Seroprevalence of anti-SARS-CoV-2 antibodies in a cohort of New York City metro blood donors using multiple SARS-CoV-2 serological assays: Implications for controlling the epidemic and "Reopening".

PLoS One 2021 28;16(4):e0250319. Epub 2021 Apr 28.

Laboratory of Stem Cell Regenerative Research, Lindsley F. Kimball Research Institute, New York Blood Center, New York, NY, United States of America.

Projections of the stage of the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) pandemic and local, regional and national public health policies to limit coronavirus spread as well as "reopen" cities and states, are best informed by serum neutralizing antibody titers measured by reproducible, high throughput, and statically credible antibody (Ab) assays. To date, a myriad of Ab tests, both available and FDA authorized for emergency, has led to confusion rather than insight per se. The present study reports the results of a rapid, point-in-time 1,000-person cohort study using serial blood donors in the New York City metropolitan area (NYC) using multiple serological tests, including enzyme-linked immunosorbent assays (ELISAs) and high throughput serological assays (HTSAs).

Successful salvage of the left pulmonary artery in a neonate with isolated unilateral absence of the pulmonary artery.

J Cardiol Cases 2020 May 10;21(5):169-171. Epub 2020 Jan 10.

Department of Pediatrics and Pediatric Cardiology, Kitasato University, Sagamihara, Japan.

Isolated unilateral absence of the pulmonary artery (UAPA) is a congenital anomaly where involution of the extrapulmonary PA is insufficient and the intrapulmonary PA is only fed by the ductus arteriosus. Affected lung disorder causes complications years after ductus closure; thus, early diagnosis is of importance to avoid these complications. Here, we present the case of a male infant who was admitted to the neonatal intensive care unit because of transient tachypnea of the newborn and absence of the left PA (LPA) was indicated.

Seasonal changes of perineuronal nets and song learning in adult canaries (Serinus canaria).

Behav Brain Res 2020 02 16;380:112437. Epub 2019 Dec 16.

Laboratory of Behavioral Neuroendocrinology, GIGA Neurosciences, University of Liege, Belgium. Electronic address:

Songbirds learn their song during a sensitive period of development associated with enhanced neural plasticity. In addition, in open-ended learners such as canaries, a sensitive period for sensorimotor vocal learning reopens each year in the fall and leads to song modifications between successive breeding seasons. The variability observed in song production across seasons in adult canaries correlates with seasonal fluctuations of testosterone concentrations and with morphological changes in nuclei of the song control system (SCS).
