Self-assembly is the combination of active ingredients into aggregates through noncovalent bonds, such as hydrogen bonding, electrostatic interactions, ionic interactions, and hydrophobic interactions. The complex properties and special structures of CMM components create the basis for selfassembly. The self-assembled materials formed after CMM compatibility is an important part of the material basis for the efficacy of TCM, which can help explain the scientific connotations of CMM compatibility. This review summarizes the self-assembly phenomenon from the perspective of drug pair combinations in recent decades and explains the scientific connotation of CMM compatibility about the material basis, pharmacodynamic changes, and mechanism of action, providing new ideas and methods for the study of TCM.展开更多

文摘Grafting is widely used in cucumbers to enhance their tolerance to environmental stress.Compatibility is a key factor for successful grafting,however,the physiological mechanisms that affect grafting compatibility are not clear.This study aimed to investigate the physiological mechanism underlying cucumber/pumpkin grafting compatibility.Two pumpkin cultivars with significant differences in compatibility,Figleaf gourd(compatible rootstock,Cf)and Dongyangshenli(incompatible rootstock,Cmo),were used as rootstocks.Three cucumber cultivars with different growth rates were used as scions,including cucumber‘Shenluchunsi’(strong growth,V1),‘Cuilü’(weak growth,V2),and‘Liangyoulüjian 102’(medium growth,V3).Six grafting combinations(V1/Cf,V2/Cf,V3/Cf,V1/Cmo,V2/Cmo,and V3/Cmo)were used to analyze the effect of scion and rootstock varieties,as well as the chemical composition of the exudate from the stem cutting surface,on the compatibility of grafted plants.Here,we found that rootstock was closely correlated with the compatibility of cucumber/pumpkin grafted plants.The sucrose content in the exudate of the stem,enzyme activity,and the expression of genes related to sucrose biosynthesis in Cmo were significantly higher than those in Cf.Correlation analysis showed that the sucrose content difference between the exudate of rootstock and scion stems was negatively correlated with graft compatibility.Exogenous treatment with a 0.5%sucrose solution on the scions significantly reduced the difference in sucrose content between rootstock and scion and enhanced graft survival rate in the incompatible combination.The stem segment grafting experiment in vitro found that the high difference in sucrose concentration between the rootstock and scion decreased the grafting compatibility of cucumber/pumpkin by reducing the adhesion of the cutting surface.Taken together,the higher sucrose concentration difference between rootstock and scion decreased the adhesion of the cutting surface,resulting in the incompatibility of cucumber/pumpkin grafted plants.

文摘Background The pink bollworm(Pectinophora gossypiella,PBW)is a major cotton pest,causing economic losses by damaging seeds and fiber.Cotton growers typically use systemic and broad-spectrum insecticides for its manage-ment,which pose risks to human health and the environment.Consequently,there is a need for eco-friendly alterna-tives.This study evaluates the bio-efficacy of the entomopathogenic fungus Metarhizium anisopliae strain TMBMA1 against pink bollworm and assesses its compatibility with major insecticides.Additionally,to comprehend the dynam-ics of colonization and the infection processes of entomopathogenic fungi(EPF),scanning electron microscopy(SEM)of infected larvae was carried out.Result We challenged the second instar PBW larvae to eight different concentrations(1×10^(3) to 1×10^(10) conidia mL^(-1))of an M.anisopliae strain TMBMA1.The highest mortality(100%)occurred at the higher concentrations i.e.,1×109 and 1×10^(10) spores mL^(-1),while the lowest mortality rate(46.6%)was observed at 1×10^(3) spores mL^(-1) con-centration compared to control(3.33%).TMBMA1’s biocontrol efficacy was validated by Probit analysis,exhibiting an exceptionally low median lethal concentration(LC50)value of 7.1×10^(5).The comparative evaluation revealed that the M.anisopliae strain TMBMA1 performed excellently with insecticide[Cypermethrin 10%(volume fraction)emulsifiable concentrate(EC)at 1 mL·L^(-1) water]giving 100%mortality,both being superior to a commercial prod-uct of M.anisopliae(60%).According to SEM analysis,the EPF strain was profusely colonized on both the internal and external surfaces of PBW larvae.Compatibility studies with insecticides revealed>98%and>96%reduction in the sporulation of M.anisopliae due to the treatment of Emamectin Benzoate 1.5%(mass fraction)+Profenofos 35%(mass fraction)water dispersible granules(WDG)and Profenofos 50%EC,respectively.In contrast,Cypermethrin 10%EC,Emamectin Benzoate 5%(mass fraction)Soluble Granules and Neem Seed Kernel Extract(NSKE)0.15%(volume fraction)treatments reported lower reduction(11.45%,13.79%and 21.21%respectively)in spore production.Conclusion According to the current investigations,the M.anisopliae strain TMBMA1 exhibits high virulence against PBW and offers a promising eco-friendly solution for managing this pest.It shows significant potential to pro-liferate on both external and internal surfaces of PBW.This strain can be integrated into PBW management programs with chemical insecticides,improving pest control and lessening environmental impact.

