| 1 | Mass transfer in gas–liquid stirred reactor with various triple-impeller combinations显示文摘The gassed power demand and volumetric mass transfer coefficient(kLa) were investigated in a fully baffled,dished-base stirred vessel with a diameter of 0.30 m agitated by five triple-impeller combinations. Six types of impellers(six-half-elliptical-blade disk turbine(HEDT), four-wide-blade hydrofoil impeller(WH) pumping down(D) and pumping up(U), parabolic-blade disk turbine(PDT), and CBY narrow blade(N) and wide blade(W)) were used to form five combinations identified by PDT + 2CBYN, PDT + 2CBYW, PDT + 2WHD,HEDT + 2WHDand HEDT + 2WHU, respectively. The results show that the relative power demand of HEDT + 2WHUis higher than that of other four impeller combinations under all operating conditions. At low superficial gas velocity(uG), kLa differences among impeller combinations are not obvious. However,when uG is high, PDT + 2WHDshows the best mass transfer performance and HEDT + 2WHUshows the worst mass transfer performance under all operating conditions. At high uGand a given power input, the impeller combinations with high agitation speed and big projection cross-sectional area lead to relatively high values of kLa. Based on the experimental data, the regressed correlations of gassed power number with Froude number and gas flow number, and kLa with power consumption and superficial gas velocity are obtained for five different impeller combinations, which could be used as guidance for industrial design. | Jinjin Zhang Zhengming Gao Yating Cai Ziqi Cai Jie Yang Yuyun Bao | 2016 | Chinese Journal of Chemical Engineering2016,24,6: | 5 |
| 2 | Effects of different amino acid levels and a carvacrol-thymol blend on growth performance and intestinal health of weaned pigs显示文摘Background:Over the past years,antibiotic growth promoter had been restricted in animal husbandry production in many countries because of antimicrobial resistance and foodborne antibiotic residues.However,the problems of poor intestinal health and low growth efficiency of piglets have not been solved completely in an antibiotic-free diet,and it is urgent to explore alternatives to antimicrobial growth promoters.Methods:Here,a total of 532 weaned pigs were assigned to one of 4 treatments,the low amino acid(AA)level diet(d 1 to d 14 is 1.35%,d 15 to d 42 is 1.25%)(Low AA),the low AA level diet supplementation with a carvacrol-thymol blend(50 mg carvacrol and 50 mg thymol/kg of diet)(CB)(Low AA+CB),the high AA level diet(d 1 to d 14 is 1.50%,d 15 to d 42 is 1.40%)(High AA),and the high AA level diet supplementation with a CB(High AA+CB),respectively.Then we measured growth performance and intestinal health indicators of weaned pigs.Results:Results showed that high AA level significantly reduced plasma urea nitrogen,plasma Interleukin-6(IL-6)and fecal lipocalin-2 contents(P<0.05),significantly increased the relative abundance of fecal Lactobacillus and Enterococcus,and had a trend to increase the fecal secretory immunoglobulin A(sIgA)and mucin 2(MUC 2)contents(P<0.05)in piglets,thereby alleviating the diarrhea of piglets and reducing the feed conversion ratio(FCR)of piglets during d 1~14 after weaning.Dietary supplementation with CB significantly increased the activity of plasma antioxidant enzymes T-SOD and GSH-px(P<0.05),while significantly reduced plasma malondialdehyde(MDA),plasma interleukin-1β(IL-1β),plasma endotoxin and D-lactic acid contents(P<0.05).Meanwhile,CB significantly decreased fecal lipocalin-2 contents and the abundance of fecal Escherichia coli(P<0.05).Thus,we hypothesis that dietary supplementation with CB significantly increased the average daily gain(ADG)of piglets(P<0.05)during d 1~14 after weaning through promoting intestinal health.Conclusion:These results suggest that high AA level and dietary supplementation with CB improved the growth performance of weaned pigs in an antibiotic-free diet by improving AA metabolism and intestinal antioxidant capacity. | Yanan Wang Zhipeng Yang Yuanfei Zhou Jiajian Tan Haiqing Sun Defa Sun Yuyun Mu Jian Peng Hongkui Wei | 2022 | Journal of Animal Science and Biotechnology2022,13,5: | 2 |
