| 1 | Identification of Hercynian shoshonitic intrusive rocks in central Hainan Island and its geotectonic implications显示文摘An identification has been made of some shoshonitic intrusive rocks in central Hainan Island recently. These rocks are K-rich (K2O=2.9%―5.1%, K2O/Na2O=0.95―2.12), distinctly enriched in LILE and LREE, strongly depleted in Nb, Ta, and moder- ately depleted in Sr and Ti, with (87Sr/86Sr)i = 0.70859―0.71425 and ε Nd(t) = (?2.77―?7.49). They were derived from an EMⅡ-type mantle source. The enrichment process is related to metasomatism of depleted mantle caused by a great amount of fluid-melt released from oceanic crust and terri- genous sediments at great depth (eclogite facies) during the subduction of the South China plate under the Indochina-South China Sea plate in the Carbon- iferous–Early Permian. A SHRIMP U-Pb zircon dating yields a crystallization age of 272±7 Ma for the sho- shonitic intrusions, which is coeval with the strongly peraluminous granites found in central Hainan Island. These two kinds of rocks generally possess syn-intrusion ductile deformation structures. Thus they are considered to have been generated during the early stage (syn-thrust phase) of a post-collisional event. The primary magma of shoshonitic rocks was produced at a depth > 80 km by decompression- dehydration melting of previously enriched litho- spheric mantle wedge, phlogopite-bearing garnet peridotite, which was in turn caused by the break-off of a descendent slab and upwelling of a hot as- thenosphere. The rising of melts was accompaniedby crustal contamination and crystallization fractiona- tion (AFC). Combining with other related data, it is proposed that the southwards subduction and amal- gamation of the South China plate with the Indo- China-South China Sea plate took place at ca. 287- 278 Ma, which was a part of the convergence proc- ess of the Pangea supercontinent. The suture zone was probably located along the line of Song Ma-Beibu Gulf-north margin of the Yunkai Moun- tains-Wuyi Mountains. | XIE Caifu ZHU Jinchu DING Shijiang ZHANG Yeming FU Tai'an LI Zhihong | 2006 | Chinese Science Bulletin2006，51，20： | 17 |
| 2 | One-step synthesis and electromagnetic absorption properties of high entropy rare earth hexaborides(HE REB6)and high entropy rare earth hexaborides/borates(HE REB6/HE REB03)composite powders显示文摘Considering the emergence of severe electromagnetic interference problems,it is vital to develop electromagnetic(EM)wave absorbing materials with high dielectric,magnetic loss and optimized impedance matching.However,realizing the synergistic dielectric and magnetic losses in a single phase material is still a challenge.Herein,high entropy(HE)rare earth hexaborides(REB6)powders with coupling of dielectric and magnetic losses were designed and successfully synthesized through a facial one-step boron carbide reduction method,and the effects of high entropy borates intermedia phases on the EM wave absorption properties were investigated.Five HE REB6 ceramics including(Ce0.2Y0.2Sm0.2Er0.2Yb0.2)B6,(Ce0.2Hu0.2Sm0.2Er0.2Yb0.2)B6,(Ce0.2Y0.2Eu0.2Er0.2Yb0.2)B6,(Ce0.2Ya2Sm0.2Eu0.2Yb0.2)B6,and(Nd0.2Y0.2Sm0.2Eu0.2Yb0.2)B6 possess CsCl-type cubic crystal structure,and their theoretical densities range from 4.84 to 5.25 g/cm^(3).(Ce02Y0.2Sm0.2Er0.2Yb02)B6 powders with the average particle size of 1.86 jim were found to possess the best EM wave absorption properties among these hexaborides.The RLmin value of(Ce0.2Y0.2Sm0.2Er0.2Yb0.2)B6 reaches-33.4 dB at 11.5 GHz at thickness of 2 mm;meanwhile,the optimized effective absorption bandwidth(EAB)is 3.9 GHz from 13.6 to 17.5 GHz with a thickness of 1.5 mm.The introduction of HE REB03(RE=Ce,Y,Sm,Eu,Er,Yb)as intermediate phase will give rise to the mismatching impedance,which will further lead to the reduction of reflection loss.Intriguingly,the HEREB6/HEREB03 still possess wide effective absorption bandwidth of 4.1 GHz with the relative low thickness of 1.7 mm.Considering the better stability,low density,and good EM wave absorption properties,HE REB6 ceramics are promising as a new type of EM wave absorbing materials. | Weiming ZHANG Biao ZHAO Huimin XIANG Fu-Zhi DAI Shijiang WU Yanchun ZHOU | 2021 | Journal of Advanced Ceramics2021，10，1： | 15 |
