Condiments (such as sodium chloride and glutamate sodium) cause consumers to ingest too much sodium and may lead to a variety of diseases, thus decreasing their quality of life. Recently, a salt reduction strategy using flavor peptides has been established. However, the development of this strategy has not been well adopted by the food industry. There is an acute need to screen for peptides with salty and umami taste, and to understand their taste characteristic and taste mechanism. This review provides a thorough analysis of the literature on flavor peptides with sodium-reducing ability, involving their preparation, taste characteristic, taste mechanism and applications in the food industry. Flavor peptides come from a wide range of sources and can be sourced abundantly from natural foods. Flavor peptides with salty and umami tastes are mainly composed of umami amino acids. Differences in amino acid sequences, spatial structures and food matrices will cause different tastes in flavor peptides, mostly attributed to the interaction between peptides and taste receptors. In addition to being used in condiments, flavor peptides have also anti-hypertensive, anti-inflammatory and anti-oxidant abilities, offering the potential to be used as functional ingredients, thus making their future in the food industry extremely promising.

Transition metal selenides (TMSes) are considered promising candidates for the anodes of sodium‐ion batteries (SIBs) due to their substantial theoretical capacity. However, TMSes still face with inferior cycling lifespan caused by sluggish Na+ diffusion kinetics and vigorous volume variations during dis/charge processes. Engineering heterostructure is an attractive solution for rapid Na+ transfer, and introducing carbonaceous materials also facilitates enhanced conductivity and structural stability. Herein, CoSe/MoSe2 heterostructure combined with homogeneous carbon composites are rational designed. The kinetic analysis and theoretical calculations verified that heterointerface engineering induced build‐in electric field effect can amplifies the Na+ diffusion kinetics, while carbon contributes to enhanced electrical conductivity and structural stability. Expectedly, the CoSe/MoSe2‐C exhibits high capacity and extremely ultra‐long lifespan (320.9 mAh g−1 at 2.0 A g−1 over 10,000 cycles with an average decay of only 0.01781 mAh g−1 per cycle). Furthermore, in situ X‐ray diffraction (XRD), ex situ X‐ray photoelectorn (XPS), and high‐resolution electron microscopy (HRTEM) are exploited to explore the Na+ storage mechanism. In addition, the Na3V2(PO4)3@rGO//CoSe/MoSe2‐C (NVP@rGO//CoSe/MoSe2‐C) pouch‐type full‐cells are successfully assembled and delivered satisfactory performance. This research presents a viable strategy for the targeted engineering of TMSes aimed at enhancing the efficiency of SIBs. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) is a major fatal cancer that is known for its high recurrence and metastasis. An increasing number of studies have shown that the tumor microenvironment is closely related to the metastasis and invasion of HCC. The HCC microenvironment is a complex integrated system composed of cellular components, the extracellular matrix (ECM), and signaling molecules such as chemokines, growth factors, and cytokines, which are generally regarded as crucial molecules that regulate a series of important processes, such as the migration and invasion of HCC cells. Considering the crucial role of signaling molecules, this review aims to elucidate the regulatory effects of chemokines, growth factors, and cytokines on HCC cells in their microenvironment to provide important references for clarifying the development of HCC and exploring effective therapeutic targets.

Background: Exposure to indoor air pollution from solid cooking fuel use may increase mental disorders risk through pathways such as oroxidative stress, neuroinflammation, or cerebrovascular damage. However, few studies have explored the underlying mechanism between solid cooking fuel use and psychological distress. The present study aims to investigate the mediating role of sleep quality on the relationship between solid cooking fuel use and psychological distress among older adults in rural Shandong, China. Methods: This study used the cross-sectional data from the second follow-up survey of the Shandong Rural Elderly Health Cohort (SREHC). A total of 3,240 rural older adults were included in the analysis. Logistic regression and the Karlson, Holm, and Breen (KHB) mediation analyses were performed to investigate the relationship between solid cooking fuel use and psychological distress, as well as the mediating role of sleep quality in this association. Results: This study found that solid cooking fuel use was significantly and positively associated with psychological distress among older adults in rural Shandong, China (OR = 1.38, 95% CI: 1.12,1.70). Mediation analysis revealed that sleep quality mediated the association between solid cooking fuel use and psychological distress among older adults (β = 0.06, P = 0.011). The mediation effect accounted for 16.18% of the total effect. Conclusions: Our study showed that solid cooking fuel use was associated with psychological distress among rural older adults, and sleep quality mediated this association. Interventions should focus on addressing cooking fuel types and poor sleep quality to reduce psychological distress. In the future, more aggressive environmental protection policies would be needed to lessen the adverse effects of indoor air pollution on the health of older adults in rural China.

The manipulation of the energy or source of food for cancer cells has attracted significant attention in oncology research. Metabolic reprogramming of the immune system allows for a deeper understanding of cancer cell mechanisms, thereby impeding their progression. A more targeted approach is the restriction of cancer cells through dietary restriction (CR), which deprives cancer cells of the preferred energy sources within the tumor microenvironment, thereby enhancing immune cell efficacy. Although there is a plethora of CR strategies that can be employed to impede cancer progression, there is currently no comprehensive review that delineates the specific dietary restrictions that target the diverse metabolic pathways of cancer cells. This mini-review introduces amino acids as anti-cancer agents and discusses the role of dietary interventions in cancer prevention and treatment. It highlights the potential of a ketogenic diet as a therapeutic approach for cancer, elucidating its distinct mechanisms of action in tumor progression. Additionally, the potential of plant-based diets as anti-cancer agents and the role of polyphenols and vitamins in anti-cancer therapy were also discussed, along with some prospective interventions for CR as anti-tumor progression.

