Given a passage, 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.

Example Input: Left ventricular aneurysm repair (LVR) reduces LV wall stress and improves LV function. However, as we reported previously, the initial improvement of LVR was short-term because of LV remodeling but could be maintained longer with postoperative use of an angiotensin-converting enzyme (ACE) inhibitor. Atrial natriuretic peptide (ANP) has been used to treat patients with heart failure by natriuretic and vasodilatory actions. Recent reports have suggested that ANP inhibits the rennin-angiotensin system. In this study, the effects of ANP after LVR were evaluated.', 'Rats that had an LV aneurysm 4 weeks after left anterior descending artery ligation underwent LVR by plicating the LV aneurysm and were randomized into 2 groups: LVR+A group was intravenously administrated with 10 microg/h of carperitide, recombinant alpha-hANP, by osmotic-pump for 4 weeks, and the LVR group was given normal saline. Echocardiography revealed better LV remodeling and function in LVR+A group than in LVR group. Four weeks after LVR, left ventricular end diastolic pressure (LVEDP) and Tau were significantly lower in LVR+A group (LVEDP: 10+/-4 in LVR+A group versus 18+/-6 mm Hg in LVR group, Tau: 13+/-2 versus 17+/-2ms). End-systolic elastance (Ees) was higher in LVR+A group (Ees: 0.34+/-0.2 versus 0.19+/-0.11 mm Hg/microL). The levels of myocardial ACE activity in LVR+A group was significantly lower than in LVR group. The mRNA expressions of brain natriuretic peptide and transforming growth factor beta1 inducing fibrosis significantly decreased in LV myocardium in LVR+A group. Histologically, myocardial fibrosis was significantly reduced in LVR+A group.
Example Output: Does atrial natriuretic peptide help prevent late remodeling after left ventricular aneurysm repair?

Example Input: The role of sleep in the enhancement of motor skills has been studied extensively in adults. We aimed to determine involvement of sleep and characteristics of spindles and slow waves in a motor skill in children.', 'We hypothesized sleep-dependence of skill enhancement and an association of interindividual differences in skill and sleep characteristics.', '30 children (19 females, 10.7 0.8 years of age; mean SD) performed finger sequence tapping tasks in a repeated-measures design spanning 4 days including 1 polysomnography (PSG) night. Initial and delayed performance were assessed over 12 h of wake; 12 h with sleep; and 24 h with wake and sleep. For the 12 h with sleep, children were assigned to one of three conditions: modulation of slow waves and spindles was attempted using acoustic perturbation, and compared to yoked and no-sound control conditions.', 'Mixed effect regression models evaluated the association of sleep, its macrostructure and spindles and slow wave parameters with initial and delayed speed and accuracy.
Example Output: Do sleep spindle and slow wave frequency reflect motor skill performance in primary school-age children?

Example Input: Calcipotriol ameliorates psoriasis through inducing keratinocyte apoptosis and inhibiting nuclear factor kappa B (NF-B) activation, while zinc finger protein A20 exhibits an anti-apoptotic effect on various types of cells.', 'To understand the potential role of A20 in calcipotriol function.', 'The A20 levels were evaluated in the psoriatic skins from both human patients and K14-vascular endothelial growth factor (VEGF) transgenic mice that received or did not receive topical calcipotriol treatment. The in vitro effect of calcipotriol on A20 expression and the downstream NF-B pathway was studied using a model of human foreskin keratinocytes (HFKs) that were stimulated with psoriatic cytokines [M5, a cocktail of interleukin (IL)-1a, IL-17A, IL-22, Oncostatin M and tumour necrosis factor-, each at 10 ng mL(-1) ].', 'A20 expression was enhanced in both psoriatic tissues and keratinocytes when compared with controls, but decreased on calcipotriol treatment. The transfection of A20 small interfering RNA (siRNA) improved cell differentiation, and inhibited psoriatic inflammation in a HFK model. Moreover, the nuclear expression of NF-B p65 decreased on A20 downregulation in psoriatic tissues and keratinocytes. Interestingly, calcipotriol enhanced the binding of A20 to ring finger protein 114 (RNF114) and A20-binding inhibitor of NF-B-1 (ABIN-1) in HFKs, two negative regulators of the NF-B pathway.
Example Output:
Is zinc finger protein A20 involved in the antipsoriatic effect of calcipotriol?
