| 1 | Targeting PI3K/AKT signaling for treatment of idiopathic pulmonary fibrosis显示文摘Idiopathic pulmonary fibrosis(IPF) is a chronic progressive fibrotic interstitial pneumonia with unknown causes. The incidence rate increases year by year and the prognosis is poor without cure.Recently, phosphatidylinositol 3-kinase(PI3 K)/protein kinase B(PKB/AKT) signaling pathway can be considered as a master regulator for IPF. The contribution of the PI3 K/AKT in fibrotic processes is increasingly prominent, with PI3 K/AKT inhibitors currently under clinical evaluation in IPF. Therefore,PI3 K/AKT represents a critical signaling node during fibrogenesis with potential implications for the development of novel anti-fibrotic strategies. This review epitomizes the progress that is being made in understanding the complex interpretation of the cause of IPF, and demonstrates that PI3 K/AKT can directly participate to the greatest extent in the formation of IPF or cooperate with other pathways to promote the development of fibrosis. We further summarize promising PI3 K/AKT inhibitors with IPF treatment benefits, including inhibitors in clinical trials and pre-clinical studies and natural products, and discuss how these inhibitors mitigate fibrotic progression to explore possible potential agents, which will help to develop effective treatment strategies for IPF in the near future. | Jincheng Wang Kaili Hu Xuanyan Cai Bo Yang Qiaojun He Jiajia Wang Qinjie Weng | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 31 |
| 2 | Three-dimensional chiral microstructures fabricated by structured optical vortices in isotropic material显示文摘Optical vortices,a type of structured beam with helical phase wavefronts and‘doughnut’-shaped intensity distributions,have been used to fabricate chiral structures in metals and spiral patterns in anisotropic polarization-dependent azobenzene polymers.However,in isotropic polymers,the fabricated microstructures are typically confined to non-chiral cylindrical geometry due to the two-dimensional‘doughnut’-shaped intensity profile of the optical vortices.Here we develop a powerful strategy to realize chiral microstructures in isotropic material by coaxial interference of a vortex beam and a plane wave,which produces threedimensional(3D)spiral optical fields.These coaxial interference beams are generated by designing contrivable holograms consisting of an azimuthal phase and an equiphase loaded on a liquid-crystal spatial light modulator.In isotropic polymers,3D chiral microstructures are achieved under illumination using coaxial interference femtosecond laser beams with their chirality controlled by the topological charge.Our further investigation reveals that the spiral lobes and chirality are caused by interfering patterns and helical phase wavefronts,respectively.This technique is simple,stable and easy to perform,and it offers broad applications in optical tweezers,optical communications and fast metamaterial fabrication. | Jincheng Ni Chaowei Wang Chenchu Zhang Yanlei Hu Liang Yang Zhaoxin Lao Bing Xu Jiawen Li Dong Wu Jiaru Chu | 2017 | Light(Science & Applications)2017，6，1： | 28 |
| 3 | RNA-Seq analysis of yak ovary: improving yak gene structure information and mining reproduction-related genes显示文摘RNA-Seq,a high-throughput(HT)sequencing technique,has been used effectively in large-scale transcriptomic studies,and is particularly useful for improving gene structure information and mining of new genes.In this study,RNA-Seq HT technology was employed to analyze the transcriptome of yak ovary.After Illumina-Solexa deep sequencing,26826516 clean reads with a total of 4828772880 bp were obtained from the ovary library.Alignment analysis showed that 16992 yak genes mapped to the yak genome and 3734 of these genes were involved in alternative splicing.Gene structure refinement analysis showed that7340 genes that were annotated in the yak genome could be extended at the 5′or 3′ends based on the alignments been the transcripts and the genome sequence.Novel transcript prediction analysis identified 