1Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
2The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
3Metaverse:Perspectives from graphics,interactions and visualization显示文摘The metaverse is a visual world that blends the physical world and digital world.At present,the development of the metaverse is still in the early stage,and there lacks a framework for the visual construction and exploration of the metaverse.In this paper,we propose a framework that summarizes how graphics,interaction,and visualization techniques support the visual construction of the metaverse and user-centric exploration.We introduce three kinds of visual elements that compose the metaverse and the two graphical construction methods in a pipeline.We propose a taxonomy of interaction technologies based on interaction tasks,user actions,feedback and various sensory channels,and a taxonomy of visualization techniques that assist user awareness.Current potential applications and future opportunities are discussed in the context of visual construction and exploration of the metaverse.We hope this paper can provide a stepping stone for further research in the area of graphics,interaction and visualization in the metaverse.Yuheng Zhao Jinjing Jiang Yi Chen Richen Liu Yalong Yang Xiangyang Xue Siming Chen 2022Visual Informatics2022,6,1:10
4Effect of rare earth on the microstructure and mechanical properties of as-cast Cu-30Ni alloy显示文摘Cu-30Ni-xRE (x=0-0.213) alloys were prepared by a metal mould casting method. The effect of RE on the microstructure and mechanical properties of the alloys was investigated using optical microscope, scanning electronic microscope with energy-dispersive spectrometer, X-ray diffraction, and mechanical test. The results show that RE has obvious effect on refining dendrite structure and grain size, as well as on purifying the melting of Cu-30Ni alloy. With the increase of RE content, the ultimate tensile strength, yield strength, and elongation increase at first and then decrease after adding RE more than 0.095 wt.%. Cu-30Ni-0.095RE alloy possesses preferable mechanical properties, i.e., the ultimate tensile strength, yield strength, and elongation are 308 MPa, 125 MPa, and 51.2%, respectively. The microstructure and mechanical properties are worsened with increasing RE content more than 0.095 wt.%. The improvement of mechanical properties of Cu-30Ni-0.095RE alloy is attributed to RE refining microstructure and purifying the matrix.MAO Xiangyang FANG Feng JIANG Jianqing TAN Rongsheng 2009Rare Metals2009,28,6:9
5Modulation of Gut Microbiota in Pathological States显示文摘人类微生态是寄居在人体中的微生物聚集体,且主要存在于胃肠道(GIT)中。肠道微生态随着人体发育而演化,并在人类健康和疾病中起着重要作用。近年来,由于微生态会影响宿主代谢、生理学和免疫系统发育,而且微生态紊乱可能导致许多疾病,其越来越受到人们的关注。肠道微生态可能与恶性肿瘤有一定联系,如胃癌和结直肠癌;也可能与其他一些疾病有关,如非酒精性脂肪肝(NAFLD)、被称为工业化世界'生活方式疾病'的肥胖和糖尿病、冠心病以及中枢神经系统紊乱。虽然分子技术革命为我们更准确地研究肠道微生态提供了必要的工具,但是我们需要更精确地阐明其与某些人类疾病病理变化的关系,明确微生态在不同疾病中的作用是新的治疗策略发展的基础。本文概述了肠道微生态对人类健康的重要影响以及调整肠道菌群结构的潜在用途,如菌群移植用于治疗耐药艰难梭菌(C.difficile)的感染。通过微生态干预调整肠道区域以改善人类健康的概念虽刚刚兴起,但其治疗意义显著。因此,抑制有害菌、促进有益菌可能会保护人类健康,并且这些努力将为探索发展更加合理的治疗方案打下基础。Yulan Wang BaohongWang Junfang wu xiangyang Jiang Huiru Tang Ole H.

