冬季流感严重危害人类健康,甚至会威胁生命,我们究竟有什么办法预防流感呢?目前,美国密歇根大学 Betsy Foxman 和同事最新研究表明,呼吸道微生物群可能与流感易感性密切相关。这项研究报告发表在 1 月 9 日出版的《美国公共科学图书馆 · 综合》杂志上。流感病毒是流感病原体,主要侵袭目标是人体呼吸道,感染上皮细胞。鼻子和喉咙的上皮细胞被复杂的细菌群落包围,因此 Betsy Foxman 和同事推测认为,这些呼吸道微生物群可能与病毒相互作用,并在人体对流感预防方面充分发挥作用。在这项研究中,研究人员对 2012—2014 年登记的 144 个尼加拉瓜家庭进行了分析,这些家庭中有一位成员被确认患有流感,包括成年人和儿童的所有家庭成员都接受为期两个星期的监测。研究人员对每个家庭进行 5 次回访信息统计,对所有家庭成员的呼吸道微生物取样,并对监控测试者进行症状日志记录。研究者使用统计模型,对每次测试的家庭成员呼吸道微生物群分类为两个不同种群类型,尽管大约一半的测试者在研究测试过程中体内微生物群类型发生了变化。接下来,研究人员将参与者微生物类型与他们流感易感性进行了对比分析。结果发现,跨年龄组的一种呼吸道微生物类型显示出对流感的易感性降低,这种微生物类型在婴儿和儿童群体中并不常见,而且与年龄较大的青少年和成年人相比,其稳定性较低。虽然微生物种群和流感易感性之间的联系在这项研究...

据《世界阿尔茨海默症2018年报告》显示,每3秒钟,全球就有一位痴呆症患者产生。全球目前至少有5000万的痴呆患者。在中国,目前约有1000万阿尔茨海默症患者,预计到2050年,患者数将超过4000万人,比加拿大的总人口还要多。因此,理解这种疾病的发病原因比以往任何时候都更加迫切。此前有许多研究已经发现了一些增加罹患痴呆症风险的因素。有些因素是无法阻止的,如衰老。然而,其他潜在风险因素是有可能避免的,比如吸烟与饮酒。确定这些风险因素非常重要,因为它们有助于预防或延缓痴呆症的发生。近日,发表在JAMA Network Open上的一篇研究,来自美国哈佛大学T.H.Chan公共卫生学院的研究人员设计了一项研究以寻找痴呆症与饮酒之间的联系。尽管已有关于饮酒与痴呆症的相关研究,但研究的科学性还有所欠缺。例如,在之前的一项研究中,研究人员计算了每年的日平均饮酒量。但是以这种方式计算的每日平均饮酒量会忽略酒精含量和饮酒频率的细微差别。这一点非常重要。例如,每周有一天喝7杯啤酒可能会产生不同于每晚喝1杯啤酒的影响,尽管消耗的酒精量是一样的。另一项研究的作者得出结论,中年酗酒会增加患痴呆症的风险。然而,目前还不清楚经常性的少量饮酒是否有同样的影响。其他关于酒精、痴呆症风险、载脂蛋白E4(APOE E4)之间关联的研究使这一问题的答案更加复杂。这种基因变异与患阿尔茨海默症的风险增加有关。较早的一项研...

描述

The EVOS M7000 Imaging System is a high-performance, fully automated, inverted, multi-channel fluorescence and transmitted light imaging system. It was developed to meet today’s expectations for image quality, user interface interactions, data generation speed and flexibility, and end-user value. The powerful and time-saving acquisition tools with enhanced autofocus algorithms and automated routines for microwell plate assays, time-lapse live cell imaging, area scanning in time lapse and Z-stacks in scan mode, and a superb optomechanical design enable the generation of publication-quality images and data with just a few clicks when and where needed.