6321 new transcripts with lengths ranging from 180 to 14884 bp,and 2267 of them were predicted to code proteins.BLAST analysis of the new transcripts showed that1200?4933 mapped to the non-redundant(nr),nucleotide(nt)and/or SwissProt sequence databases.Comparative statistical analysis of the new mapped transcripts showed that the majority of them were similar to genes in Bos taurus(41.4%),Bos grunniens mutus(33.0%),Ovis aries(6.3%),Homo sapiens(2.8%),Mus musculus(1.6%)and other species.Functional analysis showed that these expressed genes were involved in various Gene Ontology(GO)categories and Kyoto Encyclopedia of Genes and Genomes pathways.GO analysis of the new transcripts found that the largest proportion of them was associated with reproduction.The results of this study will provide a basis for describing the normal transcriptome map of yak ovary and for future studies on yak breeding performance.Moreover,the results confirmed that RNA-Seq HT technology is highly advantageous in improving gene structure information and mining of new genes,as well as in providing valuable data to expand the yak genome information. | LAN DaoLiang XIONG XianRong WEI YanLi XU Tong ZHONG JinCheng ZHI XiangDong WANG Yong LI Jian | 2014 | Science China(Life Sciences)2014，57，9： | 23 |
| 4 | The intrinsic mechanism of corrosion resistance for FCC high entropy alloys显示文摘The concept of high entropy alloys(HEAs) or multi-principal component alloys has inspired a great progress of physical metallurgy along with several unusual phenomena. The high corrosion resistance of HEAs was frequently mentioned but without convincing explanations. In this paper, the intrinsic mechanism of corrosion resistance in FCC HEAs was revealed by designing equal atomic alloys with single solid solution phase. The results showed that the Cr element in FCC HEAs played the dominant role in the corrosion resistance rather than the simple structure from high entropy effect or uniform element distribution. | shang xuliang wang zhijun he feng wang jincheng li junjie yu jiakang | 2018 | Science China(Technological Sciences)2018，61，2： | 11 |
| 5 | Starch grain evidence reveals early pottery function cooking plant foods in North China显示文摘Early pottery sherds excavated in northern China date back to more than 11,000 cal a BP,and are presumed to have been used as cooking vessels.There has been,however,no direct evidence to demonstrate this function.Here we report ancient starch grains recovered from carbonized residues adhering to the bases of flatbottomed vessels excavated from the Zhuannian site dating more than 10,000 cal a BP in the North China Plain.This evidence demonstrates that early pottery was being used to cook cereal grains,particularly millets,and acorns.Because millets were in the process of domestication at thistime,we propose that pottery invention in northern China may have been related to early farming activities. | Xiaoyan Yang Zhikun Ma Tao Wang Linda Perry Quan Li Xiujia Huan Jincheng Yu | 2014 | Chinese Science Bulletin2014，59，32： | 10 |

| 7 | Finite element analysis and optimization of temperature field in GaN-MOCVD reactor显示文摘The electromagnetic field distribution of the in-home GaN-MOCVD reactor heated by induction was simulated by using finite element method (FEM), and the distributions of the magnetic field and the joule heat in the graphite susceptor were obtained. Then the distribution of joule heat was used as the applied load for the simulation of temperature. Based on heat conduction and heat emission models, the temperature distribution in the reactor and the susceptor were gained. In order to improve the uniformity of the temperature on the top surface of the susceptor, the conventional concentric placement of the susceptor in the reactor was changed into the eccentric placement, which effectively improved the temperature uniformity and increased the heat efficiency. | ZHANG JinCheng, LI ZhiMing, HAO Yue , WANG Hao & LI PeiXian Key Laboratory of Fundamental Science for National Defense on Wide Band-Gap Semiconductor Technology, School of Microelectronics, Xidian University, Xi’an 710071, China | 2010 | Science China(Information Sciences)2010，53，10： | 7 |
