| 1 | Spatio-temporal dynamics of vegetation and its relationship with climate factors Mongolia, China coverage in Inner显示文摘The vegetation coverage dynamics and its relationship with climate factors on different spatial and temporal scales in Inner Mongolia during 2001-2010 were analyzed based on MODIS-NDVI data and climate data.The results indicated that vegetation coverage in Inner Mongolia showed obvious longitudinal zonality,increasing from west to east across the region with a change rate of 0.2/10°N.During 2001-2010,the mean vegetation coverage was 0.57,0.4 and 0.16 in forest,grassland and desert biome,respectively,exhibiting evident spatial heterogeneities.Totally,vegetation coverage had a slight increasing trend during the study period.Across Inner Mongolia,the area of which the vegetation coverage showed extremely significant and significant increase accounted for 11.25% and 29.13% of the area of whole region,respectively,while the area of which the vegetation coverage showed extremely significant and significant decrease accounted for 7.65% and 26.61%,respectively.On inter-annual time scale,precipitation was the dominant driving force of vegetation coverage for the whole region.On inter-monthly scale,the change of vegetation coverage was consistent with both the change of temperature and precipitation,implying that the vegetation growth within a year is more sensitive to the combined effects of water and heat rather than either single climate factor.The vegetation coverage in forest biome was mainly driven by temperature on both inter-annual and inter-monthly scales,while that in desert biome was mainly influenced by precipitation on both the two temporal scales.In grassland biome,the yearly vegetation coverage had a better correlation with precipitation,while the monthly vegetation coverage was influenced by both temperature and precipitation.In grassland biome,the impacts of precipitation on monthly vegetation coverage showed time-delay effects. | MU Shaojie YANG Hongfei LI Jianlong CHEN Yizhao GANG Chengcheng ZHOU Wei JU Weimin | 2013 | Journal of Geographical Sciences2013,23,2: | 28 |
| 2 | Intestinal microbiota: a potential target for the treatment of postmenopausal osteoporosis显示文摘Postmenopausal osteoporosis(PMO) is a prevalent metabolic bone disease characterized by bone loss and structural destruction, which increases the risk of fracture in postmenopausal women. Owing to the high morbidity and serious complications of PMO, many efforts have been devoted to its prophylaxis and treatment. The intestinal microbiota is the complex community of microorganisms colonizing the gastrointestinal tract. Probiotics, which are dietary or medical supplements consisting of beneficial intestinal bacteria, work in concert with endogenous intestinal microorganisms to maintain host health. Recent studies have revealed that bone loss in PMO is closely related to host immunity, which is influenced by the intestinal microbiota. The curative effects of probiotics on metabolic bone diseases have also been demonstrated. The effects of the intestinal microbiota on bone metabolism suggest a promising target for PMO management.This review seeks to summarize the critical effects of the intestinal microbiota and probiotics on PMO, with a focus on the molecular mechanisms underlying the pathogenic relationship between bacteria and host, and to define the possible treatment options. | Xin Xu Xiaoyue Jia Longyi Mo Chengcheng Liu Liwei Zheng Quan Yuan Xuedong Zhou | 2017 | Bone Research2017,5,3: | 20 |
| 3 | A Novel Secure Data Transmission Scheme in Industrial Internet of Things显示文摘The industrial Internet of Things(IoT)is a trend of factory development and a basic condition of intelligent factory.It is very important to ensure the security of data transmission in industrial IoT.Applying a new chaotic secure communication scheme to address the security problem of data transmission is the main contribution of this paper.The scheme is proposed and studied based on the synchronization of different-structure fractional-order chaotic systems with different order.The Lyapunov stability theory is used to prove the synchronization between the fractional-order drive system and the response system.The encryption and decryption process of the main data signals is implemented by using the n-shift encryption principle.We calculate and analyze the key space of the scheme.Numerical simulations are introduced to show the effectiveness of theoretical approach we proposed. | Hongwen Hui Chengcheng Zhou Shenggang Xu Fuhong Lin | 2020 | China Communications2020,17,1: | 19 |
