Characteristics of gut flora in children who go to bed early versus late.

Investigating the characteristics of the gut flora in children who go to bed early versus late. The study sample consisted of 88 healthy children aged 2-14 years, with an equal number of boys and girls. The researchers collected faecal samples from all participants and sequenced the genome of their gut flora. Findings indicate that beta diversity was statistically significant at the genus level for both the early and late sleeper groups (P = 0.045). Furthermore, alpha diversity indicators, including Simpson's index (P = 0.0011) and Shannon's index (P = 0.0013), exhibited higher values at the genus level. The differences observed in terms of species diversity, abundance, and metabolic pathways offer potential avenues for implementing pharmacological interventions aimed at addressing sleep disorders in children.

Methods: This retrospective study included 292 patients who underwent gastrointestinal endoscopy under acupuncture anesthesia at the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from June 2020 to May 2023. Logistic regression analysis was used to identify risk factors for complications in patients undergoing gastrointestinal endoscopy under acupuncture anesthesia. A nomogram prediction model was constructed using the RMS package of R4.1.2 software based on the independent risk factors identified. The predictive performance of the model was assessed using consistency index (C-index), calibration curve, and receiver operating characteristic (ROC) curve. Results: Seventy-five patients (25.68%) had complications. Body mass index (BMI), history of cardiovascular diseases, fasting time, history of respiratory diseases, and Sedation-Agitation Scale (SAS) score were identified as risk factors for complications. Based on this risk, a nomogram predictive model was constructed. The C-index of the nomogram model was 0.927. Calibration curve showed a good consistency between actual observations and nomogram predictions. The ROC curve area under curve (AUC) was 0.927 (95% CI: 0.895-0.959), indicating a certain predictive value for the occurrence of complications. When the optimal cut-off value was selected, the sensitivity and specificity of the model were 77.0% and 92.0%, respectively, indicating that the predictive model was effective. Conclusions: BMI, history of cardiovascular disease, fasting time, history of respiratory disease, and SAS score are independent risk factors for complications in patients undergoing gastrointestinal endoscopy under acupuncture anesthesia. The constructed nomogram predictive model has a good performance in predicting the occurrence of complications in patients undergoing gastrointestinal endoscopy with under acupuncture anesthesia.

Is there sufficient evidence to support the health benefits of including donkey milk in the diet?

Donkey milk has attracted attention due to its distinctive nutritional composition and potential health advantages, particularly because of its whey protein content, which includes lysozyme, α-lactalbumin, lactoferrin, and ß-lactoglobulin and vitamin C, among other components. These elements contribute to immunoregulatory, antimicrobial, antioxidant, and anti-inflammatory properties, positioning donkey milk as a possible therapeutic option. In addition, due to the low levels of caseins, the casein-to-whey protein ratio, and the ß-lactoglobulin content in donkey milk, it presents an optimal alternative for infant formula for individuals with cow's milk allergies. Moreover, research into donkey milk's potential for cancer prevention, diabetes management, and as a treatment for various diseases is ongoing, thanks to its bioactive peptides and components. Nevertheless, challenges such as its low production yield and the not fully understood mechanisms behind its potential therapeutic role necessitate more thorough investigation. This review consolidates the existing knowledge on the therapeutic possibilities of donkey milk, emphasizing its importance for human health and the need for more detailed studies to confirm its health benefits.

A prospective cohort study comparing monitored anesthesia care and intubated general anesthesia in cardiac surgery involving cardiopulmonary bypass.

BACKGROUND: The aim of this study is to assess the feasibility and safety of monitored anesthesia care (MAC) versus intubated general anesthesia (IGA) for patients undergoing elective cardiac surgery with cardiopulmonary bypass (CPB). METHODS: This prospective observational study included patients scheduled for cardiac surgery involving CPB at our institution between April 2012 and February 2017. The enrolled patients were categorized into MAC and IGA groups. MAC involved local anesthesia at the sternotomy site, sedation with dexmedetomidine, analgesia with remifentanil/sufentanil, and electroacupuncture (EA). Eleven patients underwent MAC, and 13 patients received IGA. There were no instances of conversion from MAC to IGA, and both groups exhibited no major complications. The demographic characteristics, baseline parameters, and operative variables were comparable between the two groups. RESULTS: Intraoperative opioid consumption was significantly lower in the MAC group compared to the IGA group (P < 0.001). The time to oral intake of liquids was significantly shorter in the MAC group (2.14 ± 0.90 h) compared to the IGA group (22.31 ± 3.33 h) (P < 0.001). Furthermore, the intensive care unit length of stay (ICU-LOS) and perioperative vasoactive-inotropic score (VIS) were significantly reduced in the MAC group compared to the IGA group (P < 0.001). CONCLUSIONS: MAC emerges as a safe and viable alternative to general anesthesia for specific patient groups undergoing cardiac surgery with CPB. Furthermore, it may enhance postoperative recovery and minimize postoperative complications compared to IGA.