In this paper, tracking control of a class of series elastic actuators subject to unknown time-varying input delay and additive disturbances is investigated. To address the input delay, a novel predictor-like method is proposed in the control input which uses a predictor to compensate for the delay. Lyapunov-Krasovskii functions are applied within Lyapunov-based stability analysis to show semi-globally uniformly ultimately bounded tracking errors. The control scheme is extended to the case that the input delay is unknown and time-varying. A constant estimate of the delay is determined to establish uniformly ultimately bounded convergence of the tracking error. Numerical simulation results illustrate the performance of the developed robust controller. [ABSTRACT FROM AUTHOR]

Leaf width is a key determinant of planting density and photosynthetic efficiency. In an effort to determine which genes regulate maize plant leaf width, we performed a genome-wide association study (GWAS) of 1.49 × 106 single nucleotide polymorphisms (SNPs) in 80 sequenced backbone inbred maize lines in Jilin Province, China, based upon phenotypic leaf width data from two years. In total, 14 SNPs were identified as being significantly related to leaf width (p < 0.000001), with these SNPs being located on chromosomes 1, 2, 3, 5, 6, 7, 8, and 9. A total of five candidate genes were identified within a mean linkage disequilibrium (LD) distance of 9.7 kb, with a significant SNP being identified within the Zm00001d044327 candidate gene. RNA was then isolated from 12 different inbred maize lines from this GWAS study cohort and was used to conduct qPCR analyses which revealed significant differences in Zm00001d044327 expression among strains exhibiting significant differences in leaf width. Based on an assessment of EMS mutant lines harboring a conserved amino acid stop mutation and two non-synonymous mutations in Zm00001d044327 that exhibited a narrow leaf width, these data suggested that Zm00001d044327 is a key regulator of maize leaf width.

bZIP transcription factors play important roles in regulating plant development and stress responses. Although bZIPs have been identified in many plant species, there is little information on the bZIPs in Chrysanthemum. In this study, bZIP TFs were identified from the leaf transcriptome of C. mongolicum, a plant naturally tolerant to drought. A total of 28 full-length bZIP family members were identified from the leaf transcriptome of C. mongolicum and were divided into five subfamilies based on their phylogenetic relationships with the bZIPs from Arabidopsis. Ten conserved motifs were detected among the bZIP proteins of C. mongolicum. Subcellular localization assays revealed that most of the CmbZIPs were predicted to be localized in the nucleus. A novel bZIP gene, designated as CmbZIP9, was cloned based on a sequence of the data of the C. mongolicum transcriptome and was overexpressed in tobacco. The results indicated that the overexpression of CmbZIP9 reduced the malondialdehyde (MDA) content and increased the peroxidase (POD) and superoxide dismutase (SOD) activities as well as the expression levels of stress-related genes under drought stress, thus enhancing the drought tolerance of transgenic tobacco lines. These results provide a theoretical basis for further exploring the functions of the bZIP family genes and lay a foundation for stress resistance improvement in chrysanthemums in the future.

Parasitic electrolyte reactions and dendrite growth make Zn metal anodes with high Zn utilization rates (ZURs) more inaccessible, holding back the advance of aqueous zinc metal batteries (AZMBs). Here, sodium isoascorbate (SIA) is introduced to aqueous electrolytes as a self‐deoxidizing and self‐dehydrogenating additive. Coexisting C6H7O6−/C6H5O6− couple spontaneously captures dissolved oxygen and eliminates generated hydrogen by acting as a redox buffer, which leads to the creation of antioxidant Interfaces due to an in situ formed ZnCO3‐dominated solid electrolyte interphase (SEI). This SEI enables the (100) faceted electrode with dendrite‐free and non‐corrosive Zn plating/stripping, thus yielding a Coulombic efficiency of 99.7% up to 1100 h at 5 mAh cm−2, as well as a stable cycle sustaining for over 335 h under a high ZUR of 85.5%. Full‐cell properties are demonstrated by matching a poly(3,4‐ethylenedioxythiophene) intercalated vanadium oxide (PEDOT‐V2O5) cathode, which harvests a high capacity of 302 mAh g−1 (at 0.01 A g−1) and holds 94.2% capacity retention over 600 cycles (at 1 A g−1) under practical conditions (N/P = 4.2 and E/C = 7.6 µL mg−1). These findings provide a new solution for electrolyte design for industrializing AZMBs. [ABSTRACT FROM AUTHOR]

Objective: Employing network pharmacology and molecular docking, the study predicts the active compounds in garlic and elucidates their mechanism in inhibiting the development of alcoholic liver disease (ALD). ALD is a global chronic liver disease with potential for hepatocellular carcinoma progression. Methods: The main active ingredients and targets of garlic were identified through screening the TCMSP, TCM-ID, and ETCM databases. ALD disease targets were sourced from DisGeNET, GeneCards, and DiGSeE databases, and intervention targets for garlic were determined through intersections. Protein interaction networks were constructed using the STRING platform, and GO and KEGG pathway enrichment analyses were performed with R software. The garlic component-disease-target network was established using Cytoscape software. Validation of active ingredients against core targets was conducted through molecular docking simulations using AutoDock Vina software. Expression validation of core targets was carried out using human sequencing data of ALD obtained from the GEO database. Results: Integration of garlic drug targets with ALD disease targets identified 83 target genes. Validation through an alcohol-induced ALD mouse model supported certain network pharmacology findings, suggesting that garlic may impede disease progression by mitigating the inflammatory response and promoting ethanol metabolism. Conclusion: This study provides insights into the potential therapeutic mechanisms of garlic in inhibiting ALD development. The identified active ingredients offer promising avenues for further investigation and development of treatments for ALD, emphasizing the importance of botanical remedies in liver disease management.

