| 1 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014,57,1: | 106 |
| 2 | Phosphate removal from wastewater by model-La(Ⅲ)zeolite adsorbents显示文摘Phosphorus is one of the primary nutrients which leads to eutrophication and accelerates aging process in enclosed water bodies. Because of the poor phosphorus selectivity of other adsorbents, the novel La(III)-modified zeolite adsorbent (LZA) was prepared by modifying 90 nm zeolite with lanthanide to selectively remove phosphate in the presence of various omnipresent anions, such as sulfates, bicarbonates, and chlorides. Through batch and fixed bed operation, the following optimum conditions were obtained: concentration of lanthanum chloride solution 0.05 mol/L; solid/liquor ratio 1/25; pH 10; calcination temperature 550°C; time 1 h. The value of the Freundlich model constants Kf and 1/n were found to be 16.76 mg/L and 0.2209, respectively. In addition, when calculated at pH 6.0, distribution coefficient KD could be as high as 36.6. Furthermore, in the alkaline pH range, solution of 0.8 mol/L NaCl was used to regenerate the saturated LZA, which could reach the high regeneration efficiency as high as 100%. Because of the good selectivity and regenerability of LZA, it might serve as a potential way for advanced phosphate removal from the sewage containing other anions. | NING Ping BART Hans-Jorg LI Bing LU Xiwu ZHANG Yong | 2008 | Journal of Environmental Sciences2008,20,6: | 30 |
| 3 | Changes of protein oxidation,lipid oxidation and lipolysis in Chinese dry sausage with different sodium chloride curing salt content显示文摘The effect of sodium chloride(NaCl)curing salt content on protein oxidation,lipid oxidation and lipolysis of Chinese dry sausage was investigated.Two groups Chinese dry sausages with 2%and 4%(m/m)salt content were studied.The degree of protein oxidation increased during the processes in two groups sausages,while the content of phospholipids decreased,neutral lipids and free fatty acids increased.The degree of protein oxidation,lipid oxidation and lipolysis in 4%NaCl content group was higher than those in 2%NaCl content group,while 4%NaCl content group has higher lipase activity.In conclusion,4%NaCl may facilitate the protein oxidation,lipid hydrolysis and oxidation in Chinese dry sausage,and the protein oxidation had strong correlation with lipid oxidation and lipolysis.The results could provide a basis for improving the technology of industrial production. | Bing Zhao Huimin Zhou Shunliang Zhang Xiaoqian Pan Su Li Ning Zhu Qianrong Wu Shouwei Wang Xiaoling Qiao Wenhua Chen | 2020 | Food Science and Human Wellness2020,9,4: | 22 |
| 4 | The Intervention Effect of Rosiglitozone in Ovarian Fibrosis of PCOS Rats显示文摘Objective To explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats.Methods 60 female SD rats were randomly divided into 3 groups:control group,model group and treatment group.The model and treatment groups were established by subcutaneous injection of DHEA,while the treatment group was given RGZ.The serum hormone values,pathohistology of ovarian structure of rats,ovarian ultrastructure and the expressions of TGF-β 1 and CTGF were detected.Results The PCOS model was established successfully.The expression intensity of TGF-β 1 and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400,respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133;after treatment with rosiglitazone,the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group (P<0.05,P<0.001).The values in serum of the PCOS groups were 3.749±2.054 and 0.265±0.129,and 1.914±1.801 and 0.096±0.088 in the control group which had statistically significant difference (P<0.05,P<0.001).After treatment with rosiglitazone,the values were 2.3100±1.825 and 0.112±0.187 and were significantly different with those of the model group (P<0.05,P<0.001).Conclusion TGF-β 1 and CTGF play an important role in the development of ovary fibrosis in PCOS.However,RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β 1 and CTGF. | MIAO Zhu Lin GUO Liang WANG Yong Xia CUI Rong YANG Ning HUANG Mi Qiong QIN Wei Bing CHEN Jin LI Hong Mei WANG Zi Neng WEI Xiang Cai | 2012 | Biomedical and Environmental Sciences2012,25,1: | 14 |
