The density shoulder represents a universal physical phenomenon that is closely related to the particle and energy transports occurring within the scrape-off layer (SOL) region of tokamak devices. A novel method has been developed to identify the density shoulder through the analysis of the bump structure in the time delay spectra from monostatic microwave reflectometry in EAST tokamak, obviating the need for density profile reconstruction. The density shoulder in EAST is characterized by a number of distinctive features. The density shoulder is mostly situated at a distance of 0–3 cm from the last closed flux surface, with a width of a few centimeters. No significant correlation is observed between its occurrence and the auxiliary heating or the confinement state. In the case of H-mode with quasi-coherent mode (QCM), a significant and positive correlation is observed between the density shoulder amplitude and QCM intensity. In the case of grassy-edge localized mode (ELM)-like H-mode, a density shoulder is also observed during the inter-ELM stage. Furthermore, as supersonic molecular beam injection (SMBI) deposits occur within the range of ρ = 0.9 ∼ 1, the density shoulder is also enhanced during the SMBI fueling process. Moreover, it appears that the neutral pressure has a more pronounced impact on the overall offset of the density profile than the strength of the density shoulder. These results collectively indicate that the outward particle transport from the pedestal to the SOL region plays a crucial role in the evolution of the density shoulder. [ABSTRACT FROM AUTHOR]

A 68-year-old man presented with subacute progressive numbness in his lower extremities and vertigo. Concurrently, he developed behavioral and cognitive changes. Initial examination demonstrated mild distal symmetric weakness in the lower extremities, allodynia in the feet, decreased proprioception at the ankles, and absent reflexes in the lower extremities. Electrodiagnostic studies showed a length-dependent, severe axonal sensorimotor polyneuropathy. He was hospitalized after experiencing daily falls and worsening executive dysfunction, during which time additional cognitive history and examination were completed. MRI brain revealed diffusion restriction in the bilateral caudate nuclei. Ultimately, CSF testing solidified the clinical diagnosis. This case highlights the differential diagnosis and diagnostic approach for rapidly progressive neuropathies associated with cognitive decline.

Recent studies have provided promising evidence that neuroimaging data can predict treatment outcomes for patients with major depressive disorder (MDD). As most of these studies had small sample sizes, a meta-analysis is warranted to identify the most robust findings and imaging modalities, and to compare predictive outcomes obtained in magnetic resonance imaging (MRI) and studies using clinical and demographic features. We conducted a literature search from database inception to July 22, 2023, to identify studies using pretreatment clinical or brain MRI features to predict treatment outcomes in patients with MDD. Two meta-analyses were conducted on clinical and MRI studies, respectively. The meta-regression was employed to explore the effects of covariates and compare the predictive performance between clinical and MRI groups, as well as across MRI modalities and intervention subgroups. Meta-analysis of 13 clinical studies yielded an area under the curve (AUC) of 0.73, while in 44 MRI studies, the AUC was 0.89. MRI studies showed a higher sensitivity than clinical studies (0.78 vs. 0.62, Z = 3.42, P = 0.001). In MRI studies, resting-state functional MRI (rsfMRI) exhibited a higher specificity than task-based fMRI (tbfMRI) (0.79 vs. 0.69, Z = -2.86, P = 0.004). No significant differences in predictive performance were found between structural and functional MRI, nor between different interventions. Of note, predictive MRI features for treatment outcomes in studies using antidepressants were predominantly located in the limbic and default mode networks, while studies of electroconvulsive therapy (ECT) were restricted mainly to the limbic network. Our findings suggest a promise for pretreatment brain MRI features to predict MDD treatment outcomes, outperforming clinical features. While tasks in tbfMRI studies differed, those studies overall had less predictive utility than rsfMRI data. Overlapping but distinct network-level measures predicted antidepressants and ECT outcomes. Future studies are needed to predict outcomes using multiple MRI features, and to clarify whether imaging features predict outcomes generally or differ depending on treatments., Competing Interests: Competing interests: Melissa P.

Objective: To evaluate the efficacy of non-pharmacological interventions in improving chemotherapy induced delayed nausea and vomiting symptoms using a network meta-analysis., Methods: Four Chinese databases (CNKI, Wanfang Data Knowledge Service Platform, VIP, Sinomed) and five English databases (PubMed, Cochrane Library, Embase, Web of Science, CINAHL) were searched from the establishment of the database to April 2024. A Bayesian network meta-analysis was performed on the response rate to the improvement of chemotherapy induced delayed nausea and vomiting, as well as improvement in KPS score, under different non-pharmacological interventions by using R 4.4.0 software and the GeMTC package., Results: A total of 58 RCTs 4081 patients were selected, involving 14 non-pharmacological interventions. The results of Meta-analysis showed that acupoint patch was identified as the most probable superior intervention in the improvement of chemotherapy induced delayed nausea and vomiting, and acupuncture was identified as the most probable superior intervention on the improvement of KPS scores., Conclusion: Non-pharmacological interventions can serve as an effective complementary approach to managing delayed chemotherapy-induced nausea and vomiting. In particular, acupoint application may be the optimal complementary therapy to mitigate the incidence of delayed nausea and vomiting, though more high-quality, large-scale evidence is required to conclusively demonstrate the efficacy of acupuncture in enhancing the quality of life for cancer patients., Competing Interests: Declaration of Competing Interest All authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 The Authors.

Background: Skin photoaging caused by ultraviolet rays (UVR) not only affects the appearance, but also leads to benign and malignant skin tumors. Vicenin-2, a bioflavonoid, exhibits anti-UVB properties, but its potential in preventing skin photoaging and the underlying mechanisms remain unclear. This study aims to elucidate the molecular mechanisms of Vicenin-2 in treating photoaging through network pharmacology, molecular docking, molecular dynamics simulation, and experimental validation., Methods: We utilized PubChem, Swiss Target Prediction, and Target Net databases to obtain the action targets of Vicenin-2. The Online Mendelian Inheritance in Man (OMIM), GeneCards, and Therapeutic Target Database (TTD) databases were employed to hunt for photoaging-related targets. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted via the Metascape database. Molecular docking and dynamics simulation methods were used for analyzing the binding sites and binding energies between Vicenin-2 and photoaging targets. Then, a photoaging mouse model and a Human foreskin fibroblast cells (HFF-1) model were created, the therapeutic effect and molecular mechanism of action of Vicenin-2 were validated by Hematoxylin and eosin (H&E), Masson staining and Elastica-Van Gieson (EVG) Staining, enzyme-linked immunosorbent assay (ELISA), Western blot (WB), Terminal Deoxynucleotidyl Transferase dUTP Nick End Labeling (TUNEL) Assay, Antioxidant enzyme activities and quantitative reverse transcription-polymerase chain reaction (qRT-PCR)., Result: The screening of chemical composition and targets indicated that 249 genetic targets of Vicenin-2 were related to photoaging. Bioinformatics analysis suggested that Matrix Metalloproteinases 9(MMP9), Glycogen Synthase Kinase 3(GSK3β), Heat Shock Protein 90 AA1(HSP90AA1) and Nuclear Factor kappa-B1(NF-κB1) might be potential targets for Vicenin-2 in photoaging therapy. Molecular docking and dynamics simulation further showed that Vicenin-2 had the best binding to GSK3β. Through experimental verification, it has been demonstrated that Vicenin-2 alleviate photoaging, acting on GSK3β to regulate the phosphatidylinositol 3- kinase/serine-threonione kinase (PI3K/Akt) pathways, by reducing inflammation and apoptosis., Conclusions: Vicenin-2 has anti-inflammatory and apoptosis-reducing effects through the action of multiple targets to relieve skin photoaging. Among them, GSK3β is the validated therapeutic target of Vicenin-2, which provides new ideas and clues for the development of photoaging therapy., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2025.

