CORE--TISSUE PROCUREMENT FACILITY

核心B的总体目标是为项目1-4的研究人员提供定义良好的组织样本，并维护一个完整和准确的互动数据库。核心B获取组织并提供数据管理，以支持项目。血液和粘膜样本被处理用于实验和/或存储，相关的临床数据被收集并输入到临床数据库中。组织样本与来自捐赠者的临床和家族特征数据相匹配，这些数据与相关的免疫学和遗传学参数相互参照。采购技术员在医生就诊时收集临床和研究研究患者的样本，参加内窥镜检查程序以获取活检材料，并与医院外科医生和病理学家协调，从肠道切除中获取粘膜样本。对人和啮齿动物的粘膜样本进行组织病理学评估。对临床数据和基础科学研究的结果进行协调，以便通过各种临床、亚临床、遗传和流行病学参数对人群进行分层。核心B提供的服务随着数据管理责任的增加而扩大，包括数据库管理和数据列报和实验发展的统计服务。该中心鼓励多名调查人员使用来自一名捐赠者的样本。核心服务已进一步扩展到临床试验支持以及临床研究的协调和翻译方面。核心人员中包括两名医生和研究护士，并将与锡达斯-西奈综合临床研究中心合作提供额外的临床服务。研究研究协调员将帮助确定研究人群，提供掩蔽和随机方案。

The overall goal of Core B is to provide investigators of Projects 1-4 with well-defined tissue samples, and maintain a complete and accurate interactive database. Core B obtain the tissues and provides data management in support of the projects. Blood and mucosal samples are processed for experimental use and/or storage, and associated clinical data is gathered and entered into the clinical database. Tissue samples are matched with clinical and familial trait data from the donor cross- referenced with associated immunologic and genetic parameters. The procurement technician collects samples from clinical and research study patients at physician visits, attends endoscopic procedures to procure biopsy material and coordinates with hospital surgeons and pathologists to obtain mucosal samples from intestinal resection. Histopathological evaluation of human and rodent mucosal samples is performed. Clinical data and results from basic science studies are coordinated to allow stratification of populations by a variety of clinical, subclinical, genetic and epidemiologic parameters. The services provided by Core B have expanded with the increase in data management responsibilities to include database management and statistical services for data presentation and experimental development. The Core encourages use of samples from one donor by several investigators. Core services have been further expanded to clinical trial support, and coordination and translational aspects of clinical research. Two physicians and research nurse are included among the Core personnel and additional clinical services will be provided in cooperation with the Cedars-Sinai General Clinical Research Center. The Research Studies Coordinator will help to identify study populations, provide masking and randomization schemes.
