thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

The effect of plasma on degradation of human growth hormonereleasing hormone (GRH) was examined in vitro and in vivo using high performance liquid chromatography (HPLC), radioimmunoassay (RIA), and bioassay. When GRH(1-44)-NH2 was incubated with human plasma, the t1/2 of total GRH immunoreactivity was 63 min (RIA). However, HPLC revealed a more rapid disappearance (t1/2, 17 min) ofGRH(144)-NH2 ...
