[EX Q]: 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.
[EX A]: no

[EX Q]: Question: Is microvasculopathy observed in early or late endomyocardial biopsies related to angiographically confirmed transplanted heart coronary vasculopathy?
Answer: Microvasculopathy observed early or late after OHT was not related to angiographically confirmed CAV.
[EX A]: no

[EX Q]: Question: Is serum level of cartilage oligomeric matrix protein lower in children with idiopathic scoliosis than in non-scoliotic controls?
Answer: COMP was lower in children with idiopathic scoliosis than in a control cohort. In children with scoliosis, high COMP was modestly correlated with high growth velocity, but not with curve severity.
[EX A]:
yes