There are many common malignant tumors in clinic. Among them, lung cancer is caused by the failure of suction system, which seriously threatens the life safety of patients. Recent studies have found that anesthetics have achieved certain efficacy in many cancers. Isoflurane, an inhaled anesthetic, is used in this study to explore whether it can prevent the lung cancer development. The A549 and H1299 were purchased. Cell viability was tested by CCK-8 experiment. Cell death and pyroptosis were analyzed by PI staining as well as flow cytometry. HMGB1 as well as RAGE protein levels were tested by Western blot. The same is true of pyroxin-related proteins. The HMGB1 as well as RAGE levels in the lung cancer tissues were determined by Western blot along with immunohistochemistry. Isoflurane treatment can reduce cell viability and promote cell pyroptosis. Additionally, the protein levels of cleaved caspase-1, IL-1β, GSDMD-N, NLRP3, HMGB1, and RAGE were dramatically up-regulated in the lung cancer after isoflurane treatment. Down-regulated proteins in lung cancer tissues include HMGB1 and RAGE proteins. After HMGB1 knockdown or FPS-ZM1 treatment, the role of isoflurane in the lung cancer was neutralized. This study demonstrated that isoflurane induced the cell pyroptosis in the lung cancer through activating the HMGB1/RAGE pathway. [ABSTRACT FROM AUTHOR]

This study aimed to explore the latent profiles of peer attachment and parent-child relationships and longitudinal transition patterns for within-person and within-sample profiles among a cohort of high school students. A cohort of 453 participants from China completed the above-mentioned measures with a six-month interval from grade 10 to 11. This study included 64.0% girls and 36.0% boys. Latent profile analysis (LPA) was used to explore the distinct profiles reflecting different response patterns for peer attachment and parent-child relationships at each time point. Latent transition analysis (LTA) was adopted to examine the membership of distinct latent profiles and how individuals move between profiles over time. Three latent profiles were identified with poor, moderate and good peer attachment and parent-child relationships. The stability of the same profile ranged from 0.601 to 0.803. The lowest transition probability was found between the poor and good profiles, whereas a higher transition probability from the poor and good profiles to the moderate profile was demonstrated. Patterns of peer attachment and parent-child relationships were associated with depression, anxiety, and Internet addiction (IA). This study advanced the knowledge of the heterogeneity and variation in peer attachment and parent-child relationships by a person-centered approach in a longitudinal study. The findings of the study direct selective interventions to populations with poor attachment and parent-peer relationships, and transitions from good to poor attachment direction across latent profiles of attachment and parent-peer relationships. Establishing secure attachment with peers and having good parent-child relationships may contribute to good adolescents' mental health and protect them from excessive Internet use. Highlights: There were three distinct profiles of peer attachment and parent-child relationships in a cohort of high school students. These identified profiles were transient between two measurement waves. Profiles of peer attachment and parent-child relationships were associated with depression, anxiety, and Internet addiction (IA). [ABSTRACT FROM AUTHOR]

Both the intrinsic and extrinsic contributions to the high energy storage properties of (K0.5Na0.5)NbO3 were investigated herein by employing Bi(Mg2/3Ta1/3)O3 as a second component to synthesize novel environment‐friendly energy storage ceramics. The role of the second component was confirmed to reduce the intrinsic activation of electrons, which effectively improves the band gap values and reduces the probability of intrinsic breakdown. Phase field simulation was employed to confirm that the smaller grain size of the modified ceramic microstructure enhances the extrinsic breakdown and dielectric breakdown strength. Moreover, ab initio molecular dynamics were used to investigate the critical role of the Mg ions in lowering the initial polarization and forming nanodomains, representing the intrinsic contribution to decreasing the initial polarization. An intrinsic structure with moderate polarization rapidly increases the polarization of ceramics under external electric fields, facilitating high energy storage density. The prepared ceramics achieve a recoverable energy density (Wrec) of 3.86 J/cm3 and energy efficiency (η) of 81.2% at 385 kV/cm. [ABSTRACT FROM AUTHOR]

For dielectric capacitors in pulsed power systems, ultrafast charge‐discharge rates and good energy storage performances are essential. The relatively low efficiency η and the low energy density of potassium sodium niobate ceramics will restrict their applications. In this work, a local distortion of the crystal structure of ceramics is made by introducing the Bi and Ce ions, promoting the growth of polar nano‐regions, resulting in more obvious relaxation behavior and lower remnant polarization Pr. The average grain size is reduced, further increasing of breakdown strength. Eventually, fine comprehensive energy storage performances and good mechanical properties are simultaneously obtained. Enhanced recoverable energy storage density Wrec (∼5.30 J/cm3) and a high energy storage efficiency η (∼76.81%) are achieved in 0.970(K0.5Na0.5)NbO3‐0.030CeBiO3 (KNN‐0.030CB) ceramics with an ultrafast discharge rate t0.9 (31 ns) and a high current density (1008.5 A/cm2). All of these results indicate that this work provides a resultful way to design excellent comprehensive properties for advanced energy storage materials. [ABSTRACT FROM AUTHOR]

Interfacial solar‐vapor generation (ISVG) is an emerging technology for water purification. However, high cost, low evaporation rate, clogging issues, and limited solar utilization under natural condictions greatly hinder its practical application. Herein, inspired by the aligned microstructure of dragonfly wings, a 3D microarray structure composed of vertically aligned hierarchical and hydrophilic carbon fibers (CFs) is constructed using a scalable fiber manufacturing technology. The microarray structure of the high‐thermal‐conductivity CFs with nanocapillaries contributes to the fast mass (steam and salt ions) and heat transfer as well as high omnidirectional light absorption. More importantly, due to the strong multiscale capillary effect, the formed 3D water evaporation surface containing abundant micro‐meniscuses and nanoscale thin water layers in the CFs arrays effectively reduces the evaporation enthalpy and creates more water/air interfaces, leading to the significant increasing evaporation rate. As a result, a high evaporation rate of 2.21 kg m−2 h−1 under one‐sun irradiation can be achieved. Moreover, the off‐grid water treatment device assembled with multiple 3D CFs‐based customized spherical evaporators can obtain a high pure water collection of 10.71 kg m−2 per day without salt accumulation under real environmental conditions. This work demonstrates a high‐efficiency, cost‐effective, and scalable strategy for high‐performance ISVG. [ABSTRACT FROM AUTHOR]

