  • Superfund Researcher Discovers Promising Method to Assist Vitamin C in Killing Cancer Cells

    March 16, 2017

    Dr. Garry Buettner, Co-Leader of Project 1 of the Iowa Superfund Research Program, published a report in the December 2016 edition of Redox Biology that demonstrated that high doses of Vitamin C given intravenously are much more effective in killing cancer cells than oral medications of Vitamin C.

    Researchers have shown that Vitamin C breaks down easily- creating hydrogen peroxide. Cancer cells have a decreased ability to process hydrogen peroxide. Giving Vitamin C intravenously creates blood levels 100 to 500 times higher of Vitamin C.

    Current Superfund Research trainee Visarut Buranasudja and former trainee Claire Doskey assisted with the research.

  • ISRP Trainees Graduate!

    January 04, 2017

    3 isrp trainees completed their requirements in the fall of 2016. They are:

    Marisa Beltran Salomon completed her M.S. degree. Her thesis was entitled "Novel Tools for Targeting PCBs and PCB Metabolites Using ssDNA Aptamers." Pictured are her thesis committee Dr. Hans Joachim Lehmler, Dr. Gabriele Ludewig(mentor), and Dr. Garry Buettner.





    Gopi Gadupudi completed the requirements for his PhD degree. His thesis was entitled "PCB126-Induced Metabolic Disruption: Effects on Liver Metabolism And Adipocythe Development." Pictured are his thesis committee Dr. Katherine Gibson-Corley, Dr. Aloysius J Klingelhutz, Dr. Larry Roberton(mentor), Dr. Gabriele Ludewig, and Dr. Justin Grobe.




    Taehyun Roh completed his PhD degree. His thesis was entitled "Exposure to Arsenic and Atrazine from Drinking Water and Risk of Cancer." Pictured are his thesis committee Dr. Charles Lynch, Dr. Larry Robertson, Dr. Gabriele Ludewig, Dr. Kevin Kelley, and Dr. Kai Wang.

  • Miao Li gives KC Donnelly Talk at Superfund Research Program Conference!

    December 30, 2016


    Miao Li, University of Iowa Superfund Research Program trainee and recent graduate, gave an oral presentation about his KC Donnelly Externship experience at the Superfund Research Program National Conference in Durham, NC. While at the University of Iowa, he investigated the mechanism of toxicity of airborne PCBs through their metabolic activation and the resultant formation of protein adducts.

    This project required extremely sensitive detection methods. During the externship in the laboratory of Dr. Nakamura at UC Berkeley, Li had the opportunity to use state-of-the-art techniques and equipment to identify the profile of the target proteins of PCB metabolite reactivity. Publications of the results of this fruitful collaboration are currently in preparation.

    Miao is currently a post-doctoral fellow at Kansas State University.

  • Iowa and BU Superfunds Present at SETAC

    December 22, 2016

    Dr. Andres Martinez from the University of Iowa Superfund Research Program and Dr. Wendy Heiger-Bernays of the Boston University Superfund Research Program co-presented a session on airborne PCBS at New Bedford Harbor at the Society of Environmental Toxicology and Chemistry meeting in Orlando in November 2016. Their poster entitled "Continuous release of PCBs from New Bedford Harbor results in elevated concentrations in the surrounding air" documents the result of recent air monitoring and shows that this legacy contamination is still of concern for neighboring communities. New Bedford Harbor is a major source of airborne PCBs.

  • ISRP at the NIEHS Science Fest

    December 20, 2016

    In early December 2016 members of the isrp participated in the NIEHS Environmental Health Sciences FEST in Durham, North Carolina. Over 1200 people attended the first ever sciences FEST, twelve from the isrp.

    As part of its 50th anniversary celebration, the National Institute of Environmental Health Sciences (NIEHS) hosted researchers, trainees, young investigators, community partners, and stakeholders from across the United States. Over 1200 participants discussed accomplishments and explored the future of environmental health science.

  • Community Engagement in Schools

    December 19, 2016

    On Wednesday, October 26th, Ashlee Johannes(below right), Marisa Salomon Beltran(below left), and Eric Uwimana of the University of Iowa SRP (ISRP) traveled to East Chicago, Indiana to engage eighth grade students at Joseph L Block Jr High school in learning about polychlorinated biphenyls (PCBs). During this full day of events supported by the Community Engagement Core of the ISRP, students were instructed how to teach their classmates about PCBs in a team-building environment. One highlight of the event was when the students were asked to build their own PCB molecule using molecular model kits. The students were excited when they got to take their molecule home to show their families and friends.

    For isrp graduate students these community engagement opportunities with junior high school students are extremely rewarding and eye-opening. It exemplifies how their training and research can be a benefit in the lives of others. Thank you to Joseph L Block Jr High School’s principal, teachers, and staff for this collaborative effort of educating students about potential health concerns within their community and teaching graduate trainees about the importance of service to the community.
