| 1 | Bimetallic Ru-Ni/TiO2 catalysts for hydrogenation of N-ethylcarbazole:Role of TiO2 crystal structure显示文摘Hydrogenation of N-ethylcarbazole(NEC),the hydrogen lean form of a liquid organic hydrogen carrier,on TiO2 supported Ru-Ni bimetallic catalysts is investigated.Crystal structure of TiO2 plays a critical role on the hydrogenation activity and selectivity towards fully hydrogenated product.Ru/anatase catalyst exhibits higher selectivity but lower reactivity compared to Ru/rutile catalyst.Ni addition significantly promotes the performance of Ru/anatase catalyst while causes severe performance deterioration of Ru/rutile catalyst.Commercial P25,a mixture of anatase and rutile phases in approximate ratio A/R1/4,is found to be the best TiO2 support for NEC hydrogenation.Ru/P25 catalyst outperforms both Ru/rutile and Ru/anatase and its activity can be further slightly improved by Ni addition.The unexpected synergism between the two different TiO2 phases for Ru based NEC hydrogenation catalysts is related to metal-support interaction and Ru-Ni interaction. | Hongen Yu Xue Yang Yong Wu Yanru Guo Shuan Li Wei Lin Xingguo Li Jie Zheng | 2020 | Journal of Energy Chemistry2020,29,1: | 7 |
| 2 | Pertuzumab in combination with trastuzumab and chemotherapy for Chinese patients with HER2-positive metastatic gastric or gastroesophageal junction cancer:a subpopulation analysis of the JACOB trial显示文摘Background:The JACOB trial(NCT01774786)was a double-blinded,placebo-controlled,randomized,multicenter,international,phase III trial evaluating the efficacy and safety of adding pertuzumab to trastuzumab and chemo-therapy in first-line treatment of human epidermal growth factor receptor 2(HER2)-positive metastatic gastric cancer/gastroesophageal junction cancer(GEJC).The aim of this analysis was to investigate efficacy and safety outcomes in the Chinese subpopulation from the JACOB trial.Methods:This post hoc subpopulation analysis included all patients recruited in China's Mainland(n=163;20.9%)between June 2013 and January 2016.The patients were randomly assigned in a 1:1 ratio to receive pertuzumab plus trastuzumab and chemotherapy(pertuzumab group;n=82)or placebo plus trastuzumab and chemotherapy(con-trol group;n=81).Intravenous pertuzumab(840 mg)and trastuzumab(8 mg/kg loading and 6 mg/kg maintenance doses)were given every 3 weeks until disease progression or unacceptable toxicity.Chemotherapy was given as per standard regimens/doses of capecitabine or 5-fluorouracil plus cisplatin.The primary endpoint was overall survival(OS);secondary efficacy endpoints included progression-free survival(PFS),and overall objective response rate(ORR).Results:The median OS was 18.7 months in the pertuzumab group and 16.1 months in the control group(hazard ratio[HR]0.75;95%confidence interval[CI]0.49 to 1.14).The median PFS was 10.5 and 8.6 months in the pertuzumab and control groups,respectively(HR 0.85;95%CI 0.60 to 1.21),and the median ORRs were 68.9%and 55.7%,respectively.The treatment effect in this Chinese subpopulation showed consistency with that in the global ITT population with numerically lower HR for OS and PFS compared with the control group.The safety profiles of the pertuzumab and control groups in this Chinese subpopulation analysis were generally comparable.The most common grade 3-5adverse events were neutropenia,anemia,and leukopenia.However,due to the nature of being a post hoc subgroup analysis,the results presented here are descriptive only and need to be interpreted with caution.Conclusions:OS and PFS were numerically improved by adding pertuzumab to trastuzumab and chemotherapy as first-line treatment in Chinese HER2-positive gastric cancer/GEJC patients,and this regimen demonstrated an acceptable safety profile. | Tianshu Liu Yanru Qin Jin Li Ruihua Xu Jianming Xu Shujun Yang Shukui Qin Yuxian Bai Changping Wu Yixiang Mao Haiyan Wu Yilin Ge Lin Shen | 2019 | Cancer Communications2019,39,1: | 6 |