Wastewater containing organic dyes has become one of the important challenges in water treatment due to its high salt content and resistance to natural degradation. In this work, a novelty adsorbent, PEI-SMA, was prepared by grafting polyethyleneimine (PEI) onto styrene-maleic anhydride copolymer (SMA) through an amidation reaction. The various factors, such as pH, adsorbent dosage, contact time, dye concentration, and temperature, which may affect the adsorption of PEI-SMA for Reactive Black 5 (RB5), were systematically investigated by static adsorption experiments. The adsorption process of PEI-SMA for RB5 was more consistent with the Langmuir isotherm model and the pseudo-second-order model, suggesting a single-layer chemisorption. PEI-SMA exhibits excellent adsorption performance for RB5 dye, with a maximum adsorption capacity of 1749.19 mg g–1 at pH = 2. Additionally, PEI-SMA exhibited highly efficient RB5 competitive adsorption against coexisting Cl− and SO42− ions and cationic dyes. The adsorption mechanism was explored, and it can be explained as the synergistic effect of electrostatic interaction, hydrogen bonding and π–π interaction. This study demonstrates that PEI-SMA could act as a high performance and promising candidate for the effective adsorption of anionic dyes from aqueous solutions. [ABSTRACT FROM AUTHOR]

The current study was aimed to determine depression as a mediator as well as the social support as a moderator playing in the link of bullying victimization with phubbing. A cross-sectional research on 758 students was conducted using a cluster sampling method in a Chinese public middle school. Levels of bullying victimization, depression, social support and phubbing were self-reported by participants in standard measures. Bullying victimization showed significant positive correlation with depression (b = 0.35, p < 0.001), and depression also was positively linked to phubbing (b = 0.36, p < 0.001), after taking sex and age into account. The indirect effect of bullying victimization through depression to phubbing was 0.12. Social support played the protective effect as a moderator on the path from bullying victimization to depression (b = 0.29, p<0.001). Specifically, the impact of higher bullying victimization on depression risk was less robust in individuals reporting high levels of social support (훽simple=0.15, t = 2.80, p<0.01) than those of a decreased social support (훽simple=0.43, t = 9.22, p<0.001). The relief of depressive symptoms is beneficial for a less negative impact of bullying victimization on phubbing. Targeted intervention programs could focus on social support to ameliorate the adverse sequelae of bullying victimization and minimize the prevalence of mental and behavioral problems by reducing the occurrence of victimization experience.

Background: Atherosclerosis (AS) is a persistent inflammatory condition triggered and exacerbated by several factors including lipid accumulation, endothelial dysfunction and macrophages infiltration. Nobiletin (NOB) has been reported to alleviate atherosclerosis; however, the underlying mechanism remains incompletely understood. Methods: This study involved comprehensive bioinformatic analysis, including multidatabase target prediction; GO and KEGG enrichment analyses for function and pathway exploration; DeepSite and AutoDock for drug binding site prediction; and CIBERSORT for immune cell involvement. In addition, target intervention was verified via cell scratch assays, oil red O staining, ELISA, flow cytometry, qRT‒PCR and Western blotting. In addition, by establishing a mouse model of AS, it was demonstrated that NOB attenuated lipid accumulation and the extent of atherosclerotic lesions. Results: (1) Altogether, 141 potentially targetable genes were identified through which NOB could intervene in atherosclerosis. (2) Lipid and atherosclerosis, fluid shear stress and atherosclerosis may be the dominant pathways and potential mechanisms. (3) ALB, AKT1, CASP3 and 7 other genes were identified as the top 10 target genes. (4) Six genes, including PPARG, MMP9, SRC and 3 other genes, were related to the M0 fraction. (5) CD36 and PPARG were upregulated in atherosclerosis samples compared to the normal control. (6) By inhibiting lipid uptake in RAW264.7 cells, NOB prevents the formation of foam cell. (7) In RAW264.7 cells, the inhibitory effect of oxidized low-density lipoprotein on foam cells formation and lipid accumulation was closely associated with the PPARG signaling pathway. (8) In vivo validation showed that NOB significantly attenuated intra-arterial lipid accumulation and macrophage infiltration and reduced CD36 expression. Conclusions: Nobiletin alleviates atherosclerosis by inhibiting lipid uptake via the PPARG/CD36 pathway. [ABSTRACT FROM AUTHOR]

Simple Summary: The global cancer report for 2020 highlights a noteworthy surge in new cases of breast cancer, exceeding lung cancer incidence for the first time and emerging as the foremost global cancer manifestation. Breast cancer has become a prominent contributor to female cancer-related mortality. Surgical removal continues to be a primary therapeutic recourse for breast cancer patients, aiming to extend survival by addressing residual tumor foci during surgery. However, the challenge lies in achieving complete excision due to the ambiguous boundaries of tumors. NIR-II imaging, known for its heightened sensitivity, superior spatiotemporal resolution, and enhanced optical penetration depth compared to conventional optical imaging, stands out as an optimal choice for preoperative and real-time intraoperative imaging, particularly in live fluorescence imaging. Within this study, rare-earth nanoparticles α-Er NPs exhibit remarkable imaging quality in breast cancer, incorporating X-ray computed tomography and ultrasound, collectively enhancing precision in cancer diagnosis and treatment. Additionally, the study explores the photothermal therapeutic effects of α-Er NPs. Through the combination of NIR-II imaging technology with rare-earth probes, the research pioneers a secure and effective novel strategy for the precise diagnosis and treatment integration of breast cancer, establishing a robust foundation for future advancements in medical applications. Nanotheranostic agents capable of simultaneously enabling real-time tracking and precise treatment at tumor sites play an increasingly pivotal role in the field of medicine. In this article, we report a novel near-infrared-II window (NIR-II) emitting downconversion rare-earth nanoparticles (RENPs) to improve image-guided therapy for breast cancer. The developed α-NaErF4@NaYF4 nanoparticles (α-Er NPs) have a diameter of approximately 24.1 nm and exhibit superior biocompatibility and negligible toxicity. RENPs exhibit superior imaging quality and photothermal conversion efficiency in the NIR-II range compared to clinically approved indocyanine green (ICG). Under 808 nm laser irradiation, the α-Er NPs achieve significant tumor imaging performance and photothermal effects in vivo in a mouse model of breast cancer. Simultaneously, it combines X-ray computed tomography (CT) and ultrasound (US) tri-modal imaging to guide therapy for cancer. The integration of NIR-II imaging technology and RENPs establishes a promising foundation for future medical applications. [ABSTRACT FROM AUTHOR]

