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...

5月28日,南方医科大学南方医院教授李国新作为通讯作者发布了胃癌微创手术最新临床研究成果,该研究在全球范围内,首次提供了腹腔镜微创治疗局部进展期胃癌的高级别循证医学证据,揭示了腹腔镜微创手术治疗局部进展期胃癌具有确切的远期疗效与显着的微创获益。该研究在国际顶级医学期刊《美国医学会杂志》(以下简称为《JAMA》)在线发表,首次为世界胃癌治疗提供了“中国模式”,将使得更多患者受益于腹腔镜微创手术。胃癌是世界第二高发恶性肿瘤,42%的新发病例在中国,80%的患者在就诊时已发展至局部进展期,是严重影响国民健康的重大肿瘤疾病。2009年,李国新牵头组织,成立了中国腹腔镜胃肠外科研究组(CLASS),开展胃癌微创手术关键技术研究,建立了标准化手术操作方案。此多中心成员单位包括北京大学肿瘤医院(季加孚、苏向前、李子禹教授)、中国人民解放军301医院(杜晓辉教授)、复旦大学中山医院(孙益红教授)、上海交通大学瑞金医院(胡伟国教授)等。该研究组经过建立全国多中心数据库、开展系列多中心回顾性研究作为前期基础,于2012年启动了CLASS研究组的首项前瞻性临床研究(CLASS-01研究)。该研究旨在回答腹腔镜治疗局部进展期胃癌的安全性和肿瘤学疗效问题,以临床分期T2、T3或T4a的胃癌患者为研究对象,采用多中心、随机对照的试验设计,以3年无瘤生存率为主要研究终点,手术并发症、3年总生存率、术后关键恢复指...

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® FL Imaging System is a fully integrated, digital, inverted imaging system for four-color fluorescence and transmitted-light applications. It is powerful, yet easy-to-use and delivers high-definition images with exceptional convenience. The unique light cubes, sensitive camera, and precision-engineered optical system make the EVOS® FL system ideal for both demanding and routine fluorescence imaging applications.

The EVOS® FL Imaging System offers you these important advantages:

• Easy installation; no maintenance, assembly, alignment, or calibration
• For four-color fluorescence and transmitted light applications
• Five-position objective turret with front controls
• On-board software
• All-in-one design: digital camera, precision optics, LCD display, and USB storage

Fully Integrated Imaging System
The EVOS® FL system represents a new concept in transmitted light inverted microscopy. It is a fully integrated imaging system that combines precision optics, a 15' high-resolution LCD display, and a highly sensitive Sony ICX445 monochrome CCD camera (1280 x 960 pixel resolution, 1.3 Megapixels). Images are seamlessly acquired through the intuitive user interface using a mouse for easy control. Monochrome cameras are commonly used for high-performance fluorescence applications and provide the best sensitivity for detection of faint fluorescence signals. Color cameras, as on the EVOS® FL Color System, have lower fluorescence sensitivity but have the advantage of being able to differentiate structures by color in transmitted light (e.g., imaging stained tissue samples).

Versatile and Highly Configurable
The EVOS® FL system features an easily accessible 5-position objective turret and a 3-position condenser turret. The 4 fluorescence light cubes are lever-actioned for rapid and easy selection. The optical system can be configured to best meet your needs using our full range of high-quality objectives from 2x to 100x magnification. Lighting settings are automatically adjusted to match the objective magnification. The EVOS® FL system features a mechanical stage with X/Y-axis fine-positioning using control knobs conveniently located on the left side and the front of the stage. The stage accommodates EVOS® vessel holders that provide a perfect fit for most vessel types and sizes. Interchangeable stage plates accommodate most vessel types and sizes, including flasks, Petri dishes, multi-well plates, and slides.

Smart LED Illumination Technology
All EVOS® fluorescence imaging systems utilize our unique, proprietary LED light cubes. This world-leading light engine outputs remarkable intensity over a short light-path that delivers superior 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, dramatically improving control over photobleaching. Hard-coated filters give sharper edges and significantly higher transmission efficiencies than traditional soft-coated filters.

Integrated Software
The on-board computer makes the EVOS® FL system easy to run and use, and the intuitive, comprehensive software facilitates both image acquisition and analysis. Modules include time-lapse acquisition, manual-assist cell counting, and image review. Saved user settings work in conjunction with 'smart' controls to help increase efficiency and ease of use. Image data are saved to a USB flash drive for easy, portable data transfer or to a Windows-networked local server. Images can be saved in PNG, JPEG, BMP, and TIFF formats with a maximum captured image resolution of 1280 x 960 pixels.

These features make the EVOS® FL system ideal for both routine and demanding fluorescence imaging applications such as GFP-vector transfection efficiency analysis, routine cell and tissue culture, cell confluence determination, stem cell growth and differentiation, and developmental biology and tissue slice analyses. And the compact footprint makes it as easy to use the EVOS® FL system in a cell culture hood as on the bench.

Easy to Use and Reliable
The EVOS® FL Imaging System is plug-and-play. In addition to an exceptionally easy set-up and installation, it requires no warm-up or cool-down periods. The LED light source offers 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 (~17 years) of life, compared to 300 hours for a typical mercury bulb and 1,500 hours for a metal halide bulb. The long life and low energy consumption translate into significantly lower operating costs compared to instruments with conventional light sources. Finally, the advanced ergonomic design of the EVOS® systems removes the strain associated with conventional microscopes, enables shared viewing, and makes moving the units easy. For extended or precision use, the EVOS® arm rest provides comfortable support.

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.
