1Preliminary analysis of spatiotemporal pattern of global land surface water显示文摘Land surface water(LSW) is one of the most important resources for human survival and development, and it is also a main component of global water recycling. A full understanding of the spatial distribution of land surface water and a continuous measuring of its dynamics can support to diagnose the global ecosystem and environment. Based on the Global Land 30-water 2000 and Global Land 30-water 2010 products, this research analyzed the spatial distribution pattern and temporal fluctuation of land surface water under scale-levels of global, latitude and longitude, continents, and climate zones. The Global Land 30-water products were corrected the temporal inconsistency of original remotely sensed data using MODIS time-series data, and then calculated the indices such as water area, water ration and coefficient of spatial variation for further analysis. Results show that total water area of land surface is about 3.68 million km2(2010), and occupies 2.73% of land area. The spatial distribution of land surface water is extremely uneven and is gathered mainly in mid- to high-latitude area of the Northern Hemisphere and tropic area. The comparison of water ratio between 2000 and 2010 indicates the overall fluctuation is small but spatially differentiated. The Global Land 30-water products and the statistics provided the fundamental information for analyzing the spatial distribution pattern and temporal fluctuation of land surface water and diagnosing the global ecosystem and environment.CAO Xin CHEN Jun CHEN LiJun LIAO AnPing SUN FangDi LI Yang LI Lei LIN ZhongHui PANG ZhiGuo CHEN Jin HE ChaoYing PENG Shu 2014Science China Earth Sciences2014,57,10:8
2A flow cytometer based protocol for quantitative analysis of bloom-forming cyanobacteria(Microcystis) in lake sediments显示文摘A quantitative protocol for the rapid analysis of Microcystis cells and colonies in lake sediment was developed using a modified flow cytometer,the CytoSense.For cell enumeration,diluted sediment samples containing Microcystis were processed with sonication to disintegrate colonies into single cells.An optimized procedure suggested that 5 mg dw(dry weight)/mL dilution combined with 200 W × 2 min sonication yielded the highest counting efficiency.Under the optimized determination conditions,the quantification limit of this protocol was 3.3×10 4 cells/g dw.For colony analysis,Microcystis were isolated from the sediment by filtration.Colony lengths measured by flow cytometry were similar to those measured by microscopy for the size range of one single cell to almost 400 μm in length.Moreover,the relationship between colony size and cell number was determined for three Microcystis species,including Microcystis flos-aquae,M.aeruginosa and M.wessenbergii.Regression formulas were used to calculate the cell numbers in differentsized colonies.The developed protocol was applied to field sediment samples from Lake Taihu.The results indicated the potential and applicability of flow cytometry as a tool for the rapid analysis of benthic Microcystis.This study provided a new capability for the high frequency monitoring of benthic overwintering and population dynamics of this bloom-forming cyanobacterium.Quan Zhou Wei Chen Huiyong Zhang Liang Peng Liming Liu Zhiguo Han Neng Wan Lin Li Lirong Song 2012Journal of Environmental Sciences2012,24,9:5
3Multi-dimensional overall regulatory modes and threshold values for water cycle of the Haihe River Basin显示文摘In this study, a multi-dimensional critical regulatory criteria and decision-making mechanism based on the scientific cognition of multi-dimensional attributes and characteristics of the water cycle was proposed. This system was functioned by deeply discriminating the nature-society binary characteristics of the five-dimensional characteristics of the water cycle system of the Haihe River Basin (water resources, economy, society, ecology, and environment) under the influence of high-intensity human activities and hydrological changes and by analyzing the organic interactive relationships between the five dimensions and their overall effect on the water cycle. A GDP calculation model was constructed in this study by adjusting the water environment for water resources, after which five-dimensional normalization objective functions were established for multi-objective analysis to carry out trade-off analysis of multi-dimensional regulatory indexes. In addition, synergetic theory, entropy theory and dissipation structure theory were introduced to construct an evaluation model for multi-dimensional regulatory schemes. A water cycle multi-dimensional critical overall regulatory model system was also established. This system consisted of a multi-objective macroeconomic model (DAMOS), water resource allocation model based on rules (ROWAS), evaluation model for WEDP (EMW) and multi-dimensional regulatory scheme evaluation model (SEAMUR) as the main body. To address the national demands faced by the Haihe River Basin as a result of combinatorial schemes for different hydrological series and water amounts diverted by the south-to-north water diversion project, this study adopted a hierarchy progression method to set up the technologies, investigated multi-dimensional overall regulatory methods, proposed an overall regulation threshold value for the water cycle of the Haihe River Basin, and recommended corresponding five-dimensional regulatory schemes.GAN Hong WANG Lin CAO YinBai YOU JinJun GAN ZhiGuo QIN ChangHai HE Shan XU Kai 2013Chinese Science Bulletin2013,58,27:4

