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.

Example Input: We have previously demonstrated that sophorolipids, a class of easily chemoenzymatically modifiable glycolipids, possess anti-inflammatory effects in vitro and in vivo. Since glycolipids have been shown to have anticancer activity, we investigated the effects of sophorolipids and their derivatives against pancreatic cancer.', 'Human pancreatic carcinoma cells were treated with increasing concentrations of sophorolipid natural mixture or select derivatives (ethyl ester, methyl ester, ethyl ester monoacetate, ethyl ester diacetate, acidic sophorolipid [AS], lactonic sophorolipid diacetate [LSD]) for 24 h and assessed for cell necrosis (cytotoxicity-lactate dehydrogenase release). Controls consisted of cells treated with media or vehicle alone and sophorolipid treatment of peripheral blood mononuclear cells.', 'Sophorolipids demonstrated anticancer activity against human pancreatic carcinoma cells. Natural mixture mediated consistent cytotoxicity at all doses tested (20 +/- 4%). However, methyl ester derivative mediated much greater levels of cytotoxicity (63 +/- 5%) compared with other derivatives (ethyl ester diacetate, 36 +/- 6%, ethyl ester monoacetate, 18 +/- 7%; P < 0.05). In contrast, LSD- and AS-mediated toxicity was inversely proportional with dose (LSD, 40.3% at 0.5 mg/mL, 3.4% at 2.0 mg/mL; AS, 49% at 0.5 mg/mL, 0% at 2.0 mg/mL). Sophorolipid treatment did not affect peripheral blood mononuclear cells at all doses tested.

Example Input: Limited knowledge exists about the value of tumor size in surgically treated cervical cancer (CX) using a tumor size of 2 cm as cut-off value.', 'A total of 366 cases of CX FIGO stage IB who received upfront surgery were evaluated regarding tumor size, the prediction of pelvic lymph node involvement, and recurrence-free and overall survival during a median follow-up time of 94 months. Tumors ≤2.0 cm were defined as small, tumors 2.1-4.0 cm as medium sized and those larger than 4 cm as bulky disease.', 'Small tumors were seen in 28.7%, medium sized in 52.5% and bulky tumors in 18.9%. There was a significant higher frequency of pelvic lymph node involvement with increasing tumor size (13.3% vs. 23.4% vs. 43.5%, respectively; p<0.001) and an increase of recurrent disease (6.7% vs. 18.8% vs. 29.4%, respectively; p<0.001). The 5-year overall survival rate was significantly reduced with increasing tumor size (94.0% vs. 85.1% vs. 69.9%, respectively; p<0.001). Pelvic lymph node involvement and maximal tumor size were independent prognostic factors for both recurrence-free and overall survival in multivariate analysis.

Example Input: To prospectively investigate the presence and counts of archaea in feces of 472 children in association with weight development from 6 to 10\xa0years of age.', 'Within the KOALA Birth Cohort Study, a single fecal sample from each child was analyzed by quantitative polymerase chain reaction to quantify archaea (Methanobrevibacter smithii, Methanosphera stadtmanae). Anthropometric outcomes (overweight [body mass index {BMI}\xa0≥\xa085th percentile], age- and sex-standardized BMI, weight, and height z-scores) were repeatedly measured at ages (mean\xa0±\xa0SD) of 6.2\xa0±\xa00.5, 6.8\xa0±\xa00.5, 7.8\xa0±\xa00.5, and 8.8\xa0±\xa00.5\xa0years. Generalized estimating equation was used for statistical analysis while controlling for confounders.', 'Methanobrevibacter smithii colonization was associated with an increased risk of overweight (adjusted odds ratio [OR]\xa0=\xa02.69; 95% confidence interval [CI] 0.96-7.54) from 6 to 10\xa0years of age. Children with high levels (>7 log10 copies/g feces) of this archaeon were at highest risk for overweight (OR\xa0=\xa03.27; 95% CI 1.09-9.83). Moreover, M. smithii colonization was associated with higher weight z-scores (adj. β 0.18; 95% CI 0.00-0.36), but not with height. For BMI z-scores, the interaction (P\xa0=\xa00.008) between M. smithii and age was statistically significant, implying children colonized with M. smithii had increasing BMI z-scores with age.
