Urine Proteomics in the Era of Mass Spectrometry

November 22, 2016
Author(s)
Ashley B. Green
With the technological advances of mass spectrometry (MS)-based platforms, clinical proteomics is one of the most rapidly growing areas in biomedical research. Urine proteomics has become a popular sub-discipline of clinical proteomics because it is an

Alterations in eicosanoid composition during embryonic development in the chorioallantoic membrane of the American alligator (Alligator mississippiensis) and domestic chicken (Gallus gallus)

November 1, 2016
Author(s)
John Bowden, Theresa M. Cantu, Jacob Scott, Jimena B. Perez-Viscasillas, Kevin M. Huncik, Matthew P. Guillette, Louis J. Guillette Jr.
Eicosanoids are signaling lipids that regulate several physiological processes in the mammalian placenta, including the initiation of parturition. Though all amniotes construct similar extraembryonic membranes during development, the composition and

Development and Characterization of Reference Materials for Genetic Testing

November 1, 2016
Author(s)
Justin M. Zook, Marc L. Salit, Lisa V. Kalman, Mickey Williams, Vivekananda Datta, Jin-Yeong Han
Characterized reference materials (RM) are needed for test development and validation, quality control procedures and proficiency testing to assure the quality of clinical laboratory tests. In this article, we review the development and characterization of

Integrative and comparative reproductive biology: From alligators to xenobiotics

November 1, 2016
Author(s)
Ashley S. Boggs-Russell, John Bowden, Abby G. Wenzel, Satomi Kohno, Heather J. Hamlin, Lori Cruze, Krista A. McCoy, Alison M. Roark, Thea M. Edwards, Theresa M. Cantu, Jessica A. Cloy-McCoy, Nicole A. McNabb, Cameron E. Williams
Dr. Louis J. Guillette Jr. thought of himself as a reproductive biologist. However, his interest in reproductive biology transcended organ systems, life history stages, species, and environmental contexts. His integrative and collaborative nature led to

Enhanced Sensitivity of Neil1-/- Mice to Chronic UVB Exposure

October 28, 2016
Author(s)
Pawel Jaruga, M Miral Dizdar, Marcus J. Calkins, Vladimir Vartanian, Amanda McCullough, R. S. Lloyd, Guldal Kirkali
Oxidative stress and oxidatively induced DNA base damage are central mediators of UV-induced carcinogenesis and skin aging. However, increased steady-state levels of oxidatively induced DNA base damage have not been reported after chronic UV exposure

Toward Achieving Harmonization in a Nano-cytotoxicity Assay Measurement through an Interlaboratory Comparison Study

September 29, 2016
Author(s)
John T. Elliott, Matthias Roesslein, Nam W. Song, Blaza Toman, Agnieszka Kinsner-Ovaskainen, Rawiwan Maniratanachote, Marc L. Salit, Elijah J. Petersen, Fatima Sequeira, Jieun Lee, Francois Rossi, Cordula Hirsch, Harald Krug, Wongsakorn Suchaoin, Peter Wick
Design and development of reliable cell-based nanotoxicology assays is important for ranking of potential hazardous engineered nanomaterials. Challenges to producing a reliable assay protocol include working with nanoparticle dispersions and living cell

Elevated urinary levels of 8-hydroxy-2’-deoxyguanosine, (5’R)- and (5’S)-8,5’-cyclo-2’- deoxyadenosines, and 8-iso-prostaglandin F2? as potential biomarkers of oxidative stress in patients with prediabetes

September 26, 2016
Author(s)
M Miral Dizdar, Melis Kant, Merve Akis, Mehmet Calan, Tugba Arkan, Firat Bayraktar, Huray Islekel
Prediabetes is the preclinical stage of type 2 diabetes mellitus with intermediate state of hyperglycemia. Hyperglycemia results in a state of oxidative stress and that reactive oxygen species contribute to the production of insulin resistance, β-cell

After oxidation, zinc nanoparticles lose their ability to enhance responses to odorants

September 20, 2016
Author(s)
Samantha Hagerty, Yasmine C. Daniels, Melissa Singletary, Oleg Pustovyy, Ludmila Globa, William A. MacCrehan, Shinichiro Muramoto, June W. Lau, Edward Morrison, Iryna Sorokulova, Vitaly Vodyanoy, Gheorghe Stan
Electrical responses of olfactory sensory neurons to odorants were examined in the presence of zinc nanoparticles of various sizes and degrees of oxidation. The zinc nanoparticles were prepared by the underwater electrical discharge method and analyzed by
