Abstract: An assembly is provided for rotational equipment. This assembly includes a seal device, a ring structure and a fastener. The seal device includes a plurality of seal shoes, a seal base, a plurality of spring elements and a fastener aperture extending axially through the seal device. The seal shoes are arranged around a centerline in an annular array. The seal shoes include a first seal shoe. The seal base circumscribes the annular array. The spring elements include a first spring element. The first spring element connects and extends between the first seal shoe and the seal base. The ring structure is axially adjacent the seal device. The fastener is mated with the fastener aperture and abutted axially against the ring structure.

Abstract: The present disclosure provides a cargo delivery fusion polypeptide comprising an endosomolytic polypeptide and a cell penetrating polypeptide; and compositions comprising the cargo delivery fusion polypeptide. The present disclosure also provides methods of delivering a cargo into a target eukaryotic cell, using a composition comprising an amphiphilic polypeptide.