The EVOS M7000 Imaging System offers these advantages:
• Outstanding image quality and versatility with a 5-position objective turret, 4-color LED fluorescence and transmitted light channels, and 3.2 MP CMOS color and B/W cameras
• Exceptional usability with fully automated X/Y scanning stage, autofocus, and acquisition routines
• High-speed image acquisition coupled with multi-position well scanning, and Z-stack and tile-stitch options lend power and flexibility to your data generation
• Fully integrated time-lapse live cell imaging using the optional EVOS Onstage Incubator for precise control of temperature, gases for normoxic or hypoxic conditions, and humidity
• Powerful image analysis capabilities for cell segmentation and quantification with the optional Celleste™ Image Analysis Software

Fully automated imaging system
The EVOS M7000 system combines and integrates precision components with a unique modern design functionality that enables high-quality automated fluorescence imaging anywhere with unprecedented workflow efficiency. Full automation of the precision X/Y-stage movement; changing of the 4 LED fluorescent light cubes, 5-position objective turret, focus, and exposure; and switching of the dual camera make the EVOS M7000 system an exceptional platform for a variety of demanding imaging applications. Through the intuitive acquisition interface, you can program the EVOS M7000 system to run well-plate scanning, time lapse experiments, and tile-stitch/montage area scans in Z-stack and/or time-lapse modes in your vessel of choice. For live cell imaging over multiple hours or days, the optional EVOS Onstage Incubator, which functions as an environmental chamber on top of the microscope stage, is operated seamlessly from within the instrument interface. The EVOS M7000 system is compatible with all accessories for the predecessor EVOS FL Auto imaging system.

Versatile and highly configurable
With a 5-position objective turret and the ability to simultaneous acquire images in four fluorescence channels plus transmitted light, the optical system can be easily configured to meet your needs. Choose from our broad range of high quality coverslip-corrected and long-working-distance objectives for use with plastic vessels or glass sides. Available from 1.25X to 100X magnification in achromat, fluorite, or apochromat models, together with over twenty LED light cubes, the sample imaging options are limitless. Dual monochrome and color high-sensitivity dual CMOS cameras enable seamless imaging of both fluorescent and chromogenically stained samples. Interchangeable vessel holders accommodate most vessel types and sizes, including slides, multi-well plates, culture flasks, and Petri dishes, and afford precise control and sample alignment by the automated stage. The vessel creation wizard in the user interface enables creation of profiles for custom sample vessels.

Powerful software
The EVOS M7000 software presents users with an extensive suite of tools for acquisition, visualization, and analysis.

Celleste software offers powerful tools for image segmentation and classification that can be applied to a range of cell analysis applications for counting and measuring intensity, area, and shape changes over time, and more.

Smart LED illumination technology
All EVOS fluorescence imaging systems utilize our proprietary LED light cubes. This light engine outputs remarkable intensity over a short light path and delivers incomparable fluorophore excitation. Each light cube contains a precisely matched set of optical components to optimize the position, evenness, and intensity of the light beam. Digitally controlled LED light sources allow adjustment of illumination levels to the sample and experimental conditions to minimize the risk of photo-toxicity and photo-bleaching in time-lapse studies. Hard-coated filters give sharper edges and significantly higher transmission efficiencies than traditional soft-coated filters.

Easy to use and reliable
The EVOS M7000 Imaging System is powerful, yet offers the simplicity of plug-and-play. Like other EVOS systems, it requires no warm-up or cool-down periods. The LED light source guarantees exceptional stability and durability, so you can turn the unit on and off whenever you need to image a sample. The environmentally safe, mercury-free LED bulbs are rated for >50,000 hours, compared to 300 hours for a typical mercury bulb and 1,500 hours for a metal halide bulb. The long lifetime and low energy consumption translate into significantly lower operating costs compared to instruments with conventional light sources. The EVOS M7000 system is powered by an external Dell PC with an Intel Core i7-8700 processor, 32 GB DDR4 RAM, 512 GB PCIe SSD, and NVIDIA Quadro P1000 with 4 GB discrete video graphics running Windows 10, designed to operate with touchscreen monitor and microscope. Whether acquiring single images or setting up automated routines, the EVOS M7000 system is remarkably easy to use and run. The 1920 x 1080 pixel resolution 23' LCD touch screen monitor enables “finger swipes” to expand or zoom in on images, and moving between microwell plate wells is done by a single touch. Operation is also also fully controllable via mouse.

The EVOS imaging systems are built from the ground up to maximize performance and optimize workflow. You will be astonished at how easy it is to operate and amazed at how extraordinary your images look on-screen.
