1儿童和青少年进食障碍显示文摘进食障碍是一组疾病,是与饮食、保持体型、体重相关的不良观念伴随的行为,包括节食、暴饮暴食、锻炼过度、呕吐和使用泻药。尽管男性青少年和成人也有发生,但是进食障碍在青少年女性中更常见(图1)。进食障碍患者有高致死率和致残率,但是广泛证据显示,许多患者要么没有就诊,要么没有接受治疗。最近的指南强调了针对儿童和青少年进食障碍进行早期干预的重要性;为了达到更好的治疗效果,治疗开始得越早越好。Helen Bould Claudia Newbegin Anne Stewart Alan Stein Mina Fazel 张春雨(译) 2018英国医学杂志中文版2018,21,8:2

3A flexible protruding microelectrode array for neural interfacing in bioelectronic medicine显示文摘Recording neural signals from delicate autonomic nerves is a challenging task that requires the development of a lowinvasive neural interface with highly selective,micrometer-sized electrodes.This paper reports on the development of a three-dimensional(3D)protruding thin-film microelectrode array(MEA),which is intended to be used for recording low-amplitude neural signals from pelvic nervous structures by penetrating the nerves transversely to reduce the distance to the axons.Cylindrical gold pillars(O 20 or 50μm,~60μm height)were fabricated on a micromachined polyimide substrate in an electroplating process.Their sidewalls were insulated with parylene C,and their tips were optionally modified by wet etching and/or the application of a titanium nitride(TiN)coating.The microelectrodes modified by these combined techniques exhibited low impedances(~7 kΩ at 1 kHz for ∅ 50μm microelectrode with the exposed surface area of~5000μm^(2))and low intrinsic noise levels.Their functionalities were evaluated in an ex vivo pilot study with mouse retinae,in which spontaneous neuronal spikes were recorded with amplitudes of up to 66μV.This novel process strategy for fabricating flexible,3D neural interfaces with low-impedance microelectrodes has the potential to selectively record neural signals from not only delicate structures such as retinal cells but also autonomic nerves with improved signal quality to study neural circuits and develop stimulation strategies in bioelectronic medicine,e.g.,for the control of vital digestive functions.Helen Steins Michael Mierzejewski Lisa Brauns Angelika Stumpf Alina Kohler Gerhard Heusel Andrea Corna Thoralf Herrmann Peter D.Jones Günther Zeck Rene von Metzen Thomas Stieglitz 2022Microsystems & Nanoengineering2022,8,6:0
4Mobilizing Crop Biodiversity显示文摘Over the past 70 years,the world has witnessed extraordinary growth in crop productivity,enabled by a suite of technological advances,including higher yielding crop varieties,improved farm management,synthetic agrochemicals,and agricultural mechanization.While this'Green Revolution'intensified crop production,and is credited with reducing famine and malnutrition,its benefits were accompanied by several undesirable collateral effects(Pingali,2012).These include a narrowing of agricultural biodiversity,stemming from increased monoculture and greater reliance on a smaller number of crops and crop varieties for the majority of our calories.This reduction in diversity has created vulnerabilities to pest and disease epidemics,climate variation,and ultimately to human health(Harlan,1972).Susan McCouch Zahra Katy Navabi Michael Abberton Noelle L.Anglin Rosa Lia Barbieri Michael Baum Kirstin Bett Helen Booker Gerald L.Brown Glenn J.Bryan Luigi Cattivelli David Charest Kellye Eversole Marcelo Freitas Kioumars Ghamkhar Dario Grattipaglia Robert Henry Maria Cleria Valadares Inglis Tofazzal Islam Zakaria Kehel Paul J.Kersey Graham J.King Stephen Kresovich Emily Marden Sean Mayes Marie Noelle Ndjiondjiop Henry T.Nguyen Samuel Rezende Paiva Roberto Papa Peter W.B.Phillips Awais Rasheed Christopher Richards Mathieu Flouard Maria Jose Amstalden Sampaio Uwe Scholz Paul D.Shaw Brad Sherman S.Evan Staton Nils Stein Jan Svensson Mark Tester Jose Francisco Montenegro Valls Rajeev Varshney Stephen Visscher Eric von Wettberg Robbie Waugh Peter Wenzl Loren H.Rieseberg 2020Molecular Plant2020,13,10:0
