31 Supportive care after antibody infusion and transplantation was given as previously described.32 Dogs that experienced elevations of hepatic enzymes were treated with ursodiol (7.5 mg/kg given orally twice a day) for the remainder of the study period. Engraftment was assessed by the recovery of...
One method is to introduce a bulky hydrophobic substituent at the 4-position of the aromatic ring in the side chain and the other is to add a methyl group to the α-carbon. In the former case, although it is possible to obtain high affinity, the transport activity decreases, and its ...
Alpha-particle radiotherapy has gained considerable attention owing to its potent anti-cancer effect. 211At, with a relatively short half-life of 7.2 h, emits an alpha particle within a few cell diameters with high kinetic energy, which damages cancer ce
