SOLUTION: no

PROBLEM: Question: Does peroxiredoxin II negatively regulate lipopolysaccharide-induced osteoclast formation and bone loss via JNK and STAT3?
Answer: We suggest that PrxII could be useful in the development of a novel target for inflammatory bone loss.

SOLUTION: yes

PROBLEM: Question: Does fludrocortisone prevent orthostatic hypotension in astronauts after spaceflight?
Answer: Treatment with a single dose of fludrocortisone results in protection of plasma volume but no protection of orthostatic tolerance. Fludrocortisone is not recommended as a countermeasure for spaceflight-induced orthostatic intolerance.

SOLUTION:
no
