PROBLEM: Question: Is kREX2 essential for either procyclic or bloodstream form Trypanosoma brucei?
Answer: KREX2 is a U-specific exonuclease that is dispensable for RNA editing in vivo in T. brucei BFs and PFs. This result suggests that the U deletion activity, which is required for RNA editing, is primarily mediated in vivo by KREX1 which is normally found associated with only one type of editosome. The retention of the KREX2 gene implies a non-essential role or a role that is essential in other life cycle stages or conditions.

SOLUTION: no

PROBLEM: Question: Is time point important for effects of syngeneic bone marrow transplantation for type 1 diabetes in mice?
Answer: These results indicated that syn-BMT should be performed, when diabetes is neither too new-onset nor too late-stage. Tregs represent one mechanism for syn-BMT-induced restoration of immune tolerance in STZ-diabetic mice.

SOLUTION: yes

PROBLEM: Question: Does high-dose vitamin E supplementation diminish ribavirin-associated haemolysis in hepatitis C treatment with combination standard alpha-interferon and ribavirin?
Answer: Vitamin E supplementation alone during standard alpha-interferon and ribavirin therapy does not appear to diminish ribavirin-associated haemolysis.

SOLUTION:
no
