To expand the detection capabilities of silicon (Si)-based photodetector and address key scientific challenges such as low light absorption efficiency and short carrier lifetime in Si-based graphene photodetector. This work introduces a novel Si-based Schottky coupled structure by in situ growth of 3D-graphene and molybdenum disulfide quantum dots (MoS 2 QDs) on Si substrates using chemical vapor deposition (CVD) and plasma-enhanced chemical vapor deposition (PECVD) techniques. The findings validate the "dual-enhanced absorption" effect, enhancing the understanding of the mechanisms that improve optoelectronic performance. The synergistic effect of 3D-graphene's natural nano-resonant cavity and MoS 2 QDs enhances light absorption efficiency and extends carrier lifetime. Introducing MoS 2 QDs broadens and intensifies the built-in electric field, promoting the separation of photogenerated electrons and holes. The photodetector exhibits a wideband light response in the wavelength range of 380-2200 nm. It stably outputs photocurrent under high-frequency (1 kHz) modulated laser (2200 nm), with a responsivity (R) of 40 mA W -1 and detectivity (D * ) of 1.15 × 10 9 Jones. Photodetectors show the ability to process and encrypt complex binary signals and achieve versatility in "AND" gate and "OR" gate logic operations, as well as image sensing (240 × 200 pixels)., (© 2024 Wiley‐VCH GmbH.)

Evidence suggests that exposure to organophosphate pesticides increases the risk of neurodegenerative diseases, but the mechanisms remain unclear. This study investigated the effects of malathion on Alzheimer's disease (AD)-like symptoms at environmentally relevant concentrations using wild-type (WT) and APP/PS1 transgenic mouse models. Results showed that malathion exposure induced AD-like cognitive impairment, amyloid-β (Aβ) accumulation, and neuroinflammation in WT mice, with worsened symptoms in APP/PS1 mice. Mechanistic studies revealed that malathion induced AD-like gut microbiota dysbiosis (reduced Lactobacillus and Akkermansia , and increased Dubosiella ), causing gut barrier impairment and tryptophan metabolism disruptions. This resulted in a significant increase in indole derivatives and activation of the colonic aryl hydrocarbon receptor (AhR), promoting the kynurenine (KYN) pathway while inhibiting the serotonin (5-HT) pathway. Increased neurotoxic KYN metabolites (3-hydroxykynurenine and quinolinic acid) triggered gut and systemic inflammation, upregulating hippocampal IL-6 and IL-1β mRNA levels and thereby causing neuroinflammation. Gut tryptophan metabolism disruptions caused hippocampal neurotransmitter imbalances, reducing the levels of 5-HT and its derivatives. These effects promoted AD progression in both WT and APP/PS1 mice. This study highlights the crucial role of the microbiota-gut-brain axis in AD-like cognitive impairment induced by malathion exposure, providing insights into the neurodegenerative disease risks posed by organophosphate pesticides.

Background: Transglutaminase (TGase) is a heat-resistant biocatalyst with strong catalytic activity, which functions effectively under moderate temperature and pH conditions, and is used widely in protein cross-linking and recombination. Transglutaminase cross-linking is a novel and specific modification method for black bean protein isolate (BBPI). This article investigates the effect of transglutaminase cross-linking on the structure and emulsification performance of heated BBPI., Results: Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that heated BBPI with TGase had a higher molecular weight than heated BBPI without TGase, and the protein bands widened with increasing enzyme activity, indicating that TGase cross-linking promoted protein molecule aggregation. A high molecular weight polymer can better stabilize the oil-water interface, preventing the emulsion from layering. Fourier transform infrared (FTIR) spectroscopy showed that the α-helix content decreased from 15.64% to 13.75%, and the β-sheet content increased from 48.13% to 54.08%. The decrease in α-helix content and increase in β-sheet content could make the structure more stable and improve the emulsifying properties of heated BBPI. When TGase was 20 U g -1 , the protein emulsification activity index (EAI) reached its highest value of 1.87 m 2  g -1 , and the emulsification stability index (ESI) value was 0.27 min (P < 0.05); these figures were 0.19 m 2  g -1 , and 0.07 min higher, respectively, than in the sample without added TGase., Conclusion: In summary, transglutaminase cross-linking has a positive effect on the structure and emulsification performance of heated BBPI and can be used as an effective method for BBPI modification. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)

Middle East respiratory syndrome coronavirus (MERS-CoV) and the pangolin MERS-like coronavirus MjHKU4r-CoV-1 employ dipeptidyl peptidase 4 (DPP4) as an entry receptor. MjHKU4r-CoV-1 could infect transgenic mice expressing human DPP4. To understand the mechanism of MjHKU4r-CoV-1 entry into cells, we determined the crystal structures of the receptor binding domain (RBD) of MjHKU4r-CoV-1 spike protein bound to human DPP4 (hDPP4) and Malayan pangolin DPP4 (MjDPP4), respectively. The overall hDPP4-binding mode of MjHKU4r-CoV-1 RBD is similar to that of MERS-CoV RBD. MjHKU4r-CoV-1 RBD shows higher binding affinity to hDPP4 compared to the bat MERS-like coronavirus Ty-BatCoV-HKU4. Via swapping residues between MjHKU4r-CoV-1 RBD and Ty-BatCoV-HKU4 RBD, we identified critical determinants on MjHKU4r-CoV-1 that are responsible for virus usage of hDPP4. Our study suggests that MjHKU4r-CoV-1 is more adapted to the human receptor compared to the bat HKU4 coronavirus and highlights the potential of virus emergence into the human population., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yang et al.

(1) Background: Chitons (Mollusca, Polyplacophora) are relatively primitive species in Mollusca that allow the study of biomineralization. Although mitochondrial genomes have been isolated from Polyplacophora, there is no genomic information at the chromosomal level; (2) Methods: Here we report a chromosome-level genome assembly for Acanthochiton rubrolineatus using PacBio (Pacific Biosciences, United States) reads and high-throughput chromosome conformation capture (Hi-C) data; (3) Results: The assembly spans 1.08 Gb with a contig N50 of 3.63 Mb and 99.97% of the genome assigned to eight chromosomes. Among the 32,291 predicted genes, 76.32% had functional predictions. The divergence time of Brachiopoda and Mollusca was ~550.8 Mya (million years ago), and that of A. rubrolineatus and other mollusks was ~548.5 Mya; (4) Conclusions: This study not only offers high-quality reference sequences for the Acanthochiton rubrolineatus genome, but also establishes groundwork for investigating the mechanisms of Polyplacophora biomineralization and its evolutionary history. This research will aid in uncovering the genetic foundations of molluscan adaptations across diverse environments.

Background: Reproduction is the basis of insect population growth and evolution, and encompasses ovarian development, reproductive behavior, and fecundity. Bactrocera dorsalis is a globally significant agricultural pest that is subject to quarantine, with mated females that can lay over 3000 eggs. The post-transcriptional regulation of ovarian development remains unclear. Here, miR-31b is shown to be involved in regulating Bactrocera dorsalis ovarian development., Results: CRISPR/Cas9 was used to generate miR-31b loss-of-function mutations in Bactrocera dorsalis. The removal of miR-31b resulted in severely impaired ovarian development in adults, with phenotypes that included dramatically reduced egg production and hatching rates. The relationship between miR-31b and its target gene arylsulfatase B (ARSB) was subsequently identified using the methods of bioinformatics, transcriptomic sequencing, quantitative polymerase chain reaction (qPCR), RNA pull-down and dual-luciferase reporter assay. Finally, miR-31b was confirmed to bind the target gene arylsulfatase B to affect metabolism and thereby further hindered ovarian development of Bactrocera dorsalis., Conclusion: Overall, these results provide new insights into molecular mechanisms at the post-transcriptional level in regulating ovarian development and insect reproduction, consequently providing potential targets to control arthropod pests through the reproductive strategy. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)

The distribution characteristics and risk levels of PAHs in surface sediment in the Honghai Bay of China are studied in this paper. The results showed that the concentration of total PAHs in this area ranged from 100.65 ng·g -1 to 241.31 ng·g -1 , with an average concentration of 158.83 ng·g -1 . The tricyclic PAHs were the main components in the detected PAHs. PAH pollution levels in this region were low and moderate as compared with adjacent areas. Traceability results showed that the sediment PAHs mainly originate from coal and biomass combustion. PAHs concentrations at some stations were above the Environmental Quality Reference Level. The PAHs toxicity and ecological risk level in surface sediments in the area was determined to be low to moderate by toxicity equivalence testing and risk entropy value assessment., 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.

