Circadian rhythm is ubiquitous in nature.Circadian clock genes such as Bmal1 and Clock form a multi-level transcription-translation feedback network,and regulate a variety of physiological and pathological processes,including bone and cartilage metabolism.Deletion of the core clock gene Bmal1 leads to pathological bone alterations,while the phenotypes are not consistent.Studies have shown that multiple signaling pathways are involved in the process of Bmal1 regulating bone and cartilage metabolism,but the exact regulatory mechanisms remain unclear.This paper reviews the signaling pathways by which Bmal1 regulates bone/cartilage metabolism,the upstream regulatory factors that control Bmal1,and the current Bmal1 knockout mouse models for research.We hope to provide new insights for the prevention and treatment of bone/cartilage diseases related to circadian rhythms. 展开更多

In this paper,a double-effect DNN-based Digital Back-Propagation(DBP)scheme is proposed and studied to achieve the Integrated Communication and Sensing(ICS)ability,which can not only realize nonlinear damage mitigation but also monitor the optical power and dispersion profile over multi-span links.The link status information can be extracted by the characteristics of the learned optical fiber parameters without any other measuring instruments.The efficiency and feasibility of this method have been investigated in different fiber link conditions,including various launch power,transmission distance,and the location and the amount of the abnormal losses.A good monitoring performance can be obtained while the launch optical power is 2 dBm which does not affect the normal operation of the optical communication system and the step size of DBP is 20 km which can provide a better distance resolution.This scheme successfully detects the location of single or multiple optical attenuators in long-distance multi-span fiber links,including different abnormal losses of 2 dB,4 dB,and 6 dB in 360 km and serval combinations of abnormal losses of(1 dB,5 dB),(3 dB,3 dB),(5 dB,1 dB)in 360 km and 760 km.Meanwhile,the transfer relationship of the estimated coefficient values with different step sizes is further investigated to reduce the complexity of the fiber nonlinear damage compensation.These results provide an attractive approach for precisely sensing the optical fiber link status information and making correct strategies timely to ensure optical communication system operations. 展开更多

Magnesium(Mg)alloys are widely used lightweight structural materials for automobiles and help reduce carbon emissions.However,their use increases the production of Mg alloy scrap,which is recycled at a much lower rate than aluminum,and its greater complexity poses challenges to existing recycling processes.Although vacuum distillation can be used to recycle Mg alloy scrap,this requires optimizing and maximizing metal recirculation,but there has been no thermodynamic analysis of this process.In this study,the feasibility and controllability of separating inclusions and 23 metal impurities were evaluated,and their distribution and removal limits were quantified.Thermodynamic analyses and experimental results showed that inclusions and impurity metals of separation coefficient lgβ_(i)≤-5,including Cu,Fe,Co,and Ni below 0.001 ppm,could be removed from the matrix.All Zn entered the recycled Mg,while impurities with-1<lgβ_(i)<-5 such as Li,Ca,and Mn severely affected the purity of the recycled Mg during the later stage of distillation.Therefore,an optimization strategy for vacuum distillation recycling:lower temperatures and higher system pressures for Zn separation in the early stage,and the early termination of the recovery process in the later stage or a continuous supply of raw melt can also prevent contamination during recycling.The alloying elements Al and Zn in Mg alloy scrap can be further recovered and purified by vacuum distillation when economically feasible,to maximize the recycling of metal resources. 展开更多

Small interfering RNAs(siRNA)provide a novel and highly specific therapy due to their ability to effectively silence target genes,to date six siRNA therapeutics are approved for clinical use.Even so,some critical challenges remain to overcome in the therapeutic application of siRNAs,with delivery issues at the forefront.Among them,endo/lysosomal barrier is one of the important but often-neglected limitations hindering the delivery of siRNA therapeutics.In this review,we summarize the promising strategies that facilitate siRNAs overcoming endo/lysosomal barriers based on the cellular uptake and intracellular transport pathways,including promoting escape once endocytosis into the endo/lysosomes and bypassing lysosomes via endosome-Golgi-endoplasmic reticulum(ER)pathway or nonendocytosis pathway,and discuss the principal considerations and the future directions of promoting endo/lysosomal escape in the development of therapeutic siRNAs. 展开更多