文摘Enhancing rubber-bitumen compatibility is crucial to improve pavement performance and durability.To investigate the compatibility improvement between H2O2-activated waste crumb rubber(AWCR)and bitumen,coarse and fine waste crumb rubber(WCR)were treated and analyzed through multi-scale characterization and molecular simulation.Microstructure and chemical changes of WCR and AWCR were analyzed with scanning electron microscope(SEM),contact angle tests and Fourier transform infrared spectroscopy(FTIR).Compatibility was also indirectly evaluated through modified boiling tests and storage stability tests.Besides,molecular dynamics was used to explore the interaction between WCR/AWCR and bitumen.SEM,contact angle,and FTIR results showed bond breakage of C=C and C–C and increased polar groups like–OH and–COOH in AWCR,resulting in a rougher texture and higher surface energy.Compared with WCR,AWCR showed a lower bitumen stripping rate after boiling,and the binder with AWCR also had a lower softening point difference and segregation rate after storage.Molecular dynamics simulations further confirmed that AWCR has a closer solubility parameter and higher binding energy to bitumen than WCR,reflected in a relatively slower diffusion rate.This study provides comprehensive evidence for an eco-friendly method of WCR surface treatment for more efficient recycling of tire rubber in asphalt pavements.

文摘Objective This study aimed to study the effects of different crystalline states of Sheng Shigao(raw gypsum,RG)and its inorganic elements on the antipyretic efficacy of Baihu Decoction(BHT).Methods RG samples calcined at different temperatures were prepared.The phase composition of RG and Duan Shigao(calcination of gypsum,CG)as well as the changes in phase composition before and after adding water to RG calcined at specific temperatures,were determined using X-ray diffraction(XRD).A fever model was established by subcutaneously injecting 20%yeast suspension(10 mL·kg~(-1))into the backs of rats.The effects of BHT containing RG in different crystalline states on rat body temperature were measured.Serum levels of IL-1β,IL-6,and hypothalamic prostaglandin E2(PGE_2)were detected using ELISA.Serum Ca~(2+)levels were measured using a microplate method.The content of trace elements in RG and CG and the corresponding freeze-dried BHT powder was determined using inductively coupled plasma mass spectrometry(ICP-MS).The complexation of representative inorganic elements with mangiferin,a major active component in BHT,was investigated using UV-Vis spectroscopy and fluorescence spectroscopy.A validation model was established using RAW264.7 mouse macrophages.Drug-containing serum of BHT with different inorganic elements was prepared,and the nitric oxide(NO)levels in the cell supernatant of different treatment groups were measured using the Griess method.The mRNA levels of IL-6,TNF-α,and PGE2in each group were detected using qPCR(real-time fluorescent quantitative PCR).Results After calcination,the phase composition of RG changed,and the content of inorganic elements in RG,CG170(RG calcined at 170°C),and CG350(RG calcined at 350°C)showed similar trends.Compared with RG,the content of Ca,Sr,Al,and Na in CG changed significantly.Compared with BHT,the content of Ca,Sr,Si,and Na in CG changed significantly when incorporated into the formula.Intermolecular interactions confirmed strong binding between mangiferin and Cu~(2+)and Al~(3+).Cu~(2+)and Fe~(3+)exhibited fluorescence quenching effects on mangiferin solution,while Al~(3+)and Zn~(2+)showed strong fluorescence enhancement,with fluorescence intensity increasing by 120-fold and 30-fold,respectively.In vitro evaluation of synergistic anti-inflammatory effects confirmed that Ca,Fe,Cr,Al,and Si exhibited synergistic anti-inflammatory effects.Conclusion The crystalline state of RG has little effect on its antipyretic properties,while Ca,Sr,Na,Fe,and Al are likely the key material bases influencing its efficacy.

