Application of Traditional Chinese Culture in Cross-Cultural English Education:A Case Study of the Maritime Silk Road in Guangdong Province

The phenomenon of aphasia in Chinese culture is serious.The existing English teaching materials emphasize too much Western culture education and lack traditional Chinese cultural elements.Therefore,this paper takes the Guangdong Maritime Silk Road as an example to study the specific application of traditional Chinese culture in cross-cultural English education.This paper first summarizes the significance of cross-cultural integration into college English education and then points out the serious phenomenon of Chinese cultural aphasia.Next,the paper focuses on English education,using English textbooks as a starting point to explore and integrate strategies related to excellent traditional Chinese culture from the Guangdong Maritime Silk Road.By integrating traditional Chinese culture into business English classes(with the Guangdong Maritime Silk Road as an example),the study explores the influence of such cultural integration on students’cross-cultural communication skills,cultural identity,and learning effects.The results showed that the P value of the experimental group and the control group was<0.05,that is,cultural integration had a positive effect on improving the effect of cross-cultural English education.The overall scores and cultural confidence of the experimental group are higher than those of the control group,which proves that cross-cultural teaching has a positive effect on the improvement of students’scores.

High-definition transcranial direct current stimulation over the right dorsolateral prefrontal cortex reduces risk-taking

Taking risks is essential for daily life,1 as it reflects an individual’s inclination towards activities that may have positive outcomes despite the possibility of negative results,such as losses or harm.2 Insufficiency in risk-taking can lead to addictive behaviours and other mental health issues.2 The Balloon Analogue Risk Task(BART)3 is a commonly used method to assess risk-taking behaviour.4 Previous research had suggested that risk-taking behaviour was linked to the activity of the right dorsolateral prefrontal cortex(DLPFC).

Paleoproterozoic volcanic rocks in the southern margin of the North China Craton, central China:Implications for the Columbia supercontinent

The volcanic rocks of the Xiong’er Group are situated in the southern margin of the North China Craton(NCC).Research on the Xiong er Group is important to understand the tectonic evolution of the NCC and the Columbia supercontinent during the Paleoproterozoic.In this study,to constrain the age of the Xiong’er volcanic rocks and identify its tectonic environment,we report zircon LA-ICP-MS data with Hf isotope,whole-rock major and trace element compositions and Sr-Nd-Pb-Hf isotopes of the volcanic rocks of the Xiong’er Group.The Xiong’er volcanic rocks mainly consist of basaltic andesite,andesite.dacite and rhyolite,with minor basalt.Our new sets of data combined with those from previous studies indicate that Xiong’er volcanism should have lasted from 1827 Ma to 1746 Ma as the major phase of the volcanism.These volcanics have extremely low MgO.Cr and Ni contents,are enriched in LREEs and LILEs but depleted in HFSEs(Nb,Ta,and Ti),similar to arc-related volcanic rocks.They are characterized by negative zirconεHft values of-17.4 to 8.8,whole-rock initial 87Sr/86Sr values of 0.7023 to 0.7177 andεNd(t)values of-10.9 to 6.4.and Pb isotopes(206Pb/204Pb=14.366-16.431,207Pb/204Pb=15.106-15.371,208Pb/204Pb=32.455-37.422).The available elemental and Sr-Nd-Pb-Hf isotope data suggest that the Xiong’er volcanic rocks were sourced from a mantle contaminated by continental crust.The volcanic rocks of the Xiong’er Group might have been generated by high-degree partial melting of a lithospheric mantle that was originally modified by oceanic subduction in the Archean.Thus,we suggest that the subduction-modified lithospheric mantle occurred in an extensional setting during the breakup of the Columbia supercontinent in the Late Paleoproterozoic,rather than in an arc setting.

