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: Enterovirus infections are major etiological factors in myocarditis and dilated cardiomyopathy. Using an experimental murine model of this disease, previous studies have shown that myocarditis susceptibility depends upon activation of T lymphocytes expressing the gamma delta T cell receptor (TcR), and that only mouse strains which accumulate gamma delta T cells in the myocardium show apoptosis of myocytes or evidence of dilated cardiomyopathy-like disease. The objective of the present studies is to demonstrate that gamma delta T cells directly induce greater Fas-dependent apoptosis of cultured myocytes than T cells expressing the alpha beta TcR.', 'Bl.Tg.E alpha mice were infected for 7 days with coxsackievirus B3 (CVB3). Hearts were removed and were either formalin-fixed, sectioned and stained with hematoxylin and eosin for inflammation, and using TdT-TUNEL for apoptosis, or were minced and collagenase digested for isolation of gamma delta+ and alpha beta+ T cells using immunomagnetic bead separation. Neonatal cultures of cardiac myocytes were isolated from mice less than 2 days old by collagenase and pancreatin digestion, and were either untreated or infected with virus. Levels of Fas (CD95) were measured using FITC-conjugated hamster anti-mouse Fas monoclonal antibody and flow cytometry. Susceptibility of myocytes to Fas-dependent killing was measured by 51Cr-release by labeled myocytes incubated for 4 h on either 3T3-mock or 3T3-FasL transfected cell monolayers. Killing by T cells was also measured in a 4 h 51Cr-release assay. Fas-dependent and perforin-dependent cytotoxicity was determined by specific blocking using either Fas-Fc or concanamycin A.', 'Virally infected myocyte cultures showed significantly enhanced Fas expression compared to uninfected cells, with maximal upregulation of Fas occurring 18-24 h after virus infection. Both infected and uninfected myocytes were selectively killed by FasL-transfected 3T3 cells but not by mock control cells. Approximately 38% of CD3+ lymphocytes isolated from the heart express the gamma delta TcR with the remainder expressing the alpha beta TcR. Both gamma delta+ and alpha beta+ T cells lysed myocyte targets. Blocking studies indicate that gamma delta+ T cells induced predominantly Fas-mediated killing, while alpha beta+ cell produced more perforin-mediated death, although these effectors were capable of Fas-dependent killing as well.\Question: Do t cells expressing the gamma delta T cell receptor induce apoptosis in cardiac myocytes?
Example Output: These studies demonstrate that T cells expressing the gamma delta TcR are more effective mediators of myocyte apoptosis than alpha beta+ T cells in vitro and suggests that these effectors may be primarily responsible for myocardial injury associated with dilated cardiomyopathy-like signs during coxsackievirus B3-induced myocarditis.

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: Reabsorption of bile acids from the intestine by ileal bile acid transporter is pivotal for the enterohepatic circulation of BAs and sterol homoeostasis.', 'To assess tolerability and study, bile acid metabolism in a phase 1 trial with the selective ileal bile acid transporter inhibitor A4250.', 'A randomised double-blind, single-ascending dose (SAD) and multiple-ascending-dose study consisting of five cohorts comprising 40 individuals with a single administration of A4250 (0.1, 0.3, 1, 3, or 10mg) or placebo and three cohorts comprising 24 individuals with a 1-week administration of A4250 (1 or 3mg once daily or 1.5mg twice daily) or placebo. For the multiple-ascending-dose study, bile acids were measured by HPLC-MS in plasma and faeces, and fibroblast growth factor 19 (FGF19) and 7-hydroxy-4-cholesten-3-one (C4) were measured in plasma.', 'No serious adverse events occurred and all participants finished the trial per protocol. At the end of the multiple-ascending-dose study, plasma total bile acids and FGF19 decreased by 47% and 76%, respectively, at 3mg/day (P<0.01), and by 15% and 16%, respectively, at 1.5mg twice daily (P<0.05). Plasma C4 and faecal bile acids increased at all dose regimens, by 555%, 664%, 292% and 338%, 421%, 420%, respectively (P<0.01-0.05). The primary bile acids cholic and chenodeoxycholic acids constituted the majority of faecal bile acids in the A4250-treated groups.\Question: Does the ileal bile acid transporter inhibitor A4250 decrease serum bile acids by interrupting the enterohepatic circulation?
Example Output:
A4250 is well tolerated. By blocking ileal bile acid transporter in the terminal ileum, it highly efficiently interrupts the enterohepatic circulation of BAs, and should be of benefit to patients with cholestatic liver diseases. Clinical Trial registration EudraCT 2013-001175-21.
