| 1 | Highly active and sintering-resistant heteroepitaxy of Au nanoparticles on ZnO nanowires for CO oxidation显示文摘Gold was supported on commercial ZnO powders(P) and homemade ZnO nanowires(NWs) by a modified deposition–precipitation method. X-ray diffraction and transmission electron microscopy investigation indicated that the size of the Au nanoparticles(NPs) depended strongly on the calcination temperature.The Au NPs were highly dispersed(< 5 nm) on both supports with calcination temperatures < 400 °C.However, after calcination at 600 °C the Au NPs aggregated much more severely on ZnO P than on ZnO NWs. Gold NPs epitaxially grew into the {10–10} facets of the ZnO NWs after calcination at temperatures > 400 °C. Such unique anchoring mechanism accounts for the much better experimentally observed sintering resistance. X-ray photoelectron spectra showed that Au existed as both metallic Au0 and Auδ+species in all the synthesized catalysts with or without calcination treatment; the ratios of Auδ+/Au0,however, varied, depending on the treatment conditions. Catalytic tests showed that the activity for CO oxidation strongly depended on the size of the Au NPs. After calcination at 600 °C, the specific rate for CO oxidation at room temperature decreased about 30 times on Au/ZnO P but only about 4 times on Au/ZnO NW. Stability tests demonstrated that the Au/ZnO NW catalysts had better stability for CO oxidation. | Jiaxin Liu Botao Qiao Yian Song Hailian Tang Yudong Huang Jingyue(Jimmy) Liu | 2016 | Journal of Energy Chemistry2016,25,3: | 2 |
| 2 | A novel pathogenic mutation in FBN2 associated with congenital contractural arachnodactyly for preimplantation genetic diagnosis显示文摘Congenital contractural arachnodactyly(CCA,OMIM:121050),also known as Beals syndrome,belongs to a group of rare autosomal dominant(AD)diseases of connective tissue(Maslen et al.,1997).People with CCA share many distinguishing features,such as arachnodactyly,camp tod actyly,multiple joint contractures(especially finger,elbow,and knee joints),crumpled ears,scoliosis,pectus deformities,and muscular hypoplasia(Jurko et al.,2013).It exhibits no specific geographic or ethnic predilection(Frederic et al.,2009). | Jiaxin Li Yuqian Wang Xiaohui Zhu Yanli Nie Ying Kuo Shuo Guan Jin Huang Ying Lian Yangyu Zhao Rong Li Yuan Wei Jie Qiao Liying Yan | 2020 | Journal of Genetics and Genomics2020,47,5: | 2 |
| 3 | Postoperative infection caused by Acinetobacter baumannii misdiagnosed as a free-living amoeba species in a humeral head hemiarthroplasty patient:a case report显示文摘Background:Acinetobacter baumannii is ubiquitous,facultative intracellular,and opportunistic bacterial pathogen.Its unique abilities allow it to survive in a diverse range of environments,including health care settings,leading to nosocomial infections.And its exceptional ability to develop resistance to multiple antibiotics leaves few drug options for treatment.It has been recognized as a leading cause of nosocomial pneumonia and bacteremia over the world.Case presentation:In this case,a 73-year-old woman presented with a Neer Group VI proximal humeral fracture.Six hours after a successfully performed hemiarthroplasty,she developed continuous fever.Clinical examination revealed that the vitals were regular.Laboratory and radiographic examinations revealed only elevated procalcitonin levels.Blood culture revealed no bacterial or fungal growth.Cooling treatment and empirical broad-spectrum antibiotic therapy showed no apparent effect.Conclusions:We report a postoperative infection caused by Acinetobacter baumannii.The infectious pathogen was identified via molecular DNA sequencing and was initially misidentified as a free-living amoeba species upon microscopic examinations.The patient was mistreated with antiamebic combination therapy.Her symptoms persisted for over 4 months and were eventually followed by her death. | Jiaxin Tang Huaimin Zhu Li Cai Tingting Tang Jian Tang Yuehua Sun Ming Liu Kerong Dai Zhiguang Qiao Chao Yu | 2018 | Infectious Diseases of Poverty2018,7,1: | 1 |
