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.

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.

Does angiotensin II receptor blockade attenuate the deleterious effects of exercise training on post-MI ventricular remodelling in rats?

To observe the effects of Sanhuangyinchi decoction (SHYCD) pretreatment on acute hepatic failure (AHF) induced by D-galactosamine and lipopolysaccharide (LPS) in rats and explore the possible mechanisms involving antioxidant stress and cell apoptosis-related protein expression.', 'Forty-eight SD rats were randomized equally into control group, AHF model group, high-, medium- and low-dose SHYCD groups, and Bicyclol group. Five days after administration of the corresponding drugs, the rats were challenged with peritoneal D-galactosamine (700 mg/kg) plus LPS (10 ug/kg) injections to induce AHF acute hepatic failure except for those in the control group. At 48 h after the injections, blood samples were collected from the rats to detect the levels of ALT, AST, TBIL, PT, INR and FIB, and pathological changes and superoxide dismutase (SOD) and malondialdehyde (MDA) contents in the liver were examined; immunohistochemistry and western blotting were used to detect caspase-3 protein expression in the liver.', 'The levels of ALT, AST, TBIL, TP and INR in the 3 SHYCD groups and Bicyclol group significantly decreased (P<0.05) while FIB significantly increased in comparison with those in the model group. SHYCD obviously ameliorated the pathological changes, enhanced SOD activity (P<0.05), and decreased MDA levels (P<0.05) and caspase-3 expression (P<0.05) in the liver tissue. SHYCD at the medium dose produced similar effects to Bicyclol (P>0.05) and showed better effects at the high dose than Bicyclol (P<0.05).

This research note discusses a common misconception in speech science and speech-language pathology textbooks that rib torque (i.e., rotational stress) assists resting tidal expiration and conversational speech production.', 'The nature of this misconception is considered.

Ex Output:
Does rib torque assist resting tidal expiration or most conversational speech expiration?
