Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

Advanced Materials Technologies, EarlyView.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

Bias and negative values of COVID-19 vaccine effectiveness estimates from a test-negative design without controlling for prior SARS-CoV-2 infection

Nature Communications
Test-negative designs (TNDs) are used to assess vaccine effectiveness (VE). Protection from infection-induced immunity may confound the association between case and vaccination status, but collecting reliable infection history can be challenging.

NSP7 Molecular Degrader Attenuates Coronaviral Infection Through the β‐TrCP1/FBXO5 Axis

Advanced Science, EarlyView.
Host E3 ligase FBXO5 as a key regulator that promotes K48‐linked ubiquitination and proteasomal degradation of SARS‐CoV‐2 NSP7, thereby suppressing viral replication. NSP7 ubiquitination is co‐regulated by β‐TrCP1 and TAF1. Small molecule BC24877 disrupts β‐TrCP1‐mediated degradation of FBXO5, stabilizing FBXO5 and enhancing NSP7 clearance ...
