question:
Question: Does patellar taping change the amplitude of electromyographic activity of the vasti in a stair stepping task?
Answer: The results of this study indicate that the positive clinical effects of medially directed therapeutic tape are not due to changes in EMG amplitude of the vasti muscle. Thus other effects such as changes in timing of contraction of the vasti are more likely candidates for the mechanism of efficacy.
answer:
no


question:
Question: Do lactotripeptides lower ambulatory blood pressure in untreated whites : results from 2 controlled multicenter crossover studies?
Answer: The data do not support a BP-lowering effect of LTPs in whites.
answer:
no


question:
Question: Does epigenome-wide DNA methylation assay reveal placental epigenetic markers for noninvasive fetal single-nucleotide polymorphism genotyping in maternal plasma?
Answer: The present studies systematically identified hypermethylated sites in fetal tissues and preliminarily demonstrated that some of the fetal epigenetic markers that contain informative SNPs have great potential for noninvasive fetal genetic diagnosis.
answer:

yes
