OBJECTIVE: To evaluate the effects that inhalation of the combustion products of the traditional Chinese herb Aiye(Folium Artemisiae Argyi) has on the central nervous system.METHODS: Forty Kunming mice(half male) were randomly assigned(n = 10/group) to a control group(C) or one of three moxa smoke concentration groups(% opacity): low(L1; 0.4%), medium(M1; 2%), and high(H1; 15%). Mice in the latter three groups were exposed to moxa smoke in a dynamic gas exposure cabinet for 20 min per day for7 days. Mice in control group were placed in the same cabinet without any intervention. For the sleep experiments, another 50 mice were divided into five groups of 10 mice each: a saline-injected control group, L1 + pentobarbital sodium(PS)-injected group, M1+PS group, H1(15%)+PS group,and a positive control group(10 mg/kg, chlorpromazine, p.o.). The weight, general activities, locomotor activities, rotarod performance, sleep duration,and sleeping rate induced by a subthreshold dose of pentobarbital sodium were recorded in the mice,and the composition of moxa smoke was analyzed using headspace gas chromatography(GC-HS).RESULTS: A low concentration of smoke significantly decreased the frequency of locomotor activities and the time for which the mice remaining on the rotarod; however, a high smoke concentration significantly prolonged the pentobarbital-induced sleeping time and sleeping rate.CONCLUSION: The concentration-dependent relaxing effects of moxa smoke on the Central Nervous System(CNS) were confirmed. Moreover, GC-HS analysis showed that the component present in the highest concentration in moxa smoke was eucalyp-tol, an essential oil well recognized for its soothing effects on the CNS. This may therefore be accountable for the sedative effects of moxa smoke. 展开更多

Phase engineering of molybdenum disulfide(MoS_(2))can achieve phase transformation from the semiconducting phase(2H-MoS_(2))with poor conductivity to the metallic phase(1T-MoS_(2))with superior electrochemical properties.Therefore,it is desirable to prepare high concentration 1T-MoS_(2)by simple and facile methods.In this work,MoS_(2)with high concentration of 1T phase is successfully prepared by one-pot hydrothermal synthesis through the synergistic effect of HNO_(3)and CH_(3)CH_(2)OH,which is stable for more than half of a year.The as-synthesized MoS_(2)shows high capacitance of 392Fg^(-1)at 1A g^(-1)as used for supercapacitors electrodes,and displays excellent capacitance retention(83%after 10,000 cycles).Asymmetric supercapacitors(ASCs)devices assembled by the as-synthesized MoS_(2)and MnO_(2)on carbon cloths,exhibit high energy and power densities(0.194 m Wh cm^(-2)and 13.466 mW cm^(-2)).These results shed a light to realize 1T phase MoS_(2)through the synergistic effect in hydrothermal processing. 展开更多

To address the problems of low accuracy by the CONWEP model and poor efficiency by the Coupled Eulerian-Lagrangian(CEL)method in predicting close-range air blast loads of cylindrical charges,a neural network-based simulation(NNS)method with higher accuracy and better efficiency was proposed.The NNS method consisted of three main steps.First,the parameters of blast loads,including the peak pressures and impulses of cylindrical charges with different aspect ratios(L/D)at different stand-off distances and incident angles were obtained by two-dimensional numerical simulations.Subsequently,incident shape factors of cylindrical charges with arbitrary aspect ratios were predicted by a neural network.Finally,reflected shape factors were derived and implemented into the subroutine of the ABAQUS code to modify the CONWEP model,including modifications of impulse and overpressure.The reliability of the proposed NNS method was verified by related experimental results.Remarkable accuracy improvement was acquired by the proposed NNS method compared with the unmodified CONWEP model.Moreover,huge efficiency superiority was obtained by the proposed NNS method compared with the CEL method.The proposed NNS method showed good accuracy when the scaled distance was greater than 0.2 m/kg^(1/3).It should be noted that there is no need to generate a new dataset again since the blast loads satisfy the similarity law,and the proposed NNS method can be directly used to simulate the blast loads generated by different cylindrical charges.The proposed NNS method with high efficiency and accuracy can be used as an effective method to analyze the dynamic response of structures under blast loads,and it has significant application prospects in designing protective structures. 展开更多

