7Selective laser melting of NiTi alloy with superior tensile property and shape memory effect显示文摘It is a challenge to develop complex-shaped Ni Ti shape memory alloy parts by traditional processing methods, due to the poor machinability of Ni Ti alloy. It is reported that selective laser melting(SLM) of additive manufacturing could overcome this problem. However, the reported SLM-produced Ni Ti exhibits poor tensile ductility due to the inner defects and adverse unidirectional columnar grains from SLM process. In this work, the defect-less SLM-Ni Ti with nondirective columnar grains was fabricated by optimizing the intraformational laser scanning length and interformational laser scanning direction. The obtained lath-shaped SLM-Ni Ti sample exhibits tensile strain of 15.6%, more than twice of the reported maximum result(7%). Besides, the SLM-Ni Ti part with complex geometry displays a shape memory recovery of 99% under compressive deformation of 50%.Zhiwei Xiong Zhonghan Li Zhen Sun Shijie Hao Ying Yang Meng Li Changhui Song Ping Qiu Lishan Cui 2019Journal of Materials Science & Technology2019,35,10:15
8Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui 2019Biomedical and Environmental Sciences2019,32,1:14

10Long Distance Transmission of SARS-CoV-2 from Contaminated Cold Chain Products to Humans——Qingdao City,Shandong Province,China,September 2020显示文摘Summary What is already known about this topic?Though coronavirus disease 2019(COVID-19)has largely been controlled in China,several outbreaks of COVID-19 have occurred from importation of cases or of suspected virus-contaminated products.Though several outbreaks have been traced to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)isolated on the outer packaging of cold chain products,live virus has not been obtained.Huilai Ma Zhaoguo Wang Xiang Zhao Jun Han Yong Zhang Hong Wang Cao Chen Ji Wang Fachun Jiang Jie Lei Jingdong Song Shaofeng Jiang Shuangli Zhu Huihui Liu Dongyan Wang Yao Meng Naiying Mao Yanhai Wang Zhen Zhu Zhixiao Chen Bingling Wang Qinqin Song Haijun Du Qun Yuan Dong Xia Zhiqiang Xia Peipei Liu Yuchao Wu Zijian Feng Ruqin Gao George F.Gao Wenbo Xu 2021China CDC weekly2021,3,30:13
11OsBRXL4 Regulates Shoot Gravitropism and Rice Tiller Angle through Affecting LAZY1 Nuclear Localization显示文摘Rice tiller angle is a key agronomic trait that contributes to ideal plant architecture and grain production.LAZY1 (LA1) was previously shown to control tiller angle via affecting shoot gravitropism,but the underlying molecular mechanism remains largely unknown.In this study,we identified an LA1-interacting protein named Brevis Radix Like 4 (OsBRXL4).We showed that the interaction between OsBRXL4 and LA1 occurs at the plasma membrane and that their interaction determines nuclear localization of LA1.We found that nuclear localization of LA1 is essential for its function,which is different from AtLA1,its Arabidopsis ortho.log.Overexpression of OsBRXL4 leads to a prostrate growth phenotype,whereas OsBRXLs RNAi plants,in which the expression levels of OsBRXLI,OsBRXL4,and OsBRXL5 were decreased,display a compact phenotype.Further genetic analysis also supported that OsBRXL4 controls rice tiller angle by affecting nuclear localization of LA1.Consistently,we demonstrated that OsBRXL4 regulates the shoot gravitropism through affecting polar auxin transport as did LA1.Taken together,our study not only identifies OsBRXL4 as a regulatory component of rice tiller angle but also provides new insights into genetic regulation of rice plant architecture.Zhen Li Yan Liang Yundong Yuan Lei Wang Xiangbing Meng Guosheng Xiong Jie Zhou Yueyue Cai Ningpei Han Lekai Hua Guifu Liu Jiayang Li Yonghong Wang 2019Molecular Plant2019,12,8:12

13Effect of transcutaneous electrical acupoint stimulation combined with palonosetron on chemotherapy-induced nausea and vomiting: a single.blind,randomized, controlled trial显示文摘Background: Chemotherapy?induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization(TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation(TEAS) on nausea and vomiting after TACE.Methods: A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active?acupuncture(n = 72) or placebo?acupuncture(n Hegu(LI4), Neiguan(P6), an= 70) groups using a covariate?adaptive randomization at a ratio of 1:1. The acupointsd