Capturing COVID-19-Like Symptoms at Scale Using Banner Ads on an Online News Platform: Pilot Survey Study.

Background: Identifying new COVID-19 cases is challenging. Not every suspected case undergoes testing, because testing kits and other equipment are limited in many parts of the world. Yet populations increasingly use the internet to manage both home and work life during the pandemic, giving researchers mediated connections to millions of people sheltering in place.

Coping and survival skills: the role school personnel play regarding support for bullied sexual minority-oriented youth.

Background: Research has shown that bullying has serious health consequences, and sexual minority-oriented youth are disproportionately affected. Sexual minority-oriented youth include lesbian, gay, bisexual, transgender, queer, or questioning (LGBTQ) individuals. This study examined the bullying experiences of sexual minority-oriented youth in a predominantly rural area of a Midwestern state.

Contextualizing gay-straight alliances: student, advisor, and structural factors related to positive youth development among members.

Gay-straight alliances (GSAs) may promote resilience. Yet, what GSA components predict well-being? Among 146 youth and advisors in 13 GSAs (58% lesbian, gay, bisexual, or questioning; 64% White; 38% received free/reduced-cost lunch), student (demographics, victimization, attendance frequency, leadership, support, control), advisor (years served, training, control), and contextual factors (overall support or advocacy, outside support for the GSA) that predicted purpose, mastery, and self-esteem were tested. In multilevel models, GSA support predicted all outcomes.

Measurement of serum haptoglobin in neonatal farm-raised and bob veal calves using two immunoassay methods.

Two immunoassays using an anti-bovine haptoglobin monoclonal antibody, Hap 1, were used to measure serum haptoglobin levels in neonatal farm-raised and bob veal calves. Bob veal calves were grouped into condemned, normal, and icteric groups based on the appearance of the carcass and viscera at postmortem examination. The competitive inhibition assay was more sensitive than the direct hemoglobin binding assay in detecting low levels of haptoglobin in all groups of calves.
