Vital mobilities of medical oxygen: Theorising oxygen justice.

How can societal circulations of medical oxygen be more just? Informed by disparities experienced and lessons learned from the global Covid pandemic, we use vital mobilities to describe and analyse the social lives of medical oxygen and explore opportunities for oxygen justice. Inspired by two distinct yet related theoretical spheres - breath studies and health justice - and contrasting the experiences of high- and low-and middle-income countries, we highlight disparities in medical oxygen availability as a basis to theorise oxygen justice. Engaging with health systems as complex social interactions spanning a range of actors and activities, we use a desk-based 'follow the thing' approach to trace medical oxygen.

Preservation of protective capacity of hyperimmune anti-Stx2 bovine colostrum against enterohemorrhagic Escherichia coli O157:H7 pathogenicity after pasteurization and spray-drying processes.

Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is a major etiologic agent that causes bloody diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS). Shiga toxin (Stx) is the main virulence factor of EHEC responsible for the progression to HUS. Although many laboratories have made efforts to develop an effective treatment for Stx-mediated HUS, a specific therapy has not been found yet.
