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.

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).

Airway hyperresponsiveness (AHR) is associated with persistent air flow limitation and accelerated FEV(1) decline. AHR can influence diagnosis, treatment, and prognosis. We assessed the value of pulmonary function variables, symptoms, and history as selection criteria for methacholine bronchoprovocation testing to detect AHR in symptomatic subjects.', 'Over a 4-year period we conducted a prospective study of consecutive subjects who underwent methacholine bronchoprovocation testing. Baseline pulmonary function testing (PFT) and a questionnaire were obtained prior to methacholine bronchoprovocation testing. PFT and symptom and history variables were assessed as AHR predictors in univariate and multiple logistic regression analyses for the whole group and for 4 different age groups.', 'There were 530 subjects, with ages ranging from 5 to 87 years, and 232 (44%) were positive for methacholine AHR. AHR was more prevalent among subjects < or = 25 years old (59%) and > 65 years old (47%) than among the other age groups. PFT values, symptom, and history variables had different AHR predictive values among the different age groups. Symptom and history variables had no AHR predictive value among subjects < or = 25 or > 65 years old.

Ex Input:
Plant genomes are populated by different types of repetitive elements including transposable elements (TEs) and simple sequence repeats (SSRs) that can have a strong impact on genome size and dynamic as well as on the regulation of gene transcription. At least two-thirds of the tomato genome is composed of repeats. While their bulk impact on genome organization has been recently revealed by whole genome assembly, their influence on tomato biology and phenotype remains largely unaddressed. More specifically, the effects and roles of DNA repeats on the maturation of fleshy fruits, which is a complex process of key agro-economic interest, still needs to be investigated comprehensively and tomato is arguably an excellent model for such study.', 'We have performed a comprehensive annotation of the tomato repeatome to explore its potential impact on tomato genome composition and gene transcription. Our results show that the tomato genome can be fractioned into three compartments with different gene and repeat density, each compartment presenting contrasting repeat and gene composition, repeat-gene associations and different gene transcriptional levels. In the context of fruit ripening, we found that repeats are present in the majority of differentially methylated regions (DMRs) and thousands of repeat-associated DMRs are found in gene proximity including hundreds that are differentially regulated. Furthermore, we found that repeats are also present in the proximity of binding sites of the key ripening protein RIN. We also observed that some repeat families are present at unexpected high frequency in the proximity of genes that are differentially expressed during tomato ripening.
