To achieve the desired delivery effect, extracellular vesicles (EVs) must bypass rapid clearance from circulation and exhibit affinity for target cells; however, it is difficult to simultaneously incorporate two materials into EVs. Post-insertion is a general modification method that can be performed by simply mixing different solutions. Previously, we have developed a microfluidic post-insertion method that supported fast and upscaled modification of EVs using KK-modified high-functionality and -quality (HFQ) lipids. Here, we used microfluidic post-insertion to achieve simultaneous incorporation of polyethylene glycol (PEG) lipids and KK or RGD-modified HFQ lipids into milk-derived EVs to avoid uptake from the reticuloendothelial system and increase the uptake into target cells. PEG lipid and HFQ lipids were formulated to produce micelles and subsequently mixed with EV solution using a microfluidic device. Compared to bulk mixing, microfluidic post-insertion showed higher cellular association. Altered cellular association capacities and endocytic pathways indicated simultaneous incorporation. The cellular association of modified EVs can be adjusted by altering the ratio of (EK) 4 -KK in micelles with slight changes in physicochemical properties. Furthermore, microfluidic post-insertion is also suitable for (SG) 5 -RGD, which is insoluble in phosphate-buffered saline (PBS). Our results may be valuable for the development and manufacture of functional EVs as drug delivery systems for clinical applications., Competing Interests: Declaration of competing interest The author reports no conflicts of interest in this work., (Copyright © 2024 The Authors.

The presence of heavy metal ions in the environment is a long-lasting problem that requires the simultaneous detection of Hg(II) and Pb(II) which is both vital and challenging. This present study examines a simplified and effective approach for synthesizing multi-walled carbon nanotube-copper manganese oxide (MWCNT-CuMn 2 O 4 ) and multi-walled carbon nanotube-zinc manganese oxide (MWCNT-ZnMn 2 O 4 ) nanocomposites for electrochemical detection of heavy metal ions. The nanocomposites MWCNT-CuMn 2 O 4 and MWCNT-ZnMn 2 O 4 exceptional electrochemical performance was evaluated using Square Wave Anodic Stripping Voltammetry (SWASV). The fabricated MWCNT-ZnMn 2 O 4 demonstrated lower values of Electrochemical Impedance Spectroscopy (EIS) with charge transfer resistance (R ct ) of approximately 34.13 Ω. Remarkably, the MWCNT-ZnMn 2 O 4 electrochemical sensor exhibited the widest linear ranges of 0.5-10 μM with sensitive detection limits (0.011 μM for Hg(II) and 0.014 μM for Pb(II)). Interestingly, the MWCNT-ZnMn 2 O 4 sensor showed excellent capability in detecting Hg(II) and Pb(II) in real water samples with a recovery percentage of 94.1% and 91.3%. Overall, the MWCNT-ZnMn 2 O 4 modified GCE showcased superior selectivity, sensitivity, reproducibility, stability, and repeatability., Competing Interests: Declarations.

The material with high adsorption capacity and selectivity is essential for recovering rare earth elements (REE S ) from ammonium (NH 4 + -N)-rich wastewater. Although the emerging metal-organic framework (MOF) has gained intensive attention in REE S recovery, there are scientific difficulties unsolved regarding restricted adsorption capacity and selectivity, hindering its extensive engineering applications. In this work, a diethylenetriamine pentaacetic (DTPA)-modified MOF material (MIL-101(Cr)-NH-DTPA) was prepared through an amidation reaction. The MIL-101(Cr)-NH-DTPA showed enhanced adsorption capacity for La(III) (69.78 mg g -1 ), Eu(III) (103.01 mg g -1 ) and Er(III) (83.41 mg g -1 ). The adsorption isotherm and physical chemistry of materials indicated that the adsorption of REEs with MIL-101(Cr)-NH-DTPA was achieved via complexation instead of electrostatic adsorption. Such complexation reaction was principally governed by -COOH instead of -NH 2 or -NO 2 . Meanwhile, the resulting material remained in its superior activity even after five cycles. Such a constructed adsorbent also exhibited excellent selective adsorption activity for La(III), Eu(III), and Er(III), with removal efficiency reaching 70% in NH 4 + -N concentrations ranging from 100 to 1500 mg L -1 . This work offers underlying guidelines for exploitation an adsorbent for REEs recovery from wastewater., 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.

Background: Induced abortion can seriously harm the physical and mental health of adolescent women. Long-acting reversible contraception (LARC) can effectively reduce unplanned pregnancies and prevent repeated abortions among adolescents. This study aimed to analyse the factors affecting the choice of LARC among adolescents in Chongqing of China., Methods: A total of 555 adolescents who underwent induced abortions for unplanned pregnancies between January 2019 and October 2021 were selected as study subjects. Logistic regression analysis was used to determine the factors affecting adolescent LARC choices following induced abortions., Results: The factors that affected adolescent LARC choices included an average monthly income ≥ ¥3000 (OR = 3.432, 95% CI: 1.429∼8.244), history of previous abortions (OR = 3.141, 95% CI: 1.632∼6.045), worrying about unplanned pregnancy (OR = 0.365, 95% CI: 0.180∼0.740), parental support for using LARC (OR = 3.549, 95% CI: 1.607∼7.839), sexual partners' support for using LARC (OR = 2.349, 95% CI: 1.068∼5.167), concerns about using LARC (OR = 0.362, 95% CI: 0.176∼0.745), and willingness to use free IUDs (OR = 13.582, 95% CI: 7.173∼25.717)., Conclusion: Cost is one of the factors affecting LARC choices. Parents and sexual partners may play important role in the choice of LARC.

Multimodal summarization (MS) for videos aims to generate summaries from multi-source information (e.g., video and text transcript), showing promising progress recently. However, existing works are limited to monolingual scenarios, neglecting non-native viewers' needs to understand videos in other languages. It stimulates us to introduce multimodal cross-lingual summarization for videos (MCLS), which aims to generate cross-lingual summaries from multimodal input of videos. Considering the challenge of high annotation cost and resource constraints in MCLS, we propose a knowledge distillation (KD) induced triple-stage training method to assist MCLS by transferring knowledge from abundant monolingual MS data to those data with insufficient volumes. In the triple-stage training method, a video-guided dual fusion network (VDF) is designed as the backbone network to integrate multimodal and cross-lingual information through diverse fusion strategies in the encoder and decoder; What's more, we propose two cross-lingual knowledge distillation strategies: adaptive pooling distillation and language-adaptive warping distillation (LAWD), designed for encoder-level and vocab-level distillation objects to facilitate effective knowledge transfer across cross-lingual sequences of varying lengths between MS and MCLS models. Specifically, to tackle lingual sequences of varying lengths between MS and MCLS models. Specifically, to tackle the challenge of unequal length of parallel cross-language sequences in KD, LAWD can directly conduct cross-language distillation while keeping the language feature shape unchanged to reduce potential information loss. We meticulously annotated the How2-MCLS dataset based on the How2 dataset to simulate MCLS scenarios. Experimental results show that the proposed method achieves competitive performance compared to strong baselines, and can bring substantial performance improvements to MCLS models by transferring knowledge from the MS model.

Tuberculosis (TB) remains one of the deadliest chronic infectious diseases globally. Early diagnosis not only prevents the spread of TB but also ensures effective treatment. However, the absence of non-sputum-based diagnostic tests often leads to delayed TB diagnoses. Inflammation is a hallmark of TB, we aimed to identify biomarkers associated with TB based on immune profiling. We collected 222 plasma samples from healthy controls (HCs), disease controls (non-TB pneumonia; PN), patients with TB (TB), and cured TB cases (RxTB). A high-throughput protein detection technology, multiplex proximity extension assays (PEA), was applied to measure the levels of 92 immune proteins. Based on differential analysis and the correlation with TB severity, we selected 9 biomarkers (CXCL9, PDL1, CDCP1, CCL28, CCL23, CCL19, MMP1, IFNγ and TRANCE) and explored their diagnostic capabilities through 7 machine learning methods. We identified combination of these 9 biomarkers that distinguish TB cases from controls with an area under the receiver operating characteristic curve (AUROC) of 0.89-0.99, with a sensitivity of 82-93% at a specificity of 88-92%. Moreover, the model excels in distinguishing severe TB cases, achieving AUROC exceeding 0.95, sensitivities and specificities exceeding 93.3%. In summary, utilizing targeted proteomics and machine learning, we identified a 9 plasma proteins signature that demonstrates significant potential for accurate TB diagnosis and clinical outcome prediction.