| 4 | Desertification dynamic and the relative roles of climate change and human activities in desertification in the Heihe River Basin based on NPP显示文摘Relative roles of climate change and human activities in desertification are the hotspot of research on desertification dynamic and its driving mechanism.To overcome the shortcomings of existing studies,this paper selected net primary productivity(NPP) as an indicator to analyze desertification dynamic and its impact factors.In addition,the change trends of actual NPP,potential NPP and HNPP(human appropriation of NPP,the difference between potential NPP and actual NPP) were used to analyze the desertification dynamic and calculate the relative roles of climate change,human activities and a combination of the two factors in desertification.In this study,the Moderate Resolution Imaging Spectroradiometer(MODIS)-Normalised Difference Vegetation Index(NDVI) and meteorological data were utilized to drive the Carnegie-Ames-Stanford Approach(CASA) model to calculate the actual NPP from 2001 to 2010 in the Heihe River Basin.Potential NPP was estimated using the Thornthwaite Memorial model.Results showed that 61% of the whole basin area underwent land degradation,of which 90.5% was caused by human activities,8.6% by climate change,and 0.9% by a combination of the two factors.On the contrary,1.5% of desertification reversion area was caused by human activities and 90.7% by climate change,the rest 7.8% by a combination of the two factors.Moreover,it was demonstrated that 95.9% of the total actual NPP decrease was induced by human activities,while 69.3% of the total actual NPP increase was caused by climate change.The results revealed that climate change dominated desertification reversion,while human activities dominated desertification expansion.Moreover,the relative roles of both climate change and human activities in desertification possessed great spatial heterogeneity.Additionally,ecological protection policies should be enhanced in the Heihe River Basin to prevent desertification expansion under the condition of climate change. | Wei ZHOU ZhengGuo SUN JianLong LI ChengCheng GANG ChaoBin ZHANG | 2013 | Journal of Arid Land2013,5,4: | 18 |
| 5 | Grassland coverage inter-annual variation and its coupling relation with hydrothermal factors in China during 1982-2010显示文摘GIMMS(Global Inventory Modeling and Mapping Studies) NDVI(Normalised Difference Vegetation Index) from 1982 to 2006 and MODIS(Moderate Resolution Imaging Spectroradiometer) NDVI from 2001 to 2010 were blended to extract the grass coverage and analyze its spatial pattern. The response of grass coverage to climatic variations at annual and monthly time scales was analyzed. Grass coverage distribution had increased from northwest to southeast across China. During 1982–2010, the mean nationwide grass coverage was 34% but exhibited apparent spatial heterogeneity, being the highest(61.4%) in slope grasslands and the lowest(17.1%) in desert grasslands. There was a slight increase of the grass coverage with a rate of 0.17% per year. Increase in slope grasslands coverage was as high as 0.27% per year, while in the plain grasslands and meadows the grass coverage increase was the lowest(being 0.11% per year and 0.1% per year, respectively). Across China, the grass coverage with extremely significant increase(P<0.01) and significant increase(P<0.05) accounted for 46.03% and 11% of the total grassland area, respectively, while those with extremely significant and significant decrease accounted for only 4.1% and 3.24%, respectively. At the annual time scale, there are no significant correlations between grass coverage and annual mean temperature and precipitation. However, the grass coverage was somewhat affected by temperature in alpine and sub-alpine grassland, alpine and sub-alpine meadow, slope grassland and meadow, while grass coverage in desert grassland and plain grassland was more affected by precipitation. At the monthly time-scale, there are significant correlations between grass coverage with both temperature and precipitation, indicating that the grass coverage is more affected by seasonal fluctuations of hydrothermal conditions. Additionally, there is one-month time lag-effect between grass coverage and climate factors for each grassland types. | ZHOU Wei GANG Chengcheng CHEN Yizhao MU Shaojie SUN Zhengguo LI Jianlong | 2014 | Journal of Geographical Sciences2014,24,4: | 12 |
