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: Oral tacrolimus, approved for the prophylaxis of organ rejection in liver or kidney transplants, has been reported to be effective in anecdotal cases of refractory inflammatory bowel disease.', 'To evaluate the usefulness of low-dose oral tacrolimus in refractory inflammatory bowel disease.', "Thirty-one adult Caucasian patients with steroid-dependent (n = 15) or steroid-refractory (n = 16) inflammatory bowel disease (Crohn's disease, n = 6; ulcerative colitis, n = 23; pouchitis, n = 2) were enrolled. Tacrolimus (0.1 mg/kg body weight per day) was administered orally in 30 patients and initially intravenously in one patient (0.01 mg/kg body weight per day), aiming for serum trough levels of 4-6 ng/mL. The median treatment duration was 12 months (range, 1-137 months).", "Twenty-eight patients (90.3%) experienced a clinical and laboratory response and 20 (64.5%) went into remission. One ulcerative colitis patient and two Crohn's disease patients did not improve. Three ulcerative colitis patients (9.7%) were colectomized at 1, 12 and 24 months after tacrolimus initiation. In 19 of 23 patients (82.6%) taking steroids, steroids were reduced or discontinued. Side-effects included a temporary rise of creatinine (n = 3, 9.7%), tremor or paraesthesias (n = 3, 9.7%), hyperkalaemia (n = 1, 3.2%), hypertension (n = 1, 3.2%) and an opportunistic infection (n = 1, 3.2%).\Question: Is rescue therapy with tacrolimus effective in patients with severe and refractory inflammatory bowel disease?
Example Output: Oral tacrolimus is safe and effective in refractory inflammatory bowel disease.

Example Input: Context: To investigate whether intracavitary physiotherapy is superior to endometrial scratching in patients with recurrent implantation failure (RIF) after in vitro fertilization/intracytoplasmic sperm injection- embryo transfer (IVF/ICSI-ET) cycles.', 'According to the inclusion criteria defined by our hospital, 63 patients with RIF were included in the retrospective study. 20 patients who received intracavitary physiotherapy were classified into Group A, 8 patients with both intracavitary physiotherapy and endometrial scratching were into Group B, and 35 patients who underwent endometrial scratching were into Group C. The primary outcome measures were implantation and clinical pregnancy rates. The secondary outcome measure was pregnancy outcome.', 'There were no statistical differences in implantation and clinical pregnancy rates between Groups A and C (29.41 vs 35.59 %, 45.00 vs 48.57 % respectively, P > 0.05), Groups B and C (36.36 vs 35.59 %, 50.00 vs 48.57 % respectively, P > 0.05). In addition, no statistical differences were discovered in pregnancy outcomes between Groups A and C (P > 0.05), Groups B and C (P > 0.05).\Question: Is intracavitary physiotherapy inferior to endometrial scratching in patients with recurrent implantation failure?
Example Output: Intracavitary physiotherapy is not inferior to endometrial scratching on improving implantation and clinical pregnancy rates in patients with RIF after IVF/ICSI cycles.

Example Input: Context: The hypothesis that in normotensive offspring of hypertensive parents exercise training could influence the systemic release of endothelin (ET)-1 during a provocative testing protocol was tested.', 'The provocative handgrip test was performed in four groups of healthy young age-matched males: offspring of hypertensive parents following a regular swimming exercise regimen (group A, n = 14); offspring of hypertensive parents and leading a sedentary lifestyle (group B, n = 11); normal volunteers with no family history of hypertension: sedentary (group C, n = 10), and following a regular swimming regimen (group D, n = 10). The plasma ET-1 was measured at baseline, after 4 min of handgrip exercise at 50% maximal capacity and following 2 (R2) and 10 (R10) min of recovery from handgrip.', 'ET-1 plasma levels, within the normal range in all groups at baseline (group A 0.94 +/- 0.32 pg/ml, group B 0.84 +/- 0.26 pg/ml, group C 0.78 +/- 0.35 pg/ml, group D 0.85 +/- 0.26, p = NS) showed a progressive and significant increase in group B during and after handgrip exercise (peak handgrip 1.08 +/- 0.5 pg/ml, p = NS; R2 1.35 +/- 0.36 pg/ml, p < 0.05; R10 2.76 +/- 0.75 pg/ml, p < 0.01). Significant differences were found at R2 and R10 when the ET-1 levels measured in group B were compared to those observed in group A, group C and group D. Multivariate analysis demonstrated that the serum levels of ET-1 significantly contributed to predict handgrip-induced changes when the diastolic blood pressure was the dependent variable.\Question: Does exercise training counteract the abnormal release of plasma endothelin-1 in normal subjects at risk for hypertension?
Example Output:
Routine aerobic exercise appeared to counteract the handgrip-induced abnormal release of plasma ET-1 and may favorably affect the preclinical endothelial alterations seen in healthy offspring of hypertensive parents.
