Understanding the dynamics of physiological changes, protein expression, and PFAS in wildlife

January 15, 2022
Author(s)
Jacqueline Bangma, T.C. Guillette, Paige Bommarito, Carla Ng, Jessica L. Reiner, Andrew Lindstrom, Mark Strynar
Per- and polyfluoroalkyl substances (PFAS) accumulation and elimination in both wildlife and humans is largely attributed to PFAS interactions with proteins, including but not limited to organic anion transporters (OATs), fatty acid binding proteins (FABPs

Eite Tiesinga, Peter J. Mohr, David B. Newell, Barry N. Taylor
We report the 2018 self-consistent values of constants and conversion factors of physics and chemistry recommended by the Committee on Data of the International Science Council (CODATA). The recommended values can also be found at physics.nist.gov

HDX-MS and MD simulations provide evidence for stabilization of the IgG1- FcgRIa (CD64a) immune complex through intermolecular glycoprotein bonds

December 8, 2021

Khan, Kimberly Robyak, Mark Kilbane, Neil Parker, Vincent Chen, Robert Fitzgerald, Sohail Mushtaq, Michael W. Clarke, Norma Breen, Christine Simpson, Stephen A. Wise
The Vitamin D External Quality Assessment Scheme (DEQAS) distributes human serum samples four times per year to over 1000 participants worldwide for the determination of total serum 25-hydroxyvitamin D [25(OH)D)]. These samples are stored at −40 °C prior

Spatially Resolved Potential and Li-Ion Distributions Reveal Performance-Limiting Regions in Solid-State Batteries

Author(s)
Elliot Fuller, Evgheni Strelcov, Jamie Weaver, Michael Swift, Joshua Sugar, Andrei Kolmakov, Nikolai Zhitenev, Jabez J. McClelland, Yue Qi, Joseph Dura, Alec Talin
The performance of solid-state electrochemical systems is intimately tied to the potential and lithium distributions across electrolyte–electrode junctions that give rise to interface impedance. Here, we combine two operando methods, Kelvin probe force