| 8 | Biomimetic biphasic scaffolds for osteochondral defect repair 5th China-Europe Symposium on Biomaterials in Regenerative Medicine(CESB 2015)Hangzhou,China April 7–10,2015显示文摘The osteochondral defects caused by vigorous trauma or physical disease are difficult to be managed.Tissue engineering provides a possible option to regenerate the damaged osteochondral tissues.For osteochondral reconstruction,one intact scaffold should be considered to support the regeneration of both cartilage and subchondral bone.Therefore,the biphasic scaffolds with the mimic structures of osteochondral tissues have been developed to close this chasm.A variety of biomimetic bilayer scaffolds fabricated from natural or synthetic polymers,or the ones loading with growth factors,cells,or both of them make great progresses in osteochondral defect repair.In this review,the preparation and in vitro and/or in vivo verification of bioinspired biphasic scaffolds are summarized and discussed,as well as the prospect is predicted. | Xuezhou Li Jianxun Ding Jincheng Wang Xiuli Zhuang Xuesi Chen | 2015 | Regenerative Biomaterials2015，2，3： | 7 |
| 9 | Gd-EOB-DTPA-enhanced MRI radiomic features for predicting histological grade of hepatocellular carcinoma显示文摘Background:Prediction models for the histological grade of hepatocellular carcinoma(HCC)remain unsatisfactory.The purpose of this study is to develop preoperative models to predict histological grade of HCC based on gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)-enhanced magnetic resonance imaging(MRI)radiomics.And to compare the performance between artificial neural network(ANN)and logistic regression model.Methods:A total of 122 HCCs were randomly assigned to the training set(n=85)and the test set(n=37).There were 242 radiomic features extracted from volumetric of interest(VOI)of arterial and hepatobiliary phases images.The radiomic features and clinical parameters[gender,age,alpha-fetoprotein(AFP),carcinoembryonic antigen(CEA),carbohydrate antigen 19-9(CA19-9),alanine aminotransferase(ALT),aspartate transaminase(AST)]were selected by permutation test and decision tree.ANN of arterial phase(ANN-AP),logistic regression model of arterial phase(LR-AP),ANN of hepatobiliary phase(ANN-HBP),logistic regression mode of hepatobiliary phase(LR-HBP),ANN of combined arterial and hepatobiliary phases(ANN-AP+HBP),and logistic regression model of combined arterial and hepatobiliary phases(LR-AP+HBP)were built to predict HCC histological grade.Those prediction models were assessed and compared.Results:ANN-AP and LR-AP were composed by AST and radiomic features based on arterial phase.ANN-HBP and LR-HBP were composed by AFP and radiomic features based on hepatobiliary phase.ANN-AP+HBP and LR-AP+HBP were composed by AST and radiomic features based on arterial and hepatobiliary phases.The prediction models could distinguish between high-grade tumors[Edmondson-Steiner(E-S)grade III and IV]and low-grade tumors(E-S grade I and II)in both training set and test set.In the test set,the AUCs of ANN-AP,LR-AP,ANN-HBP,LR-HBP,ANN-AP+HBP and LR-AP+HBP were 0.889,0.777,0.941,0.819,0.944 and 0.792 respectively.The ANN-HBP was significantly superior to LR-HBP(P=0.001).And the ANN-AP+HBP was significantly superior to LR-AP+HBP(P=0.007).Conclusions:Prediction models consisting of clinical parameters and Gd-EOB-DTPA-enhanced MRI radiomic features(based on arterial phase,hepatobiliary phase,and combined arterial and hepatobiliary phases)could distinguish between high-grade HCCs and low-grade HCCs.And the ANN was superior to logistic regression model in predicting histological grade of HCC. | Yingfan Mao Jincheng Wang Yong Zhu Jun Chen Liang Mao Weiwei Kong Yudong Qiu Xiaoyan Wu Yue Guan Jian He | 2022 | Hepatobiliary Surgery and Nutrition2022，11，1： | 6 |