Objective Patients with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection frequently develop central nervous system damage,yet the mechanisms driving this pathology remain unclear.This study investigated the primary pathways and key factors underlying brain tissue damage induced by the SARS-CoV-2 beta variant(lineage B.1.351).Methods K18-hACE2 and C57BL/6 mice were intranasally infected with the SARS-CoV-2 beta variant.Viral replication,pathological phenotypes,and brain transcriptomes were analyzed.Gene Ontology(GO)analysis was performed to identify altered pathways.Expression changes of host genes were verified using reverse transcription-quantitative polymerase chain reaction and Western blot.Results Pathological alterations were observed in the lungs of both mouse strains.However,only K18-hACE2 mice exhibited elevated viral RNA loads and infectious titers in the brain at 3 days post-infection,accompanied by neuropathological injury and weight loss.GO analysis of infected K18-hACE2 brain tissue revealed significant dysregulation of genes associated with innate immunity and antiviral defense responses,including type I interferons,pro-inflammatory cytokines,Toll-like receptor signaling components,and interferon-stimulated genes.Neuroinflammation was evident,alongside activation of apoptotic and pyroptotic pathways.Furthermore,altered neural cell marker expression suggested viral-induced neuroglial activation,resulting in caspase 4 and lipocalin 2 release and disruption of neuronal molecular networks.Conclusion These findings elucidate mechanisms of neuropathogenicity associated with the SARS-CoV-2 beta variant and highlight therapeutic targets to mitigate COVID-19-related neurological dysfunction. 展开更多

This paper investigates the active traveling wave vibration control of an elastic supported rotating porous aluminium conical shell(CS)under impact loading.Piezoelectric smart materials in the form of micro fiber composites(MFCs)are used as actuators and sensors.To this end,a metal pore truncated CS with MFCs attached to its surface is considered.Adding artificial virtual springs at two edges of the truncated CS achieves various elastic supported boundaries by changing the spring stiffness.Based on the first-order shear deformation theory(FSDT),minimum energy principle,and artificial virtual spring technology,the theoretical formulations considering the electromechanical coupling are derived.The comparison of the natural frequency of the present results with the natural frequencies reported in previous literature evaluates the accuracy of the present approach.To study the vibration control,the integral quadrature method in conjunction with the differential quadrature approximation in the length direction is used to discretize the partial differential dynamical system to form a set of ordinary differential equations.With the aid of the velocity negative feedback method,both the time history and the input control voltage on the actuator are demonstrated to present the effects of velocity feedback gain,pore distribution type,semi-vertex angle,impact loading,and rotational angular velocity on the traveling wave vibration control. 展开更多

According to folk usage of Aconitum carmichaelii Debx., the present study was designed to determine the feasibility of the stems and leaves of Aconitum carmichaelii Debx. as a new medicinal resource. Fourteen alkaloids in mother roots, fibrous roots, stems, and leaves of Aconitum carmichaelii Debx. were measured by HPLC-MS/MS. And multivariate analysis methods, such as clustering analysis and principal component analysis, were applied to analyze the difference among various parts. In addition, the acute toxicity, analgesia, and anti-inflammatory tests were carried out. The results suggested that the contents of alkaloids in mother roots and fibrous roots were approximate, but those of leaves and stems were different from mother roots and fibrous roots. The results of the acute toxicity testing demonstrated the toxicity of fibrous root was strongest, and mother roots were slightly less toxic than fibrous roots. The stems and leaves were far less toxic than mother and fibrous roots. In addition, the analgesia and inflammatory tests showed the effects of the various tissues had no difference each other. These results provided a basis for developing new complementary and alternative treatments for rheumatoid arthritis patients. Simultaneously, the approach may also turn wastes into treasure and promote the development of circular economy. 展开更多