Identification and functional characterization of female antennae-biased odorant receptor 23 involved in acetophenone detection of the Indian meal moth Plodia interpunctella

The Indian meal moth,Plodia interpunctella(Lepidoptera:Pyralidae),a globally distributed storage pest,relies on odors that are emitted from stored foods to select a suitable substrate for oviposition.However,the molecular mechanism underlying the chemical communication between P.interpunctella and its host remains elusive.In this study,130 chemosensory genes were identified from the transcriptomes of 7 P.interpunctella tissues,and the quantitative expression levels of all 56 P.interpunctella odorant receptor genes(PintORs)were validated using real-time quantitative polymerase chain reaction.The functional characteristics of 5 PintORs with female antennae-biased expression were investigated using 2-electrode voltage clamp recordings in Xenopus laevis oocytes.PintOR23 was found to be specifically tuned to acetophenone.Acetophenone could elicit a significant electrophysiological response and only attracted mated females when compared with males and virgin females.In addition,molecular docking predicted that the hydrogen bonding sites,TRP-335 and ALA-167,might play key roles in the binding of PintOR23 to acetophenone.Our study provides valuable insights into the olfactory mechanism of oviposition substrate detection and localization in P.interpunctella and points toward the possibility of developing eco-friendly odorant agents to control pests of stored products.

Emerging role of lncRNAs as mechanical signaling molecules in mechanotransduction and their association with Hippo-YAP signaling:a review

Cells within tissues are subject to various mechanical forces,including hydrostatic pressure,shear stress,compression,and tension.These mechanical stimuli can be converted into biochemical signals through mechanoreceptors or cytoskeleton-dependent response processes,shaping the microenvironment and maintaining cellular physiological balance.Several studies have demonstrated the roles of Yes-associated protein(YAP)and its homolog transcriptional coactivator with PDZ-binding motif(TAZ)as mechanotransducers,exerting dynamic influence on cellular phenotypes including differentiation and disease pathogenesis.This regulatory function entails the involvement of the cytoskeleton,nucleoskeleton,integrin,focal adhesions(FAs),and the integration of multiple signaling pathways,including extracellular signal-regulated kinase(ERK),wingless/integrated(WNT),and Hippo signaling.Furthermore,emerging evidence substantiates the implication of long non-coding RNAs(lncRNAs)as mechanosensitive molecules in cellular mechanotransduction.In this review,we discuss the mechanisms through which YAP/TAZ and lncRNAs serve as effectors in responding to mechanical stimuli.Additionally,we summarize and elaborate on the crucial signal molecules involved in mechanotransduction.

Protein translation:biological processes and therapeutic strategies for human diseases

Protein translation is a tightly regulated cellular process that is essential for gene expression and protein synthesis.The deregulation of this process is increasingly recognized as a critical factor in the pathogenesis of various human diseases.In this review,we discuss how deregulated translation can lead to aberrant protein synthesis,altered cellular functions,and disease progression.We explore the key mechanisms contributing to the deregulation of protein translation,including functional alterations in translation factors,tRNA,mRNA,and ribosome function.Deregulated translation leads to abnormal protein expression,disrupted cellular signaling,and perturbed cellular functions-all of which contribute to disease pathogenesis.The development of ribosome profiling techniques along with mass spectrometry-based proteomics,mRNA sequencing and single-cell approaches have opened new avenues for detecting diseases related to translation errors.Importantly,we highlight recent advances in therapies targeting translation-related disorders and their potential applications in neurodegenerative diseases,cancer,infectious diseases,and cardiovascular diseases.Moreover,the growing interest lies in targeted therapies aimed at restoring precise control over translation in diseased cells is discussed.In conclusion,this comprehensive review underscores the critical role of protein translation in disease and its potential as a therapeutic target.Advancements in understanding the molecular mechanisms of protein translation deregulation,coupled with the development of targeted therapies,offer promising avenues for improving disease outcomes in various human diseases.Additionally,it will unlock doors to the possibility of precision medicine by offering personalized therapies and a deeper understanding of the molecular underpinnings of diseases in the future.

