Ping Ren

TL;DR: In this paper, a mutant SARS-CoV-2 that lacks the furin cleavage site (ΔPRRA) was generated, which had faster kinetics, improved fitness in Vero E6 cells and reduced spike protein processing.

TL;DR: It is shown that the VGIIc group is clonal and hypothesize it arose recently, and two hallmarks of emerging outbreaks: high clonality and the emergence of novel genotypes via recombination are illustrated.

TL;DR: A fluorescence-based SARS-CoV-2 neutralization assay is reported on that detects Sars- CoV- 2 neutralizing antibodies in COVID-19 patient specimens and yields comparable results to plaque reduction neutralizing assay, the gold standard of serological testing.

TL;DR: This appears to have been the first study to measure all of these home exposures (indoor allergens, nitrogen dioxide, fungi, fungi) and to prospectively measure the frequency of infant wheeze and persistent cough.

TL;DR: A high-throughput procedure that combines automated RNA extraction, amplification, and detection of WNV RNA is described that demonstrated for the first time that the use of an automated system for the purpose of large-scale viral RNA surveillance dramatically increased the speed and efficiency of sample throughput for diagnosis.
