Ex Input:
Question: Does oligofructose affect the development of type 1 diabetes mellitus induced by dietary proteins in the diabetes-prone BB rat model?
Answer: In the BB rat model, 5% OF in the diet did not have any protective effects against diet-induced T1DM. The present data do not suggest dietary OF as a promising approach for the dietary prevention of T1DM.

Ex Output:
no


Ex Input:
Question: Is fractional urinary excretion of IgG the most powerful predictor of renoprotection by ACE inhibitors in IgA nephropathy?
Answer: Renoprotection by ACEi is a multifactorial phenomenon: the best predictor of renoprotection is FEIgG, a marker of disruption of glomerular barrier to proteins; renoprotection depends not only on ability to reduce proteinuria, but probably also on antiinflammatory and antifibrotic activity.

Ex Output:
yes