| 3 | Aerosol light absorption in a coastal city in Southeast China:Temporal variations and implications for brown carbon显示文摘Light-absorbing carbonaceous aerosols including black carbon(BC) and brown carbon(BrC)play significant roles in atmospheric radiative properties. One-year measurements of aerosol light absorption at multi-wavelength were continuously conducted in Xiamen,southeast of China in 2014 to determine the light absorption properties including absorption coefficients(σabs) and absorption ?ngstr?m exponent(AAE) in the coastal city.Light absorptions of BC and BrC with their contributions to total light absorption were further quantified. Mean σabsat 370 nm and 880 nm were 56.6 ± 34.3 and 16.5 ± 11.2 Mm-1,respectively. σabspresented a double-peaks diurnal pattern with the maximum in the morning and the minimum in the afternoon. σabswas low in warm seasons and high in cold seasons. AAE ranged from 0.26 to 2.58 with the annual mean of 1.46, implying that both fossil fuel combustion and biomass burning influenced aerosol optical properties. σabsof BrC at 370 nm was 24.0 ± 5.7 Mm-1, contributing 42% to the total absorption. The highest AAE(1.52 ± 0.02) and largest BrC contributions(47% ± 4%) in winter suggested the significant influence of biomass burning on aerosol light absorption. Long-distance air masses passing through North China Plain and the Yangtze River Delta led to high AAE and BrC contributions. High AAE value of 1.46 in July indicated that long-range transport of the air pollutants from intense biomass burning in Southeast Asia would affect aerosol light absorption in Southeast China. The study will improve the understanding of light absorption properties of aerosols and the optical impacts of BrC in China. | Yuqing Qiu Xin Wu Yanru Zhang Lingling Xu Youwei Hong Jinsheng Chen Xiaoqiu Chen Junjun Deng | 2019 | Journal of Environmental Sciences2019,31,6: | 5 |
| 4 | The landscape of gene-CDS-haplotype diversity in rice:Properties,population organization,footprints of domestication and breeding,and implications for genetic improvement显示文摘Polymorphisms within gene coding regions represent the most important part of the overall genetic diversity of rice.We characterized the gene-coding sequence-haplotype(gcHap)diversity of 45963 rice genes in 3010 rice accessions.With an average of 226±390 gcHaps per gene in rice populations,rice genes could be classified into three main categories:12865 conserved genes,10254 subspecific differentiating genes,and 22844 remaining genes.We found that 39218 rice genes carry>255179 major gcHaps of potential functional importance.Most(87.5%)of the detected gcHaps were specific to subspecies or populations.The inferred proto-ancestors of local landrace populations reconstructed from conserved predominant(ancient)gcHaps correlated strongly with wild rice accessions from the same geographic regions,supporting a multiorigin(domestication)model of Oryza sativa.Past breeding efforts generally increased the gcHap diversity of modern varieties and'caused significant frequency shifts in predominant gcHaps of 14266 genes due to independent selection in the two subspecies.Low frequencies of“favorable”gcHaps at most known genes related to rice yield in modern varieties suggest huge potential for rice improvement by mining and pyramiding of favorable gcHaps.The gcHap data were demonstrated to have greater power than SNPs for the detection of causal genes that affect complex traits.The rice gcHap diversity dataset generated in this study would facilitate rice basic research and improvement in the future. | Fan Zhang Chunchao Wang Min Li Yanru Cui Yingyao Shi Zhichao Wu Zhiqiang Hu Wensheng Wang Jianlong Xu Zhikang Li | 2021 | Molecular Plant2021,14,5: | 5 |
