Liver proteome response to torpor in a basoendothermic mammal, Tenrec ecaudatus, provides insights into the evolution of homeothermy

October 6, 2021
Author(s)
Jane Khudyakov, Michael Treat, Mikayla Shanafelt, Jared Deyarmin, Ben Neely, Frank van Breukelen
Many mammals use adaptive heterothermy (e.g., torpor, hibernation) to reduce metabolic demands of maintaining high body temperature (Tb). Torpor is typically characterized by coordinated declines in Tb and metabolic rate (MR) followed by active rewarming

Quantitative Craniofacial Analysis and Generation of Human Induced Pluripotent Stem Cells for Muenke Syndrome: A Case Report

In this case report, we focus on Muenke syndrome (MS), a disease caused by the p.Pro250Arg variant in fibroblast growth factor receptor 3 (FGFR3) and characterized by uni- or bilateral coronal suture synostosis, macrocephaly without craniosynostosis

Characteristics to Consider when Selecting a Positive Control Material for an In Vitro Assay

September 29, 2021
Author(s)
Elijah Petersen, Andrew Nguyen, Jeffrey Brown, John Elliott, Amy Clippinger, John Gordon, Nicole Kleinstreuer, Matthias Roesslein
The use of in vitro assays to inform decision-making requires robust and reproducible results across studies, laboratories, and time. Experiments using positive control materials are an integral component of an assay procedure to demonstrate the extent to

Resources for developing reliable and reproducible in vitro test methods

September 29, 2021
Author(s)
Elijah Petersen, Vytas Reipa, Menghang Xia, Monita Sharma
A broad range of in vitro test methods have been developed given their numerous potential advantages over in vivo tests. We describe here key resources and tools to increase the reliability and reproducibility of in vitro test methods.

Use of cause-and-effect analysis to optimize the reliability of in vitro inhalation toxicity measurements using an air-liquid interface

September 29, 2021
Author(s)
Elijah Petersen, Monita Sharma, Amy Clippinger, John Gordon, Aaron Katz, Peter Laux, Lars Leibrock, Andreas Luch, Joanna Matheson, Andreas Stucki, Jutta Tentschert, Frank Bierkandt
In vitro inhalation toxicology methods are increasingly being used for research and regulatory purposes. While the opportunity for increased human relevance of in vitro inhalation methods compared to in vivo tests has been established and discussed, how to

Critical considerations for the design of multi-organ microphysiological systems (MPS)

September 9, 2021
Author(s)
Mridu Malik, Yang Yang, Parinaz Fathi, Gretchen Mahler, Mandy Esch
The process of identifying new drugs and getting them approved for use in patients requires extensive preclinical studies and clinical trials. Preclinical studies rely on in vitro experiments and animal models of human diseases. The reliability of data

The YcnI protein from Bacillus subtilis contains a copper-binding domain

September 1, 2021
Author(s)
Madhura Damle, Stephen Peters, Veronika Szalai, Oriana Fisher
Bacteria require a precise balance of copper ions to ensure that essential cuproproteins are fully metalated while also avoiding copper-induced toxicity. The Gram-positive bacterium Bacillus subtilis maintains appropriate copper homeostasis in part through

Analysis of Seafood Reference Materials: RM 8256, RM 8257, RM 8258 and RM 8259

August 30, 2021

NIST Reference Material (RM) 8256 Wild-caught Coho Salmon, RM 8257 Aquacultured Coho Salmon, RM 8258 Wild-caught Shrimp and RM 8259 Aquacultured Shrimp were generated for use in authentication, nutrition and food safety-related determinations of crude fat

Ultraviolet Radiation Technologies and Healthcare Associated Infections: Standards and Metrology Needs

August 20, 2021
Author(s)
Dianne L. Poster, C Cameron Miller, Richard Martinello, Norman Horn, Michael T. Postek, Troy Cowan, Yaw S. Obeng, John J. Kasianowicz
The National Institute of Standards and Technology (NIST) hosted an international workshop on ultraviolet-C (UV-C) disinfection technologies on January 14 – 15, 2020 in Gaithersburg, Maryland in collaboration with the International Ultraviolet Association

Challenges of Accuracy in Germline Clinical Sequencing Data

July 20, 2021
Author(s)
Justin Zook, Ryan Poplin, Mark DePristo
Physicians are increasingly using clinical sequencing tests to establish diagnoses of patients who might have genetic disorders, which means that accuracy of sequencing and interpretation are important elements in ensuring the benefits of genetic testing

MS_Piano: A Software Tool for Annotating Peaks in CID Tandem Mass Spectra of Peptides and N-Glycopeptides

July 15, 2021
Author(s)
Xiaoyu Yang, Pedatsur Neta, Yuri Mirokhin, Dmitrii Tchekhovskoi, Concepcion Remoroza, Meghan Burke, Yuxue Liang, Sanford Markey, Stephen Stein
Annotating product ion peaks in tandem mass spectra is essential for evaluating spectral quality and validating peptide identification. This task is more complex for glycopeptides and is crucial for the confident determination of glycosylation sites in

Universal Spectrum Identifier for mass spectra