| 5 | Effects of planting patterns on yield, quality, and defoliation in machine-harvested cotton显示文摘The aim of this study was to elucidate the effects of different machine-harvested cotton-planting patterns on defoliation,yield,and fiber quality in cotton and to provide support for improving the quality of machine-harvested cotton.In the 2015 and 2016 growing seasons,the Xinluzao 45(XLZ45)and Xinluzao 62(XLZ62)cultivars,which are primarily cultivated in northern Xinjiang,were used as study materials.Conventional wide-narrow row(WNR),wide and ultra-narrow row(UNR),wide-row spacing with high density(HWR),and wide-row spacing with low density(LWR)planting patterns were used to assess the effects of planting patterns on defoliation,yield,and fiber quality.Compared with WNR,the seed cotton yields were significantly decreased by 2.06–5.48%for UNR and by 2.50–6.99%for LWR,respectively.The main cause of reduced yield was a reduction in bolls per unit area.The variation in HWR yield was–1.07–1.07%with reduced bolls per unit area and increased boll weight,thus demonstrating stable production.In terms of fiber quality indicators,the planting patterns only showed significant effects on the micronaire value,with wide-row spacing patterns showing an increase in the micronaire values.The defoliation and boll-opening results showed that the number of leaves and dried leaves in HWR was the lowest among the four planting patterns.Prior to the application of defoliating agent and before machine-harvesting,the numbers of leaves per individual plant in HWR were decreased by 14.45 and 25.00%on average,respectively,compared with WNR,while the number of leaves per unit area was decreased by 27.44 and 36.21%on average,respectively.The rates of boll-opening and defoliation in HWR were the highest.Specifically,the boll-opening rate before defoliation and machine-harvesting in HWR was 44.54 and 5.94%higher on average than in WNR,while the defoliation rate prior to machine-harvesting was 3.45%higher on average than in WNR.The numbers of ineffective defoliated leaves and leaf trash in HWR were the lowest,decreased by 33.40 and 32.43%,respectively,compared with WNR.In conclusion,the HWR planting pattern is associated with a high and stable yield,does not affect fiber quality,promotes early maturation,and can effectively decrease the amount of leaf trash in machine-picked seed cotton,and thus its use is able to improve the quality of machine-harvested cotton. | WANG Fang-yong HAN Huan-yong LIN Hai CHEN Bing KONG Xian-hui NING Xin-zhu WANG Xu-wen YU Yu LIU Jing-de | 2019 | Journal of Integrative Agriculture2019,18,9: | 14 |

| 7 | Meningeal lymphatic vessels regulate brain tumor drainage and immunity显示文摘Recent studies have shown that meningeal lymphatic vessels(MLVs),which are located both dorsally and basally beneath the skull,provide a route for draining macromolecules and trafficking immune cells from the central nervous system(CNS)into cervical lymph nodes(CLNs),and thus represent a potential therapeutic target for treating neurodegenerative and neuroinflammatory diseases.However,the roles of MLVs in brain tumor drainage and immunity remain unexplored.Here we show that dorsal MLVs undergo extensive remodeling in mice with intracranial gliomas or metastatic melanomas.RNA-seq analysis of MLV endothelial cells revealed changes in the gene sets involved in lymphatic remodeling,fluid drainage,as well as inflammatory and immunological responses.Disruption of dorsal MLVs alone impaired intratumor fluid drainage and the dissemination of brain tumor cells to deep CLNs(dCLNs).Notably,the dendritic cell(DC)trafficking from intracranial tumor tissues to dCLNs decreased in mice with defective dorsal MLVs,and increased in mice with enhanced dorsal meningeal lymphangiogenesis.Strikingly,disruption of dorsal MLVs alone,without affecting basal MLVs or nasal LVs,significantly reduced the efficacy of combined anti-PD-1/CTLA-4 checkpoint therapy in striatal