Remote management of library staff: Challenges and practical solutions.

COVID-19 has forced staff in academic libraries across the world to pivot from face-to-face workdays and services to fully remote (and, in some cases, back again) with very little time or notice. This new reality has presented new challenges in the remote management of staff that may also be working remotely, or in the building. This column explores some of those challenges and presents possible solutions for those at all levels of library management.

Cytoskeletal protein and mRNA accumulation during brush border formation in adult chicken enterocytes.

We have explored the development of the brush border in adult chicken enterocytes by analyzing the cytoskeletal protein and mRNA levels as enterocytes arise from crypt stem cells and differentiate as they move toward the villus. At the base of the crypt, a small population of cells contain a rudimentary terminal web and a few short microvilli with long rootlets. These microvilli appear to arise from bundles of actin filaments which nucleate on the plasma membrane.

Fine structure of shark leucocytes during chemotactic migration.

It has previously been demonstrated that peripheral blood leucocytes of the nurse shark (Ginglymostoma cirrhatum) are capable of in vitro chemotaxis. In the present study we have identified the chemotactic cells as the shark granulocyte and monocyte-macrophage. Chemotaxis assays were set up in blind well chambers.

Immunological cross-reactivity of anionic proteins from caries-free and caries-active salivas which differ in biological properties toward oral streptococci.

We examined whether the anionic antimicrobial proteins in the saliva of certain caries-free (CF) individuals are immunologically cross-reactive with proteins in caries-active (CA) saliva which display identical isoelectric points but which exhibit growth-supportive properties for the oral streptococci. In the immunoblotting experiments reported here, the proteins present in CF and CA whole salivas reacted similarly with an antiserum prepared against the anionic inhibitory proteins. This antiserum also showed identical reactivity with the purified protein fraction containing the anionic proteins of interest from whole saliva of either CF or CA subjects.

Chemotaxis of nurse shark leukocytes.

Studies were conducted to determine the ability of leukocytes from the nurse shark to migrate in an in vitro micropore filter chemotaxis assay and to determine optimal assay conditions and suitable attractants for such an assay. A migratory response was seen with several attractants: activated rat serum, activated shark plasma, and a pool of shark complement components. Only the response to activated rat serum was chemotactic, as determined by the checkerboard assay.