| 4 | 肝肠循环因子FGF15/19调节胆汁酸代谢从而控制肝脏尺寸大小与肝癌发生显示文摘文章简介肝脏是人体的一个重要代谢器官,它的大小相对于整个个体大小始终维持在一个合适的比例。肝脏如何感知生长起始和停止是肝脏发育、再生以及癌症生物学中一个有待解决的基本科学问题。近年来研究发现,Hippo信号通路在从果蝇到哺乳动物个体的器官发育及大小调控中都起着至关重要的作用。然而具体何种外部因子在调控Hippo信号通路来维持肝脏大小稳态及抑制癌症发生,一直是领域内未解决的问题。 | 姬素渊 刘清许 张世浩 陈青花 王聪 Weiji Zhang Chen Xiao Yuxi Li Cheng Nian Jiaxin Li Junhong Li Jing Geng Lixin Hong Changchuan Xie Ying He Xing Chen Xun Li Zhen-Yu Yin Han You Kwang-Huei Lin Qiao Wu Chundong Yu Randy L.Johnson Li Wang Lanfen Chen Fen Wang 周大旺 | 2020 | 科学新闻2020,,2: | 1 |
| 5 | Effects of Bacillus subtilis and Saccharomyces cerevisiae inoculation on soil bacterial community and rice yield under combined irrigation with reclaimed and fresh water显示文摘In order to save fresh water and reduce soil salt accumulation,reclaimed water-fresh water combined irrigation,i.e,irrigation with reclaimed water for 50 d and then with fresh water till harvest,was used in rice planting.Bacillus subtilis and Saccharomyces cerevisiae were inoculated into the soil at the end of reclaimed water irrigation.The inoculation weight per pot of these microorganisms was as follows:0 g and 0 g(J0),5 g and 0 g(J1),3.75 g and 1.25 g(J2),2.5 g and 2.5 g(J3),1.25 g and 3.75 g(J4),and 0 g and 5 g(J5),respectively.Treatment using reclaimed water in the whole stage was used as the control(CK).The plant height,tiller,physical and chemical properties of the soil,and soil bacterial diversity were measured.It was found that the plant height of rice was increased significantly by J1-J5 treatments.The dry weight of rice root,stem,and panicle and the 1000-grain weight increased significantly,while the leaf dry weight decreased.Microorganism inoculation significantly increased the nutrient absorption capacity of the crops.J1,J2,and J4 treatments significantly increased the amount of nitrate-nitrogen,ammonium nitrogen,available phosphorus,and available potassium,while J3,J4,and J5 treatments increased the soil organic matter,and microbial inoculation significantly decreased the EC of soil.J4 treatment induced the largest reduction in EC,and microorganisms treatments increased soil pH.Bacterial function prediction based on the KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway indicated that soil metabolic function was not significantly disturbed by the treatments.Organic matter and pH are the two main factors affecting the structure of the bacterial community in soil.3.75 g of B.subtilis and 1.25 g of S.cerevisiae per pot is the best inoculation ratio. | Hongfei Lu Xuebin Qi Ping Li Dongmei Qiao Shafeeq-ur-Rahman Fangfang Bai Jiaxin Cui | 2022 | International Journal of Agricultural and Biological Engineering2022,15,3: | 0 |
| 6 | RASGRP1 targeted by H3K27me3 regulates myoblast proliferation and differentiation in mice and pigs显示文摘Skeletal muscle is not only the largest organ in the body that is responsible for locomotion and exercise but also crucial for maintaining the body’s energy metabolism and endocrine secretion.The trimethylation of histone H3 lysine 27(H3K27me3)is one of the most important histone modifications that participates in muscle development regulation by repressing the transcription of genes.Previous studies indicate that the RASGRP1 gene is regulated by H3K27me3 in embryonic muscle development in pigs,but its function and regulatory role in myogenesis are still unclear.In this study,we verify the crucial role of H3K27me3 in RASGRP1 regulation.The gain/loss function of RASGRP1 in myogenesis regulation is performed using mouse myoblast C2C12 cells and primarily isolated porcine skeletal muscle satellite cells(PSCs).The results of qPCR,western blot analysis,EdU staining,CCK-8 assay and immunofluorescence staining show that overexpression ofRASGRP1 promotes cell proliferation and differentiation in both skeletal muscle cell models,while knockdown of RASGRP1 leads to the opposite results.These findings indicate that RASGRP1 plays an important regulatory role in myogenesis in both mice and pigs. | Liyao Xiao Jiaxin Qiao Yiyang Huang Baohua Tan Linjun Hong Zicong Li Gengyuan Cai Zhenfang Wu Enqin Zheng Shanshan Wang Ting Gu | 2024 | Acta Biochimica et Biophysica Sinica2024,56,3: | 0 |
