National Institute of Standards and Technology Environmental Scan 2023: Societal and Technology Landscape to Inform Science and Technology Research

August 23, 2023
Author(s)
Ashley Boggs-Russell, Kerrianne Buchanan, David W. Griffith, Heather Evans, Dimitrios Meritis, Lisa Ng, Anna Sberegaeva, Michelle Stephens
The 2023 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through three separate lenses

Temporal tends of persistent organic pollutants in Sarasota Bay common bottlenose dolphins (Tursiops truncatus)

John Kucklick, Ashley Boggs-Russell, Kevin Huncik, Amanda Moors, Elizabeth Davis, Gina Ylitalo, Mary McConnell, Christina Makris, Randall Wells
Legacy persistent organic pollutants (POPs) were measured in blubber samples collected from 196 common bottlenose dolphins (Tursiops truncatus) during 2000 to 2016 in the Sarasota Bay, Florida, ecosystem. Legacy POPs included polychlorinated biphenyl

Development of a pregnancy-specific reference material for thyroid biomarkers, vitamin D, and nutritional trace elements in serum

October 24, 2020
Author(s)
Ashley Russell, Lisa Kilpatrick, Carolyn Burdette, Denise S. Tevis, Zachary A. Fultz, Michael Nelson, Jeff M. Jarrett, Stephen A. Wise, Brittany Kassim, Stephen E. Long
Background Concentrations of critical metabolites, hormones, and nutritional elements change significantly throughout pregnancy. Therefore, increased matrix complexity is a challenge for the measurement of these biomarkers. To provide a quality assurance

New Insights into Female Humpback Whale (Megaptera novaeangliae) Reproductive Endocrinology Revealed by Steroid Hormone Profile Analysis

February 19, 2020
Author(s)
Greta Dalle Luche, Ashley Boggs, John Kucklick, Jasmin Gross, Darryl Hawker, Susan Bengston Nash
The blubber steroid hormone profiles of 52 female humpback whales migrating along the east coast of Australia were investigated for possible seasonal endocrinological changes associated with reproduction. Individuals were randomly sampled in southeast

Blubber steroid hormone profiles as indicators of physiological state in free-ranging common bottlenose dolphins (Tursiops truncatus)

December 31, 2019
Author(s)
Thomas M. Galligan, Ashley Boggs, Brian C. Balmer, Teresa Rowles, Cynthia Smith, Forrest Townsend, Randall Wells, Nicholas Kellar, Eric Zolman, Lori Schwacke
Assessing endocrine health in free-ranging marine mammals can be difficult due to limited access to blood samples, which is the most commonly used sample matrix for endocrine assessment in wildlife. Blubber contains steroid hormones and can be collected

Liquid chromatography tandem mass spectrometry for the quantitation of steroid hormone profiles in blubber from stranded humpback whales (Megaptera novaeangliae)

July 30, 2019
Author(s)
Greta Dalle Luche, Susan Bengston Nash, John Kucklick, Fletcher M. Mingramm, Ashley Russell
Marine mammal blubber is known to have quantifiable concentrations of steroid hormones and is increasingly chosen as a matrix for the detection of these reproductive and stress biomarkers. Steroid hormones act through complex cascades, often in concert

Remote blubber sampling paired with liquid chromatography tandem mass spectrometry for steroidal endocrinology in free-ranging bottlenose dolphins (Tursiops truncatus)

June 11, 2019
Author(s)
Ashley S. Boggs-Russell, Jared M. Ragland, Eric Zolman, Tracey B. Schock, Jeanine S. Morey, Thomas M. Galligan, Greta Dalle Luche, Brian C. Balmer, Randall S. Wells, John R. Kucklick, Lori Schwacke
Liquid chromatography tandem mass spectrometry allows for the measurement of steroid hormone suites in the blubber of marine mammals. By combining this technology with minimally invasive techniques such as remote biopsy, endocrine profiles can be assessed

Examining the Relationships Between Blubber Steroid Hormone and Persistent Organic Pollutant Measurements in Common Bottlenose Dolphins

March 24, 2019
Author(s)
Thomas M. Galligan, Brian C. Balmer, Lori Schwacke, Jennie L. Bolton, Brian M. Quigley, Patricia Rosel, Gina M. Ylitalo, Ashley Russell
In this study, we use remotely collected blubber samples from common bottlenose dolphins (Tursiops truncatus) inhabiting the waters near a U.S. Environmental Protection Agency Superfund site with high local DDx concentrations, to study the impacts of DDx

Characterization of Circulating Steroid Hormone Profiles in the Bottlenose Dolphin (Tursiops truncatus) by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS)

July 1, 2018
Author(s)
Thomas M. Galligan, Lori Schwacke, Dorian S. Houser, Randall Wells, Teresa Rowles, Ashley Russell
Circulating steroid hormone concentrations are typically measured by immunoassays, which have imperfect specificity and are limited to the measurement of a single hormone per assay. Here we demonstrate that reverse phase solid phase extraction (SPE)

Evidence for cortisol-cortisone metabolism by marine mammal blubber

June 21, 2018
Author(s)
Thomas M. Galligan, Lori Schwacke, Wayne E. McFee, Ashley Russell
Blubber, a specialized form of adipose tissue in marine mammals, has been identified as a useful matrix for the assessment of steroid hormone homeostasis in cetaceans. However, blubber cortisol measurements are not quantitatively predictive of circulating

Rapid and reliable steroid hormone profiling in Tursiops truncatus blubber using liquid chromatography tandem mass spectrometry (LC-MS/MS)

June 1, 2017
Author(s)
Ashley S. Boggs-Russell, Tracey B. Schock, Thomas M. Galligan, Wayne E. McFee, Jeanine S. Morey, Lori Schwacke, John R. Kucklick
Monitoring of marine mammal steroid hormone status using matrices alternative to blood is desirable due to the ability to remotely collect samples which minimizes stress. However, measurement techniques in alternative matrices such as blubber described to

Integrative and comparative reproductive biology: From alligators to xenobiotics