Although coronaviruses use diverse receptors, the characterization of coronaviruses with unknown receptors has been impeded by a lack of infection models 1,2 . Here we introduce a strategy to engineer functional customized viral receptors (CVRs). The modular design relies on building artificial receptor scaffolds comprising various modules and generating specific virus-binding domains. We identify key factors for CVRs to functionally mimic native receptors by facilitating spike proteolytic cleavage, membrane fusion, pseudovirus entry and propagation for various coronaviruses. We delineate functional SARS-CoV-2 spike receptor-binding sites for CVR design and reveal the mechanism of cell entry promoted by the N-terminal domain-targeting S2L20-CVR. We generated CVR-expressing cells for 12 representative coronaviruses from 6 subgenera, most of which lack known receptors, and show that a pan-sarbecovirus CVR supports propagation of a propagation-competent HKU3 pseudovirus and of authentic RsHuB2019A 3 . Using an HKU5-specific CVR, we successfully rescued wild-type and ZsGreen-HiBiT-incorporated HKU5-1 (LMH03f) and isolated a HKU5 strain from bat samples. Our study demonstrates the potential of the CVR strategy for establishing native receptor-independent infection models, providing a tool for studying viruses that lack known susceptible target cells., (© 2024.

Efficient DNA replication requires highly coordinated programs for the timely recruitment of protein complexes to DNA replication forks. Defects in this process result in replication stress, which in turn activates cell cycle checkpoints, suppresses cell proliferation and induces apoptosis. In response to persistent cell growth signals that speed up DNA replication processes, cells accelerate the recruitment of DNA replication proteins to avoid DNA replication stress. The mechanisms by which cell growth signals induce processes to facilitate the recruitment of DNA replication proteins onto the replication sites remain unclear. Here, we report that the epidermal growth factor receptor (EGFR) phosphorylates heat shock protein 70 (HSP70) for DNA replication. Such a modification promotes nuclear localization and chromatin association of HSP70, which interacts with the DNA replication coordinator, proliferating cell nuclear antigen (PCNA). HSP70 subsequently facilitates the loading of PCNA onto chromatin. Knockdown or chemical inhibition of HSP70 suppresses PCNA association with chromatin and impairs DNA synthesis and Okazaki fragment maturation, leading to replicative DNA double-strand breaks and apoptosis. Furthermore, chemical inhibition of HSP70 potentiates EGFR-tyrosine kinase inhibitor-induced tumor reduction in vivo. This work expands our understanding of oncogenesis-induced DNA replication processes and provides a foundation for improved treatments for EGFR-mutated lung cancer by simultaneously targeting HSP70., (© The Author(s) 2024.

Despite the significant potential of RNA-cleaving DNAzymes for gene regulation, their application is limited by low therapeutic efficacy and lack of cell-specific control. Here, a DNAzyme-based nanohybrid designed for ultrasound (US)-controlled, enzyme-activatable mRNA regulation is presented, enabling tumor cell-selective combination therapy. The nanohybrid is constructed by coordination-directed self-assembly of an enzymatically-triggerable therapeutic DNAzyme (En-Dz) and natural sonosensitizer hemoglobin (Hb). Controlled US exposure induces reactive oxygen species generation from Hb units, which not only facilitates efficient endosomal escape of En-Dz, but also promotes the translocation of specific enzyme from the nucleus to the cytoplasm, thereby enhancing gene regulation efficacy. Notably, the enzyme-triggered, spatiotemporally-controlled activation of En-Dz's catalytic activity results in enhanced cancer-cell selectivity in the therapeutic treatment. Furthermore, the combination of enzyme-activated mRNA regulation and sonodynamic therapy significantly enhances anti-tumor efficacy both in vitro and in vivo. This work highlights the potential of integrating a sonodynamic strategy to overcome the current limitations of DNAzyme-based gene regulators, providing a spatiotemporally-controlled approach for precise tumor treatment., (© 2024 Wiley‐VCH GmbH.)

Chemical-caused reproductive dysfunction has emerged as a global public health concern. This study investigated the adverse effects of the organophosphorus pesticide malathion on reproductive function in adolescent male mice at environmentally relevant concentrations. The results indicated that eight-week malathion exposure reduced testis weight, caused sex and thyroid hormone disorders, and induced testicular spermatogenic epithelium damage and oxidative stress. Testicular RNA sequencing indicated that malathion significantly affected testicular energy metabolism, hypoxia-inducible factor 1 (HIF-1) signaling, and steroid hormone biosynthesis pathways. Malathion significantly increased the gene and protein expression of HIF-1α by upregulating key genes in the mitogen-activated protein kinase (MAPK) pathway (Map2k2, Mapk3, and Eif4e2) and the phosphatidylinositol 3-kinase (PI3K) pathway (Pik3r2 and Akt1). Furthermore, malathion downregulated HIF-1α degradation-regulating genes while upregulating anaerobic metabolism and inflammation-related genes, thereby inhibiting normoxia and promoting hypoxia processes. Testicular hypoxia subsequently induced steroid hormone biosynthesis disorders and spermatogenesis dysfunction. Molecular docking verified that malathion interfered with HIF-1α and steroid hormone synthases (CYP11A1, CYP17A1 and CYP19A1) by forming hydrogen bonds and hydrophobic interactions with these proteins. This study presents the first evidence that malathion triggers spermatogenesis dysfunction in mice through activating the HIF-1/MAPK/PI3K pathway, providing a comprehensive understanding of the reproductive toxicity risks associated with organophosphorus pesticides., 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.

This study investigated the occurrence status, sources, and risk assessment of polycyclic aromatic hydrocarbons (PAHs) in sediments from three typical mangrove areas in Guangxi Province, China. Results showed that the PAH content in the three studied regions ranged from 39.76 ng·g -1 to 164.93 ng·g -1 , and the average concentration was 92.87 ng·g -1 . The PAHs that were detected were mainly 3-ring and 4-ring. The source of PAHs, as traced by the diagnostic ratio method and principal component analysis, was mainly from combustion. The toxicity risk assessment showed that the content of all PAHs was lower than the Effects Range Low (ERL), and the potential ecological risk was low. The toxicity equivalent (TEQ BaP ) content ranged from 4.75 ng·g -1 to 19.20 ng·g -1 , with an average of 12.08 ng·g -1 . Overall, the ecological risk of PAHs in mangrove sediments in Guangxi is considered low., Competing Interests: Declaration of competing interest All authors declare there are no conflicts of interest regarding the publication of this paper., (Copyright © 2024 Elsevier Ltd.