文摘Block-flexure toppling constitutes the predominant form of toppling failure in rock slopes.Although it has been extensively studied,the current theoretical models are often oversimplified by treating rock layers as rigid bodies that diverge from actual conditions.The proposed Equivalent Deformation Compatibility Method(EDCM)offers a fresh approach to assess the stability of rock slopes prone to block-flexure toppling.EDCM posits that blocky rock layers,with their inability to withstand significant bending and role in merely transferring forces,can be modeled as intact layers with a reduced modulus.The method simplifies the complex issue of analyzing discrete and continuous rock layers to the study of layered soft and hard rock,establishing deformation compatibility equations subsequently.Validation of the EDCM was achieved through numerical models,physical model testing,and application to an actual slope.The factor of safety(FS)for slopes corresponds with the results from both models and the actual slope,demonstrating the method's applicability for evaluating susceptibility to block-flexure toppling.When applying the EDCM,it is advised to set the elastic modulus reduction coefficient for blocky layers at a value below 0.1.

文摘All-solid-state batteries(ASSBs)assembled with sulfide solid electrolytes(SSEs)and nickel(Ni)-rich oxide cathode materials are expected to achieve high energy density and safety,representing potential candidates for the next-generation energy storage systems.However,interfacial issues between SSEs and Nirich oxide cathode materials,attributed to space charge layer,interfacial side reactions,and mechanical contact failure,significantly restrict the performances of ASSBs.The interface degradation is closely related to the components of the composite cathode and the process of electrode fabrication.Focusing on the influencing factors of interface compatibility between SSEs and Ni-rich oxide cathode,this article systematically discusses how cathode active materials(CAMs),electrolytes,conductive additives,binders,and electrode fabrication impact the interface compatibility.In addition,the strategies for the compatibility modification are reviewed.Furthermore,the challenges and prospects of intensive research on the degradation and modification of the SSE/Ni-rich cathode material interface are discussed.This review is intended to inspire the development of high-energy-density and high-safety all-solid-state batteries.

文摘The initial stresses widely exist in elastic materials.While achieving a continuum stress-free configuration through compatible unloading is desirable,mechanical unloading alone frequently proves insufficient,posing challenges in avoiding virtual stress-free configurations.In this paper,we introduce a novel concept of equivalent temperature variation to counteract the incompatible initial strain.Our focus is on initially stressed cylindrical and spherical elastomers,where we first derive the Saint-Venant,Beltrami-Michell,and Volterra integral conditions in orthogonal curvilinear coordinates using the exterior differential form theory.It is shown that for any given axially or spherically distributed initial stress,an equivalent temperature variation always exists.Furthermore,we propose two innovative initial stress forms based on the steady-state heat conduction.By introducing an equivalent temperature variation,the initial stress can be released through a compatible thermo-mechanical unloading process,offering valuable insights into the constitutive theory of initially stressed elastic materials.

文摘Ulcerative colitis(UC)is a chronic and non-specific inflammatory bowel disease(IBD).Huanglian Ganjiang decoction(HGD),derived from ancient book Beiji Qianjin Yao Fang,has demonstrated efficacy in treating UC patients traditionally.Previous research established that the compatibility of cold herb Coptidis Rhizoma+Phellodendri Chinensis Cortex(CP)and hot herb Angelicae Sinensis Radix+Zingiberis Rhizoma(AZ)in HGD synergistically improved colitis mice.This study investigated the compatibility mechanisms through which CP and AZ regulated inflammatory balance in colitis mice.The experimental colitis model was established by administering 3%dextran sulphate sodium(DSS)to mice for 7 days,followed by CP,AZ and CPAZ treatment for an additional 7 days.M1/M2 macrophage polarization levels,glucose metabolites levels and pyruvate dehydrogenase kinase 4(PDK4)expression were analyzed using flow cytometry,Western blot,immunofluorescence and targeted glucose metabolomics.The findings indicated that CP inhibited M1 macrophage polarization,decreased inflammatory metabolites associated with tricarboxylic acid(TCA)cycle,and suppressed PDK4 expression and pyruvate dehydrogenase(PDH)(Ser-293)phosphorylation level.AZ enhanced M2 macrophage polarization,increased lactate axis metabolite lactate levels,and upregulated PDK4 expression and PDH(Ser-293)phosphorylation level.TCA cycle blocker AG-221 and adeno-associated virus(AAV)-PDK4 partially negated CP’s inhibition of M1 macrophage polarization.Lactate axis antagonist oxamate and PDK4 inhibitor dichloroacetate(DCA)partially reduced AZ’s activation of M2 macrophage polarization.In conclusion,the compatibility of CP and AZ synergistically alleviated colitis in mice through M1/M2 macrophage polarization balance via PDK4-mediated glucose metabolism reprogramming.Specifically,CP reduced M1 macrophage polarization by restoration of TCA cycle via PDK4 inhibition,while AZ increased M2 macrophage polarization through activation of PDK4/lactate axis.