An Overview of Bioactive Compounds' Role in Modulating the Nrf2/Keap1/NF-κB Pathway to Alleviate Lipopolysaccharide-Induced Endometritis.

Endometritis is a common inflammatory condition of the uterine endometrial lining that primarily affects perinatal dairy animals and causes significant economic losses in agriculture. It is usually triggered by pathogenic bacteria and is associated with chronic postpartum reproductive tract infections. Bacterial lipopolysaccharides (LPSs) are known to increase levels of reactive oxygen species (ROS), leading to oxidative stress and inflammation through the activation of the NF-κB signaling pathway and the inhibition of Nrf2 nuclear translocation, which regulates antioxidant response elements (AREs). The effectiveness of the conventional management strategy involving antibiotics is decreasing due to resistance and residual concerns. This review explores the potential therapeutic benefits of targeting the Nrf2/Kelch-like ECH-associated protein 1 (Keap1)/NF-κB signaling pathway to alleviate LPS-induced endometritis. We discuss recent advancements in veterinary medicine that utilize exogenous antioxidants to modulate these pathways, thereby reducing oxidative stress and inflammatory responses in endometrial cells. This review highlights the efficacy of several bioactive compounds that enhance Nrf2 signaling and suppress NF-κB activation, offering protective effects against oxidative damage and inflammation. By examining various in vitro studies, this review emphasizes the emerging role of these signaling pathways in developing new therapeutic strategies that could potentially replace or supplement traditional treatments and mitigate the economic impacts of endometritis in livestock.

Interactive effects of trust in government information and perceived value on Chinese consumers' actual purchasing behavior toward contaminated seafood.

Previous studies have separately examined the roles of trust in government information and perceived value in consumer food choices; however, the interactive effects of trust in government information and perceived value remain unknown. Therefore, this study explores the joint effects of trust in government information and perceived value on shaping consumers' actual food purchase behavior after food contamination. A logit model was used to estimate the interactive effects. The results from a sample of 710 Chinese consumers indicated that a lack of trust continues to make consumers concerned about the safety of seafood, which, together with the spread of internet rumors, leads to the fact that trust in government information does not directly affect consumers' actual purchase behavior. However, it can also indirectly influence purchase behavior through perceived risks and benefits. Specifically, trust in government information reduces risk perception among low-income consumers and enhances benefit perception among low-risk city consumers, thus enhancing purchasing behavior. Moreover, we find city heterogeneity in its impact on consumer purchasing behavior. Specifically, in low-risk cities, it significantly promotes consumer purchasing behavior, however, in high-risk cities, it does not directly affect consumer purchasing behavior. Overall, trust in government information does not directly affect consumer purchasing behavior. Perceived value is a key factor affecting consumer purchasing behavior. An interactive effect exists between trust in government information and perceived value on consumer purchasing behaviors. These results highlight the role of perceived value in amplifying the effects of trust in government information. These findings have significant implications for seafood producers and policymakers. Effective strategies should encompass both the provision of perceived value and the cultivation of trust in government information to promote consumer choices of contaminated food.

Patients were categorized into the control group (n = 50, receiving conventional treatment only) and experimental group (n = 50, receiving hetrombopag combined with conventional treatment). Before treatment and at weeks 18, 24, and 52 after treatment, the two groups were compared in routine blood test indicators, natural killer (NK) cell activity, and peripheral blood inflammatory factor levels. The overall remission rate and incidence of adverse events were also compared between the two groups. Outpatient or telephone follow-up was performed before treatment and at weeks 18, 24, and 52 after treatment to observe patients' immune function, treatment outcome, quality of life, and adverse events. Hemoglobin (Hb), and platelet count (PLT) (P < 0.05), and a rise in NK cell activity (P < 0.05). Interleukin (IL-10) levels were significantly higher, while IL-6 levels were significantly lower in the experimental group compared to the control group (P < 0.05). After receiving the treatment, all scores of SF-36 domains in both groups were higher than before treatment, particularly with higher scores in the experimental group (P < 0.05). Hetrombopag combined with conventional treatment improved the immune function and hematopoiesis of patients with SAA.

SLC8A1, a novel prognostic biomarker and immunotherapy target in RSA and UCEC based on scRNA-seq and pan-cancer analysis.