Background: Hypertrophic cardiomyopathy (HCM) is a common hereditary cardiomyopathy. Mavacamten, a first-in-class cardiac myosin inhibitor, is considered to be a specific drug for the treatment of HCM. This meta-analysis aimed to assess the efficacy and safety of mavacamten in patients with HCM., Methods: PubMed, Cochrane Library, Embase and Clinical Trials.gov databases were searched from inception to February 6, 2024 for randomized controlled trials (RCTs) which compared the efficacy and safety between mavacamten and placebo in treating HCM., Results: Six RCTs involving 732 patients were included in this meta-analysis. This meta-analysis showed that mavacamten improved the New York Heart Association (NYHA) function class [risk ratios (RR): 2.21, 95% confidence interval (CI): 1.48 to 3.30, p = 0.00001], Clinical Summary Score of the Kansas City Cardiomyopathy Questionnaire (KCCQ-CSS) scores [mean difference (MD): 9.33, 95% CI: 7.09 to 11.57, p < 0.00001] and composite functional end point (RR: 1.86, 95% CI: 1.25 to 2.78, p = 0.002). Meanwhile, mavacamten decreased N-terminal pro-B-type natriuretic peptide (NT-proBNP) (MD: -492.28, 95% CI: -611.55 to -373.02, p < 0.00001), cardiac troponin I (cTnI) (MD: -14.58, 95% CI: -26.98 to -2.17, p = 0.02) and Valsalva left ventricular outflow tract (LVOT) gradient (MD: -57.96, 95% CI: -82.15 to -33.78, p < 0.00001). The results for the incidence of ≥1 total emergent adverse event (TEAE) and ≥1 serious adverse event (SAE) showed that there was no significant difference between both groups (RR: 1.9, 95% CI: 0.97 to 1.24, p = 0.16) (RR: 1.06, 95% CI: 0.46 to 2.44, p = 0.90)., Conclusions: Mavacamten has great efficacy for the treatment of HCM. Meanwhile, mavacamten did not increase the incidence of adverse events or serious adverse events., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2024 The Author(s).

The construction of helical nanotubes based on chiral coordination polymers (CPs) is an intriguing but challenging task, which is important for the development of functional materials that combine macroscopic chirality with tube-related properties. Here, we selected a chiral europium phosphonate system, e. g., Eu(NO 3 ) 3 /R-,S-pempH 2 , and carried out a systematic work. By controlling the hydrothermal reaction conditions such as the pH value of the reaction mixture, the molar ratio and concentration of the reactants, we obtained block-like crystals of R/S-1 b, rod-like crystals of R/S-3 r, hollow superhelices of R/S-2 hh, and solid superhelices of R/S-4 sh. In the latter two cases, the chirality has been successfully transferred and amplificated from the molecular level to the macroscopic level. Interestingly, compounds R/S-2 hh and R/S-4 sh have the same chemical composition of Eu(R/S-pempH) 3 ⋅2H 2 O and show identical PXRD patterns, thus can be considered as the same material except for different morphologies. We further investigated their circularly polarized luminescence (CPL) properties and found that the hollow superhelix of R/S-2 hh had a larger dissymmetry factor than the solid superhelix of R/S-4 sh. This study not only provides the first example of hollow superhelices of chiral CPs, but also offers the possibility of modulating the chiroptical properties of CPs through morphological control., (© 2024 Wiley-VCH GmbH.)

Nucleases are a super family of enzymes that hydrolyze phosphodiester bonds present in genomes. They widely vary in substrates, causing differentiation in cleavage patterns and having a diversified role in maintaining genetic material. Through cellular evolution of prokaryotic to eukaryotic, nucleases become structure-specific in recognizing its own or foreign genomic DNA/RNA configurations as its substrates, including flaps, bubbles, and Holliday junctions. These special structural configurations are commonly found as intermediates in processes like DNA replication, repair, and recombination. The structure-specific nature and diversified functions make them essential to maintaining genome integrity and evolution in normal and cancer cells. In this article, we review their roles in various pathways, including Okazaki fragment maturation during DNA replication, end resection in homology-directed recombination repair of DNA double-strand breaks, DNA excision repair and apoptosis DNA fragmentation in response to exogenous DNA damage, and HIV life cycle. As the nucleases serve as key points for the DNA dynamics, cellular apoptosis, and cancer cell survival pathways, we discuss the efforts in the field in developing the therapeutic regimens, taking advantage of recently available knowledge of their diversified structures and functions., (© The Author(s) (2024).

The detection of gravitational waves has ushered in a new era of observing the universe. Quantum resource advantages offer significant enhancements to the sensitivity of gravitational wave observatories. While squeezed states for ground-based gravitational wave detection have received marked attention, the generation of squeezed states suitable for mid-to-low-frequency detection has remained unexplored. To address the gap in squeezed state optical fields at ultra-low frequencies, we report on the first direct observation of a squeezed vacuum field until Fourier frequency of 4 millihertz with the quantum noise reduction of up to 8.0 dB, by the employment of a multiple noise suppression scheme. Our work provides quantum resources for future gravitational wave observatories, facilitating the development of quantum precision measurement., (© 2024. The Author(s).)

Background: Acute coronary syndrome and atrial fibrillation are common cardiovascular diseases in elderly individuals. Patients with comorbidities face increased risks of bleeding and ischemia; however, there is a lack of prognostic models for quantifying these risks in this special population., Methods and Results: In this retrospective cohort study, 1851 patients (≥65 years old) with acute coronary syndrome and atrial fibrillation from 2 hospitals in China were included in the development cohort (1252 individuals) and 2 external validation cohorts (284 and 315 individuals). During 1-year follow-up, 96 Bleeding Academic Research Consortium type 3 or 5 bleeding events and 245 thromboembolic events were observed. In the development cohort, the concordance indexes for bleeding at 3, 6, and 12 mo ranged from 0.737 to 0.845 and for ischemia ranged from 0.723 to 0.777. The calibration curve and decision curve analysis indicated adequate calibration and clinical practicability. The concordance indexes varied from 0.679 to 0.809 in the validation cohorts. Subgroup analyses focusing on anticoagulant drugs and antithrombotic therapy were conducted, revealing similar discrimination and calibration. Kaplan-Meier curves demonstrated significant differences (log-rank P <0.001). Additionally, the models outperformed conventional models in concordance indexes, integrated discrimination improvement, and net reclassification improvement., Conclusions: Our study provides 2 robust prognostic models with easily available clinical factors for predicting bleeding and ischemia in elderly patients with acute coronary syndrome and atrial fibrillation. Furthermore, we provide online calculators to facilitate individualized risk evaluation and clinical decision-making., Registration: URL: www.chictr.org.cn/. Unique Identifier: ChiCTR2200067185.

ConspectusPorous metal phosphonate frameworks (PMPFs) as a subclass of metal-organic frameworks (MOFs) have promising applications in the fields of gas adsorption and separation, ion exchange and storage, catalysis, sensing, etc. Compared to the typical carboxylate-based MOFs, PMPFs exhibit higher thermal and water stability due to the strong coordination ability of the phosphonate ligands. Despite their robust frameworks, PMPFs account for less than 0.51% of the porous MOFs reported so far. This is because metal phosphonates are highly susceptible to the formation of dense layered or pillared-layered structures, and they precipitate easily and are difficult to crystallize. There is a tendency to use phosphonate ligands containing multiple phosphonate groups and large organic spacers to prevent the formation of dense structures and generate open frameworks with permanent porosity. Thus, many PMPFs are composed of chains or clusters of inorganic metal phosphonates interconnected by organic spacers. Using this feature, a wide range of metal ions and organic components can be selected, and their physical properties can be modulated. However, limited by the small number of PMPFs, there are still relatively few studies on the physical properties of PMPFs, some of which merely remain in the description of the phenomena and lack in-depth elaboration of the structure-property relationship. In this Account, we review the strategies for constructing PMPFs and their physical properties, primarily based on our own research. The construction strategies are categorized according to the number ( n = 1-4) of phosphonate groups in the ligand. The physical properties include proton conduction, electrical conduction, magnetism, and photoluminescence properties. Proton conductivity of PMPFs can be enhanced by increasing the proton carrier concentration and mobility. The former can be achieved by adding acidic groups such as -POH and/or introducing acidic guests in the hydrophilic channels. The latter can be attained by introducing conjugate acid-base pairs or elevating the temperature. Semiconducting PMPFs, on the other hand, can be obtained by constructing highly conjugated networks of coordination bonds or introducing large conjugated organic linkers π-π stacked in the lattice. In the case of magnetic PMPFs, long-range magnetic ordering occurs at very low temperatures due to very weak magnetic exchange couplings propagated via O-P-O and/or O(P) units. However, lanthanide compounds may be interesting candidates for single-molecule magnets because of the strong single-ion magnetic anisotropy arising from the spin-orbit coupling and large magnetic moments of lanthanide ions. The luminescent properties of PMPFs depend on the metal ions and/or organic ligands. Emissive PMPFs containing lanthanides and/or uranyl ions are promising for sensing and photonic applications. We conclude with an outlook on the opportunities and challenges for the future development of this promising field.

