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: Preoperative chemoradiotherapy is one of the key strategies for the improvement of survival in pancreatic cancer; however, no method to predict the response has yet been established. The aim of this study was to prospectively evaluate the predictive value of REG4, a new member of the regenerating (REG) islet-derived family of proteins.', 'Stably REG4-expressing cells were established from a pancreatic cancer cell line and exposed in vitro to gamma-ray or gemcitabine to investigate the relevance of REG4 to the resistance to chemotherapy or radiotherapy. In 23 patients with resectable pancreatic cancer, the serum concentration of REG4 was measured before preoperative chemoradiotherapy, and the histologic response was evaluated after the surgery.', 'A 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and fluorescence activated cell scanning (FACS) revealed that REG4-overexpressing cells were resistant to gamma-radiation but showed a modest resistance to gemcitabine. The patients with a higher REG4 level, but not carcinoembryonic antigen or CA-19-9, showed an unfavorable histologic response to chemoradiotherapy (Spearman, rho = 0.439, P = 0.039). The patients showing a higher REG4 level experienced local recurrence postoperatively.

Example Input: Information about malaria risk factors at high altitudes is scanty. Understanding the risk factors that determine the risk of malaria transmission at high altitude villages is important to facilitate implementing sustainable malaria control and prevention programs.', 'An unmatched case control study was conducted among patients seeking treatment at health centers in high altitude areas. Either microscopy or rapid diagnostic tests were used to confirm the presence of plasmodium species. A generalized linear model was used to identify the predictors of malaria transmission in high altitude villages.', 'Males (AOR\u200a=\u200a3.11, 95%CI: 2.28, 4.23), and those who traveled away from the home in the previous month (AOR\u200a=\u200a2.01, 95% CI: 1.56, 2.58) were strongly associated with presence of malaria in high altitude villages. Other significant factors, including agriculture in occupation (AOR\u200a=\u200a1.41, 95% CI: 1.05, 1.93), plants used for fencing (AOR\u200a=\u200a1.70, 95% CI: 1.18, 2.52) and forests near the house (AOR\u200a=\u200a1.60, 95% CI: 1.15, 2.47), were found predictors for malaria in high altitude villages.

Example Input: Recent epidemiological evidence suggests that modifying lifestyle by increasing physical activity could be a non-pharmacological approach to improving symptoms and slowing disease progression in Alzheimer's disease and other tauopathies. Previous studies have shown that exercise reduces tau hyperphosphorylation, however, it is not known whether exercise reduces the accumulation of soluble or insoluble tau aggregates and neurofibrillary tangles, which are both neuropathological hallmarks of neurodegenerative tauopathy. In this study, 7-month old P301S tau transgenic mice were subjected to 12-weeks of forced treadmill exercise and evaluated for effects on motor function and tau pathology at 10\xa0months of age.", 'Exercise improved general locomotor and exploratory activity and resulted in significant reductions in full-length and hyperphosphorylated tau in the spinal cord and hippocampus as well as a reduction in sarkosyl-insoluble AT8-tau in the spinal cord. Exercise did not attenuate significant neuron loss in the hippocampus or cortex. Key proteins involved in autophagy-microtubule-associated protein 1A/1B light chain 3 and p62/sequestosome 1 -were also measured to assess whether autophagy is implicated in the exercised-induced reduction of aggregated tau protein. There were no significant effects of forced treadmill exercise on autophagy protein levels in P301S mice.
