In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: To assess the relationship between congenital uterine malformations and blood pressure in pregnancy.', 'Twenty-four-hour automated ambulatory blood pressure monitoring (readings every 30 min) was performed in 16 normotensive, nonproteinuric, primigravidae with congenital uterine malformations (5 uterus septus, 9 uterus bicornis, 2 uterine didelphys) between 20 and 30 weeks. From the 24-hr blood pressure report, we calculated 24-hr mean, daytime and nighttime means. The results were compared with 16 primigravidae, matched for age and gestation, who were and remained normotensive throughout pregnancy, and tested for statistics with t-test; significance assessed at p < 0.001.', 'Although they were within the normotensive range, all blood pressure measurements considered were significantly higher in pregnant women with congenital uterine malformations, compared to normal pregnant women. Namely, 24-hr, daytime, and nighttime systolic (mean +/- SD) were 121.1 +/- 8.4, 124.4 +/- 8.8, 114.0 +/- 7.7 mmHg, respectively, in women with uterine malformations and 108.0 +/- 7.4, 109.2 +/- 7.3, 102.1 +/- 8.5 mmHg, respectively, in normal pregnant women. Twenty-four-hour diastolic, daytime, and nighttime diastolic (mean +/- SD) 74.1 +/- 10.2, 77.1 +/- 10.6, 68.1 +/- 9.2 mmHg, in women with uterine malformations and 64.1 +/- 5.7, 66.0 +/- 5.7, 58.2 +/- 6.3 mmHg, in normal pregnant women (all differences p < 0.001). Fifteen of the fetuses from women with congenital uterine malformations showed intrauterine growth retardation. No differences were found 6 months after delivery.\Question: Are congenital uterine malformations associated to increased blood pressure in pregnancy?
Example Output: Although the blood pressure levels remained within the normotensive range, pregnant women with congenital uterine anomalies have a higher blood pressure than normal women. Elevated blood pressure can result from altered uterine circulation and reduced blood supply to the placenta. This pathogenesis or the poor placentation may result in a foetal growth retardation.

Example Input: Context: To determine whether repeat administration of an adenovector (Ad) into the eye results in efficient gene delivery and to test whether transgenes can be expressed from an adenovector expression system in the presence of preexisting, neutralizing anti-Ad antibodies.', 'To assess the efficiency of repeated gene delivery of an adenovector expression system, C57Bl/6 mice received one, two, or three injections (intravitreal [IVT] or periocular [PO]) of AdNull.11D (empty cassette) at 2-week intervals, followed by a single AdLuciferase (AdL.11D) IVT or PO injection. Mice were killed approximately 24 hours after AdL.11D injection and the eyes were enucleated and stored until assayed. Serum samples were also analyzed to determine whether repeated IVT or PO injections lead to induction of neutralizing antibodies directed against an adenovector delivery system. To determine whether preexisting neutralizing anti-Ad antibodies would block transgene expression, mice were preimmunized with one, two, or three intramuscular (IM) injection(s) of AdNull.11D (1 x 10(9) particle units [pu]). Fourteen days later, when systemic anti-Ad antibody titers were expected to exist, mice were given a single AdL.11D injection (IVT or PO) and killed, and the eyes and serum collected.', 'These studies show that multiple injections at 2-week intervals with adenovectors (IM, IVT, or PO) did not prevent transgene expression in the eye. Moreover, measurement of neutralizing anti-Ad antibody titers revealed that measurable anti-Ad antibody titers in mice did not ablate transgene expression.\Question: Does repeated administration of adenovector in the eye result in efficient gene delivery?
Example Output: These studies suggest that transgene expression after repeated adenovector administration into the eye is feasible and repeated injections, whether given IVT or PO, do not lead to an immediate increase in neutralizing anti-Ad antibody titers. Moreover, preimmunization of mice by systemic exposure to adenovector, does not block transgene expression in the eye. These studies indicate that repeat administration of adenovectors (IVT and PO) into the eye can be considered in designing future clinical trials and that the pre-existence of neutralizing anti-Ad antibodies probably does not mitigate activity.

Example Input: Context: Hyperhomocysteine is an independent risk factor of coronary heart disease (CHD). However, whether hyperhomocysteine affects the progression of atherosclerosis is unclear. In the present study, we examined the effect of hyperhomocysteine on the formation of atherosclerosis in low-density lipoprotein receptor-deficient (LDLr(-/-)) mice.', 'Forty-eight 7-week-old LDLr(-/-) mice were assigned to the following groups: mice fed a standard rodent diet (control group), mice fed a high-methionine diet (high-methionine group), mice fed a high-fat diet (high-fat group), and mice fed a diet high in both methionine and fat (high-methionine and high-fat group). At the age of 19, 23, and 27 weeks, four mice at each interval in every group were sacrificed.', 'At the end of the study, mice did not show atherosclerotic lesions in the aortic sinus and aortic surface until 27 weeks old in the control group. However, atherosclerotic lesions developed in the other three groups at 19 weeks. The amount of atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group (P < 0.001). Atherosclerotic lesions on the aortic surface in the high-methionine and high-fat group were the most severe. The mean area of atherosclerotic lesions in the aortic sinus compared with atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group (P < 0.001). Atherosclerotic lesions in the aortic sinus in the high-methionine and high-fat group were the most severe.\Question: Does hyperhomocysteinemia independently cause and promotes atherosclerosis in LDL receptor-deficient mice?
Example Output:
Homocysteinemia accelerates atherosclerotic lesions and induces early atherosclerosis independently in LDLr(-/-) mice. Reducing the level of homocysteinemia may be beneficial for prevention and treatment of CHD.
