| 1 | Aerodynamic simulation of evacuated tube maglev trains with different streamlined designs显示文摘Based on the Navier-Stokes (N-S) equations of incompressible viscous fluids and the standard k-ε turbulence model with assumptions of steady state and two dimensional conditions, a simulation of the aerodynamic drag on a maglev train in an evacuated tube was made with ANSYS/FLOTRAN software under different vacuum pressures, blockage ratios, and shapes of train head and tail. The pressure flow fields of the evacuated tube maglev train under different vacuum pressures were analyzed, and then compared under the same blockage ratio condition. The results show that the environmental pressure of 1 000 Pa in the tube is the best to achieve the effect of aerodynamic drag reduction, and there are no obvious differences in the aerodynamic drag reduction among different streamline head shapes. Overall, the bluntshape tail and the blockage ratio of 0.25 are more efficient for drag reduction of the train at the tube pressure of 1 000 Pa. | Xuyong CHEN Lifeng ZHAO Jiaqing MA Yuansen LIU | 2012 | Journal of Modern Transportation2012，20，2： | 11 |
| 2 | 3D bioprinting of integral ADSCs-NO hydrogel scaffolds to promote severe burn wound healing显示文摘Severe burns are challenging to heal and result in significant death throughout the world.Adiposederived mesenchymal stem cells(ADSCs)have emerged as a promising treatment for fullthickness burn healing but are impeded by their low viability and efficiency after grafting in vivo.Nitric oxide(NO)is beneficial in promoting stem cell bioactivity,but whether it can function effectively in vivo is still largely unknown.In this study,we bioprinted an efficient biological scaffold loaded with ADSCs and NO(3D-ADSCs/NO)to evaluate its biological efficacy in promoting severe burn wound healing.The integral 3D-ADSCs/NO hydrogel scaffolds were constructed via 3D bioprinting.Our results shown that 3D-ADSCs/NO can enhance the migration and angiogenesis of Human Umbilical Vein Endothelial Cells(HUVECs).Burn wound healing experiments in mice revealed that 3D-ADSCs/NO accelerated the wound healing by promoting faster epithelialization and collagen deposition.Notably,immunohistochemistry of CD31 suggested an increase in neovascularization,supported by the upregulation of vascular endothelial growth factor(VEGF)mRNA in ADSCs in the 3D biosystem.These findings indicated that 3D-ADSC/NO hydrogel scaffold can promote severe burn wound healing through increased neovascularization via the VEGF signalling pathway.This scaffold may be considered a promising strategy for healing severe burns. | Yu Wu Tangzhao Liang Ying Hu Shihai Jiang Yuansen Luo Chang Liu Guo Wang Jing Zhang Tao Xu Lei Zhu | 2021 | Regenerative Biomaterials2021，8，3： | 2 |
| 3 | Insights into the mechanism of Sub3 inhibiting Fusarium moniliforme infection in maize显示文摘Fusarium moniliforme(F.moniliforme) and its secondary metabolite fumonisin pose a severe threat to food safety,and searching for effective antimicrobial agents is a focus of current research.In this study,the secondary structure of Sub3 was analyzed by circular dichroism,meanwhile,the inhibition rate of Sub3 against spores,mycelia of F.moniliforme and infected maize was studied.To explore the possible inhibition mechanisms,morphological and structural changes of spores treated with Sub3 at0,1/2 MIC(minimum inhibitory concentration) and MIC were observed by scanning electron microscopy and transmission electron microscopy;the cell wall integrity,membrane integrity,reactive oxygen species,mitochondrial membrane potential,ATP synthase activity,redox reactions,and the nuclear damage of F.moniliforme were also investigated.The results showed that Sub3 was mostly in the state of random in deionized water,while mainly showed the β-sheet structure in the hydrophobic environment of 50% Trifluoroethanol(TFE) solution,indicating that Sub3 might generate partial structure deformation when acting on the cell membrane;and its MIC on F.moniliforme spores was 0.2 g/L.Under the 1/2 MIC and MIC,the inhibition rates of Sub3 against F.moniliforme infected maize were 34.3% and75.6%,respectively.The results of