Zusanli(ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory(MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored.Results: Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant(all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active?acupuncture group than in the placebo?acupuncture group and continued to decrease over time with treat?ment(all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active?acupuncture group were slightly lower than those for the placebo?acupuncture group, but the differences were not statistically significant(all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event(P > 0.05).Conclusion: TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy.Jing Xie Lei-Hua Chen Zhou-Yu Ning Chen-Yue Zhang Hao Chen Zhen Chen Zhi-Qiang Meng Xiao-Yan Zhu 2017Chinese Journal of Cancer2017,36,5:11
14Antibacterial Mechanisms of Berberine and Reasons for Little Resistance of Bacteria显示文摘Objective To study the antibacterial mechanisms of berberine and try to understand the reasons why bacteria cells difficultly resisted to it.Methods Detecting the minimal inhibitory concentration(MIC) of bacterial cultures incubated under sub-MIC concentration of berberine,Huanglian,and Neomycin for more than 200 generations,in order to analyze the bacteria resistance.Detecting the binding kinetics of berberine to DNA,RNA,and proteins.Observing the changes in bacterial cell surface structure with scanning electron microscopy.Detecting the Ca2 +and K +released from berberine-treated bacterial cells with atomic absorption spectrum.Detection the absorption of methyl-3H-thymine (3 H-dT),3 H-uridine(3 H-U),and 3 H-tyrosine(3 H-Tyr)into berberine-treated bacterial cells.Results MICs of bacterial cultures,growing more than 200 generations in MH medium with 1/2 MIC of berberine(BA200) or Huanglian(HA200),did not increase compared to the control,while remarkably increased in MH medium with 1/2 MIC of Neomycin (NA200).In addition,from the culture NA200 it was easy to isolate resistant mutant strains which could grow in MH medium with more than four times MIC Neomycin,but from the culture BA200 and HA200 it was difficult to isolate berberine or Huanglian mutant strains could grow in MH medium with more than four times MIC berberine or Huanglian.The binding kinetics of berberine to DNA,RNA,and proteins illustrated that berberine could easily and tightly bind to DNA and RNA,and hardly dis-bind from DNA-and RNA-berberine complexes.Berberine could easily bind to protein too,but also easily dis-bind from berberine-protein complex.The bacterial cells treated with berberine sharply decreased the absorption of 3 H-dT,3 H-U,and 3 H-Tyr,as the radioactive precursors of DNA,RNA,and protein biosynthesis.Berberine could damage bacterial cell surface structure,especially for Gram-negative bacteria.Ca2 +and K + released from berberine-treated cells increased significantly compared to the control.Conclusion All of above results indicate that bacterial cells could not easily become resistant mutants to berberine.The mechanisms for the bactericidal effect of berberine include:inhibiting DNA duplication,RNA transcription,and protein biosynthesis;influencing or inhibiting enzyme activities;destructing the bacterial cell surface structure and resulting in Ca2 +and K +released from cells.All of the berberine bactericidal mechanisms are the most essential physiological functions for a live cell,if influenced any one such function,the mutation would be lethal mutation,so that it is difficult to get berberine resistant cells.The results in this paper also prefigure that berberine and its related Chinese medicines would provide a feasible way to control antibiotic resistance problem.JIN Jian-ling,HUA Guo-qiang,MENG Zhen,GAO Pei-ji State Key Laboratory of Microbial Technology,School of Life Sciences,Shandong University,Jinan 250100,China 2011Chinese Herbal Medicines2011,3,1:11

