Input: Consider Input: Question: Is ischemic preconditioning cardioprotective in senescent human myocardium?
Answer: Our data indicate that ischemic preconditioning has no beneficial effect on the postischemic functional recovery of senescent human myocardium.

Output: no

Input: Consider Input: Question: Does effective inhibition of nitric oxide production by aminoguanidine reverse hypotension in endotoxaemic rats?
Answer: AG inhibited NO formation in a dose-dependent way. Yet, AG had no haemodynamic effects, suggesting a minor cardiovascular influence of iNOS in this endotoxin model, in parallel to what has been found in microbial sepsis.

Output: no

Input: Consider Input: Question: Is hypercholesterolaemia associated with early atherosclerotic lesions in primary biliary cirrhosis?
Answer: Hypercholesterolaemia is not consistently associated with subclinical atherosclerosis in PBC, but should be treated if other risk factors for cardiovascular disease are also present. The search for factors that may protect patients with hypercholesterolaemic PBC against atherosclerosis should be encouraged.
Output: no