tumor models.Furthermore,mice bearing tumors overexpressing VEGF-C displayed a better response to anti-PD-1/CTLA-4 combination therapy,and this was abolished by CCL21/CCR7 blockade,suggesting that VEGF-C potentiates checkpoint therapy via the CCL21/CCR7 pathway.Together,the results of our study not only demonstrate the functional aspects of MLVs as classic lymphatic vasculature,but also highlight that they are essential in generating an efficient immune response against brain tumors. | Xueting Hu Qiuping Deng Lu Ma Qingqing Li Yidong Chen Yuhan Liao Fan Zhou Chen Zhang Linlin Shao Jun Feng Tubao He Weihai Ning Yan Kong Yingqing Huo Aibin He Bing Liu Jingjing Zhang Ralf Adams Yulong He Fuchou Tang Xiuwu Bian Jincai Luo | 2020 | Cell Research2020,30,3: | 11 |
| 8 | Investigation on Work-Related Musculoskeletal Disorders--China, 2018−2019显示文摘What is already known about this topic?Work-related musculoskeletal disorders(WMSDs)have a high prevalence and seriously harmful,which has attracted extensive attention in various countries in the world.Currently,the occurrence and rules of WMSDs in key industries are not known in China.What is added by this report?The prevalence of WMSDs is relatively high among professional populations in key industries in China,with the most commonly affected body parts concentrated in neck,shoulders,and low back and increasing with age and working years.What are the implications for public health practice?This study determined the prevalence and distribution characteristics of WMSDs in key industries in China and provided scientific evidence to recommend for inclusion of WMSDs in the new revision of the list of occupational diseases in China. | Ning Jia Huadong Zhang Ruijie Ling Yimin Liu Gang Li Zaoliang Ren Yan Yin Hua Shao Hengdong Zhang Bing Qiu Meibian Zhang Dayu Wang Qiang Zeng Rugang Wang Jianchao Chen Danying Zhang Liangying Mei Yongquan Liu Jixiang Liu Chengyun Zhang Tianlai Li Qing Xu Ying Qu Xueyan Zhang Xin Sun Zhongxu Wang | 2020 | China CDC weekly2020,2,18: | 11 |
| 9 | Actively priming autophagic cell death with novel transferrin receptor-targeted nanomedicine for synergistic chemotherapy against breast cancer显示文摘Recently, considerable attention in the field of cancer therapy has been focused on the mammalian rapamycin target(m TOR), inhibition of which could result in autophagic cell death(ACD). Though novel combination chemotherapy of autophagy inducers with chemotherapeutic agents is extensively investigated, nanomedicine-based combination therapy for ACD remains in infancy. In attempt to actively trigger ACD for synergistic chemotherapy, here we incorporated autophagy inducer rapamycin(RAP) into 7 pep-modified PEG-DSPE polymer micelles(7 pep-M-RAP) to specifically target and efficiently priming ACD of MCF-7 human breast cancer cells with high expression of transferrin receptor(Tf R). Cytotoxic paclitaxel(PTX)-loaded micelle(7 pep-M-PTX) was regarded as chemotherapeutic drug model. We discovered that with superior intracellular uptake in vitro and more tumor accumulation of micelles in vivo, 7 pep-M-RAP exhibited excellent autophagy induction and synergistic antitumor efficacy with 7 pep-M-PTX. Mechanism study further revealed that 7 pep-M-RAP and 7 pep-MPTX used in combination provided enhanced efficacy through induction of both apoptosis-and mitochondria-associated autophagic cell death. Together, our findings suggested that the targeted excess autophagy may provide a rational strategy to improve therapeutic outcome of breast cancer, and simultaneous induction of ACD and apoptosis may be a promising anticancer modality. | Dong Mei Binlong Chen Bing He Haibin Liu Zhiqiang Lin Jialiang Lin Xiaoyan Zhang Ning Sun Libo Zhao Xiaoling Wang Qiang Zhang | 2019 | Acta Pharmaceutica Sinica B2019,9,5: | 8 |