According to the characteristics of comprehensive mechanized heading face, established the mathematical model of single-phase air flow with κ-ε two equations model, and have established κ-ε-θ-κp mathematic model to solve two-phase flow of gas and particles in dust space with eulerian-eulerian method and eulerian-lagrangian method. Numerical solution of gas-particle two-phase flow was put forward based on collocated grid SIMPLE algorithm. Moreover, numerical simulation of dust concentration in fully mechanized caving face was carded out by using Fluent software. Finally, when in forced-exhaust ventilation circumstance, drawer type fan drum have less dust absorption, and most of dust spread to the other site; the dust concentration is inversely proportional to the distance from tunneling head, and the dust concentration has already diffused to decrease below 102 mg/m3 at the position ofx=12 m. Dust are more focused on relative side(in the range about y from 0 to 2 meter) of roadway space of press-ventilated fan drum, especially between tunneling place and drawer type fan drum; the roadway with road header have a higher dust concentration. These conclusions provide reliable theory basis for the dust prevention in comprehensive mechanized heading face. 展开更多

A self-healing and recyclable carbon tube/epoxy adhesive was prepared by epoxy monomer with Diels-Alder (DA) bonds, diethylenetriamine and polyethyleneimine modified multi-wall carbon nanotubes (MWCNTs). The self-healing and recyclable ability was attained by thermally reversible Diels-Alder reaction between furan and maleimide in the epoxy monomer. By controlling the molar ratio of furfuryl glycidyl ether and 4,4'-methylenebis(N-phenylmaleimide), the glass transition temperature and mechanical properties of MWCNTs/epoxy adhesives were varied. The self-healing properties of MWCNTs/epoxy polymers were evaluated by lap shear experiment and the results showed that the MWCNTs/epoxy adhesives exhibited enhanced mechanical properties and excellent self-healing ability under heat stimulus. The healing efficiency was related to the molecule mobility and the conversion of DA reaction between furan and maleimide. The MWCNTs/epoxy adhesives also displayed excellent recyclable ability by transforming into soluble polymer under heating. These materials offer a wide range of possibilities to produce materials with healing and recyclable ability and have the potential to bring great benefits to our daily lives by enhancing the safety, performance, and lifetime of products. 展开更多

BACKGROUND Liver failure has high mortality and poor prognosis,and establishing new reliable markers for predicting its prognosis is necessary.Mucosal-associated invariant T(MAIT)cells are a novel population of innate-like lymphocytes involved in inflammatory liver disease,and their potential role in liver failure remains unclear.AIM To investigate alteration of circulating MAIT cells and assess its prognostic value in patients with hepatitis B virus(HBV)-related liver failure.METHODS We recruited 55 patients with HBV-related liver failure,48 patients with chronic hepatitis B and 40 healthy controls(HCs)from Nantong Third People’s Hospital Affiliated to Nantong University.Peripheral blood mononuclear cells were isolated,and the percentage and number of circulating MAIT cells were detected by flow cytometry.Plasma levels of interleukin(IL)-7,IL-12p70,IL-18 and interferon-αwere measured by Luminex assay.RESULTS Circulating MAIT cells were significantly decreased in HBV-related liver failure patients(percentage:2.00±1.22 vs 5.19±1.27%,P<0.0001;number:5.47±4.93 vs 84.43±19.59,P<0.0001)compared with HCs.More importantly,there was a significant reduction of MAIT cells in patients with middle/late-stage compared with early-stage liver failure.Circulating MAIT cells partially recovered after disease improvement,both in percentage(4.01±1.21 vs 2.04±0.95%,P<0.0001)and in cell count(17.24±8.56 vs 7.41±4.99,P<0.0001).The proportion(2.29±1.01 vs 1.58±1.38%,P<0.05)and number(7.30±5.70 vs 2.94±1.47,P<0.001)of circulating MAIT cells were significantly higher in the survival group than in the dead/liver transplantation group,and the Kaplan–Meier curve showed that lower expression of circulating MAIT cells(both percentage and cell count)predicted poor overall survival(P<0.01).Also,the levels of IL-12(20.26±5.42 pg/mL vs 17.76±2.79 pg/mL,P=0.01)and IL-18(1470.05±1525.38 pg/mL vs 362.99±109.64 pg/mL,P<0.0001)were dramatically increased in HBV-related liver failure patients compared with HCs.CONCLUSION Circulating MAIT cells may play an important role in the process of HBV-related liver failure and can be an important prognostic marker. 展开更多