Background: Osteonecrosis of the femoral head (ONFH) is a significant postoperative complication following femoral neck fractures (FNFs) in adolescents, that has garnered considerable attention from researchers. Despite this interest, the incidence of ONFH in adolescents post-FNF surgery has not been extensively evaluated. To contribute to the body of research, we performed a meta-analysis utilizing articles sourced from multiple databases, with an emphasis on the rate of ONFH occurrence in young adolescents following FNF surgery., Objective: The purpose of this study was to investigate the incidence of ONFH after FNFs in adolescents worldwide and analyse potential risk factors affecting its occurrence to provide guidance for the treatment and rehabilitation after FNFs in adolescents and reduce the incidence of ONFH., Methods: A comprehensive search of medical literature databases, including MEDLINE, Web of Science, the Cochrane Library, and Embase, was conducted to identify relevant studies on ONFH and its associated risk factors after surgical treatment for FNFs in adolescents, covering the period from the establishment of the database to April 2024. Studies that did not meet the inclusion criteria were excluded. The study was conducted based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Literature extraction, management, and data entry were performed using Zotero 6.0 and Excel 2016. The meta-analysis was conducted using R Studio 4.2.2. Subgroup analysis, sensitivity analysis, and assessment of publication bias were performed to explore sources of heterogeneity and evaluate the reliability of the results. This study has been registered on Prospero. (registration number: CRD4202452794; date of registration: 03/04/2024) RESULTS: A total of 17 publications involving 862 patients with FNFs were included in this meta-analysis. The findings revealed that the incidence of ONFH after FNF surgery in adolescents was 24.02% [95% CI (0.2118, 0.2712)]. The included studies demonstrated good consistency, and no publication bias was observed., Conclusion: This study revealed that the incidence of ONFH after FNFs in adolescents is high (24.02%).

Background: Constipation significantly impacts quality of life and is a common public health issue. For affected individuals, especially those who are inactive and experience constipation symptoms, it is recommended to engage in physical activity (PA) to improve their condition. However, the relationship between PA and improvement in constipation remains unclear. We performed this systematic review of cohort studies to evaluate this potential association., Methods: We systematically searched the Embase, Cochrane Library, PubMed, and CINAHL databases for all cohort studies examining the relationship between PA and constipation from the inception of the databases up to 5 November 2023. We calculated the reported risk ratios (RRs) and 95% confidence intervals (CIs), conducted a random effects model, and performed a subgroup analysis based on factors such as gender, geographic region, and PA intensity to comprehensively explore the link between PA and constipation. Furthermore, we used the Newcastle-Ottawa Scale to evaluate the quality of the studies included in our analysis., Results: The analysis included 13 studies with 119 426 participants and 63 713 cases. The results indicated that higher levels of PA were associated with a decreased risk of constipation compared with lower levels of PA (RR = 0.69; 95% CI = 0.88-0.83) and moderate levels of PA (RR = 0.87; 95% CI = 0.79-0.95). Furthermore, adherence to international PA guidelines was correlated with a significantly reduced risk of constipation (RR = 0.87; 95% CI = 0.81-0.93). Notably, the risk of constipation was lowered among Asian populations (RR = 0.67; 95% CI = 0.56-0.79) and Oceanian populations (RR = 0.72; 95% CI = 0.63-0.83) who engaged in regular PA. Moreover, when comparing the risk of constipation between men and women collectively, PA was associated with a 34% lower risk (RR = 0.66; 95% CI = 0.55-0.80)., Conclusions: The study findings indicated that moderate to high levels of PA significantly reduced the risk of constipation, showing a negative correlation between PA and constipation., Registration: PROSPERO: CRD42023479653., Competing Interests: Disclosure of interest: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interest., (Copyright © 2024 by the Journal of Global Health.

In-situ synthesized hollow transition metal chalcogenides have gained significant attention on account of their excellent electrochemical properties. Here, Ni-doped V-MOF (V(Ni)-MOF) nanorod arrays as precursor are first grown on nickel foam (NF). Subsequently, the nanorod arrays are converted into V(NiCo)-OH hollow nanotube arrays with cross-linked nanosheets by Co 2+ etching. Finally, V(NiCo)-OH/NF is converted into V(NiCo)-X/NF (X = O, S and Se) by annealing or ion exchange. Due to the unique morphology of hollow nanotube arrays with cross-linked nanosheets and synergistic effect of multi-metal components, the V(NiCo)-Se/NF achieves an outstanding specific capacity (1806.7 C g -1 at 1 A g -1 ), which is higher than that of V(NiCo)-O/NF (1208.3 C g -1 ) and V(NiCo)-S/NF (1558.4 C g -1 ). In addition, the capacity retention rate is 91.7 % (at 10 A g -1 after 10, 000 cycles). Utilizing V(NiCo)-Se/NF (positive) and activated carbon/NF (negative), the hybrid supercapacitor (HSC) achieves an impressive high energy density of 114.8 Wh kg -1 (at 679.5 W kg -1 ). Moreover, two HSCs in series can power the LED and stopwatch, and keep working for more than 60 min, displaying good practical application capabilities., 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.

Diabetic kidney disease (DKD) is a prevalent microvascular complication of diabetes mellitus and a primary cause of end-stage renal disease (ESRD). Increasing studies suggest that immune cells are involved in regulating renal inflammation, which contributes to the progression of DKD. Compared with conventional methods, single-cell sequencing technology is more developed technique that has advantages in resolving cellular heterogeneity, parallel multi-omics studies, and discovering new cell types. ScRNA-seq helps researchers to analyze specifically gene expressions, signaling pathways, intercellular communication as well as their regulations in various immune cells of kidney biopsy and urine samples. It is still challenging to investigate the function of each cell type in the pathophysiology of kidney due to its complex and heterogeneous structure and function. Here, we discuss the application of single-cell transcriptomics in the field of DKD and highlight several recent studies that explore the important role of immune cells including macrophage, T cells, B cells etc. in DKD through scRNA-seq analyses. Through combing the researches of scRNA-seq on immune cells in DKD, this review provides novel perspectives on the pathogenesis and immune therapeutic strategy for DKD., Competing Interests: Declarations Competing interests The authors declare no competing interests., (© 2024.

This investigation seeks to scrutinize the relationships between body composition metrics and the clinical outcomes observed in patients with cholangiocarcinoma (CCA). A comprehensive exploration was conducted across three prominent online databases: Embase, PubMed, and the Cochrane Library. This endeavor spanned the entirety of each database up to the cutoff date of September 29, 2023. To evaluate the quality of the included studies, the Newcastle-Ottawa scale was employed. This comprehensive analysis included a total of 26 articles with a combined patient cohort of 4398 individuals. The results demonstrated that CCA patients with low skeletal muscle index (SMI) had significantly inferior OS (HR: 1.93, p < 0.001) and RFS (HR: 2.02, p < 0.001), as well as a higher incidence of postoperative complications (OR: 1.69, 95% CI: 1.20-2.38, p < 0.001) compared to those with high SMI. The presence of sarcopenia in CCA patients was significantly related to poorer OS (HR: 1.96, p < 0.001) and RFS (HR: 2.05, p < 0.001), and a higher rate of postoperative complications (OR: 1.39, p = 0.049) in comparison to those without sarcopenia. Moreover, lower psoas muscle index (PMI) and myosteatosis were associated with shorter OS (PMI, HR: 1.56, p < 0.001; myosteatosis, HR: 1.49, p = 0.001) and RFS (PMI, HR: 2.16, p < 0.001; myosteatosis, HR: 1.35, p = 0.023). Our findings highlight incorporating body composition screening into clinical practice can help develop treatment strategies and optimize perioperative care, potentially improving patient outcomes., Competing Interests: Declarations Ethics approval and consent to participate Not applicable.

Introduction: Cancer-related fatigue (CRF) is one of the most common and painful symptoms in patients with prostate cancer (PCa). Moreover, PCa patients who receive the androgen deprivation therapy (ADT) are more likely to develop CRF. Baduanjin exercise has been shown to improve CRF in some cancers. However, such effects have not been verified in patients with PCa treated with the ADT. So, this study was designed as a randomised controlled trial (RCT) to explore the effects of Baduanjin exercise on CRF in PCa patients treated with the ADT., Methods and Analysis: This study will be a single-centre, assessor and statistician blinded, RCT consisting of a 12 week intervention and 12 week follow-up. Patients with PCa who meet the inclusion criteria will be recruited from Shanghai Hudong Hospital. Participants will be randomly assigned to Baduanjin exercise group (n=42) and the control group (n=42), performing 12 weeks of Baduanjin exercise or reeiving the standard care. The primary outcome will be the clinical effect of Baduanjin exercise on CRF in PCa patients, which will be measured using the Piper Fatigue Self-Assessment (PFS) scale, a multidimensional measure of CRF using three different dimensions: somatic, emotional and cognitive. The secondary outcome will be the clinical effect of the Baduanjin exercise on the patient's level of fatigue, sleep, depression and life quality at the time, which will be assessed by the Brief Fatigue Inventory (BFI), the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI) and the Functional Assessment of Cancer Therapy-Prostate (FACT-P)., Ethics and Dissemination: This study has been approved by Shanghai Hudong Hospital Ethics Committee, Shanghai province (2022 SHHDKY08). The trial results will be submitted to conferences and peer-reviewed journals., Trail Registration Number: ChiCTR2300074293., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

