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.

Input: Consider Input: Thyroid-stimulating hormone (TSH) levels within populations do not follow Gaussian distribution, and normal limits are derived after mathematical normalization. The clinical relevance of these limits is unknown. The objective of this study was to compare upper and lower TSH limits by four data normalization methods with non-normalized data and assess their clinical relevance.', 'Results of blood samples taken by community physicians and stored in a computerized database were analysed after removing samples from patients with evidence of thyroid illness. TSH values were normalized by the Hoffmann and Tukey methods and each method with natural log transformation. Non-normalized data for TSH in the uppermost and lowermost percentile were also calculated. Clinical relevance was determined by alterations in thyroid hormone levels at, below and above the limits for each method.', 'The maximal reduction from non-normalized data for the upper normal limit (UNL) was by the Hoffman method 43% = 3·1 mIU/l). The maximal increase for the lower normal limit (LNL) was also by the Hoffman method (708% = 0·81 mIU/l). There was very limited difference in average FT3 and FT4 between patients with TSH within, below or above the normal range for all methods.

Input: Consider Input: The extent to which tolerance acquired in one motion environment can be transferred to another has not been fully elucidated. This study compares three provocative motion stimuli and whether tolerance acquired from cross-coupled motion and torso rotation can be transferred to simulated aircraft motion.', "There were 18 healthy subjects (9 men and 9 women), 18-44 yr of age, who were divided into 3 groups. Each group was exposed to the following desensitization procedure in a pseudo-random repeated measures design. In condition D1, subjects were exposed to 4 consecutive days of cross-coupling and on the 5th d they were exposed to simulated aircraft motion. In D2, subjects were exposed to 4 consecutive days of torso rotation and on the 5th day they were exposed to the simulated aircraft motion as in D1. In D3, subjects were exposed to 5 consecutive days of simulated aircraft motion. Based on Graybiel's diagnostic criteria, severity of motion sickness on the 1st and 5th day in D1, D2, and D3 were compared.", 'Cross-coupled motion was the most provocative stimulus followed by torso rotation and simulated aircraft motion. Within each motion stimulus, there was evidence of desensitization (p < 0.001) within 4 d. There were no significant differences in the severity of motion sickness observed on the 5th day regardless of the desensitization stimuli.

Input: Consider Input: The pathogenesis of aortic dilatation in patients with congenital aortic valve anomalies is poorly understood. Recent studies suggest that alterations of gene expression may be related to ascending aortic aneurysm formation in these patients. Knockout of endothelial nitric oxide synthase (eNOS) and GATA5 is associated with bicuspid aortic valves in mice. To study the role of eNOS and GATA5 in human congenital aortic valve disease and aortic dilatation, we investigated their gene expression in aortic tissue from patients with unicuspid, bicuspid, and tricuspid aortic valves.', 'Samples from 84 patients (33 tricuspid, 32\xa0bicuspid, and 19 unicuspid) were harvested intraoperatively from the ascending aorta. GATA5 and eNOS expression was determined by real-time polymerase chain reaction.', 'GATA5 and eNOS expression in the aortic wall from patients with unicuspid aortic valves (GATA5: mean [M], 2.14; standard deviation [SD], 1.72; eNOS: M, 3.40; SD, 3.83) was significantly higher than in tricuspid aortic valves (GATA5: M, 1.12; SD, 0.80; eNOS: M, 1.00; SD, 0.74; each p < 0.05). Patients with bicuspid aortic valves (GATA5: M, 1.29, SD, 1.33; eNOS: M, 1.66; SD, 1.31) had a significantly higher eNOS expression than patients with tricuspid aortic valves (p < 0.05). The expression levels of eNOS and GATA5 correlated positively with each other and negatively with the ascending aortic diameter.