| 6 | Medical expenditures for colorectal cancer diagnosis and treatment: A 10-year high-level-hospital-based multicenter retrospective survey in China, 2002-2011显示文摘Objective: Colorectal cancer(CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan(CNY)using 2011 values.Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stageI cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval(95%CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011(P for trend <0.001), with a cumulative increase of 2.4 times(from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages Ⅰ, Ⅱ, Ⅲ and Ⅳ were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively(P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion(52.6%).Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China. | Jufang Shi Guoxiang Liu Hong Wang Ayan Mao Chengcheng Liu Lanwei Guo Huiyao Huang Jiansong Ren Xianzhen Liao Yana Bai Xiaojie Sun Xinyu Zhu Jialin Wang Bingbing Song Jinyi Zhou Lin Zhu Haike Lei Yuqin Liu Yunyong Liu Lingbin Du Yutong He Kai Zhang Ni Li Wanqing Chen Min Dai Jie He | 2019 | Chinese Journal of Cancer Research2019,31,5: | 8 |
| 7 | Amorphous Zr(OH)4 coated LiNi0.915Co0.075Al0.01O2 cathode material with enhanced electrochemical performance for lithium ion batteries显示文摘LiNi_(0.915)Co_(0.075)Al_(0.01)O_2(NCA) with Zr(OH)_4 coating is demonstrated as high performance cathode material for lithium ion batteries(LIBs). The coated materials are synthesized via a simple dry coating method of NCA with Zr(OH)_4 powders, and then characterized with scanning electron microscopy(SEM), transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS). Experimental results show that amorphous Zr(OH)_4 powders have been successfully coated on the surface of spherical NCA particles, exhibiting improved electrochemical performance. 0.50 wt% Zr(OH)_4 coated NCA delivers a capacity of 197.6 mAh/g at the first cycle and 154.3 mAh/g after 100 cycles with a capacity retention of 78.1% at 1 C rate. In comparison, the pure NCA shows a capacity of 194.6 mAh/g at the first cycle and 142.5 mAh/g after 100 cycles with a capacity retention of 73.2% at 1 C rate. Electrochemical impedance spectroscopy(EIS) results show that the coated material exhibits a lower resistance, indicating that the coating layer can efficiently suppress transition metals dissolution and decrease the side reactions at the surface between the electrode and electrolyte. Therefore, surface coating with amorphous Zr(OH)_4 is a simple and useful method to enhance the electrochemical performance of NCA-based materials for the cathode of LIBs. | Zhen Zhang Pengfei Zhou Huanju Meng Chengcheng Chen Fangyi Cheng Zhanliang Tao Jun Chen | 2017 | Journal of Energy Chemistry2017,26,3: | 5 |

| 10 | The chromosome-scale genome of Phoebe bournei reveals contrasting fates of terpene synthase (TPS)-a and TPS-b subfamilies显示文摘Terpenoids,including aromatic volatile monoterpenoids and sesquiterpenoids,function in defense against pathogens and herbivores.Phoebe trees are remarkable for their scented wood and decay resistance.Unlike other Lauraceae species investigated to date,Phoebe species predominantly accumulate sesquiterpenoids instead of monoterpenoids.Limited genomic data restrict the elucidation of terpenoid variation and functions.Here,we present a chromosome-scale genome assembly of a Lauraceae tree,Phoebe bournei,and identify 72 full-length terpene synthase(TPS)genes.Genome-level comparison shows pervasive lineage-specific duplication and contraction of TPS subfamilies,which have contributed to the extreme terpenoid variation within Lauraceae species.Although the TPS-a and TPS-b subfamilies were both expanded via tandem duplication in P.bournei,more TPS-a copies were retained and constitutively expressed,whereas more TPS-b copies were lost.The TPS-a