Endogenous essential metal ions play an important role in many life processes, especially in tumor development and immune response. The approval of various metallodrugs for tumor therapy brings more attention to the antitumor effect of metal ions. With the deepening understanding of the regulation mechanisms of metal ion homeostasis in vivo, breaking intracellular metal ion homeostasis becomes a new means to inhibit the proliferation of tumor cells and activate antitumor immune response. Diverse nanomedicines with the loading of small molecular ion regulators or metal ions have been developed to disrupt metal ion homeostasis in tumor cells, with higher safety and efficiency than free small molecular ion regulators or metal compounds. This comprehensive review focuses on the latest progress of various intracellular metal ion homeostasis regulation‐based nanomedicines in tumor therapy including calcium ion (Ca2+), ferrous ion (Fe2+), cuprous ion (Cu+), managanese ion (Mn2+), and zinc ion (Zn2+). The physiological functions and homeostasis regulation processes of ions are summarized to guide the design of metal ion regulation‐based nanomedicines. Then the antitumor mechanisms of various ions‐based nanomedicines and some efficient synergistic therapies are highlighted. Finally, the challenges and future developments of ion regulation‐based antitumor therapy are also discussed, hoping to provide a reference for finding more effective metal ions and synergistic therapies.

Wastewater containing dyes is frequently discharged by industrial processes and needs separation and recycling. To solve this problem, it is important to research and develop environmentally friendly, efficient adsorbent materials for pollutant separation and recovery. In this study, a poly(PEI‐catechol‐tetraethylenepentamine) (PPCT) adsorbent was synthesized using a simple catecholamine reaction. This adsorbent exhibited high adsorption capacity and excellent removal efficiency for Reactive Red 195 (RR‐195) in wastewater. The material was characterized using SEM, FT‐IR, TGA, EA, and XPS. Its performance was optimized by varying the type of polyethyleneimine and the amount added during the preparation process. The effects of temperature, pH, contact time, and salt concentration on the adsorption were systematically investigated. Additionally, the experimental data showed consistency with both the Langmuir and pseudo‐second‐order kinetic models, simultaneously. The maximum adsorption capacity can reach 1754 mg g−1 at 303 K, with a retention rate of 86.6% after two cycles. The removal rate exceeds 98% at a concentration of 400 mg g−1 or lower. Additionally, the protonated amine group in PPCT carries a positive charge under acidic conditions, enabling selective adsorption of the anionic dye RR‐195. Consequently, PPCT exhibits an excellent adsorption effect on RR‐195 and holds promising applications in pollutant removal. [ABSTRACT FROM AUTHOR]

Background: This study investigated the relationship between activities of daily living (ADL) limitations and the use of physical examination among older adults receiving informal care, and to further examine whether this relationship varies by gender and urban-rural areas. Methods: The data in this study were obtained from the sixth Health Service of Shandong province, China. In total, 8,358 older adults aged 60 years or older who received informal care were included in the analysis. Binary logistic regression models were conducted to explore the association between ADL limitations and the use of physical examination and examine the differences between gender and urban-rural areas. Results: The prevalence of limitations in ADL and physical examination utilization rate among older adults receiving informal care in Shandong Province were 14.12% and 72.31%, respectively. After adjusting for confounders, ADL limitations were negatively correlated with the utilization of physical examination services among older adults receiving informal care (OR = 0.74, 95% CI: 0.64, 0.87, P < 0.001), and there were gender and rural-urban differences. The association between ADL limitations and the use of physical examination was statistically significant in older women receiving informal care (OR = 0.65, 95% CI: 0.53, 0.80, P < 0.001). And only among urban older adults receiving informal care, those with ADL limitations had lower utilization of physical examination services than participants without ADL limitations (OR = 0.59, 95% CI: 0.47, 0.74, P < 0.001). Conclusions: Our study suggested that the relationship between ADL limitations and the use of physical examination among older adults receiving informal care differed by gender and urban-rural areas in Shandong, China. These findings implied that the government should provide more health resources and personalized physical examination service programs, especially to meet the differential needs of women and urban old adults receiving informal care, to contribute to the implementation of healthy aging strategies.

Background: Single-nucleotide polymorphisms (SNPs) are the most widely used form of molecular genetic variation studies. As reference genomes and resequencing data sets expand exponentially, tools must be in place to call SNPs at a similar pace. The genome analysis toolkit (GATK) is one of the most widely used SNP calling software tools publicly available, but unfortunately, high-performance computing versions of this tool have yet to become widely available and affordable. Results: Here we report an open-source high-performance computing genome variant calling workflow (HPC-GVCW) for GATK that can run on multiple computing platforms from supercomputers to desktop machines. We benchmarked HPC-GVCW on multiple crop species for performance and accuracy with comparable results with previously published reports (using GATK alone). Finally, we used HPC-GVCW in production mode to call SNPs on a "subpopulation aware" 16-genome rice reference panel with ~ 3000 resequenced rice accessions. The entire process took ~ 16 weeks and resulted in the identification of an average of 27.3 M SNPs/genome and the discovery of ~ 2.3 million novel SNPs that were not present in the flagship reference genome for rice (i.e., IRGSP RefSeq). Conclusions: This study developed an open-source pipeline (HPC-GVCW) to run GATK on HPC platforms, which significantly improved the speed at which SNPs can be called. The workflow is widely applicable as demonstrated successfully for four major crop species with genomes ranging in size from 400 Mb to 2.4 Gb. Using HPC-GVCW in production mode to call SNPs on a 25 multi-crop-reference genome data set produced over 1.1 billion SNPs that were publicly released for functional and breeding studies. For rice, many novel SNPs were identified and were found to reside within genes and open chromatin regions that are predicted to have functional consequences. Combined, our results demonstrate the usefulness of combining a high-performance SNP calling architecture solution with a subpopulation-aware reference genome panel for rapid SNP discovery and public deployment.

