Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Accurate prediction of recovery of dysfunctional myocardium would optimize risk/benefit analysis among patients with coronary artery disease and decreased ventricular function. Tissue-tagged magnetic resonance imaging permits quantitative assessment of changes in ventricular function and may improve the prediction of myocardial recovery after coronary artery bypass grafting.', 'Thirteen patients underwent preoperative and postoperative stress magnetic resonance imaging with strain analysis at rest with 5 and 10 microg x kg(-1) x min(-1) dobutamine. Two-dimensional strain analysis was performed on a single midventricular short-axis image divided into 6 regions for each patient (n = 78). Regional minimum principal, circumferential, and radial strain values were calculated at each stress level. Regional changes in postoperative strain were correlated with changes in preoperative dobutamine stress by means of logistic regression. Receiver operating characteristic curves were created to determine the accuracy of preoperative dobutamine stress for the prediction of postoperative myocardial recoverability.', 'Minimum principal, circumferential, and radial strain values at 5 and 10 microg of dobutamine differed significantly from baseline strains (P < .05). Receiver operator characteristic curves found minimum principal strain to be 75% accurate for prediction of recoverability at both stress levels. Circumferential strain was 72% and 70% accurate at 5 and 10 microg, respectively, whereas radial strain was 77% and 64% accurate at 5 and 10 microg, respectively.

Intermountain Risk Score (IMRS) uses the admission complete blood count and basic metabolic profile to predict mortality. Intermountain Risk Score has been validated in medical patients but has not been evaluated in trauma. This study tested whether IMRS is predictive of mortality in a trauma population at a level I trauma center.', 'Admitted trauma patients with complete blood count and basic metabolic profile from October 2005 to December 2011 were evaluated. Thirty-day and 1-year IMRS were calculated using multivariable modeling. Mortality was determined using the medical record and Social Security Administration death data.', 'Three thousand six hundred thirty-seven females and 5901 males were evaluated. Intermountain Risk Score was highly predictive of death at 30 days (c-statistics, c = 0.772 for females; c = 0.783 males) and 1 year (c = 0.778 for females; c = 0.831 males). Cox regression analysis, adjusted for injury severity score, blunt vs penetrating, and length of stay, showed increased mortality risks among patients in the moderate- and high-risk IMRS-defined groups at both 30 days and 1 year, with hazard ratios ranging from 4.96 to 57.88 (all P < .001).

To evaluate the effect of Ac-hE-18A-NH2 on TNF- secretion and mRNA expression in ox-LDL-stimulated RAW264.7 macrophages and to elucidate the possible mechanisms.', "Macrophages were incubated in the medium containing various concentrations of Ac-hE18A-NH2 (1-50 g/mL) with ox-LDL (50 g/mL) stimulated. The TNF- level and intracellular cholesterol content were measured by commercially available quantitation kits following the manufacturer's instructions. TNF- and ATP-binding cassette transporter A1 (ABCA1) mRNA expression were detected by real-time PCR. ABCA1 and IB protein -expression in the macrophages were determined by Western blot. NF-B activity was evaluated by electrophoretic mobility shift assay (EMSA).", 'Ox-LDL stimulation induced a significant increase in TNF- secretion, mRNA expression, cholesterol accumulation and nuclear factor-B (NF-B) activity in RAW264.7 macrophages. Ac-hE-18A-NH2 reduced TNF- secretion and mRNA expression, up-regulated the ABCA1 mRNA and protein expression, reduced the intracellular cholesterol content, and inhibited NF- B activation in a dose-dependent manner. Under the same condition and the same concentration, Ac-hE-18A-NH2 was more efficient than D-4F (apoA-I mimetic peptide) in inhibiting the inflammatory response induced by ox-LDL in the macrophages.
