PROJECT ABSTRACT/SUMMARY – ADMINISTRATIVE CORE Traditionally, nutrition research has relied heavily on self-reported measures of dietary intake that are often prone to measurement error. To date, only a few recovery biomarkers of nutrient intake have been established, including doubly labeled water for estimating energy intake, 24-hour urinary nitrogen for estimating protein intake, and 24-hour urinary potassium as a biomarker of potassium intake. This highlights the urgent need to identify further objective and robust biomarkers of food intakes. Recent advances in high-throughput -omics technologies and the development of novel bioinformatic tools now enable the unbiased discovery of novel biomarkers that are sensitive and specific to intakes of foods and food groups. The overall objective of the Dietary Biomarker Development Center (DBDC) at Harvard University is to identify and validate dietary biomarkers of important protein and carbohydrate food sources in the US diet by using the state-of-the-art metabolomic techniques and through a combination of well-controlled dietary intervention trials and observational studies. Our objective is to establish an Administrative Core will play scientific and administrative leadership roles by integrating the Intervention Core, Data Analysis Core, Metabolomics Core, and the Biomarkers Project to improve efficiency, enhance innovation, and extend the breadth and depth of the science within the DBDC at Harvard and across the DBDC’s and the Data Coordinating Center (DCC). The Core will be led by Dr. Frank Hu, with co-leadership provided by Dr. Clary Clish. Additional key leadership will be provided by Executive Committee (EC) members, including the Core PIs and Directors and the Project Director, Dr. Shilpa Bhupathiraju. The DBDC at Harvard Center brings together investigators of diverse backgrounds and expertise to identify novel biomarkers of several important carbohydrate and protein sources in the US diet. The expertise in our research team is wide-ranging, covering dietary assessment, population science, nutritional biochemistry, bioinformatics, and biotechnologies. The stimulating intellectual environment in the Longwood/Harvard Medical Area is highly conducive for carrying out this research. The Center will take full advantage of institutional commitment and resources provided by HSPH and other participating institutions, as well as those provided by the broader Harvard community, such as Harvard Catalyst and the Harvard Nutrition and Obesity Research Center. The infrastructure for the Administrative Core will provide a strong and visionary leadership role in science, administration, and dissemination for the DBDC at Harvard University.

项目摘要/摘要 - 行政核心 传统上，营养研究大大挽救了自我报告的饮食摄入量的措施 容易出现测量误差。迄今为止，仅建立了少数营养素摄入的生物标志物， 包括估计能量摄入量的两倍标记的水，24小时的尿氮用于估计蛋白 摄入量和24小时的尿钾作为钾摄入的生物标志物。这突出了迫切需要 确定食物摄入量的进一步目标和强大的生物标志物。高通量 - 摩学的最新进展 技术和新颖的生物信息学工具的开发使得无偏见的新颖发现 对食物和食物群的摄入量敏感且特异的生物标志物。总体目标 哈佛大学的饮食生物标志物开发中心（DBDC）是识别和验证饮食 美国饮食中重要的蛋白质和碳氢化食物来源的生物标志物通过使用最先进的生物标志物 代谢组技术以及通过良好控制的饮食干预试验和 观察性研究。我们的目标是建立行政核心将发挥科学作用，并且 通过整合干预核心，数据分析核心，代谢组学核心，行政领导角色， 以及生物标志物项目，以提高效率，提高创新并扩大其广度和深度 在哈佛大学，跨DBDC和数据协调中心（DCC）的DBDC内部的科学。 Core将由Frank Hu博士领导，由Clary Clish博士共同领导。其他关键领导将会 由执行委员会（EC）成员提供，包括核心PIS和董事和项目 主任Shilpa Bhupathiraju博士。哈佛中心的DBDC汇集了潜水员的调查员 背景和专业知识，以识别几种重要碳水和蛋白质来源的新型生物标志物 在美国饮食中。我们的研究团队的专业知识是广泛的，涵盖了饮食评估，人口 科学，营养生物化学，生物信息学和生物技术。刺激的智力环境 在朗伍德/哈佛大学，医疗区对于进行这项研究具有很高的导电性。中心将采取 HSPH和其他参与机构提供的机构承诺和资源的全部优势， 以及哈佛大学的更广泛的哈佛大学催化剂和哈佛大学等人提供的 营养与肥胖研究中心。行政核心的基础架构将提供强大的 哈佛大学DBDC的科学，管理和传播中有远见的领导角色。
