in order to prepare polyurethane elastomers with acceptable physical properties and good biocompatibility, novel polyurethane networks were synthesized via curing reaction of epoxy-terminated polyurethane prepolymers (eups) with hexamethylene diamine. eups were prepared from reaction of glycidol with nco-terminated polyurethanes (itps). itps were also synthesized from reaction of one equivalent...

objective(s):  titanium oxides are known to be appropriate hemocompatible materials which are suggested as coatings for blood-contacting devices. little is known about the influence of nanometric crystal structure, layer thickness, and semiconducting characteristics of tio2 on blood hemostasis.   materials and methods: having used sol-gel dip coating method in this study, tio2 thin films were d...

Background and Aim: One of the main goals of blood transfusion medicine is to determine the compatibility of the blood products with the patients. Therefore, clinical and laboratory (serologic) evaluations should be done to determine the maximum compatibility (or minimum incompatibility). The most known blood groups is the ABO antigenic system and the most important of them is Rh system. Among ...

We present a new technique for the evaluation of polymer blood compatibility that makes use of a microchannel array flow analyzer and we describe and characterize the flow dynamics of this instrument. The blood compatibility of four polymers is quantitatively and qualitatively assessed and the results discussed. The blood is allowed to flow through the channels of a polymer coated micro-fluidic...

BACKGROUND The growing awareness of transfusion-associated morbidity and mortality necessitates investigations into the underlying mechanisms. Small animals have been the dominant transfusion model but have associated limitations. This study aimed to develop a comprehensive large animal (ovine) model of transfusion encompassing: blood collection, processing and storage, compatibility testing ri...

Patients with autoimmune haemolytic anaemia (AIHA) frequently have anaemia of sufficient severity as to require a blood transfusion. However, it is impossible to find compatible blood when, as is frequently the case, the autoantibody in the patient's serum reacts with all normal red blood cells. Further, the autoantibody may mask the presence of a red cell alloantibody capable of causing a haem...