| 3 | Metamorphosed mafic rocks with N-type MORE geochemical features in Hainan Island-Remnants of the Paleo-Tethys Oceanic Crust?显示文摘A number of metamorphosed mafic rocks occurred within the Paleozoic strata in the Chenxing and Bangxi regions at the northern side of the Changjiang-Qionghai Fault in Central Hainan Island. These metamorphosed mafic rocks are tholeiites in chemistry. They are characterized by extreme depletion of Th, Nb, Ta and LREEs, resembling the depleted N-type mid-ocean ridge basalts (MORE). Field relations suggest that the protolith of the metamorphosed mafic rocks were likely formed in Paleozoic. These metamorphosed mafic rocks with N-type MORB geochemical features were probably the remnants of the Paleo-Tethys oceanic crust. | LI Xianhua, ZHOU Hanwen, DING Shijiang, LEE Chi-yu, ZHANG Renjie, ZHANG Yeming & GE Wenchun1.

| 4 | High entropy rare earth hexaborides/tetraborides(HE REB_(6)/HE REB_(4)) composite powders with enhanced electromagnetic wave absorption performance显示文摘The increasing electromagnetic hazards including electromagnetic interference and electromagnetic pollution,which were stemmed from massive usage of electromagnetic technology,have triggered widespread concerns.To cope with this challenge,electromagnetic wave absorbing materials with high performance are greatly needed.Composite construction has been widely applied in electromagnetic(EM)wave absorbing materials to achieve high permittivity,high permeability and impedance matching.However,high-temperature stability,oxidation and corrosion resistance are still unignorable issues.Herein,high entropy hexaborides/tetraborides(HE REB_(6)/HE REB_(4))composites with synergistic dielectric and magnetic losses were designed and successfully synthesized through a one-step boron carbide reduction method.The five as-prepared(Y_(0.2) Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2))B_(6)/(Y_(0.2) Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2))B_(4),(Y_(0.2) Nd_(0.2) Sm_(0.2) Er_(0.2) Yb_(0.2))B_(6)/(Y_(0.2) Nd_(0.2) Sm_(0.2) Er_(0.2) Yb_(0.2))B_(4),(Y_(0.2) Nd_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(6)/(Y_(0.2) Nd_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(4),(Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(6)/(Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(4) and(Y_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(6)/(Y_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2) Yb_(0.2))B_(4) contain two phases of HE REB_(6) and HE REB_(4).Among them(Y_(0.2) Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2))B_(6)/(Y_(0.2) Nd_(0.2) Sm_(0.2) Eu_(0.2) Er_(0.2))B_(4)(HE REB_(6)/HE REB_(4)-1)and(Y_(0.2) Nd_(0.2) Sm_(0.2) Er_(0.2) Yb_(0.2))B_(6)/(Y_(0.2) Nd_(0.2) Sm_(0.2) Er_(0.2) Yb_(0.2))B_(4)(HE REB_(6)/HE REB_(4)-2)exhibit excellent EM wave absorption properties.The optimal minimum reflection loss(RL_(m in))and effective absorption bandwidth(E_(AB))of HE REB_(6)/HE REB_(4)-1 and HE REB_(6)/HE REB_(4)-2 are–53.3 dB(at 1.7 mm),4.2 GHz(at 1.5 mm)and–43.5 dB(1.3 mm),4.2 GHz(1.5 mm),respectively.The combination of conducting HE REB_(4) with magnetism into HE REB_(6) as a second phase enhances dielectric and magnetic losses,which lead to enhanced EM wave absorption performance.Considering superior high-temperature stability,oxidation and corrosion resistance of HE REB_(6) and HE REB_(4),HE REB_(6)/HE REB_(4) composite ceramics are promising as a new type of high-performance EM wave absorbing materials. | Weiming Zhang Biao Zhao Na Ni Huimin Xiang Fu-Zhi Dai Shijiang Wu Yanchun Zhou | 2021 | Journal of Materials Science & Technology2021，，28： | 9 |