Developing wheat that acquires and uses phosphorus(P)more efficiently is a promising and low-cost solution for increasing grain yield and reducing P-related environmental impacts.The present study identified agronomic and physiological traits that contribute to genetic variation in the P acquisition,remobilization,and utilization efficiency of 11 wheat cultivars from southwest China grown in P-deficient purple lithomorphic soil(Olsen P=4.7)with balanced(75 kg P ha^(−1))and excess P(120 kg P ha^(−1))supplies.On average,soil P deficiency(–P)reduced root P uptake(17.0%–60.8%),P remobilization(33.9%–52.8%),dry mass yield(11.5%–39.2%),and grain yield(17.7%–54.4%).Balanced P(+P)increased grain yield via increased plant biomass rather than increased HI.–P increased phosphorus uptake efficiency(PUpE,4.5-fold),phosphorus utilization efficiency(PUtE,1.25-fold),and phosphorus use efficiency(PUE,5.4-fold)compared with those under+P,and PUtE explained most(58.1%–60.8%)of the genetic variation in PUE under both–P and+P.The high root P uptake of P-efficient cultivars under–P was regulated by root surface area and root length density in the 0–10 cm soil layer but not in the 10–20 and 20–40 cm soil layers,suggesting that a topsoil foraging strategy is a more economical approach than deeper root exploration for increasing P uptake.Root P uptake before anthesis and P remobilization after anthesis were critical for increasing the PUtE of wheat,given that P-efficient cultivars showed higher Pn(net photosynthetic rate)and sucrose levels than P-inefficient cultivars.Pn reduction by–P resulted from decreased Gs and Ci,and high evapotranspiration under+P increased shoot P%by increasing root P uptake.Genetic variation in the source-to-sink ratio was observed in consequence of a+P-induced allometric increase in sucrose in leaves and kernels.Owing to these beneficial effects,+P increased the kernel N and P yields of the 11 cultivars by 9.9%–52.4%and 12.3%–48.8%,respectively.The findings of this study could help improve wheat in future breeding efforts and P management by identifying desirable Pefficient phenotypes in P-deficient farming systems. 展开更多

The inferior conductivity and drastic volume expansion of silicon still remain the bottleneck in achieving high energy density Lithium-ion Batteries(LIBs).The design of the three-dimensional structure of electrodes by compositing silicon and carbon materials has been employed to tackle the above challenges,however,the exorbitant costs and the uncertainty of the conductive structure persist,leaving ample room for improvement.Herein,silicon nanoparticles were innovatively composited with eco-friendly biochar sourced from cotton to fabricate a 3D globally consecutive conductive network.The network serves a dual purpose:enhancing overall electrode conductivity and serving as a scaffold to maintain electrode integrity.The conductivity of the network was further augmented by introducing P-doping at the optimum doping temperature of 350℃.Unlike the local conductive sites formed by the mere mixing of silicon and conductive agents,the consecutive network can affirm the improvement of the conductivity at a macro level.Moreover,first-principle calculations further validated that the rapid diffusion of Li^(+)is attributed to the tailored electronic microstructure and charge rearrangement of the fiber.The prepared consecutive conductive Si@P-doped carbonized cotton fiber anode outperforms the inconsecutive Si@Graphite anode in both cycling performance(capacity retention of 1777.15 mAh g^(-1) vs.682.56 mAh g^(-1) after 150 cycles at 0.3 C)and rate performance(1244.24 mAh g^(-1) vs.370.28 mAh g^(-1) at 2.0 C).The findings of this study may open up new avenues for the development of globally interconnected conductive networks in Si-based anodes,thereby enabling the fabrication of high-performance LIBs. 展开更多