| 5 | Morphological and physiological analysis of narrow and striped leaf 1(nsl1) mutant of rice(Oryza sativa L.) and the gene mapping显示文摘The shape and color of rice leaves are important agronomic traits that directly influence the proportion of sunlight energy utilization and ultimately affect the yield and quality.A new mutant exhibiting stable inheritance was identified as derived from ethyl methane sulfonate(EMS)-treated restorer Jinhui 10,tentatively named as narrow and striped leaf 1(nsl1).The nsl1 displayed pale white leaves at the seeding stage and then white striped leaves in parallel to the main vein at the jointing stage.Meanwhile,its leaf blades are significantly narrower than the control group of Jinhui 10.The chloroplast structures of cells in the white striped area of the nsl1 mutant break down,and the photosynthetic pigments are significantly lower than that of the wild type.Moreover,fluorescence parameters,such as F0,F v/F m,U psII,qp,and ETR,in the nsl1 mutant are significantly lower than those of the wild type,and the photosynthetic efficiency is also significantly decreased.These changes in leaf color and shape,together with physiological changes in the nsl1,result in smaller plant height and a decrease in the most important agronomic traits,such as the number of grains per panicle,grain weight,etc.Genetic analysis shows that the narrow and striped traits of the nsl1 mutant are controlled by a single recessive nuclear gene,which is located between InDel 16and InDel 12 in chromosome 3.The physical distance is204 kb.So far,no similar genes of such leaf color and shape in this area have been reported.This study has laid a solid foundation for the gene cloning and function analysis of NSL1. | Fangming Zhao Yong Zhang Yanru Wu Tongming Wang Ling Ma Zhenglin Yang Xia Wei Xianchun Sang Yinghua Ling Nan Wang Changwei Zhang Guanghua He | 2014 | Chinese Science Bulletin2014,59,9: | 3 |
| 6 | Genome editing and animal models显示文摘Transgenic technology allows a gene of interest to be introduced into the genome of a laboratory animal,and provides an extremely powerful tool to dissect the molecular mechanisms of disease.Transgenic mouse models made by microinjection of DNA into zygotic pronuclei in particular have been widely used by the genetics community for 30 years.However,it remains a rather crude approach:injected sequences randomly insert in multiple copies as concatamers,they can be mutagenic,and they have variable or silenced expression depending on the site of integration,a phenomenon called position effects.As a result,multiple lines are required in order to confirm appropriate transgene expression.This can be partially overcome by flanking transgenes with insulator sequences to protect the transgene from the influence of the surrounding regulatory elements.Large(\300 kb)BACbased transgenic vectors have also been shown to be more resistant to position effects.However,animals carrying extra copies of fairly large regions of the genome could have unpredictable phenotypes.The most effective method used to control for position effects is to target transgene insertion to specific genomic loci,the so-called targeted transgenesis;for instance,the fast,site-specific transgenic technology Targatt TM.The purpose of this review is to provide an overview on the current existing methods for making targeted transgenic mouse models. | Ruby Yanru Chen-Tsai Ruhong Jiang Luping Zhuang Junfeng Wu Lingsong Li Jiarui Wu | 2014 | Chinese Science Bulletin2014,59,1: | 2 |

| 8 | Macrophage polarization is involved in liver fibrosis induced byβ_(1)-adrenoceptor autoantibody显示文摘Accumulating evidence suggests that liver injury can be induced by the over-expression ofβ_(1)-adrenergic receptors(β_(1)-ARs).High titers of autoantibodies specific toβ_(1)-adrenergic receptors(β_(1)-AA)are detected in the sera of heart failure patients,potentially playing agonist-like roles.However,the role ofβ_(1)-AA in liver function has not been characterized.In this study,we collect the sera of primary biliary cholangitis(PBC)patients,a condition which easily develops into liver fibrosis,and analyze the relationship between PBC andβ_(1)-AA.A passive immunization model is established to assess the effect ofβ_(1)-AA on the liver.Subsequently,the effect ofβ_(1)-AA on macrophages is investigated in vitro.Results show that PBC patients have a high titer and ratio ofβ_(1)-AA,compared to controls.Liver