The environment monitoring of forest is vital for the ecosystem sustainable management, especially soil quality. Ancient Gleditsia sinensis is one of the most distributed ancient trees in Shaanxi. Comprehensive soil evaluate is important for the ancient tree protection. In this study, we selected the most distributed ancient tree Gleditsia sinensis and immature tree to compare the effect of growth stage to soil quality and soil bacteria. Most ancient tree soil nutrients were in good condition compared with immature tree. The bacterial community were composed with Proteobacteria (27.55%), Acidobacteriota (16.82%), Actinobacteriota (15.77%), Gemmatimonadota (6.82%), Crenarchaeota (4.61%), Bacteroidota (4.41%), Firmicutes (4.32%), Chloroflexi (4.28%), Planctomycetota (3.24%) and Verrucomicrobiota (3.04%). The level 2 ancient tree (300-400 years old) was different in bacterial community diversity. SOC and STN were important to level 2 (300-400 years old Gleditsia sinensis), and other levels were opposite. Our results suggested that the ancient tree management should not be lumped together., Competing Interests: Declarations.

Salmonella remains a major foodborne pathogen responsible for food poisoning and poses a serious threat to public health. This study has developed an edible antimicrobial film using bacteriophage (phage) SaTp-04, specifically designed to capture and eliminate Salmonella in food. Optimal film conditions were achieved using casein (CA) and sodium alginate (SA) as the matrix, glycerol as the plasticizer, and phage protector. The mechanical properties and phage encapsulation rate were used as response variables. The presence of phage SaTp-04 did not significantly alter the thickness, tensile strength, elongation at break, water vapor permeability, moisture content, or water solubility of the film. Furthermore, the Fourier Transform Infrared spectroscopy, X-ray diffraction, and microscopic morphology of the phage film were similar to those of the phage-free film. The phage titer in the film remained stable for up to five weeks at 4 °C. Phage release from the film in water followed a first-order kinetics model (y = 85.312 × (1-e -0.106x ), R 2  = 0.9687). The release amount and rate were lower at 4 °C on LB plate surfaces than at 25 °C. The phage film inhibited Salmonella growth on fresh chicken breast and carrots at 4 and 10 °C. The surface of chicken breast packaged with the phage film showed a reduction of approximately 6 log CFU/cm 2 in Salmonella compared to the control, while the carrot surface demonstrated a reduction in Salmonella to below the detection limit (10 CFU/cm 2 ) at 37 °C. These results confirm the feasibility of using phage SaTp-04 CA-SA edible films for food safety, providing a viable strategy for developing targeted capture packaging for foodborne pathogenic bacteria., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2025 Elsevier B.V.

Objective: To assess the performance of a standardized first-trimester ultrasound screening strategy for fetal congenital heart disease (CHD)., Methods: This was a large retrospective study involving 74 839 consecutive mixed-risk pregnancies (77 396 fetuses). Routine ultrasound scans at 11 + 0 to 13 + 6 weeks' gestation were performed in a single center from January 2015 to June 2023. All fetuses were examined using a predefined standardized ultrasound scanning strategy with adjustment of imaging parameters, which included assessment of the fetal heart. The ultrasound results (e.g. extracardiac congenital malformations), ultrasound markers (e.g. nuchal translucency thickening, reversed a-wave in the ductus venosus and tricuspid regurgitation), follow-up, genetic tests and diagnostic results were recorded and analyzed., Results: In total, there were 831 cases of CHD, with an incidence of 1.07% (831/77 396). In the first-trimester scan, 590 fetuses were diagnosed with CHD, but four were confirmed as normal in later examinations. In addition, 245 cases were missed. The detection rate was 70.52%, with a sensitivity, specificity, false-positive rate and false-negative rate of 70.52%, 99.99%, 0.01% and 29.48%, respectively. In fetuses with negative ultrasound markers and no extracardiac malformations, the detection rate of CHD was 45.79% (185/404). There were 281 cases that underwent karyotyping and chromosomal microarray (245 fetuses) or whole-exome sequencing (36 fetuses). In total, 38.79% (109/281) had a positive genetic test result. There were 273/831 CHD cases associated with extracardiac malformations. The abnormal image patterns and abnormal features of each view in the scanning strategy were summarized., Conclusions: Ultrasound screening for fetal CHD in the first trimester of pregnancy enables earlier prenatal diagnosis and consultation. The standardized ultrasound screening strategy used in this study had a high detection rate for fetal CHD in the first trimester. Our proposed fetal heart screening strategy shows promising effectiveness for early diagnosis of CHD and we recommend its use. It is important to note, however, that first-trimester ultrasound screening for fetal CHD should not replace fetal echocardiography in the second trimester. © 2025 International Society of Ultrasound in Obstetrics and Gynecology., (© 2025 International Society of Ultrasound in Obstetrics and Gynecology.)

Antibiotic resistance or tolerance of pathogens has become one of the global public crises. Finding new drug targets may open up a way of infection control. Phenazine pyocyanin (PYO) is an important virulence factor produced by the pathogen Pseudomonas aeruginosa. Here we show that a multidrug efflux pump repressor, MexL, acts as a transcriptional activator to enhance phenazines production via binding with a conserved DNA motif within the promoters of phenazines biosynthesis genes. Moreover, PYO functions as a self-regulating ligand of MexL for restricting its own production and the mexL knockout attenuates the virulence and antibiotics tolerance of P. aeruginosa. Based on the structure of MexL we resolve, we find two antimicrobials that can interact with MexL to reduce the PYO production and virulence of P. aeruginosa. Our in vivo studies suggest that the antimicrobials combination by using MexL-antagonists to reduce bacterial virulence and enhance the efficacy of common antibiotics can be an effective way to combat P. aeruginosa infection., Competing Interests: Competing interests: Two Chinese patent applications have been filed based on the results of this manuscript: No#202310675915.1 (L.M., Y.Z., H.Y., D.W.) and No#202411253300.0 (L.M., Y.Z., Y.Z1., D.L., Y.Z2., H.Y., D.W.).

