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 novel individual metabolic profile characterize the protein kinase B-alpha ( pkb-/- ) in vivo model?
Answer: Specific metabolic characterization should be assessed individually. Therefore, our in silico model enables novel insights inaugurating specific primary preventive strategies targeting individual metabolic profiling precisely.
answer:
yes

question:
Question: Does severe nutritional risk predict decreased long-term survival in geriatric patients undergoing pancreaticoduodenectomy for benign disease?
Answer: Severe nutritional risk can be a useful predictor of long-term survival in geriatric patients undergoing PD, and could improve patient risk stratification preoperatively. Nonoperative management should be strongly considered in geriatric patients with SNR, when malignancy is not suspected.
answer:
yes