injury and fibrosis are induced byβ_(1)-AA.In vitro experiments with ROS probe demonstrate thatβ_(1)-AA induces macrophages to produce ROS and secrete TNFα.These effects can be partially reversed by metoprolol,a blocker forβ_(1)-AR.Results from the transwell and phagocytosis assays show thatβ_(1)-AA promotes macrophage migration and phagocytosis.FCM tests suggest thatβ_(1)-AA induces the alteration of M1 rather than M2 markers in macrophages.Finally,the Annexin V/PI assay indicates that macrophage culture supernatants stimulated byβ_(1)-AA cause hepatocyte apoptosis.Overall,these results suggest thatβ_(1)-AA is involved in PBC.Theβ_(1)-AA-induced activation,phagocytosis and phenotypic modification of macrophages may play an important role in the development of hepatic fibrosis and injury. | Ye Wu Xiongxiong Fan Haicun Yu Jingyi Liu Yanru Duan Suli Zhang Li Yan Yunhui Du Huirong Liu | 2022 | Acta Biochimica et Biophysica Sinica2022,54,8: | 1 |

| 14 | Molecular characterization of OsPRP1 from rice,which is expressed preferentially in anthers显示文摘A proline-rich protein-encoding cDNA encoded by a rice gene, OsPRP1, was isolated by PCR-mediated RNA subtraction hybridization strategy and rapid amplification of cDNA ends. The deduced protein consists of 224 amino acids with the highest level of proline residue (14.29%). Following the putative signal peptide, OsPRP1 contains two structural domains, of which the N-terminal domain lacks Pro-rich repetitive sequences, and the C-terminal domain has two repetitive proline-rich sequences of 18 amino acid residues with PEPK motifs. Southern blot and sequence analysis show that OsPRP1 exists as four copies in rice genome and is localized in rice chromosome 10. RT-PCR experiments reveal that OsPRP1 is expressed preferentially in spikelets and buds with lower levels in roots and leaves. In situ hybridization indicates that OsPRP1 transcripts are present at high levels in pollen mother cells (PMCs), meiotic PMCs, tapetal cells and vascular bundle cells of flower organs. The expression of OsPRP1 in anthers has temporal specificity. The transcripts are accumulated at high levels in PMCs, at the highest levels in meiotic PMCs and at undetectable levels in uninucleate pollen. In buds the transcripts are only detected in the epidermal cells of coleoptiles and leaf primordial. | WU Xiaohuai, MAO Aijun, WANG Rong, WANG Tai, SONG Yanru & TONG Zhe Key Laboratory of Photosynthesis and Environmental Molecular Physiology, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China Correspondence should be addressed to Wang Tai (e-mail: twang@ ns.ibcas.ac.cn) | 2003 | Chinese Science Bulletin2003,48,22: | 0 |
| 15 | Nonstoichiometric Yttrium Hydride–Promoted Reversible Hydrogen Storage in a Liquid Organic Hydrogen Carrier显示文摘N-Ethylcarbazole(NEC)is one of the most promising liquid organic hydrogen carriers(LOHCs),but its application is limited by sluggish kinetics due to lack of high-efficiency,low-cost catalysts.This work reports a cobalt(Co)-based catalyst promoted by nonstoichiometric yttrium hydride(YH_(3−x))to achieve high-efficiency,reversible hydrogen storage in NEC,with>5.5 wt%reversible hydrogen storage capacity could be achieved below 473 K,and with good kinetics.The YH_(3−x)-promoted Co-based catalyst is the first non-noble metal catalyst with high activity for NEC hydrogenation and 12H-NEC dehydrogenation reactions.A mechanistic study suggests that YH_(3−x)facilitates the reversible hydrogen transfer both in the hydrogenation and the dehydrogenation reactions.The nonstoichiometric YH_(3−x)contained both lattice H and H vacancies with tunable H chemical potential serve as the H donor and H acceptor for reversible hydrogen transfer.Our results support the practical application of LOHCs and inspire new approaches for the utilization of conventional metal hydrides to promote versatile H transfer reactions. | Yong Wu Yanru Guo Hongen Yu Xiaojing Jiang Yuxuan Zhang Yue Qi Kai Fu Lei Xie Guoling Li Jie Zheng Xingguo Li | 2021 | CCS Chemistry2021,3,3: | 0 |
