Ex Input:
Question: Does inhibition of late sodium current attenuate ionic arrhythmia mechanism in ventricular myocytes expressing LaminA-N195K mutation?
Answer: Inhibition of late I

Ex Output:
yes

Ex Input:
Question: Is herpes simplex virus type 1 transcription detectable in quiescent human stromal keratitis by in situ hybridization?
Answer: At the level of detection afforded by in situ hybridization, HSV persistent in scarred human corneas after stromal keratitis appears to be transcriptionally dormant. This contrasts with the situation in neurons of latently infected sensory ganglia, in which LATs are present at high levels.

Ex Output:
no

Ex Input:
Question: Are lesion progression and plaque composition altered in older apoE-/- mice lacking tumor necrosis factor-alpha receptor p55?
Answer: Progression and destabilization of advanced atherosclerotic lesions does not seem to be mediated via the TNF-alpha receptor p55.

Ex Output:
no