Small interfering RNA(siRNA),a promising revolutionary therapy,faces delivery obstacles due to its poor targeting,strong charge negativity and macromolecular nature.Clinical-approved siRNAs can now only be delivered to the liver mediated by the chemically conjugated N-acetylgalactosamine(GalNAc)ligand,the conjugate can be effectively uptaken into cells through interaction with asialoglycoprotein receptor(ASGPR)highly expressed on liver hepatocytes.To further explore an efficient non-hepatic targeted delivery strategy,in this study,we designed a delivery system that chemically conjugated p53 siRNA to renal tubular cell-targeting peptides for targeting the kidney,which was suitable for industrial transformation.Results showed that peptide-siRNA conjugate could specifically enter renal tubular epithelial cells and silence target genes.In cisplatin-induced acute kidney injury(AKI)mice,peptide-siRNA conjugate blocked the p53-mediated apoptotic pathway and alleviated renal damage.The innovative proposed system to conjugate kidney-targeting peptides with siRNA achieved the efficient kidney-targeted delivery of si RNA and provided a prospective choice for treating AKI. 展开更多

Constructing multi-dimensional hydrogen bond(H-bond)regulated single-molecule systems with multiemission remains a challenge.Herein,we report the design of a new excited-state intramolecular proton transfer(ESIPT)featured chromophore(HBT-DPI)that shows flexible emission tunability via the multidimensional regulation of intra-and intermolecular H-bonds.The feature of switchable intramolecular Hbonds is induced via incorporating several hydrogen bond acceptors and donors into one single HBT-DPI molecule,allowing the“turn on/off”of ESIPT process by forming isomers with distinct intramolecular Hbonds configurations.In response to different external H-bonding environments,the obtained four types of crystal/cocrystals vary in the contents of isomers and the molecular packing modes,which are mainly guided by the intermolecular H-bonds,exhibiting non-emissive features or emissions ranging from green to orange.Utilizing the feature of intermolecular H-bond guided molecular packing,we demonstrate the utility of this fluorescent material for visualizing hydrophobic/hydrophilic areas on large-scale heterogeneous surfaces of modified poly(1,1-difluoroethylene)(PVDF)membranes and quantitatively estimating the surface hydrophobicity,providing a new approach for hydrophobicity/hydrophilicity monitoring and measurement.Overall,this study represents a new design strategy for constructing multi-dimensional hydrogen bond regulated ESIPT-based fluorescent materials that enable multiple emissions and unique applications. 展开更多

Aqueous iron-ion batteries are regarded as one of the most promising candidates for grid applications owing to their low cost,high theoretical capacity,and excellent stability of iron in aqueous electrolytes.However,the slow Fe(de)insertion caused by the high polarity of Fe^(2+)makes it difficult to match suitable cathode materials.Herein,defect-rich MoS_(2)with abundant 1T phase is synthesized and successfully applied in aqueous iron-ion batteries.Benefit from abundant active sites generated by the heteroatom incorporation and S vacancy,as well as the highly conductive 1T phase,it can deliver a specific capacity of 123 mAh/g at a current density of 100mA/g,and demonstrates an impressive capacity retention of 88%after 600 cycles at 200mA/g.This work presents a novel pathway for the advancement of cathode materials for aqueous iron-ion batteries. 展开更多

Deepwater drilling riser is the key equipment connecting the subsea wellhead and floating drilling platform.Due to complex marine environment,vortex-induced vibration(ViV)will be generated on riser,which will induce fatigue failure and even cause unpredictable drilling accidents.Therefore,it is important to study the ViV characteristics of deepwater drilling riser and reveal the main controlling factors for ensuring the safe and efficient operation of deepwater drilling engineering.In this paper,the ViV of deepwater drilling riser is numerically simulated in time domain based on the discrete vortex method(DvM).A hydrodynamic analysis model and governing equation of VIV is proposed with considering the effect of riser motion using DVM and slice method,where the governing equation is solved by Runge-Kutta method.Model validation is performed,which verified the correctness and accuracy of the mechanical model and the solution method.On this basis,the influence of the number of control points,current velocity,riser outer diameter,shear flow and top tension on the ViV characteristics of deepwater drilling risers are discussed in detail.The results show that with the increase of current velocity,the vibration amplitude of deepwater drilling riser decreases obviously,while the vibration frequency increases gradually.However,if the outer diameter of riser increases,the vibration amplitude increases,while the vibration frequency decreases gradually.The top tension also has great influence on the VIV of riser.When the top tension is 1.25 G,the VIV is suppressed to a certain extent.This study has guiding significance for optimal design and engineering control of deepwater drilling riser. 展开更多

