AI Assurance for the Public -- Trust but Verify, Continuously

October 3, 2022
Author(s)
Phillip Laplante, D. Richard Kuhn
Artificial intelligence (AI) systems are increasingly seen in many public facing applications such as self-driving land vehicles, autonomous aircraft, medical systems and financial systems. AI systems should equal or surpass human performance, but given

Report from the NIST Workshop: Launch of the Rapid Microbial Testing Methods Consortium

September 27, 2022
Author(s)
Nancy Lin, Scott Jackson, Stephanie Servetas, Kirsten Parratt, Joy Dunkers, Tara Eskandari, Sheng Lin-Gibson
On September 17, 2020, NIST hosted a virtual workshop to launch the Rapid Microbial Testing Methods (RMTM) Consortium. The RMTM Consortium aims to address the need for measurements and standards to increase confidence in the use of rapid testing for

Certification of Standard Reference Material(R) 915c Calcium Carbonate

September 20, 2022
Author(s)
Thomas W. Vetter, Jason Waters, Adam L. Pintar
Standard Reference Material (SRM) 915c Calcium Carbonate is certified as a chemical substance of known purity. It is intended for use in the calibration and standardization of procedures for calcium (Ca) determinations employed in clinical analysis and for

Report on the DHS/NIST Workshop on Standards for an Enduring Capability in Wastewater Surveillance for Public Health (SWWS Workshop)

August 16, 2022
Author(s)
Nancy Lin, Stephanie Servetas, Scott Jackson, Katrice Lippa, Kirsten Parratt, Philip Mattson, Clare Beahn, Mia Mattioli, Sally Gutierrez, Michael Focazio, Ted Smith, Paul Storella, Sarah Wright
Wastewater surveillance is a promising approach to monitor biological and chemical contaminants on a community level in support of public health and safety decisions. Wastewater surveillance has recently been shown highly effective for the early detection

Levels and profiles of perfluorinated alkyl acids in liver tissues of birds with different habitat types and trophic levels from an urbanized coastal region of South Korea

August 1, 2022
Author(s)
Sang Hee Hong, Jessica L. Reiner, Mi Jang, Stacy Schuur, Gi Myung Han, John Kucklick, Won Joon Shim
Contamination status and characteristics of perfluorinated alkyl acids (PFAAs) including perfluorinated carboxylic acids (PFCAs) and perfluorinated sulfonic acids (PFSAs) was examined using liver tissue of birds - blacktailed gulls (Larus crassirostris)

Polymorphic variant Asp239Tyr of human DNA glycosylase NTHL1 is inactive for removal of a variety of oxidatively-induced DNA base lesions from genomic DNA

July 16, 2022
Author(s)
Melis Kant, Victoria Quintana, Erdem Coskun, Pawel Jaruga, R. Stephen Lloyd, Joann Sweasy, Miral M. Dizdar
Base excision repair is the major pathway for the repair of oxidatively-induced DNA damage with DNA glycosylases removing modified DNA bases in the first step. Among them, human NTHL1 is specific for excision of several pyrimidine- and purine-derived

Technical Framework for High Quality New Approach Methodologies (NAMs)

July 15, 2022
Author(s)
Elijah Petersen, John T. Elliott, John Gordon, Nicole Kleinstreuer, Emily Reinke, Matthias Roesslein, Blaza Toman
New approach methodologies (NAMs) are in vitro, in chemico, and computational approaches that can potentially be used to reduce animal testing. For NAMs that require laboratory experiments, it is critical that they provide consistent and reliable results

Computational Study of the Allosteric Effects of p5 on the CDK5-p25 Hyperactivity as Alternative Inhibitory Mechanisms in Neurodegeneration

June 30, 2022
Author(s)
Tejaswi Tammareddy, Walid Keyrouz, Ram D. Sriram, Harish C. Pant, Antonio Cardone, Jeffery B. Klauda
The cyclin-dependent kinase (CDK5) forms a stable complex with its activator p25, leading to the hyperphosphorylation of tau proteins and to the formation of plaques and tangles that are considered to be one of the typical causes of Alzheimer's disease (AD