Purpose: Individuals with convergence insufficiency (CI) encounter challenges in turning their eyes inward during near work. It is unclear how this relates to brain structural and functional alterations. This study aimed to explore the neural mechanism underlying CI using multimodal brain magnetic resonance imaging (MRI)., Methods: Thirty-four CI participants and 35 healthy controls (HC) were recruited, who underwent visual examinations and brain MRI scanning. Structural MRI data were analysed to calculate cortical thickness, volume and surface area. Fractional amplitude of low-frequency fluctuation (fALFF) and seed-based functional connectivity were obtained from resting-state functional MRI data. The brain structural and functional metrics were compared between the two groups followed by correlation analyses between clinical measurements and significant brain features., Results: Relative to HC, individuals with CI had lower grey matter volume (GMV) and surface area in the right frontal eye fields, parietal eye fields and left medial orbitofrontal cortex, higher GMV and surface area in the right middle frontal and inferior temporal gyri and higher fALFF of the left cerebellum and functional connection between bilateral cerebellums. GMV of the right middle frontal gyrus and fALFF in the left cerebellum were positively correlated with the near point of convergence in all participants., Conclusions: Lower structural metrics in the visual and oculomotor cortices and higher functional activity in the cerebellum may underpin convergence dysfunction and visual fatigue, while higher structural metrics in the right middle frontal and inferior temporal gyri reflect partial compensation for the visual and oculomotor cortex defects, thereby maintaining attention and parallax information processing. This study may enhance understanding of the neural mechanism of CI by revealing the impact of abnormal visual experiences of CI on the brain with disassociated structural and functional alterations in the vergence system., (© 2025 College of Optometrists.)

Amorphous phases hold great promise in diverse applications and are widely used by organisms as precursors to produce biominerals with complex morphologies and excellent properties. However, the stabilization and crystallization mechanisms of amorphous phases are not fully understood, especially in the presence of additives. Here, using amorphous calcium carbonate (ACC) as the model system, we systematically investigate the crystallization pathways of amorphous phases in the presence of poly(Aspartic acid) (pAsp) with various chain lengths. Results show that pure ACC transforms into a mixture of calcite and vaterite via the typical dissolution-recrystallization mechanism and 3 % of Asp monomer exhibits negligible effect. However, pAsp with a chain length of only 10 strongly inhibits the aggregation-induced formation of vaterite spheres while slightly delaying the growth of calcite via classical ion-by-ion attachment, thus kinetically favoring the formation of calcite. Moreover, the inhibition effect of calcite growth from solution ions becomes more prominent with the increase of pAsp chain length or concentration, which significantly improves the stability of the amorphous phase and leads to crystallization of spherical or elongated calcite via the nonclassical particle attachment mechanism after pseudomorphic transformation of ACC into vaterite nanoparticles. These results allow us to reach a more comprehensive understanding of the stabilization and crystallization mechanism of ACC in the presence of additives and provide guidelines for controlling the polymorph selection and morphology of crystals during the crystallization of amorphous precursors., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Phthalate acid esters (PAEs) and bisphenol A (BPA) are recognized as common endocrine disruptors associated with various adverse effects on human health. However, limitations in existing systematic studies, particularly in air detection, have raised concerns about potential health risks from inhalation exposure. In this study, PM 2.5 samples were collected in Dongying, a petrochemical city, from October 27 to December 6, 2021. The concentrations and compositions of PAEs and BPA in PM 2.5 were analyzed, and health risks associated with inhalation exposure were assessed. The hazard index (HI) and cancer risk (CR) were calculated according to EPA standard methods for both adults and children. The mean concentrations of PAEs and BPA were determined to be 1152 and 3.7 ng/m 3 , respectively. BPA concentrations were found to increase during heating, whereas PAE concentrations were observed to decrease slightly. Diisobutyl phthalate (DiBP), a major PAE, was reduced by approximately 20% during heating. However, 1,4-dimethylphthalazine (DMP) and bis(2-ethylhexyl) phthalate (DEHP) were observed to increase from 4.2 to 14% and from 5.9 to 11%, respectively. It is hypothesized that variations in the concentrations and compositions of airborne PAEs and BPA were influenced by district heating. An increase in the percentage of DEHP in PM 2.5 was noted on polluted days, likely influenced by saturated vapor pressure. The estimated daily intake (EDI) for children was calculated to be higher than that for adults, indicating that children were exposed to significantly greater potential risks, although overall risks were observed to be low. The results of this study provide essential baseline data, such as concentration, for the management and control of emerging pollutants like endocrine disruptors in the urban atmosphere., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Ovarian cancer (OC) is the third most common malignant tumor of women and is accompanied by an alteration of systemic metabolism. A liquid biopsy that captures and detects tumor-related biomarkers in body fluids has great potential for OC diagnosis. EVs, nanosized extracellular vesicles found in the blood, have been proposed as promising biomarkers for liquid biopsies. In this study we recruited 37 OC patients, 22 benign ovarian tumor (BE) patients, and 46 clinically healthy control patients (CON). Plasma EVs were purified from blood samples and sensitive thermal separation probe-based mass spectrometry analysis using a global untargeted metabolic profiling strategy was employed to characterize the metabolite fingerprints. Uniform manifold approximation and projection (UMAP) analysis demonstrated a distinct separation of EVs among the three groups. We screened for diagnostic biomarkers from plasma EV metabolites using seven machine learning algorithms, including artificial neural network (ANN), decision tree (DT), K nearest neighbor (KNN), logistics regression (LR), Naïve Bayes (NB), random forest (RF), and support vector machine (SVM). For the OC-CON comparison, the highest AUC values were found for RF (0.91), ANN (0.90) and NB (0.90), with the F1-scores of 0.88, 0.83, and 0.76 respectively. For the OC-BE comparison, SVM (0.94), RF (0.86), and KNN (0.86) gave the highest AUCs, with F1-scores of 0.80, 0.80, and 0.91 respectively. A total of 19 and 158 metabolic features exhibited significant differences (FC = 1.5, q < 0.01) in the OC vs BE and OC vs CON comparisons, respectively. Notably, the quantities of 9-octadecenamide and 1,4-methanobenzocyclodecene were significantly elevated, while maltol showed a significant reduction in the OC group compared to the BE group. When comparing the OC group to the CON group, the concentrations of 4-amino-furazan-3-carboxylic acid 2-hydroxy-4-methoxybenzaldehyde, N-phenylethyl, and 4-morpholineethanamine were significantly elevated, while the remaining metabolites, including hydrazine and pyridine sulfonamide, were reduced, in the OC group. The metabolites showing different abundancies are associated with cancer-related mutations, immune responses, and metabolic reprogramming. We demonstrate that the RF algorithm, combined with sensitive thermal separation probe-based mass spectrometry analysis of plasma EVs, can effectively identify OC patients with good accuracy. Thus, our study has shortlisted a set of potential biomarkers in plasma EVs, and the proposed approach could serve as a routine prescreening tool for ovarian cancer., Competing Interests: Declarations.

Sticker-type transparent antireflective film (STAF) is applied to perovskite solar cells (PSCs) to reduce the reflection and improve the light-trapping ability of PSCs. However, the development of STAF is hindered by many factors, such as expensive materials, low actual service life, unsatisfactory antireflective effect, and a lack of research on stability. This work proposes an ultraviolet (UV)-resistant enhanced sticker-type nanostructure acrylic resin antireflective film (SNAAF), which is applied to the incident surface of PSCs. SNAAF is prepared by using a cleverly designed two-step peeling transfer process. The average reflectance of the related device is reduced by 4.06% through the entire visible light spectrum, which also helps achieve the champion performance of the PSCs with STAF. The excellent antireflection performance increases power conversion efficiency (PCE) from 20.77% to 22.1% owing to the significantly enhanced short-circuit current density by 5.5% with the SNAAF. Additionally, the target device maintains nearly 80% of its initial PCE after 480 h of irradiation with UV light (365 nm), far exceeding the exposure levels in IEC 61215. Moreover, the designed SNAAF is applicable to large-area Cu(In, Ga)Se 2 (CIGS) solar cells (area: 225 cm 2 ), which develops a practical external engineering strategy for optimizing device performance for different types of commercial solar cells.

