NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2016 Comparability Studies: Results for Round Robin LXXIX and LXXX Fat-Soluble Vitamins and Carotenoids in Human Serum

March 16, 2017
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-soluble vitamins and carotenoids in human serum and plasma. This report describes the design

Enhancing the Efficacy of Cancer Therapy: Use of Small Molecule Inhibitors of DNA Glycosylases as Potential Drugs

March 12, 2017
Author(s)
Erdem Coskun, Aaron C. Jacobs, Nathan Donley, Marcus J. Calkins, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Pawel Jaruga, Amanda K. McCullough, M Miral Dizdar, R. S. Lloyd
Chemotherapy aims to destroy cancer cells by damaging their DNA. However, the overexpression of DNA repair proteins in cancer cells causes the removal of DNA lesions before they become toxic and thus leads to an increased DNA repair capacity resulting in

Experimental and statistical methods to evaluate antibacterial activity of a quaternary pyridinium salt on planktonic, biofilm-forming, and biofilm states

March 3, 2017
Author(s)
Daneli Lopez-Perez, Paula J. Baker, Adam L. Pintar, Jirun Sun, Nancy Lin, Sheng Lin-Gibson
Robust evaluation and comparison of antimicrobial technologies are critical to improving biofilm prevention and treatment. Herein, a multi-pronged experimental framework and statistical models were applied to determine the effects of quaternary pyridinium

FDA Approves First Genetically-Modified Cell Therapy to Treat Leukemia

March 1, 2017
Author(s)
Carl Simon Jr.
The FDA approved the first genetically-modified cell therapy for the treatment of leukemia on August 30, 2017 [1-2]. The treatment (tisagenlecleucel) is an "autologous genetically modified immunocellular therapy indicated for the treatment of pediatric and

Performing Skin Microbiome Research: A Method to the Madness

March 1, 2017
Author(s)
Heidi H. Kong, Bjorn Andersson, Thomas Clavel, John E. Common, Scott Jackson, Nathanael David Olson, Julia Segre, Claudia Traidl-Hoffman
Growing interest in microbial contributions to human health and disease has increasingly led investigators to examine the microbiome in both healthy skin and cutaneous disorders, including acne, psoriasis, and atopic dermatitis. The need for common

Measurements of translation initiation from all 64 codons in E. coli

February 21, 2017
Author(s)
Ariel H. Hecht, Jeff E. Glasgow, Paul Jaschke, Lukmaan Bawazer, Matthew S. Munson, Jennifer R. Cochran, Drew Endy, Marc L. Salit
Our understanding of translation represents a cornerstone of molecular biology and underpins our capacity to engineer living matter. For decades, the codon AUG and a few near-cognates (GUG, UUG) have been exclusively considered as “start codons” for

Extracting Two Parameters From a P2 Orientation Distribution

February 19, 2017
Author(s)
Curtis Meuse, Joseph B. Hubbard
Individual molecules are seldom identical. This poses a problem for optical spectroscopy. For instance, if molecular property distributions are not characterized, differences in the distribution of molecular properties between sample and standards are

Structural Calcium (Trypsin, Subtilisin)

February 19, 2017
Author(s)
G L. Gilliland, A Teplyakov
There are about 40 families of serine proteases defined by amino acid sequence similarities that can be further grouped into 7 clans on the basis of their tertiary structure and the order of the catalytic triad. 1 Members of clans SA and SB are
