1IL-23-induced macrophage polarization and its pathological roles in mice with imiquimod-induced psoriasis显示文摘Macrophages acquire distinct phenotypes during tissue stress and inflammatory responses.Macrophages are roughly categorized into two different subsets named inflammatory M1 and anti-inflammatory M2 macrophages.We herein identified a unique pathogenic macrophage subpopulation driven by IL-23 with a distinct gene expression profile including defined types of cytokines.The freshly isolated resting mouse peritoneal macrophages were stimulated with different cytokines in vitro,the expression of cytokines and chemokines were detected by microarray,real-time PCR,ELISA and multiple colors flow cytometry.Adoptive transfer of macrophages and imiquimod-induced psoriasis mice were used.In contrast to M1-and M2-polarized macrophages,IL-23-treated macrophages produce large amounts of IL-17A,IL-22and IFN-γ.Biochemical and molecular studies showed that IL-23 induces IL-17A expression in macrophages through the signal transducer and activator of transcription 3(STAT3)-retinoid related orphan receptor-γ T (RORyT)pathway.T-bet mediates the IFN-γ production in IL-23-treated macrophages.Importantly,IL-23-treated macrophages signifi- cantly promote the dermatitis pathogenesis in a psoriasis-like mouse model.IL-23-treated resting macrophages express a distinctive gene expression prolife compared with M1 and M2 macrophages.The identification of IL-23-induced macrophage polarization may help us to understand the contribution of macrophage subpopulation in Th17-cytokines-related pathogenesis.Yuzhu Hou Linnan Zhu Hongling Tian Hai-Xi Sun Ruoyu Wang Lianfeng Zhang Yong Zhao 2018Protein & Cell2018,9,12:16

3Comparison of schemes for preparing magnetic Fe_3O_4 nanoparticles显示文摘Magnetic Fe3O4 nanoparticles were prepared by means of coprecipitation using NH3·H2O in water and in alcohol, and using NaOH in water. A series of instruments such as SEM, TEM, HRTEM, FT-IR, XRD and VSM were used to characterize the properties of the magnetic nanoparticles. The results indicated that the magnetism of Fe3O4 nanoparticles synthesized using NH3·H2O in water was the highest, although the reaction time was the longest. The process using NaOH in water was the simplest and the reaction time was the shortest, but the particle characteristics were inferior to those of the other two methods. The mean size of magnetic Fe3O4 nanoparticles prepared by coprecipitation in alcohol was the smallest among the three, but the nanoparticles aggregated severely. The magnetic Fe3O4 nanoparticles were coated with oleic acid using saturated sodium oleate, and the polarity of the surface-modified nanoparticles was measured. Fe3O4 nanoparticles prepared using NH3·H2O, not NaOH, could be coated successfully and thoroughly.Ruoyu Hong Jianhua Li Jian Wang Hongzhong Li 2007China Particuology2007,5,1:5

5Combined and synergistic effects of climate change and urbanization on water quality in the Wolf Bay watershed,southern Alabama显示文摘This study investigated potential changes in flow, total suspended solid(TSS) and nutrient(nitrogen and phosphorous) loadings under future climate change, land use/cover(LULC)change and combined change scenarios in the Wolf Bay watershed, southern Alabama,USA. Four Global Circulation Models(GCMs) under three Special Report Emission Scenarios(SRES) of greenhouse gas were used to assess the future climate change(2016–2040). Three projected LULC maps(2030) were employed to reflect different extents of urbanization in future. The individual, combined and synergistic impacts of LULC and climate change on water quantity/quality were analyzed by the Soil and Water Assessment Tool(SWAT).Under the 'climate change only' scenario, monthly distribution and projected variation of TSS are expected to follow a pattern similar to streamflow. Nutrients are influenced both by flow and management practices. The variation of Total Nitrogen(TN) and Total Phosphorous(TP) generally follow the flow trend as well. No evident difference in the N:P ratio was projected. Under the 'LULC change only' scenario, TN was projected to decrease,mainly due to the shrinkage of croplands. TP will increase in fall and winter. The N:P ratio shows a strong decreasing potential. Under the 'combined change' scenario, LULC and climate change effect were considered simultaneously. Results indicate that if future loadings are expected to increase/decrease under any individual scenario, then the combined change will intensify that trend. Conversely, if their effects are in opposite directions, an offsetting effect occurs. Science-based management practices are needed to reduce nutrient loadings to the Bay.Ruoyu Wang Latif Kalin 2018Journal of Environmental Sciences2018,30,2:5
