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: The aim of this study was to investigate the antiproliferative and cytotoxic effects of a newly synthesized molecule named paracetamol acetohydroxamic acid (PaCaHa) on human neoplastic cell lines.', 'A549, CRL 2923, HeLa, and ARPE were treated with various concentrations of PaCaHa and DMSO (vehicle control). The cytotoxic/cytostatic effects of PaCaHa were determined after a 24-h incubation period and compared to the DMSO control. The cytotoxic and antiproliferative effects were determined by the trypan blue dye exclusion and MTT methods.', 'A higher susceptibility to PaCaHA was found in CRL 2923 and HeLa cells, while A549 and ARPE cells were less responsive to PaCaHa. The percent of cytotoxicity resulting from 400 µg/mL of PaCaHa were >90 for CRL-2923 and HeLa, 68 for A549, and 64 for ARPE cells. The cytotoxic difference between CRL-2923/HeLa and ARPE/A549 cells was significant (P < 0.05).

Example Input: To investigate the relationship between the damages of hand functions and the type of cerebral palsy (CP) in children with CP.', 'A total of 280 children aged 4-12 years old with CP in the 20 districts of Chengdu were included. The damages of hand functions were assessed with the Chinese Version of Manual Ability Classification System (MACS) and its relationship with the type of CP were analyzed.', 'Among the 280 investigated children, there were 195 chidren with spastic CP, which accounted for the largest proportion (69.64%), wherein the spastic diplegia was most common (56.41%). The classification of MACS was level I-II in 65.13% children with spastic CP, whereas the classification of MACS was level IU-V in 84. 44% and 80.95% children with mixed and dyskinetic CP, respectively. With the increase of the degree of cognitive dysfunction in children with CP, the level of MACS was also increased. There was a difference between the classification of MACS and the different type of CP (P<0.05). The children with spastic CP were mostly mild hand dysfunction, while the children with mixed and dyskinetic type of CP were mostly middle and severe hand dysfunction. A positive correlation was found between the MACS and the subtype of spastic CP (r=0.541, P<0.05). In most of the children with diplegia from spastic CP, the hand dysfunction was mild, whereas the children with quadriplegia from spastic CP were mostly middle and severe hand dysfunction.

Example Input: Recent studies have indicated a protective role of physiological autophagy in ischemic heart disease. However, the underlying mechanisms of autophagy regulation after ischemia are poorly understood. Exosomes are nano-sized vesicles released from cells that play critical roles in mediating cell-to-cell communication through the transfer of microRNAs. In this study, we observed that miR-30a was highly enriched in exosomes from the serum of acute myocardial infarction (AMI) patients in vivo and culture medium of cardiomyocytes after hypoxic stimulation in vitro. We also found that hypoxia inducible factor (HIF)-1α regulates miR-30a, which efficiently transferred via exosomes between cardiomyocytes after hypoxia. Inhibition of miR-30a or release of exosomes increased the expression of the core autophagy regulators beclin-1, Atg12, and LC3II/LC3I, which contributed to maintaining the autophagic response in cardiomyocytes after hypoxia. Taken together, the present study showed that exosomes from hypoxic cardiomyocytes regulate autophagy by transferring miR-30a in a paracrine manner, which revealed a new pathway of autophagy regulation that might comprise a promising strategy to treat ischemic heart disease.