Ceramic materials have the merits of an adjustable dielectric constant, high strength, high temperature resistance, and oxidation resistance, and are thus being used as the protection matrix for carbon series, metal oxides, and other wave-absorbing materials at high temperatures. Here, progress on high-temperature-resistant wave-absorbing ceramic materials is introduced through the aspects of their composition and structure. In addition, metamaterials used for such purposes, which are mainly produced through 3D printing, are also highlighted. The pros and cons of high-temperature-resistant electromagnetic wave absorbers based on ceramic materials are systematically analyzed, and possible development directions are proposed. This work may assist in the design and manufacture of a new generation of radars, ships, and aircraft.

Ethnopharmacological Relevance: Reynoutria japonica has been utilized as a potential treatment for gastrointestinal disorders in Traditional Chinese Medicine (TCM). However, the efficacy and mechanism of its aqueous extracts on damp-heat ulcerative colitis (UC) remains unclear., Aim of the Study: Investigating the modulating effect of aqueous extracts of Reynoutria japonica (AERJ) on gut microbiota and fecal metabolisms in mice with damp-heat UC., Methods: UPLC-Q-TOF-MS was used for the compositional characterization of the AERJ. BALB/c mice were used as a model for establishing damp-heat UC. Hematoxylin-eosin (HE) staining and immunohistochemistry (IHC) method were conducted to observe the pathological changes in the colon. Enzyme-linked immunosorbent assay (ELISA) was used for quantitative analysis of relevant physiological indicators. 16 S rRNA gene sequencing was employed to detect changes in gut microbiota in mice. In addition, metabolomics analysis was performed on mice feces. Finally, the aforementioned indicators underwent correlation analysis., Results: Seven components within the AERJ were qualitatively identified by chromatographic analysis. The AERJ alleviated the symptoms in damp-heat UC mice, suppressed the expression of inflammatory factors, attenuated mucosal damage, improved water-fluid metabolism, and regulated the gut microbiota composition. Differential metabolites in feces were mainly enriched in the amino acid metabolic pathway, and AERJ was able to upregulate the expression levels of short chain fatty acids (SCFAs). Meanwhile, the present study found that physiological indicators were significantly correlated with both the gut microbiota and SCFAs., Conclusion: AERJ showed significant therapeutic effects on damp-heat UC mice, and its mechanism of action may be related to altering the composition of gut microbiota, regulating amino acid metabolism and the content of SCFAs and thus restoring the mucosal integrity and inflammatory response., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Gastric cancer (GC) is a frequently diagnosed malignant tumor in clinical settings; however, the mechanisms underlying its tumorigenesis remain inadequately understood. In this study, we identified significantly elevated expression levels of AKR1B1 in GC tissues through quantitative polymerase chain reaction (qPCR) and western blotting assays. Furthermore, a negative correlation was established between patient survival probability and AKR1B1 expression levels. Functionally, our experiments, including colony formation, transwell migration, and xenograft assays, demonstrated that the depletion of AKR1B1 inhibited the proliferation and progression of GC cells both in vivo and in vitro. Additionally, the assessment of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and mitochondrial morphology confirmed that AKR1B1 depletion induces ferroptosis. Mechanistically, we found that AKR1B1 interacts with STAT3, which subsequently activates SLC7A11. Notably, the ferroptosis induced by AKR1B1 depletion could be reversed by the overexpression of SLC7A11, thereby substantiating these interactions. In conclusion, our findings identify AKR1B1 as a novel oncogene in GC and elucidate the mechanism involving the AKR1B1-STAT3-SLC7A11 pathway and ferroptosis, providing new insights for potential therapeutic strategies in the treatment of GC., (© 2025 International Federation for Cell Biology.)

Lattice distortion and disorder in the chemical environment of magnetic atoms within high-entropy compounds present intriguing issues in the modulation of magnetic functional compounds. However, the complexity inherent in high-entropy disordered systems has resulted in a relative scarcity of comprehensive investigations exploring the magnetic functional mechanisms of these alloys. Herein, we investigate the magnetocaloric effect (MCE) of the high-entropy intermetallic compound Gd 0.2 Tb 0.2 Dy 0.2 Ho 0.2 Er 0.2 Co 2 . Notably, the operating temperature range of the MCE broadens by an order of magnitude from 9 to 83 K while maintaining the refrigeration capacity compared to ErCo 2 . Atomic-scale microstructure analysis and atomic pair distribution function measurements reveal that lattice distortion stabilizes the cubic structure and induces disorder in the chemical environment of magnetic atoms. First-principles calculations point out that the enhanced average correlation energy raises the Curie temperature. The random distribution of elements across these sites induces local magnetic disorder around magnetic atoms with lower correlation energy, broadening the operating temperature range of MCE. This study not only significantly advances the understanding of the magnetic behavior of high-entropy alloys but also promotes the research progress of high-entropy functional compounds.

Glioblastoma multiforme (GBM) is the most malignant brain tumor, with radiotherapy frequently employed following surgical resection. However, conventional radiation therapies often yield suboptimal results. This study investigated the effects of X-ray and carbon ion irradiation on the glioblastoma cell line U251 to assess the distinctive advantages of carbon ion treatment and explore mechanisms for overcoming radiation resistance. The findings indicated that carbon ion irradiation more effectively inhibited colony formation and induced more severe apoptosis and cell cycle disorder in U251 cells. Immunofluorescence assays revealed larger and more abundant ϒ-H2AX and 53BP1 foci in the carbon ion irradiation group. Western blot analysis demonstrated that carbon ion-induced DNA damage repair involved a complex array of pathways, with the RAD51-mediated homologous recombination (HR) pathway being predominant, while the Rad23B-mediated nucleotide excision repair (NER) pathway and XRCC1-mediated base excision repair (BER) were more relevant in response to X-ray irradiation. These results suggest that carbon ion irradiation may overcome radioresistance by inducing more complex DNA damage and apoptosis, thus providing insights for targeting new strategies in combining gene therapy with radiotherapy., Competing Interests: Declarations.