Preparation and Characterization of Waterborne Polyurethane/Cellulose Nanocrystal Composite Membrane from Recycling Waste Paper

Cellulose plays a key role in abundant organic natural materials meeting the increasing demand for green and biocompatible products.The highly crystalline nanoscale component of cellulose nanocrystals has recently attracted great attention due to the versatile performance as filler or matrix in producing functional materials.In this work,we prepared the waterborne polyurethane via a prepolymer process,and obtained cellulose and cellulose nanocrystals from waste paper via a facile acid hydrolysis process.After that,the cellulose nanocrystals were assembled into film and mixed with polyurethane to prepare flexible polyurethane/cellulose nanocrystals composite membrane with different soaking time.The correlation between the bulk structure and applied properties including thermal resistance and mechanical property was investigated by using Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(SEM),thermogravimetric analysis(TGA),differential scanning calorimetry(DSC)and folding test.The structure analysis indicates that cellulose nanocrystals prepared from used paper have a quality similar to that of commercial cellulose.Meanwhile,the cellulose nanocrystals have been mixed with polyurethane uniformly.Polyurethane can significantly benefit to the thermal resistance and mechanical property of the cellulose nanocrystals film.The polyurethane/cellulose nanocrystals composite membrane present good flexibility and may hold a significantly potential application as visual and flexible material.

Molecular genetic analysis of phosphomannomutase genes in Triticum monococcum

In higher plants, phosphomannomutase(PMM) is essential for synthesizing the antioxidant ascorbic acid through the Smirnoff–Wheeler pathway. Previously, we characterized six PMM genes(Ta PMM-A1, A2, B1, B2, D1 and D2) in common wheat(Triticum aestivum, AABBDD).Here, we report a molecular genetic analysis of PMM genes in Triticum monococcum(AmAm), a diploid wheat species whose Amgenome is closely related to the A genome of common wheat. Two distinct PMM genes, Tm PMM-1 and Tm PMM-2, were found in T. monococcum. The coding region of Tm PMM-1 was intact and highly conserved. In contrast, two main Tm PMM-2 alleles were identified, with Tm PMM-2a possessing an intact coding sequence and Tm PMM-2b being a pseudogene. The transcript level of Tm PMM-2a was much higher than that of Tm PMM-2b, and a bacterially expressed Tm PMM-2a recombinant protein displayed relatively high PMM activity. In general, the total transcript level of PMM was substantially higher in accessions carrying Tm PMM-1 and Tm PMM-2a than those harboring Tm PMM-1 and Tm PMM-2b. However, total PMM protein and activity levels did not differ drastically between the two genotypes. This work provides new information on PMM genes in T. monococcum and expands our understanding on Triticeae PMM genes, which may aid further functional and applied studies of PMM in crop plants.

Repurposed benzydamine targeting CDK2 suppresses the growth of esophageal squamous cell carcinoma

Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway.

Cysteine mutations impair the structural stability of phosphomannomutase 2(PMM2)in glycosylation-associated metabolic disorders

Glycosylation is a ubiquitous molecular modification in the process of cellular metabolism regulation,which plays a vital role in maintaining and regulating cellular functions.Deficiency in glycosylation enzymes may jeopardize the glycosylation process and eventually lead to the metabolic disease,manifesting with either a neurologic or multisystem phenotype,which is also known as congenital disorder of glycosylation(CDG).1 It could be classified into type I CDG and type II CDG,and the latter was referred to as the abnormal formation of nascent glycoprotein.Phosphomannomutase 2 CDG(PMM2-CDG),the most prevalent CDG with an incidence rate of 1 in 20,000 individuals,is mainly due to the metabolic disorder of phosphomannomutase 2(PMM2).2 PMM2 participates in the conversion of mannose-6-phosphate to mannose-1-phosphate.The cysteine residues,as one of the least abundant amino acids,have unique attributes to maintain the stability of protein structure,especially for catalytic activity and protein folding.3 Therefore,cysteine mutations have been identified in various diseases including PMM2-CDG.Suggested by the crystal structure of PMM2(PDB ID:7O5Z),4 four cysteine mutations in the hPMM2,C9Y,C103F,C192G,and C241S,have been found in PMM2-CDG.After bioinformatic analysis by PROVEAN,the four cysteine mutations were predicted with“Deleterious”,ranking with the best two were C103F and C192G(C9Y:−5.493,C103F:−6.339,C192G:−11.176,C241S:−2.986).However,the underlying pathological mechanism is still unclear.Among them,C103F and C192G have only been reported in clinical study without a detailed explanation,so they were selected for our research.Two mutants were located near the linker region 1 and 2;C103F was located on the No.4αhelix and C192G was located on the No.7αhelix(Fig.S1A).The purpose of this study was to explore the structure and function roles of PMM2 clinical mutation and investigate the role of cysteine in PMM2 which might provide new insights into preventive and therapeutic strategies for PMM2-CDG.