A series of development technologies of "horizontal well plus volume fracturing" have been established to achieve an annual output of one million tons of crude oil in 7 the Mahu tight conglomerate reservoir. However, such oil fields generally face problems such as rapid pressure drop, rapid production decline, difficulty in water injection, and gas channeling, seriously affecting the beneficial development of tight conglomerate reservoirs. To solve these problems, in this study, we carried out the feasibility experiment of different gas injection developments and the potential evaluation of enhanced oil recovery based on the combination of laboratory experiments and numerical simulation. The results show that CO 2 , rich gas, and dry gas can be miscible with crude oil in X oilfield under the original formation conditions. Both CO 2 and hydrocarbon gas have expansion and viscosity reduction abilities. Under the same mole fraction of injected gas, the volume expansion ability and viscosity reduction ability of CO 2 to crude oil are 2.14 and 2.25 times that of hydrocarbon gas, respectively. Numerical simulation results show that the well pattern suitable for gas injection and energy supplement is a vertical well injection and horizontal well production, and the angle between the horizontal well direction and the horizontal maximum principal stress direction is between 0° and 30°. Both laboratory experiments and numerical simulations show that the CO 2 injection medium has the best recovery effect, which can increase the recovery rate by 13.8% compared with the depletion development. This research provides insights into the effective development of tight conglomerate reservoirs., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

In this study, a highly branched glucomannan (SCP-1) from Schizophyllum commune fruiting body with good solubility was isolated, and its structural characteristics and antitumor properties were analyzed. The monosaccharides of SCP-1 were fucose, glucosamine hydrochloride, galactose, glucose and mannose with a relative molar ratio of 14:6:210:593:177, and the molecular weight (Mw) of SCP-1 was 15.1 kDa. SCP-1 showed a rough and dense surface, and it was aggregated to particles in distilled water, though it might have triple-helix conformation. The main backbone chain of SCP-1 was →[3)-β-D-Glcp-(1] 3 →3)-β-D-Glcp-(1→2)-α-D-Manp-(1→2)-α-D-Manp-(1→3)-α-D-Glcp-(1→ and three sides chains including α-D-Glcp-(1→[6)-β-D-Glcp-(1] 2 →, α-D-Glcp-(1→3)-α-D-Manp-(1→ and α-D-Glcp-(1→[6)-α-D-Galp-(1] 3 → were linked with 1,6-glycosidic bond, which was significantly different with the schizophyllan isolated from the mycelia of S. commune. SCP-1 could significantly inhibit the growth of A549 cells, the inhibition rate reached 41.62 % and the percentage of cells in S phase increased from 27.17 % to 56.40 % (400 μg/mL, 48 h). Moreover, SCP-1 could induce cell apoptosis and the total apoptosis rate reached 28.13 %. SCP-1 exerted apoptosis inducing effect probably by reducing the expression ratio of Bcl-2/Bax and the p-PI3K, p-Akt and p-mTOR expression level. The results showed that SCP-1 might have the potential to act as an antitumor agent for lung cancer therapy., 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.

CRISPR/Cas12a is a highly promising detection tool. However, detecting single nucleotide variations (SNVs) remains challenging. Here, we elucidate Cas12a specificity through crRNA engineering and profiling of single- and double-base mismatch tolerance across three targets. Our findings indicate that Cas12a specificity depends on the number, type, location, and distance of mismatches within the R-loop. We also find that introducing a wobble base pair at position 14 of the R-loop does not affect the free energy change when the spacer length is truncated to 17 bp. Therefore, we develop a new universal specificity enhancement strategy via iterative crRNA design, involving truncated spacers and a wobble base pair at position 14 of the R-loop, which tremendously increases specificity without sacrificing sensitivity. Additionally, we construct a PAM-free one-pot detection platform for SARS-CoV-2 variants, which effectively distinguishes SNV targets across various GC contents. In summary, our work reveals new insights into the specificity mechanism of Cas12a and demonstrates significant potential for in vitro diagnostics., (© 2024. The Author(s).)

Background: The occurrence and development of hematologic tumors are closely linked to cellular senescence. However, the molecular characteristics associated with this phenomenon in chronic myeloid leukemia (CML) have not been thoroughly investigated., Methods: The cellular senescence score was calculated using gene set variation analysis. Consensus clustering algorithm was used to identify the molecular subtypes associated with cellular senescence. Clinical samples were collected for sequencing analysis to verify the expression of critical cellular senescence-related genes (CSRG). The effect of targeted inhibition of IGFBP2 on the malignant phenotype of CML-resistant cells was studied by cell experiments., Results: The cellular senescence score in CML samples was significantly lower compared to normal samples. Higher expression of immune checkpoint markers correlated with increased cellular senescence scores. We identified two distinct molecular subtypes (C1 and C2) related to cellular senescence. The C1 subtype exhibited enhanced metabolic function and DNA damage repair capacity, while the C2 subtype showed higher infiltration of immune effector cells and activity in immune-related signaling pathways. We also discovered a group of drugs that displayed significant sensitivity differences between these two molecular subtypes, with the C2 subtype showing greater responsiveness to immunotherapy. Four critical cellular senescence-related genes (CSRGs), namely IGFBP2, IL7R, PLAU, and SUN1 demonstrated high diagnostic value for CML. We validated the expression levels of these four genes using clinical samples and confirmed through cell experiments that targeted inhibition of IGFBP2 effectively suppressed proliferation of resistant CML cells, promoted apoptosis, and enhanced therapeutic sensitivity to imatinib., Conclusion: Our study conducted a comprehensive analysis on CSRG expression characteristics in CML and explored potential correlations between cellular senescence and immune function. The identification of molecular subtypes provides valuable insights into assessing individual patients' biological characteristics for guiding clinical treatment decisions. Additionally, IGFBP2 has emerged as a promising therapeutic target for therapy-resistant cases of CML., Competing Interests: The authors declare that they have no conflicts of interest., (© 2024 Xu et al.)

Electrocatalytic nitrogen (N 2 ) reduction reaction (eNRR) is a promising route for sustainable ammonia (NH 3 ) generation, but the eNRR efficiency is dramatically impeded by sluggish reaction kinetics. Herein, inspired by the dynamic extension-contraction of sea anemone tentacles in response to environmental changes, we propose a biomimetic elastic Mo single-atom protrusion on vanadium oxide support (pSA Mo/VOH) electrocatalyst featuring a symmetry-breaking Mo site and an elastic Mo-O 4 pyramid for efficient eNRR. In situ spectroscopy and theoretical calculations reveal that the protruding Mo-induced symmetry-breaking structure optimizes the d-electron filling of Mo, enhancing the back-donation to the π* antibonding orbital, effectively polarizing the N≡N bond and reducing the barrier from *N 2 to *N 2 H. Notably, the elastic Mo-O 4 pyramidal structure of pSA Mo provides a dynamic Mo-O microenvironment during continuous eNRR processes. This optimizes the electronic structure of the Mo sites based on different reaction intermediates, enhancing the adsorption of various N intermediates and maintaining low barriers throughout the six-step hydrogenation process. Consequently, the elastic pSA Mo/VOH exhibits an excellent NH 3 yield rate of 50.71±1.12 μg h -1  mg -1 and a Faradaic efficiency of 35.38±1.03 %, outperforming most electrocatalysts., (© 2024 Wiley-VCH GmbH.)

Pomacea canaliculata (Lamarck 1822), a freshwater gastropod indigenous to lower Del Plata Basin of Argentina, has become the most destructive and invasive rice pests in south China since its introduction in the 1980s. In Guangdong, the main production areas for double rice, most of P. canaliculata overwinter in paddy field ditches after late-rice harvesting in mid-November and diapause to temporarily to avoid the damaging effects of extreme low temperatures. This pest aroused from diapause and migrated to the paddy field after early-rice reviving in next late March. Overwintering and cold tolerance of natural P. canaliculata have a non-negligible impact on population dynamics and distribution in the following year. We tested the supercooling capability, levels of cryoprotectant synthesis, activity of antioxidant defense system (antioxidant enzymes and reduced glutathione), and degree of oxidative damage (concentration of malondialdehyde as an index of lipid peroxidation) monthly, using natural P. canaliculata samples with a size-gender structure (i.e., juveniles, female, and male adults) from experimental ponds during the period of mid-November to the following April. P. canaliculata survived the winter with a monthly death rate of 7%-16.5% in coldest January. The supercooling point (SCP) of overwintering P. canaliculata decreased initially before increasing subsequently with monthly changes in water temperature. P. canaliculata accumulated a high glycogen content before December, which depleted towards the end of January, while lipid content reached peak in January and depleted since February. Activity of antioxidant defense system of P. canaliculata exhibited significant monthly differences and showed relatively higher size heterogeneity than monthly variations. The results contribute to the knowledge of adaptability in overwintering P. canaliculata and help to understand the mechanism of the invasive success of this species., (© 2024 Wiley Periodicals LLC.)