Objective: To analyze the molecular genetic spectrum of children with acute myeloid leukemia (AML), and explore its correlation with clinical characteristics and prognosis., Methods: The clinical and molecular genetic data of 116 children with newly diagnosed AML in Wuhan Children's Hospital from September 2015 to August 2022 were retrospectively analyzed. The Fisher's exact test was used to analyze the correlation of gene mutations with clinical features, and Kaplan-Meier curve was used to analyze the influences of gene mutations on the prognosis., Results: NRAS (22%), KRAS (14.9%), and KIT (14.7%) mutations were the most common genetic abnormalities in 116 children with AML. Children with KIT, CEBPA and GATA2 mutations showed a higher median onset-age than those without mutations (all P < 0.05). Children with FLT3-ITD mutation exhibited a higher white blood cell count at initial diagnosis compared to those without mutations ( P < 0.05). Children with ASXL2 mutation had lower platelet count and hemoglobin at initial diagnosis than those without mutations (both P < 0.05). KIT mutations were often co-occurred with t(8;21)(q22;q22). There was no significant relationship between gene mutation and minimal residual disease (MRD) remission rate after the first and second induction therapy ( P >0.05). KIT and NRAS mutations were not associated with prognosis significantly ( P >0.05). The overall survival (OS) rates of children with CEBPA and FLT3-ITD mutations were superior to those without mutations, but the differences were not statistically significant ( P >0.05). The 3-year OS rate of 61 children treated by allogeneic hematopoietic stem cell transplantation was 89.8%, which was significantly higher than 55.2% of those only treated by chemotherapy ( P < 0.001)., Conclusions: Gene mutations are common in children with AML, and next-generation sequencing can significantly improve the detection rate of gene mutations, which can guide the risk stratification therapy. In addition, FLT3-ITD and KIT mutations may no longer be poor prognostic factors.

Acid whey, a dairy byproduct with low pH and high organic content, presents disposal challenges but also potential for resource recovery. In this study, chitosan gel was synthesized and evaluated for turbidity reduction of acid whey. Machine learning (ML) models were employed to predict and optimize the pretreatment process, with the Random Forest algorithm achieving a prediction accuracy of 0.78. Using the Simulated Annealing algorithm, optimal conditions were identified, applying a 2.2 % chitosan solution gel at a dosage of 24 g/L to acid whey at pH 4.6 for 12 h, achieving a 91 % turbidity reduction, a significant improvement over the 71 % obtained prior to optimization. Validation experiments confirmed its effectiveness in predicting and optimizing the pretreatment process. These findings highlight the feasibility of ML in optimizing chitosan pretreatment and demonstrate chitosan gel as a cost-effective, efficient option for acid whey, with potential to enhance resource recovery in the dairy industry., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Ethnopharmacological Relevance: Both clinical and animal studies have demonstrated that ginseng has curative effects on fatigue. Our previous study found that water extracts of ginseng (WEG) could significantly mitigate exercise-induced fatigue (EF). Notably, polysaccharides (GP) and small molecules (GS, mainly ginsenosides) coexist in WEG. Whether and how GP and GS contribute to the anti-EF effects of WEG remains unknown., Aim of the Study: To evaluate the contribution of GP and GS to the anti-EF effects of WEG and clarify the potential gut microbiota-mediated mechanisms., Materials and Methods: Firstly, the anti-EF effects of WEG, GP and GS were comparatively investigated by determining fatigue phenotypes (energy metabolism and oxidative stress parameters), gut microbiota composition as well as exogenous and endogenous metabolites in EF modeling rats. Then, the gut microbiota mediated mechanisms were verified by antibiotics (ABX) intervention and fecal microbial transplantation (FMT)., Results: GP, GS and WEG each exhibited distinct anti-EF effects in differentially improving EF-induced energy metabolism abnormality and oxidative stress, reshaping gut microbiota composition, and elevating systemic metabolites. Notably, WEG showed stronger anti-EF effects than both GP and GS, characterized by better alleviation of disturbances in energy metabolism (e.g. Glc) and oxidative stress parameters (e.g. SOD), regulation of gut microbiota homeostasis (e.g. enriching the genus Coprococcus and species Collinsella provencensis etc.), as well as increases in exogenous secondary ginsenosides (e.g. 20(S)-Rg 3 , 20(R)-Rg 3 , CK), endogenous bile acids (BAs) (e.g. CA, DCA, LCA), and short chain fatty acids (SCFAs) (e.g. butyric acid). The stronger anti-EF effects of WEG compared to GP and GS could be abolished by ABX intervention, and transferred by FMT., Conclusion: GP and GS could collectively contribute to the anti-EF effects of WEG through integrated actions. Gut microbiota mediate the integrated anti-EF effects of GP and GS in WEG, potentially by regulating the levels of exogenous bioactive secondary ginsenosides, as well as endogenous BAs and SCFAs, thereby alleviating fatigue-related energy metabolic abnormalities and oxidative stress., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Bisphenols (BPs) are ubiquitous environmental endocrine disruptors that cause various human health hazards and pollute water, soil, and the atmosphere to varying degrees. Although various studies have investigated the pollution characteristics and health hazards of BPs in different media, a systematic review of BPs in the broader environmental context is still lacking. This study highlights the pollution characteristics, detection methods, and risk assessment status of BPs by combining relevant studies from both domestic and international sources, and their environmental distribution characteristics are summarized. The results show that BP pollution is a widespread and complex global phenomenon. Bisphenol A (BPA) remains the predominant component of BPs, which can damage the nervous and reproductive systems. At present, high-performance liquid chromatography-tandem mass spectrometry, high-performance liquid chromatography, and liquid chromatography-tandem mass spectrometry are the main detection methods used for BPs. BPs can also damage the reproductive system, leading to germ cell apoptosis and ovarian damage. Future research should focus on expanding the BP testing repertoire, advancing rapid detection techniques, elucidating toxic mechanisms, conducting comprehensive safety assessments, and developing systematic health risk assessment methods. These efforts will provide a scientific foundation for preventing and controlling emerging pollutants.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a notably common complication in pediatrics, with an incidence rate ranging from 15 to 64%. This rate is significantly higher than that observed in adults. Currently, there is a lack of substantial evidence regarding the association between intraoperative blood pressure variability (BPV) during cardiac surgery with cardiopulmonary bypass (CPB) and the development of AKI in pediatric patients., Methods: This retrospective observational study encompassed children aged 0-7 years undergoing cardiac surgery with CPB. Intraoperative BPV was calculated using coefficients of variation (CVs) and the area under the curve (AUC). Univariate and multivariate analyses were employed to identify risk factors associated with CSA-AKI., Results: Among 570 patients (median age 1 year) reviewed, 36.1% developed CSA-AKI (68.9% risk stage, 22.8% injury stage, and 8.3% failure stage). After adjusting for other variables, male gender (OR = 2.044, 95% CI 1.297-3.222, P = 0.002), congenital heart surgery risk assessment grade (RACHS-1) classification ≥ 3 (OR = 0.510, 95% CI 0.307-0.846, P = 0.009), longer CPB time (OR = 1.022, 95% CI 1.007-1.037, P = 0.004) and higher peak value of intraoperative vasoactive inotropic score (VIS) (OR = 1.072, 95% CI 1.026-1.119, P = 0.002) were identified as independent risk factors for CSA-AKI. ± 30% AUCm was different in univariate analysis (P = 0.014), however, not statistically different in multifactor analysis (P = 0.610)., Conclusion: Greater BPV, specifically MAP variations exceeding 30% AUC during CPB, may be a potential risk factor for CSA-AKI in pediatric patients. Further large sample clinical studies are warranted to analyze the correlation between BPV and CSA-AKI., Competing Interests: Declarations.

