Abstract: A thermoplastic fiber demonstrates moisture wicking properties. The fiber has one or more internal lenghtwise open channels each having an opening and at least one groove having a deepest point, a longest dimension and a mouth. The mouth is defined by moving a line from the deepest point along the longest dimension until the largest convex set is identified. The mouth is at the line segment closing the largest convex set. The mouth has width x wherein the average transverse cross-sectional area of the groove is greater than or equal to (.pi.x.sup.2)/8. A durable hydrophilic surface modification is assosiated with said channel.

Abstract: Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor .alpha. (hTNF.alpha.) are disclosed. These antibodies have high affinity for hTNF.alpha. (e.g., K.sub.d =10.sup.-8 M or less), a slow off rate for hTNF.alpha. dissociation (e.g., K.sub.off =10.sup.-3 sec.sup.-1 or less) and neutralize hTNF.alpha. activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNF.alpha. and for inhibiting hTNF.alpha. activity, e.g., in a human subject suffering from a disorder in which hTNF.alpha. activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.