Intense Intramolecular Charge Transfer Endows Cyanated Polymer with Broad Absorption,Intensified Light-Harvesting,Long-Lived Exciton,and Superior Photovoltaic Property

The donor–acceptor(D–A)copolymers,which exhibit wide broad absorption and intensified light-harvesting,are highly captivating for applications in solar conversion and optoelectronics.However,designing a polymer structure that can achieve these photophysical properties simultaneously remains a challenge.Herein,we report two novel cyanated units 4-cyanobenzo[1,2-b:6,5-b′:3,4-c″]trithiophene(CBT)and 4,6-dicyanobenzo[1,2-b:6,5-b′:3,4-c″]trithiophene(C2BT)and their corresponding polymers,PCBT and PC2BT.Very interestingly,the PC2BT exhibited a broad absorption band with full width at half maxima(FWHM)of its absorption spectra,almost twice wider than PCBT and benchmark polymers PM6 and D18.Moreover,the PC2BT demonstrated intensified light-harvesting and long-lived exciton.Our in-depth investigation unveiled that the presence of dicyano substitutions induced a strong intramolecular charge transfer(ICT),which,in turn,resulted in the formation of favorable photophysical properties.Therefore,PC2BT-based polymer solar cells(PSCs)exhibited an efficiency of 18.06%,which was a record-setting efficiency for cyanated polymers.This study suggests an efficient strategy for enhancing ICT to design polymers toward favorable photophysical properties and excellent photovoltaic performance.

Near-infrared non-fused electron acceptors for efficient organic photovoltaics

Developing narrow-bandgap organic semiconductors is important to facilitate the advancement of organic photovoltaics(OPVs). Herein, two near-infrared non-fused ring acceptors(NIR NFRAs), PTBFTT-F and PTBFTT-Cl have been developed with A-π_A-π_D-D-π_D-π_A-A non-fused structures. It is revealed that the introduction of electron deficient π-bridge(π_A) and multiple intramolecular noncovalent interactions effectively retained the structural planarity and intramolecular charge transfer of NFRAs, extending strong NIR photon absorption up to 950 nm. Further, the chlorinated acceptor, with the enlarged π-surface compared to the fluorinated counterpart, promoted not only molecular stacking in solid, but also the desirable photochemical stability in ambient, which are helpful to thereby improve the exciton and charge dynamics for the corresponding OPVs. Overall, this work provides valuable insights into the design of NIR organic semiconductors.

P2P Energy Trading Considering Prosumer Preference and System Risk

As an important means of mobilizing demand-side resources,peer-to-peer(P2P)energy trading has drawn more and more attention from scholars.This paper constructs a P2P energy trading framework considering prosumers’trading partner preferences(TPPs)and system risk.At first,we build the P2P trading models of prosumers equipped with different distributed energy resources(DERs),and TPP models.Secondly,to solve the established energy trading problem,a fully distributed double-consensus alternating direction method of multipliers(DC-ADMM)is proposed,which can achieve transaction consensus when considering market players’TPPs.Then,a risk-based security constrained economic dispatch(RBSCED)model based on AC power flow is established for the first time,by which a distribution system operator(DSO)checks system security and obtains risk-based locational marginal prices(RLMPs).Moreover,double-regulated price signals related to RLMPs which contain grid utilization prices(GUPs)and DSO’s retail prices realize management of players’transactions.In the end,the proposed method is applied to an IEEE33 bus distribution system.Results show the proposed method effectively reduces system risk and ensures secure operation of system without direct management.

