The iLab North American server has been restored and the site is now operational. Data, like submitted reservations and project requests are being migrated back into the site and we can assure you that no data has been lost. Data is being restored, starting with the most recent and as it is being added to the new search server, it will become available on the iLab site. Some items like billing invoices may not be visible on the site at this moment and during this time, users may experience some general slowness when using the site.

NORC Facility

Overview of Services

The Mid-Atlantic Nutrition Obesity Research Center was established to promote and support research related to Nutrition and Obesity at University of Maryland Baltimore and The Johns Hopkins Medical Institutions. The Mid-Atlantic NORC is led by Drs. Simeon Taylor (Director) and Braxton Mitchell (Associate Director), who are Co-Principal Investigators on the NIH grant that supports the NORC (P30DK072488). To achieve its mission, the Mid-Atlantic NORC has established biomedical research cores, which provides services to Nutrition and Obesity Researchers at the parent institutions:

  • Biological Mechanisms and Functional Genomics (BMFG) Core (Simeon Taylor, MD, PhD, Director; Carole Sztalryd, PhD, Director of the Biological Mechanisms Sub-Core; Norann Zaghloul, PhD, Director of the Functional Genomics Sub-Core). The Core’s principal offers services related to cell biology, biochemistry, and in vivo animal models. Under Dr. Sztalryd’s supervision, the Biological Mechanisms Core provides specialized services related to both human and rodent adipose tissue. Under Dr. Zaghloul’s supervision, the Functional Genomics Sub-Core provides specialized services using zebrafish animal models of disease.
  • Biostatistics and Medical Informatics (BMI) Sub-Core (John Sorkin, MD, PhD, Director). Under Dr. Sorkin’s supervision, the BMI Sub-Core provides services related to biostatistics and database management.
  • Clinical Translational Research (CTR) Core (Alice Ryan, PhD, Director; Elizabeth Streeten, MD, Director of the Amish Research Clinic (ARC) Sub-Core; Dr. Lawrence Appel, MD, Director of JHMI/Pro-Health-based clinical research Sub-Core). Under Dr. Ryan’s supervision, the CTR Core provides specialized services related to nutrition, physical exercise, and clinical chemistry. Under Dr. Streeten’s supervision, the ARC Sub-Core conducts clinical research in the Old Order Amish population of Lancaster, PA. Under the Dr. Appel’s supervision, Pro-Health conducts clinical research related to nutrition and metabolic disease.
  • Community Obesity Measures of Movement, Anthropometry, Nutrition& Diet (COMMAND) (Erin Hager, PhD, Director).  Under Dr. Hager’s supervision, the Field-Based Anthropometric, Dietary, and Physical Activity Assessment Sub-Core provides support for investigators who incorporate anthropometric, dietary/feeding, and physical activity measures into community research protocols.
  • Molecular Genetics and Nutrigenomics (MGN) Core (Braxton Mitchell, PhD, Director; Timothy O’Connor, PhD, Co-Director). Under Dr. Mitchell’s supervision, the MGN Core provides services related to molecular genetics, genetic epidemiology, and functional genomics. Under Dr. O’Connor’s supervision, the MGN Core provides services related to DNA and RNA sequencing.

The Cores provide customized research services as well as consultations and collaborations. Accordingly, this Service Center does not provide a specific price list for routine services. Rather, potential users are invited to provide brief descriptions of their projects as well as their research needs. The appropriate NORC scientist will follow up with the requester in order to agree upon a plan to provide the needed services. The NORC’s prices are intended to cover the cost of providing the services. In selected cases where the requester does not have funding, the NORC may be able to identify sources of funding to cover part or all of the costs.
