Quasi-periodic solutions with multiple base frequencies exhibit the feature of 2π-periodicity with respect to each of the hyper-time variables.However,it remains a challenge work,due to the lack of effective solution methods,to solve and track the quasi-periodic solutions with multiple base frequencies until now.In this work,a multi-steps variable-coefficient formulation is proposed,which provides a unified framework to enable either harmonic balance method or collocation method or finite difference method to solve quasi-periodic solutions with multiple base frequencies.For this purpose,a method of alternating U and S domain is also developed to efficiently evaluate the nonlinear force terms.Furthermore,a new robust phase condition is presented for all of the three methods to make them track the quasi-periodic solutions with prior unknown multiple base frequencies,while the stability of the quasi-periodic solutions is assessed by mean of Lyapunov exponents.The feasibility of the constructed methods under the above framework is verified by application to three nonlinear systems. 展开更多

This study reports the synthesis of oleic acid sterol ester with liquid crystalline properties and its enhanced stability and UV-blocking performance through microencapsulation.Oleic acid sterol ester was synthesized via the esterification of phytosterol and oleic acid,whose structure was characterized using Fourier-transform infrared spectroscopy(FTIR)and mass spectrometry(MS).Its liquid crystalline behavior was confirmed via the polarized optical microscopy(POM),thermogravimetric analysis(TGA),differential scanning calorimetry(DSC),wide-angle X-ray scattering(WAXS),and small-angle X-ray scattering(SAXS).UV absorption tests were conducted to assess the UV-blocking performance of the oleic acid sterol ester liquid crystals.To improve the stability of its liquid crystalline structure,the oleic acid sterol ester was encapsulated into microcapsules through the emulsion polymerization.SPF measurements were performed on the sunscreen formulations containing liquid crystal microcapsules.The oleic acid sterol ester displayed cholesteric liquid crystalline behavior and strong UVA absorption,which indicates its suitability as a natural UV absorber.Microencapsulation further enhanced its stability and UV-blocking properties.SPF testing showed that the formulations with microcapsules achieved an SPF value of 7.01,which surpasses the nano titanium dioxide(SPF=6.23)and significantly outperform the unencapsulated liquid crystal formulations(SPF=2.65).This study highlights the potential of microencapsulated oleic acid sterol ester as a novel UV absorber in the sunscreen formulations,offers the enhanced stability and effective UV protection,and showcases its application potential in the innovative cosmetic products. 展开更多

Only a very small proportion of the apple is processed into juice. The aim of this work is to enhance the value of cashew apples by transforming them into jam. Specifically, the aim was first to characterize the sensory properties of cashew apple jam formulations using baobab powder as a source of pectin and then to optimise the formulations. A Box-Behken design with pH, Sugar, and Baobab as factors was used to model and characterize the jam sensory descriptors, and a multivariate analysis with SensomineR was used to characterize the jam formulations. The desirability function was used to optimise the formulations. The results show globally significant regressions at the 0.05 threshold for the sensory descriptors Gelling, Brilliance, Smell, Sweetness, and (-)Astringency, with the exception of (-)Salinity. The R2 coefficients are greater than 80%. The factors studied could have effects on the sensory descriptors of cashew jam formulations. The Baobab had the main effect on the gelling, smell, and astringency of the jams. Brilliance depended on the added sugar. A product effect (p < 0.001) was observed for the descriptors Smell, Gelling, Brilliance, and Sweetness, as these allowed the panelists to find differences between the formulations. Optimum jam formulation can be achieved with 51.56% sugar and 2.12% Baobab at a pH of 3.15. Cashew apple jam using Baobab offers opportunities to add value to apples that have long been abandoned in the field. It would be important to find conditions for prolonged storage of this jam. 展开更多