| 5 | The Glutamatergic Postrhinal Cortex–Ventrolateral Orbitofrontal Cortex Pathway Regulates Spatial Memory Retrieval显示文摘A deficit in spatial memory has been taken as an early predictor of Alzheimer’s disease(AD) or mild cognitive impairment(MCI). The uncinate fasciculus(UF) is a long-range white-matter tract that connects the anterior temporal lobe with the orbitofrontal cortex(OFC)in primates. Previous studies have shown that the UF impairment associated with spatial memory deficits may be an important pathological change in aging and AD, but its exact role in spatial memory is not well understood. The pathway arising from the postrhinal cortex(POR) and projecting to the ventrolateral orbitofrontal cortex(vlOFC)performs most of the functions of the UF in rodents.Although the literature suggests an association between spatial memory and the regions connected by the POR–vlOFC pathway, the function of the pathway in spatialmemory is relatively unknown. To further illuminate the function of the UF in spatial memory, we dissected the POR–vlOFC pathway in mice. We determined that the POR–vlOFC pathway is a glutamatergic structure, and that glutamatergic neurons in the POR regulate spatial memory retrieval. We also demonstrated that the POR–vlOFC pathway specifically transmits spatial information to participate in memory retrieval. These findings provide a deeper understanding of UF function and dysfunction related to disorders of memory, as in MCI and AD. | Xinyang Qi Zhanhong Jeff Du Lin Zhu Xuemei Liu Hua Xu Zheng Zhou Cheng Zhong Shijiang Li Liping Wang Zhijun Zhang | 2019 | Neuroscience Bulletin2019，35，3： | 7 |
| 6 | Diagnosis and surgical treatment of intraveneous leiomyomatosis extending into the heart:two cases report and review of the literature显示文摘Objective:To investigate the clinical characteristics,diagnosis and surgical treatment of intravenous leiomyomatosis(IVL),and outline the differences between Chinese and overseas cases.Methods:Clinical data of two IVL cases,treated in our hospital,were analyzed retrospectively and the related literature was also reviewed.The data of preoperative diagnostic rate,surgical procedures,and postoperative recurrence between patients in China and other countries were compared.Results:The first stage operation was performed successfully in 2 patients.However,they refused subsequent therapies,including a second stage operation to excise the remnants of the tumor,uterus,bilateral oviducts and ovaries,and anti-estrogen therapy.Both suffered from IVL recurrence,one at 6-month and the other at 9-month,and died at 16-month and 12-month respectively after the first stage surgery.Worldwide reports of 110 IVL cases were reviewed,which included 28 cases in China and 82 cases in other countries.In the majority of the Chinese patients,tumors only extended into the right atrium rather than the right ventricle(RA 22 cases vs RV 4 cases).However,among the overseas patients,the rate of extension into the right atrium was similar to that of extension into the right ventricle(RA 41 cases vs RV 38 cases).The rate of hysterectomies was not significantly different between Chinese and overseas patients(67.86% vs 55.9%,P=0.278).The rate of correct preoperative diagnosis in the Chinese patients was significantly lower than that in the overseas patients(32.14% vs 80%,P=0.000002),as well as the rate of complete excision of the tumor(22.7% vs 75.5%,P=0.000001).The proportion of patients who undergoing a single-stage or a two-stage operation was similar in Chinese and overseas patients.The recurrence rate was significantly higher in the Chinese patients than in the overseas patients(36.8% vs 9.1%,P=0.0055),and the patients with tumor recurrence were partial tumor excision patients.Conclusion:The possibility of IVL should be considered if echocardiography in female patients demonstrates a tumor in the right heart and a mass in the inferior vena cava(IVC).Further imaging should be performed to confirm the diagnosis.The correct diagnosis and accurate preoperative delineation of tumor extension are essential for an optimal surgical outcome.The key point in IVL treatment is the complete excision of tumors(single-stage or two-stage surgical procedure). | Xiaowei Wang Lin Zhang Yijiang Chen Shijiang Zhang Jianwei Qin Yanhu Wu Jinhua Luo | 2009 | Journal of Nanjing Medical University2009，23，5： | 5 |
