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: The effects of exercise training on LV remodelling following large anterior myocardial infarction (MI) remains controversial. Blockade of the renin-angiotensin system has been shown to prevent ventricular dilation and deleterious remodeling. We therefore tested, in a rat model of chronic MI, whether any potentially deleterious effects of exercise on post-MI remodelling could be ameliorated by angiotensin II receptor blockade.', 'Male Wistar rats underwent coronary ligation or sham operation. Treatment with losartan (10 mg/kg/day) began 1 week post-MI and moderate treadmill exercise (25 m/min, 60 min/day, 5 days/week) was initiated 2 weeks post-MI. Systolic and diastolic pressure-volume relationships were measured in isolated, red-cell perfused, isovolumically beating hearts 8 weeks post-MI. Morphometric measurements were performed in trichrome stained cross sections of the heart. Five groups of animals were compared: sham (n=13), control MI (MI; n=11), MI plus losartan (MI-Los; n=13), MI plus exercise (MI-Ex; n=10) and MI plus exercise and losartan (MI-Ex-Los; n=12).', 'Infarct size (% of left ventricle, LV) was similar among the infarcted groups [MI=43+/-4%, MI-Los=49+/-2%, MI-Ex=45+/-1%, MI-Ex-Los=48+/-2% (NS)]. Exercise, losartan and exercise+losartan treatments all attenuated LV dilation post-MI to a similar degree. Exercise training increased LV developed pressure in both untreated and losartan treated hearts (P<0.05 vs. other MI groups). In addition, exercise resulted in additional scar thinning in untreated hearts, while no additional scar thinning was seen in post-infarct hearts receiving both losartan and exercise.
Example Output: Does angiotensin II receptor blockade attenuate the deleterious effects of exercise training on post-MI ventricular remodelling in rats?

Example Input: Complex regional pain syndrome (CRPS) is a painful condition with approximately 50,000 annual new cases in the United States. It is a major cause of work-related disability, chronic pain after limb fractures, and persistent pain after extremity surgery. Additionally, CRPS patients often experience cognitive changes, anxiety, and depression. The supraspinal mechanisms linked to these CRPS-related comorbidities remain poorly understood.', 'The authors used a previously characterized mouse model of tibia fracture/cast immobilization showing the principal stigmata of CRPS (n = 8 to 20 per group) observed in humans. The central hypothesis was that fracture/cast mice manifest changes in measures of thigmotaxis (indicative of anxiety) and working memory reflected in neuroplastic changes in amygdala, perirhinal cortex, and hippocampus.', 'The authors demonstrate that nociceptive sensitization in these mice is accompanied by altered thigmotactic behaviors in the zero maze but not open field assay, and working memory dysfunction in novel object recognition and social memory but not in novel location recognition. Furthermore, the authors found evidence of structural changes and synaptic plasticity including changes in dendritic architecture and decreased levels of synaptophysin and brain-derived neurotrophic factor in specific brain regions.
Example Output: Do brain neuroplastic changes accompany anxiety and memory deficits in a model of complex regional pain syndrome?

Example Input: To investigate changes in autoreactive T-cell responses against PMP-22 and P2 antigen as well as a T-cell memory repertoire in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) induced by repeated intravenous immunoglobulin (IVIg) treatment.', 'In an observational trial, we prepared cryopreserved human peripheral blood monocytes from blood from 34 patients with CIDP (18 treatment naïve and 16 maintenance IVIg treatment) and from 14 healthy controls (non-immune neuropathy and healthy control). Treatment response was defined by clinical evaluation. The autoantigen-specific T-cell response was analysed by enzyme linked immunosorbent spot (ELISPOT) assay before IVIg start (baseline) and at follow-up. The T-cell memory subsets were analysed by using flow cytometric analysis.', 'Myelin-derived P2-specific and PMP-22-specific IFN-γ producers were increased in IVIg responders compared with non-responders before treatment, which decreased by repeated IVIg infusion cycles. Treatment responders but not non-responders showed higher frequencies of CD4 T effector memory (TEM) and T central memory frequencies at baseline compared with maintenance IVIg treatment patients and controls. In addition, IVIg treatment was associated with a significant reduction in CD8 TEM at follow-up.

Does effective treatment with intravenous immunoglobulins reduce autoreactive T-cell response in patients with CIDP?