Background: The combination of pyrotinib (Py) with cytotoxic agents proved to be effective in early human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC). However, the optimal chemotherapy regimen is unknown. This study attempts to explore it from real-world research data., Methods: Information was collected from patients with early-stage HER2-positive BC from 23 centers across the country. They were categorized into the anthracycline group (A group) and non-anthracycline group (non-A group). Patients in the non-A group were further categorized into the platinum group and non-platinum group and the short-cycle (≤4 cycles) taxane group and long-cycle (>4 cycles) taxane group. Total pathological complete response (tpCR, ypT0/is ypN0) and breast pathological complete response (bpCR, ypT0/is) rates were assessed., Results: A total of 107 patients were enrolled. Postoperative pathology indicated a tpCR rate of 36.8 %, a bpCR rate of 42.1 % in the A group, the non-A group had a tpCR rate of 47.8 %, and a bpCR rate of 53.6 %, with P-values of 0.273 and 0.254, respectively. In the long-cycle taxane group, the tpCR and bpCR rates were 60.8 % and 66.7 %, respectively. In the short-cycle taxane group, the tpCR and bpCR rates were 11.1 % and 16.7 %, respectively (both P<0.001). The platinum group had higher tpCR rate (62.9 % vs. 32.4 %, respectively; P = 0.011) and bpCR rate (65.7 % vs. 41.2 %, respectively; P = 0.041)., Conclusion: As for a neoadjuvant therapy regimen with Py, an anthracycline-free regimen is feasible. Besides, platinum-containing, long-cycle taxane regimens appear to achieve superior efficacy under anthracycline-removed conditions., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024.

The imbalance of vascular endothelial cell homeostasis is the key mechanism for the progression of many vascular diseases. RNA modification, particularly N 6 -Methyladenosine (m 6 A), plays important function in numerous biological processes. Nevertheless, the regulatory function of m 6 A RNA methylation in endothelial dysfunction remains insufficiently characterized. In this study, we established that the m 6 A methyltransferase METTL3 is critical for regulating endothelial function. Functionally, depletion of METTL3 results in decreased endothelial cells proliferation, survival and inflammatory response. Conversely, overexpression of METTL3 elicited the opposite effects. Mechanistically, MeRIP-seq identified that METTL3 catalyzed m 6 A modification of TRAF1 mRNA and enhanced TRAF1 translation, thereby up-regulation of TRAF1 protein. Over-expression of TRAF1 successfully rescued the inhibition of proliferation and adhesion of endothelial cells due to METTL3 knockdown. Additionally, m 6 A methylation-mediated TRAF1 expression can be reversed by the demethylase ALKBH5. Knockdown of ALKBH5 upregulated the level of m 6 A and protein level of TRAF1, and also increased endothelial cells adhesion and inflammatory response. Collectively, our findings suggest that METTL3 regulates vascular endothelium homeostasis through TRAF1 m 6 A modification, suggesting that targeting the METTL3-m 6 A-TRAF1 axis may hold therapeutic potential for patients with vascular diseases., 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.

Brain functional modular organization changes with age. Considering the brain as a dynamic system, recent studies have suggested that time-varying connectivity provides more information on brain functions. However, the spontaneous reconfiguration of modular brain structures over time during aging remains poorly understood. In this study, we investigated the age-related dynamic modular reconfiguration using resting-state functional MRI data (615 participants, aged 18-88 years) from Cam-CAN. We employed a graph-based modularity analysis to investigate modular variability and the transition of nodes from one module to another in modular brain networks across the adult lifespan. Results showed that modular structure exhibits both linear and nonlinear age-related trends. The modular variability is higher in early and late adulthood, with higher modular variability in the association networks and lower modular variability in the primary networks. In addition, the whole-brain transition matrix showed that the times of transition from other networks to the dorsal attention network were the largest. Furthermore, the modular structure was closely related to the number of cognitive components and memory-related cognitive performance, suggesting a potential contribution to flexibility cognitive function. Our findings highlighted the notable dynamic characteristics in large-scale brain networks across the adult lifespan, which enhanced our understanding of the neural substrate in various cognitions during aging. These findings also provided further evidence that dedifferentiation and compensation are the outcomes of functional brain interactions., (© 2024 Society for Psychophysiological Research.)

Alcohol-associated liver disease (ALD) poses a significant risk for hepatocellular carcinoma (HCC), comprising various liver conditions from steatosis to cirrhosis. Despite accounting for a third of global HCC cases and deaths, ALD-related HCC lacks characterization compared to viral hepatitis-related HCC. Proposed mechanisms for ALD-related HCC include acetaldehyde toxicity, increased reactive oxygen species, and inflammation. This review examines ALD-associated HCC epidemiology, co-factors like viral hepatitis and metabolic syndrome, surveillance, and treatment challenges. Despite advances in screening and management, ALD-related HCC often presents at advanced stages, limiting treatment options and survival., Competing Interests: Disclosure The authors of this review were supported by the NIH, United States5T32DK060414-18 (National Institute of Diabetes and Digestive and Kidney Diseases, United States, N.B.

Background: Previous studies have shown that macrophage-mediated efferocytosis is involved in immunosuppression in acute myeloid leukemia (AML). However, the regulatory role of efferocytosis in AML remains unclear and needs further elucidation., Methods: We first identified the key efferocytosis-related genes (ERGs) based on the expression matrix. Efferocytosis-related molecular subtypes were obtained by consensus clustering algorithm. Differences in immune landscape and biological processes among molecular subtypes were further evaluated. The efferocytosis score model was constructed to quantify molecular subtypes and evaluate its value in prognosis prediction and treatment decision-making in AML., Results: Three distinct efferocytosis-related molecular subtypes were identified and divided into immune activation, immune desert, and immunosuppression subtypes based on the characteristics of the immune landscape. We evaluated the differences in clinical and biological features among different molecular subtypes, and the construction of an efferocytosis score model can effectively quantify the subtypes. A low efferocytosis score is associated with immune activation and reduced mutation frequency, and patients have a better prognosis. A high efferocytosis score reflects immune exhaustion, increased activity of tumor marker pathways, and poor prognosis. The prognostic predictive value of the efferocytosis score model was confirmed in six AML cohorts. Patients exhibiting high efferocytosis scores may derive therapeutic benefits from anti-PD-1 immunotherapy, whereas those with low efferocytosis scores tend to exhibit greater sensitivity towards chemotherapy. Analysis of treatment data in ex vivo AML cells revealed a group of drugs with significant differences in sensitivity between different efferocytosis score groups. Finally, we validated model gene expression in a clinical cohort., Conclusions: This study reveals that efferocytosis plays a non-negligible role in shaping the diversity and complexity of the AML immune microenvironment. Assessing the individual efferocytosis-related molecular subtype in individuals will help to enhance our understanding of the characterization of the AML immune landscape and guide the establishment of more effective clinical treatment strategies., (© 2024.

Background: The invasive freshwater snail Pomacea canaliculata is an agricultural pest with a certain level of tolerance to abiotic stress. After the harvest of late rice, the snails usually burrow themselves into the soil surface layers to overwinter and pose a renewed threat to rice production in the following year. Revealing the response of snails to environmental stresses is crucial for developing countermeasures to control their damage and spread., Results: In this study, we conducted a 120-day in situ experiment during the winter to investigate the survival and physiological changes of hibernating snails in 0-5 and 5-10 cm soil depths, aiming to explore their overwintering strategies. Our results showed that 73.61%, 87.50%, and 90.28% of male, female, and juvenile snails survived after hibernation for 120 days in 0-10 cm soil depth, respectively. The differences in survival rates based on sex and size of snails potentially reflect the countermeasures of snails to rapidly reproduce after hibernation. Simultaneously, the hibernating snails exhibited the ability to maintain a certain level of body weight. During this period, the snails increased their antioxidant enzyme activities to cope with oxidative stress, and enhanced their lipid storage. The hibernation survival of snails was not significantly affected by different soil depths, indicating that they have the potential to hibernate into deeper soils. Furthermore, snails were capable of increasing their contents of bound water and glycerol to cope with sudden cold spells during hibernation., Conclusion: Our findings emphasize the adaptive changes of P. canaliculata snails overwintering in paddy soils. In future studies, the vulnerabilities of P. canaliculata during hibernation (e.g. shell characteristics, nutrient reserves, and dehydration tolerance, etc.,) should be investigated to develop effective control methods for this period. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)

Human milk oligosaccharides promote the growth and adhesion of Bifidobacteria, thus exerting multiple biological functions on intestinal epithelial cells. Bacterial surface proteins play an important role in bacterial-host intestinal epithelial interactions. In this study, we aimed to investigate the effects of surface proteins extracted from Bifidobacterium bifidum DNG6 (B. bifidum DNG6) consuming 2'-fucosyllactose (2'-FL) on Caco-2 cells monolayer barrier injury induced by lipopolysaccharide, compared with lactose and galacto-oligosaccharides. Our results indicated that 2'-FL may promote the surface proteins of B. bifidum DNG6 to improve intestinal barrier injury by positively regulating the NF-κB signaling pathway, reducing inflammation (TNF-α reduced by 50.34%, IL-6 reduced by 22.83%, IL-1β reduced by 37.91%, and IL-10 increased by 63.47%) and strengthening tight junction proteins (ZO,1 2.39×; claudin,1 2.79×; and occluding, 4.70×). The findings of this study indicate that 2'-FL can further regulate intestinal barrier damage by promoting the alteration of B. bifidum DNG6 surface proteins. The findings of this research will also provide theoretical support for the development of synbiotic formulations., (The Authors.