6High-quality de novo assembly of the Eucommia ulmoides haploid genome provides new insights into evolution and rubber biosynthesis显示文摘We report the acquisition of a high-quality haploid chromosome-scale genome assembly for the first time in a tree species,Eucommia ulmoides,which is known for its rubber biosynthesis and medicinal applications.The assembly was obtained by applying PacBio and Hi–C technologies to a haploid that we specifically generated.Compared to the initial genome release,this one has significantly improved assembly quality.The scaffold N50(53.15 MB)increased 28-fold,and the repetitive sequence content(520 Mb)increased by 158.24 Mb,whereas the number of gaps decreased from 104,772 to 128.A total of 92.87%of the 26,001 predicted protein-coding genes identified with multiple strategies were anchored to the 17 chromosomes.A new whole-genome duplication event was superimposed on the earlierγpaleohexaploidization event,and the expansion of long terminal repeats contributed greatly to the evolution of the genome.The more primitive rubber biosynthesis of this species,as opposed to that in Hevea brasiliensis,relies on the methylerythritol-phosphate pathway rather than the mevalonate pathway to synthesize isoprenyl diphosphate,as the MEP pathway operates predominantly in trans-polyisoprene-containing leaves and central peels.Chlorogenic acid biosynthesis pathway enzymes were preferentially expressed in leaves rather than in bark.This assembly with higher sequence contiguity can foster not only studies on genome structure and evolution,gene mapping,epigenetic analysis and functional genomics but also efforts to improve E.ulmoides for industrial and medical uses through genetic engineering.Yun Li Hairong Wei Jun Yang Kang Du Jiang Li Ying Zhang Tong Qiu Zhao Liu Yongyu Ren Lianjun Song Xiangyang Kang 2020Horticulture Research2020,7,1:7
7The Medium Energy X-ray telescope (ME) onboard the Insight-HXMT astronomy satellite显示文摘The Medium Energy X-ray telescope(ME) is one of the three main telescopes on board the Insight hard X-ray modulation telescope(Insight-HXMT) astronomy satellite. ME contains 1728 pixels of Si-PIN detectors sensitive in 5-30 ke V with a total geometrical area of 952 cm^2. The application specific integrated circuit(ASIC) chip, VA32TA6, is used to achieve low power consumption and low readout noise. The collimators define three kinds of field of views(FOVs) for the telescope, 1°×4°, 4°×4°,and blocked ones. Combination of such FOVs can be used to estimate the in-orbit X-ray and particle background components.The energy resolution of ME is ~3 ke V at 17.8 ke V(FWHM) and the time resolution is 255 μs. In this paper, we introduce the design and performance of ME.XueLei Cao WeiChun Jiang Bin Meng WanChang Zhang Tao Luo Sheng Yang ChunLei Zhang YuDong Gu Liang Sun XiaoJing Liu JiaWei Yang Xian Li Ying Tan ShaoZhen Liu YuanYuan Du FangJun Lu YuPeng Xu Ju Guan ShuangNan Zhang HuanYu Wang TiPei Li ChengMo Zhang XiangYang Wen JinLu Qu LiMing Song XiaoBo Li MingYu Ge YuPeng Zhou ShaoLin Xiong Shu Zhang YongJie Zhang ZeHao Cheng Fei Zhang MaoShun Li XiaoHua Liang Min Gao EnBo Yang XiaoHang Liu HongWei Liu YiJung Yang Fan Zhang 2020Science China(Physics,Mechanics & Astronomy)2020,63,4:5
8Materials Experiment on Tiangong-2 Space Laboratory显示文摘During the China's Tiangong-2(TG-2) flight mission, the experiments of 18 kinds of material samples were conducted in space by using a Multiple Materials Processing Furnace(MMPF) mounted in the orbital module of the TG-2 space laboratory. After the experiments of 12 kinds of samples of the first and second batches were completed successfully, astronauts packed and brought them back to the ground by ShenzhouII spacecraft. By studying processing and formation on semiconductor and optoelectronics materials, metal alloys and metastable materials, functional single-crystal, micro-and nano-composite materials encapsulated in sample ampoules both in space and on Earth, we expect to explore some physical and chemical processes