As one of China's most treasured traditional flowers, Rhododendron Subgen. Hymenanthes is renowned worldwide for its evergreen foliage, vibrant flowers, and significant ornamental, landscaping, and economic value. However, climate change poses a serious threat to its future, leading to population declines and endangerment of some species. Despite the ecological and economic importance of Rhododendron Subgen. Hymenanthes, the future distribution of suitable habitats and the most effective strategies for its conservation and utilization remain unclear. This study employs the MaxEnt model, which is well-known for its reliability in predicting species distribution under changing environmental conditions, to predict the potential global distribution of nine species of Rhododendron Subgen. Hymenanthes. The goal is to provide a solid foundation for their conservation, cultivation management, and breeding. The results indicate that, under future climate scenarios, suitable habitat areas for four species (R. irroratum, R. agastum, R. decorum, and R. arboreum) will significantly decrease, while suitable habitats for the remaining five species (R. delavayi, R. fortunei, R. calophytum, R. simiarum, and R. wardii) will experience slight expansion. Temperature and precipitation are identified as key environmental factors influencing the growth and distribution of these species, affecting their ability to colonize new regions. The migration direction of the expanding regions for all nine species is consistent, with their centroids shifting towards the northwest. These findings provide critical insights for developing targeted conservation strategies, including identifying potential refugia and prioritizing conservation areas under future climate conditions., Competing Interests: Declarations.

To examine the therapeutic effectiveness and safety of traditional Chinese medicine in conjunction with PD-1/PD-L1 inhibitors for nourishing yin and replenishing qi in patients with non-small cell lung cancer. A systematic search was conducted across seven electronic databases, namely PubMed, Cochrane Library, Excerpt Medica Database, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and Wan-fang Database, to identify eligible studies from 2,000 to 2,023. This study includes a total of 14 randomized controlled clinical trials, with 514 patients in the TCM combo therapy group and 506 patients in the control group. The meta-analysis demonstrated the efficacy of combining TCM in oral and injectable forms with PD-1/PD-L1 inhibitors, with or without chemotherapy, in enhancing objective response rate, disease control rate, and quality of life in patients with NSCLC. Additionally, this combination therapy improved the proportion of CD3 + T cells and CD4 + T cells, as well as the ratio of CD4+/CD8 + T lymphocytes. The group receiving combined treatment with TCM successfully decreased the expression of the tumor marker CYFRA21-1. The group receiving combination therapy with TCM decreased the probability of experiencing adverse effects such as nausea, leukopenia, thrombocytopenia, and exhaustion in patients. Additionally, this treatment did not place additional strain on the liver and kidney functions. The integration of TCM techniques that nourishing yin and replenishing qi with PD-1/PD-L1 inhibitors greatly enhances the clinical effectiveness and safety of treating NSCLC. Additionally, the combination of Chinese and Western drugs improves the efficacy of neoadjuvant chemotherapy in NSCLC patients., (© The Author(s) 2025. Published by Oxford University Press.)

Objectives: This study aimed to systematically incorporate the post-traumatic growth experience of breast cancer patients and furnish insights for the formulation of targeted psychological care measures., Methods: The search period we were ranged from establishing the database to February 2024. We systematically searched four Chinese databases and seven English databases. The focus was on collecting qualitative research literature regarding the post-traumatic growth experience of breast cancer patients. Literature was screened and analyzed using Endnote20 software.

Background: Maintaining effective disease control in patients with inflammatory bowel disease (IBD) is both a significant goal and challenge. Drawing on the Common-Sense Model of Self-Regulation (CSM) and related research, this study investigates how IBD activity status influences disease control through both direct and indirect pathways., Methods: A cross-sectional survey was conducted among 310 IBD patients who attended a tertiary general hospital, the leader of the IBD Alliance Group in Chongqing City, between March and August 2024. Structural equation modeling (SEM) was utilized to assess the role and magnitude of various influencing factor pathways. Relying on AMOS26 software, the path effects and magnitude of various factors in the disease control process were analyzed using structural equation modeling (SEM) to test hypothetical models., Results: A total of 306 valid questionnaires were collected, with a mean IBD-control score of 12.14 ± 3.665. There was a negative link between disease activity and IBD-control (P < 0.01) and a positive correlation between chronic illness management self-efficacy, IBD self-management behavior, and IBD-control (P < 0.01). Path analysis showed that IBD activity negatively predicted IBD control (β = -0.715, P = 0.01). Chronic disease management self-efficacy partially mediated this relationship (β = -0.071, P = 0.012). A significant chain-mediated pathway was identified, where IBD activity affected IBD control via self-efficacy guided by self-management behavior (β = -0.025, P = 0.007). However, the pathway where IBD activity influenced control through self-efficacy and subsequently self-management behavior showed only marginal significance (P = 0.074)., Conclusion: Effective self-management behaviors improve IBD control. High disease activity may reduce chronic disease management self-efficacy, impairing IBD control. Positive feedback loops involving self-management behaviors and enhanced self-efficacy are crucial for better disease control, as patients who perceive positive outcomes are more motivated to maintain these behaviors., Competing Interests: Declarations. Ethics approval and consent to participate: The study was approved by the Ethics Committee of the Affiliated Hospital of Chongqing University (Approval No. KY S2023-067–01) and conducted in accordance with the principles outlined in the Declaration of Helsinki.

Ferromagnetic insulators are receiving ever-increasing research activities driven not only by the unique advantage of low power loss during spin-wave-based information processing but also by the potential to construct next-generation spintronic devices. However, either the exceedingly rare candidates or the low Curie temperature far below room temperature greatly hinder their practical application. Here, through the modulation of a novel three-dimensional (3D) tensile strain, a room-temperature ferromagnetic insulating state with a Curie temperature as high as 594 K is achieved in self-assembled LaCoO&#95;{3}:MgO nanocomposite thin films. Atomically resolved electron microscopy quantifications identify the 3D strain state of the thin film, where the +2.6% out-of-plane and +2.1% in-plane tensile strains are attributed to the interphase mismatch between the LaCoO&#95;{3} and MgO building blocks and epitaxial constraint, respectively. Combined with the assessment of electronic states and theoretical analysis, we correlate the strain state with the resulting ferromagnetic insulating property and clarify the underlying mechanisms, by which the emergent strain states break the degeneracy of crystal-field splitting and tailor the on-site Coulomb interactions and spin configuration. These findings underscore the efficacy of a three-dimensional strain strategy in engineering the long-desired high-temperature ferromagnetic insulators via the manipulation of strong spin-lattice coupling, providing a promising approach for the exploitation of exotic functionalities in correlated oxides.