| 7 | Achieving ultra-broadband electromagnetic wave absorption in high-entropy transition metal carbides (HE TMCs)显示文摘Electronic devices pervade everyday life,which has triggered severe electromagnetic(EM)wave pollution.To face this challenge,developing EM wave absorbers with ultra-broadband absorption capacity is critically required.Currently,nano-composite construction has been widely utilized to realize impedance match and broadband absorption.However,complex experimental procedures,limited thermal stability,and interior oxidation resistance are still unneglectable issues.Therefore,it is appealing to realize ultra-broadband EM wave absorption in single-phase materials with good stability.Aiming at this target,two high-entropy transition metal carbides(HE TMCs)including(Zr,Hf,Nb,Ta)C(HE TMC-2)and(Cr,Zr,Hf,Nb,Ta)C(HE TMC-3)are designed and synthesized,of which the microwave absorption performance is investigated in comparison with previously reported(Ti,Zr,Hf,Nb,Ta)C(HE TMC-1).Due to the synergistic effects of dielectric and magnetic losses,HE TMC-2 and HE TMC-3 exhibit better impedance match and wider effective absorption bandwidth(EAB).In specific,the exclusion of Ti element in HE TMC-2 endows it optimal minimum reflection loss(RL_(min))and EAB of−41.7 dB(2.11 mm,10.52 GHz)and 3.5 GHz(at 3.0 mm),respectively.Remarkably,the incorporation of Cr element in HE TMC-3 significantly improves the impedance match,thus realizing EAB of 10.5,9.2,and 13.9 GHz at 2,3,and 4 mm,respectively.The significance of this study lays on realizing ultra-broadband capacity in HE TMC-3(Cr,Zr,Hf,Nb,Ta),demonstrating the effectiveness of high-entropy component design in tailoring the impedance match. | Weiming ZHANG Huimin XIANG Fu-Zhi DAI Biao ZHAO Shijiang WU Yanchun ZHOU | 2022 | Journal of Advanced Ceramics2022，11，4： | 5 |
| 8 | Can multi-modal neuroimaging evidence from hippocampus provide biomarkers for the progression of amnestic mild cognitive impairment?显示文摘Impaired structure and function of the hippocampus is a valuable predictor of progression from amnestic mild cognitive impairment(a MCI) to Alzheimer's disease(AD). As a part of the medial temporal lobe memory system,the hippocampus is one of the brain regions affected earliest by AD neuropathology,and shows progressive degeneration as a MCI progresses to AD. Currently,no validated biomarkers can precisely predict the conversion from a MCI to AD. Therefore,there is a great need of sensitive tools for the early detection of AD progression. In this review,we summarize the specifi c structural and functional changes in the hippocampus from recent a MCI studies using neurophysiological and neuroimaging data. We suggest that a combination of advanced multi-modal neuroimaging measures in discovering biomarkers will provide more precise and sensitive measures of hippocampal changes than using only one of them. These will potentially affect early diagnosis and disease-modifying treatments. We propose a new sequential and progressive framework in which the impairment spreads from the integrity of fibers to volume and then to function in hippocampal subregions. Meanwhile,this is likely to be accompanied by progressive impairment of behavioral and neuropsychological performance in the progression of a MCI to AD. | Jiu Chen Zhijun Zhang Shijiang Li | 2015 | Neuroscience Bulletin2015，31，1： | 4 |
