1The joint automated repository for various integrated simulations (JARVIS) for data-driven materials design显示文摘The Joint Automated Repository for Various Integrated Simulations(JARVIS)is an integrated infrastructure to accelerate materials discovery and design using density functional theory(DFT),classical force-fields(FF),and machine learning(ML)techniques.JARVIS is motivated by the Materials Genome Initiative(MGI)principles of developing open-access databases and tools to reduce the cost and development time of materials discovery,optimization,and deployment.Kamal Choudhary Kevin F.Garrity Andrew C.E.Reid Brian DeCost Adam J.Biacchi Angela R.Hight Walker Zachary Trautt Jason Hattrick-Simpers A.Gilad Kusne Andrea Centrone Albert Davydov Jie Jiang Ruth Pachter Gowoon Cheon Evan Reed Ankit Agrawal Xiaofeng Qian Vinit Sharma Houlong Zhuang Sergei V.Kalinin Bobby G.Sumpter Ghanshyam Pilania Pinar Acar Subhasish Mandal Kristjan Haule David Vanderbilt Karin Rabe Francesca Tavazza 2020npj Computational Materials2020,,1:10
2钠-葡萄糖共转运蛋白-2抑制剂或胰高血糖素样肽-1受体激动剂治疗成人2型糖尿病:临床实践指南显示文摘临床问题对于存在不同心血管风险及肾脏结局的2型糖尿病患者,在原有生活方式干预和/或其他降糖药物的基础上加用钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂的获益及风险是什么?现行做法几十年来,2型糖尿病的治疗决策都以控制血糖为主导。SGLT-2抑制剂和GLP-1受体激动剂在传统观念中常被用于二甲双胍治疗后血糖仍控制不佳的患者。目前这一现状已经发生了改变,这得益于多项临床研究结果。研究显示SGLT-2抑制剂和GLP-1受体激动剂拥有独立于药物降糖作用之外的对于动脉粥样硬化性心血管病(CVD)和慢性肾脏病(CKD)的获益。建议本指南阐述了针对不同风险分层的成人2型糖尿病患者使用SGLT-2抑制剂或GLP-1受体激动剂的建议。•伴有3种或更少的心血管风险因素且不存在CVD或CKD:不建议启动SGLT-2抑制剂或GLP-1受体激动剂治疗。(推荐等级:弱)•伴有3种以上心血管风险因素且不存在CVD或CKD:建议启动SGLT-2抑制剂治疗,不建议启动GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD或CKD:建议启动SGLT-2抑制剂治疗和GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD和CKD:建议启动SGLT-2抑制剂治疗(推荐等级:强)和GLP-1受体激动剂治疗。(推荐等级:弱)•对于那些想要进一步降低CVD和CKD结局风险的患者:推荐优先启用SGLT-2抑制剂治疗而非GLP-1受体激动剂治疗。(推荐等级:弱)这项指南是如何制订的一个由患者、临床医生和方法学家共同组成的国际小组提出了这些推荐意见。这些推荐意见基于可信度较高的指南的标准,并使用GRADE分级方法进行评估。该小组采用了息者个体化的观点。证据一项关于获益与风险的系统综述和网络meta分析(764项随机对照研究,包括421346例参与者)发现SGLT-2抑制剂和GLP-1受体激动剂可以降低总体死亡率、心肌梗死发生率、终末期肾病或肾衰竭的发生率(中等至高等质量的证据)。在不同的亚组中这些药物对卒中、因心力衰竭所致住院和其他主要不良事件有不同的影响。药物绝对获益的程度因患者个体风险的不同有很大的差异。(例如,对于接受了超过5年药物治疗的1000例患者,在最低风险人群中死亡人数减少了5人,在最高风险人群中死亡人数减少了48人)。一项关于预后的综述确认了14种风险预测模型,其中一种(RECODe)在证据总结中报告了大部分基线风险评估数据,小组利用该模型以支持风险分层的建议。考虑到患者的价值观及个体差异,指南推荐的支撑证据包括一项对已发表论文的系统综述、一项患者焦点小组研究、一项临床问题总结,以及一项指南调查。指南解读我们依据不同的CVD和CKD风险水平,综合考虑获益、风险和其他因素的平衡,以及每一个风险组别的实际问题,来对推荐意见进行分层。本指南强烈建议CVD和CKD患者使用SGLT-2抑制剂治疗,这说明专家组认为其具有显著的获益。而对于其他成人2型糖尿病患者,推荐等级较弱,这说明专家组想要在获益、风险及治疗花费上取得一个更好的平衡。临床医生通过该指南可以使用可靠的风险计算模型,如RECODe,来明确其患者的个体心血管和肾脏疾病风险。医患交互式总结临床证据和制订决策有助于患者知晓治疗选择,包括进行共同决策。2型糖尿病人群(全球患病率不断增长1-2)正面临着不断增加的心血管疾病、肾脏病和其他并发症的风险3。数十年来,2型糖尿病的管理始终以控制血糖及糖化血红蛋白(HbA1c)为治疗目标4-5,但是,最近的高质量随机对照研究已经对这种以血糖为中心的治疗模式发起了挑战。研究结果显示,强化血糖控制未必会降低大血管不良事件,它还可能带来不利影响监管机构现在要求新型糖尿病药物必须证明其具有心血管和肾脏获益才能获得批准。对两类新药--钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂(见框图1)的临床试验结果显示,在现有治疗方案(常规治疗)之上加用这些药物,对死亡、心肌梗死、卒中、心力衰竭和肾脏的结局(如进展为终末期肾病)都有获益8-12。Sheyu Li Per Olav Vandvik Lyubov Lytvyn Gordon H Guyatt Suetonia C Palmer Rene Rodriguez-Gutierrez Farid Foroutan Thomas Agoritsas Reed A C Siemieniuk Michael Walsh Lawrie Frere David J Tunnicliffe Evi V Nagler Veena Manja Bjφrn Olav Asvold Vivekanand Jha Mieke Vermandere Karim Gariani Qian Zhao Yan Ren Emma Jane Cartwright Patrick Gee Alan Wickes Linda Fems Robin Wright Ling Li Qiukui Hao Reem A Mustafa 郭鹤鸣(译) 2021英国医学杂志中文版2021,24,9:7