| 10 | Protective effects of ACLF sera on metabolic functions and proliferation of hepatocytes co-cultured with bone marrow MSCs in vitro显示文摘AIM:To investigate whether the function of hepatocytes co-cultured with bone marrow mesenchymal stem cells (MSCs) could be maintained in serum from acute-onchronic liver failure (ACLF) patients.METHODS:Hepatocyte supportive functions and cytotoxicity of sera from 18 patients with viral hepatitis B-induced ACLF and 18 healthy volunteers were evaluated for porcine hepatocytes co-cultured with MSCs and hepatocyte mono-layered culture,respectively.Chemokine profile was also examined for the normal serum and liver failure serum.RESULTS:Hepatocyte growth factor (HGF) and Tumor necrosis factor;tumor necrosis factor (TNF)-α were remarkably elevated in response to ACLF while epidermal growth factor (EGF) and VEGF levels were significantly decreased.Liver failure serum samples induced a higher detachment rate,lower viability and decreased liver support functions in the homo-hepatocyte culture.Hepatocytes co-cultured with MSCs could tolerate the cytotoxicity of the serum from ACLF patients and had similar liver support functions compared with the hepatocytes cultured with healthy human serum in vitro.In addition,cocultured hepatocytes maintained a proliferative capability despite of the insult from liver failure serum.CONCLUSION:ACLF serum does not impair the cell morphology,viability,proliferation and overall metabolic capacities of hepatocyte co-cultured with MSCs in vitro. | Xiao-Lei Shi Jin-Yang Gu Yue Zhang Bing Han Jiang-Qiang xiao Xian-Wen Yuan Ning Zhang Yi-Tao Ding | 2011 | World Journal of Gastroenterology2011,17,19: | 8 |
| 11 | The geomechanics of Shenhua carbon dioxide capture and storage(CCS) demonstration project in Ordos Basin,China显示文摘Carbon dioxide(CO_2) capture and storage(CCS) is considered widely as one of promising options for CO_2emissions reduction,especially for those countries with coal-dominant energy mix like China.Injecting and storing a huge volume of CO_2 in deep formations are likely to cause a series of geomechanical issues,including ground surface uplift,damage of caprock integrity,and fault reactivation.The Shenhua CCS demonstration project in Ordos Basin,China,is the first and the largest full-chain saline aquifer storage project of CO_2 in Asia.The injection started in 2010 and ended in 2015.during which totally 0.3 million tonnes(Mt) CO_2 was injected.The project is unique in which CO_2 was injected into 18 sandstone formations simultaneously and the overlying coal seams will be mined after the injection stopped in 2015.Hence,intense geomechanical studies and monitoring works have been conducted in recent years,including possible damage resulting from the temperature difference between injected CO_2 and formations,injection induced stress and deformation change,potential failure mode and safety factor,interaction between coal mining and CO_2 geological storage,determination of injection pressure limit,and surface monitoring by the interferometric synthetic aperture radar(InSAR) technology.In this paper,we first described the background and its geological conditions of the Shenhua CCS demonstration project.Then,we gave an introduction to the coupled thermo-hydro-mechano-chemical(THMC) processes in CO_2 geological storage,and mapped the key geomechanical issues into the THMC processes accordingly.Next,we proposed a generalized geomechanical research flowchart for CO_2 geological storage projects.After that,we addressed and discussed some typical geomechanical issues,including design of injection pressure limit.CO_2 injection induced near-field damage,and interaction between CO_2geological storage and coal mining,in the Shenhua CCS demonstration project.Finally,we concluded some insights to this CCS project. | Xiaochun Li Qi Li Bing Bai Ning Wei Wei Yuan | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016,8,6: | 8 |