| 9 | Enabling highly efficient and broadband electromagnetic wave absorption by tuning impedance match in high-entropy transition metal diborides (HETMB_(2))显示文摘The advance in communication technology has triggered worldwide concern on electromagnetic wave pollution.To cope with this challenge,exploring high-performance electromagnetic(EM)wave absorbing materials with dielectric and magnetic losses coupling is urgently required.Of the EM wave absorbers,transition metal diborides(TMB2)possess excellent dielectric loss capability.However,akin to other single dielectric materials,poor impedance match leads to inferior performance.High-entropy engineering is expected to be effective in tailoring the balance between dielectric and magnetic losses through compositional design.Herein,three HE TMB2 powders with nominal equimolar TM including HE TMB2-I(TM=Zr,Hf,Nb,Ta),HE TMB2-2(TM=Ti,Zr,Hf,Nb,Ta),and HE TMB2-3(TM=Cr,Zr,Hf,Nb,Ta)have been designed and prepared by one-step boro/carbothermal reduction.As a result of synergistic effects of strong attenuation capability and impedance match,HE TMB2-1 shows much improved performance with the optimal minimum reflection loss(RL_(min))of-59.6 dB(8.48 GHz,2.68 mm)and effective absorption bandwidth(EAB)of 7.6 GHz(2.3 mm).Most impressively,incorporating Cr in HE TMB2-3 greatly improves the impedance match over 1-18 GHz,thus achieving the RLmin of-56.2 dB(8.48 GHz,2.63 mm)and the EAB of 11.0 GHz(2.2 mm),which is superior to most other EM wave absorbing materials.This work reveals that constructing high-entropy compounds,especially by incorporating magnetic elements,is effectual in tailoring the impedance match for highly conductive compounds,i.e.,tuning electrical conductivity and boosting magnetic loss to realize highly efficient and broadband EM wave absorption with dielectric and magnetic coupling in single-phase materials. | Weiming ZHANG Fu-Zhi DAI Huimin XIANG Biao ZHAO Xiaohui WANG Na NI Rajamallu KARRE Shijiang WU Yanchun ZHOU | 2021 | Journal of Advanced Ceramics2021，10，6： | 4 |
| 10 | Accounting greenhouse gas emissions of food consumption between urban and rural residents in China: a whole production perspective显示文摘Food consumption is necessary for human survival.On a global scale,the greenhouse gas(GHG)emission related to food consumption accounts for 19%–29%of the total GHG emission.China has the largest population in the world,which is experiencing a rapid development.Under the background of urbanization and the adjustment of the diet structure of Chinese residents,it is critical to mitigate the overall GHG emission caused by food consumption.This study aims to employ a single-region input-output(SRIO)model and a multi-regional input-output(MRIO)model to measure GHG emission generated from food consumption in China and compare the contributions of different industrial sectors,uncovering the differences between urban and rural residents and among different provinces(autonomous regions/municipalities),as well as identifying the driving forces of GHG emission from food consumption at a national level.The results indicate that the total GHG emission generated from food consumption in China tripled from 157 Mt CO_(2)e in 2002 to 452 Mt CO_(2)e in 2017.The fastest growing GHG emission is from the consumption of other processed food and meat products.Although GHG emissions from both urban and rural residents increased,the gap between them is increasing.Agriculture,processing and manufacture of food,manufacture of chemical and transportation,storage and post services sectors are key sectors inducing food consumption related GHG emissions.From a regional perspective,the top five emission provinces(autonomous regions/municipalities)include Shandong,Hubei,Guangdong,Zhejiang,and Jiangsu.Based on such results,policy recommendations are proposed to mitigate the overall GHG emission from food consumption. | Yanfeng XU Yong GENG Ziyan GAO Shijiang XIAO Chenyi ZHANG Mufan ZHUANG | 2022 | Frontiers in Energy2022，16，2： | 2 |