Costly third-party punishment (TPP) is an effective way to enforce fairness norms and promote cooperation. Recent studies have shown that the third party considers not only the proposer's suggested allocation but also the receiver's response to the allocation, which was typically ignored in traditional TPP studies when making punishment decisions. However, it remains unclear whether and how the varying unfair allocations and receivers' responses are integrated into third-party punishment. The current study addressed these issues at behavioral and electrophysiological levels by employing a modified third-party punishment task involving proposers' highly or moderately unfair allocations and the receivers' acceptance or rejection responses. At the behavioral level, participants punished proposers more often when receivers rejected relative to accepted unfair allocations. This effect was further modulated by the unfairness degree of allocations, indicated by a more pronounced rejection-sensitive effect when participants observed the moderately unfair offers. Electrophysiologically, when the receiver rejected the moderately unfair allocations, a stronger late-stage component P300/LPP, which was considered to be involved in allocations of attention resources, was found. Meanwhile, separated from the P300/LPP, the P200 associated with early attention capture demonstrated a rejection-sensitive effect. Together, in the costly TPP studies, the receiver is typically designated as passive and silent, and her/his responses to unfairness are conventionally ignored. However, our results indicate that except for the proposer's distribution behavior, the receiver's response does have an impact on third-party punishment in a way that interacts with the unfairness of allocations., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2024 The Authors.

Our comprehensive understanding of the multi-species ACE2 adaptiveness of sarbecoviruses remains elusive, particularly for those with various receptor binding motif (RBM) insertions/deletions (indels). Here, we analyzed RBM sequences from 268 sarbecoviruses categorized into four RBM indel types. We examined the ability of 20 representative sarbecovirus Spike glycoproteins (S) and derivatives in utilizing ACE2 from various bats and several other mammalian species. We reveal that sarbecoviruses with long RBMs (type-I) can achieve broad ACE2 tropism, whereas viruses with single deletions in Region 1 (type-II) or Region 2 (type-III) exhibit narrower ACE2 tropism. Sarbecoviruses with double region deletions (type-IV) completely lost ACE2 usage, which is restricted by clade-specific residues within and outside RBM. Lastly, we propose the evolution of sarbecovirus RBM indels and illustrate how loop lengths, disulfide, and residue determinants shape multi-species ACE2 adaptiveness. This study provides profound insights into the mechanisms governing ACE2 usage and spillover risks of sarbecoviruses., (© 2024. The Author(s).)

Metal-organic frameworks (MOFs) with kagomé lattice are attractive for their unique physical and chemical properties, but little attention has been paid to their catalytic properties. Herein, we report a 2D MOF based on a phosphonato-amino-carboxylate ligand (NaHL), i. e., [Na 0.33 Co(L)(CH 3 OH) 2 ](NO 3 ) 0.33 (2), which exhibits an unconventional kagomé lattice. The formation of this kagomé lattice is caused by the selective recognition of the NO 3 - anion by the phenolato group of L 2- as evidenced by theoretical calculations. Compound 2 can be utilized for the α-methoxymethylation and aminomethylation of aromatic ketones using methanol as a C1 source. Interestingly, compound 2 can be exfoliated in-situ into nanosheets with one-layer thickness under catalytic reaction conditions, which improves the catalytic efficiency. Based on the results of experiments and theoretical calculations, we proposed possible pathways for the catalytic reaction., (© 2024 Wiley-VCH GmbH.)

To explore the association between the severity of sleep-disordered breathing, different types of respiratory events, peripheral oxygen saturation (SpO 2 ), age and sleep stage on cerebral oxygen saturation (rSO 2 ) in children. We enrolled children aged 4-14 years who were treated for snoring or mouth breathing at the Sleep Center of Beijing Children's Hospital, from February 2022 to July 2022. All children completed polysomnography, and SpO 2 , rSO 2 , and heart rate (HR) were recorded synchronously. A total of 70 children were included, including 16 (22.9%) with primary snoring, 38 (54.3%) with mild obstructive sleep apnea (OSA), and 16 (22.9%) with moderate-to-severe OSA. There were no significant differences in the mean rSO 2 or minimum rSO 2 among the primary snoring, mild OSA, and moderate-to-severe OSA groups (all p > 0.05). A total of 1119 respiratory events were included in the analysis. Regardless of the type of respiratory event, rSO 2 and HR changes occur prior to fluctuations in SpO 2 . A mixed-effects model showed that ΔrSO 2 was positively correlated with ΔSpO 2 , duration of respiratory event, mixed and obstructive apnea, central apnea, while negatively correlated with age and rapid eye movement (REM) sleep stage (all p < 0.05). Larger rSO 2 fluctuations were impacted by a greater ΔSpO 2 , longer duration of respiratory events, younger age, apnea-related respiratory events and non-REM sleep stage. Thus, sleep disordered breathing in younger children warrants more attention. More research is needed to determine whether REM sleep has special protective effects on rSO 2 ., (© 2024 European Sleep Research Society. Published by John Wiley & Sons Ltd.)

A novel cooperative pseudo[3]rotaxane system was successfully constructed by the inclusion complexation of two identical amine naphthotubes with a bis-pyridinium/isoquinolinium guest. Single crystal structure analysis revealed that weak C sp 3 -H⋯O hydrogen bonds between the two hosts are responsible for the positive cooperativity during the formation of pseudo[3]rotaxanes. Moreover, intermolecular charge-transfer interactions between the electron-rich host and the electron-poor guests were observed. The pseudo[3]rotaxanes showed pH-controllable association/dissociation processes with naked-eye color changes in solution.

As the primary grain crop in China, wheat holds a significant position in the country's agricultural production, circulation, consumption, and various other aspects. However, the presence of imperfect grains has greatly impacted wheat quality and, subsequently, food security. In order to detect perfect wheat grains and six types of imperfect grains, a method for the fast and non-destructive identification of imperfect wheat grains using hyperspectral images was proposed. The main contents and results are as follows: (1) We collected wheat grain hyperspectral data. Seven types of wheat grain samples, each containing 300 grains, were prepared to construct a hyperspectral imaging system for imperfect wheat grains, and visible near-infrared hyperspectral data from 2100 wheat grains were collected. The Savitzky-Golay algorithm was used to analyze the hyperspectral images of wheat grains, selecting 261 dimensional effective hyperspectral datapoints within the range of 420.61-980.43 nm. (2) The Successive Projections Algorithm was used to reduce the dimensions of the 261 dimensional hyperspectral datapoints, selecting 33 dimensional hyperspectral datapoints. Principal Component Analysis was used to extract the optimal spectral wavelengths, specifically selecting hyperspectral images at 647.57 nm, 591.78 nm, and 568.36 nm to establish the dataset. (3) Particle Swarm Optimization was used to optimize the Support Vector Machines model, Convolutional Neural Network model, and MobileNet V2 model, which were established to recognize seven types of wheat grains. The comprehensive recognition rates were 93.71%, 95.14%, and 97.71%, respectively. The results indicate that a larger model with more parameters may not necessarily yield better performance. The research shows that the MobileNet V2 network model exhibits superior recognition efficiency, and the integration of hyperspectral image technology with the classification model can accurately identify imperfect wheat grains.

