| 1 | Degradation of corn stalk by the composite microbial system of MC1显示文摘MC1 的合成微生物引起的系统被用来降级玉米秸以便象 MC1 的细菌的作文一样决定降级的产品的性质。结果显示发酵肉汤的 pH 典型地代表由 MC1 的木质纤维素降级,在早阶段减少并且在降级的以后的阶段增加。微生物引起的生物资源在在降级以后的日子 3 上达到顶点。MC1 高效地降级了在将近 70% 的玉米秸在哪个期间它的纤维素内容在 71.2% 减少了,在 76.5% 的半纤维素和在 24.6% 的木质素。在发酵肉汤的水溶性的糖类(WSC ) 的内容在开始的三天期间日益增多地增加了,并且此后减少了,建议在降级过程的早阶段的 WSC 的累积。各种各样的不稳定的产品的全部的层次在降级以后在第三天内达到顶点,并且不稳定的产品的 7 种类型在发酵肉汤被检测。这些是乙醇,醋酸, 1,2-ethanediol, propanoic 酸, butanoic 酸, 3-methyl-butanoic 酸和甘油。六主要混合物是分析的份量上,每混合物的内容是乙醇(0.584 g/L ) ,醋酸(0.735 g/L ) , 1,2-ethanediol (0.772 g/L ) , propanoic 酸(0.026 g/L ) , butanoic 酸(0.018 g/L ) 和甘油(4.203 g/L ) 。基于 DNA 的 16S rDNA PCR-DGGE 分析,从文化答案收集的细菌的房间的描述证明在 MC1 的细菌的社区的作文从以前的研究与观察基本上与一致。这显示 MC1 的结构在不同木质纤维素材料的降级期间是很稳定的。 | GUO Peng WANG Xiaofen ZHU Wanbin YANG Hongyan CHENG Xu CUI Zongjun | 2008 | Journal of Environmental Sciences2008，20，1： | 39 |
| 2 | Identification of PtGai(a DELLA protein)in trifoliate orange and expression patterns in response to drought stress显示文摘Gibberellins(GAs)are an important hormone in regulating plant growth and development,and DELLA protein is an essential negative regulator of GA signal transduction.The aim of the study was to clone a GAinhibiting protein DELLA from trifoliate orange(Poncirus trifoliata L.Raf.)and to analyze the bioinformations and expression patterns of the protein gene in tissues and in response to drought stress.A DELLA protein was isolated from trifoliate orange and named as PtGai(Genebank number:MZ170959).The PtGai protein had 1731 bp open reading frames,along with 576 amino acid codes,and also grouped with sweet orange(XM_006430552.4).The PtGai protein sequence was 65%homology with the sequences of DELLA proteins in other plant families.PtGai protein existed in the nucleus based on the prediction of subcellular localization.PtGai protein could be expressed in roots,stems,and leaves,along with the highest expression in stems.PtGai was upregulated by drought stress in leaves and roots,along with the decrease of root total GA concentration and the inhibition of shoot and root biomass production.It indicated the characteristics of PtGai protein and the roles of PtGai in GA synthesis and plant growth. | XIAOFEN CHENG ABEER HASHEM ELSAYED FATHI ABD_ALLAH QIANGSHENG WU KAMIL KUČA | 2021 | BIOCELL2021，45，6： | 2 |
| 3 | Longitudinal virological changes and underlying pathogenesis in hospitalized COVID-19 patients in Guangzhou,China显示文摘Prolonged viral RNA shedding and recurrence of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in coronavirus disease 2019(COVID-19)patients have been reported.However,the clinical outcome and pathogenesis remain unclear.In this study,we recruited 43 laboratory-confirmed COVID-19 patients.We found that prolonged viral RNA shedding or recurrence mainly occurred in severe/critical patients(P<0.05).The average viral shedding time in severe/critical patients was more than 50 days,and up to 100 days in some patients,after symptom onset.However,chest computed tomography gradually improved and complete absorption occurred when SARS-CoV-2 RT-PCR was still positive,but specific antibodies appeared.Furthermore,the viral shedding time significantly decreased when the A1,430G or C12,473T mutation occurred(P<0.01 and FDR<0.01)and increased when G227A occurred(P<0.05 and FDR<0.05).High IL1R1,IL1R2,and TNFRSF21 expression in the host positively correlated with viral shedding time(P<0.05 and false discovery rate<0.05).Prolonged viral RNA shedding often occurs but may not increase disease damage.Prolonged viral RNA shedding is associated with viral mutations and host factors. | Zhengtu Li Yinhu Li Ruilin Sun Shaoqiang Li Lingdan Chen Yangqing Zhan Mingzhou Xie Jiasheng Yang Yanqun Wang Airu Zhu Guoping Gu Le Yu Shuaicheng Li Tingting Liu Zhaoming Chen Wenhua Jian Qian Jiang Xiaofen Su Weili Gu Liyan Chen Jing Cheng Jincun Zhao Wenju Lu Jinping Zheng Shiyue Li Nanshan Zhong Feng Ye | 2021 | Science China(Life Sciences)2021，64，12： | 1 |
