    摘要： The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreated article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional —OH end groups and reacting the —OH ends with a conventional monomer or prepolymer of a film-forming polymer capable of reacting with —OH groups. Such reactions are exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The —OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure. The film can be applied to the surface of an article by any convenient means of coating the article with the reaction mixture in solvent, and allowing the solvent to evaporate.

    摘要： The present invention relates to high cut-off hemodialysis membranes for the treatment of chronic hemodialysis (CHD) patients, with the potential to improve long-term survival of these patients by reducing the risk of cardiovascular disease, through down-regulation of monocyte activation in the blood. Monocytes are the major circulating blood cells involved in the progression of cardiovascular disease. High cut-off hemodialysis in chronic dialysis patients results in a sustained decrease in expression of monocyte cell-surface proteins that direct the movement of these cells from the blood to the walls of blood vessels, where they promote the progression of arterial disease (atherosclerosis) that leads to cardiovascular disease (CVD); heart disease, strokes and peripheral vascular disease.

    摘要： The membrane producible by shaping a polymer blend or a block copolymer comprising blocks of monomer units, loading the polymer blend or block copolymer with a blowing gas concentration within the polymer blend or block polymer above a critical concentration at a temperature below a critical temperature, but above the glass transition temperature of the polymer blend/gas or block copolymer/gas mixture and finally stabilizing the foam structure is characterized in that as polymer blend a homogeneous polymer blend comprising at least one hydrophilic and at least one hydrophobic polymer and/or a block copolymer of alternating blocks of hydrophilic and hydrophobic monomer units is used, both the polymer blend and the block copolymer having a solubility relating to the used foaming gas above the critical concentration. The said membrane is used for medical purposes, especially for the haemodialysis, haemofiltration, haemodiafiltration, plasmapherese, immunotherapy, micro- or ultrafiltration or gas separation.
