Crisis Librarianship: An Examination of Online Librarianship Roles in the Wake of the COVID-19 Pandemic.

This study surveyed the members of a professional library organization for their perceptions of their online librarianship role. In particular, the survey sought to examine any change in online librarianship roles after March 2020 as a result of the COVID-19 pandemic lockdowns. Participants were administered a survey comprised of both quantitative and qualitative response options.

Perceived social support and self-care in patients hospitalized with heart failure.

Background: Rehospitalization of heart failure patients is often considered the result of inadequate self-care yet only one study documents superior outcomes with better self-care.

Aims: If inadequate self-care is related to hospitalizations, then hospitalized heart failure patients should have lower self-care skills than non-hospitalized patients. The purpose of this study was to evaluate perceived social support and self-care characteristics of patients hospitalized with an exacerbation of heart failure.

Measurement of electrical conduction properties of intact embryonic murine hearts by extracellular microelectrode arrays.

The study of the embryonic development of the cardiac conduction system and its congenital and toxicological defects requires protocols to measure electrical conduction through the myocardium. However, available methods either lack spatial information, necessitate the hearts to be sliced and mounted, or require specialized equipment. Microelectrode arrays (MEAs) are plates with embedded surface electrodes to measure localized extracellular ionic currents (field potentials) created by the depolarization and repolarization of cultured cells and tissue slices.