BACKGROUND Diabetic nephropathy(DN)is a major complication of diabetes,marked by progressive renal damage and an inflammatory response.Although research has investigated the pathological mechanisms underlying DN,effective treatment options remain limited.AIM To evaluate the therapeutic impact of Shenzhuo formulation(SZF)on a DN mouse model and to examine its potential molecular mechanisms using transcriptomic and metabolomic approaches.METHODS We established a DN mouse model through a high-fat diet combined with streptozotocin(STZ)injection,followed by SZF treatment.We analyzed SZF’s effects on gene expression and metabolite profiles in renal tissues of DN mice using transcriptomics and metabolomics techniques.Additionally,based on transcriptomic and non-targeted metabolomic findings,we further assessed SZF’s influence on the expression of factors related to the cytochrome P450(CYP450)-mediated arachidonic acid(AA)metabolism pathway,as well as its effects on inflammation and oxidative stress.RESULTS SZF intervention significantly decreased hyperglycemia and mitigated renal function impairment in DN mice.Pathological analysis revealed that SZF treatment improved renal tissue damage,reduced fibrosis,and diminished glycogen deposition.Transcriptomic analysis indicated that SZF influenced mRNA expression of CYP450-related genes,including Cyp2j13,Cyp2b9,Pla2 g2e/Cyp4a12a,Cyp4a32,Cyp2e1,and Cyp4a14.Non-targeted metabolomic results demonstrated that SZF altered the levels of metabolites associated with the AA metabolic pathway,including 5,6-EET,14,15-EET,phosphatidylcholine,and 20-HETE.Further experiments showed that SZF upregulated the expression of CYP4A and CYP2E proteins in renal tissue,as well as CYP2J and CYP2B proteins.Additionally,SZF significantly reduced the expression of inflammatory factors in renal tissue,enhanced antioxidant enzyme activity,and alleviated oxidative stress.CONCLUSION SZF exerts anti-inflammatory and antioxidant effects by regulating CYP450-mediated AA metabolism,leading to improved renal function and improved pathological state in DN mice. 展开更多

Background:Fuke Huahuang formulation(FHF)is widely used in the treatment of vaginitis,with clinical evidence indicating its promising anti-inflammatory properties.Methods:We explored the bioactive components and potential mechanisms of FHF for treating vaginitis,and reveal its pharmacological activities against vaginitis.Results:A total of 12 anti-inflammatory components in FHF and 584 pharmacological targets were identified.Furthermore,1427 vaginitis-associated targets were identified,and 184 intersection targets between FHF and vaginitis were constructed for network analysis.Gene Ontology and pathway analysis revealed that the therapeutical targets of FHF against vaginitis are involved in modulating inflammatory stress,enhancing immunoregulation,reconstructing the microenvironment,and suppressing cell damage.Molecular docking analysis further suggested the possible direct binding of the bioactive compounds of FHF(fumarine)to the core targets,including AKT Serine/Threonine Kinase 1(AKT1),Signal Transducer and Activator of Transcription 3(STAT3),and nuclear factor-kappaB(NF-κB).Experimental validation found that FHF-treated vaginitis rats exhibited reduced intracellular AKT1,STAT3,and NF-κB protein expressions.Conclusion:Overall,we identified the bioactive compounds and pharmacological mechanisms of FHF against vaginitis,thus offering a theoretical fundament for exploring FHF for treating vaginitis in the future. 展开更多

This work focuses on the formulation of a dietary cold sauce,mayonnaise,which combines the therapeutic properties of two basic ingredients:PSO(Pumpkin Seed Oil)and quail egg,both of which are renowned for their high functional properties.PSO is essentially made up of unsaturated fatty acids(50%to 65%)including linoleic acid,from the omega 6 family,oleic acid(20%to 50%),a monounsaturated fatty acid(omega 9),cucurbitin,phytosterols,tri-terpenes and vitamin E(3.5 mg%).The nutritional,fatty acid,vitamin and mineral compositions of the mayonnaise compared with the ingredients,the physico-chemical characteristics of the quail egg,the PSO and the tasting of the mayonnaise were determined and gave results in terms of variable contents which are recorded in Tables 2-8.The results obtained were satisfactory.Mayonnaise,a semi-solid emulsion of oil in water with viscoelastic properties due to the network formed by lipoproteins adsorbed around neighbouring drops of oil,was prepared using the ratio of quail egg and PSO 1/4.This study may offer an alternative way of making dietary sauces. 展开更多