inhibition mechanisms revealed that the defective pathogenicity of F.moniliforme caused by Sub3 was attributed to damages on both the cell wall and the cell membrane,which might upset balance of intracellular redox system and mitochondrial energy metabolism and trigger nucleus damage,ultimately leading to cell death.Meanwhile,Sub3 could diminished ATP synthase enzyme activity in a dose-dependent manner.The results provided direct evidence for inhibition of F.moniliforme infection of maize by Sub3,and useful knowledge applicable for food preservation. | Haojie Yang Wei Zhang Pingping Tian Bangbang Li Shan Wei Shuaibing Zhang Na Li Yangyong Lyu Yuansen Hu | 2022 | Grain & Oil Science and Technology2022，5，1： | 1 |

| 6 | Hyaluronic acid-curcumin conjugate suppresses the fibrotic functions of myofibroblasts from contractive joint by the PTGER2 demethylation显示文摘Joint contracture is a fibrotic complication induced by joint immobilization and trauma,which is characterized as excessive myofibroblast proliferation in joint capsule.The treatments of joint contracture are unsatisfied and patients are suffered from joint dysfunction.Our previous study has shown that curcumin can inhibit myofibroblast proliferation in vitro,but the major challenge is the low aqueous solubility and biological activity of curcumin.In this study,hyaluronic acid-curcumin(HA-Cur)conjugate was synthesized to suppress myofibroblasts in joint contracture.Cells were isolated from the joint capsules of joint contracture patients and induced to active myofibroblasts by transforming growth factor-b(TGF-b).The anti-fibrotic function and mechanisms of HA-Cur were investigated by immunohistochemistry,reverse transcription-quantitative polymerase chain reaction(PCR),methylation-specific PCR,western blot,transwell migration assay and proliferation assay.Results showed that 30 lM HA-Cur significantly attenuated the fibrotic functions of myofibroblast in joint contracture in vitro by regulating the methylation of prostaglandin E receptor 2(PTGER2)and inhibiting TGF-b signaling.This may provide a mechanism for the treatment of joint contracture,and provide a molecular target PTGER2 for therapy during the pathogenesis of joint contracture. | Dongjie Yu Ze Zhuang Jianhua Ren Xuefeng Hu Zhe Wang Jieyu Zhang Yuansen Luo Kun Wang Ronghan He Yunbing Wang | 2019 | Regenerative Biomaterials2019，6，5： | 1 |

| 11 | Anti-fungal properties of Puroindoline A against Aspergillus glaucus显示文摘Aspergillus glaucus can grow in low moisture grain,and is one of the main fungi responsible for agricultural product losses.Puroindoline A(PINA)is a tryptophan-rich alkaline adiponectin that can effectively inhibit numerous plant bacteria and fungi.However,the mechanism of PINA against A.glaucus remains unclear.Herein,we found that recombinant PINA(rPINA)could inhibit A.glaucus mycelia growth on salt Czapek dox agar(SCDA)medium and spore germination on Czapek dox(CD)medium.Scanning electron microscopy revealed that incomplete morphological characteristics of both A.glaucus spores and mycelia occurred following rPINA treatment.Laser scanning confocal microscopy(LSCM)showed that rPINA could enter the interior of spores.Flow cytometry and propidium iodide(PI)staining illustrated membranes of spores were severely damaged,especially after treatment with 0.9 mg/mL rPINA for 12 h,and spores with intact membranes were reduced by 30.7%.Additionally,rPINA reduced the mitochondrial membrane potential(MMP)by 5,5′,6,6′-tetrachlorr-1,1′,3,3′-tetraethyl-imidacarbocyanine iodide(JC-1)staining,and caused DNA damage by 4′,6-diamidino-2-phenylindole(DAPI)staining.These results indicated that rPINA may damage cell membranes and DNA structure and reduceMMP,thereby inhibiting the growth of A.glaucus.The antifungal mechanism has been demonstrated in this study,and results show that rPINA has application potential in preventing postharvest loss in the agricultural industry. | Wenjing Yuan Pingping Tian Ang Lyu Yangyong Lyu Wei Zhang Shan Wei Yuansen Hu | 2020 | Grain & Oil Science and Technology2020，3，1： | 0 |
