Compositions including a complex of fatty acids (e.g., including one or more C4 to C40 fatty acids, such as a C4 to C20 fatty acid) and one or more amino acids (and particularly one or more amino acids having electrically charged basic side chains, e.g., Arginine, Lysine, etc.) for use as an anti-pathogenic composition. In particular, described herein are compositions of decanoic acid:Arginine in which the decanoic acid and Arginine for a complex having a lamellar supramolecular structure.

Compositions of fatty acids (e.g., including one or more C4 to C40 fatty acids, such as a C4 to C20 fatty acid) and one or more amino acids (and particularly one or more amino acids having electrically charged basic side chains, e.g., Arginine, Lysine, etc.) for use as an anti-pathogenic composition. These compositions may find particular use as anti-bacterial and in some variations anti-viral, anti-fungal and anti-cancer compositions.

A tubular nonwoven structure as an active agent carrier (sleeve) for the atraumatic treatment of hollow organs, in particular applicable via a balloon catheter, as well as a method for the production thereof, wherein the sleeve is folded about a longitudinal sleeve axis in an initial state and is unfoldable in a final state for attachment to an inner wall of a hollow organ, the tubular sleeve is formed of first biodegradable polymer nanofibers and the folding of the sleeve is directed as pleating about a longitudinal sleeve axis, a medicinal active agent is incorporated into the first polymer nanofibers and/or is arranged in interspaces between the polymer nanofibers, and the first polymer fibers are formed such that the polymer fibers degrade over a period of 2 weeks to 3 months so that the active agent can be delivered to a hollow organ wall in this period of time.