16Metformin attenuates motility,contraction,and fibrogenic response of hepatic stellate cells in vivo and in vitro by activating AMP-activated protein kinase显示文摘AIM To investigate the effect of metformin on activated hepatic stellate cells(HSCs) and the possible signaling pathways involved. METHODS A fibrotic mouse model was generated by intraperitoneal injection of carbon tetrachloride(CCl_4) and subsequent treatment with or without metformin. The level of fibrosis was detected by hematoxylin-eosin staining, Sirius Red staining, and immunohistochemistry. The HSC cell line LX-2 was used for in vitro studies. The effect of metformin on cell proliferation(CCK8 assay),motility(scratch test and Transwell assay), contraction(collagen gel contraction assay), extracellular matrix(ECM) secretion(Western blot), and angiogenesis(ELISA and tube formation assay) was investigated. We also analyzed the possible signaling pathways involved by Western blot analysis.RESULTS Mice developed marked liver fibrosis after intraperitoneal injection with CCl_4 for 6 wk. Metformin decreased the activation of HSCs, reduced the deposition of ECM, and inhibited angiogenesis in CCl_4-treated mice. Platelet-derived growth factor(PDGF) promoted the fibrogenic response of HSCs in vitro, while metformin inhibited the activation, proliferation, migration, and contraction of HSCs, and reduced the secretion of ECM. Metformin decreased the expression of vascular endothelial growth factor(VEGF) in HSCs through inhibition of hypoxia inducible factor(HIF)-1α in both PDGF-BB treatment and hypoxic conditions, and it down-regulated VEGF secretion by HSCs and inhibited HSC-based angiogenesis in hypoxic conditions in vitro. The inhibitory effects of metformin on activated HSCs were mediated by inhibiting the Akt/mammalian target of rapamycin(m TOR) and extracellular signal-regulated kinase(ERK) pathways via the activation of adenosine monophosphate-activated protein kinase(AMPK).CONCLUSION Metformin attenuates the fibrogenic response of HSCs in vivo and in vitro, and may therefore be useful for the treatment of chronic liver diseases.Zhen Li Qian Ding Li-Ping Ling Ying Wu Dong-Xiao Meng Xiao Li Chun-Qing Zhang 2018World Journal of Gastroenterology2018,24,7:10

18Hydroisomerization performance of platinum supported on ZSM-22/ZSM-23 intergrowth zeolite catalyst显示文摘Hydroisomerization catalysts Pt/ZSM-22,Pt/ZSM-23,and Pt/ZSM-22/ZSM-23 were prepared by supporting Pt on ZSM-22,ZSM-23,and intergrowth zeolite ZSM-22/ZSM-23,respectively.The typical physicochemical properties of these catalysts were characterized by X-Ray Diffraction(XRD),N2 absorption-desorption,Pyridine-Fourier Transform Infrared(Py-FTIR),Transmission Electron Microscopy(TEM),X-Ray Fluorescence(XRF),Scanning Electron Microscopy(SEM) and NH3-Temperature Programmed Desorption(NH3-TPD),and the performance of these catalysts in n-dodecane hydroisomerization was evaluated in a continuous down-flow fixed bed with a stainless steel tubular reactor.The characterization results indicated that the intergrowth zeolite ZSM-22/ZSM-23 possessed the dual structure of ZSM-22 and ZSM-23,and the catalyst Pt/ZSM-22/ZSM-23 had similar pores and weak acidity to Pt/ZSM-22 and Pt/ZSM-23 catalysts.Moreover,Pt/ZSM-22/ZSM-23 catalyst showed a high selectivity in hydroisomerization of long chain n-alkanes to mono-branched isomers.The evaluation results for n-dodecane hydroisomerization indicated that the activity of Pt/ZSM-22/ZSM-23 was the lowest,while the hydroisomerization selectivity was the highest among the three catalysts.The maximum yield of i-dodecane product was 68.3% over Pt/ZSM-22/ZSM-23 at 320 oC.Chi Kebin Zhao Zhen Tian Zhijian Hu Sheng Yan Lijun Li Tianshu Wang Bingchun Meng Xiangbin Gao Shanbin Tan Mingwei Liu Yanfeng 2013Petroleum Science2013,10,2:8
19The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations.Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:7
20Perfluorinated compounds in blood of textile workers and barbers显示文摘12 perfluorinated compounds(PFCs) in human blood from workers in a textile mill in Shandong province and several barbershops in Tianjin were analyzed in this study. It was found that perfluorooctanesulfonate(PFOS) and perfluorooctanoate(PFOA) were the most prominent PFCs, with average concentrations of 5.73 mg/L and 5.46 mg/L for textile workers, and 2.55 mg/L and 2.84 mg/L for barbers.PFOS and perfluorohexanesulfonate(PFHxS) concentrations revealed a positive correlation in blood samples(p < 0.01), and concentrations among PFOS, perfluorononanoic acid(PFNA) and perfluorodecanoic acid(PFDA) also revealed positive correlations(p < 0.01). The influence of gender and age on PFC concentration in blood was also investigated, and the results showed that there was no statistically significant difference between the male and female samples, as well as in samples from people with different ages. Generally speaking, the textile workers may face a higher exposure of PFCs than barbers.Cheng Lu Ya-Li Shi Zhen Zhou Nan-Nan Liu Zhao-Fu Meng Ya-Qi Cai 2014Chinese Chemical Letters2014,25,8:6
