NIST Micronutrients Measurement Quality Assurance Program Winter 2015 Comparability Studies: Results for Round Robin LXXVII Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 42 Ascorbic Acid in Human Serum

July 28, 2016
Author(s)
Jeanice M. Brown Thomas, David L. Duewer
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes

A New Molecular Model for Lithium's Biological Interactions

July 25, 2016
Author(s)
John Marino, Katharine T. Briggs, Gary G. Giulian, Joe Kao, Gong Li
Lithium carbonate, a drug for the treatment of Bipolar Disorder, provides mood stability to mitigate recurrent episodes of mania and/or depression. Despite its long term and widespread use, the mechanism by which lithium acts to elicit these psychological

Standards for cell line authentication and beyond

Jamie L. Almeida, Kenneth D. Cole, Anne L. Plant
Different genomic technologies have been applied to cell line authentication, but only one method (short tandem repeat profiling) has been the subject of a comprehensive standard (ASN-0002). Here we discuss the power of this document, and why standards

Wide-field quantitative imaging of tissue microstructure using high-frequency structured light

David McClatchy III, Elizabeth Rizzo, wendy wells, Jeeseong C. Hwang, keith paulson, Brian Pogue, Stephen Kanick
Sub-diffusive structured light imaging has been shown to accurately and quantitatively map the reduced scattering coefficient and the phase function backscatter parameter in a wide-field geometry. This study shows the first the experimental imaging of

Extensive sequencing of seven human genomes to characterize benchmark reference materials

June 7, 2016
Author(s)
Justin M. Zook, Jennifer H. McDaniel, David N. Catoe, Lindsay Harris, Marc L. Salit
The Genome in a Bottle Consortium hosted by the National Institute of Standards and Technology, (NIST), is creating reference materials and data for human genome sequencing, as well as methods for genome comparison and benchmarking. Here, we describe a

Measurement of DNA repair protein apurinic/apyrimidinic endonuclease 1 (APE1) in human tissues by liquid chromatography/tandem mass spectrometry with isotope dilution

June 5, 2016
Author(s)
Pawel Jaruga, Guldal Kirkali, Prasad T. Reddy, Alessandro Tona, Bryant C. Nelson, Li Mengxia, David M. Wilson III, Erdem Coskun, M Miral Dizdar
Introduction DNA repair proteins may be used as biomarkers in disease etiology and therapy. Thus, the accurate determination of DNA repair protein expression and genotype in human tissues is of fundamental importance. Apurinic/apyrimidinic endonuclease 1
