DESCRIPTION (provided by applicant): The Imaging Core of the Cleveland Clinic Lerner Research Institute (LRI) and a group of seventeen NIH-funded investigators request funds to purchase a transmission electron microscope (TEM) - specifically the FEI Tecnai Spirit BioTwin. The Imaging Core was established sixteen years ago to provide leading-edge microscopy equipment and expertise for the Cleveland Clinic research community. The Core has a 21-year-old FEI CM12 TEM, used by 58 registered investigators from 18 departments. This instrument has served our researchers well, but has required more frequent service calls and was, in fact, declared obsolete by the manufacturer at the end of last year (and is no longer eligible for a full service contract). Besides the problems caused for research projects by equipment downtime, our film-based TEM is slow, unreliable, and expensive. The instrument we are requesting herein will provide a dependable resource for all of the basic capabilities of the existing TEM, but will also offer digital imaging. Although our Core provides a great array of top-notch microscopes for biomedical imaging, there are many NIH-funded research goals that can only be pursued with electron microscopy, making it essential for a facility such as ours to have an up-to-date instrument. Knowledge obtained from the projects highlighted here will hopefully lead to better modes of prevention and treatment for conditions such as inflammatory diseases, pelvic floor disorders, pulmonary arterial hypertension, cancer, kidney failure, Alzheimer's disease, atherosclerosis, atrial fibrillation, and birth defects. Placing the system in the Imaging Core - with its centrality in a significant research facility - will not only maximize its benefits for a variety of health-related investigations, but will assure its management by a skilled staff. Dr. Judith Drazba, LRI Imaging Core Director, has over twenty seven years electron microscopy experience, sixteen of them running this facility. A full-time EM technician, also with long experience, oversees the operation of the TEM and provides complete sample preparation. A Core manager also assists with user services and equipment troubleshooting and maintenance. Finally, the Lerner Research Institute which has a long history of strong support for centralized facilities continues its commitment to the Imaging Core by providing funds for salary support, service contracts, and infrastructure. PUBLIC HEALTH RELEVANCE: Use of the electron microscope proposed in this grant will give researchers the ability to produce highly magnified images of cells and tissues to see details on a much smaller scale than with light microscopes. Observing the ultrastructure of these samples leads to a better understanding of how they are organized and how they operate. With the knowledge obtained from use of this instrument, our investigators hope to discover better modes of prevention and treatment for conditions such as inflammatory diseases, pelvic floor disorders, pulmonary arterial hypertension, cancer, kidney failure, Alzheimer's disease, atherosclerosis, atrial fibrillation, and birth defects.

描述（由申请人提供）：克利夫兰诊所Lerner Research Institute（LRI）的成像核心和一组17名NIH资助的研究人员要求资金购买传输电子显微镜（TEM） - 特别是Fei Tecnai Spirit Biotwin。成像核心是16年前建立的，目的是为克利夫兰诊所研究社区提供领先的显微镜设备和专业知识。该核心有一个21岁的FEI CM12 TEM，由来自18个部门的58名注册调查员使用。该工具为我们的研究人员提供了很好的服务，但需要更频繁的服务电话，实际上，该工具在去年年底被制造商宣布为过时（并且不再有资格获得全面服务合同）。除了设备停机时间为研究项目造成的问题外，我们的基于电影的TEM还是缓慢，不可靠且昂贵的。我们在此要求的仪器将为现有TEM的所有基本功能提供可靠的资源，但也将提供数字成像。尽管我们的核心为生物医学成像提供了一系列一流的一流显微镜，但是有许多NIH资助的研究目标只能使用电子显微镜进行，因此对于像我们这样的设施具有最新的设施至关重要乐器。从这里突出显示的项目获得的知识将有望为炎症性疾病，骨盆底疾病，肺动脉高压，癌症，肾衰竭，阿尔茨海默氏病，动脉粥样硬化，动脉粥样硬化，心脏纤维化和孕育缺陷等疾病提供更好的预防和治疗方式。将系统置于成像核心（将其中心地带放在重要的研究机构中）不仅将最大程度地提高其与健康相关调查的好处，而且还将确保由熟练的员工确保其管理。 LRI成像核心总监Judith Drazba博士拥有超过27年的电子显微镜经验，其中有16年经营此设施。一名具有长期经验的全日制EM技术人员负责监督TEM的操作并提供完整的样品准备。核心经理还协助用户服务和设备故障排除和维护。最后，通过为薪水支持，服务合同和基础设施提供资金，对集中式设施有丰富支持的勒纳研究所（Lerner Research Institute）持续了大力支持。 公共卫生相关性：本赠款中提出的电子显微镜的使用将使研究人员能够产生高度放大的细胞和组织图像，以比光显微镜更小得多。观察这些样品的超微结构会使人们更好地了解它们的组织方式和运作方式。借助使用该仪器获得的知识，我们的研究人员希望发现炎性疾病，骨盆底疾病，肺动脉高压，癌症，肾衰竭，阿尔茨海默氏病，动脉粥样硬化，动脉粥样硬化，动脉粥样硬化，心脏纤维化和心脏纤维化和心脏原纤维化以及心脏纤维化和心脏纤维化和心动性疾病等疾病的更好的预防和治疗方式出生缺陷。
