2021年05月30日讯 /生物谷BIOON/ --目前,国外新冠肺炎疫情仍在迅速蔓延。根据百度《新型冠状病毒肺炎疫情实时大数据报告》,截止2021年05月30日19时,全球累计确诊超过1.7亿(1.7068亿)例,死亡超过354.9万例。近日,辉瑞(Pfizer)与合作伙伴BioNTech联合宣布,其COVID-19 mRNA疫苗Comirnaty(BNT162b2)在欧盟的有条件营销授权(CMA)已扩大至纳入12-15岁的青少年。在此之前,欧洲药品管理局(EMA)人用医药产品委员会(CHMP)发布积极审查意见,推荐批准Comirnaty用于这一年龄组人群。此次Comirnaty CMA适应症扩展,在欧盟所有27个成员国均有效。Comirnaty是第一个在欧盟获得授权的COVID-19疫苗,也是第一个将其CMA扩展到青少年的疫苗。Comirnaty在欧盟成员国的分发和接种,将继续根据欧盟确定的人口和各个国家的指南来实施。在美国方面,今年5月10日,FDA批准扩大Comirnaty的紧急使用授权(EUA),纳入12-15岁青少年群体。值得一提的是,Comirnaty是在美国被批准用于这一年龄组的首个COVID-19疫苗。此前,FDA已授予Comirnaty用于≥16岁人群进行主动免疫的EUA。BioNTech首席执行官兼联合创始人Ugur Sahin医学博士表示:“今天,我们在欧盟...

2019年8月23日讯 /生物谷BIOON /——2019年6月,欧洲大部分地区遭遇了早期热浪,法国的气温达到了创纪录的46摄氏度(115华氏度)。热浪的特点是在几天几夜持续高温。它们对我们的日常生活有重要的影响--我们感到过热和疲劳。当热浪来袭时,许多政府会启动一项'热行动计划',建议受影响的人多喝水,避免剧烈运动,保持凉爽。如果不这样做,就有中暑的风险,而中暑有可能危及生命。但是,人体究竟是如何应对如此极端的温度的呢?为什么高温如此危险呢?哪些器官受到影响,什么时候情况会变得更糟?图片来源:http://cn.bing.com保持凉爽人体的核心温度通常在36到38摄氏度之间波动(97到99华氏度)。在这个温度范围内,生化反应可以正常进行,这对细胞和器官的正常功能至关重要。人类的身体也能很好地应对各种可能威胁其核心温度的环境条件。当核心温度偏离正常范围时,身体就会启动生理反应,使温度恢复正常。这种温度调节反应相当于你家的恒温器;一旦内部温度偏离理想温度,加热或冷却系统就会被激活,回到理想温度。在人体中,这个恒温器位于我们大脑的底部,一个叫做下丘脑的区域。位于我们皮肤、肌肉和其他器官的温度传感器提供的信息被分析,必要时,启动生理反应。对温度升高的第一个也是最重要的反应是通过我们身体的皮肤和四肢,如手和脚散热。我们开始产生汗液,汗液会在皮肤上蒸发,在这个过程中散热。这...

今日,美国FDA批准罗氏(Roche)公司开发的NTRK,ROS1和ALK抑制剂Rozlytrek(entrectinib)上市,治疗携带NTRK基因融合的实体瘤患者,以及携带ROS1基因突变的非小细胞肺癌患者。这也是美国FDA批准的第三款“不限癌种”的抗癌疗法。自从去年Loxo Oncology/拜耳(Bayer)公司联合开发的TRK抑制剂Vitrakvi(larotrectinib)获批以来。“不限癌种”抗癌疗法得到了广大业界人士和患者的关注。还有哪些“不限癌种“疗法即将问世?“不限癌种“的抗癌疗法发展的前景如何?今天的这篇文章里,药明康德内容团队将结合公开资料,与读者分享这些问题的答案。“不限癌种“疗法的理论基础和面对的挑战我们知道,基因突变是驱动正常细胞癌变的关键。近年来高通量测序技术的进步,让我们获得了许多对癌症背后的分子生物学机理的洞见。基于这些洞见,我们对癌症的分类不再局限于癌症起源的组织,而是基于肿瘤细胞携带的特定基因变异。这一基于分子生物学生物标志物的分类方法加快了靶向疗法的开发,而“不限癌种“的抗癌疗法可以说是靶向疗法中比较特别的一个分支。这些靶向疗法的靶点在起源于不同组织的多种癌症中存在,而且”不限癌种“疗法能够在多种癌症类型中表现出卓越的疗效。例如去年获批的Vitrakvi在携带NTRK基因融合的患者中能够达到81%的总缓解率。而刚刚获得FDA批准的Rozl...

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.
