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: Evidence regarding the mortality rate after administration of the pandemic influenza A (H1N1) 2009 vaccine on patients with underlying diseases is currently scarce. We conducted a case-control study in Japan to compare the mortality rates of patients with idiopathic interstitial pneumonia after the vaccines were administered and were not administered.', 'Between October 2009 and March 2010, we collected clinical records in Japan and conducted a 1:1 matched case-control study. Patients with idiopathic interstitial pneumonia who died during this period were considered case patients, and those who survived were considered control patients. We determined and compared the proportion of each group that received the pandemic influenza A (H1N1) 2009 vaccine and estimated the odds ratio. Finally, we conducted simulations that compensated for the shortcomings of the study associated with adjusted severity of idiopathic interstitial pneumonia.', 'The case and control groups each comprised of 75 patients with idiopathic interstitial pneumonia. The proportion of patients who received the pandemic influenza A (H1N1) 2009 vaccine was 30.7% and 38.7% for the case and control groups, respectively. During that winter, the crude conditional odds ratio of mortality was 0.63 (95% confidence interval, 0.25-1.47) and the adjusted conditional odds ratio was 1.18 (95% confidence interval, 0.33-4.49); neither was significant. The simulation study showed more accurate conditional odds ratios of 0.63-0.71.

Example Input: To investigate whether tafluprost, which is a prostaglandin-related compound and an anti-glaucoma drug, has a direct anti-apoptotic effect in cultured retinal ganglion cells (RGCs) and rat RGCs in retinas with optic nerve crush (ONC).', 'RGC-5 cells were induced to undergo apoptosis by a serum deprivation and by exogenous glutamate. The level of cell death with or without tafluprost was monitored by an XTT assay and by immunocytochemistry with activated caspase-3. Changes in intracellular calcium ([Ca(2+)]i) levels were measured with fluo-4 fluorescence. Rat RGCs were degenerated by ONC. After topical instillation of tafluprost for 7 and 14 days, the numbers of retrograde-labeled RGCs were counted. Retinal flatmounts were subjected to terminal dUTP nick end labeling (TUNEL) staining to detect apoptotic cells.', 'Tafluprost dose-dependently promoted RGC-5 cell viability with an optimum concentration of 3 microM (p = 0.006). Tafluprost significantly reduced caspase-3-positive cells and suppressed [Ca(+2)]i evoked by exogenous glutamate. The cGMP-dependent protein kinase inhibitor and KT-5823 partially blocked the rescue effect of tafluprost (p = 0.002). The survival rate of RGCs significantly increased in eyes treated with tafluprost (p = 0.01), and the prevalence of TUNEL-positive cells was significantly decreased 14 days after ONC (p < 0.001).

Example Input: Functional stimulation is accompanied by increases in regional cerebral blood flow which exceed metabolic demands under normal circumstances, but it is unknown whether functional stimulation is beneficial or detrimental in the setting of acute ischemia. The aim of this study was to determine the effect of forepaw stimulation during temporary focal ischemia on neurological and tissue outcome in a rat model of reversible focal forebrain ischemia.', 'Sprague-Dawley rats were prepared for temporary occlusion of the right middle cerebral artery (MCA) using the filament model. Cerebral blood flow in the MCA territory was continuously monitored with a laser-Doppler flowmeter. Subdermal electrodes were inserted into the dorsal forepaw to stimulate either the forepaw ipsilateral or contralateral to the occlusion starting 1 minute into ischemia and continuing throughout the ischemic period. A neurological evaluation was undertaken after 24 hours of reperfusion, and animals were then euthanized and brain slices stained with 2,3,5-triphenyltetrazolium chloride. Cortical and striatal damage was measured separately.', 'The cortical and striatal infarct volumes were both significantly reduced in the contralateral stimulated group compared with the ipsilateral stimulated group (48% total reduction). There were no statistically significant differences in the neurobehavioral scores between the 2 groups, or in the laser-Doppler flow measurements from the MCA core.
