Abstract: Methods of producing macromolecular compositions and using same are provided. The method includes preparing a resin material; forming an acetyl group on the resin material; and oxidizing the acetyl group via a one-step reaction including reacting a sulfoxide and an acid with the acetyl group to form a ketoaldehyde group. The macromolecular compositions are capable of removing an effective amount of one or more constituents from a physiological solution, such as urea during dialysis therapy.

Abstract: A method for priming a hemodialyzer is disclosed. Hemodialyzer comprises a dialysate compartment, a blood compartment, and a dialysis membrane separating the dialysate and blood compartments. The method comprises the steps of delivering a liquid to a dialysate inlet of the dialysate compartment at a first volumetric delivery rate, passing the liquid through the dialysate compartment from the dialysate inlet to a dialysate outlet of the hemodialyzer and delivering the liquid from the dialysate outlet at a second volumetric delivery rate that is less than the first volumetric delivery rate so as to cause a net flow of the liquid from the dialysate compartment to the blood compartment through the dialysis membrane.

Abstract: A steam sterilizable monolayer medical tubing comprising a blend of a melt strength enhancing agent of a homopolymer or copolymer of polypropylene having free-end long chain branches of propylene units, a melt flow index of greater than 10 and in an amount of 1-10% by weight and a second component selected from the group of (i) a selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene and (ii) a selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene to which has been grafted, an alpha, beta-olenfically unsaturated monocarboxylic or dicarboxylic acid reagent.
Abstract: Dialysis machine for alternatively hospital care and self-care having a touch screen (16) which can be adjusted universally and to a desired vertical position on the dialysis machine and can be locked in the desired adjusted position. As a consequence thereof, the touch screen can be arrested in a position in relation to the position of the person controlling the dialysis machine which allows the touch screen to be comfortably reached irrespective of the position of said person.
Abstract: A flush-storage solution for flushing blood out of a donor organ and cold-storing the donor organ prior to transplantation is provided. The solution of the present invention includes mannitol as an impermeable solute. The present invention also provides an improved method of flushing and cold-storing donor organs as well as an improved method of transplanting donor organs into a recipient.