| 11 | Toward emerging gallium oxide semiconductors:A roadmap显示文摘Owing to the advantages of ultra-wide bandgap and rich material systems,gallium oxide(Ga_(2)O_(3))has emerged as a highly viable semiconductor material for new researches.This article mainly focuses on the growth processes,material characteristics,and applications of Ga_(2)O_(3).Compared with single crystals and the epitaxial growth of other wide-bandgap semiconductors,large-size and high-quality��-Ga_(2)O_(3) single crystals can be efficiently grown with a low cost,making them highly competitive.Thanks to the availability of high-quality single crystals,epi-taxial films,and rich material systems,high-performance semiconductor devices based on Ga_(2)O_(3) go through a booming development in recent years.The defects and interfaces of Ga_(2)O_(3) are comprehensively analyzed owing to their significant influence on practical applications.In this study,the two most common applications of Ga_(2)O_(3) materials are introduced.The high breakdown electric field,high working temperature,and excellent Baliga’s figure-of-merit of Ga_(2)O_(3) represent an inspiring prospect for power electronic devices.In addition,the excellent absorption in deep-ultraviolet band provides new ideas for optoelectronic detectors and ensures the dramatic progress.Finally,the summary,challenges,and prospects of the Ga_(2)O_(3) materials and devices are presented and discussed. | Yuan Yuan Weibing Hao Wenxiang Mu Zhengpeng Wang Xuanhu Chen Qi Liu Guangwei Xu Chenlu Wang Hong Zhou Yanni Zou Xiaolong Zhao Zhitai Jia Jiandong Ye Jincheng Zhang Shibing Long Xutang Tao Rong Zhang Yue Hao | 2021 | Fundamental Research2021，1，6： | 5 |
| 12 | The emplacement mechanisms and growth styles of the GuposhanHuashan batholith in western Nanling Range, South China显示文摘The Guposhan-Huashan batholith was emplaced during transition from Tethysian tectonic regime to Pacific tectonic regime in the Middle-Late Jurassic. The regional EW-striking Yishan-Quannan basement deep fault zone, associated with the Tethysian regime, is thought likely to control the formation of the batholith. The development of the batholith was, however, achieved when the Pacific tectonic extensional regime dominated. The batholith consists of seven individual intrusive units that were emplaced subsequently over a 15 m.y. span. Deformation structures and strain analysis of the intrusive units and their country rocks suggest the existence of active and passive emplacement mechanisms. For example, shape-preferred orientation of dioritic enclaves and megacrystic K-spars within earlier units and the development of rim synforms resulted from active mechanisms. It is estimated that active expansion and structural propagation each contributed approximately 27%, and stoping accounted for 46% of the space for the entire batholith. The active emplacement mechanisms produced earlier units at deeper levels of the crust and followed by passive emplacement mechanism at shallower crustal levels when the tectonic regime changed from compression to extension. Each intrusive unit shows a different growth mode. Niumiao and Yangmeishan intrusions show a polarized lateral growth mode, the main-phase Lisong and Wanggao intrusions show either a central growth mode or an eccentric growth mode, and the youngest Baishuidai and Huamei units have a polarized multi-point central growth mode. Both Guposhan and Huashan plutons show a concentric growth zoning pattern with the former built in an outward growth style and the latter an inward growth style. The well-preserved circular shape of both plutons is indicative of relatively stationary magma feeders, suggesting that any considerable horizontal displacement in the region was unlikely even if the area was in an intracontinental strike-slip tectonic setting during the last emplacement phases of the batholith. | FENG ZuoHai WANG ChunZeng LIANG JinCheng LI JunZhao HUANG YongGao LIAO JiaFei WANG Rui | 2011 | Science China Earth Sciences2011，54，1： | 5 |
