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.

Q: Context: Evidence suggests that induction of heme oxygenase-1 (HO-1) inhibits proliferation of vascular smooth muscle cells and intimal thickening after arterial injury, and therapeutic molecules induce HO-1. Probucol is the only oral drug that inhibits restenosis in humans and intimal thickening in animals, although its underlying mechanism remains unclear.', 'Aortas were harvested from New Zealand White rabbits fed normal or 0.75% (wt/wt) probucol-fortified chow, with or without endothelial denudation of the abdominal aorta on day 21, and analyzed for heme oxygenase and apoptosis. Uninjured aortas were harvested on day 21 and balloon-injured aortas on days 22 and 25. Probucol significantly increased mRNA of HO-1 assessed by real-time PCR and HO activity in aortas at all time points. Probucol also enhanced apoptosis of medial cells in the injured aorta, as evidenced by the TUNEL assay. Furthermore, probucol (100 micromol/L) increased HO-1 mRNA and HO activity when added to rabbit aortic smooth muscle cells (RASMCs) cultured in serum-free medium for 24 hours. Induction of HO-1 mRNA was inhibited by actinomycin D and was associated with inhibition of RASMC proliferation. This probucol-induced increase in HO-1 mRNA and inhibition of RASMC proliferation was prevented by the HO inhibitor Sn(IV) protoporphyrin or transfection with small interference RNA (siRNA) to knockdown HO-1, but not by inactive Cu(II) protoporphyrin or scrambled siRNA.
Answer: Probucol induces HO-1, and this contributes to the inhibition of vascular SMC proliferation. This novel finding may explain how probucol inhibits restenosis and highlights HO-1 as a target for therapeutic intervention against occlusive vascular disease.

A: Does probucol protect against smooth muscle cell proliferation by upregulating heme oxygenase-1?

Q: Context: Humans can easily restore a speech signal that is temporally masked by an interfering sound (e.g., a cough masking parts of a word in a conversation), and listeners have the illusion that the speech continues through the interfering sound. This perceptual restoration for human speech is affected by prior experience. Here we provide evidence for perceptual restoration in complex vocalizations of a songbird that are acquired by vocal learning in a similar way as humans learn their language.', "European starlings were trained in a same/different paradigm to report salient differences between successive sounds. The birds' response latency for discriminating between a stimulus pair is an indicator for the salience of the difference, and these latencies can be used to evaluate perceptual distances using multi-dimensional scaling. For familiar motifs the birds showed a large perceptual distance if discriminating between song motifs that were muted for brief time periods and complete motifs. If the muted periods were filled with noise, the perceptual distance was reduced. For unfamiliar motifs no such difference was observed.
Answer: The results suggest that starlings are able to perceptually restore partly masked sounds and, similarly to humans, rely on prior experience. They may be a suitable model to study the mechanism underlying experience-dependent perceptual restoration.

A: Does stimulus familiarity affect perceptual restoration in the European starling ( Sturnus vulgaris )?

Q: Context: Multicentric fibroadenomas, defined as multiple fibroadenomas located at different quadrants of the breast, occur in 10-20% of women with fibroadenoma. The surgical management of multicentric fibroadenomas may be troublesome for surgeons and patients. In this study, we report our preliminary experience using the "round block technique" in the management of women with multicentric fibroadenomas of the breast.', "Records of patients with breast diseases managed with the round block technique were searched for in the Changhua Christian Hospital oncoplastic breast surgery database. The patients' clinicopathologic characteristics, type of surgery, operation time, blood loss, and complications were recorded. The cosmetic outcome was evaluated by the patient and operating surgeon two months after the surgery.", 'Twenty patients with multicentric fibroadenomas managed by the round block technique comprised the current study cohort. The mean age of the subjects was 36.510.4 years. Twelve (60%) patients had tumors on one side of the breast, and eight (40%) had bilateral breast lesions. The average number of tumors removed was 3.31.2 (range 2-6) per breast, and mean tumor size was 2.20.5cm. Three (15%) patients developed mild ecchymosis of the breast undergoing operation, which resolved spontaneously. One (5%) patient had partial nipple ischemia/necrosis due to 2 tumors excised near the nipple-areolar complex. The aesthetic results were evaluated as good in 19 (95%) patients and fair in 1 (5%).
Answer: The round block technique is a useful oncoplastic procedure for the management of multicentric fibroadenomas excised at the same time.

A:
Is round block technique a useful oncoplastic procedure for multicentric fibroadenomas?