Deutenzalutamide is a new molecular entity androgen receptor antagonist. The primary aim of this study was to develop a population pharmacokinetic model of deutenzalutamide and evaluate effects of intrinsic and extrinsic factors on pharmacokinetics. A nonlinear mixed-effects modeling approach was performed to develop the population pharmacokinetic of deutenzalutamide using data from 1 Phase I trial of deutenzalutamide. Goodness-of-fit plots, prediction-corrected visual predictive check, and bootstrap analysis were carried out to evaluate the final model. Simulation for the developed model was used to evaluate the covariate effects on the pharmacokinetics of deutenzalutamide. A 2-compartment model with first-order absorption and elimination from the central compartment was established for deutenzalutamide. The final covariate included body weight on peripheral compartment volume. This is the first research developing the population pharmacokinetic model of deutenzalutamide in patients with metastatic castration-resistant prostate cancer, and it is expected to support the future clinical administration of deutenzalutamide., (© 2024 The Author(s).

This study aimed to demonstrate the clinical outcomes of granulocyte colony-stimulating factor (G-CSF)/antithymocyte globulin (ATG), posttransplantation cyclophosphamide (PTCy) and PTCy combined with lowdose ATG (PTCy with ATGlow)-based haploidentical transplantation protocols in patients with haematologic malignancies. The comparisons were conducted via propensity score matching (PSM) analysis to balance the basic characteristics among different groups and were based on the transplantation data reported to the Chinese Bone Marrow Transplantation Registry Group (CBMTRG) from January 2020 to December 2022. For each patient in the PTCy or PTCy with ATGlow group, patients (at a 1:2 ratio) from the GCSF/ ATG group were selected. In total, the PTCy group (n=122) was matched with G-CSF/ATG Group 1 (n=230), and the PTCy+ATGlow group (n=123) was matched with G-CSF/ATG Group 2 (n=226). Compared with those in the PTCy group, the incidences of 28-day neutrophil engraftment (P=0.005), 100- day platelet engraftment (P=0.002), median time to neutrophil engraftment (P.

Emerging evidence suggests that transforming growth factor β1 (TGFβ1) can inhibit angiogenesis, contradicting the coexistence of active angiogenesis and high abundance of TGFβ1 in the tumor microenvironment. Here, we investigated how tumors overcome the anti-angiogenic effect of TGFβ1. TGFβ1 treatment suppressed physiological angiogenesis in chick chorioallantoic membrane and zebrafish models but did not affect angiogenesis in mouse hepatoma xenografts. The suppressive effect of TGFβ1 on angiogenesis was recovered in mouse xenografts by a hypoxia-inducible factor 1α (HIF1α) inhibitor. In contrast, a HIF1α stabilizer abrogated angiogenesis in zebrafish, indicating that hypoxia may attenuate the anti-angiogenic role of TGFβ1. Under normoxic conditions, TGFβ1 inhibited angiogenesis by upregulating anti-angiogenic factor thrombospondin 1 (TSP1) in endothelial cells (ECs) via TGFβ type I receptor (TGFβR1)-SMAD2/3 signaling. In a hypoxic microenvironment, HIF1α induced microRNA-145 (miR145) expression; miR145 abolished the inhibitory effect of TGFβ1 on angiogenesis by binding and repressing SMAD2/3 expression and subsequently reducing TSP1 levels in ECs. Primary ECs isolated from human hepatocellular carcinoma (HCC) displayed increased miR145 and decreased SMAD3 and TSP1 compared to ECs from adjacent non-tumor livers. The reduced SMAD3 or TSP1 in ECs was associated with increased angiogenesis in HCC tissues. Collectively, this study identified that TGFβ1-TGFβR1-SMAD2/3-TSP1 signaling in ECs inhibits angiogenesis. This inhibition can be circumvented by a hypoxia-HIF1α-miR145 axis, elucidating a mechanism by which hypoxia promotes angiogenesis.

Importance: Vitiligo is a chronic skin disorder causing depigmentation. There is a lack of evidence-based medical evidence regarding ruxolitinib efficacy and safety for vitiligo., Objective: To assess the efficacy and safety of ruxolitinib cream in the treatment of vitiligo., Methods: The databases of PubMed, Embase, and Cochrane Library were searched. The literature screening was independently conducted by two reviewers., Data Extraction and Synthesis: For continuous variables, weighted mean difference (WMD) along with a 95% confidence interval (CI) was performed. For dichotomous outcomes, we calculated the odds ratios (ORs) or risk ratios (RRs), and their corresponding 95% CIs. The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE)., Main Outcomes and Measures: Symptoms, quality of life, and safety were evaluated using various measures, including the Facial Vitiligo Area Scoring Index (F-VASI), Total Vitiligo Area Scoring Index (T-VASI), Facial Body Surface Area (F-BAS), Total Body Surface Area (T-BAS) and Treatment-emergent Adverse Events (TEAEs)., Results: Three trials, involving a total of 830 participants from nine countries were included (female 388, 46.7%, male 442, 53.3%). The meta-analysis demonstrated a significant increase in the likelihood of participants achieving F-VASI75 (OR, 4.34 [95% CI 2.67-7.06]; high), F-VASI50 (OR 4.71 [95% CI 3.24-6.84]; high), T-VASI75 (OR 2.78 [95% CI 1.10-7.00]; moderate), and T-VASI50 (OR 4.47 [95% CI 2.52-7.92]; high) when compared ruxolitinib to vehicle. Ruxolitinib was associated with more lowered percentage change of F-VASI scores (MD - 32.79 [95% CI - 36.37 to - 29.21]; moderate), and T-VASI scores (MD - 20.22 [95% CI - 23.11 to - 17.33]; moderate) from baseline compared to vehicle. There may not be a significant difference in the occurrence of TEAEs between ruxolitinib and vehicle (RR 1.46 [95% CI 0.85-2.49]; high)., Conclusions: The findings suggest that ruxolitinib cream holds promise as a treatment option for vitiligo. Further long-term studies are needed to assess its sustained efficacy and safety profile., Systematic Review Registration: PROSPERO CRD42023431112., (© 2024. The Author(s).)

Aim: This paper aims to investigate the humanistic care ability among surgical nurses in China and identify its statistically significant influencing factors., Design: A cross-sectional, descriptive and correlational design was used., Methods: A total of 210 surgical nurses were recruited from a tertiary public hospital in Wuhu, Anhui Province. Four with incomplete responses were excluded, leaving 206 participants for data analysis. Variables were measured using the general questionnaire, caring ability inventory (CAI), and General Self-Efficacy Scale (GSES). Multivariate linear regression analyses were performed to identify the statistically significant influencing factors of participants' humanistic caring ability., Results: The overall average score of the CAI was 190.14 (SD = 19.24), and the average scores for the three dimensions of cognitive, courage, and patience were 70.46 (SD = 7.77), 62.12 (SD = 8.47) and 57.56 (SD = 6.02), respectively. The overall average score of the GSES was 26.05 (SD = 5.77). Professional attitude, perceived care from the department head nurse, perceived care from colleagues and self-efficacy were the statistically significant factors influencing the humanistic care ability of surgical nurses (R 2  = 0.45, adjusted R 2  = 0.44, F = 40.64, p < 0.001)., (© 2024 The Author(s).