| 13 | Effect of pickling processes on the microstructure and properties of electroless Ni–P coating on Mg–7.5Li–2Zn–1Y alloy显示文摘The electroless plating Ni–P is prepared on the surface of Mg–7.5Li–2Zn–1Y alloys with different pickling processes.The microstructure and properties of Ni–P coating are investigated.The results show that the Ni–P coatings deposited using the different pickling processes have a different high phosphorus content amorphous Ni–P solid solution structure,and the Ni–P coatings exhibit higher hardness.There is higher phosphorus content of Ni–P amorphous coating using 125 g/L Cr O3and 110 ml/L HNO3(w68%)than using 180 g/L Cr O3and 1 g/L KF during pre-treatment,and the coating structure is more compact,and the Ni–P coatings exhibit more excellent adhesion with substrate(Fcup to22 N).The corrosion potential of Ni–P coating is improved and exhibits good corrosion resistance.As a result,Mg-7.5Li-2Zn-1Y alloy is remarkably protected by the Ni–P coating. | Chunjie Xu Liping Chen Ling Yu Jinxiao Zhang Zhongming Zhang Jincheng Wang | 2014 | Progress in Natural Science:Materials International2014，24，6： | 5 |
| 14 | Precipitation and responding damping behavior of heat-treated AZ31 magnesium alloy显示文摘Microstructure observation and dynamic mechanical analysis were carried out to in- vestigate the precipitation and responding damping behaviors of AZ31 magnesium alloy. All the strain amplitude-dependent damping curves of the aged alloys are located between the curves of solutionized and as-cast alloys, although they have different critical strain amplitudes. The G-L theory is employed to explain the damp- ing mechanism involving the interaction between the dislocation and the precipitated phase. In addition, a damping peak is observed at temperatures close to 330 °C for AZ31 magnesium alloy, which is related to the β-Mg17Al12 phase dissolution. | Diqing WAN Jincheng WANG Gaifang WANG Lin LIN Zhigang FENG Gencang YANG | 2009 | Acta Metallurgica Sinica(English Letters)2009，22，1： | 5 |
| 15 | Stress protein expression in early phase spinal cord ischemia/reperfusion injury显示文摘Spinal cord ischemia/reperfusion injury is a stress injury to the spinal cord. Our previous studies using differential proteomics identified 21 differentially expressed proteins (n > 2) in rabbits with spinal cord ischemia/reperfusion injury. Of these proteins, stress-related proteins included protein disulfide isomerase A3, stress-induced-phosphoprotein 1 and heat shock cognate protein 70. In this study, we established New Zealand rabbit models of spinal cord ischemia/reperfusion injury by abdominal aorta occlusion. Results demonstrated that hind limb function initially improved after spinal cord ischemia/reperfusion injury, but then deteriorated. The pathological morphology of the spinal cord became aggravated, but lessened 24 hours after reperfusion. However, the numbers of motor neurons and interneurons in the spinal cord gradually decreased. The expression of protein disulfide isomerase A3, stress-induced-phosphoprotein 1 and heat shock cognate protein 70 was induced by ischemia/reperfusion injury. The expression of these proteins increased within 12 hours after reperfusion, and then decreased, reached a minimum at 24 hours, but subsequently increased again to similar levels seen at 6-12 hours, showing a characterization of induction-inhibition-induction. These three proteins were expressed only in cytoplasm but not in the nuclei. Moreover, the expression was higher in interneurons than in motor neurons, and the survival rate of interneurons was greater than that of motor neurons. It is assumed that the expression of stress-related proteins exhibited a protective effect on neurons. | Shanyong Zhang Dankai Wu Jincheng Wang Yongming Wang Guoxiang Wang Maoguang Yang Xiaoyu Yang | 2013 | Neural Regeneration Research2013，8，24： | 4 |

