Instructions: 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.
Input: The volatile anesthetic isoflurane protects the heart from hypoxia/reperfusion (H/R) injury. However, it is still incompletely understood whether isoflurane exerts its protective role through preventing mitochondrial permeability transition pore (MPTP) opening.', 'Primary cultured cardiocytes were exposed to H/R in the absence or presence of isoflurane. Cell cytotoxicity and apoptosis were detected by MTT assay and TUNEL staining, respectively. MPTP function was monitored by confocal imaging after reoxygenation. ROS production and activation of caspase-3 were determined by fluorescent reader and western blot, respectively.', 'As compared to the control group, H/R led to significant cell cytotoxicity and apoptosis, while application of isoflurane markedly reversed the effects. Furthermore, isoflurane significantly inhibits the formation of H/R-induced excess ROS production. Finally, isoflurane attenuated the onset of mitochondrial permeability transition pore (MPTP) occurred during hypoxia/reoxygenation, and in turn inhibited activation of caspase-3.
