Input: Consider Input: 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.

Output: no


Input: Consider Input: Question: Are cXXC4 mRNA levels associated with clinicopathological parameters and survival of myelodysplastic syndrome patients?

Output: yes


Input: Consider Input: Question: Does porcine liver vascular bed in Biodur E20 corrosion cast?
Answer: Only Biodur E20®Plus appeared to be suitable for high-volume vascular corrosion casting due to its optimal permeability, sufficient processing time and minimum fragility. Biodur E20® Plus is slightly elastic, radio-opaque and alcohol-resistant. These properties make this acrylic resin suitable for not only vascular research but also teaching purposes.


Output: yes