| 17 | Microstructural homogeneity and mechanical behavior of a selective laser melted Ti-35Nb alloy produced from an elemental powder mixture显示文摘Although using elemental powder mixtures may provide broad alloy selection at low cost for selective laser melting(SLM), there is still a concern on the resultant microstructural and chemical homogeneity of the produced parts. Hence, this work investigates the microstructure and mechanical properties of a SLM-produced Ti-35 Nb composite(in wt%) using elemental powder. The microstructural characteristics including ? phase, undissolved Nb particles and chemical homogeneity were detailed investigated.Nanoindentation revealed the presence of relatively soft undissolved Nb particles and weak interface bonding around Nb-rich regions in as-SLMed samples. Solid-solution treatment can not only improve chemical homogeneity but also enhance bonding through grain boundary strengthening, resulting in43 % increase in tensile elongation for the heat-treated Ti-35 Nb compared to the as-SLMed counterpart. The analyses of tensile fractures and shear bands further confirmed the correlation between the different phases and the ductility of Ti-35 Nb. In particular, the weak bonding between undissolved Nb and the matrix in the as-SLMed sample reduces its ductility while the ? grains in solid-solution treated Ti-Nb alloy can induce a relatively stable plastic flow therefore better ductility. This work sheds insight into the understanding of homogenization of microstructure and phases of SLM-produced alloys from an elemental powder mixture. | Jincheng Wang Yujing Liu Chirag Dhirajlal Rabadia Shun-Xing Liang Timothy Barry Sercombe Lai-Chang Zhang | 2021 | Journal of Materials Science & Technology2021，，2： | 4 |
| 18 | Assessment of organic compost and biochar in promoting phytoremediation of crude-oil contaminated soil using Calendula officinalis in the Loess Plateau, China显示文摘The Loess Plateau,located in Gansu Province,is an important energy base in China because most of the oil and gas resources are distributed in Gansu Province.In the last 40 a,ecological environment in this region has been extremely destroyed due to the over-exploitation of crude-oil resources.Remediation of crude-oil contaminated soil in this area remains to be a challenging task.In this study,in order to elucidate the effects of organic compost and biochar on phytoremediation of crude-oil contaminated soil(20 g/kg)by Calendula officinalis,we designed five treatments,i.e.,natural attenuation(CK),planted C.officinalis only(P),planted C.officinalis with biochar amendment(PB),planted C.officinalis with organic compost amendment(PC),and planted C.officinalis with co-amendment of biochar and organic compost(PBC).After 152 d of cultivation,total petroleum hydrocarbons(TPH)removal rates of CK,P,PB,PC and PBC were 6.36%,50.08%,39.58%,73.10%and 59.87%,respectively.Shoot and root dry weights of C.officinalis significantly increased by 172.31%and 80.96%under PC and 311.61%and 145.43%under PBC,respectively as compared with P(P<0.05).Total chlorophyll contents in leaves of C.officinalis under P,PC and PBC significantly increased by 77.36%,125.50%and 79.80%,respectively(P<0.05)as compared with PB.Physical-chemical characteristics and enzymatic activity of soil in different treatments were also assessed.The highest total N,total P,available N,available P and SOM(soil organic matter)occurred in PC,followed by PBC(P<0.05).C.officinalis rhizospheric soil dehydrogenase(DHA)and polyphenol oxidase(PPO)activities in PB were lower than those of other treatments(P<0.05).The values of ACE(abundance-based coverage estimators)and Chao 1 indices for rhizospheric bacteria were the highest under PC followed by PBC,P,PB and CK(P<0.05).However,the Shannon index for bacteria was the highest under PC and PBC,followed by P,PB and CK(P<0.05).In terms of soil microbial community composition,Proteiniphilum,Immundisolibacteraceae and Solimonadaceae were relatively more abundant under PC and PBC.Relative abundances of Pseudallescheria,Ochroconis,Fusarium,Sarocladium,Podospora,Apodus,Pyrenochaetopsis and Schizothecium under PC and PBC were higher,while relative abundances of Gliomastix,Aspergillus and Alternaria were lower under PC and PBC.As per the nonmetric multidimensional scaling(NMDS)analysis,application of organic compost significantly promoted soil N and P contents,shoot length,root