This disclosure relates to a wound care device which contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device contains a perforated adhesive layer.

The invention provides method of guiding unidirectional movement of a cell comprising exposing the cell to a surface comprising an asymmetric, three-dimensional pattern of one or a plurality of topographical elements for a time period sufficient to bias actin polymerization within the cell. The invention also provides methods of inducing directional movement of a cell, and methods of harnessing an actin wave within a cell. In addition, the invention provides compositions comprising a contact side, wherein at least a portion of the contact side comprises a cell contact portion comprising an asymmetric, three-dimensional pattern of one or a plurality of topographical elements, and methods of inducing healing of a wound of a subject comprising contacting the wound with the composition.

Absorbent articles, such as diapers or sanitary napkins, comprising a hydrophilic hot melt adhesive with water wetting properties. The hydrophilic hot melt adhesive comprises an ethylene copolymer selected from the group consisting of ethylene vinyl acetate, ethylene n-butyl acrylate, ethylene octene, ethylene propylene, ethylene butene propylene, and mixtures thereof and a nonionic, fatty alcohol ethoxylate surfactant. The hot melt adhesive is particularly suitable for bonding a nonwoven to another component of the article.
