Coon Research Group BenefieldApril 20, 2022, CEG-hosted DEPHS Wednesday Seminar: Cryo Electron Microscopy: CryoEM Capabilities at UC, presented by Desiree A. Benefield, PhD; Research Scientist; UC Cardiovascular Research Center. Dr. Benefield has used advanced Cryo-em techniques to advance understanding of positive-strand RNA virus genome replication mechanisms. This seminar will feature CryoEM core facility services coming available as of July 2022.  Before April's seminar, students and trainees, especially, may enjoy this brief interview that Dr. Benefield provided early in her scientific career: Virus Host Interactions. 10:00 AM Kettering Kehoe Auditorium (G26). 

Dr. Benefield's talk is designed to highlight yet another new resource at UC and CCHMC and is part of lecture series organized by the CEG Integrative Technologies Support (ITS) Core, led by Ying Xia, PhD. Co-leader: Ranjan Deka, PhD. In March, the ITS Core hosted a seminar on Highly efficient CRISPR editing and inducible CRISPRi/a/ko services. Presented by Dr. Yueh-Chiang Hu, director of the Transgenic and Genome Editing Core, Cincinnati Children's Hospital Medical Center (CCHMC), March 30th.

In collaboration with the Pluripotent Stem Cell Facility at CCHMC, it has also established streamlined hiPS cell gene editing services. The core's services are in such high demand that Dr. Hu and colleagues have tripled the size of their team since 2013. The TAGE core has completed hundreds of genome editing projects, at a pace of one per week, with few failures.

In January, the CEG and its ITS Core hosted Andrea A. Baccarelli MD, PhD, the Leon Hess Professor and Chair of the Department of Environmental Health Sciences, Columbia University and Director of both the Laboratory of Precision Environmental Biosciences and the Columbia Center for Environmental Health in Northern Manhattan. This and other previously recorded seminars may be viewed courtesy of the DEPHS Graduate Office.

Portrait of Xiang Zhang PhDThe Genomics and Epigenomics Sequencing Core (GESC), managed by Xiang Zhang, PhD, has updated its online form for requesting services: CEG investigators who use GESC services should self-identify as CEG members, in order to enhance Center reporting of research productivity. CEG members also should indicate on the form whether they would additionally like their data to be transferred to the CEG Bioinformatics Core (Director: Mario Medvedovic, PhD). The Bioinformatics Core offers long-term data storage, as well as options for highly sophisticated data analysis.

Integrative Technologies Support (ITS) Core Funding Available: CEG members are eligible for ITS Subsidies (i.e., matching funds) for use of certain cores and services, including Bioinformatics support. PIs with currently funded CEG Pilot awards may receive pro bono Bioinformatics support for the CEG-funded project. Details and an application form can be obtained on the ITS Core Web page.

    The Application Submission System & Interface for Submission Tracking (ASSIST) system is used to submit applications electronically to NIEHS and other NIH and Public Health Service agencies. It is also used to ensure PIs' compliance with timely reporting of Human Subjects Study inclusion enrollment data, etc. Delays and errors in Human Subjects reporting via ASSIST can delay or jeopardize individual and Center funding; hence, this guidance on Navigating ASSIST for Human Subjects and Clinical Trials, presented by NIEHS staff specialist Martha Barnes, M.S. is important for PIs and their staff: PPT slides accessible here (PDF). Webinar recording accessible here (mp4 file).

    Yolton, Cecil, Ryan Team earns $5 million NIEHS R01 Award

    Kim Yolton Kim Cecil Patrick Ryan CCHMCCEG Internal Advisory Board member Kimberly Yolton, PhD, Professor and  Director of Research Section, General and Community Pediatrics, Cincinnati Children’s Hospital Medical Center, and fellow CEG members Patrick H. Ryan, PhD, MS, Professor of Pediatrics, and Kim Cecil, PhD, Professor in the Department of Radiology, have received a new 5-year NIEHS R01 award: Longitudinal Impact of Air Pollution on Mental Health and Neuroimaging Outcomes during Adolescence in the Cincinnati Combined Childhood Cohorts (C4). R01 ES031621. Co-PI Patrick H. Ryan, PhD, MS, Professor of Pediatrics, and co-investigator Kim Cecil, PhD, are also CEG members. Project start-end 3/3/2021–12/31/2025, total 2021 funding $1.1 million.

    The team will use existing longitudinal data from the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS) and the Health Outcomes and Measures of the Environment (HOME) Study to address the hypothesis that exposure to air pollution during critical periods of brain development, including adolescence, is associated with adverse mental health outcomes.

    Both prospective cohorts have been followed from birth and evaluated with concordant measures of mental health and neuroimaging at age 12 years. The team will conduct new follow-up at age 18 years to assess the onset and persistence of mental health outcomes through adolescence and apply validated models for PM2.5 and TRAP to characterize air pollution exposure from conception through age 18 years. The team also will acquire novel neuroimaging outcomes, including brain-aminobutyric acid and glutathione concentrations accompanied by anatomical and functional magnetic resonance imaging.