genes on chromosome 8 functionally diverged to synthesize eight highly accumulated sesquiterpenes in P.bournei.The essential oil of P.bournei and its main component,b-caryophyllene,exhibited antifungal activities against the three most widespread canker pathogens of trees.The TPS-a and TPS-b subfamilies have experienced contrasting fates over the evolution of P.bournei.The abundant sesquiterpenoids produced by TPS-a proteins contribute to the excellent pathogen resistance of P.bournei trees.Overall,this study sheds light on the evolution and adaptation of terpenoids in Lauraceae and provides valuable resources for boosting plant immunity against pathogens in various trees and crops. | Xiao Han Junhong Zhang Shuang Han Sun Li Chong Guanliang Meng Minyan Song Yang Wang Shengcai Zhou Chengcheng Liu Luhuan Lou Xiongzhen Lou Longjun Cheng Erpei Lin Huahong Huang Qi Yang Zaikang Tong | 2022 | Plant Communications2022,3,6: | 3 |

| 13 | Intestinal dysbiosis exacerbates the pathogenesis of psoriasis-like phenotype through changes in fatty acid metabolism显示文摘The intestinal microbiota has been associated with host immunity as well as psoriasis;however,the mechanism of intestinal microbiota regulating psoriasis needs to be demonstrated systematically.Here,we sought to examine its role and mechanism of action in the pathogenesis of psoriasis.We found that the severity of psoriasis-like skin phenotype was accompanied by changes in the composition of the intestinal microbiota.We performed co-housing and fecal microbial transplantation(FMT)experiments using the K14-VEGF transgenic mouse model of psoriasis and demonstrated that the transfer of intestinal microbiota from mice with severe psoriasis-like skin phenotype exacerbated psoriasiform skin inflammation in mice with mild symptoms,including increasing the infiltration and differentiation of Th17,and increased the abundance of Prevotella,while decreasing that of Parabacteroides distasonis,in the colon.These alterations affected fatty acid metabolism,increasing the abundance of oleic and stearic acids.Meanwhile,gentamicin treatment significantly reduced the abundance of Prevotella and alleviated the psoriasis-like symptoms in both K14-VEGF mice and imiquimod(IMQ)-induced psoriasis-like mice.Indeed,administration of oleic and stearic acids exacerbated psoriasis-like symptoms and increased Th17 and monocyte-derived dendritic cell infiltration in the skin lesion areas in vivo,as well as increased the secretion of IL-23 by stimulating DCs in vitro.At last,we found that,treatment of PDE-4 inhibitor alleviated psoriasis-like phenotype of K14-VEGF mice accompanied by the recovery of intestinal microbiota,including the decrease of Prevotella and increase of Parabacteroides distasonis.Overall,our findings reveal that the intestinal microbiota modulates host metabolism and psoriasis-like skin inflammation in mice,suggesting a new target for the clinical diagnosis and treatment of psoriasis. | Qixiang Zhao Jiadong Yu Hong Zhou Xiaoyan Wang Chen Zhang Jing Hu Yawen Hu Huaping Zheng Fanlian Zeng Chengcheng Yue Linna Gu Zhen Wang Fulei Zhao Pei Zhou Haozhou Zhang Nongyu Huang Wenling Wu Yifan Zhou Jiong Li | 2023 | Signal Transduction and Targeted Therapy2023,8,2: | 2 |
| 14 | Olfactory and gustatory dysfunctions of COVID-19 patients in China:A multicenter study显示文摘Introduction:With the spread of the epidemic worldwide,an increasing number of doctors abroad have observed the following atypical symptoms of coronavirus disease 2019(COVID-19):olfactory or taste disorders.Therefore,clarifying the incidence and clinical characteristics of olfactory and taste disorders in Chinese COVID-19 patients is of great significance and urgency.Materials and Methods:A retrospective study was conducted,which included 229 severe acute respiratory syndrome coronavirus 2 confirmed patients,through face-to-face interviews and telephone follow-up.Following the completion of questionnaires,the patients participating in the study,were categorized according to the degree of olfactory and taste disorders experienced,and the proportion of each clinical type of patient with olfactory and taste disorders and the time when symptoms appeared were recorded.Results:Among the 229 patients,31(13.54%)had olfactory dysfunction,and 