Lung cancer is the leading cause of cancer deaths worldwide. Brain metastasis of lung cancer, which counts for nearly 50% of late-stage lung cancer patients, is a sign of a really poor prognosis. However, the presence of blood-brain barrier (BBB) and blood-brain tumor barrier (BBTB) limits the penetration of drugs from the blood into the brain and thus restricts their accumulation in brain tumors. Systematic delivery of drugs into brain and brain tumor lesion using BBB and BBTB penetrating vehicles represents a promising strategy to overcome the BBB and BBTB limitations. Hence, we validated one of our previously identified BBB/BBTB penetrating peptide and its drug conjugate form for the treatment of lung cancer brain metastasis. With in vitro experiment, we first validated that the receptor LRP1, which mediated the peptide penetration of the BBB, was expressed on lung cancer cells and thus can be targeted by the peptide to overcome BBTB. With this delivery peptide, we constructed peptide-paclitaxel conjugate (the PDC) and in vitro validation showed that the PDC can across the BBB and efficiently kill lung cancer cells. We therefore constructed mouse lung cancer brain metastasis xenograft. In vivo anti-tumor validations showed that the PDC efficiently inhibited the proliferation of the brain resident lung cancer cells and significantly expanded the survival of the mouse xenograft, with no visible damages to the organs. Overall, our study provided potential therapeutic drugs for the treatment of lung cancer brain metastasis that may be clinically effective in the near future., 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: We aimed to investigate the technical advantages and clinical outcomes of lateral unicompartmental knee arthroplasty (LUKA) through the medial parapatellar approach., Methods: From August 2022 to June 2024, 104 patients who underwent LUKA via the medial parapatellar approach were enrolled. The operation time, hospital stays, surgical complications and follow-up period were collected. Pre- and postoperative Range of movement (ROM), Oxford knee score (OKS) and Hospital for special surgery knee score (HSS) were recorded and further investigated by paired-samples t-test analysis., Results: Primary demographic data of the retrospective case series collected include gender (30 males and 74 females), age (63.1 ± 8.37 years, range 49-84 years), operation time (86 ± 17 min, range 52-135 min), hospital stays (4.0 ± 1.1 days, range 3-8 days) and follow-up period (9.9 ± 5.7 months, range 1-23 months). There was a significant improvement in ROM (P < 0.001), OKS (P < 0.001) and HSS (P < 0.001) compared to preoperative values. Patient satisfaction at 1-month postoperative follow-up was up to 95%. The incidence of deep venous thrombosis was 16.3%. There was no incidence of postoperative infection., Conclusion: The medial parapatellar approach is a understandable, easy to master and credible surgical approach for LUKA, showing a striking improvement in clinical outcomes without adverse events in the short-term follow-up., (© 2024.

Large-wound treatment often requires autologous skin grafting or skin flap transfer, causing iatrogenic secondary injuries. Thus, we have developed an automatic wound closure system that consists of a stretch module, microcontroller, and touch screen. Full-thickness wounds (8 × 14 cm) on Bama miniature pigs were manually closed by direct suture in control animals and with three different tension levels performed by the automatic device in the experimental animals. Wound-closure conditions, post-closure healing, and scars were evaluated. Post-operative microscopic changes in collagen fibers, local cell apoptosis, and changes in vascular density were compared between the two wound-closure techniques. In the control group and the first experimental group, which used a traction force of 15 N, primary wound closure could not be achieved. The other two experimental groups used a traction force of 30 N and 60 N and all wounds achieved primary closure. Collagen-fiber stretching was observed histologically in all groups and collagen-fiber breakdown occurred in some wounds when the traction force was 60 N. Scar hyperplasia was significantly reduced in the automatic wound closure system groups. The collagen content decreased, cell apoptosis increased, and vascular density decreased in local tissues in the early post-closure stage, but eventually recovered to normal-skin levels. In summary, we developed an automatic wound closure system that effectively and safely stretches dermal-collagen fibers under an appropriate traction force (30 N) and stretch wound-peripheral skin to cover the wound, achieve primary closure, and reduce scar hyperplasia., (© 2024.

Soy proteins are seen as a promising alternative food source for meat with environmentally friendly properties. The problem is that the functional properties of soy proteins do not meet the needs of the food industry, and some existing modification technologies have adverse effects. Recently, cavitation jet technology (CJT) has been studied because it generates high heat, high pressure, strong shear and strong shock waves. This review summarizes the history and mechanism of cavitation jets. The energy generated during the cavitation jet process can open molecular structures, and the shock waves and microjets generated can pulverize the materials by erosion. The impact of the CJT on the morphology, structure, and functionality of soy proteins is discussed. The impact of combining CJT with other techniques on the production of soy proteins was also reviewed. The modification of proteins using two or more methods with complementary strengths, avoiding the disadvantages of certain techniques, makes the modification of proteins more effective. One of the most prominent effects is the combined treatment of cavitation jets with physical techniques. Finally, the review provides a comprehensive analysis of the application of modified soy proteins in the food industry and highlights promising avenues for future research., 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.

This paper presents a reconfigurable near-sensor anomaly detection processor to real-time monitor the potential anomalous behaviors of amputees with limb prostheses. The processor is low-power, low-latency, and suitable for equipment on the prostheses and comprises a reconfigurable Variational Autoencoder (VAE), a scalable Self-Organizing Map (SOM) Array, and a window-size-adjustable Markov Chain, which can implement an integrated miniaturized anomaly detection system. With the reconfigurable VAE, the proposed processor can support up to 64 sensor sampling channels programmable by global configuration, which can meet the anomaly detection requirements in different scenarios. A scalable SOM array allows for the selection of different sizes based on the complexity of the data. Unlike traditional time accumulation-based anomaly detection methods, the Markov Chain is utilized to detect time-series-based anomalous data. The processor is designed and fabricated in a UMC 40-nm LP technology with a core area of 1.49 mm 2 and a power consumption of 1.81 mW. It achieves real-time detection performance with 0.933 average F1 Score for the FSP dataset within 24.22 μs, and 0.956 average F1 Score for the SFDLA-12 dataset within 30.48 μs. The energy dissipation of detection for each input feature is 43.84 nJ with the FSP dataset, and 55.17 nJ with the SFDLA-12 dataset. Compared with ARM Cortex-M4 and ARM Cortex-M33 microcontrollers, the processor achieves energy and area efficiency improvements ranging from 257 ×, 193 × and 11 ×, 8 ×, respectively.

Zinc finger protein 180 (ZNF180) is a multifunctional protein that interacts with nucleic acids and regulates various cellular processes; however, the function of ZNF180 in colorectal cancer (CRC) remains unclear. The present study investigated the role and function of ZNF180 in CRC, and aimed to reveal the underlying molecular mechanism. The results revealed that ZNF180 was downregulated in CRC tissues and was associated with a good prognosis in patients with CRC. Additionally, the expression of ZNF180 was downregulated by methylation in CRC. In vivo and in vitro experiments revealed that ZNF180 overexpression was functionally associated with the inhibition of cell proliferation and the induction of apoptosis. Mechanistically, chromatin immunoprecipitation‑PCR and luciferase assays demonstrated that ZNF180 markedly regulated the transcriptional activity of methyltransferase 14, N6‑adenosine‑methyltransferase non‑catalytic subunit (METTL14) by directly binding to and activating its promoter region. Simultaneous overexpression of ZNF180 and knockdown of METTL14 indicated that the reduction of METTL14 could suppress the effects of ZNF180 on the induction of apoptosis. Clinically, the present study observed a significant positive correlation between ZNF180 and METTL14 expression levels, and low expression of ZNF180 and METTL14 predicted a poor prognosis in CRC. Overall, these findings revealed a novel mechanism by which the ZNF180/METTL14 axis may modulate apoptosis and cell proliferation in CRC. This evidence suggests that this axis may serve as a prognostic biomarker and therapeutic target in patients with CRC.