Bile acids (BAs) are involved in the development of necrotizing enterocolitis (NEC), which mainly occurs in preterm infants. We aim to identify the change of BAs in preterm infants and validate its potential value in the detection of NEC. Targeted liquid chromatography–tandem mass spectrometry (LC-MS/MS) was performed to measure the plasma BAs in healthy preterm infants and patients with NEC. By analyzing the level of BAs in healthy preterm infants, we found that the plasma concentrations of BAs were related to sex, gestational/postnatal age, birth weight, mode of birth, and feeding type after birth. The plasma levels of TCA, GCA, TCDCA, GCDCA, primary BAs, and total BAs and the primary/secondary BA ratio were decreased, while DCA, UDCA, and secondary BAs were increased in NEC. The primary/secondary BA ratio (cutoff point 62.9) can effectively differentiate NEC from healthy preterm infants, with an AUC of 0.9, a sensitivity of 94.5%, and a specificity of 78.1%. Combining the ratio with high-risk factors of NEC can better distinguish between NEC and control, with an AUC of 0.95. Importantly, significantly lower levels of primary/secondary BA ratio were found in infants with surgical NEC than in nonsurgical NEC cases. The cutoff point of 28.7 identified surgical NEC from nonsurgical NEC with sensitivity and specificity of 76.9% and 100%. Thus, our study identified that the primary/secondary BA ratio in the plasma can differentiate NEC from healthy preterm infants and effectively differentiate the surgical NEC from nonsurgical NEC. Therefore, LC-MS/MS was expected to be a novel measurement platform used to distinguish infants who are most in need of close monitoring or early surgical intervention. [ABSTRACT FROM AUTHOR]

Contrast-induced acute kidney injury (CI-AKI) has become the third leading cause of hospital-acquired kidney injury. A comprehensive analysis of the current state of research in the field of CI-AKI will help to reveal trends and hot topics in the field. To date, there are no published bibliometric analyses related to CI-AKI studies. Here, we analyze the relevant literature since the emergence of the concept and provide valuable insights. The literature was collected from the Web of Science Core Collection. The data were analyzed visually using CiteSpace and VOSviewer software. We collected a total of 4775 papers, with the United States and Guangdong Acad Med Sci as the major publishing powers in terms of country/region and institution. J AM COLL CARDIOL was the journal with the most published and cocited articles. Cluster analysis showed that clinical trials are the current research hotspot. The areas of risk assessment, prevention strategies, risk factors, and vascular lesions have been popular in recent years. Research on the mechanism of injury in CI-AKI will be the focus of future research, which will be crucial to reduce the clinical incidence of CI-AKI. In summary, this study provides a comprehensive analysis of the development process in the field of CI-AKI and discusses future research directions based on the analysis of objective data from many studies on CI-AKI.

Background: Contrast-induced acute kidney injury (CI-AKI) is considered to be the third leading cause of hospital-acquired kidney injury. Current studies mostly suggest that contrast agents mainly harm renal tubular epithelial cells, but we hypothesized that the development of CI-AKI should be the result of the interaction of renal vascular and tubular injury.Methods: First we constructed a CI-AKI mouse model and verified the success of the model by pathological injury and serum creatinine level. Immunohistochemistry, protein quantification and qRT-PCR were used to detect the location and level of expression of neutrophil extracellular traps (NETs) in the kidney. Then, we blocked the in vivo accumulation of NETs using GSK484 and DNase I and detected the expression of NETs and the damage of glomerular and peritubular capillaries.Results: We first identified the presence of NETs in CI-AKI mice, and NETs were mainly accumulated in glomeruli and peritubular capillaries. The expression of NETs was positively correlated with the severity of CI-AKI kidney. After inhibition of NETs release or promotion of NETs degradation by drugs, renal vascular endothelial cell injury was reduced and renal pathological changes and creatinine levels were reversed in CI-AKI mice. In addition, inhibition of NETs reduced apoptosis and pyroptosis of renal cells and attenuated inflammation in vivo.Conclusion: These findings suggest that NETs are involved in the development of CI-AKI by damaging glomerular and peritubular capillary endothelial cells. This study will provide a new strategy for clinical prevention and treatment of CI-AKI. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to evaluate the relationship between activities of daily living (ADL) limitations and family doctor contract services among overweight and obese older adults, as well as to examine whether this association varies by urban-rural residence. Methods: Data for the present study were obtained from the sixth Health Service of Shandong province, China. A total of 4,249 overweight and obese older adults were included in this study. Binary logistic regression models were used to evaluate the relationship between ADL limitations and family doctor contract services, to examine the potential differences between urban and rural areas. Results: Of 4,249 overweight and obese older adults, the prevalence of limitations in ADL and family doctor service contracting rate in Shandong province were 12.47% and 66.46%, respectively. The results of the regression analyses revealed that overweight and obese older adults with ADL limitations were more likely to sign up for family doctor services than those without ADL limitations (OR = 1.27, 95%CI: 1.02–1.58, P = 0.033). Only among rural overweight and obese older adults, the relationship between ADL limitations and family doctor contract services was statistically significant (OR = 1.50, 95%CI: 1.13–1.99, P = 0.005). Conclusions: Our study found a significant association between ADL limitations and family doctor contract services among overweight and obese older adults in Shandong, China. This relationship differed by urban-rural residence. To promote the positive development of the family doctor contract service system, the government should increase publicity, provide personalized contracted services, and prioritize the healthcare needs of overweight and obese older adults with ADL limitations, with special attention to rural areas.