| 11 | Impaired Parahippocampal Gyrus-Orbitofrontal Cortex Circuit Associated with Visuospatial Memory Deficit as a Potential Biomarker and Interventional Approach for Alzheimer Disease显示文摘The parahippocampal gyrus-orbitofrontal cortex(PHG-OFC)circuit in humans is homologous to the postrhinal cortex(POR)-ventral lateral orbitofrontal cortex(vlOFC)circuit in rodents.Both are associated with visuospatial malfunctions in Alzheimer’s disease(AD).However,the underlying mechanisms remain to be elucidated.In this study,we explored the relationship between an impaired POR-vlOFC circuit and visuospatial memory deficits through retrograde tracing and in vivo local field potential recordings in 5XFAD mice,and investigated alterations of the PHG-OFC circuit by multi-domain magnetic resonance imaging(MRI)in patients on the AD spectrum.We demonstrated that an impaired glutamatergic POR-vlOFC circuit resulted in deficient visuospatial memory in 5XFAD mice.Moreover,MRI measurements of the PHG-OFC circuit had an accuracy of 77.33%for the classification of amnestic mild cognitive impairment converters versus non-converters.Thus,the PHG-OFC circuit explains the neuroanatomical basis of visuospatial memory deficits in AD,thereby providing a potential predictor for AD progression and a promising interventional approach for AD. | Lin Zhu Zan Wang Zhanhong Du Xinyang Qi Hao Shu Duan Liu Fan Su Qing Ye Xuemei Liu Zheng Zhou Yongqiang Tang Ru Song Xiaobin Wang Li Lin Shijiang Li Ying Han Liping Wang Zhijun Zhang | 2020 | Neuroscience Bulletin2020，36，8： | 2 |

| 14 | Effect of Impregnation Sequence on Propane Dehydrogenation Performance of PtSnNa/ZSM-5 Catalyst显示文摘The effects of the sequence for impregnation of metal precursors on the performance of PtSnNa/ZSM-5 catalyst for propane dehydrogenation to propene were studied in this paper.Some methods such as XRD,TPDA,BET,H2-TPR,XPS,ICP,TEM and hydrogen chemisorption were used to characterize the catalysts.The structure of ZSM-5 zeolite was not destroyed by the introduction of metal components.Meanwhile the different impregnation sequence of metal precursors could affect the behavior of Sn4+species entering the ZSM-5 channel,and the interaction between platinum and tin species,as well as the degree for reduction of Pt and Sn components.As a result,the prepared catalysts exhibited different reaction activity and selectivity.Compared with the co-impregnation treated catalyst,the catalysts prepared by the sequential impregnation method showed better catalytic activity in propane dehydrogenation,especially the one prepared through impregnation with tin precursor at first.Finally,a model for the effect of impregnation sequence on the distribution of Pt and Sn species in PtSnNa/ZSM-5 catalyst was proposed. | Liu Hui Zhou Yuming Zhang Yiwei Sheng Xiaoli Zhang Zewu Zhou Shijiang | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，4： | 1 |
| 15 | The effect of internal tides on the vertical structure of tidal current in the North Huanghai Sea显示文摘The tidal current is generally predominant in China’s offshore areas. The vertical structure of the observedtidal current is quite complicated with the presence of seasonal thermocline. The observed tidal current may be divided into two parts, an averaged barotropic tide current and a variation tide current. A method for studying the vertical structure of tidal current is developed from the constitution and distribution of energy, and the vertical structure of the observed tide current in the North Huanghai Sea is studied on the basis of the method. The result shows that the reason why the energy of the tidal current is concentrated on the neighbourhood of the thermocline mainly lies in the internal tides i under certain conditions, the fact that the direction of the internal tide current above the thermocline is opposite to the one below the thermocline will be able to cause the rotary directions of the observed tidal current above and below the thermocline to be in opposite.

