Polyethylene encased porous poly(chloromethylstyrene-co-divinylbenzene) disks have been prepared by polymerization in a cylindrical glass mold and cut to a disk format. Following attachment of a free radical azo initiator 4,4'-azobis(4-cyanovaleric acid) to available functionalities at the surface of the pores...

We have investigated the influence of the free radical initiator characteristics on red blood cell lipid peroxidation, membrane protein modification, and haemoglobin oxidation. 2,2'-Azobis(2-amidinopropane) (AAPH) and 4,4'-azobis(4-cyanovaleric acid) (ACV) were employed as free radical sources. Both azo-compounds are water-soluble, although...

AIBN and ACVA oxidative forced degradation models are examined for two drug molecules whose predominant oxidation chemistries arise from different reaction mechanisms (i.e., free radical vs. nucleophilic). Stress was conducted under a variety of initiator concentrations, and under ambient and...

Haemolysis induced by a free radical initiator (4,4'azobis-(4-cyanovaleric acid) has been studied with transfusion blood. Azobis cyanovaleric acid caused an increase in haemolysis. The effect of alpha- and gamma-tocopherol, 2,2,5,7,8 pentamethyl-6-chromanol and 2,2,7,8 tetramethyl-6-chromanol on the red blood cell haemolysis...