| 4 | Quality control for ocean observations: From present to future显示文摘The quality control(QC) of ocean observational data, essential to establish a high-quality global ocean database, is one of the basic data pre-processing steps in oceanography research, marine monitoring, and forecasting. With the introduction of various advanced instruments in recent decades, oceanographic surveys have expanded from coastal regions to open oceans.However, as ocean in-situ observations are obtained using different instruments that offer heterogeneous data qualities, it is paramount that bad data could be accurately and efficiently identified via QC to provide a reliable global ocean database. In this review, we briefly summarize the latest progress of QC for oceanic in-situ observations, and mainly focus on temperature and salinity data. The similarities and differences between QC schemes developed by various ocean organizations are introduced. We also discuss the performances of the various QC schemes and identify the key challenges. Based on the discussions, several recommendations are proposed for future improvements in the QC for ocean observations. | Zhetao TAN Bin ZHANG Xiaofen WU Mingmei DONG Lijing CHENG | 2022 | Science China Earth Sciences2022，65，2： | 1 |
| 5 | Inducible expression of endomorphins in murine dendritic cells显示文摘Bone marrow precursor cells were extracted from C57BL/6J mice aged 7-8 weeks, and dendritic cells were purified using anti-CD11c (a specific marker for dendritic cells) antibody-coated magnetic beads. Immunofluorescence staining revealed that the expression levels of endomorphin-1 and endomorphin-2 were upregulated in dendritic cells activated by lipopolysaccharide. An enzyme immunoassay showed that lipopolysaccharide and other Toll-like receptor ligands promoted the secretion of endomorphin-1 and endomorphin-2 from activated dendritic cells. [3H]-thymidine incorporation demonstrated that endomorphin-1 and endomorphin-2 both inhibited the proliferation of T lymphocyte induced by activated dendritic cells. Furthermore, this immunosuppressive effect was blocked by CTOP, a specific antagonist of μ-opioid receptors. Our experimental findings indicate that activated dendritic cells can induce the expression and secretion of endomorphins, and that endomorphins suppress T lymphocyte proliferation through activation of μ-opioid receptors. | Xiaohuai Yang Hui Xia Yong Chen Xiaofen Liu Cheng Zhou Qin Gao Zhenghong Li | 2012 | Neural Regeneration Research2012，7，35： | 1 |
| 6 | Twenty years of ocean observations with China Argo显示文摘The international Argo program,a global observational array of nearly 4000 autonomous profiling floats initiated in the late 1990s,which measures the water temperature and salinity of the upper 2000 m of the global ocean,has revolutionized oceanography.It has been recognized one of the most successful ocean observation systems in the world.Today,the proposed decade action“OneArgo”for building an integrated global,full-depth,and multidisciplinary ocean observing array for beyond 2020 has been endorsed.In the past two decades since 2002,with more than 500 Argo deployments and 80 operational floats currently,China has become an important partner of the Argo program.Two DACs have been established to process the data reported from all Chinese floats and deliver these data to the GDACs in real time,adhering to the unified quality control procedures proposed by the Argo Data Management Team.Several Argo products have been developed and released,allowing accurate estimations of global ocean warming,sea level change and the hydrological cycle,at interannual to decadal scales.In addition,Deep and BGC-Argo floats have been deployed,and time series observations from these floats have proven to be extremely useful,particularly in the analysis of synoptic-scale to decadal-scale dynamics.The future aim of China Argo is to build and maintain a regional Argo fleet comprising approximately 400 floats in the northwestern Pacific,South China Sea,and Indian Ocean,accounting for 9%of the global fleet,in addition to maintaining 300 Deep Argo floats in the global ocean(25%of the global Deep Argo fleet).A regional BGC-Argo array in the western Pacific also needs to be established and maintained. | Zenghong Liu Xiaogang Xing Zhaohui Chen Shaolei Lu Xiaofen Wu Hong Li Chunling Zhang Lijing Cheng Zhaoqin Li Chaohui Sun Jianping Xu Dake Chen Fei Chai | 2023 | Acta Oceanologica Sinica2023，42，2： | 0 |