| 16 | AcbHLH144 transcription factor negatively regulates phenolic biosynthesis to modulate pineapple internal browning显示文摘Internal browning(IB),a major physiological disorder of pineapples,usually happens in postharvest processes,but the underlying mechanism remains elusive.The bHLH transcription factors are involved in regulating various biological processes,but whether they could regulate tissue browning in fruit during storage remains unknown.Here we showed that the phenolic biosynthesis pathway was activated in pineapples showing IB following 9 days of storage.AcbHLH144 expression was the highest of the 180 transcription factors identified,downregulated in pineapple with IB,and negatively correlated with the major phenolic biosynthetic genes.AcbHLH144 was shown to be localized in the nucleus and its transient overexpression in pineapples and overexpression in Arabidopsis decreased phenolic biosynthesis.The yeast one-hybrid assay and electrophoretic mobility shift assay showed that AcbHLH144 directly bound to the Ac4CL5 promoter and the dual-luciferase reporter assay showed that it inactivated Ac4CL5 transcription.These results strongly suggest AcbHLH144 as a repressor for phenolic biosynthesis.Abscisic acid(ABA)alleviated IB,reduced phenolic accumulation,and downregulated phenolic biosynthetic genes,including Ac4CL5.Transcriptomic analysis showed that AcbHLH144 was the most upregulated of all 39 bHLHs in response to ABA.ABA enhanced AcbHLH144 expression,reduced phenolic contents,and downregulated phenolic biosynthetic genes in pineapples transiently overexpressing AcbHLH144.Moreover,ABA enhanced enzyme activity of GUS driven by the AcbHLH144 promoter.These results showed that AcbHLH144 as a repressor for phenolic biosynthesis could be activated by ABA.Collectively,the work demonstrated that AcbHLH144 negatively regulated phenolic biosynthesis via inactivating Ac4CL5 transcription to modulate pineapple IB.The findings provide novel insight into the role of AcbHLH144 in modulating pineapple IB during postharvest processes. | Qian Li Guang Wang Ling Zhang Shijiang Zhu | 2023 | Horticulture Research2023，10，10： | 0 |
| 17 | Current-Induced Magnetic Switching in an L1_(0) FePt Single Layer with Large Perpendicular Anisotropy Through Spin–Orbit Torque显示文摘In this study,current-induced partial magnetization-based switching was realized through the spin–orbit torque(SOT)in single-layer L1_(0) FePt with a perpendicular anisotropy(K_(u⊥))of 1.19×10^(7) erg·cm^(-3)(1 erg·cm^(-3)=0.1 J·m^(-3)),and its corresponding SOT efficiency(βDL)was 8×10^(-6) Oe·(A·cm^(-2))^(-1)(1 Oe=79.57747 A·m^(-1)),which is several times higher than that of the traditional Ta/CoFeB/MgO structure reported in past work.The SOT in the FePt films originated from the structural inversion asymmetry in the FePt films since the dislocations and defects were inhomogeneously distributed within the samples.Furthermore,the FePt grown on MgO with a granular structure had a larger effective SOT field and effi-ciency than that grown on SrTiO_(3)(STO)with a continuous structure.The SOT efficiency was found to be considerably dependent on not only the sputtering temperature-induced chemical ordering but also the lattice mismatch-induced evolution of the microstructure.Our findings can provide a useful means of efficiently electrically controlling a magnetic bit that is highly thermally stable via SOT. | Kaifeng Dong Chao Sun Laizhe Zhu Yiyi Jiao Ying Tao Xin Hu Ruofan Li Shuai Zhang Zhe Guo Shijiang Luo Xiaofei Yang Shaoping Li Long You | 2022 | Engineering2022，8，5： | 0 |
| 18 | Biomechanical characterization of a novel ring connector for sutureless aortic anastomosis显示文摘The surgical treatment for aortic diseases remains a challenge for any cardiac surgeon. The use of sutureless ring connector in aortic anastomosis can simplify the procedure and shorten anastomosis time. Therefore, we developed a novel device for sutureless aortic anastomosis. A series of experiments were carried out for tensile and leakproofcapacity assessments to verify the feasibility of the ring connector by using fresh swine aorta samples. In in vivo test,the ring connector was implanted in 6 swine with follow-up of 6 months. Radiographic and pathological studies of the aorta were performed. In the tensile tests, the strength was 32.7±5.9 Newton(N) in the sutureless anastomosis group,compared with 73.3±12.5 N in the control group by traditional manual suture. In the leakproof-capacity assessment,no sign of either leakage or bursting was evident at 280 mmHg of internal pressure in the aorta samples. In in vivo tests,it took 9.47±0.3 minutes for the sutureless anastomosis, compared with 15.58± 1.39 minutes for hand-sewn suturing. Insertion was easy and rapid. Radiographic and pathological studies were performed at first month, third month and sixth month after surgery, each time obtained from the two swine, showed patency of the anastomosis and no signs of stenosis, blood leakage, migration or pseudoaneurysm formation, except one paralyzed swine developed of thrombo-occlusion at the site of the sutureless anastomosis.

