. To solve these issues, we introduce a novel approach named Ponte (Represent Totally Binary Neural Network Toward Efficiency) that extends the binarization process to the first and last layers of BNNs. We challenge the convention by proposing a fully binary layer replacement that mitigates the computational overhead without compromising accuracy. Our method leverages a unique encoding technique, Ponte::encoding, and a channel duplication strategy, Ponte::dispatch, and Ponte::sharing, to address the non-linearity and capacity constraints posed by binary layers. Surprisingly, all of them are back-propagation-supported, which allows our work to be implemented in the last layer through extensive experimentation on benchmark datasets, including CIFAR-10 and ImageNet. We demonstrate that Ponte not only preserves the integrity of input data but also enhances the representational capacity of BNNs. The proposed architecture achieves comparable, if not superior, performance metrics while significantly reducing the computational demands, thereby marking a step forward in the practical deployment of BNNs in resource-constrained environments.

Optimizing extubation success: a comparative analysis of time series algorithms and activation functions.

Conclusion: This study proposes a prediction method using GRU on the topic of extubation, and it can provide the doctors with the clinical application of extubation to give advice for reference.

Circular RNA TAF4B targeting MFN2 accelerates cell growth in bladder cancer through p27 depression and AKT activation.

Introduction: Bladder cancer (BCa) is a common malignancy in the urinary tract. It has high recurrence rates and often requires microscopic examination, which presents significant challenges in clinical treatment. Previous research has shown that circular TAF4B (circTAF4B) is significantly upregulated in BCa and is associated with a poor prognosis. However, the specific targets and molecular mechanisms by which circTAF4B functions in BCa are still not well - understood. Methods: In this study, an RNA pull - down assay and mass spectrometry were utilized to identify MFN2 as a binding protein of circTAF4B. Additionally, siRNA was used to silence MFN2 to observe the amplification of the inhibitory effects of circTAF4B overexpression on cell growth and migration in BCa cells. Moreover, circTAF4B shRNA lentiviral particles were employed to study their impact on BCa progression by examining the regulation of p27 and the blocking of AKT signaling. Results: It was found that MFN2 is a binding protein of circTAF4B. Silencing MFN2 with siRNA enhanced the inhibitory effects of circTAF4B overexpression on cell growth and migration in BCa cells. Also, circTAF4B shRNA lentiviral particles inhibited BCa progression by upregulating p27 and blocking AKT signaling. Discussion: In conclusion, the physical binding of circTAF4B to MFN2 is a crucial process in the tumorigenesis and progression of BCa. Targeting circTAF4B or its complexes may have potential as a therapeutic strategy for BCa diagnosis and treatment.
