AbstractEarly antibody therapy can prevent severe SARS-CoV-2 infection (COVID-19). However, the effectiveness of COVID-19 convalescent plasma (CCP) therapy in treating severe COVID-19 remains inconclusive. To test a hypothesis that some CCP units are associated with a coagulopathy hazard in severe disease that offsets its benefits, we tracked 304 CCP units administered to 414 hospitalized COVID-19 patients to assess their association with the onset of unfavorable post-transfusion D-dimer trends.

It is life-threatening and has a first peak of incidence in childhood, during primary infection.

In Fig. 1B of the Report “Phosphorylation-dependent ubiquitination of cyclin E by the SCFFbw7 ubiquitin ligase” (5 October 2001, p. 173), an image of the positive controls showing ubiquitination of cyclin E/Cdk2 in lanes 10, 11, and 12 was mistakenly used in the positive control lanes 4, 5, and 6 during figure assembly. Both experiments were performed under identical conditions.
