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.
question:
Obesity has shown a positive association with depression. We aimed to investigate the relationships among body weight, body mass index (BMI=kg/m(2)), change in a depression rating scale, and change in a functional scale with fluoxetine treatment for hospitalized patients with major depressive disorder (MDD).', 'A total of 131 acutely ill inpatients with MDD were enrolled to receive 20mg of fluoxetine daily for 6 weeks. The 17-item Hamilton Depression Rating Scale (HAMD-17) for symptom and the Work and Social Adjustment Scale (WSAS) for functioning were assessed at weeks 0, 1, 2, 3, 4, and 6. Remission was defined as a score of≤7 on the HAMD-17 at endpoint. Body weight, body length, and BMI were measured at baseline. Pearson correlation coefficients (r) were calculated among body weight, BMI, HAMD-17 score change, and WSAS score change.', 'Of the 131 participants, 126 (96.2%) had at least one post-baseline assessment and were included in the analysis. Significant differences in body weight and BMI existed between remitters and nonremitters. There were statistically significant relationships among baseline body weight, baseline BMI, HAMD-17 score change, and WSAS score change at end point.

question:
Although the major limitation to exercise performance in patients with COPD is dynamic hyperinflation, little is known about its relation to daily physical activity.', 'To analyze the contribution of dynamic hyperinflation, exercise tolerance, and airway oxidative stress to physical activity in patients with COPD.', 'In a cross-sectional study, we included 110 patients with moderate to very severe COPD. Daily physical activity was measured using a triaxial accelerometer providing a mean of 1-minute movement epochs as vector magnitude units (VMU). Patients performed the 6-minute walk test, incremental exercise test with measurement of breathing pattern and operating lung volumes, and constant-work rate test at 75% of maximal work rate.', 'Using the GOLD stage and BODE index, we determined arterial blood gases, lung volumes, diffusing capacity, and biomarkers in exhaled breath condensate. Daily physical activity was lower in the 89 patients who developed dynamic hyperinflation than in the 21 who did not (n =161 [SD 70] vs. n = 288 [SD 85] VMU; P = 0.001). Physical activity was mainly related to distance walked in 6 minutes (r = 0.72; P = 0.001), Vo(2) (r = 0.63; P = 0.001), change in end-expiratory lung volume during exercise (r = -0.73; P = 0.001), endurance time (r = 0.61; P = 0.001), and 8-isoprostane in exhaled breath condensate (r = -0.67; P = 0.001). In a multivariate linear regression analysis using VMU as a dependent variable, dynamic hyperinflation, change in end-expiratory lung volume, and distance walked in 6 minutes were retained in the prediction model (r(2) = 0.84; P = 0.001).

question:
Folates provide one-carbon units for nucleotide synthesis and methylation reactions. A common polymorphism (677C-->T) in methylenetetrahydrofolate reductase (MTHFR) encodes an enzyme with reduced activity. Response to the antifolate methotrexate (MTX) may be modified in 677TT individuals because MTHFR converts nonmethylated folates, used for thymidine and purine synthesis, to 5-methyltetrahydrofolate, used in homocysteine remethylation to methionine. To study potential interactions between MTHFR activity and MTX, we examined the impact of decreased and increased MTHFR expression on MTX response in mice.', "Mthfr-deficient (Mthfr and Mthfr) and wild-type (Mthfr) mice were injected with MTX or saline and assessed for hematological parameters (hematocrit, hemoglobin, red, and white blood cell numbers), plasma homocysteine, nephrotoxicity, hepatotoxicity, and splenic 2'-deoxyuridine 5'-triphosphate/2'-deoxythymidine 5'-triphosphate ratios. MTHFR-overexpressing transgenic mice (MTHFR-Tg) were generated, metabolites and folate distributions were measured, and response to MTX was assessed.", "MTX-treated Mthfr and Mthfr mice displayed hyperhomocysteinemia and decreased hematocrit, hemoglobin, and red blood cell numbers compared with wild-type animals. Mthfr mice also showed increased nephrotoxicity and hepatotoxicity. MTHFR-Tg mice were generated and confirmed to have increased levels of MTHFR with altered distributions of folate and thiols in a tissue-specific manner. After MTX treatment, MTHFR-Tg mice exhibited the same decreases in hematological parameters as Mthfr-deficient mice, and significantly decreased thymidine synthesis (higher 2'-deoxyuridine 5'-triphosphate/2'-deoxythymidine 5'-triphosphate ratios) compared with wild-type mice, but they were protected from MTX-induced hyperhomocysteinemia.
