Adriana Weinberg,Lin-Ye Song,Cynthia L. Wilkening,Anne Sevin,Bruce Blais,Raul Louzao,Dana Stein,Patricia Defechereux,Deborah Durand,Eric Riedel,Nancy Raftery,Renee Jesser,Betty S. Brown,M. Fran Keller,Ruth Dickover,Elizabeth J. McFarland,Terence Fenton +16 more
TL;DR: It was determined that slowly diluting the thawed PBMC significantly improved viable cell recovery, whereas the use of benzonase improved cell recovery only sometimes, and LPA and flow cytometry assay results for cryopreserved and fresh PBMC were highly correlated.
Journal ArticleDOI

TL;DR: A combination of risk-reduction strategies and frequent surveillance testing likely contributed to a prolonged period of low transmission on campus, highlighting the importance of combined testing and contact tracing strategies beyond symptomatic testing, in association with other preventive measures.
Journal ArticleDOI

TL;DR: Common V3-specific Ab responses in maternal plasma predicted a reduced risk of MTCT and mediated autologous virus neutralization, suggesting that boosting these maternal Ab responses may further reduce HIV-1 MTCT.
Journal ArticleDOI

TL;DR: PBMC from 12 HIV-infected and 12 uninfected donors showed that Ln/LN conferred higher viability and recovery than LN/DI or 70/DI 3, 6, 9 or 12, and ELISPOT values significantly decreased with the duration of storage at -70°C both in HIV- Infected and unin infected donors.

TL;DR: Hispanic ethnicity and an infected sibling close contact are associated with increased SARS-CoV-2 infection risk among children, while asthma is associated with decreased risk.