Hospital wastewater is a critical source of antimicrobial resistance (AMR), which facilitates the proliferation and spread of clinically significant antimicrobial resistance genes (ARGs) and pathogenic bacteria. This study utilized metagenomic approaches, including advanced binning techniques, such as MetaBAT2, MaxBin2, and CONCOCT, which offer significant improvements in accuracy and completeness over traditional binning methods. These methods were used to comprehensively assess the dynamics and composition of resistomes and mobilomes in untreated wastewater samples taken from two general hospitals and one cancer hospital. This study revealed a diverse bacterial landscape, largely consisting of Proteobacteria, Firmicutes, Bacteroidetes, and Actinobacteria, with notable variations in microbial composition among hospitals. Analysis of the top 15 genera showed unique microbial pattern distribution in each hospital: Aeromonas was predominant in 1stHWTS (49.39 %), Acidovorax in the CAHWTS at 16.85 %, and Escherichia and Bacteroides in the 2ndHWTS at 11.44 % and 11.33 %, respectively. A total of 114 pathogenic bacteria were identified, with drug-resistant Aeromonas caviae and Escherichia coli being the most prevalent. The study identified 34 types and 1660 subtypes of ARGs, including important last-resort antibiotic resistance genes (LARGs), such as bla NDM , mcr, and tet(X). Using metagenomic binning, this study uncovered distinct patterns of host-resistance associations, particularly with Proteobacteria and Firmicutes. Network analysis highlighted the complex interactions among ARGs, mobile genetic elements (MGEs), and bacterial species, all contributing to the dissemination of AMR. These findings emphasize the intricate nature of AMR in hospital wastewater and the influence of hospital-specific factors on microbial resistance patterns. This study provides support for implementing integrated management strategies, including robust surveillance, advanced wastewater treatment, and strict antibiotic stewardship, to control the dissemination of AMR. Understanding the interplay among bacterial communities, ARGs, and MGEs is important for developing effective public health measures against AMR., 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.

Purpose: Combining computed diffusion-weighted imaging (DWI) with readout-segmented echo-planar-imaging may shorten acquisition time and improve imaging quality. This study aimed to compare computed vs. acquired DWI qualitatively and quantitatively in visualizing scrotal or testicular lesions., Materials and Methods: We retrospectively enrolled 57 consecutive men who underwent scrotal MRI. Four computed DWI sets (cDWI 800 , cDWI 1000 , cDWI 1200 , and cDWI 1400 ) were generated from acquired DWI with two lower b-values (150 and 600 s/mm 2 ). Acquired DWI (DWI 800 and DWI 1000 ) and computed DWI were compared through qualitative (susceptibility artifact, signal loss artifact, anatomic clarity, and lesion conspicuity) and quantitative assessment (signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and lesion-to-testicular parenchyma contrast ratio (CR))., Results: Computed DWI was prone to signal loss artifact and slightly lower assessment scores in terms of anatomic clarity and lesion conspicuity, comparing with acquired DWI. The SNR of computed and acquired DWI decreased with increasing b value. Under the same b-values (800 and 1,000 s/mm 2 ), there was no difference in the median SNR and CR between computed and acquired DWI. The median CR of cDWI 1400 was significantly higher than that of the other DWI sets excepting cDWI 1200 (P=1.000). The median CNR tended to be lower for computed vs. acquired DWI, while no significant difference (P=0.233)., Conclusions: Computed and acquired DWI were nearly equivalent in both qualitative and quantitative evaluations at the b values of 800 and 1,000 s/mm 2 . Computed DWI could enhance the contrast of scrotal or testicular lesions., (Copyright © 2024 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.)

The impacts of microplastics on the gut microbiota, a crucial component of the health of aquatic animals, remain inadequately understood. This phylogenetically controlled meta-analysis aims to identify general patterns of microplastic effects on the alpha diversity (richness and Shannon index), beta diversity, and community structure of gut microbiota in aquatic animals. Data from 63 peer-reviewed articles on the Web of Science were synthesized, encompassing 424 observations across 31 aquatic species. The analysis showed that microplastics significantly altered the community structure of gut microbiota, with between-group distances being 87.75% higher than within-group distances. This effect was significant even at environmentally relevant concentrations (≤1 mg L -1 ). However, their effects on richness, Shannon index, and beta diversity (community variation) were found to be insignificant. The study also indicated that the effects of microplastics were primarily dependent on their concentration and size, while the phylogeny of tested species explained limited heterogeneity. Furthermore, variations in gut microbiota alpha diversity, beta diversity, and community structure were correlated with changes in antioxidant enzyme activities from the liver and hepatopancreas. This implies that gut microbiota attributes of aquatic animals may provide insights into host antioxidant levels. In summary, this study illuminates the impacts of microplastics on the gut microbiota of aquatic animals and examines the implications of these effects for host health. It emphasizes that microplastics mainly alter the community structure of gut microbiota rather than significantly affecting richness and diversity., 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.

Thymidine Kinase 1 (TK1) is a pivotal enzyme in fundamental biochemistry and molecular diagnosis, but recognition and molecule detection is a challenging task. Here, we constructed a DNA-integrated hybrid nanochannel sensor for TK1 activity and inhibition assay. Single-stranded DNA containing thymidine was used as a substrate to functionalize the nanochannels, restricting the ion current through channels. With kinase, the thymidine at the termini of the substrate DNA is phosphorylated, elevating surface charge density and mitigating the pore-obstruction effect by increasing transmembrane ion current. The kinase-induced distinctness can be accurately monitored by this hybrid nanodevice, which benefits from its high sensitivity to the change of surface charge. The excellent analytical performance in both kinase enzyme activity and inhibition analysis resulted in efficient and selective evaluation in human serum. Furthermore, compared to current approaches, it greatly simplifies and offers a direct method of analysis, making it a promising sensor technology for cancer management as well as the activities of multiple types of nucleic acid kinases., 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.

Background: Tuberculosis (TB) is an infectious disease which has long threatened human health, and new molecular diagnostic markers for its diagnosis are urgently needed. The study was designed to analyze the expression of hydroxyproline (HYP) in different specimens of pulmonary TB (PTB) and assess its auxiliary diagnostic value alone or in combination with the TB infection T lymphocyte spot assay (TSPOT.TB)., Methods: According to the inclusion criteria, 43 healthy controls (HCs) and 39 patients with nontuberculous general respiratory diseases were included as the respiratory control (RC) group, while 42 patients with newly treated TB were included as the PTB group. The expression of HYP in serum, urine, and bronchoalveolar lavage fluid (BALF) was detected with a HYP detection kit. Correlation analysis was used to detect the correlation of HYP and clinical indicators. Receiver operating characteristic (ROC) curve analysis was used to determine the sensitivity and specificity of HYP in diagnosing TB, both when used alone and in combination with TSPOT.TB., Results: The expression of HYP in serum of patients with TB was significantly increased as compared to that in controls (P=0.03), but there was no significant difference in the expression of HYP in urine (P>0.05). Compared with the general pneumonia control group, the expression of HYP in BALF of the PTB group was significantly increased (P<0.001). HYP expression in serum was positively correlated with C-reactive protein (CRP) level (r=0.4661, P=0.002), neutrophil (r=0.3338, P=0.03) and monocyte count (r=0.3462, P=0.02), and was negatively correlated with serum albumin expression (r=-0.3575, P=0.02). The expression of HYP in urine was positively correlated with neutrophil count (r=0.3508, P=0.02), neutrophil percentage (r=0.3804, P=0.047), and monocyte count (r=0.3263, P=0.04) but was negatively correlated with serum albumin expression (r=-0.4031, P=0.008). The expression of HYP in BALF was positively correlated with CRP (r=0.3652, P=0.02) but not with other indexes (P>0.05). ROC curve analysis indicated that the sensitivity, specificity, and area under the curve (AUC) of blood HYP were 66.67%, 72.09%, and 0.6481, respectively, while those of its combined diagnosis with TSPOT.TB were 78.57%, 96.77%, and 0.8690, respectively. The sensitivity, specificity, and AUC of HYP in BALF were 67.74%, 64.29%, and 0.7435, respectively, while those of its combined diagnosis with TSPOT.TB were 78.59%, 93.55%, and 0.8606, respectively., Conclusions: The expression of HYP in the serum and BALF of patients with PTB was higher than that of control group, and the expression of HYP was correlated with some clinical indicators. HYP demonstrated good sensitivity and specificity for the primary screening of PTB and higher sensitivity and specificity in the diagnosis of HYP when combined with TSPOT.TB. It may thus have certain value for auxiliary diagnosis in clinic., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://jtd.amegroups.com/article/view/10.21037/jtd-24-1585/coif).

