Question: Question: Does the Drosophila Chmp1 protein determine wing cell fate through regulation of epidermal growth factor receptor signaling?
Answer: Drosophila Chmp1 negatively regulates DER signaling, likely through its role in MVB formation. Loss of Chmp1 activity in the Drosophila wing induces a cell fate change from intervein to vein that should provide a useful tool for future studies of ESCRT protein activity.

Answer: yes


Question: Question: Does endothelial cell chimerism influence allograft tolerance in liver transplant patients after withdrawal of immunosuppression?
Answer: Endothelial cell chimerism has nothing to do with the induction of clinical tolerance in liver transplant patients after withdrawal of immunosuppression.

Answer: no


Question: Question: Does centrifugation after irradiation of red blood cells accelerate haemolysis?
Answer: There is no difference in the haemolysis caused by centrifugation between irradiated and non-irradiated RBCs. However, it is well known that washing RBCs after irradiation significantly lowers the potassium content. Summarising these two findings leads to the conclusion that it is optimal first to irradiate and then to wash RBCs.

Answer:
no