Common anode materials in aqueous alkaline electrolytes,such as cadmium,metal hydrides and zinc,usually suffer from remarkable biotoxicity,high cost,and serious side reactions.To overcome these problems,we develop a conjugated porous polymer(CPP)in-situ grown on reduced graphene oxide(rGO)and Ketjen black(KB),noted as C_(4)N/rGO and C_(4)N/KB respectively,as the alternative anodes.The results show that C_(4)N/rGO electrode delivers a low redox potential(−0.905 V vs.Ag/AgCl),high specific capacity(268.8 mAh g^(-1) at 0.2 A g^(-1)),ultra-stable and fast sodium ion storage behavior(216 mAh g^(-1) at 20 A g^(-1))in 2 M NaOH electrolyte.The assembled C_(4)N/rGO//Ni(OH)_(2) full battery can cycle stably more than 38,000 cycles.Furthermore,by adding a small amount of antifreeze additive dimethyl sulfoxide(DMSO)to adjust the hydrogen bonding network,the low-temperature performance of the electrolyte(0.1 DMSO/2 M NaOH)is significantly improved while hydrogen evolution is inhibited.Consequently,the C_(4)N/rGO//Ni(OH)_(2) full cell exhibits an energy density of 147.3 Wh Kg^(-1) and ultra-high cycling stability over a wide temperature range from−70 to 45℃.This work provides an ultra-stable high-capacity CPPbased anode and antifreeze electrolyte for aqueous alkaline batteries and will facilitate their practical applications under extreme conditions. 展开更多

Polyetheretherketone(PEEK)is a desirable candidate to replace conventional metal implants owing to its excellent mechanical properties.However,the intrinsic bioinertness of PEEK results in inferior or delayed osseointegration,which limits its further clinical application.To address these challenges,one leading strategy is to construct a biofunctionalized surface on PEEK that provides a coordinated osteoblastosteoclast interactions microenvironment.Herein,alendronate(ALN),a common bone absorption inhibitor,was loaded in biomedical inorganic/organic microspheres,consisting of bioactive inorganic nanohydroxyapatite core,and chitosan(CS)shell.Polydopamine(PDA)modification was employed to ensure the adherence of the microspheres to the PEEK surface.The delivery of ALN and Ca^(2+)from these microspheres simultaneously suppressed osteoclastogenesis and promoted osteogenesis,resulting in a coordinated cascade of osteoblast-osteoclast interactions crucial for the per-implant osseointegration.In vitro experiments demonstrated that the PEEK surface exhibited satisfactory biocompatibility and enhanced the proliferation and osteogenic differentiation of rat bone mesenchymal stem cells while inhibiting the osteoclast differentiation.Moreover,the in vivo rat femoral drilling model demonstrated superior osseointegration three months after implantation.By considering the bone remodeling processes,this study proposes a novel biofunctionalized PEEK surface that regulates the activities of both osteoblasts and osteoclasts to promote osseointegration. 展开更多

In this study,different types of small molecular carbon sources such as melamine,dicyandiamine,pyrocatechol,and o-phenylenediamine were used to regulate the surface structures of iron/nitrogen/carbonbased composites(Fe-N/C),which were used to activate peroxymonosulfate(PMS).The relationship between different small molecular carbon sources and the electronic structure was investigated.The characteristics of metal-carrier interaction in the Fe-N/C were clarified.As a result,there were significant differences in the degradation efficiency of catalysts prepared with different small molecular carbon sources,which was related to the types of active sites.Density functional theory(DFT)and experiments results showed that the catalyst rich in C-O-C and FeN_(x)exhibited better catalytic activity,which may be attributed to the higher adsorption energy for PMS.The main active species for catalytic degradation of ofloxacin were identified as sulfate radical(SO_(4)^(·-))and hydroxyl radical(^(·)OH)by electron paramagnetic resonance(EPR)spectra.The introduction of different small molecular carbon sources can significantly affect the distribution and electronic structure of active sites on the catalyst surface,thereby regulating the generation and migration of radicals. 展开更多

Ciphertext-Policy Attribute-Based Encryption(CP-ABE)enables fine-grained access control on ciphertexts,making it a promising approach for managing data stored in the cloud-enabled Internet of Things.But existing schemes often suffer from privacy breaches due to explicit attachment of access policies or partial hiding of critical attribute content.Additionally,resource-constrained IoT devices,especially those adopting wireless communication,frequently encounter affordability issues regarding decryption costs.In this paper,we propose an efficient and fine-grained access control scheme with fully hidden policies(named FHAC).FHAC conceals all attributes in the policy and utilizes bloom filters to efficiently locate them.A test phase before decryption is applied to assist authorized users in finding matches between their attributes and the access policy.Dictionary attacks are thwarted by providing unauthorized users with invalid values.The heavy computational overhead of both the test phase and most of the decryption phase is outsourced to two cloud servers.Additionally,users can verify the correctness of multiple outsourced decryption results simultaneously.Security analysis and performance comparisons demonstrate FHAC's effectiveness in protecting policy privacy and achieving efficient decryption. 展开更多

