Hydration of Hydrophilic Cloth Facial Coverings Greatly Increases the Filtration Properties for Nanometer and Micrometer-sized Particles

March 8, 2021
Author(s)
Christopher Zangmeister, James Radney, Matthew Staymates, Edward P. Vicenzi, Jamie Weaver
Filtration efficiencies (FE) of natural, synthetic, and blended fabrics were measured as a function of relative humidity (RH) for particles with mobility diameters between 50 nm and 825 nm. Fabrics were equilibrated at 99 % RH, mimicking conditions

Towards Quantitative and Standardized Serological and Neutralization Assays for COVID-19

March 8, 2021
Author(s)
Linhua Tian, Elzafir B. Elsheikh, Paul Patrone, Anthony Kearsley, adolfas Gaigalas, Sarah L. Inwood, Sheng Lin-Gibson, Dominic Esposito, Lili Wang
Quantitative and robust serology assays are critical measurements underpinning global COVID-19 response to diagnostic, surveillance, and vaccine development. Here, we report a proof-of-concept approach for the development of quantitative, multiplexed flow

National Institute of Standards and Technology Environmental Scan 2020

February 9, 2021
Author(s)
Heather Evans, Kristen K. Greene, William M. Healy, Elizabeth Hoffman, Kate Rimmer, Anna V. Sberegaeva, Neil M. Zimmerman
The 2020 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 four separate lenses

Chromosome-scale, haplotype-resolved assembly of human genomes

December 7, 2020
Author(s)
Justin Zook, Shilpa Garg, Heng Li
Haplotype-resolved or phased genome assembly provides a complete picture of genomes and their complex genetic variations. However, current algorithms for phased assembly either do not generate chromosome-scale phasing or require pedigree information, which

Chapter 4: Oxidatively induced DNA damage: Mechanisms and measurement

November 20, 2020
Author(s)
Miral M. Dizdar, Erdem Coskun, Gamze Tuna, Melis Kant, Pawel Jaruga
Oxidatively induced damage to DNA occurs in living organisms by endogenously or exogenously generated reactive species including free radicals. Mounting evidence suggests that this type of DNA damage plays an important role in the etiology of numerous

A Case Study of Medical Device Wireless Coexistence Evaluation

October 1, 2020
Author(s)
Mohamed Al-Kalaa, Joshua Guag, Seth Seidman, Yao Ma, Jason Coder
This article aims to provide a narrative for addressing wireless coexistence in medical devices to help medical device developers, test engineers, and regulatory affairs personnel throughout the device life cycle. Accordingly, we present a case-study

A NIST-Hosted Virtual Workshop on Measuring SARS-CoV-2 in Wastewater and Fecal Material: A Call for Standards

September 28, 2020
Author(s)
Sandra M. Da Silva, Paulina K. Piotrowski, Christina M. Jones, Stephanie L. Servetas, Nancy J. Lin, Katrice A. Lippa, Scott A. Jackson
The National Institute of Standards and Technology (NIST) has leveraged its expertise in chemical and biological metrology and standards development as well as its strong relationships with stakeholders to host a virtual workshop on June 16, 2020 that

A Diploid Assembly-based Benchmark for Variants in The Major Histocompatibility Complex

September 22, 2020
Author(s)
Justin M. Zook, Justin M. Wagner, Chen-Shan Chin, Qiandong Zeng, Alexander Dilthey, Tobias Marschall, Mikko Rautiainen, Erik Garrison, Shilpa Garg
Most human genomes are characterized by aligning individual reads to the reference genome, but accurate long reads and linked reads now enable us to construct accurate, phased de novo assemblies. We focus on a medically important, highly variable, 5

THE GUT MICROBIOME AND XENOBIOTICS: IDENTIFYING KNOWLEDGE GAPS

Vicki L. Sutherland, Charlene A. McQueen, donna Mendrick, donna gulezian, Carl Cerniglia, Steven Foley, Samuel Forry, Sangeeta Khare, Xue Liang, Jose E. Manautou, Donald Tweedie, howard young, Alexander Aleksenkyo, frank burns, Rod Dietert, Katherine Karberg, alan wilson, connie chen
There is an increasing awareness that the gut microbiome plays a critical role in human health and disease, but mechanistic insights are often lacking. In June 2018, the Health and Environmental Sciences Institute (HESI) held a workshop, "The Gut

Improving patient outcomes with regenerative medicine: How to move the needle forward in cell manufacturing, standards, 3D bioprinting, AI enabled automation, education and training

June 17, 2020
Author(s)
Carl Simon, Josh Hunsberger, Claudia Zylberberg, Preveen Ramamoorthy, Thomas Tubon, Crystal Ruff, Ram Bedi, Kurt Gielen, Lynn Fisher, Jed Johnson, Priya Barankiak, Behzad Mahdavi, Michael Hadjisavas, Shannon Eaker, Cameron Miller
Regenerative Medicine Manufacturing Society (RMMS), is the first and only professional society dedicated specifically towards advancing manufacturing solutions for the field of regenerative medicine. RMMS' vision is to provide greater patient access to

Expression of a germline variant in the N-terminal domain of the human DNA glycosylase NTHL1 induces cellular transformation without impairing enzymatic function or substrate specificity

June 16, 2020
Author(s)
Carolyn G. Marsden, Pawel Jaruga, Erdem Coskun, Robyn L. Maher, David S. Pederson, Miral M. Dizdar, Joann B. Sweasy
Oxidatively-induced DNA damage, widely accepted as a key player in the onset of cancer, is predominantly repaired by base excision repair (BER). BER is initiated by DNA glycosylases, which locate and remove damaged bases from DNA. NTHL1 is a bifunctional

A robust benchmark for detection of germline large deletions and insertions

June 15, 2020
Author(s)
Justin Zook, Nathanael David Olson, Marc Salit, Fritz Sedlazeck
New technologies and analysis methods are enabling genomic structural variants (SVs) to be detected with ever-increasing accuracy, resolution and comprehensiveness. To help translate these methods to routine research and clinical practice, we developed a

Structural basis for oligoclonal T cell recognition of a shared p53 cancer neoantigen

June 9, 2020
Author(s)
David Gallagher, Roy A. Mariuzza, Brian G. Pierce, Daichao Wu, Ragul Gowthaman
Abstract Adoptive cell therapy (ACT) with tumor-specific T cells can mediate cancer regression. The main target of tumor-specific T cells are neoantigens arising from mutations in self-proteins. Although the majority of cancer neoantigens are unique to

Assembly and annotation of an Ashkenazi human reference genome
