Question: Question: Is muscle dysfunction during exercise of a single skeletal muscle in rats with congestive heart failure associated with reduced muscle blood supply?
Answer: The cause of contractile dysfunction in a single exercising skeletal muscle in rats with CHF cannot be explained simply by reduced blood supply. In addition, absence of changes in high-energy phosphates and metabolites indicate that the oxidative metabolism of SOL is intact in rats with CHF.

Answer: no


Question: Question: Does three-dimensional assessment of ultrasound features in women with clomiphene citrate-resistant polycystic ovarian syndrome ( PCOS ) : ovarian stromal volume correlate with biochemical indices?
Answer: These findings demonstrate an association of the total ovarian volume, pre-antral follicle number and total follicular volume with some of the biochemical indices of PCOS, but no association was observed between ovarian stromal volume and these indices.

Answer: no


Question: Question: Does next-generation sequencing survey of biliary tract cancer reveal the association between tumor somatic variants and chemotherapy resistance?
Answer: In the largest exploratory analysis of this kind for BTC, 3 prevalent, mutually exclusive mutations represent distinct patient cohorts. These mutations are prognostic and may represent a predictive biomarker for a GP response. Prospective studies to validate these findings are needed, and they should include the incorporation of therapies that exploit the genomic instability observed with these mutations in BTC.