The initial interzone cells for synovial joints originate from chondrocytes, but such critical transition is minimally understood. With single-cell RNA sequencing (scRNA-seq) of murine embryonic knee joint primordia, we discovered that heightened expression of glycolysis genes characterized developing interzone cells when compared to flanking chondrocytes. Conditional deletion of the glucose transporters Glut1 and/or Glut3 , in either the incipient pre-skeletal mesenchyme with Prx1Cre or in chondrocytes with Col2Cre , disrupted interzone formation dose-dependently. In contrast, deletion of Glut1 / 3 in established interzone cells with Gdf5Cre did not have similar severe disruption of joint development. scRNA-seq revealed that Glut1/3 deletion by Prx1Cre impeded Tgfβ signaling in the developing interzone cells. Direct elimination of Tgfβ signaling with Prx1Cre partially phenocopied the deletion of Glut1/3 in impairing interzone formation. Tgfβ stimulated glycolysis in chondrocytes via activation of mTOR and Hif1α in vitro. The data support that the essential conversion of chondrocytes to interzone cells requires a transient elevation of glycolysis partly dependent on Tgfβ signaling.

Backgrounds: Collagen type I alpha 1 chain (COL1A1) is a key protein encoding fibrillar collagen, playing a crucial role in the tumor microenvironment (TME) due to its complex functions and close association with tumor invasiveness. This has made COL1A1 a focal point in cancer biology research. However, studies investigating the relationship between COL1A1 expression levels and clinical characteristics of ovarian cancer (OC) remain limited., Methods: This study integrated resources from publicly available online databases and immunohistochemistry (IHC) techniques to analyze and validate COL1A1 expression in OC tissues, and evaluated its potential association with clinical features in OC patients. The prognostic value of COL1A1 was assessed using Kaplan-Meier (KM) survival curve analysis. The TIMER and TISIDB databases to explore the potential relationship between COL1A1 expression and immune microenvironment in OC tissues. The LinkedOmics and INPUT2 databases were used to analyze differential gene expression in OC, This was followed by enrichment analysis using the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) annotations to identify and predict potential signaling pathways associated with COL1A1., Results: Our study demonstrated that COL1A1 expression was significantly elevated in OC tissues compared to normal ovarian tissues. This elevated expression was closely associated with tumor metastasis, poor prognosis, and advanced pathological stages in OC patients. Moreover, COL1A1 expression showed a significant correlation with immune cell infiltration and the expression of immune-related genes within the TME.Further analyses revealed that COL1A1 and its co-expressed genes were primarily enriched in key signaling pathways involved in OC invasion, metastasis, and angiogenesis, indicating its potential role in driving OC progression., Conclusions: Our study found that upregulation of COL1A1 expression is significantly associated with lymph node metastasis of OC and can affect the immune microenvironment. Based on this, COL1A1 could serve as a promising biomarker for OC prognosis and provide a new perspective for the development of potential immunotherapies for patients with OC., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2025 Xiao, Long, Yu, Wu, Nie, Ren, Li, Wang, Yu, Wang and Wang.)

The pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD) remains unclear due to the complexity of its etiology. The emerging field of the epitranscriptome has shown significant promise in advancing the understanding of disease pathogenesis and developing new therapeutic approaches. Recent research has demonstrated that N4-acetylcytosine (ac4C), an RNA modification within the epitranscriptome, is implicated in progression of various diseases. However, the role of ac4C modification in MASLD remains unexplored. Herein, we performed acRIP-ac4c-seq and RNA-seq analysis in free fatty acids-induced MASLD model cells, identifying 2128 differentially acetylated ac4C sites, with 1031 hyperacetylated and 1097 hypoacetylated peaks in MASLD model cells. Functional enrichments analysis showed that ac4C differentially modified genes were significantly involved in processes related to MASLD, such as nuclear transport and MAP kinase (MAPK) signaling pathway. We also identified 341 differentially expressed genes (DEGs), including 61 lncRNAs and 280 mRNAs, between control and MASLD model cells. Bioinformatics analysis showed that DEGs were significantly enriched in long-chain fatty acid biosynthetic process. Notably, 118 genes exhibited significant changes in both ac4C modification and expression levels in MASLD model cells. Among these proteins, JUN, caveolin-1 (CAV1), fatty acid synthase (FASN), and heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) were identified as core proteins through protein-protein interaction (PPI) network analysis using cytoscape software. Collectively, our findings establish a positive correlation between ac4C modification and the pathogenesis of MASLD and suggest that ac4C modification may serve as a therapeutic target for MASLD., Competing Interests: Declarations.

Iron alloys, including steels and magnetic functional materials, are widely used in capital construction, manufacturing, electromagnetic technology, etc. However, they face the long-standing challenge of high coefficient of thermal expansion (CTE), limiting the applications in high-precision fields. This work proposes a strategy involving the in-situ formation of a nano-scale lamellar/labyrinthine negative thermal expansion (NTE) phase within the iron matrix to tackle this problem. For example, a model alloy, Fe-Zr10-Nb6, was synthesized and its CTE is reduced to approximately half of the iron matrix. Meanwhile, the alloy possesses a strength-plasticity combination of 1.5 GPa (compressive strength) and 17.5% (ultimate strain), which outperforms other low thermal expansion (LTE) metallic materials. The magnetovolume effect of the NTE phase is deemed to counteract the positive thermal expansion in iron. The high stress-carrying hard NTE phase and the tough matrix synergistically contribute to the high mechanical properties. The interaction between the slip of lamellar microstructure and the slip-hindering of labyrinthine microstructure further enhances the strength-plasticity combination. This work shows the promise of offering a method to produce LTE iron alloys with high mechanical properties., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

To unlock the potential of strains for further enhancing the aromatic complexity of kiwifruit wines while avoiding undesirable flavors, indigenous non-Saccharomyces yeast extracellular extract treatment for fermentation was established. The extracellular extract from Zygosaccharomyces rouxii, Pichia kudriavzevii, and Meyerozyma guilliermondii were prepared and supplemented individually or in pairs to the kiwifruit wine fermentation system. Subsequently, the changes in physicochemical properties, antioxidants, and volatile characteristics of kiwifruit wines produced by different protocols were comprehensively evaluated, and the major aroma descriptors affecting sensory acceptability were analyzed by sensory evaluation and partial least squares regression. The results showed that extracellular extract treatment significantly improved the organic acids and monomeric phenols content, antioxidant capacity, and volatiles of kiwifruit wines. Compared to Sc, the increase in esters and alcohols, along with the decrease in aldehydes and acids in Pk-Zr and Mg-Zr, enhanced the aromatic complexity while reduce grassy and fungal flavors, resulting in higher sensory acceptability., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

Aims: The purpose of this study was to explore the dose-response relationship between the age at diagnosis of cardiovascular metabolic multimorbidity and cognitive impairment among middle-aged and older adults in China., Methods: This is a secondary study using the China Health Retirement Longitudinal Study 2018(CHARLS 2018). The study included 1338 middle-aged and older adults. The middle-aged and older adults is defined as having cardiovascular metabolic multimorbidity if he or she has two or more of the five diseases (hypertension, diabetes, dyslipidemia, stroke, and heart disease). We measured cognitive functions by evaluating situational memory capacity and mental status. The total cognitive function score ranges from 0 to 31. Participants defined cognitive impairment as a function of subject educational level: illiteracy<17, primary school<20, junior high school and above<24. Restrictive cubic splines were used to examine the shape of the association between the age at diagnosis of cardiovascular metabolic multimorbidity and cognitive impairment., Results: The mean age was 67.72±9.96 years, with 52.0 % being female. Of the total sample, 79.1 % were cognitive impairment. When all covariates were adjusted, our study showed that the later the age of diagnosis of cardiovascular metabolic multimorbidity in middle-aged and older adults, the more cognitive impairment is exacerbated., Conclusion: The later age of diagnosis of CMM in middle-aged and older adults, the higher the risk of cognitive impairment. This suggests that nurses should promptly emphasize the relationship between CMM and cognitive impairment to their patients in their daily practice and encourage patients to be screened for CMM as early as possible., Competing Interests: Declaration of competing interest No conflict of interest exists in the submission of this manuscript, and the manuscript is approved by all authors for publication., (Copyright © 2024 Elsevier Inc.

