Overcoming the ABO incompatibility barrier

Overcoming the ABO incompatibility barrier in pediatric renal transplantation.

BACKGROUND ABO blood type incompatibility between a donor and recipient is generally considered a contraindication to kidney transplantation. CASE CHARACTERISTICS A 12-year-old boy presented with end stage renal disease (blood group B), with the only healthy available donor being mother (blood group AB). The child received renal transplant with mother as the donor, with a designed desensitiza...

ABO incompatibility: which one matters?

Hydrops fetalis due to ABO incompatibility.

Hemolytic disease of the newborn due to ABO incompatibility was first observed by Halbrecht in 1944. This entity has a spectrum ranging from minimal hemolysis requiring no therapy, as is the case in most instances, to severe hemolytic disease requiring aggressive management including exchange transfusion in a small percentage of cases. An extreme degree of hemolytic disease of the newborn due t...

Overcoming the Bradyon–Tachyon Barrier

In this study, the problem of overcoming the infinite energy barrier separating the bradyonic and tachyonic realms is investigated. Making use of the Majorana equation for particles with arbitrary spin and the Heisenberg uncertainty principle, it is proved that, under certain conditions of spatial confinement, quantum fluctuations allow particles with very small mass and velocity close to the s...