Chinese cabbage(Brassica rapa subsp.pekinensis)is a widely cultivated vegetable crop in Asia with significant economic importance(Li et al.,2024;Yu et al.,2024).As a potyvirus with the broad host range,turnip mosaic virus(TuMV)is a major pathogen affecting Chinese cabbages,leading to severe yield losses(Li et al.,2019).Traditional control measures have shown limited efficacy,and the long-term use of chemical pesticides has led to significant issues such as environmental pollution and pathogen resistance(Samara et al.,2021;Lu et al.,2022).Biologicallyderived pesticides have garnered considerable attention owing to their eco-friendly attributes(Ayilara et al.,2023).γ-Aminobutyric acid(GABA),initially discovered in potato tubers,has been proven to regulate immune responses and enhance resistance to fungal and bacterial pathogens by modulating reactive oxygen species and stress-related hormone signals(Tarkowski et al.,2020;Wang et al.,2025).But biologically-derived agents typically face challenges such as large particle size and instability,which limit their practical application and bioavailability(Daraban et al.,2023). 展开更多

Rubber-like materials that are commonly used in structural applications are modelled using hyperelastic material models.Most of the hyperelastic materials are nearly incompressible,which poses challenges,i.e.,volumetric locking during numerical modelling.There exist many formulations in the context of the finite element method,among which the mixed displacementpressure formulation is robust.However,such a displacement-pressure formulation is less explored in meshfree methods,which mitigates the problem associated with mesh distortion during large deformation.This work addresses this issue of alleviating volumetric locking in the element-free Galerkin method(EFGM),which is one of the popular meshfree methods.A two-field mixed variational formulation using the perturbed Lagrangian approach within the EFGM framework is proposed for modelling nearly incompressible hyperelastic material models,such as Neo-Hookean and Mooney-Rivlin.Taking advantage of the meshless nature of the EFGM,this work introduces a unique approach by randomly distributing pressure nodes across the geometry,following specific guidelines.A wide spectrum of problems involving bending,tension,compression,and contact is solved using two approaches of the proposed displacement-pressure node formulation involving regular and irregular pressure node distribution.It is observed that both approaches give accurate results compared to the reference results,though the latter offers flexibility in the pressure nodal distribution. 展开更多

Previous study has shown that 10-hydroxycamptothecin(HCPT) has well-established pharmacological effects in vitro.However,its in vivo bioavailability is very poor due to various problems,which severely restricts its clinical applications.In the present study,phospholipid complex(PC) technology was employed to improve the solubility and bioavailability of HCPT.XRD data confirmed the formation of HCPT-PC.However,our previously prepared HCPT-PC is too sticky,which may result in the slow dissolution rate and negative effects on its absorption.Therefore,we prepared HCPT-PC-solid dispersion(HCPT-PC-SD)and lipid-based formulations of HCPT-PC through simple preparation process.The results showed that the dissolution rate of HCPT-PC was effectively improved by solid dispersion technology,which reached 91.73%in 45 min.Pharmacokinetic study revealed that the AUC_(0-t) of HCPT-PC-SD and HCPT-PC lipid-based formulations was effectively further increased compared with HCPT-PC.Moreover,we found that the combination of SD technology and lipid-base formulations could be a promising drug-delivery system to improve the oral bioavailability of HCPT-PC.In addition,we showed that the bioavailability of HCPT-PC lipid-base formulations was even greater than that of HCPT-PC-SD.In particular,lipid-base formulations could be prepared just by a simple method,suggesting its feasibility of industrialization. 展开更多

Aim To research the computer optimization design in material formulation. Methods The professional software including experimental design, mathematical modeling and optimization of single and multiple purposes was developed and applied to the formulation design for the flame retardant ethylenepropylene-diene mischpolymer (EPDM) insulation composites. With the aid of equipartition design, the mathematical models were established based on the optimization of the four properties (limiting oxygen index, volume resistance, tensile strength and elongation). Results The models from limited experiments had good significance, and the modeling analysis conclusions were in good agreement with later experiments. The optimization formulation was practically excellent. Conclusion The software enables practically a comprehensive multi-purpose use of material formulation research. 展开更多