| 12 | A novel wheat NAC transcription factor,Ta NAC_(30), negatively regulates resistance of wheat to stripe rust显示文摘NAC transcription factors are widespread in the plant kingdom and play essential roles in the transcriptional regulation of defense responses. In this study, we isolated a novel NAC transcription factor gene, Ta NAC_(30),from a c DNA library constructed from wheat(Triticum aestivum) plants inoculated with the stripe rust pathogen Puccinia striiformis f. sp. tritici(Pst). Ta NAC_(30) contains a typical NAM domain and localizes to the nucleus. Yeast one-hybrid assays revealed that Ta NAC_(30) exhibits transcriptional activity and that its C-terminus is necessary for the activation of transcription. Expression of Ta NAC_(30) increased when host plants were infected with a virulent race(CYR_(31)) of the rust fungus Pst. Silencing of Ta NAC_(30) byvirus-induced gene silencing inhibited colonization of the virulent Pst isolate CYR_(31). Moreover, detailed histological analyses showed that silencing of Ta NAC_(30) enhanced resistance to Pst by inducing a significant increase in the accumulation of H_2O_2. Finally, we overexpressed Ta NAC_(30) in fission yeast and determined that cell viability was severely reduced in Ta NAC_(30)-transformed cells grown on medium containing H_2O_2. These results suggest that Ta NAC_(30) negatively regulates plant resistance in a compatible wheat-Pst interaction. | Bing Wang Jinping Wei Na Song Ning Wang Jing Zhao Zhensheng Kang | 2018 | Journal of Integrative Plant Biology2018,60,5: | 6 |
| 13 | The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus. | Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang | 2016 | Science China(Life Sciences)2016,59,9: | 5 |
| 14 | Removal of radioactive cesium from solutions by zinc ferrocyanide显示文摘Adsorption of ^(134)Cs from aqueous solution by zinc fcrrocyanide,and the effect of experimental conditions on the adsorption were investigated.Preliminary results showed that zinc ferrocyanide was very efficient as an absorbent.Over 98% of ^(134)Cs could be removed by zinc ferrocyanide of 0.33 g·L^(-1) from ^(134)Cs solution (Co) of 3.2~160.0 kBq·L^(-1),with adsorption capacities (Q) of 9.6~463.0 kBq·g^(-1).The adsorption equilibrium time was within one hour and the suitable pH ranged 1~10.No significant differences on ^(134)Cs adsorption were observed at 0~50℃,or in solutions containing Ca^(2+),Fe^(3+),Mg^(2+),HCO_3^-,CO_3^(2-),Cl and SO_4^(2-),even though they are 1000 times higher than the anions or cations in groundwater.However,the adsorption rates decreased when solutions contained K^+ or Na^+.The adsorption process could be described by Frcundlich and Langmuir adsorption equations. | LI Bing LIAO Jiali WU Jiaojiao ZHANG Dong ZHAO Jun YANG Yuanyou CHENG Qiong FENG Yue LIU Ning | 2008 | Nuclear Science and Techniques2008,19,2: | 5 |
| 15 | Improvement of catalytic stability for CO_2 reforming of methane by copper promoted Ni-based catalyst derived from layered-double hydroxides显示文摘Copper-promoted nickel-based metal nanoparticles(NPs) with high dispersion and good thermal stability were derived from layered-double hydroxides(LDHs) precursors that were facilely developed by a coprecipitation strategy.The copper-promoted Ni-based metal NPs catalysts were investigated for methane reforming with carbon dioxide to hydrogen and syngas.A series of characterization techniques including XRD,N_2 adsorption and desorption,H_2-TPR,XPS,CO_2-TPD,TEM,TGA and in situ CH_4-TPSR were utilized to determine the structure-function relationship for the obtained catalysts.The copper addition accelerated the catalyst reducibility as well as the methane activation,and made the Ni species form smaller NPs during both preparation and reaction by restricting the aggregation.However,with higher copper loading,the derived catalysts were less active during methane reforming with CO_2 to syngas.It was confirmed that the catalyst with 1 wt%Cu additive gave the higher catalytic activity and remained stable during long time reaction with excellent resistance to coking and to sintering.Furthermore,the mean size of metal NPs changed minimally from 6.6 to 7.9 nm even after 80 h of time on stream at temperature as high as700℃ for this optimized catalyst.Therefore,this high dispersed anti-coking copper-promoted nickel catalyst derived from LDHs precursor could be prospective catalyst candidate for the efficient heterogeneous catalysis of sustainable CO_2 conversion. | Bing Li Zhenxin Xu Fangli Jing Shizhong Luo Ning Wang Wei Chu | 2016 | Journal of Energy Chemistry2016,25,6: | 5 |