| 3 | Defect passivation by nontoxic biomaterial yields 21% efficiency perovskite solar cells显示文摘Defect passivation is one of the most important strategies to boost both the efficiency and stability of perovskite solar cells(PSCs).Here,nontoxic and sustainable forest-based biomaterial,betulin,is first introduced into perovskites.The experiments and calculations reveal that betulin can effectively passivate the uncoordinated lead ions in perovskites via sharing the lone pair electrons of hydroxyl group,promoting charge transport.As a result,the power conversion efficiencies of the p-i-n planar PSCs remarkably increase from 19.14%to 21.15%,with the improvement of other parameters.The hydrogen bonds of betulin lock methylamine and halogen ions along the grain boundaries and on the film surface and thus suppress ion migration,further stabilizing perovskite crystal structures.These positive effects enable the PSCs to maintain 90%of the initial efficiency after 30 days in ambient air with 60%±5%relative humidity,75%after 300 h aging at 85℃,and 55%after 250 h light soaking,respectively.This work opens a new pathway for using nontoxic and low-cost biomaterials from forest to make highly efficient and stable PSCs. | Shaobing Xiong Tianyu Hao Yuyun Sun Jianming Yang Ruru Ma Jiulong Wang Shijing Gong Xianjie Liu Liming Ding Mats Fahlman Qinye Bao | 2021 | Journal of Energy Chemistry2021,30,4: | 2 |

| 7 | Inhibition of immune checkpoints prevents injury-induced heterotopic ossification显示文摘Heterotopic ossification(HO),true bone formation in soft tissue,is closely associated with abnormal injury/immune responses.We hypothesized that a key underlying mechanism of HO might be injury-induced dysregulation of immune checkpoint proteins(ICs).We found that the earliest stages of HO are characterized by enhanced infiltration of polarized macrophages into sites of minor injuries in an animal model of HO.The non-specific immune suppressants,Rapamycin and Ebselen,prevented HO providing evidence of the central role of the immune responses.We examined the expression pattern of ICs and found that they are dysregulated in HO lesions.More importantly,loss of function of inhibitory ICs(including PD1,PD-L1,and CD152)markedly inhibited HO,whereas loss of function of stimulatory ICs(including CD40L and OX-40L)facilitated HO.These findings suggest that IC inhibitors may provide a therapeutic approach to prevent or limit the extent of HO. | Chen Kan Jiazhao Yang Ding Na Yuanhong Xu Baixia Yang Haodong Zhao Huadong Lu Yuyun Li Keqin Zhang Tammy LMcGuire John AKessler Lixin Kan | 2019 | Bone Research2019,7,4: | 1 |

| 13 | Optimization of synergistic energy storage density and efficiency for eco-friendly (Na_(0.5)Bi_(0.5))_(0.6)Sr_(0.4)TiO_(3)-based relaxor ferroelectric ceramics显示文摘Inspired by increasing demand of advanced pulsed power capacitors,the development of lead-free dielectric ceramic capacitors with high energy storage density and temperature-insensitive performance are extremely crucial.Herein,the lead-free relaxor ferroelectric ceramics based on(1-x)(Na_(0.5)Bi_(0.5))0.6Sr_(0.4)TiO_(3-x)Sr_(0.7)La_(0.2)ZrO_(3)[abbreviated as(1-x)NBST-xSLZ]are prepared by the solid-state reaction route.The large recoverable energy density(Wrec)of 3.45 J/cm^(3) and efficiency(h)of 90.1%are simultaneously realized in 0.86NBST-0.14SLZ ceramic due to increased breakdown strength.Furthermore,both the Wrec and h of 0.86NBST-0.14SLZ ceramic display superior of thermal stability(20e180C),frequency stability(1e1000 Hz),and cycle stability(10^(4))within a satisfactory range of variation.In addition,the 0.86NBST-0.14SLZ ceramic can also achieve a large current density(CD)of 625 A/cm^(2),an ultrahigh power density(PD)of 50 MW/cm^(3) and a fast discharge rate(t0.90)of 160.8 ns at 160 kV/cm.These results demonstrate that the 0.86NBST-0.14SLZ ceramic could be a highly competitive and ecofriendly relaxor ferroelectric material for next-generation pulsed power capacitors. | Hu Di Pan Zhongbin Wu Lukang Yang Fan Tang Luomeng Zhao Jinghao Shen Yihao Chen Yuyun Li Peng Zhai Jiwei Liu Jinjun | 2021 | Journal of Materiomics2021,7,4: | 0 |
| 14 | DNA damage-mediated cellular senescence promotes hand-foot syndrome that can be relieved by thymidine prodrug显示文摘Hand-foot syndrome(HFS)is a widely recognized dose-limiting cutaneous toxicity effect of fluoropyrimidine chemotherapy agents that impairs clinical benefits and treatment outcomes.Even though the cause and pathophysiology of HFS are relatively widely reported,how the toxicity of fluoropyrimidine translates into persistent inflammation has not been studied.Additionally,prevention and treatment strategies for HFS based on its mechanistic occurrence and development are scarce.In our study,we demonstrated that cGAS-STING signaling pathway-mediated cellular senescence played a critical role in the inflammatory reaction and provided a therapeutic solution for HFS.Mechanistically,DNA damage,as the primary