Prompt fission neutron spectra(PFNS)have a significant role in nuclear science and technology.In this study,the PFNS for^(239)Pu are evaluated using both differential and integral experimental data.A method that leverages integral criticality benchmark experiments to constrain the PFNS data is introduced.The measured central values of the PFNS are perturbed by constructing a covariance matrix.The PFNS are sampled using two types of covariance matrices,either generated with an assumed correlation matrix and incorporating experimental uncertainties or derived directly from experimental reports.The joint Monte Carlo transport code is employed to perform transport simulations on five criticality benchmark assemblies by utilizing perturbed PFNS data.Extensive simulations result in an optimized PFNS that shows improved agreement with the integral criticality benchmark experiments.This study introduces a novel approach for optimizing differential experimental data through integral experiments,particularly when a covariance matrix is not provided. 展开更多

This study aimed to investigate the anti-inflammatory properties and underlying molecular mechanisms of 2,4',5'-trihydroxyl-5,2'-dibromo diphenylmethanone(LM49)using a carrageenan-induced paw edema model in mice,which serves as a well-established model for acute inflammation.Mice were randomly assigned into six groups,and acute inflammation was induced by injecting 1%carrageenan solution into the paw.To elucidate the anti-inflammatory effects and mechanisms of LM49,a comprehensive approach was employed,including pathology,transcriptomics,flow cytometry,RT-qPCR,Western blotting analysis,and molecular docking analysis.The results demonstrated that LM49 exerted a significant protective effect by reducing paw edema and lowering serum levels of pro-inflammatory cytokines IL-1βand TNF-a,while concurrently elevating anti-inflammatory cytokine IL-10 levels.Transcriptomic analysis identified 453 differentially expressed genes in the LM49-treated group.KEGG and GO enrichment analyses indicated that LM49 suppressed the NF-kB signaling pathway and modulated several other immuneinflammatory pathways.Molecular docking studies identified eight key targets of LM49 within the NF-kB signaling pathway.Furthermore,Western blotting analysis confirmed that LM49 inhibited the phosphorylation of p65 and IB-αand downregulated the expression of MYD88 and TLR4 in mouse paw tissues.These findings provided a foundational understanding of the anti-inflammatory effects and molecular mechanisms of LM49,paving the way for further in-depth studies in this field. 展开更多

BACKGROUND The interplay between abnormal glucose metabolism and the progression of liver fibrosis in patients with both chronic hepatitis B(CHB)and type 2 diabetes mellitus(T2DM)remains unclear.Previous studies have suggested that the coexistence of these conditions may exacerbate liver inflammation and fibrosis;however,the impacts of dynamic changes in glucose metabolism indicators,hypoglycemic medication regimens,and glycemic control status on liver fibrosis require further elucidation.AIM To explore the effect of glycemic control on hepatic fibrosis in patients with CHB and T2DM.METHODS A total of 420 patients with CHB and T2DM admitted to the Public Health Clinical Center of Chengdu between October 2018 and January 2022 were retrospectively included and classified according to liver stiffness measurement and glycemic control for between-group comparisons.RESULTS Significant differences were observed in the alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase,AST/ALT ratio,total bilirubin,direct bilirubin,diabetes treatment program,and thrombin time values among the liver fibrosis groups(adjusted P<0.05).Significant differences in albumin and gamma-glutamyl transferase levels were observed among the groups categorized by glucose status at admission(adjusted P<0.05).A positive correlation between fasting plasma glucose(FPG)and liver stiffness measurement was found to be mediated by ALT and AST.Fibrinogen and the international normalized ratio were positively correlated with glycated hemoglobin A1c,while the fibrosis-4 score,ALT,AST/ALT ratio,type III procollagen N-terminal peptide,ferritin,and activated partial thromboplastin time were correlated with FPG at admission.Additionally,AST was positively correlated with FPG at discharge(P<0.05).CONCLUSION Specific glucose metabolic parameters,hypoglycemic agents,and glycemic control status markers are associated with hepatic fibrosis in patients with both CHB and T2DM.Close blood glucose monitoring,optimized use of hypoglycemic agents,and continuous maintenance of good glycemic control may slow the progression of liver fibrosis in patients with CHB and T2DM. 展开更多