| 19 | Preliminary feasibility and hemodynamic performance of a newlydeveloped self-expanding bioprosthesis and 16-F delivery system in transcatheter aortic valve implantation in sheep显示文摘We sought to evaluate the feasibility and hemodynamic performance of a new self-expanding bioprosthesis and 16-F delivery system in sheep.A 23-mm new self-expanding aortic bioprosthesis was implanted in sheep(n = 10) with a 16-F catheter via the right common carotid artery.Each sheep underwent angiography and coronary angiography before intervention,immediately and 1 h after stent implantation.Electrocardiographic monitoring was carried out during and 2 h after the procedure.Transthoracic echocardiography was employed to detect hemodynamic performance before intervention,immediately and 1 and 2 h after stent implantation.All sheep were euthanized 2 h after successful implantation for macroscopic inspection.In all cases,the new self-expanding aortic bioprosthesis was successfully delivered to the aortic root and released with a 16-F catheter.Successful implantation was achieved in 8 of 10 sheep.Hemodynamic performance and device position of successful implantation were stable 2 h after device deployment.Atrioventricular block was not observed.We conclude that it is feasible to implant the new self-expanding aortic valve with a 16-F delivery system into sheep hearts via the retrograde route. | Jing Cai Yanhui Sheng Shijiang Zhang Wei Sun Rong Yang Liping Miao Xiangqing Kong | 2012 | The Journal of Biomedical Research2012，26，3： | 0 |
| 20 | Theoretical predictions and experimental verification on the phase stability of enthalpy-stabilized HE TMREB_(2)s显示文摘Transition metal diborides(TMB_(2)s)are the materials of choice in extreme environments due to their excellent thermal and chemical stabilities.However,the degradation of oxidation resistance of TMB_(2)s at elevated temperature still hinders their applications.To cope with this challenge,it is effective to incorporate rare earth elements to form high-entropy transition and rare-earth metal diborides(HE TMREBs).To obtain thermodynamically stable single-phase structures for HE TMREB_(2)s,a“16×16 mixed enthalpy matrix”is constructed using first-principles calculations to predict the single-phase formation ability of120 two-component diborides(TCBs).Through the use of the“16×16 mixed enthalpy matrix”of TCBs,specific combinations of TMB_(2)s and REB_(2)s that are most likely to form single-phase HE TMREB_(2)s are confirmed.Subsequently,based on the energy distribution of the local mixing enthalpies of all possible configurations,the enthalpy and entropy descriptors of HE TMREB_(2)s(RE=Sc,Lu,Tm,Er,Ho and Dy)are investigated.It is found that the mixing enthalpy plays a critical role in the stability of the single-phase HE TMREB_(2)s,i.e.,HE TMREB_(2)s are enthalpy-stabilized materials.The experimental results further confirm that enthalpy dominates the thermodynamic domain and drives the stability of REB_(2)s in HE TMREB_(2)s.This study validates that enthalpy-stabilized HE TMREB_(2)s can further expand the compositional space of ultrahigh temperature ceramics(UHTCs)and is expected to further improve the oxidation resistance and high temperature properties of UHTCs. | Ze Zhang Shizhen Zhu Fu-Zhi Dai Huimin Xiang Yanbo Liu Ling Liu Zhuang Ma Shijiang Wu Fei Liu Kuang Sun Yanchun Zhou | 2022 | Journal of Materials Science & Technology2022，，26： | 0 |
