The Impact of Community Generated PPE During the SARS-COV-2 Pandemic in Southeast Alabama and Gulfport Mississippi.

The early stages of the SARS-COV-2 pandemic left many hospital systems devoid of personal protective equipment. Community-driven groups manufactured Personal Protective Equipment (PPE) as a form of temporary replacement until supply could increase to frontline healthcare workers. The purpose of this study was to survey hospital systems in Alabama and Mississippi who requested and received PPE to determine recipient opinions concerning community involvement.

A cellular automaton based on plasma membrane turnover accurately recapitulates cell mechanics during epithelial scattering.

Epithelial cells can be triggered to actively detach from epithelial tissues and become solitary, migratory and invasive. This process occurs repeatedly in development, where it is termed epithelial-mesenchymal transition (EMT), and can be recapitulated as epithelial scattering in cell culture models. Detachment of cell-cell junctions involves changes in contractile forces, actin cytoskeletal organization, changes in cell-substrate adhesion properties, surface presentation of cell-cell adhesion molecules, and gene expression.