3All-silicon carrier accumulation modulator based on a lateral metal-oxide-semiconductor capacitor显示文摘In silicon photonics, the carrier depletion scheme has been the most commonly used mechanism for demonstrating high-speed electro-optic modulation. However, in terms of phase modulation efficiency, carrieraccumulation-based devices potentially offer almost an order of magnitude improvement over those based on carrier depletion. Previously reported accumulation modulator designs only considered vertical metal-oxidesemiconductor(MOS) capacitors, which imposes serious restrictions on the design flexibility and integratability with other photonic components. In this work, for the first time to our knowledge, we report experimental demonstration of an all-silicon accumulation phase modulator based on a lateral MOS capacitor. Using a Mach–Zehnder interferometer modulator with a 500-μm-long phase shifter, we demonstrate high-speed modulation up to 25 Gbit∕s with a modulation efficiency(V_πL_π) of 1.53 V·cm.KAPIL DEBNATH DAVID J.THOMSON WEIWEI ZHANG ALI Z.KHOKHAR CALLUM LITTLEJOHNS JAMES BYERS LORENZO MASTRONARDI MUHAMMAD K.HUSAIN KOUTA IBUKURO FREOERIC Y.GARDES GRAHAM T,REED SHINICHI SAITO 2018Photonics Research2018,6,5:6
4Effects of water-based binders on electrochemical performance of manganese dioxide cathode in mild aqueous zinc batteries显示文摘In the majority of rechargeable batteries including lithium-ion batteries,polyvinylidene fluoride(PVdF)binders are the most commonly used binder for both anode and cathode.However,using PVdF binder requires the organic solvent of N-methyl-2-pyrrolidone which is expensive,volatile,combustible,toxic,and has poor recyclability.Therefore,switching to aqueous electrode processing routes with non-toxic binders would provide a great leap forward towards the realization of ideally fully sustainable and environmentally friendly electrochemical energy storage devices.Various water-soluble binders(aqueous binders)were characterized and compared to the performance of conventional PVdF.Our study demonstrates that the electrochemical performance of Zn/MnO_(2) aqueous batteries is significantly improved by using sodium carboxymethyl cellulose(CMC)binder.In addition,CMC binders offer desirable adhesion,good wettability,homogeneous material distribution,and strong chemical stability at certain pH levels(3.5-5)without any decomposition for long-cycle life.Hee Jung Chang Ismael A.Rodriguez-Pere Matthew Fayette Nathan L.Canfield Huilin Pan Daiwon Choi Xiaolin Li David Reed 2021Carbon Energy2021,3,3:5

8Towards an all-vanadium redox flow battery with higher theoretical volumetric capacities by utilizing the VO^2+/V^3+ couple显示文摘An all-vanadium redox flow battery with V(IV)as the sole parent active species is developed by accessing the VO^(2+)/V^(3+)redox couple.These batteries,referred to as V4RBs,possess a higher theoretical volumetric capacity than traditional VRBs.Copper ions were identified as an effective additive to boost the battery performance.Wentao Duan Bin Li Dongping Lu Xiaoliang Wei Zimin Nie Vijayakumar Murugesan James P.

14Changes in human hepatic metabolism in steatosis and cirrhosis显示文摘AIM To understand the underlying metabolic changes in human liver disease we have applied nuclear magnetic resonance(NMR) metabolomics analysis to human liver tissue.METHODS We have carried out pilot study using 1H-NMR to derive metabolomic signatures from human liver from patients with steatosis, nonalcoholic steatohepatitis(NASH) or alcohol-related liver damage(ARLD) to identify species that can predict outcome and discriminate between alcohol and metabolic-induced liver injuries. RESULTS Changes in branched chain amino acid homeostasis, tricarboxylic acid cycle and purine biosynthesis intermediates along with betaine were associated with the development of cirrhosis in both ARLD and nonalcoholic fatty liver disease. Species such as propylene glycol and as yet unidentified moieties that allowed discrimination between NASH and ARLD samples were also detected using our approach.CONCLUSION Our high throughput, non-destructive technique for multiple analyte quantification in human liver specimens has potential for identification of biomarkers with prognostic and diagnostic significance.Zoe Schofield Michelle AC Reed Philip N Newsome David H Adams Ulrich L Günther Patricia F Lalor 2017World Journal of Gastroenterology2017,23,15:1