文摘A personalized outfit recommendation has emerged as a hot research topic in the fashion domain.However,existing recommendations do not fully exploit user style preferences.Typically,users prefer particular styles such as casual and athletic styles,and consider attributes like color and texture when selecting outfits.To achieve personalized outfit recommendations in line with user style preferences,this paper proposes a personal style guided outfit recommendation with multi-modal fashion compatibility modeling,termed as PSGNet.Firstly,a style classifier is designed to categorize fashion images of various clothing types and attributes into distinct style categories.Secondly,a personal style prediction module extracts user style preferences by analyzing historical data.Then,to address the limitations of single-modal representations and enhance fashion compatibility,both fashion images and text data are leveraged to extract multi-modal features.Finally,PSGNet integrates these components through Bayesian personalized ranking(BPR)to unify the personal style and fashion compatibility,where the former is used as personal style features and guides the output of the personalized outfit recommendation tailored to the target user.Extensive experiments on large-scale datasets demonstrate that the proposed model is efficient on the personalized outfit recommendation.

文摘Background:Panacis Quinquefolii Radix(PQR)is known for its ability to nourish“Qi”(it serves as the driving force for the functional activities of the body’s organs and meridians,promoting and regulating various physiological functions)and“Yin”(it represents the material foundation of the human body.It plays a role in nourishing,moistening,and cooling the body).Notoginseng Radix et Rhizoma(NRR)is recognized for its properties of resolving blood stasis(it refers to a pathological condition characterized by impaired or stagnant blood circulation within the body).Changes in the compatibility ratio of these herbs often lead to variations in their chemical composition and efficacy.However,the specific alterations in chemical composition and efficacy resulting from compatibility adjustments remain unclear.We aimed to compare the material basis and their effects of different compatibility ratios of PQR and NRR on“Qi”deficiency and blood stasis syndrome(QBS).Methods:This study employed UPLC-Q/TOF-MS to identify effective compounds in the compatibility of PQR and NRR and utilized UPLC-TQ-MS/MS to analyze the dissolution of 16 saponins in PQR and NRR at 9 different ratios.A rat model of QBS was established,and the efficacy of PQR and NRR in treating this syndrome was assessed using hemorheology and coagulation analyses.Results:The study results show that PQR and NRR exhibit significant efficacy,effectively reducing blood viscosity induced by platelet aggregation and lowering inflammatory markers such as IL-6,IL-10,TXB2 and ET associated with vascular injury.Moreover,this combination regulates ATP and ADP levels,enhances energy metabolism,and promotes overall health.A total of 104 compounds in the compatibility of PQR and NRR were identified.The ratios of 1:2 and 1:3 showed the highest total saponin content,but the ratio of 1:1 demonstrated a superior pharmacological effect for the treatment of QBS.Conclusion:In summary,the compatibility of PQR and NRR not only shows the complex interactions between traditional Chinese medicinal materials,but also provides a new idea and method for the treatment of QBS.

文摘The phase volume fraction has an important role in the match of the strength and plasticity of dual phase steel.The different bainite contents(18–53 vol.%)in polygonal ferrite and bainite(PF+B)dual phase steel were obtained by controlling the relaxation finish temperature during the rolling process.The effect of bainite volume fraction on the tensile deformability was systematically investigated via experiments and crystal plasticity finite element model(CPFEM)simulation.The experimental results showed that the steel showed optimal strain hardenability and strength–plasticity matching when the bainite reached 35%.The 3D-CPFEM models with the same grain size and texture characters were established to clarify the influence of stress/strain distribution on PF+B dual phase steel with different bainite contents.The simulation results indicated that an appropriate increase in the bainite content(18%–35%)did not affect the interphase strain difference,but increased the stress distribution in both phases,as a result of enhancing the coordinated deformability of two phases and improving the strength–plasticity matching.When the bainite content increased to 53%,the stress/strain difference between the two phases was greatly increased,and plastic damage between the two phases was caused by the reduction of the coordinated deformability.

