The idiotype network hypothesis proposed by Jerne (1) has led to considerable interest in whether physiologic immunoregulation is accomplished by the interaction of receptor molecules and anti-receptors directed at unique idiotypic determinants. Another issue of importance, related to mechanistic questions, is whether exogenously administered anti-receptor antibodies might be used to manipulate...

During RoboCup'99 in Stockholm, we arranged the rst RoboCup Jr. Here, the aim was to allow children to get hands-on experience with robotics, and for this purpose we set up a LEGO Mindstorms robot soccer game for children. We developed the user-guided behavior-based approach in order to allow non-expert users to develop their own robots in an easy and fast manner. Indeed, using this approach, c...

Jr(a) is a high-prevalence antigen. The rare Jr(a-) individuals can form anti-Jr(a) after exposure to the Jr(a) antigen through transfusion or pregnancy. The clinical significance of anti-Jr(a) is not well established. This study reports a case of a 31-year-old woman with a previously identified anti-Jr(a) who required massive transfusion of RBCs after developing life-threatening postpartum dis...