Background: Non‐small cell lung cancer (NSCLC) is the most common type of lung cancer with high morbidity and mortality. The role of dysregulated circular RNAs (circRNAs) in human diseases are receiving more and more attention. In this study, we focused on the role and mechanism of circPKM2 in the progression of NSCLC. Methods: The expression levels of circPKM2, microRNA‐1298‐5p (miR‐1298‐5p) and metadherin (MTDH) in NSCLC were measured by real‐time quantitative PCR (qRT‐PCR) or Western blot. Cell counting kit‐8 (CCK‐8), colony formation, 5‐ethynyl‐2′‐deoxyuridine (EdU) staining, flow cytometry, transwell and tube formation assays were conducted to evaluate the effects of circPKM2 on malignant phenotypes of NSCLC. Western blot was used to measure related marker protein levels. Results: CircPKM2 and MTDH were highly expressed in NSCLC tissues and cells, while miR‐1298‐5p was downregulated. CircPKM2 knockdown effectively suppressed cell proliferation, migration, invasion and tube formation whereas induced apoptosis in vitro. CircPKM2 had a potential targeting site with miR‐1298‐5p and negatively regulated the expression of miR‐1298‐5p. MiR‐1298‐5p inhibitor reversed the effect of circPKM2 knockdown on the progression of NSCLC. CircPKM2 induced MTDH expression via sponging miR‐1298‐5p to promote the progression of NSCLC. MiR‐1298‐5p directly targeted MTDH, and the addition of MTDH partially attenuated the inhibition of miR‐1298‐5p on the progression of NSCLC. In addition, the downregulation of circPKM2 significantly slowed down the growth of xenograft tumors in vivo. Conclusion: Our findings demonstrated that circPKM2 mediated NSCLC progression via regulating miR‐1298‐5p/MTDH axis, providing a novel therapeutic target for NSCLC. [ABSTRACT FROM AUTHOR]

In this study, starch ferulate was synthesized employing a mechanoenzymatic method, specifically based on the twin screw extrusion technique and lipase catalysis. The research then primarily centered on optimizing process parameters and conducting structural analysis. Optimal conditions were determined to be 8.2% ferulic acid addition, 66 °C extrusion temperature, and 3.2% lipase (N435) addition. The enzyme-catalyzed time was 30 s. The degree of substitution for starch ferulate was quantified at 0.005581 under these specific conditions. The presence of C=O bonds in the synthesized starch ferulate proved that the synthesis process was efficient. Additionally, the crystal structure underwent reconstruction. Observations through Scanning Electron Microscopy (SEM) and Confocal Laser Scanning Microscopy (CLSM) demonstrated that the mechanoenzymatic method led to an augmentation in the specific surface area of starch molecules, thereby facilitating the exposure of active sites. This breakthrough underscores the vast potential of mechanoenzymatic techniques to revolutionize the rapid and sustainable synthesis of starch ferulate, marking a pioneering stride in ester synthesis. The insights garnered from this study transcend theory, offering a visionary roadmap for the development and real-world deployment of advanced modified starch esters. [ABSTRACT FROM AUTHOR]

Background: Studies have proven that the risk of acute kidney injury (AKI) increased in patients with malnutrition. Prognostic nutritional index (PNI) and geriatric nutritional risk index (GNRI) were general tools to predict the risk of mortality, but the prognostic value of them for in-hospital mortality among patients with AKI have not been validated yet. Herein, this study aims to explore the association between PNI and GNRI and 30-day mortality in patients with AKI. Methods: Demographic and clinical data of 863 adult patients with AKI were extracted from the Medical Information Mart for Intensive Care III (MIMIC-III) database in 2001–2012 in this retrospective cohort study. Univariate and multivariate Cox proportional regression analyses were used to explore the association between PNI and GNRI and 30-day mortality. The evaluation indexes were hazard ratios (HRs) and 95% confidence intervals (CIs). Subgroup analyses of age, Sequential Organ Failure Assessment (SOFA) score and Simplified Acute Physiology (SAPS-II) score were also performed. Results: Totally, 222 (26.71%) patients died within 30 days. After adjusting for covariates, PNI ≥ 28.5 [HR = 0.71, 95%CI: (0.51–0.98)] and GNRI ≥ 83.25 [HR = 0.63, 95%CI: (0.47–0.86)] were both associated with low risk of 30-day mortality. These relationships were also found in patients who aged ≥ 65 years old. Differently, high PNI level was associated with low risk of 30-day mortality among patients with SOFA score < 6 or SAPS-II score < 43, while high GNRI was associated with low risk of 30-day mortality among those who with SOFA score ≥ 6 or SAPS-II score ≥ 43 (all P < 0.05). Conclusion: PNI and GNRI may be potential predictors of 30-day mortality in patients with AKI. Whether the PNI is more recommended for patients with mild AKI, while GNRI for those with severe AKI is needed further exploration. [ABSTRACT FROM AUTHOR]

Although empirical evidence has confirmed the causal relationship between childhood maltreatment and depression, findings are inconsistent on the magnitude of the effect of age of exposure to childhood maltreatment on psychological development. This systematic review with meta-analysis aims to comprehensively synthesize the literature on the relationship between exposure age of maltreatment and depression and to quantitatively compare the magnitude of effect sizes across exposure age groups. Electronic databases and grey literature up to April 6th, 2022, were searched for English-language studies. Studies were included if they: 1) provided the information on exposure age; and 2) provided statistical indicators to examine the relationship between childhood maltreatment and depression. Fifty-eight articles met eligibility criteria and were included in meta-analyses. Subgroup analyses were conducted based on subtypes of maltreatment and measurements of depression. Any kind of maltreatment (correlation coefficient [r] = 0.17, 95% CI = 0.15–0.18), physical abuse (r =0.13, 95% CI = 0.10–0.15), sexual abuse (r = 0.18, 95% CI = 0.15–0.21), emotional abuse (r = 0.17, 95% CI=0.11–0.23), and neglect (r = 0.08, 95% CI=0.06–0.11) were associated with an increased risk of depression. Significant differential effects of maltreatment in depression were found across age groups of exposure to maltreatment (Q = 34.81, p < 0.001). Age of exposure in middle childhood (6–13 years) had the highest risk of depression, followed by late childhood (12–19 years) and early childhood (0–6 years). Implications of the findings provide robust evidence to support targeting victimized children of all ages and paying closer attention to those in middle childhood to effectively reduce the risk of depression.