and mechanism of the materials formation that are normally obscured and therefore are difficult to study quantitatively on the ground due to the gravity-induced convection, to obtain the processing and synthesis technology for preparing high quality materials, and lead to the improvement and development of materials processing techniques on Earth, and also develop the experiment device and comprehensive ability for materials experiment in microgravity environment. This report briefly introduces the main points of each research work and preliminary comparative analysis results of 12 samples carried out by scientists undertaking research task.LI Xiangyang LU Ye MENG Xiangjian WANG Jianlu WANG Reng CHEN Lidong HUA Zile LI Xiaoya SHI Jianlin LIU Jinfeng XU Guisheng WEI Bingbo XIE Wenjun YIN Zhigang ZHANG Xingwang JIANG Hongxiang LI Hong LUO Xinghong ZHANG Haifeng ZHAO Jiuzhou WANG Binbin PAN Mingxiang 2018空间科学学报2018,38,5:4
9TiO2/EDTA-rich carbon composites: Synthesis, characterization and visible-light-driven photocatalytic reduction of Cr(Ⅵ)显示文摘Ti02/EDTA-rich carbon composites(TiO_2/EDTA-RC) have been successfully synthesized via a low temperature carbonization process. TiO_2/EDTA-RC exhibits marked absorption of visible light and excellent photoreduction of Cr(Ⅵ) activity under visible light irradiation(λ>420 nm). Due to the high carboxyl group content and strong coordination ability of EDTA, TiO_2-EDTA complex can be easily fabricated between EDTA incorporated in carbon sheet and titanol group on the surface of TiO_2. TiO_2-EDTA complexes on the surface of TiO_2/EDTA-RC, the LMCT complex, are responsible for the prominent photoreduction of Cr(Ⅵ) properties of Ti02/EDTA-RC under visible light irradiation. In addition, the unique structure ofTiO_2/EDTA-RC is also propitious to the visible-light photocatalytic reduction of Cr(Ⅵ).Carbon sheet of TiO_2/EDTA-RC acts as a supporter. TiO_2 nanoparticles and EDTA homogeneously disperse into the carbon sheet supporter and form the TiO_2-EDTA complexes, which can avoid the aggregation of TiO_2 nanoparticles in the aqueous solution and provide more photocatalytic reaction points for the reduction of Cr(Ⅵ).Zhijun Luo Lingling Qu Jianzhong Ji Jing wang Suying Jiang Zhiren WU Xiangyang Wu 2018Chinese Chemical Letters2018,29,3:3
10Climatology and seasonal variability of satellite-derived chlorophyll a around the Shandong Peninsula显示文摘The chlorophyll a(Chl a)is an important indicator of marine ecosystems.The spatiotemporal variation of the Chl a greatly aff ects the mariculture and marine ranching in coastal waters of the Shandong Peninsula.In the current study,the climatology and seasonal variability of surface Chl-a concentration around the Shandong Peninsula are investigated based on 16 years(December 2002-November 2018)of satellite observations.The results indicate that the annual mean Chl-a concentration is greater in the Bohai Sea than in the Yellow Sea and decreases from coastal waters to off shore waters.The highest Chl-a concentrations are found in Laizhou Bay(4.2-8.0 mg/m^(3)),Haizhou Bay(4.2-5.9 mg/m^(3))and the northeast coast of the Shandong Peninsula(4.4-5.0 mg/m^(3)),resulting from the combined eff ects of the intense riverine input and long residence time caused by the concave shape of the coastline.The seasonal Chl-a concentration shows a significant spatial variation.The Chl-a concentrations in these three subregions generally exhibit an annual maximum in August/September,due to the combined eff ects of sea surface temperature,river discharge and sea surface wind.In the southeast coast region,however,the Chl-a concentration is lowest throughout the year and reaches a maximum in February with a minimum in July,forced by the seasonal evolution of the Yellow Sea Cold Water and monsoon winds.The interannual Chl-a concentration trends vary among regions and seasons.There are significant increasing trends over a large area around Haizhou Bay from winter to summer,which are mainly caused by the rising sea surface temperature and eutrophication.In other coastal areas,the Chl-a concentration shows decreasing trends,which are clearest in summer and induced by the weakening land rainfall.This study highlights the differences in the Chl-a dynamics among regions around the Shandong Peninsula and is helpful for further studies of coupled physical-ecological-human interactions at multiple scales.Xiukai SONG Yanzhen GU Fangguo ZHAI Peiliang LI Pengxia LIU Zizhou LIU Wenfan WU Yaozu CHEN Xiangyang JIANG Jianlong HE 2021Journal of Oceanology and Limnology2021,39,4:3
