Question: Question: Is human endogenous retrovirus ( HERV ) expression induced by treatment with the histone deacetylase ( HDAC ) inhibitors in cellular models of HIV-1 latency?
Answer: We show that HDAC inhibitors did not substantially increase the transcription of the analysed HERV env or pol genes, suggesting that histone acetylation is not crucial for controlling HERV expression in these experimental models and in ex vivo primary human T cells. Importantly, this indicates that unwanted HERV expression does not appear to be a barrier to the use of HDAC inhibitors in HIV-1 cure strategies.

Answer: no


Question: Question: Is [ The increase in the speed of the pulse wave associated with elevated central blood pressure in hypertensive patients with kidney disease ]?
Answer: In hypertensive patients with renal disease PWV is increased, but not the AIx. We believe that the AIx is not a reliable measure of arterial stiffness in hypertensive patients with kidney disease.

Answer: no


Question: Question: Is low percentage of free prostate-specific antigen ( PSA ) a strong predictor of later detection of prostate cancer among Japanese men with serum levels of total PSA of 4.0 ng/mL or less?
Answer: A low %fPSA is a strong predictor of a subsequent diagnosis of prostate cancer among men with tPSA levels ≤4.0 ng/mL. Measurement of %fPSA might enhance the detection of high-grade cancer that warrants aggressive treatment.

Answer:
yes
