[EX Q]: Question: Does peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?

[EX A]: yes

[EX Q]: Question: Is repeated sputum microscopy essential for monitoring tuberculosis treatment response?
Answer: The yield of a second on-the-spot sputum specimen is negligible, provided that the first smear is from an overnight specimen. From the data available, it is evident that repeated follow-up smears are not essential for documenting treatment outcome.
[EX A]: no

[EX Q]: Question: Does tacrine alter the potency of succinylcholine in the rat?
Answer: Chronic oral tacrine does not alter muscle response to succinylcholine in the rat. This may not apply to Alzheimer patients receiving chronic tacrine since the interaction between acute tacrine and succinylcholine in the rat differs from that in humans.
[EX A]:
no