7Preheating method of lithium-ion batteries in an electric vehicle显示文摘To improve the low-temperature charge-discharge performance of lithium-ion battery,low-temperature experiments of the charge-discharge characteristics of 35 Ah high-power lithium-ion batteries have been conducted,and the wide-line metal film method for heating batteries is presented.At-40℃,heating and charge-discharge experiments have been performed on the battery pack.The results indicate the charge-discharge performance is substantially worse in cold climates,and can be significantly improved by heating the battery pack with a wide-line metal film.Pulse charge-discharge experiments show that at-40℃ambient temperature,the heated battery pack can charge or discharge at high current and offer almost80%power.Zhiguo LEI Chengning ZHANG Junqiu LI Guangchong FAN Zhewei LIN 2015Journal of Modern Power Systems and Clean Energy2015,3,2:2
8Analysis of the chromatin binding af?nity of retrotransposases reveals novel roles in diploid and tetraploid cotton显示文摘LTR-retrotransposable elements are major components of diploid(Gossypium arboreum) and tetraploid(Gossypium hirsutum) cotton genomes that have undergone dramatic increases in copy number during the course of evolution. However, little is known about the biological functions of LTR-retrotransposable elements in cotton. Here, we show that a copia-like LTRretrotransposable element has maintained considerable activity in both G. arboreum and G. hirsutum. We identified two functional domains of the retrotransposon and analyzed their expression levels in various cotton tissues, including leaves, ovules, and germinating seeds.ChIP-qPCR(chromatin immunoprecipitation followed by quantitative PCR), using a copia-specific antibody,established that copia-like proteins primarily bind to the first exons of several protein-coding genes in cotton cells. This finding suggests that retrotransposons play a novel, important role in regulating the transcriptional activities of protein-coding genes with various biological activities.Jing Lin Ying Cai Gai Huang Yan Yang Yang Li Kun Wang Zhiguo Wu 2019Journal of Integrative Plant Biology2019,61,1:2

14Maternal heterozygous mutation in CHEK1 leads to mitotic arrest in human zygotes显示文摘Dear Editor,The first mitotic division in zygotes is crucial for the beginning of the life cycle for the human.After fertilization,zygotes reactivate cell cycle,both paternal and maternal genomes replicate and reprogram to become totipotent.In the meantime,the male and female pronucleus move to the center of the zygote and merge.Then zygotes enter the metaphase,and sister chromatids separate into two daughter cells(Eckersley-Maslin et al.,2018;Reichmann et al.,2018).This is a sensitive time window and many perturbances may cause the first mitosis to fail.Beili Chen Jianying Guo Ting Wang Qianhui Lee Jia Ming Fangfang Ding Haitao Li Zhiguo Zhang Lin Li Yunxia Cao Jie Na 2022Protein & Cell2022,13,2:1

16Cotton functional genomics reveals global insight into genome evolution and fiber development显示文摘Due to the economic value of natural textile fiber, cotton has attracted much research attention, which has led to the publication of two diploid genomes and two tetraploid genomes. These big data facilitate functional genomic study in cotton, and allow researchers to investigate cotton genome structure, gene expression, and protein function on the global scale using high-throughput methods. In this review, we summarized recent studies of cotton genomes. Population genomic analyses revealed the domestication history of cultivated upland cotton and the roles of transposable elements in cotton genome evolution.Alternative splicing of cotton transcriptomes was evaluated genome-widely. Several important gene families like MYC, NAC, Sus and GhPLDal were systematically identified and classified based on genetic structure and biological function. High-throughput proteomics also unraveled the key functional proteins correlated with fiber development. Functional genomic studies have provided unprecedented insights into global-scale methods for cotton research.Zhiguo Wu Yan Yang Gai Huang Jing Lin Yuying Xia Yuxian Zhu 2017Journal of Genetics and Genomics2017,44,11:1
17The potential of ionic liquids in biopharmaceutical engineering显示文摘Biopharmaceuticals,such as proteins,peptides,nucleic acids and vaccines,bring about great hopes for the prevention and treatment of various diseases,but the industrialization of these products still faces challenges such as structural instability,inefficient bioactivity and low bioavailability.Ionic liquids(ILs),the marvelous solvent media with inimitable and tunable properties,may provide alternative solutions to overcome the above problems of biopharmaceutical industry.Progress has gradually been made through studies by combination of ILs with biomacromolecules.The applications involved the stabilization,protection,and delivery of biopharmaceuticals.Recent trends are being forwarded to using ILs in vaccines and nucleic acid drugs.However,challenges remain on the toxicity and safety issues.Besides,the cost of adding ILs to the benefits of biopharmaceuticals need to be considered.Xuan Lin Zhiguo Su Yanli Yang Songping Zhang 2021Chinese Journal of Chemical Engineering2021,34,2:1

20Identification of key genes underlying the effects of obesity on knee osteoarthritis显示文摘To the Editor:Osteoarthritis(OA)is a disease associated with high morbidity and disability.Obesity,typically measured as a body mass index(BMI)≥30 kg/m2,is a well-known risk factor for the onset of OA and its related complications.[1]Interestingly,these two diseases may have common underlying mechanisms which contribute to the pathogenesis,such as genetic changes,and these mechanisms have not yet been fully explored.Gene expression profiling is a powerful tool used to systematically identify the molecular features underlying genetic variations associated with complex multifactorial diseases such as OA.In addition,it has been shown the significance of gene expression in understanding the mechanisms in the pathogenesis of obesity and OA.[2]This study hypothesized that hub genes could explain the relationship between obesity and OA.Consequently,identifying that these genes are involved could provide insights into the detailed regulatory mechanisms of obesity on OA.Siming Dai Juan Zhang Xiaoying Zhu Yuxuan Lin Ying Cui Zhiyi Zhang Zhiguo Lin 2022Chinese Medical Journal2022,,4:1