11Microstructure, tensile properties and creep behavior of Al-12Si-3.5Cu-2Ni-0.8Mg alloy produced by different casting technologies显示文摘The relationship between the as-cast microstructure and mechanical properties of the Al-12 Si-3.5 Cu-2 Ni-0.8 Mg alloys produced by permanent mold casting(PMC) and high pressure die casting(HPDC)is investigated. The alloys in both PMC and HPDC consist of Al, Si, Al_5 Cu_2 Mg_8 Si_6, Al_3 Cu Ni, and Al_7 Cu_4 Ni phase. However, the microstructure of the HPDC alloy is significantly refined. Compared to the PMC alloy,the ultimate tensile strength of the HPDC alloy is significantly increased from 244 MPa to 310 MPa, while the elongation shows a reverse trend at room temperature. At low stress and temperature range, slight variations of stress exponent and activation energy indicate that the minimum creep rate is controlled by the grain boundary creep. Then the minimum creep rate is higher for the specimen with the smaller grain size, where grain boundary creep is the dominant creep mechanism. At high stress region, the stress exponent for the PMC alloy and HPDC alloy is 5.18 and 3.07, respectively. The different stress exponents and activation energies measured at high stress and high temperature range indicates that the creep mechanism varies with the casting technologies.Lijie Zuo Bing Ye Jian Feng Xiangyang Kong Haiyan Jiang Wenjiang Ding 2018Journal of Materials Science & Technology2018,34,7:3
12Antibiotics-mediated intestinal microbiome perturbation aggravates tacrolimus-induced glucose disorders in mice显示文摘Both immunosuppressants and antibiotics (ABX) are indispensable for transplant patients. However, the former increases the risk of new-onset diabetes, whereas the latter impacts intestinal microbiota (IM). It is still unclear whether and how the interaction between immunosuppressants and ABX alters the IM and thus leads to glucose metabolism disorders. This study examined the alterations of glucose and lipid metabolism and IM in mice exposed to tacrolimus (TAC) with or without ABX. We found that ABX further aggravated TAC-induced glucose tolerance and increased insulin secretion. Combined treatment resulted in exacerbated lipid accumulation in the liver. TAC-altered microbial community was further amplified by ABX administration, as characterized by reductions in phylum Firmicutes, family Lachnospiraceae, and genus Copyococcus. Analyses based on the metagenomic profiles revealed that ABX augmented the effect of TAC on microbial metabolic function mostly related to lipid metabolism. The altered components of gut microbiome and predicted microbial functional profiles showed significant correlation with hepatic lipid accumulation and glucose disorders. In conclusion, ABX aggravated the effect of TAC on the microbiome and its metabolic capacities, which might contribute to hepatic lipid accumulation and glucose disorders. These findings suggest that the ABX-altered microbiome can amplify the diabetogenic effect of TAC and could be a novel therapeutic target for patients.Yuqiu Han Xiangyang Jiang Qi Ling Li Wu Pin Wu Ruiqi Tang Xiaowei Xu Meifang Yang Lijiang Zhang Weiwei Zhu Baohong Wang Lanjuan Li 2019Frontiers of Medicine2019,13,4:3
13“Color Revolutions” and Beyond显示文摘“Color revolutions” (or “orange revolutions”) broke out in some of the Commonwealth of Independent States in the past couple of years, reminiscent of the drama of disintegration of the former Soviet bloc at the turn of the 1990s.

