1Pt/CNT纳米催化剂的微波快速合成及其对甲醇电化学氧化的电催化性能显示文摘As a rapid uniform and efficient heating method, microwave irradiation has been widely used in chemical reaction and preparing nanomaterials. Here Pt/carbon nanotube(CNT) catalysts with w(Pt)=18.1% and 9.4 % were rapidly synthesized by microwave irradiation heating polyol process and employing the ethylene glycol solution of H 2PtCl 6 as the precursors in the presence of CNT support. TEM imaging showed that microwave-prepared Pt nanoparticles were very uniform in size, with an average size of 3.1 nm, and uniformly dispersed on the CNT surface. Electrochemical experiments demonstrated that microwave-synthesized Pt/CNT catalysts exhibited a higher catalytic activity for electrooxidation of liquid methanol than E-TEK Pt/C. The significant improvement in catalyst performance derives from that microwave-synthesized Pt nanoparticles have a uniform small particle size and uniforml dispersion on the CNT surface.陈卫祥 韩贵 LEE Jim Yang 刘昭林 2003高等学校化学学报2003,24,12:31

3Cancer metabolic reprogramming: importance, main features, and potentials for precise targeted anti-cancer therapies显示文摘Cancer cells are well documented to rewire their metabolism and energy production networks to support and enable rapid proliferation, continuous growth, survival in harsh conditions, invasion, metastasis, and resistance to cancer treatments. Since Dr. Otto Warburg's discovery about altered cancer cell metabolism in 1930, thousands of studies have shed light on various aspects of cancer metabolism with a common goal to find new ways for effectively eliminating tumor cells by targeting their energy metabolism. This review highlights the importance of the main features of cancer metabolism, summarizes recent remarkable advances in this field, and points out the potentials to translate these scientific findings into life-saving diagnosis and therapies to help cancer patients.Liem Minh Phan Sai-Ching Jim Yeung Mong-Hong Lee 2014Cancer Biology & Medicine2014,11,1:11
4西双版纳热带森林挥发性有机物的观测研究显示文摘2002年7月中旬利用异戊二烯通量测定系统对云南西双版纳热带森林异戊二烯的排放通量进行了连续测量,同时对光合有效辐射(PAR)、气温、湿度、风等参数进行了观测.结果表明,热带地区人工橡胶林区域湿季异戊二烯的排放有明显的日变化规律,中午前后为一天中的最大值,异戊二烯排放通量的日平均值在0.85~0.24mgC/(m2(h)之间.对小时值和日平均值而言,异戊二烯的排放与PAR和气温的变化规律比较一致,但它对PAR比对气温更加敏感.不同的天气状况对异戊二烯的排放有非常明显的影响.橡胶林是一个单萜烯排放者,其单萜烯的排放速率明显依赖于PAR.橡胶林和热带雨林冠层上空异戊二烯和单萜烯的浓度也有明显的日变化规律,而且橡胶林区域的异戊二烯和单萜烯的浓度均明显高于热带雨林.白建辉 Bradly Baker Curtis Johnson 李庆军 王永峰 赵崇奖 Lee Klinger Alex Guenther Jim Greenberg 2004中国环境科学2004,24,2:9
5多器官床旁即时超声在新型冠状病毒肺炎中的应用:国际专家共识显示文摘新型冠状病毒肺炎(简称新冠肺炎,COVID-19)自首次报道以来,已造成全球超一亿人感染,给各国的公共卫生体系造成了巨大威胁。新冠肺炎的临床表现以呼吸系统体征和症状为主,80%的患者症状轻微,约5%为危重症患者,常表现为急性呼吸窘迫综合征(ARDS)。前期,由于缺乏相关研究,面对日益紧迫的临床困境,医务人员不得不借鉴采取一些经验性措施以应对疫情。王臻(译) Arif Hussain Gabriele Via Lawrence Melniker Alberto Goffi Guido Tavazzi Luca Neri Tomas Villen Richard Hoppmann Francesco Mojoli Vicki Noble Laurent Zieleskiewicz Pablo Blanco Irene W.Y.Ma Mahathar Abd.Wahab Abdulmohsen Alsaawi Majid AI Salamah Martin Balik Diego Barca Karim Bendjelid Belaid Bouhemad Pablo Bravo-Figueroa Raoul Breitkreutz Juan Calderon Jim Connolly Roberto Copetti Francesco Corradi Anthony J.Dean AndréDenault Deepak Govil Carmela Graci Young-Rock Ha Laura Hurtado Toru Kameda Michael Lanspa Christian B Laursen Francis Lee Rachel Liu Massimiliano Meineri Miguel Montorfano Peiman Nazerian Bret P.Nelson Aleksandar N.Neskovic Ramon Nogue Adi Osman JoséPazeli Elmo Pereira-Junior Tomislav Petrovic Emanuele Pivetta Jan Poelaert Susanna Price Gregor Prosen Shalim Rodriguez Philippe Rola Colin Royse Yale Tung Chen Mike Wells Adrian Wong Wang Xiaoting Wang Zhen Yaseen Arabi 2021中国呼吸与危重监护杂志2021,20,2:5