| 16 | De novo assembly of a Tibetan genome and identification of novel structural variants associated with high-altitude adaptation显示文摘Structural variants(SVs) may play important roles in human adaptation to extreme environments such as high altitude but have been under-investigated. Here, combining long-read sequencing with multiple scaffolding techniques, we assembled a high-quality Tibetan genome(ZF1), with a contig N50 length of 24.57 mega-base pairs(Mb) and a scaffold N50 length of 58.80 Mb. The ZF1 assembly filled 80 remaining N-gaps(0.25 Mb in total length) in the reference human genome(GRCh38). Markedly, we detected17 900 SVs, among which the ZF1-specific SVs are enriched in GTPase activity that is required for activation of the hypoxic pathway. Further population analysis uncovered a 163-bp intronic deletion in the MKL1 gene showing large divergence between highland Tibetans and lowland Han Chinese. This deletion is significantly associated with lower systolic pulmonary arterial pressure, one of the key adaptive physiological traits in Tibetans. Moreover, with the use of the high-quality de novo assembly, we observed a much higher rate of genome-wide archaic hominid(Altai Neanderthal and Denisovan) shared non-reference sequences in ZF1(1.32%–1.53%) compared to other East Asian genomes(0.70%–0.98%),reflecting a unique genomic composition of Tibetans. One such archaic hominid shared sequence-a662-bp intronic insertion in the SCUBE2 gene-is enriched and associated with better lung function(the FEV1/FVC ratio) in Tibetans. Collectively, we generated the first high-resolution Tibetan reference genome, and the identified SVs may serve as valuable resources for future evolutionary and medical studies. | Ouzhuluobu Yaoxi He Haiyi Lou Chaoying Cui Lian Deng Yang Gao Wangshan Zheng Yongbo Guo Xiaoji Wang Zhilin Ning Jun Li Bin Li Caijuan Bai Baimakangzhuo Gonggalanzi Dejiquzong Bianba Duojizhuoma Shiming Liu Tianyi Wu Shuhua Xu Xuebin Qi Bing Su | 2020 | National Science Review2020,7,2: | 4 |
| 17 | Recent advances in the development of nanomedicines for the treatment of ischemic stroke显示文摘Ischemic stroke is still a serious threat to human life and health,but there are few therapeutic options available to treat stroke because of limited blood-brain penetration.The development of nanotechnology may overcome some of the problems related to traditional drug development.In this review,we focus on the potential applications of nanotechnology in stroke.First,we will discuss the main molecular pathological mechanisms of ischemic stroke to develop a targeted strategy.Second,considering the important role of the blood-brain barrier in stroke treatment,we also delve mechanisms by which the blood-brain barrier protects the brain,and the reasons why the therapeutics must pass through the blood-brain barrier to achieve efficacy.Lastly,we provide a comprehensive review related to the application of nanomaterials to treat stroke,including liposomes,polymers,metal nanoparticles,carbon nanotubes,graphene,black phosphorus,hydrogels and dendrimers.To conclude,we will summarize the challenges and future prospects of nanomedicine-based stroke treatments. | Xing Tian Taojian Fan Wentian Zhao Ghulam Abbas Bo Han Ke Zhang Nan Li Ning Liu Weiyuan Liang Hao Huang Wen Chen Bing Wang Zhongjian Xie | 2021 | Bioactive Materials2021,6,9: | 4 |
| 18 | TRP (transient receptor potential) ion channel family:structures, biological functions and therapeutic interventions for diseases显示文摘Transient receptor potential(TRP)channels are sensors for a variety of cellular and environmental signals.Mammals express a total of 28 different TRP channel proteins,which can be divided into seven subfamilies based on amino acid sequence homology:TRPA(Ankyrin),TRPC(Canonical),TRPM(Melastatin),TRPML(Mucolipin),TRPN(NO-mechano-potential,NOMP),TRPP(Polycystin),TRPV(Vanilloid).They are a class of ion channels found in numerous tissues and cell types and are permeable to a wide range of cations such as