Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Context: Several lines of evidence suggest that the dietary isoflavone genistein (Gen) has beneficial effects with regard to cardiovascular disease and in particular on aspects related to blood pressure and angiogenesis. The biological action of Gen may be, at least in part, attributed to its ability to affect cell signalling and response. However, so far, most of the molecular mechanisms underlying the activity of Gen in the endothelium are unknown.', 'To examine the transcriptional response to 2.5 microM Gen on primary human endothelial cells (HUVEC), we applied cDNA array technology both under baseline condition and after treatment with the pro-atherogenic stimulus, copper-oxidized LDL. The alteration of the expression patterns of individual transcripts was substantiated using either RT-PCR or Northern blotting. Gen significantly affected the expression of genes encoding for proteins centrally involved in the vascular tone such as endothelin-converting enzyme-1, endothelin-2, estrogen related receptor alpha and atrial natriuretic peptide receptor A precursor. Furthermore, Gen countered the effect of oxLDL on mRNA levels encoding for vascular endothelial growth factor receptor 165, types 1 and 2.
Answer: Our data indicate that physiologically achievable levels of Gen change the expression of mRNA encoding for proteins involved in the control of blood pressure under baseline conditions and reduce the angiogenic response to oxLDL in the endothelium.

Output: Does genistein affect the expression of genes involved in blood pressure regulation and angiogenesis in primary human endothelial cells?

Input: Consider Input: Context: Anti-Mullerian hormone (AMH) may have a role in disordered folliculogenesis in polycystic ovary syndrome (PCOS). Though there have been several investigations into circulating AMH levels in patients with PCOS, no previous studies have compared AMH concentrations in the follicular fluid of unstimulated ovaries in women with PCOS with that of normally ovulating women.', 'Follicular fluid was aspirated from 4-8-mm follicles of unstimulated ovaries during routine laparoscopy or laparotomy from women with anovulatory PCOS (n = 11) and those with regular ovulatory cycles (n = 8). Follicular AMH was compared in the two groups. Serum samples were analysed for AMH and endocrine profile.', 'Follicular fluid AMH levels were significantly higher (P < 0.0001) in women with anovulatory PCOS (median: 466.2 ng/ml) compared with normal-ovulatory controls (median: 78.0 ng/ml). Mean follicular fluid AMH levels in PCOS patients were 60 times higher than in the serum. Moreover, there was a significant correlation between the follicular fluid and serum concentrations of AMH in the PCOS group (r = 0.86; P = 0.007) but not in controls.
Answer: Highly elevated AMH in follicular fluid from PCOS patients in contrast to age-matched normal controls suggests that increased circulating concentrations of AMH are partly due to the increased production of AMH by individual follicles and not simply attributable to the increased number of small antral follicles. This suggests an intrinsic abnormality in the ovarian follicles themselves in PCOS, which could contribute to disordered folliculogenesis.

Output: Is anti-Mullerian hormone increased in follicular fluid from unstimulated ovaries in women with polycystic ovary syndrome?

Input: Consider Input: Context: The study compared two channel-reduction approaches in order to investigate the effects of systematic motor imagery (MI) neurofeedback practice in an everyday environment using a very user-friendly EEG system consisting of individualized caps and highly portable hardware.', 'Sixteen BCI novices were trained over four consecutive days to imagine left and right hand movements while receiving feedback. The most informative bipolar channels for use on the subsequent days were identified on the first day for each individual based on a high-density online MI recording.', 'Online classification accuracy on the first day was 85.1% on average (range: 64.7-97.7%). Offline an individually-selected bipolar channel pair based on common spatial patterns significantly outperformed a pair informed by independent component analysis and a standard 10-20 pair. From day 2 to day 4 online MI accuracy increased significantly (day 2: 69.1%; day 4: 73.3%), which was mostly caused by a reduction in ipsilateral event-related desynchronization of sensorimotor rhythms.
Answer: The present study demonstrates that systematic MI practice in an everyday environment with a user-friendly EEG system results in MI learning effects.
Output: Does wireless EEG with individualized channel layout enable efficient motor imagery training?