Microscopic study of the nucleation and growth of atomic layer deposition (ALD) dielectrics onto carbon nanotubes (CNTs) is an essential while challenging task toward high-performance devices. Here, we capture the morphological evolution and growth behaviors of ALD-HfO 2 onto SiO 2 /Si-supported aligned CNT arrays (A-CNTs) under three ALD recipes via cross-sectional high-resolution scanning transmission electron microscopy. The HfO 2 in ALD I (200 °C) preferentially nucleates on the SiO 2 substrate in heterogeneous growth mode, resulting in films with considerable pinholes, while ALD II (90 °C) and III (90 °C and extra H 2 O presoak) exhibit homogeneous growth with nucleation on both SiO 2 and CNTs, yielding uniform films. Arrangement defects in A-CNTs exacerbate nonuniformity of HfO 2 and tube-tube separation plays deterministic roles affecting the HfO 2 -CNT interfacial morphology. Electrical measurements from A-CNTs metaloxide-semiconductor devices validate these findings. Our investigation contributes valuable insights for optimizing ALD processes for enhanced dielectric integration on A-CNTs in next-generation electronics.

Metal halide perovskite light-emitting diodes (PeLEDs) and large-area perovskite color conversion layers for liquid crystal display exhibit great potential in the field of illumination and display. Blade-coating method stands out as a highly suitable technique for fabricating large-scale films, albeit with challenges such as uneven nucleation coverage and non-uniformity crystallization process. In this work, we developed an in-situ characterization measurement system to monitor the perovskite nucleation, and crystallization process. By incorporating formamidine acetate (FAAc) into perovskite precursor solutions, the nucleation rate and nuclei density of perovskite were increased, leading to more uniform nucleation. In addition, we inserted a layer of [2-(9H-carbazol-9-yl)ethyl] phosphonic acid above the poly(9-vinylcarbazole) hole transport layer. This layer acts as an anchor for the perovskite nano-crystal nuclei formed in the precursor, enhancing the steric hindrance of the solute and subsequently slowing down the crystal growth rate, thereby improving crystal quality. Based on these improvements, large-area perovskite nano-polycrystalline films with significantly improved uniformity and enhanced photoluminescence quantum yield were obtained. A small-area PeLED (2 mm × 2 mm) with a maximum external quantum efficiency of 25.91% was realized, marking the highest record of PeLED prepared by blade-coating method to date. An ultra-large-area PeLED (5 cm × 7 cm) was also prepared, which is the largest PeLED prepared by the solution method reported so far., (Copyright © 2024 Science China Press.

Objective: To summarize the clinical features, imaging characteristics, and surgical diagnosis and treatment experience of mediastinal extramedullary hematopoiesis., Methods: By summarizing and analyzing the case data and reviewing the literature, one case of posterior mediastinal extramedullary hematopoiesis on thoracoscopic biopsy in our department was summarized., Conclusion: Posterior mediastinal extramedullary hematopoiesis is a response to failure of bone marrow erythropoiesis, which is relatively rare clinically, and diagnosis requires a combination of patient history and imaging, puncture biopsy or thoracoscopic excisional biopsy can provide a pathological diagnosis, and surgical complete resection is the main treatment modality., (© 2024.

Background: In the context of spinal cord injury (SCI), infiltrating macrophages assume prominence as the primary inflammatory cells within the lesion core, where the fibrotic scar is predominantly orchestrated by platelet-derived growth factor receptor beta (PDGFRβ + ) fibroblasts. Galectin-3, a carbohydrate-binding protein of the lectin family, is notably expressed by infiltrating hematogenous macrophages and mediates cell-cell interactions. Although Galectin-3 has been shown to contribute to the endocytic internalization of PDGFRβ in vitro, its specific role in driving fibrotic scar formation after SCI has not been determined., Methods: We employed a crush mid-thoracic (T10) SCI mouse model. Galectin-3 inhibition after SCI was achieved through intrathecal injection of the Galectin-3 inhibitor TD139 or in situ injection of lentivirus carrying Galectin-3-shRNA (Lv-shLgals3). A fibrosis-induced mice model was established by in situ injection of platelet-derived growth factor D (PDGFD) or recombinant Galectin-3 (rGalectin-3) into the uninjured spinal cord. Galectin-3 internalization experiments were conducted in PDGFRβ + fibroblasts cocultured in conditioned medium in vitro., Results: We identified the spatial and temporal correlation between macrophage-derived Galectin-3 and PDGFRβ in fibroblasts from 3 to 56 days post-injury (dpi). Administration of TD139 via intrathecal injection or in situ injection of Lv-shLgals3 effectively mitigated fibrotic scar formation and extracellular matrix deposition within the injured spinal cord, leading to better neurological outcomes and function recovery after SCI. Furthermore, the fibrosis-inducing effects of exogenous PDGFD in the uninjured spinal cord could be blocked by TD139. In vitro experiments further demonstrated the ability of PDGFRβ + fibroblasts to internalize Galectin-3, with Galectin-3 inhibition resulting in reduced PDGFRβ expression., Conclusions: Our finding underscores the pivotal role of macrophage-derived Galectin-3 in modulating the sustained internalized activation of PDGFRβ within fibroblasts, providing a novel mechanistic insight into fibrotic scarring post-SCI., (© 2024.

Background: Little evidence exists about whether a combination of healthy lifestyle factors is associated with a lower risk of depressive symptoms among Chinese population. We aimed to investigate the association between combined healthy lifestyle factors and risk of depressive symptoms., Methods: We conducted a baseline survey from July 2021 to December 2023, including 53,642 Chinese adults from general population. A healthy lifestyle score was constructed based on six lifestyle factors (physical activity, smoking status, alcohol consumption, diet, sleep duration, and body mass index). Logistic regression models were used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) adjusted for confounding variables., Results: Each additional healthy lifestyle score was associated with a 20 % lower risk of having depressive symptoms (OR (95 % CI): 0.80 (0.78-0.81)). Compared with individuals with ≤2 healthy lifestyle factors, individuals with all the six healthy lifestyle factors had a 58 % reduced risk of having depressive symptoms (0.42 (0.37-0.47)). After stratification by gender, education and urbanization, the significant inverse association with healthy lifestyle score was stronger in women, individuals with high education, and urban residents. Besides, the significant negative association between healthy lifestyle score and depressive symptoms remained for different severity of depressive symptoms., Limitations: Given the cross-sectional nature of data, we cannot make causal inferences., Conclusions: Our study indicated that adherence to healthy lifestyle factors was associated with a reduced risk of having depressive symptoms among Chinese adults. The observed associations were modified by gender, education and urbanization. These findings warrant further verification in interventional studies., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024 Elsevier B.V.

Aims: The objective of this study was to investigate the associations of dietary and circulating antioxidant vitamins with metabolic syndrome (MetS), and to assess causality using Mendelian randomization (MR)., Methods: This study included 10,308 participants from the National Health and Nutrition Examination Survey. The associations of vitamins A, C, E and carotenoids with MetS were assessed using multivariable weighted logistic regression analysis. Subsequently, the MR approach was employed to test the causal associations, with inverse variance weighted (IVW) serving as the primary analysis., Results: Observationally, dietary vitamin A (OR=0.852, 95%CI: 0.727-0.999), C (OR=0.802, 95%CI: 0.675-0.952), carotene (OR=0.832, 95%CI: 0.706-0.982), and β-carotene (OR=0.838, 95%CI: 0.706-0.995) in quartile 4 had lower incidents of MetS, when compared to quartile 1. Circulating vitamin C and carotene were also present inversely associated with MetS, while the vitamin A and E both increased this risk. IVW-MR confirmed the associations of dietary vitamin A (OR=0.920, 95%CI: 0.861-0.984), vitamin C (OR=0.905, 95%CI: 0.836-0.979) and carotene (OR=0.918, 95%CI: 0.865-0.974) with MetS. However, there was only circulating β-carotene (OR=0.909, 95%CI: 0.857-0.965) was found to be causally associated with MetS., Conclusions: Observational and MR studies have shown that adequate dietary intake of vitamin A, C and carotenoids may help to reduce the risk of MetS., 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 © 2024 Sun, Fan, Yao, Zhao, Jiang, Yang, Mao and Yang.)