Background: The field of gynaecological immunology has increasingly focused on recurrent spontaneous abortion (RSA). The complex mechanisms underlying the interaction between RSA and cancer are not well understood. Methods: Weighted gene coexpression network analysis (WGCNA), single-cell RNA sequencing (scRNA-seq), and machine learning algorithms were used for the analysis of RSA decidua samples to identify the hub genes. The expression and distribution of the hub genes were subsequently investigated via the pancancer database TCGA. A prognostic prediction was made to assess the impact of the hub genes on the cancer response, mutation burden, immune microenvironment, immune checkpoint, and chemotherapy. In vitro assays were performed to determine whether SLC8A1 influences HTR-8/SVneo cell proliferation, apoptosis and the concentration of calcium ions. Results: SLC8A1 was identified as a hub gene within RSA and was highly expressed in uterine corpus endometrial carcinoma (UCEC). The efficacy of SLC8A1 as a predictive marker was substantiated by calibration curves and the concordance index. The mutation rate of SLC8A1 was found to be 6 % on the basis of the waterfall plot. Immune analysis revealed notable differences in the fractions of T cells and macrophages between the high- and low-expression groups. Patients classified in the low-risk group exhibited enhanced responsiveness to osimertinib, dasatinib, and ibrutinib. The results of in vitro experiments revealed that SLC8A1 promotes proliferation and inhibits the apoptosis and concentration of calcium ions in HTR-8/SVneo cells. Conclusion: These findings suggest that SLC8A1 may serve as a promising prognostic biomarker and potential target for immunotherapy in the context of RSA and UCEC.

Recent in vitro studies have emphasized the importance of the TLR2/TLR4/NF-κB signaling pathway in the development of mastitis, suggesting its potential as a therapeutic target. This review summarizes recent research on the role of the TLR2/TLR4/NF-κB signaling pathway in mastitis. It focuses on how the activation of TLRs leads to the production of proinflammatory cytokines, which, in turn, exacerbate the inflammatory response by activating the NF-κB signaling pathway in mammary gland tissues. Additionally, the review discusses various bioactive compounds and probiotics that have been identified as potential therapeutic agents for preventing and treating mastitis by targeting TLR2/TLR4/NF-κB signaling pathway. Overall, this review highlights the significance of targeting the TLR2/TLR4/NF-κB signaling pathway to develop effective therapeutic strategies against mastitis, which can enhance dairy cow health and reduce economic losses in the dairy industry.

Modulating Electrochemical Energy Storage and Multi-Spectra Defense of MXenes by Interfacial Dual-Filler Engineering.

MXenes have attracted growing interest in electrochemical energy storage owing to their high electronic conductivity and editable surface chemistry. Besides, rendering MXenes with spectrum defense properties further broadens their versatile applications. However, the development of MXenes suffers from weak van der Waal interaction-driven self-restacking that leads to random alignment and inferior interface microenvironments. Herein, a nacre-inspired MXene film is tailored by dual-filling of 2-ureido-4[1H]-pyrimidinone (UPy)-modified polyvinyl alcohol (PVA-UPy) and carbon nanotubes (CNTs). The dual-nanofillers engineering endows the nanocomposite film with a highly ordered structure (a Herman's order value of 0.838), a high mechanical strength (139.5 MPa), and continuous conductive pathways of both the ab plane and c-axis. As a proof-of-concept, the tailored nanocomposite film achieves a considerable capacitance of 508.2 F cm-3 and long-term cycling stability without performance degradation for 10 000 cycles. It is efficient for spectra defense in radar and infrared bands, displaying a high electromagnetic shielding capacity (19186 dB cm2 g-1) and a super-low infrared (IR) emissivity (0.16), with negligible performance decay after saving in the air for 1 year, responsible for the applications in specific and complex conditions. This interfacial dual-filler engineering concept showcases effective nanotechnology toward sustainable energy applications with a long lifetime and safety.

In Situ Polymerized Zwitterionic Copolymer Ionic Gel Electrolytes with High Performance for Lithium-Ion Batteries.

Gel electrolytes are a promising research direction due to their high safety. However, its poor room temperature conductivity along with complex preparation process hinder its practical application. In this article, a type of zwitterionic gel electrolyte is prepared by in situ polymerization. The introduction of charged but nonmigrating zwitterionic copolymer in the polymer chain is beneficial to the dissociation of the lithium salt, improving the ion transport of the electrolyte on this account. At room temperature, the conductivity of lithium ion reaches 9.1 × 10-4 S cm-1, which contributes to achieve excellent electrochemical performance at high rates. The assembled Li|LiFePO4 cell also shows a capacity retention rate of 90.5% after 150 cycles at 0.5 C at room temperature as well as remarkable cycle stability at 1 C. These offer a novel tactic for the efficient and safe commercial application of lithium-ion batteries.

Spatioselective Occlusion of Copolymer Nanoparticles within Calcite Crystals Generates Organic-Inorganic Hybrid Materials with Controlled Internal Structures.