44(19.21%)had gustatory dysfunction.For the patients with olfactory dysfunction,6(19.35%)developed severe disease and became critically ill.Olfactory dysfunction appeared before the other symptoms in 21.43%of cases.The proportion of females with olfactory and gustatory dysfunction was higher than that of males(P<0.001).Conclusions:The incidence of olfactory and gustatory dysfunction was much lower than that reported abroad;the prognosis of patients with olfactory dysfunction is relatively favorable;olfactory and gustatory dysfunction can be used as a sign for early screening;females are more prone to olfactory and gustatory dysfunction. | Jianhui Li Yi Sun Enqiang Qin Hu Yuan Mingbo Liu Wenqi Yi Zhu Chen Chengcheng Huang Fengjie Zhou Ruiyao Chen Leibo Zhang Ning Yu Qiong Liu Xuejun Zhou Jingjing He Boyu Li Fusheng Wang Changliang Yang Shiming Yang | 2022 | World Journal of Otorhinolaryngology-Head and Neck Surgery2022,8,4: | 2 |
| 15 | Stable-isotope probing of bacterial community for dissolved inorganic carbon utilization in Microcystis aeruginosa-dominated eutrophic water显示文摘Dissolved inorganic carbon(DIC) is an important source of carbon in aquatic ecosystems,especially under conditions of increased frequency of cyanobacterial bloom. However, the importance of bacteria in direct or indirect utilization of DIC has been widely overlooked in eutrophic freshwater. To identify the functional bacteria that can actively utilize DIC in eutrophic freshwater during cyanobacterial bloom, stable-isotope probing(SIP) experiments were conducted on eutrophic river water with or without inoculation with cyanobacteria(Microcystis aeruginosa). Our 16 S rRNA sequencing results revealed the significance of Betaproteobacteria, with similar relative abundance as Alphaproteobacteria, in the active assimilation of H^(13)CO^(3-) into their DNA directly or indirectly, which include autotrophic genera Betaproteobacterial ammonia-oxidizing bacteria. Other bacterial groups containing autotrophic members, e.g. Planctomycetes and Nitrospira, also presented higher abundance among free-living bacteria in water without cyanobacteria. Microcystis aggregates showed a preference for some specific bacterial members that may utilize H^(13)CO^(3-) metabolized by Microcystis as organic matter, e.g. Bacteroidetes(Cytophagales, Sphingobacteriales), and microcystindegrading bacteria Betaproteobacteria(Paucibacter/Burkholderiaceae). This study provides some valuable information regarding the functional bacteria that can actively utilize DIC in eutrophic freshwater. | Weiguo Zhang Jiangye Li Chengcheng Wang Xue Zhou Yan Gao Zhongjun Jia | 2019 | Journal of Environmental Sciences2019,31,5: | 1 |
| 16 | TPE based aggregation induced emission fluorescent sensors for viscosity of liquid and mechanical properties of hydrogel显示文摘Two amphiphilic TPE E/Z isomers with aggregation induced emission(AIE)property have been synthesized and characterized.The logarithmic fluorescent intensity of the two molecules was in positive relationship with logarithmic viscosity of liquid.To note,the Z-TPE isomer exhibited more sensitivity in the viscosity of liquid sensing in comparison with the corresponding E-TPE counterpart(around 1.80 folds).Furthermore,two molecules could be used as fluorescent sensors for mechanical properties(viscosity and storage modulus)of hydrogel as well.In addition,two sensors displayed low cytotoxicity in normal tissue cell line(L929)within the concentration range of 2–10μmol/L.These results potentially promised their applications as fluorescent sensors for mechanical properties in the fields of biological and biomedical. | Na Wang Hang Yao Qi Tao Jing Sun Hao Ma Yang Wang ChengCheng Zhou Hongying Fan Hongxia Shao Aijian Qin Dawei Su Chenyin Wang Hui Chong | 2022 | Chinese Chemical Letters2022,33,1: | 1 |