6Sulfonate group modified Ni catalyst for highly efficient liquid-phase selective hydrogenation of bio-derived furfural显示文摘The liquid-phase furfural(FAL) hydrogenation to furfuryl alcohol(FOL) and tetrahydrofurfuryl alcohol(THFOL) was investigated using sulfonate group(-SO3 H) grafted activated carbon(AC) supported Ni catalyst, which was prepared and activated simultaneously by liquid phase reduction method. This functionalized nickel catalyst demonstrated an enhanced catalytic performance for selective hydrogenation of FAL, in which almost 100% FOL(<80℃) and THFOL(>100℃) selectivity with complete conversion was obtained, respectively. More importantly, the conversion of transfer hydrogenation of FAL to FOL also can reach almost 100% under optimal conditions(140℃, 4.0 h). The effect of-SO3 H was evaluated and systematically analyzed by the combination of reaction performance and physico-chemical characterizations. Cycling test proved the prepared catalyst could be recycled and reused for several times without noticeably reducing catalytic activity of hydrogenation.Wanbing Gong Chun Chen Haojie Wang Ruoyu Fan Haimin Zhang Guozhong Wang Huijun Zhao 2018Chinese Chemical Letters2018,29,11:4
7Climate change induced eutrophication of cold-water lake in an ecologically fragile nature reserve显示文摘Aquatic ecosystem sustainability around the globe is facing crucial challenges because of increasing anthropogenic and natural disturbances. In this study, the Tianchi Lake, a typical cold-water lake and a UNESCO/MAB(Man and Biosphere) nature reserve located in high latitude and elevation with the relatively low intensity of human activity was chosen as a system to examine the linkages between climate change and eutrophication. As a part of the UNESCO Bogda Man and Biosphere Reserve, Tianchi Lake has been well preserved for prevention from human intervention, but why has it been infected with eutrophication recent years? Our results show that climate change played a significant role in the eutrophication in the Tianchi Lake. Increased temperature, changed precipitation pattern and wind-induced hydrodynamic fluctuations in the summer season were suggested to make a major contribution to the accelerated eutrophication. The results also showed that the local temperature and precipitation changes were closely linked to the large-scale atmospheric circulation, which opens the door for the method to be applied in other regions without local climatic information. This study suggests that there is an urgent need to take into consideration of climate change adaptation into the conservation and management of cold-water lakes globally.Xiaotian Lu Yonglong Lu Deliang Chen Chao Su Shuai Song Tieyu Wang Hanqin Tian Ruoyu Liang Meng Zhang Kifayatullah Khan 2019Journal of Environmental Sciences2019,31,1:4
8Synergistic catalysis of cluster and atomic copper induced by copper-silica interface in transfer-hydrogenation显示文摘To data,using strong metal-support interaction(SMSI)effect to improve the catalytic performance of metal catalysts is an important strategy for heterogeneous catalysis,and this effect is basically achieved by using reducible metal oxides.However,the formation of SMSI between metal and inert-support has been so little coverage and remains challenge.In this work,the SMSI effect can be effectively extended to the inert support-metal catalysis system to fabricate a Cu^(0)/Cu-doped SiO_(2) catalyst with high dispersion and loading(38.5 wt.%)through the interfacial effect of inert silica.In the catalyst,subnanometric composite of Cu cluster and atomic copper(in the configuration of Cu-O-Si)can be consciously formed on the silica interface,and verified by extended X-ray absorption fine structure(EXAFS),in situ X-ray photoelectron spectroscopy(XPS),and high-angle annular dark field-scanning transmission electron microscopy(HAADF-STEM)characterization.The promoting activity in transfer-hydrogenation by the SMSI effect of Cu-silica interface and the synergistic active roles of cluster and atomic Cu have also been revealed from surface interface structure,catalytic activity,and density functional theory(DFT)theoretical calculation at an atomic level.The subnanometric composite of cluster and atomic copper species can be derived from a facile synthesis strategy of metal-inert support SMSI effect and the realistic active site of Cu-based catalyst can also been identified accurately,thus it will help to expand the application of subnanometric materials in industrial catalysis.Ruoyu Fan Yange Zhang Zhi Hu Chun Chen Tongfei Shi Lirong Zheng Haimin Zhang Junfa Zhu Huijun Zhao Guozhong Wang 2021Nano Research2021,14,12:3