6Impact of diabetes on promoting the growth of breast cancer显示文摘Background:Type Ⅱ diabetes mellitus(DM2)is a significant risk factor for cancers,including breast cancer.However,a proper diabetic breast cancer mouse model is notwell-established for treatment strategy design.Additionally,the precise diabetic signaling pathways that regulate cancer growth remain unresolved.In the present study,we established a suitable mouse model and demonstrated the pathogenic role of diabetes on breast cancer progression.Methods:We successfully generated a transgenic mouse model of human epidermal growth factor receptor 2 positive(Her2^(+) or ERBB2)breast cancer with DM2 by crossing leptin receptor mutant(Lepr^(db/+))mice with (MMTV-ErbB2/neu)mice.Themousemodelswere administrated with antidiabetic drugs to assess the impacts of controlling DM2 in affecting tumor growth.Magnetic resonance spectroscopic imaging was employed to analyze the tumor metabolism.Results:Treatment with metformin/rosiglitazone in MMTV-ErbB2/Lepr^(db/db) mousemodel reduced serum insulin levels,prolonged overall survival,decreased cumulative tumor incidence,and inhibited tumor progression.Anti-insulin resistance medications also inhibited glycolytic metabolism in tumors in vivo as indicated by the reduced metabolic flux of hyperpolarized ^(13)C pyruvate-to-lactate reaction.The tumor cells from MMTV-ErbB2/Lepr^(db/db) transgenic mice treated with metformin had reprogrammed metabolism by reducing levels of both oxygen consumption and lactate production.Metformin decreased the expression of Myc and pyruvate kinase isozyme 2(PKM2),leading to metabolism reprogramming.Moreover,metformin attenuated the mTOR/AKT signaling pathway and altered adipokine profiles.Conclusions:MMTV-ErbB2/Lepr^(db/db) mouse model was able to recapitulate diabetic HER2^(+) human breast cancer.Additionally,our results defined the signaling pathways deregulated in HER2^(+) breast cancer under diabetic condition,which can be intervened by anti-insulin resistance therapy.Ping-Chieh Chou Hyun Ho Choi Yizhi Huang Enrique Fuentes-Mattei Guermarie Velazquez-Torres Fanmao Zhang Liem Phan Jaehyuk Lee Yanxia Shi James A.Bankson Yun Wu Huamin Wang Ruiying Zhao Sai-Ching Jim Yeung Mong-Hong Lee 2021Cancer Communications2021,41,5:4
7经自然腔道取标本手术(NOSES)治疗结直肠癌的国际共识显示文摘近年来,经自然腔道取标本手术(NOSES)治疗结直肠癌已引起了广泛关注。NOSES应用于结直肠手术的潜在优势包括减轻术后疼痛,减少伤口并发症,减少对术后镇痛的需求,加快肠道功能的恢复,缩短住院时间,更好的美容效果,以及给患者带来了更佳的心理状态。尽管NOSES的手术创伤显著减轻,然而该技术也存在一些潜在问题。尤其随着这项新技术的兴起,人们对其无菌的把控、肿瘤学结果和病例选择等问题表示出关切。因此,迫切需要一部操作指南来规范NOSES手术在结直肠癌中的开展。经过国际NOSES联盟全体成员的三轮讨论,最终形成了该部共识。这一共识有助于NOSES在全球范围内的长远发展。Xu Guan Zheng Liu Antonio Longo Jian-Chun Cai William Tzu-Liang Chen Lu-Chuan Chen Ho-Kyung Chun Joaquim Manuel da Costa Pereira Sergey Efetov Ricardo Escalante Qing-Si He Jun-Hong Hu Cuneyt Kayaalp Seon-Hahn Kim Jim S.Khan Li-Jen Kuo Atsushi Nishimura Fernanda Nogueira Junji Okuda Avanish Saklani Ali A.Shafik Ming-Yin Shen Jung-Tack Son Jun-Min Song Dong-Hui Sun Keisuke Uehara Gui-Yu Wang Ye Wei Zhi-Guo Xiong Hong-Liang Yao Gang Yu Shao-Jun Yu Hai-Tao Zhou Suk-Hwan Lee Petr V.Tsarkov Chuan-Gang Fu Xi-Shan Wang The International Alliance of NOSES 2019Gastroenterology Report2019,7,1:3

9An integrated approach to improve the performance of lean–electrolyte lithium–sulfur batteries显示文摘While the sulfur conversion reaction kinetics in Li–S batteries is nowadays improved by the use of appropriate electrocatalysts,it remains a challenge for the batteries to perform well under the lean electrolyte condition where polysulfide shuttle,electrode passivation and the loss of electrolyte due to side reactions,are aggravated.These challenges are addressed in this study by the tandem use of a polysulfide conversion catalyst and a redox–targeting mediator in a gel sulfur cathode.Specifically,the gel cathode reduces the polysulfide mobility and hence the polysulfide shuttle and the passivation of the lithium anode by the crossover polysulfides.The redox mediator restrains the deposition of inactive sulfur species in the cathode thereby enabling the Fe–N and Co–N co–doped carbon catalyst to prolong its catalytic activity.Consequently,the integrated catalytic system is able to increase the discharge capacity of high–loading (6.8 mg cm^(-2)) lean–electrolyte (4.0μL mg^(-1)) Li–S batteries from~630 to~1316 m Ah g^(-1),concurrently with an improvement of the cycle life (600 cycles with 46%capacity retention at 1.0 m A cm^(-2)).Redox mediator assisted catalysis in a gel cathode is therefore an effective strategy to extend the application of the sulfur conversion catalyst in lean electrolyte Li–S batteries.Hualin Ye Jianguo Sun Yun Zhao Jim Yang Lee 2022Journal of Energy Chemistry2022,31,4:2