| 18 | Association of low cadmium and mercury exposure with chronic kidney disease among Chinese adults aged≥80 years:A cross-sectional study显示文摘Background:The heavy metals cadmium(Cd)and mercury(Hg)are known to be widespread environmental contaminants and high occupational exposure adversely affects the risk of chronic kidney disease(CKD).However,evidence from epidemiological studies linking low Cd and Hg exposure(or non-industrial)to the risk of progression to CKD are conflicting.This study aimed to explore the association of low Cd and Hg exposure with the risk of CKD in Chinese adults aged≥80 years.Methods:The participants were recruited for the Healthy Aging and Biomarkers Cohort Study in 2017,an ongoing perspective survey conducted in longevity areas in China initially involving 3016 older adults.We used logistic regression models to estimate odds ratios(ORs)with 95%confidence intervals of CKD setting Cd and Hg as categorical variables.Logistic regression with restricted cubic spline was used to characterize a dose-response relationships between Cd or Hg concentrations and the risk of CKD in the study population.Results:The ORs for the risk of CKD comparing the fourth to the first quartile of blood Cd,blood Hg,urine Cd,and urine Hg were 1.77,1.57,2.03,and 1.50,respectively.Restricted cubic spline models showed that blood Cd and urine Hg were significantly linearly correlated with the risk of CKD,while blood Hg and urine Cd were non-linearly correlated with the risk of CKD with a steeper slope at concentrations<2.30μg/L and 3.30μg/g creatinine.Conclusions:Our findings suggest that even low Cd and Hg exposure(or non-industrial)were associated with increased risk of CKD in Chinese oldest old,although we did not find a significant multiplicative and additive interaction between Cd and Hg levels in relation to the risk of CKD. | Yuan Wei Yuebin Lyu Zhaojin Cao Feng Zhao Yingchun Liu Chen Chen Chengcheng Li Heng Gu Feng Lu Jinhui Zhou Bing Wu Yang Liu Juan Li Xiaoming Shi | 2022 | Chinese Medical Journal2022,135,24: | 1 |
| 19 | Enhanced thermoelectric performance in Ga_(x)Co_(4)Sb_(12.3-y)Te_(y) skutterudites via suppressing bipolar effects for commercial application显示文摘The n-type filled and doped skutterudites Ga_(x)Co_(4)Sb_(12.3) and Ga_(0.2)Co_(4)Sb_(11.3)Te composites with the welldistributed GaSb nanoinclusions are synthesized through the manipulating of metastable Ga fillers and enrichment of Sb by an in-situ method with a proper annealing procedure.Ga atoms can fill the icosahedron cages of skutterudite at high temperature,but at low temperature,they are driven out from the lattice voids and form the second phase of GaSb at grain boundaries.The presence of GaSb second phases reduces the thermal conductivity effectively.Te doping leads to a significant increase in carrier concentration of Ga_(0.2)Co_(4)Sb_(11.3)Te,thus largely suppresses the bipolar effect of Ga_(x)Co_(4)Sb_(12.3),resulting in a great enhancement in power factor.Moreover,Te doping induces mass and strain fluctuation,which decreases the lattice thermal conductivity further.Consequently,the maximum ZT is increased from 0.56 for Ga_(0.2)Co_(4)Sb_(12.3) at 573 K to 1.48 for Ga_(0.2)Co_(4)Sb_(11.3)Te at 873 K,which is advantageous to improve the thermoelectric conversion efficiency for commercial application. | Jing Jiang Rui Zhang Chengcheng Yang Yi Niu Ting Zhou Yan Pan Chao Wang | 2020 | Journal of Materiomics2020,6,2: | 0 |
| 20 | Self-reporting fluorescence deciphers the antibacterial nature of cationic amphiphiles:Monomer or aggregate?显示文摘Cationic amphiphile aggregates exhibit superior antibacterial activity than monomers.However,the antimicrobial mechanism of aggregates has not been well understood because it is difficult to distinguish and monitor aggregate and monomer in antimicrobial process.Herein,three bola-type cationic amphiphiles with aggregation-induced emission property have been developed to show distinguishable fluorescence in their monomer and aggregate.The hydrophilicity of monomer and the stability of aggregate are finely tuned by tailoring the linkers between two quaternary ammonium end groups and tetraphenylethylene skeleton.The sensitive fluorescence switching of monomer and aggregate achieves the quantitative monitoring of dynamic interaction of three amphiphiles with bacteria.The aggregates with cationic charges first attach to bacterial surface,and the monomers subsequently dissociate from aggregates to penetrate bacterial membrane.Further,our results reveal the vital role of stability of aggregates during antimicrobial process,shedding light on the rational design of high-efficient antimicrobials. | Chengcheng Zhou Zeyu Ding Weijiang Guan Ben Zhong Tang | 2023 | Aggregate2023,4,5: | 0 |