9Preparation and characterization of carbonyl iron/strontium hexaferrite magnetorheological fluids显示文摘The heat transfer oil-based magnetorheological fluid(MRF) was prepared using oleic acid-modified micron carbonyl iron powder as a magnetic dispersed phase and strontium hexaferrite(SrFe_(12)O_(19))nanoparticles as an additive.The sedimentation stability of MRFs was studied.The results indicated that the stability of MRFs was improved remarkably by adding SrFe_(12)O_(19) nanoparticles and the sedimentation ratio was only 0.88 in 20 days when the content of nanoparticles reached 10 wt%.The Theological properties were characterized by a HAAKE rheometer without a magnetic field and a capillary rheometer with and without a magnetic field.The effects of SrFe_(12)O_(19) nanoparticles,the temperature,and magnetic field strength were investigated.In addition,the rheological properties could be predicted well using the improved Herschel-Bulkley model,even under a magnetic field.A theoretical model was also proposed to predict the yield stress based on the microstructure of the MRF under an applied magnetic field.Jianrong Liu Xianjun Wang Xia Tang Ruoyu Hong Yaqiong Wang Wenguo Feng 2015Particuology2015,13,5:3
10The key role of CYC2 during meiosis in Tetrahymena thermophila显示文摘Meiotic 再结合为 Spo11 蛋白质做的 DNA 双海滨裂缝(DSB ) 的形成和修理通过一条专业化小径被执行。现在的学习使 cyclin 的功能的角色清楚些, CYC2,在在成熟分裂过程期间有 transcriptionally 高的表达式水平的 Tetrahymena thermophila。与 DSB 的缺席在变化形式开始以后在 2.5-3.5 h 在 meiotic 变化形式过程的拘捕,并且在同伴击倒 CYC2 基因结果,在成熟分裂部门开始前。调查这现象的内在的机制,完全的 transcriptome 侧面在野类型的紧张和 CYC2 猛烈紧张之间被执行。RNA-Seq 结果的功能的分析鉴别相关差别包括 SPO11 表示了基因(DEG ) ,这些 DEG 在 DNA 修理 / 错配修理(MMR ) 被充实在相应再结合(HR ) 称为,它显示 CYC2 能由调整 SPO11 并且参予 HR 在成熟分裂起一个关键作用。Qianlan Xu Ruoyu Wang A.

11Synergistic osteogenic and angiogenic effects of KP and QK peptides incorporated with an injectable and self-healing hydrogel for efficient bone regeneration显示文摘Irregular defects generated by trauma or surgery in orthopaedics practice were usually difficult to be fitted by the preformed traditional bone graft substitute. Therefore, the injectable hydrogels have attracted an increasing interest for bone repair because of their fittability and mini-invasivity. However, the uncontrollable spreading or mechanical failures during its manipulation remain a problem to be solved. Moreover, in order to achieve vascularized bone regeneration, alternatives of osteogenic and angiogenic growth factors should be adopted to avoid the problem of immunogenicity and high cost. In this study, a novel injectable self-healing hydrogel system (GMO hydrogel) loaded with KP and QK peptides had been developed for enhancing vascularized regeneration of small irregular bone defect. The dynamic imine bonds between gelatin methacryloyl and oxidized dextran provided the GMO hydrogel with self-healing and shear-thinning abilities, which led to an excellent injectability and fittability. By photopolymerization of the enclosed GelMA, GMO hydrogel was further strengthened and thus more suitable for bone regeneration. Besides, the osteogenic peptide KP and angiogenic peptide QK were tethered to GMO hydrogel by Schiff base reaction, leading to desired releasing profiles. In vitro, this composite hydrogel could significantly improve the osteogenic differentiation of BMSCs and angiogenesis ability of HUVECs. In vivo, KP and QK in the GMO hydrogel demonstrated a significant synergistic effect in promoting new bone formation in rat calvaria. Overall, the KP and QK loaded GMO hydrogel was injectable and self-healing, which can be served as an efficient approach for vascularized bone regeneration via a minimally invasive approach.Runze Li Chen Zhou Jun Chen Haotian Luo Ruoyu Li Danying Chen Xuenong Zou Weicai Wang 2022Bioactive Materials2022,7,12:2
12Influence of proximity to the Qinghai-Tibet highway and railway on variations of soil heavy metal concentrations and bacterial community diversity on the Tibetan Plateau显示文摘An understanding of soil microbial communities is crucial in roadside soil environmental assessments.The 16S rRNA se quencing of a stressed microbial community in soil adjacent to the Qinghai-Tibet Highway(QTH)revealed that the accu mulation of heavy metals(over about 10 years)has affected the diversity of bacterial abundance and microbial community structure.The proximity of a sampling site to the QTH/Qinghai-Tibet Railway(QTR),which is effectively a measure of the density of human engineering,was the dominant factor influencing bacterial community diversity.The diversity of bacterial communities shows that 16S rRNA gene abundance decreased in relation to proximity to the QTH and QTR in both alpine wetland and meadow areas.The dominant phyla across all samples were Actinobacteria and Proteobacteria.The concentration of Cr and Cd in the soil were positively correlated with proximity to the QTH and QTR(MC/WC sam pling sites),and Ni,Co,and V were positively correlated with proximity to the QTH and QTR(MA/WA sampling sites).The results presented in this study provide an insight into the relationships among heavy metals and soil microbial commu nities,and have important implications for assessing and predicting the impacts of human-induced activities from the QTH and QTR in such an extreme and fragile environment.Xia Zhao JunFeng Wang Yun Wang Xiang Lu ShaoFang Liu YuBao Zhang ZhiHong Guo ZhongKui Xie RuoYu Wang 2019Research in Cold and Arid Regions2019,11,6:2