文摘Due to its synergistic effects and reduced side effects,combination therapy has become an important strategy for treating complex diseases.In traditional Chinese medicine(TCM),the“monarch,minister,assistant,envoy”compatibilities theory provides a systematic framework for drug compatibility and has guided the formation of a large number of classic formulas.However,due to the complex compositions and diverse mechanisms of action of TCM,it is difficult to comprehensively reveal its potential synergistic patterns using traditional methods.Synergistic prediction based on molecular compatibility theory provides new ideas for identifying combinations of active compounds in TCM.Compared to resource-intensive traditional experimental methods,artificial intelligence possesses the ability to mine synergistic patterns from multi-omics and structural data,providing an efficient means for modeling and optimizing TCM combinations.This paper systematically reviews the application progress of AI in the synergistic prediction of TCM active compounds and explores the challenges and prospects of its application in modeling combination relationships,thereby contributing to the modernization of TCM theory and methodological innovation.

文摘Developing advanced stealth devices to cope with radar-infrared(IR)fusion detection and diverse application scenarios is increasingly demanded,which faces significant challenges due to conflicting microwave and IR cloaking mechanisms and functional integration limitations.Here,we propose a multiscale hierarchical structure design,integrating wrinkled MXene IR shielding layer and flexible Fe_(3)O_(4)@C/PDMS microwave absorption layer.The top wrinkled MXene layer induces the intensive diffuse reflection effect,shielding IR radiation signals while allowing microwave to pass through.Meanwhile,the permeable microwaves are assimilated into the bottom Fe_(3)O_(4)@C/PDMS layer via strong magneto-electric synergy.Through theoretical and experimental optimization,the assembled stealth devices realize a near-perfect stealth capability in both X-band(8–12 GHz)and long-wave infrared(8–14μm)wavelength ranges.Specifically,it delivers a radar cross-section reduction of−20 dB m^(2),a large apparent temperature modulation range(ΔT=70℃),and a low average IR emissivity of 0.35.Additionally,the optimal device demonstrates exceptional curved surface conformability,self-cleaning capability(contact angle≈129°),and abrasion resistance(recovery time≈5 s).This design strategy promotes the development of multispectral stealth technology and reinforces its applicability and durability in complex and hostile environments.

文摘Chinese materia medica(CMM) compatibility is one core content in the theory of Traditional Chinese Medicine(TCM), and elaborating the scientific connotation of CMM compatibility is of great significance to promote the modernization of TCM. Self-assembly is the combination of active ingredients into aggregates through noncovalent bonds, such as hydrogen bonding, electrostatic interactions, ionic interactions, and hydrophobic interactions. The complex properties and special structures of CMM components create the basis for selfassembly. The self-assembled materials formed after CMM compatibility is an important part of the material basis for the efficacy of TCM, which can help explain the scientific connotations of CMM compatibility. This review summarizes the self-assembly phenomenon from the perspective of drug pair combinations in recent decades and explains the scientific connotation of CMM compatibility about the material basis, pharmacodynamic changes, and mechanism of action, providing new ideas and methods for the study of TCM.

文摘Modifying agents 2,2-Bis(4-glycidyloxyphenyl)propane(2BPE)and dibutyl phthalate(DBP)were selected to enhance the compatibility.By using molecular simulation software(Materials Studio,MS),nine systems were constructed,including molecular models of aged asphalt and WVO monomers with 2BPE and/or DBP.The solubility parameters,Flory-Huggins parameters,and interaction energies of these systems were calculated to determine the impact of 2BPE and DBP on the compatibility of WVO and aged asphalt.Results showed that the addition of 2BPE and DBP reduced the difference in the solubility parameters between WVO and aged asphalt,thus improving the compatibility between WVO and aged asphalt.Additionally,using a combination of 2BPE and DBP in both aged asphalt and rejuvenator was found to be more effective than using either 2BPE or DBP alone.Finally,it was determined that evaluating the compatibility of WVO and aged asphalt using Van der Waals potential and non-bonding energy as evaluation indicators was more accurate than using electrostatic potential energy.