14Muscle-fiber array inspired,multiple-mode,pneumatic artificial muscles through planar design and one-step rolling fabrication显示文摘Advances in development of artificial muscles have enabled creation of soft robots with biological dexterity and self-adaption in unstructured environments;however,production of scalable artificial muscles with multiple-mode actuations remains elusive.Inspired by muscle-fiber arrays in muscular hydrostats,we present a class of versatile artificial muscles called MAIPAMs(muscle-fiber array inspired pneumatic artificial muscles),capable of multiple-mode actuations(such as parallel elongation-bending-spiraling actuations,10 parallel bending actuations and cascaded elongation-bending-spiraling actuations).Our MAIPAMs consist of active 3D elastomer-balloon arrays reinforced by a passive elastomer membrane,achieved through a planar design and one-step rolling fabrication approach.We introduce prototypical designs for the MAIPAMs and demonstrate their muscle-mimic structures and versatility,as well as their scalable ability to integrate flexible but non-stretchable layers for contraction and twisting actuation modes and compliant electrodes for self-sensing.We further demonstrate that this class of artificial muscles shows potential for versatile robotic applications,such as carrying a camera for recording videos,gripping or manipulating objects,and climbing a pipe-line.Jiang Zou Miao Feng Ningyuan Ding Peinan Yan Haipeng Xu Dezhi Yang Nicholas X.Fang Guoying Gu Xiangyang Zhu 2021National Science Review2021,8,10:3
15Understanding the mechanisms of resistance to tomato leaf mold:A review显示文摘Tomato leaf mold is a common disease in tomato production and severely impacts the growth,fruit quality and yield of tomato plants.Research on tomato leaf mold has a long history and has focused mainly on the differentiation of pathogen races,the structure and function of pathogen Avr gene products,the cloning of Cf resistance genes and the analysis of disease resistance mechanisms.Interactions between Cf and Avr are in accordance with the'gene-for-gene'hypothesis and typical Cf/Avr interactions are part of effector-triggered immunity(ETI).However,an increasing number of studies have proven that pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI)is involved in the disease resistance response system mediated by Cf genes.In addition,different Cf genes have both similar and different roles in the disease resistance response,indicating that the disease resistance mechanism of Cf genes is complex.In this paper,progress in tomato leaf mold research was reviewed,and the regulatory mechanism underlying the Cf-mediated disease resistance response was thoroughly explored.We hope this summary will lay a foundation for research on tomato leaf mold disease resistance mechanisms and is applicable to breeding for disease resistance.Tingting Zhao Tong Pei Jingbin Jiang Huanhuan Yang He Zhang Jingfu Li Xiangyang Xu 2022Horticultural Plant Journal2022,8,6:2

18Sensitivity of supplementation of thyroid hormone on treatmentof idiopathic short-stature children during therapy withrecombinant human growth hormone显示文摘This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of childrenwith idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormonetherapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lowerFT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroupwas treated with L-T4 (0.5-3.0 g/(kg, d)) from the beginning of the study, and the non-L-T4-treated subgroupreceived placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as thehigher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulatinghormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lowerheight velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treatedsubgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV comparedwith children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormonedeficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.Wei Wang Shuqin Jiang Zhirui Cui Xiangyang Luo Lingli Shi Heli Zheng 2018Frontiers of Medicine2018,12,5:2

20Effects of dietary cottonseed meal protein hydrolysate on growth,antioxidants and immunity of Chinese mitten crab Eriocheir Sinensis显示文摘One hundred and sixty crabs(average initial weight:51.32±0.08 g)were fed with four experimental diets containing cottonseed meal protein hydrolysate(CPH)at 0%(CPH0,control),0.3%(CPH0.3),0.6%(CPH0.6),and 1.2%CPH(CPH1.2).The experiment results show that no difference was observed in specific growth rate and survival rate of crabs fed with CPH diet.Moisture content of crabs fed with CPH0.6 diet was significantly reduced than that of the CPH0 group.Superoxide dismutase and catalase activities of crabs fed with CPH0.6 diet were significantly increased and the difference was not significant between the CPH0.3 and CPH0.6 groups.Malondialdehyde content of CPH0.3 group was significantly lower than that of the CPH0 group.Lysozyme,alkaline phosphatase,and acid phosphatase activities of CPH0.3 diet crabs were significantly higher than that of the CPH0 group.Glutamic-pyruvic transaminase activity of crabs fed with CPH0.3 diet was significantly decreased compared to the CPH0 group.The relative expression levels of Toll1,Toll2,MyD88,LITAF,and ILF-2 of crabs fed with CPH0.3 diet were significantly higher than that of the CPH0 group.The expression level of SOCS2 showed an opposite pattern.After CPH perfusion,the expression levels of SOCS2 and Toll1 in intestine at time 3 h and SOCS2 in hepatopancreas at time 18 h increased significantly to the highest value.The expression level of Toll2,MyD88,LITAF,decreased at times 6 h,6 h,12 h,respectively,then increased gradually.Therefore,supplementation of dietary CPH could improve antioxidant capacity and immune function;the appropriate supplement dosage of CPH for crab could be 0.3%-0.6%.Furthermore,the short-term CPH stimulation could significantly increase or decline the expression levels of immune-related genes at different times after CPH perfusion.CHENG Huihui LIU Wenbin YUAN Xiangyang JIA Erteng ZHANG Dingdong JIANG Guangzhen 2020Journal of Oceanology and Limnology2020,38,3:2
