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.

Ex Input:
Williams syndrome (WS), a genetic disorder resulting from hemizygous microdeletion of chromosome 7q11.23, has emerged as a model for identifying the genetic architecture of socioemotional behavior. Common polymorphisms in GTF2I, which is found within the WS microdeletion, have been associated with reduced social anxiety in the general population. Identifying neural phenotypes affected by these polymorphisms would help advance our understanding not only of this specific genetic association but also of the broader neurogenetic mechanisms of variability in socioemotional behavior.', 'Through an ongoing parent protocol, the Duke Neurogenetics Study, we measured threat-related amygdala reactivity to fearful and angry facial expressions using functional magnetic resonance imaging, assessed trait personality using the Revised NEO Personality Inventory, and imputed GTF2I rs13227433 from saliva-derived DNA using custom Illumina arrays. Participants included 808 non-Hispanic Caucasian, African American, and Asian university students.', 'The GTF2I rs13227433 AA genotype, previously associated with lower social anxiety, predicted decreased threat-related amygdala reactivity. An indirect effect of GTF2I genotype on the warmth facet of extraversion was mediated by decreased threat-related amygdala reactivity in women but not men.

To determine the impact of the time interval from the end of sperm preparation (TSP) to intrauterine insemination (IUI) on the outcome.', 'Prospective multicentre cohort study.', 'Seven French centers (assisted reproduction group in northeastern France, four academic centers, and three clinics).', 'Eight hundred sixty-two IUI cycles (709 patients) managed by gonadotropins were studied.', 'Cycles were stimulated by either FSH or hMG, and hCG was administrated when the leading follicle diameter measured >15 mm. IUIs were performed ∼ 36 hours after ovulation triggering.', 'Generalized linear mixed models for binary outcomes were used to model clinical pregnancy (CP) to assess the effect of TSP adjusted for other predictors (such as maternal age, semen quality, and indication of IUI treatment).', 'The TSP effect was significant, featuring an inverse U-shaped curve admitting an optimum interval of ∼ 40-80 minutes improving CP compared with other values. Other significant predictors were total motile spermatozoa inseminated, maternal age, and unexplained infertility.

Ex Output:
Is clinical success of intrauterine insemination cycles affected by the sperm preparation time?


Ex Input:
Acute rejection (AR) after organ transplantation results in transplant arteriosclerosis (TA). Endothelial progenitor cells (EPCs) are involved in tissue repair and blood vessel formation but are suspected to be a cause of TA.', 'In this study, we introduced a syngeneic and allogeneic abdominal aortic transplant model with C57BL/6 and BALB/c mice. Syngeneic and allogeneic grafts were histopathologically analyzed after transplantation. Bone marrow-derived EPCs were injected into transplant model animals to observe their distribution and temporal concentration changes. Changes of vascular endothelial growth factor receptor 1 (VEGFR-1), phosphorylated VEGFR-1 (pVEGFR-1), VEGFR-2, pVEGFR-2, protein kinase B (Akt), pAkt, extracellular signal-regulated kinase 1 (Erk1), pErk1 levels in EPCs upon VEGF165 and the VEGFR inhibitor Vandetanib exposure were analyzed in\xa0vitro with western blotting.', 'In the allogeneic transplant group, two weeks after transplantation, formations of new intima layers could be observed, and its proliferation gradually increased to four and six weeks post-transplantation (p\xa0<\xa00.05), accompanied by significant arterial stenoses. Exogenous EPCs mainly localized to the damaged sites of the transplant arteries. In\xa0vivo, Vandetanib caused a significant dose dependent decrease of transplant hyperplasia (p\xa0<\xa00.05) and inhibited VEGF related proliferation, migration and adhesion of EPCs.