Sevoflurane (Sev) is a widely applied anesthetic in clinical practice; however, it could induce neurotoxicity and lead to postoperative cognitive dysfunction (POCD). This study aimed to investigate the role and underlying mechanism of circHOMER1 in Sev-induced neurotoxicity and POCD. Sev treated mouse hippocampal neuronal HT22 cells and SD rats. RT-qPCR was used to detect the levels of circHOMER1 and miR-217. ELISA was employed to measure the levels of inflammatory factors IL-6, IL-1β, and TNF-α. Commercially available kits assessed the concentration of MDA and measured the activities LDH and SOD. The CCK-8 assay assessed cell viability. Flow cytometry analyzed cell apoptosis. The Morris water maze test evaluated the learning and cognitive abilities of the rats. Dual luciferase reporter assays and RIP experiments validated the targeted binding of circHOMER1 to miR-217. Sev treatment significantly reduces cell viability, increases apoptosis, stimulates inflammatory responses and oxidative stress, and induces learning and memory impairments in SD rats. Following exposure to Sev, the expression of circHOMER1 is markedly decreased, while overexpression of circHOMER1 can alleviate Sev-induced neuroinflammation, oxidative stress, and learning and memory deficits in rats. CircHOMER1 targets miR-217, and transfection of miR-217 antagonizes the neuroprotective effects of circHOMER1. This study demonstrated that circHOMER1 negatively regulated miR-217, thereby inhibiting Sev-induced neurotoxicity and learning and memory disorders., (© 2025 Wiley Periodicals LLC.)

Metabolic disorders and gut microbiota dysbiosis contribute to the complicated pathology of chronic obstructive pulmonary disease (COPD). Qi-Huo-Yi-Fei formula (QHYFF) is a Chinese medicine prescription for COPD treatment and has showed beneficial clinical effects, but the underlying mechanism remains elusive. This study integrated metabolomics and gut microbiota analysis to explore potential mechanism of QHYFF against COPD. The therapeutic effects of QHYFF were evaluated using a murine model of COPD induced by cigarette smoke and lipopolysaccharide. QHYFF effectively improved pulmonary function, suppressed inflammation, and relieved lung pathological changes. Serum and urine metabolomics analysis identified 19 differential metabolites, such as L-tyrosine, epinephrine, dopamine, hypotaurine, citric acid, L-tryptophan and indoleacrylic acid, involving tyrosine metabolism, taurine and hypotaurine metabolism, citrate cycle and tryptophan metabolism. QHYFF also enriched Bifidobacterium, Blautia, Faecalibaculum and Parasutterella. Moreover, Spearman's correlation analysis showed that discriminative metabolites and bacteria were closely correlated with efficacy indices. The findings indicated that QHYFF could be an effective therapeutic measure against COPD by regulating metabolism and gut microbiota., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Hopfield neural networks (HNNs) promise broad applications in areas such as combinatorial optimization, memory storage, and pattern recognition. Among various implementations, optical HNNs are particularly interesting because they can take advantage of fast optical matrix-vector multiplications. Yet their studies so far have mostly been on the theoretical side, and the effects of optical imperfections and robustness against memory errors remain to be quantified. Here we demonstrate an optical HNN in a simple experimental setup using a spatial light modulator with 100 neurons. It successfully stores and retrieves 13 patterns, which approaches the critical capacity limit of α c  = 0.138. It is robust against random phase flipping errors of the stored patterns, achieving high fidelity in recognizing and storing patterns even when 30% pixels are randomly flipped. Our results highlight the potential of optical HNNs in practical applications such as real-time image processing for autonomous driving, enhanced AI with fast memory retrieval, and other scenarios requiring efficient data processing.

Background and Objective: Radiofrequency ablation (RFA) is an emerging treatment of lung cancer, yet it is accompanied by certain safety concerns and operational limitations. This first multi-centre, large-scale clinical trial aimed to investigate the technical performance, efficacy and safety of an innovative transbronchial RFA system for lung tumours., Methods: The study enrolled patients with malignant lung tumours who underwent transbronchial RFA using an automatic saline microperfusion system between January 2021 and December 2021 across 16 medical centres. The primary endpoint was the complete ablation rate. The performance and safety of the technique, along with the 1-year survival rates, were evaluated., Results: This study included 126 patients (age range: 23-85 years) with 130 lung tumours (mean size: 18.77 × 14.15 mm) who had undergone 153 transbronchial RFA sessions, with a technique success rate of 99.35% and an average ablation zone size of 32.47 mm. At the 12-month follow-up, the complete ablation rate and intrapulmonary progression-free survival rates were 90.48% and 88.89%, respectively. The results of patients with ground-glass nodules (GGNs) were superior to those of the patients with solid nodules (12-month complete ablation rates: solid vs. pure GGN vs. mixed GGN: 82.14% vs. 100% vs. 96.08%, p = 0.007). No device defects were reported. Complications such as pneumothorax, haemoptysis, pleural effusion, pulmonary infection and pleural pain were observed in 3.97%, 6.35%, 8.73%, 11.11% and 10.32% of patients, respectively. Two subjects died during the follow-up period., Conclusion: Transbronchial RFA utilizing an automatic saline microperfusion system is a viable, safe and efficacious approach for the treatment for lung tumours, particularly for patients with GGNs., (© 2024 The Author(s).

Due to its simple process and adaptability to large-area deposition, chemical bath deposition (CBD) is one of the preparation methods for the SnO 2 layer in highly efficient "n-i-p" structured perovskite solar cells (PSCs). However, the residual thioglycolic acid (TGA) on the CBD-SnO 2 surface affects the stability of PSCs and the carrier transport at the CBD-SnO 2 /perovskite interface, hindering the further development of this method. This work demonstrates a method for the reutilization of surface groups to construct molecular bridges. This strategy utilizes the substitution reaction between the residual thiol group on the CBD-SnO 2 surface and the iodine group of iodoacetamide (IAM) to form the IAM structure. The IAM structure not only assists the perovskite grain crystallization but also increases the electronic cloud density of the CBD-SnO 2 surface. Consequently, the charge mobility of the CBD-SnO 2 is enhanced and the energy band alignment at the CBD-SnO 2 /perovskite interface is optimized. A champion device with the IAM structure achieved a power conversion efficiency (PCE) of 22.41% while it maintained 80% of its original PCE after placing at 65 °C in nitrogen filled atmosphere for over 300 h and in an environment at 25 °C and 50 ± 5% relative humidity for over 1000 h, respectively., (© 2024 Wiley‐VCH GmbH.)
