Comments P.3 left column 2nd paragraph: "For collagen, with l≈300nm and d≈1.08nm [BNID 112905], [investigators] have p[ratio of length to diameter]≈278. Assuming a dilute suspension of collagen in water at body temperature, with Ƞwater≈0.67cP [BNID 108528], kBT≈4.3pN×nm [BNID 101858], and A̝[tortuosity factor]=0.54, [they] combine equations (5) and (6) to obtain Dcol=D0×A̝≈7.3µm^2/sec^2 (7)."