Mitochondrial GRIM19 Loss Induces Liver Fibrosis through NLRP3/IL33 Activation via Reactive Oxygen Species/NF-κB Signaling

Background and Aims:Hepatic fibrosis(HF)is a critical step in the progression of hepatocellular carcinoma(HCC).Gene associated with retinoid-IFN-induced mortality 19(GRIM19),an essential component of mitochondrial respiratory chain complex I,is frequently attenuated in various human cancers,including HCC.Here,we aimed to investigate the potential relationship and underlying mechanism between GRIM19 loss and HF pathogenesis.Methods:GRIM19 expression was evaluated in normal liver tissues,hepatitis,hepatic cirrhosis,and HCC using human liver disease spectrum tissue microarrays.We studied hepatocyte-specific GRIM19 knockout mice and clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein-9(Cas9)lentivirus-mediated GRIM19 gene-editing in murine hepatocyte AML12 cells in vitro and in vivo.We performed flow cytometry,immunofluorescence,immunohistochemistry,western blotting,and pharmacological intervention to uncover the potential mechanisms underlying GRIM19 loss-induced HF.Results:Mitochondrial GRIM19 was progressively downregulated in chronic liver disease tissues,including hepatitis,cirrhosis,and HCC tissues.Hepatocyte-specific GRIM19 heterozygous deletion induced spontaneous hepatitis and subsequent liver fibrogenesis in mice.In addition,GRIM19 loss caused chronic liver injury through reactive oxygen species(ROS)-mediated oxidative stress,resulting in aberrant NF-κB activation via an IKK/IKB partner in hepatocytes.Further-more,GRIM19 loss activated NLRP3-mediated IL33 signaling administration of the NLRP3 inhibitor MCC950 dramatically via the ROS/NF-κB pathway in hepatocytes.Intraperitoneal alleviated GRIM19 loss-driven HF in vivo.Conclusions:The mitochondrial GRIM19 loss facilitates liver fibrosis through NLRP3/IL33 activation via ROS/NF-κB signaling,providing potential therapeutic approaches for earlier HF prevention.

Establishment and Application of a Radiation Dose Rate Model for Nuclear Medicine Examinees

Introduction:Traditional methods for determining radiation dose in nuclear medicine include the Monte Carlo method,the discrete ordinate method,and the point kernel integration method.This study presents a new mathematical model for predicting the radiation dose rate in the vicinity of nuclear medicine patients.Methods:A new algorithm was created by combining the physical model of“cylinder superposition”of the human body with integral analysis to assess the radiation dose rate in the vicinity of nuclear medicine patients.Results:The model accurately predicted radiation dose rates within distances of 0.1–3.0 m,with a deviation of less than 11%compared to observed rates.The model demonstrated greater accuracy at shorter distances from the radiation source,with a deviation of only 1.55%from observed values at 0.1 m.Discussion:The model proposed in this study effectively represents the spatial and temporal distribution of the radiation field around nuclear medicine patients and demonstrates good agreement with actual measurements.This model has the potential to serve as a radiation dose rate alert system in hospital environments.

Tea stain-inspired solar energy harvesting polyphenolic nanocoatings with tunable absorption spectra

Discovery and development of new sustainable photothermal materials with tunable light absorption spectra play a key role in solar energy harvesting and conversion.One possible solution to this quest is to check nature as a source of matters or inspiration.Inspired by the formation of tea stains,a unique class of dark stain materials generated by the interfacial reaction between tea polyphenols and metal substance,we reported the facile preparation and screening of a series of photothermal nanocoating layers via the metal ion(i.e.C u(ll)>Fe(lll),Ni(ll),Zn(ll))promoted in situ polymerization of typical phenolic moieties of tea polyphenols(i.e.,catechol and pyrogallol).It was found that those resulting metal-polyphenolic nanocoatings showed various promising features,such as high blackness and strong adhesion,excellent and tunable light absorption properties,good hydrophilicity and long-term stability.We further fabricated the photothermal composite devices by/n s/'fty formation of meta卜polyphenolic nanocoatings on pristine silks for solar desalination,which demonstrated promising durable evaporation behaviors with excellent evaporation rates and steam generation efficiencies.We believe that this work could provide more opportunities towards new types of bio-inspired and sustainable photothermal nanomaterials for solar energy harvesting applications such as water desalination.
