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.

[EX Q]: To improve prostate cancer (PC) detection accuracy among patients with a prostate-specific antigen (PSA) above 4.0 ng/ml and asymptomatic prostate inflammation.', 'A total of 136 patients with PSA ranging from 4.0 to 50.0 ng/ml with asymptomatic prostatitis were included in the study cohort. All these patients underwent antibacterial therapy for 2 weeks followed by repeat PSA determination and transrectal ultrasound-guided needle prostate biopsy. The PSA, PSAD (PSA density), and f/t PSA (free/total PSA) before and after antibacterial therapy were compared using t-test. The receiver-operating characteristic (ROC) technique was used to evaluate the effectiveness of PSA, PSAD, f/t PSA, and their changes after antibacterial therapy (DeltaPSA, DeltaPSAD, and Deltaf/t PSA) on PC detection.', 'Among the 136 patients, 33 had PC and the other 103 histologically confirmed benign prostatic disease. After antibacterial therapy for 2 weeks, the PSA (mean +/- standard deviation) decreased from 14.0 +/- 7.8 ng/ml to 10.4 +/- 7.7 ng/ml (P < 0.01). The DeltaPSA, DeltaPSAD, and Deltaf/tPSA were -3.60 +/- 4.3 ng/ml, -0.1 +/- 0.1 ng/ml/ml, and -0.1 +/- 0.1 respectively. The areas under ROC curve were 0.29 for PSA, 0.64 for PSAD, and 0.50 for f/t PSA. The areas under ROC curve were 0.91 for DeltaPSA, 0.96 for DeltaPSAD, and 0.98 for Deltaf/t PSA. These values were increased significantly when compared with those for the PSA-related parameters before antibacterial therapy (P value, DeltaPSA, DeltaPSAD, and Deltaf/t PSA were <0.01).

[EX Q]: As a component of the outer membrane in Gram-negative bacteria, lipopolysaccharide (LPS)-induced proliferation and cell cycle progression of monocytes/macrophages. It has been suggested that the proapoptotic T-cell death-associated gene 51 (TDAG51) might be associated with cell proliferation and cell cycle progression; however, its role in the interaction between LPS and macrophages remains unclear.', 'We attempted to elucidate the role(s) of TDAG51 played in the interaction between LPS and macrophages.', 'We investigated TDAG51 expression in RAW264.7 cells stimulated with LPS and examined the effects of RNA interference-mediated TDAG51 down-regulation. We used CCK-8 assay and flow cytometry analysis to evaluate the interaction between TDAG51 and LPS-induced proliferation and cell cycle progression in RAW264.7 cells.', 'Our findings indicate that TDAG51 is up-regulated in LPS-stimulated RAW264.7 cells, the TDAG51 siRNA effectively reduced TDAG51 protein up-regulation following LPS stimulation in RAW264.7 cells, the significant changes of the proliferation and cell cycle progression of RAW264.7 cells in TDAG51 Knockdown RAW264.7 cells treated with LPS were observed.

[EX Q]: Excessive infant crying, or infantile colic, is a common and often stress-inducing problem for parents that can ultimately result in child abuse. From previous research it is known that maternal depression is related to excessive crying, but so far little is known about the influence of paternal depression.', "In a prospective, population-based study, we obtained information on both maternal and paternal depressive symptoms at 20 weeks of pregnancy by using the Brief Symptom Inventory. Parental depressive symptoms were related to excessive crying in 4426 two-month-old infants. The definition of excessive crying was based on the widely used Wessel's criteria (ie, crying >3 hours for >3 days in the past week).", 'After adjustment for depressive symptoms of the mother and relevant confounders, we found a 1.29 (95% confidence interval: 1.09-1.52) higher risk of excessive infant crying per SD of paternal depressive symptoms.
