[EX Q]: Question: Does fructose Coingestion Accelerate Postexercise Muscle Glycogen Repletion?
Answer: Combined ingestion of glucose plus fructose does not further accelerate postexercise muscle glycogen repletion in trained cyclists when ample carbohydrate is ingested. Combined ingestion of glucose (polymers) plus fructose or sucrose reduces gastrointestinal complaints when ingesting large amounts of carbohydrate.
[EX A]: no

[EX Q]: Question: Does exacerbation of headache during dihydroergotamine for chronic migraine alter outcome?
Answer: After controlling for nausea and other factors, headache exacerbation with DHE infusions is not an independent predictor of poor headache outcome and clinicians should not interpret its presence as a reason to stop treatment. The focus of management should be on controlling nausea as it is the most important modifiable factor in achieving a good headache outcome with an inpatient course of IV DHE for chronic migraine.
[EX A]: no

[EX Q]: Question: Is esophageal carcinoma cell line with high EGFR polysomy responsive to gefitinib?
Answer: We show for the first time a significant treatment response to the EGFR tyrosine kinase inhibitor gefitinib in esophageal tumor cells with a high polysomy for EGFR, suggesting a future role of anti-EGFR therapy for esophageal adenocarcinoma patients with a high EGFR polysomy.
[EX A]:
yes