Multicomponent metallacages can integrate the functions of their different building blocks to achieve synergetic effects for advanced applications. Herein, based on metal‐coordination‐driven self‐assembly, we report the preparation of a series of isoreticular tetraphenylethylene‐based metallacages, which are well characterized by multinuclear NMR, ESI‐TOF‐MS and single‐crystal X‐ray diffraction techniques. The suitable integration of photosensitizing tetraphenylethylene units as faces and Re catalytic complexes as the pillars into a single metallacage offers a high photocatalytic hydrogen production rate of 1707 μmol g−1 h−1, which is one of the highest values among reported metallacages. Femtosecond transient absorption and DFT calculations reveal that the metallacage can serve as a platform for the precise and organized arrangement of the two building blocks, enabling efficient and directional electron transfer for highly efficient photocatalytic performance. This study provides a general strategy to integrate multifunctional ligands into a certain metallacage to improve the efficiency of photocatalytic hydrogen production, which will guide the future design of metallacages towards photocatalysis.

Owing to their appealing three-dimensional structures and tunable photophysical properties, emissive metallacages have been widely applied in recognition and sensing, adsorption and separation, catalysis, etc. Recently, the application of emissive metallacages in biomedical fields has emerged as a hot research topic, because multiple biological functionalities can be facilely integrated into metallacage-based platforms to deliver different functions. In this review, the applications of emissive metallacages in bio-imaging, delivery and cancer theranostics are systematically summarized. The dilemmas and challenges of metallacage-based biomedical materials are also raised at the end of this review. We hope this review would provide some guidance for the construction of novel emissive metallacages with biological functions, and further advance the development of emissive metallacages as biomedical materials.

Background: The objective of this study was to investigate the association between white blood cell count to hemoglobin ratio (WHR) and risk of in-hospital mortality in patients with lung cancer. Methods: In this retrospective cohort study, the medical records of patients with lung cancer were retrieved from the electronic ICU (eICU) Collaborative Research Database between 2014 and 2015. The primary outcome was in-hospital mortality. The secondary outcome was the length of stay in intensive care unit (ICU). The cut-off value for the WHR was calculated by the X-tile software. The Cox model was applied to assess the association between WHR and in-hospital mortality among patients with lung cancer and the linear regression model was used to investigate the association between WHR and length of ICU stay. Subgroup analyses of age (< 65 years or > = 65 years), Acute Physiology and Chronic Health Evaluation (APACHE) score (< 59 or > = 59), gender, ventilation (yes or no), and vasopressor (yes or no) in patients with lung cancer were conducted. Results: Of the 768 included patients with lung cancer, 153 patients (19.92%) died in the hospital. The median total follow-up time was 6.88 (4.17, 11.23) days. The optimal cut-off value for WHR was 1.4. ICU lung cancer patients with WHR > = 1.4 had a significantly higher risk of in-hospital mortality [Hazard ratio: (HR): 1.65, 95% confidence interval (CI): 1.15 to 2.38, P = 0.007) and length of stay in ICU (HR: 0.63, 0.01, 95% CI: 1.24 to 0.045, P = 0.045). According to the subgroup analysis, WHR was found to be associated with in-hospital mortality in patients with higher APACHE score (HR: 1.60, 95% CI: 1.06 to 2.41, P = 0.024), in male patients (HR: 1.87, 95% CI: 1.15 to 3.04, P = 0.012), and in patients with the treatment of ventilation (HR: 2.33, 95% CI: 1.49 to 3.64, P < 0.001). Conclusion: This study suggests the association between WHR and risk of in-hospital mortality in patients with lung cancer and length of stay, which indicates the importance of attention to WHR for patients with lung cancer.

Li−S batteries with high energy density have the potential to become a viable alternative to Li‐ion batteries. However, Li−S batteries still face several challenges, including the shuttle effect, low conversion kinetics, and Li dendrite growth. Natural clay minerals with porous structures, abundant Lewis‐acid sites, high mechanical modulus, and versatile structural regulation show great potential for improving the performance of Li−S batteries. However, so far, relevant reviews focusing on the applications of natural clay minerals in Li−S batteries are still missing. To fill the gap, this review first presents an overview of the crystal structures of several natural clay minerals, including 1D (halloysites, attapulgites, and sepiolite), 2D (montmorillonite and vermiculite), and 3D (diatomite) structures, providing a theoretical basis for the application of natural clay minerals in Li−S batteries. Subsequently, research advancements in the natural clay‐based energy materials in Li−S batteries have been comprehensively reviewed. Finally, the perspectives concerning the development of natural clay minerals and their applications in Li−S batteries are provided. We hope this review can provide timely and comprehensive information on the correlation between the structure and function of natural clay minerals in Li−S batteries and offer guidance for material selection and structure optimization of natural clay‐based energy materials.

Bone defects (BDs), a prevalent clinically refractory orthopaedic disease, presently have no effective treatments. Mesenchymal stem cells (MSCs) can differentiate into osteoblasts and serve as potential seed cells for bone tissue engineering for BD treatment. However, the feasibility of using MSCs as seed cells for bone tissue engineering remains unclear. As a result, the critical issue of large‐scale cell‐scaffold preparation remains unresolved. In this study, we demonstrated for the first time that human embryonic stem cell‐derived MSCs, also known as immunity‐and‐matrix‐regulatory cells (IMRCs), could be inoculated into microcarriers to create osteogenic micro‐tissues appropriate for scalable production in 250 mL bioreactor. IMRCs were generally smaller than umbilical cord‐derived MSCs (UCMSCs) and could attach, migrate, proliferate and differentiate within the porous microcarriers, whereas UCMSCs could only attach to the surface of microcarriers. Osteogenic micro‐tissues generated from IMRCs‐seeded microcarriers significantly increased osteocalcin levels after 21 days of differentiation in a bioreactor. Furthermore, the expression levels of osteogenic biomarker genes/proteins such as alkaline phosphatase (ALP), osteocalcin (OCN), runt‐related transcription factor 2 (RUNX2), osteopontin (OPN) and osterix (OSX) were significantly higher than osteogenic micro‐tissues derived from UCMSCs‐seeded microcarriers. Our findings imply that IMRCs could potentially serve as seed cells for the scalable production of osteogenic micro‐tissues for BD treatment. [ABSTRACT FROM AUTHOR]