Efficient occlusion of particulate additives into a single crystal has garnered an ever-increasing attention in materials science because it offers a counter-intuitive yet powerful platform to make crystalline nanocomposite materials with emerging properties. However, precisely controlling the spatial distribution of the guest additives within a host crystal remains highly challenging. We herein demonstrate a unique, straightforward method to engineer the spatial distribution of copolymer nanoparticles within calcite (CaCO3) single crystals by judiciously adjusting initial [Ca2+] concentration used for the calcite precipitation. More specifically, polymerization-induced self-assembly is employed to synthesize well-defined and highly anionic poly(3-sulfopropyl methacrylate potassium)41-block-poly(benzyl methacrylate)500 [PSPMA41-PBzMA500] diblock copolymer nanoparticles, which are subsequently used as model additives during the growth of calcite crystals. Impressively, such guest nanoparticles are preferentially occluded into specific regions of calcite depending on the initial [Ca2+] concentration. These unprecedented phenomena are most probably caused by dynamic change in electrostatic interaction between Ca2+ ions and PSPMA41 chains based on systematic investigations. This study not only showcases a significant advancement in controlling the spatial distribution of guest nanoparticles within host crystals, enabling the internal structure of composite crystals to be rationally tailored via a spatioselective occlusion strategy, but also provides new insights into biomineralization.

Editorial Perspective: Extending IPDMA methodology to drive treatment personalisation in child mental health.

To improve outcomes for youth who do not respond optimally to existing treatments, we need to identify robust predictors, moderators, and mediators that are ideal targets for personalisation in mental health care. We propose a solution to leverage the Individual Patient Data Meta-analysis (IPDMA) approach to allow broader access to individual-level data while maintaining methodological rigour. Such a resource has the potential to answer questions that are unable to be addressed by single studies, reduce researcher burden, and enable the application of newer statistical techniques, all to provide data-driven strategies for clinical decision-making. Using childhood anxiety as the worked example, the editorial perspective outlines the rationale for leveraging IPDMA methodology to build a data repository, the Platform for Anxiety Disorder Data in Youth. We also include recommendations to address the methods and challenges inherent in this endeavour.

Weak Solvation Chemistry in Fluorinated Nonflammable Electrolytes Achieves Stable Cycling in High-Voltage Lithium Metal Batteries.

High-voltage (>4.35 V) lithium nickel-cobalt-manganese batteries are star candidates due to their higher energy density for next-generation power batteries. This poses higher demands for electrolyte design, including compatibility with lithium metals, stability on high-voltage cathodes, speedy interfacial ion transport kinetics, and appropriate concentration. However, electrolytes at the current level of research struggle to balance these demands. Here, we took advantage of the reduced affinity with Li+ and enhanced oxidative stability of three fluorinated linear carbonates to design a series of weakly solvating electrolytes (WSEs) at a low salt concentration of 1 M, which contain abundant ionic cluster structures, leading to the optimization of interfacial chemistry. As a result, WSEs can support the stable cycling of 4.6 V high-voltage Li||NCM811 cells for 300 cycles with a capacity retention of nearly 80%. Moreover, benefiting from the lower desolvation energy of Li+, WSEs achieve superior cycling stability and low polarization under -20 °C. Our work extends the application of WSEs for high-voltage LMBs, providing a promising solution in electrolytes for high-specific-energy lithium batteries.

Hypoxia-inducible factor prolyl hydroxylase inhibitor alleviates heatstroke-induced acute kidney injury by activating BNIP3-mediated mitophagy.

Hypoxia-induced inflammation and apoptosis are important pathophysiological features of heat stroke-induced acute kidney injury (HS-AKI). Hypoxia-inducible factor (HIF) is a key protein that regulates cell adaptation to hypoxia. HIF-prolyl hydroxylase inhibitor (HIF-PHI) stabilizes HIF to increase cell adaptation to hypoxia. Herein, we reported that HIF-PHI pretreatment significantly improved renal function, enhanced thermotolerance, and increased the survival rate of mice in the context of HS. Moreover, HIF-PHI could alleviate HS-induced mitochondrial damage, inflammation, and apoptosis in renal tubular epithelial cells (RTECs) by enhancing mitophagy in vitro and in vivo. By contrast, mitophagy inhibitors Mdivi-1, 3-MA, and Baf-A1 reversed the renoprotective effects of HIF-PHI. Mechanistically, HIF-PHI protects RTECs from inflammation and apoptosis by enhancing Bcl-2 adenovirus E18 19-kDa-interacting protein 3 (BNIP3)-mediated mitophagy, while genetic ablation of BNIP3 attenuated HIF-PHI-induced mitophagy and abolished HIF-PHI-mediated renal protection. Thus, our results indicated that HIF-PHI protects renal function by upregulating BNIP3-mediated mitophagy to improve HS-induced inflammation and apoptosis of RTECs, suggesting HIF-PHI as a promising therapeutic agent to treat HS-AKI.