Community detection is a critical component of network analysis and a hot topic in social computing. Detecting community structure in dynamic networks has important theoretical and practical implications for understanding the intrinsic function of networks and predicting network behavior. However, the majority of existing dynamic community detection methods adopt shallow models, which have limited ability to excavate complex non-linear structures and tend to generate undesirable community structures. In order to obtain an accurate and robust community structure in dynamic networks, we are inspired by network representation learning and utilize the deep learning to detect evolving communities in dynamic networks. In this paper, we propose a novel dynamic community detection method by fusing Deep Learning and Evolutionary Clustering (DLEC). This work attempts to combine deep learning and evolutionary clustering into a unified framework. First, we propose a matrix construction strategy to fully reveal the inherent community structures via the underlying community memberships. Then, we develop a novel multi-layer deep autoencoder framework that consists of multiple non-linear functions to extract the latent deep representation of the dynamic network. Based on the evolutionary clustering framework, a graph regularization term is introduced to ensure the smoothness of the community evolution. Finally, we employ the K-means clustering algorithm on the low-dimensional network space to obtain the community structure. Extensive experimental results on synthetic and real-world networks show that the proposed DLEC algorithm can effectively detect high-quality communities in dynamic networks., (© 2024.

Two-dimensional (2D) inorganic nanomaterials have garnered extensive attention in the fabrication of inorganic nanofiltration membranes due to their unique structures and properties. In this study, we developed a facile process for fabricating large-scale ultrahydrophilic nanofiltration membranes using layered titanate H 1.07 Ti 1.73 O 4 · n H 2 O nanosheets (HT-ns). A drying deposition process was used to fabricate HT-ns membranes on a poly(tetrafluoroethylene) (TF) substrate. To enhance the bonding strength between the substrate and the deposited HT-ns membrane, the substrate surface was modified with a Cu 2+ -adsorbed silane monomolecular layer, connecting a negatively charged HT-ns membrane and a positively charged substrate surface. The fabricated HT-ns membrane exhibited an excellent rejection performance for inorganic salts and dye molecules. The ultrahydrophilicity of HT-ns membrane with a low water contact angle of 31° results in an ultrafast water permeance, which is approximately 6 times higher than that of a simple graphene-based nanofiltration membrane. The results open a new avenue to a new category of ultrahydrophilic nanofiltration membranes.

Cow milk protein allergy (CMPA) is a significant health concern characterized by adverse immune reactions to cow milk proteins. Biomarkers for the accurate diagnosis and prognosis of CMPA are lacking. This study analyzed the clinical features of CMPA, and 16S RNA sequencing was used to investigate potential biomarkers through fecal microbiota profiling. Children with CMPA exhibit a range of clinical symptoms, including gastrointestinal (83% of patients), skin (53% of patients), and respiratory manifestations (26% of patients), highlighting the complexity of this condition. Laboratory analysis revealed significant differences in red cell distribution width (RDW) and inflammatory markers between the CMPA and control groups, suggesting immune activation and inflammatory responses in CMPA. Microbial diversity analysis revealed higher specific diversity indices in the CMPA group compared with those in control group, with significant differences at the genus and species levels. Bacteroides were more abundant in the CMPA group, whereas Bifidobacterium, Ruminococcus, Faecalibacterium, and Parabacteroides were less abundant. The control group exhibited a balanced microbial profile, with a predominant presence of Bifidobacterium bifidum and Akkermansia muciniphila. The significant abundance of Bifidobacterium in the control group (23.19% vs 9.89% in CMPA) was associated with improved growth metrics such as height and weight, suggesting its potential as a probiotic to prevent CMPA and enhance gut health. Correlation analysis linked specific microbial taxa such as Coprococcus and Bifidobacterium to clinical parameters such as family allergy history, weight and height, providing insights into CMPA pathogenesis. Significant differences in bacterial abundance suggested diagnostic potential, with a panel of 6 bacteria achieving high predictive accuracy (area under curve (AUC) = 0.8708). This study emphasizes the complex relationship between the gut microbiota and CMPA, offering valuable insights into disease mechanisms and diagnostic strategies., (© 2024, The Authors.

Objectives: Helping residents select nutrient-dense foods is a strategy to improve their diet quality. However, communication based on the nutrient-dense foods as a positive attribute has not been widely used in nutritional education. This study aimed to develop an educational tool based on the picture and guidance of "Chinese food guide pagoda (2022) ", extend it with the concept of nutrient density, and investigate its acceptance by Chinese residents from Henan province., Methods: Three examples (one-day diet with high, medium, and low nutrient-rich food (NRF) 9.2 score, an indicator for evaluating dietary nutrient density) were designed for developing a dietary nutrient density educational tool. A self-designed questionnaire was conducted to investigate the acceptance of the "dietary nutrient density educational tool" among college students from Henan province on the basis of the theory of planned behavior., Results: Among the three one-day diets used in the tool, with the decrease in the NRF9.2 score, the energy intake increased from 1686 kcal to 2363 kcal, the dietary fat-to-energy ratio increased from 28 to 42%, and the mean adequacy ratio (MAR) decreased from 0.97 to 0.87. A total of 851 college students completed the acceptance questionnaire. The average score of the acceptance was 4.07, with a total score of 5. This study showed that resident's intention to use the tool was correlated with family residence, perceptual behavior control, and subjective norms. These three factors accounted for 83.5% of the variation in behavior intention., Conclusion: To encourage residents choosing healthier foods, a dietary nutrient density educational tool was developed to expanding the current instructional tool-the Chinese food guide pagoda (2022). The acceptance questionnaire survey revealed that residents had good acceptance of the tool, and family residence, perceptual behavior control, subjective norms may strongly contribute to their acceptance and the intention to use of the tool., (© 2024.

Context: Turner syndrome (TS) is characterized by a partial or complete absence of the second X chromosome in female. Here, patients with Xp deletion involving SHOX haploinsufficiency caused by unbalanced X-autosome translocations were discussed and considered as TS variants., Objective: This work aimed to expand the current knowledge of TS and unbalanced X-autosome translocations and to suggest the definition, clinical characteristics, diagnosis workflow and growth hormone (GH) treatment strategy of TS and its variants., Methods: A 9.0-year-old patient of TS variant with tall target height (+2.03SD) but low height velocity (3.6cm/y) and height (-1.33SD) was evaluated as an example. Patients similar to the index patient were systematically searched in MEDLINE and EMBASE and summarized. A diagnosis workflow and scores for risk assessment of GH treatment (RiGHT scores) for TS variants were also proposed in this study., Results: According to the diagnosis workflow, the girl's karyotype was confirmed as 46,X,der(X)t(X;7)(p11.3; p14.1), and was evaluated as low risk using RiGHT scores. After 2-year GH treatment, she had a significantly increased height (-0.94SD). Moreover, a total of 13 patients from 10 studies were summarized, characterized as short stature, growth retardation, craniofacial abnormalities, disorders of intellectual development, and psychomotor delays. Risk assessment of GH treatment using RiGHT scores were also applied in these 13 patients., Conclusion: The patients with Xp deletion caused by unbalanced X-autosome translocations should be considered as TS variants. The diagnosis workflow and RiGHT scores is a useful approach for clinicians in addressing complex cases of TS variants with GH treatment in clinical practice., (© The Author(s) 2024.

Podocan, a small leucine-rich repeat protein, is expressed in HIV-associated nephropathy, the cardiovascular system, and smooth muscle. Studies have linked PODN and PODNL to cancers such as osteosarcoma, glioma, and stomach cancer. Research has primarily focused on podocan's role in renal podocytes, injured smooth muscle cells, and various tumor cells. Bioinformatics studies have examined the role of PODN as a biomarker in tumors. Our research summarizes the modulatory role of podocan in smooth muscle and tumor proliferation through its suppression of cell proliferation and promotion of cell differentiation via various signaling pathways, including Wnt/β-catenin, TGF-β, and Akt/mTOR. We aim to provide a comprehensive overview of PODN's involvement in smooth muscle, cardiovascular system, and tumors by integrating current and past research. This review aims to enhance understanding and inform in the diagnosis, prognosis, and treatment of various diseases., 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 The Authors.