Photo-responsive adsorption has emerged as a vibrant area because it provides a promising route to reduce the energy consumption of the traditional adsorption separation. However, the current methodology to fabricate photo-responsive sorbents is still subject to the photo-deforming molecular units. In this study, a new initiative of photo-dissociated electron-hole pairs is proposed to generate amazing adsorption activity, and prove its feasibility. Employing CuPP [PP = 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin] framework nanosheets compounded with graphene, binary film (BF) sorbents are successfully fabricated. The paradigmatic BF nanostructure brings about efficiently photo-excited electron-hole pairs with durable enough lifetime to meet the needs of microscopic adsorption equilibrium, which ultimately alters the electron density distribution of adsorption surface, and thus markedly modulates the adsorption activity. Therefore, an amazing photo-enhanced adsorption capability for the index gas CO can be gotten. Once exposed to the visible-light at 420 nm, the CO adsorption capacity (0 °C, 1 bar) is risen from 0.23 mmol g -1 in the darkness to 1.66 mmol g -1 , changed by + 622%. This is essentially different from majority of current photo-responsive sorbents based on photo-deforming molecular units, of which adsorption capability is only decreased with photo-induction, and the maximum rate of change reported is just -54%., (© 2024 Wiley‐VCH GmbH.)

The agricultural pest Drosophila suzukii exhibits a strong preference for feeding on fresh fruits, demonstrating high adaptability to sugary environments. Meanwhile, high sugar levels stimulate insulin secretion, thereby regulating the steady state of sugar metabolism. Understanding the mechanisms related to sugar metabolism in D. suzukii is crucial due to its adaptation to these specific environmental conditions. The insulin signaling pathway is an evolutionarily conserved phosphorylation cascade with significant roles in development and metabolism. We observed that the activation of the insulin signaling pathway inhibited FoxO activity and downregulated the expression of Pepck , thereby activating glycolysis and reducing glucose levels. By contrast, inhibiting insulin signaling increased the FoxO activity and upregulated the expression of Pepck , which activated gluconeogenesis and led to increased glucose levels. Our findings demonstrated the crucial role of the insulin signaling pathway in mediating glucose metabolism through the FoxO-Pepck axis, which supports the ecological adaptation of D. suzukii to high-sugar niches, thereby providing insights into its metabolic control and suggesting potential strategies for pest management. Elucidating these molecular processes is important for understanding metabolic regulation and ecological specialization in D. suzukii .

Iliac vein compression syndrome (IVCS) is a clinical condition defined as obstruction of the iliac vein caused by chronic compression imposed by various causes. Currently, the clinical role of computed tomography venography (CTV) in the diagnosis of IVCS is unclear. Accurately diagnosing IVCS using CTV may enhance the understanding of the pathological anatomy of iliac veins, which may lead to better treatment outcomes, especially for recalcitrant venous leg ulcers (VLU). We aimed to investigate diagnostic criteria, contributing clinical factors, and stenting for IVCS with VLU in this study. CTV, digital subtraction angiography (DSV), and Doppler ultrasound (DUS) data were obtained from the medical and imaging records of 62 patients. Additionally, contributing factors and stenting for IVCS were analysed. Patients (100%) had clinical, aetiological, anatomic, or pathological C6 disease. CTV reduced the procedure time and contrast medium dose and provided more information than DSV. Risk factors for IVCS with VLU included female sex (P = 0.036) and advanced age (P = 0.014). The rate of ulcer healing was lower in the IVCS group without stent implantation (P = 0.020). Significant improvements were noted in venous clinical severity scores (P < 0.001) and chronic venous insufficiency questionnaire-20 scores (P < 0.001) after stenting for IVCS with C6 ulcers. CTV provides a more accurate diagnosis than DUS and DSV and allows detection of possible causes of IVCS. Female sex and advanced age were potential contributing factors for IVCS. Satisfactory outcomes were observed with stenting in the treatment of IVCS with C6 ulcers., (© 2024. The Author(s).)

Purpose: In children, obstructive sleep apnea (OSA) is associated with growth hormone level abnormalities and chronic systemic inflammation. This study was performed to investigate the relationship of the degree of OSA with insulin-like growth factor 1 (IGF-1) and inflammatory cytokines in pediatric OSA and the inter-relationship between inflammatory cytokines and growth hormones. Methods: Children with OSA and controls without OSA participated in the study. Information included polysomnography followed by measurement of IGF-1 and inflammatory marker levels. In total, 226 patients aged 2 to 12 years were divided into 4 groups: non-OSA, n = 57 (25.2%); mild OSA, n = 116 (51.3%); moderate OSA, n = 23 (10.2%); and severe OSA, n = 30 (13.3%). Results: Body height was not significantly different among the 4 groups. However, the minimum oxygen saturation and IGF-1 significantly differed among the different OSA groups ( P = .0001 and P = .036, respectively). IGF-1 was significantly higher in the non-OSA group ( P < .05) and mild OSA group ( P < .01) than in the severe OSA group. As the severity of OSA increased, the interleukin-5 level significantly increased, which caused a difference between mild OSA and moderate OSA ( P < .05) and between mild OSA and severe OSA ( P < .001). In the univariate quantile regression analysis of IGF-1, there was a negative relationship between IGF-1 and IL-5 ( P < .001). IGF-1 was positively correlated with age, height, and minimum oxygen saturation. Furthermore, there was a negative correlation between the IGF-1 level and the severity of OSA. Quantile regression analysis on the multivariable analysis of the IGF-1 association showed that height, sex, and severity of OSA played important roles in affecting IGF-1 levels. Conclusion: High IL-5 levels may lead to the low secretion of growth hormone level (IGF-1) in children, thus affecting growth and development., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Generalized anxiety disorder (GAD) is a relatively common mental disorder. Recently, inflammation, an important factor for the development of depression, has attracted increasing attention. Several studies have shown that inflammatory cytokines can affect the pathophysiological processes of several nervous system diseases. We hypothesized that there is a correlation between the levels of lipopolysaccharide (LPS)-stimulated inflammatory cytokines and the clinical symptoms of GAD., Aim: To investigate the predictive effect of LPS-stimulated inflammatory cytokines on symptoms of GAD., Methods: This was a cross-sectional study in which 89 patients with GAD diagnosed at The First Hospital of Hebei Medical University from January 2022 to December 2022 and 70 individuals without anxiety and depression (controls) during the same period were included. Fasting venous blood was collected from all the subjects in heparin tubes, and another 3 ml of blood was supplemented with LPS (10 ng/ml). The plasma levels of 12 cytokines [Interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-17A, IL-12p70, and IFN-α] were detected., Results: Post-LPS stimulation, the levels of IL-1β, IL-6, IL-8, IL-10, and TNF-α in both the control and GAD groups were significantly elevated above those in the nonstimulated groups, with IL-6 and IL-8 showing marked increases. Increases in IL-8 and TNF-α were statistically significant in the GAD group ( P < 0.05). IL-1β, IL-6, IL-8, IL-10, and TNF-α were found to be significantly correlated with Hamilton Anxiety Rating Scale (HAMA) scores ( P < 0.05). A negative correlation was observed between IL-10 levels and HAMA scores. Further analysis revealed that TNF-α was associated with mental anxiety, whereas IL-1β, IL-8, and IL-10 were associated with physical anxiety symptoms, with IL-10 showing a negative correlation with physical anxiety. IL-6 was associated with both mental and physical aspects of anxiety., Conclusion: The physical symptoms of GAD are related to inflammatory factors. IL-1β, IL-8, IL-10, and TNF-a can be used as predictors of physical or mental anxiety in patients with GAD., Competing Interests: Conflict-of-interest statement: The authors declared that they have no conflicts of interest regarding this work., (©The Author(s) 2024.

