PROBLEM: Question: Does helicobacter pylori infection in Mongolian gerbils initiate hematological diseases?
Answer: A single H. pylori infection is insufficient to cause onset of ITP or IDA and other factors may be required for disease onset.

SOLUTION: no

PROBLEM: Question: Does pimecrolimus affect Langerhans cells in murine epidermis?
Answer: It is therefore unlikely that topically applied pimecrolimus affects epidermal LCs, in contrast to corticosteroids.

SOLUTION: no

PROBLEM: Question: Is p-gp activity a critical resistance factor against AVE9633 and DM4 cytotoxicity in leukaemia cell lines , but not a major mechanism of chemoresistance in cells from acute myeloid leukaemia patients?
Answer: P-gp activity is not a crucial mechanism of chemoresistance to AVE9633. For patients whose resistance to conventional anthracycline AML regimens is related to ABC protein expression, a combination with AVE9633 could be beneficial. Other mechanisms such as microtubule alteration could play an important role in chemoresistance to AVE9633.

SOLUTION:
yes