cytotoxic cause,in keratinocytes induces cell cycle arrest,activates the cGAS-STING signaling pathway,and subsequently mediates cellular senescence,ultimately fueling a robust secondary inflammatory response that results in HFS.More importantly,the thymidine prodrug thymidine diacetate was proven to be effective in preventing HFS by compensating for thymidylate deficiency to facilitate the replication and repair of DNA and thus causing the escape from cellular senescence.These data highlight the importance of DNA damage-mediated cellular senescence in the etiology of HFS and provide a potential therapeutic anchor point for fluoropyrimidine-induced HFS. | Bingxue Yang Xinran Xie Zhaoyu Wu Dazhao Lv Jiajun Hu Yuyun Chen Jiaxing Li Shuyue Luo Jiacheng Li Jie Luo Shiyi Zhang | 2023 | Genes & Diseases2023,10,6: | 0 |
| 15 | Dissection of the genetic mechanisms underlying congenital anal atresia in pigs显示文摘Anal atresia is an innate disorder in the development of the distal hindgut in infants,which is caused by the failure of anal cloacal membrane to rupture due to the dysplasia of posterior intestine(Cuschieri,2001).The disorder shows a prevalence of0.03%-0.05%,of which patients with a family history account for 1%-9%of cases(Wood and Levitt,2018). | Kai Jiang Yuyun Xing Pan Xu Qiang Yang Chuanmin Qiao Weiwei Liu Hao Chen Yuyong He Jun Ren Lusheng Huang | 2020 | Journal of Genetics and Genomics2020,47,5: | 0 |
| 16 | Influences of uncertainties to the generation feasible region for medium- and long-term electricity transaction显示文摘For the implementation of power market in China,medium-and Iong-term security checks are essential for bilateral transactions,of which the electricity quantity that constitutes the generation feasible region(GFR)is the target.However,uncertainties from load forecasting errors and transmission contingencies are threats to medium-and Iong-term electricity tradi ng in terms of their in flue nces on the GFR.In this paper,we prese nt a graphic distortio n pattern in a typical threegenerator system using the Monte Carlo method and projection theory based on security constrained economic dispatch.The underlying potential risk to GFR from uncertainties is clearly visualized,and their impact characteristics are discussed.A case study on detailed GFR distortion was included to dem on strate the effectiveness of this visualization model.The result implies that a small uncertainty could distort the GFR to a remarkable extent and that different line-contingency precipitates disparate the GFR distortion patterns,thereby eliciting great emphasis on load forecasting and line reliability in electricity transacti ons. | Yuyun Yang Zhenfei Tan Zhilin Jiang Jun Yao Xingqiang Wang Mingyuan Wang Yan Xie Zhiyun Hu | 2020 | Global Energy Interconnection2020,3,6: | 0 |
| 17 | Transcriptional landscapes of de novo root regeneration from detached Arabidopsis leaves revealed by time-lapse and single-cell RNA sequencing analyses显示文摘Detached Arabidopsis thaliana leaves can regenerate adventitious roots,providing a platformfor studying de novo root regeneration(DNRR).However,the comprehensive transcriptional framework of DNRR remains elusive.Here,we provide a high-resolution landscape of transcriptome reprogramming from wound response to root organogenesis in DNRR and show key factors involved in DNRR.Time-lapse RNA sequencing(RNA-seq)of the entire leaf within 12 h of leaf detachment revealed rapid activation of jasmonate,ethylene,and reactive oxygen species(ROS)pathways in response towounding.Genetic analyses confirmed that ethylene andROSmay serve as wound signals to promoteDNRR.Next,time-lapse RNA-seq within 5 d of leaf detachment revealed the activation of genes involved in organogenesis,wound-induced regeneration,and resource allocation in the wounded region of detached leaves during adventitious rooting.Genetic studies showed that BLADE-ON-PETIOLE1/2,which control aboveground organs,PLETHORA3/5/7,which control root organogenesis,and ETHYLENE RESPONSE FACTOR115,which controlswound-induced regeneration,are involved in DNRR.Furthermore,single-cell RNA-seq data revealed gene expression patterns in thewounded region of detached leaves during adventitious rooting.Overall,our study not only provides transcriptome tools but also reveals key factors involved in DNRR from detached Arabidopsis leaves. | Wu Liu Yuyun Zhang Xing Fang Sorrel Tran Ning Zhai Zhengfei Yang Fu Guo Lyuqin Chen Jie Yu Madalene SIson Teng Zhang Lijun Sun Hongwu Bian Yijing Zhang Li Yang Lin Xu | 2022 | Plant Communications2022,3,4: | 0 |