vitality,chlorophyll ratio,total chlorophyll,abundance and diversity of rhizospheric soil microbial community in C.officinalis.A high p H value and lower soil N and P contents induced by biochar,altered C.officinalis rhizospheric soil microbial community composition,which might have restrained its phytoremediation efficiency.The results suggest that organic compost-assisted C.officinalis phytoremediation for crude-oil contaminated soil was highly effective in the Loess Plateau,China. | WANG Jincheng JING Mingbo ZHANG Wei ZHANG Gaosen ZHANG Binglin LIU Guangxiu CHEN Tuo ZHAO Zhiguang | 2021 | Journal of Arid Land2021，13，6： | 4 |
| 19 | Customized reconstructive prosthesis design based on topological optimization to treat severe proximal tibia defect显示文摘A novel reconstructive prosthesis was designed with topological optimization(TO)and a lattice structure to enhance biomechanical and biological properties in the proximal tibia.The biomechanical performance was validated through finite element analysis(FEA)and biomechanical tests.The tibia with inhomogeneous material properties was reconstructed according to computed tomography images,and different components were designed to simulate the operation.Minimum compliance TO subject to a volume fraction constraint combined with a graded lattice structure was utilized to redesign the prosthesis.FEA was performed to evaluate the mechanical performances of the tibia and implants after optimization,including stress,micromotion,and strain energy.The results were analyzed by paired-samples t tests,and p<0.05 was considered significant.Biomechanical testing was used to verify the tibial stresses.Compared to the original group(OG),the TO group(TOG)exhibited lower stress on the stem,and the maximum von Mises stresses were 87.2 and 53.1 MPa,respectively,a 39.1%reduction(p<0.05).Conversely,the stress and strain energy on the tibia increased in the TOG.The maximum von Mises stress values were 16.4 MPa in the OG and 22.9 MPa in the TOG with a 39.6%increase(p<0.05),and the maximum SED value was 0.026 MPa in the OG and 0.042 MPa in the TOG,corresponding to an increase of 61.5%(p<0.05).The maximum micromotions in the distal end of the stem were 135μm in the OG and 68μm in the TOG,almost a 50%reduction.The stress curves of the biomechanical test coincided well with the FEA results.The TO approach can effectively reduce the whole weight of the prosthesis and improve the biomechanical environment of the tibia.It could also pave the way for next-generation applications in orthopedics surgery. | Aobo Zhang Hao Chen Yang Liu Naichao Wu Bingpeng Chen Xue Zhao Qing Han Jincheng Wang | 2021 | Bio-Design and Manufacturing2021，4，1： | 4 |
| 20 | Nutrient Composition of Different Foxtail Millet Seeds显示文摘Ten millet cultivars from China and abroad were analyzed for their crude fat,amylose and amylopectin,crude protein and amino acid content. A wide variation was observed in amylopectin contain,ranging from 54. 47% to 69. 26%,while amylose content ranged from 11. 26% to 23. 22%. The average crude fat in all cultivates was 3. 46%,and most cultivates ranged from 3. 1% to 3. 7%. Protein contents ranged from 8. 61% to 15. 54% with a mean value of 11. 94%. For amino acid composition,the ten cultivates were particularly rich in leucine,and the mean was 34. 57 mg/g. The millet cultivars were also high in glycine,glutamic acid and cysteine. Millet was known to be limiting in the essential amino lysine,and the mean was 5. 18 mg/g. Other amino acids,tyrosine,histidine and arginine were also very low in the ten cultivars. In general,significant nutrient composition differences were observed between the different millet cultivars,and A2( a kind of mother line of the hybrid millet) and hybrid millet registered a higher level of protein and amino acid composition which would be useful in millet breeding. | Guangyu FAN Jincheng YUAN Lina ZHANG Xiaojie LIU Xiaoming WANG Feng WANG Xiaolei FENG Guoliang SONG Haiying ZHANG Qian WANG Zhihai ZHAO Yinghui LIU | 2018 | Agricultural Biotechnology2018，7，5： | 4 |
