| 3 | Endophytic bacteria in grass crop growth promotion and biostimulation显示文摘Plants naturally carry microbes on seeds and within seeds that may facilitate development and early survival of seedlings.Some crops have lost seed-vectored microbes in the process of domestication or during seed storage and seed treatment.Biostimulant microbes from wild plants were used by pre-modern cultures to re-acquire beneficial seed microbes.Today some companies have developed or are developing the use of microbes obtained from soils or plant sources to stimulate plant development and growth.Many of these biostimulant microbes are endophytic in plants.Biostimulant products also include humic substances,which appear to function as signal molecules in plants,triggering increased internalization of soil microbes into root cells and tissues.In addition,protein coatings on seeds fuel the growth of seed surface-vectored microbes,increasing microbial activity around and within roots.In this article,we provide evidence of the endophytic nature of many biostimulant microbes,and suggest that many of the beneficial effects of microbial biostimulants stem from their action as endophytes or as participants or stimulants of rhizophagy cycle activity. | James F.White Xiaoqian Chang Kathryn L.Kingsley Qiuwei Zhang Peerapol Chiaranunt April Micci Fernando Velazquez Matthew Elmore Sharron Crane Shanjia Li Jiaxin Lu María Carmen Molina Natalia González-Benítez Miguel J.Beltrán-García Kurt P.Kowalski | 2021 | Grass Research2021，1，1： | 0 |
| 4 | BEA沸石后合成金属(Sn,Zr,Hf)改性:结合Lewis和Bronsted酸性进行级联催化显示文摘Sn,Zr和Hf等Lewis酸性金属中心改性的沸石是许多生物炼制相关反应(如碳水化合物异构化和呋喃Meerwein-Pondorf-Verley(MPV)还原)中有应用前景的催化剂.在大孔BEA沸石框架中固载上述金属离子得到的催化剂性能良好.然而,制备该类催化剂通常需采用昂贵的有机金属前体,并且需要经历多步制备过程.本文开发了一种简易的固态研磨法,采用简单的无机金属前体,在脱铝BEA沸石中成功掺入了高度分散的、高金属含量(Si/M比为50-75)的孤立Sn,Zr和Hf.在样品焙烧前,采用甲醇处理去除过量的金属,可使孤立金属位点高含量、有效地掺杂在BEA框架中.在改性的BEA沸石中,Lewis酸位点来自于开放的Sn,Zr和Hf孤立金属离子位点;Sn改性的BEA上Lewis酸位点还包括封闭的Sn位点,但开放的Sn位点表现出最高的Lewis酸性.Br?nsted酸性来自于受开放金属位点Lewis酸性金属离子摄动的硅羟基以及与开放金属位点相连的羟基.Sn,Zr,Hf改性的BEA沸石在肉桂醛级联还原醚化反应中表现出较好的催化活性.以异丙醇为溶剂,肉桂醛先在Lewis酸位点上发生MPV还原生成肉桂醇;随后,肉桂醇在Br?nsted酸位点发生醚化反应生成肉桂基丙基醚.其中,Sn改性的BEA沸石表现出最高的催化活性,这是因为其具有最强的Lewis酸性,这对第一步MPV反应至关重要.此外,将本研究中Sn改性优化固态离子交换法用于对不同形貌BEA沸石进行改性以提高其催化性能,结果表明,BEA沸石多级孔结构进一步有利于级联还原醚化反应. | Peerapol Pornsetmetakul Ferdy J.A.G.Coumans Rim C.J.van de Poll Anna Liutkova Duangkamon Suttipat Brahim Mezari Chularat Wattanakit Emiel J.M.Hensen | 2023 | Chinese Journal of Catalysis2023，55，12： | 0 |
| 5 | Gastrostomy tubes: Fundamentals, periprocedural considerations, and best practices显示文摘Gastrostomy tube placement is a procedure that achieves enteral access for nutrition,decompression,and medication administration.Preprocedural evaluation and selection of patients is necessary to provide optimal benefit and reduce the risk of adverse events(AEs).Appropriate indications,contraindications,ethical considerations,and comorbidities of patients referred for gastrostomy placement should be weighed and balanced.Additionally,endoscopist should consider either a transoral or transabdominal approach is appropriate,and radiologic or surgical gastrostomy tube placement is needed.However,medical history,physical examination,and imaging prior to the procedure should be considered to tailor the appropriate approach and reduce the risk of AEs. | Anand Rajan Peerapol Wangrattanapranee Jonathan Kessler Trilokesh Dey Kidambi James H Tabibian | 2022 | World Journal of Gastrointestinal Surgery2022，14，4： | 0 |