Serine protease 50 (PRSS50/TSP50) is highly expressed in spermatocytes. Our study investigated its role in testicular development and spermatogenesis. Initially, PRSS50 knockdown was observed to impair DNA synthesis in spermatocytes. To further explore this, we generated PRSS50 knockout ( Prss50 -/- ) mice ( Mus musculus ), which exhibited abnormal spermatid nuclear compression and reduced male fertility. Furthermore, dysplastic seminiferous tubules and decreased sex hormones were observed in 4-week-old Prss50 -/- mice, accompanied by meiotic progression defects and increased apoptosis of spermatogenic cells. Mechanistic analysis indicated that PRSS50 deletion resulted in increased phosphorylation of extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) and elevated levels of MAP kinase phosphatase 3 (MKP3), a specific ERK antagonist, potentially accounting for testicular dysplasia in adolescent Prss50 -/- mice. Taken together, these findings suggest that PRSS50 plays an important role in testicular development and spermatogenesis, with the MKP3/ERK signaling pathway playing a significant role in this process.

The residue of mulch film is a crucial source of microplastics (MPs) in agricultural fields. The effects of mulch film-derived MPs on the environmental behavior of pesticides in agriculture remain unclear. In the present study, the effects of MPs of different sizes (5 mm, 1 mm, 30 µm, and 0.3 µm) at environmentally relevant concentrations on pesticide transport were evaluated, and the mechanism was explored with respect to adsorption and pore structure using fluorescence visualization, the extended Derjaguin-Landau-Verwey-Overbeek model, and microcomputed tomography. MPs were found to be retained in the soil due to size limitation, pore capture, and surface adhesion. The presence of mm-sized MPs (5 and 1 mm) at a concentration of 0.25 % inhibited the leaching behavior of atrazine, metolachlor, and tebuconazole. MPs did not significantly alter the pesticide adsorption ability of the soil. The reduced leaching originated from the impact of MPs on soil pore structure. Specifically, the porosity increased by 16.2-25.0 %, and the connectivity decreased by 34.5 %. These results demonstrate that mm-sized MPs inhibit pesticide leaching by obstructing the pores and altering the transport pathways, thereby potentially elevating environmental risks, particularly to the soil ecosystem., 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.

Famoxadone is a chiral fungicide frequently found in the environment and agricultural products. However, the health risks of famoxadone enantiomers are not well understood. This study investigated the stereoselective cytotoxicity and metabolic behavior of famoxadone enantiomers in mammals. Results showed that R-famoxadone was 1.5 times more toxic to HepG2 cells than S-famoxadone. R-famoxadone induced more pronounced ferroptosis compared to S-famoxadone. It caused greater upregulation of genes related to iron transport and lipid peroxidation, and greater downregulation of genes related to peroxide clearance. Furthermore, R-famoxadone induced more severe lipid peroxidation and reactive oxygen species (ROS) accumulation through ACSL4 activation and GPX4 inhibition. Additionally, the bioavailability of R-famoxadone in mice was six times higher than that of S-famoxadone. Liver microsome assays, cytochrome P450 (CYP450) inhibition assays, human recombinant CYP450 assays, and molecular docking suggested that the lower binding affinities of CYP2C8, CYP2C19, and CYP2E1 for R-famoxadone caused its preferential accumulation. Overall, R-famoxadone poses a higher risk than S-famoxadone due to its greater cytotoxicity and persistence. This study provides the first evidence of ferroptosis-induced stereoselective toxicity, offering insights for the comprehensive health risk assessment of chiral famoxadone and valuable references for the application of high-efficiency, low-risk pesticide enantiomers., 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.

The structural, photophysical, and photochemical properties of Ln(depma)(hmpa) 2 (NO 3 ) 3 (Ln = La, Ce, Nd, Sm, Eu, Tb, Ho, Er, and Yb) complexes 1-Ln were investigated with a multidisciplinary approach involving synthesis, photocycloaddition-based crystal engineering, spectroscopic analytical techniques and quantum chemical ab initio calculations. Depending on the Ln 3+ ion the isostructural 1-Ln complexes exhibit quite different behavior upon excitation at 350-400 nm. Some 1-Ln complexes (Ln = La, Ce, Sm, Tb, Yb) emit a broad and strong band near 533 nm arising from paired anthracene moieties, whereas others (Ln = Nd, Eu, Ho, Er) do not. 1-Eu is not emissive at all, whereas 1-Nd , 1-Ho , and 1-Er exhibit a Ln 3+ based luminescence. Upon irradiation with 365 nm ultraviolet (UV) light 1-Ln (Ln = La, Ce, Sm, Tb, Yb) dimerize by means of a photochemically induced [4 + 4] cycloaddition of the anthracene moieties, whereas 1-Ln (Ln = Nd, Eu, Ho, Er) remain monomers. We propose three models, based on the matching of the energy levels between the Ln 3+ ion and the paired or dimerized anthracene units in the energy-resonance crossing region, as well as on internal conversion-driven and intersystem crossing-driven energy transfer, which explain the Ln 3+ ion regulated photophysics and photochemistry of the 1-Ln complexes., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

Hypertrophic scar development is a complication associated with wound healing, impacting local appearance and function. The type I/III collagen ratio affects the extent of hypertrophic scarring; a reduced ratio can ameliorate this. In this study, recombinant human collagen type III was developed. Liquid chromatography-tandem mass spectrometry was used to determine its amino acid sequence and confirm its high level of homology with natural human type III collagen. Recombinant human collagen type III displayed no cytotoxicity and did not confer skin irritation and sensitization. Immunofluorescence and western blot analyses of histidine following incubation with fibroblasts suggested cell entry of recombinant human collagen type III. Furthermore, recombinant human collagen type III promoted the synthesis of the natural type III collagen in fibroblasts, resulting in a more obvious increase of type III collagen content in fibroblasts than that of type I collagen, and then decreased the ratio of type I/III collagen. The results of 5-ethynyl-2'-deoxyuridine staining assay suggested enhanced fibroblast proliferation. Following local injection of recombinant human collagen type III, rabbit ear scarring was significantly reduced after 60 days. Vancouver Scar Scale evaluation showed that all index scores were significantly reduced. Western blotting and Picro-Sirius red staining showed that the natural type III collagen increase in scar tissue was greater than that of type I collagen, decreasing the type I/III ratio. In summary, recombinant human collagen type III can be taken up by fibroblasts and promote natural collagen synthesis-especially that of type III-thereby reducing the type I/III ratio and improving hypertrophic scarring., (© The Author(s) 2024.

Introduction: Sleep deprivation(SD) has numerous negative effects on mental health. A growing body of research has confirmed the implication of gut microbiota in mental disorders. However, the specific modifications in mammalian gut microbiota following SD exhibit variations across different studies., Methods: Male specific-pathogen-free Wistar rats were given a modified multiple-platform exposure for 7 days of SD. Fecal samples were obtained from the control and SD groups both at baseline and after 7 days of SD. We utilized 16S rDNA gene sequencing to investigate the gut microbial composition and functional pathways in rats., Results: Analysis of the microbiota composition revealed a significant change in gut microbial composition after chronic SD, especially at the phylum level. The relative abundances of p&#95;Firmicutes, g&#95;Romboutsia , and g&#95;Enterococcus increased, whereas those of p&#95;Bacteroidetes, p&#95;Verrucomicrobia, p&#95;Fusobacteria, g&#95;Akkermansia , and g&#95;Cetobacterium decreased in animals after chronic SD compared with controls or animals before SD. The ratio of Firmicutes to Bacteroidetes exhibited an increase following SD. The relative abundance of gut microbiota related to the functional pathways of GABAergic and glutamatergic synapses was observed to be diminished in rats following SD compared to pre-SD., Conclusion: Collectively, these findings suggest that chronic SD causes significant alterations in both the structural composition and functional pathways of the gut microbiome. Further researches are necessary to investigate the chronological and causal connections among SD, the gut microbiota and mental disorders., Competing Interests: The authors declare no conflicts of interest in this work., (© 2024 Zheng and Li.)
