Given the task definition and input, reply with output. 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.

IL-1 plays a vital role in the terminal processes of human labour and delivery. Inflammasome activation is required to process pro IL-1 to an active, secreted molecule. Recent studies have shown that autophagy regulates IL-1 via the inflammasome. The aims were to determine the effect of (i) human spontaneous term and preterm labour on the expression of autophagy proteins in fetal membranes; and (ii) autophagy inhibition on IL-1 release.', 'Fetal membranes, from term and preterm, were obtained from non-labouring and labouring women. Tissue explants were used to determine the effect of inhibition of autophagy on IL-1 secretion.', 'Expression of the autophagy proteins Beclin-1, Atg3, Atg5, Atg7, Atg12, Atg16L1 were lower after spontaneous term labour. Beclin-1 and Atg7 expression were lower after spontaneous preterm labour. Beclin-1, Atg3, and Atg7 expression were lower after preterm pre-labour rupture of membranes (PPROM) compared to preterm with intact membranes. LC3B-I expression was higher after spontaneous term and preterm labour and with PPROM; there was no difference in LC3B-II expression between the two groups. The autophagy inhibitor LY290042 increased IL-1 secretion in the presence of bacterial endotoxin LPS; IL-1 secretion was ameliorated in the presence inflammasome inhibitors.
