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 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. The user interface was designed with a strong emphasis on usability, including an option to view samples in a single field mode (Field View) or in a window that covers a much larger area (Area View). By using a zoom function, the Area View size can be adjusted. A user can explore a large sample area at low magnification, define regions of interest, and then seamlessly transition to the Scan function in Automate Mode and execute an area scan at higher magnification.

The enhanced power of the EVOS M7000 system enables more demanding automated acquisition routines like area scanning in time lapse and Z-stacks in scan mode to be performed. Visualization capabilities include multi-field image viewing gallery, mosaic tiling and tile stitching options, Z-stack visualization, and a video recording and movie maker/editor for time lapse sequences. The EVOS M7000 system is fully compatible with the EVOS Onstage Incubator environmental chamber for control of temperature, gases, and humidity. With the ability generate both hypoxic and normoxic conditions, it is possible to study live cells over extended periods with highly flexible time lapse automation routines.

For users needing more powerful image analysis capabilities, images acquired on the EVOS M7000 system can be analyzed directly using the optional Celleste Image Analysis Software. 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.
