Control of interfacial structures and anti-platelet adhesion property of blood-compatible random copolymers.

Fibrinogen adsorption behavior on the blood-compatible polymer, poly(2-methoxyethyl acrylate) (PMEA), non-blood-compatible polymer, poly(-butyl acrylate) (PBA), and random copolymers of both were examined. Adsorption and denaturation of fibrinogen on the polymers increased as the ratio of PBA increased. The incremental change corresponded to the amount of intermediate water included in the hydrated polymers.

Perioral movements and sucking pattern during bottle feeding with a novel, experimental teat are similar to breastfeeding.

Objective: To measure intraoral pressure and perioral movement in infants during breastfeeding (BF) and feeding with experimental teat (ET). The teat has a wide base, firm shaft and a valve at the base, such that milk flows only when the baby provides a hold pressure.

Study Design: Twenty healthy term infants, between 1 and 8 months old, were enrolled in the study.