| 12 | Effects of hexanal fumigation on fungal spoilage and grain quality of stored wheat显示文摘The prevention of fungal spoilage is an essential consideration in wheat storage.Recent studies have revealed that volatile organic compounds(VOCs),possibly with natural fungicidal properties,could be produced from stored wheat grains.In this study,the antifungal effect of hexanal,a main component of VOCs from stored wheat,against spoilage fungi on agar plate and in high-moisture wheat grains were investigated via the gas fumigation method.And the impact of hexanal fumigation on grain quality was evaluated through analysis of the malondialdehyde content,fatty acid values,germination percentages and vigor of 16%and 18%moisture wheat grains fumigated with 1.66,2.49,and 3.31 mmol/L hexanal vapor.The results of in vitro antifungal experiments on agar plates revealed that the minimum inhibitory concentration and minimum fungicidal(fatal)concentration of hexanal against the five fungi were 4–14 folds and 4–7 folds lower than those of propionic acid,respectively.The fungal spoilage of high-moisture wheat grains inoculated with pure fungal spores and with naturally occurring fungi could be completely inhibited by 1.66 mmol/L hexanal vapor.During 5-week storage of high-moisture wheat grains fumigated with 1.66,2.49,and 3.31 mmol/L hexanal vapor,the malondialdehyde content in high-moisture wheat grains did not change significantly in all samples,and fatty acid values were slightly higher in 18%moisture wheat than in 16%moisture wheat.The germination percentages and vigor of wheat samples decreased with increased hexanal vapor concentrations and moisture content.These results indicated that hexanal fumigation could be used as an alternative chemical control method to prevent the fungal spoilage of postharvest wheat. | Shuaibing Zhang Minghui Zheng Huanchen Zhai Ping'an Ma Yangyong Lyu Yuansen Hu Jingping Cai | 2021 | Grain & Oil Science and Technology2021，4，1： | 0 |
| 13 | Study on the green extraction of corncob xylan by deep eutectic solvent显示文摘Corn as one of the world's major food crops,its by-product corn cob is also rich in resources.However,the unreasonable utilization of corn cob often causes the environmental pollution,waste of resources and other problems.As one of the most abundant polymers in nature,xylan is widely used in food,medicine,materials and other fields.Corn cob is rich in xylan,which is an ideal raw material for extracting xylan.However,the intractable lignin is covalently linked to xylan,which increases the difficulty of xylan extraction.It has been reported that the deep eutectic solvent(DES)could preferentially dissolve lignin in biomass,thereby dissolving the xylan.Then,the xylan in the extract was separated by ethanol precipitation method.The xylan precipitate was obtained after centrifugation,while the supernatant was retained.The components of the supernatant after ethanol precipitation were separated by the rotary evaporator.The ethanol,water and DES were collected for the subsequent extraction of corn cob xylan.In this study,a novel way was provided for the green production of corn cob xylan.The DES was used to extract xylan from corn cob which was used as the raw material.The effects of solid-liquid ratio,reaction time,reaction temperature and water content of DES on the extraction rate of corn cob xylan were investigated by the single factor test.Furthermore,the orthogonal test was designed to optimize the xylan extraction process.The structure of corn cob xylan was analyzed and verified.The results showed that the optimum extraction conditions of corn cob xylan were as follows:the ratio of corn cob to DES was 1:15(g:mL),the extraction time was 3 h,the extraction temperature was 60℃,and the water content of DES was 70%.Under these conditions,the extraction rate of xylan was 16.46%.The extracted corn cob xylan was distinctive triple helix of polysaccharide,which was similar to the structure of commercially available xylan.Xylan was effectively and workably extracted from corn cob by the DES method.This study provided a new approach for high value conversion of corn cob and the clean production of xylan. | Bingyu Jiao Le Wang Haitao Gui Zifu Ni Rong Du Yuansen Hu | 2024 | Grain & Oil Science and Technology2024，7，1： | 0 |