Ca^(2+),Mg^(2+),Na^(+),K^(+),and others.TRP channels are responsible for various sensory responses including heat,cold,pain,stress,vision and taste and can be activated by a number of stimuli.Their predominantly location on the cell surface,their interaction with numerous physiological signaling pathways,and the unique crystal structure of TRP channels make TRPs attractive drug targets and implicate them in the treatment of a wide range of diseases.Here,we review the history of TRP channel discovery,summarize the structures and functions of the TRP ion channel family,and highlight the current understanding of the role of TRP channels in the pathogenesis of human disease.Most importantly,we describe TRP channel-related drug discovery,therapeutic interventions for diseases and the limitations of targeting TRP channels in potential clinical applications. | Miao Zhang Yueming Ma Xianglu Ye Ning Zhang Lei Pan Bing Wang | 2023 | Signal Transduction and Targeted Therapy2023,8,8: | 4 |
| 19 | Development of volatiles and odor-active compounds in Chinese dry sausage at different stages of process and storage显示文摘The effect of process and storage on the volatiles and odorant profi le of Chinese dry sausage was evaluated,as well as its physicochemical parameters.Microbial esterification and wine(27.54%–43.35%),and lipid oxidation(11.30%–34.92%)played a key role in flavor profile during process and storage.A significant increase of each volatile was detected during process except gradual decrease of volatiles from spices,while a gradual decrease of each volatile was detected during storage except signifi cant increase of volatiles from lipid oxidation and esterifi cation.15 and 6 odor-active compounds were respectively correlated(P<0.05)with the process and storage time.Level of heptanal,1-octen-3-ol,the ethyl of 2-methylbutanoic,3-methylbutanoic,butanoic,benzoic,hexanoic,heptanoic,octanoic and decanoic acid were best discriminators of process stage,while(E)-2-nonenal,ethyl hexanoate,ethyl heptanoate,and methyl decanoate,were marker compounds of storage time.An objective method was established to evaluate the stages of process and storage for samples. | Huimin Zhou Bing Zhao Shunliang Zhang Qianrong Wu Ning Zhu Su Li Xiaoqian Pan Shouwei Wang Xiaoling Qiao | 2021 | Food Science and Human Wellness2021,10,3: | 4 |
| 20 | A novel aldo-keto reductase gene, IbAKR, from sweet potato confers higher tolerance to cadmium stress in tobacco显示文摘High concentrations of Cd can inhibit growth and reduce the activity of the photosynthetic apparatus in plants. In several plant species, aldo-keto reductases(AKRs) have been shown to enhance tolerance to various abiotic stresses by scavenging cytotoxic aldehydes;however, few AKRs have been reported to enhance Cd stress tolerance. In this study, the gene Ib AKR was isolated from sweet potato. The relative expression levels of Ib AKR increased significantly(approximately 3-fold) after exposure to 200 mmol$L–1 Cd Cl2 or 10 mmol$L–1 H2 O2. A subcellular localization assay showed that Ib AKR is predominantly located in the nucleus and cytoplasm.Ib AKR-overexpressing tobacco plants showed higher tolerance to Cd stress than wild-type(WT). Transgenic lines showed a significant ability to scavenge malondialdehyde(MDA) and methylglyoxal(MG). In addition,proline content and superoxide dismutase activity were significantly higher and H2 O2 levels were significantly lower in the transgenic plants than in the WT. Quantitative real-time PCR analysis showed that the reactive oxygen species(ROS) scavenging genes encoding guaiacol peroxidase(GPX), ascorbate peroxidase(APX), monodehydroascorbate reductase(MDHAR) and peroxidase(POD) were significantly upregulated in transgenic plants compared to WT under Cd stress. These findings suggest that overexpressing Ib AKR enhances tolerance to Cd stress via the scavenging of cytotoxic aldehydes and the activation of the ROS scavenging system. | Jinxi HUO Bing DU Sifan SUN Shaozhen HE Ning ZHAO Qingchang LIU Hong ZHAI | 2018 | Frontiers of Agricultural Science and Engineering2018,5,2: | 4 |