Throughout history, various odors have been harnessed to invigorate or relax the mind. The mechanisms underlying odors' diverse arousal effects remain poorly understood. We conducted five experiments (184 participants) to investigate this issue, using pupillometry, electroencephalography, and the attentional blink paradigm, which exemplifies the limit in attentional capacity. Results demonstrated that exposure to citral, compared to vanillin, enlarged pupil size, reduced resting-state alpha oscillations and alpha network efficiency, augmented beta-gamma oscillations, and enhanced the coordination between parietal alpha and frontal beta-gamma activities. In parallel, it attenuated the attentional blink effect. These effects were observed despite citral and vanillin being comparable in perceived odor intensity, pleasantness, and nasal pungency, and were unlikely driven by semantic biases. Our findings reveal that odors differentially alter the small-worldness of brain network architecture, and thereby brain state and arousal. Furthermore, they establish arousal as a unique dimension in olfactory space, distinct from intensity and pleasantness., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 The Authors.

Background: Rising prostate-specific antigen (PSA) levels following radical prostatectomy are indicative of a poor prognosis, which may associate with periprostatic adipose tissue (PPAT). Accordingly, we aimed to construct a dynamic online nomogram to predict tumor short-term prognosis based on 18 F-PSMA-1007 PET/CT of PPAT., Methods: Data from 268 prostate cancer (PCa) patients who underwent 18 F-PSMA-1007 PET/CT before prostatectomy were analyzed retrospectively for model construction and validation (training cohort: n = 156; internal validation cohort: n = 65; external validation cohort: n = 47). Radiomics features (RFs) from PET and CT were extracted. Then, the Rad-score was constructed using logistic regression analysis based on the 25 optimal RFs selected through maximal relevance and minimal redundancy, as well as the least absolute shrinkage and selection operator. A nomogram was constructed to predict short-term prognosis which determined by persistent PSA., Results: The Rad-score consisting of 25 RFs showed good discrimination for classifying persistent PSA in all cohorts (all P < 0.05). Based on the logistic analysis, the radiomics-clinical combined model, which contained the optimal RFs and the predictive clinical variables, demonstrated optimal performance at an AUC of 0.85 (95% CI: 0.78-0.91), 0.77 (95% CI: 0.62-0.91) and 0.84 (95% CI: 0.70-0.93) in the training, internal validation and external validation cohorts. In all cohorts, the calibration curve was well-calibrated. Analysis of decision curves revealed greater clinical utility for the radiomics-clinical combined nomogram., Conclusion: The radiomics-clinical combined nomogram serves as a novel tool for preoperative individualized prediction of short-term prognosis among PCa patients., (© 2024.

Dihydroxyaluminum aminoacetate, heavy magnesium carbonate, and aspirin tablets is a new combined aspirin preparation, each containing aspirin (81 mg), dihydroxyaluminum aminoacetate (11 mg), and heavy magnesium carbonate (22 mg). This study was conducted to evaluate the pharmacokinetic (PK) and bioequivalence in healthy Chinese subjects. This randomized, open-label, single-dose, 2-sequence, and 2-period crossover study included 78 healthy volunteers (fasting, n = 36; postprandial, n = 42). Blood samples were collected for PK analysis. Aspirin and salicylic acid concentrations in human plasma were determined by liquid chromatography-tandem mass spectrometry. Safety and tolerability were monitored. There were no significant differences between the test and reference formulations in maximum plasma concentration, area under the plasma concentration-time curve (AUC) from time 0 to time t, or AUC from time 0 to infinity. The 90% confidence intervals of the test and reference formulations of maximum plasma concentration, AUC from time 0 to time t, and AUC from time 0 to infinity were within the acceptable range (80%-125%) under fasting and postprandial conditions. All adverse events were mild and no serious adverse events were observed in the study. Both compounds were well tolerated in healthy Chinese volunteers., (© 2024, The American College of Clinical Pharmacology.)

Climate change mitigation is a pressing global challenge that requires reducing CO 2 emissions without hindering economic growth. Using an extended Kaya identity, Logarithmic Mean Divisia Index (LMDI), and Tapio decoupling indicator, this paper investigates the spatio-temporal variations, drivers, and decoupling of CO 2 emissions from economic growth in 150 countries from 1990 to 2019, considering regional disparities and income-based inequalities. The findings reveal increasing CO 2 emissions between 1990 and 2019, with notable fluctuations in certain 5-year intervals. CO 2 emission growth varied significantly by region, with countries like China, the USA, India, and Japan experiencing rapid increases. Economic growth emerged as the primary driver of CO 2 emission growth, and its impact strengthened over time. Population growth also contributed significantly to CO 2 emissions, particularly in middle- and low-income countries. The study identifies energy and carbon intensity as crucial mitigating factors that weaken CO 2 emissions, offering hope for effective climate change mitigation. Furthermore, the degree of decoupling between economic growth and CO 2 emissions varied among countries in the same region, with high-income countries demonstrating stronger decoupling compared to upper-middle-income countries, which accounted for 71% of global CO 2 emission increase. These findings underline the imperative of accounting for income levels and regional differences in formulating CO 2 emission mitigation strategies. Also, the study emphasizes the pressing necessity for cohesive global coordination to facilitate the transition toward a low-carbon economy. Such collaborative endeavors are paramount in our collective pursuit to combat climate change effectively, safeguarding the well-being and sustenance of our planet for future generations. As policymakers, it is imperative to integrate these insights into decision-making processes to chart a sustainable and resilient course forward., (© 2023.

Background: Neoadjuvant immunotherapy has ushered in a new era of perioperative treatment for resectable non-small cell lung cancer (NSCLC). However, large-scale data for verifying the efficacy and optimizing the therapeutic strategies of neoadjuvant immunochemotherapy in routine clinical practice are scarce., Methods: NeoR-World (NCT05974007) was a multicenter, retrospective cohort study involving patients who received neoadjuvant immunotherapy plus chemotherapy or chemotherapy alone in routine clinical practice from 11 medical centers in China between January 2010 and March 2022. Propensity score matching was performed to address indication bias., Results: A total of 408 patients receiving neoadjuvant immunochemotherapy and 684 patients receiving neoadjuvant chemotherapy were included. The pathologic complete response (pCR) and major pathologic response (MPR) rates of the real-world neoadjuvant immunochemotherapy cohort were 32.8% and 58.1%, respectively. Notably, patients with squamous cell carcinoma exhibited significantly higher pCR and MPR rates than those with adenocarcinoma (pCR, 39.2% vs 16.5% [P < .001]; MPR, 66.6% vs 36.5% [P < .001]), whereas pCR and MPR rates were comparable among patients receiving different neoadjuvant cycles. In addition, the 2-year rates of disease-free survival (DFS) and overall survival (OS) rate were 82.0% and 93.1%, respectively. Multivariate analyses identified adjuvant therapy as an independent prognostic factor for DFS (hazard ratio [HR], 0.51; 95% confidence interval [CI], 0.29-0.89; P = .018) and OS (HR, 0.28; 95% CI, 0.13-0.58; P < .001). A significantly longer DFS with adjuvant therapy was observed in patients with non-pCR or 2 neoadjuvant cycles. We observed significant benefits in pCR rate (32.4% vs 6.4%; P < .001), DFS (HR, 0.50; 95% CI, 0.38-0.68; P < .001) and OS (HR, 0.61; 95% CI, 0.40-0.94; P = .024) with immunotherapy plus chemotherapy compared to chemotherapy alone both in the primary propensity-matched cohort and across most key subgroups., Conclusions: The study validates the superior efficacy of neoadjuvant immunochemotherapy over chemotherapy alone for NSCLC. Adjuvant therapy could prolong DFS in patients receiving neoadjuvant immunochemotherapy, and patients with non-pCR or those who underwent 2 neoadjuvant cycles were identified as potential beneficiaries of adjuvant therapy., Competing Interests: Conflict of Interest Statement The authors reported no conflicts of interest.

The journey of cancer development is a multifaceted and staged process. The array of treatments available for cancer varies significantly, dictated by the disease's type and stage. Cancer-associated fibroblasts (CAFs), prevalent across various cancer types and stages, play a pivotal role in tumor genesis, progression, metastasis, and drug resistance. The strategy of concurrently targeting cancer cells and CAFs holds great promise in cancer therapy. In this review, we focus intently on CAFs, delving into their critical role in cancer's progression. We begin by exploring the origins, classification, and surface markers of CAFs. Following this, we emphasize the key cytokines and signaling pathways involved in the interplay between cancer cells and CAFs and their influence on the tumor immune microenvironment. Additionally, we examine current therapeutic approaches targeting CAFs. This article underscores the multifarious roles of CAFs within the tumor microenvironment and their potential applications in cancer treatment, highlighting their importance as key targets in overcoming drug resistance and enhancing the efficacy of tumor therapies., (© 2024.