14Prevalent fecal contamination in drinking water resources and potential health risks in Swat, Pakistan显示文摘Fecal bacteria contaminate water resources and result in associated waterborne diseases.This study assessed drinking water quality and evaluated their potential health risks in Swat, Pakistan. Ground and surface drinking water were randomly collected from upstream to downstream in the River Swat watershed and analyzed for fecal contamination using fecal indicator bacteria(Escherichia coli) and physiochemical parameters(potential of hydrogen, turbidity, temperature, electrical conductivity, total dissolved solid, color, odor and taste). The physiochemical parameters were within their safe limits except in a few locations, whereas, the fecal contaminations in drinking water resources exceeded the drinking water quality standards of Pakistan Environmental Protection Agency(Pak-EPA),2008 and World Health Organization(WHO), 2011. Multivariate and univariate analyses revealed that downstream urbanization trend, minimum distance between water sources and pit latrines/sewerage systems, raw sewage deep well injection and amplified urban,pastures and agricultural runoffs having human and animal excreta were the possible sources of contamination. The questionnaire survey revealed that majority of the local people using 10–20 years old drinking water supply schemes at the rate of 73% well supply,13% hand pump supply, 11% spring supply and 3% river/streams supply, which spreads high prevalence of water borne diseases including hepatitis, intestinal infections and diarrhea, dysentery, cholera, typhoid fever, jaundice and skin diseases in children followed by older and younger adults.Kifayatullah Khan Yonglong Lu Mian Abdal Saeed Hazrat Bilal Hassan Sher Hizbullah Khan Jafar Ali Pei Wang Herman Uwizeyimana Yvette Baninla Qifeng Li Zhaoyang Liu Javed Nawab Yunqiao Zhou Chao Su Ruoyu Liang 2018Journal of Environmental Sciences2018,30,10:1
15pUGTdb:A comprehensive database of plant UDP-dependent glycosyltransferases显示文摘Dear Editor,Plant UDP-dependent glycosyltransferases(UGTs),belonging to the carbohydrate-active enzyme glycosyltransferase 1 family(Louveau and Osbourn,2019),not only play important roles in adaptation to various environments(Cai et al.,2020;Pastorczyk-Szlenkier and Bednarek,2021)but also endow plant natural products with great pharmaceutical and ecological significance(Margolin et al.,2020).In recent years,an increasing number of plant UGTs have been characterized to function in the biosynthesis of many bioactive compounds such as ginsenosides(Wei et al.,2015),breviscapine(Liu et al.,2018),and rubusoside(Xu et al.,2022).Yuqian Liu Qian Wang Xiaonan Liu Jian Chengi Lei Zhang Huanyu Chu Ruoyu Wang Haoran Li Hong Chang Nida Ahmed Zhonghua Wang Xiaoping Liao Huifeng Jiang 2023Molecular Plant2023,16,4:1

18An overview of the switching parameter variation of RRAM显示文摘Resistive random access memory(RRAM) has been considered as one of the most promising candidates for next-generation nonvolatile memory, due to its advantages of simple device structure, excellent scalability, fast operation speed and low power consumption. Deeply understanding the physical mechanism and effectively controlling the statistical variation of switching parameters are the basis of fostering RRAM into commercial application. In this paper, based on the deep understanding on the mechanism of the formation and rupture of conductive filament, we summarize the methods of analyzing and modeling the statistics of switching parameters such as SET/RESET voltage, current, speed or time. Then, we analyze the distributions of switching parameters and the influencing factors. Additionally, we also sum up the analytical model of resistive switching statistics composed of the cell-based percolation model and SET/RESET switching dynamics. The results of the model can successfully explain the experimental distributions of switching parameters of the Ni O- and Hf O2-based RRAM devices. The model also provides theoretical guide on how to improve the uniformity and reliability such as disturb immunity. Finally, some experimental approaches to improve the uniformity of switching parameters are discussed.Meiyun Zhang Shibing Long Guoming Wang Yang Li Xiaoxin Xu Hongtao Liu Ruoyu Liu Ming Wang Congfei Li Pengxiao Sun Haitao Sun Qi Liu Hangbing L Ming Liu 2014Chinese Science Bulletin2014,59,36:1
