1. Assessment of Crude Oil and a Dispersant in a Simulated Spartina alterniflora Salt Marsh Ecosystem
Published: 12/1/2014
Authors: P Key, K Chung, C Cooksey, DeLorenzo M, M Fulton, D Greenfield, T Greig, J Hylund, Bryant C Nelson, Varun Patel, P Pennington, Elijah J Petersen, E Wirth
Abstract: NOAA‰s Environmental Sensitivity Index (ESI) lists saltmarshes along the Atlantic and Gulf Coasts as the most vulnerable habitat to oil spills. As a result of the Deepwater Horizon offshore drilling rig accident, more that 200 million gallons of cr ...

2. The DNA Damaging Potential of Photoactivated P25 Titanium Dioxide Nanoparticles
Published: 9/30/2014
Authors: Elijah J Petersen, Vytautas Reipa, Stephanie S Watson, Deborah L Stanley, Savelas A Rabb, Bryant C Nelson
Abstract: Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well known that photoactivated ...

3. Using Single Particle ICP-MS as a Tool for Understanding Metallic Nanoparticle Transformation during Nanotoxicity Assays
Published: 7/1/2014
Authors: Monique Erica Johnson, Shannon Hanna, Antonio Rafael Montoro Bustos, Bryant C Nelson, Elijah J Petersen, Lee Lijian Yu
Abstract: The advent of engineered nanoparticles (ENPs) and their increased use has remarkably improved the performance of basic materials and consumer products, but has also increased the potential for ENP release into the environment. Technical procedure ...

4. Quantitative Assessment of Nanoparticle Induced Oxidative Damage to DNA Using Isotope Dilution Mass Spectrometry
Published: 6/16/2014
Authors: Elijah J Petersen, Pawel Jaruga, M Miral Dizdar, Bryant C Nelson
Abstract: Mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of oxygen-derived free radicals on the induction and subsequent repair of oxidatively-induced DNA damage in living systems. The Natio ...

5. Development of a Standard Reference Material for Metabolomics Research
Published: 11/4/2013
Authors: Karen W Phinney, Guillaume Ballihaut, Mary Bedner, Johanna Camara, Steven J Christopher, William C Davis, Nathan G. Dodder, Brian E Lang, Stephen E Long, Mark S Lowenthal, Elizabeth A. McGaw, Karen E Murphy, Bryant C Nelson, Jocelyn L. Prendergast, Jessica L Reiner, Catherine A Rimmer, Lane C Sander, Michele M Schantz, Katherine E Sharpless, Lorna Tregoning Sniegoski, Susan Shu Cheng Tai, Jeanice M Brown Thomas, Thomas W Vetter, Michael James Welch, Stephen A Wise, Laura J Wood, William F Guthrie, Robert Charles Hagwood, Stefan D Leigh, James H Yen, Nien F Zhang, Madhu Chaurhary-Webb, Huiping Chen, Bridgette Haynes, Donna J LaVoie, Leslie F McCoy, Shahzad S Momin, Neelima Paladugula, Elizabeth C Pendergrast, Christine M Pfeiffer, Carissa D Powers, Zia Fazili-Qari, Daniel Rabinowitz, Michael E Rybak, Rosemary L Schleicher, Mary Xu, Mindy Zhang, Arthur L Castle, Brandi S Benford, Gauthier Eppe

6. Functionalization-Dependent Induction of Cellular Survival Pathways by CdSe Quantum Dots in Primary Normal Human Bronchial Epithelial Cells
Published: 9/5/2013
Authors: Amber Nagy, Jennifer A Hollingsworth, Bin Hu, Andrea Steinbruck, Peter C. Stark, Cristina Rios Valdez, Momchilo Vuyisich, Michael H. Stewart, Donald H Atha, Bryant C Nelson, Rashi Iyer
Abstract: Quantum dots (QDs) are semiconductor nanocrystals exhibiting unique optical properties which can be exploited for many practical applications ranging from photovoltaics to biomedical imaging and drug delivery. They are increasingly manufactured in la ...

7. Identification and Quantification of DNA Repair Protein Apurinic/Apyrimidinic Endonuclease 1 (APE1) in Human Cells by Liquid Chromatography/Isotope-Dilution Tandem Mass Spectrometry
Published: 7/29/2013
Authors: Guldal Kirkali, Pawel Jaruga, Prasad T Reddy, Alessandro Tona, Li Mengxia, David M. Wison III, M Miral Dizdar, Bryant C Nelson
Abstract: Unless repaired, DNA damage can drive mutagenesis or cell death. DNA repair proteins may therefore be used as biomarkers in disease detection or therapeutic response estimation. Thus, the accurate measurement of DNA repair protein expression is of fu ...

8. Oxidatively Induced Damage to DNA: Potential Role of Single-Wall Carbon Nanotubes at the Molecular Level
Published: 5/13/2013
Authors: Elijah J Petersen, Xiaomin X. Tu, M Miral Dizdar, Ming Zheng, Bryant C Nelson
Abstract: Ultrasonication is a physical process known to generate abundant levels of oxygen-derived species such as hydroxyl radicals, hydrogen atoms, and hydrogen peroxide. When used to process DNA solutions, these highly reactive hydroxyl radicals can react ...

9. Tools and Approaches for the Assessment of Nanomaterial Induced Oxidative DNA Damage
Published: 5/13/2013
Authors: Elijah J Petersen, Bryce Marquis, Pawel Jaruga, M Miral Dizdar, Bryant C Nelson
Abstract: Hyphenated mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens, and oxygen derived free radicals on the induction and subsequent r ...

10. Active Transcriptomic and Proteomic Reprogramming in the C. elegans Nucleotide Excision Repair Mutant xpa-1
Published: 4/10/2013
Authors: Katarzyna Arczewska, Gisele Tomazella, Jessica Lindvall, Henok Kassahun, Silvia Maglioni, Alessandro Torgovnick, Johan Henriksson, Olli Matilainen, Bryce J. Marquis, Bryant C Nelson, Eshrat Babaie, Carina Holmberg, Thomas Burglin, Natascia Ventura, Bernd Thiede, Hilde Nilsen
Abstract: Transcription-blocking oxidative DNA damage is believed to contribute to aging and to underlie activation of oxidative stress-responses and down-regulation of insulin-like signaling (ILS) in Nucleotide Excision Repair (NER) deficient mice. Here, we p ...
