[EX Q]: 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 A]: no

[EX Q]: Question: Is serum free 1,25-dihydroxy-vitamin D more closely associated with fibroblast growth factor 23 than other vitamin D forms in chronic dialysis patients?
Answer: The relationship between FGF-23 and vitamin D is stronger using free forms of 25-OH-D and 1,25-(OH)2-D. Subsequent studies aiming at MBD should consider including free 25-OH-D and 1,25-(OH)2-D in the analysis.
[EX A]:
yes
